Description

The automatic adjustable spraying device of volume production

Technical field

The present invention relates to a kind of automatic sprayer, relate in particular to the automatic adjustable spraying device of a kind of volume production.

Background technology

At present, drifting along that most coal mine Xia Huo coal preparation plant causes for belt-conveying flown upward, the situation of contaminated environment, the measure of taking is that the form of automatic vibration formula, mechanical type water spray is carried out depositing dust, the defect of these two kinds of modes is could realize in the time of need to having load on belt, can not water spray dust when belt zero load or belt feeder have just been started, thereby the coal dust that drying function is sticked on belt cannot be processed; In addition, when having load on belt feeder, often again because injection flow rate can not regulate according to the size of load on belt feeder, and cause coal moisture content too high, make coal be easy to stop up sieve aperture in follow-up screening treatment process.Once sieve pore blockade, the lifting of coal, transportation and screening work all must be shut down, and transportation and coal separation operation that this has a strong impact on colliery, cause serious economic loss.Although patent 200720023028.2 has proposed a kind of atomizing de-dusting apparatus that is not subject to the unloaded restriction of travelling belt, this patent still cannot regulate injection flow rate according to the conveying capacity of coal on belt feeder.

The automatic adjustable spraying device of volume production the present invention relates to, can regulate injection flow rate according to the conveying capacity of coal on belt feeder, even do not carry out atomizing de-dusting according to predefined injection flow rate when belt feeder starts yet, avoided existing static pressure sprayer unit by manually opening, can only quantitatively spray and automatic sprayer cannot not realized the technological deficiencies such as atomizing de-dusting when belt feeder starts.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of simple in structure, overcome the defect of prior art, be not subject to the unloaded restriction of travelling belt, and can automatically regulate according to the coal amount of transporting on belt feeder the automatic adjustable spraying device of volume production of injection flow rate, can effectively control injection flow rate, avoid coal when screening, because water content is too high, to produce the phenomenon of plug-hole.

Technical problem to be solved by this invention realizes by the following technical solutions.

The automatic adjustable spraying device of volume production, is comprised of determination of yield sensor, controller, pneumatic diaphragm pump, filter, magnetic valve, flow control valve, pipeline and nozzle.Wherein, determination of yield installation of sensors is in the carrying roller of belt feeder, controller is connected with determination of yield sensor, pneumatic diaphragm pump, magnetic valve and flow control valve by electric wire, the water inlet of filter is connected with water source, its delivery port is connected with pneumatic diaphragm pump, and the air inlet of pneumatic diaphragm pump is connected with source of the gas, and its delivery port is connected with magnetic valve, the delivery port of magnetic valve is connected with flow control valve by pipeline, and the delivery port of flow control valve is connected with nozzle by pipeline.

Described determination of yield sensor is comprised of three pressure sensors, is arranged on respectively in three carrying rollers of belt feeder V-type carrying roller group.Described magnetic valve and flow control valve all adopt flame-proof type control valve, and input power is 24V dc source.

The present invention is set as long-term stopped status by the running status of belt feeder, short-term is shut down and no-load running state, load operation state, by determination of yield sensor, measured four kinds of running statuses of belt feeder, the flow value of the Signal Regulation flow control valve that controller is measured according to determination of yield sensor, and control starts membrane pump, the keying of magnetic valve and flow control valve, and then the batch (-type) in executive chairman's time interval is quantitatively sprayed can to realize belt feeder when long-term stopped status, belt feeder is carried out the batch (-type) of short time interval and is quantitatively sprayed when short-term shutdown and no-load running state, belt feeder is carried out the real-time adjustable spraying of continuous volume production when load operation.

Adopt technique scheme can not be subject to the restriction of belt zero load, while setting belt feeder zero load according to the requirement of depositing dust is completely artificial, spray time and the number of times of fog, when belt feeder load running, can regulate time and the spray flow that sprays fog according to the quantity of transporting coal on belt feeder, thereby the floating dust producing during production drops to smaller state, in the pollution that reduces environment, can also effectively control the water content of coal, to avoid coal to stop up sieve aperture when the follow-up screening.

The pneumatic diaphragm pump volume that the present invention adopts is little, lightweight, install and conveniently moving, and to adopt down-hole source of the gas is power, need not high voltage source, use safe, energy-conservation.This device is compared with electric spraying device, not only has atomizing de-dusting effective, saves water source, maintenance period and service life are all long, and simple in structure, adjust, safeguard simple, particularly can be according to coal conveying capacity adjustable spraying amount, avoid spraying water excessive and stop up sieve aperture.The present invention is applicable to coal mine down-hole tunnel, coal preparation plant etc. and uses belt haulage coal, produces the occasion that dust need to increase atomizing de-dusting.
