Description

Technical Field

[0001] This utility model relates to the field of plate and frame filter press technology, specifically a plate and frame filter press. Background Technology

[0002] Plate and frame filter presses were the first machines used in chemical dewatering. Although plate and frame filter presses are generally operated intermittently, require large investments in infrastructure and equipment, and have relatively low filtration capacity, they are still widely used in some small wastewater treatment plants due to their advantages such as high filtration driving force, high solids content in the filter cake, clear filtrate, high solids recovery rate, and low consumption of conditioning chemicals.

[0003] Existing plate and frame filter presses typically require individual cleaning of each filter plate during use, which necessitates moving and separating the filter plates one by one, a process that is time-consuming. Therefore, this does not meet current requirements, and we have proposed a new plate and frame filter press to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a plate and frame filter press to solve the problems mentioned in the background art, such as the need to clean each filter plate individually during use, which requires moving and separating the filter plates one by one, resulting in a long time consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plate and frame filter press, including a fixed platform, a push rod movably mounted on one side of the fixed platform, a pressure plate fixedly mounted at the end of the push rod, a plurality of horizontally arranged plate and frame filter plates movably mounted on the surface of the pressure plate, a fixed plate movably mounted on the front side of the foremost plate and frame filter plate, a bracket fixedly connected between the fixed plate and the fixed platform, and diagonal braces fixedly mounted on both sides of the plate and frame filter plate near the top, a connecting chain movably connecting every two adjacent diagonal braces, and an L-shaped movable rod movably mounted between every two diagonal braces.

[0006] Preferably, a small jack is fixedly installed at the bottom end of each L-shaped movable rod, and a plug rod is fixedly connected to the output end of the small jack. The output end of the small jack is in contact with the surface of the connecting chain, and the plug rod extends through the interior of the connecting chain to the bottom of the connecting chain. An oil inlet is provided on the outer side of the L-shaped movable rod, and the oil inlet is connected to the interior of the plug rod.

[0007] Preferably, a hydraulic cylinder is fixedly installed inside the fixed platform, the output end of the hydraulic cylinder is fixedly connected to the push rod, a support frame is fixedly installed at the bottom of the fixed platform, a water inlet pipe is provided on the outside of the fixed plate, and a base plate is fixedly installed at the bottom of the support frame.

[0008] Preferably, a connecting plate is fixedly installed on the outer side of the support frame, and a drain pipe is provided inside the connecting plate. Drainage branch pipes are fixedly installed on both sides of the plate frame filter plate near the bottom end, and a water inlet groove is provided on the top surface of the drain pipe.

[0009] Preferably, the plate and frame filter plate has a water inlet inside, and the water inlets are connected in a continuous manner.

[0010] Preferably, each bracket has a sliding groove at its top, the bottom of each L-shaped movable rod is slidably inserted into the sliding groove, and each L-shaped movable rod has a pulley movably installed at its bottom.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the cooperation of the diagonal bracing frame and the connecting chain, enables the device to clean the mud cake on the surface of the plate and frame filter plate when it is necessary to clean it. By pulling the last plate and frame filter plate, the plate and frame filter plate will be moved backward by the connection of the diagonal bracing frame and the connecting chain. This allows pulling one plate and frame filter plate to move all the plate and frame filter plates, making it convenient to clean the mud cake on the surface of each plate and frame filter plate and reducing the time required to pull the plate and frame filter plate each time. 2. This utility model utilizes the cooperation of an L-shaped movable rod and a plug rod. When the device is in use, the output end can be pushed out by the plug rod, thereby pressing the connecting chain downwards. This pushes the two plate and frame filter plates to press tightly against each other, achieving a tight seal between each pair of plate and frame filter plates. When it is necessary to move the plate and frame filter plates, the output end of the plug rod can be retracted first. At this time, the plug rod no longer presses against the connecting chain. When the plate and frame filter plates move, it will push the L-shaped movable rod to move simultaneously, avoiding the need to realign the plug rod and connecting chain. Attached Figure Description

[0014] 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.

[0015] Please see Figures 1 to 5 An embodiment of this utility model provides a plate and frame filter press, including a fixed platform 1. A push rod 2 is movably installed on one side of the fixed platform 1. A pressure plate 3 is fixedly installed at the end of the push rod 2. Multiple horizontally arranged plate and frame filter plates 4 are movably installed on the surface of the pressure plate 3. A fixed plate 5 is movably installed on the front side of the foremost plate and frame filter plate 4. A bracket 6 is fixedly connected between the fixed plate 5 and the fixed platform 1. Diagonal braces 14 are fixedly installed on both sides of the plate and frame filter plate 4 near the top. A connecting chain 20 is movably connected between every two adjacent diagonal braces 14. An L-shaped movable rod 15 is movably installed between every two diagonal braces 14.

[0016] With the cooperation of the diagonal brace 14 and the connecting chain 20, when the mud cake on the surface of the plate and frame filter plate 4 needs to be cleaned during use, the last plate and frame filter plate 4 can be pulled. At this time, the plate and frame filter plate 4 will be pulled to the rearward by the connection of the diagonal brace 14 and the connecting chain 20. Thus, pulling one plate and frame filter plate 4 will drive all plate and frame filter plates 4 to move, which facilitates the cleaning of the mud cake on the surface of each plate and frame filter plate 4 and reduces the time of pulling the plate and frame filter plate 4 each time.

[0017] The bottom of the L-shaped movable rod 15 is fixedly equipped with a small jack 18. The output end of the small jack 18 is fixedly connected to a plug rod 19. The output end of the small jack 18 is in contact with the surface of the connecting chain 20. The plug rod 19 extends through the interior of the connecting chain 20 to the bottom of the connecting chain 20. The outside of the L-shaped movable rod 15 is provided with an oil inlet 21, which is connected to the interior of the plug rod 19.

[0018] With the cooperation of the L-shaped movable rod 15 and the insertion rod 19, when the device is in use, the output end can be pushed out by the insertion rod 19, thereby pressing the connecting chain 20 downward, which in turn pushes the two plate and frame filter plates 4 to stick together tightly, achieving a tight seal between each pair of plate and frame filter plates 4. When it is necessary to move the plate and frame filter plates 4, the output end of the insertion rod 19 can be retracted first. At this time, the insertion rod 19 no longer presses the connecting chain 20. When the plate and frame filter plates 4 move, it will push the L-shaped movable rod 15 to move at the same time, avoiding the need to realign the insertion rod 19 and the connecting chain 20.

[0019] A hydraulic cylinder 16 is fixedly installed inside the fixed platform 1. The output end of the hydraulic cylinder 16 is fixedly connected to the push rod 2. A support frame 8 is fixedly installed at the bottom of the fixed platform 1. A water inlet pipe 7 is provided on the outside of the fixed plate 5. A base plate 9 is fixedly installed at the bottom of the support frame 8.

[0020] A connecting plate 10 is fixedly installed on the outside of the support frame 8. A drain pipe 11 is provided inside the connecting plate 10. Drainage branch pipes 13 are fixedly installed on both sides of the plate and frame filter plate 4 near the bottom. A water inlet groove 12 is provided on the top surface of the drain pipe 11.

[0021] The plate and frame filter plate 4 has a water inlet 17 inside, and the water inlets 17 are connected to each other.

[0022] The top of each bracket 6 is provided with a sliding groove 23, and the bottom of each L-shaped movable rod 15 is slidably inserted into the sliding groove 23. Each L-shaped movable rod 15 is movably equipped with a pulley 22.

[0023] When the plate and frame filter press is in use, if it is necessary to clean the mud cake on the surface of the plate and frame filter plate 4, the last plate and frame filter plate 4 can be pulled. At this time, the plate and frame filter plate 4 will be pulled to the rearward side through the connection of the inclined support frame 14 and the connecting chain 20. Thus, pulling one plate and frame filter plate 4 will drive all plate and frame filter plates 4 to move, which facilitates the cleaning of the mud cake on the surface of each plate and frame filter plate 4 and reduces the time of pulling the plate and frame filter plate 4 each time.

[0024] The output end can be pushed out by inserting rod 19, thereby pressing the connecting chain 20 downward, which in turn pushes the two plate and frame filter plates 4 to stick together tightly, achieving a tight seal between each pair of plate and frame filter plates 4. When it is necessary to move the plate and frame filter plates 4, the output end of inserting rod 19 can be retracted first. At this time, inserting rod 19 no longer presses the connecting chain 20. When the plate and frame filter plates 4 move, it will push the L-shaped movable rod 15 to move at the same time, avoiding the need to realign inserting rod 19 and connecting chain 20.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
