Description

A kind of auto spraying device for reducing dust
Technical field
The utility model relates to a kind of atomization mechanism, is specifically related to a kind of auto spraying device for reducing dust that is used for product dirt places such as colliery.
Background technology
In the colliery, the environment of underground work generally all compares badly, be easy to generate coal dust and coal ash, bring very big infringement for staff's health, cause some occupational diseases such as pneumoconiosis,, prevent contingent dust explosion accident in order to reduce the coal dust that coal yard produces, reduce the danger that operating personnel suffer from pneumoconiosis, " safety of coal mines return journey " regulation will should be taked dust prevention to the place that produces coal dust.But the colliery does not have control measures substantially to intake, belt transfer point at present, the return aircourse, and the coal yard transfer point is taked the static pressure water spray usually and is pounced on dirt curtain integrated dust-removing, perhaps adopts measures such as electrical dust-removing air duct or electric atomizing.
The static pressure water spray is to produce dirt place installation watering dust suppression device.This watering dust suppression device mostly is to link by the control of manually-operated hand switch or with transporter.Atomization mechanism was opened when transporter started, no matter have coal not have coal on the transporter, dust suppression device by water spray is watering and lowering dust in the same old way all.This mode one is to waste water, the 2nd, and the inhomogeneous effect that the water yield is spread is bad, also can influence the quality of coal when the water yield is excessive.
The depositing dust mode of electric atomizing is that electromagnetic starter and water pump are installed in the down-hole, utilizes the water pump supercharging, and water under high pressure is flowed to spray boom, forms water smoke by the ejection of the nozzle on the spray boom, utilizes hydraulic pressure to produce the content that spraying reduces dust in the air.But existing starter and water pump generally all are kilograms up to a hundred, and the space, down-hole is narrow and small in addition, and transportation is very inconvenient, also are not easy to install; In addition, starter and water pump are all wanted electricity consumption, so also need to consider explosion-proof problem.If directly use to the down-hole from water receiving source, ground, air pressure is less when generally using, and can not produce spraying, and just as watering, so dust-laying effect is poor, water consumption is very big, and forms the water coal easily, influences the quality of coal, and power consumption is bigger, and noise is big.
China Patent No. ZL200520024116.5 name is called " transfer point automatic sprayer " and discloses a kind of atomization mechanism, comprise belt conveyer, electromagnetic valve, sensor, spraying water nozzle, sensor is positioned at the top of belt conveyer, be connected with magnetic starter with cable, magnetic starter is connected with electromagnetic valve with cable, and electromagnetic valve one end is connected with the spraying water nozzle, and the other end is connected with supply channel.This electronic depositing dust mode does not have supercharging device, and its defective can not produce spraying as mentioned above, and dust-laying effect is poor, and water consumption is big, and forms the water coal easily, influences the quality of coal, and power consumption and noise are also all bigger in addition.
The utility model content
The purpose of this utility model provides a kind of auto spraying device for reducing dust, to solve the installation and transportation inconvenience in the transfer point of down-hole or airway of existing atomization mechanism, the not high and unfavorable problem of result of use of safety.
For achieving the above object, the utility model adopts following technical scheme: a kind of auto spraying device for reducing dust, this device comprises sprayer unit and control module, sprayer unit comprises that at least one has the shower nozzle of nozzle, control module comprises an air driven pump, the air inlet port of air driven pump is used for being connected with source of the gas, and water inlet is used for being connected with the water source, and delivery port is connected with ejecting device by supply channel.
Described control module is provided with a controller and detecting sensor, and the supply channel of air driven pump delivery port is provided with a motor operated valve, and the signal input part of described controller links to each other with detecting sensor, and its control output end is connected with motor operated valve control.
Described detecting sensor is a sensor of dust concentration, is connected with the signal input part of controller, is used to be located in the spray area to detect this regional environment concentration.
This device comprises import monitoring sensor and the outlet monitoring sensor that is used to be located at place, spray area both sides, described import monitoring sensor and outlet monitoring sensor all with the controller control connection.
The air inlet port of described air driven pump is provided with the bleed pressure table, and the water side of air driven pump is provided with water pressure gauge.
The water inlet of described air driven pump is provided with strainer.
Described ejecting device is the rotating sprinkler group.
Auto spraying device for reducing dust of the present utility model adopts air driven pump to combine with spraying nozzle, realizes atomizing de-dusting, and the spraying that forms is sprayed evenly, and effect is better, and ature of coal is not had influence.In addition, the volume of air driven pump is less, and is in light weight, installation, transportation, conveniently moving; Use compressed air to be power, need not high voltage source, safe in utilization, energy conservation; Because all working zone, colliery possesses pressure 0.3~1MPa compressed air, the scope of application is wider; This device is compared with electric spraying device, and operating frequency is low, so maintenance period and application life are all longer.
In addition, control module adopts controller, motor operated valve and sensor to combine, and sensor adopts sensor of dust concentration, dust concentration in order to the testing environment, according to the automatic control of measurement result realization to motor operated valve, intelligent degree height need not the special messenger and keeps an eye on.
Be further optimization, this device also is provided with import monitoring sensor and outlet monitoring sensor in spray area, and with the controller control connection, as personnel through or in spray area when movable, sensor can be responded to automatically, and by host computer control motor operated valve closure, when nobody the time resume work automatically.
Be further to optimize, this device is provided with bleed pressure table and water pressure gauge respectively at the air inlet port and the delivery port of air driven pump, at the water inlet of air driven pump strainer is set, and makes device use more intuitive and convenient, safe relieved.
In addition, adopt the rotating sprinkler group to make the sprinkling zone wider, evenly spray, effect is even more ideal.
