Description

The invention relates to the field of electroplating and can be used on galvanochemical processing lines for parts and / or printed circuit boards made in standard and two-level layouts, under conditions of restrictions on production areas, for controlling the process of draining the processing medium from both process baths and from jet baths dynamic washing, depending, respectively, on the concentration of the main component of the used electrolyte / solution of the process bath, or on the concentration of the main washable com Ponent in the water used for flushing.

A device is known for changing in two directions a jet-dynamic washing of a stream discharged from a bath by a contaminated main washable water component, including a body equipped with a commuting draining flow mechanism with an electromagnetic drive, the inlet of which is connected by a pipe equipped with a concentration sensor of the main washable component to the drain hole of the jet bath dynamic washing, and the output is connected to the first output pipe, while the second output pipe is connected to the place once escheniya concentration sensor with a conduit connected with an input device for changing the discharged body fluids flow into two directions [1].

The disadvantages of the known device are:

- relatively large weight and size characteristics of the housing with a commuting flow-draining mechanism, made in the form of an electromagnetic valve, the dimensions of which, with a diameter of the inlet pipe from 50 to 100 mm, can reach up to 0.5 m and weight up to 25 kgf;

- the mandatory presence of the residual amount of the electrolyte to be drained diluted with water (in this case) at the inlet of the mechanism switching the drained stream.

The closest to the proposed technical essence and the achieved result, the known solution, selected as a prototype, is a device for changing in two directions the jet-dynamic washing washed out of the bath, which is part of a galvanic line made in a two-level layout, the flow of the process bath diluted with water, including a body equipped with a switching flow-merging mechanism with an electromagnetic drive, made in the form of a three-way electromagnetic valve, the inlet of which is connected by a pipeline to the drain hole of the jet-dynamic washing bath, and its two outlets are connected, respectively, with a collector of a part more concentrated in the main washable component and with a collector of a less concentrated part of the main washable component [2].

The disadvantages of the known device selected as a prototype are:

- even larger in comparison with [1] the weight and size characteristics of the housing with a commuting flow-draining mechanism made in the form of a three-way (in this case) electromagnetic valve;

- limited functional and technological capabilities that do not allow or make it difficult to use, in particular, three-way solenoid valves for changing the flow of the processing medium drained from the bathtubs, taking into account the designs of both standard and made in two-level layout of galvanic lines.

The technical result consists in reducing the weight and size characteristics of the device for changing in two directions the flow of the processing medium drained from the bath and simplifying its implementation.

A new technical result is achieved by the fact that in the known device for changing in two directions the flow of the processing medium drained from the bath, including a body equipped with a switching mechanism to merge the flow of the bath, the input of which is connected to the drain of the bath, and its two outputs are connected by pipelines to the process baths of the process bath of various concentration according to the invention, the body of the device for changing in two directions the flow of the processing medium drained from the bath is performed in the form of a connected its upper surface with a drain of a bathtub, a closed volume of a ∇-shaped profile, the side surfaces of which are connected to the outlet pipelines, and the switching commutating flow mechanism is performed in the form placed in the holes and / or clips-supports in the lower part of the end surfaces of the closed volume of a ∇-shaped profile, axis, with a double-sided tray, which is inextricably connected to it, with the possibility of angular movement, depending on the concentration of the process bath being drained by the processing medium.

The angular movement is performed either manually using a lever or lever system rigidly connected to the axis of the lever, or automatically using the output element of the rotary actuator connected directly to the axis or through the lever system.

The outlet pipelines of the device body for changing the flow discharged from the bathtub are made with a square cross section.

In this case, the lateral surfaces of the closed volume of the профиля-shaped profile are made with fixing screws placed around their perimeter, used for connecting with nuts to the outlet pipelines equipped with mounting holes around their perimeter.

At least one of the two end surfaces of the device body is equipped with fixing screws for connecting to the corresponding holes, it is also equipped with a hole for accommodating the axis of the lid connected to the support clip located in the lower part of at least one of the two end surfaces, a through groove, the upper part of which is articulated or articulated during manufacturing with a transverse groove made in the upper surface of the housing and placed at its center for placement through the through groove in the end face xnosti and placement in the transverse groove of the upper part of the double-sided tray at the stage of its initial installation in the housing, with a groove height equal to or greater than the vertical movement of the tray after the final installation of its axis in the hole and / or clip-support, located in the lower part of the end surfaces of the closed volume of the ∇-shaped profile, with subsequent fixation of the position of the tray inside the case with the help of an installed cover.

In addition, the lid is equipped with a protrusion placed during articulation in the through groove of the end surface of the housing and made of a thickness equal to the thickness of the latter.

In this case, the double-sided tray is placed in a lodgement installed in the lower part of the closed volume of the ∇-shaped profile, equipped with guides for draining the drained liquid, placed on the lower inner surface of the outlet pipelines.

The end upper and lateral surfaces of the tray are equipped with either an edging of elastic material, which is used as fluoroplastic, silicone, acid-base rubber, or are made together with the axis as a mortgage element in the form of a monostructure obtained by casting, made depending on the temperature and / or toxicity of the merged a stream of polypropylene, polyvinyl chloride, polyethylene or fluoroplastic.

And each of the sides of the tray is equipped with additional guides for drainage of the drained liquid, placed in its lower part, above the axis of the tray and inseparably connected both with the main guide plate and with the end surfaces of the tray.

As a rotary actuator, a single-turn electric actuator is used, including with a gearbox and / or with the angle of rotation of its output element that is adjustable or manually or automatically set.

The magnitude of the change in the angle of movement of the tray is selected, depending on the diameter of the inlet pipe in the range from 30 to 90 °.

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

- much smaller weight and size characteristics of the housing in the form of a closed volume of a ∇-shaped profile with a switching mechanism merging flow, performed in the form of bearings, bearings installed in the lower part of the end surfaces of the closed volume of a closed volume of a ∇-shaped profile, the axis with a plate rigidly connected to it a tray with the possibility of angular movement, depending on the concentration of the process bath being drained by the processing medium;

- expanded functional and technological capabilities that allow the use of devices manufactured according to the proposed method for changing in two directions the flow of the processing medium discharged from the bathtubs in both standard and two-level configurations of galvanic lines;

- a simpler design of the device for changing the flow of the processing medium drained from the bath in two directions, etc.

Comparison of the claimed solution not only with the prototype, but also with other technical solutions in other areas of technology showed that a device is known for changing in two directions from the working fluid discharged from the washing machine with the jet-forming manifolds, equipped with an integrated working fluid distributor connected to a hydraulic cylinder equipped with a rotation sensor controlling the rotation of the distributor of the flow of the working fluid in two compartments with the corresponding type of working fluid [3].

The disadvantages of this device are:

- even larger in comparison with [2], the mass and size characteristics of the housing with a mechanism for switching the discharge flow, made in the form of a mounted distributor of working fluid, connected to a hydraulic cylinder equipped with a rotation sensor, controlling the rotation of the working fluid flow distributor in two compartments with the corresponding type of working fluid;

- the relative complexity of manufacturing a device for changing in two directions by this method;

- limited functional and technological capabilities that prevent or make it difficult to use it to change the flow of the processing medium from the bathtubs of galvanic lines, taking into account the design features, both standard and made in a two-level layout, the latter.

In this case, the angular movement of the axis 8 with the tray 9 in the housing 1, variable, depending on the diameter of the drain pipe 21, in the range from 30 ° to 90 °, is carried out using a rotary actuator (PIM) 33, the output element of which is directly or through a system of levers (not shown) is connected to the axis 8.

And the cover 28 is equipped with a protrusion (not shown) placed (when articulated) in the through groove 5 of the end surface 3 of the housing 1 and made with a thickness equal to the thickness of the latter.

The outlet of the submersible pump and / or valve for draining the electrolyte / solution from Ex. In connected by a pipeline to the input of the device for changing in two directions merged from Pr. In the flow of the electrolyte / solution, the outlets of which are connected by pipelines to the inlets, respectively, of the tank for draining the electrolyte In (TSB Pr.

And the output of the LNS 31 through the control valve is connected through a check valve (not indicated), with those located in Pr. In collectors with EFSP (not indicated) for supplying more contaminated with the main washable component (OLC) In the wash water from the collection tank 29.

At the same time, they are located in Pr. The collectors with EFSP are also connected through a second check valve and a control valve to the second output of a three-way solenoid valve (not indicated), the first output of which (index 2) is connected to the collectors 23, 24 with elements 25 of the formation of jet streams for supplying washing water through the check valve 27 (in this case), also connected through a non-return valve 26 and a control valve (not indicated) with the output of the LNS 32 for supplying a less contaminated main washable component (OOK) In the wash water from the collector 30.

The implementation of the proposed device is presented on the example of the functioning of the jet dynamic washing bath in the bathtub, made in a two-level layout, of the galvanochemical processing operating module shown in FIG. 3.

In the initial state, in the collector 29 and collector 30 there are, respectively, more polluted and less polluted by the main washable component (KLO) of the process bath (Pr. B), the wash water, and LNS 31 and 32 are in the off state.

The tray 9 in the housing 1 of the device for changing in two directions drained from the bath 22 is in the position shown in FIG. 2, thereby providing switching of the process bath (Ex. B), which is more polluted from the bath 22 and is more contaminated with the main washable component (KLO) of the process bath (Ex. B), into the collection tank 29 of the latter.

After finishing the parts in Pr. In they are discharged from the latter, during or before the start of which the LNS 31 is turned on, thereby ensuring the supply of the wash bath from the collector 29, which is more contaminated with the main washable component (CLE) of the process bath (Pr. B), through the check valve, to those located in Pr. In collectors with EFSP.

At the same time, the surface discharged from Pr. The parts receive jets contaminated with the main washable component (KLO) of the process bath (Ex. B) of the wash water, thereby reducing the concentration of electrolyte / solution carried out by the details by an order of magnitude. AT.

Then, the unloaded parts are moved and loaded into the jet-dynamic washing bath 22.

Further, the parts are first unloaded from the bath 22. In the process or before the start of which the LNS 32 is turned on, thereby ensuring the supply of the wash bath from the collector 30 of the latter, less contaminated with the main washable component (KLO) (Pr. B), through the return valve 26, in the manifolds 23, 24 located in the bathtub 22 with EFSP 25.

At the same time, jets of less contaminated main washed component (OOK) In washing water, thereby providing a decrease by an order of magnitude of the concentration of electrolyte / solution introduced into the bathtub 22 by the parts. AT.

The stock of contaminated washing water formed during jet dynamic washing flows through the tubing 21 of the bathtub 22 into the housing 1 and along the left half installed in the right, in this case, position of the double-sided tray 9, along the guides 12, 17 into the pipeline 19 and then to compilation 29.

After the discharge of the volume of washing water formed during jet dynamic washing, the moment of onset control of which can be determined by:

- the signal of the flow switch installed on the pipe 21;

- drain time (based on statistics or timer signal);

- the signal of the sensor about the completion of the level change set in the corresponding collection, etc.,

turn on the rotary actuator (PIM) 33, forcing to rotate counterclockwise (in this case) its output element and the axis 8 connected to it, and therefore permanently connected to the axis 8 of the double-sided tray 9, translating the latter into the left one, indicated by a dotted line on FIG. 2, position.

In this case, the control of the extreme positions of the tray 9 and the control of the process of its movement can be carried out by installing a reed switch and a permanent magnet in the upper part of the housing 1, placed, for example, also in the upper part of the end upper 14 and / or side surfaces 15, 16 of the tray 9.

At the same time, the parts are re-loaded into the bath 22, after which the discharge of the volume of washing water formed during the first jet-dynamic washing is complete drained, the LPS is turned on, the input of which is connected to the clean wash water collector (SCPV), and its output is connected through control valves (not labeled), respectively, with a tank for draining contaminated rinsing water (BSZPV) and an inlet (index 1) of a three-way solenoid valve, the first output of which (index 2) is connected (in this case) through the return valve 27, with collectors 23, 24 with EFSP 25 located in the bathtub 22, thereby ensuring the supply of clean wash water from its collection (SCPV).

At the same time, jets of clean washing water come to the surface of the parts that are secondarily unloaded from the bath 22, thereby reducing by an order of magnitude the concentration of electrolyte / solution taken out by the parts from the bath 22. In after the first operation of jet-dynamic washing in the bath 22.

The runoff formed during the second jet-dynamic washing is less contaminated with KLO In the wash water it enters through the pipe 21 of the bath 22 into the housing 1 and along the right half installed in the left, in this case, position of the double-sided tray 9 (shown by the dotted line in Fig. 2), along the guides 13, 17 - into the pipe 20 and then compilation 30.

After that, the parts discharged from the bath 22 are moved and loaded into the flushing water (not indicated), equipped with a bubbler and a valve, for draining the contaminated wash water over the maximum permissible concentration (BSZPV), by immersion washing bath (RW), where they are subjected to final washing in this operating module.

In this case, if the runway reaches pollution in water (in the form of KLO Pr. B) in excess of the MPC value, the following is sequentially produced:

- opening the valve to drain contaminated washing water in excess of the maximum permissible concentration (not indicated in Fig. 3) into the tank for draining contaminated washing water (BSZPV);

- closing the shut-off valve (3 not indicated) of the collection of clean washing water (SCPV);

- opening the shut-off valve (not indicated) BSZPV, thereby ensuring the supply of flushing water contaminated in excess of the MPC value from the LNS for its use, at least during the second jet-dynamic washing of parts in the bath 22.

In addition, if necessary, drain the electrolyte / solution from Ex. In, for example, for unloading those that fell during processing to the bottom of Pr. In the details, repair of the latter or with a significant (several days) period of not using galvanic equipment (weekends, holidays, etc.), the proposed device for changing in two directions the flow of the processing medium drained from the bath can be used (see Fig. 3 ) to direct the electrolyte / solution B and diluted (after supplying, for example, pure water from the MPSB, through the second outlet, index 3, of a three-way solenoid valve and non-return valve, to collectors with EFSP Pr. B) its parts, respectively, to the electrolyte drain tank Pr. In (TSB Pr. B) and the collector-concentrator of electrolyte Pr. B (SKE Pr. B).

And to speed up the process of draining the processing medium, in particular, from the baths of jet dynamic washing, the latter can be equipped with two proposed devices for changing in two directions the flow of the processing medium being drained from the bath, performed both with two rotary mechanisms and with one, using , in the latter case, a common axis connected to the respective trays.

Thus, the proposed method in comparison with the known, selected as a prototype, allows you to provide:

- much smaller mass and size characteristics of the device body for changing in two directions the flow of the processing medium discharged from the bath, realized as a closed volume of a ∇-shaped profile, with a mechanism commuting the flow being drained, made in the form of a closed volume ∇- located in the end surfaces of the end surfaces shaped profile bearings, bearings, axis with a rigidly connected plate-tray, with the possibility of angular movement, depending on the concentration of the merged processing fluidized bed of process baths;

- expanded functional and technological capabilities that allow the use of devices for changing in two directions the flows of the processing medium being drained from the bathtubs in the constructions of both standard and made in a two-level layout of galvanic lines;

- a simpler design of the device for changing the flow of the processing medium drained from the bath in two directions, etc.

The implementation of the proposed device does not meet fundamental difficulties.

So the device’s body for changing in two directions the flow of the processing medium drained from the bath and the double-sided tray can be made both collapsible and in the form of monostructures obtained using a 3D printer or by casting thermoplastic material into appropriate molds, which can polypropylene, polyvinyl chloride, polyethylene or fluoroplastic should be used, using titanium or stainless steel as embedded materials.

As a rotary actuator, standard or a single-turn electric actuator with adjustable or manually set or automatically the angle of rotation of its output element, or a stepper motor of the AD, FL series for a supply voltage of 12 (24) V can be used.

As output pipelines, both standard and specially manufactured products can be used, obtained by casting into the appropriate molds of a thermoplastic material, for example polypropylene or polyethylene.

Checking the proposed device when used as a rotary actuator equipped with a lever connected to the lever of the axis of the rotary plate-tray of a standard electric motor for cleaning the windshield of a passenger car VAZ-2115 for a supply voltage of 12 V, gave a positive result.
