A vertical pipe 505 is rotatably connected to the inner wall of the filter cartridge 2. The top of the vertical pipe 505 passes through the filter cartridge 2 and is fixedly connected to the bottom end of another bevel gear 501. The surface of the vertical pipe 505 is rotatably connected to horizontal pipes 506 distributed in equal rows. Two cleaning pipes 507 are fixedly connected to the surface of the horizontal pipe 506. A reciprocating component 508 is arranged on the surface of the vertical pipe 505.

[0025] The inner wall of the filter plate 4 is fixedly connected to the surface of the ring 503, and three groups of annular through holes 504 are provided, which are respectively located above the corresponding filter plates 4. The apertures of the three filter plates 4 decrease from top to bottom, the top of the filter cartridge 2 is provided with a feed port, and the lower end of the surface of the shunt pipe 3 is provided with multiple outlets. When filtering the buffer solution, the buffer solution is poured in from the feed port, flows out through the shunt pipe 3, and is filtered through the three filter plates 4 in turn. After the filtration is completed, it can be collected through the discharge pipe at the bottom of the filter cartridge 2.

[0026] During cleaning, the top of the vertical pipe 505 is connected to the external water pipe through the bearing, and the number of the horizontal pipes 506 is set to three, and the position of the horizontal pipes 506 corresponds to the position of the filter plate 4. After the connection, the cleaning liquid enters the vertical pipe 505 and is sprayed out through the horizontal pipe 506 and the cleaning pipe 507 to clean the filter plate 4. At this time, the motor 502 is started through the controller. The vertical pipe 505 is driven to rotate through the bevel gear 501, so that the horizontal pipe 506 drives the cleaning pipe 507 to rotate 360 ​​degrees on the inner side of the filter plate 4 to clean the filter plate 4.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the reciprocating assembly 508 includes a moving ring 5081 slidably connected to the surface of the vertical tube 505, the lower end of the surface of the moving ring 5081 is fixedly connected to a connecting rod 5082, the surface of the connecting rod 5082 is hinged with round rods 5083 distributed in equal rows, the other end of the round rod 5083 is fixedly connected to the surface of the corresponding horizontal tube 506, the upper end of the surface of the moving ring 5081 is rotatably connected to a connecting plate 5084, a spring 5086 is fixedly connected between the bottom end of the connecting plate 5084 and the top end of the filter cartridge 2, the output shaft of the motor 502 is fixedly connected to a cam 5085, and the surface of the cam 5085 fits with the top end of the connecting plate 5084.

[0028] The cleaning pipe 507 is tilted in the initial state. During cleaning, when the horizontal pipe 506 rotates, the round rod 5083 and the connecting rod 5082 are driven to rotate synchronously, thereby driving the moving ring 5081 to rotate synchronously.

[0029] When the output shaft of the motor 502 rotates, it will drive the cam 5085 to rotate synchronously. When the highest point of the cam 5085 contacts the top of the connecting plate 5084, the connecting plate 5084 is pushed to move downward, and the spring 5086 is compressed. When the lowest point of the cam 5085 contacts the top of the connecting plate 5084, the connecting plate 5084 is reset under the action of the spring 5086. Therefore, under the action of the cam 5085 and the spring 5086, the connecting plate 5084 drives the moving ring 5081 to move back and forth up and down, thereby driving the connecting rod 5082 to move back and forth up and down, and under the action of the round rod 5083, when the connecting rod 5082 moves up and down, it will drive the cross tube 506 to rotate back and forth, so that the cross tube 506 drives the cleaning tube 507 to rotate while rotating back and forth up and down to clean the filter plate 4, so that the cleaning angle changes continuously.

[0030] like Figure 2 and Figure 3 As shown, a plurality of protective rings 509 are slidably connected to the surface of the circular ring 503, an electric push rod 5092 is fixedly connected to the top of the filter cartridge 2, the bottom end of the electric push rod 5092 penetrates the filter cartridge 2 and is fixedly connected to a pull rod 5091, and the inner walls of the plurality of protective rings 509 are fixedly connected to the surface of the pull rod 5091. An angle is formed between the top of the protective ring 509 and the horizontal plane.

[0031] The number of protective rings 509 is set to three, and the bottom end of the protective ring 509 fits with the top end of the corresponding filter plate 4, the inner wall of the protective ring 509 fits with the surface of the ring 503, and the positions of the three protective rings 509 correspond to the positions of the three groups of through holes 504. When the buffer solution is filtered, the three protective rings 509 will seal the three groups of through holes 504.

[0032] When the filter plate 4 is flushed, the electric push rod 5092 is started to drive the pull rod 5091 to move upward, thereby driving the three protective rings 509 to move upward, thereby releasing the blockage of the through hole 504.

[0033] like Figure 5 As shown, a sealing bearing 5087 is provided at the connection between the surface of the horizontal tube 506 and the vertical tube 505. The outer edge of the sealing bearing 5087 is fixedly connected to the inner wall of the vertical tube 505, and the inner edge of the sealing bearing 5087 is fixedly connected to the surface of the horizontal tube 506.

[0034] like Figure 4 As shown, the top of the filter cartridge 2 is fixedly connected to a limiting rod 5088, and the top of the limiting rod 5088 sequentially penetrates the spring 5086 and the connecting plate 5084. The surface of the limiting rod 5088 is slidably connected to the inner wall of the connecting plate 5084.

[0035] like Figure 4 As shown, an annular groove 5089 is provided on the upper end of the surface of the moving ring 5081, and one end of the connecting plate 5084 is rotatably connected to the inner wall of the annular groove 5089. When the moving ring 5081 rotates, the other end of the connecting plate 5084 rotates in the annular groove 5089.

[0036] When the utility model is in use and cleaning, the electric push rod 5092 is started to make the pull rod 5091 pull the protective ring 509 to move upward, thereby releasing the blockage of the through hole 504, and connecting the top of the vertical pipe 505 to the external water pipe through the bearing, so that the cleaning liquid enters the vertical pipe 505 and is sprayed out through the horizontal pipe 506 and the cleaning pipe 507 to clean the filter plate 4. At this time, the motor 502 is started by the controller. The vertical tube 505 is driven to rotate through the bevel gear 501, so that the horizontal tube 506 drives the cleaning tube 507 to rotate 360 ​​degrees on the inner side of the filter plate 4 to clean the filter plate 4. At the same time, when the output shaft of the motor 502 rotates, it will drive the cam 5085 to rotate synchronously. Under the action of the cam 5085 and the spring 5086, the connecting plate 5084 drives the moving ring 5081 to move back and forth up and down, thereby driving the connecting rod 5082 to move back and forth up and down. Under the action of the round rod 5083, when the connecting rod 5082 moves up and down, it will drive the horizontal tube 506 to rotate back and forth, so that the horizontal tube 506 drives the cleaning tube 507 to rotate while rotating back and forth up and down to clean the filter plate 4, so that the cleaning angle is constantly changing, and the cleaned solution is discharged through the discharge pipe at the bottom of the filter cylinder 2.

[0037] It should be noted that the motor 502, electric push rod 5092, etc. in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the motor 502 and the electric push rod 5092 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
