Description
Technical field:
The utility model relates to a kind of portable mine underground dustfall agent quantitative feeder, belongs to adding of agent technical field, is specifically related to the quantitative waterpower throwing device of a kind of underground coal mine dustfall agent.
Background technology
Produce a large amount of dust in process of coal mining and have a strong impact on the safety of underground coal mine production and the healthy of worker.Clear water atomizing de-dusting is taked in present colliery, but will reach dust-laying effect needs to open atomization mechanism for a long time, and this dust-removing method water consumption is large and cause subsurface environment moist.In clear water, mixing adds dustfall agent and greatly can improve dustfall efficiency, thus guarantees that downhole powder dust concentration is in level of security.
The use procedure of dustfall agent mainly joins in depositing dust clear water with certain proportion, reaches depositing dust object by spray process.Present interpolation dustfall agent has two kinds of major ways, and one adds in pond by dustfall agent, and another kind uses after mixing in the pipeline before adding dustfall agent to depositing dust spraying by electric-power metering pump.Dustfall agent joins in pond by front one, other non-depositing dust spraying water can be caused to be polluted, cause the waste that dustfall agent is unnecessary, simultaneously the bad control of adding proportion of dustfall agent.Rear one adopts electric-power metering pump, and electric-power metering pump voltage adopts 360V, different from 1140V and the 660V voltage of downhole production, and down-hole particular surroundings requires that electric equipment reaches downhole anti-explosion standard, and this just causes the increase of equipment cost.
Underworkings internal spraying place is many, and along with downhole production progress, spraying place constantly changes, and this will ask, and dustfall agent adding device is with low cost, conveniently moving.
Summary of the invention
The utility model is intended to solve the problem, one is provided not need to adopt electric power as power, mine underground dustfall agent throwing device with low cost, conveniently moving, use safety, controllability are strong, this device according to spraying runoff investigation dustfall agent dosage, and can be moved by road wheel easily.
The utility model is achieved through the following technical solutions.
A kind of portable mine underground dustfall agent quantitative feeder, mainly comprises base, road wheel, pressure maintaining valve, flap valve, stop valve, closed container, Venturi tube, liquid capsule, flow meter etc.Closed container is connected with water inlet pipe by pressure maintaining valve; Spinner flowmeter is positioned at the other side of closed container, and liquid capsule, Venturi tube are positioned at closed container inside; Liquid capsule is connected with Venturi tube through flap valve, spinner flowmeter, is provided with flow meter between Venturi tube and outlet pipeline; Closed container is arranged on base, has road wheel under base.
Closed container lower end is connected with stop valve, and liquid capsule upper end is connected with stop valve.Closed container lower end stop valve opens liquid in amount discharge container when overhauling, and liquid capsule upper end stop valve is opened when adding dustfall agent.
Closed container water inlet front end arranges pressure maintaining valve.Pressure maintaining valve can reduce descaling line pressure, and maintains closed container water inlet end pressure stability.
The beneficial effects of the utility model: the utility model apparatus structure is simple, install simple and easy, with low cost, conveniently moving, use safety, controllability are strong.In use procedure without electric power as power, only need the effect of clear water self kinetic energy and negative pressure in supply channel to realize adding of dustfall agent.Device access all can use gladhand to connect, and is convenient to install, and utilizes road wheel, can be convenient mobile according to the change in location of dustproof spray.This device voltage regulation performance is good, ensures that dustfall agent adding proportion is stablized, usually only need add dustfall agent every a few hours in liquid capsule.
