Description

Technical Field

[0001] This application relates to the field of metal heat treatment technology, and in particular to a constant temperature device for heat treatment of non-ferrous metals. Background Technology

[0002] Non-ferrous metals refer to metals other than iron, manganese, and chromium, mainly including aluminum, copper, and lead. They have important applications in various fields such as industry, electronics, and energy. Heat treatment of non-ferrous metals is a process that alters the structure and properties of non-ferrous metals and their alloys by heating and cooling them. The purpose of heat treatment is to improve the hardness, strength, plasticity, toughness, and corrosion resistance of the metal to meet different application requirements.

[0003] Traditional constant temperature devices for heat treatment of non-ferrous metals are not convenient for quickly cooling the non-ferrous metals after heat treatment. Waiting for cooling takes a long time, resulting in low processing efficiency. Moreover, heat loss occurs during the heat treatment process, increasing energy consumption. Utility Model Content

[0004] This application provides a constant temperature device for heat treatment of non-ferrous metals to solve the problems of inconvenience in rapidly cooling non-ferrous metals after heat treatment and heat loss during the heat treatment process.

[0005] This application provides a constant temperature device for heat treatment of non-ferrous metals, including a heat treatment inner liner. Cavities are formed on both sides of the inner wall of the heat treatment inner liner. A heating plate is fixedly installed inside each cavity. A cooling jacket is fixedly installed on the outer surface of the heat treatment inner liner. A cooling copper pipe is fixedly installed inside the cooling jacket. A conveying pipe is connected to one end of the cooling copper pipe, and a water pump is connected to one end of the conveying pipe. A coolant tank is fixedly installed on one side of the water pump. A heat-conducting plate is fixedly installed on one side of the coolant tank. A thermoelectric cooling element is fixedly installed on one side of the heat-conducting plate. An auxiliary heating plate is fixedly installed on the bottom surface of the heat treatment inner liner. An auxiliary hot water pipe is fixedly installed inside the auxiliary heating plate, and a heat exchanger is connected to one end of the auxiliary hot water pipe.

[0006] Preferably, a rock wool layer is fixedly disposed on the surface of the cooling interlayer, and a ceramic fiber layer is fixedly disposed on the outer surface of the rock wool layer. The rock wool layer and the ceramic fiber layer are used to reduce heat loss and play a role in heat preservation.

[0007] Preferably, the water pump's input pipe is provided with a liquid extraction pipe, which is installed inside the coolant tank to facilitate the extraction of coolant from the tank.

[0008] Preferably, a return pipe is provided through the top surface of the coolant tank, and one end of the return pipe is connected through the cooling copper pipe, so that the coolant can flow back into the coolant tank.

[0009] Preferably, the top surface of the heat treatment inner liner is fitted with a lid, the top surface of the lid is connected to a hot air pipe, one end of the hot air pipe is connected to the input pipe of the heat exchanger, and the heat exchanger is convenient for heat exchange with hot air.

[0010] Preferably, a cooling fan is fixedly installed on one side of the thermoelectric cooling chip. The cooling fan is used to accelerate the heat dissipation of the thermoelectric cooling chip and facilitates the heat dissipation of the thermoelectric cooling chip.

[0011] Preferably, a temperature controller is electrically connected to one side of the heating plate. The temperature controller is fixedly installed on the surface of the ceramic fiber layer and is used to control the heating temperature of the heating plate.

[0012] Beneficial effects:

[0013] Considering the difficulty in rapidly cooling non-ferrous metals after heat treatment and the potential for heat loss during the process, an electric heating plate heats the non-ferrous metals inside the heat treatment liner. Rock wool and ceramic fiber layers reduce heat loss, and hot air pipes transport the hot air generated during heat treatment to a heat exchanger for heat exchange. The heat is then transferred to the auxiliary hot water pipes to provide auxiliary heating for the heat treatment liner, thus reducing heat loss. The heat can be recovered for auxiliary heating, saving energy.

[0014] After heat treatment, the water pump is turned on to extract the coolant from the coolant tank and transport it to the cooling copper pipe through the delivery pipe. This absorbs the heat inside the heat treatment tank, allowing the non-ferrous metal to cool down and solidify quickly. The thermoelectric cooling element rapidly cools the coolant in the coolant tank, facilitating its recycling and improving the efficiency of the heat treatment operation.
