[0002] Crucible furnace is the simplest smelting equipment, mainly used to melt non-ferrous metals with low melting points, such as copper, aluminum and their alloys.

[0003] Existing gas-fired crucible furnaces generate waste gas during use, which contains harmful substances and still has a certain amount of heat. If the waste gas is directly discharged, it will cause great harm to the environment. Therefore, a double regenerative gas-fired crucible furnace is proposed. Utility Model Content

[0004] In view of the above problems existing in the existing gas crucible furnace, the present utility model is proposed.

[0005] Therefore, the utility model aims to provide a double regenerative gas-fired crucible furnace, which solves the problem that the gas-fired crucible furnace cannot process the generated waste gas.

[0008] Preferably, the air inlet channel and the slag discharge channel are both inclined channels.

[0009] Preferably, a blocking cover is provided on the side wall of the furnace body and at the opening of the slag discharge channel.

[0010] Preferably, a lifting brick connected to the bottom of the furnace body is fixedly provided at the bottom of the crucible.

[0011] Preferably, the inner wall of the furnace body is provided with a heat-insulating layer.

[0012] Furthermore, the circulating dual heat storage channels are paved with heat storage ceramic blocks.

[0013] Preferably, support feet are fixedly provided at the four corners of the bottom of the furnace body.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. In the utility model, the waste gas generated in the combustion process is discharged into the interior of the circulating inlet and outlet channels through the circulating double heat storage channels and the circulating inlet and outlet channels, and then discharged along the circulating double heat storage channels and the circulating inlet and outlet channels. Since the circulating double heat storage channels are paved with heat storage ceramic blocks, the heat storage ceramic blocks can improve the combustion efficiency and reduce the generation of harmful substances in the waste gas, thereby achieving the purpose of environmental protection and energy saving.

[0016] 2. The utility model has a slag discharge channel, and a certain amount of waste slag will be generated during the heating and combustion process. The waste slag can be discharged to the outside of the furnace body through the slag discharge channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a double heat storage type gas-fired crucible furnace.

[0025] The utility model provides Figure 1-2A double regenerative gas crucible furnace shown comprises a furnace body 1 and a crucible 2. The crucible 2 is fixedly installed inside the furnace body 1. A lifting brick 9 connected to the bottom of the furnace body 1 is fixedly provided at the bottom of the crucible 2, so that the bottom of the crucible 2 can be elevated and installed. An air inlet channel 3 is provided on one side of the interior of the furnace body, and a slag discharge channel 4 is provided on the other side of the interior of the furnace body 1. Both the air inlet channel 3 and the slag discharge channel 4 are inclined channels. A baffle 8 is provided on the side wall of the furnace body 1 and at the opening of the slag discharge channel 4. The air inlet channel 3 can ensure the entry of gas, and then the bottom of the crucible 2 can be heated. A certain amount of waste slag will be generated during the heating and combustion process, and the waste slag can be discharged to the outside of the furnace body 1 through the slag discharge channel 4; an insulation layer 10 is provided on the inner side wall of the furnace body 1, which can reduce the heat loss inside the furnace body 1 and improve the heating efficiency; supporting feet 11 are fixedly provided at the four corners of the bottom of the furnace body 1, and the supporting feet 11 can firmly support the bottom of the furnace body 1.

[0026] Among them, Figure 2-3 A circulating inlet and outlet channel 5 extending upward is provided on one side of the furnace body 1 and above the air inlet channel 3, and a circulating double heat storage channel 6 is provided at the upper end of the circulating inlet and outlet channel 5. The circulating double heat storage channel 6 is paved with heat storage ceramic blocks, and a circulating inlet and outlet air port 7 is provided at the upper end of the circulating double heat storage channel 6. The waste gas generated during the combustion process will be discharged into the circulating inlet and outlet channel 5, and then discharged along the circulating double heat storage channel 6 and the circulating inlet and outlet air port 7. Since the circulating double heat storage channel 6 is paved with heat storage ceramic blocks, the heat storage ceramic blocks can improve the combustion efficiency and reduce the generation of harmful substances in the exhaust gas, thereby achieving the purpose of environmental protection and energy saving.

[0027] When in use, the air inlet channel 3 can ensure the entry of fuel gas, and the bottom of the crucible 2 can be heated to melt the inside of the crucible 2. The waste gas generated during the combustion process will be discharged into the interior of the circulating inlet and outlet channel 5, and then discharged along the circulating double heat storage channel 6 and the circulating inlet and outlet air port 7. Since the circulating double heat storage channel 6 is paved with heat storage ceramic blocks, the heat storage ceramic blocks can improve the combustion efficiency and reduce the generation of harmful substances in the exhaust gas, thereby achieving the purpose of environmental protection and energy saving. A certain amount of waste slag will be generated in the process of heating and combustion, and the waste slag can be discharged to the outside of the furnace body 1 through the slag discharge channel 4.
