Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pipe production technology, and more specifically, to a heating device for thermal insulation pipe production. Background Technology

[0002] Thermal insulation pipe is short for heat-insulated pipeline, used for transporting liquids, gases, and other media. It is widely used in thermal insulation projects for pipelines in petroleum, chemical, aerospace, district heating, central air conditioning, and municipal engineering. The main types of thermal insulation pipes include steel-jacketed steel composite type and polyurethane type.

[0003] A search revealed a novel heating device for producing insulated pipes, with publication number CN217196358U. This device includes a base, a working box, inlets and outlets, electric heating tubes, a working fan, a storage silo, a control discharge rack structure, a rotating flow hopper structure, a support plate, a conveyor belt, a rotating drum, pulleys, a belt, and a support motor and reducer. The working box is bolted to the middle of the upper part of the base. Electric heating tubes, inserted into the lower left and right sides of the working box and through the inlets and outlets located in the middle of the left and right sides, are bolted to the perimeter of the working box. A working fan is distributed on the outside of the electric heating tubes and is embedded in the rear of the working box. By controlling the discharge rack structure, the amount of material falling during left and right movement is controlled, preventing material accumulation from affecting the heating effect.

[0004] For common heating chambers used in the production of thermal insulation pipes, the chamber is mostly an integrated structure. After long-term heating treatment, the pungent odor inside the chamber is inconvenient to clean and remove. The accumulation of odor will affect the comfort of the working environment. Therefore, we have proposed a heating device for the production of thermal insulation pipes to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a heating device for the production of thermal insulation pipes. After the heating treatment is completed, the side plate of the shaft frame relative to the chassis is rotated, and both sides of the chassis are in an open state. The baffle is pulled horizontally outward relative to the sealing frame, and the exhaust port is connected to the exhaust fan. Then the exhaust fan is turned on, and the irritating odor accumulated inside the chassis enters the air purifier through the suction pipe under the action of negative pressure, effectively cleaning the exhaust gas.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

After the heating process is complete, the side panels are rotated relative to the chassis's frame, leaving both sides of the chassis open. The baffle is then pulled horizontally outward relative to the sealing frame, aligning the exhaust port with the exhaust fan. The exhaust fan is then activated, and the pungent odor accumulated inside the chassis is forced into the air purifier through the intake pipe under negative pressure, effectively cleaning the exhaust gas.
