[0038] In the integrated filter cartridge cleaning device of this embodiment, the soaking unit 1 includes a soaking tank 11 and a valve assembly 12 connected to and installed at the bottom of the soaking tank 11. The valve assembly 12 includes a chemical filling valve 121, a clean water filling valve 122, a soaking tank venting valve 123, and an aeration valve 124. The soaking unit 1 is used to soak the filter cartridges. The filter cartridges 4 are placed vertically in the soaking tank 11. The soaking tank 11 is a top-opening bucket shape, which facilitates the insertion and removal of the filter cartridges 4. Its length and width can be designed according to the size of the filter cartridges. Preferably, the top of the soaking tank 11 is hinged with a first side-flipping cover 13 that opens outward. The first side-flipping cover 13 of the soaking tank 11 flips to the left and completely covers the top surface of the soaking tank 21 to prevent foreign objects from falling in.

[0040] The filter cartridge rinsing device 2 includes a rinsing tank 21, a water pump assembly 22 installed outside the rinsing tank 21, and an inner rinsing nozzle 23, an outer rinsing nozzle 24, and a rotating drum 25 installed longitudinally parallel inside the rinsing tank 21. Preferably, a maintenance cover 27 is hinged to the rear top of the rinsing tank 21. More preferably, the maintenance cover 27 is a flip-top cover, with a positioning self-locking mechanism 28 on one side that is connected to the support of the rinsing tank. The maintenance cover 27 must completely cover the top surface of the rinsing tank 21, and its inner side may be equipped with a splash-proof baffle. The positioning self-locking mechanism 28 is a flip-top limiter, which can be a door or window limiter, to achieve repeated self-locking in the absence of electrical, spring, or air pressure. After the maintenance cover 27 is opened, it can remain open as needed for convenient maintenance.
[0041] The filter element 4 is mounted longitudinally and nearly horizontally on the inner flushing nozzle 23. The inner flushing nozzle 23 and the outer flushing nozzle 24 are arranged vertically and are respectively connected to the water pump assembly 22. Preferably, the water pump assembly 22 includes a water pump motor 221, a high-pressure water pump 222, and an inlet hose 223 connected in sequence. The inlet hose 223 is connected to the inner flushing nozzle 23 and the outer flushing nozzle 24. After the water pump motor 221 is energized, it is driven to rotate at high speed through a coupling. The high-pressure water pump 222 pressurizes the incoming water to 2MPa and 2L / min, and delivers it to the inner flushing nozzle 23 and the outer flushing nozzle 24 through the inlet hose 223, thereby achieving the purpose of high-pressure flushing of the filter element.
[0042] Preferably, one end of the inner flushing nozzle 23 is fixedly installed on the rear inner wall of the flushing tank 21, and an inner flushing nozzle 231 is provided on its pipe wall; one end of the outer flushing nozzle 24 is fixedly installed on the rear inner wall of the flushing tank 21, and an outer flushing nozzle 241 is provided on its pipe wall facing the inner flushing nozzle. The inner flushing nozzle 23 is used to flush the inner wall of the filter element 4, and the outer flushing nozzle 24 is used to flush the outer wall of the filter element 4. The inner flushing nozzle 23 is located above the inside of the cleaning tank 21, and its structure is a round tube. It can be machined with irregular holes on one side or all four sides to spray fan-shaped liquid as nozzles. Since the filter element 4 is a hollow structure, the filter element 4 can be directly fitted onto the inner flushing nozzle 23 as a whole, thereby achieving the effect of the inner flushing nozzle 23 flushing the inside of the filter element 4. The external flushing nozzle 24 is located 150mm-250mm directly below the internal flushing nozzle 23. This distance must be greater than the radius of the filter element 4. The external flushing nozzle 24 is a round tube with a fan-shaped hole on one side that can spray out liquid as a nozzle. The sprayed liquid is sprayed onto the outside of the filter element 4, thereby achieving the function of flushing the outside of the filter element 4.
[0043] The rotating drums 25 are two sets of rotating rollers installed on both sides between the inner flushing nozzle 23 and the outer flushing nozzle 24. The inner flushing nozzle 23, the outer flushing nozzle 24 and the rotating drums 25 are arranged in a diamond shape. The filter element 4 to be flushed is fitted on the inner flushing nozzle 23. Under the action of gravity, the outer wall of the filter element 4 abuts against the rotating drums 25 on both sides. The rotating drums 25 on both sides drive the filter element 4 to rotate by friction, so as to achieve full circumferential flushing of the inner and outer walls of the filter element 4. On the other hand, a brush can be set to clean the gaps on the outer wall of the filter element 4.
[0044] Preferably, the rotating roller 25 consists of a first rotating roller on the right and a second rotating roller on the left, or the two can be interchanged. The outer periphery of the first rotating roller is covered with an anti-slip rubber sleeve 251, and the outer periphery of the second rotating roller is covered with a soft brush 252.
[0045] Preferably, the two ends of the rotating drum 25 are respectively mounted on the front and rear inner walls of the rinsing tub 21 via rotating bases 29, and are connected to a speed-regulating motor to drive the two rotating drums 25 to rotate in the same direction. The speed-regulating motor can be fixed. The rotating base 29 is a bearing seat, which is installed on the front and rear walls inside the rinsing tub 21. Bearings and frame seals are installed inside it. The two ends of the first and second rotating drums are respectively inserted into the bearings and frame seals of the corresponding four sets of rotating bases 29 to achieve the purpose of axially fixing the two sets of rotating drums 25.
[0046] In this embodiment, the first and second rotating rollers of the rotating drum 25 rotate in the same direction, are powered by 24V DC, and have adjustable speeds. The 24V power supply is to avoid the risk of electric shock due to leakage, and the adjustable speed design is to adjust the rotation speed of the filter element to achieve the best rinsing effect. In this embodiment, the first rotating roller on the right is wrapped with a high-friction anti-slip rubber sleeve 251 to increase the friction with the filter element; the second rotating roller on the left is wrapped with a soft brush 252 to brush off larger lumps and flocculent matter when in contact with the filter element. After the filter element 4 is fitted onto the inner rinsing nozzle 23, due to gravity, the lower sides of the filter element 4 will fall onto the first and second rotating rollers on both sides. At this time, the filter element 4 will rotate with the rotation of the first rotating roller, and the soft brush 252 on the second rotating roller will rotate to achieve the effect of brushing off lumps and flocculent matter on the outside of the filter element 4.
[0047] The front side wall of the flushing bucket 21 is provided with a filter element loading port 26 corresponding to the axial direction of the inner flushing nozzle 23. The filter element 4 is sleeved on the inner flushing nozzle 23 from the front side of the flushing bucket 21, which is convenient for installation and removal. Preferably, a sluice gate 261 is vertically installed at the filter element loading port 26. The sluice gate 261 is located on the front side wall of the flushing bucket 21. When the sluice gate 261 is lifted upward and movable to the top door jamb, it is blocked. At this time, the sluice gate 261 can be flipped backward and placed flat above the maintenance cover plate 27. At this time, the filter element 4 can be horizontally placed into and taken out of the flushing bucket 21 through the filter element loading port 26 vacated by the sluice gate 261.
[0048] The drying unit 3 includes a drying bucket 31 and a drying pipe rack 32 installed at the inner bottom of the drying bucket 31. The drying pipe rack is connected with a drying air inlet valve 33. The drying air inlet valve 33 can be connected with the valve assembly of the soaking unit 1, which is convenient for users to operate and more beautiful. The air supply in the drying bucket 31 is realized by opening or closing the valve. The drying bucket 31 is used to place the filter element 4 after flushing and provide protection for the filter element 4 after flushing, protecting the filter element 4 from being knocked and polluted. The drying pipe rack 32 can be welded into a "卌" shape with square stainless steel pipes and is connected with the drying air inlet valve 33 through stainless steel pipelines. The top of the drying pipe rack 32 is provided with air outlet holes with a diameter of about 2 mm, so as to provide drying output of drying gas for the filter element 4.
[0049] Preferably, the top of the drying bucket 31 is hinged with a second side-turning cover plate that opens outward. The second side-turning cover plate is a right turning cover plate symmetrical to the left turning cover of the first side-turning cover plate 13 of the soaking bucket 11, which prevents foreign objects from falling in, is convenient for the placement and removal of the filter element 4, and does not conflict with the filter element flushing device 2.
[0050] The utility model can solve the problems of the ordinary large-throughput filter element cleaning machine, such as the complexity of the equipment, large floor area, low cleaning efficiency, etc. caused by using two sets of devices for soaking and cleaning, and reduce the cost of filter element regeneration.
[0051] The specific embodiments in the utility model are only explanations of the utility model, and they are not limitations of the utility model.
