Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a rotary ozone generator for extracting ozone by applying a high voltage between a rotating electrode and a fixed electrode to generate a discharge between the two electrodes. .

[Conventional technology]

As shown in FIG. 5, the conventional rotary ozone generator is equipped with a Shirotsuko fan 51 on one side of a motor 50 and an ozone generator 52 on the other side, and the air compressed by the Shirotsuko fan 51 is passed through a duct 53 to generate ozone. Casing 5 of generator 52
4 and a rotating cylinder 55, a discharge is caused between a casing 54 which forms a fixed electrode and a rotating cylinder 55 which forms a rotating electrode to generate ozone, and the ozone is taken out from an outlet 56.

[Problem to be solved by the invention]

However, in the conventional rotary ozone generator, the ozone generator 52 and the Shirotsukou fan 51 are separated, which not only increases the size of the device, but also requires the provision of a duct 53 that connects the Shirotsukou fan 51 and the casing 54, which increases the number of parts. There are other problems.

In view of these points, an object of the present invention is to provide a rotary ozone generator that is compact as a whole, has a small number of parts, and has a short motor shaft.

[Means to solve the problem]

Therefore, in the present invention, a motor is provided on a side plate having an air suction port, a conductor shaft of a Sirotskov fan, which also serves as a rotating electrode, is connected to the shaft of this motor via an insulating tube, and an insulating shaft is connected to the side plate so as to surround the Sirotskov fan. A casing having a discharge port made of material is attached, an arc-shaped fixed electrode plate is provided on the cylindrical part of this casing, a high voltage supply section is formed in the center of the casing on the opposite side of the motor, and a high voltage supply section is provided with a high voltage supply section. The contactor is provided so as to be biased into contact with the conductor shaft.

[Effect]

The rotating blades are used as rotating electrodes, the rotating blades are equipped with the function of a fan to compress outside air, and the casing that houses the rotating blades is made to function as a fixed electrode, so the device can be used both as a fan and as an ozone generator. The whole thing becomes more compact.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, the ozone generator M of the present invention has a motor 1. A conductor shaft 4 is connected to the shaft 2 of the motor 1 via an insulating tube 3 made of a foot material or the like. An end plate 6 of a Sirotskov fan 5, which also serves as a rotating electrode, is fixed to the shaft 4.

The Sirotskov fan 5 is housed in a casing 7 made of an insulating material, and a high voltage supply section 7a is provided in the center of the side plate of the casing 7 on the opposite side of the motor 1.
is formed. The high voltage supply section 7a has an opening 8 in which a contactor 10 biased by a spring 9 is housed. The contactor 10 is made of carbon, and its tip is in contact with the end surface of the conductor shaft 4. The spring 9 is connected to the high voltage supply wire 1 by means of a screw 11.
2 are connected.

An air intake port 13a is formed in the side plate 13 of the casing 7 on the motor 1 side.
The air sucked through 3a is compressed and discharged from the outlet 7a of the casing 7, which extends in the connecting direction to the outer periphery of the Sirotskov fan 5. The side plate 13 is made of an insulating material such as fluorine and is fixed to the motor 1 with screws 14, and the outer periphery of the side plate 13 is fixed to the flange 7b of the casing 7 with bolts 15.

As shown in FIG. 2, a conductor housing part 7c is formed in the cylindrical part of the casing 7, and an arc-shaped fixed electrode plate 16 is housed in the conductor housing part 7c. A conductor 16a is covered with an insulating material, and a high voltage supply wire 17 is connected to the conductor 16a.

The Sirotskov fan 5 also forms a conductor, thereby creating a discharge space S between the outer circumferential surface of the Sirotskov fan 5, which forms a discharge body, and the fixed electrode plate 16 provided corresponding thereto.
is formed, and due to the discharge within this discharge space S,
Compressed air sucked in through the air intake port 13a and compressed is changed into ozone, and the generated ozone is taken out through the exhaust port 7a.

As shown in FIG. 3, the conductor storage portion 7c forms mounting recesses 7d into which both ends of the fixed electrode plate 16 are removably mounted.

〔effect〕

As explained above, according to the present invention, a motor is provided on a side plate having an air suction port, a conductive shaft of a Sirotskov fan which also serves as a rotating electrode is connected to the shaft of the motor via an insulating cylinder, and the Sirotskov fan is attached to the side plate. A casing having a discharge port made of insulating material is attached to surround the casing, an arc-shaped fixed electrode plate is provided on the cylindrical part of the casing, and a high voltage supply section is formed in the center of the casing on the opposite side of the motor. Since the contactor is provided in the high voltage supply section so as to urge and abut against the conductor shaft,
Not only can the ozone generator be shortened with just two parts, the motor and the fan, but the entire device is also more compact and has fewer parts.
Moreover, since the motor shaft is also shortened, it is possible to reduce costs.
