Problems solved by technology

In the above technical solution, the material first falls on the spreading plate and then hits the baffle plate and spreads to the surroundings. However, the material itself is prone to agglomeration, and it is difficult to fully break up the lumpy material after only one impact. The efficiency and cleaning rate of the separation will be affected when the bulk materials that are fully broken up enter the sorting room

Embodiment 1

[0049] A sorting grid 21 of this embodiment. The sorting grid 21 includes a plurality of inverted frustum-shaped outer grid plates 212, a plurality of forward frustum-shaped inner grid plates 211, and a plurality of grid plates 213. The selection grid 21, the outer grid plate 212 and the inner grid plate 211 are coaxially sleeved along the central axis of the sorting grid 21, and a plurality of the outer grid plates 212 and the inner grid plates 211 are arranged in a radial direction. The grid plates 213 are connected from top to bottom to form a whole and form an air duct for air to pass through and a dispersing and sorting channel for materials to fall step by step.

[0050] Such as figure 1 , image 3 As shown, the inner ring of the sorting grid 21 is the inner grid plate 211 arranged step by step along the axis, and the outer ring is the outer grid plate 212 arranged step by step along the axis. The inner grid plate 211 and the outer grid plate 212 pass through the partition ...

Embodiment 2

[0056] A sorting grid 21, such as figure 1 , figure 2 , image 3 As shown, the sorting grid 21 includes at least one inner grid plate 211 that is a rounded truncated platform with a small top and a large bottom, at least one outer grid plate 212 that is a rounded truncated platform with a large top and a small bottom, and at least one is connected to the inner grid at the same time. 211 and the grid plate 213 of the outer grid plate 212, the inner grid plate 211 located in the inner ring and the outer grid plate 212 located in the outer ring are coaxially arranged along the center axis of the sorting grid 21 and connected into a whole by the grid plate 213, At the same time, the inner grid plate 211 and the outer grid plate 212, which are both thin-walled pieces, form an air channel for the gas to quickly pass through and a sorting channel for the material to drop and disperse step by step.

[0057] The number of the inner grid plate 211 and the outer grid plate 212 is multiple (...

Embodiment 3

[0063] Such as Figure 4 to Figure 8 As shown, a powder classifier using a sorting grid 21 for sorting includes a shell 1 welded with a fixed foundation 001 on the outside and a material sorting cavity set inside, and powder sorting installed on the shell 1 respectively Mechanism, feeding mechanism 3, discharging mechanism; the housing 1 is provided with an air inlet 11, an air outlet 12, a material inlet 13, and a material outlet communicating the inside and outside of the housing 1, and the air inlet 11 is located below the air outlet 12 , The feeding device is connected to the feeding port 13 and the feeding end of the powder selecting mechanism, while the discharging device is connected to the discharging port and the discharging end of the powder selecting mechanism. The powder selecting mechanism includes a sorting device for one-stage sorting. The grid 21 and the feeding end of the sorting grid 21 at the top are connected with the feeding device. Such as Figure 5 As sho...

Abstract

The invention discloses a sorting grid. The sorting grid comprises multiple inverted frustum type outer grid plates, multiple forward frustum type inner grid plates, and a sorting grid consisting of multiple grid plates; the outer grid plates and the inner grid plates are coaxially sleeved along the center axis of the sorting grid; and multiple outer and inner grid plates inserted one by one are connected as a whole from top to bottom through the grid plates arranged in the radial direction to form wind ways for enabling wind to pass through and scattering and sorting channels for enabling materials to fall step by step. The invention further discloses a powder selecting machine for sorting by the sorting grid; and the powder selecting machine includes a shell provided with a material sorting cavity inside, a sorting grid mounted in the material sorting cavity, a feed mechanism and a discharge mechanism. The sorting grid is used for enabling the materials to collide by multiple times for full scattering in the natural falling process under the effect of self weight in limited space; and a sorting machine once sorts the materials in the gradual scattering process to effectively improve the sorting efficiency and the sorting rate.

Description

Technical field [0001] The invention relates to the fields of building materials, metallurgy, and chemical powders. Specifically, it is a powder separator that uses a sorting grid for sorting. Background technique [0002] In the processing of building materials, metallurgy, and chemical industry, large pieces of materials are often ground and then sorted by a powder separator to process fine powders that meet the material standards into finished products, and those that do not meet the material standards The coarse material is again ground and sorted, but after the existing powder classifier is sprinkled through the sprinkler, the material enters the powder selection room for only one sorting, the coarse powder is not completely separated, and a large amount of fine powder and coarse powder are mixed in Enter the lower cone together and return to the mill for regrind. The mixing of fine powder and coarse powder into the mill for grinding will aggravate the repetitive work of the...
