Abstract
The invention discloses a vertical hydrofoil paddle stirring device for water treatment. The vertical hydrofoil paddle stirring device comprises a motor, a speed reducer, bearings and a shaft, wherein the motor is arranged above the speed reducer; the bearings are arranged under the speed reducer; the free tail end of the shaft is provided with a hub; the circumferential surface of the hub is provided with three lifting lugs which are uniformly arranged in a welding way; the lifting lugs and the upper surface of the hub are in 45-degree included angle arrangement; the lifting lugs are provided with hydrofoil paddles; the length of each hydrofoil paddle is 10m; each hydrofoil paddle is in bending arrangement and comprises a first bending blade, a second bending blade, a third bending blade and a fourth bending blade; the first bending blades are connected with the lifting lugs through plural bolts; each first bending blade and the corresponding second bending blade are in 150-degree included angle arrangement; each second bending blade and the corresponding third bending blade are in 140-degree included angle arrangement; each third bending blade and the corresponding fourth bending blade are in 130-degree included angle arrangement. According to the vertical hydrofoil paddle stirring device disclosed by the invention, the hydraulic retention time is increased, the energy consumption is reduced, and the floating force is increased.
Description
technical field [0001] The invention relates to the technical field of environmental water treatment, in particular to a vertical hydrofoil stirring device for water treatment. Background technique [0002] With the development of urban construction and the acceleration of urbanization in our country, more and more pollution is caused, and the problem of urban water pollution is particularly prominent. The sewage treatment capacity of most cities in the country is far from meeting the actual needs, and there is a lot of room for the development of sewage treatment. Urban sewage treatment facilities have also become an indispensable part of modern urban economic development and water resource protection. Agitators have become the most commonly used of sewage treatment equipment. [0003] As the main sewage treatment equipment, the sewage treatment agitator has a wide range of uses and is suitable for the treatment of sewage in aeration tanks and anaerobic tanks in industrial...
