A metal heat treatment sewage treatment system

Abstract

The invention relates to the field of sewage treatment, in particular to a metal heat treatment sewage treatment system. The first discharge tooth segment meshes with the first filter plate gear, so that the filter plate gear and the filter press plate rise, and the filter press plate tilts to the left under the action of its own gravity, and the rear second discharge tooth and the second filter plate The teeth mesh to change the meshing position of the discharge gear and the filter plate gear, so that the leftward tilt angle of the filter press plate under the action of its own gravity at this time becomes larger. After the filter plate is at the highest position and vertical, the second discharge tooth section and the second filter plate gear continue to engage, so that the filter plate gear and the filter plate will descend, and the filter plate will move to the right under the action of its own gravity. Tilting, the rear first unloading tooth segment meshes with the first filter plate teeth to change the meshing position of the unloading gear and the filter plate gear again, so that the filter press plate at this time tilts to the right under the action of its own gravity The angle becomes larger, thereby improving the automatic cleaning ability of the pressure equipment and improving the filtration efficiency.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a metal heat treatment sewage treatment system. Background technique [0002] In the process of metal heat treatment, a large amount of production sewage will be produced. The sewage not only contains large particles of impurities such as metal debris, but also contains harmful substances mixed into the water by other processes. This part of sewage needs to be discharged regularly, which not only causes waste of water resources, but also pollutes the environment due to the harmful substances contained in it. [0003] Therefore, it is necessary to filter the sewage generated during the metal heat treatment process. In the process of dumping filter residues in the existing filter equipment, the inclination angle of the filter plate is small, and the filter residue in the filter plate cannot be completely cleaned out. For the filter residue that cannot be cleaned Manual processing i...
