[0001] This utility model relates to the field of industrial filter element cleaning technology, specifically to a high-efficiency air-water mixing filter element cleaning device. Background Technology

[0002] With the continuous rise of new materials and fine chemicals, the requirements for material cleanliness are becoming increasingly stringent. To ensure media cleanliness, various types of filters have emerged. After a period of use, a large amount of impurities will accumulate on the surface of the filter element. If the filter element is not replaced in time, it will cause filter blockage, reduce filtration efficiency, and increase resistance. However, frequent replacement of new filter elements is extremely costly, so a filter element cleaning device is needed. Utility Model Content

[0003] The purpose of this invention is to solve the problem that existing filter elements accumulate a large amount of impurities on their surface after a period of use, affecting the filtration effect and requiring replacement, which is costly due to frequent replacement of new filter elements.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-efficiency air-water mixing filter element cleaning device, characterized in that: it includes a cleaning chamber, a clamping assembly for clamping the filter element to be cleaned and driving it to rotate, and a cleaning assembly for cleaning the filter element;

[0006] The clamping assembly includes a first clamping plate and a second clamping plate of the filter element symmetrically arranged on both sides of the cleaning chamber. The first clamping plate of the filter element is rotatably connected to one end of the clamping screw opposite to the end face of the second clamping plate of the filter element. The other end of the clamping screw extends out of the cleaning chamber and is fixedly connected to a clamping handwheel. The clamping screw is threadedly connected to the side wall of the cleaning chamber.

[0007] The cleaning assembly includes a flushing pipe for rinsing the filter element to be cleaned and several cleaning brushes adjustablely disposed in a cleaning chamber on one side of the filter element to be cleaned. The flushing pipe is fixedly sleeved in the middle of the second pressing plate of the filter element. One end of the flushing pipe opposite to the first pressing plate of the filter element is fixedly connected to one end of a rotating handle. The other end of the rotating handle extends out of the side wall of the cleaning chamber. The outer peripheral wall of the end of the flushing pipe opposite to the first pressing plate of the filter element is connected to a water inlet pipe and an air inlet pipe through a rotating joint. The water inlet pipe and the air inlet pipe extend out of the side wall of the cleaning chamber. Several flushing outlets are provided on the other end face and the outer peripheral wall of the flushing pipe.

[0008] A further improvement is that: one end of the cleaning brush is fixedly connected to the end of the filter element to be cleaned away from the cleaning brush, and the other end of the brush rod extends out of the cleaning box and is fixedly connected to the brush adjusting handwheel; the brush rod is threadedly connected to the side wall of the cleaning box.

[0009] A further improvement is that the several flushing outlets are evenly distributed.

[0011] A further improvement is that an intake valve is installed on the intake pipe.

[0012] A further improvement is that an exhaust pipe is connected to the upper end of one side of the cleaning chamber. This allows for the recovery and treatment of any toxic or harmful gases generated during the cleaning process via the exhaust pipe.

[0013] A further improvement is that a wastewater collection pipe is connected to the bottom of the cleaning chamber on one side of the first pressing plate of the filter element. The wastewater collection pipe is used to collect the wastewater from rinsing.

[0014] A further improvement is that a sewage collection pipe valve is installed on the sewage collection pipe.

[0015] Compared with existing technologies, the above technical solution has the following advantages:

[0016] Deep cleaning: Gas (such as compressed air) creates turbulence inside the filter element, stripping away deep-seated dirt; water flow quickly carries away the loosened impurities, especially effective against viscous contaminants (such as oil and biofilm); Extended lifespan: After effective cleaning, filter elements with reversible contamination (such as particle clogging) can achieve a flow recovery rate of 80%–90%, reducing the frequency of filter element replacement; Water-saving and efficient: Compared to pure water backwashing, the air washing stage reduces water consumption by 30%–50%, suitable for scenarios with limited water resources; More environmentally friendly: A wastewater collection pipe is installed to recycle and treat wastewater, preventing water pollution; Potentially toxic or harmful gases can be collected and treated through the exhaust pipe, reducing air pollution; More uniform flushing water: Several flushing outlets are evenly distributed, resulting in more uniform air and water distribution during flushing, effectively preventing negative pressure suction inside the filter element and uneven air and water distribution; Combined air and water flushing has a significant cleaning effect on pressure-resistant filter elements (such as sintered metals and ceramics), and can deeply restore the filter element's flowability.

Detailed Implementation

[0023] See Figures 1-4 As shown, the technical solution adopted in this specific embodiment is: a high-efficiency air-water mixing filter element cleaning device, including a cleaning chamber 1, a clamping component for clamping the filter element to be cleaned and driving it to rotate, and a cleaning component for cleaning the filter element.

[0024] The clamping assembly includes a first filter element clamping plate 2 and a second filter element clamping plate 3 symmetrically arranged on both sides inside the cleaning chamber 1. The first filter element clamping plate 2 is rotatably connected to one end of a clamping screw 21 away from the second filter element clamping plate 3. The other end of the clamping screw 21 extends out of the cleaning chamber 1 and is fixedly connected to a clamping handwheel 22. The clamping screw 21 is threadedly connected to the side wall of the cleaning chamber 1.

[0025] The cleaning assembly includes a flushing pipe 5 for rinsing the filter element to be cleaned and several cleaning brushes 6 adjustablely disposed in a cleaning chamber 1 on one side of the filter element to be cleaned. The flushing pipe 5 is fixedly sleeved in the middle of the second pressing plate 3 of the filter element. One end of the flushing pipe 5 away from the first pressing plate 2 of the filter element is fixedly connected to one end of a rotating handle 4. The other end of the rotating handle 4 extends out of the side wall of the cleaning chamber 1. The outer peripheral wall of the end of the flushing pipe 5 away from the first pressing plate 2 of the filter element is connected to a water inlet pipe 51 and an air inlet pipe 52 through a rotating joint 53. The water inlet pipe 51 and the air inlet pipe 52 extend out of the side wall of the cleaning chamber 1. Several flushing outlets 54 are provided on the other end face and the outer peripheral wall of the flushing pipe 5.

[0026] The cleaning brush 6 is fixedly connected to one end of a brush rod 61 at the end face away from the filter element to be cleaned. The other end of the brush rod 61 extends out of the cleaning box 1 and is fixedly connected to a brush adjusting handwheel 62. The brush rod 61 is threadedly connected to the side wall of the cleaning box 1.

[0027] Among them, several of the flushing outlets 54 are evenly distributed.

[0028] The water inlet pipe 51 is equipped with a water inlet valve 511.

[0029] An intake valve 521 is provided on the intake pipe 52.

[0030] The cleaning chamber 1 is equipped with an exhaust pipe 8 connected to the upper end of one side. If toxic or harmful gases are generated during the cleaning process, they can be recovered and treated through the exhaust pipe 8.

[0031] The bottom of the cleaning chamber 1 on one side of the first pressing plate 2 of the filter element is connected to a sewage collection pipe 7. The sewage collection pipe 7 is used to collect the sewage from rinsing.

[0032] The sewage collection pipe 7 is equipped with a sewage collection pipe valve 71.

[0033] Air pressure control during different filter cartridge flushing processes:

[0034] Metal / ceramic filter element: air pressure ≤0.3MPa, to avoid weld cracking or filter material fatigue;

[0035] Hollow fiber membrane: air pressure ≤ 0.05MPa, combined with intermittent aeration (e.g., aeration for 10 seconds / stop for 20 seconds).

[0036] Water flow coordination during rinsing:

[0037] The water pressure should be lower than the maximum withstand pressure of the filter element (e.g., 0.2-0.5 MPa), and the gas and liquid volumes should be matched to prevent excessive gas resistance from damaging the internal components of the filter element.

[0038] Suitable filter cartridge types for air-water flushing include porous sintered filter cartridges (such as PE and ceramic filter cartridges): combined air-water flushing can remove particulate matter or biofilm adhering to the pores through bubble bursts and water flow shear force, restoring flux. A row of adjustable brushes is set on one side. During the flushing process, the corresponding adjustment handwheel is rotated to make the brushes contact the filter cartridge. During the flushing process, the handle is rotated to make the filter cartridge rotate and clean in the cleaning tank, so as to achieve the cleaning purpose more quickly. The flushing wastewater can be collected through the sewage collection pipe, or the toxic and harmful gases can be discharged and treated through the exhaust pipe. After the flushing is completed, the water valve is closed, and the residual water stains on the filter cartridge can be blown away by air.

[0039] Metal filter element (stainless steel sintered filter screen): Resistant to high pressure and mechanical impact, suitable for strong air and water backwashing. Combined with brush and rotary rinsing, it can clean surface deposits more thoroughly. It is especially effective for grease and colloidal contaminants. Degreasing agents can be added to the water to enhance the rinsing effect. The rinsing wastewater is recycled and treated through the drain outlet. After rinsing, the water valve is closed, and the filter element is blown away with air to remove residual water stains.

[0040] The working principle of this utility model is as follows: In use, the filter element to be cleaned is placed into the cleaning chamber. One end of the filter element abuts against the second filter element pressing plate, and the other end is pressed by the pressing handwheel, which drives the first filter element pressing plate to move towards the filter element. By opening the corresponding valve, water and air, or water and air together, are introduced into the flushing pipe and flushed into the filter element through the flushing outlet. The air and water are flushed together, and the flushed gas is dried. By rotating the corresponding brush adjusting handwheel, the brush is moved towards the filter element, so that the brush contacts the filter element. By rotating the handle, the filter element is rotated in the cleaning chamber for uniform cleaning. The flushing wastewater can be collected through the sewage collection pipe, or the toxic and harmful gases can be discharged and treated through the exhaust pipe. After flushing, the water valve is closed, and the filter element can be blown away with gas to remove residual water stains.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model.
