Table type high-speed refrigerated centrifuge based on alternating-current variable-frequency motor driving and method thereof

Abstract

The invention discloses a table type high-speed refrigerated centrifuge based on alternating-current variable-frequency motor driving and a method thereof, and belongs to the technical field of high-speed refrigerated centrifuges. The table type high-speed refrigerated centrifuge comprises an outer box body, wherein a machine base is arranged above the outer box body, a control panel is arranged on the machine base, an inner groove is formed inside the outer box body, a centrifugal device is arranged inside the inner groove, a cover plate is arranged on the upper end surface of the outer box body, and a gland device is arranged on the cover plate. According to the table type high-speed refrigerated centrifuge based on alternating-current variable-frequency motor driving and the method thereof, the explosion-proof problem is avoided, conveyed materials are guided in along the inner wall through an arc-shaped flow guide plate, splashing and explosion caused by direct discharging are prevented, internal objects are prevented from being spilled out in the whole centrifugal process, the centrifugal efficiency is improved, the scraping efficiency is improved, the materials are convenient to clean, residual materials are prevented from blocking the inner wall of an inner barrel, the residual material collecting efficiency is improved, high-rotating-speed and high-voltage operation is achieved, energy is effectively saved, and the table type high-speed refrigerated centrifuge can be suitable for centrifugation at different rotating speeds according to needs.

Description

technical field [0001] The invention relates to the technical field of high-speed refrigerated centrifuges, in particular to a desktop high-speed refrigerated centrifuge driven by an AC variable frequency motor and a method thereof. Background technique [0002] Centrifuges, also known as precipitators, include separation centrifuges for quickly separating suspended substances in liquids, large preparative centrifuges for concentrating and purifying particles, and low-speed analytical centrifuges for experimental analysis. Although there are different types of centrifuges, the functions can be considered as separation, concentration, purification and analysis. The development of the centrifuge is reflected in the continuous improvement of the structure and the improvement of the centrifugation method. The improvement of the structure is first reflected in the increase of the speed. The ultra-high-speed centrifuge developed from only a few tens of revolutions at the beginnin...
