TECHNICAL FIELD
[0001] The utility model relates to the technical field of regenerating rubber feed, and specifically relates to airtight feed device of regenerating rubber dynamic desulfurization system. BACKGROUND
[0002] In the production process of regenerating rubber, the dynamic desulfurization system is one of the key equipment, which mainly functions to desulfurize waste rubber through high temperature and high pressure conditions to restore its plasticity. The airtightness of the feed device, as an important component of the dynamic desulfurization system, directly affects the desulfurization effect, production safety and environmental friendliness.
[0003] At present, the existing regenerating rubber dynamic desulfurization system feed device often has the problem of poor airtightness due to defects in the structure design during the feeding process. During feeding, the high temperature and high pressure environment inside the desulfurization system can easily cause harmful gases (such as hydrogen sulfide) to leak from the feed port, which not only harms the health of the operators, but also pollutes the surrounding environment. At the same time, gas leakage can cause the internal pressure of the system to drop, and in order to maintain the pressure conditions required for desulfurization, more energy needs to be consumed to supplement the pressure, resulting in a large waste of energy. In addition, external air can also enter the desulfurization system through the feed port, affecting the desulfurization reaction and reducing the quality of the regenerating rubber. SUMMARY

At the same time, the purification assembly on the top of the box body can purify the gas generated in the box body before discharging. This structure design realizes the relative closure of the raw material conveying process, reduces the possibility of gas leakage, increases the overall airtightness of the feed device, and improves the safety and environmental friendliness of production.

This cooperation realizes the purification and discharge of the gas in the box body, avoids the direct leakage of harmful gas to the outside, increases the environmental protection performance, and improves the protection of the health of the operators.
[0009] Preferably, a feeding pipe is mounted on the top of the box body, and a cover plate is sealingly mounted on the top end of the feeding pipe.

[0012] The above components achieve the effects that, through the cooperation of the conveying pipe, the rotating shaft, and the spiral blade, the driving assembly drives the rotating shaft to rotate, the rotating shaft drives the spiral blade to rotate in the conveying pipe, and the raw materials entering the conveying pipe from the communication pipe are pushed forward by the spiral blade. The conveying pipe provides a closed channel for raw material conveying, the rotation of the spiral blade realizes the continuous and stable conveying of the raw materials, and the cooperation of the two reduces the gas leakage in the raw material conveying process, increases the air tightness of the conveying process, and improves the efficiency and stability of the raw material conveying.

The spiral guiding assembly 4 includes a conveying pipe 41 connected to the connecting pipe 3. A rotating shaft 42, which is rotatably installed inside the conveying pipe 41 and is connected to a drive assembly 5, is driven by a spiral blade 43. Component 5 drives the rotating shaft 42 to rotate, and the rotating shaft 42 drives the spiral blades 43 to rotate inside the conveying pipe 41.
