Working method of vibratory screening equipment with intermittent feeding function for granular material

Abstract

To achieve the purpose, the invention provides a working method of vibratory screening equipment with an intermittent feeding function for a granular material. The vibratory screening equipment comprises an enclosure, wherein an annular support plate is arranged in the enclosure; a sieve is fixedly connected to the bottom of the annular support plate and connected with the inner bottom of the enclosure through a sieve vibrating device; a material disturbance device is arranged at the upper side of the sieve and comprises a first rotating shaft; and the top end of the first rotating shaft penetrates the enclosure and extends upwards and is fixedly connected to an output shaft of a first motor. The following beneficial effects are achieved: first, the first rotating shaft drives a disturbance bulge to rotate through a coordinating rod, and the disturbance bulge disturbs the material on the sieve to guarantee normal proceeding of sieving, so that the problem of material accumulation is effectively solved; and second, a first spring arranged here can enable the rotating coordinating rod to move up and down so as to adapt to the sieve which moves up and down.

Description

technical field [0001] The invention relates to the technical field of screening, in particular to a working method of vibrating screening equipment for granular materials with intermittent feeding function. 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 for separation, and fine particle sieving is the purpose of separation. [0003] In the industrial production process, granular materials often exist, and granular materials need to be screened to obtain the required particle size; those that do not meet the particle size requirements need to...
