Abstract
A rotatable water treatment device including a hollow shaft and multiple filtering units is provided. The hollow shaft has an axis hole, an external wall and a plurality of through holes defined through the external wall and communicating with the axis hole. The multiple filtering units watertightly mounted on the external wall of the hollow shaft, and each of the filtering units includes a center hole, two clipping nets, a supporting net and two filtering membranes. The supporting net is mounted between the clipping nets and two filtering membranes sandwiches the clipping nets such that the filtering membranes can be prevented from sinking into the meshes of the supporting net with the pump effect to accelerate the conducting of the water-filtering.
Claims22
A water treatment device, comprising:
- a hollow shaft, and including:
- an axis hole;
- an external wall;
- and
- a plurality of through holes defined through the external wall and communicating with the axis hole;
- and
- multiple filtering units watertightly mounted on the external wall of the hollow shaft, and each of the filtering units including:
- a center hole holding the hollow shaft and communicating with the through holes;
- two clipping nets;
- a supporting net mounted between the clipping nets;
- and
- two filtering membranes sandwiching the clipping nets;
- wherein the supporting net, the clipping nets and the filtering membranes are arranged in a stacked manner.
A rotatable water treatment device, comprising:
- a raw water treatment tank;
- at least one hollow shaft rotatably mounted in the raw water treatment tank, and each of the at least one hollow shaft including:
- an axis hole;
- an external wall;
- and
- a plurality of through holes defined through the external wall and communicating with the axis hole;
- and
- multiple filtering units watertightly mounted on the external wall of each one of the at least one hollow shaft, and each of the filtering units including:
- a center hole holding one of the at least one hollow shaft and communicating with the through holes;
- two clipping nets;
- a supporting net mounted between the clipping nets;
- and
- two filtering membranes sandwiching the clipping nets;
- wherein the supporting net, the clipping nets and the filtering membranes are arranged in a stacked manner.
