[0040] The filter element fixing unit 3 includes a gear plate 31 and a filter element fixing frame 32 fixed to the gear plate 31. The filter element fixing frame 32 is a cylindrical structure welded with steel pipes, which is made by welding vertical steel pipes and annular steel pipes. The filter element is embedded in the filter element fixing frame 32. Preferably, there are six gear plates 31, which are arranged in a ring, and the edges of the six gear plates 31 are meshed in sequence.

[0041] The transmission unit 4 includes a first motor 41, a reducer 42, a transmission shaft 43, and a helical gear 44 connected in sequence. The helical gear 44 meshes with the gear plate 31. The first motor 41 and the reducer 42 are located outside the housing 2. The transmission shaft 43 passes through the housing 2.

The cross-section of the impeller blades 56 is V-shaped. The impeller blades 56 are snapped onto the impeller paddles 54, thereby embedding the ultrasonic generator 55 into the accommodating cavity formed by the impeller blades 56 and the impeller paddles 54. The oscillating ultrasonic waves generated by the ultrasonic generator 55 enter the filter element through the ultrasonic hole, thereby realizing ultrasonic oscillation cleaning of the filter element.

[0043] It should be noted that the motor 51 rotates the output shaft 52, which in turn rotates the impeller blade 54. The impeller blade 54 rotates the ultrasonic generator 55 and the impeller blade 56 at a constant speed. The ultrasonic generator 55 generates uniform oscillating ultrasonic waves, thereby enabling ultrasonic cleaning of all six filter elements. The mechanical seal 45 and the mechanical seal base 53 prevent leakage of liquid from the housing along the output shaft 52, thereby improving the overall sealing performance.

[0044] The pipeline unit 6 includes a water inlet pipeline 61, an alkali liquid pipeline 62, an air intake pipeline 63, a high-pressure water pump 64, a second motor 65 and a guide plate 66. In order to facilitate independent control of each pipeline, ball valves, solenoid valves and one-way valves are installed in sequence at the inlets of the water inlet pipeline 61, the alkali liquid pipeline 62 and the air intake pipeline 63. The guide plate 66 includes a ring pipeline and a riser 661 connected to the ring pipeline. The number of the risers 661 is 6, which are evenly distributed on the ring pipeline. A fixing plate 662 is provided on the guide plate 66. The number of the fixing plates 662 is 6, and the fixing plates 662 are arranged on a straight line from the center of the guide plate 66 to the riser 661. The guide plate 66 is fixed to the bottom head by the fixing plate 662, thereby realizing the fixation of the filter element fixing frame 32 and the filter element.

[0045] The second motor 65 is connected to the high-pressure water pump 64. The water inlet pipe 61 and the alkali solution pipe 62 are merged into the main pipe and then connected to the solenoid valve and the high-pressure water pump 64. It passes through the shell 2 and is divided into a first branch and a second branch. The first branch is connected to the annular pipe of the guide plate 66, and the second branch is connected to the center of the guide plate 66; the air intake pipe passes through the shell 2 and is divided into a first branch and a second branch. The first branch is connected to the annular pipe of the guide plate 66, and the second branch is connected to the center of the guide plate 66.

[0046] The nozzle unit 7 includes a first nozzle 71 and a second nozzle 72. The first nozzle 71 is installed at the center of the guide plate 66, and the second nozzle 72 is installed in the vertical pipe 661 of the guide plate 66. The first nozzle 71 and the second nozzle 72 are both rod-shaped structures with circumferentially distributed nozzles of the rod-shaped structure. The nozzles are designed into a V-shaped structure so that the sprayed liquid or gas is distributed in a fan-shaped manner, thereby increasing the effective area on the filter element and thus improving the cleaning or drying effect; a bearing 74 is circumferentially sleeved on the vertical pipe 661, and the bearing 74 passes upward through the middle of the gear plate 31. The second nozzle 72 is embedded in the inner ring of the bearing 74. That is, the guide plate 66 is located at the bottom of the gear plate 31, and the second nozzle 72 passes through the inner ring of the bearing 74 and is inserted into the vertical pipe 661 of the guide plate 66, thereby achieving the fixation of the second nozzle 72. Moreover, when the gear plate 31 drives the filter element to rotate, the second nozzle 72 does not rotate, and the filter element is embedded in the second nozzle 72, thereby achieving comprehensive cleaning or drying of the inner wall of the filter element. The bearing 74 has a conical structure, that is, the upper diameter of the bearing 74 is smaller than the lower diameter. The upper part of the outer ring of the bearing 74 is embedded in the center hole of the gear plate 31, and the lower part of the inner ring of the bearing 74 is sleeved on the circumference of the standpipe 661, thereby improving the stability of the second nozzle 72.

[0047] It should be noted that the first branch is connected to the center of the annular pipeline of the guide plate 66, that is, connected to the first nozzle 71. The gas or liquid enters the bottom of the first nozzle 71 through the first branch, and is sprayed from the bottom to the top through the nozzle to achieve cleaning or drying of the periphery of the filter element; the second branch is connected to the annular pipeline of the guide plate 66, and enters the 6 second nozzles 72 through the 6 vertical pipes 661 respectively, and is sprayed from the bottom to the top through the nozzle to achieve cleaning or drying of the inner wall of the filter element.

[0048] A boost pipe 8 is installed at the bottom of the first nozzle 71 and the second nozzle 72.

The number of the second oblique tube 82, the third oblique tube 83 and the U-shaped tube 84 is at least 2. The liquid enters the first inclined tube 81 from the bottom, and moves upward along the first inclined tube 81 into the second inclined tube 82. Due to the resistance of the second inclined tube 82, part of the liquid continues to flow upward along the second inclined tube 82, and the other part of the liquid flows downward along the second inclined tube 82 due to the resistance, enters the U-shaped pipe 84, and enters the first inclined tube 81 again through the U-shaped pipe 84, thereby increasing the liquid in the first inclined tube 81. Similarly, the U-shaped pipe 84 connected to the third inclined tube 83 pressurizes the second inclined tube 82. By setting the boosting pipe 8, the fluid is continuously pressurized, so that the fluid can flow upward along the rod-shaped first nozzle 71 and the second nozzle 72, and reach the top nozzles of the first nozzle 71 and the second nozzle 72 to clean or dry the top of the filter element.

[0049] Example 2

[0050] The present invention provides a filter element cleaning method, using the device described in Example 1, the method comprising the following steps:

[0051] S1: Install the filter element into the filter element fixing unit 3;

[0052] Specifically, the telescopic rod of the main push cylinder 12 is controlled to be in a retracted state. At this time, the cylinder 21 is in a horizontal state. The upper cover 22 is opened, and the six filter elements are sequentially installed into the filter element fixing frame 32. The second nozzle 72 is embedded in the filter element. The upper cover 22 is closed, and the telescopic rod of the main push cylinder 12 is controlled to extend. The telescopic rod pushes the cylinder 21, so that the cylinder 21 is in a vertical state.

[0053] S2: Alkaline solution and water are introduced into the piping unit 6 in sequence, and then the ultrasonic cleaning unit 5 is turned on to soak and clean the filter element with ultrasonic vibration;

[0054] Alkali liquid is introduced into the alkali liquid pipeline 62, the alkali liquid pipeline 62 is closed, and clean water is introduced into the water inlet pipeline 61 to dilute the alkali liquid. The alkali liquid and clean water enter the first nozzle 71 and the second nozzle 72 through the guide plate 66 and finally enter the housing. When the water level reaches the monitoring height of the water level switch, the water inlet pipeline 61 is closed, and the diluted alkali liquid soaks the filter element; when the water inlet pipeline 61 is closed, the motor 51 and the ultrasonic generator 55 are turned on, the motor 51 drives the output shaft 52 to rotate, the output shaft 52 drives the impeller blade 54 to rotate, the impeller blade 54 drives the ultrasonic generator 55 and the impeller blade to rotate, the ultrasonic generator 55 emits ultrasonic waves, and performs ultrasonic vibration cleaning on the filter element. The ultrasonic vibration cleaning and soaking cleaning are performed simultaneously;

[0055] S3: Turn on the transmission unit 4, which drives the filter element to rotate. Water is introduced into the pipe unit 6 to flush the filter element. Compressed air is introduced into the pipe unit 6 to dry the filter element.

[0056] The first motor 41 drives the reducer 42, which drives the transmission shaft 43 to rotate. The transmission shaft 43 drives the helical gear 44 to rotate. The helical gear 44 drives the gear plate 31 to rotate. The gear plate 31 drives the filter element holder 32 and the filter element fixed thereon to rotate. At the same time, clean water is introduced into the water inlet pipe 61. The clean water enters the first nozzle 71 and the second nozzle 72 through the guide plate 66, respectively rinsing the inner wall and outer periphery of the filter element. After rinsing, compressed air is introduced into the air inlet pipe 63. The compressed air enters the first nozzle 71 and the second nozzle 72 through the guide plate 66, respectively drying the inner wall and outer periphery of the filter element. The telescopic rod of the main push cylinder 12 is controlled to be in a retracted state so that the cylinder 21 is in a horizontal state. The upper cover 22 is opened and the six filter elements are removed. Preferably, before removing the filter element, a gravity sensor detects the weight after cleaning. By calculating the difference between the weight after cleaning and the weight of the device itself, if it exceeds a preset value, it indicates that the filter cleaning is insufficient and the above steps need to be repeated for cleaning.
