Non-circular tube negative pressure-pumping alga collecting device

Abstract

The invention relates to a water surface pollutants removing device, especially a non circular pipe negative pressure suction algae gathering device, which comprises a negative pressure generator, an algae gathering box and a connecting cover; an algae gathering bag is disposed in the algae gathering box at the inlet; a gravity division board is fixed on the inner wall of the algae gathering box under the algae gathering bag; the inlet of the algae gathering box is formed on the top and connected with a suction pipeline; the outlet of the algae gathering box is formed on the bottom and connected with a draining pump through pipelines; the section shape of the suction pipeline is not circular formed by the tangency of the adjacent circular arcs or arc and line; in which, the bottom section shape of the suction pipeline is circular arc with the curvature no less than that of the both sides of the pipeline. The invention achieves the advantages of simple structure, good suction effect, large algae treating capacity, not easy to block, low water content in gathered algae, long service life and strong adaptability.

Description

technical field [0001] The invention relates to a device for removing pollutants from the water surface, in particular to a device for collecting algae. Background technique [0002] With the intensification of offshore pollution, in recent years, algal blooms such as Enteromorpha have appeared continuously in sea areas such as Qingdao in my country, which has seriously affected the image of the city, brought great inconvenience to people's lives, and caused huge economic losses. [0003] Due to the sudden outbreak of algae such as Enteromorpha, huge number, wide area of ​​influence, rapid reproduction, very high moisture content and mutual entanglement, conventional water cleaning ships are limited, and manual operation has become the main treatment method. At present, the commonly used manual operation method is to salvage the algae ashore manually with a spoon, or collect the algae with a net, and then use a pump to extract water. The above two manual operation methods ha...

[0002] With the intensification of offshore pollution, in recent years, algal blooms such as Enteromorpha have appeared continuously in sea areas such as Qingdao in my country, which has seriously affected the image of the city, brought great inconvenience to people's lives, and caused huge economic losses.

[0003] Due to the sudden outbreak of algae such as Enteromorpha, huge number, wide area of ​​influence, rapid reproduction, very high moisture content and mutual entanglement, conventional water cleaning boats are limited, and manual operation has become the main treatment method

At present, the commonly used manual operation method is to salvage the algae ashore manually with a spoon, or collect the algae with a net, and then use a pump to extract water. The above two manual operation methods have low efficiency, low safety, and high labor intensity. When Enteromorpha occurs in a large area or occurs repeatedly, the above-mentioned salvage methods are obviously limited, especially when the water pump is used for suction, the distribution of seaweed in the suction pipe is uneven, which can easily lead to blockage of the suction pipe; The water content is high, which leads to a large amount of manpower in the salvage process and is difficult to operate continuously. The transportation volume is large and the energy consumption is high.
