Problems solved by technology

However, for particles with light specific gravity and porous structure, especially light powdery dry materials whose specific gravity is close to or lighter than that of the solvent, this preparation device reveals many shortcomings, which are characterized by large amount of dust and easy agglomeration, which seriously affects The proportion of solute consumption is high when it comes to the quality of the slurry, and the environmental pollution of the batching site is severe, causing physical and mental harm to the operators.

Embodiment Construction

[0025] As shown in Figures 1 to 7, the light powdery dry material blending device of the present invention includes a blending tank 7 and a disperser 8, the light powdery dry material 1 is added from the solid feeding port at the top of the blending tank 7, and the solvent 2 passes through the valve V-1 feeds into the tank. The end of the solvent 2 feeding pipe is equipped with a nozzle 9, and the nozzle 9 is installed inside the feeding channel of the solid material. The inside of the mixing tank 7 is provided with an agitator 10, and the agitator 10 is equipped with double-layer paddles, the upper layer is a toothed disc type paddle 11, and the lower floor is a pusher type paddle 12 (Fig. 3, Fig. 4). The distribution of the teeth 13 on the toothed disc type paddle 11 is two circles, and the orientation of the teeth 13 is respectively upward and downward, forming two circles (Fig. 5, Fig. 6); Swept propulsion blades (Fig. 7). At the bottom of the blending tank 7, there is a...

Abstract

A blending apparatus for preparing the solution or slurry of the light-weight dried and powdered material features that the solvent nozzle is arranged at the terminal end of the powdered material feeding pipe, and the stirrer in blending cylinder has upper toothed disc type paddles and lower propulsion type blades for capturing solid powder easily and preventing fly dust.

Description

technical field [0001] The invention relates to a process and a device for blending solid materials (solutes) in liquids (solvents) during chemical production, in particular to a blending device for light powdery dry materials whose specific gravity is close to or lighter than solvents, and belongs to the technical field of chemical ingredients . Background technique [0002] Batching is a common process in chemical production. Its purpose is to mix solid materials with liquid materials to form a solution, or to prepare a slurry that is relatively uniformly dispersed and can last for a long time, so that it can be processed in the next process. As far as the applicant knows, most of the industry currently adopts the device of "combining tank + disperser" for circulating batching. In this type of blending device, there is an agitator inside the blending tank, and two outlet routes are set at the bottom of the blending tank: one is a circulation route, and a disperser is inst...
