Heating machine structure capable of improving thermal insulation effect

Abstract

The invention discloses a heating machine structure capable of improving the thermal insulation effect. A material opening communicated with the inner portion of a shell is formed in the side wall of a shell. A thermal insulation sleeve is sleeved with the material opening. The outer wall of the thermal insulation sleeve is simultaneously attached to the side wall of the shell and the inner wall of the material opening. A vent hole is formed inside the thermal insulation sleeve. The bottom face, provided with the small area, of a trapezoid body is arranged inside the material opening, and the bottom face, provided with the large area, of the trapezoid body is arranged outside the shell. A sealing block is arranged on the side wall, provided with the material port, of the shell, and is connected with a rotating handle. The end, away from the sealing block, of the rotating handle is connected with the side wall, provided with the material opening, of the shell. The rotating handle can rotate around an end of the rotating handle. The sealing block is of a trapezoid body structure matched with the through hole. The side wall of the sealing block makes seamless contact with the side wall of the through hole. The heating machine tightly seals the material opening through the rotatable structure and the trapezoid body mechanism with the inclined side walls, and therefore heat is sealed in the shell and can not be dissipated, heat is saved, and safety of operators is ensured.

Description

technical field [0001] The invention relates to a structure, in particular to a heating machine structure capable of improving heat preservation effect, and belongs to the field of machinery. Background technique [0002] Heating is the process by which a heat source transfers thermal energy to a cooler object to make it hotter. According to the heat energy obtained, it can be divided into two types: direct and indirect. Direct heat source heating is to directly add heat energy to materials, such as flue gas heating, electric current heating and solar radiation heating. Indirect heat source heating is to add the heat energy of the above-mentioned direct heat source to an intermediate heat carrier, and then the intermediate heat carrier transfers the heat energy to the material, such as steam heating, hot water heating, mineral oil heating, etc. In the metallurgical industry, heating furnaces customarily refer to industrial furnaces that heat metals to rolling to forging te...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the unreasonable sealing in the existing metal heaters, which causes the heat to radiate and cause potential safety hazards, and designs a heater structure that can improve the heat preservation effect. The heater utilizes a rotatable structure and a tilting The trapezoidal mechanism on the side wall tightly seals the material opening, so that the heat is sealed in the shell, which solves the problem of unreasonable sealing in the existing metal heaters, which makes the heat radiate and poses a safety hazard.
