Abstract
The invention relates to an RDF (Refuse Derived Fuel) winnowing system which is characterized in that at least three belt conveyors, which are butted end to end at intervals, are arranged inside a closed housing; the belt conveyor at the front end is inclined upwards so that a head wheel of the belt conveyor is suspended above a tail wheel of the second belt conveyor; the second belt conveyor is inclined upwards, and a head wheel of the second belt conveyor is positioned on a tail wheel of the finished product belt conveyor; the head wheel of the belt conveyor at the front end and the tail wheel of the second belt conveyor are arranged horizontally at an interval; a nozzle is arranged at the interval; a heavy material collecting hopper is arranged under the interval joint of the head wheel of the belt conveyor at the front end and the tail wheel of the second belt conveyor; an air outlet connected with a wind pipe is formed in the housing in a position corresponding to the interval joint of the head wheel of the belt conveyor at the front end and the tail wheel of the second belt conveyor at the interval; the other end of the wind pipe is connected with a bag type dust collector and a chimney in sequence. The RDF winnowing system provided by the invention has the advantages that material sorting is relatively explicit, that is, only stones in RDF materials can be sorted out; a higher separating effect can be achieved by adjusting the wind speed of the nozzle and the angles of the belt conveyors; pollution to atmosphere caused by dusty gas can be prevented.
Description
Technical field
The present invention relates to the subdividing device of a kind of garbage derivatived fuel (RDF), be 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 sorting thing is classified and 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 and polybag, glass, metal and brick and tile gravel etc. are mutually together with viscous.If these moist and rubbish of viscous of existing sorting machine sorting are difficult to prove effective, in the situation of haveing no alternative but, simple screening and artificial separation operation can only be selected.
At present, the feed separation of the different unit weights in house refuse is mainly become several different composition by widely used pneumatic separator, and belong to middle heavy substance for the organic matter of post-processed, a kind of wind speed is difficult to the material sorting requirement meeting several different unit weight, therefore the efficiency of separation of this kind of winnowing machine is not high, often that several composition is intertwined, and this kind of winnowing machine uses circulated air, the a small amount of Large stone rubbish brought 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.
Summary of the invention
The object of the present invention is to provide a kind of RDF aidr bells blast system, this system sorting efficiency is high, effectively can be separated the heavy substance in the house refuse after precrushing and dry process.
A kind of RDF aidr bells blast system, it is characterized in that: the belt feeder comprising at least three head and the tail interval docking in closure casing, and the belt feeder being positioned at front end tilts upward and is arranged so that on the unsettled tail wheel being positioned at another belt feeder of the great wheel of this belt feeder, another belt feeder tilts upward setting and the great wheel of 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 is arranged, 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 got off can be blown on another belt feeder by nozzle;
Immediately below 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 got off and fall into this weight collection bucket;
Belt feeder great wheel in front end and another tail pulley of belt conveyor interval joint, housing arranges the air outlet be connected with airduct, and the airduct other end connects bag filter and chimney in turn.
By technique scheme, another belt feeder is carry out according to the character of RDF material the angle adjustable belt feeder that regulates.
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.
Relative to prior art, the aidr bells blast system sorting material of the present invention's design is clearer and more definite, only sub-elect the stone in RDF material, higher separating effect can be realized like this by regulating the wind speed of nozzle and the adjustment of belt feeder angle, in addition, the selection by winnowing that the design uses employs bag filter, and the dust-collecting efficiency of bag filter is high, so both solve the problem that rubbish is wound around blower fan, also can prevent dusty gas atmosphere pollution.

Detailed description of the invention
The RDF aidr bells blast system that the present invention relates to, it is characterized in that: the belt feeder comprising at least three head and the tail interval docking in closure casing, and the belt feeder 11 being positioned at front end tilts upward and is arranged so that on the unsettled tail wheel being positioned at another belt feeder of the great wheel of this belt feeder 11, another belt feeder tilts upward setting and the great wheel of 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 is arranged, and interval arranges a nozzle 1, described nozzle 1 wind-force is towards oblique upper, and making to transport from the belt feeder 11 of front end the lightweight RDF got off can be blown on another belt feeder by nozzle 1;
Immediately below the belt feeder great wheel of front end and another tail pulley of belt conveyor interval joint, weight collection bucket 3 is set, makes to transport from the belt feeder 11 of front end the RDF weight composition got off and fall into this weight collection bucket 3;
Belt feeder great wheel in front end and another tail pulley of belt conveyor interval joint, housing arranges the air outlet be connected with airduct 6, and airduct 6 other end connects bag filter 7 and chimney 9 in turn.
By technique scheme, another belt feeder is angle adjustable belt feeder 5, and angle can regulate according to the character of RDF material.
