At present, generally adopt water pipe carry out sprinkle water and spray dedusting or utilize blower fan purifying and dedusting for a large amount of coal dusts, though wherein sprinkle water and spray dedusting is simple, water consumption causes greatly the waste of water resource; And blower fan purifying and dedusting exists the limited problem of air quantity of processing, dust removing effects is poor, and the power consumption of starting shooting is continuously large.
Utility model content
The utility model is exactly in order to overcome the above problems, and the coal mine dedusting device of a kind of on-line monitoring and dedusting is provided, and reaches the object of on-line monitoring automatic dust removing.
In order to achieve the above object, the utility model provides the coal mine dedusting device of a kind of on-line monitoring and dedusting, comprise be located at top, tunnel for detection of the dust sensor of dust concentration with for the shower nozzle of spray for dust suppression, the output of described dust sensor carries out signal with switch board and is connected, the water pipe that connects shower nozzle is provided with electromagnetic valve, and the input of described electromagnetic valve is electrically connected with described switch board; In described tunnel, be also provided with blower fan, the power switch of described blower fan is electrically connected with described switch board.
Further, near described shower nozzle, be provided with infrared sensor, described infrared sensor hanging is connected with switch board on top, tunnel and by electric wire.
Further, described infrared sensor has two, is hung on respectively the top, forward and backward side tunnel of shower nozzle.
Further, described switch board comprises single-chip microcomputer, and the output of described single-chip microcomputer is connected with warning device; Described single-chip microcomputer carries out electric wire with described dust sensor, electromagnetic valve, power switch, infrared sensor respectively and is connected.
Switch board is also provided with display unit, and switch board also can by CAN bus with establish aboveground control room and carry out communication and control.
Dust arrester of the present utility model combines spray for dust suppression and blower fan purifying and dedusting, can effectively remove the dust in tunnel, has protected that staff's is healthy.Also can select to open atomizing de-dusting and blower fan dedusting according to Dust Capacity actual in tunnel, thereby reach saving water resource and electric energy, and protect the running reliably and with long-term of equipment.The impact on staff for fear of spray for dust suppression simultaneously, this device is also provided with infrared sensor, in the time that its induction has detected that staff is near shower nozzle, reach and control the switch of shower nozzle by controlling electromagnetic valve, avoid water to be spread across with it staff.
Dust arrester of the present utility model has been realized colliery downhole powder dust on-line continuous monitoring and monitoring, has the functions such as the warning of downhole powder dust concentration over-standard, auto spraying and dust-removing, remote monitoring; Realize remote dust on-line continuous Real-Time Monitoring monitoring and information management, reduced face dust concentration; Embody dustlessization of work plane management, to the comprehensive regulation of downhole powder dust, improved working environment, reduced that occupational hazards has important practical significance and social benefit.
This device combines infrared sensor and spray for dust suppression, realizes and has people to pass through, and shower nozzle stops spraying automatically; Later auto spraying again of people.
Dust monitoring concentration can be first set interval is 0.1-500mg/m3, dust warning concentration is 10mg/m3, in the time that dust sensor detects that dust concentration is greater than 10mg/m3, the electromagnetic valve of automatically opening on water pipe is sprayed, and the power switch of opening blower fan carries out blower fan purifying and dedusting simultaneously, can reach fast the object of dedusting; Until dust concentration drops to below warning concentration, electromagnetic valve and power switch are closed automatically, stop spray for dust suppression and blower fan purifying and dedusting, thereby reach the object of saving water resource and electric energy.This alarm is also removed.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model schematic block circuit diagram;
In figure: 1-blower fan, 2-power switch, 3-switch board, 3-1 single-chip microcomputer, 3-2 warning device, 4-water pipe, 5-electromagnetic valve, 6-dust sensor, 7-1 the first infrared sensor, 7-2 the second infrared sensor, 8-shower nozzle, 9-tunnel.
Detailed description of the invention
As shown in Figure 1, 2, the coal mine dedusting device of a kind of on-line monitoring and dedusting, comprise and be located at 9 tops, tunnel for detection of the dust sensor 6 of dust concentration, for the shower nozzle 8 of spray for dust suppression, and for the blower fan 1 of blower fan purifying and dedusting, in tunnel 9, be provided with switch board 3, switch board 3 comprises single-chip microcomputer 3-1 and warning device 3-2, and the output of described single-chip microcomputer 3-1 is connected with warning device; The input of described single-chip microcomputer 3 one 1 is connected with the output of dust sensor 6, the first infrared sensor 7-1, the second infrared sensor 7-2 respectively, its output respectively be located at electromagnetic valve 5 on the water pipe 4 that is connected shower nozzle 8, the power switch 2 of controlling blower fan 1 start-stop, warning device 3-2 and connect.
