In the following embodiments, the same reference numerals are assigned to the same components for convenience.

1 is a perspective view of a waste oil filtering device according to an embodiment of the present invention, FIG. 2 is a perspective view of a rotating cover part opened in FIG. 1, FIG. 3 is a perspective view of a waste oil filtering device from which a cover and a spin basket are removed. 4 is a perspective view of the spin basket, and FIG. 5 is a schematic cross-sectional view of FIG. 1.

As shown in these figures, the waste oil filtering device of the present embodiment, the apparatus housing 100, the spin basket 200, the rotary drive unit 300, the cover 400, and the waste oil supply line 500 Include.

The device housing 100 forms the appearance of the device. The device housing 100 has a cylindrical shape because the spin basket 200 is mounted to rotate inside the device housing 100. However, the device housing 100 does not necessarily have a cylindrical structure.

The apparatus housing 100 forms a working space for filtering waste oil to separate pure oil and sludge including moisture in the waste oil. Here, pure oil means that it can be reused as necessary, but reuse is not necessarily a condition.

The waste oil filtering device of the present embodiment is separated from the waste oil into three types: first pure oil having a small specific gravity, a second pure oil having a larger specific gravity than the first pure oil, and waste sludge. Of course, alternatively, a structure for dividing pure oil and sludge from waste oil may be adopted, which is also within the scope of the present invention.

The device housing 100 may be made of relatively strong stainless steel because it is connected to other structures such as the spin basket 200 is rotatably mounted therein and the cover 400 is coupled thereon.

Looking at the device housing 100 having a cylindrical structure by position, the device housing 100 is divided into a bottom surface 111 and a side 112.

The first pure oil discharge hole 113 and the second pure oil discharge hole in which the first pure oil, the second pure oil, and the sludge are discharged through different paths are respectively disposed on the bottom surface 111 of the apparatus housing 100. 114, and the sludge discharge hole 115 is formed.

Looking at these positions, when looking at the bottom surface 111 of the device housing 100 in a planar state, the first pure oil discharge hole 113 is located at the outermost in the radial direction, and then the second Pure oil discharge hole 114 is located, the sludge discharge hole 115 is located inward. This corresponds to an optimal structure that can more effectively filter and separate the first pure oil, the second pure oil, and the sludge as described below.

A partition wall 116 is formed on the bottom surface 111 of the apparatus housing 100 to stand up toward the cover 400 in an area between the first pure oil discharge hole 113 and the second pure oil discharge hole 114. The partition wall 116 has a slightly inwardly inclined shape as shown in FIG. 5, but does not need to be the case. And the height of the partition wall 116 is formed lower than the side 112 of the device housing 100 to prevent interference with the cover 400.

An isolation rib 117 is further formed on the bottom surface 111 of the device housing 100. The isolation rib 117 serves to isolate the sludge discharge hole 115 and the second pure oil discharge hole 114 from each other.

Side 112 of the device housing 100 is provided with a plurality of latches 120 for attaching and detaching the cover 400 with respect to the device housing (100).

The side 112 of the device housing 100 is provided with a plurality of legs 130 supporting the device housing 100 with respect to the ground. An end of the leg 130 is coupled to the rolling wheel 140 for moving the device housing 100 to a desired position easily. At this time, it is preferable that a brake (not shown) is further provided on the rolling wheel 140 to limit the movement of the rolling wheel 140 as necessary.

As shown in FIG. 4, the spin basket 200 is rotatably mounted in the apparatus housing 100 to substantially separate waste oil into first and second pure water oil and sludge based on centrifugation. Play a role. Since the spin basket 200 is a rotating body that is rotated by thousands of RPM, it may be made of, for example, a relatively light material of aluminum.

The spin basket 200 extends toward the cover 400 at an end of the disk-shaped basket bottom wall 201 and the partition bottom wall 201, and forms a space S between the partition wall 116. The basket side wall 202 and the basket upper wall 203 is disposed in parallel with the basket lower wall 201 at the upper end of the basket side wall 202 and one side is placed on the upper end of the partition wall 116.

As shown in FIGS. 4 and 5, at least one sludge discharge hole 205 is formed in the basket lower wall 201. This basket bottom wall 201 is located in close proximity to the isolation ribs 117 formed in the bottom surface 111 of the device housing 100. Accordingly, the sludge present at the bottom of the spin basket 200 during or after the filtering operation is sludge discharge pipe 115a via the sludge discharge holes 205 and the sludge discharge holes 115 as shown in FIG. 5C. To be discharged.

When the spin basket is rotated, the basket sidewall 202 is formed with a second pure oil discharge hole 206 through which a second pure oil having a specific gravity higher than that of the first pure oil can be discharged. At least one second pure oil discharge hole 206 may be formed in the same manner as the sludge discharge hole 205. In the present embodiment, the basket side wall 202 is configured to gradually increase the radial width from the area in contact with the basket bottom wall 201 and the basket top wall 203 toward the center area, but is limited to this configuration. no. Meanwhile, the second pure oil filtered in the spin basket 200 during the filtering operation may include the plurality of second pure oil discharge holes 206, the separation space S, and the second pure oil as shown in FIG. 5B. The second pure oil discharge pipe 114a is discharged through the discharge hole 114.

The basket upper wall 203 has an opening 203a through which waste oil from the waste oil supply line 500 flows. The opening 203a of the basket upper wall 203 is a place where the waste oil flows in, but is also a place where the first pure oil is discharged. A flange portion 203b extending upward is formed at the inner leading end portion of the basket upper wall 203. Accordingly, during the filtering operation, the first pure oil filtered in the spin basket 200 overflows through the opening 203a of the basket upper wall 203 as shown in FIG. Through the first pure oil discharge hole 113 is discharged to the first pure oil discharge pipe 113a.

Inside the spin basket 200, one end thereof is connected to the rotation driving unit 300, and the other end thereof is provided with a rotation shaft 210 that rises upward. The rotating shaft 210 has a conical shape, the surface of the rotating shaft 210 is formed with at least one stirring rod 220 to help agitate the waste oil. Stirring rod 220 may be spaced apart from each other at equal intervals along the circumferential direction of the rotating shaft (210).

The rotary drive unit 300 is coupled to the device housing 100, as shown in Figure 5, one side is connected to the spin basket 200 serves to rotate the spin basket 200. Although a conventional motor may be used, in the present embodiment, the rotation driving unit 300 may be applied as an air motor to stably support the spin basket 200 while rotating the spin basket 200 at high speed.

The lid 400 opens and closes the upper opening of the device housing 100. It may also be made of an integral plate-like body that is not separated. However, in the present embodiment, the cover 400 is rotated with respect to the fixed cover portion 410 and the fixed cover portion 410 by the hinge 430 to rotate the cover portion 420 for opening and closing the device housing 100 It is prepared to have.

In the present embodiment, the fixed cover portion 410 is made of a metal material, and the rotating cover portion 420 may be made of transparent or translucent tempered glass capable of seeing inside, but this is exemplary, so limited only to such a configuration no.

Finally, the waste oil supply line 500 is coupled to the lid 400, in particular the fixed lid portion 410, to supply waste oil to be filtered to the inside of the spin basket 200. Of course, unlike the drawing, the waste oil supply line 500 may be connected to the rotation cover portion 420 or may be connected to the apparatus housing 100 to supply waste oil to the inside of the spin basket 200.

Although not shown, the waste oil supply line 500 may be further connected to a waste oil processor for changing the waste oil into a state suitable for centrifugation. For example, if the viscosity of the waste oil is too high, since it is difficult to separate into pure oil and sludge only by centrifugation, the waste oil treatment machine may be subjected to a suitable degree of viscosity.

The operation of the waste oil filtering device having such a configuration will be briefly described as follows.

Waste oil is supplied to the waste oil receiving space of the spin basket 200 through the waste oil supply line 500. At the same time or at the same time, the spin basket 200 starts rotation by, for example, thousands of RPM (RPM) by the rotary drive unit 300.

Then, when the waste oil is separated into the first pure oil, the second pure oil and the sludge by the difference in density due to the centrifugal force generated in the waste oil, each is discharged along the following path.

First, the lightest first pure oil flows through the opening 203a of the basket upper wall 203 as shown in FIG. 5A when the spin basket 200 rotates, and then moves to the outside of the partition 116. Through the first pure oil discharge hole 113 is discharged to the first pure oil discharge pipe 113a.

The second pure oil heavier than the first pure oil passes through the plurality of second pure oil discharge holes 206, the separation space S, and the second pure oil discharge hole 114 as shown in FIG. 5B. To be discharged to the second pure oil discharge pipe 114a.

Meanwhile, the sludge with the highest specific gravity is discharged to the sludge discharge pipe 115a via the sludge discharge holes 205 and the sludge discharge holes 115 as shown in FIG. 5C.

This series of filtering operations can proceed continuously while the waste oil is supplied.

Thus, according to this embodiment, it is possible to effectively separate the pure oil and sludge containing water in the waste oil while having a simple and simple structure.

It is the same in all respects as the structure of the above-mentioned embodiment except that 211 is additionally included.

One end of the pushing switch 600 is disposed in the device housing 100 adjacent to the rotating shaft 210 to select whether or not to rotate the spin basket 200 based on a pressurizing or depressurizing operation. If the switch 600 is provided it may be convenient to operate the waste oil filtering device.

Also, the pushing switch 500 is operatively connected to the wire 211. That is, as the pushing switch 500 is pressed or released, the wire 211 and the pushing switch 500 are operatively connected to open or close the opening / closing portion 213. For example, when the pushing switch 500 is pressed, the spin basket 200 is rotated, and the wire is operated so that the opening and closing portion 213 opens the through hole 206.
