Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same technical meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
As shown in fig. 1-6, a dust suppression device of a strip coal storage yard stacker-reclaimer is installed on the strip coal storage yard stacker-reclaimer, and comprises a water supply device, a first nozzle installed at a throwing point at a cantilever rubber belt machine head of the stacker, a second nozzle installed at a trailer blanking hopper, a third nozzle installed in a contour line range of a bottom beam of a gantry of the reclaimer, and fourth nozzles installed at two ends of a guide chute of the reclaimer, wherein water inlet ends of the first nozzle, the second nozzle, the third nozzle and the fourth nozzle are respectively connected with a water outlet pipeline of the water supply device through branch water pipes.
The water supply device comprises a water tank, a high-pressure plunger pump, a 3M fine filter and a high-pressure electromagnetic valve; the water tank, the high-pressure plunger pump, the 3M fine filter and the high-pressure electromagnetic valve are sequentially connected to the inlet of the branch water pipe through a water outlet pipeline; and the control ends of the high-pressure plunger pump and the high-pressure electromagnetic valve are electrically connected with the controller.
And the water outlet pipeline is also provided with a pressure gauge and a pressure transmitter.
And an automatic water return pipe is also connected between the high-pressure electromagnetic valve on the water outlet pipeline and the 3M fine filter, and the other end of the automatic water return pipe is connected in the water tank.
A floating ball liquid level meter is arranged in the water tank and is electrically connected with the controller. The liquid level floating ball meter is used for monitoring the liquid level in the water tank, and the water tank is internally provided with a pump starting water level and a pump stopping water level.
The controller is in communication connection with the upper computer, and the upper computer is connected with the stacker-reclaimer PLC through a ProfiNet bus.
The first nozzle comprises 3 high-pressure micro-mist nozzles 1 with 30-meter shooting ranges, and the first nozzle sprays downwards to impact a large amount of raised dust generated when materials fall on the ground, so that the raised dust is restrained for 2 times, the raised dust at the falling point is covered by 3 high-shooting range fog drops, and no raised dust is ensured on the spot; the second nozzle comprises 8-12 micro-mist nozzles 1 for inhibiting dust at the discharge head, the flow of the nozzle is small, the atomization is good, large-area micro-mist can be formed at the position of the nozzle with the diameter of 2 meters, and dust is inhibited for 1 time.
The third nozzle comprises 20 left and right micro-fog spray heads 1, and downward spraying is carried out to inhibit dust during scraping materials in the coal taking process of the scraper of the material taking machine; the fourth nozzle comprises 3 small-flow micro-mist nozzles for inhibiting the dust at the discharge head.
The dust suppression device further comprises a water cable drum, and a water outlet pipeline is wound on the water cable drum.
A dust suppression device is additionally arranged on stacker-reclaimer equipment and mainly used for providing a stable and sufficient-flow high-pressure water source (the pressure of externally-output high-pressure water is not less than 8 MPa) for a dust fall system so as to generate water mist with the particle size of about 10 microns.
