The inner side surface of the filter body 2 and the filter hole groups two 43 are provided with a gap, and the angle of the arc surface of the filter arc plate 41 is 60 degrees. The arc surface of the filter arc plate 41 is designed to facilitate the impurities in the resin mucilage far from the one end of the rotating shaft 53 to be scraped to the edge of the filter arc plate 41, and the impurities fall into the gap between the filter arc plate 41 and the filter body 2 through the arc surface design of the filter arc plate 41. The opening diameter of the impurity filtering groove 55 is larger than that of the resin flow-through groove 56, the inner side surface of the filter body 2 is fixedly connected with a spring telescopic block 511, the telescopic end of the spring telescopic block 511 is provided with an arc surface, the telescopic end of the spring telescopic block 511 is located on the displacement track of the stirring rod 54, and the one end of the stirring rod 54 contacting the spring telescopic block 511 is provided with an arc surface. In order to prevent the resin flow-through groove 56 from being blocked by too many impurities during the filtering process and losing the function, the telescopic end of the spring telescopic block 511 is periodically impacted during the periodic rotation of the stirring rod 54, and the vibration force generated during the impact is used to vibrate and shake off the too many impurities in the resin flow-through groove 56, thereby improving the flow-through efficiency of the resin flow-through groove 56.The suction and pressure suction equipment 6 comprises a belt shaft 61, one end of the belt shaft 61 is fixedly sleeved on the outer surface of the rotating shaft 53, a belt 62 is arranged on the circumferential surface of the belt shaft 61, the belt shaft 61 is drivingly connected with a belt shaft 63 through the belt 62, one end of the belt shaft 63 penetrates through a gear pump box 64 and is in rotationally connected with the gear pump box 64, the belt shaft 63 penetrates through the gear pump box 64 at one end and is fixedly connected with a driving gear 65, a driven gear 66 is rotationally connected with the inner wall of the gear pump box 64, a suction pipe 67 is fixedly connected with one side of the gear pump box 64, and a discharge pipe 68 is fixedly connected with the other side of the gear pump box 64. Since the resin mucilage has high viscosity and poor flowability, the suction and pressure suction equipment 6 is designed to increase suction and improve the flowability of the resin mucilage, thereby improving the filtration rate and the discharging rate of the resin mucilage and improving the working efficiency of the whole equipment. The bottom of the gear pump box 64 is fixedly connected with the inner wall bottom of the filter body 2, and the driving gear 65 and the driven gear 66 are in meshing with each other. Such a design ensures stable transmission of the equipment. One end of the suction pipe 67 is fixedly connected with a through pipe 69, the side surface of the through pipe 69 is fixedly connected with a suction branch pipe 610 and a suction branch pipe 611, the ends of the suction branch pipe 610 and the suction branch pipe 611 away from the through pipe 69 are fixedly connected with one suction hole inside the suction hole group 45 respectively, and the ends of the suction branch pipe 610 and the suction branch pipe 611 close to the suction hole group 45 are fixedly connected with a leak plate 612, and the top of the leak plate 612 is fixedly connected with the bottom of the receiving circular table 44. The design of the suction branch pipe 610 and the suction branch pipe 611 balances the suction force on both sides below the filter arc plate 41, the design of the leak plate 612 avoids strong suction force generated by the suction branch pipe 610 and the suction branch pipe 611, so that the resin pure liquid inside the receiving circular table 44 flows to the inside of the filter body 2 through the gap possibly generated when the suction branch pipe 610, the suction branch pipe 611 and the receiving circular table 44 are installed, thereby causing damage to the electronic components below.

[0031] In use, when the resin mucilage needs to be filtered and impurities removed, the staff can pour the resin mucilage into the inside of the filter body 2 by rotating the cover plate 3, and then reverse the cover plate 3 to close the filter body 2. At this time, the inside of the filter body 2 becomes a vacuum state;

[0032] Subsequently, the operator starts the motor 52 to drive the rotating shaft 53 to rotate, which drives the stirring rod 54 to rotate, and the stirring rod 54 rotates to evenly spread the resin mucilage on the surface of the filter arc plate 41. The filter hole group one 42 on the surface of the filter arc plate 41 filters the impurities, and the filtered resin mucilage penetrates into the receiving circular table 44 through the filter hole group one 42. At the same time, the stirring rod 54 continues to rotate, and the impurities near the end of the rotating shaft 53 are collected through the impurity filtering groove 55, and the resin pure liquid contained in the impurities is discharged to the surface of the filter hole group one 42 through the resin flow-through groove 56 for continuous filtering. In order to prevent the resin flow-through groove 56 from being blocked by too many impurities during the filtering process and losing its function, the periodic impact spring expansion block 511 is impacted on the expansion end during the periodic rotation of the stirring rod 54, and the vibration force generated by the impact shakes off the impurities in the resin flow-through groove 56, thereby improving the flow-through efficiency of the resin flow-through groove 56. When the filtering process is completed, the dust collector 58 can be started to absorb and process the impurities remaining in the stirring rod 54 through the connecting pipe 57. The impurities in the resin mucilage away from the end of the rotating shaft 53 are scraped to the edge of the filter arc plate 41, and through the arc surface design of the filter arc plate 41, they fall into the gap between the filter arc plate 41 and the filter body 2. The excess resin mucilage flows into the inside of the receiving circular table 44 through the filter hole group two 43 on the arc surface of the filter arc plate 41 for collection. Through the continuous rotation of the stirring rod 54, not only the resin impurities with viscosity are quickly spread, but also the pushing force generated by the continuous rotation of the stirring rod 54 combines with the arc surface design of the filter arc plate 41 to gather the impurities contained in the resin mucilage to the gap between the filter arc plate 41 and the filter body 2, thereby avoiding the blockage of the surface of the filter hole group one 42 caused by too many impurities contained in the resin mucilage, which affects the filtering rate and effect.

[0033] Meanwhile, the rotating shaft 53 drives the belt shaft 61 to rotate, the belt shaft 61 drives the belt shaft 63 to rotate through the belt 62, the belt shaft 63 drives the driving gear 65 to rotate, the driving gear 65 drives the driven gear 66 to rotate reversely, the driving gear 65 and the driven gear 66 rotate in the gear pump box 64, the volume increases when the gear teeth disengage, a local vacuum is formed, the suction pipe 67 generates suction, the through pipe 69 generates suction through the suction of the suction pipe 67, the suction pipe 61 and the suction pipe 62 generate suction inside through the suction of the through pipe 69, the suction pipe 61 and the suction pipe 62 absorb the resin mucilage filtered inside the receiving disc 44, and the resin mucilage is transmitted to the suction pipe 67 through the suction generated by the rotation of the driving gear 65 and the driven gear 66 in the gear pump box 64, and is discharged, at this time, the operator only needs to prepare a suitable container at the suction pipe 67 to collect, and the collection is completed. Since the resin mucilage has high viscosity and poor flowability, the flowability of the resin mucilage is improved by adding suction, the filtering rate and the discharging rate of the resin mucilage are improved, and the working efficiency of the whole equipment is improved.

[0034] Please refer to Figures 1-8 On the basis of the above embodiment, in another embodiment of the present application, the impurity removal device 7 comprises a group of impurity guide pipes 71, one end of the group of impurity guide pipes 71 penetrates through the impurity guide ring box 72, the other end of the group of impurity guide pipes 71 penetrates the inner side of the filter body 2, the bottom of the impurity guide ring box 72 is fixedly connected with the suction pipe 73, one end of the suction pipe 73 is fixedly connected with the side of the suction pipe 67, the top of the impurity guide ring box 72 is inserted with the sleeve cover 74. The impurity removal device 7 uses the suction force from the suction and pressure suction device 6 to uniformly absorb and process the resin impurities which are difficult to process after filtration without changing the working state of the suction and pressure suction device 6, and the suction force size is not changed, which is convenient for the staff to process. The inner wall of the suction pipe 73 is fixedly connected with the electric telescopic rod 75, a plurality of electric telescopic rods 75 are fixedly connected with the opening and closing ring 76 at the telescopic end, and the opening and closing ring 76 is in contact with one end of the suction pipe 73 close to the impurity guide ring box 72 in the initial state. The opening and closing ring 76 is designed to control the opening and closing of the suction force of the group of impurity guide pipes 71. One end of the suction pipe 73 penetrating through the filter body 2 is close to the second group of filter holes 43. Such design enhances the effect of the suction pipe 73 absorbing impurities.

[0035] In use, when the resin mucilage filtering and impurity removing is completed, at this time, the staff can start the electric telescopic rod 75 to drive its telescopic end to shrink, the electric telescopic rod 75 drives the opening and closing ring 76 to displace vertically downward, opens one end of the impurity guide pipe group 71, at this time, part of the suction force generated by the suction pipe 67 enters the inside of the impurity guide ring box 72 through the suction and pressure pipe 73 connected thereto, and through the impurity guide pipe group 71, the impurities contained in the resin mucilage gathered to the gap between the filter arc plate 41 and the filter body 2 are absorbed into the inside of the impurity guide ring box 72, finally, the plug cover 74 is opened to collect the impurities in the impurity guide ring box 72. Before the next resin mucilage filtering and impurity removing process starts, the plug cover 74 is inserted into the inside of the impurity guide ring box 72, then the electric telescopic rod 75 is started to drive its telescopic end to extend, at this time, part of the suction force in the suction pipe 67 is conducted to the inside of the suction and pressure pipe 73, which is blocked by the opening and closing ring 76, the impurity guide pipe group 71 loses suction force, preventing the impurity guide pipe group 71 from generating suction force to absorb the unfiltered resin mucilage when the next resin mucilage filtering and impurity removing process starts. The impurity removing equipment 7 uses the suction force from the suction and pressure suction equipment 6 to uniformly absorb and process the resin impurities that are difficult to process after filtering without changing the working state of the suction and pressure suction equipment 6, and the size of the suction force, which is convenient for the staff to process.
