Description
Technical field
The present invention relates to coal yard mechanical field, particularly relate to oscillation device and method thereof that a kind of coal yard suppresses airborne dust and low-temperature oxidation.
Background technology
Coal resources in China storage is abundant, and yield increases year by year, and especially in recent years, along with the raising of mechanical coal mining degree, output constantly increased, and coal has become indispensable raw material and fuel in China's industrial production and people's lives.Present stage, China's energy-consuming was still based on coal, accounted for more than 78%, therefore, and being closely related smoothly of the safety in coal saving process and the development of the national economy.
Coal storage place is the place of leaving coal concentratedly.Produce in a large number at colliery, electric power, metallurgy, chemical industry, building materials, medicine, food etc., process, consume in the industry of coal, such all will be set and store place.The storage of coal generally can be divided into according to storage place: the various ways such as open-air storage, half open-air storage, indoor storage, wherein indoor storage has again the form such as silo, semi-underground warehouse.The place storing coal is concentrated in coal saving place, is present in coal production, transfer, accumulating, supply, use links.Such as steam power station usually will store the coal for power generation in skilful sky, and quantity can reach tens thousand of even tens0000 tons.
Coal, depositing in process, by air oxidation, causes coal varitation on the one hand, also can cause spontaneous combustion under certain condition on the other hand, cause huge economic loss, even the safety of entail dangers to personnel and facility.Estimate according to expert, in coal in China storage process, because windage loss, rain drop erosion loss, spontaneous combustion are lost and take care of the loss being not good at causing, reach more than 3,000 ten thousand tons every year, cause direct economic loss tens yuan.
In coal bunker, the airborne dust of coal dust not only causes economic loss but also contaminated environment.Low-temperature oxidation not only can cause the qualitative change of coal dust, and may also can spontaneous combustion, or even blast.
Prior art great majority adopt chemical agent to make coal dust fixed line, viscous; Also have and adopt biotechnology to prepare dust suppressant, form skin covering of the surface enclosed particles material; Also there are some power plant to adopt to close warehouse, only in warehouse, open a coal outlet.
(1) oscillation device of this suppression airborne dust and low-temperature oxidation have employed a kind of method of simple convenient operation again, utilizes the method for vibration to go to tamp coal dust.Compared with the method rolling coal dust, utilize vibration that coal dust can be made compacter, between spacing less.Do the spacing that both can reduce between coal storage like this and suppress poplar dirt, the air got rid of between coal storage suppresses low-temperature oxidation; The increasing cost that chemical agent and biotechnology can be avoided again to bring, the problem of contaminated environment, can also avoid it to the harm of human body.This method is compared with closed coal bunker, and advantage is that it can make the heat in warehouse distribute, and high temperature can not be caused to impel coal storage spontaneous combustion even to explode.
(2) excavator 1 in this device and rocking equipment thereof all can adopt electricity as driving force, have saved fuel resource and have reduced the pollution to environment.
(3) cable arrangements is peripheral in warehouse, and excavator 1, in its peripheral motion work, does like this and both can reach the object making coal dust compact and also can not affect this warehouse other operate normally; Also directly can install this device on the original base in warehouse, that is this device applicability is strong, is all suitable for and cost is lower for large small power plant.
(4) disk is equipped with in the lower end of oscillating rod, can increase the contact area of oscillation device and coal dust like this, and on the basis of oscillating rod, its compacting coal dust effect is better.
(5) excavator 1 has two kinds of functions, both can as compacting coal dust device, again can as getting device for coal.Utilize bucket wheel machine to get coal, then with belt-conveying on transport vehicle, recycling transport vehicle coal storage is transported to Pulverized Coal Bin.Integrate bucket wheel machine, belt conveyor, transport vehicle, reduce costs.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming above-mentioned prior art, the oscillation device providing a kind of simple and practical coal yard to suppress airborne dust and low-temperature oxidation and method thereof.
The present invention is achieved through the following technical solutions:
Coal yard suppresses an oscillation device for airborne dust and low-temperature oxidation, and what comprise the excavator 1 with cantilever and be arranged on excavator 1 fuselage rear gets device for coal, and the cantilever front end of described excavator 1 is provided with the oscillation device for tamping coal dust.
Described oscillation device comprises oscillating rod 4 and disk 5, and described oscillating rod 4 one end connects the cantilever of excavator 1, other end clutch disk 5.
The described bucket wheel 3 got device for coal and comprise belt conveyor 2 and be arranged on belt conveyor 2 end.
Described oscillation device is its power supply by the double cable 7 be arranged on around power plant warehouse 6.
The periphery of described bucket wheel 3 is dentalation.
Above-mentioned oscillation device is adopted to suppress the method for coal dust airborne dust and low-temperature oxidation as follows:
By the cantilever of excavator 1, stretch in coal dust by oscillating rod 4 and disk 5, be arranged on double cable 7 around power plant warehouse 6 for oscillating rod 4 and provide electric energy, oscillating rod 4 starts vibration and is tamped by coal dust, make coal dust compact airtight, thus suppress coal dust airborne dust and low-temperature oxidation.
