[0034] In this embodiment: by using the first heat insulation board 201 and the second heat insulation board 202, the alumina fiberboard can withstand extremely high temperatures and is usually used as a lining material for high-temperature furnaces. It can effectively protect the furnace body from high temperature damage. The alumina fiberboard has low thermal conductivity, which helps to maintain the temperature in the furnace stable and improve thermal efficiency. Using the alumina fiberboard in a box furnace can significantly reduce energy consumption and improve work efficiency.

[0035] Aluminum silicate fiberboard can withstand high temperature environment and has a low thermal expansion coefficient, which means that the volume changes little when the temperature changes, which is conducive to maintaining the uniformity of the temperature in the furnace. Aluminum silicate fiberboard has good chemical stability and can resist the erosion of most chemical substances. It is suitable for a variety of harsh working environments. Using aluminum silicate fiberboard in box furnaces can improve the durability and safety of the furnace body;

[0036] The alumina fiberboard and the aluminum silicate fiberboard are clamped in the installation groove 203 and closely fit the inner wall of the furnace body to form a heat insulation layer, which can effectively block the heat inside the furnace body from transferring to the outside and significantly reduce the temperature of the outer wall of the furnace body.

[0037] As a preferred embodiment, a clamping block 204 is fixedly mounted on one side surface of the first heat insulation board 201, and a hole 205 is opened on the surface of the second heat insulation board 202, and the clamping block 204 and the hole 205 are connected by a snap-fit ​​connection.

[0038] In this embodiment, the first heat insulation board 201 and the second heat insulation board 202 are conveniently connected by the engagement of the block 204 with the hole 205 .

[0039] As a preferred embodiment, the cooling mechanism 4 includes a water tank 401, and the water tank 401 is arranged at the bottom of the box-type furnace body 1, a water pump 402 is fixedly installed inside the water tank 401, and a first connecting pipe 403 is fixedly installed on one side surface of the water pump 402, and a second connecting pipe 404 is fixedly installed on the other side surface of the water pump 402, the upper end of the second connecting pipe 404 is connected to a heat absorption pipe 405, and the other end of the heat absorption pipe 405 is connected to a drain pipe 406, and the other end of the drain pipe 406 extends to the interior of the water tank 401.

[0040] In this embodiment: by starting the water pump 402, the water pump 402 can pump out the water in the water tank 401 through the first connecting pipe 403, and discharge it into the heat absorption pipe 405 through the second connecting pipe 404, so as to absorb the temperature inside the furnace body, reduce the temperature inside the furnace and the temperature of the outer wall of the furnace body, reduce the risk of fire and explosion, improve the safety of operators, and reduce heat loss. Not only save energy, but also help reduce greenhouse gas emissions, which meets the requirements of sustainable development. The water that absorbs heat can be discharged into the water tank 401 through the drain pipe 406, so as to facilitate the recycling of water resources.

[0041] As a preferred embodiment, the heat absorbing tube 405 is arranged in a curved shape, and the heat absorbing tube 405 is made of a transparent glass tube.

[0042] In this embodiment: the heat absorption tube 405 is arranged in a curved shape and is made of a transparent glass tube, which can increase the contact area with the heat in the furnace body, better absorb the heat, and improve the efficiency of heat absorption.

[0043] As a preferred embodiment, a refrigerator 407 is fixedly installed inside the water tank 401 , and a water inlet pipe 408 is installed on one side surface of the refrigerator 407 , and the other side surface of the refrigerator 407 is fixedly connected to the first connecting pipe 403 .

[0044] In this embodiment: the water inside the water tank 401 will be heated up after a long period of heat absorption and circulation. By setting up a refrigerator 407, when the water is pumped away by the water pump 402, the heated water can be cooled by the refrigerator 407 to facilitate better absorption of heat by the water.

[0045] As a preferred embodiment, a slot 409 is provided on the inner wall surface of the back of the box-type furnace body 1 , and an air inlet 410 is provided on the surface of the slot 409 , and a fan 411 is engaged and connected inside the slot 409 .

[0046] In this embodiment, a fan 411 is installed on the back of the furnace body. When the fan 411 is working, it blows toward the heat absorbing tube 405, so as to better dissipate the internal heat and carry out heat dissipation so that the heat is quickly taken away.

[0047] The working principle is: by adopting the first insulation board 201 and the second insulation board 202, the first insulation board 201 and the second insulation board 202 are respectively made of alumina fiberboard and aluminum silicate fiberboard, which can effectively protect the furnace body from high temperature damage. The thermal conductivity of the alumina fiberboard is low, which helps to maintain the temperature inside the furnace stable and improve thermal efficiency. The use of alumina fiberboard in a box-type furnace can significantly reduce energy consumption, improve work efficiency, and help maintain the uniformity of the temperature inside the furnace. It is suitable for a variety of harsh working environments. The use of aluminum silicate fiberboard in a box-type furnace can improve the durability and safety of the furnace body, thereby effectively blocking the transfer of heat from the inside of the furnace body to the outside and significantly reducing the temperature of the outer wall of the furnace body.

[0048] When the furnace body is working, by starting the water pump 402, the water pump 402 can pump out the water inside the water tank 401 through the first connecting pipe 403, and discharge it into the heat absorption pipe 405 through the second connecting pipe 404, so as to absorb the temperature inside the furnace body. Lowering the temperature inside the furnace can reduce the risk of fire and explosion, improve the safety of operators, and reduce heat loss. It not only saves energy, but also helps to reduce greenhouse gas emissions, which meets the requirements of sustainable development. The water that absorbs heat can be discharged into the water tank 401 through the drain pipe 406, which is convenient for the recycling of water resources. In combination with the first insulation board 201 and the second insulation board 202, the temperature of the outer wall can be greatly reduced to avoid thermal pollution to the surrounding environment and even pose a direct safety threat to the surrounding staff. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0049] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
