Mechanical acceleration settling tank

Abstract

The invention discloses a mechanical acceleration settling tank. Relates to the technical field of water treatment equipment. The structure is reasonable, the mixing effect of chemicals and water is good, and the settling effect can be improved. Comprising a tank body, a stirring mechanism, a water inlet pipe, a water outlet pipe and a blow-off pipe are arranged in the tank body, the stirring mechanism is driven by a motor, a chemical mixing device is arranged on the front portion of the water inlet pipe, the chemical mixing device comprises a chemical mixing chamber, an input pipe is arranged on the upper portion of one side of the chemical mixing chamber, and the water inlet pipe is communicated with the lower portion of the other side of the chemical mixing chamber; a bowl-shaped fixing cover is arranged on the inner wall of the input pipe, a gap exists between the arc portion of the fixing cover and the inner wall of the input pipe, and the opening portion of the fixing cover is attached to the inner wall of the input pipe. A medicine adding pipe penetrates through the input pipe and extends into the fixing cover, a medicine spraying nozzle is arranged on the side, located in the fixing cover, of the medicine adding pipe, and the medicine spraying nozzle sprays medicine towards the inlet direction of the input pipe.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a mechanically accelerated sedimentation tank. Background technique [0002] At present, the process of removing suspended particles in water by coagulation and sedimentation includes three stages: mixing of water and chemicals, reaction and separation of flocs and water. Special form of facility. The working principle of the sedimentation tank is: the raw water flows from the bottom to the top in the sedimentation tank, and there is a layer of suspended sludge in the sedimentation tank. When the small flocs formed by the action of the suspended particles and the coagulant pass through the mud layer with the water flow, the relatively large mud layer is adsorbed on the surface of the mud particles and quickly removed by contacting and colliding with the relatively large mud layer during the movement. The water is cleared; the clear water is collected and disch...

Problems solved by technology

[0003] At present, the mixing of medicament and water is generally to put the medicament directly into the settling tank. After running, it is found that the settling effect is not ideal, and the water quality after settling is poor.

The main reason is that the mixing time of the medicament and water is short, and it is difficult to achieve sufficient mixing of the two through a single pipeline, resulting in poor sedimentation effect
