Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnaces, in particular to a cooling water circulation device for a smelting furnace. Background Art

[0002] During the operation of a smelting furnace, extremely high temperatures will be generated. If not controlled, it will not only affect the normal operation of the smelting furnace, but may also cause damage to the equipment and even lead to safety accidents. Therefore, the role of the cooling water circulation device is crucial. By circulating the cooling water, the temperature of the smelting furnace can be effectively reduced, ensuring the continuity and safety of the smelting process.

[0003] After consulting the relevant patent document CN220018182U, there are still some problems with the existing cooling water circulation device for smelting furnaces. The current optimization solutions on the market mainly are: the output shaft of the motor rotates to drive the rotation of the rotating shaft, and through the cooperation of multiple chain wheels and chains, multiple rotating shafts rotate simultaneously. The rotation of the rotating shaft drives the rotation of the cooling fan blades, thereby reducing the temperature of the returned cooling water and reducing the time required for cooling the returned water. However, when this device is performing the cooling work, it cannot switch the cooling performance according to the temperature of the smelting furnace itself. When the temperature of the smelting furnace is relatively low, the cooling system still operates at a high power, resulting in a waste of resources and an increase in the smelting cost. To address the above problems, by setting a thick cooling pipe, a thin cooling pipe, a connector, and a switching mechanism, the cooling water circulation system can adjust the cold circulation power according to the problem of the smelting furnace, effectively reducing energy waste. By setting a water pump, a connecting piece, a rack plate, a driving gear, and a motor, when the power of the cooling system needs to be adjusted, only the motor needs to be started, so that the motor can drive the driving gear to move the rack plate, thereby driving the water pump to move, and further driving the water supply pipe to drive the switching mechanism to move, completing the docking with the thick cooling pipe or the thin cooling pipe, and completing the switching work, improving the switching efficiency, and avoiding damage caused by excessive internal temperature of the smelting furnace due to cooling interruption.

Connecting heads 4 are arranged at one ends of the thick cooling pipe 2 and the thin cooling pipe 3 far from the outer wall of the smelting furnace 1. A water inlet pipe 5 is fixedly connected to the circumferential side of the smelting furnace 1, and the water inlet pipe 5 is located on the circumferential side wall near the bottom of the smelting furnace 1. One end of the water inlet pipe 5 far from the circumferential side wall of the smelting furnace 1 is fixedly connected to a water storage tank 6. A bottom plate 7 is fixedly connected to the top of the water storage tank 6. A support 8 is fixedly connected to the left side of the bottom plate 7. A support platform 9 is fixedly connected to the top of the support 8. A chute 10 is opened inside the support platform 9. A slider 11 is slidably connected inside the chute 10. A water pump 12 is fixedly connected to the top of the slider 11. A water suction pipe 13 is fixedly connected to the right side of the water pump 12. A connecting piece 14 is fixedly connected to the left side of the water pump 12. A rack plate 15 is fixedly connected to the bottom of the connecting piece 14. A driving gear 16 is meshed with the left surface of the rack plate 15. A motor 17 is fixedly connected to the bottom of the driving gear 16. A water delivery pipe 18 is fixedly connected to the top of the water pump 12. A switching mechanism 19 is arranged at one end of the water delivery pipe 18 far from the water pump 12.

[0025] The thin cooling pipe 3 and the thick cooling pipe 2 are symmetrically distributed on the circumferential side of the smelting furnace 1. The water suction pipe 13 is made of rubber material, and one end of the water suction pipe 13 far from the side wall of the water pump 12 is fixedly connected to the top of the water storage tank 6. The motor 17 is fixedly connected to the left side of the support platform 9.

[0026] The connecting head 4 includes a pipe wall 401, and the pipe wall 401 is fixedly connected to the pipe walls of the thick cooling pipe 2 and the thin cooling pipe 3. A support plate 402 is fixedly connected to the inner wall of the pipe wall 401.

[0027] A contact rod 403 is fixedly connected to the surface of the support plate 402 near the outlet of the pipe wall 401, and the contact rod 403 extends from the surface of the support plate 402 to the outside of the pipe wall 401.

[0028] The switching mechanism 19 includes an outer chuck 191. An inner chuck 192 is arranged inside the outer chuck 191. A clamping groove 193 is opened between the outer chuck 191 and the inner chuck 192. A positioning plate 194 is fixedly connected to the inner wall of the outer chuck 191.

[0029] A slide bar 195 is slidably connected inside the positioning plate 194. One end of the slide bar 195 near the outlet of the outer chuck 191 is fixedly connected to a piston 196. The piston 196 is slidably connected to the inner wall of the inner chuck 192. A telescopic spring 197 is sleeved on the surface of the slide bar 195.

[0030] One end of the telescopic spring 197 is fixedly connected to the positioning plate 194, and the end of the telescopic spring 197 away from the positioning plate 194 is fixedly connected to the piston 196. The size of the inner chuck 192 matches the thickness of the pipe wall 401.

[0031] The working principle of a cooling water circulation device for a smelting furnace in an embodiment of the present application is as follows: When the temperature inside the smelting furnace 1 is too high, first start the motor 17, so that the motor 17 drives the driving gear 16 to rotate, thereby causing the rack plate 15 to move, and driving the synchronous movement of the water pump 12 through the connecting member 14. Due to the setting of the slider 11, the water pump 12 can move steadily inside the chute 10, improving the stability of the movement. During the movement of the water pump 12, the water supply pipe 18 drives the switching mechanism 19 to move synchronously. When the card slot 193 and the pipe wall 401 are completely engaged with each other, stop the motor 17. During the docking process of the card slot 193 and the pipe wall 401, the contact rod 403 will first push against the piston 196, causing the piston 196 to push the slide bar 195 to move towards the positioning plate 194, and the telescopic spring 197 will be compressed during the movement. When the piston 196 completely leaves the inside of the outer chuck 191, the card slot 193 is communicated with the inside of the outer chuck 191 and the inside of the water supply pipe 18, so that the water pumped out by the water pump 12 can enter the inside of the thick cooling pipe 2 through the inside of the card slot 193, realizing the circulation of the cooling water. Since the card slot 193 and the pipe wall 401 are hermetically docked, the piston 196 is just pushed open by the contact rod 403, so that the switching process will not cause water leakage. When switching to the thick cooling pipe 2, due to the larger heat dissipation area, the cooling of the inside of the smelting furnace 1 is more efficient, avoiding the phenomenon of high temperature in the smelting furnace 1. On the contrary, when switching to the thin cooling pipe 3, just reverse the motor 17 to complete the docking with the thin cooling pipe 3. This method can adaptively adjust the power of the cooling water circulation according to the temperature of the smelting furnace 1, reducing the waste of energy.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
