Description
Technical field
The utility model relates to electric power plant coal transportation gallery dust pelletizing system field, specifically a kind of ventilation post for underground defeated coal gallery dust pelletizing system.
Background technology
A lot of power plant adopts coal on underground gallery, and the underground gallery of power plant is as shown in accompanying drawing 1 ~ 2, and coal conveyer belt is located in gallery, is followed successively by vibration coal feeder, coal bunker and steel double-edged fine-toothed comb above belt.Coal receiving bunker is made up of multiple coal bunker, and both sides can arrange railroad track, also have and do not establish track, directly unloads coal with truck.The coal receiving bunker of current power plant is arranged as shown in accompanying drawing 3 ~ 4, except coal bunker is exactly beams of concrete near it, does not have unnecessary place to arrange the exhaust outlet of deduster, and owing to need to pass through automobile or train coal receiving bunker both sides, therefore can not establish ventilation shaft.So underground defeated coal gallery deduster exhaust duct can only be located in the ground in gallery, cause the reentrainment of dust of underground gallery, cause underground defeated coal gallery dust removing effects bad, environmental quality is not good.
Utility model content
The purpose of this utility model is to provide a kind of ventilation post for underground defeated coal gallery dust pelletizing system, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
For a ventilation post for underground defeated coal gallery dust pelletizing system, comprise cylinder; Described cylinder is hollow tube, and its upper end connects coal receiving bunker awning, and top upwards extends through coal receiving bunker awning, and cylinder lower end connects deduster exhaust duct through coal bunker beams of concrete.
As further program of the utility model: be provided with stiffener and reinforcing bar between described column and coal bunker beams of concrete.
As the utility model further scheme: described main body is made up of seamless steel pipe.
Compared with prior art, the beneficial effects of the utility model are: 1, this ventilation post being used for underground defeated coal gallery dust pelletizing system can greatly improve the working environment of the defeated coal gallery in underground, is conducive to the health of human body of operator; 2, awning column and ventilation shaft unite two into one by this ventilation post being used for underground defeated coal gallery dust pelletizing system, save the area, characteristics of compact layout, succinct; 3, this ventilation post being used for underground defeated coal gallery dust pelletizing system is in process of construction, without the need to increasing civil engineering costs, and reduced investment.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The underground gallery of power plant is as shown in accompanying drawing 1 ~ 2, and coal conveyer belt 2 is located in the ground in gallery 1, is followed successively by vibration coal feeder 6, coal bunker 7 and steel double-edged fine-toothed comb 8 above belt conveyor 2.Coal receiving bunker is made up of multiple coal bunker, and both sides can arrange railroad track, also have and do not establish track, directly unloads coal with truck.The coal receiving bunker of current power plant is arranged as shown in accompanying drawing 3 ~ 4, except coal bunker 7 is exactly beams of concrete near it, does not have unnecessary place to arrange the exhaust outlet of deduster, and owing to need to pass through automobile or train coal receiving bunker both sides, therefore can not establish ventilation shaft.So underground defeated coal gallery deduster exhaust duct 3 can only be located in the ground in gallery 1, cause the reentrainment of dust of underground gallery 1, cause underground defeated coal gallery dust removing effects bad, environmental quality is not good.
Refer to Fig. 5 ~ 6, in the utility model embodiment, a kind of ventilation post for underground defeated coal gallery dust pelletizing system, comprises cylinder 10; Described cylinder 10 is hollow tube, its upper end connects coal receiving bunker awning 13, and top upwards extends through coal receiving bunker awning 13, cylinder 10 lower end connects deduster exhaust duct 3 through coal bunker beams of concrete, preferably, described main body 10 is made up of seamless steel pipe, is provided with stiffener 12 and reinforcing bar 11 between column 10 and coal bunker beams of concrete, stiffener 12 and reinforcing bar 11 are for reinforcing column 10 and coal bunker beams of concrete, and the load transfer that coal receiving bunker awning 13 transmits by cylinder 10 is on coal bunker beams of concrete.
Operation principle of the present utility model is: the deduster exhaust duct 3 of deduster 4 is communicated with cylinder 10, in the deduster 4 dedusting course of work in underground gallery 1, its gas of discharging sends into cylinder 10 by deduster exhaust duct 3, and send into the external world by cylinder 10, thus the reentrainment of dust avoided in underground gallery 1, ensure that the air quality in underground gallery 1.
The corresponding feeder 6 of each coal bunker 7 of underground gallery 1, need a deduster 4 supporting with it, consider coal bunker 7 continuous distributed, therefore each deduster 4 outlet can only utilize two cylinders 10 as discharge duct.The relation of ventilation column diameter and ventilation volume is as shown in the table:
| Ventilation post nominal diameter (mm) | Two ventilation post ventilation (m 3/h) |
| 200 | 3393 |
| 250 | 5301 |
| 300 | 7634 |
| 350 | 10391 |
| 400 | 13572 |
Note: flow velocity is pressed 15m/s and calculated.
The described ventilation post for underground defeated coal gallery dust pelletizing system can greatly improve the working environment of the defeated coal gallery in underground, is conducive to the health of human body of operator; Awning column and ventilation shaft unite two into one by the described ventilation post for underground defeated coal gallery dust pelletizing system, save the area, characteristics of compact layout, succinct; The described ventilation post for underground defeated coal gallery dust pelletizing system in process of construction, without the need to increasing civil engineering costs, reduced investment.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
