Abstract
The utility model relates to a sealing device used for a failed filter bag of a bag (or electric-bag) type dust precipitator, in particular to a sealing shield of a filter bag. The sealing shield of the filter bag is arranged above a failed filter bag of a precipitator, and is characterized in that a compression spring, a sealing cover and a sealing ring are included, wherein the sealing ring is arranged on an embossed plate at a filter-bag opening; the sealing cover is arranged in the sealing ring; and the compression spring is arranged at the top of the sealing cover, one end of the compression spring is arranged on the sealing cover, and the other end of the compression spring is arranged in a spray-blast pipe of the model. The sealing shield has the advantages of convenience for operation, good sealing property, and economization of maintenance cost.
Description
Technical field
The utility model relates to a kind of sealing device that is used for cloth bag (or electricity bag) deduster inefficacy filter bag.
Background technology
Cloth bag (or electricity bag) deduster is in the life cycle of filter bag, and a spot of filter bag damage is not to adopt the way of changing, but etc. the broken bag number acquire a certain degree, all change again.This is because the gas permeability of new filter bag is fine, and when mixing use with old filter bag, the new filter bag rate of filtration reaches more than the several times of old filter bag.This filters the filter opening that dust in flue gas stream can very fast obstruction filter bag, makes the gas permeability of new filter bag drop to the level identical with old filter bag.The benefit that adopts the filter bag seal closure is the expense that has not only reduced to change the workload of bag but also reduced to change bag.
Prior art is behind filter bag damage at present, takes to extract out the filter bag that lost efficacy under the card usually, and garden shape stifle plate greater than filter bag aperture 20 millimeter of welding comes shutoff on this card hole.Like this when life of bag filter is final, integral body more also need be cut off the stifle plate before the filter bag, be difficult to guarantee the requirement of card hole flatness and roughness in the general gas cutting operation, often because the card hole applying imprecision reason of new filter pocket mouths and shutoff easily causes the generation of flue gas leakage phenomenon.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and filter bag seal closure that a kind of easy to operate, good seal performance, saving maintenance cost are provided.
The technical scheme in the invention for solving the above technical problem is: this filter bag seal closure, be arranged on the inefficacy filter bag top of deduster, it is characterized in that: comprise compression spring, seal cover and sealing ring, described sealing ring is arranged on the card of filter pocket mouths, seal cover is arranged in the sealing ring, the seal cover top is provided with the compression spring, and compression spring one end is arranged on the seal cover, and the compression spring other end is arranged in the winding-up pipe of deduster.
Compression both ends of the spring diameter difference described in the utility model, large diameter this end are pressed and are placed on the seal cover, and this end of minor diameter is inserted in the winding-up pipe of deduster.
Sealing ring described in the utility model is placed on the card.
Sealing ring described in the utility model comprises inside and outside two-layer, leaves clip slot between the internal layer skin.
Be fitted with seal cover in the sealing ring clip slot described in the utility model, seal cover covers whole filter pocket mouths.
The utility model compared with prior art has the following advantages: sealing ring described in the utility model directly is placed on the card, be provided with seal cover in the sealing ring, seal cover is provided with the compression spring, rely on the elastic force of compression spring, firmly withstand on the card seal cover, thereby make that whole filter pocket mouths is sealed, sealing ring and seal cover have guaranteed the sealing of filter pocket mouths.Because just contact is not and fixing each other for sealing ring, seal cover, spring and card, therefore installation and removal are all very convenient, saved maintenance cost, improved efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, the utility model is arranged on inefficacy filter bag 6 tops of deduster, comprises compression spring 1, seal cover 2 and sealing ring 3, and described sealing ring 3 is placed on the card 4, sealing ring 3 comprises internal layer 32 and skin 31, leaves clip slot 33 between the internal layer 32 and outer 31.Be fitted with seal cover 2 in the clip slot 33, seal cover 2 covers whole filter pocket mouths 5.Seal cover 2 tops are provided with compression spring 1, compression spring 1 two ends diameter difference, large diameter this end is placed on the seal cover 2, this end of minor diameter is inserted in the winding-up pipe 7 of deduster, rely on the elastic force of compression spring 1, make seal cover 2 firmly withstand card 4, thereby make whole filter pocket mouths 5 sealings by sealing ring 3.
When the deduster repair and maintenance, above inefficacy filter bag 6, as shown in Figure 1, sealing ring 3 in place according to this, seal cover 2 and compression spring 1, with shutoff flue gas stream.When deduster integral body needs to upgrade filter bag, successively remove compression spring 1, seal cover 2 and sealing ring 3, change filter bag then.Because all be to contact and fixing between compression spring 1, seal cover 2, sealing ring 3 and the card 4, it is convenient therefore to change, maintenance cost is low.
In addition; need to prove, the specific embodiment described in this specification, its each several part titles etc. can be different; allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
