A kind of coal mine movable dust-depositing nozzle pipeline
Technical field
The utility model is related to coal mine atmosphere clean environment technical field, more particularly to a kind of coal mine movable depositing dust Shower nozzle pipeline.
Background technology
In recent years, China industry develops the deterioration for causing environment rapidly, and dust is also cause environmental problem main Pollutant.Most serious person surely belongs to dust hazard in the big occupational hazards of bargh of China four (industrial injury death, dust, poisonous substance, blast).Powder Dirt is deposited to after certain dosage by workman's suction body in respiratory system, may result in the generation of pneumoconiosis.Pneumoconiosis is danger A kind of occupational disease of the most serious of the numerous practitioners' health of evil, is distributed mainly on coal, metallurgy, machinery, building materials, chemical petroleum And the industry such as light industry.How active and effective preventing and treating pneumoconiosis, the problem of be one in the urgent need to address.
Colliery can all discharge substantial amounts of dust in the links such as production, storage, transport and tunnelling into air. Especially in the larger Work places of wind speed, dust discharge amount surges, according to statistics, and some mining areas, which are arranged to the coal dust of air, is More than the 1.6% of coal production.Coal-face is the maximum Work places of colliery dust-producing amount, and its dust-producing amount accounts for mine dust 60% or so of amount.In order to prevent the generation of the serious accidents such as mine gas, coal-dust explosion, improve mine labour health condition, Coal-face is the emphasis of mine dust preventing and treating.Machine mining face is increasingly popularized in China, but dust concentration also rises therewith.Adopt Coal machine cut coal, support move that frame, coal discharge outlet put coal and disintegrating machine breaks the four big dust production resources that coal is machine mining face, and dust-producing amount is respectively about Account for 60%, 20%, 10% and 10% or so.In order to do the dust prevention and control of coal-face well, its dust concentration is effectively reduced, must Corresponding control measures must be taken for the dirt source of coal-face, to reach the purpose that the comprehensive regulation is carried out to dust.
The control measures taken now are usually to set corresponding spray dust remover, to reduce the dense of dust in air Degree, but this dust arrester watering and lowering dust rate is low, and depositing dust form is single, it is impossible to moved according to the need for production, it is impossible to Corresponding safety in production is met to require.
Utility model content
The purpose of this utility model is to provide a kind of coal mine movable dust-depositing nozzle pipeline, can be according to production needs Move, effectively the floating dust amount in reduction air, the security of production environment is greatly improved, using easy to operate.
The technical solution adopted in the utility model is:
A kind of coal mine movable dust-depositing nozzle pipeline, including delivery hose and detachable shower nozzle, the beginning of delivery hose End connection water source, the endcapped of delivery hose;Delivery hose is provided with multiple delivery port necks, the connection spray of delivery port neck thread Head;Described shower nozzle includes the penetrating hollow cylinder shape spray neck and flared head body in two ends, spray neck top connector body it is small Bore end, spray neck inwall is provided with internal thread;The end face at the heavy caliber end of head body is provided with inner circular spray water belt and outer annular water spray Be uniformly provided with multiple spray orifices on band, inner circular spray water belt and outer annular spray water belt, within circular spray water belt extend downwardly and spray neck Top connect to form main jet water channel, being evenly distributed with a plurality of branch along the circumferencial direction of main jet water channel sprays water road, main jet water channel and Every branch water spray road is connected, and every branch water spray road is connected with outer annular spray water belt.
Described spray neck includes upper connection neck and lower mounting neck, upper connection neck and the stepped connection of lower mounting neck, upper company The end difference for connecing neck and lower mounting neck is provided with seal washer, and the inwall of lower mounting neck is provided with internal thread.
Described delivery port neck is provided with external screw thread, and external screw thread matches with internal thread.
The utility model carries out the extension in water route using delivery hose, and multiple detachable shower nozzles are provided with delivery hose, Shower nozzle is recycled to carry out water mist spray;In use, tap is opened, because the end of delivery hose is closing, so, by In the effect of hydraulic pressure so that multiple shower nozzles that current are provided with by delivery hose are sprayed out.Wherein, what current were initially entered is Neck is sprayed, is entered back on main jet water channel and a plurality of branch water spray road, the end face at the heavy caliber end for reaching head body, then be provided with by end face Inner circular spray water belt and outer annular spray water belt are ejected.By the way of central-injection and outer shroud injection, on the one hand it can save About water consumption, on the other hand increases injection pressure so that injection is stronger, and the height of arrival is higher, during whereabouts, The dust of absorption is more.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of shower nozzle of the present utility model;
Fig. 3 is the top view of shower nozzle of the present utility model.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the utility model includes delivery hose 1 and detachable shower nozzle 2, the beginning of delivery hose 1 End connection water source, the endcapped of delivery hose 1;Delivery hose 1 is provided with multiple delivery port necks 3, and delivery port neck 3 is threadedly coupled Shower nozzle 2;Described shower nozzle 2 includes the penetrating hollow cylinder shape spray neck and flared head body in two ends, sprays the top connector body of neck Small-caliber end, spray neck inwall is provided with internal thread;The end face at the heavy caliber end of head body is provided with inner circular spray water belt 4 and outer annular Be uniformly provided with multiple spray orifices 6 on spray water belt 5, inner circular spray water belt 4 and outer annular spray water belt 5, within circular spray water belt 4 to downward Stretch and connect to form main jet water channel 7 with spraying the top of neck, a plurality of branch water spray road 8 is evenly distributed with along the circumferencial direction of main jet water channel 7. It is preferred that, be evenly distributed with a plurality of branch along the circumferencial direction of the bottom of main jet water channel 7 and spray water road 8, every branch water spray road 8 with 40 °- 60 ° of angle of inclination is upwardly extended, and is connected until with outer annular spray water belt 5.Main jet water channel 7 is connected with every branch water spray road 8, Every branch water spray road 8 is connected with outer annular spray water belt 5.Described spray neck includes upper connection neck 9 and lower mounting neck 10, upper connection neck 9 and the stepped connection of lower mounting neck 10, the end difference of upper connection neck 9 and lower mounting neck 10 is provided with seal washer 11, lower to install The inwall of neck 10 is provided with internal thread.Described delivery port neck 3 is provided with external screw thread, and external screw thread matches with internal thread.
Illustrate operation principle of the present utility model below in conjunction with the accompanying drawings:
