Embodiment Construction

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Please refer Figure 1 to Figure 6 As shown, the present invention provides a mixing device 100, which includes a water inlet pipe 1, a drug addition pipe for inputting drugs, a lifting pump 3 for mixing drugs and wastewater into a mixed liquid, an intermediate pipe 4, and a A mixer 5 and a water outlet pipe 6 for mixing the mixed liquid. The wastewater passes through the water inlet pipe 1, the lift pump 3, the intermediate pipe 4, the mixer 5 and the water outlet pipe 6 in sequence.

[0020] Wherein, the water inlet pipe 1 and the dosing pipe 2 are in communication with the lift pump 3, specifically, both are in communication. The lift pump 3 is an ordinary pipeline pump or a corrosion-resistant pipeline pump with an impeller (not shown),...

Abstract

The invention provides a mixing device for wastewater treatment, characterized in that the mixing device includes a water inlet pipeline, a dosing pipeline for inputting medicine, a lifting pump for mixing medicine and wastewater into a mixed liquid, and an intermediate pipeline , a mixer and an outlet pipeline for fully mixing the mixed liquid, the water inlet pipeline communicates with the dosing pipeline and the lift pump, and the intermediate pipeline communicates with the lift pump and the mixer to The mixed liquid is input into the mixer; the lift pump is provided with an impeller. The mixing device of the present invention uses a lifting pump so that the medicine input from the dosing pipeline can be uniformly dispersed in a very short time, and is pre-mixed with the waste water entering from the water inlet pipeline to form a mixed solution; The mixed liquid is mixed more fully, and the mixing efficiency is improved.

Description

Technical field [0001] The invention relates to a mixing device, in particular to a mixing device with high mixing efficiency and sufficient mixing. Background technique [0002] Coagulation is an important process in the wastewater treatment process. It is a simple and economical method to improve water quality, including two processes of mixing and coagulation. Among them, mixing is very important, especially the length of mixing time will directly affect the effect of coagulation. This process requires the chemical agent to be uniformly dispersed in a very short time, usually within 1 second, and then the chemical agent and water are fully mixed. Mixed to form tiny flocs, thereby providing favorable conditions for flocculation. At present, the mixing operation generally uses mechanical stirring and mixing, but mechanical stirring cannot achieve the purpose of instantaneous uniform dispersion, which affects the full mixing of waste water and chemicals, thereby reducing the eff...
