Suction Self Cleaning Filter - Powerful Debris Absorption & Intelligent Self - Cleaning Filtration Expert

Product Introduction

1. Structural Composition

• Filtration Unit: Equipped with high - precision stainless steel filter screens or composite filter elements. The screen aperture can be customized according to requirements, effectively intercepting various impurities ranging from 5 to 500 microns.

• Suction Cleaning Device: A movable suction nozzle is  built - in, which removes impurities on the surface of the filter screen through negative pressure suction, ensuring thorough cleaning.

• 
  

• Drive System: Composed of a motor and a transmission mechanism, it drives the suction nozzle to move back and forth on the surface of the filter screen for comprehensive cleaning.

• Control System: Integrated with an intelligent PLC control system, it monitors parameters such as the pressure difference between the inlet and outlet of the filter, flow rate, and operation time in real - time, and automatically controls the cleaning process.

2. Working Principle：When the fluid to be filtered enters the filter, it is filtered through the filter screen, and impurities are intercepted on the surface of the screen. When the accumulation of impurities on the screen surface causes the pressure difference between the inlet and outlet to reach the set value, or the operation time reaches the preset duration, the control system activates the drive system, moving the suction nozzle while turning on the negative pressure device. The impurities on the screen surface are sucked away by the suction force and discharged through the sewage pipe, realizing automatic cleaning of the filter without shutdown.

3. Core Advantages：Compared with traditional filters, the suction self - cleaning filter has higher cleaning efficiency, capable of deeply removing stubborn impurities. It can perform online self - cleaning to ensure continuous system operation. The intelligent control reduces manual maintenance costs, and it is suitable for various complex working conditions.

Working Process

1. Fluid Filtration

• The fluid to be filtered flows into the filter from the inlet and evenly passes through the filter screen, where suspended solids, particulate impurities, colloids, etc., are intercepted.

• The filtered clean fluid flows out from the outlet and enters subsequent processing or use processes.

2. Cleaning Trigger

• The control system monitors the pressure difference between the inlet and outlet of the filter and the operation time in real - time.

• When the pressure difference exceeds the set threshold (such as 0.05 - 0.1MPa), or the operation time reaches the preset duration (such as 8 - 24 hours), the self - cleaning program is triggered.

3. Self - Cleaning Process

• The drive system starts, driving the suction nozzle to move back and forth along the surface of the filter screen.

• The negative pressure device is turned on, generating a strong suction force to adsorb the impurities on the screen surface into the suction nozzle.

• The impurities are transported to the sewage outlet through the pipeline and discharged from the filter.

• The cleaning process covers the entire filter screen according to the set path to ensure no cleaning dead angles. The single - cycle cleaning time is about 30 - 120 seconds.

4. Resumption of Operation：After the self - cleaning is completed, the drive system stops, the negative pressure device is turned off, and the filter re - enters the filtration stage to continuously purify the fluid.

FAQ

1. How to maintain the suction nozzle of the suction self - cleaning filter?：During daily use, regularly check whether the connecting pipes of the suction nozzle are blocked or damaged to avoid affecting the suction force. Disassemble and clean the nozzle every 3 - 6 months to remove residual impurities inside and prevent blockage. If the suction force of the nozzle decreases significantly, check whether the negative pressure device is working properly and replace relevant components if necessary.

2. How to select a suitable model of the suction self - cleaning filter according to actual working conditions?：First, determine the specifications of the filter according to the processing flow rate to ensure that the equipment can meet actual needs. Then, select appropriate filter screens and materials based on the fluid properties (such as corrosiveness and viscosity). Finally, choose a suitable model by combining working pressure, temperature, and other parameters, as well as the required filtration precision. For complex working conditions, you can contact the manufacturer to customize an exclusive solution.
