[0001] This utility model belongs to the technical field of pitch coking equipment, and particularly relates to a hard carbon heat treatment device for pitch coke production. Background Art

[0002] The main body of the continuous carbonization rotary kiln for pitch is a rotating cylindrical body. Wet materials are continuously and quantitatively added from one end through a feeding device by a feeder. When passing through the inside of the cylinder, they come into effective contact with the hot air passing through the cylinder and are dried. Most of the dried products come out from the discharge port at the other end, and a small part of the finer products enter the separator together with the tail gas. The products are collected, and the tail gas is discharged into the atmosphere by a induced draft fan. During the drying process, the materials move from the higher end to the lower end under the action of gravity with the help of the slow rotation of the cylinder. There are forward baffles installed on the inner wall of the cylinder, which continuously lift and sprinkle the materials, increasing the heat contact surface of the materials to improve the drying rate and promote the forward movement of the materials. The heat carrier used in the drying process is the flue gas generated after burning coke oven gas and natural gas.

[0003] The rotary cylinders of existing rotary kilns are slightly inclined or horizontally arranged. The inclination of the rotary cylinder is not easy to adjust, and it is impossible to adjust the inclination of the rotary cylinder according to the characteristics of the materials to change the running speed of the materials in the rotary cylinder, which has certain limitations in use.

Specific embodiments

[0033] Please refer to Figure 1-12 , and the present utility model will be described in detail below with reference to the drawings and embodiments:

[0034] The hard carbon heat treatment device for pitch coke described in the utility model includes a rotary drum 1. The left end of the rotary drum 1 is rotatably connected to a left mounting plate 2, and the right end of the rotary drum 1 is rotatably connected to a right mounting plate 3. The bottom end of the right mounting plate 3 is hinged to the lower frame 4. An adjusting device 5 is arranged inside the frame 4, and the output end of the adjusting device 5 is connected to the left mounting plate 2. The adjusting device 5 is used to drive the left mounting plate 2 to perform an arc-shaped movement around the hinge point of the right mounting plate 3 and the frame 4, so as to achieve the purpose of adjusting the inclination of the rotary drum 1. A feeding device 6 is fixedly arranged inside the left mounting plate 2. The feeding pipe 7 of the feeding device 6 is rotatably connected to the left end of the rotary drum 1 and is communicated with the internal space of the rotary drum 1. The right part of the outer surface of the rotary drum 1 is rotatably connected to a discharge bin 8, and the discharge bin 8 is fixedly arranged with the right mounting plate 3. During use, the left mounting plate 2 and the right mounting plate 3 remain stationary, and the middle rotary drum 1 rotates. Pitch is added from the feeding device 6 and enters the rotary drum 1. A heating device is arranged on the rotary drum 1, and the heating device is used to turn the air parallel or countercurrent to the pitch in the rotary drum 1 into hot air. The pitch continuously enters the inside of the rotary drum 1 from the feeding device 6 at the left end. The pitch runs into the discharge bin 8 by the force of continuous feeding. The pitch is in full contact with the parallel or countercurrent hot air, so that the pitch is coked, and the coked pitch is discharged from the discharge bin 8.

[0035] In this embodiment, the frame 4 includes two side plates 9 arranged front and back. Between the two side plates 9, two end plates 10 are fixedly arranged. The adjusting device 5 includes threaded rods 11 that are rotatably connected to the two end plates 10. A driving sleeve 12 is threadedly connected to the outer surface of the threaded rod 11. A connecting rod 13 is hinged between the driving sleeve 12 and the left mounting plate 2. A motor 14 is fixedly arranged on the outer side surface of the left end plate 10. The output shaft of the motor 14 is fixedly arranged with the threaded rod 11. When the motor 14 rotates, it drives the threaded rod 11 to rotate. When the threaded rod 11 rotates, it drives the driving sleeve 12 to move left and right. Thus, the purpose of driving the left mounting plate 2 to rotate around the hinge point between the right mounting plate 3 and the side plate 9 through the connecting rod 13 is achieved, and the purpose of adjusting the inclination angle of the rotary drum 1 is realized. When the rotary drum 1 operates, it can be horizontal. The asphalt inside the rotary drum 1 is in full contact with the hot air flowing in parallel or in reverse for coking, and runs to the discharge bin 8 at the right end through continuous feeding pressure. In this case, the time for the asphalt to be heated and coked inside the rotary drum 1 is the longest. When the left end of the rotary drum 1 is lifted upward, increasing the inclination angle of the rotary drum 1, the driving force for the asphalt inside the rotary drum 1 to move to the right, in addition to the continuous feeding force, also has its own gravity to move to the right. During production, the inclination angle of the rotary drum 1 needs to be adjusted according to the characteristics of the asphalt. The adjusting device 5 also has the function of facilitating the final emptying of the rotary drum 1 when production is completed. If the rotary drum 1 is horizontal, the asphalt inside the rotary drum 1 will lose the force to move to the right without the continuous feeding effect, which is not convenient for the final emptying. By adjusting the inclination of the rotary drum 1 through the adjusting device 5, the materials inside the rotary drum 1 can be easily emptied.

[0036] Since the rotary drum 1 is large in size and heavy in mass, when the rotary drum 1 is in a horizontal state, when the rotary drum 1 rotates, due to the support of the frame 4, the movement is relatively stable. When the rotary drum 1 has a certain inclination, the left end of the rotary drum 1 completely relies on the support of the connecting rod 13, and the connecting rod 13 is in an inclined state, resulting in unstable operation of the rotary drum 1 in the inclined state. To solve this problem, in this embodiment, a first bottom plate 15 is fixedly arranged at the bottom end of the left mounting plate 2. When the rotary drum 1 is in a horizontal state, the lower end surfaces of the first bottom plate 15 are in contact with the upper end surfaces of the two side plates 9, achieving the purpose of the two side plates 9 supporting the left end of the rotary drum 1 through the first bottom plate 15. Bottom blocks 16 are fixedly arranged at the positions corresponding to the front and back of the outer side surfaces of the two side plates 9 and the first bottom plate 15. A damping device is arranged inside the bottom block 16. The output shaft 17 of the damping device protrudes from the upper end surface of the bottom block 16 and is fixedly provided with a pressing block 18. The inner side surface of the pressing block 18 is fixedly arranged with the first bottom plate 15. A damping failure mechanism is arranged on the damping device.

[0037] In this embodiment, the top end of the connecting rod 13 is hinged to the first bottom plate 15.

[0038] When it is necessary to adjust the inclination of the rotary cylinder 1, first open the damping failure mechanism to make the damping device fail, and then drive the threaded rod 11 to rotate through the motor 14, so that the threaded rod 11 drives the first bottom plate 15 to lift upward through the driving sleeve 12 and the connecting rod 13. The first bottom plate 15 drives the left end of the rotary cylinder 1 to lift upward through the left mounting plate 2, achieving the purpose of adjusting the inclination angle of the rotary cylinder 1. When the first bottom plate 15 moves upward, the first bottom plate 15 drives the output shaft 17 of the damping device to move upward. Since the damping rotating shaft is in a failure state, the damping device does not affect the upward movement of the first bottom plate 15; when the inclination of the rotary cylinder 1 is adjusted, close the failure device. When the rotary cylinder 1 is running, the generated vibration is transmitted to the first bottom plate 15 and the output shaft 17 of the damping device, so that the damping device plays a role in buffering vibration and shock absorption, increasing the smoothness of the operation of the rotary cylinder 1.

[0039] In this embodiment, the damping device includes an arc-shaped chamber 19 opened in the bottom block 16 in the vertical direction. The center of the arc-shaped chamber 19 is on the hinge axis of the rotary cylinder 1 and the right mounting plate 3. A piston 20 is slidably arranged in the arc-shaped chamber 19. The upper end surface of the piston 20 is coaxially and fixedly arranged with the output shaft 17. The arc-shaped chamber 19 above the piston 20 is the upper chamber, and the arc-shaped chamber 19 below the piston 20 is the lower chamber. The upper chamber and the lower chamber are connected through a channel 21 opened in the bottom block 16. A damping block 22 is fixedly arranged in the channel 21. A damping hole 23 is coaxially opened on the upper end surface of the damping block 22. The damping failure mechanism includes a connecting pipe 24 arranged on the bottom block 16. The top end of the connecting pipe 24 is connected to the upper chamber, and the bottom end of the connecting pipe 24 is connected to the lower chamber. A connecting valve 25 is installed on the pipe body of the connecting pipe 24 located outside the bottom block 16. The upper chamber and the lower chamber are filled with hydraulic oil.

[0040] When it is necessary to adjust the inclination of the rotary drum 1, first open the communication valve 25 so that the upper chamber and the lower chamber are connected through the communication pipe 24. Then, drive the threaded rod 11 to rotate through the motor 14, so that the threaded rod 11 drives the first bottom plate 15 to lift upward through the drive sleeve 12 and the connecting rod 13. The first bottom plate 15 drives the left end of the rotary drum 1 to lift upward through the left mounting plate 2, achieving the purpose of adjusting the inclination angle of the rotary drum 1. When the first bottom plate 15 moves upward, the first bottom plate 15 drives the output shaft 17 of the damping device to move upward. The output shaft 17 drives the piston 20 to move upward in the arc-shaped chamber 19 to compress the space of the upper chamber. The hydraulic oil in the upper chamber flows into the lower chamber through the communication pipe 24 and the communication valve 25. When the inclination of the rotary drum 1 is adjusted, close the communication valve 25. At this time, the vibration generated by the rotation of the rotary drum 1 is transmitted to the output shaft 17 through the first bottom plate 15, so that the output shaft 17 drives the piston 20 to move up and down in the arc-shaped chamber 19. The up and down movement of the piston 20 causes the spaces of the upper chamber and the lower chamber to change accordingly, and further causes the hydraulic oil in the upper chamber and the lower chamber to flow through each other through the channel 21 and the damping hole 23. However, since the diameter of the damping hole 23 is very small, when the hydraulic oil flows through the damping hole 23, the molecules in the hydraulic oil rub against each other to generate heat, converting the vibration of the mechanical operation into the heat of the hydraulic oil, achieving the damping effect and improving the smooth operation of the rotary drum 1.

[0041] To increase the smoothness of the up and down movement of the piston 20, a spring 26 is fixedly arranged in the arc-shaped chamber 19 below the piston 20. When the piston 20 moves up and down, the spring 26 plays a buffering role for the piston 20.

[0042] In this embodiment, the bottom end of the right mounting plate 3 is fixedly provided with a second bottom plate 27. A rotating shaft 28 is rotatably connected inside the right mounting plate 3. The left end of the rotating shaft 28 is fixedly arranged with the right end of the rotary drum 1. The rotary drum 1 is rotatably connected to the right mounting plate 3 through the rotating shaft 28. The outer surface of the discharge bin 8 is fixedly arranged with the right mounting plate 3 through two connecting rods 29. The discharge bin 8 is a ring body rotatably connected to the rotary drum 1, and an annular groove 30 is provided on the inner side surface of the ring body. A plurality of discharge ports 31 are provided along the circumference of the rotary drum 1 at a position corresponding to the ring body. When the rotary drum 1 rotates, the coked asphalt moving from the left continuously falls into the annular groove 30 of the stationary ring body through the discharge ports 31. A discharge pipe 32 is fixedly arranged at the lower part of the outer surface of the ring body. The top end of the discharge pipe 32 is communicated with the annular groove 30 of the ring body. The asphalt entering the annular groove 30 of the ring body is discharged through the discharge pipe 32.

[0043] In order to achieve the purpose of driving the rotating drum 1 to rotate, in this embodiment, the upper end surfaces of the first base plate 15 and the second base plate 27 are rotatably connected to the transmission shaft 33 through pillars. The transmission shaft 33 has two transmission shafts 33 respectively located on the front and rear sides of the rotating drum 1. Rotating wheels 34 are fixedly provided at both ends of the outer surface of the transmission shaft 33. The outer surface of the rotating wheel 34 contacts the outer surface of the rotating drum 1. The outer surface of the rotating drum 1 and the outer surface of the rotating wheel 34 that contact the rotating wheel 34 are both quenched. The transmission shaft 33 is driven by a power device, so that the transmission shaft 33 drives the rotating wheel 34 to rotate. The rotating wheel 34 drives the rotating drum 1 to rotate through the contact between the outer surface and the outer surface of the rotating drum 1, thereby achieving the purpose of driving the rotating drum 1 to rotate.

[0044] The working principle of the utility model is as follows: the asphalt is continuously heated in the rotary drum 1 from the feeding device 6, the power device drives the rotary drum 1 to rotate through the rotating wheel 34, the heating device is the existing technology, there are natural gas heating and induction coil heating, etc., the air flow in the rotary drum 1 has two modes of parallel and reverse to the running direction of the asphalt, the asphalt is run to the ring body by the force of continuous feeding and enters the annular groove 30 of the ring body through the discharge port 31 of the rotary drum 1, and then discharged through the discharge pipe 32, when the asphalt runs from left to right in the rotary drum 1, it is fully contacted with the parallel or reverse hot air to achieve the coking of the asphalt, and the asphalt is discharged from the discharge pipe 32. 2 discharges coked asphalt. In use, the motor 14 can be rotated to drive the left end of the rotary drum 1 to move upward, so that the rotary drum 1 is set to be higher on the left and lower on the right, which accelerates the speed of the asphalt running to the right. When the rotary drum 1 has a set inclination angle, the vibration generated during the operation of the rotary drum 1 is transmitted to the piston 20 through the output shaft 17, so that the piston 20 moves up and down. Through the up and down movement of the piston 20, the hydraulic oil in the upper and lower chambers flows through the damping hole 23. The hydraulic oil flowing through the damping hole 23 generates heat, so that the vibration is converted into heat, which starts the shock absorption effect and improves the stability of the operation of the rotary drum 1.
