Bladeless stirrer

Abstract

The invention provides a bladeless stirrer which comprises a shaft sleeve and a disc body, wherein the disc body is connected with a stirring shaft of the stirrer through a shaft sleeve; the disc body is free of stirring blades; the outer side surface of the disc body consists of a plurality of planes which are connected in sequence; a stirring ridge is formed at connecting parts of every two planes; a cavity and water flow through holes are further formed in the disc body; the water flow through holes consist of middle ejection holes and lateral flow through holes; the middle ejection holes are communicated with the cavity; the lateral flow through holes penetrate through the side wall of the disc body. The bladeless stirrer is not provided with blades and is not of a smooth disc structure, either, but a compromise proposal is adopted, that is, stirring ridges are formed on the disc body, so that on one hand, problems caused by stirring blades can be solved, and on the other hand, a stirring effect can be enhanced through the stirring ridges. Due to the water flow through holes in the disc body, centrifugal ejection flow and annular ejection flow can be integrated in the stirring process, and the stirring efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a mixer, which is suitable for mixing fluids in the fields of chemical industry, environmental protection and the like. Background technique [0002] For the mixing and stirring of fluids, agitators with blades are mostly used. The size of the agitator with blades needs to match the size of the tank, and larger tanks need to be matched with larger blade agitators. The motor of the blade agitator cannot be directly connected to the stirring shaft, and the motor needs to be connected to a reducer to be connected to the stirring shaft. Its rotating speed is 20-130 rev / min. If there are entanglements in the fluid to be agitated, they will wrap around the blades. Therefore, the blade agitator is not very ideal in terms of efficiency and effect in use. [0003] In order to solve the above problems, the applicant applied for a stirring device on 2015.08.10 and disclosed it on 2015.11.11. It is not equipped with stirring blades, bu...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a wingless stirrer. Although there are no blades, it is not set into a disc structure. Instead, it takes a compromise solution to form stirring corners on the disc body. On the one hand, It can solve the problems caused by stirring blades, and on the other hand, it can supplement the stirring effect by stirring edges and corners
