Abstract
The utility model discloses a kind of deduster fold shape filter bag, comprise the bag body being connected to cylindrical opening portion, be located at the support frame that bag body is interior, its upper end is connected to cylindrical opening subordinate periphery, described bag body is provided with longitudinal fold, and bag body peripheral cover has retainer plate.When deduster work, when shared by equipment when constancy of volume, the contact area of dusty gas and filter bag becomes greatly, and dust removing effects strengthens.During deashing, filter bag sharply expands instantaneously, and retainer plate effectively can play cushioning effect, and guarantee filter bag can not damage because moment sharply expands, and it also avoid because moment sharply expands, filter bag contacts, rub and affect ash-removal effect, produces friction and causes damage.The utility model is under the prerequisite of shared space invariance, and filter bag and dusty gas contact area increase, good dedusting effect, effectively reduces filter bag ash removal number of times, extends life of bag filter, reduces costs, increase work efficiency.
Description
Technical field
The utility model relates to a kind of dust processing equipment, is specifically related to a kind of fold shape filter bag of pulsed sack cleaner.
Background technology
Sack cleaner is a kind of dry-type dedusting equipment, is applicable to trap tiny, dry non-fiber dust granules.When dusty gas enters deduster by air inlet, first encounter the swash plate in the middle of inlet and outlet and baffle plate, air-flow just diverted flow enters ash bucket, and air velocity slows down simultaneously, due to effect of inertia, makes crude particle dust in gas flow directly into ash bucket.Play the effect of gathering dust in advance, the air-flow entering ash bucket is rolled over subsequently and the filter bag of metallic framework is upwards housed by inside, dust is trapped in the outer surface of filter bag, purified gas enters top, filter bag room clean room, be pooled to air outlet to discharge, in the process that dusty gas is purified by filter bag, along with the increase of time, the long-pending dust be attached on filter bag gets more and more, thus increase resistance of the filter bag, process air quantity is caused to reduce gradually, for normal work, control resistance within the specific limits, deashing must be carried out to filter bag, by each control valve of pulse control instrument sequence trigger switch and unbalanced pulse valve during deashing, compressed air in gas tank is by injection tube, each aperture Venturi tube is ejected in each corresponding filter bag, filter bag moment sharply expands, make the long-pending dust releasing being attached to filter bag surface, filter bag is regenerated.Clear lower dust falls into ash bucket, discharges body through dust removing system.Make the long-pending dust pulse jetting deashing be periodically attached on filter bag thus, make Purge gas normal through, ensure that duster system runs.
For a cleaner, the service life of filter bag is most important, and be the key factor in the service life affecting filter bag on the number of times that filter bag carries out deashing, existing filter bag of dust collector is the cylindric filter bag of surface smoothing, there is integral filter area less than normal, cause that deduster operating air velocity is too high, resistance is comparatively large, deashing number of times carries out to filter bag frequent, comparatively large to the erosive wear of cloth bag, cause that cloth bag breakage rate is higher, house outlet soot emissions exceed standard.
Utility model content
The purpose of this utility model is the deficiency solving existing equipment, provides a kind of fold shape filter bag of deduster.
The utility model is achieved through the following technical solutions:
A kind of deduster fold shape filter bag, comprise the bag body being connected to cylindrical opening portion, be located at the support frame that bag body is interior, its upper end is connected to cylindrical opening subordinate periphery, described bag body is provided with longitudinal fold, and bag body peripheral cover has retainer plate.
The further improvement project of the utility model is:
Described longitudinal fold extends to a bag body lower end continuously from bag body upper end.
Described longitudinal fold decile is arranged on bag body, and described bag body cross-section is petal.
Described support frame is the bar that upper end is connected to cylindrical opening subordinate periphery, and described bar is provided with two side by side, and the pleat that described bar is positioned at each longitudinal fold falls into portion.
Described retainer plate is bonded in or is fixed on the pleat protuberance of fold by the mode sewed up.
Described retainer plate is provided with multiple, is uniformly distributed in from top to bottom on bag body.
Described retainer plate and bag body are same material.
The beneficial effects of the utility model are:
Under the prerequisite of shared space invariance, filter bag and dusty gas contact area increase, good dedusting effect, effectively reduce filter bag ash removal number of times, extend life of bag filter, reduce costs, increase work efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the sectional view at the utility model A place:
In figure, 1-opening portion, 2-bag body, 3-support frame, the longitudinal fold of 4-, 5-retainer plate.
Detailed description of the invention
As shown in Figure 1, the utility model comprises the bag body 2 being connected to cylindrical opening portion 1, be located at the support frame 3 that bag body 2 is interior, its upper end is connected to following peripheral, cylindrical opening portion 1, it is characterized in that: described bag body 2 is provided with longitudinal fold 4, bag body 2 periphery cover has retainer plate 5.Longitudinal fold 4 extends to bag body 2 lower end continuously from bag body 2 upper end, and decile is arranged on bag body 2, and bag body 2 cross section is petal.Support frame 3 is connected to the bar of following peripheral, cylindrical opening portion 1 for upper end, and bar is provided with two side by side, and the pleat that bar is positioned at each longitudinal fold 4 falls into portion.Retainer plate 5 is bonded in or is fixed on the pleat protuberance of fold 4 by the mode sewed up, and retainer plate 5 is provided with multiple, is uniformly distributed on bag body 2 from top to bottom, and retainer plate 5 and bag body 2 are same material.
When deduster work, when shared by equipment when constancy of volume, the contact area of dusty gas and filter bag becomes greatly, and dust removing effects strengthens.During deashing, filter bag sharply expands instantaneously, and retainer plate 5 effectively can play cushioning effect, and guarantee filter bag can not damage because moment sharply expands, and it also avoid because moment sharply expands, filter bag contacts, rub and affect ash-removal effect, produces friction and causes damage.
