Abstract

The utility model provides a novel pneumatic conveying device which comprises a high pressure fan, a quantified output material bin, a vacuum generator, a fan pipe, a large material bin, a dust remover, a material bin valve and a bucket elevator. After materials are smashed, under the action of the high pressure fan and the vacuum generator, wind power serves as motive power, the materials are conveyed to the large material bin through the wind pipe and conveyed to a carbonized furnace through the material bin valve and the bucket elevator, and carbonization treatment is carried out. According to characters of materials like crop stalks, the high pressure fan is utilized for serving as the motive power of pneumatic conveying, a series of complex complete devices such as screw compressors, gasholders which are generally used at present are replaced, cost can be saved, and environmental pollution can be avoided due to an integral conveying system.

Description

A kind of Novel pneumatic feedway

Technical field

Pneumatic conveyer of the present utility model belongs to transportation art, is particularly useful for the remote conveying of biomass straw.

Technical background

Along with the rapidly exploitation of technology energy oil, coal, natural gas energy resource, its resource reduces increasingly, has formed global energy shock, and has caused the gross pollution of air environment, and the living beings novel energy produces by sun photosynthesis every year, and is never exhausted.Biomass energy is all being studied by the American-European state that waits in the world at present, China has also strengthened the exploitation dynamics of biomass energy, the exploitation enterprise of biomass energy is surging forward, but in the living beings technological process of production, in the course of conveying of the various links of design biomass straw, the overwhelming majority all adopts belt conveyer, not only floor area is large, and cost is high, also can cause and shed phenomenon, according to circumstances, we have developed economical and have been applicable to remote Pneumatic conveyer.

The utility model content

The utility model has designed a kind of novel Pneumatic conveyer in order to solve the materials such as remote conveying stalk.

The utility model adopts a kind of Pneumatic conveyer, it is characterized in that, this device comprises high pressure positive blower, quantitatively exports feed bin, vacuum generator, airduct, big material bin, dust exhaustor, feed bin valve and bucket elevator; Under the effect of high pressure positive blower and vacuum generator, as power material is transported to big material bin by airduct with wind-force behind the crushing material, by feed bin valve and bucket elevator material is transported to retort again and carries out carbonization treatment.

Further, dust enters in the dust exhaustor through the quantitative exhaust outlet of output feed bin, and the filter bag by dust exhaustor falls dust-filtering.

Further, adopt the design of ball-and-socket type joint at the turning of airduct.

Further, described vacuum generator adopts the design of cover tubule in the extra heavy pipe, the air outlet of the straight-through high pressure positive blower in tubule rear end, and the tubule front end is apart from the 150mm of inlet point place of extra heavy pipe.

Further, described material is stalk.

Further, described device is by satisfying vacuum generator to the demand of air quantity to the control of high pressure positive blower shutter.

The beneficial effects of the utility model are:

1. according to the characteristic of stalk: density is little, and easily wind send, and wind-force requires not too large.

2. the power that send as wind with high pressure positive blower replaces now the generally screw air compressor of use, the complete equipment of the series of complexes such as storage tank, and with a large amount of equipment funds.

3. vacuum generator adopts the method for cover tubule in the extra heavy pipe, the tubule rear end leads directly to the high pressure positive blower air outlet, reduce windage, before can have an about 150mm in extra heavy pipe inlet point the place ahead, when blower fan starts to work, produce vacuum at the nozzle rear portion like this, the material of top inlet point is sucked in the extra heavy pipe, and with the wind together forward, the feed bin that sends away by blast pipe.

4. delivery pipe adopts ball-and-socket type joint, can reduce material to the wearing and tearing of turning tube wall.

5. after material is sent into feed bin, fall into bin bottom behind the release of pressure, dust and finely ground particle substance send the gas port pipeline to enter the bag-type dust mouth through the feed bin upper end, and after filtering, clean air is discharged.

6. the cause owing to malleation is avoided in whole transport systems demand sealing, and contaminated environment.

The specific embodiment

Referring to accompanying drawing 1, be the structural representation of Pneumatic conveyer, this device comprises high pressure positive blower 1, quantitatively exports feed bin 2, vacuum generator 3, airduct 5, big material bin 6, dust exhaustor 7, feed bin valve 8 and bucket elevator 9.High pressure positive blower 1 is as the power of a whole set of feedway, by high pressure positive blower 1 air blast, the control of the large I of air quantity by shutter is to satisfy the requirement of vacuum generator 3 air quantity needs, after producing vacuum, the materials such as stalk of inlet point are sucked airduct 5 and send in the big material bin 6, after material is exerted pressure, automatically drop to big material bin 6 bottoms.Dust enters in the dust exhaustor 7 through the exhaust outlet of quantitatively exporting feed bin 2 ends, filter bag by dust exhaustor 7 falls dust-filtering, clean air enters the atmosphere from exhausr port, and the materials such as stalk are transported to material by feed bin valve 8 and bucket elevator 9 after by the quantitative conveyor screw of big material bin 6 bottoms and carry out charing in the retort 10 and process.

At the turning of airduct 5, adopt the design of ball-and-socket type joint 4, can reduce material to the wearing and tearing of turning tube wall.

Referring to accompanying drawing 2, be the structural representation of vacuum generator.Vacuum generator 3 adopts the design of internal and external casing, be the design of cover tubule in the extra heavy pipe, the air outlet of the straight-through high pressure positive blower 1 in tubule rear end, reduce windage, the tubule front end is apart from the about 150mm in inlet point place of extra heavy pipe, like this when blower fan starts to work, produce vacuum at the nozzle rear portion, the material of top inlet point is sucked in the extra heavy pipe, and with the wind together forward, in the big material bin 6 that sends away by airduct 5.

Vacuum generator 3 adopts the design of internal and external casing, and the tubule rear end leads directly to the high pressure positive blower air outlet, reduces windage, the front extra heavy pipe inlet point about 150mm in the place ahead.

This conveying flow process can install autocontrol valve additional in pipeline, obtain the purpose of carrying to each operation that needs.

The utility model is according to the characteristic of the materials such as stalk, be that density is little, easily wind send, and wind-force requires not too large, and the power with high pressure positive blower send as wind replaces the screw air compressor that generally uses now, the complete equipment of the series of complexes such as storage tank, can save cost, and the sealing of whole transport systems demand, contaminated environment avoided.
