Abstract
A vertical single rotary raw coal bunker dredging device comprises a rotary bunker, a rotary support and a suspension support arm, and a serrated blade is arranged on the inner wall of the rotary bunker. The vertical single rotary raw coal bunker dredging device is characterized in that one side of the serrated blade close to a cylinder wall is in the shape of a blade point, and the other side of the serrated blade far away from the cylinder wall is serrated. One side of the serrated blade can be used for effectively scraping raw coal adhered on the wall of the rotary bunker and collapsing a foundation for arching in the bunker, the other side of the serrated blade functions in crushing and stirring coal briquettes formed due to factors such as gravity and moisture in the feeding process of the raw coal, the shortcoming of incapability of thoroughly removing blockage by one function of only collapsing arching is avoided, the inner side of the blade is serrated, and the problem of blockage of a feeding bunker section due to arching and caking of the raw coal is thoroughly solved under combined action of coal feeding gravity, friction force of coal particles, impact force of a rotary bunker cylinder and crushing force of the serrated blade.
Description
Technical field
The utility model relates to blockage-clearing device, especially relates to the blockage-clearing device of a kind of electricity power enterprise run coal bin.
Technical background
The run coal bin of existing thermal power generation corporations unit pulverized-coal system configuration, in coal-fired course of conveying, blanking section latch up phenomenon often appears, cause the boiler coal feeding amount uneven, combustion instability, the serious boiler flameout that causes, even unit outage bring serious potential safety hazard for the production of electricity power enterprise.The conical hopper place of position in storage discharging process of obstruction occurs.The major cause that causes run coal bin to stop up is: the raw coal quality is different, mixing of Winter Snow soil, in the motion of conical hopper blanking, be subjected to the effect of different directions power, the temperature rising is returned frost and is become moist shape, make coal-fired easily bonding, adhere on the hopper walls, make the blanking bin passage become narrow, under the constant prerequisite of raw coal flow velocity, form arch in the blanking bin section rapidly, result in blockage.South electricity power enterprise is in plum rain season, and because amount of rainfall is large, there was dampness in the air, and environment is abominable, and fire coal very easily bonds, wall built-up, and blanking is not smooth, the native mixing of coal, is the major cause that causes run coal bin to stop up.
At present, for solving coal blockage problem under the run coal bin, existing blockage-clearing device is asked the city, to be consisted of by revolution warehouse, pivoting support, suspention support arm, at revolution warehouse inwall one rooted tooth blade is set, although can effectively wipe the raw coal that is bonded on the bulkhead off, disintegrates the basis of knot arch in the storehouse, but can not in the blanking process, play fragmentation and beating action because of coal cinder that the factors such as gravity, humidity form to raw coal, can not thoroughly remove the drawback of obstruction.
The utility model content
The purpose of this utility model provides a kind of vertical single revolution run coal bin blockage-clearing device that can thoroughly solve blockage problem in the raw coal blanking process.
For achieving the above object, the utility model provides a kind of vertical single revolution run coal bin blockage-clearing device, comprise revolution warehouse, pivoting support, suspention support arm, at revolution warehouse inwall one rooted tooth blade is set, it is characterized in that: teeth cutter blade is knife edge shape near a side of barrel, is zig-zag away from the opposite side of barrel.
The utility model arranges a rooted tooth blade at the revolution bulkhead, and teeth cutter blade one side is knife edge shape, can effectively wipe the raw coal that is bonded on the bulkhead off, disintegrates the basis of knot arch in the storehouse; Opposite side is zig-zag, raw coal is played the effect of fragmentation and stirring because of the coal cinder of the factors such as gravity, humidity formation in the blanking process, avoided only disintegrating a kind of function of knot arch and bring can not thoroughly remove the drawback of obstruction, its cutter inboard is serration, friction force between lower coal gravity, coal particle, under the crushing force combined action of the impact of rotating cabin cylinder and serrated knife, thoroughly solved the blanking bin section blockage problem that raw coal knot arch, caking cause.
Description of drawings
Fig. 1 is structure cutaway view of the present utility model.
The specific embodiment
With reference to Fig. 1, the utility model comprises revolution warehouse 6, pivoting support 5, suspention support arm 7, at revolution warehouse inwall one rooted tooth blade 2 is set, and teeth cutter blade is knife edge shape near a side of barrel, is zig-zag away from the opposite side of barrel.Revolution warehouse upper end is connected with the warehouse 1 of storage warehouse section, and the lower end is connected with discharging opening warehouse 3, and the 4th, sealing member.
