[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-3 As shown, the present invention proposes an ultrafine fly ash ball mill, including a ball mill body 1, a feeding cylinder 2, and a support block 6. The feeding cylinder 2 is horizontally arranged, with one end connected to the discharge end of the ball mill body 1. The bottom end of the feeding cylinder 2 is provided with multiple discharge holes and discharge outlets. The support block 6 is connected to the bottom end of the feeding cylinder 2. The multiple discharge holes and discharge outlets are located on both sides of the support block 6. A drive assembly for driving the powder movement is detachably provided inside the feeding cylinder 2. A sliding vertical first collection assembly is provided at the lower end of the multiple discharge holes. The first collection assembly can be moved to fit against the lower end of the feeding cylinder 2. A second collection assembly is detachably provided below the discharge outlet.

[0023] When using this device, the material from the ball mill body 1 enters the conveying cylinder 2. The conveying cylinder 2 is equipped with multiple discharge holes and discharge outlets, and is equipped with a movable first collection component and a detachable second collection component, which can effectively separate powders of different fineness. The finer powders are discharged through the discharge holes and collected by the first collection component, while the larger particles (i.e., completely crushed coal ash) are discharged through the discharge outlets and collected by the second collection component. This solves the problem in the prior art where incompletely crushed materials are directly discharged, affecting subsequent processing. This solution can collect the crushed coal ash powder at the discharge end of the ball mill and automatically classify it, thereby effectively preventing incompletely crushed coal ash from being mixed in with the crushed coal ash and affecting subsequent production.

[0024] Furthermore, this application also proposes that the drive assembly includes a cover plate 3 and a first motor 4. The cover plate 3 is attached to one end of the feed cylinder 2 away from the ball mill body 1 and is detachably connected to it. The cover plate 3 is provided with a first through hole. The auger is rotatably disposed inside the feed cylinder 2, and its output end passes through the first through hole. The other end of the cover plate 3 is connected to the first motor 4. The output shaft of the first motor 4 is coaxially connected to the output end of the auger.

[0025] Therefore, this technical solution achieves effective conveying of powder in the feed cylinder 2 by setting a detachable drive component. The auger rotates under the drive of the first motor 4, pushing the powder from the end of the ball mill body 1 to the discharge port. The design of the cover plate 3 not only ensures the installation stability of the drive component, but also facilitates maintenance and replacement.

[0026] Furthermore, this application also proposes that the end of the conveying cylinder 2 facing the cover plate 3 is provided with a threaded blind hole, the cover plate 3 is provided with a first through hole corresponding to the threaded blind hole, the first bolt 5 passes through the first through hole and extends into the threaded blind hole, the first bolt 5 is threadedly connected to the conveying cylinder 2, and the first bolt 5 abuts against the cover plate 3.

[0027] Therefore, this technical solution enables the quick assembly and disassembly of the drive component cover plate 3 through a threaded connection structure. The threaded connection method facilitates the disassembly of the cover plate 3 during maintenance, while ensuring the reliability of the connection in the working state.

[0028] Furthermore, this application also proposes that the driving assembly includes a first collection box 7, a base plate 9, and a support plate 10. The base plate 9 is located below the conveying cylinder 2 and connected to the support plate 10. The support plate 10 is located above the base plate 9. The upper end of the support plate 10 is provided with a first notch for accommodating the first collection box 7. The first collection box 7 with the upper opening is fitted to the inner wall of the first notch. One end of the first collection box 7 is slidably fitted to the support block 6. The base plate 9 is provided with a driving unit for driving the support plate 10 to move closer to or away from the conveying cylinder 2. The upper end of the first collection box 7 can move with the support plate 10 to fit against the outer end of the conveying cylinder 2. The upper end of the first collection box 7 is open.

[0029] Therefore, this technical solution achieves effective collection of ball mill output through the design of a movable first collection component. When material needs to be collected, the drive unit pushes the support plate 10 to move the first collection box 7 upward, so that the upper end of the collection box is tightly fitted with the conveying cylinder 2 to prevent material from scattering. After collection is completed, the drive unit moves the support plate 10 downward, which facilitates the removal, placement and cleaning of the collection box. This structure solves the problem of material scattering caused by traditional open discharge ports, and the detachable design facilitates maintenance and operation.

[0030] Furthermore, this application also proposes that the drive assembly includes a fixed plate 11, a second motor 12, a transmission block 13, and a threaded rod 14. The fixed plate 11 is connected to the end of the base plate 9 away from the support block 6. The fixed plate 11 has a groove at the end facing the support plate 10. The transmission block 13 is slidably disposed in the groove and connected to the support plate 10. The transmission block 13 has a first threaded through hole. The threaded rod 14 is vertically disposed in the groove. One end of the threaded rod 14 is rotatably connected to the inner wall of the groove, and the other end passes through the first threaded through hole and is coaxially connected to the output shaft of the second motor 12. The second motor 12 is connected to the upper end of the fixed plate 11. The first collection box 7 is slidably disposed in contact with the fixed plate 11.

[0031] This technical solution uses a second motor 12 to drive the threaded rod 14 to rotate, which in turn drives the transmission block 13 to move along the slide groove, thereby controlling the lifting and lowering motion of the support plate 10 and the first collection box 7. The threaded transmission method has a self-locking characteristic and can precisely control the stopping position of the collection box.

[0032] Furthermore, this application also proposes that the second collection component includes a second collection box 8, a fixing block 15, and a second bolt 16. The fixing block 15 is located below the discharge port and connected to the support block 6. The fixing block 15 is provided with a first groove, and the second collection box 8, which has an opening at its upper end, rests in the first groove. The fixing block 15 is provided with a second threaded through hole that communicates with the inner wall of the first groove. The second bolt 16 is threaded in the second threaded through hole. The second bolt 16 can be moved to abut against the second collection box 8 and push the second collection box 8 to abut against the inner wall of the first groove.

[0033] In response, this technical solution enables the quick installation and disassembly of the second collection box 8 through an adjustable bolt fixing mechanism, facilitating cleaning and maintenance. The combination of groove positioning and bolt clamping effectively prevents the collection box from shifting during operation, ensuring the reliability of material collection.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
