Description

Volume production is regulated sprayer unit automatically

Technical field

The present invention relates to a kind of automatic sprayer, relate in particular to a kind of volume production and regulate sprayer unit automatically.

Background technology

At present; Mostly under the coal mine or coal preparation plant transportation causes to belt drift along fly upward, the situation of contaminated environment; The measure of being taked is that the form of automatic oscillatory type, mechanical type water spray is come depositing dust; The defective of this dual mode is could realize in the time of need on belt, load being arranged, can not water spray dust when belt zero load or belt feeder have just been started, thereby can't handle the coal dust that air-dry effect sticks on the belt; In addition, when on the belt feeder load being arranged, often, and cause the coal moisture content too high, make coal in follow-up screening treatment process, be easy to stop up sieve aperture again because injection flow rate can not be regulated according to the size of load on the belt feeder.In case sieve pore blockade, the lifting of coal, transportation and screening work all must be shut down, transportation and coal separation operation that this has a strong impact on the colliery cause serious economy loss.Although patent 200720023028.2 has proposed a kind of atomizing de-dusting apparatus that does not receive the unloaded restriction of travelling belt, this patent still can't be regulated injection flow rate according to the conveying capacity of coal on the belt feeder.

The volume production that the present invention relates to is regulated sprayer unit automatically; Can regulate injection flow rate according to the conveying capacity of coal on the belt feeder; Even when belt feeder starts, do not carry out atomizing de-dusting according to predefined injection flow rate yet; Avoided existing static pressure sprayer unit to open, can only quantitatively spray and automatic sprayer can't be realized technological deficiencies such as atomizing de-dusting when belt feeder does not start by manual work.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of simple in structure; Overcome the defective of prior art; Do not receive the unloaded restriction of travelling belt; And can regulate sprayer unit automatically according to the volume production that the coal amount of transporting on the belt feeder to regulate injection flow rate automatically, and can effectively control injection flow rate, avoid coal when screening, to produce the phenomenon of plug-hole owing to water content is too high.

Technical problem to be solved by this invention adopts following technical scheme to realize.

A kind of volume production is regulated sprayer unit automatically, is made up of determination of yield sensor, controller, pneumatic diaphragm pump, filter, magnetic valve, flow control valve, pipeline and nozzle.Wherein, the determination of yield sensor is installed in the carrying roller of belt feeder, and controller is connected with determination of yield sensor, pneumatic diaphragm pump, magnetic valve and flow control valve through electric wire; The water inlet of filter is connected with the 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 through pipeline, and the delivery port of flow control valve is connected with nozzle through pipeline.

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

The present invention is set at long-term stopped status, short-term shutdown and no-load running state, load operation state with the running status of belt feeder; Three kinds of running statuses by determination of yield sensor determination belt feeder; Controller is according to the flow value of the Signal Regulation flow control valve of determination of yield sensor determination; And control starts the keying of membrane pump, 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, and the batch (-type) that short time interval was shut down and carried out during the no-load running state to belt feeder in short-term is quantitatively sprayed, and belt feeder is carried out continuous volume production real-time regulated and sprayed when load operation.

Adopt technique scheme can not receive the unloaded restriction of belt; Spray the time and the number of times of fog when setting the belt feeder zero load according to the requirement of depositing dust is artificial fully; The quantity of transportation coal is regulated time and the spray flow that sprays fog on can be according to belt feeder when the belt feeder load running; Thereby the floating dust that produces when producing drops to smaller state, in the pollution that reduces environment, can also effectively control the water content of coal, stops up sieve aperture when the follow-up screening to avoid coal.

The pneumatic diaphragm pump volume that the present invention adopts is little, in light weight, install and conveniently moving, and to adopt the down-hole source of the gas is power, need not high voltage source, and safe in utilization, energy-conservation.This device is compared with electric spraying device, and it is effective not only to have an atomizing de-dusting, practices thrift the water source; Maintenance period and service life are all long, and simple in structure, adjust, safeguard simple; Particularly can regulate spray amount, avoid spraying water excessive and the obstruction sieve aperture according to the coal conveying capacity.The present invention is applicable to that colliery underworkings, coal preparation plant etc. use belt conveyor transportation coal, produce the occasion that dust need increase atomizing de-dusting.
