Dye production industrial sewage treatment equipment for removing heavy metals

Abstract

The invention discloses dye production industrial sewage treatment equipment for removing heavy metals. The equipment comprises a support seat, wherein an inner cavity is formed in the support seat, the upper wall of the inner cavity communicates with a feeding port with an upward opening, the upper wall of the inner cavity is fixedly connected with a filtering box, a filtering cavity which is through up and down and provided with a leftward opening is formed in the filtering box, a filter screen is fixedly connected to the lower wall of the filtering cavity, a sliding plate sliding left and right is arranged on the filter screen, and a temporary storage cavity penetrating up and down is formed in the sliding plate. According to the present invention, a stirring roller can be indirectly controlled to slowly rotate through the meshing of an inner gear and an outer gear, such that heavy metals in sewage can completely react with a heavy metal capturing agent so as to indirectly shift a spherical valve through a rotating block, sewage flowing is blocked, and the heavy metal precipitation effect is enhanced; and a flow limiting valve is matched with a torsional spring, so that feedingof the heavy metal trapping agent is controlled, and solvent waste is avoided.

Description

technical field [0001] The invention relates to the related field of industrial sewage treatment equipment, in particular to industrial sewage treatment equipment for dye production used to remove heavy metals. Background technique [0002] At present, industrialization in various fields is developing rapidly, and a large amount of industrial sewage will be produced in the process of industrial production. Before the sewage is discharged, it needs to be purified to reduce the pollution of water quality. For example, the sewage produced after dye production contains more heavy metals. Heavy metals cause great harm to the ecological environment and human health. However, the existing sewage treatment equipment has a simple structure. The chemical precipitation method is mainly used to separate the heavy metals in the sewage. It cannot fully react with the precipitating agent, and only part of the heavy metals in the sewage can be removed. The dye production industrial sewage t...

[0002] At present, industrialization in various fields is developing rapidly, and a large amount of industrial sewage will be produced in the process of industrial production. Before the sewage is discharged, it needs to be purified to reduce the pollution of water quality. For example, the sewage produced after dye production contains more heavy metals. Heavy metals cause great harm to the ecological environment and human health. However, the existing sewage treatment equipment has a simple structure. The chemical precipitation method is mainly used to separate the heavy metals in the sewage. Unable to fully react with the precipitating agent, resulting in only a part of the heavy metals in the sewage can be removed, a kind of dye production industrial sewage treatment equipment for removing heavy metals described in the present invention can solve the above problems
