Abstract
The utility model discloses a coal drop pipe air injection dredging device which comprises an air supply device, a compressed air line, a plurality of spraying devices and an electrical control cabinet. The air supply device comprises an air compressor, an energy storage tank and a control valve. The compressed air line is connected with the air supply device and the spraying devices. The spraying devices comprise spraying pipes, spraying outlets and solenoid valves. The air supply device and the spraying devices are controlled by the electric control cabinet. The mode that compressed air is sprayed out abruptly is used to directly act on a jammed area, air pressure is converted into air-spray power energy immediately, and thus arching, bridging and jamming of raw coal particles are removed completely. The coal drop pipe air injection dredging device is the most ideal arch breaking, flow assisting and dredging device of a coal drop pipe currently, and is also suitable for blocking cleaning and dredging of blanking pipes of other industries.
Description
Technical field:
The utility model relates to a kind of dredger, is specifically related to a kind of coal spout air and sprays dredger.
Background technology:
The chute blockage phenomenon often appears in power plant boiler stokehold coal spout, cause boiler combustion unstable, be forced to carry out the banking fire blowing out or throw oil gun surely fire, main cause is that the stove raw coal is moist, moisture content is large, viscosity is large owing to entering, mix and burn coal slime, colm, and the coal spout design arrangement unreasonable, exist due to the fault of construction etc.Present solution mainly is that coal spout is carried out structure of modification and dredger is installed, carry out structure of modification exist long in time limit, need blowing out and effect undesirable, can not adapt to the shortcoming that the complexity of ature of coal coal changes; Mechanical dredger is installed, affected by front coal feeding system adverse circumstances, installing space and structure etc. larger and inapplicable; Adopt in addition air bubble is installed, because the big gun body is large, accessory is more, supporting leg and suspension ring need be installed, taken than large space, coal spout can not be arranged by multiple spot in same aspect, affect its dredging effect; And affected by the high-temperature dust particular surroundings, accessory is fragile, causes maintenance larger.
Summary of the invention:
The purpose of this utility model be to overcome the deficiencies in the prior art provide a kind of simple in structure, dredging is effective, the strong coal spout air of environmental suitability sprays dredger.
For achieving the above object, the technical solution of the utility model is:
A kind of coal spout air sprays dredger, and it is characterized in that: it comprises compressed air source unit, compressed air line, several injection apparatus, electrical control cubicles; Compressed air source unit comprises air compressor, energy storage tank and control valve; Compressed air line connects compressed air source unit and injection apparatus; Injection apparatus comprises playpipe, jet exit and magnetic valve; Compressed air source unit, injection apparatus are controlled by electrical control cubicles.
Described injection apparatus layering multiple spot, along around or be staggered in arrangement on coal spout.
The utility model beneficial effect is: the compressed air more than the 1MP that 1, is produced by compressed air source unit adopts after by energy storage the mode of suddenly ejection to directly act on and stops up the zone, moment can be transformed into the air-spray kinetic force with air pressure, and by PLC programme-control injection apparatus, thereby thoroughly eliminate former coal particle knot arch, put up a bridge and stop up.2, have that simple in structure, impulsive force is large, energy-saving safe, automatically control, be not subjected to installing space and running environment restriction, the various versions of adaptation coal spout, and do not damage the advantages such as body, be at present the most desirable coal spout broken arch, help stream, dredger, also be applicable to the block clearing dredging of other industry tremie pipe.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that injection apparatus of the present utility model is arranged schematic diagram along the principal plane around arrangement.
Fig. 3 is the principal plane layout schematic diagram that injection apparatus of the present utility model is staggered in arrangement mode.
Among the figure, 1. compressed air source unit, 2. compressed air line, 3. injection apparatus, 4. electrical control cubicles, 5. air compressor machine, 6. energy storage tank, 7. control valve, 8. playpipe, 9. magnetic valve, 10. jet exit, 11. coal spouts.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model is comprised of compressed air source unit 1, compressed air line 2, some injection apparatus 3 and electrical control cubicles 4.
Compressed air source unit 1 comprises air compressor machine 5, energy storage tank 6 and control valve 7, for injection apparatus 3 provides the compressed air gas source more than the pressure 1MP and passes through energy storage tank 6 storage air pressure energy.
Compressed air source unit 1, injection apparatus 3 are by electrical control cubicles 4 controls, and electrical control cubicles 4 is installed the PLC module, and the magnetic valve 9 of control injection apparatus 3 realizes that follow procedure erupts automatically.
As shown in Figure 2, injection apparatus 3 is by along around upper at coal spout 11 of arrangement.
As shown in Figure 3, injection apparatus 3 is by upper at coal spout 11 of stagger arrangement arrangement.
Operation principle:
The above high pressure air of 1MP that air compressor machine 5 produces is stored by energy storage tank 6; control valve 7 is opened during work; this moment, injection apparatus 3 was in the wait eruptivity; the knot arch occurs in the former coal particle in coal spout 11; when bridging and obstruction; operation electrical control cubicles 4 is to automatic mode; the magnetic valve 9 of each injection apparatus 3 successively starts by PLC module setting program; also can being set to manually, fixed point starts; at this moment; compressed air sprays suddenly through jet exit 10 from playpipe 8, makes air pressure moment be converted to the air-spray kinetic force, thereby produces powerful impulsive force; thoroughly eliminate coal spout 11 obstruction everywhere, make former coal particle recover to flow.
Claims (2)
