Technical Field

[0001] This utility model relates to the field of plate and frame filter press technology, and in particular to an auxiliary water receiving device for a plate and frame filter press. Background Technology

[0002] Plate and frame filter presses are intermittent pressure filtration devices widely used in industrial production, primarily for solid-liquid separation. They are particularly suitable for filtering various suspensions with high viscosity, fine particles, and high compressibility.

[0003] Existing plate and frame filter presses may experience filtrate dripping during feeding and filtration. If the filter cloth is damaged, there will be a continuous and large amount of dripping. However, existing plate and frame filter presses do not have an effective structure designed to address this situation and do not meet the needs of operators.

[0004] Therefore, we propose an auxiliary water receiving device for plate and frame filter presses to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary water receiving device for a plate and frame filter press.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary water receiving device for a plate and frame filter press includes a plate and frame filter press body and a pressing plate. A transmission device is provided at the front end of the plate and frame filter press body. The transmission device includes a first sealing cavity and a second sealing cavity fixedly connected to the front end of the plate and frame filter press body. The first sealing cavity and the second sealing cavity are connected via a water supply pipe. A piston plate is slidably connected inside the first sealing cavity. An L-shaped rod is fixedly connected to the right end of the piston plate and is fixedly connected to the pressing plate. A piston block is slidably connected inside the second sealing cavity. A sliding rod is fixedly connected to the right end of the piston block. The end of the sliding rod away from the piston block slides through the second sealing cavity and extends outside the second sealing cavity. A spring is fixedly connected to the inner wall of the second sealing cavity and the right end of the piston block. The plate and frame filter press body is provided with the auxiliary water receiving device.

[0007] Preferably, the auxiliary water receiving device includes a rectangular plate fixedly connected to the lower end of the plate and frame filter press body, a rectangular groove is provided on the rectangular plate, a rectangular block is slidably connected in the rectangular groove, a connecting rod is fixedly connected to the front end of the rectangular block, and the connecting rod is fixedly connected to the sliding rod.

[0008] Preferably, a telescopic plate is fixedly connected to the left end of the plate and frame filter press body, and a fixed block is fixedly connected to the rear end of the plate and frame filter press body. A sliding groove is provided on the fixed block, and a slider is slidably connected in the sliding groove. The rectangular block and the slider are together fixedly connected to the telescopic plate.

[0009] Preferably, a water collection tank is fixedly connected to the lower end of the plate and frame filter press body, and a drain pipe is fixedly connected to the left end of the water collection tank.

[0010] Preferably, the telescopic plate has multiple drainage holes, and the multiple drainage holes are located directly above the water collection tank.

[0011] Preferably, a collection bucket is provided at the lower end of the drain pipe.

[0012] Compared with existing technologies, the advantages of this device are: 1. The pressing plate of the plate and frame filter press moves to the left, which in turn drives the L-shaped rod to push the piston plate to squeeze the hydraulic oil in the first sealing chamber, so that it enters the second sealing chamber through the water supply pipe, and squeezes the piston block and slide rod to the right. At this time, the spring is in a compressed state, and then drives the connecting rod and auxiliary water receiving device to move to the right.

[0013] 2. During the feeding and filtration process of the plate and frame filter press, the filtrate dripping will fall onto the telescopic plate, fall into the water collection tank through the drain hole, and then flow into the collection bucket through the drain pipe for centralized collection.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-5An auxiliary water receiving device for a plate and frame filter press includes a plate and frame filter press body 1 and a pressing plate 7. A transmission device is provided at the front end of the plate and frame filter press body 1. The transmission device includes a first sealing cavity 2 and a second sealing cavity 3 fixedly connected to the front end of the plate and frame filter press body 1. The first sealing cavity 2 and the second sealing cavity 3 are connected by a water supply pipe 4. A piston plate 5 is slidably connected in the first sealing cavity 2. An L-shaped rod 6 is fixedly connected to the right end of the piston plate 5. The L-shaped rod 6 is fixedly connected to the pressing plate 7. A piston block 8 is slidably connected in the second sealing cavity 3. A sliding rod 9 is fixedly connected to the right end of the piston block 8. The end of the sliding rod 9 away from the piston block 8 slides through the second sealing cavity 3 and extends to the outside of the second sealing cavity 3. A spring 10 is fixedly connected to the inner wall of the second sealing cavity 3 and the right end of the piston block 8. The second sealing cavity 3 is narrower and longer than the first sealing cavity 2. The spring 10 has sufficient room for movement and will not exceed its elastic limit when squeezed. The first sealing chamber 2 is filled with a sufficient amount of hydraulic oil. When the pressing plate 7 completes the filter plate pressing work, the transmission device can move the telescopic plate 14 to the bottom of the rightmost filter plate, effectively collecting the dripping filtrate. After the filtration work is completed, the pressing plate 7 resets, and the transmission device also resets. At this time, the first sealing chamber 2 is under negative pressure, and the hydraulic oil flows back into the first sealing chamber 2 under the pressure. At this time, only a small amount of hydraulic oil remains in the second sealing chamber, and the piston block 8 is no longer pressed. The piston block 8 moves to the left and resets under the action of the spring 10, which in turn drives the telescopic plate 14 to move to the left, preventing material from falling onto the telescopic plate 14. The plate and frame filter press body 1 is equipped with an auxiliary water receiving device. A water collection tank 16 is fixedly connected to the lower end of the plate and frame filter press body 1, and a drain pipe 17 is fixedly connected to the left end of the water collection tank 16. A collection bucket is provided at the lower end of the drain pipe 17.

[0018] The auxiliary water receiving device includes a rectangular plate 11 fixedly connected to the lower end of the plate and frame filter press body 1. A rectangular groove is provided on the rectangular plate 11, and a rectangular block 12 is slidably connected in the rectangular groove. A connecting rod 13 is fixedly connected to the front end of the rectangular block 12. The connecting rod 13 is fixedly connected to the slide rod 9 and is Z-shaped.

[0019] A telescopic plate 14 is fixedly connected to the left end of the plate and frame filter press body 1, and a fixing block 15 is fixedly connected to the rear end of the plate and frame filter press body 1. A sliding groove is provided on the fixing block 15, and a slider is slidably connected in the sliding groove. The telescopic plate 14 is fixedly connected to the rectangular block 12 and the slider. Multiple drainage holes are provided on the telescopic plate 14, and the multiple drainage holes are located directly above the water collection tank 16.

[0020] 3. When using this utility model, the operator moves the pressing plate 7 of the plate and frame filter press 1 to the left, which in turn drives the L-shaped rod 6 to push the piston plate 5 to squeeze the hydraulic oil in the first sealing chamber 2, allowing it to enter the second sealing chamber 3 through the water supply pipe 4. This squeezes the piston block 8 and the sliding rod 9 to the right, at which point the spring 10 is compressed. Then, the connecting rod 13 and the auxiliary water receiving device move to the right to below the rightmost filter plate, effectively collecting the dripping filtrate. After the filtration is completed, the pressing plate 7 resets, and the transmission device also resets. At this time, the first sealing chamber 2 is under negative pressure, and the hydraulic oil flows back into the first sealing chamber 2 under the action of pressure. At this time, there is only a small amount of hydraulic oil in the second sealing chamber, and the piston block 8 is no longer squeezed. The piston block 8 moves to the left and resets under the action of the spring force of the spring 10, which in turn drives the telescopic plate 14 to move to the left, so that the material will not fall onto the telescopic plate 14. The filtrate dripping during the feeding and filtration process of the plate and frame filter press 1 will fall onto the telescopic plate 14, fall into the water collection tank 16 through the drain hole, and then flow into the collection bucket through the drain pipe 17 for centralized collection.
