Description
Technical Field
[0001] This utility model relates to the field of filter press technology, and in particular to a filter press unloading device. Background Technology
[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device, applied in chemical production as early as the 18th century, and still widely used in industries such as chemicals, pharmaceuticals, metallurgy, dyes, food, brewing, ceramics, and environmental protection. When unloading the filter press after filtration, the filter cake relies entirely on its own weight. However, the filter cake itself has a certain stickiness and often adheres to the filter plates, making it difficult to unload, resulting in incomplete unloading. Utility Model Content

[0025] like Figure 1-9 As shown, a filter press unloading device includes a lifting mechanism 2 disposed above the filter press 1. A moving mechanism 3 is installed on the lifting mechanism 2, which can move along the direction of the filter plate opening. A cleaning mechanism 4 for cleaning the sides of the filter plate is installed at the lower part of the moving mechanism 3. A plate pulling trolley mechanism 5 for pulling the filter plate open one by one is installed on the front and rear sides of the filter press 1. The filter press 1 is an existing plate filter press, which is prior art, and its specific structure will not be described in detail here.
[0026] like Figure 3-4As shown, the lifting mechanism 2 includes vertical supports 2-1 disposed on the left and right sides of the filter press 1. A horizontal support 2-2 is connected to the top surface of the two vertical supports 2-1. A rotating shaft 2-4 is rotatably mounted below the horizontal support 2-2 via bearings. A first driving component 2-3 for driving the rotating shaft 2-4 is mounted above the horizontal support 2-2. The first driving component 2-3 is a motor. The first driving component 2-3 is connected to the rotating shaft 2-4 via a transmission assembly 2-5. The transmission assembly 2-5 can be a sprocket, chain drive, or pulley, synchronous belt drive. Screws 2-6 are rotatably mounted on opposite sides of the frame 2-1. A movable seat 2-7 is threaded onto the screw 2-6. A lifting plate 2-8 is connected to the opposite surfaces of the two movable seats 2-7. A slide rail 2-11 is mounted on opposite sides of the two vertical supports 2-1. A slider 2-12 matching the slide rail 2-11 is mounted on the lifting plate 2-8. The moving mechanism 3 is installed between the two lifting plates 2-8. A second bevel gear 2-10 is mounted on the top of the screw 2-6. A first bevel gear 2-9 meshing with the second bevel gear 2-10 is mounted on both ends of the rotating shaft 2-4.
[0027] In use, the first drive component 2-3 is activated, and the first drive component 2-3 drives the rotating shaft 2-4 to rotate through the transmission component 2-5. The rotation of the rotating shaft 2-4 drives the first bevel gear 2-9 at both ends to rotate. The rotation of the first bevel gear 2-9 drives the second bevel gear 2-10 to rotate. The rotation of the second bevel gear 2-10 drives the lead screw 2-6 to rotate. The rotation of the lead screw 2-6 drives the moving seat 2-7 to rise or fall, thereby driving the lifting plate 2-8 to rise or fall, and in turn driving the moving mechanism 3 to rise or fall.
[0028] like Figure 5 As shown, the moving mechanism 3 includes two support frames 3-1 arranged side by side. The two ends of the support frames 3-1 are respectively connected to the two lifting plates 2-8. A rack 3-2 is installed on the top surface of the support frame 3-1. A moving frame 3-3 is arranged between the two support frames 3-1. Gears 3-6 that mesh with the rack 3-2 are installed on both the front and rear sides of the moving frame 3-3. The four gears 3-6 are divided into two groups, left and right. A second driving member 3-4 is arranged between the two gears 3-6 on the left side. The second driving member 3-4 is a motor. The second driving member 3-4 is connected to the central shaft of the two gears 3-6 through a reversing box 3-5. The two gears 3-6 on the right side are connected by a connecting shaft. The cleaning mechanism 4 is installed below the moving frame 3-3. The reversing box 3-5 is prior art and can be obtained by purchasing. Its specific structure will not be described here.
[0029] When in use, the second drive unit 3-4 is activated. The second drive unit 3-4 drives the two gears 3-6 located on the left side to rotate through the reversing box 3-5. Since the gears 3-6 mesh with the rack 3-2, the rotation of the gears 3-6 drives the moving frame 3-3 to move.
[0030] like Figure 6-7 As shown, the cleaning mechanism 4 includes a fixed frame 4-1, which is connected to the movable frame 3-3 via a connecting rod. A water pipe 4-2 is installed inside the fixed frame 4-1, and a mounting frame 4-3 is connected to the bottom of the fixed frame 4-1. Several nozzles 4-4 are installed inside the mounting frame 4-3. Channels for the filter plate to pass through are provided on the front and rear sides of the mounting frame 4-3. One end of the water pipe 4-2 is connected to an external water source via a flexible hose, and the other end of the water pipe 4-2 is connected to several nozzles 4-4. Specifically, the water pipe 4-2 includes three parts: a rectangular pipe at the top, a connector for connecting to a flexible hose on one side of the rectangular pipe, several vertical pipes connected to the bottom of the rectangular pipe, and a horizontal pipe installed on the outside of the mounting frame 4-3 via clamps. The horizontal pipe is connected to the vertical pipes and also to several nozzles 4-4.
[0031] like Figure 8-9 As shown, the plate-pulling trolley mechanism 5 includes a trolley body 5-1, with chains 5-2 connected to both the left and right sides of the trolley body 5-1. The filter press 1 is equipped with multiple sprockets 5-3 that mesh with the chains 5-2. The central shaft of one of the sprockets 5-3 is connected to the output end of the fourth driving component. The number and positional relationship of the sprockets 5-3 can be selected according to actual needs. Figure 8 Only one possible arrangement is shown in the figure; the fourth drive component is a motor, and the connection between the motor and the sprocket 5-3 is existing technology, which will not be described in detail here.
[0032] Specifically, the trolley body 5-1 includes a frame 5-1-1, both the left and right sides of the frame 5-1-1 are connected to the chain 5-2, and a first clamping claw 5-1-2 and a second clamping claw 5-1-3 are hinged inside the frame 5-1-1. A first spring 5-1-4 is vertically connected below the first clamping claw 5-1-2, and a second spring 5-1-5 is horizontally connected to the side of the second clamping claw 5-1-3 facing the first clamping claw 5-1-2. A third driving component 5-1-6 is installed below the first clamping claw 5-1-2, and the third driving component 5-1-6 is an electric push rod or a cylinder, etc.
[0033] In use, the fourth drive component drives the sprocket 5-3 to rotate, thereby driving the chain 5-2 to move. The movement of the chain 5-2 drives the trolley body 5-1 to move. When the trolley body 5-1 moves to the filter plate, the third drive component 5-1-6 pushes the second clamping claw 5-1-3 to rotate counterclockwise around its hinge axis. The pull rod of the filter plate enters between the first clamping claw 5-1-2 and the second clamping claw 5-1-3 from the top of the second clamping claw 5-1-3. The first clamping claw 5-1-2 and the second clamping claw 5-1-3 clamp the pull rod of the filter plate. Then, as the chain 5-2 moves, the filter plate is pulled apart. The filter plates can be pulled apart one by one using the pull plate trolley mechanism 5.
[0034] The working process of this utility model is as follows:
[0035] First, the filter plates are pulled apart using the plate-pulling trolley mechanism 5. Then, the moving mechanism 3 moves the cleaning mechanism 4 above the filter plate. Subsequently, the lifting mechanism 2 lowers the moving mechanism 3 and the cleaning mechanism 4. When the cleaning mechanism 4 descends to the filter plate, the nozzles 4-4 on both sides spray high-pressure water onto both sides of the filter plate to clean it. The lifting mechanism 2 moves the nozzles 4-4 from top to bottom to rinse both sides of the filter plate from top to bottom. After one filter plate is cleaned, the lifting mechanism 2 raises the moving mechanism 3 and the cleaning mechanism 4, and the plate-pulling trolley mechanism 5 pulls apart the next filter plate. The moving mechanism 3 moves the cleaning mechanism 4 above the filter plate to continue cleaning. This process is repeated until all the filter plates are cleaned.
