Description

Technical Field

[0001] This invention relates to the field of ion exchange resin production technology, and in particular to a feeding mechanism for ion exchange resin production. Background Technology

[0002] Ion exchange resins are solid polymer materials with special chemical structures, commonly used in water treatment, chemical separation, food processing, pharmaceuticals, and other industrial fields. Their main function is to remove certain ions from solutions through surface ion exchange, and they are widely used in processes such as water softening, deionized water production, wastewater treatment, and chemical separation.

[0003] In the prior art, document CN213801677U discloses an automatic feeding mechanism for epoxy resin production. This mechanism, through the configuration of a hydraulic jack, a support column, and a discharge hose, rotatably connects the feeding cylinder to a base. The hydraulic jack pushes the feeding cylinder to rotate around the support column, thereby adjusting the height of the discharge hose. The discharge hose can be freely adjusted according to the position of the inlet of the epoxy resin production equipment, allowing the feeding mechanism to flexibly adjust its height and meet the feeding needs of more production equipment.

[0004] In existing technology, epoxy resin raw materials are conveyed by pouring them into a feeding cylinder through a feed hopper. The production of ion exchange resins requires various raw materials. Depending on their form, solid raw materials are typically packaged in bags, while liquid raw materials are packaged in drums. For example, crosslinking agents are usually in liquid form. In existing technology, when the drummed crosslinking agent is poured into the feed hopper, residual crosslinking agent adhering to the drum wall cannot be completely poured out, resulting in some liquid remaining in the drum. This not only wastes raw materials and increases production costs but also requires operators to spend extra time cleaning, shaking, or inverting the drum to ensure complete liquid drainage, consuming time, reducing overall production line efficiency, and delaying production schedules.

[0005] In summary, the existing technology lacks a technique for fully emptying the barrelled liquid raw materials for ion exchange resins. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a feeding mechanism for ion exchange resin production.

[0008] Preferably, the raw material barrel scraping mechanism includes an electric push rod, which is rotatably connected to the receiving hopper. A scraping rod is fixedly connected to the output end of the electric push rod, and the scraping rod is in sliding contact with the inner wall of the raw material barrel.

One end of one of the rollers passes through the fixed frame and is fixedly connected to a motor B, which is fixedly connected to the fixed frame.

[0011] Preferably, the placement base is fixedly connected with multiple fixing rods in a ring structure, and multiple limiting blocks are slidably fitted at the top of the fixing rods. One end of each limiting block has an inclined surface, and the limiting block is in movable contact with the raw material barrel. A tension spring is fixedly connected to the limiting block, and the other end of the tension spring is fixedly connected to the fixing rod.

[0012] Preferably, a movable ring is provided above the placement seat, the movable ring is slidably coupled with the fixed rod, a plurality of connecting rods are rotatably connected to the movable ring, the other end of the connecting rods is rotatably connected to the limiting block, and a contact head is fixedly connected to one side of the movable ring, the contact head is slidably in contact with the guide block.

[0013] Preferably, the cleaning mechanism includes a rotating frame, which is rotatably connected to the placement seat. A ring rack is fixedly connected to the bottom end of the rotating frame. A driven wheel is meshed and driven on one side of the ring rack. A rotating shaft is fixedly connected to the driven wheel. The rotating shaft is rotatably connected to the placement seat. The other end of the rotating shaft passes through the feeding belt and is fixedly connected to a driving wheel. The driving wheel meshes and drives the fixed rack.

[0014] Preferably, a suction hood is fixedly connected to the rotating frame, an exhaust fan is installed inside the suction hood, multiple brush rods are fixedly connected to the side of the suction hood facing the raw material barrel, the brush rods are in movable contact with the outer wall of the raw material barrel, and a filter element is installed inside the suction hood.

By utilizing the combination of a feeding belt, a fixed rack, a suction hood, a brush rod, and an exhaust fan, the outer wall of the raw material barrel can be automatically cleaned during its movement. This not only improves production efficiency and reduces manual intervention, but also effectively ensures the cleanliness and hygiene of the outer wall of the raw material barrel, preventing potential contamination during the raw material dumping process and ensuring the stability and safety of product quality.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The ion exchange resin production feeding mechanism shown includes a base 1, a spiral feeding pipe 2 fixedly mounted on the base 1, a receiving hopper 3 fixedly connected to the spiral feeding pipe 2, a raw material barrel scraping mechanism 4 rotatably connected to the receiving hopper 3, a fixing frame 5 fixedly connected to one side of the base 1, a feeding belt 6 rotatably connected to the fixing frame 5, a plurality of placement seats 7 fixedly connected to the feeding belt 6, a raw material barrel 8 placed on the placement seat 7, and a cleaning mechanism 9 rotatably connected to the placement seat 7.

[0031] like Figure 4As shown, the raw material barrel scraping mechanism 4 includes an electric actuator 401, which is rotatably connected to the receiving hopper 3. A scraping rod 402 is fixedly connected to the output end of the electric actuator 401, and the scraping rod 402 is in sliding contact with the inner wall of the raw material barrel 8. A motor A403 is fixedly connected to the bottom end of the electric actuator 401, and the motor A403 is fixedly connected to the spiral feeding pipe 2. The scraping rod 402 has a spiral structure. A rubber strip is fixedly connected to the scraping rod 402. The rubber strip has good flexibility, which can effectively prevent excessive wear when the scraper rod 402 comes into direct contact with the barrel wall. This not only protects the barrel wall surface and extends the service life of the equipment, but also reduces the damage that may be caused by friction from hard objects. The elasticity and friction of the rubber strip help to scrape off the crosslinking agent residue on the barrel wall. The electric push rod 401 drives the connected scraper rod 402 to be inserted into the raw material barrel 8. Then, the motor A403 drives the connected scraper rod 402 to rotate, so that the scraper rod 402 can scrape off the crosslinking agent attached to the inner wall of the raw material barrel 8.

[0032] By setting a raw material barrel scraping mechanism 4 inside the receiving hopper 3, the scraping rod 402 with a rotating spiral structure can scrape off the residual crosslinking agent adhering to the barrel wall. This not only avoids waste of raw materials and ensures full pouring of crosslinking agent, but also effectively improves the efficiency and cleanliness of the production line, reduces pollution and cross-contamination, lowers costs, and improves material flowability and product consistency.

[0033] like Figure 5 As shown, a fixed rack 501 is fixedly connected to the fixed frame 5, a guide block 502 is fixedly connected to the fixed frame 5, the guide block 502 has an inclined surface, and a worktable 503 is fixedly connected to the fixed frame 5. The inclined surface on the guide block 502 drives the contact head 706 to move.

[0034] like Figure 6 As shown, both ends of the feeding belt 6 are equipped with friction-driven rollers 601. The two ends of the rollers 601 are rotatably connected to the fixed frame 5. One end of one roller 601 passes through the fixed frame 5 and is fixedly connected to a motor B602. The motor B602 is also fixedly connected to the fixed frame 5. The motor B602 drives the connected roller 601 to rotate, which in turn drives the feeding belt 6 to rotate, causing the feeding belt 6 to move the raw material bucket 8 towards the receiving hopper 3.

[0035] like Figure 7As shown, multiple fixing rods 701 are fixedly connected in a ring structure on the placement base 7. Multiple limiting blocks 702 are slidably fitted onto the top of each fixing rod 701. One end of each limiting block 702 has an inclined surface. The limiting block 702 is in movable contact with the raw material bucket 8. A tension spring 703 is fixedly connected to the limiting block 702, and the other end of the tension spring 703 is connected and fixedly fixed to the fixing rod 701. Under the action of the tension spring 703, the limiting block 702 will limit and fix the raw material bucket 8. The inclined surface at one end of the limiting block 702 facilitates the placement of the raw material bucket 8 onto the placement base 7.

[0036] A movable ring 704 is provided above the placement base 7. The movable ring 704 is slidably engaged with the fixed rod 701. Multiple connecting rods 705 are rotatably connected to the movable ring 704. The other end of the connecting rod 705 is rotatably connected to the limiting block 702. A contact head 706 is fixedly connected to one side of the movable ring 704. The contact head 706 is in slidable contact with the guide block 502. When the contact head 706 contacts the inclined surface of the guide block 502, it will cause the contact head 706 to drive the connected movable ring 704 to move. This causes the movable ring 704 to drive the limiting block 702 to retract via the connecting rods 705, allowing the raw material barrel 8 to fall automatically.

[0037] like Figure 8 As shown, the cleaning mechanism 9 includes a rotating frame 901, which is rotatably connected to the placement seat 7. A ring rack 902 is fixedly connected to the bottom end of the rotating frame 901. A driven wheel 903 is meshed and driven on one side of the ring rack 902. A rotating shaft 904 is fixedly connected to the driven wheel 903. The rotating shaft 904 is rotatably connected to the placement seat 7. The other end of the rotating shaft 904 passes through the feeding belt 6 and is fixedly connected to a driving wheel 905. The driving wheel 905 is meshed and driven by the fixed rack 501.

[0038] A suction hood 906 is fixedly connected to the rotating frame 901. An exhaust fan 907 is installed inside the suction hood 906. Multiple brush rods 908 are fixedly connected to the side of the suction hood 906 facing the raw material container 8. The brush rods 908 are in movable contact with the outer wall of the raw material container 8. A filter element is installed inside the suction hood 906. The drive wheel 905 meshes with the fixed rack 501, causing the drive wheel 905 to rotate. The rotation of the drive wheel 905 drives the rotating shaft 904 to rotate, which in turn drives the connected driven wheel 903 to rotate. The driven wheel 903 then meshes with the ring rack 902, which in turn drives the connected rotating frame 901 to rotate. This allows the brush rods 908 on the suction hood 906 to clean the outer wall of the raw material container 8. Simultaneously, the exhaust fan 907 draws the dust generated during cleaning into the suction hood 906, where it is filtered by the filter element.

[0039] like Figure 3As shown, a feed pipe 101 is fixedly connected to the base 1. A baffle plate 102 is rotatably connected to the bottom opening of the feed pipe 101. A worm gear 103 is fixedly connected to the baffle plate 102. A worm 104 is meshed and driven on one side of the worm gear 103. The worm 104 is rotatably connected to the feed pipe 101. Rotating the worm 104 causes the worm gear 103 to rotate, which in turn causes the baffle plate 102 to move away.

[0040] Working principle: When the crosslinking agent is fed during the production of ion exchange resin, the raw material barrel 8 is first removed from the workbench 503 by hand and placed on the placement seat 7. At this time, under the action of the tension spring 703, the limiting block 702 will limit and fix the raw material barrel 8. Then, the motor B602 drives the connected roller shaft 601 to rotate, which drives the feeding belt 6 to rotate, and the feeding belt 6 drives the raw material barrel 8 to move towards the receiving hopper 3.

[0041] When the raw material barrel 8 moves, the drive wheel 905 meshes with the fixed rack 501, causing the drive wheel 905 to rotate. When the drive wheel 905 rotates, it drives the rotating shaft 904 to rotate, which in turn drives the connected driven wheel 903 to rotate. At this time, the driven wheel 903 meshes with the ring rack 902, which in turn drives the connected rotating frame 901 to rotate. This allows the brush rod 908 on the suction hood 906 to clean the outer wall of the raw material barrel 8. At the same time, the exhaust fan 907 draws the dust generated during cleaning into the suction hood 906 and filters it through the filter element.

[0042] After the raw materials are poured above the moving receiving hopper 3 of the raw material barrel 8, the electric push rod 401 drives the connected scraper rod 402 to be inserted into the raw material barrel 8. Then, the motor A403 drives the connected scraper rod 402 to rotate, so that the scraper rod 402 can scrape off the crosslinking agent attached to the inner wall of the raw material barrel 8, ensuring full pouring.

[0043] Then, when the feeding belt 6 continues to move the raw material barrel 8, when the contact head 706 contacts the inclined surface of the guide block 502, the contact head 706 will drive the connected movable ring 704 to move, so that the movable ring 704 will drive the limit block 702 to retract through the connecting rod 705, so that the raw material barrel 8 can fall automatically into the feeding pipe 101, and then multiple raw material barrels 8 will fall down in sequence and be stacked.

[0044] When it is necessary to remove the raw material barrel 8 from the discharge pipe 101, move the trolley below the discharge pipe 101, and then rotate the worm gear 104 so that the worm gear 104 drives the worm wheel 103 to rotate, so that the worm wheel 103 drives the connected barrel baffle 102 to move away, so that the raw material barrel 8 can fall onto the trolley for easy transfer.
