Description

Technical Field

[0001] The utility model relates to the technical field of medicine powder wetting, in particular to a medicine powder pre-wetting device. Background Art

[0002] Some industries use high-viscosity liquid agents, such as coagulants used in the water treatment industry, enhancers used in the papermaking industry, lubricants used in the oil drilling industry, etc. In order to reduce transportation costs and improve efficiency, these high-viscosity agents are usually purchased on the market in powder form and need to be mixed into liquid form before use. However, some powdered materials need to be moistened with water before they can be stirred to prevent dust from flying during the stirring process, which causes waste of resources. During use of the existing powder mixing device, usually all the materials are added first, and then an appropriate amount of water is added during the stirring process, and then the powder is stirred. However, when using this stirring method, it is found that since the materials have been completely added, most of the materials cannot be moistened by water when water is added, resulting in powder flying at the beginning of stirring because some materials are not moistened. Technical personnel in the industry have developed a process of wetting before stirring, such as the authorized patent CN202321358382.6, a powder and wetting agent mixing and molding kettle, which can solve the above problems, but the structure inside the kettle is slightly cumbersome, and subsequent repair and maintenance will be more troublesome. Our technicians have also designed a pre-wetting device based on the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention will be described below based on the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. However, it is worth noting that the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. However, for the parts that are not described in detail, those skilled in the art can also fully understand the present invention.
