Description

Tire vulcanizer capable of heating nitrogen through steam main pipe

Technical Field

The utility model relates to the field of tire vulcanization, in particular to a tire vulcanizing machine for heating nitrogen through a steam main pipe.

Background

At present, the heating mode commonly used for tire vulcanization is as follows: steam + nitrogen. During the vulcanization of the tire, the green tire absorbs a large amount of heat, and after the heat of the steam is released, condensed water appears at the bottom of the lower tire side. At this time, a temperature difference between the upper and lower molds occurs, which results in a difference in the vulcanization degree between the upper and lower molds of the tire.

In order to reduce the temperature difference between the upper and lower molds, new methods are being tried by tire manufacturers. One such method is total nitrogen sulfiding. The full nitrogen vulcanization mode is that nitrogen is heated and directly filled into the capsule. Because the nitrogen does not contain water vapor, condensed water cannot appear in the vulcanization process, so that the temperature difference of the upper die and the lower die of the tire is very small, and the vulcanization degree of the rubber materials of the upper die and the lower die is almost consistent.

The nitrogen gas in the above method is generally heated in the following manner: one or more vulcanizing machines are provided with a nitrogen heating device, and the heated nitrogen is pressurized and filled into the capsule. But with the attendant disadvantage of large upfront investment.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, an object of the present invention is to provide a tire vulcanizer in which nitrogen gas is heated by a steam header, wherein the nitrogen header is provided in an existing steam header of the vulcanizer, and the nitrogen gas in the nitrogen header is heated by high-temperature steam in the steam header, thereby reducing equipment investment.

For the purpose of the utility model, the following technical scheme is adopted for implementation:

a tire vulcanizer for heating nitrogen through a steam main pipe comprises the steam main pipe, the nitrogen main pipe, nitrogen branch pipes and a tire vulcanizer main body; the steam main pipe is internally provided with a nitrogen main pipe, the nitrogen main pipe is connected with a nitrogen branch pipe, and the nitrogen main pipe is connected with the tire vulcanizer main body through the nitrogen branch pipe.

Preferably, the nitrogen main pipe is provided with a plurality of nitrogen branch pipes, and the number of the nitrogen branch pipes is matched with that of the tire vulcanizer main body.

In conclusion, the utility model has the advantages that the nitrogen main pipe is arranged in the existing steam main pipe of the vulcanizing machine, and the high-temperature steam in the steam main pipe is used for heating the nitrogen in the nitrogen main pipe, so that the equipment investment is reduced.

Detailed Description

As shown in FIG. 1, a tire vulcanizer in which nitrogen gas is heated by a steam header comprises a steam header 1, a nitrogen header 2, nitrogen branch pipes 3 and a tire vulcanizer body 4. Set up nitrogen gas house steward 2 in the steam house steward 1, be connected with nitrogen gas branch pipe 3 on the nitrogen gas house steward 2, nitrogen gas house steward 2 passes through nitrogen gas branch pipe 3 and is connected with tire vulcanizer main part 4, heats the nitrogen gas in the nitrogen gas house steward 2 through the high temperature steam in the steam house steward 1, and the nitrogen gas after the heating passes through in nitrogen gas branch pipe 3 gets into tire vulcanizer main part 4.

Preferably, a plurality of nitrogen branch pipes 3 are arranged on the nitrogen main pipe 2, and the number of the nitrogen branch pipes 3 is matched with that of the tire vulcanizer main body 4.

The utility model has the advantages that the nitrogen header pipe 2 is arranged in the existing steam header pipe 1 of the vulcanizing machine, and the high-temperature steam in the steam header pipe 1 is used for heating the nitrogen in the nitrogen header pipe 2, thereby reducing the equipment investment.
