Description

A kind of flat bag-type dust collector

Technical field

The utility model relates to environmental protection cleaner technical field, relates in particular to a kind of flat bag-type dust collector.

Background technology

In chemical industry; Often need industrial chemicals such as breeze etc. be carried out roasting,, in roasting process, can produce the high-temperature smoke of forming by gas, vaporous water and dust etc. in the body of heater to make required product; If above-mentioned flue dust is directly discharging; Not only can pollute environment, and the dust major part in the above-mentioned flue dust all can recycle, directly discharging also causes a large amount of wastes of industrial chemicals.Mostly be to adopt sack cleaner to reclaim in the prior art; Its operation principle is dusty gas to be incorporated in the casing of sack cleaner through connecting pipeline; Dusty gas is moved to filter bag by the graviational interaction of air-introduced machine; Dust is attracted on the filter bag, and cleaned gas is then discharged in filter bag, thereby reaches the effect of air cleaning.

In the existing sack cleaner; Vibration body be shaped as rectangular frame component or its horizontal respectively I-shaped in both sides up and down; The drive installation frame can drive cloth bag bottom and vibration body moves together, the upper end of vibration body is produced rock and impact cloth bag and carry out dedusting, but the frame component of this vibration body is not to contact with whole filter bags; Be prone to cause the dust local shedding on the filter bag, the filter bag efficiency of dust collection is low; In addition, the right angle portion filter bag easy to wear of frame component has shortened service life of filter bag.

The utility model content

The problem that causes the low and heavy wear filter bag of efficiency of dust collection to the frame component in the existing sack cleaner vibration body; The purpose of the utility model provides a kind of simple structure, safe in utilization, and can improve the purification efficiency of sack cleaner and the flat bag-type dust collector of dust removing effects.

The utility model solves the technical scheme that its technical problem adopted: it comprises that two ends are respectively equipped with the casing of air inlet and air outlet; The inner chamber of said casing is divided into air-purifying chamber and filter bag chamber from top to bottom; The indoor filter of forming by a plurality of frameworks and the filter bag of gap arrangement on said framework that is provided with of said filter bag; Ash bucket is arranged at the bottom of said casing; The opening end of said ash bucket communicates with said filter bag chamber and said air inlet; It comprises that also one can impact the deashing mechanism of said filter bag, and said deashing mechanism comprises that at least one is horizontally disposed with and two ends are connected vibration thick stick and at least one vibrating motor on the said filter bag chamber interior walls, and said vibration thick stick links to each other with said vibrating motor through eccentric wheel.

It comprises that also one is arranged at the spraying and blowing organ at said air-purifying chamber top, and said spraying and blowing organ is connected with controller.

The effect of this patent is: the dust arrester of the utility model adopts the mode of vibration deliming, runs through vibration thick stick and each filter bag even contact that casing is provided with, makes each filter bag vibration evenly, has improved efficiency of dust collection; The wearing and tearing of the right angle portion of frame component in the prior art to filter bag have been avoided in the setting of horizontal vibration thick stick, have reduced the loss of filter bag; In addition, rational deashing program and cleaning cycle have guaranteed the ash-removal effect and the life-span of the filter bag of dust arrester.Therefore, the setting of deashing mechanism more helps removing the dust on filter bag surface in the utility model, has improved operating efficiency.

The specific embodiment

The flat bag-type dust collector of the utility model is described in conjunction with Fig. 1; It comprises that two ends are respectively equipped with the casing 100 of air inlet 103 and air outlet 104; The inner chamber of casing 100 is divided into air-purifying chamber 101 and filter bag chamber 102 from top to bottom; Be provided with the filter of forming by a plurality of frameworks and the filter bag of gap arrangement on framework in the filter bag chamber 102, the parallel distribution of framework and being hung vertically on the support of casing 100.The filtrate of filter bag is cloth or the felt that is made into by synthetic fibers, natural fiber or glass fibre.The ash bucket 107 of inversed taper platform shape is arranged at the bottom of casing 100, and its opening end all communicates with filter bag chamber 102 and air inlet 103, and the cinder-discharging port place, bottom of ash bucket 107 is provided with ash discharge motor 108.

It comprises that also one can impact the deashing mechanism of filter bag; Deashing mechanism comprises three side by side and be horizontally placed on vibration thick stick 105 and three vibrating motors 106 in the filter bag chamber 102; The two ends of vibration thick stick 105 are movably connected on the inwall of casing 100 through eccentric wheel respectively, and vibration thick stick 105 links to each other through the eccentric wheel vibrating motors 106 outer with being arranged at casing 100.

The spraying and blowing organ 109, vibrating motor 106, ash discharge motor 108 and the centrifugal blower 111 that are arranged at air-purifying chamber 101 tops all connect to form the automatic control system of bag-type dust collector with controller.

The course of work: the gas that under the acting in conjunction of pressure fan and centrifugal blower 111, contains dust rushes at ash bucket 107 by air inlet 103 at a high speed along gas channel; The dirt group of thick grit of a part and cohesion; Because effect of inertia directly falls into ash bucket 107, plays the effect of collecting dirt in advance.The air-flow of entering ash bucket 107 is turned back and is upwards poured in casing 100; When it passes through the filter bag of filter bag chamber 102; Dust is delayed at the outer surface of filter bag, and purified gas gets into the air-purifying chamber 101 on 102 tops, filter bag chamber and is pooled to air outlet 104, is discharged with induced duct 110 by centrifugal blower 111.Constantly carry out along with what filter, the laying dust of filter bag outer surface increases gradually, and the resistance of dust arrester also increases gradually.When the thickness of filter bag surface dust reached setting value, the control system sent the deashing instruction, closes centrifugal blower 111; Open vibrating motor 106; Drive 105 vibrations of vibration thick stick through eccentric wheel, the dust that is deposited on the filter bag surface is shaken come off and drop in the ash bucket 107, simultaneously; Compressed air carries out online ash removal through being installed in the spraying and blowing organ 109 at casing 100 tops to filter bag.Remove the dust of filter bag outer surface, then, open air bleeding valve and open ash discharge motor 108, dust is discharged through cinder-discharging port and is made filter bag chamber 102 recover to filter.

Those skilled in the art will recognize that; The above-mentioned specific embodiment is exemplary; Be in order to make those skilled in the art can better understand this patent content; Should not be construed as is the restriction to this patent protection domain, changes or modifies so long as disclose spiritual any being equal to of being done according to this patent, all falls into this patent protection domain.
