Anti-explosion spinning preheating furnace

Abstract

The invention provides an anti-explosion spinning preheating furnace. The anti-explosion spinning preheating furnace is structurally characterized in that an insulating layer is arranged on an inner wall of a furnace body, a heating cavity is formed in the furnace body, a spinning tube and a heat conducting oil tube which are arranged inside and outside concentrically penetrate through the heatingcavity, the heat conducting oil tube is externally connected with a heat conducting oil heating device, the heat conducting oil tube in the heating cavity is provided with an expansion section, the heat conducting oil tube outside the heating cavity is provided with a decompression tube, and a decompression valve is arranged on the decompression tube. The anti-explosion spinning preheating furnace has the advantages that heat conducting oil is heated by the heat conducting oil heating device and then is used for heating the spinning tube through the heat conducting oil tube, during heating, pressure can be alleviated through the expansion section, and anti-explosion performance of the furnace is improved; when the pressure continuously increases, the decompression valve can be turned on,so that air in the heat conducting oil tube can be exhausted through the decompression tube, the pressure is released, and the anti-explosion performance of the furnace is improved furtherly; througha temperature sensor and a temperature display, a preheating temperature can be monitored in real time, when the temperature is too high or too low, the heat conducting oil heating device can be controlled to rise the temperature, operational stability of the furnace is improved furtherly, and the anti-explosion performance of the furnace is guaranteed.

Description

technical field [0001] The invention relates to an explosion-proof spinning preheating furnace. Background technique [0002] The spinning unit is an important equipment for chemical fiber production, mainly used for melt spinning. When in use, the spinning unit needs to be preheated to ensure the use effect when the chips are melted. [0003] In the prior art, the spinning preheating furnace is generally used to preheat the spinning, and a plurality of heat conducting oil pipes with heat conducting oil are arranged in the preheating furnace, and the spinning is preheated by the heat conducting oil when passing through the preheating furnace. However, after a long period of use of the preheating furnace, the pressure in the heat transfer tube is relatively large, which is prone to bursting, damage to equipment, and safety production accidents. Although there is also an explosion-proof spinning preheating furnace in the prior art, the structure is simple and the use effect i...

Problems solved by technology

However, after a long period of use in the preheating furnace, the pressure in the heat transfer tube is relatively large, which is prone to bursting, damage to equipment, and accidents in production safety.

Although there are explosion-proof spinning preheating furnaces in the prior art, they are simple in structure and generally effective in use, and still cannot meet the requirements of safe production.
