The utility model is related to a kind of dust-extraction unit, especially a kind of dust-extraction unit of grain drying tower.A kind of dust-extraction unit of grain drying tower, including centrifugal dust collector, flow-mixing blower fan and snail cylinder, the air inlet of the flow-mixing blower fan and the exhaust passage of drying tower connect, the air outlet of flow-mixing blower fan is connect with the air inlet duct of snail cylinder, the air inlet of the air outlet connection centrifugal dust collector of the snail cylinder, the top setting rain hat of snail cylinder, the top connection circulation pipe of the centrifugal dust collector, the circulation pipe is connected in the exhaust passage of drying tower, the bottom connection cement output tank of centrifugal dust collector, the bottom connection airlock of the cement output tank.By centrifugal dust collector and the efficiency of dust collection superposition of snail tin, efficiency is improved to 97% or so the efficiency of dust collection of the dust-extraction unit of the utility model, meets the environmental requirement of grain drying tower, the core competitiveness that product is also dried for lift grain lays the first stone.

Description

The dust-extraction unit of grain drying tower
Technical field
The utility model is related to a kind of dust-extraction unit, especially a kind of dust-extraction unit of grain drying tower.
Background technology
The dust-extraction unit of grain drying tower can be divided into following three classes successively according to the height of efficiency of dust collection:Pulse bag removes Dirt device, centrifugal dust collector and gravity settling chamber, wherein, the efficiency of bag filter is up to 99%, but on the too low ground of temperature Fang Rongyi freezes, so should not generally use;And the efficiency of dust collection of gravity settling chamber only has 50% or so, for dust removal requirement height Occasion and do not apply to, so all using centrifugal dust collector on existing grain drying tower, efficiency of dust collection is generally on 80% left side How the right side improves the efficiency of dust collection of centrifugal dust collector in existing dust-extraction unit, and the technology for becoming instantly in the urgent need to address is difficult Topic.
Utility model content
The technical problems to be solved in the utility model is:Based on the above problem, a kind of dedusting dress of grain drying tower is provided It puts.
Technical solution is used by the utility model solves its technical problem:A kind of dust-extraction unit of grain drying tower, Including centrifugal dust collector, flow-mixing blower fan and snail cylinder, the air inlet of the flow-mixing blower fan and the exhaust passage of drying tower connect, mixed flow The air outlet of wind turbine is connect with the air inlet duct of snail cylinder, the air inlet of the air outlet connection centrifugal dust collector of the snail cylinder, snail cylinder Top setting rain hat, the top connection circulation pipe of the centrifugal dust collector, the circulation pipe is connected to going out for drying tower In air duct, the bottom connection cement output tank of centrifugal dust collector, the bottom connection airlock of the cement output tank.
Further, the snail cylinder is included successively from inside to outside outside snail cylinder inner ring, flow deflector, snail cylinder plate inner ring and snail cylinder plate Circle is concentrated with the exhaust gas with granule dust between the snail cylinder plate inner ring and snail cylinder plate outer ring.
The beneficial effects of the utility model are:The efficiency of dust collection of the dust-extraction unit of the utility model by centrifugal dust collector and The efficiency of dust collection superposition of snail cylinder, efficiency are improved to 97% or so, meet the environmental requirement of grain drying tower, also to promote grain The core competitiveness of food drying product lays the first stone.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of snail cylinder in the utility model.
Fig. 3 is the structure diagram in another direction of snail cylinder in the utility model.
In figure:1. centrifugal dust collector, 2. flow-mixing blower fans, 3. snails cylinder, 4. rain caps, 5. circulation pipes, 6. cement output tanks, 7. close wind Device, 31. snails cylinder inner ring, 32. flow deflectors, 33. snails cylinder plate inner ring, 34. snails cylinder plate outer ring.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
As shown in Figure 1, a kind of dust-extraction unit of grain drying tower, including centrifugal dust collector 1, flow-mixing blower fan 2 and snail cylinder 3, the air inlet of flow-mixing blower fan 2 and the exhaust passage of drying tower connect, and the air outlet of flow-mixing blower fan 2 is connect with the air inlet duct of snail cylinder 3, The air inlet of the air outlet connection centrifugal dust collector 1 of snail cylinder 3, the top setting rain hat 4 of snail cylinder 3, centrifugal dust collector 1 Top connects circulation pipe 5, and circulation pipe 5 is connected in the exhaust passage of drying tower, the bottom connection cement output tank 6 of centrifugal dust collector 1, The bottom connection airlock 7 of cement output tank 6.
As shown in figures 2-3, snail cylinder 3 includes snail cylinder inner ring 31, flow deflector 32,33 and of snail cylinder plate inner ring successively from inside to outside Snail cylinder plate outer ring 34 is concentrated with the exhaust gas with granule dust between snail cylinder plate inner ring 33 and snail cylinder plate outer ring 34.
Operation principle:After flow-mixing blower fan 2 washes out the exhaust gas containing dust impurities out of grain drying tower, granule dust exists It can enter under centrifugal force effect along snail 3 walls of cylinder in snail cylinder runner, finally enter in centrifugal dust collector 1;Again by centrifugation Power acts on, and a part of dust is made to settle down along cement output tank 6, is finally excluded from airlock 7, another part dust-laden exhaust gas is through following It is again introduced into the exhaust passage of grain drying tower after endless tube 5, carries out final dusting.Exhaust gas after dedusting can drain into greatly from rain cap 4 In gas.Exhaust gas with granule dust under the action of the centrifugal force, be concentrated mainly on snail cylinder plate inner ring 33 and snail cylinder plate outer ring 34 it Between, the dust-laden exhaust gas between snail cylinder plate inner ring 33 and snail cylinder plate outer ring 34 enters naturally in snail cylinder runner, 33 He of snail cylinder plate inner ring Dust-laden exhaust gas between snail cylinder inner ring 31 is under the action of flow deflector 32, and granule dust can launch back, minute dusts particle meeting By 31 inside of snail cylinder inner ring finally from 4 mouthfuls of discharges of rain cap.
Using the above-mentioned desirable embodiment according to the utility model as enlightenment, pass through above-mentioned description, related work people Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real The content being not limited to novel technical scope on specification, it is necessary to which its technology is determined according to right Property range.
