Centralized recovery processing equipment for copper powder of multiple circuit board surface brushing machines

Abstract

The invention discloses centralized recovery processing equipment for copper powder of multiple circuit board surface brushing machines. Copper-containing wastewater produced by the washing and brushing sections of multiple circuit board surface brushing machines converges and flows into a first pipe and then into a copper powder sedimentation basin through the first pipe; the copper-containing wastewater naturally settles in the copper powder sedimentation basin, and copper powder settles in the bottom of the copper powder sedimentation basin; with the increase of the copper-containing wastewater, the upper part of the copper powder sedimentation basin is relatively clear while the liquid containing copper powder floatage overflows from an overflow port and flows into a pressure filter to be subject to pressure filtering; the pressure filter presses the copper powder floatage into filter cakes and recovers the filter cakes; and the clear water filtered by the pressure filter flows into an overflow water centralization basin, and the clear water in the overflow centralization basin is returned to the washing and brushing sections of the circuit board surface brushing machines to be reused. Circularly used in the such way, the centralized recovery processing equipment for copper powder of multiple circuit board surface brushing machines has the advantages that the cost and labor are saved, the production efficiency and quality are improved and simple structure, low cost and easy implementation are ensured.

Description

technical field [0001] The invention relates to an improvement of copper powder recovery equipment in a PCB manufacturing process, in particular to a copper powder centralized recovery treatment equipment of multiple circuit board surface brushing machines which can save manpower, reduce costs and improve quality. Background technique [0002] The copper powder produced during the production and operation of multiple circuit board surface brushing machines is collected by an independent copper powder recycling machine. Copper powder is filtered out by the recovery filter bag, and the water is returned to the brushing section through the copper powder recovery machine. The used water is discharged to the wastewater treatment plant for treatment after several cycles. In this way, the filter bags are replaced frequently, the maintenance frequency is too high, and the copper powder filtration effect is poor, which affects the production line efficiency and product quality. At th...

Problems solved by technology

In this way, the filter bags are replaced frequently, the maintenance frequency is too high, and the copper powder filtration effect is poor, which affects the efficiency of the production line and product quality. At the same time, special personnel are required to be responsible for maintenance and cleaning during the day and night shifts, which wastes manpower and results in higher wastewater treatment costs. high
