Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] See Figures 1 to 4 This embodiment discloses a filter press device, including two support plates 100, with two side plates 110 connected between them. A guide rail 130 is connected above the two support plates 100 via a connecting plate 120. Multiple filter plates 200 are disposed below the guide rail 130, and each filter plate 200 has a filter groove 201. The filter plates 200 are connected to the guide rail 130 via a pulley structure that cooperates with the guide rail 130, thereby allowing the filter plates 200 to move along the guide rail 130. The filter plate 200 is placed between two side plates 110. The right support plate 100 of the two support plates 100 is equipped with a push rod 310 extending between the two side plates 110. The push rod 310 is connected to a hydraulic cylinder, which can push the push rod 310 to move. A pressure plate 300 is provided at the end of the push rod 310 facing the filter plate 200. The push rod 310 moves and pushes the pressure plate 300 to squeeze the filter plate 200, so that the filter plates 200 squeeze each other, thereby squeezing and filtering the filter cake.

[0020] The upper and lower ends of the filter plate 200 are provided with inclined fixed channels 210. The upper and lower ends of the filter plate 200 are connected to the filter tank 201 through the fixed channels 210. The filter cloth 400 enters the fixed channel 210 from the upper and lower ends of the filter plate 200 and then passes through the fixed channel 210 into the filter tank 201.

[0021] The filter plate 200 is provided with a rotating groove 220 and a first telescopic groove 230 communicating with the rotating groove 220. The first telescopic groove 230 is connected to the fixed channel 210. A first telescopic member 250 is provided in the first telescopic groove 230. A first guide groove 231 is provided on the side wall of the first telescopic groove 230. A first baffle 251 extending into the first guide groove 231 is provided on the first telescopic member 250. A first spring 232 is provided in the first guide groove 231. The first spring 232 pushes the first telescopic member 250 to move toward the end where the rotating body 240 is located. The surface of the rotating body 240 is provided with a first locking groove 241 recessed towards the center. The end of the first telescopic member 250 facing the rotating body 240 is provided with a first inclined surface 253. The end of the first telescopic member 250 facing the rotating body 240 is embedded in the first locking groove 241. The rotating body 240 causes the first inclined surface 253 to move along the side wall of the first locking groove 241, thereby moving the end of the first telescopic member 250 facing the rotating body 240 to the surface of the rotating body 240, thereby pushing the movement of the first telescopic member 250.

[0022] The first telescopic member 250 is provided with a pressure block 252 at one end facing the fixed channel 210. The fixed channel 210 is provided with a protrusion 211 on the side opposite to the pressure block 252. The rotating body 240 drives the first telescopic member 250 to move and also drives the pressure block 252 to move, clamping the filter cloth 400 between the protrusion 211 and the pressure block 252, thereby fixing the filter cloth 400.

[0023] The filter plate 200 is provided with a second telescopic groove 260 communicating with the rotating groove 220. A second telescopic rod 270 abutting against the rotating body 240 is provided in the second telescopic groove 260. A second guide groove 261 is provided on the side wall of the second telescopic groove 260. A second baffle 271 extending into the second guide groove 261 is provided in the second guide groove 261, a second spring 262 abutting against the second baffle 271. The rotating body 240 is provided with a second locking groove 242. A second inclined surface 272 is provided at the first end of the second telescopic rod 270 that is embedded in the second locking groove 242. The second telescopic rod 270 is embedded in the second locking groove 242 to restrict the rotation of the rotating body 240 and prevent the rotating body 240 from slipping. After the rotating body 240 is rotated by external force, the second inclined surface 272 moves along the side wall of the second locking groove 242 to the surface of the rotating body 240, so that the second telescopic rod 270 abuts against the surface of the rotating body 240.
