Description

Technical Field

[0001] The utility model relates to the technical field of gas heating furnaces, in particular to a heat storage type gas heating furnace. Background Art

[0002] There are two main types of regenerative heating furnaces currently in use. One is a built-in type, that is, the regenerative chamber is located at the lower part of the furnace wall and is filled with small regenerative balls, which makes the foundation of the heating furnace deeper and inconvenient to build and maintain; the other is an external type, that is, the regenerative chamber is symmetrically arranged on the outside of the furnace body.

[0003] However, no matter which form of heating furnace is used, the heated products in the heating furnace are taken in and out only by opening a sealed door on one side, so that after the products in the heating furnace are heated, the heated products need to be taken out before another heated product can be put into the heating furnace, resulting in a long heating interval between the two products. The protective door of the heating furnace is opened for a long time, causing a large amount of internal heat loss, and also affecting the working efficiency of the heating furnace. Secondly, when the existing heating furnace heats the products placed inside, it only heats the inside through gas, resulting in a long temperature time in the heating furnace and causing a waste of gas. In view of the above problems, the inventor proposes a heat storage gas heating furnace to solve the above problems. Utility Model Content

[0004] In order to solve the problem that the existing heating furnace, when in use, only a sealed door is opened on one side to take and put the heated products in the heating furnace, so that after the heating of the products in the heating furnace is completed, the heated product needs to be taken out before another heated product can be put into the heating furnace, resulting in a long heating interval between the two products, and the protective door of the heating furnace is opened for a long time, causing a large amount of internal heat loss, and also affecting the working efficiency of the heating furnace; the purpose of the utility model is to provide a heat storage gas heating furnace.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a regenerative gas heating furnace, comprising a fixed platform, a heating furnace body is fixedly installed in the middle of the top surface of the fixed platform, electric lifting doors are installed in both sides of the heating furnace body, a conveying device is installed in the top surface of the fixed platform, the conveying device comprises a motor, the motor is fixedly installed in the middle of one side of the fixed platform, a screw rod is fixedly installed at the output end of the motor, a first sliding sleeve and a second sliding sleeve are respectively threadedly sleeved on the surface of the screw rod, a first conveying platform is fixedly installed on the top surface of the first sliding sleeve, a second conveying platform is fixedly installed on the top surface of the second sliding sleeve, and the first conveying platform and the second conveying platform cooperate with each other;

[0006] When the heated product needs to be transported into the heating furnace body for transportation, the product is placed on the top surface of the first conveyor platform, the switch of the motor is turned on, and the screw rod is controlled to rotate through the output end of the motor. When the screw rod rotates, the first sleeve and the second sleeve are controlled to move, and the product on the first conveyor platform is transported into the heating furnace body through the first sleeve. After the transportation is completed, the second sleeve moves the second conveyor platform to the left side of the heating furnace body. When the product on the top surface of the first conveyor platform is heated in the heating furnace body, the next product to be heated is placed on the second conveyor platform moved out from the left side of the heating furnace body. After the product on the first conveyor platform is heated, the screw rod is reversed by the motor to transport the product on the second conveyor platform into the heating furnace body, and the product heated on the first conveyor platform is moved out, and so on.

With the assistance of the auxiliary heating device, the temperature rise efficiency in the heating furnace body is improved, the preheating time of the heating furnace body is shortened, and the use of gas is reduced.
