Abstract
The utility model relates to a filter bag fastening and sealing device for dust collectors. A conical sealing oblique fastening sleeve is welded and installed below a chipboard hole; the bag mouth of the filter bag is positioned behind the sealing oblique fastening sleeve and is tensioned on the inner wall of the oblique fastening sleeve by a self-locking tension spring to realize filter bag seal. The utility model has the advantages of convenient installation and maintenance, high dust removing effect, long service life and reduced volume of devices, and avoids the filter bag leaking ash.
Description
The utility model relates to the sealing of filter bag opening, and it belongs to the parts on the isolation technics operating equipment.
Current sack cleaner can be divided into two big classes, and a class is interior filter structure (is called for short in filter), it be a kind of dust stratification on the filter bag inwall, when dust stratification during to certain resistance, deashing executing agency begins to start deashing, and forms such as mechanical vibration cleaning, reverse gas cleaning are arranged.Another kind of for dust stratification on the filter bag outer wall (be called for short outer filter) when dust stratification during to certain resistance deashing executing agency begin to start deashing, forms such as mechanical vibration cleaning, reverse gas cleaning and compression ring slip deashing are arranged equally.No matter interior filter or outer filter will keep moving all the year round high efficiency key, except that filtrate material and deashing mechanism, whether the sack self-locking seal performance and the clean room that also depend primarily on filter bag have the grey dead angle of storage.And no matter sack cleaner is homemade or Japanese introducing equipment, and its filter bag sealing great majority are to adopt the method for hooped type or compression type to realize.The sealing of hooped type sack, its design feature is that sealing shroud is cylindrically by the upper end one ring convex tendon to be arranged, anti-lock ring and filter bag break away from, the sealing shroud welded and installed is above the card hole, the cover footpath is consistent with the card bore dia, filter bag opening is enclosed within the sealing shroud outside, with lock ring filter pocket mouths is fixed below the sealing shroud convex tendon then, and lock ring has kind forms such as spiral clip, steel wire anchor ear, pipe collar.The constructional aspect of compression type sack sealing also is that sealing shroud is cylindrical, and welded and installed is above the card hole, and the cover footpath is consistent with the aperture, after filter bag is enclosed within on the sealing shroud, with several bolts, pressing plate the sack of adjacent filter bag is compressed sealing around the card hole.More than the sealing device of two kinds of forms all exist following defective, the one, all become the grey dead angle of storage on the card between the adjacent seals cover and on the follower bolt, when changing filter bag again, the storage ash at place, dead angle can't be cleaned out, make the clean room long-pending have store up grey.The 2nd, filter pocket mouths is enclosed within the sealing shroud outside, hooped type all be the dust stratification place in the sealing shroud upper surface, constitute the fatigue district of dust stratification in the filter bag, this part serious wear shortens 2-3 doubly than the life-span of other parts of filter bag, maintenance and equipment cost are increased, the 3rd, the tired place of the dust stratification of filter bag becomes oozes the ash place.It remains the full state of ash, when patting deashing or reverse gas cleaning the dust in this district very easily the infiltrate filter bag enter the clean room, the reduction efficiency of dust collection.The 4th, filter pocket mouths is enclosed within the outer rear flank of big envelope, and no matter the hooped type compression type all need screw trip bolt, must reserve mounting distance between card hole and the card hole, the hole can not the too close dust removing effects that influences the card unit are, makes equipment volume and consumption steel material can not arrive optimum state.
The purpose of this utility model will provide the filter bag opening self-locking seal device of a nested structure uniqueness, can eliminate the defective that above-mentioned form exists, and the satisfied life-span of the filter bag that prolongs improves efficiency of dust collection, reduces equipment manufacturing cost, and the characteristics such as convenient of changing are installed.
The utility model is to realize like this, sealing shroud is by the cylindrical taper shape that changes into, the below is changed by top, card hole in the welded and installed position, flat spring ring with certain width thickness becomes tight fit with sealing shroud, ring spring is radially can be by flat, can flick after loosening, be convenient to put into sealing shroud, filter bag opening is put into from the card hole, sack turnup part is encasing inside and outside the ring spring, and the ring spring in the indentation sealing cover is stretched in sack on the inwall of cover, because cover is taper shape when filter bag work makes progress when stressed, it will be more and more tight cooperating between ring spring and jacket wall, realize the self-locking seal of sack.
In conjunction with the accompanying drawings the utility model is described in detail, accompanying drawing is the schematic cross-section of two work filter bags, the tiltedly tight cover 1 of sealing, it is conical, tapering is about 1:300, the small end internal diameter equates with the card hole, welded and installed is below the hole, the center in hole keeps concentric with tiltedly tight cover center, and for the tapering that improves the oblique tight cover 1 of self-locking effect sealing is bigger than lower semisection at nearly card jointing, the base is made circular-arc, bottom outlet can with the card hole general big also can be greater than the card hole, tiltedly the height of tight cover can be at 50～100mm, and wall thickness is not less than 3mm, and material can be identical with the card material.Self-locking tension spring 2 is ring spring, that encircles radially can be by flat, loosen then and flick, be tight fit with the inwall that tiltedly tightly overlaps 1, be convenient to install and guarantee to have certain tension force again, 2 width can be at 18～35mm, thickness is at 03～09mm, make with metal spring sheet material material, the sack of filter bag 5 is put in the hole of card 3, after turnup partly encases self-locking tension spring 2, sack is stretched on the inwall of oblique tight cover 1, for reducing the filter bag wearing and tearing and improving sealing, tension spring 2 and oblique tight cover 1 fit clearance pad one deck sealing soft formation 4, filter bag 5 serves as a contrast cloth or the plastics that the wear-resisting bed course 6,4 of one deck and 6 is all used wear-resisting softness with card 3 fit clearances, because the tiltedly tight cover 1 of sealing is conical, filter bag work makes progress when stressed, and tension spring 2 is opened more and more tightly to jacket wall sack, realizes the sack self-locking seal.
The utility model, can realize that the deduster clean room does not have the grey dead angle of storage, nos dust stratification place also just makes filter bag not have tired place and oozes the ash place in the filter bag, has improved efficiency of dust collection, and install, to change filter bag easy to operate, the filter opening density of card can increase, can reduce equipment volume under the same efficiency, save the labour, life of bag filter prolongs, be the ideal device that a kind of deduster is realized the filter bag sealing, have the meaning of promoting the use of.
