Solid-liquid mixing equipment and method

Abstract

The invention discloses solid-liquid mixing equipment. The solid-liquid mixing equipment comprises a storage tank, a first pump body, a nozzle, a material receiving pipe, a second pump body, a sand mill,wherein a feed port of the first pump body is connected to the storage tank, the tail part of the nozzle is connected to a discharge port of the first pump body, one end of the material receiving pipe is located in the material liquid spraying direction of the nozzle, a feed port of the second pump body is connected to the other end of the material receiving pipe, a feed port of the sand mill is connected to a discharge port of the second pump body and is connected to the other end of the material receiving pipe, and a discharge port of the sand mill is connected to the storage tank. The invention further discloses a solid-liquid mixing method based on the solid-liquid mixing equipment. According to the solid-liquid mixing equipment, the storage tank is separated from the sand mill, a solid-liquid mixture can be uniformly treated, so that the mixing time of feed liquid is prolonged, and therefore the mixing degree is more uniform; and the nozzle is arranged, so that ejected fluid can enter the material receiving pipe quickly, so that negative pressure is formed at the periphery of a pipe orifice of the material receiving pipe, and the materials can be sucked into the material receiving pipe.

Description

technical field [0001] The invention relates to the technical field of dispersion mixing, in particular to a solid-liquid mixing device and method. Background technique [0002] In chemical production, it is often necessary to mix solids and liquids, so solid-liquid mixing equipment is required. Traditional solid-liquid mixing equipment generally includes a container, the upper end of the container has a feeding port, and a stirring device and / or a sand mill, etc. are arranged in the container, so that during the mixing process, solid and liquid phase substances are continuously injected from the feeding port, The solid is pulverized by a sand mill, and the solid and liquid are mixed together by a stirring device. However, for some high-viscosity liquids or powders that are prone to agglomeration, the solid-liquid is not easy to mix and requires certain grinding and crushing during the mixing process. In this case, because the solid material may always float on the liquid ...

AI Technical Summary

Problems solved by technology

However, these three methods all have certain limitations. First, there are easy dead angles in the mixing process, and there may eventually be some large particles or aggregates that affect subsequent processing, and when the viscosity is high, a considerable part of the material cannot be mixed. The second is that the mixing speed is slow, and when the viscosity of the material is relatively high, it is not easy to discharge the material; the third is that vacuum or large negative pressure is used, the energy consumption is high, and air intervention may occur

[0004] Therefore, there is a need for a solid-liquid mixing equipment and method to solve the problems of low mixing efficiency and uneven pulverization of existing equipment
