The cleaning liquid that has entered the machine is once guided to the lower portion of the separation plate layer by the guide cylinder, and then flows while moving up the gap between the rotating separation plates toward the inner diameter side, and cleans and removes attached sludge.

の液面半径The sludge having a high specific gravity moves radially outward due to centrifugal force, accumulates in the separation chamber, and is discharged outside the machine by opening the valve cylinder after the completion of the washing operation. On the other hand, the cleaning liquid from which sludge has been removed enters the impeller chamber through the light liquid passage above the separation plate layer and is pumped out of the machine by the action of the centripetal pump type impeller. At this time, the discharge pressure of the impeller is determined by the following equation Is done. P = γ / 2g × ω 2 (r 1 2 -r 2 2) ( Saburo Kamei al., Calculated to the theory of chemical-mechanical, industry books, p4

上昇して、それだけ循環量も増加する。As can be seen from FIG. 1, the discharge side of the impeller communicates with the feed pipe via the return pipe and the circulation pipe. Circulate in the mouth. At this time, the valve that enters the cleaning liquid tank in the return line is closed. Therefore, if the pressure in the cleaning liquid tank is increased to appropriately increase the amount of the cleaning liquid fed into the centrifugal separator from the feed pipe, the liquid level r in the impeller chamber can be increased.
2 also moves to the inner diameter side, the discharge pressure P determined by the above equation also increases, and the circulation amount increases accordingly.

環して、遠心分離機内部を洗浄する。When the discharge pressure P of the impeller rises and the circulation amount of the cleaning liquid reaches a predetermined amount, the valve of the feed pipe is closed.
As a result, the washing liquid sent into the centrifugal separator is impeller → light liquid outlet →
Return line → Circulation line → Feed line → Stock solution supply port → Guide tube →
The inside of the centrifuge is washed by circulating through the separation plate layer → light liquid passage → impeller chamber → impeller path.

流出する以外は、同じ作用である。At this time, if the pressure of the cleaning liquid tank is increased, the discharge pressure of the impeller, which balances with the pressure, is also increased.
The circulation flow rate of the cleaning liquid can be increased. The above description of the operation is for the case of claim 1, but for claim 2
In the case of (1), the operation is the same except that the washing liquid flows out of the light liquid outlet and the heavy liquid outlet.
