Abstract
The invention relates to an electroplating-rinse-water recycling and reusing device. The device comprises a reflux tank (2), a pipeline (6) and a water suction pump (4). The pipeline (6) is disposed at a position of the lower water level of a cleaning tank (8), and is communicated with the cleaning tank and a recycling tank. The water suction pump (4) is disposed between the reflux tank and an electroplating tank. According to the device, rinse water can be collected to be recycled and reused, thus saving the cost, and avoiding environment pollution and resource waste which are caused by discharging the rinse water containing heavy metal ions.
Description
Technical field
The invention belongs to the electroplating technology field, be specifically related to a kind of device of electroplating rinse water recycling.
Background technology
Electroplating, is to utilize electrolysis process, and metal or alloy is deposited on to the plating piece surface, forms the process for treating surface of metal plating.At present, in known Electroplating Production, when plating piece leaves coating bath, the plating piece surface can adhere to the drag-out in coating bath.The ordinary method of cleaning plating piece surface band fluid is to use a large amount of rinse water to carry out three stage countercurrent cleanings, contains the contained heavy metal ion of a large amount of electroplating solutions in the rinse water after cleaning.Disposing the rinse water customary way is it to be entered to waste water processing station carry out chemical treatment, and this treatment process cost is high, resource utilization is low, the wastewater treatment rate is low, and always some heavy metal ion can enter the outside contamination environment.
Summary of the invention
For solving the problem of electroplate rinsing water treatment in Buddha's warrior attendant line of cut production process, the invention provides a kind of electroplate rinsing water reflux trough of collecting and can be recycled, this backflash can carry out plating piece after rinse water that eight stage countercurrent mattings produce reclaim heating in rinse bath, be back to the coating bath cycling and reutilization, avoided the discharge pollution on the environment of heavy metal ion in the waste of rinse water and rinse water.
Principle of the present invention is to increase a cell body---backflash at coating bath and rinse bath one side, utilizes the low level diversion, by pipeline, the rinse water that discharge in rinse bath are collected into to backflash.In coating bath, electroplate liquid is generally to need heating, and heating evaporation causes plating solution solute relative content to raise, and for solute, reduction plating solution drag-out in the balance plating solution, need to add water and keep liquid level normal.Backflash and coating bath link, and when in coating bath, liquid level needs balance, lift pump enters coating bath by the rinse water that reclaim in backflash, and the magnitude of recruitment of secondary rinse water just in time can be used as the cell body make up water and makes up the plating solution steam output.After rinse water are refluxed the groove recycling, just avoided heavy metal ions in wastewater Cu
2+, Zn
2+Discharge, also greatly dwindled cost for wastewater treatment when having contained environmental pollution, take full advantage of the auxiliary material resource.
Concrete technical scheme is as follows: a kind of electroplating rinse water recycling device, by backflash, pipeline and lift pump, formed, and pipeline is located at the low-water level place of rinse bath, is communicated with rinse bath and accumulator tank, and lift pump is arranged between backflash and coating bath.
In above-mentioned electroplating rinse water recycling device, described backflash also has heating and temperature-control device.
Retrieving arrangement of the present invention is applied to Buddha's warrior attendant line of cut production process, by collecting rinse water, carries out recycle.Can avoid, because of the rinse water that discharge contains heavy metal ion, environment is produced to pollution, the wasting of resources, cost-saving.
The accompanying drawing explanation
Fig. 1 is the schematic diagram that retrieving arrangement of the present invention is connected with electroplating assembly line.
1. plating pieces in figure, 2. backflash, 3. coating bath, 4. lift pump, 5. rinse water, 6. pipeline, 7. rinse water, 8. rinse bath.
Embodiment
In Fig. 1, plating piece 1 moves from left to right, enter rinse bath 8 after leaving coating bath 3, rinse bath adopts eight stage countercurrent washing out methods, use rinse water 7 step by step to the plating piece 1 appended plating solution rinsing in top layer, the rinse water 5 that produce after rinsing, along with the pipeline 6 of guiding backflash 2 into is recycled to backflash 2, after by heating, the rinse water 5 that reclaim being carried out to temperature control, are controlled lift pump 4 rinse water 5 in backflash 2 are entered to coating bath 3.In coating bath, electroplate liquid is because heating evaporation, and solvent reduces, and need to add water and keep liquid level normal, and the rinse water quantity discharged after recovery just can be used as coating bath and makes up the continual supply that circulates of plating solution steam output, balance liquid level.Simultaneously, also avoided heavy metal ion Cu in rinse water
2+, Zn
2+Discharge cause environmental pollution.
Claims (2)
