Heating machine structure capable of improving sealing stability

Abstract

The invention discloses a heating machine structure capable of improving the sealing stability. A material opening communicated with the inner portion of a shell is formed in the side wall of the shell. A thermal insulation sleeve is sleeved with the material opening. A through hole is formed in the thermal insulation sleeve. A sealing block is arranged on the shell and 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. Locking mechanisms are arranged on the shell and symmetrically arranged on the two sides of the thermal insulation sleeve. Each locking mechanism comprises a fixed block and a locking pin, wherein the locking pin penetrates through the fixed block. An isolation block is fixed to the sealing block. Connecting plates are symmetrically arranged on the side walls of the isolation block respectively. Hinge pins are arranged on the connecting plate. One end of each hinge pin is arranged inside the isolation block after penetrating through the corresponding connecting plate. The top ends of the connecting plates cave inwards to form through grooves communicated with the symmetrical side walls of the isolation block. One end of each locking pin is arranged inside the corresponding through groove. The mechanical locking structure is adopted for the heating machine structure, and therefore fixed sealing can be kept under the condition that internal pressure changes, and sealing performance is improved.

Description

technical field [0001] The invention relates to a structure, in particular to a heating machine structure capable of increasing sealing stability, 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 temperat...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem of seal failure due to changes in the air pressure of the existing heater after heating, and to design a heater structure that can increase the stability of the seal. The heater structure utilizes a mechanically locked structure. It can keep the seal fixed under changing conditions, improve the sealing performance, and solve the problem that the air pressure of the existing heating machine changes after heating and the seal fails.
