Problems solved by technology

[0005]Most of the current metallurgical manufacturers use continuous heat treatment furnaces to process metal workpieces. However, when using continuous heat treatment furnaces to heat treat metal workpieces, the furnace door in the heat treatment furnace It needs to be opened frequently, resulting in convective heat exchange between the air inside and outside the heat treatment furnace, which causes a large heat loss in the heat treatment furnace and increases unnecessary energy consumption costs. This situation is especially obvious for heat treatment furnaces that operate continuously
Moreover, when metal workpieces enter and exit the heat treatment furnace, all furnace doors in the heat treatment furnace must be opened at the same time, resulting in more serious convective heat transfer between the air inside and outside the heat treatment furnace, and greater heat loss. At the same time, high temperature, toxic and harmful substances in the heat treatment furnace are easily With the air convection heat transfer, it spreads to the workplace outside the heat treatment furnace, which seriously affects the working environment in the workplace and endangers the health of operators.
And the environmental pollution outside the workplace is also very serious

Embodiment 1

[0033] A kind of insulation furnace door system of the present embodiment, such as figure 1 As shown, there are four furnace doors 2 installed sequentially in the heat treatment furnace. When the heat preservation furnace door system is running, at least one of the two adjacent furnace doors 2 is closed.

[0034] Such as figure 2 with image 3 As shown, each furnace door 2 is provided with a rotating shaft 4 and a bearing 3, the upper end of each furnace door 2 is assembled and fixed with the rotating shaft 4, and the bearing 3 is installed on the top of the furnace body, and the furnace door 2 can be rotated through the rotating shaft 4 and the bearing 3 Rotating assembly connection and rotatable connection with the furnace body, at the same time, the distance between two adjacent furnace doors 2 is greater than or equal to the height of the furnace doors 2, so that the furnace doors 2 can be fully opened. When the metal workpiece enters the furnace and moves forward, push...

Embodiment 2

[0039]The main technical solutions of a heat-retaining furnace door system in this embodiment are basically the same as those in Embodiment 1. The features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the furnace door 2 is an automatic door that is automatically opened or closed by induction. The automatic door refers to recognizing the action of the metal workpiece approaching the furnace door 2 as a door opening signal, and opening the furnace door 2 through the drive system, and automatically closing the furnace door 2 after the metal workpiece leaves. A system for process control. The structure and principle of the automatic door all belong to the prior art, and are not described in detail here. The furnace door 2 of this embodiment is provided with a sensor for detecting the position of the metal workpiece. The sensor can be a position sensor, an infrared sen...

Embodiment 3

[0041] The main technical solutions of a heat-retaining furnace door system in this embodiment are basically the same as those in Embodiment 1. The features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the furnace door 2 is connected to the furnace body through a hinge.

Abstract

The invention discloses a thermal insulation furnace door system and a thermal treatment furnace with the same. The thermal insulation furnace door system comprises more than two furnace doors which are sequentially arranged. When the thermal insulation furnace door system runs, at least one of the two adjacent furnace doors is in a closed state. The thermal insulation furnace door system is applied to the thermal treatment furnace disclosed by the invention. Because the at least one of the two adjacent furnace doors is in the closed state, the convection is not formed between two adjacent cavities in the furnace and between the inside and the outside of the furnace, the energy loss of a metal workpiece during thermal treatment is reduced, and the diffusion of toxic and harmful substances in the thermal treatment furnace to the outside of the furnace is effectively reduced. Compared with the prior art, the thermal insulation furnace door system has the advantages of simple structure, low energy consumption, low pollution and the like.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a heat preservation furnace door system and a heat treatment furnace with the heat preservation furnace door system. Background technique [0002] Heat treatment furnace is a general term for industrial furnaces for heat treatment of metal workpieces. With the maturity of heat treatment technology and the complexity of heat treatment technology requirements, there are more and more types of heat treatment furnaces. The current heat treatment furnaces mainly include bell furnaces, roller furnaces Bottom furnace, chain furnace, traction heat treatment furnace, horizontal heat treatment furnace and other structural forms. in: [0003] The structure of the bell heat treatment furnace is composed of an outer cover, an inner cover and a hearth, etc. It is mainly used for the return treatment of metal workpieces, and is generally a discontinuous heat treatment furnace....
