Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm filter presses, in particular to a diaphragm filter press with high dehydration efficiency. Background Art

[0002] The diaphragm filter press is a highly efficient solid-liquid separation equipment, widely used in chemical, pharmaceutical, food, environmental protection and other fields. Its working principle is mainly based on pressure filtration, and solid-liquid separation is achieved through dynamic compression of the diaphragm. The diaphragm filter press consists of filter plates and diaphragms. A filter chamber is formed between the filter plates. The material to be processed is transported to the filter chamber. Under the action of pressure, solid particles are retained by the filter cloth, while the liquid flows out through the filter cloth. By piloting the diaphragm filter press, its performance and reliability under different working conditions can be evaluated.

[0003] During the pilot stage of the diaphragm filter press, the experimenters found that the filter cakes between the filter plates usually fell under the action of gravity after the filter plates were separated. Some filter cakes adsorbed on the surface of the filter plates needed to be manually broken apart by the experimenters to make them fall off. There were even some attachments left on the surface. If they were not cleaned, the diaphragm plates would be blocked and the filtering effect would be reduced, affecting the normal filtering work and resulting in reduced dehydration efficiency. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the above problems existing in the existing diaphragm filter press with high dehydration efficiency, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a diaphragm filter press with high dehydration efficiency, in order to solve the problem that "during the pilot stage of the diaphragm filter press, the experimenters found that the filter cakes between the filter plates usually fell under the action of gravity after the filter plates were separated, and some filter cakes adsorbed on the surface of the filter plates needed to be manually broken apart by the experimenters to make them fall off, and even some attachments would remain on the surface. If they were not cleaned, the diaphragm plates would be blocked and the filtering effect would be reduced, affecting the normal filtering work and resulting in reduced dehydration efficiency."

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A membrane filter press with high dehydration efficiency, comprising:

[0009] The main body unit includes a frame. Inside the frame, a pressing plate is movably connected. On one side of the pressing plate, a hydraulic press is provided and is fixedly connected to the frame. On the other side of the pressing plate, a thrust plate is provided and is fixedly connected to the frame. Between the pressing plate and the thrust plate, multiple groups of diaphragm filter plates are provided. On both sides of the diaphragm filter plates, fixed blocks are fixedly connected. On the upper surface of the frame, two movers are movably connected. On the upper side of the movers, a gripper is provided.

[0010] The cleaning unit includes side fixing plates fixedly connected to the two movers. Between the two side fixing plates, a top seat is detachably connected. Inside the top seat, a storage groove and a power groove are provided. Inside the power groove, a power component is provided. Inside the storage groove, two moving seats are movably connected. On the opposite sides of the moving seats, sliding grooves are provided. Inside the top seat, two bidirectional threaded rods are rotatably connected. At both ends of each bidirectional threaded rod, a threaded cylinder is threadedly connected. On the lower side of each group of threaded cylinders, a connecting rod is rotatably connected. On the lower surface of each connecting rod, a connecting block is rotatably connected. On one side of each group of connecting blocks, a sliding plate is fixedly connected. The surface of the sliding plate is slidably connected to the inner wall surface of the sliding groove. On the closer sides of the two moving seats, a scraping component is provided.

[0011] As a preferred solution of the diaphragm filter press with high dehydration efficiency described in the present utility model, wherein: on both inner wall surfaces of the two sides of the storage groove, two groups of limiting rods are fixedly connected. On both sides of the two moving seats, moving grooves matching the limiting rods are provided. On both side surfaces of each group of diaphragm filter plates, two groups of limiting grooves are provided. The inner wall surface of the limiting groove is slidably connected to the moving seat.

[0012] As a preferred solution of the diaphragm filter press with high dehydration efficiency described in the present utility model, wherein: the two groups of scraping components each include a cleaning plate closely attached to the inner wall surface of the moving seat. On the closer sides of the cleaning plates, a cross-sectional plate is fixedly connected. On both sides of the two cleaning plates, two groups of rotating shafts are fixedly connected. The rotating shafts are rotatably connected to the moving seat. On the surface of each group of rotating shafts, a torsion spring is sleeved. The two ends of the torsion spring are respectively fixedly connected to the moving seat and the cleaning plate.

[0013] As a preferred solution of the diaphragm filter press with high dehydration efficiency described in the present utility model, wherein: the length dimensions of the two cleaning plates are the same as the inner diameter dimensions of the moving seat. The length dimensions of the two cleaning plates are both smaller than the dimensions of the cross-sectional plate.

[0014] As a preferred solution of the diaphragm filter press with high dehydration efficiency described in the present utility model, wherein: the power component includes a motor fixedly connected to the top seat. The output end of the motor is fixedly connected to a worm. On the lower surface of the worm, two groups of worm wheels are meshed and connected. The two groups of worm wheels are fixedly connected to the two bidirectional threaded rods.

[0015] As a preferred solution of the diaphragm filter press with high dehydration efficiency described in the present utility model, wherein: clamping blocks are fixedly connected to the upper ends of the two side fixing plates, and bolts are threadedly connected to one sides of the clamping blocks. The two bolts are connected to the side fixing plates through threads, and the two clamping blocks are fixedly connected to the top seat on the side close to each other.

[0016] Advantages of the present utility model:

[0017] 1. Move the mover to both sides of the diaphragm filter plate, then clamp the fixing block through the gripper to drive the diaphragm filter plate to move. At the same time, start the motor to drive the worm to rotate forward. The worm gear meshed with the worm drives the bidirectional threaded rod to rotate. The threaded cylinder threadedly connected to the bidirectional threaded rod pushes the connecting rod to move, so that the connecting rod pushes the connecting block to move downward. Furthermore, the sliding plate fixedly connected to the connecting block slides inside the chute, driving the moving seat to move downward. At the same time, the limiting rod slides inside the moving groove. Then, the moving seat is slidably connected to the limiting groove to limit the moving direction of the moving seat. Then, the lower surface of the cross-sectional plate abuts against the upper surface of the diaphragm filter plate, so that the cleaning plate fixedly connected to the cross-sectional plate flips with the rotating shaft as the center, and the lower end of the cleaning plate contacts the filter cake. Through the push of the moving seat, the cleaning plate can scrape the filter cake from the surface of the diaphragm filter plate and avoid residual attachments, enabling the diaphragm filter plate to be fully automatically self-cleaned, improving the cleaning speed, and thus effectively improving the filtration efficiency of the diaphragm filter plate.

[0018] 2. By reversing the motor, the moving seat can move upward. When the cross-sectional plate is separated from the diaphragm filter plate, the cleaning plate fixedly connected to the cross-sectional plate will reset under the torsional force of the torsion spring, so that the cross-sectional plate and the cleaning plate will not flip randomly and affect the next round of cleaning.

[0019] 3. By twisting the bolt to rotate threadedly, the bolt is withdrawn from the inside of the clamping block and disconnected, and thus the top seat can be disassembled from between the two side fixing plates, facilitating the maintenance of the components inside the top seat and extending the service life.

Both the gripper 107 and the movers 106 are prior arts and are used to move and separate the diaphragm filter plates 104;

[0033] A cleaning unit 200, including side fixing plates 201 fixedly connected with the two groups of movers 106, a top seat 202 is detachably connected between the two groups of side fixing plates 201, and a storage groove 211 and a power groove 212 are formed inside the top seat 202, a power assembly 213 is arranged inside the power groove 212, two groups of moving seats 209 are movably connected inside the storage groove 211, and sliding grooves 208 are formed on opposite sides of the moving seats 209. The two groups of moving seats 209 are horizontally symmetrically designed. Two groups of bidirectional threaded rods 203 are rotatably connected inside the top seat 202, and both ends of each bidirectional threaded rod 203 are threadedly connected with threaded cylinders 204. A lower side of each group of threaded cylinders 204 is rotatably connected with a connecting rod 205, and a lower side surface of each connecting rod 205 is rotatably connected with a connecting block 206. The middle parts of every two groups of connecting rods 205 are rotatably connected through a rotating shaft. One side of each group of connecting blocks 206 is fixedly connected with a sliding plate 207, and surfaces of the sliding plates 207 are slidably connected with inner wall surfaces of the sliding grooves 208. Scraper assemblies 210 are arranged on opposite sides of the two groups of moving seats 209 close to each other, so that the moving seats 209 can move up and down inside the top seat 202.

[0034] Among them, two groups of limiting rods 214 are fixedly connected to the inner wall surfaces on both sides of the storage groove 211. Moving grooves that match the limiting rods 214 are formed on both sides of the two moving seats 209. The limiting rods 214 are all slidably connected to the inner wall surfaces of the moving grooves. Two groups of limiting grooves 108 are formed on both side surfaces of each diaphragm filter plate 104, and the inner wall surfaces of the limiting grooves 108 are all slidably connected to the moving seats 209, which has a limiting effect and enables the moving seats 209 to stably move up and down on the surface of the diaphragm filter plates 104.

[0035] Furthermore, the two scraper assemblies 210 both include cleaning plates 210a that are closely attached to the inner wall surfaces of the moving seats 209. Transverse plates 210b are fixedly connected to the closer sides of the cleaning plates 210a. Two groups of rotating shafts 210c are fixedly connected to both sides of the two cleaning plates 210a, and the rotating shafts 210c are all rotatably connected to the moving seats 209. Torsion springs 210d are sleeved on the surfaces of each group of the rotating shafts 210c, and the two ends of the torsion springs 210d are respectively fixedly connected to the moving seats 209 and the cleaning plates 210a.

[0036] Furthermore, the length dimensions of the two transverse plates 210b are the same as the inner diameter dimensions of the moving seats 209, and the length dimensions of the two cleaning plates 210a are both smaller than the dimensions of the transverse plates 210b, enabling the lower side surfaces of the cleaning plates 210a to smoothly fit the surfaces of the diaphragm filter plates 104 and enabling the transverse plates 210b to cooperate with the filter cake generation areas of the diaphragm filter plates 104.

[0037] Furthermore, the power assembly 213 includes a motor 213a fixedly connected to the top seat 202, and a worm 213b is fixedly connected to the output end shaft of the motor 213a. Two groups of worm wheels 213c are meshed with the lower side surface of the worm 213b, and the two groups of worm wheels 213c are fixedly connected to the two bidirectional threaded rods 203. By driving the worm 213b to rotate through the motor 213a, the worm 213b drives the bidirectional threaded rods 203 to rotate through the two groups of worm wheels 213c.

[0038] Even further, clamping blocks 215 are snap-fitted to the upper ends of the two side fixing plates 201, and bolts 216 are threadedly connected to one sides of the clamping blocks 215. The two bolts 216 are all connected to the side fixing plates 201 through threads. The closer sides of the two clamping blocks 215 are fixedly connected to the top seat 202. By rotating the bolts 216 through threads, the clamping blocks 215 can be disassembled from the upper sides of the side fixing plates 201, and thus it is convenient to disassemble the top seat 202 for maintenance.

[0039] During use, after filtration is completed, move the mover 106 to both sides of the specified diaphragm filter plate 104, then clamp the fixed block 105 through the gripper 107 to drive the diaphragm filter plate 104 to move. At the same time, start the motor 213a to drive the worm 213b to rotate forward. The worm wheel 213c engaged with the worm 213b drives the bidirectional threaded rod 203 to rotate. The threaded cylinder 204 threadedly connected to the bidirectional threaded rod 203 pushes the connecting rod 205 to move, so that the connecting rod 205 pushes the connecting block 206 to move downward. Furthermore, the slide plate 207 fixedly connected to the connecting block 206 slides inside the chute 208, driving the moving seat 209 to move downward. At the same time, the limiting rod 214 slides inside the moving groove. Then, the moving seat 209 is slidably connected to the limiting groove 108 to limit the moving direction of the moving seat 209. Then, the lower surface of the cross-sectional plate 210b abuts against the upper surface of the diaphragm filter plate 104, so that the cleaning plate 210a fixedly connected to the cross-sectional plate 210b flips around the rotating shaft 210c, and the lower end of the cleaning plate 210a contacts the filter cake. Through the push of the moving seat 209, the cleaning plate 210a can scrape the filter cake from the surface of the diaphragm filter plate 104 and avoid residual attachments, enabling the diaphragm filter plate 104 to be fully automatically self-cleaned.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
