Description

Technical Field

[0001] This invention belongs to the field of ball mill technology, specifically a ball mill. Background Technology

[0002] Ball mills are core grinding equipment that rely on a rotating cylinder to drive grinding media (steel balls, steel segments, ceramic balls, etc.) to impact crush and friction grind materials. They are widely used in industries such as mining, building materials, cement, chemicals, metallurgy, new energy, and ceramics. They are key general-purpose equipment for processing materials from large pieces into fine powder and realizing mineral dissociation and raw material refinement.

[0003] Traditional ball mills have a fixed integrated structure where the lifting plate inside the cylinder rotates synchronously with the cylinder to lift and grind the material and grinding balls. This single function cannot simultaneously handle grinding operations and self-cleaning of the inner wall of the cylinder. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a ball mill that effectively solves the problem that traditional ball mills cannot simultaneously perform grinding operations and self-cleaning of the inner wall of the cylinder.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ball mill, comprising two end caps, two ring bodies, a cylinder, and a drive unit. The two end caps are respectively provided with a feed inlet and a discharge outlet, both end caps being fixedly installed. The two end caps are rotatably connected to the two ring bodies, and the two ring bodies are rotatably connected to both ends of the cylinder. A plate is provided along the axial direction between the two ring bodies. An annular groove and at least one mounting groove are provided within the ring body. An annular plate is movably installed within the annular groove. An external locking mechanism is provided between the annular plate and the annular groove. A locking block and an elastic element are movably installed within the mounting groove. The locking block is located between the annular plate and the elastic element, and an internal locking mechanism is provided between the locking block and the cylinder. A power element is fixed on the end cap, and the output end of the power element is fixed to the annular plate. The drive unit is used to drive the cylinder to rotate.

[0006] During ball milling, the inner locking mechanism fixes the ring body relative to the cylinder body, at which point the outer locking mechanism is released; during cleaning, the outer locking mechanism fixes the ring body relative to the end cap, at which point the inner locking mechanism is released.

[0007] Preferably, the drive unit includes a motor, a drive gear, and a driven gear. The motor is fixedly mounted, the drive gear is fixed on the motor output shaft, the drive gear meshes with the driven gear, and the driven gear is fixed on the cylinder.

[0008] Preferably, the inner locking mechanism includes an inner locking groove and an inner locking part that engage with each other. The inner locking groove is evenly distributed at the end of the cylinder, and the inner locking part is fixedly disposed at the end of the locking block.

[0009] Preferably, the external locking mechanism includes an external locking groove and an external locking part that engage with each other. The external locking groove is evenly opened in the annular groove, and the external locking part is fixedly mounted on the annular plate.

[0010] Preferably, there are multiple power components, which are evenly fixed on the end cover; the power components include a thumb cylinder.

[0011] Preferably, the elastic element includes a telescopic spring, which is disposed between the locking block and the mounting groove.

[0012] Preferably, the two rings are fixedly disposed at both ends of the plate, and the plate is fitted to the cylinder.

[0013] Preferably, the two ring bodies are respectively fixedly connected to a plate body by their respective lifting components, and the plate body is provided with a receiving cavity, with the end of the receiving cavity facing the lifting component being an open end.

[0014] Preferably, the lifting component includes an electric push rod, which is fixed to the ring body, and the output end of the electric push rod is fixed to the plate body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. During operation, the combination of the ring body, annular plate, and locking block allows the plate body to be fixed relative to the cylinder during ball milling, facilitating the transfer of grinding balls from a lower position to a higher position for grinding. During cleaning, the plate body is fixed relative to the end cap, making it convenient to remove foreign objects from the cylinder.

[0017] 2. During operation, the combination of the lifting components and the receiving cavity allows the grinding balls to be stored in the receiving cavity after the cleaning operation is completed, and the corresponding number of grinding balls can be released according to actual needs.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Depend on Figures 1 to 8 The present invention relates to a ball mill, comprising two end caps 1, two ring bodies 2, a cylinder 3, and a drive unit. The two end caps 1 are respectively provided with a feed inlet 4 and a discharge outlet 5, and both end caps 1 are fixedly installed. The two end caps 1 are rotatably connected to the two ring bodies 2, and the two ring bodies 2 are rotatably connected to both ends of the cylinder 3. A plate 6 is provided along the axial direction between the two ring bodies 2. An annular groove 7 and at least one mounting groove 8 are provided inside the ring body 2. An annular plate 9 is movably installed in the annular groove 7, and an external locking mechanism is provided between the annular plate 9 and the annular groove 7. A locking block 10 and an elastic element are movably installed in the mounting groove 8. The locking block 10 is located between the annular plate 9 and the elastic element, and an internal locking mechanism is provided between the locking block 10 and the cylinder 3. A power component is fixed on the end caps 1, and the output end of the power component is fixed to the annular plate 9. The drive unit is used to drive the cylinder 3 to rotate.

[0031] With this design, during use, materials and grinding balls can be fed into the inside of the cylinder 3 through the feed inlet 4. After grinding is carried out inside the cylinder 3, the ground materials can be discharged through the discharge outlet 5. The feed inlet 4 is positioned slightly higher than the discharge outlet 5 to facilitate material discharge.

[0032] This ball mill has two operating modes, as detailed below:

[0033] In the first mode, i.e., in ball milling mode: the power unit drives the annular plate 9 to move axially along the ring body 2, causing the annular plate 9 to move within the annular groove 7 and press against the locking block 10 in the mounting groove 8, thus compressing the elastic element. Simultaneously, the locking block 10 engages with the cylinder 3 via an internal locking mechanism, fixing the ring body 2 and cylinder 3 relatively. Next, the drive unit drives the cylinder 3 to rotate, and the cylinder 3, through the internal locking mechanism, drives the two ring bodies 2 to rotate synchronously. The two ring bodies 2 together drive the plate 6 on them to rotate synchronously. The plate 6 transfers the grinding balls from the lower part of the cylinder 3 to the higher part, where they fall, grinding the material.

[0034] The second mode, the cleaning state: After the grinding operation is completed, especially in wet grinding, it is necessary to clean the foreign matter remaining on the inner wall of the cylinder 3. The power component drives the annular plate 9 to move along the axial direction of the ring 2. After the annular plate 9 moves in the annular groove 7, the elastic component causes the locking block 10 to retract into the mounting groove 8. At this time, the inner locking mechanism releases the lock between the ring 2 and the cylinder 3. At the same time, the outer locking mechanism fixes the ring 2 and the end cap 1, completing the state switch. Then, the drive unit can drive the cylinder 3 to rotate, while the plate 6 between the two rings 2 remains stationary. The plate 6 can then scrape the inner wall of the cylinder 3 to remove foreign matter. Combined with subsequent manual high-pressure water gun cleaning, the cleaning operation inside the cylinder 3 can be achieved.

[0035] In short: During ball milling, the inner locking mechanism fixes the ring 2 relative to the cylinder 3, at which point the outer locking mechanism is released; during cleaning, the outer locking mechanism fixes the ring 2 relative to the end cap 1, at which point the inner locking mechanism is released.

[0036] Specifically, the drive unit includes a motor, a drive gear, and a driven gear. The motor is fixedly mounted, the drive gear is fixed on the motor output shaft, the drive gear meshes with the driven gear, and the driven gear is fixed on the cylinder 3.

[0037] This design allows the motor to drive the drive gear to rotate, which in turn drives the driven gear to rotate through meshing. The driven gear then drives the cylinder 3 to rotate, thus achieving the driving operation of the cylinder 3.

[0038] Specifically, the inner locking mechanism includes an inner locking groove 11 and an inner locking part 12 that engage with each other. The inner locking groove 11 is evenly distributed at the ends of the cylinder 3, and the inner locking part 12 is fixedly disposed at the ends of the locking block 10.

[0039] With this design, when the inner locking part 12 on the locking block 10 engages with the inner locking groove 11 on the cylinder 3, the ring 2 is fixed relative to the cylinder 3 and the two can rotate synchronously. When the inner locking part 12 on the locking block 10 disengages from the inner locking groove 11 on the cylinder 3, the ring 2 rotates relative to the cylinder 3 and the two do not rotate synchronously.

[0040] It should be noted that the inner locking part 12 can also be set at the end of the cylinder 3, and the inner locking groove 11 is correspondingly set on the locking block 10.

[0041] Specifically, the external locking mechanism includes an external locking groove 13 and an external locking part 14 that engage with each other. The external locking groove 13 is evenly opened in the annular groove 7, and the external locking part 14 is fixedly mounted on the annular plate 9.

[0042] With this design, when the outer locking part 14 on the annular plate 9 engages with the outer locking groove 13 in the annular groove 7, the ring body 2 is fixedly set with the opposite end cover 1, and the two remain stationary. When the outer locking part 14 on the annular plate 9 disengages from the outer locking groove 13 in the annular groove 7, the ring body 2 is rotated with the opposite end cover 1, and the two move asynchronously.

[0043] It should be noted that the outer card part 14 can also be provided on the annular groove 7, and correspondingly, the outer card groove 13 is provided on the annular plate 9.

[0044] Specifically, multiple power components are provided, and these power components are evenly fixed on the end cover 1; the power components include a thumb cylinder 15. With this design, the thumb cylinder 15 can drive the annular plate 9 to move along the axial direction of the ring body 2.

[0045] Specifically, the elastic element includes a telescopic spring 16, which is disposed between the locking block 10 and the mounting groove 8.

[0046] In this ball mill, the plate 6 has two connection methods, as detailed below:

[0047] The first connection method: two rings 2 are fixedly installed at both ends of the plate 6, and the plate 6 is fitted into the cylinder 3. With this design, the plate 6 can be moved synchronously by the two rings 2 to achieve scraping or feeding operations.

[0048] The second connection method: The two ring bodies 2 are respectively fixedly connected to the plate body 6 through their respective lifting components. The plate body 6 is provided with a receiving cavity 17, and the end of the receiving cavity 17 facing the lifting component is an open end.

[0049] With this design, when the plate 6 is attached to the cylinder 3, it can also perform the function of the first connection method. The difference is that after the cleaning operation is completed, the grinding balls gather at the bottom of the cylinder 3. At this time, the lifting device can be used to move the plate 6 outward, and then move the plate 6 downward. During the downward movement, some grinding balls will enter the receiving cavity 17 inside the plate 6. This cycle is repeated to collect the grinding balls. When it is necessary to release them, the plate 6 is simply rotated with the cylinder 3 to a position that is relatively vertical. Then, the lifting device can be used to move the plate 6, causing the grinding balls in the receiving cavity 17 inside the plate 6 to fall down. Then, the plate 6 returns to the position where it is attached to the cylinder 3.

[0050] It should be noted that two annular power supply plates can be set at the end of the end cover 1, and two contacts can be set on the ring body 2 accordingly. The two contacts slide in contact with the two power supply plates respectively, thereby realizing the power supply operation for the lifting component.

[0051] Specifically, the lifting component includes an electric push rod 18, which is fixed to the ring 2, and the output end of the electric push rod 18 is fixed to the plate 6.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
