Direct-driven centrifugal separation equipment

Abstract

The invention discloses direct-driven centrifugal separation equipment. The equipment is characterized by comprising one or more components of a centrifugal rotary table or a centrifugal rotary barrel (A), a centrifugal rotary drum or a centrifugal rotor (B), a centrifugal liquid collection cavity (C) and a driving system (D). The direct-driven centrifugal separation equipment has the advantages that the size of the centrifugal rotary drum can be changed freely according to needs, and the centrifugal rotary drum can be placed in and taken out easily and conveniently; the centrifugal liquid collection cavity serving as a system main body is integrally manufactured through the integral forming technology, the manufacturing process is simple, and the cost is low; the whole centrifugal system is simple, practical, capable of saving energy, environmentally friendly and convenient to apply and popularize.

Description

technical field [0001] The invention relates to a direct-drive centrifugal separation device, which belongs to the field of centrifuges. Background technique [0002] 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 variety of centrifuges, especially three-legged centrifuges. However, at present, the equipment obtained from the miniaturization and improvement of the centrifuge for industrial production is still too bulky, the noise and vibration are too large, and the centrifugal drum cannot be changed according to the needs or is not easy to replace, so it is not suitable for small laboratory tests and pilot test requirements. [0003] In laboratory research, the equipment we can choose is mainly a combination of...

AI Technical Summary

Problems solved by technology

Nevertheless, desktop centrifuges still have relatively fatal defects: (1) cannot clean solids online: that is, solids are washed while the rotor is rotating, which cannot simulate the actual situation in production and provide necessary centrifuge operation data for production in advance; (2) cannot Online feeding: that is, feeding is carried out when the rotor is rotating; (3) It must have a precise trim barrel before centrifugation can be performed, and a single sample cannot be centrifuged; (4) The loading capacity of the barrel is limited to a certain extent and cannot well meet various needs

In order to remove these fatal defects of the desktop centrifuge, people have equipped its centrifugal rotor with a cleaning liquid distributor such as publication number JP142691 / 2002 or a continuous feeding device such as the publication number CN2030910 (application number CN87214144), which has caused the structure of the desktop centrifuge to be further complicated and Expensive, not conducive to promotion and use

Even after the above improvements, the defect (3) still exists

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
