[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 、 Figure 3The utility model provides an embodiment of a plate pulling trolley for a filter press, comprising a guide rail 1, which is used to support the movement of the walking plate 3. The outer periphery of the guide rail 1 is slidably connected to the walking plate 3. The walking plate 3 serves as the main structure of the plate pulling trolley and drives the mounting plate 7 to move. A mounting plate 7 is provided on the top side of the walking plate 3. The mounting plate 7 is used to install and fix other structures. A limit hook 4 and a draw hook 6 are respectively installed on the top of the mounting plate 7. The limit hook 4 can limit the movement of the walking plate 3, and the draw hook 6 can pull the filter plate inside the filter press to move with the walking plate 3. A hammer assembly 5 is provided inside the mounting plate 7, and the hammer assembly 5 is used to hammer the filter plate; the hammer assembly 5 includes a mounting rod 505, which is installed inside the mounting plate 7. The mounting rod 505 rotates inside the mounting plate 7 to drive the hammer block 501 to rotate. The hammer block 501 is installed on the top of the mounting rod 505. The hammer block 501 can be rotated to hammer the filter plate. A support shaft 503 is installed inside the mounting plate 7. The support shaft 503 rotates inside the mounting plate 7 to support the eccentric wheel 504 to rotate. The eccentric wheel 504 is fixedly connected to the outer periphery of the support shaft 503. The outer periphery of the eccentric wheel 504 abuts against one side of the mounting rod 505. The rotation of the eccentric wheel 504 can push the mounting rod 505 to rotate. The outer periphery of the support shaft 503 is fixedly connected to the gear 507. A plurality of evenly distributed teeth 502 are installed on the top side of the guide rail 1. The gear 507 is meshed with the teeth 502, and the gear 507 can move with the mounting plate 7. The engagement of the gear 507 with the teeth 502 enables the gear 507 to drive the support shaft 503 to rotate during the rotation process. A tension spring 506 is installed on one side of the mounting rod 505. The left end of the tension spring 506 is installed inside the mounting plate 7. The contraction of the tension spring 506 can pull the mounting rod 505 to rotate.

[0035] Reference Figure 1 、 Figure 4 and Figure 5, a connecting assembly 2 is provided inside the walking plate 3, and the connecting assembly 2 is used to connect the walking plate 3 and the mounting plate 7 to each other. The connecting assembly 2 includes two connecting plates 201, and the connecting plate 201 is installed on the bottom side of the mounting plate 7. The connecting plate 201 is inserted into the walking plate 3 to connect the walking plate 3 and the mounting plate 7 to each other. The walking plate 3 is slidably connected with a moving shaft 203. The movement of the moving shaft 203 can drive the rotating rod 202 to rotate. The outer periphery of the moving shaft 203 is connected to two rotating rods 202. The rotating rod 202 can drive the connecting shaft 205 to move during its rotation. One end of the rotating rod 202 is rotatably connected to the connecting shaft 205. The connecting plate 201 is opened inside. A groove is provided, and one end of the connecting shaft 205 is slidably connected to the inside of the groove. After one end of the connecting shaft 205 is inserted into the groove, the connecting plate 201 can be fixed to the inside of the walking plate 3. A push plate 204 is installed on the outer periphery of the connecting shaft 205. Two limit grooves 10 are opened inside the walking plate 3. The push plate 204 is slidably connected to the inside of the limit groove 10. The push plate 204 slides inside the limit groove 10 to limit the movement of the connecting shaft 205. A spring 206 is provided on the outer periphery of the connecting shaft 205. One end of the spring 206 abuts against one side of the push plate 204. The other end of the spring 206 is installed inside the walking plate 3. The spring 206 can push the connecting shaft 205 to move through the push plate 204.

[0036] Reference Figure 1 、 Figure 2 The limit hook 4 and the pull hook 6 are both installed with a fixed shaft 8 at the bottom. The two fixed shafts 8 are respectively fixed on the top and inside of the mounting plate 7 to install the torsion spring 9 and support the rotation of the limit hook 4 and the pull hook 6. The outer periphery of the fixed shaft 8 is provided with a torsion spring 9. One end of the two torsion springs 9 is respectively installed at the bottom of the limit hook 4 and the pull hook 6, and the other end of the two torsion springs 9 is installed at the top of the mounting plate 7. The torsion spring 9 can push the limit hook 4 and the pull hook 6 to rotate so that the limit hook 4 and the pull hook 6 are reset.

[0037] Working Principle: During operation, the traveling plate 3 of the plate pulling trolley moves along the guide rail 1, driving the plate pulling trolley toward the filter plate. During the movement of the plate pulling trolley, the filter plate pushes the hook 6 to rotate. When the filter plate contacts the limit hook 4, the plate pulling trolley stops moving, so that the filter plate is on the side facing the limit hook 4 and the hook 6. Then the plate pulling trolley starts to move back. During the backward movement of the plate pulling trolley, the hook 6 can drive the filter plate to move simultaneously with the plate pulling trolley, thus completing the plate pulling operation. During the movement of the plate pulling trolley, the gear 507 and the teeth 502 engage with each other, so that the gear 507 drives the eccentric wheel 504 to rotate through the support shaft 503. During the rotation of the eccentric wheel 504, the mounting rod 505 is rotated. The rotation of the mounting rod 505 drives the hammer block 501 to repeatedly strike the filter plate, thereby causing the filter cake on the filter plate surface to fall off.

[0038] When the plate pulling trolley needs to be repaired, the movable shaft 203 can be pressed to move toward the inside of the walking plate 3. During the movement of the movable shaft 203, the two rotating rods 202 can be driven to rotate. During the rotation of the rotating rods 202, the connecting shaft 205 can be driven to move so that one end of the connecting shaft 205 can be pulled out from the inside of the connecting plate 201. After that, the mounting plate 7 and the walking plate 3 can be separated from each other to facilitate the maintenance of the plate pulling trolley.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
