Rapid underwater algae removal mechanical device

Abstract

The invention discloses a rapid underwater algae removal mechanical device. The mechanical device comprises a duckweed removal device body A and an algae removal device body B, an opening is formed inthe center of the bottom of the duckweed removal device body A, the duckweed removal device body A sleeves the algae removal device body B through threads, the duckweed removing device body A comprises a duckweed removal outer barrel (17), a top cover (15) covers a top opening of the duckweed removal outer barrel (17) in a sealed mode, a cylindrical check ring (16) with the depth smaller than thedepth of the duckweed removal outer barrel (17) is fixedly arranged on the inner bottom surface of the top cover (15), blades (14) are arranged in the cylindrical check ring (16), the algae removal device body B comprises an algae removal outer barrel (7), a coarse filter screen (3) is arranged at a water inlet in the side wall of the top edge of the algae removal outer barrel (7), an algae removal device top cover (2) covers a top opening of the algae removal outer barrel (7) in a sealed mode, and a filter barrel (4) of a stainless steel filter screen is concentrically arranged in the algaeremoval outer barrel (7). The mechanical device has the advantages that the algae removal and duckweed removal functions can be achieved, the use is simple, the algae removal efficiency can be improved, the energy source for extracting algae liquid can be saved, and the automatic cleaning function can be achieved.

Description

technical field [0001] The invention belongs to the field of water body eutrophication treatment, and in particular relates to a mechanical device for rapidly processing the outbreak of a small number of weeds and algae caused by the eutrophication of lake water bodies. Background technique [0002] As people pay more and more attention to water eutrophication, related research on water eutrophication treatment has been driven, and certain results have been achieved. Among them, mechanical algae removal has no secondary pollution and low cost, and can quickly control individual indicators to make mechanical removal of algae. Algae became a good method. [0003] At present, my country has two invention patents for ship-type mechanical algae removal ships, as well as several utility model and appearance patents for mechanical algae removal. Basically, the methods of coarse sieving and microfiltration are used to extract the water body into the device, collect, Multi-part conce...

Problems solved by technology

The process is very complicated and has the following disadvantages: 1. It is necessary to use a pump to lift the algae liquid to the inside of the device and then process it. The water liquid that is lifted or extracted causes energy waste; Filter screens and conveyor belts are likely to cause algae blockage in multiple places, and anti-clogging devices such as backwashing in multiple places consume a lot of energy; 3. The device needs to be suspended on the water surface, and the device is large in size, which affects the landscape of the lake
