Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating oil removing apparatus for removing only oil from a cleaning liquid recovered in a storage tank after cleaning a work.

[0002]

2. Description of the Related Art For example, an engine valve is manufactured into a product through various machining processes. During the process,
A cleaning process may be provided to remove oil such as cutting oil attached to the work.

The water-soluble cleaning liquid used in the cleaning process is
Usually, after the work is washed, it is collected in a storage tank to remove oil, and then repeatedly used several times. At this time, unless the oil is completely removed before use, the oil mixed in the cleaning liquid adheres to the cleaned work again.

Therefore, conventionally, an operator scoops off oil components floating on the surface layer of the cleaning liquid collected in the storage tank by a container or the like, or a gutter is provided on the upper portion of the storage tank. For example, floating oil is drained and removed.

[0005]

In the above-described removal work, not only the labor can not be saved, but it is difficult to remove only the oil component, and the cleaning liquid is also discharged at the same time. It is uneconomical to replenish the cleaning liquid up to a predetermined amount as needed.

The present invention has been made in view of the above problems. By automatically removing only the oil component from the storage tank, labor can be saved and the reduction of the cleaning liquid can be minimized. Another object of the present invention is to provide a floating oil removal device.

[0007]

According to the present invention, the above object is to provide a disc, which is linked to drive means and rotates around a horizontal axis, at the upper end of a storage tank for a liquid containing oil, the lower end thereof. A drainage oil that is provided so that the outer peripheral portion is poured into the liquid, and scrapes off the oil content adhering to it by contacting both sides of the disk at the appropriate position on the downward rotating part side of the disk and discharging it downward. It is solved by providing a gutter.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, in the storage tank (1), an oil-containing water-soluble cleaning liquid (2) used in, for example, a cleaning process of a work is collected and stored.

The upper surface of the support plate (3) fixed to the upper open end of the storage tank (1) so as to cover the latter half (hereinafter, the right side of FIG. 1 is described as the front) is fixed to A variable speed motor (5), which is integrated with a gear head (4) accommodating a reduction gear (not shown), is fixed by a bracket (6).

On the horizontal drive shaft (7) of the motor (5),
A metal disk (8) is fixed so that the outer peripheral portion of the lower end thereof is immersed in the cleaning liquid (2) in the storage tank (1). The disc (8) is slowly rotated counterclockwise in a front view by the motor (5).

At the upper part of the left side plate in the storage tank (1), a pair of front and rear oil drain gutters (9) which are inclined downward in the left-right direction.
(9) is fixed by a Y-shaped bracket (10) so as to sandwich substantially the middle portion of the downward rotating portion of both left side surfaces of the disk (8).

Each oil drain gutter (9) is composed of an elongated plate material (9a) (9b).
A portion of the plate material (9b) located on the side of the disk (8) facing the both surfaces of the disk (8) is formed into a V-shape when viewed from the side, and is formed so as to form a V groove. A pair of thin-walled oil removing plates (11) inclined inwardly are fixed so that the upper ends thereof contact both surfaces of the disk (8).

Reference numeral (12) is an oil storage container installed just below the lower end of the drain gutter (9). In the device of the above embodiment, the motor
When the disk (8) is rotated at a slow speed by the operation of (5), the oil (13) floating in the upper layer of the cleaning liquid (2) in the storage tank (1)
Is shunted around both sides of the disk (8) and scraped off at the position of the oil removal plate (11) in the drain gutter (9). The scraped oil is discharged downward through the V groove of the drain gutter (9) and falls into the oil storage container (12) to be collected.

At this time, the cleaning plate (2) is attached to the disc (8).
, But the cleaning liquid (2) has a larger specific gravity than oil,
And since the viscosity is small, the disk (8) almost flows down while rotating at a slow speed, and only the floating oil (13) is stored in the oil storage tank.
Removed from (1). The present invention is not limited to the above embodiment. For example, in the embodiment, the oil removing plate (11) is provided integrally with the drain gutter (9), but it may be provided separately using an appropriate bracket, or the oil removing plate (11) itself. May be formed as a long and gutter-shaped gutter to form an oil drain gutter.

Both sides of the disk (8) may be coated with a material having a good affinity for oil, which improves the adhesion of the oil (13) and enhances its removal effect.

[0016]

According to the present invention, only the oil content is automatically removed from the liquid in the storage tank by simply rotating the disc, so that the liquid such as the cleaning liquid can be reused. Also,
Unlike the conventional case, it is not necessary to manually remove the oil component or to remove the oil component using a gutter, so that labor can be saved and the liquid is not required to be replenished.
