Air flotation tank decontamination device in leather sewage treatment

Abstract

The invention discloses an air floatation tank decontamination device for leather sewage treatment. The air floatation tank decontamination device structurally comprises a tank body, a clean water slot, a sewage slot, a movable guide rail, a decontamination tank and a filtering lifting cage, wherein a support angle iron, a motor bracket, a motor, a motor vibration damping plate and a speed reducerare arranged in the tank body, a clean water flow guide channel, a clean water filter net are arranged in the clean water slot, a sewage treatment channel and a sewage filter net are arranged in thesewage slot, and the filtering lifting cage is provided with a bottom fixed block and a residue discharging door. When the air floatation tank decontamination device is used, the filtering lifting cage can be controlled by the motor so as to fish garbage in the decontamination tank, impurities remained in the sewage can be filtered twice by virtue of the sewage treatment channel and the clean water flow guide channel, filtered clean water can be guided into the decontamination tank, and the sewage can be recycled, so that the water resource is saved, meanwhile, the time and the labor can be saved, and the air floatation tank decontamination device is simple in construction and convenient to use.

Description

technical field [0001] The invention relates to a decontamination device for an air flotation tank in leather sewage treatment, belonging to the field of decontamination devices. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning.
