Problems solved by technology
[0002] The size of the particles in the sieve is often different, there are large and small, and most of the time it is necessary to screen out the particles of similar size separately. The usual method is to select the smaller particles first by using a sieve with a smaller aperture. Then change to a screen with a larger aperture to screen out larger particles, which makes the screening process very troublesome and greatly increases the labor intensity; and in the screening process, some particles with a similar aperture to the screen are easy to block the screen , making it difficult to screen

Embodiment Construction
[0011] Such as figure 1 As shown, an anti-blocking cylindrical grading screen includes two cylindrical frames 1 arranged parallel to each other and a screen 2 fixed between the two cylindrical frames 1. In the screen 2 between the two cylindrical frames 1 There are two ribs 3, and each rib 3 is set parallel to the cylindrical frame 1. The front cylindrical frame 1 and the adjacent ribs 3 form a primary screen area 4, and the rear cylindrical frame 1 The third-level screen area 6 is formed between the 3 adjacent ribs, and the second-level screen area 5 is formed between the two ribs. The screen cloth 2 on each level of screen area is interwoven with elastic screen bars 7 such as steel wire bars, rubber bars or polyurethane bars.

The invention relates to an anti-blocking cylindrical classifying screen which comprises two parallel cylindrical frames and a screen fixed between the two cylindrical frames and is characterized in that two rib plates are arranged in the screw between the two cylindrical frames; each rib plate is parallel to the cylindrical frames; a primary screen region is formed between the cylindrical frame at the front end and the adjacent rib plate; a tertiary screen region is formed between the cylindrical frame at the rear end and the adjacent rib plate; a secondary screen region is formed between the two rib plates; the screen apertures on the primary, secondary and tertiary screen regions are gradually increased; and the screen on each screen region is formed in a mode that elastic screen bars are interwoven. Due to the adoption of the anti-blocking cylindrical classifying screen, screening can be carried out in a classified mode, the screen can be prevented from being blocked and the working efficiency is improved.
Description
technical field [0001] The invention relates to a classifying screen, in particular to an anti-blocking cylindrical classifying screen. Background technique [0002] The size of the particles in the sieve is often different, there are large and small, and most of the time it is necessary to screen out the particles of similar size separately. The usual method is to select the smaller particles first by using a sieve with a smaller aperture. Then change to a screen with a larger aperture to screen out larger particles, which is very troublesome and labor-intensive; and during the screening process, some particles with a similar aperture to the screen are likely to block the screen , which brings difficulties to the screening work. Therefore, a new technical solution is needed to solve the above technical problems. Contents of the invention [0003] The object of the present invention is to provide an anti-blocking cylindrical grading sieve, the sieve has high working effi...
