Mixing device and mixing process for polyurethane foam waste micro powder and polyhydric alcohol

Abstract

The invention discloses a mixing device and a mixing process for polyurethane foam waste micro powder and polyhydric alcohol. The mixing device comprises a tank body arranged on a fixed base, the top of the tank body is connected with a tank body cover in a sealed mode, the tank body cover is provided with a liquid material feeding port and a solid powder feeding port which are symmetrically arranged, a stirring device is arranged on the tank body cover in a penetrating mode, and the stirring device can be used for stirring materials in the tank body; an emulsifying pump is arranged below the tank body, a feeding hole of the emulsifying pump is communicated with a discharging hole in the bottom of the tank body, and a discharging hole of the emulsifying pump is communicated with a circulating feeding hole in one side of the tank body through a pipeline; and a plurality of ultrasonic dispersion devices are annularly arranged at the outer side of the tank body. The mixing process is based on the device, uniform mixing of high-viscosity materials is achieved through mixing, stirring, ultrasonic dispersion and homogeneous emulsification, the viscosity of prepared micro powder and polyhydric alcohol mixed liquid is lower than the viscosity increment of a polyhydric alcohol stock solution, the applicability of the prepared mixed liquid is improved, flying dust is not generated, and the production efficiency is high.

Description

Technical field [0001] The present invention relates to a kneading technology, and particularly relates to a mixing device and foam waste powder mixing process and a polyurethane polyol. Background technique [0002] Currently, for stirring and mixing lightweight high viscosity liquid material powder is generally divided into three main steps to add materials, mixed materials, and mixing the finished product removed, wherein the mixing step there will be difficult to mix the light of the solid powder and the high-viscosity liquid lightweight solid powder dispersed in the mixture difficult problem; due to the high viscosity material has a strong adhesive force, and therefore poor fluidity problems in the product conveyor links; conventional mixing apparatus with a simple structure means poor , a good mixing effect device structure is complex and costly. [0003] Publication No. CN211274258U Chinese patent discloses a mixing device for mixing powder and liquid, means including a cy...
