Description

Technical Field

[0001] This invention relates to the field of filter technology, specifically to a slip chain blanket type vacuum belt filter. Background Technology

[0002] Vacuum belt filters are highly efficient, continuous, and automated solid-liquid separation devices widely used in chemical, metallurgical, and environmental protection industries. This equipment uses filter cloth with selectable pore sizes as the filter medium. After the material is evenly distributed on the surface of the filter cloth, solid-liquid separation is achieved under the suction force generated by the vacuum system, and multi-stage washing of the filter cake is also possible. As the filter cloth continuously moves at an adjustable speed, the filter cake layer gradually forms and is continuously dehydrated, with the moisture content continuously decreasing, finally completing automatic unloading in the discharge zone. The entire process is continuous, with a large processing capacity and low filter cake moisture content. Furthermore, it can adapt to different material characteristics by adjusting parameters such as belt speed and vacuum degree, improving production efficiency while reducing manual labor intensity, demonstrating excellent process adaptability and operational economy.

[0003] The authorized publication number is CN214182086U, which discloses a vacuum belt filter with tensionable filter cloth. This equipment uses an external power supply to drive a transmission belt above the vacuum chamber, and a drive component moves the filter belt. During material transport, solid-liquid separation is achieved through vacuum suction. However, in practical use, it has been found that the transmission belt relies solely on drive rollers at both ends for support and transmission. When the vacuum chamber is operating, due to negative pressure and material load, the transmission belt is prone to significant deformation, affecting filtration stability, accelerating filter belt wear, and shortening its service life. Furthermore, maintenance of the vacuum chamber requires complete shutdown and manual climbing to the top of the frame, resulting in low maintenance efficiency, safety hazards, and increased labor intensity and time costs.

[0004] Based on this, a slip-chain blanket vacuum belt filter is now available, which can eliminate the drawbacks of existing devices. Summary of the Invention

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-10 As shown, the slip chain blanket type vacuum belt filter includes a conveyor belt 11 and a vacuum box 21. Both ends of the conveyor belt 11 are fitted with drive rollers. Several water guide grooves 12 are arrayed on the conveyor belt 11, each with a drainage hole in the center. A filter belt 15 is fitted onto the upper end of the conveyor belt 11, and several guide rollers 17 are fitted onto the bottom end of the filter belt 15. The guide rollers 17 are all installed inside the mounting frame 14. A pressure roller 18 is tightly attached to the upper end of the filter belt 15. A fabric plate 36 is fitted onto one side of the pressure roller 18, and a sliding box 37 is located at the end of the fabric plate 36. The device has an internal feed pipe 38. The upper end of the mounting frame 14 is equipped with an adjustment mechanism for adjusting the material feeding amount. The vacuum box 21 is installed inside the conveyor belt 11. A fixing frame 22 is installed on the upper end of the vacuum box 21. A wear-resistant strip 23 is installed on the upper end of the fixing frame 22. The upper end of the wear-resistant strip 23 is in close contact with the upper end of the inside of the conveyor belt 11. The inner side of the mounting frame 14 is equipped with a fixing mechanism for fixing the vacuum box 21. The adjustment mechanism facilitates the adjustment of the material feeding amount on the upper end of the filter belt 15. The fixing mechanism facilitates the quick disassembly and assembly of the vacuum box 21, thereby facilitating the replacement of the wear-resistant strip 23. The drive rollers are all rotatably mounted inside the mounting frame 14. One end of each drive roller is fixedly connected to the output end of the first reducer. The input end of the first reducer is fixedly connected to the output end of the first motor 13. The first reducer and the first motor 13 are both mounted on one side of the mounting frame 14. Several guide rollers 17 are rotatably mounted inside the mounting frame 14. The pressure roller 18 is rotatably mounted on the upper end of the mounting frame 14. Several support rollers 19 are tightly attached to the bottom end of the conveyor belt 11. The support rollers 19 are all rotatably mounted inside the mounting frame 14. In use, when solid-liquid separation of materials is required, the filter belt 15 alternately passes through several guide rollers 17. Under the action of the pressure roller 18, the filter belt 15 is tightly attached to the upper end of the conveyor belt 11. Then, the first motor 13 drives the conveyor belt 11 to rotate through the first reducer. The material distribution plate 36 arranges the material on the upper end of the filter belt 15. Then, the vacuum box 21 separates the filtrate from the material.

[0030] Both ends of the conveyor belt 11 are equipped with skirt belts 16, and the ends of the skirt belts 16 are inclined. A number of connecting pipes 31 are connected to one side of the vacuum box 21. The ends of the connecting pipes 31 are connected to the input end of the filtrate pipe 32. The filtrate pipe 32 is installed on one side of the mounting frame 14. The input end of the filtrate pipe 32 is connected to the external vacuum component and the external gas-liquid separation component. In use, when the material moves with the filter belt 15, the external vacuum component and the external gas-liquid separation component create a vacuum inside the vacuum box 21 through the filtrate pipe 32 and the connecting pipes 31. The vacuum box 21 separates the filtrate in the material through the drain hole and the water guide trough 12.

[0031] The adjustment mechanism includes an adjustment plate 45. The upper end of the fabric plate 36 is provided with several partitions. The end of the fabric plate 36 is provided with the adjustment plate 45 in cooperation with the partitions. Both ends of the adjustment plate 45 are fixedly provided with sliding frames. The sliding frames are slidably disposed on the connecting frame 46. The sliding frames are fixedly connected to the connecting frame 46 by screws. The connecting frame 46 is fixedly disposed at the end of the fabric plate 36. The end of the connecting frame 46 is provided with a second guide slide rod. The second guide slide rod is fixedly disposed inside the second mounting frame. The second mounting frame is fixedly disposed at the upper end of the mounting frame 14. The feed pipe 38 is installed in the mounting hole at the upper end of the first mounting frame 39. The first mounting frame 39 is fixedly disposed at the upper end of the mounting frame 14.

[0032] The feed pipe 38 is symmetrically fitted with baffle plates 42 at its ends. Each baffle plate 42 has a connecting rod 41 hinged to its end. The other end of each connecting rod 41 is hinged to the upper part of the sliding box 37. The baffle plates 42 are slidably mounted on guide slides. Each guide slide is fixed to one end of the feed pipe 38. Fixed rods are fixed on both sides of the sliding box 37. A first guide slide rod 40 is slidably mounted at the end of each fixed rod. The first guide slide rod 40 is fixed to the upper part of the first mounting bracket 39. A second return spring 43 is fixed to the end of each fixed rod. An adjusting slip ring is fitted to the other end of each second return spring 43. The adjusting slip ring is slidably mounted on the first guide slide rod 40. A fixed tube is fixed to the bottom end of the adjusting slip ring. A stop block 44 is slidably mounted inside the fixed tube. The stop block 44 is rotatably mounted on... One end of the screw is installed in the threaded hole at the end of the fixed tube. When it is necessary to adjust the material discharge amount at the end of the cloth plate 36, the distance between the bottom end of the adjusting plate 45 and the top end of the cloth plate 36 is adjusted, and then the adjusting plate 45 is fixed. During operation, the external feeding component conveys material into the feed pipe 38, and the material is discharged through the end of the cloth plate 36. As the material discharge amount at the end of the cloth plate 36 decreases, some material will be temporarily stored at the top of the cloth plate 36, which increases the overall weight of the cloth plate 36. The cloth plate 36 drives the sliding box 37 to slide, which compresses the second return spring 43. At the same time, the sliding box 37 drives the baffle plate 42 to slide through the connecting rod 41. The baffle plate 42 adjusts the size of the discharge port at the end of the feed pipe 38, thereby reducing the material discharge amount at the end of the feed pipe 38 and balancing the material discharge.

[0033] The fixing mechanism includes a hinge seat 25 and a plug rod 27. A plurality of hinge seats 25 are arrayed at the bottom end of the vacuum chamber 21. Each hinge seat 25 is hinged to the upper end of a fixing frame 26. The fixing frames 26 are all installed inside the mounting frame 14. A limiting frame is fixedly provided at the bottom end of each hinge seat 25. A plug rod 27 is slidably disposed within each limiting frame. The plug rod 27 is fixedly disposed at one end of a sliding tube, which is slidably disposed on the fixing frame 26. A limiting frame 28 is fixedly provided at the other end of the sliding tube. Limiting holes are symmetrically provided on the limiting frame 28, and a fitting is inserted into one of the limiting holes. A limiting post 29 is provided, which is slidably disposed inside the mounting tube. The mounting tube is fixedly disposed on the fixing frame 26. A first return spring 30 is provided between one end of the limiting post 29 and one end inside the mounting tube. In use, when it is necessary to replace the wear-resistant strip 23, the limiting post 29 is pushed, so that the limiting frame 28 drives the plug rod 27 to slide. The plug rod 27 disengages from the limiting frame, and then the limiting post 29 is inserted into another limiting hole on the limiting frame 28. Then, the vacuum box 21 rotates along the hinge joint between the hinge seat 25 and the fixing frame 26, which facilitates the replacement of the wear-resistant strip 23.

[0034] The upper part of the conveyor belt 11 is symmetrically fitted with a sliding chain mat 33. Both sides of the sliding chain mat 33 are fitted with chain belts 34, and both ends of the chain belts 34 are fitted with sprockets. The sprockets are coaxially mounted on a drive shaft. The drive shaft is rotatably disposed in the rotation hole at the end of the retaining plate. The retaining plates are fixedly disposed inside the mounting frame 14. One end of the drive shaft is fixedly connected to the output end of the second reducer. The input end of the second reducer is fixedly connected to the output end of the second motor 35. The second motor 35 and the second reducer are both mounted on one side of the mounting frame 14. In use, when the vacuum box 21 is working, the second motor 35 is started, which drives the chain belts 34 to rotate. The chain belts 34 drive the sliding chain mats 33 to rotate. The sliding chain mats 33 can support the conveyor belt 11, thereby reducing the deformation of the conveyor belt 11.

[0035] The bottom end of the wear-resistant strip 23 is provided with a plurality of limiting blocks 24. The bottom end of the fixed frame 22 is provided with limiting grooves corresponding to the positions of the limiting blocks 24, so as to prevent the wear-resistant strip 23 from slipping during use.

[0036] A scraper 20 is installed at the end of the mounting frame 14. The end of the scraper 20 is in close contact with the outside of the filter belt 15. A cleaning pipe 47 is provided at the bottom of the inside of the mounting frame 14. The cleaning pipe 47 is connected to the input end of the external liquid supply component. The cleaning pipe 47 is located above the bottom end of the filter belt 15. In use, when the filter cake moves to the end of the mounting frame 14 with the filter belt 15, the scraper 20 can scrape off the filter cake attached to the filter belt 15. Then the cleaning pipe 47 can backwash the filter belt 15, thereby cleaning the filter belt 15.

[0037] The above embodiments disclose a slip chain blanket type vacuum belt filter. When solid-liquid separation of materials is required, the filter belt 15 alternately passes through several guide rollers 17. Under the action of the pressure roller 18, the filter belt 15 is brought into close contact with the upper end of the conveyor belt 11. Subsequently, the first motor 13 drives the conveyor belt 11 to rotate through the first reducer. The material is added to the upper end of the material distribution plate 36 through the feed pipe 38. The material distribution plate 36 evenly distributes the material on the upper end of the filter belt 15. Then, the external vacuum component and the external gas-liquid separation component, through the filtrate pipe 32 and the connecting pipe 31, create a vacuum chamber. A vacuum is generated inside the vacuum chamber 21. The vacuum chamber 21 separates the filtrate in the material through the drain hole and the water guide trough 12. At the same time, the second motor 35 is started, which drives the chain belt 34 to rotate. The chain belt 34 drives the sliding chain blanket 33 to rotate. The sliding chain blanket 33 can support the conveyor belt 11, thereby reducing the deformation of the conveyor belt 11. After the filter cake moves with the filter belt 15 to the end of the mounting frame 14, the scraper blade 20 can scrape off the filter cake attached to the filter belt 15. Then the cleaning pipe 47 can reverse the rinsing of the filter belt 15, thereby cleaning the filter belt 15. When the material discharge amount at the end of the fabric plate 36 needs to be adjusted, the distance between the bottom end of the adjusting plate 45 and the top end of the fabric plate 36 is adjusted, and then the adjusting plate 45 is fixed. During operation, the external feeding component conveys material into the feed pipe 38, and the material is discharged through the end of the fabric plate 36. As the material discharge amount at the end of the fabric plate 36 decreases, some material will be temporarily stored at the top of the fabric plate 36, which increases the overall weight of the fabric plate 36. The fabric plate 36 drives the sliding box 37 to slide, which compresses the second return spring 43. At the same time, the sliding box 37 drives the baffle plate 42 to slide through the connecting rod 41. The baffle plate 42 adjusts the size of the discharge port at the end of the feed pipe 38, thereby reducing the material discharge amount at the end of the feed pipe 38 and balancing the material discharge. When the wear strip 23 needs to be replaced, push the limiting post 29 so that the limiting frame 28 drives the plug rod 27 to slide. The plug rod 27 disengages from the limiting frame, and then the limiting post 29 is inserted into another limiting hole on the limiting frame 28. Then the vacuum box 21 rotates along the hinge joint between the hinge seat 25 and the fixed frame 26, which facilitates the replacement of the wear strip 23.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
