Waste liquid treatment device in PCB (printed circuit board) production process

Abstract

The invention discloses a waste liquid treatment device in a PCB production process, and relates to the technical field of electronic science and technology. The device comprises a supporting base, a preliminary filtering part, a stirring mechanism and a secondary filtering part. The preliminary filtering part is placed on the supporting base; the stirring mechanism is in pipeline connection with the preliminary filtering part; the stirring mechanism is in sliding connection with the secondary filtering part; and the secondary filtering part is in sliding connection with the supporting base. The preliminary filtering part comprises a filtering piece, a replacing part and a water pumping part. The top of the replacing part is slidably connected with the filtering piece, and the bottom of the replacing part is slidably connected with the water pumping part. The secondary filtering part is provided with filtering boxes, one side of each filtering box is fixedly connected with a fifth water outlet piece, and the other side of each filtering box is fixedly connected with a first water inlet piece. By arranging the primary filtering part and the secondary filtering part, during use, copper in waste liquid can be removed, and waste of copper is reduced. By arranging the two filtering boxes, the filtering boxes can be quickly and conveniently replaced when many precipitates exist in the filtering boxes.

Description

technical field [0001] The invention belongs to the technical field of electronic technology, and in particular relates to a waste liquid treatment device in the PCB production process. Background technique [0002] The waste liquid treatment device in the PCB production process, as the name suggests, is a device used in the PCB circuit board production process that can process waste liquid, although the existing waste liquid treatment device in the PCB production process can be used in the process To deal with the impurities in the waste liquid, so that the waste liquid is not polluting, but the existing equipment cannot observe the blockage of the mesh on the filter screen when processing the waste liquid, so that the reaction precipitation cannot be processed in time, and at the same time It does not have the function of collecting copper in waste liquid.

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a waste liquid treatment device in the PCB production process. By setting the primary filter part and the secondary filter part, copper can be recovered more efficiently and waste liquid reaction precipitation can be treated more conveniently, which solves the existing problems in During the process of use, the waste liquid settles to block the filter screen and the efficiency of copper recovery is not high.
