Description
Technical field
The utility model relates to the wet automatic spray dust removal device that detects of doing of coal conveyor belt, specifically a kind of mining wet automatic spray dust removal device that detects of doing.
Background technology
Along with the development in epoch, the raising of production efficiency, belt conveyer presents growthization, but belt conveyer because the coal overdrying produces a large amount of dust, endangers health of human body in operation process, affect the safety in production of mine.At present popular is some artificial mechanism watering or vibrating type automatic water systems, and its defective is wet regardless of doing of coal, as long as the belt conveyer running has coal namely to spray, causes the moisture of coal excessive, and ature of coal runs off, waste water resource.
The utility model content
For the problems referred to above of existing belt conveyer automatic water system, the purpose of this utility model provides a kind of wet detection of doing, and the wet automatic spray dust removal device that detects is done in automatically control, simple in structure, installation and maintenance easily belt conveyer.
In order to achieve the above object, the utility model adopts following technical scheme: the mining detection automatic spray dust removal device that wets of doing, comprise and do wet detecting sensor, multipurpose main controller and electromagnetic valve, it is characterized in that: do wet detecting sensor bottom the coal belt conveyer is set, two detector bars are set dried wet detecting sensor and the coal belt conveyer adapts, the output of doing wet detecting sensor connects the multipurpose main controller, and the output of multipurpose main controller connects the electromagnetic valve of atomization mechanism.
When turning round, the coal belt conveyer having in the situation of dry coal, when the detector bar of dried wet detecting sensor receives a high resistance vibration signal, after the internal circuit of dried wet detecting sensor amplifies by shaping, export a voltage signal to the multipurpose main controller, the multipurpose main controller receives signal by the little processing of single-chip microcomputer, send an instruction, it is electric that electromagnetic valve is got, and opens electromagnetic valve and spray to dry coal.When the humidity of coal surpasses setting value (adjustable), the detector bar of doing wet detecting sensor receives a low resistance moisture signal, dried wet sensor circuit counter-rotating, output voltage is zero, the multipurpose main controller does not receive signal, gives the solenoid valve shuts power supply, and spraying stops.
Wherein preferred version is:
Describedly do the middle position that wet detecting sensor is hung vertically in the coal belt of belt conveyor, two detector bars are respectively perpendicular to 1/3 and 2/3 place of belt width, apart from belt 8mm-20mm.
The described detecting sensor that wets of doing comprises anti-riot housing, wiring board and cable entry, and explosion-proof casing inside arranges wiring board, and wiring board connects outside this power supply of peace and multipurpose main controller by cable entry.
The described explosion-proof casing of doing wet detecting sensor arranges rotating shaft, rotating shaft one end detector bar, and other end setting half serrated wheel, the sawtooth of half serrated wheel adapts with the correlation photoelectric tube that is arranged on wiring board.
The beneficial effect that the utlity model has is: the multipurpose main controller is the specific (special) requirements according to Safety of Coal Mine Production; adopt the anti-explosion product of Flameproof intrinsically safe circuit design; dual current protection and dual voltage protection in the essential safe type circuit, have been designed; excessive or the short circuit generation spark of prevention electric current; cause gas or coal-dust explosion, protected personnel's life security and device security.According to put prevention first, the policy of safety first, designed flame proof parameter and intrinsic safety parameter all surpass state specified standards and industry required standard.At the wet automatic spray dust removal device that detects of doing of utility model, compare with atomization mechanism in the past, it can detect humidity automatically, and saves labor, and has that highly sensitive, simple in structure, failure rate is low, volume are little, lightweight, installation and an advantage such as easy to maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of half serrated wheel of the present utility model;
Wherein: 1, detector bar 2, explosion-proof casing 3, wiring board 4, cable entry 5, half serrated wheel 6, rotating shaft 7, sawtooth.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1 and Figure 2, do wet detecting sensor bottom the coal belt conveyer is set, dried wet detecting sensor arranges two detector bars 1 and adapts with the coal belt conveyer, the output of doing wet detecting sensor connects the multipurpose main controller, and the output of multipurpose main controller connects the electromagnetic valve of atomization mechanism.
Do the middle position that wet detecting sensor is hung vertically in the coal belt of belt conveyor, two detector bars 1 are respectively perpendicular to 1/3 and 2/3 place of belt width, apart from belt 8mm-20mm.
Do wet detecting sensor and comprise anti-riot housing 2, wiring board 3 and cable entry 4, explosion-proof casing 2 inside arrange wiring board 3, and wiring board 3 connects outside this power supply of peace and multipurpose main controller by cable entry 4.
The explosion-proof casing 2 of doing wet detecting sensor arranges rotating shaft 6, rotating shaft 6 one end detector bars 1, and the sawtooth 7 of other end setting half serrated wheel 5, half serrated wheels 5 adapts with the correlation photoelectric tube that is arranged on wiring board 3.
Operating principle: from the intrinsic safety electric source of multipurpose main controller output and holding wire with cable by doing the cable entry 4 of wet detecting sensor, be connected on the wiring terminal.The intrinsic safety electric source of 12v is given and is done wet detecting sensor power supply.
