Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0036] Such as figure 1 and figure 2 As shown, the jet cavitation agitator of the present invention includes a fixed blade 2, a swirl blade 3 and a motor 5, the motor 5 is installed on the motor base 4, the motor 5 is connected to one end of the shaft 7, and the The other end of the shaft 7 is supported on the base 1, and several fixed blades 2 are uniformly distributed in the circumferential direction between the base 1 and the motor seat 4, and a plurality of swirl blades 3 are evenly distributed on the shaft 7 in the circumferential direction, and the swirl blades 3 are rotated Swept stationary blade 2 for forming cavitation zone I and jet flow zone. The swirl blades 3 are evenly distributed along the axial direction of the shaft 7, and are fixed on the shaft 7 by t...

Abstract

The invention provides a jet cavitation stirrer which comprises fixed blades, swirl blades and a motor, the motor is installed on a motor base, the motor is connected with one end of a shaft, the other end of the shaft is supported on a base, the multiple fixed blades are evenly distributed between the base and the motor base in the circumferential direction, and the multiple swirl blades are evenly distributed on the shaft in the circumferential direction. And the fixed blades are swept through the rotating swirl blades, so that a cavitation area and a jet flow area are formed. Each swirl blade comprises a pressure surface, a suction surface and an outer circular surface, and the outer circular surface is used for forming the jet flow area when sweeping to the fixed blades; when the suction surface sweeps to the fixed blades, the cavitation area is formed; and the pressure surface is used for providing power for medium flowing. A low-pressure area is formed through the combined actionof the rotational swirl blades and the fixed blades, meanwhile, a jet flow is formed at a gap between the two blades, cavitation is intensified, and organic pollutants in sewage are efficiently treated and degraded.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a jet cavitation mixer. Background technique [0002] With the continuous development of modern industries such as pharmaceuticals, chemicals, printing and dyeing, the artificially synthesized macromolecular organic matter and refractory chemical substances in water bodies are increasing year by year, making it difficult for traditional sewage treatment methods to adapt to the current increasingly stringent environmental protection requirements. The advantages of cavitation to degrade organic pollutants are reflected. [0003] Hydrodynamic cavitation is a hydrodynamic phenomenon. The local high temperature and high pressure, luminescence, discharge, strong shock wave, high-speed jet and other extreme conditions provided by the cavitation bubbles in the liquid during the movement and collapse of the hydrodynamic cavitation process can strengthen the physical and chemical processes...
