A river oil slick removal device

Abstract

The invention discloses a device for removing slick oil in a river course, comprising: a bracket, and a main body erected on the bracket and movably connected with the bracket, the main body includes a hollow cylinder, a sealing cover and several blades, wherein the outer surface of the hollow cylinder is along the A groove is opened in the axial direction, and a through hole is opened at the bottom of the groove. The outer surface of the hollow cylinder and the surface of the groove are covered with an oleophilic layer; A hollow cone is extended inside, the bottom of the hollow cone is set on the inner wall of the hollow cylinder, the bottom and top of the hollow cone are provided with openings, and the bottom openings are facing the corresponding through holes, the size of which is not less than The size of the corresponding through hole; the sealing cover is arranged at both ends of the hollow cylinder, and at least one of them can be opened; the vane protrudes outward from the outer surface of the hollow cylinder in a radial direction. The device does not need to be equipped with a power device, and has high oil removal efficiency, simple structure, low price, movable, convenient use and low maintenance cost.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a device for removing floating oil in a river course. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and urban and rural water environments have encountered unprecedented threats. Urban and rural rivers are severely degraded due to pollution and ecosystems. The water quality of the rivers is basically at the V or inferior V level. Most of the rivers are seriously polluted, eutrophic, lack of oxygen, black and smelly, resulting in a severe environmental and ecological situation. In addition, due to river shipping leakage or illegal discharge by coastal enterprises, more and more oil pollution is floating on the surface of the river. In recent years, oil pollution has always been a major problem in river treatment and management due to its difficulty in cleaning up, wide s...

Problems solved by technology

In principle, there is nothing wrong with this collection method. The only thing that is difficult to guarantee is that the draft of the bell mouth cannot match the flow rate of the pump. If the draft is too shallow, the center of the bell mouth will form a vortex to suck in air and damage the pump; if If the draft is too deep, there will be more water and less oil in the oily sewage, which will lose the meaning of collecting oil slicks. Therefore, the use of this collection device has certain limitations. When the flow rate of the water pump is determined, the draft of the bell mouth is relatively determined. For still water, it is more convenient to use, but for more volatile water, the situation is completely different

Moreover, the water pump needs a motor for power, which has the problem of energy consumption, and the equipment is relatively heavy, so it is not suitable for long-term maintenance of large-area river water surfaces.
