Description
Technical field
The utility model belongs to the environmental protection equipment field, relates in particular to a kind of electrostatic precipitation system of mobile dumper.
Background technology
Loose shape material system storage bin Cang Ding generally adopts moving unloading vehicle, because dummy car is limit by unfixed point discharging and factory building condition, only does the dedusting of storagetank in general design.To the dedusting of dummy car, because of domestic, do not have mature experience can supply to use for reference, therefore generally do not consider dedusting.Because material is dry, drop is large, dust-producing amount is many, and the dummy car top has a large amount of dusty gases to escape, and has seriously polluted the environment of production station, causes hilllock tears dust concentration to exceed standard.Therefore, solving the movable belt conveyor dummy car dedusting of top, storage bin storehouse is a pressing problem.
Summary of the invention
But the utility model is intended to overcome the deficiencies in the prior art part and provides a kind of Multipoint weighting, dust removing effects ideal, the electrostatic precipitation system of mobile dumper that can carry out automation control.
For solving the problems of the technologies described above, the utility model is achieved in that the dummy car dust collecting system, and it comprises mobile dummy car, head dust shield, charging conduit, feed bin seal bootr and material conveying mechanism; Described material conveying mechanism is assigned on mobile dummy car; Described head dust shield and charging conduit are fixedly connected; The discharge end of described charging conduit communicates with the feed bin feeding end; Be provided with dust airflow reflux passage between described feed bin seal bootr and charging conduit; The port of described dust airflow reflux passage communicates with feed bin and charging conduit respectively; Is furnished with electrostatic dust-removal terminal in described feed bin seal bootr; The signal output part of described power unit connects the signal input part of electrostatic dust-removal terminal.
As a kind of preferred version, electrostatic dust-removal terminal described in the utility model comprises corona wire and the insulator be fixedly connected with it.
The utility model can be realized the automation mechanized operation of equipment to the dedusting of field conduct Multipoint weighting, the dust atmosphere of the utility model in discharge process is polluted and be effectively controlled.Because the utility model adopts the dust airflow reflux channel pattern between feed bin seal bootr and charging conduit, utilize the pressure equilibrium principle, automatically adjust the pressure in feed bin, system energy consumption is low, the dust removing effects ideal.In addition, the utility model sets up electrostatic dust-removal terminal and can further suppress the excessive of dirt source above the dirt source.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Fig. 1 is integral structure schematic diagram of the present utility model.
In figure: 1, mobile dummy car; 2, head dust shield; 3, charging conduit; 4, material conveying mechanism; 5, feed bin seal bootr; 6, dust airflow reflux passage; 7, corona wire; 8, insulator.
The specific embodiment
As shown in the figure, the dummy car dust collecting system, it comprises mobile dummy car 1, head dust shield 2, charging conduit 3, feed bin seal bootr 5 and material conveying mechanism 4; Described material conveying mechanism 4 is assigned on mobile dummy car 1; Described head dust shield 2 is fixedly connected with charging conduit 3; The discharge end of described charging conduit 3 communicates with the feed bin feeding end; Be provided with dust airflow reflux passage 6 between described feed bin seal bootr 5 and charging conduit 3; The port of described dust airflow reflux passage 6 communicates with feed bin and charging conduit 3 respectively; Is furnished with electrostatic dust-removal terminal in described feed bin seal bootr 5; The signal output part of described power unit connects the signal input part of electrostatic dust-removal terminal; Described electrostatic dust-removal terminal comprises corona wire 7 and the insulator 8 be fixedly connected with it.
The bottom of storehouse described in the utility model seal bootr 5 can adopt portable structure.
The utility model mobile dummy car, when discharging, first moves to system feed bin Hatch Opening top, and material is delivered to mobile dummy car head position by material conveying mechanism 4 by it, and under effect of inertia, material falls along charging conduit 3.Material from material conveying mechanism 4 falling point upstreams has produced a large amount of dust in dropping process, simultaneously, the shock pressure fallen based on material, make charging conduit 3 regional areas form negative pressure, the dust air-flow is at feed bin seal bootr 5, dust airflow reflux passage 6 and 3 sections formation circulation of charging conduit, can effectively slow down the shock pressure that material produces in charging conduit 3 like this, dust-laying effect is obvious.For increasing dust removing effects, the utility model can arrange dust collector in mobile dummy car head position.
The dust air-flow, in motion process, owing on the interior electrostatic dust-removal terminal of feed bin seal bootr 5, applying the electrostatic field that the superhigh pressure generation of static electricity is powerful, makes dust moment charged, and the dust purified after catching is turned back to material.
The ratio resistance of dust is the index of estimating electric conductivity, and it has direct impact to efficiency of dust collection.More too low than resistance, grit is difficult to remain on collecting electrode, causes it to return to air-flow.Than too high in resistance, the grit electric charge that arrives collecting electrode is difficult for emitting, and forms voltage gradient and can produce partial breakdown and electric discharge phenomena between knoisphere.These situations all can cause efficiency of dust collection to descend.The power supply of electrostatic precipitator is comprised of control box, step-up transformer and rectifier.The voltage height of power supply output also has a significant impact efficiency of dust collection.Therefore, the electrostatic precipitator running voltage need keep 40～75kV and even more than 100kV.
Be understandably, above about specific descriptions of the present utility model, only for being described, the utility model not is limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
