At the same time, the solid-liquid mixture that falls onto the main net will roll with the main net, wherein the liquid will be separated from the solid through the mesh holes on the surface of the main net to achieve a filtering effect. At the same time, when the drum rotates, it will drive the push rod to squeeze the baffle plate, so that the fixed plate drives the surface ejector pin to reciprocate and shuttle back and forth through the mesh holes on the surface of the main net, thereby increasing the fluidity of the viscous liquid in the mesh holes, preventing the viscous liquid from clogging the mesh holes, avoiding affecting the normal use of the device, and improving work efficiency.

[0015] (2) In the filtering device with an anti-clogging structure, the fixed plate drives the arc plate to move when it moves back and forth, so that the secondary net continues to shake, and the mixture that has completed the initial filtration is subjected to secondary filtration, so that the liquid and solid in the mixture fall into the liquid collecting tank a, the liquid collecting tank b, and the impurity tank respectively. The secondary filtration of the mixture improves the accuracy of the required production raw materials, and at the same time facilitates the management of the staff and improves the production efficiency.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-7The utility model provides a technical solution: an anti-clogging filtering device, including a base 1 and a storage box 2, the storage box 2 is fixedly installed on the top of the base 1, a feed port is opened on the top of the storage box 2, and a discharge port 9 is opened at the bottom of the storage box 2. A motor 3 is fixedly installed on the surface of the base 1, a rotating drum 4 is fixedly installed on the free end of the motor 3, a main net 7 is sleeved on the surface of the rotating drum 4, and mesh holes are opened on the surface of the main net 7. A bracket 6 is fixedly installed on the surface of the base 1, a fixed plate 42 is slidably installed on the surface of the bracket 6, a thimble 43 is fixedly installed on the surface of the fixed plate 42, a baffle 44 is fixedly installed on the surface of the fixed plate 42, and a push rod 41 is fixedly installed on the outer wall of the rotating drum 4, which continuously shuttles through the mesh holes on the surface of the main net 7 through the thimble 43 to increase the fluidity of the liquid in the mesh holes and prevent the mesh holes from being blocked.

[0026] There are two groups of rotating drums 4, one of which is fixedly installed at the right end of the top of the base 1, and the other is rotatably installed at a position near the left end of the top of the base 1, and the horizontal height of the rotating drum 4 at the right end is twice the horizontal height of the rotating drum 4 at the left end. The outer wall of the rotating drum 4 is in contact with the inner wall of the main net 7. The height difference between the two groups of rotating drums 4 makes the main net 7 inclined, so that the solid-liquid mixture rolls on the surface of the main net 7.

[0027] A liquid collecting tank a5 is slidably installed inside the base 1, a liquid collecting tank b8 is slidably installed inside the base 1, and a collecting tank 10 is slidably installed inside the base 1. The liquid collecting tank a5, the liquid collecting tank b8 and the collecting tank 10 can classify and centrally store the filtered solids and liquids for easy management.

[0028] The collecting tank 10 is between the collecting tank a5 and the collecting tank b8.

[0029] An elastic member is provided between the bracket 6 and the fixing plate 42 , and the elastic force of the elastic member facilitates the fixing plate 42 to be reset after being moved.

[0030] A secondary net 73 is slidably mounted on the surface of the base 1, an arc plate 72 is fixedly mounted on the surface of the secondary net 73, a pressure rod 71 is fixedly mounted on the surface of the fixed plate 42, the pressure rod 71 squeezes the arc plate 72 so that the arc plate 72 drives the secondary net 73 to move, and when the push rod 41 is no longer in contact with the baffle 44, the fixed plate 42 is reset through the elastic member.

[0031] The auxiliary net 73 is set at an angle, and a spring is arranged between the auxiliary net 73 and the base 1. The side of the arc plate 72 close to the pressure rod 71 is set in an arc shape, so that when the pressure rod 71 contacts the surface of the arc plate 72, it can push the arc plate 72 to move, thereby driving the auxiliary net 73 to move.

[0032] During operation, when it is necessary to filter the solid-liquid mixture, the discharge port 9 at the bottom of the storage box 2 is opened, and the solid-liquid mixture in the storage box 2 falls from the discharge port 9. At the same time, the motor 3 is turned on to make the free end of the motor 3 start to rotate, and the rotating free end of the motor 3 drives the right rotating drum 4 to rotate. The rotating right rotating drum 4 uses the friction between it and the main net 7 to push the main net 7 to roll. The surface of the rolling main net 7 will contact the solid-liquid mixture falling from the discharge port 9. After contacting the surface of the main net 7, the liquid in the solid-liquid mixture will continue to fall through the mesh holes on the surface of the main net 7 until it falls into the liquid collecting tank b8 for centralized storage. At the same time, the solid matter that has not passed through the mesh holes on the surface of the main net 7 continues to roll with the main net 7 until it reaches the top of the secondary net 73.

[0033] At the same time, when the drum 4 rotates, it drives the push rod 41 on the surface of the drum 4 to rotate. When the rotating push rod 41 rotates to a position close to the baffle 44, it squeezes the baffle 44 to make the baffle 44 move toward the base 1. The moving baffle 44 drives the fixed plate 42 to move toward the base 1, and the moving fixed plate 42 drives the surface ejector 43 to move. When the push rod 41 continues to rotate until it is away from the baffle 44, the push rod 41 releases the limit on the baffle 44, and the released baffle 44 is reset under the elastic force of the elastic member provided between the bracket 6 and the baffle 44. The reset baffle 44 drives the fixed plate 42 to reset, so that the fixed plate 42 drives the ejector 43 to reset, so as to achieve the effect of making the ejector 43 reciprocate up and down. At the same time, the ejector 43 that continues to reciprocate shuttles back and forth through the mesh holes on the surface of the main net 7 to prevent the mesh holes on the surface of the main net 7 from being blocked by the viscous liquid.

[0034] At the same time, the moving fixed plate 42 drives the pressure rod 71 to move in the direction of the curved plate 72. Since the side of the curved plate 72 close to the pressure rod 71 is an inclined surface, when the moving pressure rod 71 contacts the surface of the curved plate 72, it will push the curved plate 72 to move in the direction close to the base 1. The moving curved plate 72 drives the auxiliary net 73 to move. When the fixed plate 42 is reset and lifted up, it drives the pressure rod 71 to lift up and release the limit on the curved plate 72. At the same time, the auxiliary net 73 is reset under the elastic force of the spring set between the base 1 and the auxiliary net 73. Therefore, when the fixed plate 42 continues to reciprocate, it continuously drives the pressure rod 71 to squeeze the arc plate 72 and then lift it up, so that the arc plate 72 continuously drives the auxiliary net 73 to slide and reset, and performs secondary filtration on the objects that are about to fall onto the surface of the auxiliary net 73. The remaining liquid after the initial filtration of the main net 7 will pass through the mesh holes on the surface of the auxiliary net 73 and fall into the liquid collecting tank a5. At the same time, the solids that do not pass through the mesh holes will roll to the collecting tank 10 for centralized storage, thereby improving the classification accuracy of solids and liquids through secondary filtration.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
