Stirring device

Abstract

The invention discloses a stirring device which comprises a housing, a motor mounted in the bottom center of the housing, a stirring shaft vertically mounted above the motor, a stirring cross beam vertically fixed to the stirring shaft, and stirring plates, wherein the upper ends of the stirring plates are embedded and fixed to the lower part of the stirring cross beam from the bottom surface of the cross beam; the stirring plates are positioned on the same side of the stirring cross beam, and the included angles between the stirring plates and the two extending outer ends of the stirring cross beam are 95-175 degrees; the stirring plates are symmetrically arranged on the two sides of the stirring shaft. According to the stirring device, the stirring plates are arranged on the stirring cross beam, so that stirring parts are added; the stirring operation is performed through the stirring cross beam and the stirring plates; the two or more stirring plates are arranged on one side of the stirring shaft in parallel and rotationally tilt to the side wall of the housing or the stirring shaft along the horizontal plane; the area of contact between the stirring plates and stirring materials is enlarged, the materials are fully stirred, and the stirring effect is good.

Description

technical field [0001] The invention relates to a stirring device, which belongs to the field of industrial application. Background technique [0002] The stirring device generally consists of a motor, a rotating rod connected to the motor, and a stirring paddle arranged on the rotating rod. The function of the stirring device is to make the liquid and gas medium forced convection and uniform mixing. Most of the stirring devices currently used in industry The devices all have a single structure, and when stirring a liquid medium with a high density, the stirring effect is not good, and the service life of the parts of the stirring device is short. [0003] The purpose of stirring: liquid-liquid mixing, gas-liquid mixing and solid-liquid mixing. The influencing factors of stirring are as follows: [0004] 1) The type, size and rotational speed of the stirrer all have an influence on the distribution of stirring power between bulk flow and turbulent pulsation. [0005] 2) T...

Problems solved by technology

[0012] For example, the invention patent whose publication number is CN103100345A and the publication date is May 15, 2013, the agitator includes a first blade and a stirring shaft connected to the power output end of the halving device at one end, and the middle part of the first blade is fixedly connected with the other end of the stirring shaft. It also includes a second blade, a sleeve sleeved on the stirring shaft and sliding along the stirring shaft, and a motor fixed on the stirring shaft. The output end of the motor is connected with a telescopic rod for pushing and pulling the sleeve. One end of the second blade is connected to the first The ends of the blades are hinged, and an adjustment rod is hinged between the other end of the second blade and the sleeve; this patent can adjust the stirring position to make the liquid stir evenly, but its blades are short and cannot achieve better stirring. Secondly, the first The number of two blades is also large, the resistance of stirring is increased, and the cost is increased.

[0013] Publication CN104014268, a patent published on September 3, 2014, proposes a stirrer, including paddles connected to the motor through a rotating rod, the lower end of the rotating rod abuts against a support seat, and the support seat There is a base, the upper end of the base is provided with a support rod vertical to the horizontal plane, the upper outer wall of the support rod is provided with threads, and the nuts for adjusting the height of the support rod are set on the threads. When the agitator rotates, there is no looseness, no swing, and The paddle will not fall off and other advantages, but the design of the paddle is too simple, and the stirring force is lacking when stirring the liquid. This patent makes the stirring effect greatly reduced when pursuing light weight and convenient movement.

[0014] Therefore, aiming at the existing disclosed technology and practical application, this patent aims to propose a new technical solution to overcome the unsatisfactory stirring effect of the existing structural design, long stirring time and high energy consumption
