Thermal insulation furnace with temperature insulation function

Abstract

This utility model relates to the field of heat preservation furnace technology, specifically a heat preservation furnace with heat insulation function. It includes a heat preservation furnace body, with a sealing cover plate installed on one side surface. The heat preservation furnace body has an inner shell and an outer shell. The inner shell has a first vacuum insulation layer, and the outer shell has a second vacuum insulation layer. A ceramic fiber layer is installed between the inner shell and the outer shell, and a heat insulation component is installed inside the ceramic fiber layer. In this improved heat preservation furnace, nitrogen stored in a gas tank is sequentially delivered to each gas bladder through a first and second gas pipe using a gas pump, filling the gas bladders with nitrogen.

Furthermore, the first vacuum insulation layer of the inner shell and the second vacuum insulation layer of the outer shell provide heat insulation, preventing heat loss.

Description

Technical Field

[0001] This utility model relates to the field of heat preservation furnace technology, specifically a heat preservation furnace with heat insulation function. Background Technology

[0002] Metal casting is typically produced from metallic materials such as iron, aluminum, copper, and zinc through processes including melting, pouring into a mold, and cooling and solidification. Metal castings have wide applications in industrial production and occupy an important position in the manufacturing industry. In metal casting, the holding furnace serves to transfer and preserve the molten metal.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: the existing heat preservation furnaces usually adopt a simpler structure and use simpler heat insulation materials, such as asbestos and other common heat insulation materials. Although they can play a certain heat preservation role, they are easy to lose their heat insulation properties after long-term use, resulting in poor thermal stability of the heat preservation furnace and inability to effectively reduce heat loss. Utility Model Content

[0004] The purpose of this utility model is to provide a heat-insulating furnace with heat insulation function to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a heat-insulating furnace with heat insulation function, comprising a furnace body, a sealing cover plate installed on one side surface of the furnace body, an inner shell and an outer shell inside the furnace body, a first vacuum insulation layer inside the inner shell, a second vacuum insulation layer inside the outer shell, a ceramic fiber layer installed between the inner shell and the outer shell, and a heat insulation component inside the ceramic fiber layer.

[0005] The heat insulation component includes a support plate installed on one side surface of the heat preservation furnace body. An air tank is installed on the top surface of the support plate, an air pump is installed on the top surface of the air tank, one end of a first air pipe is installed on one side surface of the air pump, and an air bag is installed on the other end of the first air pipe. The air bags are connected to each other through a second air pipe.

[0006] More preferably, the ceramic fiber layer is shaped as a mesh framework.

[0007] More preferably, the ceramic fiber layer is arranged in a surrounding manner with respect to the thermal insulation component.

[0008] More preferably, there are four airbags in total, and the airbags are symmetrically distributed about the central axis of the heat preservation furnace body.

[0009] More preferably, the gas tank is configured as a pneumatic mechanism by means of an air pump, a first air pipe, a second air pipe and an air bag.

[0010] More preferably, a sealing ring is provided at the connection between the sealing cover and the furnace body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This heat-insulating furnace uses an air pump to sequentially deliver nitrogen stored in a gas tank to each gas bladder through a first and second gas pipe, filling the gas bladders with nitrogen. The low thermal conductivity of nitrogen helps improve the heat insulation effect of the furnace body and reduces heat conduction. Furthermore, the first vacuum insulation layer of the inner shell and the second vacuum insulation layer of the outer shell can perform heat insulation functions to prevent heat loss.
