Problems solved by technology

However, although the setting of the deflector increases the bottom flow rate and the working water depth, it can also improve the oxygenation capacity, but the addition of the deflector will deteriorate the water flow conditions. Tests show that increasing the deflector will increase the power consumption by 15-30%, so the power efficiency Not only has it not increased, but it has decreased, so it is actually not cost-effective
[0004] In addition, the blades of the existing rotary brushes all use metal blades without exception and are separated from the hub bushing, and are fixed on the hub bushing by bolts during installation. The required power is also high, which is another reason why its power efficiency is not high; and the installation of the blades one by one is heavy and difficult, and the long-term operation of beating the water surface vibration may also easily cause the bolts to loosen and eventually fall off, which needs to be supplemented. Increased maintenance and replacement workload

Embodiment 1

[0027] Example 1: see figure 1 , 2 , The aeration rotary brush of the present invention is composed of glass fiber reinforced resin molded into two symmetrical pairs. The rotating brush blade 1 is in a curved arc shape, and is integrally connected with a threaded hub sleeve 2, and each blade has pits 3 on both sides. During aeration operation, the curved convex surface is transferred into the water.

Embodiment 2

[0028] Example 2: see image 3 , As in the first embodiment, the surface (arc convex surface) of the rotating brush blade that is turned into the water surface has arc-shaped convex reinforcement ribs 4.

Embodiment 3

[0029] Example 3: See Figure 4 , As in Example 1, the turning brush blades into the water surface (arc-shaped convex surface) have concave arc-shaped convex reinforcement ribs 5.

Abstract

The invention improves an aeration rotary brush for water treatment, which is characterized in that a rotary brush blade is of a curve arc shape. Compared with the existing straight blade, the invention greatly reduces the running resistance of water to the blade when entering water and running resistance to the blade in the water, effectively prevents the deformation and break-off of the blade after a long time operation, improves the operation rotation speed, and the oxygenation capacity and the plugflow effect on the bottom flow, improves the operating depth by about 10-15%, and other measures are taken to improve dissolved oxygen, thus the oxygenate dynamic efficiency and the oxygenation capacity are significantly improved compared with the prior art.

Description

Technical field [0001] The invention is an improvement on the aeration rotary brush for water treatment, and in particular relates to an aeration rotary brush with strong propulsion capability, low energy consumption, high oxygenation and long service life. Background technique [0002] Because the rotating brush has a relatively higher speed than the rotating disk, it is used for water treatment with a fast push flow rate and high oxygenation efficiency. This is its advantage, but the energy consumption is relatively higher than that of the rotating disk, the power efficiency is low, and the diameter is generally not restricted by the strength of the blade. More than 1 meter, so the working water depth is shallower than the turntable, and the working water depth is generally not more than 3.5 meters, which is its shortcoming. The basic structure of the aeration rotating brush in the prior art includes a central hub sleeve and rotating brush blades fixed on the circumference of t...
