Abstract

PURPOSE:To effectively perform washing by stirring the liquid for washing the object to be washed received in a container by the liquid injected from a jet orifice. CONSTITUTION:When a pump 10 is operated, the pressure of the water 2 from a discharge port 9 is raised to be sent into a piercing hole 18. When a compressor 15 is operated, oxygen 7 in an oxygen source 16 is compressed and the pressure of oxygen 7 is set so as to be higher than that of the water 2. The water is send under pressure by the pump 10 to be injected from a jet orifice 6 and, therefore, an object to be washed can be forcibly moved. The bubbles of oxygen 7 are mixed with the water 2 through the pores of a filter 19 by a mixer 8 to dissolve oxygen 7 in the water 2 and, therefore, the contact of the object to be washed in the water 2 with oxygen 7 can be increased and the washing effect of the object to be washed is enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning device for cleaning an object to be cleaned in a cleaning liquid.

[Prior Art J] A conventional cleaning device cleans the object to be cleaned in the cleaning liquid by ejecting a large number of bubbles into the cleaning liquid filled in the cleaning tank.

[Problem to be Solved by the Invention 1] The conventional cleaning device U jets air bubbles into the cleaning liquid filled in the cleaning tank, and agitates the cleaning liquid using the force generated by the movement of the jetted air bubbles. There is a
Since it floats on the surface of the cleaning solution, cleaning cannot be performed efficiently. Furthermore, if the cleaning liquid is stirred only by the force generated by the movement of the ejected bubbles, the floating object cannot be submerged into the cleaning liquid again.

An object of the present invention is to provide a cleaning device that can effectively clean items to be cleaned.

[Means for Solving the Problems] According to the present invention, the object is to provide a container for containing a liquid for cleaning an object to be cleaned, and a container provided in the container for spouting the liquid into the container. This is achieved by a cleaning device comprising a spout, and a mixer connected to the spout to mix bubbles of gas for cleaning the object into the liquid to be spouted and dissolve the gas. Ru.

[Operation 1 According to the present invention, since the liquid for cleaning the object to be cleaned contained in the container is stirred by the liquid jetted from the spout, the object to be cleaned contained in the liquid in the container is agitated. The cleaning effect of the object to be cleaned is improved because the gas bubbles for cleaning the object to be cleaned can be mixed and dissolved into the liquid spouted from the spout by the mixing device. let 19
Ru.

As the cleaning liquid according to the present invention, various organic solvents such as perchloroethylene used in laundry, water, or a cleaning agent may be used as necessary.

As the cleaning gas according to the present invention, a gas suitable for the purpose of cleaning can be appropriately selected and used, and air, preferably oxygen, may be used.

The ceramic filter, which is a preferable feature of the mixer according to the present invention, preferably has a pore diameter of 0.1 to 3 microns. Thereby, the bubbles of the cleaning gas mixed into the cleaning liquid can be made smaller, and the cleaning effect can be increased. Further, the filter may be a hexagonal columnar filter with 19 through holes, or a cylindrical filter with one through hole.

[Specific Examples] Hereinafter, the present invention will be described in detail using preferred specific examples shown in the drawings.

In the figure, a cleaning tank 1 contains cleaning water 2 kept at a suitable low temperature, and an object to be cleaned (not shown) is placed in the water 2. The tank 1 is a stainless steel container having an elliptical horizontal cross section with a long axis 3 of 700 rna and a short axis 4 of 400 m, and a depth of 800 rna. The tank 1 may have a perfectly circular horizontal cross section. 500 from the top of tank 1
11Il! At positions I and facing each other with respect to the central axis of the tank 1, the tank 1 is provided with spout ports 6 extending along the inner surface of the tank 1 in a direction parallel to the longitudinal axis 3.

A mixer 8, which will be described later, is connected to the spout 6 to mix oxygen 7 into the water 2 for cleaning the object to be washed. A discharge port 9 is provided at the bottom of the tank 1 for discharging the water 2 in the tank 1. A pump 10 for circulating water 2 is provided at an appropriate location, and an inlet 11 of the pump 10 is connected to an outlet 9, and two outlet ports 1 of the pump 10 are connected to each other.
2 are each connected to an inlet 13 for water 2 of the mixer 8. The discharge pressure of the pump 10 is 1 to tokof10+! It is. IC compression 1f that sends compressed oxygen 7 to mixer 8
i15 is provided at an appropriate location, the suction port of the compressor 15 is connected to an oxygen source 16 that stores oxygen 7, and the discharge port of the compressor 15 is connected to the inlet for oxygen γ of the mixture 68. 1
Connected to 4. The discharge pressure of the compressor 15 is 1 to 15 gf/cd.

The details of the mixer 8 will be explained below.

The mixer 8 includes a cylindrical casing 17 and a casing 17.
It has 19 through holes 18 along the longitudinal axis direction, and a hexagonal columnar ceramic filter 19 housed coaxially in the casing 17 and fixed to one end of the casing 11. and an inlet flange 20 supporting the filter 19 at one end thereof, and the casing 1
an outlet flange 21 fixed to the other end of the filter 19 and supporting the filter 19 at the other end; and an inlet provided on the circumferential side of the casing 17 and communicating with an annular space 22 between the casing 17 and the filter 19. It consists of 14. The flange 20 has an opening 23 in the center so that the through hole 18 is exposed, and the flange 21 similarly has an opening 24.
have.

One side of the filter 19 is 16 mm, and the diameter of the through hole 18 is 4 mm. The ceramic constituting the filter 19 is a Δ1203 sintered body with a pore diameter of 0.61 to 0.3 microns.The operation of a specific example of the present invention will be described below.

When the tank 1 is filled with water 2 and the pump 10 is operated, the water 2 from the outlet 9 is pressurized to 1 to 10 Kgf/cd and is sent to the through hole 18 through the opening 23 of the mixer 8. When compression 1i15 is activated, I! Oxygen 7 in source 16 is compressed to 1-15 KCIf/ci and sent to annular space 22 via inlet 14 of mixer 8 . Here m element 7
The pressure of water 2 is set higher than that of water 2.

Oxygen 7 is mixed into the water 2 flowing through the through hole 18 in the form of bubbles through the filter 19 and is dissolved therein. The water 2 sent out from the opening 24 of the mixer 8 is jetted into the tank 1 through the spout 6 . As a result, the water 2 in the tank 1 is swirled and agitated as shown by the arrow 25 within the tank 1, and the objects to be cleaned that have been placed in the water 2 in the tank 1 are moved and cleaned.

Since the water 2 is pumped by the pump 10 and ejected from the ejection port 6, it is preferable that the speed of ejection of the water 2 from the ejection roller 1 to forcibly move the object to be cleaned is as high as possible.

Since the mixer 8 mixes bubbles of oxygen 7 into the water 2 through the pores of the filter 19 and dissolves the oxygen 7, the object to be cleaned in the water 2 and 1! The contact with the element 7 can be increased, and the cleaning effect of the object to be cleaned can be improved.

In FIG. 5, a solid line 26 shows the amount of dissolved oxygen in the water 2 when the mixer 8 is used to blow out only oxygen without circulating the water 2, and a solid line 27 shows the amount of dissolved oxygen in the case of this specific example. Indicate quantity. According to FIG. 5, it can be seen that in this specific example, the dissolved oxygen value in the water 2 can be almost saturated in about one hour.

[Effects of the present invention] According to the present invention, since the liquid for cleaning the object to be cleaned contained in the container is stirred by the liquid jetted from the spout, the liquid contained in the container is The object to be cleaned can be forcibly moved, and gas bubbles for cleaning the object to be cleaned can be mixed and dissolved by the mixer into the liquid spouted from the spout, which improves the cleaning effect of the object to be cleaned. can be directed.
