[0015] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0016] An automatic unloading filter press, such as Figure 1 As shown, the system includes a frame 1, a filtering mechanism 2, an extrusion plate 3, a positioning plate 4, a hydraulic press 5, and a PLC controller. The frame 1 has a fixed positioning plate 4 at one end and an extrusion plate 3 at the other end, with the extrusion plate 3 slidably connected to the frame 1. The hydraulic press 5 is fixedly connected to the extrusion plate 3. Several slidably connected filtering mechanisms 2 are mounted on the frame 1, positioned between the extrusion plate 3 and the positioning plate 4. The PLC controller controls the hydraulic press 5, which pushes the extrusion plate 3 to move on the frame 1, controlling the distance between the extrusion plate 3 and the positioning plate 4. This ultimately presses or releases the filtering mechanisms 2 positioned between the extrusion plate 3 and the positioning plate 4, completing the filtration process. Each filtering mechanism 2 has an inlet pipe 21, through which the slurry enters the filtering mechanism 2. The PLC controller is connected to both the hydraulic press 5 and the filtering mechanisms 2, controlling their operation.

[0017] The filtering mechanism 2 comprises a left filter plate assembly 22, a right filter plate assembly 23, a discharging assembly 24, and filter cloth. The right side of the left filter plate assembly 22 is provided with a concave filter chamber A 25. The filter cloth is arranged outside the concave filter chamber A 25, that is, the filter cloth is laid on the concave filter chamber A 25. Then, a clamping column is arranged outside the concave filter chamber A 25. The filter cloth is connected with the concave filter chamber A 25 through the clamping column. The filter cloth is laid relatively loosely. The filter cloth is fixed on the concave filter chamber A 25 through positioning buckles on the periphery of the concave filter chamber A 25. The left side of the right filter plate assembly 23 is provided with a concave filter chamber B 26. The filter cloth is arranged outside the concave filter chamber B 26. The laying method and principle are the same as those of the concave filter chamber A 25. A plurality of mounting holes are arranged in the concave filter chamber A 25 and the concave filter chamber B 26. Preferably, the mounting holes are uniformly arranged at the bottom of the concave filter chamber A 25 and the concave filter chamber B 26. The discharging assembly 24 is arranged in the mounting hole. The discharging assembly 24 is connected with the PLC controller. The discharging assembly 24 can push out the material residue in the left filter plate assembly 22 or the right filter plate assembly 23 during work, so that the material residue is naturally dropped. Manual operation is avoided. The concave filter chamber A 25 and the concave filter chamber B 26 are butted, that is, the concave filter chamber A 25 and the concave filter chamber B 26 form a complete filtering chamber after being butted. The pulp inlet pipe 21 is arranged above the left filter plate assembly 22 and the right filter plate assembly 23. The water drainage channel 27 is arranged below the left filter plate assembly 22 and the right filter plate assembly 23. The pulp inlet pipe 21 is arranged above in order to utilize gravity to facilitate feeding. At this time, the filtered water after feeding on the upper side is discharged through the water drainage channel 27 on the lower side. The whole filtering process is more reasonable. In order to facilitate the collection of the pulp, the filter press further comprises a material receiving groove 6.

[0018] The discharging assembly 24 comprises a telescopic rod 241 and a driving motor 242. The driving motor 242 is arranged at the bottom of the mounting hole and is connected with the PLC controller. The telescopic rod 241 is arranged outside the driving motor 242. At this time, the driving motor 242 is controlled by the PLC controller when work is needed, so that the telescopic rod 241 is extended or retracted. When the telescopic rod 241 is extended, the material residue on the concave filter chamber A 25 and the concave filter chamber B 26 can be pushed outwards, so that the material residue is naturally dropped, thereby reducing manual intervention and improving efficiency. The top of the telescopic rod 241 and the bottom of the mounting hole are sealingly connected through a waterproof film. The purpose of this setting is that if a large amount of pulp enters this space, the driving motor 242 will be affected. The waterproof film protects the driving motor 242 and forms a sealed space. The waterproof film does not affect the extension and retraction of the telescopic rod 241.

[0019] The chamfer is arranged on the bottom of the concave filter chamber A25 and the concave filter chamber B26 in a circumferential direction, so that the concave filter chamber A25 and the concave filter chamber B26 form a groove without obvious dead angle. The structure can avoid forming slag dead angle, so that the slag is more easily dropped out. If the bottom is a right angle, the material is easy to be stuck.

[0020] The warp density of the filter cloth is 519 per 10 cm, and the weft density of the filter cloth is 220 per 10 cm.

[0021] The left filter plate assembly 22 is provided with a groove 221 in a circumferential direction, and the right filter plate assembly 23 is provided with a protrusion 231 which is in butt joint with the groove 221. The structure can make the left filter plate assembly 22 and the right filter plate assembly 23 fully adhere to each other, so as to avoid that the slurry entering from the upper feeding pipe directly flows out.

[0022] The working mode and principle are as follows: the PLC controller moves the extrusion plate 3, and then extrudes a plurality of filter mechanisms 2 together. At this time, the slurry enters the inside of the filter mechanism 2 through the feeding pipe. After the slurry enters from the top, the filter cloth is filtered, the filter residue is blocked by the filter cloth and stays in the filter mechanism 2, and the filtered water is discharged through the lower drainage channel 27. When the filter residue in the filter mechanism 2 reaches a specified height, the feeding pipe stops feeding. At this time, the PLC control mechanism controls the extrusion plate 3 to move outward to leave enough space. Each filter mechanism 2 is separated by manual intervention. Then, the left filter plate assembly 22 and the right filter plate assembly 23 are separated. At this time, the PLC controller starts to control the driving motor 242 in the mounting hole to drive the telescopic rod 241 to stretch out, that is, the filter residue adhered to the left filter assembly or the right filter assembly is pushed out and falls into the lower receiving groove 6. At this time, the whole working process is completed.
