Centrifugal negative-pressure powder feeding and mixing apparatus

Abstract

The invention relates to the technical field of reaction kettles, and particularly relates to centrifugal negative-pressure powder feeding and mixing apparatus. The mixing apparatus comprises a shell;the shell is provided with a first rotating shaft, a second rotating shaft, blade stirring assemblies, a frame type wall scraping assembly, an emulsifying device, a second driving mechanism for driving the first rotating shaft to rotate, and a first driving mechanism for driving the second rotating shaft to rotate; the rotation directions of the first driving mechanism and the second driving mechanism are opposite; the frame type wall scraping assembly and the blade stirring assemblies are all arranged on the first rotating shaft; the emulsifying device is arranged at the bottom end of the second rotating shaft; the bottom end of the shell is further provided with a powder feeding opening and a slurry discharging opening; and the top end of the shell is provided with a solvent feeding opening and a vacuum generating device. The centrifugal negative-pressure powder feeding and mixing apparatus can be used to fully mixing powder and a solvent, so that mixing efficiency and stirring efficiency are improved, product quality is guaranteed, dust emission is reduced, and therefore effects of the environment protection, high efficiency and high energy efficiency are achieved.

Description

Technical field [0001] The invention relates to the technical field of reactors, in particular to a centrifugal negative pressure powder feeding and mixing device. Background technique [0002] The reactor is a device that fully stirs and mixes materials and materials. It is widely used in a type of unit equipment involving chemical reactions. The energy transfer, heat transfer, and mass transfer in the reactor (low-speed stirring, high-speed emulsification) ), environmental protection benefits and chemical reactions, namely "three transmissions, one loop and one transformation" are its important features. These features make the reactor mainly play the following roles: 1. Strengthen the uniformity of mixing between materials; 2. Mass transfer; 3. Speed ​​up the chemical reaction between materials. Therefore, improving the efficiency of "three transfers, one loop and one transformation" of materials in the reactor is one of the hot spots in the research of reactors. It can be s...

Problems solved by technology

[0003] However, the powder feeding method of the reactor currently on the market is basically feeding at the top of the reactor, and then stirring and mixing through low-speed stirring, high-speed dispersion, and mixing. This feeding method causes the material to reach this position after a long time, and the stirring efficiency is low. Uneven, large dust, quality cannot be guaranteed
