Abstract
The utility model relates to a vertical negative pressure dust filter, which is composed of a primary filter, a secondary filter and an extruding separator with negative pressure fibres. The utility model is characterized in that the vertical negative pressure dust filter has a lower dust exhausting mechanism on which a tapered hopper, a funnel flange, an internal sleeve, a pressure shaft bearing, a driving gear wheel driven by a master gear wheel, and a driven gear wheel are arranged, and the lower dust exhausting mechanism is arranged on a chassis. The utility model has the advantages that because the form of the motion of a pressure shaft bearing is adopted as the form of the swivel motion of a secondary dust suction mechanism with filter cloths, so the actions are nimble, and the service life is long; because the seal of the dust collecting chamber of a secondary dust filtering and negative pressure dust exhausting mechanism adopts the form of the clearance fit of rabbets, so the sealing performance is good, the negative pressure is large, the suction force is strong, and the dust collecting effect is favorable.
Description
The utility model is a kind of dirt catcher, and particularly a kind of textile mills are that environment purification reclaims a kind of secondary negative pressure dirt catcher that the waste cotton short fiber uses.
Present EFU type dirt catcher, transmission mechanism is unreasonable, and rotation precision is poor, poor sealing performance, suction is little, and pick-up performance is poor, very easily causes the secondary pollution of secondary filter dirt.
Task of the present utility model is to design a kind of vertical secondary negative pressure dirt catcher, and this dirt catcher collection gives separator, and secondary filter, negative pressure Celloco fractionator Celloco be in one, compact conformation, and floor space is little, and the efficiency of dust filtration height is in order to overcome existing deficiency with dirt catcher.
Task of the present utility model can realize by following proposal:
The utility model promptly gives separator, secondary filter and negative pressure fiber extruding separator by grade one filter to be formed, and grade one filter and secondary filter are vertical, and secondary filter is sleeved on the outside of grade one filter, and two filters are sleeved on together.Grade one filter is made up of spirality public attention and nylon bolting silk, and secondary filter is chewed dust collection mechanism by fixed cylinder filter cloth and inner totally-enclosed negative pressure double suction thereof and formed the powerful nonwoven of effect during filter cloth is used.Negative pressure fiber extruding separator is arranged in the bottom of complete machine, the form of seam matched in clearance is adopted in the sealing of the aspiration chamber of secondary filter negative pressure dust discharge mechanism, the gyration of secondary filter cloth dust collection mechanism adopts the pressure bearing forms of motion, thereby realized the compound action of separation, filtration, control of dust.
The utility model has the advantages that:, thereby be active in one's movements long service life 1, because the pressure bearing forms of motion is adopted in the gyration of secondary filter cloth dust collection mechanism.2, because the form of seam matched in clearance is adopted in the sealing of the aspiration chamber of secondary filter dirt negative pressure dust discharge mechanism, thus good airproof performance, negative pressure is big, and suction force is strong, and pick-up performance is good.
Below in conjunction with accompanying drawing the utility model is done detailed description further.
Fig. 1 is an overall structure cross-sectional schematic of the present utility model
Fig. 2 is following dust discharge mechanism cross-sectional schematic
As Fig. 1--shown in 2, spirality public attention (1) front is seen as rectangle among the figure, overlooks and sees as the hair-dryer shape, and spirality public attention (1) is positioned on public attention flap (9).Public attention flap (9) is the circle female cap, along outer and interior edge screw hole is arranged, and keeps supplying column (2) and spirality public attention (1).There is the mechanism of peace one-level filter cloth (11) and secondary filter cloth (12) public attention flap (9) bottom surface.One-level filter cloth (11) and secondary filter cloth (12) are the members of one-level dirt catcher and secondary dirt catcher.One-level filter cloth (11) is termination conical hopper (7) down, and secondary filter cloth (12) is termination chassis (4) down.Column (2) is a long bolt, and column (2) has the six roots of sensation, and column (2) lower end also is connected with chassis (4).Suction is chewed (10) and is tubular, and there is elbow the lower end, and (10) are chewed in suction two, and suction is chewed (10) and is installed in down in the dust discharge mechanism (3).Following dust discharge mechanism (3) is by conical hopper (7), funnel flange (15), interior cover (14), pressure bearing (13), driving gear and driven gear that driving gear shaft (8) drives, and driven gear is installed on the outer ring of swivel becket (16).Be covered with annular sheet lid (17) on the driving gear.Following dust discharge mechanism (3) is installed on the chassis (4).Pacify support (5) and fiber extruding separator (6) on the bottom surface, chassis (4), fiber extruding separator (6) is by cylinder, extruding transfer roller, following funnel and motor are formed, motor is installed on the support (5), motor shaft head is connected with the extruding transfer roller, drive the extruding transfer roller and rotate, reach separating of long fibre and flying dust.
The course of work of the present utility model is: under the effect of blower fan, contain the inlet of the air of fiber and flying dust by spirality public attention (1), with speed limit rotation tangentially greater than 15mm/S, being introduced into grade one filter is in the one-level filter cloth (11), under pressure and action of centrifugal force, airborne tiny flying dust sees through one-level filter cloth (11) and enters two progressive filter clothes (12), it is online to be attached to cascade filtration, online fine dusts is chewed under the swabbing action of (10) at secondary filter dirt negative pressure double suction, chew (10) through suction and enter the control of dust bellows, be collected in the dirt bag.And thick dust and short fiber separate in separator (6), and fiber is output and recycles under the effect of its propelling simultaneously.
The utility model is iron and steelwork except that one-level filter cloth (11), secondary filter cloth (12).
Claims (4)
1, a kind of vertical negative pressure dirt catcher, promptly giving separator, secondary filter and negative pressure fiber extruding separator by grade one filter forms, grade one filter and secondary filter are vertical, secondary filter is sleeved on the outside of grade one filter, two filters are sleeved on together, it is characterized in that having on the grade one filter spirality public attention (1) and one-level filter cloth (11), have fixed cylinder filter cloth (12) and inner totally-enclosed negative pressure double suction to chew (10) dust collection mechanism on the secondary filter, filter cloth is the powerful nonwoven of middle effect; Negative pressure fiber extruding separator (6) is arranged in the bottom of complete machine; The form of seam matched in clearance is adopted in the sealing of the aspiration chamber of dust discharge mechanism (3) under the secondary filter dirt negative pressure; The forms of motion of pressure bearing (13) is adopted in the gyration of secondary filter cloth dust collection mechanism.
