A chamber for centrifugal separation includes a chamber body having an upper opening and a lower opening opposite to the upper opening, an upper cover having an upper injection port and mounted on a chamber main body to cover the upper opening, a lower cover having a lower injection port and mounted on the chamber body to cover the lower opening, a receiving space provided in the chamber main body, and including a first receiving part communicating with the lower injection port and an extracting part extending upward from the first receiving part and having a section area smaller than a sectional area of the first receiving part, and a remaining liquid receiving space provided in the chamber main body to receive a material flowing over the receiving space, as the material is injected into the receiving space from the lower injection port.

A centrifuge basket includes a support basket with a support base and a support wall circumferentially extending around a basket axis of the centrifuge basket. The support base and the support wall have a plurality of through openings with passage areas of at most 500 square millimeters, and a filter fabric which is arranged in the support basket and covers the support base and the support wall on the inside. The filter fabric includes, viewed in a cross-section through the centrifuge basket, a plurality of regions distributed over a circumference which are formed radially inwards with respect to a circular basic shape of the filter fabric.

A grinding water treatment device for eyeglasses lens processing includes a centrifugal separator, a scraping unit, an opening, and a filter. The centrifugal separator includes a dehydration tank into which grinding water used in a processing device of an eyeglasses lens is introduced, and separates the grinding water into water and processing chips by rotation of the dehydration tank. The scraping unit scrapes out the processing chips accumulated on a side wall inside the dehydration tank. The opening is provided in the dehydration tank and through which the processing chips scraped out by the scraping unit are ejected to an outside of the dehydration tank. The filter is provided in an outer region of the opening, and through which the water separated from the grinding water by rotation of the dehydration tank passes to allow the processing chips to be present inside the dehydration tank.

Provided is a centrifuge including: a rotary chamber configured to rotate so that centrifugal force acts on a substance contained in the rotary chamber; a storage unit configured to store a certain component separated from the substance in the rotary chamber by the centrifugal force according to rotation of the rotary chamber; and a filter located between the storage unit and the rotary chamber and through which the certain component, which is separated from the substance in the rotary chamber by the centrifugal force according to the rotation of the rotary chamber, passes to be stored in the storage unit. The storage unit includes a return prevention unit configured to prevent the certain component, which is separated from the substance in the rotary chamber by the centrifugal force according to the rotation of the rotary chamber and is stored in the storage unit, from returning from the storage unit to the rotary chamber. The present disclosure has an effect of easily separating a certain component sought to be separated.

A method for fixing a metal sheet serving as a filter element or the like to the inner peripheral wall of a filter device is disclosed. The metal sheet is arranged in a round shape, optionally with overlapping axial edge regions, on the inner peripheral wall of the housing of the filter device and is pressed against the peripheral wall of the housing with the aid of an expansion device. The disclosure further relates to a filter device produced in this way and to the expansion device used to carry out such a method.
