Advantage of the present invention is: 1) this device for reducing dust change dedusting is depositing dust, can realize that water level is controlled automatically, the automatic constant proportion example of depositing dust agent is added, machine work and the depositing dust water source automatic Synchronization Control of pressurizeing is adopted, is dug in realization, adopt, pick machine when work can be automatically depositing dust synchronously, and the product dirt position of adopting, dig machine carried out omnibearing depositing dust, solved the dust of adopting, digging machine well and handled problems; 2) can reduce effectively adopt, the dust concentration in pick machine when work; especially can effectively reduce the concentration of respirable dust; dust when having avoided to greatest extent producing produces; improved the operating environment of job site; protected workman's physical and mental health; and guaranteeing the safety in production of mine, is that a kind of desirable wisdom of automatically adopting, dig can device for reducing dust.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, originally adopt, dig quick-witted energy device for reducing dust, be made up of the automatic compression system in depositing dust water source, water level control system and depositing dust agent added automatically system, it is characterized in that: the automatic compression system in described depositing dust water source is made of start-stop control device 7 and force (forcing) pump 9; Described water level control system is made of storage tank 6, high water level control probe 11, low water stage control probe 12, water level controller 15 and electrical ball valve 2; Described depositing dust agent added automatically system is made of depositing dust agent storage bin 4 and current injector 3; Start-stop control device 7 is electrically connected with force (forcing) pump 9 by lead, and be connected to by control line and adopt, on the starting switch of pick machine, the delivery port of force (forcing) pump 9 connects by water under high pressure pipeline 8 to be adopted, the atomization mechanism of pick machine, the water inlet of force (forcing) pump 9 is connected with storage tank 6 by tube connector I 10, be separately installed with high water level control probe 11 and low water stage control probe 12 in the upper and lower of storage tank 6 right side walls, high water level control probe 11 and low water stage control probe 12 all are electrically connected with the water level controller 15 that is positioned at storage tank 6 right sides by lead, depositing dust agent storage bin 4 is installed in the top of water level controller 15, current injector 3 is positioned at depositing dust agent storage bin 4, the delivery port of current injector 3 is connected with storage tank 6 by tube connector II 5, the water inlet of current injector 3 connects mine water source supply channel 1 by electrical ball valve 2, and electrical ball valve 2 is electrically connected with water level controller 15 by lead.Described force (forcing) pump 9, storage tank 6 and water level controller 15 are installed on the base 14, and the two bottom sides of base 14 respectively is equipped with two wheels 13.
Originally adopting, dig quick-witted operating principle that can device for reducing dust is: when adopt, during the work of pick machine, its switching current changes, adopt, the pick machine passes to start-stop control device 7 with current changing signal, start-stop control device 7 starts force (forcing) pump 9 work, force (forcing) pump 9 sucks the depositing dust agent water in the storage tank 6 in it and pressurization, depositing dust agent water becomes high pressure depositing dust agent water after force (forcing) pump 9 pressurizations, high pressure depositing dust agent water enters the atomization mechanism of adopting, digging machine by water under high pressure pipeline 8, and realizes the depositing dust purpose by the atomization mechanism ejection of adopting, digging machine.When the water level of storage tank 6 arrives the position of low water stage control probe 12, low water stage control probe 12 monitors the change in location of water level, and variable signal passed to water level controller 15, and water level controller 15 control electrical ball valves 2 are opened, and electrical ball valve 2 is connected with mine water source supply channel 1; The current injector 3 of press water in electrical ball valve 2 flows into depositing dust agent storage bin 4, under the effect of water flow pressure, current injector 3 produces certain negative pressure, a certain amount of depositing dust agent in the depositing dust agent storage bin 4 is drawn in the press water, like this, press water just becomes the depositing dust agent water that contains the agent of certain proportion depositing dust, and depositing dust agent water flows in the storage tank 6 by tube connector II 5.In said process, when the water velocity of press water is very fast, when flow is big, the negative pressure that current injector 3 produces is also bigger, the depositing dust agent that is drawn in the press water is just many, otherwise the negative pressure that current injector 3 produces is less, and the depositing dust agent that is drawn in the press water is also just fewer, sucking the flow of depositing dust agent and the flow-rate ratio of press water is a definite value, thereby the constant proportion that has realized the depositing dust agent is added; Change the adding proportion of depositing dust agent in the press water if desired, the flow velocity that only needs to adjust press water in the mine water source supply channel 1 can be realized.When the water level of storage tank 6 arrived the position of high water level control probe 11, high water level control probe 11 was passed to water level controller 15 with signal, and water level controller 15 control electrical ball valves 2 are closed, and mine water source supply channel 1 stops to device for reducing dust for press water.
