Description

Technical Field

[0001] The utility model relates to the technical field of cement vertical mills, in particular to a cement raw material vertical mill device. Background Art

[0002] Limestone raw materials, clay raw materials and a small amount of correction raw materials (sometimes mineralizers, crystal seeds, etc. are added, and coal is also added during vertical kiln production) are mixed in proportion and ground to a certain fineness, which is called cement raw material.

[0003] At present, there is an existing raw meal vertical mill device with a stable material layer (such as patent number: CN219442007U), which discloses a raw meal vertical mill device with a stable material layer. By setting a central discharge barrel, the material is directly guided to the center of the grinding disc, avoiding the problem of uneven material layer caused by the material falling directly to the edge of the grinding disc; by setting a guide cone and a partition plate, it is more conducive to the uniform dispersion of the material, which is conducive to the formation of a stable material layer on the grinding disc and the stable operation of the vertical mill. By setting an annular material retaining ring, the material will form a certain accumulation in the gap between the annular material retaining ring and the center cover plate, and the connecting bolts will be covered by the accumulated material, that is, a material dead zone is formed, which can prevent the flowing material from causing wear on the connecting bolts.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following problems: the discharge end of the feeding chute was connected to the central discharge barrel, and the material entered the interior of the central discharge barrel from the feeding chute. When the material flowed from the feeding chute into the central discharge barrel, when the material passed through the bend of the feeding chute, if the humidity of the material was too high, the material would stick to the bend, which could easily cause the feeding chute to be blocked, affecting the working efficiency of the device.

The striking plate 10 is located between the two springs 9. By setting the striking plate 10 and cooperating with the spring 9, when the device is working, the material enters from the feed pipe 2, and the motor 3 starts to drive the gear 4 to rotate. When the gear 4 is engaged with the rack 6, the gear 4 drives the rack 6 to move. At this time, the rack 6 pushes the mounting plate 7, and the spring 9 is stretched. When the gear 4 is not engaged with the rack 6, the mounting plate 7 returns to its original position under the action of the spring 9. At this time, the striking plate 10 hits the surface of the feed pipe 2. As the motor 3 drives the gear 4 to rotate continuously, the gear 4 and the rack 6 form an intermittent motion mechanism.

[0026] Both ends of the mounting plate 7 are provided with mounting grooves 11, and the interior of each mounting groove 11 is clamped with a mounting block 12. The spring 9 is fixedly connected to the outside of the mounting block 12, which is convenient for the disassembly and assembly of one end of the spring 9. The upper surface of the mounting plate 7 is provided with an insert plate 13, and both ends of the insert plate 13 are movable through the mounting plate 7 to the interior of the mounting groove 11. A slot 14 is provided on the outside of each mounting block 12.

[0028] Working principle:

[0029] The first step is to place the spring 9 into the space formed by the side of the mounting plate 7 and the feed tube 2. At this time, slide the connecting plate 19 to connect the outside of the screw 17. At this time, insert the mounting plate 7 into the inside of the mounting groove 11. At this time, thread the nut on the outside of the screw 17. At this time, slide the insert plate 13 downward into the slot 14. At this time, the nut 16 is threaded on the outside of the threaded rod 15 and fits with the upper surface of the insert plate 13. At this time, the insert plate 13 is fixed, and the installation of the spring 9 is completed.

[0030] In the second step, when the device is working, the material enters from the feed pipe 2, and the motor 3 starts to drive the gear 4 to rotate. When the gear 4 is engaged with the rack 6, the gear 4 drives the rack 6 to move. At this time, the rack 6 pushes the mounting plate 7, and the spring 9 is stretched. When the gear 4 is not engaged with the rack 6, the mounting plate 7 returns to its original position under the action of the spring 9. At this time, the striking plate 10 hits the surface of the feed pipe 2. As the motor 3 drives the gear 4 to rotate continuously, the gear 4 and the rack 6 form an intermittent motion mechanism. At this time, the striking plate 10 can intermittently hit the outside of the feed pipe 2.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
