Description

A kind of grain is cleared up the dust pelletizing system of putting in storage

Technical field

The utility model relates to the grain processing field, and particularly a kind of grain is cleared up the dust pelletizing system of putting in storage, and is used for the preliminary processes of grain storage or food processing.

Background technology

At present, be in the processing of raw material with grain, all relate to the production workshop section that the grain cleaning is put in storage mostly, as: the flour mill of grain processing industry, starch factory etc.; The Alcohol Plant of food liquor industry, distillery, brewery and other are the light industry industry of raw material with grain.The grain cleaning is put in storage in the dust pelletizing system; Warehouse mainly adopts vertical silo; Like steel silo and cement concrete storehouse, grain puts in storage and must be beneficial to the storage of grain through primary election cleaning or selected cleaning; Both, also can satisfy the supply of producing needed raw material better for postorder production provides the raw material that meets index request.

The existing grain technological process of production of putting in storage is generally: packed raw grain or vehicle-mounted Bulk Grain → → receive grain bucket (cheated by grain) → → belt conveyer → → bucket elevator → → cleaning equipment → → gauging device → → bucket elevator → → top, storehouse conveyer → → go into silo to store.Just present domestic majority manufacturing line real-world operation in the whole operation flow process, receives this link of grain bucket (cheated by grain) except that raw grain gets into, and other production link can both solve dry linting dirt preferably and raise a difficult problem outward.

At present, at the production link that receives grain bucket (cheated by grain), the traditional dust pelletizing system that adopts mostly is made up of dust collection cover, pulse bag type dust collector and explosion-proof centrifugal blower fan and supporting dust ventilating net.In this dust pelletizing system, because dust collection cover is in suction during airborne dust, a large amount of inrush of airs just can be taken away airborne dust and get into dust pelletizing system, need move down at big air quantity, otherwise treatment effect is relatively poor, causes the increase of system cost and operating cost; In addition, the dust collection cover present position is a condition precedent to reach desirable dust collection effect, needs receiving grain bucket (cheated by grain) mouthful nearer location arrangements, and this directly has influence on into the grain operational space.

Existing follow-on dust pelletizing system; Then pulse bag type dust collector directly is arranged in and receives grain bucket (cheated by grain) upside; The airborne dust air is by receiving to suck in the grain bucket (cheated by grain) in it, and then by replenished by grain bucket (cheated by grain) mouth, the operation treatment effect is better under suitable air quantity for pure air.But also have weak point: 1) pulse bag type dust collector directly is arranged on the feeding mouth that receives grain bucket (cheated by grain), takies part feeding mouth area, and the grain operation is gone in influence.2) dust exhaustor places on the feeding mouth; Must there be corresponding pure air to flow into when in receiving grain bucket (cheated by grain), extracting airborne dust; Position leaked-in air near dust exhaustor is more; Influx more at a distance is few more, and the airborne dust that the grain of pouring into forms almost is evenly to overflow to feeding mouth, must suitably increase ventilation volume for reaching dust removing effects.3) dust of dust exhaustor collection directly is discharged into and receives in the grain bucket (cheated by grain), forms reentrainment of dust, increases dust emission wherein, will increase the dust pelletizing system operating load.

Summary of the invention

To above-mentioned technical matters, the purpose of the utility model is to provide the grain that a kind of pick-up performance is good, over-the-road expense is low, the operational space is big to clear up the dust pelletizing system of putting in storage.

In order to achieve the above object, the utility model adopts following technical scheme to be achieved.

A kind of grain is cleared up the dust pelletizing system of putting in storage; Comprise receiving the grain bucket that the dust exhaustor that is communicated with the feeding mouth that receives the grain bucket is with dust exhaustor top outlet bonded assembly induced draft fan; It is characterized in that; The said feeding mouth of grain bucket that receives is provided with grid, and grid is arranged with the dust suction pipe network, and sweep-up pipe Netcom crosses trunk line and is communicated with the dust exhaustor inlet.

The further characteristics of the utility model are, the lower part outlet of said dust exhaustor and receive to be connected with between the bottom of grain bucket and slip the dirt pipe; Said dust exhaustor is a pulse bag type dust collector.

In the utility model, receive the feeding mouth of grain bucket to be provided with grid, grid is arranged with the dust suction pipe network, and sweep-up pipe Netcom crosses trunk line and is communicated with the dust exhaustor inlet.Like this, dust exhaustor can be away from the feeding mouth that receives the grain bucket to enlarge the operational space; Grid is arranged with the dust suction pipe network; The airborne dust that not only can make the grain poured into form evenly sucks dust pelletizing system when feeding mouth overflows; It is comparatively even that corresponding pure air is gone into through the feeding mouth surface current; As long as guarantee that the air rate of grain inlet center reaches the intensity of kicking up with dust and balances each other, can airborne dust be sent into dust pelletizing system.In addition, the grain of the utility model cleaning dust pelletizing system cost of putting in storage is low, and the dedusting air quantity is little, and over-the-road expense is low, good dedusting effect.

In the utility model, dust exhaustor is a pulse bag type dust collector, and dust laden air is collected the slide dirt pipe that the afterpulse bullet falls into the dust exhaustor bottom through the cloth bag filtration, flows into to receive in the grain bucket (cheated by grain).The pulse bag type dust collector of selecting for use need not be considered to be equipped with airtight discharger, thereby avoids the problem of leaking out, and makes that getting into gas can only be sucked by the dust exhaustor inlet.

In the utility model; The lower part outlet of dust exhaustor and receive to be connected with between the bottom of grain bucket and slip the dirt pipe can be sent into the dust stream that dust exhaustor is collected in the raw grain that receives in the grain bucket (cheated by grain), because the elephant trunk outlet is buried among raw grain; So can play desirable sealing state; Along with raw grain gets into the postorder production process, the dust in the elephant trunk is also taken away thereupon, discharges through the impurity removing equipment of postorder production process.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details.

Fig. 1 clears up the structural representation of the dust pelletizing system of putting in storage for a kind of grain of the utility model;
