Abstract
The utility model discloses a powdery material unloading device, which relates to an unloading device which conveys coal dust to a coal dust bin and a powder conveying auger in a boiler powder making system. The powdery material unloading device comprises a vertical short joint pipe butted with a coal dust screen unloading pipe, a coal dust bin unloading inclined pipe and a material conveying auger unloading inclined pipe. The utility model is characterized in that the powdery material unloading device further comprises an auxiliary coal dust bin unloading pipe which is arranged on the lower side of the material conveying auger unloading inclined pipe and is in parallel with the material conveying auger unloading inclined pipe; one end of the auxiliary coal dust bin unloading pipe is communicated and fixedly connected with the coal dust bin unloading inclined pipe, while the other end thereof is communicated and fixedly connected with a vertical extended pipe of the material conveying auger unloading inclined pipe. The device of the utility model effectively changes the phenomenon that the powder unloading device of the conventional power preparation system causes large deviation between the powder positions on the two sides of the coal dust bin, reduces the powder position difference, stabilizes the boiler combustion and has simple structure, reliable working performances, small maintenance load and low manufacturing cost.
Description
Technical field
A kind of granular material blanking device relates to the blanking device that a kind of boiler milling system pulverized coal conveying carries out coal dust feed bin and defeated powder auger.
Background technology
Bin system in the middle of the coal ash of heating power factory coal burning boiler is supplied with usually employing.Coal dust enters tremie pipe through the screening of sifting out, and enters the coal dust feed bin or enters defeated powder auger through blanking device.At present, the structure of granular material blanking device comprises: a vertical pipe nipple pipe that docks with the pulverized coal sieve tremie pipe, pipe nipple pipe lower end is provided with two discharging openings, one of them outlet is connected with the oblique Pulverized Coal Bin blanking inclined tube that stretches to the outside, upper outlet is connected with the oblique conveyer device﹠apos blanking inclined tube that stretches to the outside in addition, Pulverized Coal Bin blanking inclined tube discharging opening is positioned at Pulverized Coal Bin, and conveyer device﹠apos tremie pipe discharging opening docks with conveyer device﹠apos, and pulverized coal sieve outlet pipe place is equipped with down the powder diversion baffle.The adjusting of powder diversion baffle can enter Pulverized Coal Bin and also can enter defeated powder auger under the isolated qualified coal dust process of pulverized-coal collector.Enter Pulverized Coal Bin by tube cell under the Pulverized Coal Bin under the normal circumstances, because the Pulverized Coal Bin cross-sectional plane is partial to Pulverized Coal Bin one side than the installation site of tube cell under big and the Pulverized Coal Bin, cause powder position, Pulverized Coal Bin both sides overbalance, drop can reach two meters.Low or form the low side machine supplying powder in powder position when falling powder easily and come that powder is bad to influence boiler smooth combustion in the powder position.For the influence that reduces powder position drop just needs to keep Gao Fenwei, so the increase of ball grinding mill start-stop time, cause the powder process power consumption to increase.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, a kind of simple in structure, reliable working performance is provided, maintenance capacity is little, cost is low, can effectively solve the low phenomenon in a high side powder position, Pulverized Coal Bin one side powder position, machine supplying powder normally comes powder, stablize boiler combustion, reduce the granular material blanking device of powder process power consumption.
The purpose of this utility model is achieved through the following technical solutions.
A kind of granular material blanking device, its structure comprises: a vertical pipe nipple pipe that docks with the pulverized coal sieve tremie pipe, pipe nipple pipe lower end is provided with two discharging openings, one of them outlet is connected with the oblique Pulverized Coal Bin blanking inclined tube that stretches to the outside, upper outlet is connected with the oblique conveyer device﹠apos blanking inclined tube that stretches to the outside in addition, Pulverized Coal Bin blanking inclined tube discharging opening is positioned at Pulverized Coal Bin, and conveyer device﹠apos tremie pipe discharging opening docks with conveyer device﹠apos, and screen outlet pipe place is equipped with down the powder diversion baffle; It is levied and is also to comprise in its structure:
Pulverized Coal Bin blanking looped pipeline-this blanking looped pipeline is positioned at conveyer device﹠apos tremie pipe downside, parallel with the conveyer device﹠apos tremie pipe, and an end communicates affixed with Pulverized Coal Bin blanking inclined tube, and an end communicates affixed with the vertical pipe that prolongs of conveyer device﹠apos tremie pipe.
Device of the present utility model has changed effectively that the powder device causes the big phenomenon of powder level in coal powder banker both sides deviation under original pulverized coal preparation system, has reduced the powder potential difference, has stablized boiler combustion.It is simple in structure, reliable working performance, maintenance capacity is little, cost is low.Thoroughly solved the low phenomenon in a high side powder position, Pulverized Coal Bin one side powder position.Can both guarantee well that machine supplying powder normally comes powder when no matter hanging down the powder position or falling powder, stablize boiler combustion.The ball grinding mill start-stop time reduces, and the powder process power consumption obviously reduces.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of granular material blanking device, its structure comprises: a vertical pipe nipple pipe 2 that docks with pulverized coal sieve 1 tremie pipe, pipe nipple pipe lower end is provided with two discharging openings, one of them outlet is connected with the oblique Pulverized Coal Bin blanking inclined tube 3 that stretches to the outside, upper outlet is connected with the oblique conveyer device﹠apos blanking inclined tube 4 that stretches to the outside in addition, Pulverized Coal Bin blanking inclined tube discharging opening is positioned at Pulverized Coal Bin 5, and conveyer device﹠apos tremie pipe discharging opening docks with conveyer device﹠apos 6, and screen outlet pipe place is equipped with down powder diversion baffle 7; Its structure comprises that also this blanking looped pipeline of Pulverized Coal Bin blanking looped pipeline 8-is positioned at conveyer device﹠apos tremie pipe downside, parallel with the conveyer device﹠apos tremie pipe, and an end communicates affixed with Pulverized Coal Bin blanking inclined tube, and an end communicates affixed with the vertical pipe that prolongs of conveyer device﹠apos tremie pipe.
Tube cell links a kind of granular material blanking device of the present utility model under pipeline that rational position and suitable openings draw a suitable degree of dip and the defeated powder auger getting on the tube cell under original Pulverized Coal Bin, guarantee that the isolated qualified coal dust of pulverized-coal collector on average enters Pulverized Coal Bin through two following tube cells, thereby make Pulverized Coal Bin powder position balance everywhere.Avoid managing interior accumulated powder for the following powder that guarantees equalizing pipe is smooth and easy and stop up, equalizing pipe must guarantee certain degree of dip, is not less than 40 degree in principle.
