Description

Technical Field

[0001] This utility model relates to the technical field of discharge devices, and in particular to a discharge device for a calcined petroleum coke calcining furnace. Background Technology

[0002] In the processing of petroleum coke, existing calcining furnace discharge devices are relatively simple, typically only discharging the calcined petroleum coke without screening capabilities. This necessitates additional equipment or processes to screen the discharged petroleum coke, increasing the complexity and cost of the production process.

[0003] Moreover, traditional discharge devices are prone to blockage and stagnation of petroleum coke during the discharge process due to structural and operational limitations, which affects discharge efficiency.

[0004] In addition, some existing devices with screening processes have unreasonable screen plate structure designs, which cannot effectively classify and screen petroleum coke particles according to their size. Furthermore, the stability and support methods of the screen plates are insufficient, which can easily lead to malfunctions or poor screening results during long-term use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a discharge device for a calcined petroleum coke calcining furnace.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A discharge device for a calcined petroleum coke calciner includes a discharge pipe with at least two feeders fixedly installed above it. The discharge pipe contains a bottom support belt, a first screen frame, and a second screen frame. Two first support frames and one second support frame are fixedly installed on both sides of the bottom support belt, with the second support frame located between the two first support frames. A motor is fixedly installed on the side wall of each first and second support frame near the left side of the second screen frame. A second baffle and a first baffle are fixedly installed on the left and right side walls of the second and first screen frames, respectively, with each second baffle facing the first support frame and each first baffle facing the second support frame. Side sliders are fixedly installed on both sides of the first and second screen frames. A groove is formed on the side wall of each first and second support frame, and each side slider is located within the groove.

[0010] Preferably, a connecting belt is fixedly installed between the upper end of the bottom support belt and the first screen frame. Screen plates are fixedly installed on the inner walls of both the first and second screen frames. At least two screen holes are opened through the top of each screen plate. Each screen hole is conical. At least two arc-shaped blocks are fixedly installed on the surface of each screen plate. Each arc-shaped block is located between two screen holes.

[0011] Preferably, a spring is fixedly installed between the top and bottom of each side slider and the top and bottom of the slide groove, and a rotating blade is fixedly installed at the end of each motor output shaft. The rotating blades located on the side walls of the first support frame and the second support frame can contact the first baffle and the second baffle, respectively.

[0012] (III) Beneficial Effects

[0013] 1. Petroleum coke first falls onto the screen plate of the second screen frame. Petroleum coke particles smaller than the screen holes will fall downwards. The petroleum coke falls onto the screen plate of the first screen frame. Petroleum coke particles smaller than the screen holes of the first screen frame will continue to fall. The petroleum coke will fall onto the bottom support belt. The bottom support belt, the first screen frame, and the second screen frame are in an inclined state. Therefore, the petroleum coke will fall along the bottom support belt, the first screen frame, and the second screen frame. At the same time, four motors are started. The motors drive the rotating blades to hit the second baffle and the first baffle. At this time, the first screen frame and the second screen frame will vibrate. Because the bottom support belt is made of a soft material, the vibration of the first screen frame and the second screen frame will cause the bottom support belt to shake. At this time, the petroleum coke will fall along the bottom support belt, the first screen frame, and the second screen frame. This device uses vibration to fall petroleum coke, which can realize the discharge of material and also perform the function of screening material, greatly improving the discharge capacity of petroleum coke.

[0014] 2. When the rotating blade strikes the second baffle and the first baffle, it will cause the first and second screen frames to shake. The vibration of the first and second screen frames will cause the side sliders on the side walls to vibrate. The rotating blade will vibrate in the groove and cause the springs on the upper and lower sides to compress and deform. The supporting force of the spring below each side slider is greater than that above, which can stably support the first and second screen frames when not in use. The screen plates on the first and second screen frames have different sizes of screen holes, which can be used to screen different types of petroleum coke. At the same time, the screen holes on the screen plates can prevent petroleum coke from temporarily remaining on the screen plates and improve the efficiency of petroleum coke movement.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the overall concept of the technical solution in this application embodiment is as follows:

[0022] To address the problems existing in the prior art, this utility model provides a discharge device for a calcined petroleum coke calcining furnace, including a discharge pipe 1. At least two feeders 11 are fixedly installed above the discharge pipe 1. Inside the discharge pipe 1, a bottom support belt 14, a first screen frame 16, and a second screen frame 17 are arranged. Two first support frames 12 and one second support frame 13 are fixedly installed on both the left and right sides of the bottom support belt 14. The second support frame 13 is located between the two first support frames 12. A motor 25 is fixedly installed on the side wall of each first support frame 12 and second support frame 13 near the left side of the second screen frame 17. Petroleum coke falls onto the screen plate 2 on the surface of the first screen frame 16. When the petroleum coke particles are smaller than the screen holes 21 on the surface of the first screen frame 16, they continue to fall onto the bottom support belt 14. The bottom support belt 14, the first screen frame 16, the second screen frame 17, the second screen frame 18, the second screen frame 19, the second screen frame 10, the second screen frame 11, the second screen frame 11, the second screen frame 16, the second screen frame 17, the second screen frame 18, the second screen frame 19, the second screen frame 1 ... The first screen frame 16 and the second screen frame 17 are tilted as a whole. Therefore, the petroleum coke will fall down along the bottom support belt 14, the first screen frame 16 and the second screen frame 17. At the same time, four motors 25 are started. The motors 25 drive the rotating blades 26 to hit the second baffle 19 and the first baffle 18. At this time, the first screen frame 16 and the second screen frame 17 will vibrate. The second baffle 19 and the first baffle 18 are fixedly installed on the left and right side walls of the second screen frame 17 and the first screen frame 16, respectively. Each second baffle 19 faces the first support frame 12, and each first baffle 18 faces the second support frame 13. Side sliders 23 are fixedly installed on the left and right sides of the first screen frame 16 and the second screen frame 17. Each side wall of the first support frame 12 and the second support frame 13 has a groove 27, and each side slider 23 is located in the groove 27.

[0023] A connecting belt 15 is fixedly installed between the upper end of the bottom support belt 14 and the first screen frame 16. Screen plates 2 are fixedly installed on the inner walls of both the first screen frame 16 and the second screen frame 17. At least two screen holes 21 are perforated above each screen plate 2, and each screen hole 21 is conical. When the rotating blade 26 impacts the second baffle 19 and the first baffle 18, it causes the first screen frame 16 and the second screen frame 17 to shake. The vibration of the first screen frame 16 and the second screen frame 17 causes the side sliders 23 on the side walls to vibrate. The rotating blade 26 vibrates within the groove 27, and also causes the springs 24 on the upper and lower sides to compress and deform. Each side... The supporting force of the spring 24 below the slider 23 is greater than that above, which can stably support the first screen frame 16 and the second screen frame 17 when not in use. At least two arc-shaped blocks 22 are fixedly installed on the surface of each screen plate 2. Each arc-shaped block 22 is located between two screen holes 21. Springs 24 are fixedly installed between the top and bottom of each side slider 23 and between the top and bottom of the slide groove 27. Rotating blades 26 are fixedly installed at the end of the output shaft of each motor 25. The rotating blades 26 located on the side walls of the first support frame 12 and the second support frame 13 can contact the first baffle 18 and the second baffle 19 respectively.

[0024] Working principle:

[0025] In the first step, petroleum coke enters the discharge pipe 1 through the feeder 11. The petroleum coke first falls onto the screen plate 2 on the surface of the second screen frame 17. Petroleum coke particles smaller than the screen holes 21 fall downwards. The petroleum coke falls onto the screen plate 2 on the surface of the first screen frame 16. Petroleum coke particles smaller than the screen holes 21 on the surface of the first screen frame 16 continue to fall. The petroleum coke falls onto the bottom support belt 14. The bottom support belt 14, the first screen frame 16, and the second screen frame 17 are all inclined, so the petroleum coke falls along the bottom support belt 14, the first screen frame 16, and the second screen frame 17. At the same time, the start-up... Four motors 25 are activated, and the motors 25 drive the rotating blades 26 to strike the second baffle 19 and the first baffle 18. At this time, the first screen frame 16 and the second screen frame 17 will vibrate. Since the bottom support belt 14 is made of a soft material, the vibration of the first screen frame 16 and the second screen frame 17 will cause the bottom support belt 14 to shake. At this time, the petroleum coke will fall down along the bottom support belt 14, the first screen frame 16 and the second screen frame 17. By using the vibration to fall the petroleum coke, this device can achieve the function of screening while discharging the material, which greatly improves the petroleum coke discharge capacity.

[0026] In the second step, the motors 25 on the side walls of the two first support frames 12 operate synchronously, and the motors 25 on the side walls of the two second support frames 13 operate synchronously. The rotation of the motors 25 will drive the rotating blades 26 at the output end to rotate. The rotating blades 26 are double-headed. When the rotating blades 26 hit the second baffle 19 and the first baffle 18, they will cause the first screen frame 16 and the second screen frame 17 to shake. The vibration of the first screen frame 16 and the second screen frame 17 will cause the side sliders 23 on the side walls to vibrate. The rotating blades 26 vibrate in the slide groove 27 and cause the springs 24 on the upper and lower sides to compress and deform. The supporting force of the springs 24 below each side slider 23 is greater than that above, which can stably support the first screen frame 16 and the second screen frame 17 when not in use. The screen holes 21 on the screen plates 2 of the first screen frame 16 and the second screen frame 17 are of different sizes, which can be used to screen different types of petroleum coke. At the same time, the screen holes 21 on the screen plates 2 can prevent petroleum coke from being temporarily retained on the screen plates 2, thereby improving the efficiency of petroleum coke movement.

[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
