[0032] like Figures 1 to 5 As shown, the present invention provides an integrated filter cleaning device, which includes a soaking unit 1, a rinsing unit 2 and a drying unit 3 installed side by side. The soaking unit 1 is installed on the left side of the rinsing unit 2 and the drying unit 3 is installed on the right side of the rinsing unit 2.

[0033] 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 element 4. The filter element 4 is 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 element 4. Its length and width can be designed according to the size of the filter element. 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. The left-flipping design facilitates the insertion and removal of the filter element 4 without interfering with the rinsing unit 2 in the middle.

[0034] One end of the chemical dosing valve 121 is connected to the soaking tank 11, and the other end is connected to the user's chemical supply. The required amount of chemical is added by opening or closing the chemical dosing valve 121. One end of the clean water dosing valve 122 is connected to the inside of the soaking tank 11, and the other end is connected to the user's clean water supply. The required amount of clean water is added by opening or closing the clean water dosing valve 121. One end of the soaking tank vent valve 123 is connected to the bottom of the soaking tank 11, and the other end is connected to the user's waste liquid discharge pipeline. The liquid inside the soaking tank 11 is emptied by opening the soaking tank vent valve 123. One end of the aeration valve 124 is connected to the bottom of the soaking tank 11, and the other end is connected to the user's compressed air supply. The aeration valve 124 aerates and agitates the chemical solution inside the soaking tank 11 by opening or closing the aeration valve 124. The purpose is to ensure that the chemical is always fully dissolved and that it fully enters the gaps of the filter element 4.

[0035] The rinsing unit 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 self-locking positioning 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 self-locking positioning mechanism 28 is a flip-top limiter, which can repeatedly self-lock even without electrical, spring, or air pressure. After the maintenance cover 27 is opened, it can remain open as needed for convenient maintenance.

[0036] 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.

[0037] 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.

[0038] like Figure 5 As shown, the rotating drums 25 are two symmetrical sets rotatably 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.

[0039] Preferably, the two sets of rotating rollers 25 are a first rotating roller on the right and a second rotating roller on the left, or they 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.

[0040] 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.

[0041] In the embodiment, the first rotary drum and the second rotary drum of the rotary drum 25 rotate in the same direction, and are powered by 24V DC with adjustable speed. The 24V power supply is to avoid the risk of electric shock injury, and the adjustable speed design is to adjust the rotation speed of the filter element to achieve the best flushing effect. In the embodiment, the outer part of the first rotary drum on the right side is wrapped with a non-slip rubber sleeve 251 with high friction, and its purpose is to increase the friction with the filter element; the outer part of the second rotary drum on the left side is wrapped with a soft brush 252, and its purpose is to brush off larger lumps and flocs when contacting the filter element. After the filter element 4 is sleeved on the inner flushing nozzle 23, due to the action of gravity, the lower sides of both sides of the filter element 4 will fall on the first rotary drum and the second rotary drum on both sides. At this time, the filter element 4 will rotate with the rotation of the first rotary drum, and at the same time, the soft brush 252 on the second rotary drum will rotate to achieve the effect of brushing off the lumps and flocs outside the filter element 4.

[0042] A filter element loading port 26 axially corresponding to the inner flushing nozzle 23 is provided on the front side wall of the flushing bucket 21. 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 gate plate 261 is vertically installed at the filter element loading port 26. The gate plate 261 is located on the front side wall of the flushing bucket 21. The gate plate 261 can be lifted upward and blocked when reaching the top door jamb. At this time, the gate plate 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 gate plate 261.

[0043] 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 holes with a diameter of about 2 mm to facilitate the drying output of providing drying gas for the filter element 4.

[0044] Preferably, a second side-turning cover plate hinged to the top of the drying bucket 31 and opening outward is provided. The second side-turning cover plate is a right turning cover plate symmetric to the left turning cover of the first side-turning cover plate 13 of the soaking bucket 11, which can prevent foreign objects from falling in, facilitate the putting in and taking out of the filter element 4, and does not conflict with the flushing unit 2 at the same time.

[0045] This invention can solve the problems of complex equipment, large footprint, and low cleaning efficiency caused by the use of two separate devices for soaking and cleaning in ordinary high-flow filter cleaning machines, thereby reducing the cost of filter regeneration.

[0046] The specific embodiments described herein are merely illustrative of the invention and are not intended to limit it. Those skilled in the art can make modifications to these embodiments without contributing any inventive step after reading this specification, but such modifications are protected by patent law as long as they fall within the scope of the claims of this invention.
