CN85203333U - Hollow shaft stirrer - Google Patents

Abstract

The utility model discloses a stirrer comprising a hollow shaft. A plurality layer of blade wheels are arranged on the shaft, and each layer of the blade wheel is provided with a plurality of hollow blades. The utility model is applicable to the stirring, mixing, and reaction of the materials of liquid, liquid phase gas, liquid phase, and liquid and solid. The utility model has the advantages of simple structure, high efficiency, lower revolution speed (a speed of 100-150 revolutions per minute is good), and short stirring time.

Description

Hollow stirrer

The utility model is a kind of hollow stirrer

Before the utility model was made, normally used agitator had push type, anchor formula, slurry formula and turbine type etc.Their common drawback is that rotating speed is had relatively high expectations, and mixing time is longer, and power consumption is big, and being difficult to up and down in the still reaches even.The purpose of this utility model designs for the above-mentioned shortcoming that overcomes push type, anchor formula, slurry formula, turbine agitator.

Technical essential of the present utility model is that it has a hollow shaft (Fig. 1 (1)).On the axle several layers impeller is arranged, every layer of impeller has several hollow blades (Fig. 1 (2)).Its hollow blade becomes bending right angle (Fig. 2 (3)) with shaft.The utility model is a centrifugal action when stirring.Kinetic energy increases, and static energy reduces, and produces negative pressure in the agitator arm center.And in the still other pressure everywhere greater than the pressure at impeller center.Everywhere material moves to the impeller center in the still.And these materials since action of centrifugal force do one's utmost outwards to throw away, thereby in the short period of time in the still upper, middle and lower even easily.

Description of drawings: Fig. 1 is the hollow stirrer front view, the hollow shaft 2 of 1----hollow blade; Fig. 2 agitator mansion view 3---the bending right angle of hollow blade.

Characteristics of the present utility model and advantage are: wide accommodation. Can be used for liquid, liquid phase, the stirring of gas, liquid, liquid, solid-phase material, mixing, reaction. (material stirring in the scope of viscosity=0.369P) is obtained good result equally for newton-type and non newtonian type pseudoplastic fluid. Especially for liquid, solid-phase material stir, for example its liquid water, its solid 1.25mm The grains of sand are done test. Stir with propeller agitator, when rotating speed is 100～150 rev/mins. The sand of bottom stirs motionless in the still. When rotating speed is brought up to 600 rev/mins. The sand of its bottom can stir, but is difficult at the middle and upper levels stir, and stirs with hollow stirrer, when rotating speed is 100～150 rev/mins. In 2～3 minutes. Upper, middle and lower all reaches even in the still. Rotating speed of the present utility model requires lower, and per minute transfers to suitable with 100～150. It has simple in structure, mixing time weak point, stirring efficiency advantages of higher.

Claims (2)

1, the utility model hollow stirrer has a shaft and several blades to constitute, and it is characterized in that described agitator has a hollow shaft (1).The several layers impeller is arranged on hollow shaft.Every layer of impeller has several hollow blades (2).

2, according to the described agitator of claim 1, it is characterized in that its hollow blade becomes bending right angle (3) with shaft.
