Vulcanization mechanical electrical heating device

Abstract

The invention discloses an electric heating device for a vulcanizing machine. An electric heating film which generates heat as a whole is used as a heating element. There are heat transfer parts on one or both sides of the electric heating film. Due to the large-area uniform thermal field and small thermal inertia of the electrothermal film, the electrothermal film and the heat transfer element can be in close contact on the entire area without gaps, so the thermal efficiency is high, the temperature rises faster, and the surface temperature difference of the heat transfer element is small. The heat transfer part does not need to drill elongated holes and weld steam channels, so the structure is relatively simple and the processing is relatively easy. For the tire vulcanizer, the electric heating plate is used to replace the steam heating plate, and the tire factory can change the original high-power boiler to a low-power boiler and cancel most of the steam supply pipe network, thereby greatly reducing pollution sources and obtaining great energy saving benefit. Unlike the steam heating device, the electric heating device is equipped with a group of valves, which can reduce the cost, prevent the space around the machine from being too crowded, and facilitate installation and maintenance.

Description

(1) Technical field: [0001] The present invention relates to a heating device for rubber and tire vulcanization equipment. (2) Background technology: [0002] The heating elements used in the electric heating plate of the existing rubber flat vulcanizing machine are all tubular, and the electric heating pipe is inserted into the hole of the heating plate. The temperature difference is large. The hot plate of the existing hot plate type tire vulcanizer is heated by steam, and the processing of the steam hot plate is complicated, and it is easy to leak and be damaged by rust. The hot plate needs to be equipped with complicated steam supply and condensate drainage pipelines, which take up a lot of space around the vulcanizer, making equipment maintenance extremely inconvenient. The condensed water needs to take away part of the heat, and the boiler and its pipelines that produce steam are the places where the tire factory pollutes the environment and consumes high energy.

Problems solved by technology

[0002] The heating elements used in the electric heating plate of the existing rubber flat vulcanizing machine are all tubular. When the electric heating tube is inserted into the hole of the heating plate, it is difficult for the electric heating tube to be in close contact with the inner wall of the hole, so the thermal efficiency is not high, the temperature rises slowly, and the surface of the heating plate large temperature difference

The hot plate of the existing hot plate type tire vulcanizer is heated by steam, and the processing of the steam hot plate is relatively complicated, and it is easy to leak, rust and damage

The hot plate needs to be equipped with complex steam supply and condensate discharge pipelines, which will occupy a large space around the vulcanizer, making equipment maintenance extremely inconvenient
