Anti-blockage mesh screen for screening machine

Abstract

The invention discloses an anti-blockage mesh screen for a screening machine. The anti-blockage mesh screen for a screening machine comprises a screening frame. The top of the screening frame is connected with a screening net frame through vibration springs. A screening net is welded to the inner side of the screening net frame. First roll shafts and second roll shafts are equidistantly and rotatably connected to the inner side of the screening frame, wherein the first roll shafts and the second roll shafts are equidistantly and alternately distributed; one end of each first roll shaft is rotatably connected with a rotatable connecting shaft extending to the outer side of the screening frame, and one end of each second roll shaft is rotatably connected with a rotatable connecting shaft extending to the outer side of the screening frame. A rotating motor is fixed to the bottom of one end of the screening frame. The rotating motor is in transmission connection with a rotary fluted disk through a coupling. The rotary fluted disk is rotatably connected with the rotatable connecting shafts located at one ends of the first roll shaft and the second roll shaft through a transmission chain. According to the anti-blockage mesh screen, the first roll shafts are rotatably connected; the first roll shafts rotate and can turn over materials through turnover frames, so that the materials arescreened more safely, and the practicality of the screening net is enhanced.

Description

technical field [0001] The invention relates to the technical field of screening machines, in particular to an anti-clogging screen used in screening machines. Background technique [0002] Screening is the process of using a sieve to make the fine-grained materials smaller than the sieve holes pass through the sieve surface, while the coarse-grained materials larger than the sieve holes stay on the sieve surface, thereby completing the process of separating coarse and fine materials. The separation process can be regarded as composed of two stages: material stratification and fine particle sieving. Material stratification is the condition to complete the separation, fine particles suitable for sieving is the purpose of separation, and screening is the process of dividing mixed waste with different particle sizes into two or more groups of particles by using one or more sieve surfaces. Screening often has two operations, wet selection and dry selection. Dry selection is oft...

AI Technical Summary

Problems solved by technology

[0003] The screen structure of the traditional screening machine is relatively simple, and the lack of measures to turn over the materials on the screen results in insufficient screening. At the same time, the lack of cleaning measures for screen blockage affects the efficiency of screening.
