[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to a processed product to which oil is attached,
For example, the present invention relates to a hermetic water-based cleaning device for cleaning a treated material to which quenching oil is attached.

[0002]

2. Description of the Related Art Conventionally, in order to remove oil from a treated product to which oil has adhered, Freon, triethane and the like have often been used. However, in recent years, water-based cleaning has been reviewed due to problems such as environmental destruction. . By the way, an alkaline liquid is mainly used as a cleaning medium for this aqueous cleaning, and as a cleaning method, a method in which the alkaline liquid is lightly stirred by bubbling, a pump or an agitator, and the object to be cleaned is immersed therein. A method of showering a cleaning liquid on an object to be cleaned,
And the like. However, in water-based cleaning, oil is mainly removed by a peeling action. However, in any of the above methods, the physical force required for peeling is not sufficient, and a high cleaning rate (oil and fat removal rate) is required.
However, there was a problem that it could not be obtained.

[0003]

According to the present invention, when the object to be cleaned is heated, or when the cleaning liquid is heated to a temperature higher than the conventional temperature (50 to 80 ° C.), the viscosity of the adhered oil decreases, and the releasability is reduced. It has been made by paying attention to the fact that a high cleaning rate can be obtained even with aqueous cleaning.

[0004]

According to the present invention, a closed-type water-based cleaning device is provided with an immersion cleaning tank connected via an opening / closing shutter below a spray cleaning chamber provided with a charging / extracting door. While a circulation fan and a heater for heating are disposed in the spray cleaning chamber, a heater for heating a cleaning liquid is provided in the immersion cleaning tank;
One end is opened below the object to be cleaned, and the other end is provided with a rectifying duct provided with a forward / reverse rotation type agitator, and
A transfer means for transferring an object to be cleaned is provided between the spray cleaning chamber and the immersion cleaning tank.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The closed type aqueous cleaning apparatus A of the present invention generally includes a spray cleaning chamber 1, an immersion cleaning tank 10 provided below the cleaning chamber 1 via an opening / closing shutter 6, and an object S to be cleaned. 1 and a transfer means 7 for transferring between the immersion washing tank 10.

The spray cleaning chamber 1 has a charging / extraction door (not shown), a circulation fan 2 is provided on the ceiling of the chamber, and a baffle 3 is provided in the spray cleaning chamber 1.
A spray device 4 is provided at the upper portion of the baffle 3 for increasing the pressure of a cleaning liquid W in the immersion cleaning tank 10 by a pump P and spraying the cleaning liquid W downward. Further, a heater 5 for heating is arranged on the side of the baffle 3.

The immersion cleaning tank 10 is connected below the spray cleaning chamber 1 via a known opening / closing shutter 6 provided in the spray cleaning chamber 1.
Inside, a cleaning liquid heater 11 and one end of a rectifying duct 15 open upward toward the spray cleaning chamber 1,
Forward / reverse rotation type agitator 13 having stirring blade 14 on the other end side
Is installed. The transfer means 7 is composed of an elevator which is moved up and down by a cylinder 8 provided outside the apparatus A. The object S to be cleaned loaded from a loading / extracting door (not shown) is placed on the transporting means 7 and the spray cleaning chamber 1 and the immersion cleaning tank. 10 and up and down. The spray cleaning chamber 1 and the immersion cleaning tank 10 are integrated in an airtight structure.

The closed type water-based cleaning device A according to the present invention comprises:
For example, since the cleaning object S is placed on the elevator 7 of the spray cleaning chamber 1 from the charging / extraction door, the heater 5 is energized, and the circulation fan 2 is driven. The cleaning object S is, for example, 100 to
Heat to 150 ° C. to soften the oil adhering to the object to be cleaned S,
For example, the washing liquid W at 95 ° C. in the immersion tank 10 is showered from the shower device 4 by the pump P to remove the adhered oil. Thereafter, the elevator 7 is lowered to immerse the object S to be cleaned in the cleaning liquid W, and the agitator 13 is driven to drive the high-temperature cleaning liquid W through the opening 15 a of the rectifying duct 15.
Is discharged at a predetermined flow rate, and the cleaning liquid is vigorously stirred by this discharge force to remove the remaining oil of the object S to be cleaned.

Since the agitator 13 is a reversible type,
Since the direction of the water flow of the cleaning liquid W with respect to the cleaning target S changes from top to bottom and from bottom to top, cleaning unevenness does not occur. During this time, if the object to be cleaned S is a small object, it swings,
The cleaning power can be increased.

As described above, when the oil is separated,
The object S to be cleaned is again spray-cleaned by the elevator 7.
After rinsing the surface with the spray device 4, the circulation fan 2 is driven and dried by convection heating to complete the cleaning process.

The following steps may be performed without performing all of the above steps, depending on the type of the oil adhered and the properties of the object to be cleaned. Spray cleaning → heating → immersion (stirring / oscillation) → spray cleaning → drying Heat → immersion (stirring / oscillation) → spray cleaning → drying immersion → heating → immersion (stirring / oscillation) → spray cleaning → drying and immersion The temperature of the liquid W is not limited to the above.

The opening / closing shutter 6 is closed when the apparatus A is empty, when the circulation fan 2 is driven, and when the object to be cleaned S is in the immersion cleaning tank 10.
Alternatively, heat loss of the cleaning liquid W is suppressed.

[0013]

As is apparent from the above description, according to the present invention, since the heater for cleaning and the circulation fan are provided in the spray cleaning chamber, the object to be cleaned is appropriately heated to increase the viscosity of the adhered oil. And the attached oil can be easily removed by spray cleaning. In the immersion cleaning tank, the high-temperature cleaning liquid is strongly sprayed on the object to be cleaned by the agitator, and the spraying direction is variable, so that the softened adhered oil can be removed without uneven cleaning.
