Centrifugal machine for experimental detection

Abstract

The centrifugal machine for experimental detection comprises a box body and a box cover, the box cover is hinged to one side edge of the top end of the box body, a vertical centrifuge is fixedly embedded in the position, at the bottom end of a centrifugal cavity, of the box body, a rotating disc is fixedly connected to a rotating shaft of the centrifuge, and a groove is formed in the middle of the top end of the rotating disc; a plurality of limiting grooves are formed in the upper end of the inner side wall of the groove of the rotating disc, a centrifugal plate is fixedly clamped to the top end of the rotating disc, and a plurality of limiting blocks are fixedly connected to the upper ends of the peripheral side walls of the centrifugal plate. The device is ingenious in structural design, and through the limiting groove and the limiting block, the centrifugal plate can be clamped by the rotating disc conveniently; by inclining the centrifugal groove, the centrifugal tube can be stabilized, so that the centrifugal effect of centrifugal substances is guaranteed; the centrifugal plate is conveniently fixed again through the arc-shaped limiting ring, and meanwhile, the centrifugal plate can achieve rotary clamping of the arc-shaped limiting ring; and the limiting rods are inserted into the arc-shaped limiting holes, so that rotation of the arc-shaped limiting rings is facilitated.

Description

technical field [0001] The invention relates to the field of laboratory testing tools, in particular to a centrifuge for experimental testing. Background technique [0002] A centrifuge is a machine that uses centrifugal force to accelerate the centrifugation of different materials that need to be centrifuged. The centrifuge is mainly used to separate the solid particles in the suspension from the liquid, or to separate two liquids with different densities and immiscible liquids in the emulsion (such as centrifuging cream from milk); it can also be used to remove Liquid in wet solids, such as drying wet clothes with a washing machine; special ultra-speed tube centrifuges can also centrifuge gas mixtures of different densities; using the characteristics of different sedimentation speeds of solid particles of different densities or particle sizes in liquids, some sedimentation Centrifuges can also classify solid particles by density or size. [0003] Centrifuges are widely u...
