Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electroplating wastewater treatment, and particularly relates to a comprehensive electroplating wastewater treatment device. BACKGROUND

[0002] The electroplating industry produces a large amount of wastewater containing heavy metal ions (such as chromium, nickel, copper, zinc, etc.) and cyanide in the production process. If the wastewater is directly discharged without effective treatment, it will cause serious harm to the environment and human health. At present, the treatment process of electroplating wastewater mainly includes chemical precipitation method, ion exchange method, electrolysis method, etc. Among them, the chemical precipitation method is widely used due to its low cost and simple operation. This method makes heavy metal ions form flocculation precipitate by adding reagents (such as sodium hydroxide, sodium sulfide, etc.).

[0003] When the conventional electroplating wastewater is treated by the chemical precipitation method, the equipment for adding reagents has a fixed position, and the stirring of the wastewater is only the rotation of the stirring blade to drive the stirring of the wastewater. The reagents are too concentrated to fully contact with the wastewater, and the stirring blade only forms a vortex in the sedimentation tank, so that the stirring of the wastewater is poor and the flowability is poor, and it is difficult to realize the dynamic mixing of the wastewater and the reagents and the efficient separation of the precipitate. SUMMARY

[0004] The present application aims to provide a comprehensive electroplating wastewater treatment device to solve the technical problems proposed in the background.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

The components are used to drive the moving frame assembly to move along the outer support slide and to drive the filter plate agitation assembly to rotate. When the moving drive assembly moves to one end of the outer support slide where the switching assembly is located, the switching assembly can drive the moving drive assembly to establish a connection with the filter plate agitation assembly. When the moving drive assembly moves to one end of the outer support slide away from the switching assembly, the moving drive assembly can automatically disengage from the filter plate agitation assembly.

[0012] In one alternative embodiment: the floating dispensing assembly includes a dispensing execution unit, a dispensing drive unit, and a float.

Detailed Implementation

[0027] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0029] In one embodiment, such as Figures 1-4 As shown, a comprehensive electroplating wastewater treatment device includes a treatment sedimentation tank 100 and a mobile agent dispensing mechanism. Discharge ports 200 are provided on the outer walls of both ends of the treatment sedimentation tank 100, which are used to discharge treated clean water and settled waste residue, respectively. External support slides 300 are provided along the length of both sides of the treatment sedimentation tank 100, with a switching component 700 at one end of each slide 300, located at the waste residue discharge end of the treatment sedimentation tank 100. The mobile agent dispensing mechanism... The feed dispensing mechanism includes a movable frame assembly 400, a feed dispensing structure 500, a filter plate agitation assembly 600, and a forward drive assembly 800. The movable frame assembly 400 is disposed on the inner wall of the treatment sedimentation tank 100, and its two ends are slidably connected to two external support tracks 300. Multiple filter plate agitation assemblies 600 are rotatably disposed within the portion of the movable frame assembly 400 located inside the treatment sedimentation tank 100. The forward drive assembly 800 is disposed on the upper end of the movable frame assembly 400 and can establish a connection with the multiple filter plate agitation assemblies 600. Component 800 is used to drive the moving frame assembly 400 to move along the outer support slide 300 and to drive the filter plate agitation assembly 600 to rotate; when the forward moving drive assembly 800 moves to one end of the outer support slide 300 where the switching assembly 700 is located, the switching assembly 700 can drive the forward moving drive assembly 800 to establish a connection with the filter plate agitation assembly 600; when the forward moving drive assembly 800 moves to one end of the outer support slide 300 away from the switching assembly 700, the forward moving drive assembly 800 can automatically disengage from the filter plate agitation assembly 600; the agent The material dispensing structure 500 includes a material storage bin 510 and multiple floating dispensing components. The material storage bin 510 is located on top of the mobile frame assembly 400 and is used to store the material. The multiple floating dispensing components are located on the front side of the mobile frame assembly 400. The top of the floating dispensing components is connected to the material storage bin 510, and the bottom extends into the treatment sedimentation tank 100 and floats on the surface of the waste liquid in the treatment sedimentation tank 100. The floating dispensing components can move up and down by being agitated by the waste liquid and spread the material in the material storage bin 510 into the waste liquid.

[0030] In this embodiment of the invention, initially, both sets of discharge outlets 200 are closed, and a certain amount of electroplating wastewater accumulates in the sedimentation tank 100; the bottom of the floating dosing component floats on the surface of the electroplating wastewater; the forward drive component 800 operates and drives the moving frame component 400 and its agent dosing structure 500 and filter plate agitation component 600 to reciprocate along the outer support slide 300. When the forward drive component 800 is connected to multiple filter plate agitation components 600, the forward drive component 800... 0 also acts on the filter plate agitator 600 to make it rotate. The rotating filter plate agitator 600 agitates the electroplating wastewater in the sedimentation tank 100. The electroplating wastewater is agitated, and its liquid surface will change in a wave-like manner. The floating dosing component is moved up and down by the agitated electroplating wastewater. The floating dosing component can put the agent in the agent storage bin 510 into the electroplating wastewater. The agent mixes in the electroplating wastewater and flocculates the impurities in the electroplating wastewater to form flocs. The flocs settle due to their weight.

[0031] The moving speed of the forward drive assembly 800 driving the moving frame assembly 400 affects the rotational speed of the filter plate agitation assembly 600, thereby controlling the agitation amplitude of the electroplating wastewater. Furthermore, because the filter plate agitation assembly 600 moves with the moving frame assembly 400, the electroplating wastewater can be fully mixed with the additives. The agitation amplitude of the electroplating wastewater affects the up-and-down reciprocating speed of the floating dosing assembly. The floating dosing assembly can dispense the amount of additives according to the agitation amplitude and volume of the electroplating wastewater, ensuring that the additives match the volume of the electroplating wastewater and are dispensed at different locations. This improves the mixing of the electroplating wastewater and additives, avoids concentrated dispensing, and helps to fully flocculate impurities in the electroplating wastewater. When the mobile additive dispensing mechanism moves to the end of the outer support slide 300 away from the switching assembly 700, the plate surface of the filter plate agitation assembly 600 and the moving frame assembly 400... In a level state, the forward drive component 800 automatically disengages from the filter plate agitation component 600. As the forward drive component 800 moves with the moving frame component 400 toward the end where the switching component 700 is located, the filter plate agitation component 600 remains stable and moves in a filtering manner, allowing the electroplating wastewater to be agitated in a jet manner. When the mobile agent dispensing mechanism moves to the end of the outer support slide 300 near the switching component 700, the switching component 700 drives the forward drive component 800 to establish a connection with the filter plate agitation component 600. Therefore, when the mobile agent dispensing mechanism moves toward the end away from the switching component 700, the filter plate agitation component 600 moves with the forward drive component 800 in a rotating manner. Thus, the filter plate agitation component 600 acts on the electroplating wastewater in two alternating agitation modes, which can make the electroplating wastewater and the agent mix thoroughly and evenly.

[0032] After the filter plate agitator 600 and the electroplating wastewater and reagents are fully mixed, the forward drive component 800 stops working, and the electroplating wastewater enters the settling stage. The flocculated material gradually settles to the bottom of the treatment sedimentation tank 100. At this time, the mobile reagent dispensing mechanism is located at the end away from the switching component 700, and the plate surface of the filter plate agitator 600 is flush with the moving frame component 400. The discharge port 200 for clean water is opened, and the clean water is discharged from the discharge port 200. The filter plate agitator 600 can prevent the flocculated material from flowing out with the clean water, thus achieving the separation of flocculated material and clean water. After the clean water is discharged, another set of discharge ports 200 is opened, and the mobile reagent dispensing mechanism moves toward the switching component 700. The filter plate agitator 600 remains stable and can push the flocculated material to the discharge port 200 for easy discharge.

[0033] In one embodiment, such as Figures 1-4 As shown, the movable frame assembly 400 includes an upper support frame 410 and a lower frame 430. The upper support frame 410 is slidably connected at both ends to two outer support tracks 300. The lower frame 430 is located at the bottom of the upper support frame 410 and inside the treatment sedimentation tank 100. The side of the lower frame 430 is slidably in contact with the inner wall of the treatment sedimentation tank 100. The inner side of the lower frame 430 has multiple equally spaced partition rods 420, with a frame opening formed between adjacent partition rods 420. The filter plate agitation assembly 600 corresponds to this. The frame is rotated within the frame opening; in this embodiment of the invention, the side of the lower frame 430 contacts the outer wall of the treatment sedimentation tank 100, preventing the flocculent from passing through the gap between the lower frame 430 and the outer wall of the treatment sedimentation tank 100 during the separation of flocculent and purified water; multiple filter plate agitation assemblies 600 rotate synchronously to form multiple moving agitation vortices, with two adjacent vortices contacting each other to achieve mixing of the reagent and electroplating wastewater; the filter plate agitation assembly 600 sealing the frame opening can prevent the flocculent from passing through the frame opening, thus achieving the separation of flocculent and purified water.

[0034] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the filter plate agitation assembly 600 includes an agitation main shaft 610 and a filter plate portion 620 disposed thereon. The filter plate portion 620 can cover the frame opening. A driven bevel gear 630 is disposed on the top of the agitation main shaft 610. The forward drive assembly 800 includes a linkage shaft 810 and two synchronous moving assemblies 820. The linkage shaft 810 is laterally rotatable on the upper support frame 410. A plurality of driving bevel gears 830 are disposed on the linkage shaft 810, and the plurality of driving bevel gears 830 mesh with corresponding driven bevel gears 630. The two synchronous moving assemblies 820 are respectively disposed at both ends of the upper support frame 410 and are detachably connected to both ends of the linkage shaft 810. In this embodiment of the invention, when the movable agent dispensing mechanism moves toward the switching assembly 700, when the synchronous moving assembly 820 is connected to the end of the linkage shaft 810, the synchronous moving assembly 820... The 0 mechanism operates and drives the moving frame assembly 400 to move along the outer support slide 300. The synchronous moving assembly 820 acts on the linkage shaft 810 to make it rotate. The linkage shaft 810, through the meshing of the driving bevel gear 830 and the driven bevel gear 630, causes multiple agitator shafts 610 to rotate. The filter plate section 620 follows the rotation of the agitator shaft 610 and agitates the electroplating wastewater. The rotation speeds of two adjacent agitator shafts 610 are opposite, so that the vortices formed by the rotation of two adjacent filter plate sections 620 come into contact with each other and form convection, improving the mixing effect. Before the mobile agent dispensing mechanism moves away from the switching assembly 700, the switching assembly 700 acts on the end of the linkage shaft 810 and disengages it from the synchronous moving assembly 820, so that the filter plate section 620 moves while maintaining the sealed frame opening. This allows the electroplating wastewater to pass through the filter plate section 620 in a jet manner and agitate the electroplating wastewater.

[0035] In one embodiment, such as Figures 1-7As shown, the upper end face of the outer support slide 300 is provided with a movable rack portion 310 along its length, and the lower end face of the outer support slide 300 has an oval groove 320. The synchronous moving assembly 820 includes a connecting sleeve 840, a switching guide rod 870, and a synchronous motor 880. The connecting sleeve 840 is axially slidable at the end of the linkage shaft 810. A linkage gear 850 is provided on the connecting sleeve 840, and the linkage gear 850 is connected to the end of the upper support frame 410 through a release spring 841. The synchronous motor 880 is provided on the upper support frame 410, and its output end has a forward gear 890. The forward gear 890 and the linkage gear 850 can be disengaged and meshed. The forward gear 890 is also connected to the movable rack portion located on the same side. 310 engagement, the top of the switching guide rod 870 is provided with a rotating ring 860 and the rotating ring 860 is rotatably sleeved on the connecting sleeve 840, the switching guide rod 870 extends into the oval groove 320 and moves along the oval groove 320; in this embodiment of the invention, the synchronous motor 880 works and drives the forward gear 890 to rotate, the forward gear 890 moves along the outer support slide 300 by meshing with the moving rack part 310; when the switching guide rod 870 is on the side of the oval groove 320 close to the moving frame assembly 400, the linkage gear 850 and the forward gear 890 are in a meshing state, the forward gear 890 also moves along the connecting sleeve 840 by meshing with the linkage gear 850. 40 and linkage shaft 810 rotate; when the switching guide rod 870 is on the side of the oblong channel 320 away from the moving frame assembly 400, the linkage gear 850 and the forward gear 890 disengage, so when the movable dispensing mechanism moves along the outer support slide 300, the linkage shaft 810 will not rotate; when the synchronous moving assembly 820 is at the switching assembly 700, the switching assembly 700 acts on the switching guide rod 870 and moves its bottom from the side of the oblong channel 320 away from the moving frame assembly 400 along its end to the side of the oblong channel 320 close to the moving frame assembly 400; thus, the switching guide rod 870 moves in the axial direction of the linkage shaft 810, and the switching guide rod 870 moves through the rotating ring 8 60 acts on the connecting sleeve 840 to move it axially, thereby engaging the linkage gear 850 with the forward gear 890; when the synchronous moving component 820 is at the end of the outer support slide 300 away from the switching component 700, the switching guide rod 870 is at the round end of the oblong groove 320, and the release spring 841 is always in a compressed state and has a tendency to push the connecting sleeve 840 to move away from the moving frame component 400. When the synchronous moving component 820 moves back along the outer support slide 300, the switching guide rod 870 moves from the side of the oblong groove 320 close to the moving frame component 400 to the side of the oblong groove 320 away from the moving frame component 400, thereby automatically disengaging the linkage gear 850 from the forward gear 890.

[0036] In one embodiment, such as Figures 1-7 As shown, a freely rotatable abutment roller 871 is provided at the middle position of the switching guide rod 870. A front protrusion 330 is fixed at the end of the outer support slide 300 near the switching assembly 700. The switching assembly 700 includes an outer pressure rod 710, a movable rod 720, and a tail plate 730. The movable rod 720 can slide through the front protrusion 330, and its sliding direction is the same as the width direction of the outer support slide 300. The outer pressure rod 710 is located at the end of the movable rod 720 away from the treatment sedimentation tank 100. The outer pressure rod 710 is inclined outward toward the other end of the outer support slide 300. The tail plate 730 is located at the other end of the outer pressure rod 710, and the tail plate 730 and the front protrusion 330 are connected by a switching spring 740. The elastic coefficient of the switching spring 740 is greater than the elastic coefficient of the release spring 841. In this embodiment of the invention, when the mobile agent dispensing mechanism approaches the switching assembly... When part 700 is in operation, since the bottom end of the switching guide rod 870 is on the side of the oblong channel 320 away from the treatment sedimentation tank 100, the abutment roller 871 abuts against the side of the external pressure rod 710 facing the external support slide 300. As the switching guide rod 870 approaches the end of the oblong channel 320, the abutment roller 871 pushes the external pressure rod 710 outward, the movable rod 720 moves relative to the front protrusion 330, and the tail plate 730 compresses the switching spring 740. When the end of the switching guide rod 870 moves to the round end of the oblong channel 320, since the elastic force of the switching spring 740 is greater than the elastic force of the release spring 841, the external pressure rod 710 applies a pushing force to the abutment roller 871, so that the bottom of the switching guide rod 870 moves smoothly to the side of the oblong channel 320 close to the treatment sedimentation tank 100. The switching guide rod 870 drives the connecting sleeve 840 to move and makes the linkage gear 850 mesh with the forward gear 890.

[0037] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9As shown, the floating dispensing assembly includes a dispensing execution unit 520, a dispensing drive unit 530, and a float 540. The top of the dispensing execution unit 520 is connected to the agent storage bin 510, and its bottom is open. The bottom of the dispensing drive unit 530 is slidably engaged with a corresponding partition rod 420. The float 540 is located at the bottom of the dispensing drive unit 530, and the top of the dispensing drive unit 530 is connected to the dispensing execution unit 520. When the dispensing execution unit 520 moves vertically along the partition rod 420, it can act on the dispensing execution unit 520 to dispense the agent in the agent storage bin 510 into the treatment sedimentation tank 100. In this embodiment of the invention, the electroplating wastewater is stirred... During the process, the liquid level is constantly changing, and the rate and height of this change are determined by the stirring speed. Because the float 540 floats on the surface of the electroplating wastewater, the dispensing drive unit 530 moves up and down repeatedly. The moving dispensing drive unit 530 acts on the dispensing execution unit 520, which dispenses the agent from the agent storage bin 510 into the treatment sedimentation tank 100. The frequency of dispensing is determined by the speed of the dispensing drive unit 530's up-and-down reciprocating movement, which in turn is determined by the rate of change of the electroplating wastewater's liquid level. Thus, the amount of agent dispensed can be adapted to the amount of electroplating wastewater and the stirring amplitude, improving mixing efficiency and avoiding waste caused by insufficient agent, inadequate impurity removal, or excessive dosage.

[0038] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9As shown, the dispensing execution unit 520 includes a dispensing conveyor cylinder 521, a dispensing conveyor shaft 522, a dispensing roller body 523, and an upper guide pipe 525. The arc apex of the dispensing conveyor cylinder 521 is connected to the outer wall of the agent storage bin 510 through the upper guide pipe 525. The dispensing conveyor shaft 522 is rotatably disposed inside the dispensing conveyor cylinder 521, with one end extending to the outside of the dispensing conveyor cylinder 521. A dispensing gear 527 is provided at the end of the dispensing conveyor shaft 522. The dispensing roller body 523 is disposed on the dispensing conveyor shaft 522, and has multiple [features] on its circumferential outer wall. The delivery chamber 524; the delivery conveying cylinder 521 has a delivery port 526 at its arc bottom; the delivery drive unit 530 includes a delivery rack 531 and a delivery spring 534. The lower end of the delivery rack 531 is slidably engaged with the spacer 420 via a lower slider 532. The float 540 is fixed to the bottom end of the delivery rack 531. The delivery rack 531 can slide through the guide seat 411 located on the side of the upper support frame 410. A lower pressure plate 533 is provided at the top of the delivery rack 531, and the lower pressure plate 533 is connected to the guide seat 411 via the delivery spring 534. The feeding rack 531 meshes with the feeding gear 527. In this embodiment of the invention, the elastic force generated by the deformation of the feeding spring 534 and the upward thrust of the feeding rack 531 on the float 540 due to the change in the surface of the electroplating wastewater cause the feeding rack 531 to move vertically back and forth along the partition rod 420. The feeding rack 531, through meshing with the feeding gear 527, causes the feeding conveying shaft 522 and the feeding roller 523 to rotate. Multiple feeding chambers 524 rotate inside the feeding conveying cylinder 521, and the agent inside the agent storage bin 510 is transported through... The upper guide pipe 525 enters the feeding conveyor cylinder 521 and falls into the feeding chamber 524. The feeding chamber 524 rotates with the feeding roller 523 and can alternately correspond to the feeding port 526 and the upper guide pipe 525. The agent in the feeding chamber 524 is discharged through the feeding port 526. The rotation speed of the feeding roller 523 determines the frequency at which the feeding chamber 524 rotates to the corresponding position of the feeding port 526, thereby controlling the frequency of agent feeding. The dosage of agent fed into the feeding chamber 524 is the same each time, which can effectively adapt to the amplitude of the agitation of the electroplating wastewater.

[0039] The above embodiment provides a comprehensive treatment device for electroplating wastewater, the working principle of which is as follows:

[0040] 1. Initial state and wastewater treatment preparation

[0041] Wastewater accumulation: Electroplating wastewater is injected into the treatment sedimentation tank 100, and the discharge outlets 200 at both ends are closed, and a certain amount of wastewater is accumulated in the tank.

[0042] Floating dosing component positioning: The bottom of the floating dosing component of the agent dosing structure 500 floats on the surface of the wastewater, and the agent storage bin 510 pre-stores flocculants and other treatment agents.

[0043] 2. Mobile agent dispensing and wastewater agitation

[0044] Drive and movement: The forward drive assembly 800 is started, and the forward gear 890 is driven by the synchronous motor 880 to mesh with the moving rack 310, thereby driving the moving frame assembly 400 to reciprocate along the outer support slide 300.

[0045] Switch working mode:

[0046] When approaching the switching component 700: the switching guide rod 870 is acted upon by the external pressure rod 710, which pushes the connecting sleeve 840 to compress and release the spring 841. The linkage gear 850 meshes with the forward gear 890, and the linkage rod shaft 810 rotates, driving the filter plate stirring component 600 to rotate through the bevel gear set 830 / 630.

[0047] Stirring the wastewater: The filter plate section 620 rotates to form a vortex, and the adjacent filter plate sections 620 rotate in opposite directions to generate convection, which promotes the mixing of wastewater and agents.

[0048] Additive Dispensing: The wastewater agitates and pushes the float 540 to move up and down, the dispensing rack 531 drives the dispensing gear 527 to rotate, and the dispensing chamber 524 of the dispensing roller 523 periodically and evenly sprinkles the additive into the wastewater through the dispensing port 526.

[0049] When away from the switching component 700: the switching guide rod 870 slides to the far end of the oval channel 320, the linkage gear 850 disengages, the filter plate part 620 remains stationary, and the moving frame component 400 pushes the wastewater to form a jet agitation, enhancing the mixing effect.

[0050] 3. Separation of flocculation and settling

[0051] Flocculation reaction: After the agent and wastewater are fully mixed, impurities flocculate into flocs and settle.

[0052] Clean water discharge: The moving frame assembly 400 stops at the end furthest from the switching assembly 700, and the filter plate section 620 is flush with the closed frame opening. The clean water discharge port 200 is opened, the filter plate blocks flocculent matter, and the clean water is discharged.

[0053] Waste residue cleaning: Open the waste residue discharge port 200, the moving frame assembly 400 moves to the switching assembly 700, and the filter plate section 620 pushes the flocculent to the discharge port 200 for centralized discharge.

[0054] 4. Synergistic effect of key components

[0055] Adaptive dosing: The floating dosing component dynamically adjusts the dosing frequency according to the amplitude of wastewater movement to ensure that the dosage matches the wastewater treatment requirements.

[0056] Dual-mode agitation: Rotary agitation and jet filtration alternate to improve mixing uniformity.

[0057] Mechanical linkage design: The automatic engagement / disengagement mechanism of the switching component 700 and the synchronous moving component 820 enables seamless switching of working modes.

[0058] 5. Summary of Advantages

[0059] High-efficiency mixing: The multi-filter plate section 620 works together to create convection, avoiding concentrated addition of agents.

[0060] Energy-saving and precise: Wastewater-driven agent dispensing reduces additional energy consumption.

[0061] High degree of automation: The mechanical structure can switch working states autonomously, reducing the need for manual intervention.

[0062] This equipment combines mechanical linkage with fluid dynamics to achieve efficient flocculation, separation and purification of electroplating wastewater, making it suitable for large-scale wastewater treatment scenarios.
