Description

Submersible mixer for sewage treatment

Technical Field

The invention relates to a submersible stirring technology, in particular to a submersible stirrer for sewage treatment.

Background

The submersible mixer is an important sewage treatment mixing machine, is suitable for urban and rural sewage treatment plants, and is widely applied to biochemical reaction tanks such as anaerobic tanks, sedimentation tanks, aeration tanks and the like. The submersible mixer is used for mixing fluid in a sewage tank, in order to prevent activated sludge rich in microorganisms from settling at the bottom of the tank and enable the activated sludge to be suspended in the tank, the fluid in the tank is required to be in motion, the speed of the fluid in the tank is generally required to be more than 0.1m/s, the average speed is required to be kept about 0.3m/s, and the mixing effect is optimal. In this state, the microorganism and the sewage are fully reacted to achieve the mixing and stirring effects.

At present, a submersible mixer commonly used at home and abroad is a single-impeller mixer, namely, an impeller is arranged on a submersible motor, and the number of blades is generally three or two. The submersible mixer is fixed on the pool wall or is arranged close to the pool wall through a guide rod. This has some disadvantages, mainly in that only a part of the fluid in the sump is circulated, i.e. only the liquid in front of the submersible mixer is circulated. If the pool is large, most of the liquid in the pool will not be stirred, and the solid matters in the pool will be precipitated. At present, the common solution is to replace a submersible mixer with a large-diameter and high-power impeller or install a plurality of submersible mixers at different positions in the tank, but the mixing effect of the submersible mixer on the sludge layer which is deposited more at the bottom of the tank is not good.

Through search, the related patent applications at present are: a submersible mixer with cutting function, application number 201020295726. X; a submersible plug flow blender impeller of glass fiber reinforced plastic, application No. 200320126437.7. These patents improve blender performance, primarily by modifying existing blade materials and adding impeller attachment parts. Additionally, a mixer and method for mixing a liquid in a basin application No. 20078009211.X, a sewage treatment mixer; application No.: ZL 201220277048.3; ZL 201220286274.8; ZL201220285965.6, these four patents are mainly when stirring to great pond, some agitator transformation and the new measure of method that take, but all restrict to the processing and method to two dive impeller, do not solve the technical problem how to stir the sludge blanket that has already settled at the bottom of the pool yet.
