Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
Embodiment 1
As shown in Figure 1, a kind of waste gas dust suction cover, including the cylindrical dust hood main body 1 laterally set, dust hood main body 1
Lower part sets gradually several air inlets 2 along its length, and 2 edge of air inlet connects the auxiliary of oriented 2 outer rim of air inlet connection
Cover 7.The column 3 through 1 lower part of dust hood main body is both provided among each two air inlet 2, column 3 can be moved up and down and stopped
Lean against 1 lower part certain position of dust hood main body.Wind shield 4 is provided on column 3, wind shield 4 is located inside dust hood main body 1,
4 both sides of wind shield extend to the air inlet 2 that can block 3 both sides of column.
External screw thread is provided on column 3, is socketed with outside column 3 and is located at suction with 3 matched nut 31 of column, nut 31
Outside dust hood main body 1.
The top of dust hood main body 1 has been uniformly arranged several air outlets 8, and the spacing between air outlet 8 is 1.5m~2m.Outlet air
Valve 9 is both provided on mouth 8.
In embodiment 1, by 31 adjusting post 3 of rotating nut can make wind shield 4 move up and down in addition block completely into
Air port 2, so as to adjust 2 size of air inlet, to adapt to different gas inlet amounts.
Embodiment 2
Such as Fig. 2 to Fig. 4, embodiment 2 and 1 structure of embodiment are essentially identical, the difference is that the lower section of dust hood main body 1 in
Column 3 is provided outside connector 11, and connector 11 is made of two opposite arc-shaped risers 12 set up, on two risers 12 from
It is above past to be arranged with several corresponding circular holes 13；Be provided with from top to bottom on column 3 it is several through 3 screw hole 32 of column, it is firm
Bolt 51 is fixed on by firm nut 52 on connector 11 after passing through circular hole 13 and screw hole 32.
In embodiment 2, firm bolt 51 is inserted into different circular hole 13 and screw hole 32, can up and down adjustment column 3 position
It puts, wind shield 4 moves up and down therewith, so as to adjust 2 size of air inlet.
Embodiment 3
As shown in Figure 5 and Figure 6, embodiment 3 and 1 structure of embodiment are essentially identical, the difference is that 3 outside of column is set
There is spring 61,61 top of spring is fixedly connected with 4 lower part of wind shield, and 61 lower part of spring is fixed with 1 lower inside of dust hood main body
Connection, column 3 are connected with cross bar 62 in the end of 1 outside one end of dust hood main body, and 62 other end end of cross bar is connected with hook
63。
In embodiment 3, it will link up in 63 fixed links for hanging over the external different heights set or on other fixed mechanisms, it can
Vertical columns 3 move up and down position, and wind shield 4 moves up and down therewith, so as to adjust 2 size of air inlet.Compared to embodiment 1
With embodiment 2, embodiment 3 in use, is also capable of the position of adjusting post 3 immediately, because hook 63 is in relatively distant
Put, can to avoid 1 lower section flue dust of dust hood main body it is excessive do not see with temperature it is excessively high bring the drawbacks of cannot adjusting.
The utility model can make to move down on wind shield 4 according to exhaust gas and smoke amount size, the upper-lower position of adjusting post 3
It moves and is fixed on certain altitude, so as to adjust 2 intake size of air inlet.When exhausted air quantity is big, column 3 is moved up, is kept out the wind
Plate 4 and the distance of 1 lower part of dust hood main body increase, the air inflow increase of air inlet 2.When exhausted air quantity is small, column is moved down
3, wind shield 4 and the distance of 1 lower part of dust hood main body reduce, and the wind turbine being connected with the utility model is adjustable to smaller gear
Also the exhaust gas of 1 lower part of dust hood main body can be fully absorbed, saves energy consumption.
When some air inlets 2 need not be used, by moving down column 3, corresponding air inlet 2 can be closed, can also close phase
The valve 9 on air outlet 8 is answered, so as to more subtly adjust the air inflow of the utility model according to exhaust gas position, exhausted air quantity.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, it all should be in the protection domain being defined in the patent claims.
