As shown in fig. 1 to 4, the filter press of the present embodiment includes a frame 1, an oil cylinder 2 is disposed at one end of the frame 1, a hollow fixed filter plate 3 is fixedly disposed at the other end of the frame 1, at least two hollow movable filter plates 4 are disposed between the oil cylinder 2 and the fixed filter plate 3, the movable filter plate 4 nearest to the oil cylinder 2 is fixedly connected to an expansion link of the oil cylinder 2, and filter pressing grooves 5 are disposed on opposite surfaces of adjacent movable filter plates 4 or fixed filter plates 3. As can be seen from fig. 1, the side of the fixed filter plate 3 close to the adjacent movable filter plate 4 is provided with a filter pressing groove, the side of the movable filter plate 4 farthest from the fixed filter plate 3 close to the fixed filter plate 3 is provided with a filter pressing groove 5, and the side of the two sides of the middle movable filter plate 4 is respectively provided with a filter pressing groove 5.

The lower parts of two ends of the frame 1 are respectively provided with a roller 7, the lower ends of the movable filter plate 4 and the fixed filter plate 3 are respectively provided with a tensioning device 8, the lower ends of the fixed filter plate 3 and the movable filter plate 4 farthest from the fixed filter plate 3 are respectively provided with a tensioning device 8, and the tensioning devices 8 are all inclined towards the respective filter tanks 5. Two tensioning devices 8 are arranged at the lower end of each movable filter plate 4 in the middle, and the two tensioning devices incline towards the filter pressing grooves 5 on the surfaces of the two sides of the corresponding movable filter plate 4 respectively. Guide rollers 9 are arranged above the movable filter plates 4 and the fixed filter plates 3 which are adjacent to each other, and the guide rollers 9 are hinged with the movable filter plates 4 or the fixed filter plates 3 on two sides through connecting rods 20.

As can be seen from fig. 1, the roller 7 at the left end is wound with a filter cloth 10, the free end of the filter cloth 10 on the roller 7 passes through the filter pressing grooves 5 of the fixed filter plates 3 and the movable filter plates 4 in sequence through the tensioning device 8 and the guide roller 9 and is connected with the roller 7 at the right end, the roller 7 at the right end is in transmission connection with the driving device through the electric clutch 11, and the driving device can adopt a servo motor 12. Of course, the filter cloth can be wound on the right end roller 7, and the left end roller is in transmission connection with the driving device through the electric clutch.

Specifically, the fixed filter plate 3 is disposed on the rightmost side. For the space between two adjacent movable filter plates 4 on the leftmost side, the free end of the filter cloth on the roller 7 at the left end bypasses the lower side of the tension device 8 at the lower side of the movable filter plate 4 at the leftmost end, passes through the filter pressing groove 5 on the inner side surface of the movable filter plate 4 at the leftmost end, reaches the upper side of the guide roller 9 above the guide roller, and enters the next group of adjacent movable filter plates 4 after being guided by the guide roller, passes through the tension device 8 at the lower end of the adjacent movable filter plate 4, and thus sequentially passes through the subsequent movable filter plates 4 and the fixed filter plates 3 until the roller 7 at the rightmost end is fixedly connected with the roller 7 at the rightmost end.

Liquid inlet pipes 13 are arranged between every two adjacent movable filter plates 4 and fixed filter plates 3, clamping grooves 14 for clamping the liquid inlet pipes 13 are formed in the movable filter plates 4 or the fixed filter plates 3 corresponding to the liquid inlet pipes 13, and liquid outlet holes 15 are formed in the bottom ends of the movable filter plates 4 and the fixed filter plates 3. The liquid outlet hole 15 is connected with a water outlet hose.

The lower end of the frame 1 is provided with a base plate 16, the middle part of the base plate 16 is provided with a guide groove 17, and the liquid inlet pipe 13 can slide through the guide groove 17. When the movable filter plate 4 and the fixed filter plate 3 are pressed two by two, the liquid inlet pipe 13 can move along the extension direction of the guide groove 17 to adapt to the corresponding pressing position.

The inlet pipe 13 is connected to an inlet manifold 19 via a hose 18.

The movable filter plate 4 and the fixed filter plate 3 are connected with each other in a telescopic way through a chain 21.

The tensioning device 8 can adopt the following structure:

The working process of the filter press of the invention is as follows:

the electric clutch 11 between the servo motor 12 and the roller 7 at the leftmost end is in a separation state, the oil cylinder 2 at the left end moves, the telescopic rod of the oil cylinder extends out to drive the movable filter plate 4 to move rightwards, so that the movable filter plate 4 and the fixed filter plate 3 are pressed tightly, the corresponding liquid inlet pipe 13 is clamped by the clamping grooves 14 at the lower ends of the movable filter plate 4 and the fixed filter plate 3 which are adjacent in pairs, and the filter cloth 10 can be freely stretched along with the movement of the movable filter plate 4 in the process and automatically adapts to the position corresponding to the movable filter plate 4. After the movable filter plate 4 and the fixed filter plate 3 are contacted and pressed, waste liquid to be treated enters the filter pressing cavity 5 between every two adjacent filter pressing cavities in the movable filter plate 4 and the fixed filter plate 3 from the liquid inlet pipe 13 under high pressure, and pure liquid penetrates through the filter cloth 10, enters the hollow inner cavity of the movable filter plate 4 and flows out from the liquid outlet hole 15. Then the telescopic rod of the oil cylinder 2 retracts to drive each movable filter plate 4 and each fixed filter plate 3 to be separated in pairs, and filter cakes between every two adjacent movable filter plates 4 and fixed filter plates 3 fall down.

In the filter press of the invention, the filter cloth 10 is not sleeved on the movable filter plate 4, but is separated from the movable filter plate 4, the filter cloth 10 is wound on the roller 7 at one side, after the filter cloth 10 is used for a period of time, the electric clutch 11 is in a power-on combined state, the servo motor 12 is controlled to operate to drive the roller at the corresponding side to rotate, under the transmission action of the filter cloth 10, the roller 7 at the other side rotates in a driven manner, the filter cloth section with poor permeability is rotated to the roller 7 at the other side, under the guiding cooperation of the guiding of the guide roller 9 and the rotation of the roller 7, the clean filter cloth section is conveyed to the position between every two adjacent filter plates in the movable filter plate 4 and the fixed filter plate 3, the filter cloth 10 can be replaced without halt, the automation of the filter cloth 10 is replaced, and the filter cloth 10 positioned outside the filter press can be cleaned simultaneously when the filter press operates, and the filter cloth 10 can be cleaned without the shutdown, the filter pressing efficiency is greatly improved.

In addition, according to the structure of the filter press, when the movable filter plates 4 and the fixed filter plates 3 are separated in pairs, the distance between the adjacent filter cloth 10 in the movable filter plates 4 and the fixed filter plates 3 is narrow, and the dropping of mud blocks is facilitated.
