Description
Technical field
The utility model relates to the subdividing device of a kind of garbage derivatived fuel (RDF), is specifically related to a kind of RDF aidr bells blast system.
Background technology
Although existing garbage comprehensive treatment technology is of a great variety, sum up its basic fundamental route all: first sorting, then classifies sorting thing to carry out integrated treatment.China's municipal garbage mostly is mixed collection, and crude waste is with the perishable organic matter of many high-moistures, and as dish skin melon and fruit, kitchen excess etc., they are together with the mutual viscous such as polybag, glass, metal and brick and tile gravel.If the rubbish of existing these humidities of sorting machine sorting and viscous is difficult to prove effective, in the situation of haveing no alternative but, can only select simple screening and artificial separation operation.
At present, widely used pneumatic separator is mainly that the feed separation of the different unit weights in house refuse is become to several different compositions, and belong to heavy substance for the organic matter of post-processed, a kind of wind speed is difficult to meet the material sorting requirement of several different unit weights, therefore the efficiency of separation of this kind of winnowing machine is not high, often that several compositions are intertwined, and this kind of winnowing machine uses circulated air, the a small amount of large particle diameter rubbish of bringing in wind is wrapped on the impeller of blower fan, blower fan is broken down, cause selection by winnowing efficiency low, the problems such as plant maintenance difficulty.
Utility model content
The purpose of this utility model is to provide a kind of RDF aidr bells blast system, and this system sorting efficiency is high, effectively the heavy substance in the house refuse after precrushing of separation and dry processing.
A kind of RDF aidr bells blast system, it is characterized in that: the belt feeder that comprises at least three head and the tail interval docking in closure casing, and the belt feeder that is positioned at front end is tilted to and is arranged so that on the unsettled tail wheel that is positioned at another belt feeder of the great wheel of this belt feeder, the great wheel that another belt feeder is tilted to setting and another belt feeder is positioned on the tail wheel of finished belt machine; Between the belt feeder great wheel of front end and another tail pulley of belt conveyor, horizontal interval arranges, and interval arranges a nozzle, described nozzle wind-force is towards oblique upper, and making to transport from the belt feeder of front end the lightweight RDF getting off can be blown on another belt feeder by nozzle;
Under the belt feeder great wheel of front end and another tail pulley of belt conveyor interval joint, weight collection bucket is set, makes to transport from the belt feeder of front end the RDF weight composition getting off and fall into this weight collection bucket;
At belt feeder great wheel and another tail pulley of belt conveyor interval joint of front end, the air outlet that housing setting is connected with airduct, the airduct other end connects bag filter and chimney in turn.
By technique scheme, the angle adjustable belt feeder of another belt feeder for regulating according to the character of RDF material.
By technique scheme, dust-precipitator blower fan is connected with bag filter, and the import of chimney is arranged between dust-precipitator blower fan and bag filter.
By technique scheme, nozzle is connected with frequency conversion fan.
By technique scheme, described lightweight RDF comprises finished product RDF and lightweight stone or lightweight dust particle, and described RDF weight composition comprises bulk stone or pouring weight dust.
With respect to prior art, the aidr bells blast system sorting material of the utility model design is clearer and more definite, only sub-elect the stone in RDF material, like this can be by regulating the wind speed of nozzle and the adjustment of belt feeder angle to realize higher separating effect, in addition, the selection by winnowing that the design uses has been used bag filter, and the dust-collecting efficiency of bag filter is high, the problem that had so both solved rubbish winding blower fan, also can prevent dusty gas atmosphere pollution.
