Description

Technical Field

[0001] The utility model relates to the technical field of gas collection in vulcanization workshops, and particularly relates to a vulcanization collection hood. Background Art

[0002] Tire vulcanization refers to the vulcanization of the outer tire, and vulcanization die casting is carried out by means of model pressing; before vulcanization, the internal microstructure of the tire is a linear polymer, which is a viscoelastic plastic rubber, easy to deform and with low strength. Through vulcanization, the linear polymer in the plastic rubber undergoes a cross-linking reaction to form a network polymer material, which is macroscopically solidified into a highly elastic rubber with use value; during vulcanization, a water bag or capsule is filled in the green tire, and high-pressure hot water is injected into the water bag. By using the expansion pressure of the water bag or capsule, the green tire is filled with the mold, and the vulcanization heating can heat the rubber raw material to 130°C - 180°C. At this temperature, the rubber material will emit tar-containing and volatile VOCs gases, which will not only damage the environment, but also pollute the production workshop environment and endanger the health of operating workers.

[0003] At present, most of the market adopts the form of an overall fireproof cloth enclosure, which divides the vulcanizers in the production workshop into regions as a whole, sets flue gas discharge pipes in the regions, and uses the principle of exhaust ventilation to extract the waste gas generated by vulcanization in the workshop. Due to the huge workshop space, overall ventilation cannot be achieved, so it is an unorganized emission, which is difficult to meet the environmental protection emission requirements and does not conform to the current environmental protection theme; even if some vulcanization workshops have adopted the form of independent collection hoods, because the collection hoods cannot be linked with the vulcanizers to open and close, the effective collection area is small and the amount of flue gas escaping is large, and organized collection and emission still cannot be achieved; in addition, most of the enclosure materials on the market currently adopt the form of transparent flexible connections, which cannot withstand the high temperature and oil-containing environment in the vulcanization workshop, and the collection frames and flexible connections cannot be removed, often interfering with the vulcanizer body, affecting the daily production operation and maintenance of the vulcanizer equipment. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a vulcanization collection hood, which is used to solve the problem that the collection hoods on the existing market not only cannot remove the collection frames and flexible connections, but also cannot achieve organized collection and emission.
