DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figures 1 to 4As shown, an embodiment of the present application provides an industrial furnace with rapid cooling, including a furnace body 1, and also including a thermal insulation layer 2, an air cavity 3 is arranged between the thermal insulation layer 2 and the furnace body 1, an exhaust pump 4 and a vent 5 are penetrated through the thermal insulation layer 2, the exhaust pump 4 and the vent 5 are both connected to the air cavity 3, a sealing cover 51 is arranged on the vent 5, and a water cooling component is arranged on the furnace body 1.

[0018] Specifically, an electromagnetic valve is provided on the air inlet of the vacuum pump 4, so that the airtight effect of the vacuum pump 4 is good, and the thermal insulation layer 2 is made of thermal insulation material.

[0019] During operation, when the furnace body 1 needs to be heated, the sealing cover 51 closes the vent 5, and the vacuum pump 4 exhausts the air in the air cavity 3, making the air cavity 3 a vacuum cavity. When the furnace body 1 needs to be cooled after use, the vent 5 and the vacuum pump 4 are opened to allow the air in the air cavity 3 to circulate with the outside.

[0020] The above structure is arranged by arranging a heat-insulating layer 2, so that the heat in the furnace body 1 is not easily dispersed to the outside. By arranging an air cavity 3 between the heat-insulating layer 2 and the furnace body 1, and arranging an exhaust pump 4 connected with the air cavity 3, the air in the air cavity 3 is evacuated to form a vacuum cavity before the furnace body 1 is heated. The good heat-insulating effect of the vacuum is utilized to further reduce the heat loss. When the furnace body 1 needs to dissipate heat, the exhaust pump 4 and the vent 5 connected with the air cavity 3 can be utilized to allow the air in the air cavity 3 to circulate quickly. The air in the air cavity 3 is in contact with the furnace body 1. When the air in the air cavity 3 flows, the heat of the furnace body 1 can be transferred to the outside. At the same time, a water cooling component is also provided on the furnace body 1, so that the furnace body 1 can be cooled quickly and the working efficiency is high.

[0021] In this embodiment, the water cooling component includes a water cooling pipe, a spiral groove 12 is provided between the inner wall and the outer wall of the furnace body 1, the water cooling pipe is located in the spiral groove 12, and a water inlet and a water outlet are provided on the furnace body 1. The water cooling pipe includes a water inlet pipe 13 and a water outlet pipe 14 connected to the water inlet pipe 13, and the water inlet pipe 13 and the water outlet pipe 14 extend out of the furnace body 1 through the water inlet and the water outlet respectively. The water inlet pipe 13 is connected to the cold water tank through a water pump, and the water outlet pipe 14 is connected to a water storage tank 141, and a drain is provided on the water storage tank 141.

[0022] Specifically, the spiral groove 12 is configured to be spirally extended along the axial direction of the furnace body 1 , and the water cooling pipe is configured to be in close contact with the spiral groove 12 .

[0023] During operation, when the furnace body 1 needs to be cooled, the water in the cold water tank flows into the water cooling pipe through the water inlet pipe 13. The water cooling pipe is arranged on the spiral groove 12, that is, the cold water is spirally transmitted along the trajectory of the spiral groove 12 to the water outlet pipe 14, and then enters the water storage tank 141.

[0024] The above structure is arranged by setting a spiral groove 12 between the inner wall and the outer wall of the furnace body 1, and setting a water cooling pipe in the spiral groove 12, so that when the cold water flows along the water cooling pipe, the heat of the furnace body 1 can be transferred to the water. The spiral groove 12 is arranged between the inner wall and the outer wall of the furnace body 1, which better protects the water cooling pipe and prolongs the service life of the water cooling pipe. The spiral groove 12 is arranged so that the cold water can more fully contact with the furnace body 1 after the spiral movement, so that the furnace body 1 can be cooled faster. A water storage tank 141 is arranged, and a drain outlet is arranged on the water storage tank 141, so that the heat of the furnace body 1 can be used after heating the cold water.

[0025] In this embodiment, an exhaust duct 15 is provided on the furnace body 1 , and an exhaust fan 16 is fixedly connected to the furnace body 1 .

[0026] Specifically, a solenoid valve may be provided on the exhaust duct 15 , and an air outlet of the exhaust fan 16 may be provided to correspond to the exhaust duct 15 .

[0027] During operation, when the furnace body 1 needs to be cooled, the furnace mouth of the furnace body 1 is opened, the solenoid valve and the exhaust fan 16 are turned on, and the hot air inside the furnace body 1 is discharged to the outside through the exhaust duct 15, so that the temperature drops faster.

[0028] In this embodiment, a connecting ring 52 is provided on the vent 5, a first thread is provided on the outer wall of the connecting ring 52, a second thread is provided on the inner wall of the sealing cover 51, the first thread is threadedly connected to the second thread, and a sealing ring 521 is fixedly connected to one end of the connecting ring 52 away from the vent 5.

[0029] The above structure is arranged by providing a connecting ring 52 on the vent 5 and threading the sealing cover 51 and the connecting ring 52, so that the opening and closing of the vent 5 are relatively convenient, and a sealing ring 521 fixedly connected to the connecting ring 52 is provided. When the sealing cover 51 and the connecting ring 52 are threadedly connected, the sealing ring 521 closes the gap between the sealing cover 51 and the connecting ring 52, so that the sealing cover 51 has good airtightness.

[0030] In this embodiment, the thermal insulation layer 2 is an aluminum carbonate fiberboard.

[0031] The above structure is set up, and the insulation layer 2 is made of aluminum carbonate fiberboard, so that the insulation layer 2 has better insulation and heat resistance effects.
