Description

Low-speed stirring paddle

Technical Field

The utility model relates to a novel low-speed stirring rake belongs to chemical machinery technical field.

Background

In many processes where gentle agitation is required, for example, lime, soda, alum, etc. are added to water to form a precipitate or floc, it has been found that water and chemicals are first thoroughly mixed at a relatively high rate and then the mixture is agitated at a relatively low rate for a long period of time. High speed stirring is not a great problem because the high speed running stirrer can generate high turbulence and strong vortex, thereby achieving the requirement of uniform mixing. However, in the case of low-speed stirring, there are problems that the stirring center has a small horizontal flow and vertical flow velocity, the movement in the vicinity of the stirring shaft is very slow, and a dead zone and a poor-mixing zone are formed.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned not enough, provide a novel stirring rake for low-speed forms the problem in blind spot and mixed bad district at stirring center when can improve the low-speed stirring better.

According to the technical scheme provided by the utility model, a low-speed stirring rake, including wheel hub, horizontal oar, perpendicular oar and frame oar, wheel hub has two, locates the top and the bottom of agitator respectively, wheel hub includes the wheel hub axle sleeve, and the wheel hub axle sleeve is used for the fixed mounting (mixing) shaft, and the both sides welding outside the wheel hub axle sleeve is provided with two horizontal oars, and the horizontal oar is equipped with the frame oar outward, has a plurality of perpendicular oars between horizontal oar and the frame oar.

As a further improvement, the outer frame paddle comprises two side paddles and two arc paddles, wherein the two side paddles are respectively connected with the two horizontal paddles, and the two side paddles are connected with the arc paddles.

As a further improvement of the utility model, the quantity of the vertical paddles is determined to be two to ten by the diameter of the paddles, and the hub is used as the axle center symmetrical arrangement.

As a further improvement of the utility model, the angle between the horizontal blade and the horizontal line is 30-60 degrees.

As a further improvement, the vertical paddle and the vertical face form a certain included angle, and the included angle between the vertical paddle and the vertical face is reduced from the outside to the inside.

As a further improvement of the utility model, the width of the vertical paddle is reduced from the center to the outer side.

As a further improvement of the utility model, the outer frame paddle is pressed close to the tank bottom.

Compared with the prior art, the utility model, have following advantage:

(1) the utility model adds a plurality of vertical paddles between the horizontal paddle and the outer frame paddle for improving the central flow of the stirring paddle at low speed;

(2) adopt the utility model discloses the perpendicular oar of stirring rake constitutes certain contained angle with the facade, from outside to interior contained angle by diminishing greatly, the oar is wide by little grow, stirring center forms the problem in blind spot and mixed bad district when improving the low-speed stirring well.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

The utility model provides a low-speed stirring rake, includes wheel hub 1, horizontal oar 2, perpendicular oar 3 and frame oar 4, wheel hub 1 has two, locates the top and the bottom of agitator respectively, wheel hub 1 includes wheel hub axle sleeve 5, and wheel hub axle sleeve 5 is used for the fixed mounting (mixing) shaft, and the both sides welding outside wheel hub axle sleeve 5 is provided with two horizontal oars 2, and horizontal oar 2 is equipped with frame oar 4 outward, has a plurality of perpendicular oars 3 between horizontal oar 2 and the frame oar 4.

The number of the vertical paddles 3 is determined to be two to ten by the diameter of the paddle, and the vertical paddles are symmetrically arranged by taking the hub 1 as an axis.

The horizontal paddle 2 forms an angle of 30-60 degrees with the horizontal line.

Erect oar 3 and facade and constitute certain contained angle, and erect oar 3 and by big diminishing with the contained angle of facade from the outside to interior, the facade is the facade that horizontal oar extending direction is the crest line. Taking four vertical paddles 3 as an example, as shown in fig. 1, an included angle of 40-50 degrees is formed between the vertical paddle 3a and the vertical surface, an included angle of 20-30 degrees is formed between the vertical paddle 3b and the vertical surface, and the width of the vertical paddle 3 decreases from the center to the outer side, that is, the width of the vertical paddle 3a is smaller than that of the vertical paddle 3 b.

The outer frame paddles 4 comprise side paddles 6 and arc paddles 7, the side paddles 6 are provided with two numbers and are respectively connected with the two horizontal paddles 2, the arc paddles 7 are connected with the two side paddles 6, and the side paddles 6 and the vertical surface form an included angle of 60 degrees.

The outer frame paddle 4 is close to the bottom of the tank.

The utility model discloses the theory of operation of product is as follows: when the motor passes through speed reducer speed reduction low-speed rotation, it is rotatory to drive epaxial novel low-speed stirring rake, stirring rake one side is erect the paddle and is moved liquid to the periphery step by step, the paddle is erect the paddle and is moved liquid to the center pin step by step to the opposite side, near the axle liquid constantly is replaced under the effect of erecting the paddle, the gradient and the width that change gradually provide the more even radial flow of liquid, through this kind of mode, can prevent near any blind spot or the stagnant area in jar center effectively, and stir whole liquid, thereby make the even stirring of whole liquid.
