Abstract

The utility model relates to a filter bag protection device for blowing of pulse airflow of a bag-type dust collector, which comprises a casing pipe, reinforcing ribs, a first tension band and a second tension band. The reinforcing ribs are fixed on the inner sides of the first tension band and the second tension band; the casing pipe supported by the reinforcing ribs penetrates through the first tension band and the second tension band; the diameter of the first tension band is larger than that of a bag cage; and the diameter of the second tension band is smaller than that of the bag cage. The filter bag protection device can achieve the purposes of protecting a bag opening of a filter bag and prolonging the service life of the filter bag by being mounted on a cage opening of an original bag cage without replacing the original bag cage, and has the advantages of small investment, small airflow resistance in filtering work, and simple and convenient installation.

Description

A kind of filter-bag protective device for injecting pulse air flow of bag-type dust collector
Technical field
The utility model relates to sack cleaner corollary apparatus field, particularly relates to a kind of filter-bag protective device for injecting pulse air flow of bag-type dust collector.
Background technology
At present the sack cleaner purge mode adopts the pulse of compressed air purge mode mostly, and by high-voltage high-speed airflow is sprayed into filter bag, air-flow effect filter bag produces swollen vibration and the air-flow of contracting and flows through filter bag impact dust layer, reaches ash-removal effect.In the present sack cleaner, the filter bag opening position does not add safeguard measure, and action of high-speed airflow can cause filter bag opening position mechanical damage, shortens life-span of the filter bag, and shown in Figure 1 is the bag cage that does not add safeguard measure.In order to tackle this problem; routine techniques is to install the casing protection filter bag additional at the import position of bag-type duster filtering bag liner bag cage not to be damaged; shown in Figure 2 is the bag cage that routine installs the casing protection device additional; gas-flow resistance when the work of filtration is big but this mode causes bag-type duster filtering bag, and energy consumption increases.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of filter-bag protective device for injecting pulse air flow of bag-type dust collector, on the basis of not changing bag cage, reaches the purpose of protection filter bag opening, and gas-flow resistance is little when filtering work, installs simple, convenient.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of filter-bag protective device for injecting pulse air flow of bag-type dust collector is provided, comprise sleeve pipe, reinforcement, first cranse and second cranse, described reinforcement is fixed on the inboard of described first cranse and second cranse; Described sleeve pipe vertically passes described first cranse and second cranse under described reinforcement supports; The diameter of described first cranse is greater than the diameter of bag cage; The diameter of described second cranse is less than the diameter of bag cage.
The reinforcement of second cranse of described filter-bag protective device for injecting pulse air flow of bag-type dust collector and described bag cage near.
The sleeve pipe of described filter-bag protective device for injecting pulse air flow of bag-type dust collector is a hourglass shape.
Beneficial effect
Owing to adopted above-mentioned technical scheme; the utility model compared with prior art; have following advantage and good effect: the utility model only needs frame to be contained on the cage mouth of former bag cage; the purpose that just can reach the protection filter bag opening and prolong life-span of the filter bag; and need not to change former marsupial cage; small investment, when filtering work gas-flow resistance little, install simple, convenient.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present utility model relates to a kind of filter-bag protective device for injecting pulse air flow of bag-type dust collector; as described in Fig. 3 and Fig. 4; comprise sleeve pipe 1, reinforcement 2, first cranse 3 and second cranse 4; described reinforcement 2 is fixed on the inboard of described first cranse 3 and second cranse 4, and described sleeve pipe 1 passes described first cranse 3 and second cranse 4 under described reinforcement 2 supports.Wherein, the diameter of described first cranse 3 can be contained on the cage mouth of bag cage 5 by frame this filter-bag protective device for injecting pulse air flow of bag-type dust collector greater than the diameter of bag cage 5; The diameter of described second cranse 4 makes this filter-bag protective device for injecting pulse air flow of bag-type dust collector first cranse 3 can be packed bag cage 5 into the lower part in less than the diameter of bag cage 5.If the diameter of second cranse 4 is just slightly less than the diameter of bag cage 5,, thereby guarantee that sleeve pipe 1 keeps vertical state just second cranse 4 can be near the reinforcement of living bag cage 5 so.Described sleeve pipe 1 adopts the hourglass shape design.
The utility model frame is contained on the cage mouth of bag cage, when carrying out deashing work, as shown in Figure 5; the winding-up air-flow sprays into sleeve pipe 1, and the inducing peripheral air forms induced draft simultaneously, compares with the bag cage (shown in Figure 1) that protective device is not housed; can effectively protect the sack of filter bag, prolong life-span of the filter bag.When the work of filtration, as shown in Figure 6, purifying gas flow enters the pure qi (oxygen) casing simultaneously inside and outside sleeve pipe 1, compares with the bag cage (shown in Figure 2) that installs the casing protection device additional, and the resistance of air-flow is littler.In addition, the utility model need not to change former marsupial cage, and small investment is installed simple, convenient.
