Abstract
The utility model discloses a coal bucket coal injection device, comprising a coal bucket, a compressed air source and an exhaust injection pipe respectively connected with the coal bucket and a compressed air tank, wherein a metal pipeline connected with the compressed air source is arranged outside and around the coal bucket, one end of the exhaust injection pipe is in serial connection with the metal pipeline, and the other end of the exhaust injection pipe extends into the coal bucket. The coal bucket coal injection device has the advantages of strong blockage eliminating efficacy and low investment cost.
Description
Technical field
The utility model relates to a kind of coal bunker and blows device for coal.
Background technology
Thermal power plant's raw coal material-falling hopper is that coal handling system is carried coal-fired visual plant to boiler combustion system.Its planform is basic identical, and top is conical, and the bottom is a rectangle.Suitable for reading big, following young, charging suitable for reading, raw coal falls by deadweight from top to bottom.The following raw coal that falls behind enters coal mill by feeder, finally delivers to combustion chamber.In actual moving process, the blanking blockage problem that this equipment ubiquity is serious.After stopping up, can bring by coal bunker operation to shut down or waste serious consequences such as heavy oil.
Usually the scheme that solves is to install the special material liner additional at the run coal bin inwall, but this scheme effect in actual use is unsatisfactory, and have the following disadvantages: when 1) big slightly or coal changes in raw coal humidity, chute blockage is arranged still the time behind liner macromolecule plate or the stainless steel sheet, especially containing ash when more or relatively moister, 2 when raw coal) investment of liner scheme is bigger.
The utility model content
At the deficiencies in the prior art, the utility model provides the strong coal bunker of a kind of block clearing effectiveness to blow device for coal, and this device utilizes pressurized air that the coal of blocking in the coal bunker is blown pine, thereby has avoided the obstruction of coal bunker.
In order to achieve the above object, the utility model adopts following technical scheme:
Coal bunker blows device for coal, comprise coal bunker, compressed air tank and the exhaust jet pipe that is connected with compressed air tank with coal bunker respectively, described coal bunker is provided with a metallic conduit that joins with compressed air source outward, this metallic conduit is around the coal bunker setting, described exhaust jet pipe one end is connected in series with above-mentioned metallic conduit, and the other end stretches in the coal bunker.
Further, the described exhaust jet pipe quantity that is connected in series with metallic conduit is 8, forms an octagon.
Further, four jet being directed upwardly of exhaust jet pipe wherein, all the other four jet directions of exhaust jet pipe are down.
Further, described metallic conduit is some, respectively around the coal bunker setting.
Further, the nozzle of described jet up exhaust jet pipe is cylindrical, and its outer rim is provided with a breach; Described jet down exhaust jet pipe nozzle is cylindrical, and its outer wall is provided with two perforates.
Further, described coal bunker outer wall is provided with opening, and described exhaust jet pipe stretches in the coal bunker in opening.
The beneficial effects of the utility model are: 1, block clearing is renderd a service strong; 2, cost of investment is low.

Below in conjunction with specific embodiment the utility model is described further:
The specific embodiment
As shown in Figure 1, it is conical that coal bunker described in the utility model 1 top is, and the bottom is rectangular.Described coal bunker bottom along rectangle coal bunker outer wall, is provided with first metallic conduit 11, and one end and compressed air source join, and the other end is connected in series with the exhaust jet pipe.Described coal bunker top along conical outer wall, is provided with second metallic conduit 12 and the 3rd metallic conduit 13, and one end and compressed air tank join, and the other end is connected in series with the exhaust jet pipe.Because the utility model compressed air tank distance is far away, does not illustrate among the figure.
As shown in Figure 2, be serially connected with eight exhaust jet pipes successively on the described ground metallic conduit 11, form an octagon, four jet being directed upwardly of exhaust jet pipe wherein, all the other four jet directions of exhaust jet pipe are down.The nozzle of four wherein jet up exhaust jet pipes is an A type nozzle 2, and the nozzle of four jet down exhaust jet pipes is a Type B nozzle 3, and described A type nozzle 2 is provided with successively at interval with Type B nozzle 3.
As shown in Figure 4, described A type nozzle 2 is cylindrical, and its outer rim is provided with a breach 21, is used for preventing that cinder from falling into nozzle.
Shown in Fig. 5-6, described Type B nozzle 3, its outer wall is provided with perforate 31.
As shown in Figure 3, described second metallic conduit 12 is identical with the exhaust jet pipe that exhaust jet pipe on the 3rd metallic conduit 13 is arranged on first metallic conduit 11.Do not repeat them here.
Further, the coal bunker outer wall is provided with opening, and described exhaust jet pipe stretches in the coal bunker in opening.
Further, be equipped with air inlet valve on the described metallic conduit.
During use, open the air inlet valve on the metallic conduit, the pressurized air in the compressed air tank goes out through exhaust jet pipe nozzle ejection, blows coal downward or upward, prevents to stop up.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
