Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an oil drainer for efficiently draining excess oil applied to a rod while the rod is being conveyed to the next step. It concerns the device.

[Conventional technology]

The polished rod is protected by applying an oil film to the surface.

In order to apply an oil film to a rod such as a polish rod, a bundle of many rods is immersed in an oil tank by a crane for a certain period of time, and then a large number of rods are laid diagonally while standing up. By leaving it for a time, the excess oil applied to the bar is dropped by gravity to perform oil draining.

As described above, since excess oil applied to the bar is naturally dropped by gravity action to perform oil removal, it takes time for oil removal, and also a work of bundling and unbinding a large number of bars. Became indispensable, and it was not possible to automate the oil draining operation of the surplus oil applied to the bar.

The present invention has been made in view of such a problem of the related art, and in the course of transporting the bar from the oiling process to the next process, by performing oil removal of excess oil applied to the bar,
The purpose is to automate this oil draining operation.

[Means for solving the problem]

The oil draining device according to the present invention is configured such that an oil draining net having a configuration in which the net body is gently inclined so as to become lower in the direction of transport of the bar and stretched is connected to the discharge side of the oiling device, The gist is that a blower is provided above the net and an oil receiver is provided below.

[Function of the invention]

The lubricated bar is sent from the lubricator to an oil-draining net that stretches the net, and the excess oil that has been applied while the bar is rolling on the inclined surface of the oil-draining net is meshed with the mesh. Attached to the part.

A blower is provided above the oil-draining net, and is constantly blown downward from the blower. The oil adhering to the mesh portion of the net body is immediately blown down by the blowing pressure, so that the oil is collected below the oil catcher. To be housed. For this reason, the mesh of the net constituting the oil netting does not become clogged with oil, and the surplus oil that has been applied is drained while the bars are conveyed one by one.

〔Example〕

FIG. 1 is a side view of an oil draining device C according to the present invention, FIG.
Figure plan view of the same, FIG. 3 is an enlarged partial plan view of a state in which the inclined surface of the oil thrower network C ₁ is the bar B are rolling, FIG. 4 is a similarly enlarged side view.

The oil removing device A is connected to the oil removing device C for the bar B according to the present invention.

The oiling device A is provided with a plurality of skid devices in which a fixed skid 4 and a movable skid 6 are juxtaposed and arranged in the oil tank 2 at predetermined intervals in a direction perpendicular to the transport direction P of the bar B. It is. Oil is applied while the rod B is slowly conveyed in the oil 8 stored in the oil tank 2 by the vertical movement of the movable skid 6.

The lubricated bar B rolls on a carry-out guide 10 provided at the carry-out end of the oil tank 2 and is fed into the oil draining device C.

The oil draining device C has a large number of rectangular nets 12 arranged side by side in a direction perpendicular to the transport direction P of the bar B.
Gently inclined to become lower toward the conveying direction P of the oil thrower network C ₁ which stretched as no slack, a blower C ₂ provided directly on oil thrower network C _1, oil thrower network oil pan provided directly under the C ₁ composed of C ₃ Prefecture.

Blower C _2, a large number are provided along the conveying direction P perpendicular to the direction of the bar B, and are blown continuously at a predetermined feed air pressure downward.

The net body 12 constituting the oil drain net C ₁ is provided with a tension bolt 14
It is stretched so as not to be loosened by the action of. As shown in FIG. 2, a large number of square nets 12 are formed.
Is slightly with respect to the transport direction P of the bar B so that when the bar B is rolled and transported, all portions along the longitudinal direction of the bar B contact the net 12. It is inclined.

In FIG. 1, reference numeral 16 denotes a wind shield plate for preventing the blow from the blower C ₂ from reaching the carry-out guide 10;
Denotes an unloading device for unloading the bar B passing through the oil draining device C.

The bar B sent out from the oiling device A rolls on the unloading guide 10 and enters the oil draining device C. Outlet guide 10 and oil thrower network C ₁ is connected to so as to slope gently lower toward the conveying direction P of the bar B, the oiled been bar B constitutes the oil thrower network C ₁ While rolling the inclined surfaces of the large number of meshes 12 under their own weight, surplus oil 18 applied to the outer peripheral surface adheres to the mesh 12a of the mesh 12, thereby coating the rod B. The oiled surplus oil 18 is drained.

From the blower C ₂ are performed blown constantly downward, the excess oil 18 adhering to the part of the mesh 12a of the mesh body 12 by the feed air pressure is housed in the C ₃ receives oil downward immediately blown dropped As a result, it is possible to prevent the surplus oil 18 attached to the mesh 12a of the mesh body 12 from clogging the mesh 12a.

As a result, even if the bar B coated with oil on the mesh body 12 continuously rolls, the oil is drained without any trouble.

The oil applicator of the above embodiment has a configuration in which a large number of skid devices including a fixed skid 4 and a movable skid 6 are immersed in the oil tank 2, but the oil applicator is not limited to this and may have any configuration. Is also good.

〔The invention's effect〕

The present invention relates to a method for rolling a bar coated with oil along an inclined surface of a grease net having a configuration in which a net body is inclined so as to become lower toward a direction in which the bar is conveyed. The surplus oil applied to the material adheres to the mesh part of the net, and the oil adhering to the mesh part is immediately blown down by the blowing pressure of the blower provided just above the oil-draining net. Therefore, surplus oil can be drained during the transportation of the lubricated bar to the next step.

For this reason, after applying oil to the bar by the oiling device, excess oil applied to the bar is cut off by the oil draining device while the oiled bar is transported one by one to the next process. With this configuration, it is possible to automate the operation of draining excess oil applied to the bar.

Furthermore, since the oil gauze net is fixed, except for the power of the blower, it is possible to perform the oil grease for the surplus oil applied to the surface of the bar without any other power. The running cost required for oil removal of the bar becomes extremely low.
