Description

Technical Field

[0001] This invention belongs to the technical field of semi-coke screening, and specifically relates to a semi-coke particle size online control screening device. Background Technology

[0002] Semi-coke, a novel carbon material produced by burning refined coal lumps, has demonstrated immense application value in industrial production due to its high fixed carbon content, high resistivity, strong chemical activity, and extremely low levels of impurities such as ash, aluminum, sulfur, and phosphorus. Currently, semi-coke has gradually replaced metallurgical coke and is widely used in the production processes of calcium carbide, ferroalloys, ferrosilicon, and silicon carbide, becoming an indispensable and irreplaceable key carbon material in these industries.

[0003] Semi-coke has wide applications in many industries such as chemical engineering, metallurgy, and gasification, playing a vital role in replacing coke (metallurgical coke). However, different industries have significantly different requirements for the particle size of semi-coke when using it in production. Therefore, precise particle size screening is a crucial step in the semi-coke production process. With the rapid development of modern technology, the types of semi-coke particle size screening devices are constantly increasing, and their functions are becoming more and more sophisticated, aiming to achieve more efficient and convenient screening operations.

[0004] However, the existing semi-coke particle size screening devices still have the following drawbacks during use: 1. In the process of using existing semi-coke particle size screening equipment, due to its generally large production volume, the single screening volume is also relatively large, and the volume of the screening equipment is also large. Therefore, when screening semi-coke particles of different sizes, it is relatively difficult to adjust the particle size screening structure in the middle. It generally requires manual adjustment, which is slow, reduces screening efficiency, and increases the workload of the staff. 2. When using the existing semi-coke particle size screening device, after one batch of semi-coke has been screened, if the next batch of semi-coke is to be screened, the staff needs to manually feed the semi-coke particles into the device. Given the large screening volume, the amount of semi-coke that the staff pours in each time is also quite considerable. This process is not only time-consuming but also consumes a lot of manpower, greatly reducing the convenience of using the device.

[0005] Therefore, it is necessary to invent an online particle size control and screening device for semi-coke to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides an online particle size control and screening device for semi-coke, thereby solving the issues raised in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an online particle size control screening device for semi-coke, comprising a screening box and a screen cylinder, wherein an automatic particle size screening component replacement mechanism, a fixing component and a feeding mechanism are respectively provided on the outside of the screening box and inside the screen cylinder, wherein the screen cylinder is rotatably installed inside the screening box. The automatic particle size screening component replacement mechanism includes rotating shafts rotatably mounted on both sides of the top of the screening box. Support frames are fixedly mounted at both ends of the two rotating shafts. Connecting cylinders are fixedly mounted between one end of each of the four support frames. Two lead screws are rotatably connected between one end of each of the four support frames inside the two connecting cylinders. A sliding groove is opened in the middle of one side of each of the two connecting cylinders. A connecting ring is threadedly connected to the middle of the outer wall of each of the two lead screws. An L-shaped buckle is fixedly connected to one side of each of the four connecting rings, passing through the inner wall of the two sliding grooves. A first motor is fixedly connected to one end of each of the two lead screws, passing through the outer wall of one side of each of the two support frames. An installation groove is opened on one side of the screening cylinder. A protective plate is installed on the inner wall of the installation groove. Multiple screening holes are equidistantly opened on one side of the protective plate. A docking block is fixedly mounted in the middle of one side of the protective plate. Limiting slots are opened at both ends of the docking block. Preferably, the outer walls of one end of the two L-shaped buckles are respectively inserted and connected to the inner walls of the two limiting slots, and a second motor is installed on both sides of the screening box, and one end of the two rotating shafts is respectively fixedly connected to the output end of the two second motors.

[0008] Preferably, the fixing component includes connecting grooves formed on the inner walls of both ends of the screen cylinder, with movable strips slidably connected to the inner walls of both connecting grooves, and multiple retaining pins fixed at equal distances on one side of each of the two movable strips, with the outer wall of each retaining pin interlocking with the inner walls of both ends of the mounting groove.

[0009] Preferably, both ends of the screen cylinder are equipped with electric push rods, and the output ends of the two electric push rods are respectively fixedly connected to the other side of the two moving strips. Both ends of the protective plate are provided with multiple locking holes at equal intervals, and the outer wall of one end of each locking shaft is inserted and connected to the inner wall of each locking hole.

[0010] Preferably, a toothed ring is installed on the outer wall of one end of the screen cylinder, a gear is rotatably connected to one side of the inner wall of the screening box, and the outer wall of the gear meshes with the outer wall of the toothed ring. A third motor is installed on one side of the outer wall of the screening box, and one end of the gear is fixedly connected to the output end of the third motor. A discharge chute is installed in the middle position of the bottom of the screening box.

[0011] Preferably, the feeding mechanism includes a feeding bracket fixedly installed at one end of the top of the screening box, and a conveyor belt is installed on the inner wall of the feeding bracket.

[0012] Preferably, a support base plate is installed on the other side of the screening box, and multiple support rods are fixedly provided at equal intervals on the top of the support base plate, and one end of each support rod is fixedly connected to the bottom of the feeding bracket.

[0013] Preferably, a control panel is installed at one end of the outer wall of the screening box, and the first motor, the second motor, the electric push rod, the third motor, and the conveyor belt are all electrically connected to an external power supply through the control panel.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention utilizes an automatic particle size screening component replacement mechanism. When the particle size needs to be adjusted during the screening of semi-coke, the first and second motors drive the support frame, along with the connecting cylinder, to position it above the protective plate and engage with the L-shaped buckle. The support frame moves within the limiting slot on the top of the docking block and is then locked in place. Rotating the support frame again removes the protective plate. Similarly, protective plates with different screen hole inner diameters on the other side of the top of the screening box are rotated and engaged into the mounting slot on one side of the screen cylinder using the same mechanism. The fixing component then secures them. Throughout the process, there is no need for manual replacement of screening structures with different particle sizes. This method is fast and efficient, improving the screening efficiency of semi-coke particles while reducing the workload of the workers. 2. This invention, by setting up a feeding mechanism, allows for the direct pouring of semi-coke into one end of the bottom of the feeding support during the semi-coke screening process. After the semi-coke falls completely below the conveyor belt, the conveyor belt is started to transfer the semi-coke material to the top of the screening box. The top of the feeding support is aligned with the top of one end of the mounting groove. During feeding, the screen cylinder is rotated so that the mounting groove faces upward, and the protective plate is removed to achieve automatic feeding without the need for manual material handling, thus improving the convenience of using the device.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides, for example Figure 1-7 The semi-coke particle size online control screening device shown includes a screening box 1 and a screen cylinder 2. The device is characterized in that: an automatic particle size screening component replacement mechanism 3, a fixing component 4 and a feeding mechanism 9 are respectively provided on the outside of the screening box 1 and inside the screen cylinder 2, wherein the screen cylinder 2 is rotatably installed inside the screening box 1. The automatic particle size screening component replacement mechanism 3 includes rotating shafts 301 rotatably mounted on both sides of the top of the screening box 1. Support frames 302 are fixedly mounted at both ends of the two rotating shafts 301. Connecting cylinders 303 are fixedly installed between one end of each of the four support frames 302. Two lead screws 304 are rotatably connected between one end of each of the four support frames 302 inside the two connecting cylinders 303. A sliding groove 305 is provided in the middle of one side of each of the two connecting cylinders 303. Connecting rings 306 are threadedly connected to the middle of the outer wall of each of the four lead screws 304. One side of 306 is fixedly connected to the inner wall of two sliding grooves 305 with L-shaped buckles 307 respectively. One end of two screw rods 304 is fixedly connected to the outer wall of one side of two support frames 302 with a first motor 308 respectively. One side of the screen cylinder 2 is provided with an installation groove 309. The inner wall of the installation groove 309 is provided with a protective plate 310. Multiple screen holes 311 are provided at equal intervals on one side of the protective plate 310. A docking block 312 is fixedly provided in the middle position on one side of the protective plate 310. Both ends of the docking block 312 are provided with limit slots 313. In use, the protective plate 310 is installed in the mounting groove 309 on one side of the screen cylinder 2. Since a protruding limiting area is set at the lower edge of the inner wall of the mounting groove 309, the protective plate 310 can stay in the mounting groove 309 after it is inserted into the mounting groove 309. The fixing component 4 can be activated to fix it. Rotating the screen cylinder 2 will allow the semi-coke particles to be screened through the screen holes 311 on one side of the protective plate 310. If the semi-coke particle size needs to be adjusted midway, rotate the side of the screen cylinder 2 with the protective plate 310 to the top, and then start the second motor 314. Rotate the two support frames 302 through the rotating shaft 301 at one end of the top of the screening box 1, so that the connecting cylinder 303 at one end is above the protective plate 310. At this time, the two L-shaped buckles 307 in the sliding groove 305 on one side of the connecting cylinder 303 are aligned with the two limiting slots 313 on the top of the docking block 312. The inner wall shape of the limiting slots 313 is as shown in the instruction manual. Figure 3As shown, after the L-shaped buckle 307 is inserted, the first motor 308 is started to rotate the lead screw 304, causing it to slide relative to the connecting ring 306 in the connecting cylinder 303. This causes the L-shaped buckle 307 to be inserted into the depth of the two limiting slots 313, thus locking the protective plate 310 and releasing the locking component 4. Then, the second motor 314 is driven in the reverse direction, and the support frame 302 is rotated to remove the protective plate 310 of this size. Then, the second motor 314 at the other end is started, and the other end of the protective plate 310, which is fixed by the support frame 302 and the L-shaped buckle 307, is rotated and locked into the mounting slot 309. The inner diameter of the screen hole 311 of the protective plate 310 is different from that of the former, which can screen semi-coke particles of different sizes. After being inserted, the first motor 308 is started to make the lead screw 304 move with the connecting ring 306 and the L-shaped buckle 307, thereby disengaging from the limiting slot 313 and rotating the upright support frame 302. Finally, the protective plate 310 is fixed in the installation slot 309 by the fixing component 4, so that the screening operation of semi-coke particles of different sizes can be carried out. In the whole process, there is no need for the staff to manually change the screening structure of different particle sizes. It is fast and efficient, improves the screening efficiency of semi-coke particles, and reduces the workload of the staff.

[0021] The outer walls of one end of the two L-shaped buckles 307 are respectively inserted and connected to the inner walls of the two limiting slots 313. The two sides of the screening box 1 are equipped with second motors 314, and one end of the two rotating shafts 301 is respectively fixedly connected to the output end of the two second motors 314. The second motors 314 installed at both ends of the screening box 1 work alternately, so that the protective plates 310 of different inner diameter screen holes 311 on the screen cylinder 2 can be replaced alternately. Furthermore, the fixing component 4 includes connecting grooves 401 formed on the inner walls of both ends of the screen cylinder 2. The inner walls of the two connecting grooves 401 are slidably connected with moving strips 402. Multiple locking shafts 403 are fixed at equal distances on one side of the two moving strips 402. The outer wall of each locking shaft 403 is inserted and connected to the inner walls of both ends of the mounting groove 309. The fixing component 4 installed at both ends of the screen cylinder 2 does not affect the operation of the screen cylinder 2 rotating and screening semi-coke.

[0022] Both ends of the screen cylinder 2 are equipped with electric push rods 404, and the output ends of the two electric push rods 404 are fixedly connected to the other side of the two moving bars 402 respectively. Both ends of the protective plate 310 are provided with multiple locking holes 405 at equal distances, and the outer wall of one end of each locking shaft 403 is inserted and connected to the inner wall of each locking hole 405. Before and after the protective plates 310 with different screen hole 311 inner diameters are replaced on the screen cylinder 2, the electric push rods 404 are activated to push the moving bars 402 to slide in the connecting groove 401, and then the locking shafts 403 are extended and retracted in the inner walls on both sides of the mounting groove 309. When the protective plate 310 is disassembled and installed, it can be fixed and disassembled by inserting the locking shafts 403 into the locking holes 405 at both ends of the protective plate 310. The size of the protective plate 310 is consistent with the size of the mounting groove 309, so that after the protective plate 310 is installed, the positions of the locking shafts 403 and the locking holes 405 are exactly aligned. Furthermore, a toothed ring 5 is installed on the outer wall of one end of the screen cylinder 2, and a gear 6 is rotatably connected to one side of the inner wall of the screening box 1. The outer wall of the gear 6 meshes with the outer wall of the toothed ring 5. A third motor 7 is installed on one side of the outer wall of the screening box 1, and one end of the gear 6 is fixedly connected to the output end of the third motor 7. A discharge chute 8 is installed in the middle of the bottom of the screening box 1. When the screen cylinder 2 screens semi-coke, the third motor 7 is started, and the gear 6 is rotated to mesh with the toothed ring 5 to rotate, so that the screen cylinder 2 rotates and the semi-coke tumbles in it. Whenever the side with the protective plate 310 is at the bottom, the tumbling semi-coke can be fully screened through the screen hole 311 at its upper end, and the semi-coke particles under screening are discharged and collected through the discharge chute 8 to improve screening efficiency. The discharge chute 8 is inclined around the sides and at the discharge end to facilitate the rapid discharge of semi-coke. Furthermore, the feeding mechanism 9 includes a feeding bracket 901 fixedly installed at one end of the top of the screening box 1, and a conveyor belt 902 is installed on the inner wall of the feeding bracket 901.

[0023] A support base plate 903 is installed on the other side of the screening box 1. Multiple support rods 904 are fixedly mounted at equal intervals on the top of the support base plate 903, and one end of each support rod 904 is fixedly connected to the bottom of the feeding bracket 901. When feeding semi-coke, the semi-coke is poured directly into one end of the bottom of the feeding bracket 901, ensuring it falls completely below the conveyor belt 902. Then, the conveyor belt 902 is started to transfer the semi-coke material to the top of the screening box 1, as per the attached instruction manual. Figure 7As shown, the top of the feeding bracket 901 is aligned with the top of one end of the mounting groove 309. When feeding, the screen cylinder 2 is rotated so that the mounting groove 309 faces upwards, and the protective plate 310 is removed to achieve automatic feeding without the need for manual handling of materials, thus improving the convenience of using the device. In addition, the feeding mechanism 9 is supported and reinforced by the bottom support plate 903 and support rod 904, so that it can remain relatively stable during the feeding process, and the semi-coke material is not likely to fall into the outside of the screen cylinder 2 due to equipment vibration.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
