Description

 The invention relates to the field of galvanochemical processing of parts on suspensions, in particular when using unheated (“cold”) electrolytes of process baths (galvanizing, cadmium plating, etching, etc.), and can be used both as part of automated (mechanized) lines of electroplating, and in the form of autonomous automated installations configured for a specific operation (processing + flushing).

 A well-known operating module for non-drain galvanochemical processing of parts on suspensions, containing a bath located in a technological sequence for galvanochemical processing with an overflow pipe, a three-stage washing bath with jet formation elements and a drain pipe, a diluted electrolyte collector connected by a pipeline and a pump installed at its inlet, and its inlet is an overflow pipe with a bathtub for galvanochemical treatment, a collection of contaminated water, closed by a pipeline established at the output of the pump and the filter and the inlet - with the drain pipe washing tub unit concentration and separation on a fraction of the electrolyte is closed piping and connected at its input with the collection pump dilute electrolyte [1].

 A disadvantage of the known device is the relatively large energy consumption due to the need for concentration and fractionation of a significant amount of diluted electrolyte, in particular, at the initial stage of operation of the module.

 Another disadvantage of this device is its relatively limited technological and functional capabilities, which do not allow, in particular, to ensure the washing of parts and cleaning water from treatment products that are free of associated products, containing the main washable component in technologically permissible concentrations.

 Closest to the claimed technical essence and the achieved result, the known solution, selected as a prototype, is an operating module of non-discharge galvanochemical processing of parts on suspensions, containing a bath for galvanochemical processing with an overflow pipe, the first jet washing bath with a drain pipe and with jet forming elements, a second jet washing bath with a drain pipe and with jet forming elements, as well as a washing bath and immersion with an overflow pipe and closed to it, through the pipeline and a pump installed at its inlet, a filter for deep cleaning of washing water, a collection of contaminated diluted electrolyte connected by a pipeline and a pump installed at its outlet and through the overflow pipe, with a bath for galvanochemical treatment, a collection of contaminated water connected at the inlet to the overflow pipe of the wash bath by immersion, and at the outlet, through the pipeline and pump, with the elements of the formation of jets of the first jet bath oh washing, a demineralized water collector connected by a pipeline and a pump installed at its outlet with elements of forming a jet of a second jet washing bath, a concentration and electrolyte separation unit into fractions, closed by a pipeline and a pump installed at its inlet with a contaminated diluted electrolyte collector, and the second outlet, the concentration and electrolyte separation unit into fractions is connected to the demineralized water collector, the first jet washing bath is connected through without a drain pipe with a collector of contaminated diluted electrolyte, and the second jet washing bath is connected through a drain pipe to a collector of contaminated water.

 The disadvantages of the known device selected as a prototype are its relatively high specific energy costs associated with the need for one-time concentration of a relatively significant amount of the diluted electrolyte of the galvanic chemical bath formed in the corresponding collection after the processing operation in the first jet washing bath due to limited functional technological capabilities of the device in terms of the use for these purposes of different processing media with different flow characteristics.

 Another disadvantage of this device is the relatively low quality of jet washing operations, due to the lack of technical equipment and equipment for cleaning the electrolyte and washing water from impurities and (or) associated processing products (STR), which can lead to secondary pollution of the surface of the processed parts, faster clogging of the corresponding elements of the formation of jets, as well as deterioration in the quality of galvanochemical treatment as a whole.

 A new technical result is to reduce the unit cost of energy resources, expand the functional and technological capabilities and improve the quality of blasting operations and the galvanochemical treatment process as a whole.

 A new technical result is achieved by the fact that the operational module of non-discharge galvanochemical processing of parts on suspensions, containing a bath located in the technological sequence for galvanochemical processing with an overflow pipe, a first jet washing bath with a drain pipe and jet forming elements, a second jet washing bath with a drain pipe and with the elements of the formation of jets and a wash bath by immersion with an overflow pipe and with a closed connection to the bathtub, through a pipeline and installed at its inlet there is a pump, a filter for deep cleaning of washing water, a collection of contaminated electrolyte with a pump and a pipe installed at its outlet, a collection of contaminated water with a pump and a pipe installed at its outlet, a desalinated water collector with a pipe connected to the elements of the formation of jets of the second jet washing bath and a pump installed at its outlet, a concentration and separation unit for electrolyte fractions, connected by its second outlet via a pipeline to a demineralized water collector, moreover, the first jet washing bath is connected through a drain pipe to a contaminated diluted electrolyte collector, and the second jet washing bath is connected through a drain pipe to a contaminated diluted electrolyte collector, and the second jet washing bath is connected through a drain pipe to a contaminated water collector, according to the invention, it is provided with a purified collector electrolyte connected to the inlets of two pumps, at least two devices for regulating the pressure of the jets of washing liquid, the collector is cleaned water, connected through a pipeline to the pump inlet, the outlet of which is connected by a pipe to the input of the actuator for supplying purified water, through the corresponding pipeline, to the jet formation elements of the first jet washing bath, by a generator (source) of compressed air, connected by a pipeline to the input of the actuator for compressed air supply, through the corresponding pipeline, to the jet formation elements of the first jet washing bath, by two devices for supplying liquid in two m directions, a filter for cleaning contaminated electrolyte from impurities and (or) associated processing products, connected at its input to the outlet of the pump of the collection of contaminated diluted electrolyte, and output at the inlet of the first device for supplying liquid in two directions, a filter for cleaning contaminated water from impurities and (or) associated processing products, connected at its inlet to the outlet of the pump for the collection of contaminated water, and the outlet to the inlet of the second device for supplying liquid in two directions, and t equipped with actuators for supplying demineralized water, the inlets of which are connected by appropriate pipelines to the outlet of the pump of the demineralized water collector, the outlet of the first actuator being connected by a pipeline to the purified water collector, the output of the second actuator is connected by a pipeline to the jet forming elements of the second jet washing bath, and the output of the third the actuator is connected by a pipeline to the elements of the formation of jets of the first bath jet washing, the output of the pump the collector of contaminated diluted electrolyte is connected by a pipeline to the input of a filter for cleaning contaminated electrolyte from impurities and (or) associated processing products, the output of which is connected by a pipeline to the input of the first device for supplying liquid in two directions, the outputs of which are connected by pipelines to a collector of contaminated diluted electrolyte and a collection of purified electrolyte , the output of the first pump of the latter is connected to the input of the concentration and separation of electrolyte fractions, the first od conduit which is connected with the collection of the purified electrolyte, a second pump whose output is connected through a duct with a bath for galvanochemical processing apparatus outputs the second liquid supply in two directions are connected by pipelines with a collection of dirty water collection and purified water, respectively.

 Moreover, the collection of contaminated diluted electrolyte and the collection of purified electrolyte are interconnected through an overflow weir with an adjustable overflow height and a filter element installed directly in the overflow weir or in an overflow pocket connected to it.

 The collection of purified water, the collection of contaminated water and the collection of demineralized water are interconnected via overflow partitions with adjustable overflow height and filter elements installed directly in the overflow partitions or in the overflow pockets connected to them.

 And, at least, the bath for galvanochemical processing is equipped with a device for draining the electrolyte from its bottom.

 In this case, the device for draining the electrolyte from the bottom of the bath for galvanochemical processing is made in the form of a screen not reaching the bottom of the inert material relative to the electrolyte, rigidly connected in its part to the upper edge of the overflow pipe of the bath for galvanochemical processing.

 Comparative analysis with the prototype shows that the inventive device is characterized by the presence of a purified electrolyte collector, two devices for regulating the pressure of the washing liquid jets, a purified water collector, a compressed air generator (source), two devices for supplying liquid in two directions, a filter for cleaning the contaminated electrolyte from impurities and (or) related processing products, a filter for cleaning contaminated water from impurities and (or) related processing products, an actuator for Aci compressed air, and a number of new pipelines, pumps and two additional series of new compounds. Thus, the claimed device meets the criteria of the invention of "novelty."

A comparison of the proposed solutions with other well-known in science and the field of technology shows that there are known technical solutions [3], providing a continuous mode of operation of the operating module of a closed-circuit galvanochemical processing. However, their use has a number of significant drawbacks that do not allow to achieve the goal set in the claimed solution, since their implementation requires:
- the presence of only externally controlled devices for supplying fluid in two directions, in particular, when the separation of the fluid flow occurring during its discharge from the jet washing bath;
- coordination of the filter performance for cleaning contaminated diluted electrolyte with the performance of the concentration unit and separation of electrolyte fractions;
- the relatively large cost of energy used during the operation of the unit for concentration and separation of electrolyte fractions associated with the relatively large amount of water consumed by jet washing, in particular, due to the inability to use for the purpose of the last air-water mixture and changing the pressure parameters of the washing water supplied into the elements of the formation of jets.

 This allows us to conclude that the claimed technical solution meets the criterion of "significant differences".

 The drawing shows a structural diagram of the operating module of the non-drain galvanochemical processing of parts on suspensions.

 The operation module of the non-discharge galvanochemical treatment of parts on suspensions comprises a bath 1 for galvanochemical treatment with an overflow pipe 2 located in the technological sequence, a first jet washing bath 3 with the jet forming elements 4 and a drain pipe 5, a second jet washing bath 6 with the jet forming elements 7 and a drain piping 8, immersion flush bath 9, equipped with an overflow pipe (not shown in FIG. 1), a drain pipe 10 with a pump 11 and a level indicator-regulator 12 I, connected by a pipeline (not shown in FIG. 1) to a demineralized water generator (not shown in FIG. 1), a filter 13 for deep purification of washing water, as well as a purified electrolyte collector 14, a contaminated diluted electrolyte collector 15, purified water collector 16, collector 17 of contaminated water, collector 18 of unpolluted demineralized (distilled) water, block 19 for concentration and separation of electrolyte fractions, filter 20 for cleaning contaminated electrolyte from impurities and (or) associated processing products (STR), filter 21 for cleaning Contaminated water from impurities, and (or) products of related processing. (SPO), devices 22,23 for supplying fluid in two directions, pumps 24, 25, 26, 27, 28, 29, a generator (source) 30 of compressed air connected by a pipe 31 to the input of the actuator (IM) 32 for supplying compressed air, through the pipe 33, into the elements 4 of the formation of jets of the bath 3, as well as the device 34.35 for regulating the pressure of the jets of the washing liquid.

 The outputs of the pumps 24 and 25 of the collection 14 are connected by pipelines 36 and 37 with the input of the block 19 and the bath 1, respectively.

 The first output of the block 19 is connected by a pipe 38 to the collector 14, and the second output of the block 19 is connected by a pipe 39 to the collector 18.

 The collector 15 is connected by means of a pump 26 and a corresponding pipeline to the input of the filter 20, the output of which is connected by a pipe 40 to the input of the device 22, the second output of which is connected by a pipe 42 to the collector 14, and the first output of the device 22 is connected by a pipe 41 to the collector 14, which is also connected overflow pipe 2 bath 1 and drain pipe 5 bath 3.

 The collection 16 is connected by means of a pump 27 and a pipe 43 to a pipe 33, the output of which is connected to the elements 4 of the bath 3, and the input of the device 35, the output of which is connected by a pipe 50 to the collection 16.

 The collector 17 is connected through a pump 28 and a corresponding pipeline to the input of the filter 21, the output of which is connected by a pipe 44 to the input of the device 23, the second output of which is connected by a pipe 45 to the collector 16, and the first output of the device 23 is connected by a pipe (not indicated in Fig. 1) with collector 17, which is also connected to the drain pipe 8 of the bath 6.

 The collector 18 is connected through a drain pipe 46 to a pump 29, the output of which is connected by a pipe 47 to the input of the device 34, the output of which is connected by a pipe 48 to the collector 18, and by a pipe 49 to the elements 7 of the bath 6.

 The filter 13 is connected by a pipe 51 to the outlet of the pump 11, and a pipe 52 with a bath 9.

 The filter 13 contains, for example, sorption or ion-exchange columns 53 with a sorbent or resin corresponding to the processing type.

 Bath 1, collectors 14, 15, 16 and 17 are equipped with level sensors 54, 55, 56, 57 and 58, respectively, with the corresponding number of monitored values of the latter.

 The collection 18 is equipped with a regulator-signaling device 59 of the level, connected by a corresponding pipeline to the output of the generator (source) of demineralized (distilled) water, also connected to the regulator-signaling device 12 of the bath 9.

 The collectors 14 and 18 respectively contain sensors 60 and 61 of the concentration of the main washable component of the electrolyte of the galvanochemical treatment of the bath 2.

 In this case, the collectors 14 and 15 are interconnected by an overflow partition (not indicated in Fig. 1) with a filter element (not shown in Fig. 1).

 The collectors 16, 17 and 18 are also interconnected by overflow partitions (not shown in FIG. 1) with filter elements (not shown in FIG. 1).

 And the bath 1 is equipped with a device for draining the electrolyte from its bottom (not shown in Fig. 1), made in the form of a screen not reaching the bottom of the bath 1, rigidly connected in its upper part to the upper edge of the overflow pipe 2 of the bath 1.

 The device operates as follows.

 In the initial state, in bath 1 are (for example), and in baths 3,6 and 9 there are no pendants with workpieces (not shown in Fig. 1).

 The level and composition (concentration of the main washable component) of the corresponding processing medium (for example, electrolyte and cold wash water) in baths 1 and 9, respectively, are normal.

 In collections 14 and 15 there are no purified and contaminated diluted electrolyte, respectively.

 In the collection 17 there is no contaminated water.

 The level of unpolluted demineralized (distilled) water supplied from its generator (accumulator) through the signaling regulator 59 is normal in the collection 18 (see the drawing) (the volume of this water is sufficient for multiple string washing operations in baths 3 and 6), as evidenced by the signal of the upper level of its controller-signaling device 59.

 Moreover, in the collection 16 there is also unpolluted demineralized (distilled) water that entered it (in this case) from the collection 18 through an overflow partition, and the volume of this water is sufficient for at least one operation of jet washing in the bath 3, o as evidenced by the signal of the lower level electrode of its sensor relay 57.

 Pumps 11, 24, 25, 26, 27, 28 and 29 are in the off state. The pressure of the jets (flow rate) of the washing liquid required in the technology in the baths 3 and 6 supplied by the pumps 27 and 29 is ensured by controlling the flow of water by devices 35 and 34, respectively installed on the bypass pipelines 50 and 48.

 After the end of the processing time of the parts in the bath 1 and their unloading from the latter, the parts 3 are loaded into the bath 3, on the surface of which the electrolyte carried out by them from the bath 1 is contained. Since demineralized water is already present in the collection 16 (at the initial stage of the module operation) (as evidenced by the signal at the output of its sensor-relay 57), the pump 27 and IM 30 are turned on for the duration of the parts unloading and the air-water mixture is supplied to the bathtub elements 4 3 through the pipeline 33.

At the same time, unpolluted demineralized water enters:
- through the pipeline 50 to the collector 16, thereby ensuring the return of unused water in this case, obtained due to the reduction of its flow rate by opening the device 35 on the bypass pipe 50;
- through the pipe 43 together with compressed air coming from its generator 31 through the pipe 32 and open IM 30 to the elements 4 of the bath 3, for the first operation of jet washing parts in the process of unloading (for example) from the bath 3 with a minimum amount of water, providing a flush (removal) up to 60-80% of electrolyte from the surface of parts.

 The contaminated diluted electrolyte formed during the jet washing process flows through line 5 to collector 15, as evidenced by the signal from its sensor-relay 56.

 After the time of washing parts in the bath 3, limited in this case by the time of unloading the parts, the MI 30 and the pump 27 are turned off.

 After that, the suspension with parts is loaded into the bath 6 and the pump 29 is turned on.

 In this case, demineralized water enters the elements 7 of the bath 6, ensuring the second operation of jet washing parts in the process of unloading (in this case) from the bath 6, with a maximum (for example) amount of water having a higher hydrodynamic pressure than in the bath 3 jets to the surface of the washed parts (the regulation of which was made previously by the device 34), which ensures removal of up to 95-98% of the electrolyte remaining on the surface of the latter after the first operation and the return of part of unused water through the pipe Code 48 in compilation 18.

 The contaminated flushing water generated during this jet washing is piped through the pipe 8 to the collector 17, as evidenced by the signal from its sensor-relay 58.

 After the time of jet washing in the bath 6, also limited by the time of unloading parts from it, the pump 29 is turned off.

 After the operation of jet washing in the bath 6, parts from the latter are moved and loaded into the bath 9 for their final washing.

 In this case, the remaining amount (2-5%) of the electrolyte removed from the parts from the bath 1 is removed in the bath 9 by immersion washing with vigorous stirring, for example, by supplying purified water from filter 13 or (and) its washing water.

 After the process of washing parts by immersion in the bath 9 and unloading them from the last bath, 1,3,6 and 9 are ready for galvanochemical processing of a new batch of parts.

 Moreover, the feature of the subsequent processing of parts, as well as the process of maintaining the level and composition of liquid processing media in baths 1 and 9, is as follows.

 1. The contaminated diluted electrolyte received in the collection 15 is subjected to filtration (mechanical, activated carbon, selective electrolysis, etc., depending on the type of electrolyte), for which the pump 26 of the collection 15 is turned on and the contaminated diluted electrolyte begins to circulate along the circuit: collection 15 - pump 26 - filter 20 - pipe 40 - device 22 - pipe 41 (and pipe 42, depending on the type of device 22) - collection 15 (as well as collection 14).

 After the end of the filtration time, determined by the volume of the diluted electrolyte being cleaned (in practice, up to 10 l) and the filter capacity 20, all the already purified diluted electrolyte with the help of the device 22 is moved through the pipe 42 to the collector 14, as evidenced by the signals of the sensor-relay 56 of the collector 15 (by which the pump 26 and the device 22 are switched off, if necessary) and the relay sensor 55 of the collection 14.

 After that, turn on the pump 24 of the collector 14 and the purified diluted electrolyte begins to circulate along the circuit: collector 14 - pump 24 - pipeline 36 - block 19 - pipeline 38 - collector 14.

 Block 19 carries out (using the methods of reverse osmosis, acid retardation, or electrodialysis using membrane devices based on perforated cation-selective membranes) the concentrated diluted electrolyte is concentrated by fractionation: concentrated electrolyte and purified water, the first of which is supplied via pipeline 38 in the collection 14, and the second (via pipeline 39) - in the collection 18, for reuse in jet washing operations.

 Monitoring the concentration of the main component of the electrolyte of the bath 1 is carried out by the sensor 60, by the signal of which (when the required concentration of the electrolyte discharged through the pipe 38 is reached), the pump 24 is turned off.

 If the electrolyte level in bath 1 has dropped below normal (due to removal by parts or the operation of airborne suction), then, at the signal of its sensor-relay 54, pump 25 of collector 14 is turned on and thereby the purified electrolyte is fed through line 37 to bath 1. possible excesses of the already polluted concentrated bath electrolyte from its bottom with the help of a pipe 2 not reaching the last screen enter the collector 15, which can be indicated by the signal from its sensor-relay 56, if the volume of the drained electrolyte is sufficient for this.

 2. The contaminated water received in the collector 17 is filtered (mechanical, activated carbon, etc.), for which the pump 28 of the collector 17 is turned on and the polluted water begins to circulate along the circuit: collector 17 - pump 28 - filter 21 - pipeline 44 - device 23 - pipeline to the collector 17 (and pipeline 45, depending on the type of device 23) - collector 17, as well as collector 16.

 After the end of the filtration time, determined by the volume of the water to be purified (in practice, up to 20 l) and the capacity of the filter 21, all already purified water enters the collector 16, as evidenced by the signals of the sensor-relay 57 of the collector 16, by which the pump 28 is turned off and device 21 (if necessary) and sensor relay 58 of the collection 17.

 3. The process of deep cleaning is carried out on the slightly washed main component of the electrolyte of the bath 1 of the washing water of the bath 9. At the same time, the pump 11 is turned on (periodically, depending on the number of batches of the bath 9, or continuously, during the work shift) and the washing water is circulated through circuit: bath 9 - drain pipe 10 - pump 11 - pipeline 51 - ion-exchange (or sorption, for example) columns (cartridges) 53 - pipe 52 - bath 9. And the replenishment of water losses of the bath 9, caused, in particular, by removal of its part and performed by the controller 12, a signaling device connected to a corresponding pipe (not indicated in the drawing) from the generator (drive) demineralized (distilled) water (not shown).

 In this case, the excess water generated in the bath 9 when loading parts or in the process of adding water from its generator can flow through an overflow pipe (not shown) in the collection 18.

4. After the processing time of the next (second in this case) suspension with parts in bath 1, their unloading from the last, and receipt of this suspension with parts in bath 3, they are washed in the same way as described above for this bath, with the difference that as washing liquid is used purified water from impurities and (or) STR containing the main washable component of the electrolyte, accumulated in the collection 16. For which are produced:
- inclusion of the pump 27;
- inclusion (if necessary) IM 30.

 Moreover, the diluted electrolyte is already more concentrated than in the first case through pipeline 5 to collector 15, which ultimately increases work efficiency (especially since it can be mixed with excess concentrated contaminated bath electrolyte 1) and reduces the energy consumption of unit 19 .

 The presence of overflow partitions with filter elements between the collectors 14 and 15, as well as between the collectors 16, 17 and 18, allows matching the volumes of the supplied and the liquid processing medium that is already in them and increases the reliability of the module as a whole, in case of failure of the filters 20, 21, which extends the functional and technological capabilities of the module. In addition, the supply of purified water (with the main washable component of bath electrolyte 1) from collector 16 can also be carried out before loading parts into bath 3, including for mixing with excess contaminated concentrated bath electrolyte 1 in collector 15.

Thus, the claimed device in comparison with the known, selected as a prototype, allows you to:
- significantly (up to 15-30%) reduce the specific costs of energy used in the concentration and separation of electrolyte fractions, by expanding the functional and technological capabilities of the module due to the use of different processing media with different flow characteristics at any stage of the module during string washing operations;
- to improve the quality of blast washing operations and the galvanochemical treatment process as a whole by providing the possibility of cleaning the electrolyte and washing water from impurities and (or) associated processing products, including in the conditions of the possible presence of excess processing medium in any of the collections, as well as failure of the cleaning circuits.

 The implementation of the proposed device is quite simple and does not meet fundamental difficulties.

 So, for example, as filters for cleaning contaminated electrolyte and water from impurities and (or) associated processing products in the device, standard installations with a set of mechanical and activated carbon cartridges can be used, as well as, in the case of an electrolyte, a selective flow or submersible electrolyzer type, placed in the collection of purified electrolyte or at the outlet of the corresponding pipeline.

 As a generator (source) of compressed air in the device, an autonomous oil-free blower or oil-free compressed air of a centralized line can be used.

 As actuators and devices for supplying fluid in two directions in the device, two- and three-way electromagnetic or pneumatic valves can be used, respectively, with the corresponding material of the flow part, or, in particular, in the latter case, the filter design itself.

 As devices for regulating the pressure of the washing liquid jets in the module, valve designs of both manual and remote execution can be used.

 As materials for the manufacture of collections of overflow partitions and filter elements in the device can be used vinyl plastic, polypropylene and filter chlorine fabric or polypropylene fabric, respectively.
