BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirring type cleaning apparatus.

[0002]

2. Description of the Related Art Stirring blades are provided on both end walls of a rectangular cleaning tank so as to oppose each other. An object to be cleaned such as a machine component is charged into the cleaning tank and adhered to the object to be cleaned by a high-speed cleaning liquid. Cleaning devices that remove oil and dust are well known. A typical example of this type of cleaning apparatus is disclosed in Japanese Patent Publication No. 55-22155.
Can be cited. In this cleaning device, the flow pattern of the cleaning liquid in the cleaning tank is temporally changed in various forms by automatically changing the rotation direction of a propeller-type stirring blade attached to both end walls of the cleaning tank. In other words, there is an advantage that the surface of the object to be cleaned can be uniformly cleaned without causing a blind spot of the flow of the cleaning liquid in the tank. Furthermore, by selecting and using a cleaning liquid having an appropriate composition, it is used for cleaning oil and dust of many machine parts such as vehicle parts, aircraft parts and industrial machines, and particularly for cleaning and removing lubricating oil of bearings of vehicle bogies. It is effective.

[0003]

However, the conventional stirring type cleaning apparatus described above has the following problems. That is, the oil and dust removed from the surface of the object to be cleaned by the cleaning action are partially sludge-like and suspended in the cleaning liquid, and partly are scum-like and float on the surface of the cleaning liquid. I have. If the cleaning operation is continued as it is, the sludge and scum of the sludge and scum may be removed by any means because the oil and dust removed from the corners may adhere to the object to be cleaned again and reduce the cleaning effect. Material needs to be removed. In this regard, the aforementioned Japanese Patent Publication No. 55-22155
In No. 2, a detachable cartridge is attached to one end wall of the washing tank in the vertical direction, a part of the washing liquid is introduced into the cartridge using the flow in the washing tank, and the above substances are separated by gravity sedimentation. The removal is being measured. However, with this method, sludge-like particles with a high specific gravity can be removed,
A scum-like substance mainly composed of oil having a low specific gravity has a disadvantage that it cannot be removed. This scum-like substance floats in the form of a thin film on the liquid surface of the cleaning liquid. Has become.

The present invention has been made in view of the above-mentioned problems of the prior art, and efficiently removes a scum-like substance mainly composed of oil floating on the liquid surface of a cleaning tank to improve the cleaning effect. It is an object of the present invention to provide an agitation type cleaning apparatus capable of increasing the number of times of using a cleaning liquid stuck in a cleaning tank and reducing the consumption thereof.

[0005]

In order to solve the problems] Toko to the gist of the present invention
In a stirring type washing apparatus for washing an object to be washed inserted into the washing tank by driving stirring blades provided opposite to left and right end walls of the rectangular washing tank, one end of the washing tank is provided. The lower part is immersed in the liquid surface near the wall to set up the oil skimmer, and the surface oil flowing toward the oil skimmer is generated by the stirring blade of the other end wall to remove floating oil. a mold cleaning apparatus, and the considered
Well-known belt type oil skimmer used in the plan
Or the use of a rotating disk type is preferable, especially a steel bell
G oil skimmers are preferred.

[0006]

[Function] The lower surface is immersed in the liquid surface near one end wall of the washing tank to generate a surface flow which flows toward the oil skimmer which is erected, and a thin film of oil floating on the liquid surface and the oil skimmer are generated. The oil is efficiently recovered by contact. In the first invention, the surface flow is generated by slowly rotating only the stirring blades on the end wall opposite to the end wall provided with the oil skimmer, and in the second invention, the surface flow is also generated on the opposite end wall. The liquid surface is swept away by an air flow flowing out of an air blow-off pipe installed horizontally near the water surface, and is generated. As the oil skimmer, a steel belt type oil skimmer is preferable, and when one of the endless belts suspended vertically from the upper and lower pulleys rises from the liquid, the film-like oil floating on the liquid surface adheres. to recover.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the contents of the present invention will be further described based on embodiments. FIG. 1 is a plan view of a stirring type cleaning apparatus according to the present invention,
FIG. 2 is a longitudinal sectional view of FIG. In the figure, reference numeral 1 denotes a main body of a rectangular cleaning tank, and propeller-type stirring blades 2 and 2A are horizontally mounted on left and right end walls. Reference numeral 3 denotes a belt-type oil skimmer erected along the left end wall of the washing tank 1. A lower pulley and a part of the belt are immersed in a liquid, and the belt is moved in the direction of the arrow by an electric motor 4 connected to the upper pulley. Is driven. Reference numeral 5 denotes a wiper blade which comes into contact with the surface of the descending belt to scrape off the oil adhering to the belt.
Is in contact with Reference numeral 8 denotes an air blowing pipe which is horizontally installed along the right end wall of the cleaning tank 1, and is fixed to a pair of brackets fixed to the end wall with U bolts (not shown).
A plurality of air holes (not shown) are provided in the lower half of the air blowing pipe 8.
Are formed in a line in the pipe axis direction, and the air blown out from the air holes flows parallel to the liquid surface. Reference numerals 9 and 9A denote guides disposed on both left and right end walls of the washing tank so as to surround the stirring blades 2 and 2A, respectively, and have a shape for forming a liquid flow pattern in the washing tank.

The operation of the embodiment having the above configuration will be described. The driving of the stirring blades 2 and 2A causes the cleaning liquid to flow at a high speed, and removes oil, dust, and the like from the mechanical components installed in the cleaning tank. An oil layer is formed on the surface of the cleaning liquid as the cleaning proceeds, and is removed in the following procedure.
The operation of the stirring blades 2 and 2A is stopped, and the washing liquid is allowed to stand still to stabilize the oil layer. The operation of the oil skimmer 3 is started, and the belt is driven in the direction of the arrow. Next, facing oil skimmer 3
Slow rotation of only the stirring blade 2 on the end wall side to generate surface flow
To push the oil layer on the liquid surface in the direction of the oil skimmer 3
And make efficient contact with the belt. The oil adhering to the belt rising above the liquid level is inverted by the upper pulley and descends, then comes into contact with the wiper blade 5 and is scraped off, and is collected in the oil tank 7 via the gutter 6. In the above embodiment
In this case, the surface flow of the liquid surface is reduced by the slow stirring of the stirring blade 2.
Triggered, but blows out pressurized air from air blow-off pipe 8
And a superficial flow is generated by flowing an air flow parallel to the liquid surface.
Good, but the power cost and installation of the compressor for generating compressed air
Since the cost is high, only the stirring blade 2 is rotated slowly to reduce the surface flow.
It is preferably generated.

[0009]

According to the present invention having the structure and operation described above, the oil layer on the liquid surface of the stirring type cleaning tank can be efficiently removed, so that the cleaning effect can be improved and
The effect of reducing the consumption of the cleaning liquid can be obtained.
