Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a water treatment device used in sewers and the like.
[0002]
[Prior art]
Conventionally, chlorine-based disinfectants such as sodium hypochlorite are generally used for disinfecting secondary treated water, tertiary treated water or factory effluent at sewage treatment plants.
In recent years, an ultraviolet lamp housed in a jacket is used for sewage treatment or sterilization of factory wastewater, etc., and the treated water is irradiated with ultraviolet rays to be sterilized.
[0003]
[Problems to be solved by the invention]
However, when chlorine-based disinfectants such as sodium hypochlorite are used, harmful substances such as trihalomethane may be generated as a by-product, which may adversely affect the destination ecosystem.
Further, according to the structure using the ultraviolet lamp housed in the jacket, iron, manganese, silicon, aluminum or the like adheres to the jacket and the transmittance of ultraviolet rays is lowered. Therefore, it is necessary to clean the jacket at a constant cycle.
By the way, every time the jacket is cleaned, removing the jacket from the water treatment device and cleaning it requires a lot of work, so the jacket is attached to the water treatment device and the brush is moved back and forth on the jacket surface to remove dirt. Has been proposed. However, according to the structure in which the brush is moved back and forth on the surface of the jacket, there is a drawback that the cleaning effect is small and the deposit remains on the surface of the jacket.
[0004]
The present invention was invented in view of the above points, secondary pollution does not occur, iron, manganese, silicon, aluminum, etc. attached to the surface of the jacket can be effectively cleaned, An object of the present invention is to provide a water treatment apparatus capable of increasing the transmittance of ultraviolet rays from a jacket and performing water treatment effectively with ultraviolet rays.
[0005]
[Means for Solving the Problems]
The present invention described in claim 1 has the following configuration in order to solve the above-described problem.
That is, the present invention relates to a water treatment apparatus in which an ultraviolet lamp is housed in a light-transmitting tubular jacket and at least one jacket is supported on a support.
The annular body is movably supported by the jacket, and a brush is provided on the entire inner surface of the annular body.
Furthermore, a cover body having a central hole is detachably provided on at least one side surface of the annular body so that the tip of the brush projects slightly inward, and the outer surface of the jacket is cleaned with the tip of the brush. It is configured.
According to the water treatment device having the same structure, the jacket can be effectively cleaned with the brush, and the lid is arranged on at least one side surface of the annular body. Few.
[0006]
According to a second aspect of the present invention, the brush according to the first aspect is made of metal, and the brush protrudes 5 mm to 8 mm with respect to the central hole of the lid.
When the jacket is washed, the tip of the brush does not sag, and the jacket can be reliably cleaned.
[0007]
According to a third aspect of the present invention, in the first or second aspect, a plurality of radial protrusions are formed on the outer surface of the lid body detachably provided on the annular body.
And when moving a brush back and forth on the surface of a jacket, it is comprised so that an annular body may rotate by receiving the flow of water, and the cleaning effect of a jacket is heightened.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The water treatment apparatus of the present invention will be described below with reference to FIGS. In the figure, reference numeral 1 denotes a water treatment apparatus main body, which is configured in a box shape, and is installed, for example, in a part of a secondary drainage or tertiary drainage channel of a factory. Reference numeral 2 denotes a jacket disposed inside the water treatment apparatus main body 1 and is made of quartz glass. Further, as shown in FIGS. 1 and 2, the jacket 2 is configured by combining, for example, four jackets as a set. Further, the water treatment apparatus main body 1 is constructed by mounting, for example, six sets of four jackets as shown in FIG. Each jacket 2 is configured with an ultraviolet lamp attached. For example, a 65 watt low-pressure mercury lamp is used as the ultraviolet lamp. The interval between the jackets arranged in combination of the four is configured to be, for example, about 80 mm.
[0009]
Reference numeral 4 denotes a support for supporting the jacket 2 and is composed of vertical legs 5 and 6 positioned at both ends and a horizontal piece 7 connecting the vertical legs 5 and 6 at the upper ends. The horizontal piece 7 has a guide hole 8. A jacket support tube 9 is formed by supporting both ends of the jacket 2 and the ultraviolet lamp in a water-sealed state, and 10 is a pipe covering a lead wire connected to both ends of the ultraviolet lamp. Reference numeral 11 denotes a guide bar which is arranged below the horizontal piece 7 of the support 4 in parallel with the horizontal piece.
[0010]
Reference numeral 20 denotes a moving body that moves laterally along the guide rod 11, and 21 denotes an engaging body provided at the upper end of the moving body 20, which has an engaging recess 22. A driving shaft (not shown) that moves back and forth is engaged with the engaging recess 22 by the rotation of the motor. Reference numeral 23 denotes a frame-shaped brush support provided at the lower end of the movable body 20, which has a vertical groove 24 in the corresponding support.
Reference numeral 25 denotes an annular body that moves along the jacket. A part of the outer periphery protrudes from the longitudinal groove 24 of the brush support 23 and is fitted into the jacket 2 to move back and forth along the jacket. A brush 26 is provided on the entire inner surface of the annular body 25 and is made of, for example, stainless steel. The inner end of the brush has a circular hole 27 slightly smaller than the outer diameter of the jacket 2. Reference numeral 28 denotes an annular lid which is detachably disposed on at least one side surface of the annular body 25, and has a central hole 29 so that the tip of the brush projects slightly inward. The lid 28 is made of, for example, fluorine resin, silicon resin, or stainless steel. Further, the lid 28 is supported on the annular body 25 with, for example, a screw, is not deteriorated by ultraviolet rays, and is not easily soiled.
[0011]
The brush made of metal protrudes inward by about 5 mm to 8 mm from the central hole 29 of the lid 28. When the brush is less than 5 mm with respect to the central hole 29 of the lid body 28, the inside of the lid body 28 comes into contact with the surface of the jacket 2, and the movement of the annular body 25 is hindered.
On the other hand, if it exceeds 8 mm, the brush will become heavier and the cleaning effect will be reduced. According to the result of the experiment, if the brush protrudes inward by about 5 mm to 8 mm with respect to the central hole 29 of the lid 28, the cleaning effect is great.
[0012]
In the invention described in claim 3, the lid body 28 detachably provided on the annular body 25 has a flat outer surface, and a plurality of radial protrusions 30 are formed on the outer surface of the lid body 28. It is. For example, four radial protrusions 30 are formed at the same interval. The height of the protrusion 30 is about 10 mm.
According to the structure, when the brush is moved back and forth on the surface of the jacket, the brush rotates, and the cleaning effect of the jacket is enhanced.
[0013]
【The invention's effect】
According to the first and second aspects of the present invention, the outer surface of the jacket can be brushed with an appropriate pressure, and there is a special effect that the cleaning effect of the jacket is enhanced.
[0014]
According to the third aspect of the present invention, since the brush moves back and forth on the surface of the jacket while rotating, there is a special effect that the cleaning effect of the jacket is further enhanced.
