Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of titanium dioxide production, and specifically discloses a quick cake unloading mechanism of a plate-and-frame filter press for titanium dioxide. BACKGROUND

[0002] In the production process of titanium dioxide, a plate-and-frame filter press is needed, which can remove solid particles in titanium dioxide slurry, ensure the purity of titanium dioxide, and improve the production quality of products. The plate-and-frame filter press for titanium dioxide production currently available on the market comprises filter plates, an extrusion structure, and a water conveying structure. In actual use, the extrusion structure drives multiple filter plates to abut against each other, and then the water conveying structure drives titanium dioxide slurry to be conveyed into a filter chamber composed of multiple filter plates, which can filter solid particles in the titanium dioxide slurry. However, although this plate-and-frame filter press can achieve good filtering effect on solid particles in titanium dioxide slurry, it still has some deficiencies in actual use, such as: When the filter chamber composed of multiple filter plates in the plate-and-frame filter press filters solid particles in titanium dioxide slurry, the solid particles will adhere to the filter cloth in the filter plates. After the filter plates filter the solid particles in the titanium dioxide slurry, the multiple filter plates in the filter chamber are usually disassembled one by one by a disassembly trolley on the filter press. When the filter plates are disassembled by the disassembly trolley, the disassembly trolley will shake the filter plates on the slide rails of the filter press, thereby achieving quick separation of filter cakes and filter cloths on the filter plates. However, although the disassembly trolley can separate and shake the filter plates to quickly separate the filter cakes and filter cloths, the shaking of the filter plates by the disassembly trolley can easily cause the separation of the filter cloths and filter plates, and the shaking of the filter plates can also cause residues in the filter cakes to fly everywhere, which can easily pollute the environment around the filter press and increase the workload of workers.

[0003] Therefore, we propose a quick cake unloading mechanism of a plate-and-frame filter press for titanium dioxide to solve the problems of easy separation of filter cloths and filter plates and flying of residues in filter cakes caused by the shaking of filter plates by a disassembly trolley.

[0006] In the above technical scheme, further, the side surfaces of the extrusion plates, the middle plate frames and the discharge plate frames are fixed with abutting sliding blocks, the abutting sliding blocks slide on the slide rail frame body, and the dismounting trolley shakes the discharge plate frames through the abutting sliding blocks.

[0007] In the above technical scheme, further, the water supply structure comprises a second fixed plate fixed on the sealing plate, the second fixed plate is distributed on the side of the sealing plate away from the extrusion plate, the middle parts of the middle plate frames and the discharge plate frames are provided with water inlet holes, the second fixed plate is fixed with a water delivery pipe, and the water delivery pipe and the water inlet holes are coaxially distributed.

[0008] In the above technical scheme, further, the slide rail frame body is fixed with supporting legs, the extrusion structure comprises a mounting plate fixed on the slide rail frame body, the side of the mounting plate close to the extrusion plate is fixed with an extrusion hydraulic cylinder, the output end of the extrusion hydraulic cylinder is fixed with a first fixed plate, and the first fixed plate is fixed on the extrusion plate.

[0009] In the above technical scheme, further, both sides of the middle plate frames and the discharge plate frames are fixed with sealing strips, the sealing strips on the middle plate frames and the sealing strips on the discharge plate frames abut, and the end surface areas of the middle plate frames and the discharge plate frames are the same.

[0010] In the above technical scheme, further, the inner walls of the middle plate frames and the discharge plate frames are fixed with abutting columns, the inner walls of the middle plate frames and the discharge plate frames are fixed with plug-in rings close to the four corner parts, the inner walls of the middle plate frames and the discharge plate frames are provided with drainage holes at lower parts, the part close to the plug-in ring on the discharge plate frame is provided with a sliding cavity, and the inner cavity of the sliding cavity and the inner cavity of the plug-in ring are communicated.

[0011] In the above technical solution, a support column is fixed near the abutment column of the filter plate, and each support column is distributed between two abutment columns. A snap-fit ​​column is fixed at the part of the filter plate opposite to the plug ring. The snap-fit ​​column is inserted into the inside of the plug ring. A sealing ring is fixed in the middle of the filter plate and is inserted into the inside of the water inlet hole.

[0012] In the above technical solution, further, sliding holes are provided on both sides of the discharge plate frame near the sliding cavity, a sliding plate slides inside the sliding hole, a sliding column is fixed on the outside of the sliding plate, an impact rod is fixed between the two sliding plates, and a return spring is fixed between the upper part of the sliding plate and the inner wall of the sliding hole.

[0013] In the above technical solution, the abutting post on the discharge plate frame is further provided with a cavity, the abutting post is elastic, an impact magnetic block is embedded in the cavity, a connecting spring is fixed between the impact magnetic block and the inner wall of the cavity, and magnetic strips are embedded on both sides of the sliding post, the magnetic poles of the magnetic strips and the magnetic poles of the impact magnetic block repel each other.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In the rapid cake discharge mechanism of this plate and frame filter press, each middle plate and frame is fixed with a rotating column. The rotating column has a first rotating plate and a second rotating plate. Two adjacent first rotating plates are rotatably connected, and two adjacent second rotating plates are rotatably connected. The first rotating plates and the second rotating plates do not contact the discharge plate and frame. When two adjacent middle plates and frames separate, the discharge plate and frame still exist between the two middle plates and frames. This can prevent the solid particles from splashing when the disassembly trolley shakes the discharge plate and frame by abutting the slider.

[0015] 2. When the filter plates in the quick cake discharge mechanism of this plate and frame filter press are installed inside the middle plate and frame, the sides of the filter plates and the end faces of the middle plate and frame are coplanar. This ensures that when the sealing strips on the middle plate and frame and the discharge plate and frame come into contact, the solid particles in the titanium dioxide slurry are mainly distributed inside the discharge plate and frame. This facilitates the separation of the filter cake composed of solid particles from the discharge plate and frame when the disassembly trolley shakes the discharge plate and frame by the contact slider. It also facilitates the cleaning of the filter plates inside the middle plate and frame by the subsequent workers, and avoids the splashing of solid particles discharged from the discharge plate and frame when the solid particles inside the discharge plate and frame separate.

[0016] 3. When the output end of the extrusion hydraulic cylinder in the rapid cake discharge mechanism of the plate and frame filter press extrudes the extrusion plate on the first fixed plate, the extrusion plate, the middle plate frame, the discharge plate frame and the sealing plate can form a sealed filter chamber structure. At this time, the first rotating plate and the second rotating plate can extrude the sliding column, and the sliding column can drive the sliding plate to extrude the return spring. At this time, the impact rod can move away from the locking column. Since the inner cavity of the sliding cavity and the inner cavity of the insertion ring are connected, the locking column can penetrate the insertion ring and be inserted into the interior of the sliding cavity. When the first rotating plate and the second rotating plate do not extrude the sliding column, the repulsive force generated by the return spring will drive the impact rod to impact the filter plate through the sliding plate, thereby realizing the rapid separation of solid particles on the filter plate.

[0017] 4. When the impact rod in the quick cake discharge mechanism of the plate and frame filter press slides inside the sliding chamber, the magnetic strip on the impact rod can provide repulsive force to the impact magnetic blocks at different positions on the discharge plate and frame. At this time, the impact magnetic blocks can impact the inner wall of the abutting column. The impact force generated by the impact magnetic blocks can be transmitted to the filter plate, which can realize the rapid separation of solid particles on the filter plate, making it convenient for subsequent workers to process the solid particles filtered by the filter plate.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0022] Example 1: Please refer to Figures 1-9 As shown, the present invention provides a technical solution: This invention relates to a rapid cake unloading mechanism for a plate and frame filter press for titanium dioxide, comprising a slide rail frame 1, on which extrusion plates 6 and sealing plates 62 are distributed, and a central plate frame 61 is distributed at equal intervals between the extrusion plates 6 and sealing plates 62. Discharge plate frames 63 are distributed on both sides of the central plate frame 61 on the slide rail frame 1. The extrusion plates 6, the central plate frame 61 and the discharge plate frames 63 all slide on the slide rail frame 1. A disassembly trolley 10, an extrusion structure and a water supply structure are connected to the slide rail frame 1.

[0023] A rotating column 72 is fixed to the side of each middle plate frame 61, and a rotating column 72 is also fixed to the side of the extrusion plate 6. Slide grooves 64 are provided on both sides of the sealing plate 62. A first rotating plate 7 and a second rotating plate 71 rotate on the rotating column 72. Two adjacent first rotating plates 7 are rotatably connected, and two adjacent second rotating plates 71 are rotatably connected. The first rotating plate 7 and the second rotating plate 71 located at the rear slide in the slide groove 64, and the first rotating plate 7 and the second rotating plate 71 located at the front rotate on the rotating column 72 on the side of the extrusion plate 6. Filter plates 65 are provided on the inner walls of the middle plate frame 61 and the discharge plate frame 63.

[0024] The sides of the extrusion plate 6, the middle plate frame 61 and the discharge plate frame 63 are all fixed with abutting sliders 68. The abutting sliders 68 slide on the slide rail frame 1. The disassembly trolley 10 shakes the discharge plate frame 63 through the abutting sliders 68. It should be noted that the disassembly trolley 10 and the abutting slider 68 are structures found in existing plate and frame filter presses. In actual use, the disassembly trolley 10 shakes the discharge plate and frame 63 through the abutting slider 68, thereby separating the solid particles in the titanium dioxide slurry from the discharge plate and frame 63. In actual use, the extrusion structure pushes the extrusion plate 6 and the discharge plate frame 63 to abut, and then the discharge plate frame 63 and the middle plate frame 61 abut. Since the discharge plate frame 63 is distributed on both sides of the middle plate frame 61, the discharge plate frame 63 can abut with the sealing plate 62. This can realize that the extrusion plate 6, the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62 form a sealed filter chamber structure. When the water supply structure delivers titanium dioxide slurry to the inside of the filter chamber structure, the filter plate 65 inside the middle plate frame 61 and the discharge plate frame 63 can filter the solid particles in the titanium dioxide slurry, which is convenient for the subsequent treatment of these solid particles. Since each middle plate frame 61 is fixed with a rotating column 72, and a first rotating plate 7 and a second rotating plate 71 rotate on the rotating column 72, two adjacent first rotating plates 7 are rotatably connected, and two adjacent second rotating plates 71 are rotatably connected. The first rotating plate 7 and the second rotating plate 71 do not contact the discharge plate frame 63. When two adjacent middle plate frames 61 are separated, the discharge plate frame 63 still exists between the two middle plate frames 61. This allows the disassembly trolley 10 to shake the discharge plate frame 63 by abutting the slider 68, thereby separating the solid particles in the titanium dioxide slurry from the discharge plate frame 63.

[0025] The water supply structure includes a second fixing plate 51 fixed on the sealing plate 62. The second fixing plate 51 is distributed on the side of the sealing plate 62 away from the extrusion plate 6. Water inlet holes 66 are opened in the middle of the middle plate frame 61 and the discharge plate frame 63. A water supply pipe 52 is fixed on the second fixing plate 51. The water supply pipe 52 and the water inlet hole 66 are coaxially distributed. The water inlet of the water pipe 52 is connected to an external pump. The external pump can drive the titanium dioxide slurry to be transported inside the filter chamber structure composed of the extrusion plate 6, the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62, thereby realizing the filtration treatment of solid particles in the titanium dioxide slurry.

[0026] The slide rail frame 1 is fixed with a support leg 2. The extrusion structure includes a mounting plate 3 fixed on the slide rail frame 1. A hydraulic cylinder 4 is fixed on the side of the mounting plate 3 near the extrusion plate 6. A first fixing plate 5 is fixed to the output end of the hydraulic cylinder 4. The first fixing plate 5 is fixed on the extrusion plate 6. When the output end of the hydraulic cylinder 4 presses the extrusion plate 6 on the first fixed plate 5, the extrusion plate 6, the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62 can form a sealed filter chamber structure, which can avoid gaps between the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62, and realize the filter chamber structure composed of the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62 to filter solid particles in titanium dioxide slurry.

[0027] Both sides of the middle plate frame 61 and the discharge plate frame 63 are fixed with sealing strips 67. The sealing strips 67 on the middle plate frame 61 and the sealing strips 67 on the discharge plate frame 63 abut against each other. The end face areas of the middle plate frame 61 and the discharge plate frame 63 are the same. The sealing strip 67 can seal the gap between the middle plate frame 61 and the discharge plate frame 63, preventing titanium dioxide slurry from flowing out from the gap between the middle plate frame 61 and the discharge plate frame 63; It should be noted that when the filter plate 65 is installed inside the middle plate frame 61, the side of the filter plate 65 and the end face of the middle plate frame 61 are coplanar. This allows the solid particles in the titanium dioxide slurry to be mainly distributed inside the discharge plate frame 63 when the sealing strip 67 on the middle plate frame 61 and the sealing strip 67 on the discharge plate frame 63 come into contact. This facilitates the separation of the filter cake composed of solid particles from the discharge plate frame 63 when the disassembly trolley 10 shakes the discharge plate frame 63 by the abutting slider 68. It also facilitates the subsequent cleaning of the filter plate 65 inside the middle plate frame 61 by the staff, and avoids the splashing of solid particles discharged from the discharge plate frame 63 when the solid particles inside the discharge plate frame 63 separate.

[0028] The inner walls of the middle plate frame 61 and the discharge plate frame 63 are both fixed with abutment posts 632. The inner walls of the middle plate frame 61 and the discharge plate frame 63 are fixed with insertion rings 634 near the four corners. The inner walls of the middle plate frame 61 and the discharge plate frame 63 are provided with drainage holes 633 at the bottom. The discharge plate frame 63 is provided with a sliding cavity 631 near the insertion ring 634. The inner cavity of the sliding cavity 631 is connected to the inner cavity of the insertion ring 634.

[0029] A support post 652 is fixed to the part of the filter plate 65 near the abutment post 632. Each support post 652 is distributed between two abutment posts 632. A snap-fit ​​post 653 is fixed to the part of the filter plate 65 opposite to the insertion ring 634. The snap-fit ​​post 653 is inserted into the inside of the insertion ring 634. A sealing ring 651 is fixed to the middle of the filter plate 65. The sealing ring 651 is inserted into the inside of the water inlet hole 66. When the snap-fit ​​post 653 is snapped into the inside of the plug ring 634, and the abutment post 632 and the support post 652 abut against the filter plate 65, there will be gaps between the filter plate 65 and the middle plate frame 61 and the discharge plate frame 63. This allows the water in the titanium dioxide slurry to pass through the filter plate 65 and enter the interior of the drain hole 633 when the filter plate 65 filters the solid particles in the titanium dioxide slurry, thereby achieving rapid discharge of the water in the solid particles.

[0030] Example 2: Please refer to Figures 1-9 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, when the first rotating plate 7 and the second rotating plate 71 do not press against the sliding column 8, the repulsive force generated by the reset spring 83 will drive the impact rod 81 to impact the filter plate 65 through the sliding piece 82, thereby realizing the rapid separation of solid particles on the filter plate 65.

[0031] The two sides of the discharge plate frame 63 are provided with sliding holes 69 near the sliding cavity 631. Sliding plates 82 slide inside the sliding holes 69. Sliding columns 8 are fixed on the outside of the sliding plates 82. Impact rods 81 are fixed between the two sliding plates 82. A return spring 83 is fixed between the upper part of the sliding plates 82 and the inner wall of the sliding holes 69. When the output end of the hydraulic cylinder 4 presses the pressing plate 6 on the first fixed plate 5, the pressing plate 6, the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62 can form a sealed filter chamber structure. At this time, the first rotating plate 7 and the second rotating plate 71 can press the sliding column 8. The sliding column 8 can drive the sliding piece 82 to press the return spring 83. At this time, the impact rod 81 can move away from the locking column 653. Since the inner cavity of the sliding cavity 631 and the inner cavity of the insertion ring 634 are connected, the locking column 653 can penetrate the insertion ring 634 and be inserted into the interior of the sliding cavity 631. When the first rotating plate 7 and the second rotating plate 71 do not press the sliding column 8, the repulsive force generated by the return spring 83 will drive the impact rod 81 to impact the filter plate 65 through the sliding piece 82, thereby realizing the rapid separation of solid particles on the filter plate 65.

[0032] The abutting post 632 on the discharge plate frame 63 has a cavity 9 inside. The abutting post 632 is elastic. An impact magnetic block 92 is embedded inside the cavity 9. A connecting spring 91 is fixed between the impact magnetic block 92 and the inner wall of the cavity 9. Magnetic strips 84 are embedded on both sides of the sliding post 8. The magnetic poles of the magnetic strips 84 and the magnetic poles of the impact magnetic block 92 repel each other. When the impact rod 81 slides inside the sliding cavity 631, the magnetic strip 84 on the impact rod 81 can provide repulsive force to the impact magnetic blocks 92 at different positions on the discharge plate frame 63. At this time, the impact magnetic blocks 92 can impact the inner wall of the abutting column 632. The impact force generated by the impact magnetic blocks 92 can be transmitted to the filter plate 65, which can realize the rapid separation of solid particles on the filter plate 65, making it convenient for subsequent workers to process the solid particles filtered by the filter plate 65. Working principle: In actual use, the extrusion structure pushes the extrusion plate 6 and the discharge plate frame 63 to abut, and then the discharge plate frame 63 abuts with the middle plate frame 61. Since the discharge plate frame 63 is distributed on both sides of the middle plate frame 61, the discharge plate frame 63 can abut with the sealing plate 62. This can realize that the extrusion plate 6, the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62 form a sealed filter chamber structure. When the water supply structure delivers titanium dioxide slurry to the inside of the filter chamber structure, the filter plate 65 inside the middle plate frame 61 and the discharge plate frame 63 can filter the solid particles in the titanium dioxide slurry, which is convenient for the subsequent treatment of these solid particles. Since each middle plate frame 61 is fixed with a rotating column 72, and a first rotating plate 7 and a second rotating plate 71 rotate on the rotating column 72, two adjacent first rotating plates 7 are rotatably connected, and two adjacent second rotating plates 71 are rotatably connected. The first rotating plate 7 and the second rotating plate 71 do not contact the discharge plate frame 63. When two adjacent middle plate frames 61 are separated, the discharge plate frame 63 still exists between the two middle plate frames 61. This allows the disassembly trolley 10 to shake the discharge plate frame 63 by abutting the slider 68, thereby separating the solid particles in the titanium dioxide slurry from the discharge plate frame 63. The water inlet of the water pipe 52 is connected to an external pump. The external pump can drive the titanium dioxide slurry to be transported inside the filter chamber structure composed of the extrusion plate 6, the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62, thereby realizing the filtration treatment of solid particles in the titanium dioxide slurry. When the output end of the extrusion hydraulic cylinder 4 extrudes the extrusion plate 6 on the first fixed plate 5, the extrusion plate 6, the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62 can form a sealed filter chamber structure, which can avoid gaps between the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62, and realize the filter chamber structure composed of the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62 to filter solid particles in titanium dioxide slurry; When the snap-fit ​​post 653 is snapped into the inside of the plug ring 634, and the abutment post 632 and the support post 652 abut against the filter plate 65, there will be gaps between the filter plate 65 and the middle plate frame 61 and the discharge plate frame 63. This allows the water in the titanium dioxide slurry to pass through the filter plate 65 and enter the interior of the drain hole 633 when the filter plate 65 filters the solid particles in the titanium dioxide slurry, thereby achieving rapid discharge of the water in the solid particles. When the output end of the hydraulic cylinder 4 presses the pressing plate 6 on the first fixed plate 5, the pressing plate 6, the middle plate frame 61, the discharge plate frame 63 and the sealing plate 62 can form a sealed filter chamber structure. At this time, the first rotating plate 7 and the second rotating plate 71 can press the sliding column 8. The sliding column 8 can drive the sliding piece 82 to press the return spring 83. At this time, the impact rod 81 can move away from the locking column 653. Since the inner cavity of the sliding cavity 631 and the inner cavity of the insertion ring 634 are connected, the locking column 653 can penetrate the insertion ring 634 and be inserted into the interior of the sliding cavity 631. When the first rotating plate 7 and the second rotating plate 71 do not press the sliding column 8, the repulsive force generated by the return spring 83 will drive the impact rod 81 to impact the filter plate 65 through the sliding piece 82, thereby realizing the rapid separation of solid particles on the filter plate 65. When the impact rod 81 slides inside the sliding cavity 631, the magnetic strip 84 on the impact rod 81 can provide repulsive force to the impact magnetic blocks 92 at different positions on the discharge plate frame 63. At this time, the impact magnetic blocks 92 can impact the inner wall of the abutting column 632. The impact force generated by the impact magnetic blocks 92 can be transmitted to the filter plate 65, which can realize the rapid separation of solid particles on the filter plate 65, making it convenient for subsequent workers to process the solid particles filtered by the filter plate 65.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
