Description

Technical Field

[0001] This utility model relates to the field of wet mill unloading technology, and in particular to a tiltable wet mill unloading device. Background Technology

[0002] Tilting wet mills are mainly used for wet grinding of cemented carbide materials, and can also be used for grinding metal powders and non-metal powders. The advantage of tilting wet mills is that the grinding cylinder can be tilted upwards for loading and downwards for unloading, while maintaining a horizontal state during operation, which is quite convenient.

[0003] Existing tilting wet mills, during unloading, often fail to remove large particles from the slurry within the grinding drum, as these particles may be present. This is because the slurry is typically poured out directly without any screening function. Therefore, this invention proposes a tilting wet mill unloading device. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a tilting wet mill unloading device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tilting wet mill unloading device, comprising:

[0007] wet grinding mill body;

[0008] A wet grinding cylinder is rotatably mounted on the wet grinding mill body, and a geared motor for driving the wet grinding cylinder to rotate is fixedly mounted on the wet grinding mill body;

[0009] The unloading hopper is fixedly installed on the wet mill body by multiple brackets, and the unloading hopper is located below the opening of the wet mill cylinder. The lower opening of the unloading hopper is fixedly connected to the unloading pipe.

[0010] The self-cleaning filter assembly includes a filter plate movably installed in the discharge hopper, a rotating shaft movably passing through the top of the filter plate, a drive motor for driving the rotating shaft to rotate is fixedly installed on the wet mill body, a hexagonal shaft is slidably inserted into the top of the rotating shaft, and multiple scrapers are circumferentially fixedly installed on the surface of the hexagonal shaft, and the scrapers slide against the surface of the filter plate.

[0011] Preferably, a positioning block is fixedly installed on the side of the filter plate, and a positioning groove is provided on the top of the unloading hopper, and the positioning groove is slidably inserted into or separated from the positioning block.

[0012] Preferably, an annular baffle is fixedly installed on the top of the filter plate, and two door-shaped handles are symmetrically fixedly installed on the top of the annular baffle.

[0013] Preferably, a right-angle frame is fixedly installed on the wet grinding mill body, and a touch switch is fixedly installed on the inner top of the right-angle frame. A stop lever is provided below the touch switch, and the stop lever is fixedly installed at the end of the wet grinding cylinder.

[0014] Preferably, the top of the rotating shaft is provided with a hexagonal groove, and the hexagonal groove is inserted into or separated from the hexagonal shaft.

[0015] Compared with existing technologies, the advantages of the tilting wet mill unloading device provided by this utility model are as follows:

[0016] 1. By intercepting larger particles through the filter plate, it can effectively filter out any larger particles that may be flowing out with the slurry. At the same time, the filter plate can be disassembled, which makes it convenient for staff to clean it regularly.

[0017] 2. When the wet grinding cylinder tilts downward to unload the material, the shift lever will touch the touch switch. At this time, the drive motor will automatically start and control each scraper to scrape the particles and slurry on the filter plate through the rotating shaft. This will speed up the flow rate of the slurry on the filter plate and effectively prevent the filter plate from clogging. Attached Figure Description

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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1 to 3 A tilting wet mill unloading device, comprising:

[0024] The wet mill body 1; the wet mill cylinder 2, which is rotatably mounted on the wet mill body 1, and a geared motor 3 for driving the wet mill cylinder 2 to rotate is fixedly mounted on the wet mill body 1; the unloading hopper 5, which is fixedly mounted on the wet mill body 1 through multiple brackets 4, and the unloading hopper 5 is placed below the cylinder opening of the wet mill cylinder 2, and the lower cylinder opening of the unloading hopper 5 is fixedly connected to the unloading pipe 6.

[0025] The self-cleaning filter assembly includes a filter plate 7 movably installed inside the discharge hopper 5. A positioning block 11 is fixedly installed on the side of the filter plate 7. A positioning groove is opened on the top of the discharge hopper 5, and the positioning groove and the positioning block 11 are slidably inserted or separated. By using the insertion and cooperation between the positioning block 11 on the filter plate 7 and the positioning groove on the discharge hopper 5, the filter plate 7 is limited, effectively preventing the filter plate 7 from rotating.

[0026] A rotating shaft 17 is movably inserted through the top of the filter plate 7. A drive motor 8 for driving the rotating shaft 17 to rotate is fixedly installed on the wet mill body 1. A hexagonal shaft 9 is slidably inserted into the top of the rotating shaft 17. Multiple scrapers 10 are fixedly installed circumferentially on the surface of the hexagonal shaft 9, and the scrapers 10 slide against the surface of the filter plate 7. A hexagonal groove is opened on the top of the rotating shaft 17, and the hexagonal groove is inserted into or separated from the hexagonal shaft 9. Through the insertion and engagement of the hexagonal shaft 9 and the hexagonal groove on the rotating shaft 17, it is convenient to directly remove the hexagonal shaft 9 and the rotating shaft 17 from the filter plate 7, and it is also convenient to remove the filter plate 7 from the rotating shaft 17 for cleaning.

[0027] Furthermore, an annular baffle 12 is fixedly installed on the top of the filter plate 7. Two door-shaped handles 13 are symmetrically fixedly installed on the top of the annular baffle 12. The staff can directly remove the filter plate 7 through the door-shaped handles 13. The annular baffle 12 can block the particles on the filter plate 7 when it is removed to prevent the particles from tilting and slipping.

[0028] Furthermore, a right-angle frame 14 is fixedly installed on the wet grinding mill body 1, and a touch switch 16 is fixedly installed on the inner top of the right-angle frame 14. A stop lever 15 is provided below the touch switch 16, and the stop lever 15 is fixedly installed at the end of the wet grinding cylinder 2. When the wet grinding cylinder 2 tilts downward to unload material, the stop lever 15 will touch the touch switch 16. At this time, the drive motor 8 will automatically start and control each scraper 10 to hang the particles and slurry on the filter plate 7 through the rotating shaft 17. This will accelerate the flow rate of the slurry on the filter plate 7 and effectively prevent the filter plate 7 from clogging.

[0029] The working principle of this utility model is as follows:

[0030] In use, the cylinder opening of the wet grinding cylinder 2 is tilted upward by the reduction motor 3, and then the slurry is poured into the wet grinding cylinder 2. Then, the wet grinding cylinder 2 is rotated to a horizontal position by the reduction motor 3 for operation. Finally, after the operation is completed, the cylinder opening of the wet grinding cylinder 2 is tilted downward by the reduction motor 3, and the slurry after operation is poured into the discharge hopper 5.

[0031] The slurry poured into the discharge hopper 5 is filtered by the filter plate 7, which can intercept larger particles on its surface, while the fine slurry flows out through the suction pipe 6.

[0032] At the same time, when the wet grinding cylinder 2 tilts downward to unload the material, the lever 15 will touch the touch switch 16. At this time, the drive motor 8 will automatically start and control each scraper 10 to scrape the particles and slurry on the filter plate 7 through the rotating shaft 17. This will speed up the flow rate of the slurry on the filter plate 7 and effectively prevent the filter plate 7 from clogging.

[0033] Finally, staff can periodically remove the filter plate 7 and scraper 10 directly through the two door handles 13 for cleaning.

[0034] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
