Description

The invention relates to designs of bathtubs for galvanic or chemical treatment, as well as washing parts, in particular bathtubs made of metal, including its subsequent lining, and can be used in the manufacture of bathtubs for both stationary sections and traditional made in a single-level layout, automated (mechanized) galvanochemical processing lines, or lines made in a two-level layout (with baths at the upper level and tanks - electrolyte / solution collectors on and lower), both with unilateral and bilateral onboard suction.

The closest solution to the proposed technical essence and the achieved result, chosen as a prototype, is a galvanic bath with a drain pocket containing a rectangular tank made of metal or metal with its subsequent lining, consisting of a bottom, side and end walls with horizontal the sides along the perimeter of the tank, the protrusions in the side walls of which are inseparably connected with the drain pocket located between them, in their upper part, equipped with a drain cartridge com [1].

A disadvantage of the known device, selected as a prototype, is the relative complexity of manufacturing a bath tank, due to the need to perform one-piece connection, as a rule, by welding the corresponding end and bottom parts of the drain pocket equipped with a drain pipe with corresponding protrusions in the side walls of the bath tank.

Another disadvantage of the known method, selected as a prototype, is also the relative complexity, given the relatively small dimensions in width (of the order of 100-150 mm) and significant (at least 10-20% of the height of the tank) dimensions in height of the drain pocket, the lining itself pocket [2], and (even more so) the inner surface of its drain pipe.

In addition, the known device has comparatively limited capabilities in terms of unification of design and technological solutions for the drain pockets themselves, associated with the need to process even larger parts than previously processed parts, which may lead to poor quality , for example, two-stage countercurrent flushing [3].

Finally, another disadvantage of the known device is the relatively limited functional and technological capabilities of the design of its drain pocket, which does not allow, in particular, the installation of collectors with holes, in particular for the destruction of the foam coming from the tank chemical degreasing or phosphating with the ability to adjust their position in drain pocket, replacement and easy maintenance.

A new technical result is to simplify the implementation of the design of the bathtub with a drain pocket, expand its functional and technological capabilities and increase the unification of the used design and technological solutions.

A new technical result is achieved in that in a galvanic bath with a drain pocket containing a rectangular tank, consisting of a bottom, side and end walls with horizontal sides along the perimeter of the tank, one of the walls of which in the upper part is detachably connected to a drain pocket equipped with a drain pipe , according to the invention, the wall of the tank reservoir with a drain pocket has a drain visor in the upper part, equipped with end faces on the end sides, inseparably connected to the horizontal the mouth and the wall of the tank, while the said wall of the drain pocket is made with a groove longer than the length of the drain visor with protective flanges, and the groove and the end surface of the groove, depending on the shape of the lower part of the protective flanges, are made, respectively, with or without bevel and / or with through grooves for articulation with the end surface of the protective peaks, while the end surface of the remaining walls of the drain pocket coincides with the lower surface of the corresponding sections of the horizontal side of the tank reservoir, and The willow pocket is made of a material resistant to temperature and / or the aggressive environment of the bath processing medium.

Moreover, the drain pocket is made with smooth or threaded holes in the upper part of its end sides for one-piece or detachable placement in them, respectively, of fittings for the output of cables or wires from electric heaters performed with heating of the bath and collector for jet destruction of the foam coming from the bath.

In this case, the drain pocket is equipped with a lid detachably articulated with its upper frame, and an on-board suction is installed on the lid.

A drain pocket is made by gluing or welding sheet material, which, depending on the temperature and / or aggressiveness of the bath processing medium, is made of polypropylene, polyvinyl chloride, polyethylene or fluoroplastic, and a detachable connection of the drain pocket to the bath reservoir is realized using a screw-nut pair with the use of lugs in the wall of the pocket adjacent to the corresponding wall of the tank of the bath, and holes in the corners that are inseparably connected with the body of the bathtub.

And the drain pipe of the drain pocket is made in the form of a pipe segment from the material used in the manufacture of the drain pocket, one-piece connected to the bottom of the latter.

Moreover, the number of drain pipes in the drain pocket, when processing large parts in the bath, is set to at least 2.

A comparative analysis of the proposed solutions with the prototype shows that the claimed device allows to provide:
