Automatic liquid-state preparation and feeding system for dense medium particles

Abstract

The invention discloses an automatic liquid-state preparation and addition system for dense medium particles. The system comprises a dense medium suspension preparation box and a dense medium powder bin, an opening in the top of the dense medium turbid liquid preparation box is connected with a moisture-proof conveyor and a backflow pipeline, the backflow pipeline is connected with a conveying pipeline, a turbid liquid feeding door and a turbid liquid feeding flowmeter are arranged on the conveying pipeline, and a turbid liquid mass density meter and a turbid liquid backflow adjusting door are arranged on the backflow pipeline; a preparation box liquid level meter is arranged at the bottom of the side wall of the dense medium suspension preparation box; the preparation box water inlet door, the preparation box liquid level meter and the like are all connected with the controller. The device can effectively reduce pollution and blockage of heavy medium particles to equipment in the feeding process, greatly improve the utilization efficiency of the heavy medium particles, accurately control the preparation concentration and the feeding amount of the heavy medium turbid liquid, accurately control the concentration of suspended matters in the heavy medium coagulation clarification reactor, realize automatic control in the preparation and feeding process, and reduce the production cost. And system operation is stable and reliable.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to an automatic liquid preparation and dosing system for heavy medium particles. Background technique [0002] Dense medium flocculation technology is to add particles or powders with larger specific gravity into the coagulation equipment, and through stirring and water flow mixing, the dense medium particles and the flocs produced by the softening and coagulation reactions are fully contacted and mixed, and the flocs are in this process. The heavy medium particles are gradually wrapped in the middle, and the heavy medium particles have a downward drag on the sludge flocs, which increases the sedimentation speed of the sludge. The above process can ensure the water quality of the effluent of the equipment while improving the rising flow rate of the equipment, increase the sedimentation efficiency of the equipment, and improve the treated water volume of the equipment per u...
