Abstract
The utility model relates to a kind of blending bunker blockage-clearing device, including sequentially connected block clearing drill bit, flange, worm screw, worm gear, speed reducer, motor, the block clearing drill bit is located at the lower part of blending bunker；The block clearing drill bit is fixed on worm screw by flange, is driven by motor, along the vertical direction stroke action.Motor-driven Worm and worm-wheel gearing is utilized in the present apparatus, and suitable power output, the stroke action of control block clearing drill bit along the vertical direction are adjusted by speed reducer.It in the fluffy coal of blending bunker chute blockage, is dredged by block clearing drill bit, device simple possible, the method for comparing artificial block clearing, can reduce the amount of labour of operating worker, accelerated the block clearing time, ensure the normal operation of coal handling system.
Description
Technical field
The utility model relates to the coal mixing combustion mechanical equipments of power industry, and in particular to a kind of blending bunker blockage-clearing device.
Background technique
Country's coal price generally goes up at present, and coal-burning power plant is to reduce operating cost, often carries out coal from multiple places and adopts
Purchase.Coal mixing combustion be mixed according to a certain percentage according to variety classes, coal of different nature match after be sent into hearth combustion.It is substantially former
Reason is the ingredient using different types of coal, as requested, carries out reaching or approaching the coal finally allotted in performance with mixing disastrously
Boiler design coal requirement, so that boiler efficiency is high, power output is sufficient, environmental protection is good.What blending bunker was used to store single kind carrys out coal, when
When coal quality moisture is larger or air humidity is higher, frictional force increases between coal particle, between coal and coal scuttle wall, due to top coal
Weight form pressure, squeeze the more coal of moisture content and agglomerating generate fluffy coal and break coal.The method for generally using artificial block clearing, work
Make bad environments, block clearing ability is poor, and the amount of labour is big.
Utility model content
For the problem in existing production, the utility model provides a kind of blending bunker blockage-clearing device, structure is simple,
Reliable performance can effectively solve blending bunker blockage problem.
The utility model is to be achieved through the following technical solutions:
A kind of blending bunker blockage-clearing device, including sequentially connected block clearing drill bit, flange, worm screw, worm gear, speed reducer, motor,
The block clearing drill bit is located at the lower part of blending bunker；The block clearing drill bit is fixed on worm screw by flange, is driven by motor,
Stroke action along the vertical direction.
Further, the block clearing drill bit is that groove can be processed in cone or polyhedron shape, surface.
Further, the block clearing drill bit uses wear-resisting alloy steel.
Further, the worm screw uses steel alloy.
Further, the worm gear material uses gray cast iron.
Further, by flanged joint between the worm screw and block clearing drill bit, flange is high-strength by 6-12
Degree bolt is fixed.
Further, the speed reducer input terminal is connected to motor, and output end is connect with worm gear, can according to need tune
Revolving speed is saved, block clearing power output demand is met.
Compared with prior art, the utility model has the advantage that motor-driven worm and gear is utilized in the present apparatus
Transmission mechanism adjusts suitable power output, the stroke action of control block clearing drill bit along the vertical direction by speed reducer.It is stifled in blending bunker
When the fluffy coal of coal, dredged by block clearing drill bit, device simple possible, the method for comparing artificial block clearing can reduce operating worker
The amount of labour, accelerate the block clearing time, ensure the normal operation of coal handling system.
Detailed description of the invention
The present invention will be further described with example with reference to the accompanying drawing.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the integrally-built diagrammatic cross-section of the utility model；
Fig. 3 is the partial schematic diagram of the utility model；
Each label indicates in figure are as follows:
1- blending bunker, 2- worm screw, 3- worm gear, 4- speed reducer, 5- motor, 6- block clearing drill bit, 7- flange.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Figure 1-3, a kind of blending bunker blockage-clearing device, including sequentially connected block clearing drill bit 6, flange 7, worm screw 2, snail
3, speed reducer 4, motor 5 are taken turns, the block clearing drill bit is located at the lower part of blending bunker 1.
Blending bunker blockage-clearing device in the utility model is utilized motor 5 and is connect with speed reducer 4 to control the torque of output,
2 worm screw of worm gear, 3 transmission mechanism that speed reducer 4 drives, the stroke action of control block clearing drill bit 6 along the vertical direction.It is stifled in blending bunker 1
It when the fluffy coal of coal, is dredged by block clearing drill bit 6, device simple possible, can reduce the amount of labour of operating worker, when accelerating block clearing
Between, ensure the normal operation of coal handling system.
Preferably, block clearing drill bit 6 uses wear-resisting alloy steel.
Preferably, worm screw 2 uses steel alloy.
Preferably, 3 material of worm gear uses gray cast iron.
Preferably, it is connected between worm screw 3 and block clearing drill bit 6 by flange 7, flange 7 is fixed by 6-12 high-strength bolt.
Optionally, block clearing drill bit 6 is that groove can be processed in cone or polyhedron shape, surface.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, without deviating from the technical principle of the utility model, it can also do
Several improvements and modifications out, these improvements and modifications also should be regarded as the protection scope of the utility model.
