Problems solved by technology

Nevertheless, desktop centrifuges still have relatively fatal defects: (1) Solids cannot be cleaned online: that is, solids are washed while the rotor is rotating, which cannot simulate the actual situation in production and provide necessary centrifugation operation data for production in advance; (2) Online feeding is not possible: that is, feeding is carried out while the rotor is rotating; (3) A precise trimming barrel is required for centrifugation, and a single sample cannot be centrifuged; (4) The loading capacity of the barrel is limited and cannot well meet various needs
However, the existing various centrifuges or solid-liquid separators have complex structures, and it is difficult to fix and take out the centrifuge drum. At the same time, the cleaning of the centrifuge is also time-consuming and laborious, and the manufacturing process is complicated, expensive, and the repair and maintenance costs are high. Various defects or disadvantages, can not better meet the needs of the complete separation of solid-liquid mixture in the laboratory test and pilot test

Abstract

The invention discloses a directly-driven centrifugal separation device. The device comprises a motor rotor integrated with a centrifugal rotating disc to form a whole body and a centrifugal rotatingdrum or a centrifugal rotor used as an independent component; or the device comprises a motor rotor integrated with a centrifugal rotating disc to form a whole body and a motor stator; the position ofa motor air gap port led to one side of a ring-shaped groove is higher than the inner surface of the bottom of the ring-shaped groove with a liquid discharging opening; a gap connected with the motorair gap is sealed in any position led to one side of the ring-shaped groove; a target material is isolated from the motor air gap by sealing the gap. The directly-driven centrifugal separation devicehas the advantages that the motor rotor of the device and the centrifugal rotating drum or the centrifugal rotor can switch between a locked state and an unlocked state; all the parts of the device are convenient to manufacture; the whole device is convenient to assemble; the device is high in safety, quiet and stable in operation and easy to maintain, clean and check, and can overcome various defects or disadvantages of the existing solid-liquid separation device.

Description

[0001] This application is a divisional application with an application date of March 23, 2015, application number CN201510128476.8, application publication number CN105251624A, and the title of the invention is "a direct-drive centrifugal separation device". technical field [0002] The invention relates to a direct-drive centrifugal separation device and its use method, in particular to a small-scale solid-liquid mixture centrifugal separation device and its use method, which can be used in laboratories to remove gram-level to kilogram-level solids from solid-liquid mixtures. Completely separate and clean the equipment thoroughly. Background technique [0003] In the laboratory test and pilot test research and industrial production process, we often encounter the need to completely separate the solid-liquid mixture and wash the solid to obtain a solid or liquid that meets the requirements. The solid-liquid separation equipment often used in industrial production is a varie...
