Abstract
The utility model relates to coal slime powder burning drying equipment, in particular to coal slime powder burn-back furnace equipment which comprises a roller dryer, a cyclone dust extractor communicated with the back end of the roller dryer, and a combustion furnace which is communicated with the front end of the roller dryer. A feeding hopper which is communicated with the roller dryer is arranged at the front end of the roller dryer. A discharge pipe is arranged on the lower portion of the cyclone dust extractor. The burn-back furnace equipment further comprises an air blower which is communicated with the combustion furnace through a conveying pipeline. Meanwhile, the discharge pipe is communicated with the conveying pipeline. The combustion furnace is a rotating type combustion furnace. According to a coal slime powder burn-back furnace, powder generated in the drying process of coal slime is completely removed, the purpose of environment protection is achieved, the coal slime powder burn-back furnace is only provided with two motors, total power is only 3.7 kilowatts, compared with a common heat source with the power of dozens of kilowatts, a large amount of electricity is saved, and drying cost is further lowered.
Description
Technical field
The utility model relates to a kind of coal slime powder burning drying equipment, is specifically related to a kind of coal slime powder furnace apparatus that flashes back.
Background technology
At present, also thereupon well sold and in short supply as the coal slime of coal industry deep processing byproduct along with the anxiety of coal resources, but because the coal slime moisture content is higher, must could use after drying.Therefore, the domestic systems that a lot of relevant coal slimes oven dry occurred can reduce the original moisture content of coal slime, take full advantage of this resource, turn waste into wealth.Thermal source is a vitals to whole system in coal slime drying system, and it directly affects the ruuning situation of whole system, if the thermal source cisco unity malfunction can cause whole system normally to move, incurs loss through delay and produces, and causes heavy losses.Thermal source that coal slurry drying-machine is joined originally has the multiple stoves such as fluidized bed furnace, chain grate furnace, it is exactly must consume a large amount of raw coal to act as a fuel that these thermals source have a common ground, if such fuel is not pulverized, directly can make burning insufficient with the bulk burning, the waste resource, as add reducing mechanism, consume again a large amount of electric energy.And no matter be coal-fired itself, or the electric energy that consumes all is a very large cost, these costs even affected the decision whether coal slime producer carries out this oven dry investment.Our company in the situation that the technical research theory and practice combine, invented the coal slime dust stove that flashes back, when the coal slime drying plant starts operation, begin to collect the coal slime dust in the cyclone dust removal discharger, utilize air blast to start coal dust is transported to the revolving combustor burning.The power of air blast is very little, and is very good through client's result of use, saves energy, and maintenance is few.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art and a kind of environmental protection is provided, and can save a large amount of electric energy, the coal slime powder that reduces the oven dry cost furnace apparatus that flashes back.
The purpose of this utility model is achieved in that a kind of coal slime dust furnace apparatus that flashes back, comprise roller drying machine, the cyclone dust collectors that are communicated with the roller drying machine rear end, the combustion furnace that is communicated with the roller drying machine front end, described roller drying machine front end is provided with the feed hopper that is communicated with it, described cyclone dust collectors bottom is provided with discharge duct, this furnace apparatus that flashes back also comprises an air blast, described air blast is communicated with combustion furnace by conveyance conduit, simultaneously, described discharge duct is communicated with conveyance conduit, and described combustion furnace adopts revolving combustion furnace.
The bottom of described revolving combustion furnace is equipped with sliding rail, and described combustion furnace slides by the movable pulley of its underpart.
The utlity model has following advantage:
1, the coal slime dust of the present invention stove that flashes back, the dust that has produced when fully having consumed the coal slime oven dry has reached the purpose of environmental protection.
2, the coal slime dust of the present invention stove that flashes back will be used a small amount of fire coal during except first time installation and debugging, need not feed coal in the later activity in production, and a dust that only utilizes oven dry to produce gets final product as combustion material, has greatly saved the oven dry cost.
3, the coal slime dust of the present invention stove that flashes back only has two motors, and general power only has 3.7kw, compared with general thermal source tens kilowatts power easily, has saved a large amount of electric energy, and another has reduced the oven dry cost.
4, the coal slime dust of the present invention stove that flashes back is simple in structure, easy to maintenance.

Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation of rotary burner.Fig. 4 is the right TV structure schematic diagram of Fig. 3.
The specific embodiment
The utility model will be further described below in conjunction with concrete embodiment.
Such as Fig. 1,2,3, shown in 4, a kind of coal slime dust furnace apparatus that flashes back, comprise roller drying machine 2, the cyclone dust collectors 4 that are communicated with roller drying machine 2 rear ends, the combustion furnace 1 that is communicated with roller drying machine 2 front ends, described roller drying machine 2 front ends are provided with the feed hopper 5 that is communicated with it, described cyclone dust collectors 4 bottoms are provided with discharge duct 4.1, it is characterized in that: this furnace apparatus that flashes back also comprises an air blast 3, described air blast is communicated with combustion furnace 1 by conveyance conduit 6, simultaneously, described discharge duct 4.1 is communicated with conveyance conduit 6, and described combustion furnace 1 adopts revolving combustion furnace.
The bottom of described revolving combustion furnace 1 is equipped with sliding rail 7, and described combustion furnace 1 slides by the movable pulley 8 of its underpart.
Structure of the present utility model is as follows: described coal slime dust flashes back stove by revolving combustor, be used to provide the combustion space, drying drum, continuous rotation in service, at the lower dry materials of the effect of drying medium, air blast is carried the coal slime dust in the revolving combustor by conveyance conduit, cyclone dust collectors, the coal slime dust separation in the roller drying machine out.
