[0003] In the existing technology, the coke can is manually locked by rotation, but the temperature around the coke can is high, which poses a danger. Secondly, the automatic locking device for the coke can in the existing technology is located around the coke can, which causes the device to be affected by high temperature and affects its service life. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, an automatic locking device for rotating coke pots is provided to solve the problems mentioned in the background.

[0005] To achieve the above objectives, an automatic rotating locking device for coke ovens is provided, comprising: a bracket, a positioning seat fixed to the upper end of the bracket, a drive box fixed to the upper end of the positioning seat, and a shaft plate connected to the upper end of the drive box; a motor housed inside the drive box, a fan located below the motor, and coolant located below the fan; a double-threaded screw rotatably connected between the shaft plates, a threaded plate threaded to the outer side of the double-threaded screw, and an end plate connected between the threaded plates; a valve plate connected to the inner side of the end plate, and the valve plate slidably inserted into the inside of the coke oven cover; and the bracket fixed to the outer side of the coke oven cover by a connecting rod.

[0006] Furthermore, the coke oven cover is located on the top of the coke oven, and a guide groove is provided inside the coke oven cover. A feed inlet is vertically provided inside the coke oven cover, and a valve plate is slidably inserted into the guide groove.

[0007] Furthermore, the front end of the double-threaded screw is connected to a driven sprocket, and the output shaft end of the motor is connected to a driving sprocket, and a chain connects the driven sprocket and the driving sprocket.

[0008] Furthermore, the outer wall of the drive box is provided with heat dissipation holes, which are located on one side of the motor and on the upper side of the fan.

[0009] Furthermore, a fixing rod is connected to the lower end of the fan, and a partition is connected to the lower end of the fixing rod. A guide shroud is connected to the air intake side of the fan, and the guide shroud passes downward through the partition.

[0010] Furthermore, the partition is fixed to the inner wall of the drive box, and the partition is located above the coolant.

[0011] Furthermore, the coolant is provided with an air outlet pipe inside, and the lower end of the air outlet pipe is connected to a horizontal pipe. One end of the horizontal pipe passes through the wall of the drive box, and an air inlet pipe is connected to the outer end of the horizontal pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In use, the internal motor, along with the drive sprocket, chain, and driven sprocket connected to the outside of the motor, drives the double-threaded screw to move the screw plate away from the valve plate when the valve plate is opened. This, in turn, moves the end plate and valve plate away from the valve plate, thus opening the coke can lid. When closing, the motor is started in reverse, causing the valve plate to move closer, thus closing the coke can lid. In other words, the coke can lid is automatically locked and opened by rotating the double-threaded screw in both directions, avoiding manual intervention and improving operational safety.

[0014] 2. By utilizing the heat dissipation holes on the outside of the drive box and the fan installed on the underside of the motor, after the fan is started, outside air is drawn into the drive box through the air inlet pipe, horizontal pipe, and air outlet pipe. Then, as the air passes through the air outlet pipe, it is cooled by the coolant on the outside. This cool air is then blown out by the fan, enhancing the heat dissipation of the motor. At the same time, the air is exhausted through the heat dissipation holes, achieving airflow between the inside and outside, thereby providing high-temperature protection for the drive equipment and extending the service life of the equipment.

A motor 32 is provided inside the drive box 3, and a fan 34 is provided below the motor 32. Coolant 39 is provided below the fan 34. A double threaded screw 7 is rotatably connected between the shaft plates 8, and a threaded plate 4 is threaded to the outer side of the double threaded screw 7. An end plate 5 is connected between the threaded plates 4. A valve plate 12 is connected to the inner side of the end plate 5, and the valve plate 12 is slidably inserted into the inside of the coke can cover 6. The bracket 1 is fixed to the outer side of the coke can cover 6 by a connecting rod 11.

[0021] In this embodiment, the support 1 is lower than the upper edge of the coke oven body, and the coke oven cover 6 is located at the upper edge of the coke oven body. The support 1 is symmetrically arranged on the front and rear sides of the coke oven body.

[0022] Specifically, the outer shell of drive box 3 is made of heat-insulating material.

[0023] Specifically, the motor 32 is equipped with a unified starting circuit to achieve simultaneous forward or reverse starting. In the prior art, the synchronous starting of two motors 32 is a known technical field.

[0024] Specifically, the length and width of the end plate 5 are greater than those of the valve plate 12. When the valve plate 12 is closed, the end plate 5 seals the outer insertion interface of the coke can cover 6. Furthermore, slots and inserts are provided on the side where the two valve plates 12 meet, so that when the two valve plates 12 meet, the slots and inserts are connected.

[0025] Specifically, the two ends of the double-threaded screw 7 are connected to smooth shafts, and one end of the smooth shaft is rotatably connected to the shaft plate 8, while the other end of the smooth shaft rotatably passes through the shaft plate 8.

[0026] like Figures 1 to 4In the coke oven, the coke oven cover 6 is located at the top of the coke oven, and a guide groove is opened inside the coke oven cover 6. A feed inlet is vertically opened inside the coke oven cover 6. At the same time, the valve plate 12 is slidably inserted into the guide groove. The front end of the double threaded screw 7 is connected to the driven sprocket 9, and the output shaft end of the motor 32 is connected to the driving sprocket 33. A chain 10 is connected between the driven sprocket 9 and the driving sprocket 33. The outer wall of the drive box 3 has heat dissipation holes 31, and the heat dissipation holes 31 are located on one side of the motor 32 and above the fan 34. On the side, a fixing rod 35 is connected to the lower end of the fan 34, and a partition 36 is connected to the lower end of the fixing rod 35. A guide shroud 37 is connected to the air intake side of the fan 34, and the guide shroud 37 passes downward through the partition 36. The partition 36 is fixed to the inner wall of the drive box 3, and the partition 36 is located on the upper side of the coolant 39. An air outlet pipe 382 is provided inside the coolant 39, and a horizontal pipe 381 is connected to the lower end of the air outlet pipe 382. One end of the horizontal pipe 381 passes through the box wall of the drive box 3, and an air inlet pipe 38 is connected to the outer end of the horizontal pipe 381.

[0027] Specifically, the inside of the coke can cover 6 has a circular hole, which is connected to the guide groove. The valve plate 12 locks and opens the circular hole by moving in the guide groove.

[0028] Specifically, part of the chain 10 is located inside the drive box 3, and part is located on the upper side of the drive box 3. The top of the drive box 3 has a through hole that allows the chain 10 to pass through freely.

[0029] Specifically, the partition 36 divides the interior of the drive box 3 into two independent chambers, and the shroud 37 is provided with a sealing ring at the position where it passes through the partition 36, and the upper end of the shroud 37 is connected to the outer side of the air intake side of the fan 34.

[0030] It should be noted that after the air deflector 37 is connected to the fan 34, the air intake side of the fan 34 can only draw air from the inside of the air deflector 37.

[0031] Specifically, the air inlet pipe 38 is located outside the drive box 3, and a sealing ring is provided at the connection between the horizontal pipe 381 and the drive box 3 to prevent coolant leakage. Meanwhile, the air outlet pipe 382 is provided with multiple sets of pipes connected to the upper side wall of the horizontal pipe 381 and communicating with the horizontal pipe 381. Furthermore, the upper opening of the air outlet pipe 382 is higher than the liquid level of the coolant 39.

[0032] In operation, the internal motor, along with the externally connected drive sprocket, chain, and driven sprocket, drives the double-threaded screw to move the screw plate outward when the valve plate is opened. This movement of the end plate and valve plate opens the coke can lid. Conversely, the motor reverses direction to move the valve plate closer, closing the lid. The automatic locking and opening of the coke can lid is achieved through the forward and reverse rotation of the double-threaded screw, eliminating manual intervention and improving operational safety. Ventilation holes on the outside of the drive box and a fan below the motor draw in outside air through the inlet, horizontal, and outlet pipes. The air is then cooled by coolant in the outlet pipe and blown out by the fan, enhancing motor cooling. Simultaneously, air is exhausted through the ventilation holes, ensuring airflow and providing high-temperature protection for the drive equipment, extending its lifespan.

[0033] The automatic locking device for rotating coke ovens of this invention can effectively solve the problems mentioned in the background technology. It achieves the effect of automatically opening and locking the coke oven based on the existing automatic locking device technology for rotating coke ovens, and also has the effect of preventing high temperature heat dissipation for the driving equipment.
