Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of wastewater treatment, and particularly relates to a wastewater treatment equipment for ore-dressing reagent production. BACKGROUND

[0002] Ore-dressing reagent is a chemical substance used for adjusting the physical and chemical properties of mineral surface and flotation medium in the mineral processing process, mainly including collectors, frothers, depressants, flocculants, regulators and the like. Ore-dressing wastewater mainly comes from the links of flotation, tailing treatment and equipment flushing in the ore-dressing process, and is characterized by large water quantity, high suspended matter content, fine particle size, multiple types of harmful pollutants, and a large amount of organic matter and heavy metal ions difficult to degrade. When treating the ore-dressing reagent wastewater, lime is usually added to the wastewater to produce metal precipitation, and then the precipitation is filtered through a filter screen. However, the existing wastewater treatment equipment is usually inconvenient for cleaning the metal precipitation on the surface of the filter screen, and the metal precipitation on the surface of the filter screen is distributed relatively dispersedly, which increases the difficulty of cleaning the metal precipitation on the surface of the filter screen and has certain limitations.

[0003] The Chinese utility model patent with the publication number CN216946536U discloses a treatment equipment for ore-dressing reagent production wastewater, which includes a treatment box, a filter screen, a water pump, a control motor B, a rotating shaft and a brush. When in use, the wastewater and lime are conveyed into the treatment box, the wastewater reacts with the lime to produce precipitation, the precipitation is hindered on the upper surface of the filter screen, and then the water pump is started to pump the wastewater out of the treatment box. When the precipitation accumulates too much, the control motor B is started to drive the brush to rotate through the rotating shaft, so as to stir the surface of the filter screen and reduce the blockage of the filter screen due to too much precipitation.

[0004] However, the stirring of the brush on the surface of the filter screen in the above scheme cannot well concentrate the treatment of the metal precipitation, and the metal precipitation is distributed relatively dispersedly, which makes it inconvenient for the operator to clean the accumulated metal precipitation on the surface of the filter screen, especially the metal precipitation in the deep part of the filter screen. Therefore, the collection and cleaning of the metal precipitation are difficult, which increases the workload of the operator and has certain limitations. UTILITY MODEL CONTENT
