Mechanical algae removing device for floating algae in water channels

Abstract

The invention discloses a mechanical algae removing device for floating algae in water channels. The device comprises a totally rectangular frame; a plane of the frame faces a water flowing direction;the frame is aslant arranged in a manner of left-low and right-high; the top of the frame is fixedly connected with a mounting frame after being bent to the right side; a motor speed reducer is arranged on the right side of the mounting frame; a power output end of the motor speed reducer is in transmission connection with a transmission chain wheel through a driving chain; the driving chain wheel, a first driven chain wheel, a second driven chain wheel and a third driven chain wheel are in transmission connection through at least two traction chains; an algae intercepting mesh is arranged between two adjacent traction chains; spraying systems towards water tanks are respectively arranged in the traction chains on the mounting frame; and the parts, below the motor speed reducer, of the algae intercepting meshes are positioned between the spraying systems and the water tanks. The device has the characteristics of light structure, high rigidity, good stability, convenience for installation and disassembly, high cost performance, excellent algae removing effect and incapability of causing secondary pollution to water sources.

Description

technical field [0001] The invention belongs to the technical field of water conservancy construction or maintenance, and in particular relates to a mechanical algae removal device for planktonic algae in a water delivery channel. Background technique [0002] After the main channel of the middle line of the South-to-North Water Diversion Project is opened, a large number of planktonic algae will grow in the channel at the turn of spring and summer due to the nutrient-rich water body, which will seriously affect the quality of the water body and increase the post-treatment cost of the waterworks. In order to avoid such problems, it is necessary to remove planktonic algae in the water during the water delivery process. At present, there are two kinds of algae removal methods at home and abroad, physical and chemical. However, since the water source transported by the South-to-North Water Diversion Project is drinking water, the chemical residues of algae removal by chemical m...

Problems solved by technology

In the process of trial operation, it was found that the rigidity of the algae-blocking grid mechanism was insufficient, which could easily cause the chain to fall off and the grid to be twisted.

At the same time, it was found that in the high-pressure spraying facilities, the impact force of the liquid column flow generated by the nozzle was low, and the removal of algae pollution was not complete. Normal use and algae and pollution removal effect
