The suction self - cleaning filter, featuring an innovative suction - based cleaning mechanism and high - efficiency filtration technology, provides reliable and continuous purification for various fluids. It ensures stable operation and superior performance, making it the ideal choice for multiple industrial and civil applications.
The suction self - cleaning filter is an advanced filtration device that combines high - performance filtration with an intelligent self - cleaning system. The core of the filter consists of a high - quality filter element, usually made of stainless - steel mesh or high - density filter fabric, which effectively intercepts suspended solids, colloids, rust, and other impurities in the fluid. During normal filtration, the fluid to be treated enters the filter housing and passes through the filter element from the outside to the inside. The purified fluid then flows out from the outlet for subsequent use. When the impurities accumulate on the filter element and cause the pressure difference between the inlet and outlet to reach a preset value (commonly 0.05 - 0.1MPa) or the operation time reaches a set duration (such as 8 - 24 hours), the self - cleaning process is triggered. Through a unique suction - based cleaning mechanism, the filter element is cleaned without manual disassembly, ensuring long - term stable filtration efficiency and reducing maintenance workload. This makes the suction self - cleaning filter suitable for industries like water treatment, chemical processing, and food production, where continuous and reliable filtration is required.
Normal Filtration Phase
Fluid Inflow: The fluid enters the filter through the inlet port. Under the driving force of the system pressure, it evenly distributes around the outer surface of the filter element.
Filtration: As the fluid permeates from the outside to the inside of the filter element, various impurities are retained on the outer surface of the element due to the interception effect of the filter media. The purified fluid passes through the element and converges towards the outlet, ready to be transported to the next process.
Self - Cleaning Trigger
Pressure Difference Trigger: With the continuous filtration, impurities gradually build up on the filter element, increasing the flow resistance and thus the pressure difference between the inlet and outlet of the filter. Once this pressure difference reaches the pre - set threshold (0.05 - 0.1MPa), it serves as a signal to start the self - cleaning process.
Time - Based Trigger: In cases where the fluid quality is relatively good and the pressure difference does not rise significantly, the filter initiates self - cleaning based on a pre - determined operation time (e.g., 8 - 24 hours). This regular cleaning schedule helps maintain the optimal performance of the filter element.
Self - Cleaning Process
Suction Nozzle Positioning: When the self - cleaning process starts, a precisely designed suction nozzle moves to the position close to the surface of the filter element. The movement of the suction nozzle is controlled by a motor - driven mechanism, ensuring accurate positioning.
Suction Cleaning: High - pressure fluid (usually clean backwash water or compressed air) is introduced into the suction nozzle. This creates a strong suction force that sucks away the impurities attached to the surface of the filter element. The sucked - away impurities are then carried away by the fluid flow and discharged from the filter through a dedicated 排污口. In some models, the suction nozzle may rotate or move along the surface of the filter element to ensure comprehensive cleaning of the entire element.
Flushing and Rinsing: After the suction process, a flushing stage may follow. Clean water is used to rinse the filter element and the internal channels of the filter, ensuring that no residual impurities remain. This step helps to restore the original filtration performance of the filter element.
Filtration Resumption Phase
Once the self - cleaning process is completed, the suction nozzle returns to its initial position, and the filter resumes its normal filtration operation. The inlet and outlet valves return to their normal states, ensuring a continuous supply of purified fluid.

How does the suction self - cleaning filter ensure the cleaning effect?
The filter uses a high - pressure fluid - driven suction nozzle to create a strong suction force, which can effectively suck away impurities attached to the filter element surface. The precise movement control of the suction nozzle ensures comprehensive cleaning of the entire filter element. Additionally, the flushing and rinsing steps after suction help to thoroughly remove any remaining impurities, ensuring the restoration of the filter element's filtration performance.
Can the filter element of the suction self - cleaning filter be replaced?
Yes, although the self - cleaning function significantly extends the service life of the filter element, it can still be replaced when necessary.
