Technical field
The present invention relates to the technical field of the recycling of silver in silver-containing liquid waste, the silver of a kind of silver-containing liquid waste returns
Receiving apparatus.
Background technology
At present, in the useless shadow liquid in photo industry and the COD analysis in laboratory and other silver-containing liquid waste
Argent reclaim, some employing generates sulphide precipitation and the various improvement sides that are derived on the basis of method thereof
Method, but there is the shortcoming being difficult to overcome in said method, and the sulfide precipitation i.e. generated to release substantial amounts of SO2 when calcination
Gas, causes the severe contamination to environment, and is mingled with too many in precipitating, and hinders the gathering caking of silver when calcination, often needs
Want secondary separation secondary calcination, both wasted the energy, easily cause again the loss of silver.Also there is use chemical method, such as, use iron plate straight
Connecing reduction, C, the Si etc. in iron plate can enter argentum powder and make subsequent treatment hard to tackle, use sodium sulfide high temperature reduction method, need
Little iron furnace melting, is generally unsuitable for the waste water that treating capacity is few, in the sodium sulfide sedimentation method, reduces de-according to hydrochloric acid and iron plate
Sulfur, this is not only reduced directly many one formalities than iron plate, and due to a solid liquid phase reactor, processes the most loaded down with trivial details.
Electrolysis is a kind of commonly used method reclaiming silver, and the anion that electrolysis produces shifts to anode stub, electrolysis
The electrolytic silver produced is attached to cathode bar, after electrolysis is fully completed, needs electrolyte is given off electrolysis bath, subsequently enters de-
Silver station, existing stripping silver method generally uses manually to be peeled off, but silver being attached on cathode bar tightly, it is difficult to it
Taking off, this increases the labor intensity of workman beyond doubt.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of compact conformation, silver recovery efficiency is high, can
Electrolytic silver on graphite rod is quickly peeled off, is alleviated the silver recovery unit of the silver-containing liquid waste of labor strength.
The purpose of the present invention is achieved through the following technical solutions: the silver recovery unit of a kind of silver-containing liquid waste, and it includes work
Station, the riser being arranged on workbench, electrolysis bath and water pump, the motor being arranged on riser and screw mandrel, described screw mandrel hangs down
To setting, the upper end of screw mandrel is connected with the outfan of motor, and screw mandrel connects nut, and the left part of nut is installed with
The cylinder of vertical setting, the bottom of the piston rod of cylinder connects scraper, in described electrolysis bath and be positioned at the end table of electrolysis bath
It is provided with two rolling bearings on face, in the inner ring of two rolling bearings, is fitted with graphite rod A and graphite rod B, graphite rod B respectively
Being positioned at the lower section of scraper, the sidewall of electrolysis bath is provided with inlet and liquid outlet, the water sucking mouth of water pump is connected with liquid outlet.
Described it also includes that controller, described controller are connected with cylinder, motor and water pump.
Described graphite rod A and the most vertical setting of graphite rod B.
Described riser is perpendicular to workbench and arranges.
Described liquid outlet is positioned at the lower section of inlet.
The invention have the advantages that silver recovery efficiency of the present invention is high, can quickly the electrolytic silver on graphite rod be shelled
From, alleviate labor strength.

Fig. 1 is the structural representation of the present invention；
In figure, 1-workbench, 2-riser, 3-electrolysis bath, 4-water pump, 5-motor, 6-screw mandrel, 7-nut, 8-cylinder, 9-scraper,
10-rolling bearing, 11-graphite rod A, 12-graphite rod B, 13-inlet, 14-liquid outlet.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to the following stated:
As it is shown in figure 1, the silver recovery unit of a kind of silver-containing liquid waste, it includes workbench 1, the riser 2 that is arranged on workbench 1,
Electrolysis bath 3 and water pump 4, the motor 5 being arranged on riser 2 and screw mandrel 6, riser 2 is perpendicular to workbench 1 and arranges, described screw mandrel 6
Vertical setting, the upper end of screw mandrel 6 is connected with the outfan of motor 5, and screw mandrel 6 connects nut 7, and the left part of nut 7 is solid
Dingan County is equipped with the cylinder 8 of vertical setting, and the bottom of the piston rod of cylinder 8 connects scraper 9.
As it is shown in figure 1, in electrolysis bath 3 and be positioned on the basal surface of electrolysis bath 3 and be provided with two rolling bearings 10, two rollings
Being fitted with graphite rod A11 and graphite rod B12 in the inner ring of dynamic bearing 10 respectively, therefore graphite rod A11 and graphite rod B12 all can be around
Own axes rotates, graphite rod A11 and the most vertical setting of graphite rod B12, and graphite rod B12 is positioned at the lower section of scraper 9, electricity
Solving and be provided with inlet 13 and liquid outlet 14 on the sidewall of groove 3, liquid outlet 14 is positioned at the lower section of inlet 13, the water suction of water pump 4
Mouth is connected with liquid outlet 14.
Described it also includes that controller, described controller are connected with cylinder 8, motor 5 and water pump 4, and workman can pass through
Controller controls stretching out or retracting of the piston rod of cylinder 8, can also control motor 5 and the startup of water pump 4 or pass by controller
Close, facilitate the operation of workman, therefore there is the feature that automaticity is high.
The job step of the present invention is:
