Thermal cycle degreasing furnace capable of reducing fire damage

Abstract

The invention relates to a thermal cycle degreasing furnace capable of reducing fire damage, and belongs to the field of degreasing furnaces. The thermal cycle degreasing furnace comprises a machine body, wherein the machine body is provided with a degreasing channel, a circulating air flow channel, a circulating fan and a burner; the circulating air flow channel comprises a fire protection section; the fire protection section is located between the circulating fan and the burner; the fire protection section comprises a fixed pipe and a separation pipe which are communicated with each other; the fixed pipe is fixedly connected with the machine body; the separation pipe is detachably connected with the fixed pipe; and a pipe breaking mechanism is further arranged on the fire protection section and used for controlling mutual fixation and separation of the separation pipe and the fixed pipe. According to the thermal cycle degreasing furnace capable of reducing fire damage provided by the invention, after fire occurs in the fixed pipe, some columns of assemblies are triggered to operate, so that the separation pipe is separated from the fixed pipe, a passage for transferring airflow from the circulating fan to a gas pipe is blocked, combustible materials are not conveyed to the direction of a fire burner in the circulating air flow channel any more, flames in the fixed pipe communicating with the burner cannot spread to the circulating fan, and the damage to the circulating fan, the pipeline and other parts during fire burning is reduced.

Description

technical field [0001] The present application relates to the field of degreasing furnaces, in particular to a thermal cycle degreasing furnace which reduces fire damage. Background technique [0002] In the production process of auto parts, some grease substances will adhere to the surface of the workpiece; the degreasing furnace is a mechanical device that uses heating to volatilize the grease on the surface of the workpiece to remove it. The degreasing furnace is equipped with a combustion device and an airflow generator. The combustion device generates heat, the airflow generating device generates airflow, and the airflow carries heat and flows to the workpiece together. [0003] The thermal cycle degreasing furnace is a kind of degreasing furnace, which includes a circulating air flow pipeline and uses a circulating fan as its air flow generating device. The conveying track of the workpiece is in a part of the circulating air flow pipeline, and the combustion device flo...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: in the airflow channel between the conveying track where the workpiece is placed and the burner, the airflow is mixed with a small amount of lipid combustibles, and there is a certain probability that the combustion device will circulate The combustible gas in the air flow pipeline ignites, causing an open flame in the pipeline, and the flame may spread along the pipeline to the circulating fan, causing damage or damage to the pipeline, circulating fan and other equipment components
