Electroplating wastewater integrated dosing system

Abstract

The invention discloses an electroplating wastewater integrated dosing system, and belongs to the field of dosing equipment. The electroplating wastewater integrated dosing system comprises a plurality of chemical storage tanks, an air pump, an air pipe, stirring mechanisms, circulating pipelines, dosing pipelines, metering pumps, electromagnetic flowmeters, diaphragm regulating valves and rotor flowmeters which are connected with one another, wherein each chemical storage tank is provided with a stirring mechanism, the air pumps supply air to all the stirring mechanisms through the air pipe,the medicine outlet of each chemical storage tank is fixedly communicated with a circulating pipeline, each circulating pipeline is provided with a metering pump, and each circulating pipeline is fixedly communicated with a plurality of dosing pipelines, and an electromagnetic flowmeter, a diaphragm regulating valve and a rotor flowmeter are sequentially arranged on each dosing pipeline along theflow direction of the liquid. The electroplating wastewater integrated dosing system is integrally arranged and convenient to manage, only one metering pump is needed for a plurality of dosing points,and liquid medicine precipitation is effectively avoided.

Description

technical field [0001] The invention belongs to the field of dosing equipment, in particular to an integrated dosing system for electroplating wastewater. Background technique [0002] The sources of electroplating wastewater are generally: (1) plating cleaning water; (2) waste electroplating solution; (3) other wastewater, including washing the floor of the workshop, scrubbing plate washing water, condensed water from ventilation equipment, and leakage from plating tanks. Or various tank liquids and drainages of "running, popping, dripping, and leaking" caused by improper operation and management; (4) Equipment cooling water, which has not been polluted except for the temperature rise during use. The water quality and quantity of electroplating wastewater are related to the process conditions of electroplating production, production load, operation management and water use methods and other factors. The water quality of electroplating wastewater is complex and its composit...

AI Technical Summary

Problems solved by technology

The water quality of electroplating wastewater is complex, and its composition is difficult to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver, and cyanide, and some are highly toxic substances that are carcinogenic, teratogenic, and mutagenic.

[0003] The existing dosing systems for electroplating wastewater are mostly point-to-point dosing, and each dosing point needs to be equipped with a metering pump. When multiple dosing is required, a large number of metering pumps are required; The medicine tanks are scattered, which is not easy to manage; the medicines in the medicine storage tanks are also deposited for a long time, which not only easily causes pipeline blockage, but also affects the use effect
