1, principle: dust arrester is divided into three grades and sees accompanying drawing 1

The first order: adopt disc type filter 1 that big impurity and fiber in the dirty gas of blowing or comb and parallel cotton fibers prior to spinning, cotton ginning and noil or dusting fan discharge are adsorbed onto on the disk, see through disk than clean air and enter the second level, and the big trifle in the world and the fiber that are adsorbed on the disk pass through rotatable slit-aperture type suction nozzle on the disk hollow shaft, send on the dust cage surface of the cotton gatherer 22 of cyclone dust that is contained in outside the casing 7, on the fixed support, cotton dirt is separated, and the gas that sees through the dust cage mesh enters high pressure positive blower 25 air inlets that are contained on the antinose-dive leg by pipeline.Send 25 gases that go out the closed circuit two-stage dust removal device of sending into by high pressure positive blower, the cotton dirt that is separated is prepared reprocessing and is used.

The second level: adopt on the rotation dust cage 4 of four the efficient nonwoven filter of outsourcing dirt cloth, cleaned air after the filtration enters dust cage 4 inside and enters third level dust arrester, and be adsorbed on dust in the nonwoven by reciprocating type suction nozzle 9 sucking-offs that are contained in the casing 7 on the reciprocal suction nozzle trolley frames 35, by being contained in the high pressure positive blower 21 on the box body 3, send into dust compactor 20, be pressed into block output, do not have secondary pollution.

The third level: be a spraying box, airborne micronic dust is eliminated when air process spray water mist, and the clean air after the filtration is discharged to dirt pocket or workshop, has effectively utilized return air.The water of spray nozzle 12 ejections enters at the bottom of the case in the spraying box 14, and the clear water after filtering through filter screen 16 is sent into water spout again by the water pump 15 of casing outer bottom dress, recycles, and the micronic dust that is eliminated is regularly removed at the bottom of water tank.Secondary is an independent case body, and three grades of spraying box are connected by the screw on the skeleton with the I and II casing.Its basic structure is seen accompanying drawing 1, forms one-level by casing 7, disk filter 1, slit-aperture type suction nozzle 3, air inlet front shroud 2 and high pressure positive blower 25 and the cotton gatherer 22 of cyclone dust and filters.By casing 7, four rotating cages 4.And reciprocating type suction nozzle 9, high pressure positive blower 21, dust compactor 20 formed the cascade filtration devices.Form three grades of wet dedusting systems by spray casing 14, spray nozzle 12, water pump 15, screen pack 16, water tank 18, water fender 13.

Fig. 1, Fig. 3 are seen in basic transmission

The secondary gearing is finished by a transmission unit, through chain 26 transmission central shaft sprocket wheels 23 central shaft 27 is rotated by the sprocket wheel 13 that is contained on the electronic head by slowspeed machine 19, the bar seam suction nozzle 13 that is contained in when central shaft 27 rotates on the central shaft 27 rotates together, rotates simultaneously and the gear 11 of transmission cage spindle nose rotates dust cage 4 at the gear wheel 24 of central shaft 27 other ends.

Back and forth suction nozzle transmission: see that suction nozzle body transmission principle Fig. 5, Fig. 6 support revolution sprocket wheel 34 on 31 by the sprocket wheel of adorning on low speed stepless speed-regulating motor 29 deliveries 28 by the reciprocal suction nozzle of chain 30 transmissions separately, the revolution sprocket wheel 32 that suction nozzle supports on 31 is made up of 32 2 on biserial sprocket wheel, when circumversion chain 33 rotates, be contained in the reciprocal suction nozzle trolley frame 35 of chain and drag under chain drive, the suction nozzle that is contained on the suction nozzle trolley frame 35 is simultaneously reciprocating.Finish the clear suction on four dust cage surfaces.

Automatic control part: see Fig. 1, Fig. 7

Be equipped with in the case air pressure wind speed probe 8 and temperature smog probe 6 by line will visit side to data deliver to display and the adjustment knob that various data are housed on the computer control panel 36 that is contained in casing 7 outside on control panel, to regulate and control ruuning situation in overall process and the observation machine.

Principle of automatic control: the speed of low speed electromagnetic adjustable speed motor, reach the variation of bar seam suction nozzle rotating cage and reciprocating type suction nozzle speed by detecting head input computer and adjustment speed reducer speed by the variation of internal pressure, keep constant pressure in the case, when pressure surpasses the reservation value, divisor according to the show outside, the also shutdown of reporting to the police of computer notice electric bell.

If produce the condition of a fire in the system Anywhere, smog enters in the case, and computer is except that reporting to the police, with advancing to open extinguishing device (dress fire extinguisher or fountain head in the case).
