Waste liquid treatment device used after steel slag treatment

Abstract

The invention discloses a waste liquid treatment device used after steel slag treatment. The waste liquid treatment device comprises a water tank, a water outlet pipe installed on the water tank and a filter box body fixed to the water tank through a support. According to the device, an electric push rod drives a moving plate to move, after a connecting cover is in butt joint with a second rectangular block, a screw rod rotates in the process that a motor drives a first transmission shaft to rotate, the screw rod is used for butt joint of a flange and a connecting disc, hot air flow generated by a heat pump enters the interior of a filtering box through an air outlet pipe, and fine particles can be dried; under the action of a rotating arm and a touch piece, accumulation of fine particles on a first filter screen can be avoided, drying of the fine particles is facilitated, along with increase of airflow, the dried fine particles enter a collecting shell through a connecting pipe, and under the action of a second filter screen, the fine particles are collected in the collecting shell, so that the collecting effect is improved. Compared with a wastewater treatment device in the prior art, fine particles can be collected in time, so that subsequent wastewater treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of steel slag waste liquid treatment, in particular to a waste liquid treatment device for steel slag treatment. Background technique [0002] At present, steel slag is generally discarded as waste after simple treatment, which not only causes waste of resources, but also imposes a burden on environmental protection. In order to make full use of the steel slag, a steel slag processing system is disclosed in the prior art, that is, a mill and a shaker are used for processing. [0003] Mills and shaking tables will produce wastewater containing fine particles during the treatment process. If the wastewater is directly discharged to the external environment, it will still have an impact on the environment. In the prior art, the wastewater is usually discharged by filtering, but in the long run During the use of time, fine particles are easy to accumulate on the filter screen. If the fine particles are not clea...

[0003] Mills and shaking tables will produce wastewater containing fine particles during the treatment process. If the wastewater is directly discharged to the external environment, it will still have an impact on the environment. In the prior art, the wastewater is usually discharged by filtering, but in the long run During the use of time, fine particles are easy to accumulate on the filter screen. If the fine particles are not cleaned in time, it is easy to affect the discharge of subsequent wastewater.
