The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises fixed frame 1, filter 2 and axial flow blower 3 three parts.The assembly of these three parts is installed on the blower fan tower barrel, realizes the interior separate ventilation of tower tube.This assembly can be directly installed on the tower barrel, but preferably is installed on the tower tube door body 4, so comparatively makes things convenient for the dismounting of device.
As Fig. 1, shown in Figure 3, as a kind of embodiment, at first perforate on tower tube door body 4 is equipped with flange body 5, and flange body 5 centers have perforate, and the edge has bolt hole.Be connected and fixed frame 1 by bolt on the flange body 5.Fixed frame 1 is the shell structure of a cavity, all do the edge 11,12 (as shown in Figure 4) that turns up at the both ends of housing, offer bolt hole on each edge, fixed frame 1 utilizes an end edge 11 to be installed on the flange body 5, utilizes other end edge 12 that filter 2 is installed.After installing flange body 5 and filter 2, it is penetrating that the cavity of fixed frame 1 still keeps.After fixed frame 1 is installed on the flange body 5, an end of filter 2 is stretched to outside the tower tube.Fixed frame 1 was will be respectively except that the shape at two ends corresponding with filter 2 and flange body 5, all the other position shapes were unrestricted, and common shape has square (as shown in Figure 5), cylindrical shape at the bottom of the tip circle, square tube shape etc.
In the foregoing description, also fixed frame 1 can be welded direct to the tapping of tower tube door body 4,, cancel the edge 11 of fixed frame 1 one ends simultaneously so far without flange body 4.
In the foregoing description, the connected mode of fixed frame 1 and filter 2 also can adopt the mode of inserted installation, slots on fixed frame 1 edge, and filter 2 is inserted in the fluting, so far cancels the edge 12 of fixed frame 1 other end.
As shown in Figure 1, an axial flow blower 3 inwardly is installed on tower tube door body 4, the cavity of the air port of axial flow blower 3 and fixed frame 1 is over against, the circulation of assurance wind.Axial flow blower 3 can be polytype, and as diagonal flow fan, high-pressure shaft flow fan, flow-mixing blower fan etc., concrete mounting means can be determined according to the concrete type of attachment of blower fan.Under the situation that flange body 5 is installed, axial flow blower 3 can be installed on the flange body 5 by bolt; Under the situation that does not have mounting flange body 5, axial flow blower 3 can be fixed on the body by carriage etc., and form is not only
The utility model middle filtrator 2 can be polytype, imitate serial filter (type roughing efficiency air filter capable of washing, disposable roughing efficiency air filter), medium effeciency filter (pocket type medium effeciency filter, box medium effeciency filter), high efficiency particulate air filter (dividing plate high efficiency particulate air filter, no dividing plate high efficiency particulate air filter are arranged), various types of filtration cotton etc. as before, to adapt to the environment of different salt alkali contents, its concrete form can carry out respective design as the case may be.
Ventilation filter of the present utility model can be installed a cover, two covers or many covers on the tower tube, as shown in Figure 1, the such device of two covers just has been installed simultaneously on tower tube door body 4.
What deserves to be explained is, the structure of each above-mentioned parts, connected mode are not unique, such as being the connection of flange body bolt, can be in advance fixed frame 1, filter 2 and axial flow blower 3 to be made of one, integral body be welded on door body or barrel, but which kind of form no matter, as long as guarantee that filter is outside tube, blower fan is in tube, and is penetrating between filter and the blower fan, realizes filtering the such function of ventilation and gets final product.Therefore, the various embodiments described above only are used to illustrate the utility model, and every equivalents of carrying out on the basis of technical solutions of the utility model and improvement all should not got rid of outside protection domain of the present utility model.
During work, open axial flow blower 3, exhausting in the tower tube, outside sea wind wants to enter in the tube, must filter through filter 2 earlier, could exchange with the air of the inside then.After salt and alkali component that is mingled with in the sea wind and dust storm particle etc. are filtered device 2 filtrations, guaranteed the environmental drying cleaning of tower tube inside.
