Abstract
The utility model relates to a kind of environmental protection machinery technical field, is specifically related to a kind of dedusting filtering bag net.Comprise outer shroud and rack, described outer shroud is connected by spring and rack, and described outer shroud is provided with retractor device.The utility model is by arranging retractor device and spring on the net at filter bag, thus make filter bag net can adapt to the filter bag of different size, effectively raise the flexibility of filter bag net, the filter bag net simultaneously arranged effectively can avoid again the phase mutual friction of filter bag, effectively raise the service life of filter bag, reduce production cost.
Description
Technical field
The utility model relates to a kind of environmental protection machinery technical field, is specifically related to a kind of dedusting filtering bag net.
Background technology
Filter bag is the key component in sack cleaner running, and usual cylinder type filter bag is vertically suspended in deduster.Fabric and the design of filter bag should be pursued high efficiency filter as far as possible, be easy to dust stripping and effect durable in use.
In use, because dust-contained airflow becomes eddy flow shape access arrangement casing, filter bag is in contorted under airflow function, and the easy so mutual wearing and tearing causing filter bag, prior art does not also have a kind of device effectively to address this problem for existing filter bag.
Utility model content
The purpose of this utility model is the defect for above-mentioned prior art, and provide a kind of dedusting filtering bag net, it can adapt to the filter bag of different size, effectively avoids filter bag friction each other, and then effectively improves the service life of filter bag.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of dedusting filtering bag net, comprise outer shroud and rack, described outer shroud is connected by spring and rack, and described outer shroud is provided with retractor device.By arranging retractor device and spring on filter screen, making filter screen can adapt to the filter bag of various sizes, effectively avoiding the wearing and tearing of filter bag, and then improve the service life of filter bag.
As further improvement of the utility model, the grid lattice point of rack described in it is welded with iron hoop.By welding iron hoop on rack, effectively can limit the flow velocity of dust, avoiding the contact of dust and filter bag inner surface, effectively reducing the wearing and tearing of filter bag, and then improve the service life of filter bag.
As further improvement of the utility model, retractor device described in it comprises shell, pullover and fastening bolt, described fastening bolt be installed on pullover on.Its fastening bolt arranged effectively can limit the radius of outer shroud, adapts to the filter bag of different size, improves the adaptability of filter bag net, effectively reduce production cost.
As further improvement of the utility model, the lateral wall of outer shroud described in it adopts wedge angle groove.It effectively can improve the frictional force of outer shroud and filter bag at the wedge angle groove that outer shroud lateral wall is arranged, and makes filter bag net to be more firmly placed in filter bag.
The utility model is by arranging retractor device and spring on the net at filter bag, thus make filter bag net can adapt to the filter bag of different size, effectively raise the flexibility of filter bag net, the filter bag net simultaneously arranged effectively can avoid again the phase mutual friction of filter bag, effectively raise the service life of filter bag, reduce production cost.

Fig. 2 represents the sectional structure schematic diagram of outer shroud shown in Fig. 1;
In figure: 1, pullover; 2, outer shroud; 3, fastening bolt; 4, rack; 5, spring; 6, iron hoop; 7, retractor device; 8, shell; 9, wedge angle groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
A kind of dedusting filtering bag net as shown in Figure 1, it comprises outer shroud 2 and rack 4, outer shroud 2 is connected by spring 5 and rack 4, and outer shroud 2 adopts elastic rubber material, and the end of outer shroud 2 inserts in retractor device 7, pullover 1 of retractor device 7 is provided with fastening bolt 3, by pressing outer shroud 2, the radius of outer shroud 2 is changed, by the radius regulating fastening bolt 3 to control outer shroud 2, thus realize the filter bag of filter bag net adaptation different size, the grid lattice point of rack 4 is welded with iron hoop 6.Outer shroud 2 as shown in Figure 2, its lateral wall adopts wedge angle groove 9, the pointed design of wedge angle groove 9, increase effectively outer shroud 2 and the contact area of filter bag madial wall, effectively ensure that filter bag net can firmly be placed in filter bag.
When the utility model comes into operation, by pressing outer shroud 2, then by regulating fastening bolt 3, thus adjusting the radius adapting to corresponding filter bag, then filter bag net being placed in filter bag.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technology people of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
