Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a device and method for deep treatment of recycled electronic electroplating wastewater. Background Art

[0002] The sources of electroplating wastewater are generally plated parts cleaning water, waste plating solution and other wastewater. The water quality of electroplating wastewater is complex and its composition is difficult to control. Electroplating wastewater contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver and cyanide.

[0003] At present, chemical precipitation method is often used for deep treatment of electroplating wastewater:

[0004] By adding precipitants to react with metal ions in wastewater to generate water-insoluble precipitates, heavy metals are separated. This method is simple to operate, economical and effective, and has a high removal rate for heavy metal ions.

[0005] Specific chemical precipitation methods include neutralization precipitation (adding alkali for neutralization reaction to generate hydroxide precipitate), sulfide precipitation (adding sulfide to generate sulfide precipitate) and chelate precipitation (using high molecular weight heavy metal capture precipitant to generate water-insoluble chelate salt), so as to complete the deep treatment of electroplating wastewater.

[0006] A patent application with reference publication number CN110845049A discloses an electroplating wastewater treatment box, in which electroplating wastewater to be treated and reagents for treating electroplating wastewater are input into the box body through a feeding port, and a stirring motor drives a plurality of stirring blades through a stirring shaft to stir the electroplating wastewater to be treated and the reagents for treating electroplating wastewater, and the sediment formed after the electroplating wastewater to be treated and the reagents for treating electroplating wastewater are fully reacted falls onto a receiving box.

[0007] At present, when electroplating wastewater is deeply treated by chemical precipitation, the precipitant is mostly directly put into the treatment box to contact with the electroplating wastewater to complete mixed precipitation. For example, the above-mentioned wastewater treatment box injects reagents into the box body through the feeding port, and then stirs the reagents and wastewater through the stirring shaft to complete mixing. Since the wastewater treatment reagents are directly added to the treatment box, the reagents and wastewater cannot fully contact and mix with electroplating wastewater of different liquid level heights, and the reagents and wastewater cannot be accurately and controllably contacted and mixed, which affects the effect of the deep treatment of the wastewater, resulting in the treatment of a large amount of electroplating wastewater failing to meet the demand, which is time-consuming and labor-intensive, affecting the efficiency of wastewater treatment, and increasing the subsequent treatment cost investment.

[0074] The lifting screw 4 is rotatably arranged at the bottom of the top cover 2. An accordion protective cover can be sleeved on the outside of the lifting screw 4. Specifically, a split accordion protective cover is arranged to isolate and protect the lifting screw 4. In order to improve the stability of the lifting screw 4, a bracket for limiting the lifting screw 4 can be arranged in the processing tank 1 to keep its rotation stable. A screw nut 5 is arranged on the transmission sleeve outside the lifting screw 4, and a lifting motor 6 connected to the lifting screw 4 is arranged on the top cover 2. Sliding areas 7 are symmetrically opened on both sides of the lifting screw 4. A cleaning piece for cleaning the intercepting piece is arranged at the bottom of the lifting screw 4;

[0075] It should be noted that: when the extrusion piece 8 is controlled up and down: the lifting motor 6 is started to control the rotation of the lifting screw 4, and the linkage screw nut 5 completes the up and down movement under the control of the lifting screw 4, which can drive the extrusion piece 8 to follow the up and down movement. At the same time, the extrusion piece 8 can be stably lifted up and down by the restriction of the guide rod, so that the overall electroplating wastewater treatment can be carried out stably;

[0076] like Figure 4 and Figure 8 As shown, the extrusion piece 8 is fixedly sleeved outside the screw nut 5, and the extrusion piece 8 is in sliding sealing contact with the inner wall of the processing tank 1. Two guide rods are symmetrically arranged on both sides of the processing tank 1. The two guide rods slide through the extrusion piece 8 correspondingly.

The four shielding mechanisms cooperate with the up and down movement of the extrusion member 8 to complete the switching opening and closing action of the four mixing mechanisms;

[0079] In the embodiment of the present invention, Figure 5 and Figure 6 As shown, the interceptor comprises:

[0080] A circular filter cartridge 10 is connected and arranged at the bottom of the isolating member 3. A plurality of filter holes are arranged in a circular array around the circular filter cartridge 10. A slag discharge pipe is connected and installed at the bottom of the circular filter cartridge 10. A pump for extracting slag is arranged at the end of the slag discharge pipe. The slag discharge pipe passes through the bottom of the processing tank 1.

[0081] The sealing ring 11 is slidably sleeved on the outside of the circular filter cartridge 10 to complete active blocking. An electric push rod connected to the sealing ring 11 is installed on one side of the bottom of the treatment tank 1 through a bracket. The electric push rod controls the sealing ring 11 to move up and down to complete the opening and closing of the circular filter cartridge 10 in working state.

[0082] The cleaning kit includes:

[0083] The cleaning shaft 12 is fixedly arranged at the bottom of the lifting screw 4;

[0084] A cleaning scraper 13 is arranged on one side of the cleaning shaft 12 and contacts the inner wall of the circular filter cartridge 10. The cleaning scraper 13 is used to scrape and clean the circular filter cartridge 10.

[0085] It is worth noting that: under normal conditions, the sealing ring 11 moves up to block the circular filter cartridge 10 and keep it closed. After the subsequent reaction is completed, the electric push rod is controlled to drive the sealing ring 11 to move down to release the circular filter cartridge 10. At this time, the sediment in the electroplating wastewater is intercepted and filtered through the circular filter cartridge 10, and the clean electroplating wastewater is discharged through the discharge pipe. Subsequently, the sediment in the circular filter cartridge 10 is discharged through the slag discharge pipe to avoid the accumulation of sediment. At the same time, when the circular filter cartridge 10 is closed, when the lifting screw 4 rotates, the linkage cleaning shaft 12 rotates accordingly, and the cleaning scraper 13 can scrape and clean the inner wall of the circular filter cartridge 10 to maintain the cleanliness of the circular filter cartridge 10 and reduce the difficulty of cleaning and maintenance. At the same time, the sealing ring 11 can complete the cleaning work of the circular filter cartridge 10 during a single opening and closing process;

[0089] Among them, electrical components such as the lifting motor 6 are connected to switches through wires, and the switches are electrically connected to a controller. The specific structure of the controller is not limited. An absolute encoder is installed on the lifting motor 6 to accurately position the lifting motor 6.

[0090] Embodiment 2: Based on the mixing mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the mixing mechanism.

[0091] like Fig.10 and Fig.12 As shown, each mixing mechanism includes:

[0092] The transmission chamber 16 is hidden at the top of the extrusion member 8. A sealing cover 17 is detachably mounted on the top of the transmission chamber 16. A driving shaft 18 is rotatably arranged in the transmission chamber 16 toward the flow area 9. A first bevel gear 19 is fixedly sleeved outside the driving shaft 18.

[0093] like Fig.13 and Fig.14 As shown, the transmission shaft 20 is rotatably arranged on the sealing cover 17, a second bevel gear 21 meshing with the first bevel gear 19 is arranged at the bottom of the transmission shaft 20, a connecting gear 22 meshing with the driving gear ring 14 is rotatably sleeved on the outside of the transmission shaft 20, a dust cover can be arranged on the connecting gear 22 and the driving gear ring 14 to complete the isolation and protection function, and an inner gear ring 23 is hidden on the inner wall of the connecting gear 22;

[0094] Each mixing unit includes:

[0095] The rectangular cavity 24 is arranged in the circulation area 9 through a bracket. A circulation area is arranged in the rectangular cavity 24 to allow the treatment reagent to flow. A plurality of nozzles are arranged on both sides of the inner wall of the rectangular cavity 24. A No. 1 pipe 25 is installed on one side of the rectangular cavity 24 to complete the treatment agent delivery work of the plurality of nozzles through the No. 1 pipe 25.

[0096] Two stirring shafts 26 are symmetrically arranged on both sides of the rectangular cavity 24;

[0097] The first gear 27 is fixedly arranged at the front end of the driving shaft 18, and the front end of the driving shaft 18 rotates and passes through the rectangular cavity 24. The second gears 28 are fixedly sleeved at one end of the two stirring shafts 26. The two second gears 28 are meshed with the first gear 27, and a protective cover covering the first gear 27 and the two second gears 28 is arranged in the rectangular cavity 24;

[0098] Each mixing unit also includes:

[0099] The extrusion area 29 is arranged at the top of the transmission shaft 20, and a second pipe 30 is arranged at the top of the extrusion area 29 for sealing and rotation;

[0100] Multiple hidden areas 31 are arranged in a circular array around the transmission shaft 20. The multiple hidden areas 31 are interconnected with the extrusion area 29. Specifically, interconnected channels are arranged on the multiple hidden areas 31. A connecting tooth 32 is installed in a sliding seal in each hidden area 31. A reset spring is arranged between each connecting tooth 32 and the hidden area 31. The power connection is completed by the engagement of the connecting tooth 32 with the inner gear ring 23. The connecting tooth 32 is pulled by the reset spring to hide in the hidden area 31.

[0101] It is worth noting that when the electroplating wastewater is stirred: by providing a mixing mechanism, when the blocking plate 36 of the shielding mechanism is opened, the blocking plate 36 drives the piston 39 to move upward in the trigger chamber 38, and sends the medium in the trigger chamber 38 into the second tube 30 through the third tube 40, and then the medium enters the extrusion area 29, forcing the connecting teeth 32 in the multiple hidden areas 31 to extend and engage with the inner gear ring 23 to complete the connection. Therefore, in the open state, the connecting gear 22 of the circulation area 9 is in a connected state, and in the closed state, the connecting gear 22 of the circulation area 9 is in a disconnected state, avoiding the problem of increased resistance due to idling, ensuring stable power output, and the subsequent rotation of the lifting screw 4 The gear ring 14 is driven to rotate step by step, and the connecting gear 22 in the open state is controlled to rotate through the driving gear ring 14, and the power is transmitted to the first gear 27 through the first bevel gear 19 and the second bevel gear 21, and the two second gears 28 and the stirring shaft 26 are linked to rotate, so that the circulation area 9 in the open state can be stirred and mixed, thereby improving the contact effect between the treatment agent and the electroplating wastewater. After the subsequent circulation area 9 is closed, the piston 39 is reset in the trigger chamber 38, and the connecting tooth 32 is reset again to the hidden area 31 through the reset spring control to disconnect the power connection, so that the working state of the connecting gear 22 can be linked with the blocking plate 36, reducing the control difficulty;

[0103] The annular cavity 33 is arranged at the bottom of the top cover 2, a delivery pipe is connected and installed at the top of the annular cavity 33, and a feed pump for extracting materials is arranged at the end of the delivery pipe;

[0104] A plurality of interconnecting pipes 34 are arranged at the bottom of the annular cavity 33 to realize active feeding of the four mixing mechanisms;

[0105] It is worth noting that when the mixing mechanism switches the material: the required type of treatment agent is fed into the annular cavity 33 through the feeding mechanism and the conveying pipe, and then transferred to the No. 4 pipe 44 of each shielding mechanism through the interconnecting pipe 34. Under normal circumstances, the dislocation blocking of the No. 4 pipe 44 and the No. 5 pipe 45 is completed through the switching block 42 to avoid leakage. When the blocking plate 36 moves to open the flow area 9, the piston 39 is pushed to move, and the linkage switching block 42 moves up in the switching chamber 41, so that the feeding area 43 of the switching block 42 is interconnected with the No. 4 pipe 44 and the No. 5 pipe 45, and then the treatment agent is fed into the No. 1 pipe 25 through the No. 5 pipe 45, and finally the treatment agent is sprayed into the open flow area 9 through multiple nozzles. Since the opening state of the switching chamber 41 is also linked with the blocking plate 36, after the blocking plate 36 is opened, the feeding mechanism and the mixing mechanism can be opened, so that the output of the treatment agent and the dialing operation can be carried out synchronously, thereby improving the processing efficiency.

Specifically, the interconnection pipe 34 is connected with the No. 4 pipe 44 through a flexible pipeline, and the No. 5 pipe 45 is connected with the No. 1 pipe 25 through a pipeline. At the same time, a pipeline installation channel is reserved on the extrusion part 8, and the pipeline between the interconnection pipe 34 and the No. 5 pipe 45 is pre-buried through the pipeline installation channel to avoid interference with the blocking state of the circulation area 9;

[0113] It is worth mentioning that when the flow area 9 of the extrusion piece 8 is switched to be blocked: a blocking mechanism is provided, since the four blocking mechanisms are staggered with the four flow areas 9 on the extrusion piece 8, under normal circumstances, the blocking spring pushes the blocking plate 36 to move to the flow area 9 to complete active blocking, thereby ensuring the closed state of the extrusion piece 8. When the extrusion piece 8 moves downward, the electroplating wastewater squeezes the blocking plates 36 of two of the blocking mechanisms and forces them to be pushed open by the water pressure to open the flow area 9 and compress the blocking spring. Since the other two blocking plates 36 are located below the extrusion piece 8, when the extrusion piece 8 moves downward, the water pressure causes the blocking plates 36 of the two blocking mechanisms to remain tightly attached to the corresponding flow areas 9 to remain blocked. Therefore, when the extrusion piece 8 continues to move downward, the electroplating wastewater in the area below the extrusion piece 8 in the treatment tank 1 The treatment agent is collected in two open circulation areas 9, and the treatment agent is simultaneously sent into the two open circulation areas 9 to continuously contact with the electroplating wastewater, and a stirring mixing effect is provided through the mixing mechanism, thereby further ensuring sufficient contact between the treatment agent and the electroplating wastewater. When the extrusion member 8 moves upward, the originally opened shielding mechanism is closed by the water pressure, and the originally closed shielding mechanism is opened, and the electroplating wastewater above the extrusion member 8 is controlled to be collected in the two open circulation areas 9. With such a design, when the extrusion member 8 moves up and down, it can first complete the up and down squeezing turbulence of the electroplating wastewater in the treatment tank 1, thereby improving the flow effect of the electroplating wastewater, and the control circulation area 9 can be switched to open, thereby forcing the electroplating wastewater to always be collected in the two circulation areas 9 to complete the transportation, thereby further improving the contact effect between the treatment agent and the electroplating wastewater.

[0114] Embodiment 4: A method for deep treatment of electronic electroplating wastewater for reuse, the deep treatment method specifically comprising the following steps:

[0115] Step 1, first connect the delivery pipe with the treatment agent required for electroplating wastewater;

[0116] Step 2, then feeding the electroplating wastewater into the treatment tank 1 through the feed pipe;

[0117] Step 3: By providing four circulation areas 9, the circulation guidance of the electroplating wastewater above and below the extrusion piece 8 in the treatment tank 1 can be completed;

[0118] Step 4: Four shielding mechanisms are staggered on the four circulation areas 9, and the four shielding mechanisms are interchanged during the up and down movement of the extruder 8. The treating agent is released into the circulation area 9 through the mixing mechanism and stirring and stirring operations are provided, so that the treating agent can be fully contacted and mixed with the electroplating wastewater.

[0119] The present invention provides a device and method for deep treatment of electronic electroplating wastewater reuse. The specific working principle is as follows: first, the delivery pipe is connected with the treatment agent required for the electroplating wastewater, and then the electroplating wastewater is fed into the treatment tank 1 through the feeding pipe, and then the lifting motor 6 is started to control the screw nut 5 and the extrusion piece 8 to move up and down in the treatment tank 1. By providing four circulation areas 9, the circulation guidance of the electroplating wastewater above and below the extrusion piece 8 in the treatment tank 1 can be completed. When the extrusion piece 8 moves up and down, the mixing mechanism is synchronously triggered to complete the stirring and mixing, and the electroplating wastewater with different liquid level heights in the treatment tank 1 can be moved, which further ensures the full contact between the treatment agent and the electroplating wastewater. At the same time, four shielding mechanisms are staggered on the four circulation areas 9, and then when the extrusion piece 8 moves down, Due to the squeezing of the electroplating wastewater, two circulation areas 9 are opened and the other two circulation areas 9 are closed, forcing the electroplating wastewater in the treatment tank 1 to flow out through the two opened circulation areas 9 under pressure. Under this action, the mixing mechanisms in the two opened circulation areas 9 are synchronously triggered to release the treatment agent into the circulation areas 9 and provide stirring and stirring operations, so that the treatment agent can be fully contacted and mixed with the electroplating wastewater. When the extrusion member 8 moves up, the four shielding mechanisms are interchanged. With this design, the treatment agent can be fully released through the up and down movement of the extrusion member 8, and the treatment agent is forced to contact and fully mix with the electroplating wastewater at different liquid levels in the treatment tank 1, thereby improving the purification efficiency. At the same time, the depth of treatment accuracy can be controlled to avoid the problem of unqualified electroplating wastewater treatment and reduce the treatment cost.
