Description
Technical field
The present invention relates to coal yard mechanical field, more particularly to a kind of coal yard suppress airborne dust and low-temperature oxidation oscillation device and
Its method.
Background technology
Coal resources in China storage is abundant, and yield increases year by year, especially in recent years, with mechanical coal mining degree
Improve, yield constantly increases, and coal has turned into indispensable raw material and fuel in China's industrial production and people's lives.Existing rank
Section China energy-consuming accounts for more than 78% still based on coal, therefore, the safety during coal saving is built with national economy
If be smoothed out be closely related.
Coal storage place is the place for leaving coal concentratedly.It is big in colliery, electric power, metallurgy, chemical industry, building materials, medicine, food etc.
In amount production, processing, the industry of consumption coal, such storage place will be set.The storage of coal is general according to storage place
Can be divided into:The diversified forms such as open-air storage, half open-air storage, indoor storage, wherein indoor storage have silo, semi-underground warehouse again
Etc. form.Coal saving place be concentrate storage coal place, be present in coal production, transfer, accumulating, supply, using each
Individual link.Such as thermal power plant is often required to store the coal for power generation in skilful day, and quantity is up to tens thousand of or even ten tens of thousands of tons.
Coal, by air oxidation, on the one hand causes coal varitation, on the other hand under certain condition during storage
Spontaneous combustion can also be caused, huge economic loss is caused, in addition entail dangers to personnel and facility safety.Estimated according to expert, at me
During state's coal saving, the loss caused by windage loss, rain drop erosion loss, spontaneous combustion loss and keeping are not good at reaches every year
More than 30000000 tons, cause tens yuan of direct economic loss.
The airborne dust of coal dust not only causes economic loss but also pollutes environment in coal bunker.Low-temperature oxidation not only results in coal dust
Qualitative change, and may can also spontaneous combustion, even explode.
The content of the invention
A kind of shortcoming and defect it is an object of the invention to overcome above-mentioned prior art, there is provided simple and practical coal yard suppression
The oscillation device and its method of airborne dust processed and low-temperature oxidation.
The present invention is achieved through the following technical solutions：
A kind of coal yard suppresses the oscillation device of airborne dust and low-temperature oxidation, including the excavator 1 with cantilever and is arranged on digging
The fuselage rear of native machine 1 takes device for coal, and the cantilever front end of the excavator 1 is provided with the oscillation device for tamping coal dust.
The oscillation device includes oscillating rod 4 and disk 5, and the one end of the oscillating rod 4 connects the cantilever of excavator 1, another
End clutch disk 5.
It is described to take device for coal including belt conveyor 2 and be arranged on the bucket wheel 3 of the end of belt conveyor 2.
The oscillation device is its power supply by the double cable 7 being arranged on around power plant warehouse 6.
The periphery of the bucket wheel 3 is dentalation.
The method for suppressing coal dust airborne dust and low-temperature oxidation using above-mentioned oscillation device is as follows：
By the cantilever of excavator 1, during oscillating rod 4 and disk 5 stretched into coal dust, it is arranged on around power plant warehouse 6
Double cable 7 is that oscillating rod 4 provides electric energy, and oscillating rod 4 starts to vibrate and tamp coal dust, makes coal dust compact airtight, from
And suppress coal dust airborne dust and low-temperature oxidation.
The present invention at least has the following advantages that and effect relative to prior art：
Most of prior art is to make coal dust fixed line, viscous using chemical agent；Also have and dust suppression is prepared using biotechnology
Agent, forms surface membrane closure particulate matter；Also it is, using closing warehouse, a coal outlet only to be opened in warehouse to have some power plant.
(1) oscillation device of this suppression airborne dust and low-temperature oxidation employs method that is a kind of simple and being easy to operation, utilizes
The method of vibration goes to tamp coal dust.Compared with the method for rolling coal dust, using vibration coal dust can be made more compact, between spacing
It is smaller.The spacing that do so can both reduce between coal storage suppresses poplar dirt, and the air excluded between coal storage suppresses low-temperature oxidation；Again
Increasing cost, the problem of pollution environment that chemical agent and biotechnology are brought can be avoided, it can also be avoided to human body
Harm.Compared with coal bunker is closed, advantage is that it can distribute the heat in warehouse to this method, will not cause height
Temperature promotes coal storage spontaneous combustion even to explode.
(2) excavator 1 and its rocking equipment in the device can save fuel resource simultaneously using electricity as driving force
And pollution of the reduction to environment.
(3) in warehouse periphery, in its periphery motion work, do so can both reach makes coal dust to excavator 1 to cable arrangements
Compact purpose does not interfere with other normal operations of the warehouse yet；This directly can also be installed on the original base in warehouse
Device, that is to say, that the device strong applicability, is all suitable for for big small power plant and cost is relatively low.
(4) lower end of oscillating rod is equipped with a disk, can so increase the contact area of oscillation device and coal dust, is shaking
Swing on the basis of rod, its compacting coal dust is better.
(5) excavator 1 possesses two kinds of functions, both can be as the device of stamped coal powder, again can be as taking device for coal.Profit
Coal is taken with bucket wheel machine, then with belt-conveying to transport vehicle, coal storage transport is arrived Pulverized Coal Bin by recycling transport vehicle.Collection bucket wheel
Machine, belt conveyor, transport vehicle are integrated, reduces cost.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is that cable run arranges schematic diagram.
Specific embodiment
The present invention is more specifically described in detail with reference to specific embodiment.
Embodiment
As shown in Figure 1, 2.Coal yard of the present invention suppresses the oscillation device of airborne dust and low-temperature oxidation, including the shoveling with cantilever

Oscillation device.
The oscillation device includes oscillating rod 4 and disk 5, and the one end of the oscillating rod 4 connects the cantilever of excavator 1, another
End clutch disk 5.
It is described to take device for coal including belt conveyor 2 and be arranged on the bucket wheel 3 of the end of belt conveyor 2.The bucket wheel 3
Periphery is dentalation.
The oscillation device is its power supply by the double cable 7 being arranged on around power plant warehouse 6.
Excavator 1, using electricity as its power, in the periphery motion in warehouse, so neither influences other ground by cable 7
Upper normal operation, it is not required that spatially add complex appts, effect pattern at it.
Be put into coal dust for oscillating rod 4 and disk 5 by the cantilever of excavator 1, and coal dust is tamped with the mode of vibration, by controlling to dig
Native machine 1 can adjust the length and depth of put oscillating rod 4 and disk 5.Device for coal is taken, bucket wheel 3 takes coal dust from warehouse
Go out, coal dust is sent into cable by belt conveyor 2 vibrates in the compartment of car, so can be achieved with taking coal, coal storage, transport coal
Function.
