Driving belt vulcanizing boiler

Abstract

A transmission belt vulcanizing boiler comprises a gum cover, an inner cavity between a cover plate and a supporting plate, an outer cavity between the gum cover and the transmission belt vulcanizing boiler, a steam inlet and a steam outlet of the inner cavity, and a pressure air inlet and a pressure air outlet of an outer cavity; wherein, the outer cavity is provided with a high temperature steam heating pipe which is provided with a high temperature steam inlet and a high temperature steam outlet. The high temperature steam heating pipe heats the pressure air in the outer cavity, which ensures the temperature requirement of the outer cavity and ensures high heat energy utilization rate. The high temperature steam heating pipe solely regulates the temperature of the outer cavity, thereby the temperature and pressure of the outer cavity being easy to control. The high temperature steam heating pipe is adopted to prevent steam from dissipating. The inner cavity and the outer cavity share a set of steam heating system, thereby saving energy consumption. The steam inlet of the inner cavity is connected with a pumping line, which is beneficial to the full combination of a belt tube and a mould. The transmission belt vulcanizing boiler also has the advantages of raising product vulcanization quality, shortening vulcanization time and saving steam consumption.

Description

technical field [0001] The invention belongs to a vulcanization tank in the field of rubber product processing equipment, in particular to a transmission belt vulcanization tank specially used for vulcanization of rubber transmission belts. Background technique [0002] The vulcanization tanks for rubber transmission belts are not only different in structure from those for rubber rollers or rubber tires, but also the vulcanization process is also different. The vulcanization tank for rubber rollers or rubber tires can have one cavity, while the vulcanization tank for rubber transmission belts needs to have two cavities inside and outside. The inner cavity of the transmission belt vulcanization tank must be fed with hot steam, and the outer cavity must have a certain pressure difference with the inner cavity and maintain a certain temperature. The inner cavity and outer cavity of the traditional drive belt vulcanization tank are filled with steam medium to pressurize and hea...

Problems solved by technology

China Invention Patent No. 96114745.8 "Rubber V-belt vulcanization process and vulcanization tank" pointed out the defects of traditional transmission belt vulcanization tanks such as "higher steam pressure requirements and large steam consumption". Steam, the technical solution of filling the external cavity with compressed air, this technical solution saves steam, but has the defect that the temperature of the external cavity cannot be controlled and affects the normal vulcanization
