Description
Technical field
It is exactly specifically to be related to for by coal crusher and wearing into the coal of coal dust and grinding the present invention relates to material grinding equipment
Machine, arranged more particularly, to the coal mill dreg discharging box that can improve waste residue organic efficiency and reduction coal mill residue contamination environment degree
Cinder notch sealing structure.
Background technology
As economical activities of mankind continues to develop, food and clothing lives base substance condition of four aspects of row as human survival,
Along with the continuous development of scientific and technological level, further raising has also been obtained, people not only to be eaten full in terms of eating,
That also to be eaten good, the health eaten；Aspect firmly is from the basic demand taken shelter from rain of keeping out the wind, the firm, safety that becomes that requirement lives and comfortable；
Wear the clothes and increasingly pursue colourful, pass everyone individual character, and the major advance of row embodies on a vehicle, people
Walked from original by pin, develop into bicycle, later automobile, aircraft, or even people till now take spaceship
Tourism, all embodies the improvement that the progress of scientific and technological level is lived to people.
The progress of science and technology is brought to mankind itself also causes extremely serious destruction, people to environment while great convenience
Class directly or indirectly exceedes the material or energy of its self-purification capacity to environmental emission, so that the quality of environment reduces, to people
The phenomenon that the survival and development, the ecosystem and the property of class adversely affect.Specifically include：Water pollution, atmosphere pollution, noise
Pollution, radioactive pollution etc..With the development of scientific and technological level and the raising of living standards of the people, environmental pollution is also increasing
Add, particularly in developing country.Problem of environmental pollution increasingly becomes one of common issue of world's every country.Environment is dirty
Dye can cause directly to destroy and influence to the ecosystem, such as：Desertification, forest deterioration, between also being caused to human society
The harm connect, the hazard ratio of sometimes this indirect environmental effect at that time caused by directly harm it is bigger, be also more difficult to eliminate.
In many factors for causing environmental pollution, the burning of fossil energy is a major reason, especially fossil energy
In coal burning, the burning of coal can produce waste gas, waste residue causes greatly to destroy to environment, but current economic life
The use of coal temporarily can not possibly be also fully phased out, then, people just reduce coal burning to environment under existence conditions as possible
Pollution and destruction, by coal grinding after-combustion improve coal combustion rate be reduce coal burning produce pollution one it is important
Method.At present, coal grinding is used into coal mill, coal mill is by coal crusher and wears into the machinery of coal dust, and it is coal
The important auxiliary equipment of powder stove.Coal-grinding process is that coal is broken and its ever-increasing process of surface area.Increase new surface
Product, it is necessary to overcome the adhesion between molecular solids, thus need consumed energy.Coal is milled into coal dust in coal pulverizer, mainly
Carried out by crushing, smashing and grinding three kinds of modes, wherein the energy of crushing process consumption most saves.Grinding process most takes energy,
Various coal mills all have two or three above-mentioned of mode concurrently in pulverizing process.Coal mill needs continuous deslagging to protect at work
The normal work of coal mill is demonstrate,proved, but existing traditional deslagging tank mounting structure is not easy to grind because coal contains impurity, with
And cinder is directly easily deposited in being produced to slag-drip opening for dreg discharging box outlet and blocked, the cinder for being blocked in slag-drip opening tires out for a long time
Product, spontaneous combustion, explosion accident easily occurs, not only have impact on the operating efficiency and service life of coal mill, while be also easy to occur
Security incident.
Chinese Patent Application No. 200620089196.7 discloses a kind of miller residue discharging device, including slag-drip opening, support body, row
