Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
Reference picture 1-3, a kind of high-purity calcium hydroxide production centrifugal fan, including ventilated enclosure 1 and it is fixed on it
Bottom support bracket, air inlet 2 and air outlet 4 are respectively equipped with ventilated enclosure 1, and side of the ventilated enclosure 1 away from air inlet 2 is provided with electricity
Machine 9, the output end of motor 9 are connected with rotating shaft 6, and the side wall of ventilated enclosure 1 is run through in the one end of rotating shaft 6 away from motor 9, in rotating shaft 6
Impeller 3 is socketed with, impeller 3 is located in ventilated enclosure 1, mounting cylinder 5 is provided with the opening's edge of air inlet 2, mounting cylinder 5 is away from ventilation blower
The inwall of the side of shell 1 is provided with filter bag 7, and the inwall of mounting cylinder 5 is rotatably connected to the straight-bar 11 of V-type bar 10 and first, V-type bar respectively
10 are connected close to one end of filter bag 7 with filter bag 7.
First one end of straight-bar 11 away from mounting cylinder 5 is provided with slot, and the inner bottom part of slot is connected with second by spring 12
Straight-bar 13, the one end of the second straight-bar 13 away from spring 12 is be hinged with V-type bar 10, and the number of the second straight-bar 13 is two, and two
