[0001] This utility model relates to the field of coal slime transfer machines, specifically a coal slime transfer machine with diversion function. Background Technology
[0002] Coal slime transfer machine is a specialized conveying and sorting equipment used in the coal washing, processing and transportation process to handle coal slime. It is mainly used to efficiently and stably transfer coal slime from one place to another, and may also have functions such as diversion, grading and concentration to meet different process requirements.
[0003] Coal slime is a high-moisture, high-viscosity, fine-particle byproduct generated during coal washing and processing. It is mainly composed of fine coal powder, gangue particles, clay minerals, and water. Traditional coal slime transfer machines with diversion function use hydrocyclones for diversion. Moreover, coal slime tends to adhere to the inner wall of the hydrocyclone during diversion and gradually accumulates over time, leading to an increased blockage rate in the diversion and conveying process. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, traditional coal slime transfer machines with diversion functions use hydrocyclones for diversion. However, coal slime tends to adhere to the inner wall of the hydrocyclone during diversion and gradually accumulates over time, leading to problems such as increased blockage rate during diversion and conveying. This utility model proposes a coal slime transfer machine with diversion function.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a coal slime transfer machine with diversion function, including a base plate, a base fixedly connected to one side of the base plate, a sludge settling cylinder fixedly connected to one side of the base, and an anti-blocking mechanism provided in the inner cavity of the sludge settling cylinder.
[0006] The anti-clogging mechanism includes a conical shell, one end of which is fixedly connected to one end of the sedimentation cylinder. A first rotating shaft is rotatably connected to the inner cavity of the base. A sliding plate is fixedly connected to the inner wall of the base. The surface of the first rotating shaft is rotatably connected to the inner cavity of the sliding plate. A scraper is fixedly connected to one end of the first rotating shaft. The surface of the scraper is slidably connected to the inner wall of the conical shell. A rotating plate is fixedly connected to the surface of the first rotating shaft. One side of the rotating plate is attached to the inner wall of the sedimentation cylinder. A diversion mechanism is provided at one end of the conical shell.
[0007] Preferably, the diversion mechanism includes a hydrocyclone housing, one end of which is fixedly connected to one end of a conical housing, a feed pipe is fixedly connected to the surface of the conical housing, a pump is provided at one end of the feed pipe, and an overflow pipe is fixedly connected to the top of the hydrocyclone housing.
[0008] Preferably, a first gear is fixedly connected to the surface of the first rotating shaft, and a second gear is rotatably connected to the inner cavity of the base, with the teeth of the second gear meshing with the teeth of the first gear.
[0009] Preferably, a first motor is fixedly connected to one side of the slide plate, a second rotating shaft is fixedly connected to the output end of the first motor, and one end of the second rotating shaft is fixedly connected to one side of the second gear.
[0010] Preferably, a connecting pipe is fixedly connected to one side of the base, and a concentration cylinder is fixedly connected to one end of the connecting pipe.
[0011] Preferably, a heating device is fixedly connected to the surface of the concentration cylinder, a through hole is opened on the surface of the concentration cylinder, and a gas recovery device is provided on the surface of the concentration cylinder.
[0012] Preferably, a top plate is fixedly connected to one end of the concentration cylinder, a second motor is fixedly connected to the inner wall of the top plate, and a third rotating shaft is fixedly connected to the output end of the second motor.
[0013] Preferably, a spiral fan blade is fixedly connected to the surface of the third rotating shaft, and one side of the spiral fan blade is attached to the inner wall of the concentration cylinder.
[0014] Compared with existing technologies, this utility model, by setting up an anti-clogging mechanism, allows coarse and heavy particles to be thrown towards the inner wall of the hydrocyclone shell under centrifugal force as the diversion mechanism operates. Then, under the action of gravity, they move downwards along the conical shell. However, large and heavy particles tend to accumulate in the settling cylinder, causing blockage. The rotation of the first rotating shaft drives the rotating plate fixedly connected to its surface to rotate. As the rotating plate rotates, it pushes the coarse and heavy particles in the settling cylinder to move, preventing particle accumulation and blockage. Furthermore, as the first rotating shaft rotates, it drives the scraper to rotate. The scraper can scrape off the coarse and heavy particles adhering to the inner wall of the conical shell and allow the coarse and heavy particles to be sent into the settling cylinder along the arc surface of the scraper. This achieves the effect of preventing blockage by coarse and heavy particles, solving the problems of traditional coal slime transfer machines with diversion function using hydrocyclones for diversion, and the fact that coal slime tends to adhere to the inner wall of the hydrocyclone during diversion and gradually accumulates over time, leading to an increased blockage rate during diversion and conveying.

Detailed Implementation
[0022] 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.
[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses a coal slime transfer machine with a diversion function. (Refer to...) Figures 1 to 3 A coal slurry transfer machine with diversion function includes a base plate 1, a base 2 fixedly connected to one side of the base plate 1, a slurry cylinder 3 fixedly connected to one side of the base 2, and an anti-blocking mechanism 4 provided in the inner cavity of the slurry cylinder 3.
[0025] The anti-clogging mechanism 4 includes a conical shell 401, one end of which is fixedly connected to one end of the sedimentation cylinder 3. A first rotating shaft 402 is rotatably connected to the inner cavity of the base 2. A sliding plate 403 is fixedly connected to the inner wall of the base 2. The surface of the first rotating shaft 402 is rotatably connected to the inner cavity of the sliding plate 403. A scraper 404 is fixedly connected to one end of the first rotating shaft 402, and its surface is slidably connected to the inner wall of the conical shell 401. A rotating plate 405 is fixedly connected to the surface of the first rotating shaft 402, with one side of the rotating plate 405 adhering to the inner wall of the sedimentation cylinder 3. A diversion mechanism 5 is provided at one end of the conical shell 401. By providing the anti-clogging mechanism 4, the diversion mechanism... During operation 5, coarse particles are thrown towards the inner wall of the hydrocyclone shell 501 by centrifugal force, and then move downward along the conical shell 401 under the action of gravity. However, coarse particles are prone to accumulate in the sedimentation cylinder 3, causing blockage. The first rotating shaft 402 rotates, driving the rotating plate 405 fixedly connected to its surface to rotate. As the rotating plate 405 rotates, it pushes the coarse particles in the sedimentation cylinder 3 to move, avoiding particle accumulation and blockage of the sedimentation cylinder 3. With the rotation of the first rotating shaft 402, the scraper 404 is driven to rotate. The scraper 404 can scrape off the coarse particles adhering to the inner wall of the conical shell 401 and allow the coarse particles to be sent into the sedimentation cylinder 3 along the arc surface of the scraper 404.
[0026] Reference Figure 3 The diversion mechanism 5 includes a hydrocyclone shell 501, one end of which is fixedly connected to one end of a conical shell 401. A feed pipe 502 is fixedly connected to the surface of the conical shell 401. A pump 503 is installed at one end of the feed pipe 502. An overflow pipe 504 is fixedly connected to the top of the hydrocyclone shell 501. By setting the diversion mechanism 5, the pump 503 fills the inner cavity of the hydrocyclone shell 501 with high-pressure coal slurry water through the feed pipe 502 in a direction tangential to the inner wall of the hydrocyclone shell 501, so that the coal slurry water forms a strong rotating flow field. Coarse and heavy particles such as gangue and large coal particles are thrown towards the inner wall of the hydrocyclone shell 501 by centrifugal force and slide down the conical shell 401 to the bottom and enter the settling cylinder 3, while fine and light particles such as fine coal slurry gather in the central low-pressure area and are discharged from the overflow pipe 504, thus realizing the diversion of coal slurry water.
[0027] Reference Figure 3 A first gear 6 is fixedly connected to the surface of the first rotating shaft 402, and a second gear 7 is rotatably connected to the inner cavity of the base 2. The teeth of the second gear 7 mesh with the teeth of the first gear 6. By setting the first gear 6 and the second gear 7, the second gear 7 rotates. Since the teeth of the second gear 7 mesh with the teeth of the first gear 6, the second gear 7 drives the first gear 6 to rotate, thereby the first gear 6 drives the first rotating shaft 402 to rotate.
[0028] Reference Figure 3A first motor 8 is fixedly connected to one side of the slide plate 403. A second rotating shaft 9 is fixedly connected to the output end of the first motor 8. One end of the second rotating shaft 9 is fixedly connected to one side of the second gear 7. By setting the first motor 8, the first motor 8 works and controls the second rotating shaft 9 fixedly connected to its output end to rotate, thereby the second rotating shaft 9 drives the second gear 7 fixedly connected to one end to rotate.
[0029] Reference Figure 4 A connecting pipe 10 is fixedly connected to one side of the base 2, and a concentration cylinder 11 is fixedly connected to one end of the connecting pipe 10. By setting the connecting pipe 10, coarse and heavy particles in the base 2 can enter the concentration cylinder 11 through the connecting pipe 10 for concentration.
[0030] Reference Figure 4 A heating device 12 is fixedly connected to the surface of the concentration cylinder 11. A through hole 13 is opened on the surface of the concentration cylinder 11. A gas recovery device 14 is provided on the surface of the concentration cylinder 11. By setting the heating device 12, the concentration cylinder 11 can be heated, so that the temperature of the coarse and heavy particles in the concentration cylinder 11 is raised, thereby evaporating the water absorbed by the particles. The heating device 12 is model QG-2000, and its structure includes a drying tube, a hot air generator, a cyclone separator and an induced draft fan. By setting the gas recovery device 14, the water vapor formed by the evaporation of water enters the gas recovery device 14 through the through hole 13. The gas recovery device 14 can absorb and store the water vapor, preventing the gas from escaping into the working environment and affecting the normal operation of other mechanisms. The gas recovery device 14 is model MGP-1000, and its structure includes a compressor unit, a membrane separation unit, a liquefaction device and a controller.
[0031] Reference Figure 5 One end of the concentration cylinder 11 is fixedly connected to a top plate 15, and a second motor 16 is fixedly connected to the inner wall of the top plate 15. The output end of the second motor 16 is fixedly connected to a third rotating shaft 17. By setting the second motor 16, the second motor 16 works and controls the rotation of the third rotating shaft 17 fixedly connected to its output end.
[0032] Reference Figure 5 A spiral fan blade 18 is fixedly connected to the surface of the third rotating shaft 17. One side of the spiral fan blade 18 is attached to the inner wall of the concentration cylinder 11. By setting the spiral fan blade 18, the spiral fan blade 18 rotates with the rotation of the third rotating shaft 17. As the spiral fan blade 18 rotates, the coarse and heavy particles in the concentration cylinder 11 are driven by the spiral fan blade 18 to move axially along the third rotating shaft 17, so that the concentrated coarse and heavy particles are discharged from the discharge port opened on the surface of the concentration cylinder 11.
[0033] Working principle: Pump 503 fills the inner cavity of hydrocyclone shell 501 with high-pressure coal slurry through feed pipe 502 in a direction tangential to the inner wall of hydrocyclone shell 501, creating a strong rotating flow field. Fine particles, such as micro-coal slurry, gather towards the central low-pressure area and are discharged from overflow pipe 504, thus diverting the coal slurry. Coarse particles, such as gangue and large coal particles, are thrown towards the inner wall of hydrocyclone shell 501 by centrifugal force and slide down the conical shell 401 to the bottom, entering the settling cylinder 3. The first motor 8 operates, controlling the rotation of the second rotating shaft 9 fixedly connected to its output end. The second rotating shaft 9 drives the second gear 7 fixedly connected to one end to rotate. Since the teeth of the second gear 7 mesh with the teeth of the first gear 6, the second gear 7 drives the first gear 6 to rotate, which in turn drives the first rotating shaft 402 to rotate. The rotation of the first rotating shaft 402 drives the scraper 404 to rotate. The scraper 404 can scrape off the coarse particles adhering to the inner wall of the conical shell 401 and allow the coarse particles to be fed into the settling cylinder 3 along the arc surface of the scraper 404. As the first rotating shaft 402 rotates, the rotating plate 405 fixedly connected to the surface of the first rotating shaft 402 rotates. As the rotating plate 405 rotates, it pushes the coarse particles in the settling cylinder 3 to move, preventing the particles from accumulating and clogging the settling cylinder 3. Then, the coarse particles enter the thickening cylinder 11 from the base 2 through the connecting pipe 10 and evaporate the water under the heating of the heating device 12. At the same time, the second motor 16 works and controls the third rotating shaft 17 fixedly connected to its output end to rotate, so that the spiral fan blade 18 rotates with the rotation of the third rotating shaft 17. Thus, the coarse particles in the thickening cylinder 11 are driven by the spiral fan blade 18 to move axially along the third rotating shaft 17, so that the concentrated coarse particles are discharged from the discharge port opened on the surface of the thickening cylinder 11.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
