Description

Screening plant is used in production of granule zinc stearate Technical Field The invention relates to the technical field of granular zinc stearate production, in particular to a screening device for granular zinc stearate production. Background Zinc stearate is an organic substance, has a chemical formula of C 36H70O4 Zn, is a white powder, and is insoluble in water. Is mainly used as a lubricant and a release agent for styrene resin, phenolic resin and amino resin. Meanwhile, the rubber also has the functions of a vulcanization active agent and a softening agent. The specification of the granular zinc stearate is not easy to control in the production process, the produced zinc stearate particles are doped, and because the zinc stearate has certain requirements on the particle diameter in the use process, although the requirements are not very strict, the smaller-diameter particles can not meet the use specification, and if the zinc stearate particles are not screened, the zinc stearate selling quality can be reduced by the uneven-specification particles. In general, screening is often performed using a screen, but screening efficiency is not improved if a large amount of zinc stearate is screened. Disclosure of Invention The invention discloses a screening device for granular zinc stearate production, which aims to solve the technical problem that screening efficiency cannot be improved if a large amount of zinc stearate is screened in a general screening mode by using a screen. In order to achieve the above purpose, the present invention adopts the following technical scheme: the screening device for the production of the granular zinc stearate comprises two screening mechanisms, wherein the two screening mechanisms are connected through a driving mechanism, the inner walls of the top ends of the two screening mechanisms are simultaneously connected with a three-way conveying pipe, the three-way conveying pipe comprises an input port and two output ports, electromagnetic valves are respectively arranged on the two output ports, and the outer walls of one sides of the two screening mechanisms are simultaneously connected with a supporting cover; Each screening mechanism comprises a screening box body, square holes are respectively penetrated through the screening box bodies, one ends of the square holes are tightly connected with fans, the output ends of the fans face into the screening box bodies, the other ends of the square holes are tightly connected with valves, and one sides of the valves are sequentially provided with a large particle collecting box and a small particle collecting box; Every swing joint has the tray in the screening box, and the outer wall laminating of tray in the inner wall of screening box, the inner wall of screening box is located tray below fixedly connected with baffle, the bottom outer wall symmetry fixedly connected with of tray a plurality of spacing inserted bars, and a plurality of spacing inserted bars pass the baffle simultaneously, the bottom outer wall of tray is connected with the second spring simultaneously with the top outer wall of baffle, and the bottom outer wall of two trays links to each other with actuating mechanism simultaneously. Through being provided with screening mechanism, in the screening mechanism, the material is carried in to the screening box through tee bend conveying pipeline, rethread actuating mechanism drives the tray drop, afterwards drive the granule zinc stearate in the tray under the elastic action of second spring and bounce, this step is repeated twice, as first screening, in the process of bouncing, heavier granule can drop earlier lighter granule, first screening back, the granule that mixes together can be in the screening box and be located the lower floor in most, granule is located the state on upper strata in most, the valve is opened again, spill square hole, the synchronous repeated step of bouncing again, and open the fan, the granule that pops up is more regular than first bouncing, big granule after the layering is when receiving equiforce bouncing, basically be located lower position when avoiding blowing, cause blocking to the granule because under equal wind, heavier granule distance can be less granule from this, big granule gets into big granule collecting box thereupon, the granule is got into and is accomplished screening in the granule collecting box, under this screening structure, under satisfying the screening demand of granule zinc stearate, also can effectively improve screening efficiency in batches simultaneously. In a preferred scheme, actuating mechanism includes two ratchets, and the latch setting opposite direction of two ratchets, links to each other through the pivot between two ratchets, and the both ends of pivot are connected with the bearing frame respectively, are provided with the empty slot on every ratchet respectively, two the bottom of bearing frame is fixedly connected with chassis simul
