Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention proposes a precision machine that uses a lightweight levitation material and that is easy to operate and maintain.

[Conventional technology]

2. Description of the Related Art Conventionally, the use of floating materials such as pond water is well known. An example of this is No. Sho 62-132703. As shown in FIG. 1, the liquid that has risen in the levitation material layer and has passed through it is provided at the upper part of the excess chamber through the water collection nozzle. It is collected in a liquid reservoir and overflowed from this.

[Problems to be solved by the invention]

However, although the above-mentioned conventional ones use small particles of expanded styrol as the material, there is a limit to the particle size. That is, it is difficult to manufacture the foamed styrol to have a particle size of 2 m / m or less. Therefore, when a material having a particle size of about 2 m / m is used, there is a limit to the size of impurities that can be captured. However, with this type of machine, which uses a levitation material, the S and S of the liquid are 10 to 40 μm, and it is impossible to make a precise flow.
In this way, for liquids with large particle diameters, if this machine is used for over pond water or over cooling water for the cooling tower, it will be irradiated with ultraviolet rays to sterilize the water-bloom etc. generated in the circulation system. Even so, there is a problem that the above-mentioned S and S act as a barrier and cannot be sterilized.

[Means for solving problems]

Therefore, the present invention is to solve the above-mentioned problems, and the structure thereof is the above-mentioned in the over-flow type machine having the excess chamber in which the floating material is housed and the liquid reservoir provided in the upper chamber. A large number of precision excess cylinders are detachably installed in the liquid reservoir, and these excess cylinders are connected to the filtrate outlet pipe, and a drain outlet is provided at the bottom of the liquid reservoir and an undiluted liquid supply port at the bottom of the excess chamber. Is provided for easy precision cleaning and cleaning.

[Action]

Since the machine according to the present invention is configured as described above, the liquid passed by the floating material can be passed by the precision overuse material in the liquid reservoir. That is, it is possible to obtain a clean liquid by removing the impurities that cannot be removed by the conventional floating material by re-passing the liquid in the floating material. And, this second-stage device is
Since it is integrated with the surfacing device using the levitation material, it is possible to perform the same operation as one unit, such as the supply of the undiluted solution for the surplus. Also, when the material is clogged, the part that uses the floating material can be backwashed as before, and the precision excess part can be replaced or removed because the material is removable. It can be done easily.

〔Example〕

In FIG. 1, reference numeral 1 is an over tank, 2 is an over chamber, 3 is an over chamber 2 filled levitation material, 4 is a water collecting nozzle, 5 is a liquid reservoir, and 6 is a precision overuse provided in the liquid reservoir 5. It is an overcylinder, and the one shown in FIG. 1 is made of a ceramic having fine holes in its peripheral portion as shown in FIG. Reference numeral 7 is a liquid extraction pipe, 8 is a drain outlet of the liquid reservoir 5,
Reference numeral 9 represents a supply port for the stock solution.

In the precision passing machine configured as described above, the undiluted solution (raw water) to be passed is supplied from the supply port 9 to the over chamber 2, and the levitation material 3 is pushed up by this undiluted solution to form a consolidated overlayer. In the undiluted solution that has passed through the layer, the impurities are captured by this overlayer, and the solution rises in the liquid reservoir 5 through the water collecting nozzle 4. Since the liquid that has risen to this liquid reservoir 5 has only passed through the levitation material 3, it is possible to use coarse contaminants (particle size 40 μm).
However, it is further filtered by the excess cylinder 6 in the liquid reservoir 5 and taken out from the take-out pipe 7. The liquid taken out from the take-out pipe 7 contains foreign substances having a particle size of about 10 μm or less.
Next, when the levitation material layer and the over-cylinder 6 are clogged by the above-described operation, washing water is injected from the liquid extraction pipe 7 to backwash the over-cylinder 6 and the levitation material layer, and vice versa. The wash water can be drained from the drain outlet 8 and the supply port 9 to regenerate the material.

[Effect of device]

As is clear from the above description, the precision machine according to the present invention is a combination of the machine using the lightweight levitation material and the precision machine provided in the liquid reservoir of the machine.
When the floating material layer and the excess cylinder are clogged, the material can be regenerated by injecting washing water from the liquid extraction pipe. Since the excess cylinder is detachable, it can be easily replaced or removed and cleaned.
