The self-emptying feed bin
Technical field
The utility model relates to a kind of Storage Silo that transmits powder or solid particle material that is mainly used in.
Background technology
Further process for operations such as next pulverizing, packing in the chemical field, and temporarily store and transmit the feed bin of powder or solid particle material, form by the taper feed bin body 1 shown in Figure 2 and the airtight discharger 2 of lower end discharging.Material enters feed bin by inlet point, is discharged by airtight discharger.Upper end cover middle part at feed bin is fixedly connected with a reductor 3, and reductor 3 connects an impeller paddle stirrer 4 that always gos deep into the feed bin funnel bottom.In the discharging process, because powder or solid particle material are deposited in the taper feed bin body, under gravity, each powder or particulate matter bear against together mutually, and material can be built bridge.When discharging, the material at close discharging opening place, bottom can fall naturally and discharge.And the stone arch bridge effect will appear in the material far away slightly apart from bottom discharging opening place, stops the top material to fall to discharging opening, forms the top solid accumulation and the arch formation of bottom spaciousness.Behind the bridge formation, be stored in the powder or the solid particle material on feed bin top, though under the stirring of the paddle stirrer 4 that rotates, still can not drop to the feed bin discharging opening or enter airtight discharger.At the material of the feed bin middle and upper part discharging opening of not arriving, caused material can not continue to discharge like this.This material obstruction just occurred.Because paddle stirrer can not be eliminated the arch formation of material fully in rotation, the phenomenon that material stops up discharging opening takes place often, cause manufacturing line production to be interrupted.The impeller of airtight discharger in addition in rotary course, is the outlet that the chamber that will fill material between the first half blade rotates to the bottom, and material is discharged.After a chamber discharging of having filled material is finished, and another adjacent chamber of having filled material does not also forward discharging opening to, and few for a long time pulsation phenomenon when airtight discharger discharging is occurred is given the equipment of subsequent processing, bring as comminutor etc. either large or small, fluctuating load that can not smooth working.This phenomenon is even more serious when the rotating speed of airtight discharger transfers to slow speed of revolution.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, provides a kind of material that can not take place to stop up the continuous pulsation-free self-emptying of mass transport feed bin.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of self-emptying feed bin that the utility model provides, having one stores the taper feed bin body of material and stretches into the interior mixer that is connected the upper end reductor of feed bin funnel, it is characterized in that, driven and the mixer that rotates in above-mentioned feed bin is a fram agitator by described reductor, the discharging mechanism that communicates with feed bin funnel bottom is a spiral discharging device that has frequency converter.
The utility model has following beneficial effect than prior art.
Because fram agitator can force the powder in the feed bin in rotary course or the bridge formation basis of solid particle material---the material near the taper inner tube wall constantly moves, and destroys the formation on material bridge formation basis.Make the material that is positioned at feed bin top, can under effect, automatically fall to the discharging opening of feed bin, enter in the spiral discharging device, material is sent into subsequent processing equipment smoothly, do not produce material and stop up at gravity.Because the material that adopts the spiral discharging device helical feed to go out operates steadily continuously, the no pulse fluctuation has guaranteed the stability that the subsequent processing equipment work is loaded.Fundamentally eliminated the airtight discharger transmission of prior art fluctuation workload, few for a long time pulsation wave phenomenon during discharging.Solved material bridge formation obstruction in the feed bin, the uneven problem of discharging.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing
In Fig. 1, have a taper feed bin body 1 and an installation that stores material and connect firmly moral reductor 3 on the big end end cap of warehouse, and the inlet point on the end cap has kept the prior art constructions present situation.The mixer that wherein stretches in the feed bin funnel and connect the upper end reductor is a fram agitator.Drive and the mixer that rotates in above-mentioned feed bin is a fram agitator by described reductor.This fram agitator by the center shaft that connects the reductor main shaft and radially the five equilibrium vertical plane frame that connects firmly described center shaft form.The plane frame is parallel from top to bottom along the inner cone cylinder die cavity of taper feed bin body 1, and keeps at a certain distance away.The discharging mechanism that communicates with feed bin funnel bottom is a spiral discharging device 5 that has frequency converter.Spiral discharging device 5 is assemblied in the horizontal discharging cylindrical shell and with the electric machine main shaft of being furnished with frequency converter and links to each other.
During use, powder or solid particle material enter taper feed bin body 1 by inlet point, the fram agitator 6 that reductor 3 drives, and material is stirred in rotation in feed bin.Material by self gravitation, automatically falls into feed bin bottom discharging opening under the rotation of frame stirring 6, enter spiral discharging device 5 spirals and discharge.The discharging speed of spiral discharging device is regulated by the frequency converter that connects motor and is changed, and makes it discharge feed bin reposefully automatically, continuously, is transported to down processing apparatus, or comminutor.
