[0028] ReferenceFigure 1 And Figure 2 When the furnace body 1 needs to be cooled, the high-pressure cold water source is connected to the water inlet end of the cooling water pipe 4, and because the first shunt pipe 41 and the second shunt pipe 44 are in communication with the cooling water pipe 4, when the high-pressure cold water enters the cooling water pipe 4, the first circular rod 42 in the first shunt pipe 41 and the second circular rod 45 in the second shunt pipe 44 are affected by the water pressure and move upward, and the first circular plate 43 fixedly connected to the first circular rod 42 and the second circular plate 46 fixedly connected to the second circular rod 45 move upward, so that the air exhaust pipe 2 and the air inlet pipe 3 are both in an open state.

[0029] The air exhaust pipe 2 is provided with an air cooling mechanism for cooling the furnace body 1, which comprises a rectangular box 5 arranged in the air exhaust pipe 2, the rectangular box 5 being fixedly connected to the cooling water pipe 4, a hollow rod 6 being rotatably connected in the rectangular box 5, a rotating plate 52 being fixedly connected to the hollow rod 6, the rotating plate 52 being rotatably connected in the rectangular box 5, a control rod 51 being axially slidably connected in the hollow rod 6, a blocking ring 53 being fixedly connected to one end of the control rod 51 close to the first circular plate 43, the blocking ring 53 intermittently abutting against the hollow rod 6, and the air cooling mechanism further comprising a blade 54, a plug rod 56 being fixedly connected to the blade 54, the plug rod 56 being rotatably connected to the hollow rod 6 and penetrating through the hollow rod 6 and being fixedly connected to a push rod 58, the control rod 51 being fixedly connected with a push rod 55 for pushing the push rod 58 to increase the turning angle of the blade 54, and a torsion spring 57 being sleeved between the blade 54 and the push rod 58 on the plug rod 56, two ends of the torsion spring 57 being fixedly connected to the blade 54 and the hollow rod 6 respectively.

[0030] Referring to Figure 2 And Figure 3 The cold water flows in the cooling water pipe 4 and is finally discharged from the discharge end of the cooling water pipe 4, and in the process of flowing, the cold water passes through the rectangular box 5, as shown in Figure 3 The connection between the cooling water pipe 4 and the rectangular box 5 is not located on the axis of the hollow rod 6 in the vertical direction, and when the high-pressure cold water enters the rectangular box 5 through the cooling water pipe 4, it will impact the rotating plate 52, causing the hollow rod 6 to rotate, and the blade 54 on the hollow rod 6 rotates to exhaust air to the direction of the furnace body 1, thereby generating negative pressure in the furnace body 1, and external air can enter the furnace body 1 through the air inlet pipe 3 to cool the furnace body 1.

[0031] One end of the control rod 51 away from the blocking ring 53 is fixedly connected with a bearing 72, a first electric telescopic rod 7 is fixedly connected to the air exhaust pipe 2, an output end of the first electric telescopic rod 7 is fixedly connected with a connecting plate 71, the control rod 51 is rotatably connected to the connecting plate 71 through the bearing 72, a temperature sensor 73 for controlling the first electric telescopic rod 7 is fixedly connected to the upper part of the air exhaust pipe 2 on the furnace body 1, and a probe of the temperature sensor 73 penetrates through the side wall of the furnace body 1 and extends into the interior thereof.

[0032] With reference to Figures 1-3 The temperature sensor 73 on the furnace body 1 detects the temperature of the furnace body 1, and when the temperature of the furnace body 1 gradually decreases, the temperature sensor 73 controls the first electric telescopic rod 7 to extend, and the connecting plate 71 fixedly connected to the output end of the first electric telescopic rod 7 is driven to move away from the air duct 2, and the control rod 51 connected to the connecting plate 71 through the bearing 72 is driven to move synchronously with the connecting plate 71, so that the push rod 55 on the control rod 51 pushes the shift rod 58, and since the shift rod 58 is fixedly connected to the plug rod 56, the plug rod 56 can be rotated, and the blade 54 fixedly connected to the plug rod 56 rotates synchronously, and the rotation angle of the blade 54 increases, so that the blade 54 can have a larger air volume when rotating, thereby enhancing the cooling effect of the furnace body 1, so that the furnace body 1 will not be damaged by thermal expansion and cold contraction due to sudden cooling at high temperature.

[0033] The air inlet pipe 3 is provided with an auxiliary mechanism for assisting the air cooling mechanism to effectively cool the furnace body 1, and the auxiliary mechanism includes a cooling nitrogen inlet pipe 12 connected to an external nitrogen source, the cooling nitrogen inlet pipe 12 is in communication with the air inlet pipe 3, and the second electric telescopic rod 32 is fixedly connected to the bottom of the air inlet pipe 3 on the furnace body 1, and the output end of the second electric telescopic rod 32 is fixedly connected to the first circular table block 33 for controlling the amount of cooling nitrogen introduced by the cooling nitrogen inlet pipe 12, and the air volume sensor 31 for controlling the second electric telescopic rod 32 is fixedly connected in the air inlet pipe 3.

[0034] With reference to Figure 3 And Figure 4 When the rotation angle of the blade 54 increases to increase the air volume, the air inlet amount of the air inlet pipe 3 into the furnace body 1 also increases, and since the rotation angle of the blade 54 gradually changes, the air inlet amount gradually increases, and the gradual increase of the air volume causes the air volume sensor 31 to control the second electric telescopic rod 32 to gradually contract, and the first circular table block 33 fixedly connected to the second electric telescopic rod 32 gradually moves away from the inlet end of the cooling nitrogen inlet pipe 12, and the amount of cooling nitrogen entering gradually increases, and the entering cooling nitrogen is affected by the negative pressure in the furnace body 1 to enter the furnace body 1 to enhance the cooling of the furnace body 1.

[0035] The air inlet pipe 3 is fixedly connected with a pressure tank 34 containing an oxide cleaning agent, the pressure tank 34 is fixedly connected with a discharge pipe 35, the air inlet pipe 3 is fixedly connected with a piston cylinder 38 containing air, the piston cylinder 38 is slidably connected with a piston rod 39, the piston rod 39 is provided with a spraying mechanism for controlling the spraying of the oxide cleaning agent in the pressure tank 34, the spraying mechanism comprises an extension pipe 36 fixedly connected to the discharge pipe 35, a first atomizing nozzle 37 fixedly connected to one end of the extension pipe 36 away from the discharge pipe 35, the piston rod 39 is slidably connected in the discharge pipe 35, and the outer wall of the piston rod 39 is in close contact with the inner wall of the discharge pipe 35, the piston rod 39 is used to control the communication state of the discharge pipe 35 and the extension pipe 36.

[0036] Referring to Figure 5 and Figure 6 When the cooling nitrogen gas is introduced, the piston cylinder 38 arranged at the lower end of the cooling nitrogen gas introduction pipe 12 is affected by the cooling nitrogen gas, so that the air in the piston cylinder 38 is cooled and the volume is reduced, and then the piston rod 39 slides into the piston cylinder 38, as shown in Figure 6 When the piston rod 39 slides into the piston cylinder 38, the discharge pipe 35 and the extension pipe 36 are in communication, and then the oxide cleaning agent in the pressure tank 34 can flow through the discharge pipe 35 and the extension pipe 36 and be sprayed from the first atomizing nozzle 37 into the furnace body 1, so that the oxide in the furnace body 1 is soaked with the cleaning agent, making it more convenient to clean the furnace body 1.

[0037] Example 2

[0038] The spraying mechanism is replaced on the basis of example one, the spraying mechanism comprises an L-shaped pipe 8 fixedly connected to the piston rod 39, one end of the L-shaped pipe 8 is fixedly connected with a second atomizing nozzle 84, the other end of the L-shaped pipe 8 is slidably connected in the discharge pipe 35, the L-shaped pipe 8 is fixedly connected with an extension rod 81, the extension rod 81 is fixedly connected with a second circular block 82, the discharge pipe 35 is fixedly connected with an annular plate 83, and the annular plate 83 intermittently abuts against the second circular block 82.

[0039] Referring to Figure 7 and Figure 8When the nitrogen gas in the cooling nitrogen inlet pipe 12 is introduced into the exhaust pipe 2, the air inside the piston cylinder 38 is cooled and contracted by the nitrogen gas, and the piston rod 39 contracts into the piston cylinder 38. At this time, the L-shaped tube 8 fixedly connected to the piston rod 39 moves synchronously away from the discharge pipe 35 with the piston rod 39. As a result, the second frustum block 82 on the L-shaped tube 8 moves away from the annular plate 83. At this time, the oxide cleaning agent in the pressure tank 34 can flow through the discharge pipe 35 and the L-shaped tube 8 and then be sprayed out from the second atomizing nozzle 84 into the furnace body 1, so that the oxides in the furnace body 1 are soaked in the cleaning agent, making it more convenient to clean the furnace body 1. The air introduced into the piston cylinder 38 should have a certain pressure, which can offset the pressure generated by the pressure tank 34.

[0040] The working principle of Embodiment 1 of the present invention: When the furnace body 1 needs to be cooled, the rapid cooling mechanism of the high-temperature metallurgical resistance furnace connects the high-pressure cold water source from the inlet end of the cooling water pipe 4. Since the first branch pipe 41 and the second branch pipe 44 are connected to the cooling water pipe 4, when the high-pressure cold water enters the cooling water pipe 4, the first round rod 42 in the first branch pipe 41 and the second round rod 45 in the second branch pipe 44 move upward under the influence of water pressure. As a result, the first round plate 43 fixedly connected to the first round rod 42 and the second round plate 46 fixedly connected to the second round rod 45 move upward, so that the exhaust pipe 2 and the air inlet pipe 3 are both in the open state.

[0041] When the furnace body 1 is in normal working condition, the cooling water pipe 4 is not flowing with water, so the first round rod 42 and the second round rod 45 do not move upward, and the first round plate 43 and the second round plate 46 have sufficient self-weight, so the exhaust pipe 2 and the air inlet pipe 3 are in a blocked state.

[0042] Cold water flows inside cooling water pipe 4 and eventually exits from the outlet of cooling water pipe 4. During the flow of cold water, it passes through rectangular box 5, such as... Figure 3 As shown, the connection between the cooling water pipe 4 and the rectangular box 5 is not located on the axis of the hollow rod 6 in the vertical direction. Therefore, when the high-pressure cold water enters the rectangular box 5 through the cooling water pipe 4, it will impact the rotating plate 52, causing the hollow rod 6 to rotate. Consequently, the blades 54 on the hollow rod 6 rotate and draw air towards the furnace body 1, thereby generating negative pressure inside the furnace body 1. As a result, external air can enter the furnace body 1 through the air inlet pipe 3 to cool the furnace body 1.

[0043] The cooling water pipe 4 is a rigid pipe, which can ensure the stability of the connection with the rectangular box 5 so that the rectangular box 5 will not shake. During the manufacturing process, the angle of the blade 54 is adjusted so that when the blade 54 is driven to rotate by the hollow rod 6, it can exhaust the furnace body 1.

[0044] The temperature sensor 73 on the furnace body 1 detects the temperature of the furnace body 1, and when the temperature of the furnace body 1 gradually decreases, the temperature sensor 73 controls the first electric telescopic rod 7 to extend, and then the connecting plate 71 fixedly connected to the output end of the first electric telescopic rod 7 is driven to move away from the air duct 2, and then the control rod 51 connected to the connecting plate 71 through the bearing 72 is driven to move synchronously with the connecting plate 71, so that the push rod 55 on the control rod 51 pushes the lever 58, and since the lever 58 is fixedly connected to the plug rod 56, the plug rod 56 can be rotated, and then the blade 54 fixedly connected to the plug rod 56 rotates synchronously, and then the rotation angle of the blade 54 becomes larger, so that the blade 54 can have a larger air volume when rotating, and then the cooling effect of the furnace body 1 is enhanced, so that the furnace body 1 will not be damaged by thermal expansion and cold contraction due to sudden cooling at high temperature;

[0045] The temperature sensor 73 sets the operation of the first electric telescopic rod 7 according to the characteristics of the material of the furnace body 1 during use, and the stop ring 53 connected to the control rod 51 can limit the stroke of the control rod 51, so as to prevent the control rod 51 from being driven by the connecting plate 71 to slide too far away, so that the rotation angle of the blade 54 is too large and the air volume is not good, and the combined force of the torsional spring 57 on the plug rod 56 and the push rod 55 can stably maintain a certain angle when the blade 54 rotates and the push rod 55 does not push the lever 58.

[0046] When the rotation angle of the blade 54 increases to increase the air volume, the air inlet amount of the air inlet pipe 3 into the furnace body 1 also increases, and since the rotation angle of the blade 54 gradually changes, the air inlet amount gradually increases, and then the gradual increase of the air volume makes the air volume sensor 31 control the second electric telescopic rod 32 to gradually contract, and then the first circular block 33 fixedly connected to the second electric telescopic rod 32 gradually moves away from the inlet end of the cooling nitrogen inlet pipe 12, and then the inlet amount of the cooling nitrogen gradually increases, and the inlet cooling nitrogen is affected by the negative pressure in the furnace body 1 to enter the furnace body 1 to enhance the cooling of the furnace body 1;

[0047] In the initial state, the first circular block 33 blocks the cooling nitrogen inlet pipe 12, so that the cooling nitrogen cannot enter the furnace body 1, and then the furnace body 1 is prevented from being suddenly cooled by the forced cooling of the cooling nitrogen and being cracked.

[0048] When the cooling nitrogen is introduced, the piston cylinder 38 at the lower end of the cooling nitrogen inlet pipe 12 is affected by the cooling nitrogen to cool the air in the piston cylinder 38 and reduce the volume, and then the piston rod 39 slides into the piston cylinder 38, Figure 6As shown, when the piston rod 39 slides into the piston cylinder 38, the discharge pipe 35 is in communication with the extension pipe 36, and then the oxidant cleaning agent in the pressure tank 34 can flow through the discharge pipe 35 and the extension pipe 36 and be sprayed from the first atomizing nozzle 37 into the furnace body 1, so that the oxidant in the furnace body 1 is soaked with the cleaning agent, and the cleaning of the furnace body 1 is more convenient.

[0049] The air flowing into the piston cylinder 38 should have a certain pressure, and the pressure can offset the pressure generated by the pressure tank 34.

[0050] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
