A fine-grained lightweight powder blending device

Abstract

The invention discloses a blending device for powder with a small particle size and a light weight, which comprises a powder stocker, a feeder, a material preparing groove, a liquid feeding device, a dust collector, a spraying device with an atomizing nozzle, and a ventilator; a powder feed inlet and an air outlet are disposed at the upper part of the powder stocker; a dust raising zone is disposed at the central part; a material discharging cone is disposed at the lower part; a ventilating opening, a dust collector liquid outlet, and a dust inlet are disposed on the dust collector; the atomizing nozzle is disposed in the dust collector; the ventilator is connected with the ventilating opening; the dust inlet is connected with the air outlet; a discharge hole of the material discharging cone is connected with a material inlet of the feeder; a material outlet of the feeder is connected with a material inlet of the material preparing groove; a liquid outlet of the liquid feeding device is connected with a liquid inlet of the spraying device; the dust collector liquid outlet is connected with the liquid outlet of the liquid feeding device, and then is connected with a liquid inlet of the material preparing groove. The blending device for powder with a small particle size and a light weight provided by the invention realizes accurate control of the preparation time and speed, eliminates the powder caking phenomenon in the material preparing groove during the preparation process, eliminates on-site dust pollution, and improves operation environment.

Description

technical field [0001] The invention relates to a powder batching process for preparing a solid-phase powder into a suspension in a liquid in chemical batching technology, and especially relates to a powder batching process for a solid-phase powder with a finer particle size, lower density than liquid, and insoluble in liquid or mixed with liquid. A device for compounding powders that undergo chemical reactions. Background technique [0002] In order to achieve certain specific functions of chemical products, it is usually necessary to add additives at different stages of the production process. These additives are usually in the form of powders. Due to the technical difficulty of directly adding powders to the closed reaction system, it is usually necessary to add the powders Pre-mixed as a suspension before adding. For example, the preparation of additives in the field of polyester production, the general preparation process currently used in the industry is: after the po...
