Description

Technical Field

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

[0002] In chemical production processes, such as the production of butyl black powder, a large amount of wastewater and waste gas are generated. The wastewater contains solid pollutants and needs to be separated into solid and liquid by a filter press. Existing filter presses still have room for improvement in terms of processing efficiency and environmental performance. A filter press is a machine that applies mechanical force to one side of the filter medium to achieve filtration. It is mainly used for solid-liquid separation of sludge (water).

[0003] A search revealed Chinese Patent Publication No. CN219630698U, which discloses a sludge filter press. This press uses a hydraulic pipeline to divert high-pressure liquid, providing power to the separation device, thus improving energy utilization and reducing costs. The separation device quickly separates the filter plates, shortening sludge discharge time and increasing efficiency. A vibration device drives the filter plates to vibrate, causing sludge to fall off quickly. A washing device then quickly cleans the filter plates, reducing operator workload and improving practicality. The press includes a filter press body, filter plates, a sliding device, and a turning device. The sliding and turning devices are mounted on the filter press body, and the filter plates are mounted on the sliding device. It also includes a filter pressing device, hydraulic pipeline, separation device, vibration device, and washing device. However, in this invention, the vibration motor drives the diaphragm filter plates to vibrate via a trapezoidal plate, shaking off all the sludge. However, the vibration of the trapezoidal plate impacts the diaphragm filter plates, reducing their lifespan and leading to higher maintenance costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sludge filter press with advantages such as high filter cake cleaning efficiency. It solves the problem that while a vibrating motor drives a diaphragm filter plate to vibrate through a trapezoidal plate to shake off all the sludge from the diaphragm filter plate, the vibration of the trapezoidal plate will impact the diaphragm filter plate, thereby reducing the service life of the diaphragm filter plate and leading to high maintenance costs.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 The sludge filter press in this embodiment includes a support frame 1. Support plates 2 are fixed at both ends of the upper surface of the support frame 1. Connecting frames 3 are provided on the front and rear sides between the opposite sides of the two support plates 2. Several filter plates 4 are slidably connected to the opposite sides of the two connecting frames 3. A first electric push rod 5 is provided on the left side of the left support plate 2. A pressure plate 6 is fixed to the output shaft of the first electric push rod 5. A separation mechanism 7 for separating the filter cake and the filter plates 4 is provided on the left side of the left support plate 2. A collection and cleaning mechanism 8 for collecting and cleaning the filter cake is provided at the bottom of the left side of the left support plate 2.

[0030] In this embodiment, each of the two connecting frames 3 has a sliding groove on one side opposite to the other. The front and rear sides of the pressure plate 6 are fixed with sliders. The sliders move horizontally in the inner cavity of the sliding groove. The cross-sectional shape of the support plate 2 is U-shaped, and the inner top wall of the support plate 2 has a through hole.

[0031] Understandably, by extending the piston rod of the first electric push rod 5 to the right, the pressure plate 6 moves to the right, thereby squeezing the multiple filter plates 4, which can filter out the filter cake and mud water in the sludge. Then, compressed air can be sprayed onto the filter plates 4 by the air compressor, thereby improving the cleaning effect of the filter plates 4.

[0032] Please see Figures 2 to 3To clean the filter cake on the surface of the filter plate 4, the separation mechanism 7 in this embodiment includes two drive motors 71, two rotating rods 72, two cams 73, two sliding plates 74, several fixed columns 75, threaded rods 76, and several telescopic rods 77. The drive motors 71 are fixed on opposite sides of the two support plates 2. The rotating rods 72 are rotatably connected between opposite sides of the left and right side walls of the inner cavity of the support plate 2 via bearings. The output shaft of the drive motors 71 passes through the support plate 2 and extends into the inner cavity of the support plate 2 and is fixed to the rotating rods 72. The cams 73 are fixed on the outer surface of the rotating rods 72. A fixing groove is provided on the upper surface of the support plate 2, and the sliding plates 74 are disposed in the fixing groove. The drive motor 71 is started, and the output shaft of the drive motor 71 rotates, which drives the rotating rod 72 to rotate. The rotation of the rotating rod 72 causes the cam 73 fixed on its surface to rotate. When the cam 73 rotates upward, it can lift the sliding plate 74, so that the sliding plate 74 moves up and down in the inner cavity of the fixed groove. Thus, multiple filter plates 4 can be moved up and down through the connecting frame 3, and the filter cake on the surface of the filter plate 4 can fall into the inner cavity of the collection box 82. Several fixed posts 75 are threadedly connected to the upper surface of the pressure plate 6 and the filter plate 4. The threaded rod 76 is rotatably connected to the right side of the fixed post 75 on the upper surface of the pressure plate 6 through the bearing. Several telescopic rods 77 are fixed between the opposite sides of the two filter plates 4.

[0033] It is understandable that by pulling the leftmost filter plate 4 to the left, the multiple filter plates 4 can be separated by a distance through the telescopic rod 77. Then, the threaded rod 76 on the right side of the fixing post 75 on the upper surface of the pressure plate 6 can be screwed into the threaded groove on the left side of the fixing post 75 on the upper surface of the leftmost filter plate 4, so as to fix the pressure plate 6 and the filter plate 4, thereby preventing the multiple filter plates 4 from sticking together again.

[0034] In this embodiment, the connecting frame 3 is fixed between the opposite sides of the left and right sliding plates 74, the cam 73 rotates in the inner cavity of the support plate 2, the first electric push rod 5 is fixed to the sliding plate 74 and its piston rod passes through the sliding plate 74 and extends to the right side of the sliding plate 74.

[0035] Among them, guide grooves are provided on the opposite sides of the front and rear side walls of the inner cavity of the support plate 2, and guide blocks are fixed on the front and rear sides of the sliding plate 74. The guide blocks move linearly up and down in the inner cavity of the guide groove. A threaded groove is provided on the left side of the fixed column 75 on the upper surface of the leftmost filter plate 4. The inner diameter of the threaded groove is adapted to the outer diameter of the threaded rod 76.

[0036] It should be noted that by setting up the drive motor 71, the rotating rod 72 and the cam 73, the sliding plate 74 can move up and down reciprocally, so that the filter cake adhering to the filter plate 4 can fall off the surface of the filter plate 4, thereby improving the cleaning efficiency of the filter cake.

[0037] Please see Figure 4To facilitate filter cake cleaning, the collection and cleaning mechanism 8 in this embodiment includes a second electric push rod 81, a collection box 82, a push plate 83, and a shovel block 84. The second electric push rod 81 is fixed to the left side of the collection box 82, which is fixed at the bottom between the two support plates 2 on opposite sides. The collection box 82 can collect the filter cake. The piston rod of the second electric push rod 81 passes through the collection box 82 and extends into the inner cavity of the collection box 82 and is fixed to the push plate 83. When the second electric push rod 81 is activated, the piston rod of the second electric push rod 81 moves to the right, which can push the push plate 83 to the right. The movement of the push plate 83 can push the filter cake to the right. The shovel block 84 is fixed at the bottom right side of the push plate 83. The shovel block 84 can shovel the filter cake adhering to the bottom wall of the collection box 82.

[0038] In this embodiment, the collection box 82 is a cuboid with a hollow interior and a missing upper surface. The shovel block 84 has a triangular cross-sectional shape. The right side of the collection box 82 is hinged to a door via a door hinge, and a sealing ring is fixed to the left side of the door.

[0039] It should be noted that the No. 2 electric push rod 81, push plate 83 and shovel block 84 make it easier for workers to clean the filter cake, greatly reducing the labor intensity of workers and making the cleaning efficiency higher.

[0040] The working principle of the above embodiments is as follows:

[0041] (1) The piston rod of the first electric push rod 5 can be extended to the right, causing the pressure plate 6 to move to the right, thereby squeezing the multiple filter plates 4, which can filter out the filter cake and mud water in the sludge. In order to facilitate the cleaning of the filter cake attached to the surface of the filter plate 4, the leftmost filter plate 4 can be pulled to the left. The telescopic rod 77 can be used to separate the multiple filter plates 4 by a certain distance. Then, the threaded rod 76 on the right side of the fixing post 75 on the upper surface of the pressure plate 6 can be screwed into the threaded groove on the left side of the fixing post 75 on the upper surface of the leftmost filter plate 4. The pressure plate 6 is fixed to the filter plate 4 to prevent multiple filter plates 4 from sticking together again. Then, the drive motor 71 is started. The output shaft of the drive motor 71 rotates, which drives the rotating rod 72 to rotate. The rotation of the rotating rod 72 causes the cam 73 fixed on its surface to rotate. When the cam 73 rotates upward, it can lift the sliding plate 74, so that the sliding plate 74 moves up and down in the inner cavity of the fixed groove. Thus, multiple filter plates 4 can be moved up and down through the connecting frame 3, and the filter cake on the surface of the filter plate 4 can fall into the inner cavity of the collection box 82.

[0042] (2) The filter cake can be collected by the collection box 82. In order to facilitate the cleaning of the filter cake by the staff, the box door can be opened. By starting the second electric push rod 81, the piston rod of the second electric push rod 81 moves to the right, which can push the push plate 83 to the right. The movement of the push plate 83 can push the filter cake to the right. The shovel block 84 can shovel the filter cake that is attached to the bottom wall of the collection box 82, thus making the cleaning efficiency high.
