Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] like figure 1 As shown in the figure, the anti-jamming grate sliding screen of the present invention is the sieve plate 1, the two sides of the sieve plate 1 are respectively provided with fixing ears 4, and the sieve plate 1 is fixed on the external fixture through the fixing ears 4 on both sides; The plate 1 is inclined to the horizontal plane along the sliding direction of the material, and the inclined angle is 15°~60°. By adjusting the inclined angle of the screen plate 1, the passing rate of the material can be increased or decreased. The larger the inclined angle is, the screening passes The rate is low, on the contrary, the smaller the angle of inclination is, the larger the screening pass rate is. One end of the sieve plate 1 is located below the feed port 12, and the other end is the discharge port 5; the sieve plate 1 is provided with a plu...

Abstract

The invention relates to material screening equipment, in particular to anti-jamming grate-bar slide screen which is used for separating a coarse material from a fine material. The slide screen comprises a screen plate, wherein the screen plate is mounted on an external fixture and inclined to the horizontal plane in a material slipping direction; one end of the screen plate is positioned below the feed opening; discharge openings are formed in the other end of the screen plate; a plurality of grooves with are formed in the screen plate in the material slipping direction, one end of each groove is open; grate bars are formed between adjacent grooves; the open ends of the grooves are the discharge openings of the screen plate; the widths of the shadows, on the horizontal plane, of the grooves gradually increase in the material slipping direction; the widths, on the cross sections of the screen plate in the thickness direction of the screen plate, of the grooves gradually increase from the top down; the ends, below the feed opening, of the grate bars are wider than those, at the discharge openings, of the grate bars; and the upper parts of the grate bars are wider than the lower parts of the grate bars in the thickness direction of the grate bars. The slide screen is free from a material-jamming phenomenon, has the advantages of great load-bearing capacity, abrasion resistance, simplicity in maintenance, space saving, no electricity consumption and high use value, can feed materials in categories, and realizes the close-range combination of the equipment.

Description

technical field [0001] The invention relates to material screening equipment, in particular to an anti-jamming grate bar sliding screen, which is used for screening materials with coarse materials and fine materials. Background technique [0002] The existing screening equipment mainly adopts the method of vibrating screen. The downward sliding and screening of materials mainly rely on the strong vibration of the vibration source, which promotes the separation of coarse and fine particles of the screened materials; such as China Construction Industry Publishing House The company published in November 1994, the ISBN7-80090-342-7 / TH·12, "Crushing Engineering and Equipment" Chapter 4, Chapter 2, and published on May 2, 2012, the public number is 102430517A, The application number is 201110410605.4 of the Chinese invention patent "A vibrating sliding screen". The sieves used in the above-mentioned screening equipment are vibrating sieves of different shapes or structures and eq...
