Abstract
The utility model discloses a kind of conical screen with check function.The utility model is combined by multiple conical filter pieces and triangle non-return piece, multiple conical filter pieces connect together to form cone filter screen, multiple triangle non-return pieces are along cone filter screen outer peripheral face arrangement covering cone filter screen outer peripheral face, described each conical filter piece and triangle non-return piece carry fixed flange, and conical filter piece and triangle non-return piece are assemblied in one by ring flange.Conical screen of the utility model with check function can reduce the use of check-valves, saving construction cost cost by using triangle non-return piece.
Description
Technical field
The utility model is related to HVAC ventilation field, more particularly to a kind of air filter screen.
Background technology
Ajutage includes fresh air ajutage, mixed ventilation pipe.The fine or not direct relation of air quality before the room of entrance
To the quality of space air quality, the wind in room is sent into added with air cleaner, when blower fan is out of service, to prevent room
Inside causes pressure to become big so that house interior air enters Gas inlet tube and dispels often the impurity in filter because of other reasonses
Often increase check-valves, increase check-valves and increase cost, must be interrupted when being cleaned simultaneously for current air cleaner
The operation of system, ensureing the reliability service of system while being reduces cost again needs a kind of filter.
Utility model content
The utility model is to overcome weak point of the prior art, there is provided a kind of taper filter with check function
Net.
The utility model is achieved through the following technical solutions:
A kind of conical screen with check function, is combined by multiple conical filter pieces and triangle non-return piece, multiple
Conical filter piece is connected together to form cone filter screen, and multiple triangle non-return pieces are arranged along the cone filter screen outer peripheral face and covered
Cone filter screen outer peripheral face, described each conical filter piece and triangle non-return piece carry fixed flange, conical filter piece and
Triangle non-return piece is assemblied in one by ring flange.
The conical filter piece is made using stainless steel mesh filter screen or bouffancy filter paper, and triangle non-return piece is not using
Rust steel thin slice is made.
Compared with prior art, the beneficial effects of the utility model are：
1st, conical screen of the utility model with check function uses taper structure design so that assembling is simple, cleaning side
Just.
2nd, directly be loaded on filter screen inside airduct by bolt hole by conical screen of the utility model with check function so that
Dust-proof treatment is carried out during cleaning filter screen to system simple, filter core is taken out during cleaning and connects airduct.
3rd, conical screen of the utility model with check function can reduce check-valves by using triangle non-return piece
Use, saving construction cost cost.
Brief description of the drawings
Fig. 1 is the assembling figure of conical screen of the utility model with check function;
Fig. 2 is the structure chart of the conical filter piece of conical screen of the utility model with check function;
Fig. 3 is structure chart when the triangle non-return piece blower fan of conical screen of the utility model with check function stops;
Fig. 4 is structure chart when the triangle non-return piece blower fan of conical screen of the utility model with check function is opened.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The structure chart of conical screen of the utility model with check function as shown in Figure 1,2,3, 4, the cone with check function
Shape filter screen, mainly by multiple conical filter pieces（Fig. 2）And triangle non-return piece（Fig. 3,4）Combine, conical filter piece can be adopted
It is made with stainless steel mesh filter screen or bouffancy filter paper, triangle non-return piece is made using multi-disc stainless steel thin slice 4, many
Individual conical filter piece connects together to form cone filter screen, and multiple triangle non-return pieces cover along cone filter screen outer peripheral face arrangement
Lid cone filter screen outer peripheral face, described each conical filter piece and triangle non-return piece carry fixed flange 2, conical filter piece
And triangle non-return piece is assemblied in one by ring flange, the conical filter piece group 5 and triangle non-return piece 4 pass through flange hole
3 combinations, and fixedly mounted by flange hole 3 and airduct.
When blower fan is opened, in the presence of blast, the multi-disc stainless steel thin slice 4 of triangle non-return piece is opened, and forms such as Fig. 4
When state, send into room wind enter strainer filtering after send into room, when blower fan is out of service, the multi-disc of triangle non-return piece is not
Rust steel thin slice 4 is closed, and forms state during such as Fig. 3, can now prevent the wind in room from entering Gas inlet tube.
The above is only preferred embodiment of the present utility model, it is noted that general for the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch also to should be regarded as protection domain of the present utility model.
Claims (2)
