Description
Technical field
The present invention relates to a kind of cleaner, particularly a kind of development end cleaner.
Background technology
Mine dust is one of occupational hazards of China's maximum, the operation place of dust pollution work under coal mine, and workers with long time sucks a large amount of dust, tends to suffer from pneumoconiosis.At present, the pneumoconiosis accumulation number of patients of China surpasses 600,000 people, and wherein coal industry pneumoconiosis patient just reaches 300,000 people, accounts for national pneumoconiosis patient about 50%, the tens billion of units of direct economic loss that cause because of pneumoconiosis every year, indirect economic loss is especially near hundred billion yuan.
Fast development along with driving technology, especially the wide popularization and application of high-yield and high-efficiency work plane, add the environmental quality of driving face self: development machine the place ahead is one " plug ", turn back behind the distinguished and admirable chance rib, carry a large amount of dust and blow to development end staff place, the dust concentration of driving face can not reach 500mg/m when taking dust prevention
3, part mechanization coal road development end when not taking any dust prevention, dust concentration even up to 1000～3000mg/m
3, so the dust of high concentration causes serious threat for the production safety of underground labour's healthy and coal mining enterprise.
For alleviating the above-mentioned threat of high concentrate dust, stipulate clearly in " safety regulations in coal mine " that respectively exploiting mine must accomplish " one through three prevention ".Numerous scientific research personnel and field engineering technician study and have explored multiple dust collection methods such as high-pressure fog, water curtain dedusting, dust removal by ventilation, deduster dedusting in succession through unremitting effort, but through application practice, for the development end dedusting, the deduster dust removing effects will be better than other dust collection methods far away.But yet there are problems in existing deduster dedusting reality, main cause is exactly that most of deduster structures are single, generally only be to have considered how with in the distinguished and admirable maximum suction air duct of dust-laden (jet tube), and when dust laden air being discharged air duct (jet tube), often lack necessary control techniques, therefore caused the secondary pollution of air, high concentrate dust reality is still threatening underground labour's health of human body and the production safety of coal mining enterprise; Purify the device of discharging air even if some dedusters structurally also are provided with, but effect is unsatisfactory.
For example, patent CN2105991U discloses a kind of cleaner.This cleaner comprises ventilating duct (jet tube), water tank, water-supply-pipe and the water pump that is driven by explosion separation motor.Be provided with the spiral spray device that is fixed on ventilating duct (jet tube) axial line at ventilating duct (jet tube) inlet side, in ventilating duct (jet tube), be provided with gas and water separator at ventilating duct (jet tube) outlet side.Also be provided with dust collect plant at gas and water separator away from ventilating duct (jet tube) outlet side.Though this cleaner is provided with gas and water separator, essence is to rely on the isolation of grid sheet is set, and purifying nature for dust laden air has certain effect, and using by reality still has a large amount of dust laden airs to be discharged from.
In sum, the deduster that is used for the development end dedusting in the prior art all can't fully purify the dust laden air of discharging, and avoids the secondary pollution of air.
Summary of the invention
The invention provides a kind of development end cleaner that can approach abundant purification to the dust laden air that the jet tube is discharged.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of development end cleaner comprises the first jet tube, the second jet tube and the 3rd jet tube and high-pressure hydraulic pump; In the described first jet tube nozzle is arranged fixedly, described nozzle is connected with described high-pressure hydraulic pump, between described nozzle and the described high-pressure pump strainer is installed also;
The described second jet tube front end is fixedlyed connected with the described first jet tube rear end, in the described second jet tube at least one impeller is installed, and described impeller comprises rotating shaft and some blades, and described blade can be around described rotating shaft rotation under external impacts;
Described the 3rd jet tube front end is fixedlyed connected with the described second jet tube rear end, in described the 3rd jet tube a slice screen pack at least is installed, and is provided with outfall in described the 3rd jet tube lower end.
At above-mentioned cleaner, described impeller is one.
At above-mentioned cleaner, described screen pack is a slice.
At above-mentioned cleaner, described screen pack is installed on described the 3rd jet tube inwall.
Operating principle of the present invention is as follows:
When described cleaner was started working, described high-pressure hydraulic pump started, and High-Pressure Water sprays at a high speed from described nozzle, produces negative pressure in the described first jet tube; Because suction function, the high concentrate dust in the development end is drawn in the described first jet tube by force with air, and with current collision, the absorption of described nozzle ejection, form water, gas, dirt mixture; Described mixture is under the current high-speed motion, enter into the described second jet tube, strike the described impeller that is installed in the described second jet tube, the described blade that promotes on the described impeller rotates around described rotating shaft, because the whipping of described blade and stopping, described high-velocity flow speed reduces, and water, gas, dirt that the overwhelming majority is mixed separate; The water, gas, dirt and minimum part water, gas, the dirt mixture that separate enter in described the 3rd jet tube; Because the speed of water and dust obviously reduces, therefore, most mix dust water and are attached on described the 3rd jet tube inwall, because the described screen pack effect on described the 3rd jet tube inwall, water is discharged by described outfall, and dust is blocked in described the 3rd jet tube; The air that only contains low amounts of dust is then discharged from described the 3rd jet tube rear portion, and dust laden air has obtained purifying comparatively fully.
Technique scheme of the present invention has the following advantages compared to existing technology:
1. development end cleaner provided by the invention, because dust laden air is being inhaled into cleaner to discharging cleaner, need through impeller and the multiple effect that separates of the 3rd jet tube, therefore, dust laden air only has 10% dust to discharge when being discharged from thereupon, and air obtains purifying comparatively fully.
2. development end cleaner provided by the invention, because dust laden air needs through impeller and the multiple effect that separates of the 3rd jet tube, therefore being inhaled into cleaner to discharging cleaner, high-velocity flow can not discharged at a high speed from the cleaner rear portion, has avoided the generation casualty accident; Because not having high-velocity flow discharges at a high speed from the cleaner rear portion, therefore, the present invention allows to increase the speed of nozzle ejection current in a big way, improves the dust removing effects of cleaner.
