Description

[Detailed Description of the Invention] The present invention relates to a centrifugal separator, particularly a deoiling machine that separates lubricating oil from chips generated during cutting, and enables the recovered lubricating oil to be reused.

This type of conventional deoiling machine is a repurposed centrifuge.
Either the oily chips are directly put into a rotating container in a centrifuge (for example, Patent No. 146727), or an auxiliary container such as a bag or assembly section filled with oily chips is placed in the rotating container. Either rotate the rotary container in the housed state, or detachably attach the assembly directly to the rotary drive shaft as shown in Japanese Patent Publication No. 45-563, and then rotate the drive shaft in this state to separate the oil. I was trying to do that.

However, in the former case, in which the chips are directly put into the rotating container, it takes time to remove the chips after deoiling, and in the latter case, in which an auxiliary container such as a bag or mesh basket is used, it is difficult to remove the chips. The work is simple as it can be done with the auxiliary container, but
The undeoiled cuttings collected from the workshop had to be transferred into the auxiliary container and replaced, which was troublesome.

As mentioned above, it is necessary to transfer the chips before oil removal to the auxiliary container because if the auxiliary container is also used as a chip collection container, most of the oil will leak out from the mesh when collecting the chips. This is because

This invention eliminates the need to transfer the chips before deoiling from the chip collection container to the auxiliary container, so even if the auxiliary container is used as a chip collection container, oil will leak during chip collection. The challenge is to prevent this from happening.

The technical means of the present invention for solving the above problems is to use a bale can as an auxiliary container that is removably installed in the body of a deoiling machine, and to have an outwardly convex rib wound around the top of the bale can. The depth of the waist-rotating container is made similar to the depth of the bale can by having a through hole bored therein, and is less than or equal to the depth to the rib of the bale can.

According to the above technical means of the present invention, when the bale can filled with cuttings is attached to the rotating container of the machine and driven, the oil adhering to the cuttings will cause the tapered surface of the bale can to be moved by centrifugal force. It rises towards the large top and eventually reaches the ribs provided above.

A through hole is formed in the rib, and the oil is discharged through the through hole.

Furthermore, when the above bale can is used for cutting shoulder circumference,
Since the bale can only has holes in the ribs located at the top, there is no fear of oil leakage even if the bale can is left containing chips containing lubricating oil. Bale cans in the same condition as they were collected can be directly run through a deoiling machine.

Since the present invention has the above configuration, it has the following unique effects.

(1) Since the bale can used as an auxiliary container can also be used as a swarf collecting container, the bale can that has collected the swarf can be put directly into the deoiling machine. This eliminates the need for the conventional work of transferring chips to an auxiliary container dedicated to the deoiling machine.

Further, when the container is used as a chip collection container, the container may be left with the chips stored therein, but even in this case, the oil accumulated at the bottom will not flow out.

(2) Although the bale can used as an auxiliary container has a thin wall as a whole, the through holes for oil drainage are provided in the ribs, so the reinforcing effect of the ribs itself compensates for the decrease in strength due to the through holes, and the other parts Compared to the case where a through hole is provided, the reduction in strength in the radial direction due to the provision of a through hole is reduced.

(3) If the through hole for oil drainage is drilled in a place other than the rib, there is a problem that oil will accumulate inside the rib during oil removal and it will not be possible to remove oil sufficiently. Since the through holes are provided in the rib portions, oil does not remain inside the ribs, thereby eliminating the above-mentioned inconvenience.

(4) Since the bale can used as a packaging container for cutting oil can be used as an auxiliary container as it is after being used, the bale can, which is difficult to dispose of, can be used effectively.

Next, embodiments will be described.

An embodiment in which the rotating container in the fuselage that accommodates the auxiliary container is located in the middle of the fuselage, and the oil outlet is provided at a position higher than the height of the auxiliary container. The through hole of the auxiliary container to be accommodated is located at the top of the aircraft, and the oil outlet is located above the height of the auxiliary container, so the auxiliary container (bale can) used as a deep-bottomed container can be used as is as an oil container. can.

Hereinafter, embodiments of the present invention will be described based on the drawings.

The auxiliary container used in the deoiling machine of the embodiment of the present invention is a bale can shaped as shown in Figure 1, which is used as a packaging container for lubricating oil, etc., and is usually unnecessary after the lubricating oil is used. ,
It has been disposed of.

This bale can has a tapered cross section that expands upward, and has ribs 1 and 1 wound outward in the upper part in a convex manner, and a handle 2 is connected to the upper end. has been done.

In the embodiment of the present invention, a plurality of through holes 3, 3 are formed in the ribs of this bale can.

Next, to explain in more detail the structure of the main body of the deoiling machine according to the embodiment of the present invention shown in FIG. A rotating shaft 5 fixed to the bottom, a middle case 6 fixed to the rotating shaft and fitted from below the outside of the rotating container 4, and a middle M7 that covers the middle case 6 and covers the auxiliary container. It consists of an outer cover 8 and an outer case 11 which is fitted from below the inner case 6 and swingably supports a support shaft 9 at its bottom via rubber 10 and 10.

In the above, the outer cover 8 is connected to the upper end of the enlarged diameter part 12 at the upper part of the inner case 6 in a single-opening manner, and opens and closes about the fulcrum 13, and engages with the free end side. It is locked in the closed state by the coupling device 14.

Further, the inner lid 7 is rotatably connected to the center of the outer lid 8, and when the outer lid 8 is in the closed state, the inner lid covers the upper end opening of the auxiliary container A in the housed state.

The depth of the rotary container 4 is set appropriately in advance, and when the auxiliary container A is accommodated, the upper ribs 1, 1 are located further above the rotary container 4, and the depth of the rotary container 4 is A collar 15 is made to protrude from the upper end, and its outer peripheral edge faces above an annular groove 16 formed in the enlarged diameter portion 12 of the inner case 6.

In addition, an oil outlet 17 is provided in the enlarged diameter portion 12 of the middle case 6.
is provided.

Next, the rotating shaft 5 is paired with a supporting shaft 9, and rotational driving force is transmitted to the rotating shaft from a drive source such as a motor, and a rotating container 4 connected to the rotating shaft and an auxiliary object housed therein are connected to the rotating shaft 5. The container A and the inner lid 7 are rotated together.

On the other hand, the support shaft 9 is provided with a pot 18 held between an annular rubber 10 and 10, and is held in a free state by the rubber housed in a cylinder chamber 19 under pressure. It is possible to swing the head.

Incidentally, on the upper and lower sides of the collar 18, cylindrical bodies 20, 20 that can slide on the support shaft 9 within a minute range are fitted, and the rubber 10.1 in these parts is fitted.
0 and the support shaft 9 are avoided.

To explain in more detail the operation described above, when the outer lid 8 is open, the auxiliary container A can be taken in and taken out, and the auxiliary container A, which is provided near the cutting machine and contains chips, can be placed in this open state. , it can be inserted into the rotating container 4 as it is.

After insertion, when the outer lid 8 is closed and the engagement device 14 is engaged, the outer lid is fixed, and at the same time the inner lid 7 covers the auxiliary container A.

Here, when an oil recovery container is placed at the oil outlet 17 and the drive source is rotated, the auxiliary container A is rotated together with the rotating shaft 5, that is, the rotating container 4, and the chips in the auxiliary container are The lubricating oil that has adhered to it is washed away by the centrifugal force.

Since the auxiliary container A has a tapered shape that expands upward, the lubricating oil that has reached the side wall of the container is flowed upward by the upward component of the centrifugal force and is stored in the ribs 1,1.

However, since the ribs are provided with through holes 3, 3, the lubricating oil stored in the ribs is discharged from these through holes and comes into contact with the inner wall of the body 21 of the outer lid 8, and then flows into the inside. It flows down into the annular groove 16 in the upper part of the case 6.

After that, the lubricating oil stored in the annular groove 16 is transferred to the oil outlet 17.
taken from.

The lubricating oil is separated and taken out from the chips by the above action, but during this operation, if the balance inside the auxiliary container A is not maintained, the rotating shaft 5 and the supporting shaft 9 will oscillate. , this is the rubber 10.10 that holds the support shaft 9.
absorbed by.

In addition, in the case of the illustrated embodiment, the support shaft 9 contacts the rubber 10.10 via the cylindrical body 20.degree. There is no movement, which reduces heat generation and wear in the area.
