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 maximum occupational hazards of China, and in the Work places work of underground coal mine dust pollution, workers with long time sucks a large amount of dust, often suffers from pneumoconiosis.At present, the pneumoconiosis accumulation number of patients of China is more than 600,000 people, and wherein coal industry Pneumoconiosis Patients just reaches 300,000 people, accounts for national Pneumoconiosis Patients about 50%, every year because of the tens billion of unit of direct economic loss that pneumoconiosis causes, indirect economic loss is especially close to hundred billion yuan.
Along with the fast development of driving technology, especially the wide popularization and application of high-productivity faces, add the environmental quality of driving face self: development machine front is one " plug ", turn back after 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 reach 500mg/m when not taking dust prevention
3, some mechanical coal roadway tunneling face is not when taking any dust prevention, and dust concentration is even up to 1000 ~ 3000mg/m
3, the dust of high concentration like this causes serious threat to the production safety of the healthy of underground labour and coal mining enterprise.
For alleviating the above-mentioned threat of high concentrate dust, " safety regulations in coal mine " middle clear stipulaties is respectively exploited mine and must be accomplished " one through three prevention ".Numerous scientific research personnel and field engineering technician study and have explored the 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 development end dedusting, deduster dust removing effects will be better than far away other dust collection methods.But yet there are problems in existing deduster dedusting reality, main cause is exactly that most of deduster structure is single, general is only consider how by distinguished and admirable for dust-laden maximum suction air duct (jet cylinder), and necessary control techniques is often lacked when dust laden air being discharged air duct (jet cylinder), therefore cause the secondary pollution of air, high concentrate dust reality still threatens the health of human body of underground labour and the production safety of coal mining enterprise; Even if some dedusters are structurally also provided with the device that air is discharged in purification, but effect is unsatisfactory.
Such as, patent CN2105991U discloses a kind of cleaner.The water pump that this cleaner comprises ventilating duct (jet cylinder), water tank, water-supply-pipe and driven by explosion separation motor.Be provided with the spiral spray device be fixed on ventilating duct (jet cylinder) axial line at ventilating duct (jet cylinder) inlet side, in ventilating duct (jet cylinder), be provided with gas and water separator at ventilating duct (jet cylinder) outlet side.Also dust collect plant is provided with away from ventilating duct (jet cylinder) outlet side at gas and water separator.Although this cleaner is provided with gas and water separator, essence relies on to arrange grid isolation, has certain effect, still have a large amount of dust laden airs to be discharged by actual use for dust laden air purification nature.
In sum, all the dust laden air of discharging fully cannot be purified for the deduster of development end dedusting in prior art, avoid the secondary pollution of air.
Summary of the invention
The invention provides a kind of dust laden air can discharged jet cylinder to carry out close to the abundant development end cleaner purified.
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 cylinder, the second jet cylinder and the 3rd jet cylinder and high-pressure hydraulic pump; Described first jet cylinder internal fixtion has nozzle, and described nozzle is connected with described high-pressure hydraulic pump, is also provided with strainer between described nozzle and described high-pressure hydraulic pump;
Described second jet cylinder front end is fixedly connected with described first jet tube rear end, and be provided with at least one impeller in described second jet cylinder, described impeller comprises rotating shaft and some blades, and described blade can rotate around described rotating shaft under external impacts;
Described 3rd jet cylinder front end is fixedly connected with described second jet tube rear end, is provided with at least a slice screen pack in described 3rd jet cylinder, and described 3rd jet cylinder lower end is provided with outfall.
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 3rd jet cylinder inwall.
Operating principle of the present invention is as follows:
When described cleaner is started working, described high-pressure hydraulic pump starts, and High-Pressure Water sprays from described nozzle at high speeds, in described first jet cylinder, produce negative pressure; Due to suction function, the high concentrate dust in development end is drawn in described first jet cylinder by force with air, and collides with the current that described nozzle sprays, adsorb, and forms water, gas, dirt mixture; Described mixture is under current high-speed motion, enter into described second jet cylinder, strike the described impeller be installed in described second jet cylinder, the described blade promoted on described impeller rotates around described rotating shaft, due to whipping and the stop of described blade, described high-velocity flow speed reduces, and the water of overwhelming majority mixing, gas, dirt are separated; The water be separated, gas, dirt and small part water, gas, dirt mixture enter in described 3rd jet cylinder; Because the speed of water and dust obviously reduces, therefore, most mix dust water loading on described 3rd jet cylinder inwall, due to the described screen pack effect on described 3rd jet cylinder inwall, water is discharged by described outfall, and dust is blocked in described 3rd jet cylinder; Air only containing a small amount of dust is then discharged from described 3rd jet cylinder rear portion, and dust laden air obtains and purifies 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 discharge cleaner, need through impeller and the multiple effect be separated of the 3rd jet cylinder, therefore, dust laden air only has the dust of 10% to discharge thereupon when being discharged, air obtains purifying comparatively fully.
2. development end cleaner provided by the invention, because dust laden air is being inhaled into cleaner to discharge cleaner, need through impeller and the multiple effect be separated of the 3rd jet cylinder, therefore, high-velocity flow can not be discharged at a high speed from cleaner rear portion, avoids generation casualty accident; Discharge at a high speed from cleaner rear portion owing to not having high-velocity flow, therefore, the present invention allows the speed increasing nozzle ejection current in a big way, improves the dust removing effects of cleaner.
