Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of coal mine equipment, and in particular relates to a heavy medium cyclone separator. Background Technology
[0002] Heavy medium hydrocyclones are common equipment for separating clean coal and middlings. Their working principle is as follows: the medium enters the first stage of the hydrocyclone tangentially through the feed pipe at a certain pressure, generating a centrifugal force field within the separation cylinder and forming a downward internal spiral flow and an upward external spiral flow. At this time, the material (raw coal) is fed into the inner cyclone of the first stage of the hydrocyclone through the feed pipe in a central feeding manner. Under the action of centrifugal force, coal particles rapidly stratify along the hydrocyclone center to the wall according to different densities.
[0003] When using existing equipment, the material may get stuck at the discharge port due to the different shapes of the materials during the discharge process after sorting, which reduces the working efficiency of the device. Therefore, we propose a heavy medium cyclone separator. Utility Model Content
[0004] The purpose of this utility model is to provide a heavy medium cyclone separator. Through the control mechanism and the screening mechanism, it solves the problem that when the existing equipment is in use, the material may get stuck at the discharge port due to the different shapes of the materials during the discharge process after separation, which reduces the working efficiency of the device.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a heavy medium hydrocyclone sorting device, including a hydrocyclone body, a discharge port on the inner wall of the hydrocyclone body, a filling port on the inner wall of the end of the hydrocyclone body away from the discharge port, and a control mechanism on the outer wall of the hydrocyclone body.
[0007] The control mechanism includes a conveying pipe, the outer wall of which is slidably connected to the outer wall of the discharge port. Several bolts are threaded onto the inner wall of the conveying pipe, and the outer walls of these bolts are threaded onto the inner wall of the hydrocyclone body. A motor frame is fixedly connected to the outer wall of the conveying pipe at the end furthest from the discharge port. A first motor is fixedly connected to the outer wall of the motor frame. A conveying rod is fixedly connected to the bottom output end of the first motor via a coupling. The outer wall of the conveying rod is rotatably connected to the inner wall of the conveying pipe. A limit groove is formed on the inner wall of the hydrocyclone body at the end closest to the conveying rod, and a baffle is slidably connected to the inner wall of the limit groove.
[0008] Furthermore, the inner wall of the baffle is threaded with several threaded rods, the outer walls of the several threaded rods are rotatably connected to the inner wall of the limiting groove, a pulley is fixedly connected to the outer wall of the threaded rod away from the limiting groove, a belt is drivenly connected to the outer wall of the pulley, and a screening mechanism is provided on the outer wall of the hydrocyclone body.
[0009] Furthermore, the screening mechanism includes several limiting rods, the outer walls of which are fixedly connected to the inner wall of the injection port, and several sliding grooves are provided on the inner wall of the injection port near the limiting rod.
[0010] Furthermore, a filter plate is slidably connected to the inner wall of the second slide groove, and the inner wall of the filter plate is slidably connected to the outer wall of the limiting rod. Several limiting shafts are fixedly connected to the outer wall of the filter plate, and a connecting rod is rotatably connected to the outer wall of the limiting shaft.
[0011] Furthermore, the inner wall of the end of the connecting rod away from the limiting shaft is rotatably connected to the second limiting shaft, and the outer wall of the end of the injection port near the second limiting shaft is rotatably connected to several third limiting shafts. A gear disk is fixedly connected to the outer wall of the third limiting shaft near the second limiting shaft, and the outer wall of the gear disk is fixedly connected to the outer wall of the second limiting shaft.
[0012] Furthermore, a rotating shaft is rotatably connected to the inner wall of the end of the injection port near the gear disk, and an L-plate is fixedly connected to the outer wall of the end of the injection port near the rotating shaft.
[0013] Furthermore, a second motor is fixedly connected to the outer wall of the L-plate, and a drive shaft is fixedly connected to the bottom output end of the second motor via a coupling.
[0014] Furthermore, gears are fixedly connected to the outer walls of both the transmission shaft and the rotating shaft. Several gears are fixedly connected to the outer wall of the rotating shaft near the gear disk, and the outer walls of the gears mesh with the outer walls of the gear disk.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model incorporates a pulley on the threaded rod. When the equipment is in use, starting the first motor causes the conveying rod to rotate, accelerating the material discharge rate. When the discharge speed of the conveying pipe needs to be controlled, rotating the right threaded rod causes the right pulley to rotate, which in turn causes the belt to rotate. This belt then drives the left pulley to rotate, which in turn causes the left threaded rod to rotate. When multiple threaded rods rotate simultaneously and in the same direction, the discharge rate of the device can be accelerated, preventing blockage. Furthermore, it allows users to freely control the discharge speed of the device according to their specific needs.
[0017] 2. This utility model incorporates a second limiting shaft on the gear disc. When the equipment is in use, starting the second motor causes the transmission shaft to rotate, which in turn rotates the gears on the transmission shaft. Because multiple gears mesh with each other, the rotation of the gears on the transmission shaft drives the gears on the rotating shaft to rotate, causing the rotating shaft to rotate. This rotating shaft then drives multiple second gears to rotate, causing the gear disc to rotate on the third limiting shaft. This achieves the effect of filtering the material during the feeding process, preventing the presence of large stones or other impurities. Simultaneously, it vibrates the material, breaking it into smaller pieces to prevent blockage at the feeding port.
[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

Detailed Implementation
[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-5 As shown, this utility model is a heavy medium cyclone separator, including a cyclone body 1. The inner wall of the cyclone body 1 is provided with a discharge port 101. The inner wall of the cyclone body 1 away from the discharge port 101 is provided with a feed port 102. The outer wall of the cyclone body 1 is provided with a control mechanism 2. Through the feed port 102, the material can be put into the cyclone body 1 in time for processing and sorting. At the same time, since the feed port 102 is conical, the material drop can be reduced.
[0029] The control mechanism 2 includes a conveying pipe 201, the outer wall of which is slidably connected to the outer wall of the discharge port 101. Several bolts 202 are threaded onto the inner wall of the conveying pipe 201, and the outer walls of these bolts 202 are threaded onto the inner wall of the hydrocyclone body 1. These bolts 202 securely install the conveying pipe 201 at the discharge port 101, preventing it from falling off. The conveying pipe 201 also limits the direction of material transport, preventing material spillage. A motor frame 203 is fixedly connected to the outer wall of the end of the conveying pipe 201 furthest from the discharge port 101. A first motor 204 is fixedly connected to the outer wall of the motor frame 203. A conveying rod 205 is fixedly connected to the bottom output end of the first motor 204 via a coupling. When the first motor 204 is started, its rotation drives the conveying rod 205 to rotate, allowing the material in the conveying pipe 201 to be transported out more quickly, preventing it from accumulating inside and causing blockages. The outer wall of the conveying rod 205 is threaded onto the inner wall of the hydrocyclone body 1. The inner wall of the conveying pipe 201 is rotatably connected. A limiting groove 206 is formed on the inner wall of the hydrocyclone body 1 near the conveying rod 205. A baffle 207 is slidably connected to the inner wall of the limiting groove 206. Several threaded rods 208 are threadedly connected to the inner wall of the baffle 207. By controlling the position of the baffle 207 within the limiting groove 206, the discharge rate of material from the conveying pipe 201 can be controlled. The outer walls of the several threaded rods 208 rotate with the inner wall of the limiting groove 206. The threaded rod 208 is connected to a pulley 209 fixedly on the outer wall of the end away from the limiting groove 206. A belt 210 is connected to the outer wall of the pulley 209. A screening mechanism 3 is provided on the outer wall of the hydrocyclone body 1. The belt 210 can drive the pulley 209. When the threaded rod 208 is rotated, the rotation of the threaded rod 208 can drive the pulley 209 on the threaded rod 208 to rotate, which in turn drives the belt 210 to rotate. The rotation of the belt 210 can drive the pulley 209 on the right side to rotate.
[0030] The screening mechanism 3 includes several limiting rods 301. The outer walls of the limiting rods 301 are fixedly connected to the inner wall of the inlet 102. Several sliding grooves 302 are provided on the inner wall of the inlet 102 near the limiting rods 301. These sliding grooves 302 limit the movement trajectory of the filter plate 303, ensuring that the filter plate 303 can only slide within the sliding grooves 302. Simultaneously, the limiting rods 301 make the movement of the filter plate 303 smoother. The filter plate 303 is slidably connected to the inner wall of the sliding grooves 302. The inner wall of the filter plate 303 is slidably connected to the outer wall of the limiting rods 301. Several limiting shafts 304 are fixedly connected to the outer wall of the filter plate 303. The outer wall of 4 is rotatably connected to a connecting rod 305. When the second limiting shaft 306 moves, it can drive the connecting rod 305 to move, causing the limiting shaft 304 to move, and then drive the filter plate 303 to slide in the second sliding groove 302. The inner wall of the end of the connecting rod 305 away from the limiting shaft 304 is rotatably connected to the second limiting shaft 306. The outer wall of the end of the injection port 102 near the second limiting shaft 306 is rotatably connected to several third limiting shafts 307. The outer wall of the third limiting shaft 307 near the second limiting shaft 306 is fixedly connected to a gear disk 308. The gear disk 308 can limit the second limiting shaft 306 to prevent it from falling off, and at the same time, it can make the second limiting shaft 306 only rotate eccentrically around the third limiting shaft 307.
[0031] The outer wall of the gear disk 308 is fixedly connected to the outer wall of the limiting shaft 306. A rotating shaft 309 is rotatably connected to the inner wall of the end of the injection port 102 near the gear disk 308. An L-plate 310 is fixedly connected to the outer wall of the end of the injection port 102 near the rotating shaft 309. The L-plate 310 can fix the position of the second motor 311, preventing the second motor 311 from changing its position due to its own shaking during operation, thus affecting subsequent normal transmission. The second motor 311 is fixedly connected to the outer wall of the L-plate 310. The bottom output end of the second motor 311 is fixedly connected to a transmission shaft 312 via a coupling. Gears 313 are fixedly connected to the outer walls of both the transmission shaft 312 and the rotating shaft 309. The gears 313 can rotate... Shaft 309 serves a transmission function. When the second motor 311 is started, the rotation of the second motor 311 can drive the transmission shaft 312 to rotate, causing the gear 313 on the transmission shaft 312 to rotate, which in turn drives the gear 313 on the rotating shaft 309 to rotate, causing the rotating shaft 309 to rotate. Several gears 314 are fixedly connected to the outer wall of the end of the rotating shaft 309 near the gear disk 308. The outer wall of the gears 314 meshes with the outer wall of the gear disk 308, and the gears 314 can provide a transmission function for the gear disk 308. When the rotating shaft 309 rotates, it can drive multiple gears 314 to rotate simultaneously. Since the gears 314 mesh with the gear disk 308, the rotation of the gears 314 can drive the gear disk 308 to rotate.
[0032] One specific application of this embodiment is:
[0033] When the equipment is needed, 201 is first installed at the discharge port 101 using bolts 202. Then, the first motor 204 is started. The rotation of the first motor 204 drives the conveyor rod 205 to rotate, accelerating the material discharge rate. When it is necessary to control the discharge speed of the conveyor pipe 201, the right threaded rod 208 is rotated. The rotation of the right threaded rod 208 drives the right pulley 209 to rotate, causing the belt 210 to rotate. The rotation of the belt 210 drives the left pulley 209 to rotate, which in turn causes the left threaded rod 208 to rotate. When multiple threaded rods 208 rotate simultaneously and in the same direction, the baffle 207 can slide within the limiting groove 206. By controlling the position of the baffle 207 within the limiting groove 206, the material discharge speed can be controlled. The material is injected into the hydrocyclone body 1 through the inlet 102. Then, the second motor 311 is started. The rotation of the second motor 311 drives the transmission... The rotation of shaft 312 causes gear 313 on transmission shaft 312 to rotate. Since multiple gears 313 mesh with each other, the rotation of gear 313 on transmission shaft 312 can drive gear 313 on rotating shaft 309 to rotate, causing rotating shaft 309 to rotate. The rotation of rotating shaft 309 can drive multiple gears 314 to rotate, causing gear disk 308 to rotate on limiting shaft 307. The rotation of gear disk 308 can drive limiting shaft 306 to make eccentric circular motion around limiting shaft 307, which in turn causes connecting rod 305 to make eccentric circular motion. The movement of connecting rod 305 can drive limiting shaft 304 to move, causing filter plate 303 to slide in sliding groove 302. Sliding groove 302 can correct the eccentric circular motion of filter plate 303 into linear reciprocating motion along the direction of sliding groove 302, thereby vibrating the material and crushing it. At the same time, it can prevent material from accumulating on filter plate 303, which would reduce the working efficiency of the device.
