Abstract
The utility model relates to a pulse pneumatic coal-bloating resistant device, which is a device for preventing various coal storing bunkers from bloasting coal. The utility model is characterized in that the set of device is positioned at the circumference outside the lower part of the coal storing bunker, and is composed of an air pipeline and an air nozzle. A pulse signal generator is arranged on a main air pipe. When occurring coal bloasting, a coal breaking-off signal switches on the pulse signal generator, and simultaneously, switches on a pulse control air valve, so as to jet a high pressure air flow to a coal bloasting layer, and the arch of the coal bloasting layer can be destroyed, so as to a coal layer is fallen. The utility model has the advantages of simple device, less investment, automatic control, safe operation, worry saving, and labor saving, and is suitable for installation and use for various coal storing bunkers.
Description
One, technical field
The utility model relates to a kind of device that prevents various coal store canopy coals.
Two, background technology
In enterprises such as power plants, coal all will leave in earlier in the big coal bunker before entrucking, conveying and use, allows it fall naturally when entrucking, conveying and use, transports then.In practical operation, coal and unlike the imagination by gravity fall naturally, canopy coal phenomenon often takes place, cause disconnected coal.This is one and seems simple question, but all there is and fails to obtain the problem of fine solution in all power plant.The canopy coal all is the state of overarching, and its bearing capacity is very big, wants to allow the coal normal descend, the arch that forms must be destroyed, and does not perhaps allow it form arch.During reality was produced, the major measure that people take has: as manpower hammering method, vibrating motor method etc., but effect was all undesirable.
Three, summary of the invention
Key of the present utility model is a kind of pulse pneumatic coal-bloating resistant device of design, to solve the canopy coal problem that exists in the reality production.
Implementation procedure of the present utility model is such: design and installation has air duct around the outside, coal bunker bottom, admission port at air duct is provided with the control by pulses air valve, disconnected coal signal adopts the disconnected coal signal on the feeder, all is provided with the air nozzle that several make progress on the every air duct.According to the height of frequent canopy coal, two to three layer of air pipelines can be set, every layer of air pipeline is equipped with a control by pulses air valve, is provided with pulse signal generator on gas main.For preventing air spray obstruction, be provided with the device of an anti-chute blockage at the nozzle place.
Good effect of the present utility model is: equipment is simple, and small investment is easy for installation, can utilize power plant to have source of the gas (if not having the unit of source of the gas can utilize Air compressor) now, and over-the-road expense is very low; System design is automatic guidance, and is safe and reliable, good operation, and it is laborsaving to save worry, and not only is fit to power plant's coal bunker and uses, and also is fit to other coal yard coal bunker and uses.
Four, description of drawings
Fig. 1 is a running condition scheme drawing of the present utility model, and Fig. 2 is the birds-eye view of Fig. 1.
Five, the specific embodiment
As shown in Figure 1 and Figure 2, around the outside, coal bunker 6 bottoms, be provided with two-layer air duct 5, admission port at every layer of air pipeline 5 is equipped with control by pulses air valve 4, is provided with air nozzle 2 straight up on every air duct 5, is provided with pulse signal generator on gas main.For preventing that air nozzle from blocking, on air nozzle, be provided with anti-block apparatus, anti-block apparatus is such: be provided with at least three brace rods at the edge of air nozzle 2, fix the lid of a umbrella shape above the brace rod, air can be from the umbrella shape lid down towards ejection all around.
Working process of the present utility model is: with the power supply of disconnected coal signal control pulse signal generator, in case disconnected coal, pulse signal generator is connected and is started working, the firing pulse one control air valve, according to the impulse rate that sets in advance and a duration of ventilation length, penetrate high pressure draft to the canopy coal seam, destroy canopy coal seam arch, the coal seam is fallen.
