Description

Technical Field

[0001] This utility model relates to the field of alumina processing technology, and in particular to an alumina ball mill. Background Technology

[0002] α-alumina can be obtained by grinding, screening, and removing impurities from alumina powder (mainly γ-alumina), followed by calcination with the addition of a mineralizing agent. In the alumina grinding process, ball mills are commonly used equipment. They grind alumina into fine powder by using rollers to drive the internal steel balls and materials to roll and rub against each other.

[0003] However, existing grinding machines have shortcomings. During material discharge, due to the lack of dust prevention measures, fine powder will generate dust, which will not only cause dust pollution to the surrounding air, but also the dust can be easily inhaled by people, threatening the health of workers.

[0004] Therefore, it is necessary to provide an alumina ball mill to solve the above-mentioned technical problems. Utility Model Content

A support frame is fixedly installed on the top of the support plate, and a U-shaped plate is hinged to the support frame; a hydraulic cylinder hinged to the top of the support plate, the output rod of which is hinged to the U-shaped plate; two rotating shafts rotatably mounted on the U-shaped plate, on which a single roller for ball milling alumina is fixedly mounted, and multiple strip plates are fixedly installed on the inner wall of the roller; a servo motor fixedly mounted on one side of the U-shaped plate, the output shaft of which is fixedly connected to one end of any one of the rotating shafts; a feed pipe fixedly mounted on the roller; a baffle mechanism mounted on the feed pipe for blocking alumina; and a dust-proof discharge mechanism mounted on the support plate for discharging alumina.

[0007] Preferably, the material blocking mechanism includes: a screw rotatably mounted on the feed pipe, a connecting plate threaded onto the screw, a baffle welded onto the connecting plate, and the baffle being slidably and sealingly connected to a sliding hole on the feed pipe.

[0008] Preferably, the dustproof discharge mechanism includes: a first electric push rod fixedly installed on the U-shaped plate, a support block fixedly installed on the output rod of the first electric push rod, a through pipe fixedly installed on the support block, and the through pipe slidably connected to the U-shaped plate; a flexible hose fixedly installed on the support plate, the top end of the flexible hose being fixedly connected to the bottom end of the through pipe; a dustproof plate fixedly installed on the flexible hose, the dustproof plate having a discharge port; and a second electric push rod fixedly installed at the bottom of the support plate, the output rod of the second electric push rod being fixedly connected to the top of the dustproof plate.

[0009] Preferably, a positioning block is fixedly installed on the roller, and the positioning block is rotatably connected to the screw.

[0010] Preferably, a sealing ring is fixedly installed at the top of the through pipe, and a collection box for collecting alumina is provided at the top of the base plate.

[0011] Preferably, a sealing gasket is fixedly installed at the bottom of the dustproof plate, and a round hole is provided on the sealing gasket, which is corresponding to the discharge port.

[0012] Preferably, a handwheel is fixedly installed at one end of the screw, and the screw is made of stainless steel.

[0013] Compared with related technologies, the alumina ball mill provided by this utility model has the following beneficial effects: This utility model provides an alumina ball mill. Through the use of a baffle mechanism, the feed pipe can be opened and closed. When open, it allows for easy feeding of alumina to be ground and steel balls into the rollers. When closed, it effectively prevents alumina from being discharged from the feed pipe. A servo motor drives the rollers to rotate, allowing the alumina and steel balls to roll and rub inside the rollers. Multiple strip plates also push the steel balls higher, which then strike the alumina below, achieving effective ball grinding. After the alumina is ground into fine powder, the servo motor is turned off, and the feed pipe can be manually rotated downwards. Then, a dustproof discharge mechanism seals the feed pipe and collection box. Thus, when the feed pipe is opened using the baffle mechanism, dust-free discharge is achieved. The entire process effectively suppresses dust diffusion, effectively solving the technical problem of existing alumina ball mills lacking dustproof measures during discharge operations, leading to fine powder dust pollution and threatening the health of workers.

[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] This utility model provides an alumina ball mill, such as Figure 1-3As shown, the alumina ball mill includes: a base plate 1, with multiple support legs fixedly installed on the top of the base plate 1, and a single support plate 2 fixedly installed on the top of the multiple support legs; a support frame 3 fixedly installed on the top of the support plate 2, and a U-shaped plate 4 hinged to the support frame 3; a hydraulic cylinder 5 hinged to the top of the support plate 2, with the output rod of the hydraulic cylinder 5 hinged to the U-shaped plate 4; two rotating shafts 6 rotatably mounted on the U-shaped plate 4, with a single roller 8 for ball milling alumina fixedly installed on the two rotating shafts 6, and multiple strip plates 9 fixedly installed on the inner wall of the roller 8; a servo motor 7 fixedly mounted on one side of the U-shaped plate 4, with the output shaft of the servo motor 7 fixedly connected to one end of any one of the rotating shafts 6; a feed pipe 10 fixedly mounted on the roller 8; a baffle mechanism for blocking alumina mounted on the feed pipe 10; and a dustproof discharge mechanism for discharging alumina mounted on the support plate 2.

[0019] In this embodiment, during use, the feed pipe 10 is opened using a baffle mechanism. Then, the alumina to be ground and the steel balls to be used are fed into the roller 8 through the feed pipe 10. After feeding, the feed pipe 10 is blocked using the baffle mechanism. Next, the servo motor 7 is started to drive the rotating shaft 6 to rotate. The rotating shaft 6 drives the roller 8 to rotate, allowing the alumina and steel balls to roll and rub inside the roller 8. Multiple strip plates 9 push the steel balls to a high position, then drop them onto the alumina below, thus improving the ball milling effect. Once the alumina is ball-milled into fine powder, the servo motor 7 is turned off. Then, the feed pipe 10 can be rotated to the lower position of the roller 8 by manually rotating the roller 8. Next, the through pipe 16 on the dust discharge mechanism can be connected to the feed pipe 10, and the dustproof plate 18 on the discharge mechanism can block the top of the collection box. Finally, the feed pipe 10 can be opened by the baffle mechanism, so that the powdered alumina can be discharged from the feed pipe 10 into the dust discharge mechanism, and then enter the collection box from the dust discharge mechanism. The whole process can effectively suppress the spread of dust to the surroundings and achieve dust-free discharge. To ensure sufficient discharge, the hydraulic cylinder 5 can be activated to drive the U-shaped plate 4 to rotate on the support frame 3, so that the roller 8 can be tilted, so that the ball-milled alumina can be better discharged from the feed pipe 10, which can effectively prevent alumina residue in the roller 8.

[0020] In a further preferred embodiment of the present invention, the material blocking mechanism includes: a screw 11 rotatably mounted on the feed pipe 10, a connecting plate 12 threadedly mounted on the screw 11, a baffle 13 welded on the connecting plate 12, and the baffle 13 being slidably and sealingly connected to a sliding hole on the feed pipe 10.

[0021] In this embodiment, the baffle mechanism is used to block alumina. When in use, rotating the screw 11 will cause the connecting plate 12 to move horizontally. The connecting plate 12 will cause the baffle 13 to slide on the sliding hole on the feed pipe 10. When the baffle 13 moves to the outside of the feed pipe 10, the feed pipe 10 can be opened, allowing feeding or discharging. When the baffle 13 moves to the inside of the feed pipe 10, the feed pipe 10 can be blocked, effectively preventing alumina in the roller 8 from being discharged from the feed pipe 10.

[0022] In a further preferred embodiment of this utility model, the dustproof discharge mechanism includes: a first electric push rod 14 fixedly installed on the U-shaped plate 4, a support block 15 fixedly installed on the output rod of the first electric push rod 14, a through pipe 16 fixedly installed on the support block 15, and the through pipe 16 slidably connected to the U-shaped plate 4; a flexible hose 17 fixedly installed on the support plate 2, the top end of the flexible hose 17 being fixedly connected to the bottom end of the through pipe 16; a dustproof plate 18 fixedly installed on the flexible hose 17, the dustproof plate 18 having a discharge port; and a second electric push rod 19 fixedly installed at the bottom of the support plate 2, the output rod of the second electric push rod 19 being fixedly connected to the top of the dustproof plate 18.

[0023] In this embodiment, the dust discharge mechanism is used to discharge alumina. During discharge, the feed pipe 10 can be rotated below the roller 8 by manually rotating the roller 8. Then, the first electric push rod 14 is activated to drive the support block 15 and the through pipe 16 to move upward, so that the top of the through pipe 16 is tightly pressed against the feed pipe 10. Then, the second electric push rod 19 is activated to drive the dustproof plate 18 to move downward, so that the bottom of the dustproof plate 18 contacts the collection box. At this time, the feed pipe 10 can be opened by the material blocking mechanism, so that the powdered alumina can be discharged from the feed pipe 10 into the through pipe 16 and the hose 17, and then discharged into the collection box from the outlet. The whole process can effectively suppress the spread of dust to the surroundings and realize dust-free discharge.

[0024] In a further preferred embodiment of the present invention, a positioning block is fixedly installed on the roller 8, and the positioning block is rotatably connected to the screw 11.

[0025] In this embodiment, the use of positioning blocks can provide better support for the screw 11, making the screw 11 more stable during use.

[0026] In a further preferred embodiment of the present invention, a sealing ring is fixedly installed on the top of the through pipe 16, and a collection box for collecting alumina is provided on the top of the base plate 1.

[0027] In this embodiment, the use of a sealing ring can improve the sealing performance when the through pipe 16 and the feed pipe 10 come into contact, and the use of a collection box can collect the alumina produced by ball milling.

[0028] In a further preferred embodiment of the present invention, a sealing gasket is fixedly installed at the bottom of the dustproof plate 18, and a round hole is provided on the sealing gasket, the round hole being arranged corresponding to the discharge port.

[0029] In this embodiment, the use of a sealing gasket can improve the sealing performance when the dustproof plate 18 contacts the collection box, so as to prevent the aluminum oxide from flowing out from the gap between the dustproof plate 18 and the collection box when collecting powdered aluminum oxide.

[0030] In a further preferred embodiment of the present invention, a handwheel is fixedly installed at one end of the screw 11, and the screw 11 is made of stainless steel.

[0031] In this embodiment, the use of a handwheel makes it easy for people to rotate the screw 11. The stainless steel screw 11 has good durability and corrosion resistance, making it suitable for long-term use.

[0032] In summary, compared with related technologies, this solution, through the use of a baffle mechanism, can open and close the feed pipe 10. When open, it allows for easy feeding of the alumina to be ground and the steel balls to be used into the roller 8. When closed, it effectively prevents the alumina inside the roller 8 from being discharged from the feed pipe 10. The servo motor 7 enables the rotating shaft 6 to drive the roller 8 to rotate, allowing the alumina and steel balls to roll and rub inside the roller 8. At this time, multiple strip plates 9 can also push the steel balls to a high position, which then smashes down onto the alumina below, thus achieving oxidation. In the effective ball milling of aluminum, after the alumina is ball-milled into fine powder, the servo motor 7 is turned off, and then the feed pipe 10 can be rotated downwards by manually rotating the roller 8. Then, the dustproof discharge mechanism can be used to seal the feed pipe 10 and the collection box. In this way, when the feed pipe 10 is opened by the baffle mechanism, dust-free discharge can be achieved. The whole process can effectively suppress the spread of dust to the surroundings, effectively solving the technical problem that existing alumina ball mills lack dustproof measures during discharge operations, resulting in fine powder dust, causing air dust pollution and threatening the health of workers.
