Description
Technical field
The utility model relates to a kind of feeding device, particularly about the pulse-free coal powder supply device in a kind of pulverized-coal fired boiler.
Background technology
At present, feeding device in the tradition pulverized-coal fired boiler, generally be below the discharging opening of coal dust warehouse, the coal supply screw of one single head is set, end at the coal supply screw, be provided with one vertically downward material blanking tube and be connected with airduct, thereby by the wind-force in the airduct coal dust in the material blanking tube is blown in the boiler.The shortcoming of this feeding device is: coal supply powder pitch time is long, coal supply speed is slow and inhomogeneous, simultaneously because material blanking tube is vertically disposed, the feasible coal dust of sending in the airduct has the phenomenon of accumulation, be unfavorable in boiler furnace, blowing coal dust, cause the uneven problem of burning to occur in the boiler furnace.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of pulse-free coal powder supply device of boiler coal supply powder that can be quickly and evenly be.
For achieving the above object, the utility model is taked following technical scheme: a kind of pulse-free coal powder supply device is characterized in that: it comprises that a horizontally disposed conveying pipeline and is horizontally set on the airduct of described conveying pipeline below; The closed at both ends of described conveying pipeline, its upside near an end has an inlet point, and the downside of the close other end has a discharging opening; Described inlet point radially connects a storage bin, and described discharging opening radially connects a material blanking tube; The first half of described material blanking tube is vertical, and the latter half tilts towards the described conveying pipeline outside; Be provided with a feed spiral in the described conveying pipeline, an end of the close described discharging opening of described feed spiral connects the mouth of an electrical motor, and described electrical motor is fixed on the outside of described conveying pipeline; End near described electrical motor on the described conveying pipeline radially connects a stable-pressure device; One end of described airduct radially connects described material blanking tube, and the another port connects a blowing engine; The latter half of described material blanking tube is oblique to be connected in the described airduct, makes and forms an angle between the latter half of described material blanking tube and the described airduct; In described airduct, be provided with a Venturi tube structure with described material blanking tube junction; Also be provided with a control cock on the described airduct.
Angle between the latter half of described material blanking tube and the described airduct is arranged between 30 °～60 °.
Described control cock adopts Electric air valve.
The utility model is owing to take above technical scheme, it has the following advantages: 1, owing to the utility model material blanking tube is inclined to set, and and airduct between form an angle, therefore make whole coal chute road level and smooth, avoid the dead angle, prevented that effectively coal dust from piling up, stopping up and carry not smooth phenomenon in the coal chute road.2, because the utility model is provided with Venturi tube structure and stable-pressure device, in the pulverized coal conveying process, feed very fast evenly can be realized the purpose of continuous pulse free for powder, can not stop up.The utility model can be widely used in the small and medium-sized industrial coal powder boilers system or other storage powder-supply systems in.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises that a horizontally disposed conveying pipeline 1 and is horizontally set on the airduct 2 of conveying pipeline 1 below.
The closed at both ends of conveying pipeline 1, its upside near an end has an inlet point 3, and the downside of the close other end has a discharging opening 4.Inlet point 3 radially connects the discharging opening of a coal dust warehouse 5, and discharging opening 4 radially connects a material blanking tube 6.The first half of material blanking tube 6 is vertical, and the latter half tilts towards conveying pipeline 1 outside.Be provided with a feed spiral 7 in the conveying pipeline 1, an end of feed spiral 7 close discharging openings 4 connects the mouth of an electrical motor 8, and electrical motor 8 is fixed on the outside of conveying pipeline 1.End near electrical motor 8 on the conveying pipeline 1 radially connects a stable-pressure device 9, and stable-pressure device 9 can make pressure and the external atmosphere pressure in the conveying pipeline 1 keep basically identical, thereby realizes stable material-supplying.
One end of airduct 2 radially connects material blanking tube 6, and the another port connects a blowing engine 10.The latter half of material blanking tube 6 is oblique to be connected in the airduct 2, makes to form an included angle A between the latter half of material blanking tube 6 and the airduct 2, and this included angle A is greater than the slope angle of repose of coal dust, and operated by rotary motion is between 30 °～60 °.Be provided with a Venturi tube structure 11 with material blanking tube 6 junctions in airduct 2, its effect is to make coal dust after passing through Venturi tube structure 11, and it is more even to produce coal.Also be provided with a control cock 12 on the airduct 2, its effect is the wind supply quantity of regulating as required in the airduct 2, and in the present embodiment, what control cock 12 adopted is Electric air valve.
The utility model radially connects the discharging opening of coal dust warehouse 4 with the inlet point 3 of conveying pipeline 1 in use, and the outlet of airduct 2 is connected the burning installation of boiler.In the utility model when operation,, under the drive of electrical motor 8, feed spiral 7 rotations in the conveying pipeline 1 will be advanced coal dust in the conveying pipeline 1 by 5 inputs of coal dust warehouse, constantly deliver to the end of conveying pipeline 1, and fall in the material blanking tube 6.At this moment, because blowing engine 10 is blown by airduct 2, the coal dust that therefore falls into material blanking tube 6 falls under deadweight on the one hand, the drainage that is subjected to blast simultaneously falls, and enter in the Venturi tube structure 11, in airduct 2, under the wind effect, be delivered in the burning installation of boiler then.
The utility model only describes with the foregoing description; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
