Problems solved by technology

[0003] When the existing box-type furnace is performing heat treatment on the workpiece, it is easy to cause oxidation of the workpiece during heating, thereby affecting the quality of the workpiece. Not only that, but when the existing box-type furnace is working, because the position of the workpiece is fixed , resulting in uneven heating of the workpiece, which affects the heat treatment work and reduces the reliability of the existing box furnace

Abstract

The invention relates to a uniformly heated box type furnace which comprises a main body, a door body and two heating devices, and further comprises an air-entrapping mechanism and a circulating mechanism, wherein the air-entrapping mechanism comprises a material storage box, an air-entrapping assembly and two connecting assemblies, the air-entrapping assembly comprises an air-entrapping box, a driving unit, a driving plate and a connecting pipe, and the driving unit comprises a motor, a rotating rod and a connecting rod; the connecting assembly comprises a connecting box, an air inlet pipe and an air outlet pipe; the circulating mechanism comprises an air cylinder, two power assemblies and two circulating assemblies; each power assembly comprises a piston, a spring and a connecting rope,and each circulating assembly comprises a circulating pipe, a first branch pipe and a second branch pipe. The uniformly heated box type furnace achieves the function of adding an atmosphere into the main body and avoids a phenomenon that a workpiece subjected to thermal treatment is oxidized, so that the quality of workpiece thermal treatment is improved, and the reliability of the equipment is improved. Through a circulating mechanism, a function of circularly flowing hot air is achieved, so that the workpiece is heated uniformly, and the heating effect is improved.

Description

technical field [0001] The invention relates to the field of heat treatment, in particular to a uniformly heated box furnace. Background technique [0002] Box furnace, also known as muffle furnace, is easy to operate, easy to maintain, and equipped with a controllable chimney behind the furnace. It is suitable for chemical analysis of coal, coking products and chemical raw materials. It can be used in industries and departments such as electric power, coal, papermaking, petrochemical, cement, agriculture and animal husbandry, medical research, teaching, etc. [0003] When the existing box-type furnace is performing heat treatment on the workpiece, it is easy to cause oxidation of the workpiece during heating, thereby affecting the quality of the workpiece. Not only that, but when the existing box-type furnace is working, because the position of the workpiece is fixed , causing the workpiece to be heated unevenly, thereby affecting the heat treatment work and reducing the ...
