摘要： A drum centrifuge has a housing, a drum in the housing, an axially extending outer foraminous side wall in the interior of the drum forming an outer chamber, and a transversely extending foraminous end wall in the drum forming a bypass chamber radially inward of the outer chamber. A suspension is fed to the interior of the drum while same is rotating so that the suspension is thrown centrifugally against the outer wall and separates into a radially outer body of filter cake having an inner surface and a radially inner body of liquid sitting on the inner surface. A drainage chamber is formed at the end wall and a drain passage extends between the drainage chamber and the outer chamber while a bypass passage extends between the drain chamber and the bypass chamber. A float valve in the passage is radially displaceable when a liquid level in the passage rises radially inward above a predetermined level between a radially outer position blocking flow through the passage and a radially inner position permitting flow through the passage. A dip tube is radially displaceable in the drain chamber between a radially outer position maintaining the liquid level in the drainage chamber and in the passage radially outward of and below the predetermined level and a radially inner position allowing the liquid level in the drainage chamber and passage to rise radially inward above the predetermined level and thereby open the float valve.
摘要翻译：鼓式离心机具有壳体，壳体中的鼓，在鼓的内部中的轴向延伸的外部有孔的侧壁，形成外部室，并且滚筒中的横向延伸的多孔端壁形成径向向外的外侧的旁路室房间。将悬浮液供给到滚筒的内部，同时旋转，使得悬浮液离心地抛靠在外壁上并分离成具有内表面和位于内部的液体的径向内部体的滤饼的径向外部主体表面。排水室形成在端壁处，排水通道在排水室和外室之间延伸，而旁路通道在排水室和旁通室之间延伸。当通道中的液位在通过通道的径向外部位置阻止流动的径向向内高于预定水平面的径向向内流动通过通道的径向内部位置时，通道中的浮阀可径向移动。汲取管可以在排水室中在径向外部位置之间径向移动，该径向外部位置保持排水室中的液面和径向向外和低于预定水平的通道和径向内部位置，允许排液室中的液面和通道从而径向向内升高到预定水平以上，从而打开浮阀。

摘要： The invention relates to a method for recovering spent machining slurries and to an apparatus for carrying out the method. The spent machining slurry that contains a machining medium, a carrier fluid for the machining medium, material stemming from the machined articles, particles stemming from the machining tools and optionally additives, is recovered by centrifugation in the undiluted state, thereby allowing an especially effective recovery according to materials and without much effort. The used apparatus is characterized in that it comprises a centrifuge having a suspended centrifugal drum or a stationary centrifuge having a floating centrifuging drum.

摘要： A centrifuge having a drum rotatable in a predetermined direction about a drum axis has a cleaning device with a cleaning shaft extending generally parallel to the drum axis into the drum along a shaft axis. A pair of elongated slat-shaped cutters have inner ends fixed on the shaft, outer ends, and project radially outward of the shaft axis from the shaft. The inner ends are separated by a relatively narrow space, and the cutters diverge from their inner ends toward their outer ends. The shaft can be moved such that the cutters are displaced between a standby position offset from the drum and a cleaning position closely juxtaposed therewith. A cleaning liquid is fed to each cutter such that it flows along the cutters.

摘要： A filter apparatus has a drum rotatable about an axis and having a foraminous outer wall with an inner surface, a support screen lying directly on the inner surface, a filter mesh lying directly on the support screen, and a protective screen lying on the filter mesh and holding same against the support screen. The support screen and mesh are held in place by a retaining seal having at least two lips defining at least one recess snugly receiving the edges of the support screen and mesh with one the lips between the support screen and the drum inner surface. The protective screen lies on the other lip of the seal and presses the seal against the surface of the drum while clamping the edges in the recess.

摘要： A centrifuge has a generlly stationary and closed housing, a drum rotatable in the housing about a drum axis and having an end wall and an outer drum wall, a blade extending generally axially in the housing generally parallel to the drum wall, and a blade holder having an inner end carrying the blade and an outer end projecting through the housing end wall out of the housing. Seals snugly engaged between the outer end and the housing hermetically seal the housing around the holder and a guide fixed on the end wall supports the outer holder end on the housing for sliding movement of the holder and blade on the housing in an adjustment direction generally radial of the drum axis. An actuator engaged between the housing and the outer holder end displaces the holder and blade in the adjustment direction relative to the housing.
