Description

Technical Field

[0001] The invention relates to the technical field of electroplating wastewater treatment, and in particular to nickel electroplating wastewater treatment equipment for removing sludge. Background Art

[0002] Electroplating sludge refers to the precipitate produced during the electroplating wastewater treatment process, which is mainly composed of heavy metal hydroxides such as copper and chromium. The composition is very complex. Due to the large amount of electroplating wastewater and its complex composition, it needs to be treated to meet the indicators before it can be discharged. In addition, a lot of electroplating sludge will be formed in the electroplating wastewater process. These electroplating sludges are highly stable and not easy to treat.

[0003] The existing electroplating wastewater is often treated by chemical precipitation, which will produce a large amount of electroplating sludge. The electroplating sludge will settle to the bottom of the container during wastewater treatment, which is inconvenient to clean. During cleaning, the electroplating sludge is easily mixed with the electroplating wastewater on the upper layer, thereby reducing the chemical precipitation effect of the electroplating wastewater and affecting the subsequent treatment of the electroplating wastewater, resulting in a decrease in the treatment efficiency of the electroplating wastewater.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] The present invention discloses a nickel electroplating wastewater treatment device for removing sludge, which is mainly used in scenarios where the electroplating sludge is easily mixed with the upper layer of electroplating wastewater during cleaning, thereby reducing the chemical precipitation effect of the electroplating wastewater.

[0027] Reference Figure 1-8A nickel electroplating wastewater treatment device for sludge removal includes a treatment box 2, a second motor 33 is fixedly connected to the bottom of the treatment box 2, and the output shaft of the second motor 33 is connected to a screw rod 31 through a coupling, the top of the screw rod 31 is fixedly connected to a limit plate 30, the outer wall of the screw rod 31 is provided with a partition plate 19, and the outer wall of the partition plate 19 contacts the inner wall of the treatment box 2, the top of the partition plate 19 is provided with two mounting openings 18, and the bottom of the inner wall of the two mounting openings 18 is evenly spaced with a plurality of sedimentation holes 16, the inner walls of both sides of the two mounting openings 18 are fixedly connected to two guide rods 25, and the outer walls of the two guide rods 25 inside the same mounting opening 18 are movably connected to the same mounting seat 26, The inner walls on both sides of the two mounting seats 26 are fixedly connected to the same mounting rod 21, and the outer walls of the two mounting rods 21 are movably connected to the blocking plate 20. Two connecting ports are provided on the outer walls of one side of the two blocking plates 20. Two mounting grooves are provided on the top of the partition plate 19. The bottom of the inner walls of the two mounting grooves are fixedly connected to the electric telescopic rod 45, and the output ends of the two electric telescopic rods 45 are fixedly connected to the adjustment seat 23. The outer walls on both sides of the two adjustment seats 23 are provided with telescopic connecting rods 24, and the output ends of the four telescopic connecting rods 24 are fixedly connected to the connecting rods 22. The two ends of the four connecting rods 22 are movably connected to the inner walls on both sides of the four connecting ports, and the top of the partition plate 19 is fixedly connected to the guide baffle 17.

[0028] Specifically, when the electroplating sludge is precipitated, the sludge in the precipitation process will fall on the guide baffle 17, so that the sludge falls on the bottom of the treatment box 2 through the precipitation hole 16. After the electroplating sludge inside the treatment box 2 is completely precipitated, the electric telescopic rod 45 is started, so that the electric telescopic rod 45 drives the adjustment member to move downward. At this time, the adjustment member drives the telescopic link 24 when moving, so that the telescopic link 24 drives the blocking plate 20 to move, so that the blocking plate 20 rotates and drives the mounting seat 26 to move on the guide rod 25, so that the blocking plate 20 gradually approaches the top of the partition plate 19. When the blocking plate 20 contacts the partition plate 19, the telescopic link 24 is extended and retracted, so that the blocking plate 20 completely blocks the mounting port 18, thereby separating the electroplating sludge in the lower layer from the electroplating wastewater in the upper layer.

[0029] In a specific application scenario, separating the electroplating sludge from the electroplating wastewater by the partition plate 19 can avoid the electroplating sludge from mixing with the upper layer of electroplating wastewater when the sludge is cleaned and removed, thereby improving the chemical precipitation effect of the electroplating wastewater, and at the same time avoiding the electroplating sludge from affecting the subsequent treatment links of the electroplating wastewater, thereby improving the use effect of the device and increasing the treatment efficiency of the electroplating wastewater. When the electroplating sludge is precipitated, the sludge precipitation can be guided by the guide baffle 17, so that the sludge falls inside the installation port 18, and then precipitated through the precipitation hole 16, avoiding a large amount of sludge precipitation on the top of the partition plate 19, thereby improving the practicality of the device.

[0030] Reference Figure 1 and Figure 8 In a preferred embodiment, a reflux bin 5 is fixedly connected to the outer wall of one side of the treatment box 2, and a reflux port is provided on the outer wall of one side of the treatment box 2. The reflux port is connected to the interior of the reflux bin 5, and a water filter net 44 is fixedly connected to the inner wall of the reflux port; a reflux pump 42 is fixedly connected to the top of the reflux bin 5, and the output end of the reflux pump 42 is fixedly connected to two connecting pipes 43 through a pipeline, and the output ends of the two connecting pipes 43 are fixedly connected to the interior of the treatment box 2.

[0031] Specifically, before the electroplating sludge is removed, the second motor 33 drives the screw 31 to rotate, causing the screw 31 to drive the partition plate 19 downward, thereby squeezing the electroplating sludge below. At this time, the excess electroplating wastewater in the electroplating sludge below will flow into the reflux chamber 5 through the water filter 44 due to pressure. At this time, the reflux pump 42 is started to transport the excess electroplating wastewater to the upper layer of the partition plate 19 through the connecting pipe 43.

[0032] In a specific application scenario, the water filter plate can prevent electroplating sludge from entering the reflux bin 5 along with the electroplating wastewater to avoid mixing of sludge and wastewater, while the reflux pump 42 and the connecting pipe 43 can reflux excess electroplating wastewater to avoid part of the electroplating wastewater from being unable to undergo subsequent treatment, thereby improving the use effect of the device and the treatment effect of electroplating wastewater.

[0033] Reference Figure 1 、 Figure 2 and Figure 3In a preferred embodiment, fixed openings are provided on the outer walls of both sides of the processing box 2, and the inner walls of the two fixed openings are fixedly connected to mounting plates 6. The tops of the two mounting plates 6 are movably connected to the same filter box 3, and a plurality of filter holes 9 are equidistantly provided at the bottom of the filter box 3; two impact rods 7 are fixedly connected to the tops of the two mounting plates 6, and four movable holes 8 are provided on the top of the filter box 3. The inner walls of the four movable holes 8 are fixedly connected to rubber pads 10, and the four impact rods 7 are respectively located inside the four movable holes 8; a handle on one side of the processing box 2 is fixedly connected to the first motor 4, and the output shaft of the first motor 4 is connected to the driving gear 15 through a coupling, a gear plate 11 is fixedly connected to the outer wall of one side of the filter box 3, and the driving gear 15 is meshed with the gear plate 11, and two return spring rods 13 are fixedly connected to the inner wall of one side of the processing box 2, and one end of the two return spring rods 13 is fixedly connected to a connector 12, and two connecting holes 14 are provided on the outer wall of one side of the gear plate 11, and the outer walls of the two connectors 12 are in contact with the inner walls of the two connecting holes 14 respectively.

[0034] Specifically, before the wastewater treatment is carried out, the electroplating wastewater is injected into the treatment box 2. At this time, the electroplating wastewater will be preliminarily filtered through the filter box 3 to remove impurities in the electroplating wastewater. When in use, the driving gear 15 is driven to rotate by the first motor 4, and because the driving gear 15 is engaged with the gear plate 11, the driving gear 15 can drive the filter box 3 to move. When it moves to a specified position, the driving gear 15 is separated from the gear plate 11, and the filter box 3 is reset under the action of the reset spring rod 13, so that the filter box 3 shakes left and right, and while shaking, the inner wall of the movable hole 8 contacts the outer wall of the impact rod 7, thereby causing the filter box 3 to vibrate.

[0035] In a specific application scenario, preliminary filtration is performed through the filter box 3 to remove impurities in the electroplating wastewater, thereby facilitating subsequent treatment of the electroplating wastewater. During filtration, vibration can prevent the filter holes 9 on the filter box 3 from becoming clogged after long-term use, thereby reducing the number of times the staff cleans the filter box 3 and improving the use effect of the device. During impact, the rubber pad 10 can prevent the impact rod 7 from being damaged, thereby increasing the service life of the device. The filter box 3 can be quickly disassembled when use is completed, and the operation is convenient.

[0036] Reference Figure 1 and Figure 7In a preferred embodiment, four shock-absorbing support rods 38 are fixedly connected to the bottom of the processing box 2, and the outer walls of the four shock-absorbing support rods 38 are movably connected to the shock-absorbing sleeve rods 41. The bottoms of the four shock-absorbing sleeve rods 41 are fixedly connected to the same base 1, and the bottoms of the four shock-absorbing support rods 38 are fixedly connected to the limiting tooth plates 39; the outer walls of the four limiting tooth plates 39 are respectively in contact with the inner walls of the four shock-absorbing sleeve rods 41, and the bottoms of the inner walls of the four shock-absorbing sleeve rods 41 are fixedly connected with buffer spring rods 40, and the top ends of the four buffer spring rods 40 are respectively fixedly connected to the bottoms of the four limiting tooth plates 39.

[0037] Specifically, when the filter box 3 is filtering, vibration is generated, and the vibration is transmitted to the shock-absorbing support rod 38, so that the shock-absorbing support rod 38 drives the limiting tooth plate 39 to move on the inner wall of the shock-absorbing sleeve rod 41. At this time, the buffer spring rod 40 has a buffering and energy-absorbing effect, thereby reducing the vibration generated during filtration.

[0038] In a specific application scenario, the buffer spring rod 40 has the function of buffering and absorbing energy, which can reduce the vibration generated during filtering, and at the same time reduce the vibration between the device and the ground, thereby reducing the noise generated by the device and improving the use effect of the device.

[0039] Reference Figure 1 and Figure 6 In a preferred embodiment, two stirring rods 29 are fixedly connected to the outer wall of the screw rod 31, three stirring members 32 are fixedly connected to the outer walls of the two stirring rods 29 at equal distances, and a plurality of cleaning bristles 28 are provided on the outer walls of the six stirring members 32 at equal distances; two sewage outlets are provided at the bottom of the processing box 2, and the inner walls of the two sewage outlets are fixedly connected to sewage bins 34, and a plurality of sewage holes 27 are provided on the outer walls of the two sewage bins 34 at equal distances, and the bottoms of the two sewage bins 34 are fixedly connected to the same delivery pipe 35, and the output end of the delivery pipe 35 is fixedly connected to a delivery pump 36, and the output end of the delivery pump 36 is fixedly connected to a sewage pipe 37 through a pipeline.

[0040] Specifically, when cleaning and removing the electroplating sludge, the delivery pump 36 is started so that the delivery pump 36 can suck the electroplating sludge into the sewage bin 34 through the delivery pipe 35 and the sewage hole 27, and then the electroplating sludge is discharged through the sewage pipe 37 through the delivery pipe 35 and the delivery pump 36. At the same time, when discharging sewage, the screw rod 31 can drive the stirring rod 29 and the stirring member 32 to rotate, thereby breaking up the electroplating sludge. After the sludge removal and electroplating wastewater treatment are completed, the cleaning bristles 28 on the stirring member 32 can clean the lower layer of the treatment box 2;

[0041] In a specific application scenario, the cleaning bristles 28 facilitate the staff to clean the device after use, and when discharging sewage, the stirring rod 29 and the stirring member 32 can break up the electroplating sludge, avoiding the situation where only part of the electroplating sludge can be removed during sewage discharge, thereby improving the sewage discharge effect and efficiency of the device.

[0042] Working principle: When in use, before the wastewater treatment, the electroplating wastewater is injected into the treatment box 2, and the first motor 4 drives the driving gear 15 to rotate, and because the driving gear 15 is meshed with the gear plate 11, the driving gear 15 can drive the filter box 3 to move. When it moves to the specified position, the driving gear 15 will separate from the gear plate 11, and the filter box 3 will be reset under the action of the reset spring rod 13, so that the filter box 3 will shake left and right; when the filter box 3 is filtering, vibration will be generated, and at this time the vibration will be transmitted to the shock-absorbing support rod 38, so that the shock-absorbing support rod The rod 38 drives the limit tooth plate 39 to move on the inner wall of the shock-absorbing sleeve rod 41. At this time, since the buffer spring rod 40 has the function of buffering and absorbing energy, the vibration generated during filtration can be reduced. After the electroplating sludge inside the processing box 2 is completely precipitated, the electric telescopic rod 45 is started, so that the electric telescopic rod 45 drives the adjusting member to move downward. At this time, the adjusting member will drive the telescopic connecting rod 24 when moving, so that the telescopic connecting rod 24 drives the blocking plate 20 to move, so that the blocking plate 20 rotates and drives the mounting seat 26 to move on the guide rod 25, so that the blocking plate 20 gradually separates from the partition plate 19. The tops are close to each other, and when the blocking plate 20 contacts the partition plate 19, the telescopic connecting rod 24 is extended and retracted, so that the blocking plate 20 completely blocks the installation port 18, thereby separating the electroplating sludge in the lower layer from the electroplating wastewater in the upper layer; before the electroplating sludge is processed and removed, the second motor 33 drives the screw rod 31 to rotate, so that the screw rod 31 drives the partition plate 19 to descend, thereby squeezing the electroplating sludge below. At this time, the excess electroplating wastewater in the electroplating sludge below will enter the reflux bin 5 from the water filter net 44 due to pressure. At this time, the reflux pump 42 is started to remove the excess electroplating wastewater through the connecting rod 42. The pipe 43 is used to transport the electroplating sludge to the upper layer of the partition plate 19; when cleaning and removing the electroplating sludge, the delivery pump 36 is started so that the delivery pump 36 can suck the electroplating sludge into the sewage bin 34 through the delivery pipe 35 and the sewage hole 27, and then the electroplating sludge is discharged through the sewage pipe 37 through the delivery pipe 35 and the delivery pump 36. At the same time, when discharging sewage, the screw rod 31 can drive the stirring rod 29 and the stirring member 32 to rotate, thereby breaking up the electroplating sludge. After completing the sludge removal and the treatment of the electroplating wastewater, the cleaning brush 28 on the stirring member 32 can clean the lower layer of the treatment box 2.
