Description

Technical Field

[0001] This utility model belongs to the field of calcined petroleum coke technology, and in particular relates to a pretreatment device for calcined petroleum coke. Background Technology

[0002] The core objective of a pretreatment unit for calcining petroleum coke is to optimize the characteristics of the raw materials (such as particle size, moisture, and impurity content) through a series of process steps so that they meet the requirements of the subsequent high-temperature calcination process, ensuring the stability of the calcination process, product quality, and equipment operating efficiency. Typically, the petroleum coke raw material needs to be crushed and screened during pretreatment.

[0003] Traditionally, after petroleum coke is crushed using a jaw crusher, it is fed into a screening device and screened through a screen plate. However, the screen plate usually has screening holes and is welded to the screening device. Furthermore, the screen plate is connected to multiple accessories, making it difficult to disassemble. When the screen plate is damaged after long-term use, it is difficult to replace it quickly. In addition, the raw material is discharged relatively quickly during the screening process, reducing the screening quality. Utility Model Content

[0004] The purpose of this invention is to provide a pretreatment device for calcined petroleum coke. By setting up a screening mechanism, specifically, when the screen needs to be replaced, the screws on the baffle are removed, and then the screws on the screen are removed to take out the screen. The new screen is then positioned in the mounting groove on the screening plate, and finally, the four corner mounting screws of the screen are fixed in place. This method allows for quick screen removal and replacement, is simple and convenient to operate, and is more efficient. Furthermore, during screening, the petroleum coke raw material is slowed down by the serpentine strips on the screen, thereby improving the screening effect. This solves the problem that traditional screening plates are installed on screening equipment by welding, and the screening plate is connected to multiple accessories, making it difficult to disassemble the screen plate and quickly replace it when it is damaged after long-term use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a pretreatment device for calcined petroleum coke, comprising a pretreatment chamber, a collection box inserted into the bottom of the pretreatment chamber, and a motor fixedly connected to the front of the pretreatment chamber, and further comprising:

[0007] The screening mechanism is located on the top of the pretreatment box. The screening mechanism includes a screening plate located on the top of the pretreatment box. A baffle is fixedly connected to the top of the screening plate by screws. A feed hopper is fixedly connected to the left side of the top of the screening plate. An installation groove is opened inside the screening plate. A screen is positioned inside the installation groove. A serpentine strip is fixedly connected to the top of the screen.

[0008] The screen is fixedly connected to the screening plate by screws, and the baffle is used to cover the top of the screening plate.

[0009] Furthermore, a rotating shaft is fixedly connected to both the front and back sides of the right end of the screening plate. The screening plate is rotatably connected to the pretreatment box via the rotating shaft. The screening plate is inclined and is set with the left side higher than the right side. Since the right side of the screening plate is rotatably connected to the pretreatment box via the rotating shaft, the left side of the screening plate can swing up and down repeatedly.

[0010] Furthermore, the feed hopper is equipped with a swing plate, and the front and back of the swing plate are fixedly connected to the second rotating shaft. The swing plate is rotatably connected to the feed hopper through the second rotating shaft. When the petroleum coke raw material enters the feed hopper, it will swing the swing plate. At the same time, the feed hopper will shake along with the screening plate, so that the swing plate can also swing.

[0011] The swing plate swings within the feed hopper, and the second rotating shaft supports the swing plate.

[0012] Furthermore, guide plates are fixedly connected to the left and right sides of the pretreatment box. The guide plates are inclined, with the side of the two guide plates that are close to each other being set at a lower position. The bottom of the guide plates extends to the inner part of the collection box, and the bottom of the guide plates is higher than the top of the collection box. The qualified petroleum coke raw material falls downward and is guided by the guide plates so that the petroleum coke raw material can smoothly enter the collection box.

[0013] Furthermore, an inner plate is fixedly connected to the left side of the inner wall of the pretreatment box, and two springs are fixedly connected to the top of the inner plate. The top of the springs is fixedly connected to the bottom of the screening plate, and the springs are used to drive the screening plate to rebound downwards. When the protrusion on the elliptical wheel leaves the screening plate, the screening plate will reset downwards by its own weight and the elastic force of the spring.

[0014] Furthermore, two rotating wheels are provided on the right side of the inner plate. A rotating rod is fixedly connected inside each rotating wheel. An elliptical wheel is fixedly connected to the side of each rotating wheel that is close to each other. The front of the rotating wheel is connected to the motor output end through a pin. The bottom of the screening plate is in contact with the outer surface of the elliptical wheel. The rotating wheel is located on the outside of the screening plate, and a gap is left between the rotating wheel and the screening plate. The rotating rod can drive the two rotating wheels and the two elliptical wheels to rotate simultaneously, so that the screening plate can swing back and forth.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, through the setting of a screening mechanism, specifically, when it is necessary to replace the screen, the screws on the baffle are removed and taken out, and then the screws on the screen are removed to take out the screen. The new screen is then positioned in the mounting groove on the screening plate, and then the four corner mounting screws of the screen are fixed. This method can quickly disassemble and replace the screen, is simple and convenient to operate, and is more efficient. Moreover, the petroleum coke raw material is slowed down by the serpentine strips on the screen during screening, thereby improving the screening effect of the petroleum coke raw material.

[0017] 2. This utility model uses a swing plate to specifically feed crushed petroleum coke raw materials into the feed hopper. The petroleum coke raw materials entering the feed hopper swing the swing plate, which rotates on the feed hopper via a rotating shaft, causing the petroleum coke raw materials to slowly fall onto the screening plate. This avoids feeding too much raw material at once, thereby significantly reducing the occurrence of raw material overflowing the screening plate.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a pretreatment device for calcined petroleum coke, including a pretreatment box 1, a collection box 11 inserted into the bottom of the pretreatment box 1, and a motor 12 fixedly connected to the front of the pretreatment box 1. It also includes:

[0030] Screening mechanism 2 is located on top of pretreatment chamber 1. Screening mechanism 2 includes a screening plate 21 on top of pretreatment chamber 1. A baffle 22 is fixedly connected to the top of screening plate 21 by screws. A feed hopper 23 is fixedly connected to the left side of the top of screening plate 21. An installation groove 212 is provided inside screening plate 21, and a screen 24 is positioned inside the installation groove 212. A serpentine strip 241 is fixedly connected to the top of screen 24. When screen 24 needs to be replaced, the screws on the baffle 22 are removed and taken out, and then screen 24 is replaced. The screen 24 can be removed by unscrewing the screws on the screen. The new screen 24 is then positioned in the mounting groove 212 on the screening plate 21. Finally, the four corner mounting screws of the screen 24 are fixed in place. This method allows for quick disassembly and replacement of the screen 24. The operation is simple and convenient, and the efficiency is higher. During screening, the petroleum coke raw material is slowed down by the serpentine strips 241 on the screen 24, thereby improving the screening effect of the petroleum coke raw material. The screen 24 is fixedly connected to the screening plate 21 by screws, and the baffle 22 is used to cover the top of the screening plate 21.

[0031] The right end of the screening plate 21 is fixedly connected to the front and back of the screen. The screening plate 21 is rotatably connected to the pretreatment box 1 through the screen. The screening plate 21 is inclined and is set with the left side higher than the right side.

[0032] Inside the feed hopper 23, there is a swing plate 231. The front and back of the swing plate 231 are fixedly connected to the rotating shaft 232. The swing plate 231 is rotatably connected to the feed hopper 23 through the rotating shaft 232. When the crushed petroleum coke raw material is put into the feed hopper 23, the petroleum coke raw material entering the feed hopper 23 will swing the swing plate 231. The swing plate 231 will rotate on the feed hopper 23 through the rotating shaft 232, so that the petroleum coke raw material will slowly fall onto the screening plate 21, avoiding too much raw material at one time, thereby greatly reducing the situation of raw material overflowing the screening plate 21. The swing plate 231 swings in the feed hopper 23, and the rotating shaft 232 is used to support the swing plate 231.

[0033] Guide plates 13 are fixedly connected to the left and right sides of the pretreatment box 1. The guide plates 13 are inclined. The side of the two guide plates 13 that is close to each other is set at the lower position. The bottom of the guide plate 13 extends to the inner position of the collection box 11, and the bottom of the guide plate 13 is higher than the top of the collection box 11.

[0034] An inner plate 14 is fixedly connected to the left side of the inner wall of the pretreatment box 1. Two springs 141 are fixedly connected to the top of the inner plate 14. The top of the springs 141 is fixedly connected to the bottom of the screening plate 21. The springs 141 are used to drive the screening plate 21 to rebound downward.

[0035] Two rotating wheels 15 are provided on the right side of the inner plate 14. A rotating rod 151 is fixedly connected inside the rotating wheel 15. An elliptical wheel 152 is fixedly connected to the side of the two rotating wheels 15 that are close to each other. The front of the rotating wheel 15 is connected to the output end of the motor 12 through a pin. The bottom of the screening plate 21 is in contact with the outer surface of the elliptical wheel 152. The rotating wheel 15 is located on the outside of the screening plate 21, and a gap is left between the rotating wheel 15 and the screening plate 21.

[0036] One specific application of this embodiment is:

[0037] In use, the motor 12 is first started to drive the rotating wheel 15 to rotate, and the two elliptical wheels 152 are rotated simultaneously through the rotating rod 151. At this time, the protrusion of the elliptical wheel 152 will push the left side of the screening plate 21 upward, and the screening plate 21 will drive the spring 141 to stretch. The right side of the screening plate 21 will rotate on the pretreatment box 1 through the rotating shaft 211. When the protrusion on the elliptical wheel 152 leaves the screening plate 21, the screening plate 21 will return to its original position downward by its own weight and the elastic force of the spring 141. This repetition will make the screening plate 21 vibrate continuously. Then, the crushed petroleum coke raw material is put into the feed hopper 23. The petroleum coke raw material entering the feed hopper 23 will swing the swing plate 231, and the swing plate 231 will... The petroleum coke raw material is slowly dropped onto the screening plate 21 by the rotation of the shaft 232 on the feed hopper 23. After falling onto the screening plate 21, the petroleum coke raw material is screened by the screen 24, and the qualified petroleum coke raw material falls downward and is guided by the guide plate 13 to smoothly enter the collection box 11. At the same time, the petroleum coke raw material is slowed down by the serpentine strips 241 on the screen 24, which prevents the petroleum coke raw material from being discharged from the screening plate 21 quickly, thereby improving the screening effect of the petroleum coke raw material. Finally, the larger particles of petroleum coke raw material are discharged from the right side of the screening plate 21. During the screening process, the baffle 22 blocks the petroleum coke raw material to prevent the petroleum coke raw material from overflowing.

[0038] When it is necessary to disassemble and replace the screen 24, remove the screws on the cover 22 to expose the screening plate 21, then remove the screws on the screen 24 to remove it. Place the new screen 24 into the mounting groove 212 on the screening plate 21 to position it, and then fix it with the four corner mounting screws. Finally, put the cover 22 back onto the screening plate 21 and fix it with the mounting screws. This method can quickly disassemble and replace the screen 24, and the operation is simple, convenient and efficient.
