[detailed description of the invention]
The structure of the embodiment of the present invention 1 rotary sieve as shown in Figures 1 to 9, comprise filter screen and rotating disk, rotating disk is dish type fan, and dish type fan comprises wheel rim 1, wheel hub 2 and multiple fan blade 3, wheel rim 1 is connected by fan blade 3 with wheel hub 2, and dish type fan corrosion resistant plate is made as base material punching press.
The periphery of wheel rim 1 has 120 circumferentially uniform heel teeths 101, and there are 40 circumferentially uniform wire-hanging hooks 201 in the front of wheel hub 2, and there are 40 circumferentially uniform wire-hanging hooks 202 at the back side of wheel hub 2.That is, the quantity of heel teeth 101 is 3 times of wire-hanging hook 201 quantity, is 3 times of wire-hanging hook 202 quantity equally.
There is a male cone (strobilus masculinus) position contiguous with heel teeth 101 of wheel rim 1, and the bus of male cone (strobilus masculinus) and the angle of rotating disk principal plane (plane of rotation) are 15-30 °.
Two kinds of filaments that filter screen is divided into thickness different, in the present embodiment, the diameter of thick line silk 4 is 0.3mm, and the diameter of fine rule silk is 0.2mm.
In the present embodiment, the number of times that thick line silk 4 and fine rule silk 5 are walked around on each heel teeth 101 is once, the number of times that fine rule silk 5 is walked around on each heel teeth 101 is 3 times.
As shown in figures 7 and 9, thick line silk 4 is wound around between wire-hanging hook 201 and heel teeth 101, thick line silk 4 on each heel teeth 101 around once afterwards namely on wire-hanging hook 201 around once, next time around another contiguous heel teeth 101, around another wire-hanging hook 201 of 3 rear steering vicinities on each wire-hanging hook 201.According to this canoe, adjacent thick line silk 4 is interlaced.When whole rotating disk is all after complete, by the end of a thread of thick line silk 4 and line tail temporary fixed on wire-hanging hook 201, then with laser-beam welding machine or glue, the end of a thread and line tail to be permanently fixed.
As shown in Figure 8, the winding first with thick line silk 4 is the same, and fine rule silk 5 is wound around between wire-hanging hook 202 and heel teeth 101, fine rule silk 5 on each heel teeth 101 after once, namely on wire-hanging hook 202 around once.Next time around another contiguous heel teeth 101, but wire-hanging hook 202 around invariant position, each wire-hanging hook 201 just turns to another contiguous wire-hanging hook 201 after 3 times.When whole rotating disk is all around once complete, start in a manner described to be wound around second time, but fine rule silk 5 head around heel teeth 101 clockwise direction before miss 5 heel teeths 101, and wire-hanging hook 201 is still wound around by former order.When whole rotating disk is all around complete second time, when starting to be wound around the 3rd time, fine rule silk 5 head around heel teeth 101 miss 5 heel teeths 101 before clockwise direction again, and wire-hanging hook 201 is still wound around by former order.According to this canoe, adjacent fine rule silk 5 is interlaced.When whole rotating disk is all after complete, by the end of a thread of fine rule silk 5 and line tail temporary fixed on wire-hanging hook 202, then with laser-beam welding machine or glue, the end of a thread and line tail to be permanently fixed.
Because wire-hanging hook 201 is not identical from the distance of center of turntable with wire-hanging hook 202 from the distance of center of turntable, so the angle between fine rule silk 5 is different from the angle between thick line silk 5.
Fan blade 3 is uniform along the circumference of rotating disk, and fan blade 3 is 20-35 with the angle α of rotating disk principal plane.
Thick line silk 4 and fine rule silk 5 can be wire or carbon fiber wire, and there is Teflon sprayed coating on surface or through electrophoretic surface process.
The rotary sieve of the present embodiment can be used for the ventilating fan of smoke exhaust ventilator, when the fan motor that rotary sieve is arranged on smoke exhaust ventilator rotates time, upper screen and lower screen form the different careful filter screen of two density, while exhausting, by the particle capture in air on the net, the particulate captured under the influence of centrifugal force gets rid of baffle plate towards periphery, and then particulate falls under gravity into dust-collecting box, and the air of filtering is discharged along the axis of dish type fan.
The structure of the embodiment of the present invention 2 rotary sieve as shown in Figure 10 and Figure 11, only be with the difference of embodiment 1, also comprise the hook cover 6 and 7 of annular, after levels filter screen is all carried out, wire-hanging hook 201 and wire-hanging hook 202 overlap and links up with the bonding of cover 6 and 7 blend compounds, can reinforce levels filter screen further, reduce rotational resistance and the noise of dish type fan, be convenient to the scrubbing of wire-hanging hook site anteseptic.
Above two embodiments of the present invention are described, but under the prerequisite not deviating from the spirit and scope of the present invention, the present invention obviously can also have the form of many changes and change, such as the filter screen number of plies can be increased, or whole disk body is split into some blade shapes etc.
