Abstract

The invention relates to devices for concentrating suspensions, in particular centrifuges. It can be used in the microbiological, medical, food and other sectors of the industry and is aimed at increasing productivity. The suspension to be processed through the window 10 of the chamber 11 and the channel 9 is fed into the working chamber 8. Large solid particles fill the periphery of the chamber 8 and channel 9. The sediment at the periphery of chamber 8 is a loose permeable mass, since the direction of fluid flow in the working chamber 8 it is directed against centrifugal forces, which prevents the draft from condensing, and the radially mounted permeable partitions 7 hold the deposit, allowing swirling fluid flows. In this way, a natural prefilter is formed which is not eroded by swirling liquid flows. Next, the suspension, the passage through the precipitate formed, is cleared of the smallest particles and, due to the difference in the levels of D ₁ and D _{2, the} liquid is forced through the filter element into the chamber 5. 1 sludge.

Description

the action of centrifugal forces, which prevents the draft from compacted, and the radially mounted permeable partitions 7 hold the deposit, passing swirling fluid flows. In this way a natural pre-filter is formed which is not

eroded by swirling streams of fluid. Then the suspension, the passage through the precipitate formed, is purified from the smallest particles and due to the difference in the levels 1), and the liquid is pressed through the filter element into the chamber 5. 1 sludge.

The invention relates to devices for concentrating suspensions, in particular centrifuges, the separating element of which is a membrane filter, and can be used in microbiological, medical, food and other industries.

thinking

The aim of the invention is to increase productivity.

The drawing shows the proposed centrifuge, longitudinal section.

The centrifuge contains a rotor, formed by two large bases of cone-shaped plates 1 and 2 facing one another and facing each other. The plate 1 is mounted for movement in a vertical plane. A filter element is attached to the bottom plate 2, which is a perforated shell 3 with a lid 4. The filter element is attached to the plate 2 to form a chamber 5 for collecting the filtrate. A conical nozzle 6 is attached to the lid 4 with permeable partitions 7 fixed on its inner surface. The plate 2, the conic head 6 and the filtering element form the working chamber 8, and the plate 1 and the conic nozzle 6 - channel 9 for supplying the suspension to the working chamber 8. Plate 1 has a window 10 for introducing the suspension into the chamber 11 formed by the plate 1 and the lid 4 of the filter element. In the plate 2, windows 12 are made to remove the filtrate from the chamber 5.

The centrifuge operates as follows.

The suspension to be processed through the window 10 of the chamber 11 and the channel 9 is fed into the working chamber &. Large solid particles fill the periphery of chamber 8 and channel 9. The precipitate at the periphery of chamber 8 is a loose permeable mass, since the direction of flow of fluid in the working chamber

8 is directed against the centrifugal forces, which prevents the draft from condensing, and the radially mounted permeable partitions 7 hold the deposit, passing swirling fluid flows. In this way, a natural prefilter is formed which is not eroded by swirling liquid flows. Next, the suspension, the passage through the precipitate formed, is cleared of the smallest particles and due to the difference in the levels of L.f and the liquid is forced through the filter element into the chamber 5 and through the windows 12 is removed from the rotor. After the working chamber 8 is filled with sediment, the rotor opens due to the axial movement of the plate 1 and the sediment is ejected into the receiving device. Then the plates 1 and 2 are closed and the process is repeated.

The use of the proposed device ensures a longer filter operation due to the use of pre-aggregation of fine particles and thereby an increase in centrifuge productivity.
