Description

Scraping rod for treating floaters

Technical Field

The utility model relates to the technical field of water treatment, in particular to a scraping rod for treating floaters.

Background

In the prior art, conventional technologies such as a grid net, a grid machine, a water surface floating object fishing boat, a floating object interception net and the like can only remove floating objects with a certain volume such as branches, leaves, pasture and water, garbage and the like due to large interception aperture, and can not treat oil film floating objects and floating foams generated in a subsequent process pool. In the practical production practice, the floating matters at the front end of the sedimentation tank can move into the slag discharging groove at the rear end of the sedimentation tank along with water flow, and a large amount of water resource waste is caused in the process, so that the method is poor in economical efficiency.

The sewage blocking float row adopts a cylindrical float body, the float body is usually made of foam or plastic, the float bodies are connected in series by ropes and are arranged on the surface of a water body, and floats on the surface of the water body are passively intercepted under the action of water flow.

The dirt blocking float row works in a way of passively blocking the floats, and although algae carcasses, greasy dirt and the like can be intercepted, cylindrical floats can rotate to cause leakage of the floats when the dirt blocking float row is used for actively scraping the floats. Furthermore, when the amount of floats is small, the cylindrical floats will press a part of the floats into the water during the movement. The two defects cause that the effect of the dirt blocking floating bar for actively scraping the floating objects is poor.

the rod member 1 may be made of wood, foam, plastic, or other materials capable of floating on the water surface.

In some possible embodiments, in order to effectively prevent the rod member 1 from rolling over on the horizontal plane and keep the posture stable;

and a counterweight assembly 3 positioned on the base of the triangle and connected to the rod 1.

In some possible embodiments, in order to enable the rod 1 to be effectively cleaned of floats;

In some of the possible embodiments of the present utility model,

the upper connecting rings 11 are arranged in two groups and are positioned at two ends of the rod piece 1.

When the upper connecting rings 11 are two groups, the two groups of upper connecting rings 11 are arranged along the length direction of the rod piece 1 and are positioned in connection with the rod piece 1; of course, the upper connecting ring 11 can be added in the middle of the rod piece 1, and the upper connecting ring is arranged according to the length of the rod piece 1;
