Novel efficient vertical circulation stirrer

Abstract

The invention discloses a novel efficient vertical circulation stirrer which comprises a stirring tank. A bottom non-slip mat is fixedly connected on the bottom of the inner cavity of the stirring tank. A stainless steel center cylinder is movably connected on the top of the bottom non-slip mat, and a limiting cylinder is movably connected on the top of the stainless steel center cylinder. The invention relates to the technical field of circulation stirrers. According to the novel efficient vertical circulation stirrer, the rotary impeller rotates to suck water to perform high speed injectionfrom water outlets, spraying and diffusing to the bottom of the stirring tank at a certain angle in a 360-degree direction, and a plurality of annular main flow belts are formed. The flow speed of themain flow belt is high, a turbulent flow area taking the main flow belt as the center is formed around the main flow belt, water in the whole tank is enabled to form a large circulation of turning upand down, large-area three-dimensional circulation stirring is realized, sludge in the tank is always in a turning and suspending state, the phase contact surface is increased, the stirring dead angle is eliminated, the purpose of uniform and mild stirring is achieved, and the energy-saving effect is remarkable on the premise of meeting the process requirements.

Description

technical field [0001] The invention relates to the technical field of circulating flow agitators, in particular to a novel high-efficiency vertical circulating flow agitator. Background technique [0002] Sewage treatment: In order to purify sewage to meet the water quality requirements for discharge into a water body or reuse, sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc. Various fields are increasingly entering the daily life of ordinary people. According to the source of sewage, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc. Sewage is the sewage produced in daily life, which refers to the complex mixture of various forms of inorganic and organic substances, including: floating and suspended solid partic...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of high-efficiency vertical circulation agitator, which solves the problem that the muddy water mixture at the bottom cannot be effectively and fully stirred and mixed. The shaft is prone to deformation during the process, and it is prone to breakage after a long time, which leads to the problem that the failure rate of the agitator increases linearly
