Description

Technical Field

[0001] This utility model relates to the field of dehydration technology, and in particular to a composite dehydration device. Background Technology

[0002] Vacuum belt dewatering machines utilize a vacuum pump to generate negative pressure. Filter cloth is placed flat on a negative pressure system composed of rubber belts. Raw materials flow onto the filter cloth surface after passing through a distributor, and solid-liquid separation is achieved through vacuum suction. Traditional vacuum belt dewatering systems mainly consist of a vacuum pump, vacuum tank, vacuum belt dewatering machine, and filter cloth. These systems are often used in chemical and mining industries, primarily targeting raw materials with a high proportion of coarse solid particles in the mixed liquid that are easily dewatered. However, this traditional dewatering method fails to operate when the raw material has a low solid-liquid ratio, low coarse particle content in the solid component, or a large number of fine floating particles formed after chemical reactions in the ore. Because the mixed liquid contains many fine floating particles, upon contact with the filter cloth, it quickly blocks the filter cloth's pores, preventing subsequent intake of the raw material mixture from being dewatered, thus rendering the system ineffective. Blindly increasing the mesh size of the filter cloth will cause fine particles to penetrate the filter cloth and enter the filtrate collection tank, making further filtration of the fine particles in the filtrate much more difficult. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a composite dehydration device.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A composite dewatering device includes a frame, a feed pipe, a large particle distributor, a small particle distributor, a hydrocyclone, a small particle conveying pipe, a filter cloth, a belt conveyor assembly, and a pumping assembly. The belt conveyor assembly is mounted on the frame, and the filter cloth that cooperates with the belt conveyor assembly is also mounted on the frame. The feed pipe is mounted on the frame, and its input end is connected to the middle of the hydrocyclone. The lower end of the hydrocyclone is connected to the large particle distributor. One end of the small particle conveying pipe is connected to the upper end of the hydrocyclone, and the other end of the small particle conveying pipe is connected to the upper end of the small particle distributor. A first control valve is mounted on the small particle conveying pipe.

[0006] Furthermore, a regulating pipe is sealed to the feed pipe, and a regulating valve is provided on the regulating pipe.

[0007] Furthermore, a flow meter is sealed on the feed pipe, and the flow meter is located between the regulating pipe and the hydrocyclone.

[0008] Furthermore, a return pipe is sealed on the small particle conveying pipe, the input end of the small particle conveying pipe is located between the hydrocyclone and the first control valve, and a second control valve is provided on the return pipe.

[0009] Furthermore, the belt conveyor assembly includes a transmission belt, a main pulley, a secondary pulley, and a drive motor.

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See Figures 1-4 This utility model provides a technical solution:

[0025] A composite dewatering device includes a frame 1, a feed pipe 2, a large particle distributor 3, a small particle distributor 4, a hydrocyclone 5, a small particle conveying pipe 6, a filter cloth 7, a belt conveyor assembly, and a pumping assembly. The frame 1 is equipped with a belt conveyor assembly and a filter cloth 7 that cooperates with the belt conveyor assembly. The feed pipe 2 is located on the frame 1, and its input end is connected to the middle of the hydrocyclone 5. The lower end of the hydrocyclone 5 is connected to the large particle distributor 3. One end of the small particle conveying pipe 6 is connected to the upper end of the hydrocyclone 5, and the other end of the small particle conveying pipe 6 is connected to the upper end of the small particle distributor 4. A first control valve 8 is installed on the small particle conveying pipe 6. Filter cloth 7 is mounted on filter cloth 7 rotatably on both ends of the frame 1. The frame 1 is used to install the feed pipe 2, large particle distributor 3, small particle distributor 4, hydrocyclone 5, small particle conveying pipe 6, filter cloth 7, belt conveyor assembly, and water pumping assembly. The belt conveyor assembly moves the filter cloth 7, and the water pumping assembly quickly removes water from the filter cloth 7. Unfiltered raw materials first enter the hydrocyclone 5 through the feed pipe 2. The hydrocyclone 5 classifies the raw materials into particles of different sizes. Large particles enter the filter cloth 7 through the large particle distributor 3, while small particles enter the filter cloth 7 through the small particle conveying pipe 6 and accumulate on top of the large particles. The first control valve 8 controls the working time of the small particle conveying pipe 6, causing the small particles exiting the small particle conveying pipe 6 to fall onto the top of the large particles. The frame 1 is equipped with multiple cloth rollers 26. The filter cloth 7 is annular. Raw materials fall onto the filter cloth 7, causing it to adhere tightly to the upper surface of the conveyor belt 14. The conveyor belt 14 drives the filter cloth 7 during operation.

[0026] In some embodiments, a regulating pipe 9 is sealed to the feed pipe 2, and a regulating valve 10 is provided on the regulating pipe 9. A flow meter 11 is sealed to the feed pipe 2, and the flow meter 11 is located between the regulating pipe 9 and the hydrocyclone 5. Both the flow meter 11 and the regulating valve 10 are existing technologies. The flow meter 11 ensures stable discharge from both the large particle distributor 3 and the small particle distributor 4. If too much material is fed into the feed pipe 2, the regulating valve 10 can be opened, allowing some raw material to return to the raw material pool through the regulating pipe 9, preventing the hydrocyclone 5 from being unable to keep up with the processing speed.

[0027] In some embodiments, a return pipe 12 is sealed on the small particle conveying pipe 6. The input end of the small particle conveying pipe 6 is located between the hydrocyclone 5 and the first control valve 8, and a second control valve 13 is provided on the return pipe 12. The second control valve 13 is a prior art valve. When the amount of small particles in the raw material is very large, while the amount of large particles is relatively small, and some small particles cannot be completely stacked on top of the large particles, some small particles return to the raw material pool through the return pipe 12.

[0028] In some embodiments, the belt conveyor assembly includes a transmission belt 14, a main pulley 15, a secondary pulley 16, and a drive motor 17. The main pulley 15 is rotatably mounted on one end of the frame 1, and the secondary pulley 16 is rotatably mounted on one end of the frame 1 and the other end. The two ends of the transmission belt 14 are respectively mounted on the main pulley 15 and the secondary pulley 16. The drive motor 17 is fixedly mounted on the frame 1 and is used to drive the main pulley 15 to rotate. The transmission belt 14 is located inside the filter cloth 7, and the transmission belt 14 is provided with water filtering holes 18 that cooperate with the water pumping assembly. The drive motor 17 is a prior art technology and drives the main pulley 15 to rotate. The main pulley 15 drives the transmission belt 14 and the secondary pulley 16 to work together. Both the main pulley 15 and the secondary pulley 16 are synchronous pulleys. The outer surface of the transmission belt 14 is provided with protrusions to prevent relative slippage between the filter cloth 7 and the transmission belt 14.

[0029] In some embodiments, the pumping assembly includes a vacuum tank 19, a vacuum pump 20, and a dehydration plate 21. The dehydration plate 21 is fixedly mounted on the frame 1 and located inside the conveyor belt 14. A filtrate collection tank 22, which cooperates with the conveyor belt 14, is provided on the dehydration plate 21. One end of the filtrate collection tank 22 is connected to the vacuum tank 19, and the vacuum tank 19 is connected to the vacuum pump 20. Both the vacuum tank 19 and the vacuum pump 20 are existing technologies. The vacuum tank 19 and the vacuum pump 20 work together to extract liquid from the filtrate collection tank 22 on the dehydration plate 21. The conveyor belt 14 slides on the dehydration plate 21.

[0030] In some embodiments, at least two vacuum tanks 19 are connected to the vacuum pump 20 via a large vacuum tube 23. Each vacuum tank 19 is equipped with a manifold plate 24 and is connected to multiple filtrate collection tanks 22 via multiple small vacuum tubes 25. The presence of numerous vacuum tanks 19 and small vacuum tubes 25 accelerates the filtration of raw materials on the filter cloth 7.

[0031] In some embodiments, a support wheel 27 is rotatably mounted on the end of the frame 1, and a scraper 28 that cooperates with the support wheel 27 is mounted on the frame 1. The filter cloth 7 is disposed between the support wheel 27 and the scraper 28. The support wheel 27 is provided to facilitate its cooperation with the scraper 28, allowing the filter cloth 7 to move smoothly and scraping off the material on the filter cloth 7.
