Embodiment Construction

[0011] Such as figure 1 As shown, the autoclave of the present invention includes a tank cover 1 and a tank body 2, and the tank cover 1 is arranged on the top of the tank body 2; an external pressure steam inlet 3, an external pressure steam exhaust port 4, an internal pressure inlet Steam port 5, internal pressure exhaust port 6, air inlet I 7; tank body 2 is provided with a tubular mold 8 that participates in vulcanization, the bottom of the mold 8 is connected to the tank body 2 through a support plate 9, and an upper seal is installed on the top Plate 10, a rubber sleeve 11 at the same height as the mold 8 is installed on the periphery of the mold 8. After installation, the mold 8, the rubber sleeve 11, the upper sealing plate 10, and the support plate 9 divide the inside of the tank body 2 into an inner cavity 12 and an outer cavity 13. The inner cavity 12 belongs to the space surrounded by the mold 8, the upper sealing plate 10, and the support plate 9, which is just in...

Abstract

The invention discloses a vulcanizing boiler. By utilizing a double-layer coil pipe attached on the inner wall of the vulcanizing boiler, saturated steam in an outer pipe and an inner cavity can be communicated with each other to heat an inner pipe, high-pressure compressed air is input to an outer cavity through the inner pipe, and thus the continuous heating of high-pressure compressed air in the outer cavity can be realized during the vulcanization process; therefore, the purpose of increasing the vulcanizing pressure can be realized, the outer cavity can be in a high-pressure low-temperature state, the vulcanizing pressure is increased, and the working pressure of the high-pressure compressed air can be 1.6 MPa which is nearly 0.9 MPa higher than the common vulcanizing condition; therefore the fluidity, the tooth filling property and the compactness of the product and the binding property among components are improved, and the defective rate is reduced.

Description

technical field [0001] The invention relates to vulcanization equipment for rubber products, in particular to a vulcanization tank. Background technique [0002] The vulcanization process of rubber requires a certain temperature (140-150°C), pressure (the unit pressure of general rubber transmission belt vulcanization is 2.0-2.2Mpa), and time. The traditional transmission belt vulcanization tank is generally composed of: tank cover, tank body, internal and external pressure chambers, intake and exhaust systems, and control systems. The vulcanized medium generally uses saturated steam. The vulcanization pressure of the transmission belt is obtained by the pressure difference between the inner pressure chamber and the outer pressure chamber. The inner pressure cavity and the outer pressure cavity are formed by separating the inside of the tank body by the mold and the upper sealing plate. The higher the pressure of saturated steam, the higher the corresponding temperature, ...
