Problems solved by technology
Agitators or stirring tanks are usually used, but the currently used agitators degrade COD and multiphase dispersion, have poor mixing effects and take a long time, resulting in high energy consumption and low processing capacity, which seriously restricts the processing effect and production capacity of related materials.

The invention relates to a degradation tank suitable for degrading COD. A self-priming spray-type high-efficiency degradation tank suitable for degrading COD is characterized in that it includes a tank body, a lower diversion vertical cylinder, a slurry suction pipe, a connecting column, an air dispersion cylinder, a spray grid, an upper diversion vertical cylinder, Connect the tie rods, transmission frame, transmission base, diversion partition, overflow tank, central hollow shaft, radial blades and rotating mechanism; there is a lower diversion vertical cylinder at the bottom of the center inside the tank body, and the lower diversion vertical cylinder passes through The connecting column is fixed on the bottom surface inside the tank body; an upper diversion vertical cylinder is arranged above the center of the tank body, and the upper diversion vertical cylinder is connected with the lower end of the transmission frame by a connecting rod, and a hole is arranged on the upper diversion vertical cylinder There is a trumpet-shaped injection grid plate under the upper diversion vertical cylinder, and the upper end of the jet grid plate is fixedly connected with the lower end of the upper diversion vertical cylinder; the middle part of the tank body is provided with an air flow dispersion cylinder. The degradation tank can realize automatic slurry suction and fully stir the materials to achieve the purpose of degrading COD, or dispersing and mixing gas-liquid or gas-liquid-solid multiphase substances.
Description
technical field [0001] The invention relates to a self-priming spray type high-efficiency degradation tank suitable for degrading COD. Background technique [0002] In the chemical process, environmental engineering, municipal engineering and mineral processing, it is usually necessary to degrade the liquid slurry in the production process, or disperse and mix gas-liquid or gas-liquid-solid multiphase substances. Agitators or stirring tanks are usually used, but the currently used agitators degrade COD and multiphase dispersion, the mixing effect is poor, and it takes a long time, resulting in high energy consumption and low processing capacity, which seriously restricts the processing effect and production capacity of related materials. [0003] The present invention draws lessons from the characteristics of gas-liquid-solid material mixed mineralization in the mineral processing process, and adopts the characteristics of automatic slurry suction pipe, aerated agitation, sp...
