Abstract
The invention publics a kind of process that results in electroplating automation line without taping rinsing water, of which the key point is: 1. when electroplated block slips down from the plating bath to the recovery flute, let micro atomization waterjet unit using water jet water mist to clean electroplated block, let the mass of water from micro atomization waterjet unit equals evaporation capacity of electropaing bath in plating bath in unit time. 2. Supply recovery succus in the recovery tank to the plating bath; the unit is for the technology. The feature is: between plating bath and rinse tank is recovery tank, each segment is connected with pipelines and pumps, and for recovery tank and rinse tank micro atomization waterjet units are located on both nicks. The invention is for all plating technology. The energy saving tech is of less cost and less pollution.
Description
Technical field
The present invention relates to a kind of technology and device thereof that the back is cleaned plated item of electroplating, particularly relate to and a kind ofly plated item is carried out technology and the device thereof that water smoke curtain mode is cleaned with minor amount of water.
Background technology
In plating production process, need the plated item surface after the electroplating processes is cleaned, to reach the purpose of cleaning the residual electroplate liquid of piece surface.At present the multiple tracks washing out method that adopts comprises the steps: that mainly (1) part inserts a rinse bath that fills stationary water, the most of residual electroplate liquid of part flush away piece surface in first rinse bath after plating tank carries out electroplating processes.Can setting up fully again according to the situation of cleaning, 1-2 rinse bath that fills stationary water cleans; (2) through after 2-3 cleaning of stationary water, the rinse bath that part enters flowing water cleans, and process can reach the residual electroplate liquid of cleaning piece surface in the cleaning of the rinse bath of 1-2 time flowing water.For reducing water consumption and the environmental pollution in this electroplating cleaning technique process, can adopt and return plating tank after first solution of containing the rinse bath of stationary water handled by evaporation concentration, when answering electroplating processes in the plating tank to replenish because of the damaged solution amount of evaporation.Thisly utilize first solution of containing the rinse bath of stationary water to replenish the plating tank water evaporates and during damaged solution amount, evaporation moisture content is few when handling because of plating tank, and first rinse bath solution amount of containing stationary water is many, the concentration of the rinse bath solution of first Sheng stationary water is more and more higher in the process of constantly cleaning, influence the cleaning performance of piece surface, increased the difficulty that back road cleans, can only guarantee to electroplate cleaning requirement with strengthening the clear water amount and increasing rinse bath quantity.So present multiple tracks method electroplating cleaning technique energy consumption is big, resource consumption is many, the production cost height.
Summary of the invention
The objective of the invention is to overcome the deficiency that existing electroplating cleaning technique exists, a kind of energy-saving and environmental protection, electroplating cleaning technique that production cost is low are provided; Another object of the present invention provides a kind of device of realizing this technology.
The technical scheme that the present invention takes: a kind of electroplating cleaning technique, it is characterized in that following steps: elder generation was through reclaiming dead slot before one, plated item entered rinse bath from plating tank, with the microatomization water jet device plated item water spray curtain is cleaned, the described microatomization water jet device injection water yield is identical with the steam output cardinal principle of electroplate liquid in the interior described plating tank of unit time in the control unit time; Two, the recovery liquid in the described recovery dead slot is added in the described plating tank.
Temperature of electroplating solution is more than or equal to 45 ℃ in the described plating tank, and controlling every meter injection of described microatomization water jet device water yield is 300～350ml.
Described microatomization water jet device sprays plated item under last with the angle of 30 ° in level of incline face, and the height of control water smoke curtain is 10cm.
A kind of device of realizing above-mentioned electroplating cleaning technique, comprise plating tank and a plurality of rinse bath on the plating automatic line, it is characterized in that being equipped with between plating tank and the rinse bath recovery dead slot, described plating tank, rinse bath and recovery dead slot are connected with pump by pipeline, and described recovery dead slot is equipped with at least one pair of microatomization water jet device in the notch both sides.
Beneficial effect of the present invention is, most drag-out on the plated item can be reclaimed the liquid form with high density by electroplating cleaning technique of the present invention recycles, thereby 2～3 roads that reduced the back reclaim matting: because this amount and bath solution evaporation consumption of reclaiming liquid concentration height, recovery liquid are basic identical, therefore need not to adopt the evaporation concentration operation, but the thickening equipment of conserve expensive and the operation that simplifies the operation; Because but most of drag-out direct reuse of electroplating is taken liquid measure out of and significantly reduced, therefore the waste strength to discharging is very low, has reduced the wastewater treatment expense; The present invention is suitable for any electroplating technology, is a kind of energy-saving and environmental protection, electroplating cleaning technique that production cost is low.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail: as shown in Figure 1, the present invention is plating tank 1 back at plating automatic line, the front of rinse bath 3 is provided with a high efficiente callback dead slot 2 earlier, do not irritate rinse water in the described recovery dead slot 2, at the bilateral that reclaims dead slot 2 notches, microatomization water jet device 4 is installed, after taking out from plating tank 1, plated item enters when reclaiming dead slot 2 and making down maneuver, water in microatomization spray apparatus 4 usefulness back accumulator tanks or the rinse bath 3 is facing to the form of plated item surface with the water smoke curtain, 30 ° in level of incline face sprays plated item from the lower end to the upper end, the height of water smoke curtain is 10cm, and the down maneuver of plated item is automatically performed by the driving on the plating automatic line.By this step, this can splash into the bottom of sky accumulator tank 2 with the recovery liquid form of high density with the drag-out more than 97% on the plated item, and this reclaims liquid can not need evaporation concentration and directly be supplemented in the plating tank 1 of front.When the bath solution temperature more than 45 ℃, reclaiming dead slot 2 average per 1 meter spraying water yield is 300～350ml, this water consumption and bath solution evaporation are basic identical, but this concentrated solution fully recovering is to plating tank.
As shown in Figure 2, a kind of device of realizing above-mentioned electroplating cleaning technique, comprise plating tank 1 and some rinse baths 3 on the plating automatic line, it is characterized in that being equipped with between plating tank 1 and the rinse bath 3 recovery dead slot 2, described plating tank 1, rinse bath 3 and recovery dead slot 2 are connected with pump by pipeline, and described recovery dead slot 2 is equipped with microatomization water jet device 4 in the notch both sides.
