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.

Example Embodiment

[0035] Example 1

[0036] like figure 1 , 2 As shown, a stirrer comprises a casing 1, a motor 2 at the bottom center of the installation casing 1, a stirring shaft 3 vertically mounted on the top of the motor 2, and a stirring beam 4 that is vertically fixed with the stirring shaft 3; also includes arc stirring plate 5; two arc-shaped stirring plates 5 are respectively arranged on both sides of the stirring shaft 3, and the arc-shaped stirring plates are fixed on the stirring beam; the distance between the bottom end of the arc-shaped stirring plate and the bottom of the shell 1 is 5mm; the stirring plate Vertically fixed and arranged at both ends of the stirring beam; the stirring plate is arc-shaped and relatively symmetrically arranged at both ends of the stirring beam, and the stirring beam passes through the center of the arc-shaped stirring plate, and a stirring part is added. The stirring plate 5 stirs at the same time, which increases the stirring times and improves ...

Abstract

The invention discloses a stirrer which comprises a housing, a motor mounted in the bottom center of the housing, a stirring shaft vertically mounted above the motor and a stirring cross beam vertically fixed to the stirring shaft, and is characterized by further comprising stirring plates vertically fixed to the two ends of the stirring cross beam, wherein the stirring plates are arc-shaped and are oppositely and symmetrically arranged at the two ends of the stirring cross beam; the stirring cross beam penetrates through the centers of the arc-shaped stirring plates. According to the stirrer, 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, so that the stirring frequency is increased and the stirring effect is improved; through the arrangement of the arc-shaped stirring plates, while the effort and energy are saved during stirring, the stirring efficiency is greatly improved and the stirring effect is relatively remarkable; due to layer-by-layer design of trapezoidal radian of the arc-shaped stirring plates, 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 stirrer, which belongs to the field of industrial application. Background technique [0002] The agitator 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 agitator is to make the liquid and gas medium forced convection and uniform mixing. Most of the agitators currently used in industry All the mixers 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 mixer parts 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 agitator have an effect on the distribution of agitation power between bulk flow and turbulent pulsations. [0005] 2) Stirring viscosity of different media viscosities ...
