Abstract
The invention discloses a novel zero-leakage smoke baffle isolation door which comprises a wind door frame, blades arranged on the inner side of the wind door frame and a pneumatic assembly arranged in the middle of the wind door frame, wherein the pneumatic assembly is used for driving the blades to be opened and closed.
Description
Technical Field
The invention relates to the field of air door processing, in particular to a novel zero-leakage smoke baffle isolation door.
Background
Baffle air door mainly is applied to the buggy pipeline of trades such as power plant's coal mine metallurgy chemical industry, mainly plays the effect that keeps off the wind powder, and the medium mainly includes the air flue gas, hot-blast and wind powder mixture, and current baffle air door is mostly single blade and bilobed structure, and bilobed sealing nature is relatively poor, and the pure mechanical drive of current single blade, the angle of opening and shutting is little, starts slowly, and the fault rate is higher and the precision of switching is low, can't realize accurate transport control demand.
Disclosure of Invention
In view of the above technical problems, the present invention provides a novel zero-leakage flue gas baffle isolation door, comprising:
the pneumatic assembly is used for driving the blades to be opened and closed, the pneumatic assembly comprises a pneumatic actuator, a first transmission shaft connected with the pneumatic actuator, a second transmission shaft connected with the first transmission shaft, a containing cavity used for containing the second transmission shaft, a third transmission shaft arranged in the containing cavity, an inflatable air bag used for linking the third transmission shaft, a transmission bearing arranged on the third transmission shaft, a bearing support used for installing the transmission bearing, a shaft seal sleeved on the third transmission shaft and an inflation pipeline used for inflating the inflatable air bag, and an opening degree indicator is arranged on the outer side of the wind door frame.
Preferably, an air passage is arranged on the third transmission shaft.
Preferably, a bearing seat is installed on the second transmission shaft.
Has the advantages that:
1. the single-blade design is adopted, the sealing problem caused by the middle gap of the double blades is effectively solved, and real zero leakage is realized.
2. Adopt pneumatic component, the design of three transmission shafts of cooperation, it is more steady to open and shut, compares in mechanical drive, and the striking of blade and wind door frame reduces by a wide margin to effectively reduce the fault rate.
3. The opening and closing indication is arranged, so that the opening and closing angle can be conveniently monitored, and the accurate control performance is greatly improved.
