Description

Technical Field

[0001] The utility model relates to the technical field of potato starch preparation, and more particularly to a self-locking quick-detachable filter screen structure of a potato starch wastewater filter. Background Art

[0002] In the potato starch production industry, wastewater filtration equipment plays a vital role. The wastewater generated during the production process contains a large amount of starch particles and other impurities, which need to be effectively filtered and treated. The filter is the core component of the filtration equipment. However, there are many technical problems that need to be solved in the wastewater filtration equipment on the market.

[0003] In terms of filter maintenance, there are significant problems with the installation and disassembly operations of filters in the existing technology. Bolts and other fixings are generally used for installation and fixation, which require multiple turns to tighten or loosen. This is especially time-consuming when frequently replacing filters. In addition, when the equipment space is small or the operating position is limited, it is difficult to tighten the bolts, and special tools are usually required. Manual operation is difficult to ensure the tightening effect, and repeated disassembly and assembly will cause thread wear, affecting the fixing effect and posing a safety hazard. At the same time, the bolts must be installed to ensure accurate thread alignment to prevent installation deviation problems.

[0004] In addition, in terms of filtration efficiency, the existing technology generally adopts a static filter structure for filtration treatment. This simple filtration method has obvious shortcomings. Especially in large-scale production processes, inefficient filtration systems not only affect production progress, but may also lead to incomplete wastewater treatment, causing environmental pollution and waste of resources.

[0005] In addition, although some improved quick-disassembly and assembly filter devices have appeared on the market, attempting to improve maintenance efficiency by simplifying the disassembly and assembly process, these devices have exposed serious structural stability problems in actual applications. Due to the excessive pursuit of disassembly and assembly convenience and neglect of structural strength, these simplified fixed structures are very easy to loosen during the long-term operation of the equipment. Especially under conditions where the equipment vibrates more, the filter fixing structure may gradually loosen, which not only reduces the filtration efficiency, but may also cause equipment damage and increase maintenance costs. Once the filter fixing fails, it is more likely to cause wastewater treatment to fail to meet standards, affecting the normal operation of the entire production system. Utility Model Content

[0015] Compared with the prior art, the present invention provides a self-locking quick-release filter screen structure for a potato starch wastewater filter, which has the following beneficial effects:

[0016] 1. The fixing device adopts an innovative linkage structure of a fixed sleeve, a sliding sleeve and a rotating sleeve. Through the simple operation of the rotating plate and the rotating sleeve, combined with the action of the reset spring, the fixing sleeve and the fixing rod can be quickly unlocked and removed. Unlocking and fixing can be completed without any special tools, which greatly shortens the maintenance time and completely solves the problem of multiple turns and tool assistance required for traditional bolt disassembly and assembly. Especially in an environment with limited equipment space, the filter can be disassembled and assembled with simple rotation and pulling actions, avoiding the problem of precise thread alignment during traditional bolt installation, and the operation is more convenient.

[0017] 2. The filtering device installed in the treatment cylinder achieves efficient filtration of wastewater through the ingenious cooperation of the feed bin, motor, fixed frame, connecting frame, guide block, rotating frame and filter screen. The motor drives the rotating frame to rotate, which accelerates the flow speed of wastewater in the connecting frame and improves the contact efficiency with the filter screen, allowing the wastewater to quickly pass through the filter screen and enter the space between the treatment cylinder and the filter screen, while impurities and starch particles are effectively retained on the inside of the filter screen and the connecting frame.

[0018] 3. The design of the locking mechanism is particularly ingenious. Through the coordinated work of components such as the rotating plate, sliding sleeve and plug rod, a complete anti-loosening system is constructed. The precise coordination of the groove with the horizontal plate and the vertical plate, the design of inserting the plug rod into the slot, and the limiting effect of the sliding sleeve on the plug rod ensure the stability of the entire structure during equipment operation. In particular, the linkage design of the vertical plate and the horizontal plate, combined with the role of the sliding sleeve, forms a multiple insurance mechanism, which fundamentally solves the problem of traditional installation devices being easily loosened during operation and ensures the stable and normal operation of the equipment.

[0031] The sliding sleeve 13 is connected to a push spring 21 on one side, and the other end of the push spring 21 is in contact with the rotating plate 11.

[0032] In this embodiment, when it is necessary to clean and maintain the inside of the filter screen 28, the two hydraulic cylinders 36 installed on the base 35 are first opened synchronously, and then the hydraulic cylinder 36 pushes the lifting frame 38 to rise through the hydraulic rod 37 connected to the output end. At the same time, the lifting frame 38 will drive the fixed frame 24 to rise along the slide rod 39. When the bottom end of the guide block 26 rises to the top of the treatment cylinder 1, the hydraulic cylinder 36 is closed, and then the first clamping frame 30 and the second clamping frame 31 on the outside of the connecting frame 25 and the fixed frame 24 are removed. First, the rotating plate 11 is rotated, and the rotating plate 11 will drive the yield groove 12 to rotate. When the yield groove 12 rotates to the position corresponding to the transverse plate 15, the sliding sleeve 13 is pushed, and the sliding sleeve 13 will drive the longitudinal plate 14 and the transverse plate 15 to slide, so that the longitudinal plate 14 and the transverse plate 15 passes through the give way slot 12, and at the same time, the sliding sleeve 13 cooperates with the rotating plate 11 to squeeze the push spring 21. When the push spring 21 is squeezed to the limit, the corresponding transverse plate 15 passes through the give way slot 12 and reaches the other side of the rotating plate 11, and then the rotating plate 11 continues to rotate, so that the rotating plate 11 drives the give way slot 12 to move to a position that does not correspond to the transverse plate 15. At this time, the longitudinal plate 14 and the corresponding transverse plate 15 cooperate to limit the sliding sleeve 13 to one side of the rotating plate 11. At this time, the inner wall of the sliding sleeve 13 no longer limits the outer end of the insertion rod 16, and then the rotating sleeve 9 is rotated. The rotating sleeve 9 will drive the multiple insertion rods 16 set on the side wall to move, and then the side wall of the slot 17 squeezes one end of the insertion rod 16. Due to the rounded corners at the edge of the slot 17 and the end of the insertion rod 16, one end of the insertion rod 16 slides out of the slot 17. , and the other end of the insertion rod 16 will drive the return spring 18 to stretch, and at the same time the rotating sleeve 9 will drive the spiral block 6 to rotate through the connecting plate 5, and then the spiral block 6 will slide along the spiral groove 4. Due to the spiral structure of the spiral groove 4 and the clamping frame 20 imposes a limit on the sliding sleeve 3, and then the sliding sleeve 3 will drive the spiral groove 4 and the sliding groove 8 to slide. Due to the special structural design of the sliding groove 8, the sliding rod 10 will then drive the clamping frame 20 to slide out of the clamping groove 19, and then pull the fixed sleeve 2 and the fixed rod 7 to both sides respectively, so that the fixed sleeve 2 and the fixed rod 7 can be removed, and then the first clamping frame 30 and the second clamping frame 31 are pulled to both sides, so that the first clamping frame 30 and the second clamping frame 31 are opened along the rotating shaft 32, and then the first clamping frame 30 and the second clamping frame 31 is removed, and then the connecting frame 25, the filter screen 28 and the guide block 26 are removed from under the fixing frame 24, and then the impurities and starch particles on the inside of the connecting frame 25 can be cleaned out, and then the first bracket 30 and the second bracket 31 set on the outside of the connecting frame 25 and the guide block 26 can be removed according to the above process, and then the filter screen 28 can be replaced and thoroughly cleaned. After replacement and thorough cleaning, the guide block 26, the connecting frame 25 and the fixing frame 24 are reassembled together, and the filter screen 28 is surrounded and arranged on the outside of the connecting frame 25, and then it is limited again by the first bracket 30 and the second bracket 31, and the card slot 33 is engaged with the clamping ring 34 inside, and then the fixing rod 7 is passed through the reserved holes on the first bracket 30 and the second bracket 31.Then the fixing sleeve 2 is fitted to the outside of the fixing rod 7 from the other side, and then the rotating sleeve 9 is rotated in the opposite direction, so that the rotating sleeve 9 drives the insertion rod 16 and the connecting plate 5 to rotate, and then the connecting plate 5 will drive the spiral block 6 to rotate, and the cooperation of the threaded block and the spiral groove 4 will make the sliding sleeve 3 slide and reset, and then the sliding sleeve 3 will drive the sliding groove 8 to reset, and then the sliding rod 10 will drive the locking frame 20 to re-engage in the locking groove 19, at this time the return spring 18 just drives the insertion rod 16 to reset, so that one end of the insertion rod 16 is reinserted into the original slot 17, and the rotating plate 11 is rotated again at this time, so that the rotating plate 11 drives the giving slot 12 to move, and when the giving slot 12 moves to the corresponding position with the horizontal plate 15, the push spring 21 pushes the sliding The sleeve 13 slides back to its original position, and then the sleeve 13 drives the longitudinal plate 14 and the transverse plate 15 to return to their original position. When the push spring 21 is fully reset, the other two transverse plates 15 move to the two sides of the rotating plate 11 respectively. The rotating plate 11 continues to rotate, so that the rotating plate 11 drives the yielding groove 12 to a position that does not correspond to the transverse plate 15. At this time, the longitudinal plate 14 and the corresponding two transverse plates 15 cooperate to limit the sleeve 13 to one side of the rotating plate 11, so that the sleeve 13 will not slide easily. Then the inner wall of the sleeve 13 will limit the outer end of the insertion rod 16 again, thereby preventing the insertion rod 16 from moving. Then the insertion rod 16 and the slot 17 cooperate to limit the rotating sleeve 9, preventing the rotating sleeve 9 from rotating, thereby preventing accidental unlocking, thereby ensuring the stability of the fixed structure.

[0038] More specifically, when the equipment needs to be used, the wastewater is first transported to the inside of the connecting frame 25 through the feed bin 22, and then the motor 23 is turned on. The motor 23 drives the rotating frame 27 connected to the output end to rotate, so that the rotating frame 27 drives the wastewater in the connecting frame 25 to flow, accelerating the flow rate, and then when the wastewater comes into contact with the filter screen 28 surrounded by the outside of the connecting frame 25, the wastewater will pass through the filter screen 28 into the space between the treatment cylinder 1 and the filter screen 28, while impurities and starch particles will be retained on the inside of the filter screen 28 and the connecting frame 25, and then the wastewater flowing out to the outside of the filter screen 28 will be transported to the next process through the conveying equipment connected to the discharge port 29.

[0039] In summary, when the overall equipment is in use or running: when the equipment needs to be used, the wastewater is first transported to the inside of the connecting frame 25 through the feed bin 22, and then the motor 23 is turned on. The motor 23 drives the rotating frame 27 connected to the output end to rotate, so that the rotating frame 27 drives the wastewater in the connecting frame 25 to flow, accelerating the flow rate, and then when the wastewater comes into contact with the filter screen 28 surrounded by the outside of the connecting frame 25, the wastewater will pass through the filter screen 28 into the space between the treatment cylinder 1 and the filter screen 28, while impurities and starch particles will be retained on the inside of the filter screen 28 and the connecting frame 25, and then the wastewater flowing out to the outside of the filter screen 28 will be transported to the next process through the conveying equipment external to the discharge port 29.

[0040] When it is necessary to clean and maintain the inside of the filter screen 28, first, the two hydraulic cylinders 36 installed on the base 35 are opened synchronously, and then the hydraulic cylinder 36 pushes the lifting frame 38 to rise through the hydraulic rod 37 connected to the output end. At the same time, the lifting frame 38 will drive the fixed frame 24 to rise along the sliding rod 39. When the bottom end of the guide block 26 rises to the top of the treatment cylinder 1, the hydraulic cylinder 36 is closed, and then the first clamping frame 30 and the second clamping frame 31 on the outside of the connecting frame 25 and the fixed frame 24 are removed. First, the rotating plate 11 is rotated, and the rotating plate 11 will drive the yield groove 12 to rotate. When the yield groove 12 rotates to the position corresponding to the transverse plate 15, the sliding sleeve 13 is pushed, and the sliding sleeve 13 will drive the longitudinal plate 14 and the transverse plate 15 to slide, so that the longitudinal plate 14 and the transverse plate 15 pass through the yield groove 12. When the sliding sleeve 13 cooperates with the rotating plate 11 to squeeze the push spring 21, and when the push spring 21 is squeezed to the limit, the corresponding transverse plate 15 passes through the giving groove 12 and reaches the other side of the rotating plate 11, and then the rotating plate 11 continues to rotate, so that the rotating plate 11 drives the giving groove 12 to move to a position that does not correspond to the transverse plate 15. At this time, the longitudinal plate 14 and the corresponding transverse plate 15 cooperate to limit the sliding sleeve 13 to one side of the rotating plate 11. At this time, the inner wall of the sliding sleeve 13 no longer limits the outer end of the insertion rod 16, and then the rotating sleeve 9 is rotated. The rotating sleeve 9 will drive the multiple insertion rods 16 set on the side wall to move, and then the side wall of the slot 17 squeezes one end of the insertion rod 16. Due to the rounded corners at the edge of the slot 17 and the end of the insertion rod 16, one end of the insertion rod 16 slides out of the slot 17, and the other end of the insertion rod 16 will drive the reset The spring 18 is stretched, and the rotating sleeve 9 drives the spiral block 6 to rotate through the connecting plate 5, and then the spiral block 6 will slide along the spiral groove 4. Due to the spiral structure of the spiral groove 4 and the clamping frame 20, the sliding sleeve 3 is limited. Then the sliding sleeve 3 drives the spiral groove 4 and the sliding groove 8 to slide. Due to the special structural design of the sliding groove 8, the sliding rod 10 drives the clamping frame 20 to slide out of the clamping groove 19, and then the fixed sleeve 2 and the fixed rod 7 are pulled to both sides respectively, and the fixed sleeve 2 and the fixed rod 7 can be removed. Then the first clamping frame 30 and the second clamping frame 31 are pulled to both sides, so that the first clamping frame 30 and the second clamping frame 31 are opened along the rotating shaft 32, and then the first clamping frame 30 and the second clamping frame 31 are removed, and then the connecting frame 25 and the filter screen 28 are installed. The filter screen 28 is then replaced and thoroughly cleaned. After replacement and thorough cleaning, the guide block 26, the connecting frame 25 and the fixing frame 24 are reassembled together, and the filter screen 28 is surrounded and arranged on the outside of the connecting frame 25. The first and second brackets 30, 31 are used to limit the filter screen 28 again, and the brackets 33, 34 are engaged with the clamping ring 34 in the clamping groove 33. The fixing rod 7 is then passed through the reserved holes on the first and second brackets 30, 31, and the fixing sleeve 2 is then fitted onto the outside of the fixing rod 7 from the other side.Then rotate the rotating sleeve 9 in the opposite direction, so that the rotating sleeve 9 drives the insertion rod 16 and the connecting plate 5 to rotate, and then the connecting plate 5 will drive the spiral block 6 to rotate, and the sliding sleeve 3 will slide and reset through the cooperation of the threaded block and the spiral groove 4, and then the sliding sleeve 3 will drive the sliding groove 8 to reset, and then the sliding rod 10 will drive the locking frame 20 to re-engage in the locking groove 19, at this time the reset spring 18 just drives the insertion rod 16 to reset, so that one end of the insertion rod 16 is reinserted into the original slot 17, and the rotating plate 11 is rotated again at this time, so that the rotating plate 11 drives the yield groove 12 to move, and when the yield groove 12 moves to the corresponding position with the cross plate 15, the push spring 21 pushes the sliding sleeve 13 to slide and reset, and then The sliding sleeve 13 will drive the longitudinal plate 14 and the transverse plate 15 to return to their original position. When the push spring 21 is fully reset, the other two transverse plates 15 will move to the two sides of the rotating plate 11 respectively.

At this time, the longitudinal plate 14 and the corresponding two transverse plates 15 will cooperate to limit the sliding sleeve 13 to one side of the rotating plate 11, so that the sliding sleeve 13 will not slide easily. Then the inner wall of the sliding sleeve 13 will limit the outer end of the insertion rod 16 again, thereby preventing the insertion rod 16 from moving. Then the insertion rod 16 and the slot 17 cooperate to limit the rotating sleeve 9, preventing the rotating sleeve 9 from rotating, thereby preventing accidental unlocking, thereby ensuring the stability of the fixed structure.
