Automatic control process of the present utility model is:
After connecting power supply, timer 14 sends timing signal to master controller 7, master controller 7 gives electromagnetic valve component 9 energisings, after magnetic valve 15 is worked the long periods, when if the situation of overheated or lack of water occurring, the humidity and the temperature sensor 16 that are arranged in the electromagnetic valve component 9 can be given master controller 7 with lack of water or overheated signal feedback, so master controller 7 gives magnetic valve 15 outages, prevent that magnetic valve 15 is because of lack of water or overheated the damage; When spraying, if have people, car through or working face have to blow out and take place or have the running of equipment such as belt conveyer to start, then on-the-spot detector 6 can be given master controller 7 by signal of telecommunication of feedback, master controller 7 gives magnetic valve 15 energisings, connect a supply channel 11 and begin to spray the depositing dust dedusting, when not spraying, if toxic and harmful occurred, then on-the-spot detector 6 can be given master controller 7 by signal of telecommunication of feedback, master controller 7 gives magnetic valve 15 energisings, begin to spray, prevent spreading of toxic and harmful.Master controller 7, magnetic valve are overheated, the physical circuit of excessive low water level protection device 17, timer 14 etc. is a prior art, so this paper is no longer given unnecessary details its physical circuit.
The native system basic functional principle is:
The main-supply 10 that is communicated with the water source, by manual water valve 13 (generally, manual water valve 13 is in normally open, have only maintenance or when needing Artificial Control just with its temporary close), water filter 5, electromagnetic valve component 9, electromagnetic valve component 9 regularly open and close under the control of timer 14 and master controller 7 or according to circumstances open and close on a water supply line 11 a plurality of shower nozzles 8 that can the vaporific water curtain of ejection supply water and form water curtains; Water curtain is arranged on the place that needs the atomizing de-dusting dedusting, and when magnetic valve 15 unlatchings, when current pass through magnetic valve 15, water curtain just can the dedusting of spray sprinkler depositing dust.
The design feature of native system:
Circuit in the master controller 7 is to be that the signal of core is accepted and change-over circuit with the single-chip microcomputer, and the interface of this single-chip microcomputer and on-the-spot detector 6, timer 14 are overheated with magnetic valve, excessive low water level protection device 17 is connected.Look water curtain the different of place and water curtain effective object are set, can set the time of the switching of magnetic valve 15 by the user arbitrarily by the dial-up programmable device that is connected with single-chip microcomputer according to actual conditions, control the switching of magnetic valve 15 by timer 14, with control water curtain atomizing de-dusting; Also can after handling, signal reception, change-over circuit control the suitable switching of magnetic valve by the signal that sensor 6 sends, but generally, be by on-the-spot detector 6 and timer 14 mutually combine, acting in conjunction control magnetic valve opens and closes, be fit to and satisfied needs at the various dust works of China's every profession and trade place atomizing de-dusting dedusting air cleaning.
With the example that is embodied as of the purpose of colliery Da Xiang (being main tunnel under the coal mine) auto spraying and thermal power plant fortune coal Belt Passage auto spraying and requirement, the principle and the function of native system is described.So the industry pertinent regulations, big lane must be provided with automatic sprayer under the coal mine according to China coal, and this device should the long-time continuous atomizing de-dusting, it is distinguished and admirable to purify.Traditional in the past automatic sprayer only has a cover water curtain, and water curtain is arranged on the place of frequent pedestrian's driving, stops spraying when the pedestrian drives a vehicle again, and this has just formed contradiction; And a cover water curtain also has other shortcomings, and for example water curtain below forms easily that excess surface water, mud, track are sunk, sleeper goes mouldy, if having that certain part has been gone bad, package unit is with regard to cisco unity malfunction.And native system is provided with dual-coil electromagnetic valve, two water curtain, the on-the-spot detector of two-way, and the on-the-spot detector on each road is again to be composed in parallel by a plurality of sensors, the user can be according to actual needs, the twice water curtain is arranged to wheel arbitrarily turns over regularly spraying, in case when a direction messenger sends a car, the signal that on-the-spot detector produces will act on signal acceptance, conversion, control circuit, quits work with the water curtain of controlling on this direction, and the still operate as normal spraying of another road water curtain; When certain interval of time people mule carriage was gone, the twice water curtain recovered operate as normal again.Thermal power plant fortune coal Belt Passage compare with colliery Da Xiang to auto spraying require differently, it mainly is to start when transporting coal at belt, requires spray for dust suppression, if when belt and carrying roller rub excessive involuntary ignition in addition, needs fire extinguishing water; Native system can be applicable to that also the thermal power plant belt walks the needs of wide spray sprinkler.Thermal power plant Belt Passage spray sprinkler, mainly be that belt starts, when transportation coal coal dust flew upward, belt started or when experiencing coal on the belt and existing, the master controller 7 of native system will be controlled the water curtain spraying in case the sensor in the on-the-spot detector 6 is experienced.Another main purpose that Belt Passage is provided with the spray sprinkler device prevents the belt spontaneous combustion exactly, too high or the generation smog of temperature can appear in the process of belt from the self-heating to the spontaneous combustion, when temperature sensor in the on-the-spot detector 6 or Smoke Sensor are experienced these situations, native system will start standby water curtain, puts out pyrotechnics.And in the ordinary course of things, 14 control of timer twice water curtain wheel turns over time opening with depositing dust dedusting air cleaning environment.
From above two examples as can be seen, the timer 14 of native system, master controller 7, overheated, the excessive low water level protection device 7 common coordinative roles of magnetic valve, satisfied China's all trades and professions dust the needs of industry place spray sprinkler, depositing dust dedusting air cleaning environment.
