CONSTITUTION: A cylindrical rotary body 1 wherein a roller 2 is arranged coaxially with that of a cylindrical body on the outer periphery of a cylindrical body is horizontally installed, the roller 2 is rotatably supported by a plurality of support rollers 3 a part of which are immersed in lubricating oil in an oil tank 4. In this case, oil removing rollers 5 to remove surplus lubricating oil from the support rollers 3, and an oil removing roller 6 making contact with the side of the roller 2 and rotated following rotation of the roller are provided. The roller 6 is attached to the lowermost part of the roller 2 and removing oil is dropped in the oil tank 4 without flying of removed oil. A cover 7 is provided to partially cover the oil removing rollers 5 attached to the support rollers 3 and prevent flying of removed oil.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of supporting a cylindrical rotary member such as a drum dryer. In particular, the present invention relates to a bearing method capable of reducing oil contamination of the surroundings.

[0002]

2. Description of the Related Art Since a drum dryer and a drum granulator can be continuously operated and can be processed in large quantities, they have been widely used as a drying device or a granulating device in various processes. These devices are located at several locations along the length of the cylindrical body,
Rollers are concentrically mounted along the outer periphery of the roller, and the roller is supported by a small supporting roller, and the supporting roller is driven to rotate these devices.

In order to reduce friction between the support roller and the roller of the cylindrical rotating body and to make the rotation smooth, lubricating oil is supplied to the contact surface between the two and an oil film is always formed on the roller surface. It is necessary. In one aspect thereof, an oil tank having an open upper surface is installed below the support roller so that the lower portion of the support roller is always immersed in the lubricating oil contained in this oil tank.

[0004]

According to this aspect, the rotation of the support roller causes the lubricating oil to be automatically pumped up from the oil tank and applied to the roller of the cylindrical rotating body.
One of the problems with this embodiment is that the support roller pumps up an amount of lubricating oil in excess of the amount required for lubrication and applies it to the roller of the cylindrical rotating body. As a result, an excessive amount of lubricating oil is always attached to the roller of the cylindrical rotating body, and the lubricating oil drops from the roller and contaminates the surroundings. Accordingly, the present invention is intended to provide a method capable of automatically applying a lubricating oil to a roller of a cylindrical rotating body and reducing oil contamination.

[0005]

According to the present invention, a cylindrical rotating body having a cylindrical main body and a roller arranged coaxially with the cylindrical main body is installed horizontally or at an angle close thereto. Then, in the method of supporting and rotating the roller portion at the lower part thereof by a plurality of supporting rollers that rotate while a part of the roller portion is immersed in the lubricating oil housed in the oil tank, the thickness of the oil film on the supporting roller is By attaching the regulating oil removing material to the support roller, it is possible to prevent excessive amount of lubricating oil from adhering to the roller of the cylindrical rotating body and contaminating the surroundings.

The present invention will be described in detail below.
The present invention, such as a drum dryer or a drum granulator, is provided with an annular roller coaxially with the cylindrical main body at several places on the outer periphery in the lengthwise direction, and the roller is supported by a support roller. It can be widely applied to a rotating type device. In the present invention, an oil removing material is attached to the supporting roller in order to regulate the thickness of the oil film on the supporting roller by removing the excessive amount of the lubricating oil drawn from the oil tank by the rotation of the supporting roller. The degreaser may be a flexible pad that is in loose contact with the support roller,
A roller (oil removing roller) that rotates by following the supporting roller is preferable. The oil removing roller is attached to the side where the supporting roller comes out of the lubricating oil in the oil tank. The thickness of the oil film on the support roller can be arbitrarily controlled by appropriately adjusting the pressing force of the oil removing roller on the support roller. The oil removing roller is attached to the support roller above the opening surface of the oil tank so that the lubricating oil removed by the oil removing roller naturally falls into the oil tank. Preferably, the oil removing roller is partially provided with a cover preferably covering the side of the oil removing roller so as to prevent the oil removed by the oil removing roller from scattering around.

According to one aspect of the present invention, an oil removing roller which is driven by the roller and rotates is also attached to the side surface of the roller of the cylindrical rotary member. This makes it possible to prevent the lubricating oil applied from the support roller to the roller surface of the cylindrical rotary member from moving to the side surface of the roller and staying there, and eventually dripping and contaminating the surroundings.

The present invention will be described in more detail with reference to the drawings. FIG. 1 is an example of an embodiment of the present invention.
Reference numeral 1 is a cylindrical main body, 2 is an annular roller mounted coaxially with the outer circumference of the cylindrical main body, and 3 is a supporting roller for supporting a cylindrical rotating body. Usually, some of the support rollers are drive rollers and others are driven rollers. Reference numeral 4 denotes an oil tank containing lubricating oil, and the lower portion of the support roller 3 is immersed in the lubricating oil in the oil tank. Reference numeral 5 is an oil removing roller for removing excess lubricating oil from the support roller 3. The mechanism for adjusting the pressing force of the oil removing roller is omitted. Reference numeral 6 denotes an oil removing roller that comes into contact with the side surface of the roller of the cylindrical rotating body and rotates following this.
As shown, this roller is preferably mounted at the bottom of the roller of the cylindrical rotating body so that the removed oil falls into the oil tank without splashing. Reference numeral 7 is a cover for partially covering the oil removing roller 5 attached to the supporting roller to prevent scattering of the removed oil.

[0009]

According to the present invention, the surroundings are prevented from being contaminated by the scattering of the lubricating oil, and the consumption of the lubricating oil is reduced.
