INTRODUCTION

The filter housing is usually made of high-quality carbon steel or stainless steel, possessing good pressure resistance and corrosion resistance. It can adapt to various working environments and provides stable protection for the internal filter basket. The filter basket, as the core filtering element, is generally made of stainless steel wire mesh or perforated plates with specific mesh specifications that can be customized according to different filtration precision requirements. It is mostly in a cylindrical shape and placed inside the filter, capable of effectively intercepting large-particle impurities, suspended solids, and other substances in water.

The design of the water inlet and outlet ports is scientific and reasonable, ensuring smooth water flow in and out of the filter. The sewage outlet is convenient for discharging the impurities intercepted during the filtration process. This equipment comes in a variety of specifications and can be flexibly selected according to factors such as the water treatment volume, installation space, and specific filtration requirements. It is widely used in many fields such as industry, municipal, and chemical industries. It is easy to install, simple to operate, and runs stably and reliably, making it one of the common choices for ensuring water quality and protecting the normal operation of subsequent equipment.

WORKING PRINCIPLE

The working principle of strainer basket filters is based on the physical interception effect of the filter basket. When water containing impurities enters the filter through the inlet port, under the impetus of the water flow, the water will flow towards the filter basket placed inside the filter.

Due to the specific mesh size of the filter basket, impurities in the water with particle sizes larger than the mesh, such as sediment, rust, lumps of debris, and larger suspended solids, will be intercepted inside the filter basket and cannot continue to pass through with the water flow. However, water and substances with particle sizes smaller than the mesh can smoothly pass through the filter basket and flow out from the outlet port, thus achieving the preliminary filtration of the raw water. This removes the visible impurities in the water that may cause clogging, wear, or affect the water quality of subsequent equipment, making the filtered water purer and providing a relatively clean water source basis for subsequent water use links or further water treatment processes.

MAIN PERFORMANCE AND CHARACTERISTICS

l High-Efficiency Interception Capacity: Thanks to the customized mesh specifications of the filter basket, it has an excellent interception effect on common large-particle impurities in water. Whether it is metal scraps in industrial water, rust from pipes, or sediment and debris in municipal water supply, they can all be effectively blocked inside the filter basket, significantly reducing the impurity content in water, ensuring the cleanliness and safety of subsequent water use, and meeting the basic requirements for water quality in different scenarios.

l Stable and Reliable Operation: The combination of high-quality housing materials and a reasonable structural design enables it to operate stably under complex working conditions such as different water flow pressures, changes in water quality, and temperature fluctuations. It is not prone to leakage, deformation, and other malfunctions, continuously providing a stable and up-to-standard water quality guarantee for the entire water use system, reducing production interruptions or water quality fluctuations caused by equipment problems, and the maintenance cost is also relatively low.

l Simple Structure and Easy Maintenance: The overall structure is relatively straightforward and simple. Each component is easy to identify and operate. When too many impurities accumulate in the filter basket and need to be cleaned, just open the cover of the filter, take out the filter basket for rinsing or replacement, without the need for complex professional tools and cumbersome operation procedures. Ordinary staff can complete the maintenance work after simple training, which greatly facilitates the daily management of the equipment.

l High Application Flexibility: Different specifications of the filter basket, housing size, and installation methods of the equipment can be flexibly selected according to different water source qualities, treatment water volumes, and specific application scenarios. It can be used in conjunction with various other water treatment equipment. Whether it is in the filtration of cooling water in industrial production, the pretreatment of chemical raw materials, the preliminary purification of municipal water supply, or the front-end link of sewage treatment, it can play an important role, has strong versatility, and can meet diverse water treatment requirements.

l Cost-Effective: Compared with some high-precision and complex filtering equipment, strainer basket filters have a cost advantage while achieving basic filtration effects. The purchase price of the equipment is relatively low, and the subsequent operation and maintenance costs are also not high. For users who value cost performance and do not have extremely high requirements for filtration precision, it is an ideal choice.

APPLICATION FIELDS AND INDUSTRIES

l Industrial Field: In industries such as machinery manufacturing and the automotive industry, a large amount of industrial water containing metal scraps, chips, and other impurities is generated during the production process. Strainer basket filters can filter these cooling waters, lubricating waters, etc., intercept impurities, prevent them from entering the cooling systems and lubricating systems of equipment, avoid clogging and wear problems, ensure the normal operation of production equipment, and extend the service life of the equipment. In the chemical industry, it can also conduct preliminary filtration on some chemical raw material liquids, remove large-particle impurities in them, provide purer raw materials for subsequent chemical reactions, purification, and other processes, and improve product quality.

l Municipal Water Supply Field: The source water for municipal water supply often contains impurities such as sediment, algae, microorganisms, and some floating objects. Strainer basket filters, as important equipment in the pretreatment process, can quickly and effectively remove large-particle suspended solids in the water, reduce the burden on subsequent in-depth treatment processes, improve the processing efficiency of the entire water supply system, ensure the safety and hygiene of residents' water use, enable residents to use clearer and odorless drinking water, and also help to reduce the maintenance cost of the water supply pipeline caused by the deposition of impurities and extend its service life.

l Sewage Treatment Field: In the treatment of domestic sewage and industrial wastewater, strainer basket filters can first conduct preliminary filtration on the sewage, remove large-particle debris, lumps of garbage, etc., avoid these impurities from clogging or damaging subsequent biochemical treatment equipment, membrane treatment equipment, and other equipment, improve the efficiency of the entire sewage treatment system, enable the subsequent biochemical treatment, advanced treatment, and other processes of the sewage to proceed more smoothly, and finally achieve the goals of meeting the discharge standards or recycling the sewage, which has a positive significance for the rational utilization of water resources and environmental protection.

l Food and Beverage Industry: The production of food and beverages has extremely high requirements for water quality. Although strainer basket filters are mainly used to remove large-particle impurities, as preliminary filtering equipment at the front end, they can intercept visible impurities such as sediment and leaves in water, prevent these impurities from entering subsequent finer filtering links or production processes, ensure the cleanliness of the entire production water, indirectly improve the quality and hygiene standards of products, and meet the strict requirements of the industry.

SUMMARY

Strainer basket filters, with their unique structure, reliable working principle, and many excellent performance characteristics, have shown indispensable value in many important fields such as industry, municipal, sewage treatment, and the food and beverage industry. They are like the 'filter nets' for efficiently intercepting impurities in water quality, quietly contributing to ensuring the cleanliness and efficient utilization of water resources, helping to stabilize the development of various industries and improve people's living quality. With the continuous progress of science and technology, it is believed that strainer basket filters will continue to make breakthroughs in aspects such as improving filtration precision, optimizing materials, and expanding applications, further meeting the increasingly diverse water treatment needs of society and becoming one of the important supporting equipment for creating a high-quality water environment and promoting sustainable development.
