Abstract

The invention relates to a filter-bag protective device for injecting pulse air flow of a bag-type dust collector, comprising a sleeve, reinforcing ribs, a first hoop ring and a second hoop ring, wherein the reinforcing ribs are fixed in the inner sides of the first hoop ring and the second hoop ring; the sleeve passes through the first hoop ring and the second hoop ring vertically under the support of the reinforcing ribs; the diameter of the first hoop ring is greater than that of a bag cage; and the diameter of the second hoop ring is less than that of the bag cage. The filter-bag protective device can achieve the purposes of protecting a bag mouth of a filter bag and prolonging the service life of the filter bag by only needing to be rack-mounted on a cage mouth of the original bag cage, does not need to replace the original bag cage, has little investment and small air-flow resistance when in the filtering work, and also has 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 present invention relates to sack cleaner corollary apparatus field, particularly relate 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 by this invention 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 solution adopted for the present invention to solve the technical problems 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 present invention compared with prior art; have following advantage and good effect: the present invention 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 present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiments of the present invention relate 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.
Frame of the present invention 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 present invention need not to change former marsupial cage, and small investment is installed simple, convenient.
