[0028] Referring to Figure 2 and Figure 3 , it is further obtained that the filtering assembly 5 has a supporting frame 6, a filtering outer frame 7 and a mounting plate 9, the supporting frame 6 is fixedly installed on the top end of the workbench 1 at a position close to one side, a mounting block is fixedly connected to the center position of one side of the filtering outer frame 7, and the filtering outer frame 7 is installed on the other side of the supporting frame 6 at a position close to the top through the mounting block and mounting bolts, a filtering inner frame 8 is fixedly installed on the top end of the filtering outer frame 7 at a center position, a filter screen frame 11 is arranged between the filtering inner frame 8 and the filtering outer frame 7, a material falling port that is adaptively matched with the filter screen frame 11 is formed through the upper and lower ends of the filtering outer frame 7, and the mounting plate 9 is fixedly installed on the top end of the workbench 1 at a position close to the back.

[0029] A anti-clogging motor 10 is installed on the top end of the mounting plate 9, a transmission rod is fixedly connected to the bottom end of the drive shaft of the anti-clogging motor 10, the transmission rod penetrates through the top end of the filtering inner frame 8, connecting plates 12 are slidably installed on the top surface of the filtering inner frame 8 at positions close to both sides, one end of each of the two connecting plates 12 that are close to each other is fixedly connected to the transmission rod, cleaning scrapers 14 are movably installed on one end of each of the two connecting plates 12 that are away from each other through movable rods 13, the inner sides of the two cleaning scrapers 14 are attached to the outer circle of the filter screen frame 11, an installation groove is arranged in the connecting plate 12, a tension spring 15 is arranged in the installation groove, one end of the tension spring 15 is fixedly connected to the movable rod 13, and the other end of the tension spring 15 is fixedly connected to the inner wall of the connecting plate 12, the mounting plate 9 is arranged in an "L" shape, the center points of the anti-clogging motor 10, the filtering inner frame 8 and the filtering outer frame 7 are on the same vertical line.

[0030] Specifically, in the filtering process, the conductive silver paste can be poured into the filter outer frame 7 so as to filter the conductive silver paste through the filter screen frame 11. During the filtering process, impurities that do not meet the standard will stay in the filter outer frame 7. The filter screen frame 11 is in a cylindrical shape and is installed on the filter outer frame 7. The filter screen frame 11 does not bear the weight, thereby reducing the probability of deformation under pressure and prolonging the service life of the filter screen frame 11. During the filtering process of the filter screen frame 11, the anti-blocking motor 10 can be started to drive the connecting plate 12 to rotate. The connecting plate 12 can drive the cleaning scraper 14 to rotate and adhere to the outer circle of the filter screen frame 11, so as to clean the outer circle of the filter screen frame 11. Thus, the probability of large impurities being accumulated and blocked in the filter screen frame 11 can be reduced, and the filtering of the filter screen frame 11 is not affected. In addition, the conductive silver paste at different heights can be filtered through the cylindrical filter screen frame 11. The conductive silver paste that is not at the bottom is filtered first, thereby improving the filtering efficiency. The filter screen frame 11 is in the middle of the filter outer frame 7. The force generated by the continuous stirring and liquid flow can drive the impurities to move, so as to avoid the impurities from being directly deposited and blocked downward, thereby further preventing the blockage.

[0031] Embodiment Two

[0032] Reference Figure 2 Figure 4 On the basis of Embodiment One, it is further obtained that the transmission rod is rotatably connected with the filter inner frame 8, and the end of the transmission rod extending into the filter inner frame 8 is fixedly connected with the cleaning rod 16 at the positions close to the two sides. The cleaning brush 17 is installed on the cleaning rod 16 away from the transmission rod through the elastic member 18. The end of the cleaning brush 17 away from the cleaning rod 16 is in abutment with the inner circle of the filter screen frame 11. The filter screen frame 11 is in a cylindrical shape. The bottom surface of the filter screen frame 11 is in abutment with the top surface of the filter outer frame 7. The opening rate of the filter screen frame 11 is not less than 90% of the total area. The filter outer frame 7 is provided with the discharge valve opening 20 at the position close to the lower part of the side away from the support frame 6. The sealing plate is arranged between the filter outer frame 7 and the discharge valve opening 20. The electric telescopic rod 19 is installed on the side of the top end of the filter outer frame 7 close to the discharge valve opening 20. The push rod of the electric telescopic rod 19 is fixedly connected with the top end of the sealing plate. The adjusting groove matched with the sealing plate is arranged in the filter outer frame 7. The handle is arranged at the central position of the front end of the recovery box 3. The liquid discharge valve pipe is arranged at the position close to the side of the rear end of the recovery box 3.

[0033] Specifically, when filtering, the driving shaft of the anti-blocking motor 10 rotates, which drives the transmission rod to rotate, thereby driving the cleaning rod 16 installed on the transmission rod to rotate. Through the rotation of the cleaning rod 16, the cleaning brush 17 can rotate and adhere to the inner circle of the filter screen frame 11, so as to clean the filter holes of the filter screen frame 11 from the inside, further reducing the probability of blockage of the filter screen frame 11. During use, the external sealing cover can be used to seal the top of the filter outer frame 7. Then, under the condition that the conductive silver paste continuously fills the filter outer frame 7, the stirring of the liquid by the cleaning rod 16 and the cleaning brush 17 can drive the conductive silver paste to rotate around the outer wall of the filter screen frame 11, and the filtering is not static, so as to improve the filtering effect.

[0034] In actual operation, during the filtering process, the conductive silver paste can be poured into the filter outer frame 7 to be filtered by the filter screen frame 11. During the filtering process, impurities that do not meet the standard will remain in the filter outer frame 7. The filter screen frame 11 is cylindrically arranged, and the filter screen frame 11 is installed on the filter outer frame 7, so that the filter screen frame 11 does not bear the weight, thereby reducing the probability of deformation of the filter screen frame 11 under pressure, improving the service life of the filter screen frame 11, and enabling the filter screen frame 11 to be cleaned by rotating the connecting plate 12 and the cleaning scraper 14.

[0035] Thus, the probability of large impurities accumulating and blocking at the filter screen frame 11 can be reduced, avoiding a large impact on the filtering of the filter screen frame 11. At the same time, conductive silver paste at different heights can be filtered by the cylindrical filter screen frame 11. The conductive silver paste not at the bottom is filtered first, which can improve the filtering efficiency. The filter screen frame 11 is in the middle of the filter outer frame 7, and the force generated by the continuous stirring and liquid flow can drive the impurities to move, avoiding direct downward sedimentation and blockage, and further preventing blockage.

[0036] When filtering, the driving shaft of the anti-blocking motor 10 rotates, which drives the transmission rod to rotate, thereby driving the cleaning rod 16 installed on the transmission rod to rotate. Through the rotation of the cleaning rod 16, the cleaning brush 17 can rotate and adhere to the inner circle of the filter screen frame 11, so as to clean the filter holes of the filter screen frame 11 from the inside, further reducing the probability of blockage of the filter screen frame 11.

[0037] And under the condition that the conductive silver paste continuously fills the filter outer frame 7, the stirring of the liquid by the cleaning rod 16 and the cleaning brush 17 can drive the conductive silver paste to rotate around the outer wall of the filter screen frame 11, and the filtering is not static, so as to improve the filtering effect.

[0038] And after all the filtering, by pulling down the anti-off lock 4, the locking of the recycling box 3 can be released, and then the recycling box 3 can be pulled out to process the collected conductive silver paste, and a pipeline can be connected to the recycling box 3 to directly transfer the collected conductive silver paste, and when the filter screen frame 11 and the filter outer frame 7 need to be cleaned, the electric telescopic rod 19 can be started to drive the filter outer frame 7 and the sealing plate at the discharge valve port 20 to rise, and then the impurities can be washed out from the discharge valve port 20.

[0039] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
