[0027] Referring to Figure 3 , Figure 4 , the filter assembly 7 comprises a positioning ring 71, the inner wall of the positioning ring 71 is provided with a stainless steel mesh cover 72, the top surface of the positioning ring 71 is provided with a plurality of positioning holes 73, the inner cavity of each positioning hole 73 is inserted with a positioning screw 74, the bottom end of the positioning screw 74 is rotatably connected with the top surface of the support ring 6;

[0028] Through the positioning ring 71 in the filter assembly 7, the stainless steel mesh cover 72 can be installed and fixed, and the positioning screw 74 can be inserted and installed through the positioning hole 73, because the bottom end of the positioning screw 74 is rotatably connected with the top surface of the support ring 6, so by rotating the positioning screw 74, the positioning ring 71 can be fixed on the support ring 6, thereby improving the stability of the use of the stainless steel mesh cover 72, through the stainless steel mesh cover 72, the flowing material can be filtered, and the filtered dirt will be attached to the outer wall of the stainless steel mesh cover 72, thereby playing a role in intercepting dirt.

[0029] Referring to Figure 3 , Figure 4 , the filter assembly 7 further comprises a sealing rubber ring 75, which is arranged between the positioning ring 71 and the support ring 6, through the sealing rubber ring 75, the sealing effect between the positioning ring 71 and the support ring 6 after installation can be improved.

[0030] Referring to Figure 3 , Figure 4The filter assembly 7 also includes a retaining frame 76. There are two retaining frames 76, both of which are located inside the stainless steel mesh cover 72. This can improve the structural strength of the stainless steel mesh cover 72 and thus extend its service life.

[0031] See Figure 3 - Figure 5 The cleaning component 8 includes a mounting plate 81 disposed on one side of the bottom surface of the filter barrel 1. A motor 82 is disposed on the side wall of the mounting plate 81. The output shaft of the motor 82 passes through the bottom surface of the filter barrel 1 and is connected to the filter barrel 1 through a shaft seal 85. A U-shaped frame 83 is disposed on the output shaft of the motor 82 and located in the inner cavity of the filter barrel 1. Rubber scraper strips 84 are disposed on both sides of the inner cavity of the U-shaped frame 83.

[0032] The motor 82 in the cleaning assembly 8 can be fixed to the bottom surface of the filter barrel 1 via the mounting plate 81, and can also drive the U-shaped frame 83 to rotate via the output shaft. Since rubber scrapers 84 are provided on both sides of the inner cavity of the U-shaped frame 83, when the U-shaped frame 83 rotates, the rubber scrapers 84 can clean the dirt attached to the outer wall of the stainless steel mesh cover 72, thereby improving the cleaning effect of the stainless steel mesh cover 72. The shaft seal 85 can ensure the rotation of the output shaft of the motor 82 and prevent material leakage from this point.

[0033] See Figure 3 , Figure 5 and Figure 6 The two outer side walls of the U-shaped frame 83 are provided with multiple wheel frames 86, and the inner cavity of each wheel frame 86 is rotatably connected to a wheel 87.

[0035] See Figure 1 , Figure 2 The filter barrel 1 is provided with a fixing frame 11 on the outside in a symmetrical manner, which can be used to install and fix the filter barrel 1, thereby improving the stability of the filter barrel 1 in use.

[0036] When the material needs to be filtered, the liquid supply pipe is connected to the liquid inlet pipe 3, and then the liquid outlet pipe 4 is connected to the conveying pipe. The supporting ring 6 can be fixed in the inner cavity of the filter barrel 1 and can install and fix the filter assembly 7. When the liquid inlet pipe 3 delivers the material to the inner cavity of the filter barrel 1, the material passes through the filter assembly 7 and enters the inner cavity of the filter assembly 7, and then is discharged through the liquid outlet pipe 4 inserted in the filter assembly 7. Since the outer wall of the liquid outlet pipe 4 is provided with a plurality of through holes 5, the speed of the filtered material entering the liquid outlet pipe 4 can be improved. When the dirt attached to the outer wall of the filter assembly 7 needs to be cleaned, the material supply of the liquid inlet pipe 3 is closed first, then the external water pipe is connected through the liquid outlet pipe 4, and the valve 10 on the dirt discharge pipe 9 and the cleaning assembly 8 are opened. At this time, the water flowing back through the liquid outlet pipe 4 can preliminarily clean the outer wall of the filter assembly 7, and the dirt attached to the outer wall of the filter assembly 7 can be scraped off through the cleaning assembly 8, so that the cleaning effect and quality of the filter assembly 7 can be improved. The dirt cleaned can be discharged through the dirt discharge pipe 9. The whole process does not need to disassemble the equipment, reduces the cost of equipment maintenance, and improves the convenience of later equipment maintenance.

[0037] The positioning ring 71 in the filter assembly 7 can install and fix the stainless steel mesh cover 72, and can be inserted and installed through the positioning hole 73. Since the bottom end of the positioning screw 74 is rotationally connected to the top surface of the supporting ring 6, the positioning ring 71 can be fixed on the supporting ring 6 by rotating the positioning screw 74, so that the stability of the use of the stainless steel mesh cover 72 can be improved. The stainless steel mesh cover 72 can filter the material flowing through it, and the dirt filtered can be attached to the outer wall of the stainless steel mesh cover 72, so that the dirt can be intercepted. The sealing rubber ring 75 can improve the sealing effect between the positioning ring 71 and the supporting ring 6 after installation. The stable frame 76 can improve the structural strength of the stainless steel mesh cover 72, so that the service life of the stainless steel mesh cover 72 can be improved.

[0038] The motor 82 in the cleaning assembly 8 can be fixed on the bottom surface of the filter barrel 1 through the mounting plate 81, and can drive the U-shaped frame 83 to rotate through the output shaft. Since the inner cavities of the two side walls of the U-shaped frame 83 are provided with rubber scraping strips 84, when the U-shaped frame 83 rotates, the rubber scraping strips 84 can clean the dirt attached to the outer wall of the stainless steel mesh cover 72, so that the cleaning effect of the stainless steel mesh cover 72 can be improved. The shaft seal 85 can ensure the rotation of the output shaft of the motor 82 and prevent the material from leaking. The cooperation of the wheel frame 86 and the wheel 87 can keep the U-shaped frame 83 stable when rotating, so that the stability of the rubber scraping strips 84 when cleaning the stainless steel mesh cover 72 can be improved.

[0039] In summary, the device does not need to disassemble the equipment throughout the process, reduces the cost of equipment maintenance and improves the convenience of later equipment maintenance.

[0040] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.
