Description

Technical Field

[0001] The utility model relates to the field of water-coal slurry production machinery, in particular to a water-coal slurry ball mill discharging structure. Background Art

[0002] The water-coal slurry ball mill is a kind of equipment used for industrial grinding. It is specially designed to grind materials and mix water-coal powder and water to form water-coal slurry. It can be dry-milled or wet-milled. It undertakes important production operations in the water-coal slurry slurry making process. The discharging process of the water-coal slurry ball mill is a key link in its entire work process. It is necessary to ensure that the material can flow smoothly while reducing the generation of excessively fine particles to maintain the quality and production efficiency of the water-coal slurry.

[0003] At present, when discharging the water-coal slurry ball mill, since the cylinder of the water-coal slurry ball mill is usually designed to be open at both ends, one end is the feed end, and the other end is the discharge end, the discharge end is slightly lower than the feed end, forming a certain inclination, and the material is discharged and collected through a discharge device connected to the discharge end. As the grinding process proceeds, the water-coal slurry material that meets the fineness requirements will gradually move to the discharge end. Due to the low position design of the discharge end, the finely ground material will overflow from the cylinder under the action of gravity and flow out of the ball mill through the discharge device, while the coarser particles will continue to circulate and grind in the cylinder because the gravity is insufficient to overflow; however, when discharging in the above manner, since the coal material has a certain humidity and high adhesion, the material is easy to adhere to the inner wall of the discharge device, which is inconvenient to clean, affects the collection effect, and has low work efficiency.

[0006] Furthermore, the vibration mechanism includes a fixed block, a vibrating block, a torsion spring and a driving assembly.

A vibrating block for vibrating the material on the inner wall of the collecting barrel is rotatably connected to the fixed block. A torsion spring is connected between the vibrating block and the fixed block. The vibrating block is in contact with the collecting barrel, and a driving assembly for driving the vibrating block to rotate is provided on the collecting barrel.

[0007] Furthermore, the driving assembly includes a pulling plate and a fixed rod, and the fixed rods are evenly spaced and connected to the top of the collecting barrel. A pulling plate for driving the vibration block to rotate is slidably connected between the fixed rods.

[0015] Compared with the prior art, the utility model has the following advantages: the utility model controls the operation of the motor so that the rotating rod drives the push plate to rotate. When the inclined surface of the push plate rotates to contact the convex block of the annular scraper, the annular scraper is driven to move upward and scrape the material on the inner wall of the collection barrel. The material on the inner wall can be scraped off while discharging the material, reducing residue and allowing the material to be discharged smoothly, thereby improving work efficiency and reducing subsequent operation steps.

[0026] like Figure 5 and Figure 6As shown, the vibration mechanism includes a fixed block 8, a vibration block 9, a torsion spring 10 and a driving assembly. The fixed blocks 8 are symmetrically fixedly connected to the upper left and right sides of the collecting bucket 1. The vibration block 9 is rotatably connected to the fixed block 8. A torsion spring 10 is connected between the vibration block 9 and the fixed block 8. The vibration block 9 is in contact with the collecting bucket 1, and the collecting bucket 1 is provided with a driving assembly.

[0027] like Figure 5 and Figure 6 As shown, the driving assembly includes a pulling plate 11 and a fixed rod 12. The fixed rods 12 are evenly spaced and fixedly connected to the top of the collecting barrel 1. The pulling plate 11 is slidably connected between the fixed rods 12. The lower part of the pulling plate 11 slides through the top of the collecting barrel 1. The lower part of the pulling plate 11 is a V-shaped inclined surface with even intervals. The left and right sides of the pulling plate 11 are respectively in contact with two vibration blocks 9.

[0028] like Figure 4 As shown, projections 61 are fixedly connected to the inner side of the annular scraper 6 at radially uniform intervals.

[0029] like Figure 2 and Figure 3 As shown, a guide plate 4 is also included. The upper part of the rotating rod 3 is fixedly connected with the guide plate 4, and the guide plate 4 is located inside the pushing plate 7.

[0030] like Figure 5 and Figure 6 As shown, it also includes a top block 13 . Four top blocks 13 are fixedly connected to the top of the guide plate 4 . The top blocks 13 are in contact with the inclined surface of the pulling plate 11 .

[0031] like Figure 7 As shown, a scraper frame 14 is also included. The lower part of the rotating rod 3 is connected to the scraper frame 14, and the scraper frame 14 contacts the lower part of the inner wall of the collecting barrel 1.

[0032] When the water-coal slurry ball mill needs to be used, the discharge structure is moved to the working area, and the upper end of the feed pipe 102 is connected to the discharge end of the water-coal slurry ball mill, and then the collection box is placed directly below the lower end of the discharge pipe 104, and then the water-coal slurry ball mill is controlled to work. After a certain period of time, the ground material falls into the collection bucket 1 through the feed pipe 102, and then the output shaft of the motor 2 is controlled to drive the rotating rod 3 to rotate, and the rotating rod 3 drives the guide plate 4, the push plate 7 and the scraper frame 14 to rotate. The falling material is guided by the rotating guide plate 4 to ensure smooth discharge of the material and ensure the material Quality, in this process, when the inclined surface on one side of the pushing plate 7 rotates to contact the protrusion 61 of the annular scraper 6, the annular scraper 6 will be driven by the pushing plate 7 to move upward, and when the annular scraper 6 moves to the top of the pushing plate 7, it moves downward along the inclined surface on the other side of the pushing plate 7 under the action of gravity to reset, and this process is cyclically performed with the continuous rotation of the pushing plate 7, driving the annular scraper 6 to move up and down reciprocatingly, so that the annular scraper 6 can scrape the material on the inner wall of the collecting barrel 1, so that the material on the inner wall can be scraped off while discharging, reducing the residue while making The material is discharged smoothly, the work efficiency is improved, and the subsequent operation steps are reduced. At the same time, the push plate 7 drives the top block 13 to rotate. When the top block 13 rotates to contact the inclined surface at the bottom of the pulling plate 11, the pulling plate 11 is driven to slide upward along the fixed rod 12, and the vibration block 9 is pulled to rotate by the left and right sides of the pulling plate 11. The torsion spring 10 is twisted and deformed, and the vibration block 9 is out of contact with the collection bucket 1. When the top block 13 rotates to disengage from the inclined surface at the bottom of the pulling plate 11, under the elastic force of the torsion spring 10, the vibration block 9 is driven to reverse and reset, so that the vibration block 9 is in contact with the collection bucket 1. This causes the collecting barrel 1 to be struck and vibrated, thereby reducing the adhesion of material on the inner wall of the collecting barrel 1. At the same time, the vibration block 9 drives the left and right sides of the pulling plate 11 to move downward and reset. This process is cyclically performed with the continuous rotation of the push plate 7, driving the pulling plate 11 to move up and down reciprocatingly, so that the two vibration blocks 9 can vibrate and shake off the material on the inner wall of the collecting barrel 1. The scraper frame 14 rotates and contacts the lower part of the inner wall of the collecting barrel 1, so that the material on the lower part of the inner wall of the collecting barrel 1 can be scraped off, and at the same time, the material is prompted to be discharged outward through the discharge pipe 104, thereby reducing material residue and improving the discharge efficiency.

[0033] After use, the water-coal slurry ball mill and the motor 2 are controlled to stop working. When the water-coal slurry ball mill stops discharging materials, the rotating rod 3 no longer drives the guide plate 4, the push plate 7 and the scraper frame 14 to rotate. Repeat the above steps to discharge materials from the water-coal slurry ball mill again.

[0034] like Figure 1 As shown, a blower 5 is also included, and the blower 5 is bolted to the upper rear side of the collecting barrel 1; the setting of the blower 5 can promote the flow of materials and assist in the discharge of materials when it is necessary to dry the materials or prevent the materials from agglomerating.

The middle part of the front side of the collecting barrel 1 is connected with the discharge pipe 103, and the valve 15 is rotatably connected to the discharge pipe 103; when the water-coal slurry ball mill is needed for dry grinding, the collecting bag is sleeved on the front end of the discharge pipe 103, and then the valve 15 is rotated to open, and then the motor 2 and the blower 5 are synchronously controlled to work, and while the material on the inner wall is being scraped off, the light material can be blown to the front side through the blower 5, and discharged into the collecting bag through the discharge pipe 103, thereby realizing the diversion of the material and ensuring the consistency of the material collection. After the collection is completed, the motor 2 and the blower 5 are synchronously controlled to stop working, and then the valve 15 is rotated to close, and the collecting bag is removed, which is convenient for the collection and processing of the material.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention.
