TECHNICAL FIELD OF THE INVENTION
The present invention relates to a discharge tube connection device and a connection method used in an ozone generation device.
[0002]
[Prior art]
In an ozone generator, for example, a plurality of discharge tubes each having a high-voltage electrode provided on the inner peripheral surface of a cylindrical dielectric are arranged in parallel, and a high voltage is applied to the high-voltage electrodes of each of the discharge tubes to generate ozone. A large capacity ozone generator of a so-called silent discharge type is used.
[0003]
Many discharge tubes as shown in FIG. 3 are used in this silent discharge type ozone generator. In FIG. 3, reference numeral 1 denotes a discharge tube formed of a glass tube (dielectric tube) having one end closed, and a high-voltage electrode 2 is formed on the inner periphery thereof by coating a metal such as Al or SUS. A metal brush 3 and a fuse 4 that are in contact with the high-voltage electrode 2 are arranged on the inner circumference of the discharge tube 1, and a male thread 5 is engraved at the tip of the fuse 4.
[0004]
In the discharge tube configured as shown in FIG. 3, the high-voltage electrode must be connected to a high-voltage insulator (not shown). In this case, as shown in FIG. 4, a metal plate 6 is attached to the external thread portion 5 of the discharge tube 1 with a screw 7, and the discharge tubes 1 are connected to each other. The discharge tube 1 and a high-voltage insulator (not shown) are also connected in the same manner as in FIG.
[0005]
[Problems to be solved by the invention]
A large capacity ozone generator uses several tens to one hundred and several tens of discharge tubes. In order for all of the discharge tubes to be electrically connected, at least two metal plates 6 must be protruded from one discharge tube, and the number of metal plates must be equal to or greater than the number of discharge tubes. And the connection work was difficult. Also, it is uncertain as to whether or not all the discharge tubes are electrically connected as the number of discharge tubes increases, and the possibility that there are discharge tubes that are not connected increases.
[0006]
The present invention has been made in view of the above points, and an object of the present invention is to provide a discharge tube connection device and a discharge tube connection method for an ozone generator that can reliably connect a large number of discharge tubes by a simple connection operation. It is in.

At the same time, the other end of the metal plate is fixed, a female thread portion is carved, and a plurality of discharge tubes are arranged around the one discharge tube so as to form a plurality of concentric circles on its outer periphery. The other end of the center discharge tube fuse is screwed to the hole of the metal plate of the discharge tube and the female screw of the metal plate of the discharge tube adjacent to the discharge tube on the same circle. The electrical connection between the other end of the fuse of each one discharge tube on the concentric circle and the high voltage insulator. It is set to.
[0008]
(3) One discharge tube can be easily connected to a plurality of discharge tubes only by providing one metal plate. Since one end of the metal plate is fixed to the fuse in advance, the discharge tube can be reliably connected by a simple operation of simply screwing the hole and the female thread.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
The discharge tube connecting device of the present invention is configured as shown in FIG. FIG. 1 shows only a part inserted into the discharge tube 11. In FIG. 1, one end of a metal plate 16 is fixed in advance to the tip of a fuse 14 inserted into the inner peripheral portion of the discharge tube by welding. Further, a female screw 17 is engraved on the welded portion of the metal plate 16 and inside the tip of the fuse 14. An elongated hole 18 is provided at the other end of the metal plate 16. The distance between the female screw 17 and the elongated hole 18 is equal to the distance between the centers of adjacent discharge tubes.
[0010]
Next, a method of connecting the discharge tubes configured as shown in FIG. 1 will be described with reference to FIG. First, a plurality of discharge tubes 11b to 11n are arranged so as to form a plurality of concentric circles around the outer periphery of one discharge tube 11a. The female screw 17 of the adjacent discharge tube on the same circle is screwed and connected. Next, between the other end of the fuse of the central discharge tube 11a and the high-voltage insulator 21 provided on the outer peripheral portions of the plurality of discharge tubes, a conventional concentric circle is connected so as to bridge all concentric circles. Connection is made by a similar metal plate 6. The method of connecting the concentric circle and all the concentric circles and the high-voltage insulator 21 to the central discharge tube 11a is not limited to the metal plate 6, but may be a conductive wire or the like.
[0011]
With such a connection method, a large number of discharge tubes can be easily connected. Since one end of the metal plate 16 is fixed to the fuse 14 in advance, the discharge tube can be reliably connected by a simple operation of simply screwing the long hole and the female screw.
[0012]
【Example】
In addition, when all the discharge tubes are not on concentric circles, that is, when the number of the discharge tubes arranged on the outer periphery does not form a concentric circle as shown in FIG. For example, the long hole 18 of the metal plate 16x and the female screw 17 of the discharge tube on the adjacent concentric circle are screwed.
[0013]
【The invention's effect】
As described above, according to the discharge tube connecting device and the discharge tube connecting method of the present invention, the following excellent effects can be obtained.
[0014]
(1) Since one end of the metal plate is fixed to the fuse in advance, the connection of the discharge tube can be reliably performed by a simple operation of simply screwing the hole and the female thread. This greatly simplifies the operation when connecting a large number of tens to hundreds of tens of discharge tubes.
[0015]
(2) A large number of discharge tubes can be easily connected, and the connection can be confirmed more reliably.
[0016]
(3) Only one metal plate for connecting the discharge tubes is required for each discharge tube, which is excellent in economy.
