It further, further include being mixed with the feed inlet seal closure of mixing machine cylinder feed inlet face face sealing, with described
The discharge port seal closure of conjunction machine cylinder discharge port face face sealing and the belt dust sealed with feed inlet sealing cover face are received
Collection cover；It is straight that the discharge end of the mixture conveyor belt sequentially passes through the belt dust collection cover, the feed inlet seal closure
Extremely it is connected with the mixing machine cylinder feed inlet；One end of the one mixed technique filler pipe and the dedusting water pipe both passes through described
Discharge port seal closure is until protrude into the mixing machine cylinder interior；At least one described deduster passes through the cleaning shaft and institute
Discharge port seal closure upper end is stated to be connected.
Further, the deduster is two, accesses the cleaning shaft and the blower after two duster parallels
Between.
Compared with prior art, the utility model has the advantage that
1, feed inlet of the negative pressure that the utility model mixing machine high-efficiency dust removal system utilizes blower to generate in mixing machine cylinder
One flue gas stream is formed to discharge port, the material in water and mixing machine cylinder that a mixed technique filler pipe, dedusting water pipe spray turns
It is dynamic that the flue gas stream is captured, is settled, so that mixing machine cylinder be made to become " spray column " formula dust-extraction unit, make high concentrate dust
Flue gas becomes low concentration dust flue gas, to just be not easy to be bonded, block pipeline when causing air flow through cleaning shaft, guarantees dust removing tube
Road is unimpeded, makes chimney exhaust emissions meet the requirement of environmental protection；
2, flue gas carries out two-stage dust removal, after deduster two-stage dust removal, dust by entering deduster after cleaning shaft
Concentration further decreases, to reach emission request；
3, feed inlet seal closure and discharge port seal closure is respectively set in the inlet port and outlet port of mixing machine cylinder, and sets
The belt composition collecting hood being connected in feed inlet seal closure is set, dust is further prevented to leak.
Detailed description of the invention
Fig. 1 is the utility model mixing machine high-efficiency dust removal system structure schematic diagram.
Each part numbers are as follows in figure: mixture conveyor belt 1, belt dust collection cover 2, feed inlet seal closure 3, mixing
Machine cylinder 4, a mixed technique filler pipe 5, dedusting water pipe 6, discharge port seal closure 7, cleaning shaft 8, deduster 9, cesspool 10, wind

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
It is as shown in Figure 1 mixing machine high-efficiency dust removal system, including mixing machine cylinder 4 and 4 feed inlet face face of mixing machine cylinder
The feed inlet seal closure 3 of sealing, discharge port seal closure 7 and feed inlet seal closure with the sealing of 4 discharge port face face of mixing machine cylinder
Belt dust collection cover 2, the discharge end of 3 faces face sealing sequentially pass through belt dust collection cover 2 and feed inlet seal closure 3 until with
The connected mixture conveyor belt 1 of 4 feed inlet of mixing machine cylinder, setting 7 upper end of discharge port seal closure and 12 lower end of chimney it
Between negative pressure device, the cesspool 10, a mixed technique filler pipe 5 and the dedusting water pipe 6 that are connected with negative pressure device, and be respectively set
One end of multiple spray heads 14 on a mixed technique filler pipe 5 and dedusting water pipe 6, a mixed technique filler pipe 5 and dedusting water pipe 6 is equal
Across discharge port seal closure 7 until protruding into inside mixing machine cylinder 4, the other end of a mixed technique filler pipe 5 and external mixing
Technique water pipe is connected, and the other end of dedusting water pipe 6 is connected with cesspool 10；Wherein, negative pressure device includes passing through dust removing tube
The deduster 9 that road 8 is connected with 7 upper end of discharge port seal closure and the blower 11 being connected by pipeline with deduster 9, blower 11
It is connected with the bottom of chimney 12, deduster 9 is connected by sewage conduct 13 with cesspool 10.
When work, mixture is continuously transported to mixing machine with V1 speed in mixture conveyor belt 1 by sinter mixture
In cylinder 4, mixing machine cylinder 4 is rotated with the angular speed of V2, and the sinter mixture in mixing machine cylinder 4 is mixed well,
Certain water Q1 is sprayed at mixing machine cylinder 4 and mixed by the mixed technique filler pipe 5 in mixing machine cylinder 4 and its spray head 14 simultaneously
It closes on material, is sufficiently humidified so as to mixture；Blower 11 and deduster 9 and mixing machine cylinder 4 carry out electric interlock control, synchronize and open
It is dynamic, form certain negative pressure in 4 discharge port of mixing machine cylinder in this way, cause inside mixing machine cylinder 4, feed inlet, mixture it is defeated
Send dust on belt 1 to 4 discharge port of mixing machine cylinder with speed V3 flowing, formed one from 4 feed inlet of mixing machine cylinder to
The flue gas stream of discharge port, dedusting water pipe 6 and its spray head 14 inside mixing machine cylinder 4 spray one burst of dedusting water mist (water
Q2), to the flue gas " interception ", dust is captured, is settled, so that mixing machine cylinder 4 be made to become " spray column " formula dedusting dress
It sets, 4 middle and high concentration dust of mixing machine cylinder is subjected to spraying and dedusting, flue gas is made to become low concentration dust flue gas, from mixing machine circle
The cleaning shaft 8 of 7 upper end of discharge port dust collection cover of cylinder 4 is discharged, and reaches primary dedusting purpose.Control system intelligent control Q1 and
Q2, making Q1+Q2=Q, Q is that sinter mixture hybrid technique adds water inventory in mixing machine, both can fully ensure that mixing machine circle in this way
Dust removal by spraying water in cylinder, and can guarantee mixture hybrid technique amount of water demand.
The exhaust gas dust levels extracted out from mixing machine cylinder 4 are lower, in this way the air-flow pass through cleaning shaft 8 when just
It is not easy to be bonded, block pipeline, guarantees that cleaning shaft 8 is unimpeded.The flue gas enters 9 (two-stage dust removal of deduster after passing through cleaning shaft 8
Equipment is selected according to final emission request) two-stage dust removal is carried out, after 9 two-stage dust removal of deduster, dust concentration is further
It reduces, to reach emission request, it may also be necessary to which three-level special dust-removing equipment (two dedusters 9 of connecting, installation are set
It is convenient, simple), then it is discharged from chimney.The dedusting sewage discharged in two-stage dust removal is returned in cesspool by sewage conduct,
It is recycled and adds water and water for dust removal as mixing machine hybrid technique, without any sewage and sludge outlet, really realize zero
Discharge.
