Description

Technical Field

[0001] The utility model relates to the technical field of powder classifiers, in particular to a novel wear-resistant device for a coarse powder hopper of a raw material mill powder classifier. Background Art

[0002] The traditional powder classifier includes a powder classifier rotor, a powder classifier housing, a coarse powder hopper, etc. The coarse particles separated by the powder classifier pass through the coarse powder hopper (made of steel plate) and are discharged from the coarse powder outlet at the bottom of the coarse powder hopper. Since the coarse particles directly contact the surface of the coarse powder hopper when passing through the coarse powder hopper, the coarse particles will cause certain wear to the coarse powder hopper after long-term use.

[0003] In order to increase the service life of the coarse powder hopper and reduce the wear of the coarse particle materials on the coarse powder hopper, it is necessary to invent a coarse powder hopper wear-resistant device. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a new type of wear-resistant device for the coarse powder hopper of a raw meal mill classifier in view of the deficiencies of the above-mentioned prior art. The new type of wear-resistant device for the coarse powder hopper of the raw meal mill classifier is provided with a circular wear-resistant plate so that a gap is formed between the circular wear-resistant plate and the coarse powder hopper. When the gap is filled with coarse powder material, a material layer is formed on the surface of the coarse powder funnel, and the material layer has a protective effect on the surface of the coarse powder funnel. The coarse powder material behind slides on the material layer without direct contact with the coarse powder funnel, thereby reducing the wear of the coarse particle material on the coarse powder funnel.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0006] A novel wear-resistant device for a coarse powder hopper of a raw material mill powder selector comprises a coarse powder funnel; a plurality of annular wear-resistant plates are fixedly connected to the inner wall of the coarse powder funnel, the annular wear-resistant plates are parallel to the center line of the coarse powder funnel so that a gap is formed between the annular wear-resistant plates and the inner wall of the coarse powder funnel, and the gap is filled with coarse powder material.

[0007] As a further improved technical solution of the utility model, the annular wear-resistant plate is made of steel plate.

[0008] As a further improved technical solution of the utility model, the thickness of the annular wear-resistant plate is 10 mm and the height is 80 mm.

[0009] As a further improved technical solution of the utility model, the diameter of each circle of the circular wear-resistant plates is different, and they are fixedly connected to the inner wall of the coarse powder funnel at even intervals.

[0010] As a further improved technical solution of the utility model, the bottom of the annular wear-resistant plate is welded to the inner wall of the coarse powder hopper.

[0011] The beneficial effects of the utility model are:

[0012] The utility model arranges the circular wear-resistant plate so that a gap is formed between the circular wear-resistant plate and the coarse powder funnel. When the gap is filled with coarse powder material, a material layer is formed on the surface of the coarse powder funnel, and the material layer has a protective effect on the surface of the coarse powder funnel. The coarse powder material behind slides on the material layer without direct contact with the coarse powder funnel, thereby reducing the wear of the coarse particle material on the coarse powder funnel.

[0016] The specific implementation of the utility model is further described below according to the accompanying drawings:

[0017] This embodiment provides a new wear-resistant device for the coarse powder hopper of a raw material mill separator. Figure 1 The raw material mill powder separator includes an upper shell 5, a frame 6, a lower shell 8, a guide blade assembly 7, etc. A fine powder outlet is arranged above the upper shell 5, the bottom of the upper shell 5 is connected to the frame 6, the bottom of the frame 6 is connected to the lower shell 8, the guide blade assembly 7 is located inside the lower shell 8 and connected to the frame 6, a coarse powder hopper 1 is arranged directly below the guide blade assembly 7, the coarse powder hopper 1 is welded to the lower shell 8 through a support frame, and a coarse powder outlet is arranged at the bottom of the coarse powder hopper 1. The novel wear-resistant device for the coarse powder hopper of this embodiment includes a coarse powder hopper 1 and a circular wear-resistant plate 2, such as Figure 1-2 As shown, a plurality of annular wear-resistant plates 2 are fixedly connected to the inner wall of the coarse powder funnel 1, and the annular wear-resistant plates 2 are parallel to the center line of the coarse powder funnel 1 so that a gap 3 is formed between the annular wear-resistant plates 2 and the inner wall surface of the coarse powder funnel 1, as shown in FIG. Figure 3 As shown, the gap 3 is filled with coarse powder material 4. After the coarse powder material 4 fills the gap 3, a material layer is formed in the gap 3.

[0018] In this embodiment, the annular wear-resistant plate 2 is made of steel plate.

[0019] In this embodiment, the annular wear-resistant plate 2 has a thickness of 10 mm and a height of 80 mm.

[0020] In this embodiment, the diameters of the annular wear-resistant plates 2 of each circle are different, and the annular wear-resistant plates 2 are fixedly connected to the inner wall of the coarse powder hopper 1 at even intervals.

When the powder selector is working, the flow direction of fine powder materials is as follows: Figure 1 As shown by the upward arrow in the figure, the flow direction of the coarse powder material is as follows Figure 1 as indicated by the downward arrow in the

[0023] The grinding body of the vertical mill is located below the lower shell 8. The material is fed into the grinding disc in the grinding body, and a material layer of a certain thickness is formed on the grinding disc. The grinding roller is pressurized to generate pressure, and the material is ground to a certain fineness. The grinding disc is rotating, and the material is scattered. There is a certain negative pressure wind inside the grinding body, and the material is sucked away by the wind and taken away from the grinding disc. The sucked away material passes through the powder classifier above the vertical mill. After the powder selection of the powder classifier, the fine powder material that meets the production requirements is taken out of the fine powder outlet of the upper shell 5 of the powder classifier by the negative pressure wind of a certain pressure to form a finished product; the coarse powder material 4 that cannot be taken away by the negative pressure wind of a certain pressure falls into the coarse powder hopper 1 (downward arrow) and is discharged through the coarse powder outlet at the bottom of the coarse powder hopper 1.

[0024] The annular wear-resistant plate 2 of this embodiment is parallel to the center line and forms a certain angle with the inclined coarse powder funnel 1. The coarse powder material 4 flows in the coarse powder funnel 1 and then fills the gap 3 formed by the annular wear-resistant plate 2 and the coarse powder funnel 1. In this way, a material layer is formed on the surface of the coarse powder funnel 1. The coarse powder material 4 behind slides up and down on the material layer without contacting the coarse powder funnel 1, so the coarse powder funnel 1 will not be worn.
