Abstract

PROBLEM TO BE SOLVED: To provide a high performance, inexpensive cyclone separator by arranging a cap consisting of a cylindrical part having an inflow port and an inner cylinder inserting through a top plate for closing the cylindrical part in the upper part of a main body part consisting of glass or the like integrally having a conical part in the lower part of a cylindrical shell part. SOLUTION: A cutting oil containing turnings is forcibly fed to a main body part 1 from an outside inflow part 14 through an inflow pipe 3 and a cap 2 and is turned in the main body part 1. Turnings of large mass are transferred to the outer peripheral part of the main body part 1, a cutting oil not containing tunings, that is, a clean cutting oil of small mass is transferred to an axial center part of the main body part 1. After that, cutting oil containing a lot of turnings of large mass sinks along the outer peripheral part of a comical part 1b by gravity and flows out to the outside from the lower end part thereof through a discharge pipe 20. On the other hand, after the clean cutting oil of small mass moves upward in an inner cylinder 4 and flows out to the upper part of a case 10, it flows out to outside the case 10 from an outside outflow pipe 16. By the way, the main body part 1 is formed of glass or porcelain to improve corrosion resistance and surface smoothness thereof.

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, FIG. 1 is a cross-sectional view showing an embodiment of the present invention, FIG. 2 is a II-II cross-sectional view thereof, and FIG. 3 is a cross-sectional view showing a manufacturing procedure of a main body portion. In FIG. 1, reference numeral 1 denotes a glass or porcelain main body portion, the upper portion of which is formed into a cylindrical body portion 1a having the same diameter, and the lower portion of which is formed into a conical cylindrical portion 1b having a small diameter that is smooth downward. It becomes. This main body 1 is
In this example, as shown in FIG. 3, the bottom of an empty bottle 1 ', such as an empty bottle, a beer bottle, or a porcelain vase, is cut along the line AA and is arranged upside down. .

A metal cap 2 is provided on the upper portion of the body 1a.
Is fitted and fixed via a cushion material 6 such as an O-ring.
As shown in FIGS. 1 and 2, the cap 2 has a cylindrical top plate 2b that closes the upper surface of a cylindrical portion 2a of an end scale formed to have a diameter substantially equal to that of the body portion 1a of the main body 1 to form a cylinder. A small-diameter inflow pipe 3 is tangentially connected to the portion 2a, and a small-diameter inner cylinder (outflow pipe) 4 is vertically passed through the central portion of the top plate 2b, and its upper end is fixed to the top plate 2b. Become.

The body 1 and the cap 2 are surrounded by a metal or plastic case 10 having high impact resistance. The case 10 has a peripheral wall 10a formed in a cylindrical shape having a diameter larger than that of the main body 1 described above, and its upper and lower surfaces are closed by upper and lower surface plates 10b and 10c to form a hermetically sealed state. Four radial support plates 11 are attached to the upper part of the case 10, the outer periphery of the cap 2 is held by the inner end of the support plate 11, and the support tube 12 is provided at the center of the lower plate 10c of the case 10. Is attached, and the lower end of the main body 1 is fitted and held on the support tube 12 via a cushion material 13 such as sponge.

The external inflow pipe 14 is attached to the upper part of the peripheral wall 10a of the case 10, and the upper part is penetrated into the peripheral wall 10a to be connected to the inflow pipe 3 of the cap 2 described above. Cutting oil obtained by cooling and cleaning a cutting tool or a cutting tool of a machine tool is pressure-fed to the external inflow pipe 14. Further, an external outlet 15 is formed on the outer peripheral portion of the lower surface plate 10c of the case 10, and an external outlet pipe 16 is connected to the external outlet 15.
Reference numeral 17 is an air suction pipe for introducing outside air into the case 10, and extends in the vertical direction in the case 10.
The upper end is bent downward in the upper part of the case 10 and then opened in the case 10, and the lower end is opened to the outside through the lower plate 10c.

In FIG. 1, reference numeral 20 denotes a discharge pipe connected to the lower end of the main body 1 via the support pipe 12, and a pipe joint 21 for holding the support pipe 12 is provided at the center of the lower plate 10c. It is detachably connected to the lower portion of the pipe joint 21. Two
Reference numeral 2 is a pressure gauge mounting tube provided on the upper surface plate 10b.

According to the above-described embodiment, the cutting oil pressure-fed from the inflow pipe 3 to the main body 1 through the external inflow pipe 14 is swirled in the main body 1 and the cutting powder having a large mass is removed from the main body 1. The cutting oil containing no cutting chips, that is, the clean cutting oil having a small mass is transferred to the axial center portion of the main body 1. Then, the cutting oil containing a large amount of cutting chips having a large mass sinks along the outer periphery of the conical cylinder portion 1b due to gravity, flows out from the lower end thereof through the discharge pipe 20 to the outside, and has a clean cutting having a small mass. The oil moves upward in the inner cylinder 4 and flows out to the upper part in the case 10, and then flows out of the case 10 from an external outflow pipe 16 provided in the lower part of the case 10.

In this case, since the main body 1 is made of glass or porcelain, it is excellent in erosion resistance, and the surface is smooth and hard so that cutting oil does not easily adhere and the resistance becomes small. . Further, since the boundary between the cylindrical body 1a and the conical cylinder 1b is streamlined, turbulence does not occur at the boundary. For this reason, the swirling flow is efficiently generated in the main body portion 1, and the generated swirling flow is less likely to be attenuated, so that the separation performance is improved. In addition, the surface is not easily scratched by solid matter such as cutting chips, and the separation performance is maintained good for a long period of time. Further, since the main body 1 can be formed by using a commercially available empty bottle, it is possible to reuse resources and obtain it at low cost.

Further, since the main body 1 and the cap 2 are surrounded by the case 10 having high impact resistance, obstacles and the like do not directly collide with each other, and damage and damage due to the obstacles and the like are prevented. Become. When the cutting oil is not supplied from the external inflow pipe 14 and the operation is stopped, the outside air is supplied from the air suction pipe 17 into the case 10, and the cutting oil in the case 10 is discharged from the outflow pipe 16 to the case 10. It is leaked out.
