上記従来技術は遠心薄膜蒸発機の下部軸受において、下部軸受の潤滑液の供給 を缶外部から行なっており、そのため、ポンプ等を有する下部軸受潤滑液供給装 置が必要であった。 The above conventional technology is used to supply lubricating fluid to the lower bearing of a centrifugal thin film evaporator. This is done from outside the can, so the lower bearing lubricant supply system, which includes a pump, etc. It was necessary to

上記目的を達成するために、原料処理液を軸受部に導く樋を回転翼の先端に設 け、軸受部に集まった原料処理液を軸受の摺動部に圧入させるため上段ねじスリ ーブを設け、更に、潤滑液としての役目が終わった原料処理液が軸受下部に溜る ので、それを缶外に排出させるため、下段ねじスリーブを設けたものである。 In order to achieve the above purpose, a gutter is installed at the tip of the rotor blade to guide the raw material processing liquid to the bearing. In order to press the raw material processing liquid that has collected in the bearing into the sliding part of the bearing, the upper screw thread is installed. In addition, the raw material processing liquid that has finished its role as a lubricant collects at the bottom of the bearing. Therefore, a lower threaded sleeve was installed to allow this to be discharged outside the can.

原料処理液は回転翼によって胴壁面に押し付けられながら、薄い膜状となって 降下する。その原料処理液を回転翼先端に設けた樋で軸受に流し込む。この樋の 取付角度は原料処理液の粘度(流動性)によって、流れ勾配は任意に決定する。 軸受部に流れ込んだ原料処理液は、上段ねじスリーブによって僅かな隙間を持た せた軸受の摺動部へ圧入され、潤滑液の役目をする。摺動部から出た原料処理液 は、そのままにしておくと軸受下部に溜るので、この排出用として設けた下段ね じスリーブで缶外へ押し出される。また、原料処理液の粘度が低く、自然状態で 流動するような物性の場合は、下段ねじスリーブを逆方向に切り、液を上側に押 し上げ気味にすることで、摺動部の膜切れ防止をさせることも可能となる。 The raw material processing liquid is pressed against the shell wall surface by the rotary blades, forming a thin film. Descend. The raw material treatment liquid is poured into the bearing through a gutter installed at the tip of the rotor blade. This gutter The mounting angle is determined depending on the viscosity (fluidity) of the raw material processing liquid, and the flow gradient is arbitrarily determined. The raw material processing liquid that has flowed into the bearing has a small gap between it and the upper threaded sleeve. It is press-fitted into the sliding part of the bearing and acts as a lubricant. Raw material processing liquid coming out of the sliding part If you leave it as is, it will accumulate at the bottom of the bearing, so please use the lower tier provided to drain it. It is pushed out of the can by the same sleeve. In addition, the viscosity of the raw material processing liquid is low, and it If the property is fluid, cut the lower threaded sleeve in the opposite direction and push the liquid upward. By slightly raising the surface, it is also possible to prevent the film from breaking on the sliding part.

以下、本考案による一実施例を図により説明する。本体1内に供給された原料 処理液2は、胴壁面を降下しながら一部が回転翼4の先端に設けられた勾配を持 つ樋5に流れ込む。樋5の一端は下部軸受箱6の近くにあるため、原料処理液2 は自然に軸に設けた上段ねじスリーブ7に入っていく。上段ねじスリーブ7には 複数条のねじが切ってあり、回転することによりねじ溝にある原料処理液2を下 方へ押し下げる。押し下げられた原料処理液2は、軸受9,10の摺動部の僅か な隙間を通過することにより潤滑液の役目を果たす。軸受9,10摺動部を通過 した原料処理液2は、その後下段ねじスリーブ8によって本体1外へ押され排出 される。これによって、下部軸受6への外部からの潤滑液供給装置が不要となる 。なお、摺動部を通過した原料処理液2は外部へ排出されるので、本体1の原料 処理液2内へ下部軸受材のカーボン等が混入することはない。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Raw materials supplied into main body 1 The processing liquid 2 flows down the barrel wall surface, with a portion having a slope provided at the tip of the rotor blade 4. Flows into trough 5. Since one end of the gutter 5 is near the lower bearing box 6, the raw material processing liquid 2 naturally enters the upper threaded sleeve 7 provided on the shaft. The upper threaded sleeve 7 has Multiple threads are cut, and by rotating, the raw material processing liquid 2 in the thread groove is lowered. push down toward The pressed-down raw material processing liquid 2 is applied to a small portion of the sliding parts of the bearings 9 and 10. It acts as a lubricant by passing through the gaps. Passing through the sliding parts of bearings 9 and 10 The treated raw material processing liquid 2 is then pushed out of the main body 1 by the lower threaded sleeve 8 and discharged. be done. This eliminates the need for an external lubricant supply device to the lower bearing 6. . In addition, since the raw material processing liquid 2 that has passed through the sliding part is discharged to the outside, the raw material in the main body 1 Carbon and the like from the lower bearing material will not be mixed into the processing liquid 2.

本考案によれば、原料処理液を下部軸受に自動的に取り込むため、従来必要で あった下部軸受の潤滑液供給装置が不要となり、また、原料処理液内へ下部軸受 材のカーボンの混入が防げる効果もある。 According to the present invention, the raw material processing liquid is automatically taken into the lower bearing, which is not necessary in the past. The lubricating fluid supply device for the lower bearing that was previously used is no longer required, and the lower bearing can be fed into the raw material processing fluid. It also has the effect of preventing carbon from entering the material.
