Degassing process suitable for degassing system for tire vulcanization

Abstract

The invention belongs to the technical field of tire processing, and discloses a degassing process suitable for a degassing system for tire vulcanization, which comprises the following steps: sprayinghot water input into a spraying module from a third pipeline unit and a fourth pipeline unit into a tower body, collecting in a degassing module, and introducing superheated steam into the degassingmodule, reheating water collected in the degassing module through superheated steam, and enabling unliquefied steam to rise to heat water mist sprayed by the spraying module, so that oxygen in the water mist is exhausted through an exhaust pipe; and inputting hot water discharged by the degassing module into an inlet of the outer tire inner mold and an inlet of the outer tire outer mold through the water outlet, the first pipeline unit and the second pipeline unit. The pressure of the superheated steam is 1MPa, and the temperature of the superheated steam is 180 DEG C; and the volume ratio ofthe superheated steam to the water sprayed by the spraying module is 1:60. According to the process, a liquid circulation loop is formed between the degassing tower and the outer tire mold, so that cyclic utilization of energy and substances is realized.

Description

technical field [0001] The invention relates to the technical field of tire processing, in particular to a degassing process applicable to a degassing system for tire vulcanization. Background technique [0002] In the process of tire production, the process from raw tire to finished tire needs to go through the vulcanization process. The process of tire vulcanization is completed in the tire processing mold. The processing mold is equipped with water tires or bladders. During the tire vulcanization process , placing the raw tire tire in the processing mold, and filling the water tire with high-pressure hot water, using the expansion pressure of the water tire or the bladder to fill the mold cavity with the tire blank, thereby realizing the production of the tire; [0003] The medium used for tire vulcanization can be superheated water or steam. In general, the medium used for tire vulcanization generally adopts superheated water. pressure, and its heat transfer is uniform,...

Problems solved by technology

[0003] The medium used for tire vulcanization can be superheated water or steam. In general, the medium used for tire vulcanization generally adopts superheated water, Its advantage is that its properties are relatively stable, it can generate high internal pressure, and its heat transfer is uniform, so that the tire can be vulcanized evenly, but its defect is that the oxygen content in the superheated water is high, and it will be damaged during the long-term vulcanization process. The surface of the water tire or bladder placed in the tire processing mold is easy to oxidize and become brittle, resulting in serious damage and high maintenance costs
