Preferably: the reducing pipeline A is changed from big to small, and the reducing pipeline B is changed from small to big.
Preferably, the following components: smoke exhaust equipment for fire engineering is still including connecting plate, check valve board, top air pipe, rotation turbine and the blade of airing exhaust, the connecting plate is installed at the air pipe top, install the check valve board on the connecting plate, top air pipe is installed at check valve board top, rotation turbine is installed at top air pipe top, install the blade of airing exhaust in the rotation turbine.
The utility model has the advantages that: the utility model discloses it is rational in infrastructure, air pipe between air intake and the air exit all is connected through the reducing pipeline for air speed grow in the air pipe can discharge fume fast, and the one-way valve plate has been seted up at the air pipe top simultaneously and has been connected with top air pipe, and drives the daily ventilation work of the blade completion of airing exhaust through rotating the turbine.
Drawings
Fig. 1 is the structure schematic diagram of the smoke exhaust device for fire engineering of the utility model.
In the figure: 1. the air inlet, 2, reducing pipelines A and 3, a ventilation elbow, 4, a ventilation pipeline, 5, reducing pipelines B and 6, an air outlet, 7, an axial flow fan, 8, a connecting plate, 9, a one-way valve plate, 10, a top ventilation pipeline, 11, a rotating turbine, 12 and an air exhaust blade.
Detailed Description
The invention will be further elucidated with reference to the following figures and specific embodiments:
as shown in fig. 1, a fume extractor for fire engineering, including air intake 1, reducing pipeline A2, ventilation elbow 3, air pipe 4, reducing pipeline B5, air exit 6, axial fan 7, reducing pipeline A2 is installed at 1 top of air intake, ventilation elbow 3 is installed at reducing pipeline A2 top, ventilation elbow 3 is connected with air pipe 4, reducing pipeline B5 is installed to air pipe 4 front end, air exit 6 is installed to reducing pipeline B5 front end, axial fan 7 is installed to the interior of air exit 6. The reducing pipeline A2 is changed from big to small, and the reducing pipeline B5 is changed from small to big. Smoke exhaust device for fire engineering is still including connecting plate 8, check valve board 9, top air pipe 10, rotation turbine 11 and air exhaust blade 12, connecting plate 8 is installed at air pipe 4 top, install check valve board 9 on the connecting plate 8, top air pipe 10 is installed at check valve board 9 top, rotation turbine 11 is installed at top air pipe 10 top, install air exhaust blade 12 in the rotation turbine 11.
The utility model discloses a theory of operation: air intake 1 is connected with ventilation elbow 3 and air pipe 4 through reducing pipeline A2, and air pipe 4 is connected with air exit 6 through reducing pipeline B5, makes air speed flow in the air pipe become fast through the reducing pipeline, conveniently looses smog fast, and the air pipe 10 at top drives exhaust blade 12 through rotating turbine 11 simultaneously and can realize daily ventilation operation through check valve plate 9.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The embodiments are therefore to be considered in all respects as illustrative and all changes which come within the meaning and range of equivalency are therefore intended to be embraced therein.
