Abstract

The invention provides a separating and drying device for preparing basic cupric carbonate from copper-containing etching waste liquid, and relates to the field of basic cupric carbonate separating and drying devices. The separating and drying device for preparing the basic cupric carbonate from the copper-containing etching waste liquid comprises a drying box, wherein a stirring rod is rotationally connected to the upper middle portion in the drying box, the other end of the stirring rod penetrates through the side wall of the other side of the drying box and is rotationally connected to one side of the upper portion of a T-shaped tube, and a spiral feeder is arranged in the middle of the lower end in the drying box; a feeding tube penetrates through the lower portion of the outer wall of the other side of the drying box, a coil is arranged on the periphery of the middle of the feeding tube, a temperature sensor is arranged on the outer wall of the middle of the front end of the feeding tube, a material plate is fixedly connected to the top end of a hydraulic cylinder, and the material plate is arranged in the vacuum box in a sliding mode. And through matched use of the drying box, the spiral feeder, the feeding tube, the vacuum box and the coil, the drying cost is saved, the drying efficiency is improved, and the device is worthy of being vigorously popularized.

Description

technical field [0001] The invention relates to the technical field of separation and drying devices for basic copper carbonate, in particular to a separation and drying device for preparing basic copper carbonate from copper-containing etching waste liquid. Background technique [0002] Copper etching solution is suitable for the etching of copper on printed boards. The etching speed is fast and the waste liquid recovery is simple. It is widely used in printed boards or circuit boards. After the copper etching liquid is etched, it becomes waste liquid, which contains copper ions and can be used for preparation Basic copper carbonate, after the successful preparation of basic copper carbonate, it needs to be separated and dried. [0003] When drying the basic copper carbonate after separation, the cost of drying is often very high, but the drying effect is not ideal. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of t...
