Said dust collection cover is taper type.
Adopt the beneficial effect of technique scheme: the mode of these asphalt mixing plant flash dust collection treating apparatus employing ventilation and dust removal and water curtain formula dedusting method carry out dedusting and processing to the dust in flash pipe exit, and dust is transported to by force and mixes in the dust pelletizing system.The outlet of the material receiving tube in the dust collection cover is provided with flap valve, and flap valve is by its folding of lever controlling organization control.When no flash, externally under the effect of counterweight, valve plate seals the flash discharging opening to flap valve; When flash reached a certain amount of, under the gravity effect of flash (moment is above the moment that produces in joining), flap valve was opened around the shaft; Flash begins to efflux, and this moment, cursor touched mechanical limit switch, and signal is transferred into pump motor and the id-motor in the water curtain formula dust arrester; Air-introduced machine begins exhausting, and water has formed a circle water curtain downwards under the effect of high-pressure hydraulic pump, thereby has stoped overflowing of dust; Under the effect of axial flow blower, dust gets in the dust pelletizing system through the air inducing pipeline, thereby has solved flying upward of dust.The two-layer stratigraphic structure that said dust collection cover is made up of outer wall and inwall; Between inside and outside wall, form the dust suction cavity, the inwall of dust collection cover is provided with the air vent of strip, according to aerodynamic principle; To dust suction cavity exhausting; Form more powerful suction in vent, the dust in the dust collection cover inner chamber is extracted out by outer speed, and pick-up performance is good.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of utility model.
The specific embodiment
As shown in Figure 1, this asphalt mixing plant flash dust collection treating apparatus has a dust collection cover, and said dust collection cover is taper type, and is also cylindrical.The two-layer stratigraphic structure that said dust collection cover is made up of outer wall 15 and inwall 11 forms dust suction cavity 12 between inside and outside wall.Said dust collection cover top is provided with the material receiving tube 1 that is connected with flash pipe discharging opening, and the outlet of material receiving tube is positioned at dust collection cover, and the outlet of said material receiving tube is provided with flap valve 2; Flap valve is by its folding of lever controlling organization control; Said lever controlling organization has the arm bar 5 that is fixedly connected with flap valve, and the medial extremity of arm bar is hinged in the rotating shaft 3, and rotating shaft 4 fixedly is located on the dust collection cover; The outboard end of arm bar is mounted with balancing weight 6, and the weight of balancing weight 6 is set according to actual conditions.The outer wall 15 of dust collection cover is provided with the aspiration channel 16 that is connected with dust suction cavity 12, is connected with axial flow blower 13 on the said aspiration channel 16, and the outlet of aspiration channel is connected with the pipeline of mixing dust pelletizing system by force through pipeline.The inwall 11 of said dust collection cover is provided with air vent 14, and said air vent is the strip that vertical direction is provided with, and the air vent of said strip is a plurality of, on the inwall that is arranged in dust collection cover.The bottom of said dust collection cover is provided with water curtain formula dust arrester; Said water curtain formula dust arrester has the sparge pipe 9 that is coiled in dust collection cover bottom one circle; Be evenly equipped with a plurality of directions shower nozzle 10 down on the sparge pipe 9; Sparge pipe connects high-pressure hydraulic pump 7 through pipeline 8, under dust collection cover, forms a circle water smoke curtain during sparge pipe 9 work, stops dust outwards to be revealed.Said high-pressure hydraulic pump 7 has the mechanical limit switch 4 of controlling its opening and closing with axial flow blower 13, and said mechanical limit switch 4 is arranged on flap valve and opens the position that the back arm bar can touch.
