この種の装置として関連するものには例えば特開昭５７
−１２４１９４号が挙げられる。Conventionally, for example, in a centrifugal thin-film evaporator, lubricating liquid for the can bearing is supplied from a tank to the can bearing through piping by a pump, enters from the bottom of the bearing, passes through the bearing, exits from the top and enters the tank. It was returning, lubricating, and circulating. In addition,
Related devices of this type include, for example, Japanese Unexamined Patent Publication No. 57

受内に溜って潤滑不良を起こすという欠点があった。[Problems to be Solved by the Invention] In the above-mentioned conventional technology, there is a possibility that the processing liquid in the can always invades the bearing part in the can, and if the processing liquid is heavier than the lubricating liquid, it accumulates in the bearing and causes poor lubrication. It had the disadvantage of causing
本発明は、缶内の処理液が軸受内に溜るのを防止して潤
滑不良が起こらないようにすることを目的とする。An object of the present invention is to prevent the processing liquid in the can from accumulating in the bearing, thereby preventing poor lubrication.
［課題を解決するための手段］
上記目的を達成するために、タンクから供給される潤滑
液が軸受の上側から入り下側から取出されるように配管
する。また、タンク内には隔壁を設けて、軸受へ供給す
る室と軸受から戻る室とを分離させたものである。[Means for Solving the Problems] In order to achieve the above object, piping is provided so that lubricating fluid supplied from a tank enters the bearing from the upper side and is taken out from the lower side. Furthermore, a partition wall is provided in the tank to separate a chamber for supplying to the bearing from a chamber for returning from the bearing.

ことはない。When the processing liquid inside the can enters the bearing inside the can, the processing liquid passes through the bearing together with the supplied lubricating liquid, reaches the bottom of the bearing inside the can, and is discharged from the lubricating liquid outlet, so that it does not accumulate inside the bearing. There is no. Furthermore, the processing liquid that has entered the tank through the piping is separated by the partition wall inside the tank, so it will not be circulated again.
〔実 施 例１ 第１図及び第２図に本発明による一実施例を示す。[Implementation example 1] An embodiment according to the present invention is shown in FIGS. 1 and 2.

アーム１７からなっている。The lubricating system for the bearing inside the can consists of tank 1, pump 2, and flow meter 3.
, piping 4, sight glass 5, drain valve 6, bulkhead 16
and a pressure equalizing nozzle 7, and the can bearing section is composed of a rotor 14, a blade 15, a shaft 12, a housing 11, an oil seal 13, a bearing lO1 lubricant port 8, a lubricant outlet 9, and an arm 17.

排出される。The lubricating liquid is guided from the tank 1 by the pump 2 through the flow meter 3 and piping 4 to the lubricating liquid port 8, flows from the upper side of the housing 11 to the lower side, passes through the bearing 10, reaches the lubricating liquid outlet 9, and reaches the lubricating liquid outlet 9 through the sight glass. 5 and return to tank 1. The processing liquid in the can passes between the housing 11 and the shaft 12 and enters the bearing 10 through the gap between the oil seals 13, but flows together with the lubricating liquid and is guided to the lubricating liquid outlet 9 and returns to the tank l. Since the tank 1 has a partition wall 16, this processing liquid is discharged to the outside of the system through the drain valve 6 without being mixed with fresh lubricating liquid.
装置本体が真空で運転される場合には、均圧ノズル７を
真空発生装置と接続することにより、同様に運転が可能
となる。When the main body of the apparatus is operated in a vacuum, the same operation is possible by connecting the pressure equalizing nozzle 7 to a vacuum generator.
本実施例によれば、缶内の処理液を缶内軸受内に溜める
ことなく、取出して系外へ排出することが可能である。According to this embodiment, it is possible to take out the processing liquid in the can and discharge it to the outside of the system without accumulating it in the bearing in the can.
