Problems solved by technology

Due to the large difference in the characteristics of the stirred zone and the non-stirred zone, it is difficult to achieve the requirements of uniform shearing and rapid mixing in ordinary mixers
For example, the up-and-down and rotary agitator, the forward-reversing and up-and-down composite agitator all have very good mixing behavior, but their shear distribution is extremely uneven; a shortcoming of future technologies is that most of them are first-stage Stirring, uneven stirring, continuous stirring and discharging, and the sound insulation effect of the existing mixing equipment is not very good
These devices are not well suited for applications requiring both uniform shear and good mixing due to their good behavior in only one aspect

Abstract

The invention discloses a multi-stage stirrer. The multi-stage stirrer comprises a machine shell and a stirring motor located on the upper side of the machine shell. A rotating shaft of the stirring motor is arranged inside the machine shell. The machine shell is divided into multiple partition chambers from up to bottom. A partition plate of each partition chamber is provided with a discharging opening. The top of the machine shell is provided with a feeding opening. The bottom of the machine shell is provided with a master discharging opening. The feeding opening, the discharging openings and the master discharging opening are distributed in a shape like the Chinese character 'gong'. The portion, located in each partition chamber, of the rotating shaft is provided with a stirring impeller. The machine shell comprises an outer wall and an inner wall. Multiple temperature adjusting devices are circumferentially distributed between the outer wall and the inner wall. A temperature sensor is arranged in the lowest partition chamber of the machine shell. The outer wall sequentially comprises a stainless steel layer, an acoustic-absorbing cotton layer, a cellular board layer and an acoustic-absorbing coating layer from inside to outside. The feeding opening is provided with a flow meter. The master discharging opening is provided with an electromagnetic valve. The multi-stage stirrer is simple in structure, adjustable in temperature, good in sound insulating effect and capable of achieving multiple stages of stirring and a good raw material stirring effect.

Description

technical field [0001] The invention relates to the field of raw material mixing machinery, in particular to a multistage mixer. Background technique [0002] The mixer occupies a large proportion in the chemical industry and the construction industry. Its role is mainly to provide a place for material mixing or chemical reaction. For this reason, the device is often required to have uniform shear distribution and good mixing behavior. Such as multi-phase dispersion system, multi-phase polymerization system, etc. that need to control the particle size. Due to the large difference in the characteristics of the stirred zone and the non-stirred zone, it is difficult to achieve the requirements of uniform shearing and rapid mixing in a common mixer. For example, the up-and-down and rotary agitator, the forward-reversing and up-and-down composite agitator all have very good mixing behavior, but their shear distribution is extremely uneven; a shortcoming of future technologies is...
