Solid-liquid mixing equipment and solid-liquid mixing method

Abstract

The invention discloses solid-liquid mixing equipment. The solid-liquid mixing equipment comprises a storage tank, a pump body, a spray nozzle, a material receiving pipe and a shearing device, whereina material inlet of the pump body is connected with the storage tank; the tail part of the spray nozzle is connected with a material outlet of the pump body; one end of the material receiving pipe islocated in a feed liquid spraying direction of the spray nozzle; a material inlet of the shearing device is connected to the other end of the material receiving pipe, and a material outlet of the shearing device is connected to the storage tank. The invention also discloses a solid-liquid mixing method. The solid-liquid mixing method comprises the following steps: adding to-be-mixed feed liquid in the storage tank; spraying the feed liquid from the spray nozzle under the driving of the pump body; enabling the feed liquid to enter the shearing device through the material receiving pipe, and enabling the feed liquid to flow into the storage tank after shearing and mixing. According to the solid-liquid mixing equipment disclosed by the invention, the storage tank is separated from the shearing device, solid-liquid mixed materials can be uniformly treated, a phenomenon of doping of large particles cannot occur, and particles can also be prevented from being excessively smashed; through the arrangement of the spray nozzle, ejected fluid is enabled to quickly enter the material receiving pipe, so that negative pressure is formed at the periphery of a pipe opening of the material receiving pipe, and 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 shearing device, 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 shearing device, 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...

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
