Claims

[Claims for Utility Model Registration] (1) A basket having a large number of permeable holes in its peripheral wall, and a cylindrical filter fitted into the inner periphery of the peripheral wall of the basket and fixed to the basket; A scraping blade is provided so as to be able to enter the basket up to an entry limit position set near the filter, and the scraping blade scrapes solid matter formed on the inner periphery of the filter. In a centrifugal separator equipped with a solid matter scraping device, residual solid matter suction and discharge is performed to suck out solid matter remaining on the inner periphery of the filter and discharge it to the outside of the basket after the scraping by the scraping blade has been completed. What is claimed is: 1. A centrifugal separator comprising: a device, wherein the filter has a rigidity capable of withstanding the suction force of the residual solid matter suction and discharge device. (2) The filter has a structure in which a plurality of perforated plates made of metal plates or wire mesh having a large number of holes are laminated and integrated until a predetermined thickness is obtained, and the thickness of the filter is equal to the thickness of the suction plate. The centrifugal separator according to claim 1, wherein the centrifugal separator is sized to have sufficient rigidity to withstand the force. (3) Claim 1, wherein the filter is made of porous sintered metal having a thickness that can withstand the suction force.
The centrifuge described in . (4) The residual solid matter suction and discharge device is characterized in that it includes a residual solid matter suction port that is movable between a suction position close to the filter and a retreat position away from the filter. The centrifugal separator according to any one of claims 1 to 3. (5) Claim characterized in that the residual solid matter suction port is attached to a scraping blade of the solid matter scraping device, and is displaced between the suction position and the retreat position together with the scraping blade. 4. The centrifugal separator according to 4.
