Abstract
Prevent flowing backward dust removal filter, including fan and filter, the air intake of filter is connected to the air outlet of fan, the air outlet of filter is air pipe's one end even, the other end tip of tuber pipe set up with mouth of pipe complex chock plug, the one end of installation connecting rod on the chock plug, the other end of connecting rod stretches into to the tuber pipe in and sets up the pressure disk, sets up the inner ring in the tuber pipe, the inner ring lies in the middle part of connecting rod, sets up the spring between the interior ring sum pressure disk. The utility model discloses when using, it is ejecting with the chock plug through air pressure, can realize airing exhaust, during the shut down, the chock plug restores to the throne under the effect of spring, places the bird and gets into, effectively protects the safety of life safety and the equipment of bird.
Description
Technical field
This utility model belongs to field of environmental engineering, specifically a kind of reverse-filling dust removal filter.
Background technology
The exhaust duct of dust removal filter is positioned at outdoor.Easily becoming bird to enter as interim nest at exhaust duct, the most even can nest, once unlatching can make bird get a fright, and even threatens the life of bird.Bird drains in exhaust duct, and bird feces has corrosiveness to exhaust duct.
Utility model content
This utility model provides a kind of reverse-filling dust removal filter, in order to solve defect of the prior art.
This utility model is achieved by the following technical programs:
Reverse-filling dust removal filter, including blower fan and filter, the air outlet of blower fan connects the air inlet of filter, the air outlet of filter connects one end of airduct, and the other end end of airduct arranges the chock plug coordinated with the mouth of pipe, one end of installing connecting rods on chock plug, the other end of connecting rod stretches in airduct and arranges platen, arranging internal ring in airduct, internal ring is positioned at the middle part of connecting rod, arranges spring between internal ring and platen.
Reverse-filling dust removal filter as above, the periphery of described blower fan arranges mounting flange.
The utility model has the advantages that: chock plug in use, is ejected by this utility model by air pressure, it is possible to realize air draft；During shutdown, chock plug resets under the action of the spring, places bird and enters, and effectively protects life security and the safety of equipment of bird.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is this utility model structural representation.
Reference: 1 flange 2 blower fan 3 filter 4 airduct 5 platen 6 spring 7 internal ring 8 connecting rod 9 chock plug.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Reverse-filling dust removal filter, as shown in Figure 1, including blower fan 2 and filter 3, the air outlet of blower fan 2 connects the air inlet of filter 3, and the air outlet of filter 3 connects one end of airduct 4, the other end end of airduct 4 arranges the chock plug 9 coordinated with the mouth of pipe, one end of installing connecting rods 8 on chock plug 9, in the other end of connecting rod 8 stretches to airduct 4 and arrange platen 5, arranges internal ring 7 in airduct 4, internal ring 7 is positioned at the middle part of connecting rod 8, arranges spring 6 between internal ring 7 and platen 5.Chock plug in use, is ejected by this utility model by air pressure, it is possible to realize air draft；During shutdown, chock plug resets under the action of the spring, places bird and enters, and effectively protects life security and the safety of equipment of bird.Installing for convenience, the periphery of described blower fan 2 arranges mounting flange 1, and flange 1 can coordinate with the vent that Factory Building etc. is built.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
