Description

Technical Field

[0001] The present invention relates to the technical field of ion exchange resin production, and particularly to a feeding mechanism for ion exchange resin production. Background Art

[0002] Ion exchange resin is a solid polymer material with a special chemical structure, usually used in other industrial fields such as water treatment, chemical separation, food processing, and pharmaceuticals. Its main function is to remove certain ions in the solution through surface ion exchange, and it is widely used in processes such as water softening, deionized water production, wastewater treatment, and chemical separation.

[0003] In the prior art, the document with the publication number CN213801677U provides an automatic feeding mechanism for epoxy resin production. This mechanism enables the feeding cylinder to be rotatably connected to the base by setting a hydraulic jack, a support column, and a feeding hose. The hydraulic jack can push the feeding cylinder to rotate around the support column, thereby adjusting the height of the feeding hose. The feeding hose can be freely adjusted according to the position of the feeding port on the epoxy resin production equipment, making this feeding mechanism flexible in height adjustment to meet the feeding requirements of more production equipment.

[0004] When the prior art is in use, the epoxy resin raw materials are poured into the feeding cylinder through the feed hopper for transportation. In the production process of ion exchange resin, multiple raw materials are required. According to the different forms of the raw materials, solid raw materials are usually packed in bags, and liquid raw materials are packed in barrels. For example, the crosslinking agent usually exists in liquid form. When pouring the crosslinking agent in a barrel into the feed hopper in the prior art, the residual crosslinking agent adhering to the barrel wall cannot be completely poured out, resulting in some liquid remaining in the barrel. This not only causes waste of raw materials and increases production costs, but also requires the operator to spend extra time cleaning, shaking, or inverting the barrel to ensure that the liquid completely flows out, occupying time, reducing the overall efficiency of the production line, and delaying the production progress.

[0005] In summary, in the prior art, there is a lack of technology for fully pouring out the liquid raw materials in barrels for ion exchange resin. Summary of the Invention

Detailed implementation manners

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

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

[0031] As Figure 4As shown in the figure, the scraping mechanism 4 of the raw material barrel includes an electric push rod 401. The electric push rod 401 is rotatably connected to the receiving hopper 3 in a penetrating manner. The output end of the electric push rod 401 is fixedly connected with a scraping rod 402. The scraping rod 402 is in sliding contact with the inner wall of the raw material barrel 8. The bottom end of the electric push rod 401 is fixedly connected with a motor A 403. The motor A 403 is fixedly connected with the spiral feeding pipe 2. The scraping rod 402 is arranged in a spiral structure. A rubber strip is fixedly connected to the scraping rod 402. The rubber strip has good flexibility, which can effectively avoid excessive wear when the scraping rod 402 directly contacts the barrel wall. It not only protects the surface of the barrel wall and extends the service life of the equipment, but also reduces the damage that may be caused by the friction of hard objects. The elasticity and friction of the rubber strip help to scrape off the residual cross-linking agent on the barrel wall. The electric push rod 401 drives the connected scraping rod 402 to insert into the raw material barrel 8, and then the motor A 403 drives the connected scraping rod 402 to rotate, so that the scraping rod 402 can scrape off the cross-linking agent attached to the inner wall of the raw material barrel 8.

[0032] By arranging the scraping mechanism 4 of the raw material barrel in the receiving hopper 3 and using the rotating scraping rod 402 arranged in a spiral structure, the residual cross-linking agent attached to the barrel wall can be scraped off. It can not only avoid waste of raw materials, ensure the full pouring of the cross-linking agent, but also effectively improve the efficiency and cleanliness of the production line, reduce pollution and cross-contamination, reduce costs, and improve the fluidity of materials and product consistency.

[0033] As Figure 5 shown in the figure, a fixed rack 501 is fixedly connected to the fixed frame 5. A guide block 502 is fixedly connected to the fixed frame 5. An inclined surface is provided on the guide block 502. A workbench 503 is fixedly connected to the fixed frame 5. The inclined surface provided on the guide block 502 realizes driving the contacting contact head 706 to move.

[0034] As Figure 6 shown in the figure, roller shafts 601 are frictionally driven inside both ends of the feeding belt 6. Both ends of the roller shafts 601 are rotatably connected to the fixed frame 5. One end of one of the roller shafts 601 passes through the fixed frame 5 and is fixedly connected with a motor B 602. The motor B 602 is fixedly connected with the fixed frame 5. The motor B 602 drives the connected roller shaft 601 to rotate, so that the roller shaft 601 drives the feeding belt 6 to rotate, and the feeding belt 6 drives the raw material barrel 8 to move in the direction of the receiving hopper 3.

[0035] As Figure 7As shown, a plurality of fixing rods 701 are fixedly connected in a ring structure on the placing seat 7. The top ends of the fixing rods 701 are slidably fitted with a plurality of limiting blocks 702. One end of the limiting block 702 is provided with an inclined surface. The limiting block 702 is in movable contact with the raw material barrel 8. A tension spring 703 is fixedly connected to the limiting block 702, and the other end of the tension spring 703 is fixedly connected to the fixing rod 701. Under the action of the tension spring 703, the limiting block 702 will limit and fix the raw material barrel 8. One end of the limiting block 702 is provided with an inclined surface, which facilitates the placement of the raw material barrel 8 on the placing seat 7.

[0036] An activity ring 704 is arranged above the placing seat 7. The activity ring 704 is slidably fitted with the fixing rod 701. A plurality of connecting rods 705 are rotatably connected to the activity ring 704, and the other ends of the connecting rods 705 are rotatably connected to the limiting block 702. A contact head 706 is fixedly connected to one side of the activity ring 704, and the contact head 706 is in sliding contact with the guiding block 502. When the contact head 706 contacts the inclined surface of the guiding block 502, the contact head 706 will drive the connected activity ring 704 to move, so that the activity ring 704 drives the limiting block 702 to retract through the connecting rod 705, enabling the raw material barrel 8 to fall automatically.

[0037] As Figure 8 As shown, the cleaning mechanism 9 includes a rotating frame 901. The rotating frame 901 is rotatably connected to the placing seat 7. A ring-shaped 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-shaped rack 902. A rotating shaft 904 is fixedly connected to the driven wheel 903. The rotating shaft 904 is rotatably connected through the placing 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 with the fixed rack 501.

[0038] A suction hood 906 is fixedly connected to the rotating frame 901. An exhaust fan 907 is installed in the suction hood 906. A plurality of brush rods 908 are fixedly connected to the side of the suction hood 906 facing the raw material barrel 8. The brush rods 908 are in movable contact with the outer wall of the raw material barrel 8. A filter element is installed in the suction hood 906. The driving wheel 905 will be meshed with the fixed rack 501, so that the driving wheel 905 rotates. When the driving wheel 905 rotates, it will drive the rotating shaft 904 to rotate, so that the rotating shaft 904 drives the connected driven wheel 903 to rotate. At this time, the driven wheel 903 will be meshed with the ring-shaped rack 902. At this time, the ring-shaped rack 902 will drive the connected rotating frame 901 to rotate, so that the brush rods 908 on the suction hood 906 can clean the outer wall of the raw material barrel 8. At the same time, the exhaust fan 907 is used to suck the dust generated by cleaning into the suction hood 906 and filter it through the filter element.

[0039] As Figure 3As shown in the figure, a blanking pipe 101 is fixedly connected to the base 1. A retaining bucket plate 102 is rotatably connected to the bottom opening of the blanking pipe 101. A worm gear 103 is fixedly connected to the retaining bucket plate 102. A worm 104 is meshed and driven on one side of the worm gear 103, and the worm 104 is rotatably connected to the blanking pipe 101. Rotate the worm 104 to drive the worm gear 103 to rotate, so that the worm gear 103 drives the connected retaining bucket plate 102 to move away.

[0040] Working principle: When feeding the crosslinking agent during the production of ion exchange resin, first manually remove the raw material bucket 8 from the workbench 503 and place it on the placement seat 7. At this time, under the action of the tension spring 703, the limit block 702 will limit and fix the raw material bucket 8. Then use the motor B602 to drive the connected roller 601 to rotate, so that the roller 601 drives the feeding belt 6 to rotate, and the feeding belt 6 drives the raw material bucket 8 to move in the direction of the receiving hopper 3;

[0041] When the raw material bucket 8 moves, the driving wheel 905 will mesh with the fixed rack 501, so that the driving wheel 905 rotates. When the driving wheel 905 rotates, it will drive the rotating shaft 904 to rotate, so that the rotating shaft 904 drives the connected driven wheel 903 to rotate. At this time, the driven wheel 903 will mesh with the annular rack 902. At this time, the annular rack 902 will drive the connected rotating frame 901 to rotate, so that the brush rod 908 on the suction hood 906 can clean the outer wall of the raw material bucket 8. At the same time, use the exhaust fan 907 to suck the dust generated by cleaning into the suction hood 906 and filter it through the filter element;

[0042] After the raw material in the raw material bucket 8 is poured above the receiving hopper 3, use the electric push rod 401 to drive the connected scraping rod 402 to insert into the raw material bucket 8, and then use the motor A403 to drive the connected scraping rod 402 to rotate, so that the scraping rod 402 can scrape off the crosslinking agent attached to the inner wall of the raw material bucket 8 to ensure full pouring;

[0043] Then when the feeding belt 6 continues to drive the raw material bucket 8 to move, when the contact head 706 touches the inclined surface of the guide block 502, it will drive the connected movable ring 704 to move, so that the movable ring 704 drives the limit block 702 to retract through the connecting rod 705, so that the raw material bucket 8 can automatically fall into the blanking pipe 101, and then multiple raw material buckets 8 fall in sequence for stacking;

[0044] When it is necessary to take out the raw material bucket 8 in the blanking pipe 101, move the trolley under the blanking pipe 101, and then rotate the worm 104 to drive the worm gear 103 to rotate, so that the worm gear 103 drives the connected retaining bucket plate 102 to move away, so that the raw material bucket 8 can fall onto the trolley for convenient transportation.
