AI Technical Summary

Technical Problem

Existing DTBP production equipment suffers from uneven mixing, widened residence time distribution, and safety risks during the mixing of multiple raw materials. In particular, when there are large differences in the specific gravity and viscosity of the raw materials, the fixed structure is difficult to adapt to changes in fluid dynamics conditions.

Method used

A multi-raw material precise proportioning mixing device suitable for DTBP microreactors was designed, including a plate reactor, a mixing guide shell, an adjustment component, a flow channel switching component, and a secondary mixing unit. The valve body and flow channel structure are adaptively adjusted by an electromagnet push rod, combined with the dynamic mixing of stirring blades and rotating rods, to achieve adaptive reconstruction of the flow channel structure and multi-stage flow splitting, thereby improving the mixing uniformity.

Benefits of technology

It achieves efficient and uniform mixing under different raw material specific gravities, reduces local hot spots and safety risks, and improves mixing efficiency and molecular diffusion effect, making it particularly suitable for the treatment of heat-sensitive substances.

Abstract

The application relates to the technical field of mixing, in particular to a multi-raw-material precise proportioning and mixing device suitable for DTBP micro-reaction, which comprises a plate-type reactor, a raw material supply unit, a proportioning and mixing unit and a linkage adjusting mechanism. The raw material supply unit comprises methyl ethyl ketone feeding pipes and hydrogen peroxide feeding pipes for respectively feeding methyl ethyl ketone and hydrogen peroxide, a DMP feeding pipe for feeding DMP and a sodium sulfate feeding pipe for feeding sodium sulfate. The proportioning and mixing unit comprises a first mixer, a second mixer, a third mixer and a mixing flow guide shell arranged in the three mixers. Two mixing pipes are arranged at the upstream of the mixing flow guide shell. The linkage adjusting mechanism comprises an adjusting assembly arranged at the upstream of the mixing flow guide shell, an electromagnet push rod for controlling the adjusting assembly and a flow channel switching assembly linked with the adjusting assembly. The flow channel switching assembly comprises a movable connecting seat which can be driven to move by the electromagnet push rod, and the movement of the movable connecting seat can synchronously change the guiding state of the fluid after passing through the adjusting assembly.
