Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, process system of the present utility model, it includes chrome-plating bath 1 and rinsing bowl 2, and it also includes wastewater collection pond 3, chromium water separator 5 and cistern 6；Described chrome-plating bath 1 is provided with chrome-plating bath water injector 11 and chrome-plating bath dashpot 12, and its chrome-plating bath water injector 11 is connected with DI；It is provided with flusher in described rinsing bowl 2, its flusher is connected with DI, its flusher includes rinsing bowl water spout 21 and multi-level water spray mouth 22, its rinsing bowl water spout 21 is positioned at rinsing bowl 2 upper end, its multi-level water spray mouth 22 is positioned in the middle part of rinsing bowl 2, and rinsing bowl 2 is connected with wastewater collection pond 3 by pipeline；Described wastewater collection pond 3 is connected with chromium water separator 5 by pipeline, and chromium water separator 5 is connected with chrome-plating bath dashpot 12 and cistern 6 respectively also by pipeline.Described wastewater collection pond 3 is externally provided with spillway basin 4, is connected by pipeline between wastewater collection pond 3 with spillway basin 4.Described spillway basin 4 is externally provided with chrome waste water collecting pit 7, is connected by pipeline between spillway basin 4 chrome waste water collecting pit 7.Described rinsing bowl 2 is externally provided with manual cleaning loading area 8, and manual cleaning loading area 8 is connected with DI, and its manual cleaning loading area 8 is connected with chrome waste water collecting pit 7 also by pipeline.Described wastewater collection pond 3 is connected with DI also by pipeline.
In using, chrome-plating bath water injector 11 and flusher are connected with DI, sprinkler part to guarantee chrome-plating bath 1 and rinsing bowl 2 has sufficient water source to be rinsed workpiece, chrome-plating bath dashpot 12 and chrome-plating bath 1 are connected with each other by circulating line, can ensure that the chromium-containing solution in chrome-plating bath dashpot 12 supplements in time in chrome-plating bath 1.After having been plated in chrome-plating bath 1 by workpiece, it is proposed to during chrome-plating bath 1, opening top layer chrome-plating bath water injector 11, with pure water, workpiece is carried out first rinse, workpiece promotes closes chrome-plating bath water injector 11 when terminating；After put the workpiece in rinsing bowl 2 clean, this groove top layer rinsing bowl water spout 21 is opened in putting into workpiece fabrication, with pure water, workpiece is carried out pre-flush, when workpiece is put into after in groove, close top layer rinsing bowl water spout 21, open the multi-level water spray mouth 22 in rinsing bowl 2, with pure water, workpiece is repeatedly rinsed, it is ensured that each orientation of workpiece is all flushed to.Flushing terminates rear lifting workpieces, is now again turned on top layer water spout 21, with pure water, workpiece is finally rinsed；Rinsing bowl 2 rinses the waste water of workpiece and enters wastewater collection pond 3 through pipeline；Chromium water separator 5 extracts chromate waste water by pipeline from wastewater collection pond 3, then chromate waste water is carried out vacuum distillation process, and the pure water of generation is discharged in cistern 6 by pipeline and stores；Clear water in cistern 6 can also be pipelined in wastewater collection pond 3, recycles as pre-flush water to rinsing bowl 2 again through pipeline transportation.When the chromate waste water of the internal distillation of chromium water separator 5 reaches normal concentration, this chromium-containing solution is pumped by pipeline and returns to recycling in chrome-plating bath dashpot 12.Workpiece is carried out last artificial flushing to manual cleaning loading area 8 by the workpiece transfer after rinsing bowl flushing, clean to guarantee the poisonous chromate waste water cleaning down on workpiece；A small amount of waste water that overflows in wastewater collection pond 3 enters into spillway basin 4, and water wasting and a small amount of waste water of manual cleaning loading area 8 artificial flushing in spillway basin 4 are transported to chrome waste water collecting pit 7 each through pipeline, is pumped to Sewage Disposal then through water pump and processes.
