Continuous power/liquid mixing apparatus

Abstract

A continuous powder-liquid mixer is composed of a rotary mixing disc for uniform mixing between powder and liquid, a drive motor, a magnetic coupling unit between said mixing disc and the rotating shaft of drive motor, a mixing chamber without sealing structure for the rotary axle of mixing disc, an overflow cone to make the liquid flow downward along its inner surface to form a overflow film, a powder supplying cylinder with an opening aligning to said overflow cone, a dispersing cone in the center on upper surface of mixing disc, and a liquid nozzle pointing to the center of said dispersingcone.

Description

technical field [0001] The present invention relates to a device for continuously mixing powders and liquids, and in particular to a powder / liquid continuous mixing device: in a rotating mixing disc used to obtain a uniform mixed fluid of powders and liquids, driven by a motor The coupling of the shaft is magnetic coupling, omitting the sealing structure of the rotating shaft part of the rotating mixing disc, and it can be made into a completely leak-free structure that completely separates the mixing chamber from the driving part, so it can be applied to special solvents that were difficult to handle in the past, and can It prevents the powder from reacting with the solvent and adhering to the inflow surface of the solvent or the outer periphery of the powder drop port, etc., and enables optimal continuous mixing of powder and liquid even with a small amount. Background technique [0002] In the past, in the food, chemical, pharmaceutical, plastic, electronics, ceramics, ma...

AI Technical Summary

Problems solved by technology

[0012] In the above-mentioned conventional powder and liquid continuous mixing devices, since the rotating mixing disk for discharging the uniform mixed fluid of powder and liquid is combined with the rotating shaft of the driving motor, in order to prevent the clogging of the powder or liquid leakage, the shaft seal is made into a complicated and intricate structure, or various special parts with excellent resistance are used in the shaft seal part, so the structure of the device is complicated and the manufacturing cost is increased, and there is also a need for frequent repairs. Difficulties such as maintenance work

Especially when a special solvent with the property of dissolving it is used as a mixed liquid for the shaft seal part, it is difficult to continuously mix the powder and the liquid due to leakage of the liquid.

In addition, in the case where the reaction between the powder and the solvent is significant, not only the powder will adhere to the inflow surface of the solvent and the outer periphery of the powder drop port, etc., hindering the normal continuous mixing of the powder and the liquid, but also It is also difficult to carry out precise continuous mixing of powder and liquid
