Technical Field

[0001] The present application relates to the technical field of powder classifiers, and in particular to a V-shaped powder classifier dividing plate. Background Art

[0002] The V-type powder selector is a static grading and dispersing equipment, which is widely used in the field of cement production, and is mainly used as a supporting equipment for roller presses and vertical mills. The working principle of the traditional V-type powder selector is relatively simple. The material enters the shell through the feed port, and collides with the dividing plate under the action of gravity. The material is dispersed in the dispersing area, and hot air is introduced into the powder selection area to complete the drying and grading functions. The coarse particles enter the grinding equipment through the coarse material port, and the fine particles enter the dynamic powder selection equipment through the air outlet for secondary powder selection.

[0003] However, the traditional separator plate is a flat plate with holes and has no protective structure. The separator plate is easily worn by the impact and collision of the material and requires frequent maintenance, which affects the stable operation of the V-type powder classifier.

[0027] like Figure 1 and Figure 2 As shown, the present application provides a V-type powder classifier dividing plate, including a dividing plate body 1, a plurality of mutually parallel first rib plates 2 are fixedly arranged on the top of the dividing plate body 1, a plurality of mutually parallel second rib plates 3 are fixedly arranged between two adjacent first rib plates 2, and the plurality of first rib plates 2 and the second rib plates 3 form a grid structure. Compared with the prior art, the present application improves on the basis of the original dividing plate, and a grid structure is formed on the top of the dividing plate body 1 by the first rib plates 2 and the second rib plates 3. During the initial material division, part of the material will be left in the grid, and the material in the grid is used to contact with the subsequently delivered material to resist the impact, thereby reducing the direct impact force on the dividing plate body 1 and reducing the exposure of the corresponding position of the plate surface of the dividing plate body 1, thereby reducing the degree of wear of the dividing plate body 1, improving durability, reducing maintenance costs, and ensuring the stable operation of the V-type powder classifier.

[0028] like Figure 3 As shown, a first wear-resistant plate 4 is provided in the grid formed by the first rib plate 2 and the second rib plate 3. The first wear-resistant plate 4 is fixed on the dividing plate body 1. The first wear-resistant plate 4 protects the dividing plate body 1 exposed in the grid, thereby further preventing the dividing plate body 1 from being worn.

[0029] like Figure 1 and Figure 3 As shown, the heights of the first rib plate 2 and the second rib plate 3 are consistent, and a second wear-resistant plate 5 is fixedly provided on the top of the first rib plate 2 and the second rib plate 3. The second wear-resistant plate 5 protects the tops of the first rib plate 2 and the second rib plate 3 to prevent the tops of the first rib plate 2 and the second rib plate 3 from being exposed and worn by the impact of materials.

[0030] like Figure 2 As shown, the grid formed by the first rib plate 2 and the second rib plate 3 is square or diamond-shaped. In this embodiment, the grid formed by the first rib plate 2 and the second rib plate 3 is square, and the square grid is more convenient for construction.

[0031] like Figure 2 As shown, a plurality of first rib plates 2 are arranged at equal intervals, so that the distance between two adjacent first rib plates 2 is equal, thereby forming a grid with equal capacity.

[0032] like Figure 2 As shown, a plurality of second ribs 3 are arranged at equal intervals, so that the distance between two adjacent second ribs 3 is equal, thereby forming a grid with equal capacity.

[0033] like Figure 1 and Figure 2 As shown, the separator plate body 1 is provided with four through holes 6 penetrating the first wear-resistant plate 4 of the separator plate body 1. The four through holes 6 are symmetrically arranged in the grids on the front and rear sides respectively. The whole device can be conveniently installed in the V-type powder classifier by using the four through holes 6 in conjunction with bolts and nuts.

[0034] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
