Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an inclined fluid ultraviolet sterilizer.
More specifically, the present invention relates to an improvement of a device having an inclined fluid plate, which is used for sterilizing fluids such as waste water, water-soluble cutting oil, and fluid foods.

[Conventional technology]

As is well known, ultraviolet germicidal lamps have long been used as a means of sterilizing bacteria in fluids. What is required of these devices is to improve the sterilization effect even with fluids with low ultraviolet transmission efficiency by making the fluid to be sterilized more diffused and in a thin layer, and to make the device small and compact. etc. In this regard, the conventional technology, as shown in Japanese Utility Model Publication No. 35-22597, has an inclined plate and an ultraviolet lamp arranged corresponding to the inclined plate. A device has been proposed in which the fluid is irradiated with ultraviolet rays during the process of flowing the fluid down, and this is a technology that satisfies the above requirements.

[Problem that the invention attempts to solve]

The above-mentioned conventional technology is superior, and the present invention relates to this improvement, but since this type of technology allows fluid to flow down on an inclined plate by the action of gravity, It is also true that there are the following problems. That is, the fluid to be sterilized is supplied from the upper part of the inclined plate, that is, it is made to flow down from the upper storage tank onto the inclined plate. However, in the prior art, an outlet is drilled in the lower part of this storage tank, and the fluid is discharged from the upper part of the inclined plate. The water is allowed to flow out onto the inclined plate. Therefore, near the upper part of the first inclined plate, the fluid partially flows down the first inclined plate as it is to the local part of the upper part, more specifically, to the local part corresponding to the outlet of the storage tank.
The problem disappears as you go down the first and second inclined plates, but around the first inclined plate, the UV irradiation is unevenly distributed on the inclined plates, so it is difficult to irradiate each part of the fluid on average. A difficult problem arises.

Therefore, the object of the present invention is to provide a device having a fluid storage tank integrated at the upper end of the inclined plate, so that the fluid flowing out from the storage tank can be equally distributed to each part of the upper part of the inclined plate. The purpose is to make it possible to make each part of the flowing fluid into a uniformly thin tank. Thereby, each part of the fluid can be uniformly and efficiently irradiated with ultraviolet rays.

[Means for solving the problems] In order to achieve the above object, the present invention has the following technical means. That is, to explain this using the reference numerals in the attached drawings corresponding to the embodiments, the present invention has an inclined plate 3 and an ultraviolet lamp 5 disposed corresponding to the inclined plate 3, In the device that irradiates the fluid with ultraviolet rays during the process of flowing the fluid down, a storage tank 7 is connected to the upper end of the inclined plate 3, and a triangular shape or the like is provided at the boundary between the storage tank and the upper end of the inclined plate. This is an inclined fluid ultraviolet sterilizer characterized by having a weir 3 having a plurality of notches at equal intervals.

[Effect]

With the above configuration, the fluid to be sterilized that has entered the storage tank 7 flows out uniformly from the triangular cutouts formed at equal intervals in the weir 3 and flows onto the inclined plate. Therefore, even in the upper part of the inclined plate, a uniform flow occurs in each part, which means that each part of the fluid becomes a uniform thin tank. Therefore, the bactericidal effect of UV lamps is average,
Overall sterilization efficiency improves.

〔Example〕

Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Waste water, water-soluble cutting oil, and fluid food are first fed through the injection pipe 1 and stored in the storage tank 7. This storage tank 7
An inclined plate 4 is connected to the inclined plate 4, and the fluid flowing down the inclined plate 4 is sterilized by germicidal radiation emitted from an ultraviolet germicidal lamp 5 installed on the upper part of the inclined plate 4, and is then passed through a discharge storage tank 8. The structure is such that it is discharged from the discharge pipe 6.

A manifold pipe can be connected to the injection pipe 1 in the storage tank 7, and a rectifying plate can also be installed.

In addition, the sterilizing effect can be increased by using a mirror or mirror-finished stainless steel on the inner surface of the package 2, or by applying reflective paint.

In such a device, the present invention is provided with a weir 3 having a plurality of triangular cutouts at equal intervals at the boundary between the storage tank 7 and the inclined plate 3.

With this configuration, the fluid to be sterilized that has entered the storage tank 7 flows out uniformly from the triangular cutouts formed at equal intervals in the weir 3 and flows onto the inclined plate. Therefore, even in the upper part of the inclined plate, a uniform flow occurs in each part, which means that each part of the fluid becomes a uniform thin tank. Therefore, the sterilization effect of the ultraviolet lamp is averaged, and the total sterilization efficiency is improved.

〔effect〕

As described in detail above, according to this invention, in a device of the type in which storage tanks are connected on the upper part of an inclined plate; Even in the upper part of the tank, the tank for each part of the fluid can be made uniformly thin, and the irradiation of the ultraviolet lamp to each part of the fluid can be made uniform.
