[0002] A chamber filter press uses a plurality of filter plates to form a filter chamber. Then, a suspension and washing water are introduced inside the filter chamber, and the filtrate is discharged to achieve the function of separating solids and liquids. During the filtration process, a water retaining device is required to prevent the filtrate from splashing out from the inside of the filter chamber.

[0003] A water retaining device for a chamber filter press with the publication number CN214551434U has a frame as the main body. Cross beams are arranged on both sides of the frame. Filter plates are evenly arranged between the cross beams. Water retaining devices are arranged on both sides of the cross beams. A collecting device is arranged at the bottom side of the water retaining device. During use, when squeezing the filter plates, the two side water retaining plates can be pushed to be distributed on both sides of the filter plates, so as to block the water columns squeezed out from both sides of the filter plates, thereby preventing the filtrate from splashing out and causing waste of resources.

[0004] The above-mentioned water retaining device for a chamber filter press still has problems. It uses a plurality of water retaining plates, which are large in volume and cannot be disassembled. After the filtration process is completed, it is not convenient to clean and maintain the filter plates, resulting in the processing efficiency of the chamber filter press. Therefore, a water retaining device for a chamber filter press is proposed. Summary of the Utility Model

The utility model proposes a water retaining device for a chamber filter press.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A water retaining device for a chamber filter press according to the utility model includes a frame; a water retaining mechanism is arranged on the top side of the frame, a positioning mechanism is arranged on both sides of the frame, a filtering mechanism is arranged inside the frame, and a fixed disk is fixed at one end of the top side of the frame.

One end of the water retaining cloth is fixed on the side surface of the moving frame. The roller is rotatably connected with the fixed disk. Through the structure of the roller and the water retaining cloth, while realizing the water retaining function, its occupied volume is smaller, and the water retaining cloth can be automatically wound up, making the equipment more flexible and convenient to use.

[0008] Preferably, the positioning mechanism includes a moving frame. Fixed plates are fixed at the bottom ends of both sides of the moving frame. A plug rod is slidably inserted through the side surface of the fixed plate. A limiting cap is fixed at one end of the plug rod. A spring is fixedly connected between the limiting cap and the fixed plate, and the spring is sleeved on the plug rod. Positioning holes are uniformly formed at the top ends of both sides of the frame. One end of the plug rod is inserted and installed in the inner side of the positioning hole. Support plates are fixed at both ends of the top side of the frame.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Through the structural design of a water retaining device for a chamber filter press, by setting a water retaining mechanism, during the use of the filter press, the moving frame is pulled, so that it slides in the inner side of the limiting groove under the cooperation of the limiting block, thereby pulling out the water retaining cloth from the roller. At this time, the water retaining cloth covers both sides of the frame, which can prevent the filtrate from splashing out during the filtering process. After use, the moving frame can be reset. At this time, the torsion spring drives the turntable and the roller to reverse by its own elastic force, and winds up the water retaining cloth, solving the problem that the existing water retaining structure has a large volume and affects the subsequent cleaning and maintenance of the equipment.

[0012] 2. Through the structural design of a water retaining device for a chamber filter press, by setting a positioning mechanism, the limiting cap is pulled to pull out the plug rod from the inner side of the positioning hole, thereby releasing the fixation of the moving frame. After the moving frame is moved to the selected positioning hole position, the limiting cap is released. Under the action of the elastic force of the spring, the plug rod is pulled to be inserted into the inner side of the positioning hole again, preventing the water retaining cloth from loosening and retracting during use, thus facilitating the operation of the operator.

At the top end of the round rod 3, a turntable 4 is rotatably installed. At the bottom side of the turntable 4, a roller 5 is fixed. A water retaining cloth 7 is wound around the roller 5. A torsion spring 6 is fixedly connected between the turntable 4 and the fixed disk 2. At the top side of the frame 1, limiting grooves 8 are symmetrically formed. Inside the limiting grooves 8, a moving frame 10 is slidably installed through cooperation with limiting blocks 9. On both sides of the frame 1, water storage tanks 101 are fixed. One end of the water retaining cloth 7 is fixed to the side surface of the moving frame 10. The roller 5 is rotatably connected to the fixed disk 2. During operation, when encountering the problem that the existing water retaining structure is large in volume and affects the subsequent maintenance of the equipment, through the structure of the water retaining mechanism, during the use of the filter press, the moving frame 10 is pulled, so that it slides inside the limiting grooves 8 under the cooperation of the limiting blocks 9, thereby pulling out the water retaining cloth 7 from the roller 5. At this time, the water retaining cloth 7 drives the roller 5 and the turntable 4 to rotate, thus tightening the torsion spring 6. At the same time, the water retaining cloth 7 covers both sides of the frame 1, which can prevent the filtrate from splashing out during the filtration process. After use, the moving frame 10 can be reset. At this time, the torsion spring 6 drives the turntable 4 and the roller 5 to reverse by its own elastic force, winding up the water retaining cloth 7 to prevent it from affecting the subsequent cleaning and maintenance of the filter press.

[0023] Please refer to Figure 3 As shown in the figure, the positioning mechanism includes a moving frame 10. At the bottom ends of both sides of the moving frame 10, fixing plates 11 are fixed. A plug rod 12 is slidably inserted through the side surface of the fixing plate 11. At one end of the plug rod 12, a limiting cap 13 is fixed. A spring 14 is fixedly connected between the limiting cap 13 and the fixing plate 11, and the spring 14 is sleeved on the plug rod 12. At the top ends of both sides of the frame 1, positioning holes 15 are evenly formed. One end of the plug rod 12 is inserted inside the positioning holes 15. At both ends of the top side of the frame 1, support plates 18 are fixed. During operation, when encountering the problem that the water retaining structure is prone to loosen and retract, through the structure of the positioning mechanism, the limiting cap 13 is pulled to pull out the plug rod 12 from inside the positioning holes 15, thereby releasing the fixation of the moving frame 10. After the moving frame 10 is moved to the position of the selected positioning hole 15, the limiting cap 13 is released. Under the action of the elastic force of the spring 14, the plug rod 12 is pulled to be inserted back inside the positioning holes 15, preventing the water retaining cloth 7 from loosening and retracting during use, thus facilitating the operation of the operator.

[0024] Please refer to Figure 4As shown in the figure, the filtering mechanism includes a support plate 18, a hydraulic cylinder 19 is fixed inside the support plate 18, a hydraulic rod 20 is slidably installed inside the hydraulic cylinder 19, sliding grooves 16 are symmetrically arranged on the top side of the frame 1, filter plates 17 are evenly slidably installed inside the sliding grooves 16, one end of the hydraulic rod 20 is fixedly connected to the filter plate 17, and support legs 21 are fixed at the four corners of the bottom side of the frame 1; during operation, when there is a problem that the existing filter press has a complex structure and is not convenient to use, through the structure of the filtering mechanism, when carrying out filter pressing processing, the water blocking structure is set at the required position. At this time, the hydraulic cylinder 19 can be controlled to extend the hydraulic rod 20 inside it, so as to push the filter plate 17 to slide inside the sliding groove 16, so that the filter plates 17 are tightly connected in sequence, thereby carrying out filter pressing processing, and the filtrate flowing out from the inside of the frame 1 during the filter pressing process will be temporarily stored inside the water storage tank 101 to prevent waste of water resources.

[0025] Please refer to Figure 5 As shown in the figure, a drain hole 22 is opened at the bottom side of one end of the water storage tank 101, and the drain hole 22 communicates with the bottom end inside the water storage tank 101; during operation, when there is a problem that the filtrate inside the water storage tank 101 is not convenient to discharge, through the structure of the drain hole 22, the liquid inside the water storage tank 101 can be centrally discharged and collected from the drain hole 22, so that the equipment is more convenient to use.

[0026] Working principle: The chamber filter press uses multiple filter plates arranged to form a filter chamber. Then, a suspension and washing water are introduced inside the filter chamber, and the filtrate is discharged to achieve the function of separating solids and liquids. During the filtration process, a water blocking device is required to prevent the filtrate from splashing out from the inside of the filter chamber. The existing water blocking device uses multiple water baffle plates, which are large in volume and cannot be disassembled. After the filtration process is completed, it is inconvenient to clean and maintain the filter plates, resulting in a low processing efficiency of the chamber filter press. To solve this problem, by setting a water blocking mechanism and a positioning mechanism, the hydraulic cylinder 19 is controlled to extend the hydraulic rod 20 inside it, thereby pushing the filter plate 17 to slide inside the chute 16, making each filter plate 17 tightly connected in sequence, and then the pressure filtration process is carried out. At the same time, the limit cap 13 is pulled to extract the insertion rod 12 from the positioning hole 15, thereby releasing the fixation of the moving frame 10. With the cooperation of the limit block 9, the moving frame 10 is pushed to slide inside the limit groove 8 to the selected positioning hole 15 position, and then the limit cap 13 is released. Under the action of the elastic force of the spring 14, the insertion rod 12 is pulled to re-insert into the positioning hole 15 to fix the position of the moving frame 10. At this time, the moving frame 10 pulls out the water blocking cloth 7 from the roller 5. At this time, the water blocking cloth 7 drives the roller 5 and the turntable 4 to rotate, thereby tightening the torsion spring 6. At the same time, the water blocking cloth 7 covers both sides of the frame 1, which can prevent the filtrate from splashing out during the filtration process. After the pressure filtration process is completed, similarly, the limit cap 13 is pulled to extract the insertion rod 12, and the moving frame 10 is reset. At this time, the torsion spring 6 drives the turntable 4 and the roller 5 to reverse by its own elastic force to roll up the water blocking cloth 7, which is convenient for cleaning the solid impurities inside the filter plate 17, solving the problem that the existing water blocking structure is large in volume and affects the subsequent cleaning and maintenance of the equipment.
