Abstract
Description
Technical Field
[0001] This utility model relates to the field of melting kettle technology, specifically a highly sealed melting kettle. Background Technology
[0002] During long-term storage and use, rubber and its products gradually become sticky, hard, brittle, or cracked due to the effects of heat, oxygen, ozone, variable-valence metal ions, mechanical stress, light, high-energy radiation, as well as the erosion of other chemicals and mold. This phenomenon of declining physical and mechanical properties and reduced elasticity over time is called aging. As the aging process progresses, the properties of rubber and its products gradually deteriorate until they completely lose their usability. Therefore, certain chemical substances need to be added to rubber and its products to improve their resistance to the aforementioned destructive effects, delay or inhibit the aging process, and thus extend the storage period and service life of rubber and its products. These substances are called antioxidants, and a melting tank is required when processing antioxidants.
[0003] Raw materials are fed into the melting kettle body through the feed cylinder. After feeding is completed, the feed cylinder needs to be sealed with a cover plate. However, some existing cover plate installation methods use multiple bolts to connect to the feed cylinder, which is not convenient for personnel to operate and does not achieve the effect of quick installation, thus reducing practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a high-sealing melting kettle, including a melting kettle body 1, a feeding cylinder 2 installed on the top of the melting kettle body 1, a hollow cover plate 3 on the top of the feeding cylinder 2, multiple positioning grooves 24 on the top of the feeding cylinder 2, multiple positioning blocks 23 fixedly connected to the bottom of the hollow cover plate 3, the positioning blocks 23 being disposed inside the positioning grooves 24, a U-shaped handle 5 fixedly connected to the top of the hollow cover plate 3, a sealing structure between the hollow cover plate 3 and the feeding cylinder 2, multiple sliding grooves 15 on the outer side of the hollow cover plate 3, a rotating rod 16 rotatably connected inside the hollow cover plate 3, a worm gear 28 fixedly connected to the outer side of the rotating rod 16, a worm 29 meshing with the outer side of the worm gear 28, one end of the worm 29 passing through the inner side of the hollow cover plate 3 and rotatably connected to the hollow cover plate 3, the worm 29... A throttle is installed at the end. A large gear 17 is fixedly connected to the outside of the rotating rod 16. Multiple small gears 18 are meshed with the outside of the large gear 17. A threaded rod 19 is fixedly connected to the inside of the small gears 18. The threaded rod 19 is rotatably connected to the inside of the hollow cover plate 3. A lifting plate 20 is threadedly connected to the outside of the threaded rod 19. One end of the lifting plate 20 passes through the sliding groove 15 and is slidably connected to the hollow cover plate 3. A cylindrical rod 21 is fixedly connected to the bottom of one end of the lifting plate 20. A round block 22 is fixedly connected to the bottom of the cylindrical rod 21. An arc-shaped block 14 is provided on the outside of the cylindrical rod 21. An arc-shaped groove is opened on the inside of the arc-shaped block 14. The cylindrical rod 21 is set inside the arc-shaped groove. The arc-shaped block 14 is fixedly connected to the outside of the feed cylinder 2. The top of the round block 22 is in contact with the bottom of the arc-shaped block 14. A support structure is provided on the outside of the hollow cover plate 3.
[0023] The sealing structure includes an adapter groove 27 and an adapter block 25. The adapter groove 27 is opened at the top of the feed cylinder 2, and the adapter block 25 is disposed inside the adapter groove 27. Two sealing gaskets 26 are disposed on the outside of the adapter block 25, and both sealing gaskets 26 are in contact with the feed cylinder 2.
[0024] Specifically, the hollow cover plate 3 is moved downward by the U-shaped handle 5. Rotating the hollow cover plate 3 causes multiple cylindrical rods 21 to enter multiple arc-shaped grooves, while multiple positioning blocks 23 enter multiple positioning grooves 24. Then, rotating the handle causes the worm gear 29 to mesh with the worm wheel 28. The worm wheel 28 drives the large gear 17 to rotate via the rotating rod 16. The large gear 17 meshes with multiple small gears 18, which in turn drive multiple threaded rods 19 to rotate. The threaded rods 19 are threadedly connected to multiple lifting plates 20. The lifting plates 20 then drive multiple round blocks 22 upward via the cylindrical rods 21. The round blocks 22 contact multiple arc-shaped blocks 14, thus achieving a quick connection between the hollow cover plate 3 and the feed cylinder 2, facilitating personnel operation.
[0025] Since the adapter block 25 is located inside the adapter groove 27, the two sealing gaskets 26 provided on the outside of the adapter block 25 can better improve the sealing performance between the hollow cover plate 3 and the feed cylinder 2.
[0026] Example: Figure 1 - Figure 3 As shown, the support structure includes a ring frame 4, which is rotatably connected to the outside of the hollow cover plate 3. A T-shaped plate 6 is fixedly connected to the outside of the ring frame 4. A fixing plate 7 is provided at one end of the T-shaped plate 6. The fixing plate 7 is fixedly connected to the top of the melting kettle body 1. A T-shaped groove 8 is opened on one side of the fixing plate 7. The T-shaped plate 6 is set inside the T-shaped groove 8 and is slidably connected to the fixing plate 7. The support structure also includes a push plate 9 and two sliding rods 12. The push plate 9 is set on one side of the fixing plate 7. A limit block 10 is fixedly connected to one side of the push plate 9. The limit block 10 is adapted to the U-shaped handle 5. The two sliding rods 12 are fixedly connected to one side of the fixing plate 7. One end of each sliding rod 12 passes through the push plate 9 and is slidably connected to the push plate 9. A stop block 11 is fixedly connected to one end of each sliding rod 12. The two stop blocks 11 are in contact with the push plate 9. A spring 13 is sleeved on the outside of each sliding rod 12. The two ends of the two springs 13 are fixedly connected to the fixing plate 7 and the push plate 9, respectively.
[0027] Specifically, when the hollow cover plate 3 is disassembled and needs to be placed, the push plate 9 is pressed down, the two springs 13 are elastically compressed, the push plate 9 slides on the two slide rods 12, and the position of the limiting block 10 is adjusted. When the U-shaped handle 5 moves upward to a suitable position, the push plate 9 is loosened, the two springs 13 are elastically reset, and the limiting block 10 is then inserted into the U-shaped handle 5 to support the hollow cover plate 3.
