The utility model discloses an electroplating effluent metal recycling system, including filter module, electrolysis module and the waste liquid storage jar that connects gradually, the electrolysis module includes the electrolysis jar, the electrolysis jar includes a plurality of electrolysis chambeies that communicate in proper order, and electrolysis chamber one end is provided with the negative pole current conducting plate, the other end is equipped with the positive pole current conducting plate, still include the ventilating mechanism that lets in the air to electrolysis chamber bottom, the inboard of positive pole current conducting plate and negative pole current conducting plate is equipped with recessed cambered surface, be equipped with at least one horizontally guide plate in the electrolysis chamber. The utility model discloses a multistage electrolytic mode, the metal recycling who effectively improves electroplating effluent is rateed, is particularly useful for in the middle of the large -scale electroplating sewage treatment.
Description
Technical field
The utility model relates to a kind of metallic wastewater treatment unit, is specifically related to a kind of electroplating wastewater metal recovery system.
Background technology
Plating is exactly the process utilizing electrolysis principle to plate other metal or alloy of skim on some metallic surface, be utilize electrolytic action to make the technique of the surface attachment layer of metal film of metal or other material thus play to prevent corrosion, improve the effects such as wear resistance, electroconductibility, reflective and having improved aesthetic appearance.In electroplating process, can produce the electroplating wastewater such as spent plating bath, plating piece rinse water, the water quality of electroplating wastewater is complicated, and it contains more heavy metal ion.At present, this kind of waste water of industrial process mainly adopts ion exchange method, electrolytic process, wherein electrolytic process is simple to operate, with low cost, efficiency is high, but existing electrolytic process metal recovery rate is lower, especially, when the concentration of metal ions in sewage thins out through electrolysis in early stage, the metal of ionic state is difficult to separate out on negative electrode again.
Utility model content
In view of this, the utility model discloses the high electroplating wastewater recovering system of a kind of metal recovery rate.
The purpose of this utility model is achieved through the following technical solutions: electroplating wastewater metal recovery system, and comprise the filtration module, electrolytic module and the waste liquid storage cylinder that connect successively, described electrolytic module comprises electrolysis cylinder; Described electrolysis cylinder comprises multiple electrolyte chamber be communicated with successively, and electrolyte chamber one end is provided with cathode guide electroplax, the other end is provided with anode conducting plate; Also comprise the ventilating mechanism to passing into air bottom electrolyte chamber; The inner side of described anode conducting plate and cathode guide electroplax is provided with recessed cambered surface; The flow deflector of at least one level is provided with in described electrolyte chamber.
Electroplating wastewater removes after insoluble impurity through filtration module, enters electrolysis cylinder, flows through multiple electrolyte chamber successively.Due in the utility model, multiple electrolyte chamber is provided with in electrolysis cylinder, the cathode guide electroplax of independently external source, anode conducting plate is equipped with in each electrolyte chamber, therefore by regulating the strength of current be applied on cathode guide electroplax, anode conducting plate, the electrolysis strength in each electrolyte chamber can be regulated respectively.Its electrolysis strength of electrolysis cylinder being arranged at electrolysis cylinder front end can be lower, separates out the most of metal in waste water with the state of less energy-consumption; And the electrolyte chamber at electrolysis cylinder rear portion progressively can promote electrolysis strength, to promote that the metal ion that in waste water, concentration is comparatively thin is separated out.By the mode of above-mentioned multistage electrolysis, the metal recovery rate of electroplating wastewater effectively can be improved.In addition, the utility model also passes into air when electrolysis to electrolyte chamber, to promote that metal ion spreads, to separate out.Ventilating mechanism can select any one existing techniques in realizing, as air pump.Especially, the inner side of anode conducting plate and cathode guide electroplax is provided with recessed cambered surface, can improve energising area, changes electric field density, to avoid because conducting plates fringe field density is too low and cannot normally electrolysis.Flow deflector then can promote that waste water intermediate ion moves to cathode guide electroplax, especially assembles to the centre that strength of electric field is higher, improves the precipitation rate of metal.Filtration module of the present utility model can select existing techniques in realizing.
Further, the outer ring of described electrolysis cylinder is wound with overflow groove, and the bottom of overflow groove is provided with leakage fluid dram, and leakage fluid dram is connected with waste liquid storage cylinder.
Be spilled over to overflow groove during the waste water overfill of electrolysis cylinder, focus on waste liquid storage cylinder through leakage fluid dram and store.
Further, described filtration module comprises at least one cartridge filter be arranged on above electrolysis cylinder electrolyte chamber foremost; Described cartridge filter comprises inner barrel and is sleeved on outer cylinder body outside inner barrel, also comprises the fluid inlet, inlet mouth, the multiple filtrate through holes be arranged on inner barrel wall, the filter bag that is arranged on the liquid outlet on outer cylinder body and is arranged in inner barrel that are arranged on inner barrel one end; Filter bag is provided with opening, and opening is arranged on described fluid inlet place; Described inlet mouth place is connected with an air pump.
Especially, waste water enters cartridge filter, and air pump pumps into air pressure to inner barrel, under gas pressure waste water through filter bag filtration, enter outer cylinder body by filtrate through hole, be finally expelled in electrolysis cylinder first electrolyte chamber foremost through liquid outlet.
