CN2179390Y - Cyclone compound fixed net duster - Google Patents

Abstract

The utility model discloses a dusting device for ginning industry, belonging to an inner set type double-layer fixed net duster. The utility model concentrates sucron, a bag and a pre-separator. Dusty air from the feeding blower of a processing workshop can enter into a cyclone head which is in a defined angle, airflow can be forced to do downward spiral movements at high speed, so that fuzzy fibres and foreign matters can be filtered for twice due to a centrifugal effect, and accordingly, the purpose of recovering fluff, collecting foreign matters, and purifying air can be obtained. The utility model has the advantages of stable working performance, high dust removing effect, no moving member, no power consumption, convenient maintenance and operation, and has the functions of self-cleaning for staple fibres and automatic recovery.

Description

Cyclone compound fixed net duster

The utility model relates to a kind of dust arrester, is used for collection cotton, collection suede, the exhausting-dusting of cotton ginning mill.

At present, the collection cotton, collection suede, the air draft impurity removing equipment that are used for the cotton ginning industry, usually adopt cyclone dust collectors cloth bag two-stage dust removal, because it is unreasonable that dust pelletizing system reclaims the suede network, cause and fly suede in a large number and leak, not only workshop condition is seriously polluted, and a large amount of effective fibers is blown off in vain, a spot of recovery suede is because of impure too much, and can't utilize, must be furnished with rod picker and various transfer equipment again, only the motor consumption of recovery system just surpasses 30 kilowatts, and whole construction investment spends nearly 460,000 yuans.

The purpose of this utility model is to overcome above shortcoming, and a kind of stable work in work simple in structure is provided, and equipment does not need to join power in addition, has self-cleaning, receives the short flannel function certainly, the efficiency of dust collection height, and the former saves that 400,000 yuan cyclone type is compound decides the net deduster output investment ratio.

Scheme of the present utility model is to be used to receive from the blast pipe of the place ahead dust laden air and to make spiral-shaped, the cyclone head that has spiral angle connects, be installed in the upper end of outer cylinder, the outer cylinder circumference is fastened with the one-level filter cloth, and the outer cylinder lower end is equipped with impurity collector.Center drum is installed in the center of outer cylinder, and outer rack is being fixed with flange and spider in the outside of outer cylinder, and outer rack circumference is fastened with the secondary filter cloth, and fluff collector is equipped with in the lower end.

The utility model compared with prior art has following advantage:

1, simple in structure, there is not movement parts, do not need to join in addition power, energy savings.

2, small investment, equipment only are the sixths of original equipment.

3, raw material reclaims high efficiency, the original equipment short flannel rate of recovery only 45%, and the utility model rate of recovery can reach 98%.

4, reduce filtrate consumption, former dust pelletizing system is made final dusting because of the need cloth bag, and annual the need changed, adopt the utility model only this item can save 24802.4 yuan every year, in sum, the cotton ginning mill of four types uses that a cover cyclone type is compound decide the net deduster, and production joint degree can be saved and the extra earning fund reaches 66.3 ten thousand yuan.

Be further described below in conjunction with accompanying drawing:

Accompanying drawing is the cutaway view of deduster.

Shown in figure: connect from the blast pipe 1 of the place ahead workshop dust laden air with make spiral-shaped cyclone head 3 and be connected; Be installed in the upper end of outer cylinder 4, the cyclone head spiral angle should be grasped and make inlet velocity 12-15m/s, filtration velocity 0.7-0.8m/s.Outer cylinder is fastened circumference with one-level filter cloth 6, and impurity collector 10 is equipped with in the lower end; Be shaped on impurity cleaning window 11 in the impurity collector bottom, center drum 2 is installed in the center of outer cylinder 4, the upper end closed of center drum, and run through cyclone head, diameter is to determine according to inlet velocity, air-flow fluid layer and air-flow dust content.Outer rack 8 passes through upper flange 13, middle cranse 5, and lower flange 12 and outer cylinder 4, center drum 2 is connected and fixed, and outer rack circumference is fastened with secondary filter cloth 7, and fluff collector 9 is installed in the lower end.Fluff collector, impurity collector are funnel shaped, and following bucket inclination angle is respectively greater than short flannel and impurity angle of repose.The two-stage filter cloth is fixed on cylinder and the rack, no relative motion, and one-level filter cloth specification is 60 order/inches, the secondary filter cloth is 120-140 order/inch.

That the utility model can be made as required is vertical, horizontal, inclined is so that install.

Its operation principle is the cyclone head that enters definite angle from the dust laden air of the defeated material blower fan of the place ahead job shop through certain speed, spiral-shaped and connect under the effect of the air-flow that goes in cyclone head, force air-flow to make downward high-speed screw (center drum plays guiding and steady air flow) formation one stable rotation air-flow that moves along outer cylinder and center drum gap, because outer cylinder has certain length, air-flow is in the backspin process, under centrifugal action, make thick foreign material of part and the outside cylinder inner wall of short velvet fiber move, and with descending rotational gas flow to enter one-level filter screen district, thick foreign material and staple fibre are under centrifugal action, thrown to filtering surface, and be blocked on the filter cloth inwall, because rotational gas flow effect and self proportion difference are assorted by collection at the bottom of brush is fallen machine respectively along filter cloth down, in the fluff collector, thicker impurity and fiber are separated with tiny micronic dust, reach and remove the thick assorted suede purpose of receiving.

Constantly spill into filter dirt district, the second level along filter screen from top to down through the tiny dust air after the one-level filtration, make the following rotational gas flow in one-level filter screen district decay gradually, this is that next part suede is created good condition, has also alleviated second level load of dust remove simultaneously.The air-flow of rotation is for the helical movement in filter dirt district at a high speed, has stoped the assorted dirt of fiber to be knotted on filtering net surface, makes air-flow in the whirlwind process self purification be arranged.Guaranteed that the filter screen inside and outside differential pressure is uniform and stable, also guaranteed the comparatively constant flow of primary air accordingly.In second level dedusting area, because the internal layer stream pressure is higher than skin, force air-flow to move to second level filter screen wire side, under the filtration of filtrate, micronic dust in the dust laden air is pounced on to be obtained, and outside the air discharge machine that purified, brush is to the short flannel of bottom, impurity utilizes the lingering remnants of past customs to enter collection suede impurity collector respectively, thus the purpose that reaches branch suede, dedusting, purifies air.
