Description

Technical Field

[0001] This utility model relates to the field of ball milling equipment technology, specifically to a ball milling equipment for the production of sintered corundum. Background Technology

[0002] A ball mill is a commonly used grinding or crushing equipment, essential for the production of chemical raw materials or sintered corundum. A search of existing technology (publication number: CN222918813U) reveals "a ball mill for chemical raw materials, relating to the field of ball mill technology, including a base plate and a ball mill cylinder. The base plate is respectively provided with a first vertical plate and a second vertical plate. One end of the ball mill cylinder has an open structure, and the open end of the ball mill cylinder is rotatably connected to the first vertical plate. The discharge end of the ball mill cylinder is rotatably connected to the second vertical plate. The first vertical plate is provided with a feed inlet, which communicates with the interior of the ball mill cylinder. A sieve cylinder is fixedly connected to the discharge end of the ball mill cylinder." This invention allows for the screening of chemical raw materials, and allows non-compliant chemical raw materials to be directly fed back into the ball mill cylinder for grinding, eliminating the need for manual collection and re-feeding. This significantly improves the convenience of using the device, reduces the workload of workers, and effectively increases work efficiency.

[0003] Although the ball mill for chemical raw materials mentioned in the aforementioned patent documents achieves the effect of further grinding, the raw materials discharged from the ball mill cylinder are not uniform in size and are mixed together. After entering the cylinder, large particles may form a layer of obstruction at the bottom of the cylinder, making it impossible to perform effective screening. Secondly, during use, the conveying of raw materials will generate a large amount of dust around the feed inlet and collection box, causing pollution to the surrounding environment. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, a ball milling device for the production of sintered corundum is provided to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a ball mill device for sintered corundum production is provided, comprising: a base, a set of vertical plates on the upper side of the base, a ball mill cylinder rotatably connected between the vertical plates, a feed inlet connected to one side of the ball mill cylinder, a conveying pipe connected to the outer side of the feed inlet, and a conveying cylinder connected to the other end of the conveying pipe, a dust removal assembly provided on the outer side of the conveying cylinder, the dust removal assembly including a dust suction component fixed to the outer wall of the conveying cylinder, a dust collection box connected to the outer end of the dust suction component through a dust suction pipe, and an exhaust fan connected to the other side of the dust collection box through a straight pipe, a screening box connected to one side of the ball mill cylinder near the feed inlet, a set of rollers rotatably connected inside the screening box, a transmission belt connected between the rollers, a scraper connected to the outer side of the transmission belt, a screen at the bottom of the screening box, an outlet at the bottom of the screen, a collection box below the outlet, and the outer side of the screening box connected to the conveying cylinder through a connecting pipe.

[0006] Furthermore, the vacuum cleaner includes a housing, and the housing has an inner cavity on its inner side, the inner cavity has an inner wall on its inner side, and the vacuum cleaner tube is connected to the inner cavity.

[0007] Furthermore, the inner wall is fixed to the outer wall of the conveying cylinder, and a mesh is provided between the inner wall and the conveying cylinder, with a filter screen inside the mesh.

[0008] Furthermore, a motor is installed on the upper side of the screening box, and a first synchronous belt is connected to the front side of the motor. The lower end of the first synchronous belt is connected to a second synchronous belt through a gear.

[0009] Furthermore, a drive shaft is fixed inside the roller, and the outer end of the drive shaft rotates through the wall of the screening box and connects with a gear.

[0010] Furthermore, the outer end of the scraper is provided with a toothed rack, and there is a gap between the toothed racks.

[0011] Furthermore, the scraper on the lower side of the transmission belt moves toward the connecting pipe, and there is a gap between the lower end of the scraper and the upper surface of the screen.

[0012] Furthermore, the end of the conveying pipe connected to the conveying cylinder is higher than the end connected to the feed inlet, and the feed inlet is connected to the ball mill cylinder through the pipe connected at the lower end, passing through the vertical plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The transmission belt and scraper inside the screening box allow the raw material exiting the ball mill cylinder to enter the screening box. At the same time, the motor is started, and the transmission belt is driven to rotate through the first and second synchronous belts, gears, drive shaft and shaft rollers. This drives the scraper to rotate, causing the scraper to scrape the raw material falling on the screen, pushing large particles towards the connecting pipe and then into the conveying cylinder. This avoids the accumulation of large particles on the screen, improves the flowability of the raw material on the screen, and thus improves the screening efficiency.

[0015] 2. By starting the exhaust fan, the dust removal components, including the outer shell, inner wall, and suction pipe, create a suction effect on the outside of the conveying cylinder through the mesh and inner cavity, thereby drawing the dust out into the dust collection box. At the same time, due to the negative pressure suction effect inside the conveying cylinder, a suction effect is also created on the connected conveying pipe, connecting pipe, and the inside of the screening box, achieving a dust removal effect around the feed inlet and collection box.

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 protection scope of the present utility model.

[0023] Reference Figures 1 to 5 As shown, this utility model provides a ball mill device for sintered corundum production, including: a base 1, a set of vertical plates 2 on the upper side of the base 1, a ball mill cylinder 3 rotatably connected between the vertical plates 2, a feed inlet 4 connected to one side of the ball mill cylinder 3, a conveying pipe 5 connected to the outside of the feed inlet 4, and a conveying cylinder 8 connected to the other end of the conveying pipe 5. The end of the conveying pipe 5 connected to the conveying cylinder 8 is higher than the end connected to the feed inlet 4, and the feed inlet 4 is connected to the ball mill cylinder 3 through the vertical plates 2 via a pipe connected to its lower end. A dust removal component 6 is provided on the outside of the conveying cylinder 8, and the dust removal component 6 includes a suction device fixed to the outer wall of the conveying cylinder 8. Dust collection component 63 is connected to a dust collection box 62 via a dust collection pipe 635 at its outer end. At the same time, a blower 61 is connected to the other side of the dust collection box 62 via a straight pipe. A screening box 7 is connected to one side of the feed inlet 4 of the ball mill cylinder 3. A set of rollers 741 are rotatably connected inside the screening box 7. A transmission belt 742 is connected between the rollers 741. A scraper 78 is connected to the outside of the transmission belt 742. A screen 77 is provided at the bottom of the screening box 7. An outlet 75 is provided at the bottom of the screen 77. A collection box 9 is provided below the outlet 75. The outside of the screening box 7 is connected to the conveying cylinder 8 via a connecting pipe 76.

[0024] In this embodiment, the base 1, vertical plate 2, ball mill cylinder 3, feed inlet 4, conveying pipe 5, and conveying cylinder 8 are all consistent with the working principle of the relevant structures involved in the prior art documents, that is, the above-mentioned technical features have been fully disclosed in the prior art documents.

[0025] Specifically, the outer wall of the ball mill cylinder 3 is provided with a large gear, which is driven by a drive device and a drive gear meshing with the large gear, thereby driving the ball mill cylinder 3 to rotate. At the same time, steel balls are provided inside the ball mill cylinder 3. The ball mill cylinder 3 is used to grind the raw materials during the sintering corundum production process.

[0026] Specifically, the dust collection box 62 is equipped with an air filter at the connection end with the exhaust fan 61 to achieve dust interception and filtration.

[0027] like Figure 1 and Figure 2In the process, the vacuum cleaner 63 includes a housing 631, and the housing 631 has an inner cavity 632 on its inner side. The inner cavity 632 has an inner wall 633 on its inner side. The vacuum cleaner pipe 635 is connected to the inner cavity 632. The inner wall 633 is fixed to the outer wall of the conveying cylinder 8. A mesh 634 is provided between the inner wall 633 and the conveying cylinder 8. A filter screen is provided inside the mesh 634.

[0028] Specifically, the outer shell 631 and the inner wall 633 are designed as an integral ring structure, and the outer wall of the outer shell 631 and the vertical plate 2 are connected by a fixing plate.

[0029] Specifically, six mesh holes 634 are equidistantly arranged around the circumference of the conveying cylinder 8. The mesh holes 634 penetrate the inner wall 633 and communicate with the inner cavity 632, and then the raw materials are intercepted through the filter screen.

[0030] like Figure 2 , Figure 3 and Figure 4 In the screening box 7, a motor 71 is installed on the upper side, and a first synchronous belt 72 is connected to the front side of the motor 71. The lower end of the first synchronous belt 72 is connected to a second synchronous belt 73 through a gear. A drive shaft 74 is fixed inside the shaft roller 741, and the outer end of the drive shaft 74 rotates through the box wall of the screening box 7 and is connected to the gear. The outer end of the scraper 78 is provided with a rack 781, and there is a gap between the racks 781. The scraper 78 on the lower side of the transmission belt 742 moves toward the connecting pipe 76, and there is a gap between the lower end of the scraper 78 and the upper surface of the screen 77.

[0031] Specifically, the output shaft of the motor 71 is equipped with a gear, and two gears are coaxially connected to the outer end of the drive shaft 74 directly below it. One gear is connected to the gear at the end of the motor 71 via a first synchronous belt 72, and the other gear is connected to the gear at the outer end of another drive shaft 74 via a second synchronous belt 73.

[0032] It should be noted that the gears mentioned above are actually synchronous belt pulleys.

[0033] Specifically, the gap between the racks 781 is smaller than the outer diameter of the raw material that does not conform to the size of the grinding particles, and larger than the outer diameter of the raw material that conforms to the size of the grinding particles.

[0034] As a preferred embodiment, the scraper 78 and the rack 781 are configured so that when the raw material is pushed, large particles of raw material can be pushed outward by the gap between the racks 781, while raw material of the size that meets the grinding particle size can be leaked out from the gap and then pass through the screen 77 and the outlet 75 into the collection box 9.

[0035] During operation, the raw material enters the ball mill cylinder through the feed inlet for grinding, and then enters the screening box from the other side. Utilizing the drive belt and scraper inside the screening box, the raw material exiting the ball mill cylinder enters the screening box. Simultaneously, the motor is started, driving the drive belt to rotate via the first and second synchronous belts, gears, drive shaft, and rollers. This rotation of the drive belt, in turn, drives the scraper to rotate, causing it to scrape the raw material falling onto the screen. Large particles are pushed towards the connecting pipe and then fed into the conveyor cylinder, preventing large particles from accumulating on the screen, improving the flowability of the raw material on the screen, and thus improving screening efficiency. The efficiency is improved by simultaneously starting the exhaust fan. Through the outer shell, inner wall, and suction pipe of the dust removal components, a suction effect is formed on the outside of the conveying cylinder through the mesh and inner cavity, thereby drawing the dust inside out into the dust collection box. At the same time, due to the negative pressure suction effect formed inside the conveying cylinder, a suction effect is also formed on the connected conveying pipe, connecting pipe, and the inside of the screening box, achieving the dust suction effect around the feed inlet and the collection box. Then, the filtered raw material is vertically conveyed by the conveying cylinder and guided by the conveying pipe, and re-enters the feed inlet, and then enters the ball mill cylinder for further grinding.

[0036] The ball mill device for sintered corundum production of this utility model can effectively solve the problems mentioned in the background technology. It achieves effective and efficient screening of the ground raw materials on the basis of the existing ball mill device technology for sintered corundum production, while also having a dust removal effect.
