Description
Technical field
The utility model relates to the treatment unit before a kind of the spraying.
Background technology
The acid-etched degreasing technique that aluminum alloy surface is processed is that degreasing, alkaline etching, the scrubbing bright dipping three process with traditional technique is combined into a procedure, reduce costs and save the energy, aluminum alloy surface after treatment is smoothly bright and clean, kept the original gloss of aluminium alloy, aluminium dissolving waste and tank liquor precipitation are few, good with the chromate conversion treatments matching performance, be adapted to especially the front surface treatment of aluminium alloy extrusions spraying.In long-term production application, treatment process before the aluminum alloy surface spraying is comparatively simple, and the treatment unit of acid-etched degreasing, raising smooth finish before spraying for aluminium, normally build several large ponds with cement in the workshop, although this method cost is lower, use also more for convenience, but have a lot of problems.For example: 1, the pond volume is larger, takies the factory building space; 2, Chi Kou opens wide, and easily has the workshop dust and other impurities to fall into the pond, affects treatment effect; 3, the pond body is higher, and the workman operates inconvenience, has potential safety hazard; 4, each clean water yield of injecting is larger, in case after becoming trade effluent, discharge to environment in a large number, has both wasted the water source, again can not recycle.
Summary of the invention
treatment unit before a kind of the spraying discloses a kind of new technique for addressing the above problem exactly, comprise: alkali cleaning pond (1), washing pool (2), pickling tub (3), clean water basin first (4), clean water basin second (5), chromaking pond (6), clean water basin third (7), clean water basin fourth (8), drench pool (9), stoving oven (10), wherein alkali cleaning pond (1), washing pool (2), pickling tub (3), clean water basin first (4), clean water basin second (5), chromaking pond (6), clean water basin third (7), clean water basin fourth (8) close-packed arrays are together, it is characterized in that: described alkali cleaning pond (1), washing pool (2), pickling tub (3), clean water basin first (4), clean water basin second (5), chromaking pond (6), clean water basin third (7), clean water basin fourth (8) the case shape that all is rectangle, closely side-by-side in order, drench pool (9) is near clean water basin fourth (8), and stoving oven (10) is near drench pool (9), and each pond is near the both ends at 20cm suitable for reading place, and correspondence arranges two overflow weir (1a respectively, 2a, 3a, 4a, 5a, 6a, 7a, 8a), each pond one end arranges respectively a blow-off pipe (1b near the bottom, pond, 2b, 3b, 4b, 5b, 6b, 7b, 8b) and wash water valve (1c, 2c, 3c, 4c, 5c, 6c, 7c, 8c), each blow-off pipe all is connected with header (11), in alkali cleaning pond (1), (6) three ponds of pickling tub (3) and chromaking pond suitable for reading arranges respectively an air pump, and air pump pipeline front end probes into alkali cleaning pond (1), pickling tub (3) and bottom, (6) three ponds, chromaking pond, header (11) is connected to water treating pond.
This apparatus structure is simple, easy for installation, production cost is low, due to the mode that adopts close-packed arrays to place, can be according to factory building environment installation on the spot, saving factory building space, the box setting in each pond reduces the pond open area greatly, is convenient to hide, and avoiding dust and other impurities to fall into affects spraying effect in the pond, simultaneously the water yield in each pond is convenient to accurate control, in order to configure each pond strength of fluid; Adopt header, wash water valve to realize concentrating or disperseing discharging, and institute's waste discharge is carried out recycling after purifying treatment, save the water source, environmental contamination reduction.
Description of drawings
Referring to accompanying drawing, Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, specific features of the present utility model is described further.
Referring to Fig. 1, comprising: alkali cleaning pond (1), washing pool (2), pickling tub (3), two clean water basin first (4), clean water basin second (5), chromaking pond (6), clean water basin third (7), clean water basin fourth (8), drench pool (9), stoving oven (10), overflow weir (1a, 2a, 3a, 4a, 5a, 6a, 7a, 8a), blow-off pipe (1b, 2b, 3b, 4b, 5b, 6b, 7b, 8b), wash water valve (1c, 2c, 3c, 4c, 5c, 6c, 7c, 8c) and header (11); During use, inject clear water to each pond respectively by header (11), close wash water valve after reaching predetermined amount of water, and join by demand according to the water yield in each pond and put soda acid dosage, and booster air pump pneumatic stirring alkali cleaning pond (1), pickling tub (3) and chromaking pond (6), aluminium section bar is sprayed in pretreatment process, and air pump is always in running order, makes that in the pond, potential of hydrogen is in uniform state.Aluminium section bar after processing is suspended on drench pool (9), carries out drying and processing without aluminium section bar being inserted stoving oven (10) after dripping again.After liquid contamination in the pond, can replace separately for the water body in the pond of having polluted, open the valve draining-off sewage, process through header (11) injected water treating pond, in the pond, sewage discharge can be cleaned impurity at the bottom of pool wall and pond after clean in advance, clean with flushing with clean water after, inject clear water at Xiang Chizhong, join and put acid or alkali and the rear continuation production and application that stirs, after the dirty water decontamination handles in treating pond, then be used for replacing waste water in other pond.
