Abstract

PURPOSE:To facilitate the assembling and diassembling of a sterilizer by forming a flange at the end part of a casing facing at least one of the end members, and connecting said member detachably to the flange through an annular clamping member. CONSTITUTION:In an ultraviolet sterilizer for flowing water, an ultraviolet lamp 16 is lit, and the water is passed through an annular space between a casing 10 and a quartz tube 15 from a water inlet 12. The water snakes forward through the arrangement of baffle plates 20, and flows out from a water outlet 11. Since ultraviolet rays irradiated from the ultraviolet lamp 16 are transmitted through the quartz tube 15, said flowing water is sterilized by the ultraviolet rays. The ultraviolet lamp 16 can be taken out by removing a set-screw 26 and removing a clamping plate 27 from a cap nut 23. The quartz tube 15 can be released by removing the cap nut 23 from a screw pipe 22b of a cap body 22.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides support between two end members that close both ends of a quartz tube disposed in a cylindrical casing and a rod-shaped ultraviolet lamp r1 casing housed therein. This invention relates to an ultraviolet spider sterilizer for running water, in which an ultraviolet lamp is turned on, water is poured over the casing and quartz 'el (1) lII+1, and the running water is sterilized with ultraviolet rays.

In such conventional UV sterilizers for running water, at least one end member is connected to the opposite end of the casing by a bolt/nut assembly.

Therefore, assembly and disassembly are difficult and require tools, and maintenance such as cleaning is not easy. These drawbacks are fatal to ultraviolet sterilizers for running water, which must be kept clean by washing.

Therefore, the main purpose of this invention is to provide an ultraviolet sterilizer for running water that eliminates the above-mentioned conventional drawbacks.

In order to achieve this object, the ultraviolet sterilizer for running water according to the present invention has a flange formed at the end of the casing facing at least one end member, and a flange is formed in the end of the casing facing the at least one end member. According to this special %sQk, which is characterized in that the sterilizers are removably connected by an annular clamp member, the connection by the annular clamp member and its removal can be easily accomplished manually and without tools, so that the assembly and the sterilizer are easy. It is easy to disassemble and therefore easy to maintain.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The implementation of the present invention will be described in detail below with reference to the drawings.

Figures 1 and 2 show the ultraviolet sterilizer for running water of this invention.
In the figures (for clarity, the arrangement of components is drawn slightly different between these figures), a cylindrical casing /Q made of stainless steel with electropolished inner and outer surfaces is arranged horizontally. /
The upper part near the end and the lower part near the end have socket-shaped water outlet // and water inlet respectively. The casing 10 also has a viewing window 3 in the center using a polycarbonate resin plate (which blocks external rays but allows visible rays to pass through), and also has mounting legs ≠.

Prepare the lhiro in one suitable place.

Inside the casing 10, a rather long cylindrical quartz tube/j is arranged in a substantially semicircular shape, and the quartz tube/! Inside is a rod-shaped ultraviolet lamp /2 with sockets at both ends) /7.
/7 is installed. In the annular space between the casing 10 and the quartz tube /j, there are two support rods l♂ extending in the axial direction.

/, r (only one is shown in Figure 2, and only the positions of the other seven are shown) and several notched disk-shaped baffles fixed to these support rods /ri, /ri, A baffle plate assembly 20 consisting of... is accommodated. This baffle plate assembly,
20 serves to guide the water flowing in from the water inlet/2 along a meandering path within the annular space and then to reach the water outlet//.

Both ends of the quartz tube lj are closed by one end member J/A, 2/H (end member J/A and island j/B).
are shown in FIG. 1 as being on the left and on the right, respectively, and in FIG. 2 as being on the right and on the left, respectively)3. End members Co/A and Co/B
Each one is a quartz tube/! Annular disc closing /4 of 22a
and an externally threaded short pipe protruding outward from its inner diameter - λb and t
It has a fixed shape of 1m body -λ. The external threaded tube λλb of the cap f$2-2 is a quartz tube/! The cap nut +23 is screwed onto the externally threaded pipe 2λb of the cap body 22 so as to sandwich the O-ring, 2≠, and the O-ring retainer 2j. Tighten the cap nut 23 and the quartz tube/! is fixed fluid-tightly by an O-ring cog.

Fukuro Naratoko 3 is a quartz tube! It has a central opening from which an ultraviolet lamp /6 and a socket /7 housed in can be taken out, and this central opening is closed by a stop plate λ7 which is tightened to a cap nut λ3 by a set screw JA, λ6. The stop plate 27 has a through hole through which the conductor 2g to the socket/7 passes.

A flange λ is formed on the end member 4iflI of the casing 10 facing the annular disk of the cap body 22 of 2/A.
The annular disc 2.2a of λ is removably connected to the flange λ by an annular clamping member 30. At the time of this connection, an annular disk and a flange are used to make the connection liquid-tight.
'Patsukin 31 is inserted between the gaps. The annular clamp member 3Q has two substantially semicircular tightening pieces 36, 36 with a shield shape that surround both the peripheral edge of the flange λ and the peripheral edge of the annular plate λ2a of the cap body 2λ from the outside. , both thin strips 36.3t are connected to each other so as to be openable and closable at the ends thereof, as indicated by the symbol 3λ. In addition to the two tightening pieces 36.3t, the tool 33 is used to press them together in a screw type manner.

With such an annular clamp member 30, the end member co/A
It is clear that it can be installed very easily on the flange rotor and that its removal can also be accomplished very easily.

The annular disc λλa of the cap body 12 of the end member 2/B is fixed to the casing IO by bath welding or the like. A drain hole 3≠ is formed in these two annular discs, and this is normally a removable plug J! Closed by. In addition, as an alternative, the four-part member 7B may also be removably attached to the casing 10 with an annular clamp member 30 in the same manner as the four-member member 27A.

In the running water garden killing device configured as described above, the ultraviolet lamp 6 is turned on and the casing 10 and quartz tube l! If water is allowed to flow from the water inlet into the annular space between the quartz tubes, the water will meander through the annular space depending on the arrangement of the baffle plate assembly, flow out from the water outlet, and then flow through the quartz tube. Since the ultraviolet rays emitted from the extra-system lamp 16 pass through, the aforementioned running water is sterilized by the ultraviolet rays.

In the above-mentioned running water external radiation sterilizer, the set screw 26f:
By removing the retaining plate 27f from the cap nut 23, the ultraviolet lamp/A can be taken out. When the cap nut 23 is removed from the external threaded pipe 2λb of the cap body 2λ, the quartz tube 16 can be removed. Further, by opening the annular flange member 30 and removing it from the end member λ/Ai casing IO, the baffle plate assembly 20
In this manner, the baffle plate assembly 20, the casing io, etc. can be cleaned very easily. Incorporation of each component cost element is also the reverse operation F as described above.
'F- can easily be achieved.

In this way, such a running water system external membrane device can not only eliminate the conventional drawbacks mentioned above, but also ensure that the inner and outer surfaces of the casing 10 (in fact, other surfaces that come into contact with running water) are #! Since it is L-polished, there are fewer micropores than the conventional puff finish, making it easier to clean and maintain. It is desirable to use a UV lamp for both vertical and horizontal use, and as mentioned above, the water inlet 12 and the water outlet/
If the sterilizer is placed near the end of the casing io, the sterilizer can be used without any problems whether it is placed horizontally or vertically since there is virtually no air pocket.
