Description

A kind of 64 bag dust collectors

Technical field

The utility model relates to leather processing equipment technical field, especially a kind of 64 bag dust collectors.

Background technique

It in the production process of leather, needs to carry out grinding processing to leather, to improve the presentation quality of leather.Buffing packet Include the grinding to the grain layer and tapetum (close to one layer of muscle) of leather.Since buffing can generate a large amount of dust, these Dust may result in cancer, can generate serious actual bodily harm to the producer, therefore existing buffing machine is generally all set It is equipped with dust-extraction unit.The dust-extraction unit of existing buffing machine is generally the brush roll for having bristle, the brush rotated during buffing Roller by under the abrasive dust brush on leather, taken away by blower again by the abrasive dust under brushing.

The gas with abrasive dust that blower is taken away will be discharged after deduster is handled, in current leather machine industry Deduster mostly select: cyclone dust collectors, more dedusters, pulse back blow bag dust collector.Wherein, cyclone dust collectors: belong to Dustproof function is removed in the effect using centrifugal force, this old-fashioned deduster has been eliminated at present, current primarily as other The auxiliary primary dust removing of deduster is used, and efficiency of dust collection is lower, very unsatisfactory for fine particle dusts effect；More dedustings Device: belong to multistage filtering, sweep up dust and inhale the deduster of ash, structure is complicated, high failure rate, and power is big (close to 50 kilowatts in energy consumption Power), and stand-alone device installation takes up a large area (than 2 times more than 64 bag dust collectors)；Pulse back blow bag dust collector: bag Deduster is the cleaner that current environmental protection administration strongly promotes, and efficiency of dust collection is up to 99% or more, dust discharge amount close to 0, Dedusting is using negative-pressure adsorption dust to bag case, and filtered air is taken away through filter bag, and the dust being adsorbed on sack, which passes through, is The pulse valve release compressed air of system control carries out positive-pressure back blowing, after the compressed air instantaneous burst of big flow shock wave blow off, Vibration fall the dust adsorbed on filter bag, from the purpose of not up to off-line ash-clearing, this bag dust collector there are the problem of there are two: one, It is larger to the consumption of compressed air, waste energy consumption；Two, cost of manufacture is high, structure is complicated, wherein diaphragm valve control and blowback machine Structure also needs closed cabinet, and the maintenance cost of diaphragm valve is also higher.

Utility model content

For above situation, the purpose of the utility model is to provide a kind of 64 bag dust collectors, can high-effective dust-removing, energy consumption It is small, highly reliable, low manufacture cost.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

A kind of 64 bag dust collectors, including bracket, filter bag, equal gas chamber, ash hopper and filter bag ash handling equipment, the gas Room is fixed on bracket, and the upper end is air inlet, and lower end is connected with the import of filter bag, and the outlet of filter bag is through fixed plate and ash hopper Import be connected, fixed plate is connected by flexible piece with the inner sidewall of ash hopper, the filter bag ash handling equipment include setting Limit plate in the middle part of filter bag, limit plate are connected on bracket by spring, and to match with limit plate is equipped on bracket One shakes cylinder, and the second shake cylinder is provided on bracket, and the second shake cylinder matches with fixed plate.

64 bag dust collectors of the utility model as the term suggests be exactly comprising 64 filter bags, in prepared by leather, Dust particles under indoor buffing machine mill, are taken away, blower is placed on outside buffing room, such machine by the materiel fan of 22KW Noise does not interfere with indoor operator.The dusty gas that blower is taken away begins to change into positive pressure by fan outlet, through air inlet Pipeline is sent into deduster, uniformly to 64 filter bags in the equal gas chamber in the top of positive pressure dusty gas from 64 bag dust collectors Positive pressure is blown away, and dust is inside filter bag, and the gas of purification is precipitated outside filter bag, and dust adhesion is in efficient filter-bag.With negative pressure Unlike pulse bag type dust collector, the dust of 64 bag dust collector will not leak ash to outside, eliminate close in filter bag The high cost of manufacture of joint sealing body.The dust being adsorbed in filter bag is carried out vibration by the movement of shake cylinder and trembles ash, shaken off Dust is discharged by ash hopper.The pulse diaphragm valve that the ash disposal mode is different from negative pressure bag dedusting controls blowback big flow, high energy consumption Compressed air soot-blowing.

In the utility model, the air inlet of the equal gas chamber is connected with admission line, and the bottom of equal gas chamber offers outlet Hole, the venthole match connection with the import of filter bag.

According to the utility model, ash output opening is offered in the fixed plate, the ash output opening matches company with the outlet of filter bag It connects.

Preferably, the flexible piece is strainer, and strainer is loosely connected between fixed plate and ash hopper inner sidewall.It is flexible The setting of part mainly cooperates the shake of filter bag, enable the lower end of filter bag freely up and down, double swerve.

Preferably, through-hole is provided on limit plate, the through-hole matches with filter bag, and filter bag is limited by passing through in through-hole In on bracket, the first shake cylinder is horizontally fixed on bracket for plate horizontal connection, and the piston of the first shake cylinder is flexible can be made to limit Position plate shake.Limit plate on the one hand position-limiting action is played to filter bag, make it is relatively independent between each filter bag, on the other hand, can make Filter bag can be used as the side wall of the whole flexible collision limit plate for carrying out shake control, shaking cylinder by first, in conjunction with spring The shake of retractility realization filter bag.

Preferably, the second shake cylinder is fixed on bracket vertically, and support frame, the second shake are provided in fixed plate The piston of cylinder is flexible can to push support frame that filter bag is made to be tensioned or relax.Fixed plate can be such that the lower end of filter bag is fixed, simultaneously Support frame is pushed up and down with the second shake cylinder, moves up and down fixed plate, filter bag shakes ash disposal.

In the utility model, the first shake cylinder and the second shake cylinder can be acted on simultaneously or be acted on respectively, the One shake cylinder contains at least one cylinder, and the second shake cylinder includes at least symmetrically arranged two cylinders.

The utility model further includes the other components that can make the 64 bag dust collector normal use, belongs to this field Conventional selection.In addition, the device limited or component is not added to be all made of the conventional means in this field, example in the utility model Such as, the driving device and mode etc. of cylinder.

The action principle of 64 bag dust collectors of the utility model are as follows: the dusty gas sent by upstream fan is through gas Room, into each filter bag, filtered clean gas is overflowed by filter bag, and dust stays in filter bag, the first shake Telescopic-cylinder, punching Limit plate is hit, filter bag is made to shake ash disposal, the second shake Telescopic-cylinder drives fixed plate to move up and down, makes filter bag in the longitudinal direction It tightens or relaxes, carry out trembling ash, the first shake cylinder and the second shake cylinder can act on simultaneously, and dust is discharged by ash hopper, Into after-treatment device.

64 bag dust collectors of the utility model by reasonable structure setting, can high-effective dust-removing, solve buffing process The problem that Dust Capacity is big, stickiness is big, dedusting is difficult, energy saving (water, electricity), highly reliable, price is low.
