Overview
The modular self-cleaning filter is a filtration equipment that combines advanced technology and features a high degree of automation and intelligence. It is increasingly widely used in the fluid processing of numerous industries. It can effectively intercept and remove various impurities in liquids or gases, such as particles, suspended solids, colloids, and fibers. It can adapt to different working conditions, ensure the purity of fluids, and provide high-quality media for subsequent production and use processes. It plays an important role in many fields, including industrial production, municipal water supply, sewage treatment, and food and beverage processing.
Working Principle
I. Fluid Inflow Stage:
The fluid (liquid or gas) to be filtered enters the inlet end of the modular self-cleaning filter through the corresponding inlet pipe, relying on its own pressure or external pumping force. After entering the interior of the filter, it will first pass through a flow equalizing device, which can evenly distribute the fluid in the filtering area of the filter, avoiding the influence on the filtering effect due to uneven local flow velocity, and ensuring that the fluid can comprehensively and smoothly contact the filtering elements.
II. Filtration Process Stage:
The modular self-cleaning filter is equipped with multiple filtering modules inside. These filtering modules are usually composed of high-precision filter screens or filter cartridges and other filtering elements, which have specific pore size specifications and can be selected and assembled according to different filtration accuracy requirements. When the fluid flows through the filtering modules, impurities with particle sizes larger than the pore size of the filtering elements will be intercepted on the surface of the filter screen or filter cartridge, while the clean fluid can pass through smoothly and be discharged from the outlet of the filter, realizing the preliminary separation of the fluid and impurities.
III. Self-Cleaning Trigger and Execution Stage:
As the filtration continues, the impurities retained on the surface of the filtering elements will continue to increase, resulting in a gradual increase in the filtration resistance. When the preset trigger conditions are met (such as when the pressure difference between the inlet and outlet reaches the set value or the filtration flow rate drops to a certain level), the self-cleaning system of the filter will automatically start. The self-cleaning system generally drives the motor through the built-in control program to drive the sewage discharge device and cleaning components to start working. The sewage discharge device will first open the corresponding sewage discharge valve, and then the cleaning components will perform operations such as flushing, brushing, or backwashing on the filtering elements to remove the impurities attached to the surface of the filtering elements. The removed impurities will be discharged out of the filter through the sewage discharge pipe. The entire self-cleaning process requires little manual intervention and is efficient and convenient.
IV. Recovery Operation Stage:
After the self-cleaning operation is completed, the sewage discharge valve is closed, and the filter automatically returns to the normal filtering working state, continuing to filter the incoming fluid, and repeating this cycle to ensure that the filter can operate stably for a long time and continuously provide a pure fluid medium for the production process.
Performance Characteristics
I. High-Efficiency Filtration and Strong Self-Cleaning Ability:
It has a high-precision filtering effect and can accurately intercept impurities of different particle sizes, ensuring that the outflowing fluid has a high purity. Meanwhile, its self-cleaning function is very powerful and highly automated. It can automatically start the cleaning process in a timely manner according to the actual operation situation, avoiding a significant decrease in the filtering efficiency caused by the accumulation of impurities and the trouble of frequent manual cleaning, greatly improving the continuous operation ability and overall working efficiency of the equipment.
II. High Degree of Intelligence:
Equipped with an advanced control system, it can monitor various parameters (such as inlet and outlet pressures, flow rates, temperatures, etc.) in the filtering process in real time, and automatically judge when to start self-cleaning, adjust operating parameters, etc. according to the set logical rules. It can also realize remote monitoring and operation, which is convenient for managers to grasp the operation status of the equipment at any time and make corresponding adjustments and decisions in a timely manner, improving the intelligent level of equipment management.
III. Obvious Advantages of Modular Design:
Adopting a modular structural design, each filtering module is relatively independent and can be flexibly combined, which makes it extremely convenient for equipment installation, capacity expansion, maintenance, and component replacement. The number of filtering modules can be flexibly increased or decreased according to the actual processing flow, filtration accuracy and other requirements, or the faulty modules can be repaired or replaced separately without affecting the normal operation of other modules, greatly reducing the maintenance cost and downtime of the equipment.
IV. Adaptation to Multiple Working Conditions:
It can handle liquids or gases with different properties (such as acidic, alkaline, neutral), and can work normally under a wide range of temperature, pressure, and different flow fluctuations. Whether in the harsh environment of industrial production or the relatively mild working conditions of municipal water supply, it can stably play its filtering role, showing strong adaptability and universality.
V. Low Operating Cost:
On the one hand, due to the self-cleaning function, the frequency of manual cleaning and the frequent replacement of filtering elements are reduced, thereby reducing labor costs and consumable costs. On the other hand, the stable operation of the equipment ensures the smooth progress of the production process, reduces the occurrence of production interruptions caused by filtering problems, and indirectly reduces production costs. In the long run, it has good cost-effectiveness.
Structural Components
I. Outer Shell:
The outer shell is generally made of high-strength stainless steel, carbon steel and other materials and formed through welding, assembly and other processes. It has good sealing performance and can effectively prevent fluid leakage. At the same time, it has sufficient strength to bear the pressure generated by the internal filtering modules, fluids, and the operation process, ensuring the safety and stability of the equipment under various working conditions. The shape of the outer shell is diverse, commonly square, cylindrical, etc., and its appearance is usually treated with anti-corrosion and anti-rust measures to make it more beautiful and durable.
II. Filtering Modules:
This is the core part for realizing the filtering function, which is composed of filter screens, filter cartridges and corresponding support structures. The material of the filter screen or filter cartridge is selected according to the characteristics and requirements of the filtering medium, such as stainless steel wire mesh, polyester fiber filter cartridge, etc., and the pore size can be customized according to requirements to meet different filtration accuracy requirements. The filtering modules are combined together through a reasonable connection method to jointly form a complete filtering system.
III. Flow Equalizing Device:
Located inside the inlet end of the filter, its function is to evenly distribute the incoming fluid in front of each filtering module, so that the fluid enters the filtering area at a uniform flow velocity and flow rate, avoiding the situation where the local fluid flow velocity is too fast or too slow, ensuring that each filtering module can perform filtering work under the best working conditions, thereby improving the overall filtering effect.
IV. Self-Cleaning System:
The self-cleaning system includes a motor, a sewage discharge device, cleaning components (such as brushes, nozzles, etc.) and a control unit. The motor provides power for the cleaning action, drives the sewage discharge device to open or close the sewage discharge valve and drives the cleaning components to perform corresponding cleaning operations on the filtering elements; the sewage discharge device is responsible for discharging the cleaned impurities out of the filter; the cleaning components clean the filtering elements in an appropriate way; the control unit judges whether to start self-cleaning and controls the orderly progress of the entire cleaning process by receiving parameter information from sensors and according to the preset program logic.
V. Inlet and Outlet Pipes and Valves:
The inlet pipe is responsible for introducing the fluid to be filtered into the interior of the filter. The diameter of the inlet pipe is designed according to the actual flow demand and is connected to the external fluid transmission pipe through an appropriate connection method (such as flange connection, threaded connection, etc.) to ensure that the fluid can enter smoothly. The outlet pipe is used to discharge the clean fluid after filtration. The same needs to consider the matching of the pipe diameter and flow rate and the convenience of connection with the subsequent pipe. Valves are installed on the inlet and outlet pipes to control the inflow and outflow of the fluid. Through the opening and closing operations of the valves, the start, stop and flow regulation of the filtering process can be realized.
Application Cases
I. Industrial Production Field:
In heavy industrial production such as chemical, petrochemical, and steel industries, the production process involves a large amount of fluid media, such as various process waters, circulating waters, raw material liquids, and process gases. These fluids often contain many impurities. If they are not effectively filtered, they will cause damage such as corrosion and blockage to equipment, affecting production efficiency and product quality. The modular self-cleaning filter can perform real-time filtering and automatic cleaning on these fluids, ensuring the purity of the fluids, extending the service life of the equipment, and improving the stability and continuity of production. For example, in chemical production, it can effectively filter out impurities in the reaction raw material liquid, ensuring the smooth progress of chemical reactions and the stability of product quality.
II. Municipal Water Supply System:
Municipal water supply needs to provide clean and safe drinking water for the general public. During the transportation of source water, impurities such as silt, rust, and suspended solids may be mixed in. The modular self-cleaning filter installed on the water supply pipe can continuously filter the raw water to remove impurities in it, and its self-cleaning function can ensure
