Sedimentation device for raw ceramic powder particle testing

Abstract

The invention is applicable to the technical field of ceramic production, and provides a sedimentation device for raw ceramic powder particle testing. The device comprises a synchronous lifting platform, a detecting mechanism, an electromagnetic lifting device and a constant-temperature assembly, wherein the synchronous lifting platform is fixedly connected to the detecting mechanism; the detecting mechanism is positioned on the outer surface of the upper end of the synchronous lifting platform; the synchronous lifting platform controls a lamp, a Fourier lens and a photoelectric receiver to synchronously lift by reciprocating; the photoelectric receiver is used for converting an optical signal into an electric signal and transmitting to an analyzing module; the analyzing module is used forgenerating a ceramic raw material particle size report based on the data; the electromagnetic device can work stably; the synchronous lifting platform is stable to reciprocate; the controller moves along a guider rail based on a linear motor controlled through a preset program; a constant-temperature water layer wraps a sample container, so that the sampler container is kept in constant temperature, and the temperature of test liquid sample is kept constant, and as a result, error is reduced.

Description

Technical field [0001] The invention belongs to the technical field of ceramic production, and particularly relates to a sedimentation device for testing ceramic raw material powder particles.
