Description

Technical Field

[0001] This utility model relates to the field of vapor phase rust inhibitor processing and granulation technology, specifically a twin-screw granulator for manufacturing and processing vapor phase rust inhibitors. Background Technology

[0002] Vapor phase corrosion inhibitor film is a new generation of innovative high-tech product based on the combination of polymer materials and VCI vapor phase corrosion inhibitor technology. After the rust-proof items are packaged and sealed with this film, the VCI contained in the film begins to sublimate and volatilize, releasing rust-proof gas factors. These factors diffuse and penetrate to the surface of the rust-proof items and are adsorbed onto them, forming a dense protective film layer with a single molecule thickness. This isolates the various factors that induce corrosion from contacting the surface of the rust-proof items, thereby effectively preventing the formation of rust. When manufacturing vapor phase corrosion inhibitor film, a twin-screw granulator is required to process the raw materials.

[0003] However, existing twin-screw granulators are inconvenient for processing raw materials during feeding, resulting in excessively large raw material volumes. This affects the subsequent heating and granulation effect, reducing production efficiency. Therefore, to avoid the aforementioned technical problems, it is indeed necessary to provide a twin-screw granulator for the production and processing of vapor phase rust inhibitors to overcome the defects in the existing technology.

[0034] The feeding and crushing mechanism 4 includes a feeding hopper 401, a crushing cylinder 402, a guide plate 403, a vertical frame 404, a crushing channel 405, a connecting rod 406, a crushing roller 407, and a drive motor 408.

[0035] A feed hopper 401 is clamped at one side of the top of the twin-screw granulation channel 2. A crushing cylinder 402 is bolted to the top of the feed hopper 401. Guide plates 403 are symmetrically clamped on the inner wall of the crushing cylinder 402. A vertical frame 404 is clamped at the middle position between the two guide plates 403.

[0036] Inside the crushing cylinder 402, at the bottom position corresponding to the guide plate 403, there are symmetrically engaged crushing channels 405, and a connecting rod 406 is symmetrically rotatably connected between the two crushing channels 405.

[0037] The crushing channel 405 is symmetrically connected to the crushing rollers 407 inside. One end of the crushing cylinder 402 is connected to the drive motor 408 by bolts. In order to facilitate the crushing of raw materials, the distance between the two feed hoppers 401 is equal to the width of the inner wall of the crushing channel 405. The two ends of the connecting rod 406 are respectively fixedly connected to one end of the two opposite crushing rollers 407. The drive motor 408 is powered by an external power source.

[0038] A circulating cooling mechanism 5 is provided at the top of the workbench 1, corresponding to the outer position of the twin-screw granulation channel 2. The circulating cooling mechanism 5 includes a cooling box 501, a heat exchange tube 502, a water tank 503, a water supply pipe 504, a water pump 505, an N-type connecting pipe 506, and a return pipe 507.

[0039] A cooling box 501 is snapped onto the top of the workbench 1 at the position corresponding to the outer side of the twin-screw granulation channel 2. Heat exchange tubes 502 are symmetrically snapped onto the inner wall of the cooling box 501 at equal intervals.

[0040] A water tank 503 is provided at the bottom of the workbench 1. A water supply pipe 504 is attached to the bottom of one end of the water tank 503, and a water pump 505 is installed on the outside of the water supply pipe 504. An N-type connecting pipe 506 is attached to the other end of the water supply pipe 504.

[0041] Return pipes 507 are snapped at the top of both ends of the water tank 503. In order to facilitate circulating cooling, both ends of the heat exchange tube 502 pass through one end of the cooling box 501. The outside of the N-type connecting pipe 506 is connected to one end of the heat exchange tube 502, and one end of the return pipe 507 is connected to the other end of the heat exchange tube 502. The water pump 505 is powered by an external power source.

[0042] A pad 6 is bolted to the top of the vertical frame 404. A rotary motor 7 is bolted to the top of the pad 6. A drive rod 8 is snapped onto the bottom of the rotary motor 7. A rotary friction disc 9 is fixedly sleeved on the outside of the drive rod 8. A fixed friction disc 10 is bolted to the inner wall of the feed hopper 401. In order to further improve the crushing effect of the raw materials, the rotary motor 7 is powered by an external power source. The bottom of the fixed friction disc 10 is in contact with the top of the rotary friction disc 9.

[0043] The working principle and usage process of this utility model are as follows: First, the raw material for processing vapor phase rust inhibitor film is fed into the crushing cylinder 402. Then, guided by the guide plate 403, the raw material is fed into the crushing channel 405. At the same time, the drive motor 408 is started to drive the crushing roller 407 to rotate. With the cooperation of the connecting rod 406, the crushing rollers 407 in the two crushing channels 405 rotate synchronously. In addition, because the two adjacent crushing rollers 407 mesh, they can rotate synchronously relative to each other to crush the raw material, reduce the volume of the raw material, facilitate subsequent granulation, and increase the processing efficiency.

[0044] Next, the crushed raw material falls into the feed hopper 401. At the same time, the rotary motor 7 is started to drive the drive rod 8 and the rotary friction disk 9 to rotate. In cooperation with the fixed friction disk 10, the crushed raw material is ground and crushed again, which further reduces the volume of the raw material and increases the time for subsequent granulation processing.

[0045] Finally, the crushed raw material enters the twin-screw granulation channel 2, where it is conveyed and heated for granulation. After granulation, the water pump 505 is started to send water from the water tank 503 into the N-type connecting pipe 506 through the water supply pipe 504, and then evenly to the heat exchange pipes 502 at both ends of the inner wall of the cooling box 501. The twin-screw granulation channel 2 is then cooled down, which shortens the granulation processing time. The water after heat exchange is returned to the water tank 503 through the return pipe 507 for easy circulation and improved resource utilization.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
