Abstract

The utility model relates to a multifunctional by-pass filter unit. The solid particle impurity is filtered by a main filtering cylinder (2), and 10%-15% of the total flow of the clean plating liquid is discharged from a main liquid discharging tube (5) to a by-pass filter cylinder (7) which is filled with processing agents (8) that is combined by II typed activated charcoal and metal ion adsorbent. The harmful metal ion impurity and organic impurity in the plating liquid are further filtered. The obtained purification plating liquid and the clean plating liquid with an 85%-90% flow quality are discharged together to a plating trough. In the continuous and circular filtering of the plating liquid, the large scale of process of the periodic stopping production that is caused by eliminating the impurity in the plating liquid in the plating industry before can be avoided or prolonged.

Description

Multi functional by-pass filter unit

A kind of multiple-effect bypass type filter, relate to electroplating industry produce in the treating plant of electroplate liquid.

At present, in electroplating industry, the filter of domestic production and use, adopt the cartridge filter of simple function mostly, the effectiveness that only has solid particle impurity in the elimination electroplate liquid, and harmful metal ion impurity and organic impurities still exist in the electroplate liquid, and the electroplating technology process is played ill effect, and therefore ubiquity electroplate liquid impurity is done the big processing that periodically stops production in electroplating industry is produced.Usually handle 4000 liters of bright nickel plating bath spends three round the clock greatly, and will lose the plating bath about 10%, these waste liquids bring very big harm to environment protection.

The utility model purpose: adopt shunting mode and physics, chemical effect,, further eliminate the harmful metal ion impurity and the organic impurities that produce in electroplating to the cleaning plating bath of elimination solid particle impurity.

Design of the present utility model: through the filterable cleaning plating bath of main cartridge filter, feed a bypass filter cylinder once more from the liquid discharge pipe of main cartridge filter, wherein utilize throttling valve to make it keep the 10-15% of total flux, physics and chemical effect take place by the treatment agent of being furnished with gac and metal ion adsorbent combination of superposition on bypass filter cylinder inner filter core in the cleaning plating bath; Copper in the adsorption liquid (Cu), iron (Fe), plumbous (Pb), zinc (Zn) ion and organic brightening agent decompose impurity as required, and then return coating bath with the cleaning plating bath of all the other 85-90% flows from main liquid discharge pipe.

The utility model is rational in infrastructure, and is easy to use, possesses multiple effectiveness.Can select 2000 liters/hour to 40000 liters/hour different flow as required for use, to satisfy all kinds of Electroplating Production scales.By continuous circulating filtration plating bath, constantly remove all kinds of impurity, general filter core and the transposing treatment agent of only need on schedule cleaning can greatly prolong the big processing cycle of plating bath even can avoid big processing, so just can save the electroplate liquid loss that causes by big processing, enhance productivity and economic benefit.

The utility model embodiment: by hermetically sealed magnetic drive pump (1) electroplate liquid is picked up from coating bath, the main tubing (14) along main cartridge filter (2) bottom injects in the main cartridge filter (2); Filter through the polypropylene honeycomb tubular filter element (3) that to go up 19 length erectting be 500MM of insulated chamber (4) panel (16) at the bottom of being positioned at tin, solid particle impurity becomes cleaning plating bath inflow insulated chamber (4) in the elimination liquid, insulated chamber (4) communicates with the main liquid discharge pipe (5) of main cartridge filter (2) bottom again, the cleaning plating bath is discharged by main liquid discharge pipe (5), through being attached at the adjusting of the throttling valve (6) on the main liquid discharge pipe (5), make the 10-15% cleaning plating bath of 10000 liters of total fluxs wherein flow into bypass filter cylinder (7) by the bypass tubing (15) that is positioned at bypass filter cylinder (7) bottom; All the other 85-90% cleaning plating baths flow out from the other end master liquid discharge pipe (13) that links to each other with throttling valve (6).The cleaning plating bath that has entered bypass filter cylinder (7) overflows into isolating cylinder (9) from bottom to up, be introduced into the vessel (17) of superposition on filter core (10) top, it is to be made of a kind of corrosion resistant pore screen cloth, the treatment agent (8) of 2.5Kg is housed in it, this treatment agent (8) is made up of N type gac and metal ion adsorbent, metal ion adsorbent can optionally be selected absorbing copper (Cu), iron (Fe), plumbous (Pb), zinc (Zn) ionic complexing agent for use, as two (2 ethylhexyl) phosphoric acid ester, gac and sorbent material can be made into certain proportion on demand.In order to prevent that treatment agent (8) from stopping up filtration channel, complexing agent is adsorbed in N type gac as two (2 ethylhexyl) phosphoric acid ester to form, the purification plating bath of processed dose (8) infiltration is polypropylene honeycomb tubular filter element (10) the inflow insulated chamber (11) by 7 long 250MM erectting on insulated chamber (11) panel once more, bypass liquid discharge pipe (12) through being positioned at tube bottom flows out and the effusive cleaning plating bath of main liquid discharge pipe (13) converges and returns coating bath.
