Described dust collection cover is taper type.
Adopt the beneficial effect of technique scheme: this asphalt mixing plant flash dust collection treating apparatus adopts the mode of ventilation and dust removal and water curtain curtain dedusting method to carry out dedusting and process to the dust in overflow pipe exit, and dust is transported to be mixed by force in dust pelletizing system.The outlet of the material receiving tube in dust collection cover is provided with flap valve, and flap valve controls its folding by lever controlling organization.When without flash, flap valve is under the effect of outside counterweight, flash discharging opening seals by valve plate, when flash reaches a certain amount of, under the Action of Gravity Field of flash (moment exceedes the moment of joining middle generation), flap valve is opened around the shaft, flash starts outer row, now cursor touches mechanical limit switch, signal is transferred into pump motor in water curtain curtain dust arrester and id-motor, air-introduced machine starts exhausting, water defines a circle water curtain downwards under the effect of high-pressure hydraulic pump, thus prevent the spilling of dust, under the effect of axial flow blower, dust enters in dust pelletizing system by air inducing pipeline, thus solve flying upward of dust.The two-layer stratigraphic structure that described dust collection cover is made up of outer wall and inwall, dust suction cavity is formed between inside and outside wall, the inwall of dust collection cover is provided with the gravity vent of strip, according to aerodynamic principle, to dust suction cavity exhausting, form more powerful suction at disposed at air vent, the dust in dust collection cover inner chamber is extracted out by outer speed, and pick-up performance is good.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of invention.
Detailed description of the invention
As shown in Figure 1, this asphalt mixing plant flash dust collection treating apparatus, have a dust collection cover, described dust collection cover is taper type, may also be cylindrical.The two-layer stratigraphic structure that described dust collection cover is made up of outer wall 15 and inwall 11, forms dust suction cavity 12 between inside and outside wall.Described dust collection cover top is provided with the material receiving tube 1 be connected with overflow pipe discharging opening, the outlet of material receiving tube is positioned at dust collection cover, the outlet of described material receiving tube is provided with flap valve 2, flap valve controls its folding by lever controlling organization, described lever controlling organization has the arm bar 5 be fixedly connected with flap valve, and the medial extremity of arm bar is hinged in rotating shaft 3, and rotating shaft 4 is fixedly located on dust collection cover, the outboard end of arm bar is mounted with balancing weight 6, and the weight of balancing weight 6 sets according to actual conditions.The outer wall 15 of dust collection cover is provided with the aspiration channel 16 be connected with dust suction cavity 12, and described aspiration channel 16 is connected with axial flow blower 13, and the outlet of aspiration channel is connected with the pipeline mixing by force dust pelletizing system by pipeline.The inwall 11 of described dust collection cover is provided with gravity vent 14, and described gravity vent is the strip that vertical direction is arranged, and the gravity vent of described strip is multiple, around being arranged on the inwall of dust collection cover.The bottom of described dust collection cover is provided with water curtain curtain dust arrester, described water curtain curtain dust arrester has the sparge pipe 9 being coiled in a circle bottom dust collection cover, sparge pipe 9 is evenly equipped with multiple directions shower nozzle 10 down, sparge pipe connects high-pressure hydraulic pump 7 by pipeline 8, under dust collection cover, form a circle water smoke curtain when sparge pipe 9 works, stop dust to outward leakage.Described high-pressure hydraulic pump 7 and axial flow blower 13 have the mechanical limit switch 4 controlling it and open and close, and described mechanical limit switch 4 is arranged on flap valve and opens the position that rear arm bar can touch.
