Abstract
The utility model discloses a comprehensive dust suppression system for a whole-rock fully-mechanized excavation face. A negative pressure dedusting fan is fixed on a development machine; both sides of a cutting arm of the development machine are respectively provided with exhaust openings, and the exhaust openings are connected with the dedusting fan through rotatable air suction ducts; a pressed fan is arranged at a fresh air port of a roadway, an outlet of a fan drum is arranged at the middle part of a top plate of the roadway of the fully-mechanized excavation face, so that fresh air enters the middle upper part of the roadway and returns from both sides of the lower part of the roadway; and the pressed fan drum is provided with an air control valve. After the comprehensive dust suppression system is applied on site, the dust concentration at the position of a driver of the development machine is reduced from 680mg/m<3> to 13.7mg/m<3>, and the dust suppression efficiency reaches 97.9%.
Description
Technical field
The utility model relates to driving face treating flour dust technology under the coal mine.
Background technology
The comprehensive digging of colliery total rock is at present advanced work plane and is adopted boom-type roadheader.Because the big (25.6m of section
2), big, the big (425m of air distribution amount of development machine power
2/ characteristics such as min) have been brought big, the with serious pollution problem of Dust Capacity to getting working face, and the dust concentration of meeting head on during operation reaches 600～700mg/m
3, serious threat worker's the safety in production of healthy and mine.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of total rock fully mechanized workface integrated dust-removing system.
The technical scheme that the utility model is taked is:
On development machine, fix a depression dust-removing blower fan; Install the inlet scoop respectively in tunneling machine cutting arm both sides, the inlet scoop is connected with dedusting fan by rotary type air draught road.
Install forced blower fan at the tunnel fresh wind port, the air duct outlet is arranged in roadway workface top board middle part, makes the middle and upper part, tunnel advance new wind, both sides, bottom return air; The control air-valve is set on forced air duct, face air volume is carried out flexible modulation, make to be pressed into air quantity and the dedusting fan suction air volume mates mutually.
The utility model has the advantages that: through The field, the fully-mechanized digging machine driver locates dust concentration by 680mg/m
3Dropped to 13.7mg/m
3, depositing dust efficient has reached 97.9%.
Description of drawings
Fig. 1 is the schematic top plan view of the utility model embodiment.
Marginal data: 1-development machine; 2-depression dust-removing blower fan; The 3-inlet scoop; The rotary air draught of 4-road; The forced blower fan of 5-; The 6-air duct; The outlet of 7-air duct; 8-is controlled air-valve.
The specific embodiment
As shown in Figure 1, the utility model is to fix a depression dust-removing blower fan 2 on development machine 1; Install inlet scoop 3 respectively in development machine 1 cutting arm both sides, inlet scoop 3 is connected with depression dust-removing blower fan 2 by rotary type air draught road 4.
Install forced blower fan 5 at the tunnel fresh wind port, air duct outlet 7 is arranged in roadway workface top board middle part, makes the middle and upper part, tunnel advance new wind, both sides, bottom return air; Control air-valve 8 is set on forced blower fan air duct 6, face air volume is carried out flexible modulation, make to be pressed into air quantity and depression dust-removing blower fan 2 suction air volumes mate mutually.
