Description
Technical field
The utility model belongs to mining excavation work plane dedusting plant equipment, and is particularly a kind of at driving face, ensures good production environment, helps the healthy comprehensive pick face air curtain control of dust dust pelletizing system of workman.
Technical background
At present, China mine, particularly dust hazard is very serious aborning for the colliery fully mechanized workface, basic solution is not arranged for a long time always, and traditional wet type is caught dirt and is still being used, and this wet type is caught outside the not only a large amount of waste water resource of dust collecting method, and worsened working environment, but efficiency of seizing dust is low and poorer to the regulation effect of respirable dust, causes the ill situation of workman very serious, has seriously influenced the healthy of workman.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of dust collecting effect good, particularly better combines pick face air curtain control of dust dust pelletizing system to breathing dust control of dust dust removing effects.
The technical scheme that the utility model technical solution problem adopts is: a kind of comprehensive pick face air curtain control of dust dust pelletizing system of being made up of development machine, loading scraper-trough conveyer, induced draft fan, induced draft fan motor, high pressure positive blower, high pressure positive blower motor and reclaiming conveyer, its feature is that the air intake vent at induced draft fan is connected with sweep-up pipe, the air draught telescoping tube is equipped with in the stage casing of sweep-up pipe, and air draught telescoping tube left end is equipped with dust shield; At high pressure positive blower air outlet dress pressure ventilation pipe, the pressure ventilation pipe left end connects one and presses the wind telescoping tube, presses wind telescoping tube left end to be connected with the jet case, and jet case and horizonally projected jet chamber are one, and the vertical fluid chamber is connected with the jet case with flexible pipe; Adorn a scraper-trough conveyer fully sheathed case between loading scraper-trough conveyer in the fully-mechanized digging machine and the reclaiming conveyer, scraper-trough conveyer fully sheathed case top is connected with auxiliary sweep-up pipe, and triangle is made in the horizonally projected jet chamber.
The beneficial effects of the utility model are: jet is effective, only use the high pressure positive blower of 1.5KW, the wind speed, the range that obtain more than the 9.5m/s at jet orifice reach 1m, but respirable dust is stopped interception fully, also can tackle substantially the dust that 100～200 μ m fly away in operation, healthy highly beneficial to ensureing the workman's; The system architecture compactness, all system is dragged by fully-mechanized digging machine, and management is simple, and it is little to take up space, and is suitable for low stoop way and uses, and helps driver operation and observes, and prevents that other accident from taking place, and improved work efficiency; Having changed the wet dust removal of prolonging usefulness for a long time is dry dust removal, has saved great amount of water resources, has improved working environment; The design resistance of air curtain equipment is little, volume is little, can regulate the jet exit wind speed and make its even distribution.

The specific embodiment
With reference to accompanying drawing, a kind of comprehensive pick face air curtain control of dust dust pelletizing system, mainly form by development machine 19, loading scraper-trough conveyer 7, induced draft fan 12, induced draft fan motor 13, high pressure positive blower 16, high pressure positive blower motor 15 and reclaiming conveyer 17, its feature is to be connected with sweep-up pipe 9 at induced draft fan 12 air intake vents, telescopic tube 6 is equipped with in the stage casing of sweep-up pipe 9, and telescopic tube 6 left ends are equipped with dust shield 2; At the air outlet dress pressure ventilation pipe 8 of high pressure positive blower 16, pressure ventilation pipe 8 left ends connect one and press wind telescoping tube 5, press wind telescoping tube 5 left ends to be connected with jet case 4, and jet case 4 is an one with horizonally projected jet chamber 3, and vertical fluid chamber 21 usefulness flexible pipes 20 are connected with jet case 3; Adorn a scraper-trough conveyer fully sheathed case 10 between loading scraper-trough conveyer 7 in the fully-mechanized digging machine 19 and the reclaiming conveyer 17, be connected with auxiliary sweep-up pipe 18 between scraper-trough conveyer fully sheathed case 10 tops and the sweep-up pipe 9; Triangle is made in horizonally projected jet chamber 3; Highly little, can play the conversion of kinetic energy, improve static pressure, increase range, reduce the purpose of resistance, and have and take up space for a short time, make things convenient for Si Ji lookout, to realize the target of air curtain envelope dirt.Drill bit 1 is housed on the fully-mechanized digging machine 19 is used for cutting coal petrography; Induced draft fan 12 is provided with fan outlet 11, and is driven by induced draft fan motor 13, and induced draft fan motor 13 is contained on the frame; High pressure positive blower 16 is provided with high pressure positive blower air intake vent 14, and high pressure positive blower 16 is driven by high pressure positive blower motor 15, and high pressure positive blower 16 is contained on the frame.
The dust-cleaning principle of this system: by the rotation of high pressure positive blower 16, new wind is entered from high pressure positive blower air intake vent 14, through pressure ventilation pipe 8, after pressing wind telescoping tube 5 to enter triangle jet case 4, part kinetic energy transforms static pressure, after static pressure raises, flow into horizonally projected jet chamber 3 and vertical fluid chamber 21 by flexible pipe 20, radial flow is to the tunnel peripheral wall surface, form air curtain, termination work plane dust production resource ripple air curtain is enclosed in and sends out the dirt space like this, and the warp-wise jet is decay gradually in course of injection, and under the suction port suction function to termination deflection certain angle, along with angle becomes big, its injection air quantity increases to some extent, and jet and injection are distinguished and admirable with after the tunnel wall contacts, under the effect of wall attachment effect, increase the effective range of jet, and in migration, progressively shunted, flowed to the suction port negative pressuren zone of dust shield 2.This flow field is called " short circuit flow field ", plays jet fully to be mixed disturb the dust of sealing the space, and enters the suction port of dust shield 2, enters induced draft fan 12 through sweep-up pipe 9 again; Simultaneously, induced draft fan 12 also will load dust in the scraper-trough conveyer 7, the dust in the scraper-trough conveyer fully sheathed case 10 sucks through auxiliary sweep-up pipe 18, discharge from fan outlet 11, guarantee the working environment of comprehensive pick face, ensure that the workman's is healthy.
