(54) BATH FOR CASCADE WASHING

one .

The invention relates to a washing technique, in particular, to devices for the electroplating and chemical treatment of parts, and can be used in any branch of Mechanical Engineering.

Famous bath for liquid processing products containing drain karmak with a flexible pipe, movably fixed inside the bath. When the latter is filled, the overflow edge of the vertical wall of the kirman is exposed on the working liquid mirror and then the pocket is fixedly attached to the walls of the bath: 1.

Such a device does not exclude instantaneous liquid discharge when the parts are immersed and the volume is drastically reduced, which degrades the flushing quality, and intensive flow is required to restore the volume of washing liquid.

A cascade rinse bath is also known, comprising an overflow septum, a drain pocket mounted on one of the bath walls, and a piping system 2.

The disadvantage of such a bath is that when diving products, especially volumetric ones, the volume of liquid in the bath is drastically reduced due to the salvo discharge through the drain pocket.

2

The aim of the invention is to improve the quality of washing by maintaining a constant volume of washing liquid in the bath with a constant balance of supply and discharge.

The goal is achieved by the fact that a bath for cascade washing, containing an overflow partition, a drain pocket mounted on one of the walls of the bath, 10 and the piping system according to the invention is equipped with an additional drain pocket mounted on the opposite wall of the bath and floats on the levers placed in each part of VENNA, while the wall of each drain pocket is moveable and the upper edge is pivotally connected to at least one float by means of a lever.

FIG. 1 shows a general view of the bath; in fig. 2 - the same, top view.

Bath 1 for cascade washing contains overflow partition 2, drain karm; en 3 mounted on one 25 of the walls 4 of bath 1, 5 piping system, additional drain pocket 6 mounted on the opposite wall 7 of this bath, floats 8, 9, 10 and 11 with arms Ш, 13, 14, and 15, located in parts 16 and 17 of the bath;

the walls 18 and 19 of the pockets 3 and 6 have the possibility of vertical movement and the upper edge is pivotally connected to the floats 8, 9, 10 and 11.

The piping system has a pipeline 20 for supplying washing liquid to both parts 16 and 17 of the bath 1 with filling valves 21, 22 and a drain pipe 23 with drain valves 24 and 25.

 works as follows. The washing fluid through conduit 20 and valves 21 and 22 fills both parts

16 and 17 of the bath 1. At that, the valve 24 of the part 16 of the bath 1 is closed, la the valve of the 25 part

17bn1 is open. Part 17 of the bath is filled to the level of the upper edges of the movable 19 and fixed (in the figures

not shown) of the vertical walls of the pocket 6, after which the valve 22 is closed. Part 16 of bath 1 is filled above the upper edge of the partition 2. The washing liquid enters part 17 of this bath. A directional movement of the fluid flow is established (in Fig. 1, this is indicated by solid arrows). Excess of it is discharged through pocket 6 with valve 21 constantly open.

When the shtangi with products is immersed in part 17 of bath 1, the liquid level rises, the floats 10 both float and raise the wall 19. The height of the liquid column above the upper edge of this wall remains constant, thereby eliminating the intensive discharge of liquid. The volume of washing liquid is maintained, which improves the quality of the wash.

When removing the bar with products from part 17 of bath 1, the floats 10 and 11 with the wall 19 of the pocket 6 are returned to their original position, and the liquid level is restored.

Edeli are transferred to part 16 of bath 1. The washing liquid is intensively poured into part 17, where the level rises again, floats 8 and 9 with wall 18

pocket 3 float, the salvo reset protection process is repeated.

When the flow direction changes, valves 22 and 25 are closed, valves 21 and 24 are opened. The direction of fluid flow in a casuade varies (in Fig. 1 it is shown by dotted arrows).

The transfer of the bar with the products also occurs in the reverse order: first to part 16, and then to part 17 of the bath. The operation and functions of the floats 8 and 9 and the walls 18 of the pocket 3 are similar to the work and functions of the floats 10 and 11 of the walls 19 karma.

The application of the proposed bath provides high quality washing products.
