[0031] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides an automatic material shaking and slag unloading device in a filter press unloading system, comprising a frame 1, two parallel connecting beams 2 are fixedly connected on both sides of the frame 1, a clamping plate 3 is fixedly connected to the surface of one side of the frame 1 extending to between the two connecting beams 2, a plurality of filter plates 4 are placed on the surface of the connecting beam 2 on the side away from the clamping plate 3, filter plate sliders 41 are fixedly connected to the bottom ends of the two side surfaces of the filter plates 4, a thrust plate 5 is fixedly connected to the surface of one end of the connecting beam 2 away from the filter plate 4, slide rails 6 are fixedly connected to the sides of the two connecting beams 2, a plate pulling trolley 7 is sleeved on the slide rails 6, the two plate pulling trolleys 7 are fixedly connected to the surfaces on the side away from the connecting beam 2 with a telescopic structure, and the tops of the two telescopic structures are fixedly connected to a limited baffle structure.

[0032] The limit baffle structure includes a limit rod 9 fixed to one end of the telescopic structure, and a limit baffle groove 92 is provided on the surface of one side of the limit rod 9 close to the filter plate 4; when it is necessary to unload the mud cake on the filter plate 4, the filter plate 4 is pulled to the limited position of the connecting beam 2 by the plate pulling trolley 7, and the telescopic structure is controlled to rise and fall by the controller, thereby controlling the limit baffle structure to descend and be sleeved on the upper end of the filter plate 4, and then the plate pulling trolley 7 moves back and forth to drive the filter plate 4 to reciprocate, so that the filter plate 4 and the plate pulling trolley 7 collide with each other, and under the horizontal force of the collision, the mud cake on the filter plate 4 When the filter plate 4 falls, and the filter plate 4 collides with the plate pulling trolley 7, the limit baffle structure will limit the top of the filter plate 4, and at the same time, the top of the filter plate 4 will also collide with the two sides of the limit baffle groove 92 inside the limit baffle structure. During the collision, due to the interaction force between the limit baffle groove 92 and the top of the filter plate 4, the bottom of the filter plate 4 will move in the opposite direction, and the filter plate 4 will generate an angle with the limit baffle groove 92. The bottom of the filter plate 4 correspondingly generates a force in the direction of the angle, thereby limiting the filter plate 4 while assisting in increasing the unloading effect of the mud cake on the filter plate 4.

[0033] like Figure 3 As shown, the upper surface of the pulling plate trolley 7 is fixedly connected with a top claw 71 at one end close to the pressing plate 3, and the other end is fixedly connected with a pushing plate claw 72. The outer walls of the bottom ends of the top claw 71 and the pushing plate claw 72 are wrapped and fixed with rubber sleeves 73. The top claw 71 and the pushing plate claw 72 are used to pull the filter plate 4 to move. The rubber sleeve 73 can effectively buffer the top claw 71 and the pushing plate claw 72 when the filter plate 4 collides with each other, protect the top claw 71 and the pushing plate claw 72 from damage and increase the service life of the top claw 71 and the pushing plate claw 72. At the same time, the rubber sleeve 73 is directly sleeved on the top claw 71 and the pushing plate claw 72, which can be easily replaced when the rubber sleeve 73 is damaged. The top spacing between the top claw 71 and the pushing plate claw 72 is 1.5 times the width of the filter plate 4.

[0034] like Figure 4 and Figure 5As shown, the telescopic structure includes a telescopic frame 8 fixed to the outer wall of the two plate pulling trolleys 7, and telescopic screws 81 are fixedly connected to the two ends of the telescopic frame 8. A telescopic motor 82 is fixedly connected to the surface of one end of the telescopic frame 8 close to the plate pulling trolley 7. The output end of the telescopic motor 82 passes through the surface wall of the telescopic frame 8 and is fixedly connected to the telescopic screw 81. A screw nut 83 is sleeved on the outer wall of the telescopic screw 81, and the limit baffle structure is fixedly connected to the telescopic screw 81 through the screw nut 83; the telescopic screw 81 is driven to rotate by the forward and reverse rotation of the telescopic motor 82, so that the screw nut 83 can reciprocate on the telescopic screw 81, thereby driving the limit rod 9 on the limit baffle structure to reciprocate. When the plate pulling trolley 7 reaches the specified position, the limit rod 9 is driven to descend by controlling the movement of the screw nut 83, thereby assisting in limiting. When the unloading work is completed, the limit rod 9 is driven to rise, so that the limit baffle structure will not affect the work of the plate pulling trolley 7.

[0035] like Figure 5 As shown, one side surface of the limit retaining groove 92 is fixedly connected with the air pipe 91, and the inner surface wall of the limit retaining groove 92 close to the air pipe 91 is fixedly connected with the nozzle 911, and the nozzle 911 penetrates the surface wall of the limit rod 9 and is connected with the air pipe 91; the inner surface wall of the limit retaining groove 92 is fixedly connected with the protective sheet 93 on both sides, and the width of the limit retaining groove 92 is twice the thickness of the filter plate 4; the edge position of the nozzle 911 is in the same vertical plane with the top surface of the push plate claw 72, and a plurality of nozzles 911 are provided, and the plurality of nozzles 911 are respectively sandwiched at 75° with the installation plane of the limit rod 9. Angle installation, when the pulling plate trolley 7 reaches the specified position, the limit rod 9 drops down. Since the edge position of the jet head 911 is in the same vertical plane with the top surface of the push plate claw 72, when the limit rod 9 drops to the upper end of the filter plate 4, the filter plate 4 is just stuck in the limit stop groove 92 and contacts with the jet head 911. While impacting and unloading, the air pipe 91 is externally connected to the blower, and the side of the filter plate 4 with the mud cake is blown through the jet head 911 to assist in unloading. At the same time, the protective sheet 93 is a silicone gasket to prevent the limit rod 9 from being damaged when the filter plate 4 collides with the limit stop groove 92.

[0036] The technical solution provided by the utility model provides a limit baffle structure. The limit baffle groove on the limit baffle structure will limit the top of the filter plate. At the same time, the top of the filter plate will collide with the two sides of the limit baffle groove. During the collision, due to the interaction force between the limit baffle groove and the top of the filter plate, the bottom of the filter plate will move in the opposite direction. The filter plate will generate an angle with the limit baffle groove, and the bottom of the filter plate will generate a force in the direction of the angle. The limit baffle structure not only limits the filter plate for protection, but also helps to increase the unloading effect of the mud cake on the filter plate.

[0037] By setting the rubber sleeve, the rubber sleeve can effectively cushion the top claw and the push plate claw when they collide with the filter plate, protect the top claw and the push plate claw from damage and increase the service life of the top claw and the push plate claw. At the same time, the rubber sleeve is directly mounted on the top claw and the push plate claw, which can be easily replaced when the rubber sleeve is damaged.

[0038] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
