Technical Field

[0001] This utility model relates to the technical field of electroplating wastewater, and in particular to a heavy metal ion adsorption treatment device for electroplating wastewater. Background Technology

[0002] Electroplating wastewater is a toxic wastewater generated during the production process of electroplating plants. It contains heavy metals (such as chromium, nickel, and copper), acids, alkalis, cyanides, and other harmful substances. Therefore, when treating electroplating wastewater, adsorption devices are often used to adsorb heavy metal ions and perform other related treatments to avoid pollution of water sources due to heavy metals contained in the water due to direct discharge.

[0003] When treating electroplating wastewater by adsorption, workers put the wastewater into the adsorption treatment device through pipes, and then add adsorbent to the device to adsorb the heavy metal ions. However, manual addition can easily cause differences in the amount added between different batches, which affects the treatment effect of electroplating wastewater. Therefore, experienced workers are generally required to control the process. However, even with manual control, it is still impossible to guarantee that the adsorbent is added evenly.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] The following describes an embodiment of the present invention, a heavy metal ion adsorption treatment device for electroplating wastewater, with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown in the figure, an electroplating wastewater heavy metal ion adsorption treatment device according to an embodiment of the present invention includes: a tank body 1, an adsorption treatment component 2, and a dosing component 3.

[0026] The adsorption treatment component 2 is installed inside the tank body 1, and the dosing components 3 are respectively installed on the outer wall of the tank body 1.

[0027] The dosing assembly 3 includes a dosing tank 31, a scale line 35, a metering pump 36, a connecting pipe 37, and a discharging pipe 38.

[0028] The dosing tank 31 is installed on the pool body 1, the scale line 35 is installed on the dosing tank 31, the metering pump 36 is installed on the dosing tank 31, the two ends of the connecting pipe 37 are connected to the input end of the metering pump 36 and the dosing tank 31 respectively, the discharge pipe 38 is connected to the output end of the metering pump 36, the dosing tank 31 is provided with a dosing port 32, the outer wall of the dosing tank 31 is provided with a water inlet 33, and the bottom of the dosing tank 31 is provided with a dosing outlet 34.

[0029] Specifically, when it is necessary to add chemicals to the tank 1, the staff first opens the dosing port 32 on the dosing tank 31 and adds an appropriate amount of fixed chemicals to the dosing tank 31. Then, they open the water inlet 33 and inject an appropriate amount of water into the dosing tank 31 according to the set ratio. They observe and control the amount of water added through the scale line 35. After the solid chemicals are fully mixed with the water, the metering pump 36 is started through the external starting device to transport the adsorbent prepared in the dosing tank 31 to the tank 1 to adsorb heavy metal ions.

[0030] In one embodiment of this application, such as Figure 1 As shown, the adsorption treatment component 2 includes an acid-base adjustment tank 21, an adsorption tank 22, and a sedimentation tank 23.

[0031] The acid-base adjustment tank 21 is located inside the tank body 1. The adsorption tank 22 is connected to the acid-base adjustment tank 21 and is located inside the tank body 1. The sedimentation tank 23 is connected to the adsorption tank 22 and is located inside the tank body 1.

[0032] Specifically, in the adsorption treatment of electroplating wastewater, the staff first put the wastewater into the acid-base adjustment tank 21 to adjust the acid-base value of the wastewater. Then, the internal pipes discharge the wastewater from the acid-base adjustment tank 21 into the adsorption tank 22 to adsorb heavy metal ions. Then, it is discharged into the sedimentation tank 23 for sedimentation, so that impurities settle to the bottom of the sedimentation tank 23.

[0033] In one embodiment of this application, such as Figure 1 and Figures 3-5 As shown, a footboard 4 is installed on the outer wall of the pool body 1, and a guardrail 5 is installed on the footboard 4. A drain pipe 6 and an inlet pipe 9 are respectively connected through the outer wall of the pool body 1. A filter assembly 7 is installed inside the drain pipe 6.

[0034] The filter assembly 7 includes a filter screen 73, a filter plate 75, a slider 76, filter holes 77, and a limiting tube 78.

[0035] The filter screen 73 is installed inside the pool body 1, and the inner wall of the discharge pipe 6 is provided with a groove 74.

[0036] The filter plates 75 are respectively installed in the discharge pipe 6, the sliders 76 are respectively installed in the corresponding slide grooves 74, and the sliders 76 are respectively connected to the filter plates 75. The outer wall of the filter plates 75 is respectively provided with filter holes 77. The limiting pipe 78 is threadedly connected to the discharge pipe 6. The inner walls on both sides of the pool body 1 are respectively provided with limiting blocks 71. The outer wall of the limiting block 71 is provided with limiting grooves 72. The filter screen 73 is provided with handles 8.

[0037] It should be noted that the pedal 4 described in this embodiment can provide a force-bearing position for the staff, allowing the staff to stand on the pedal 4 to observe the treatment effect and progress of the electroplating wastewater in the pool 1. The guardrail 5 can prevent the staff from accidentally falling off the pedal 4.

[0038] Specifically, when the electroplating wastewater has fully reacted in the sedimentation tank 23, after the limiting pipe 78 is connected to the external collection device, the discharge valve of the equipment is opened, and the wastewater is discharged from the discharge pipe 6. The filter screen 73 installed in the sedimentation tank 23 will first intercept large particles of sediment, and then the wastewater that has passed through the filter screen 73 will enter the discharge pipe 6 and come into contact with two filter plates 75 in sequence. The impurities in the water will be filtered again by the filter holes 77 on the filter plates 75, reducing the sediment in the treated discharge water.

[0039] When the discharge speed slows down, the staff can slide the filter screen 73 along the limiting groove 72 by lifting the handle 8 upwards to remove the filter screen 73 for cleaning. Then, after turning the limiting tube 78 to separate the limiting tube 78 from the discharge pipe 6, the filter plate 75 is moved along the slide groove 74 to remove the filter plate 75 for cleaning. Finally, the cleaned filter screen 73 and filter plate 75 can be reinstalled.

[0040] Working principle: When it is necessary to add chemicals to tank 1, the operator first opens the dosing port 32 on the dosing tank 31 and adds an appropriate amount of fixed chemical to the dosing tank 31. Then, the operator opens the water inlet 33 and injects an appropriate amount of water into the dosing tank 31 according to the set ratio. The operator observes and controls the amount of water added through the scale line 35. After the solid chemical and water are fully mixed, the metering pump 36 is started through the external starting device to transport the adsorbent prepared in the dosing tank 31 to tank 1 to adsorb heavy metal ions.

[0041] When treating electroplating wastewater by adsorption, the staff first put the wastewater into the acid-base adjustment tank 21 to adjust the acid-base value of the wastewater. Then, the internal pipes discharge the wastewater from the acid-base adjustment tank 21 into the adsorption tank 22 to adsorb heavy metal ions. Then, it is discharged into the sedimentation tank 23 for sedimentation, so that the impurities settle to the bottom of the sedimentation tank 23.

[0042] When the electroplating wastewater has fully reacted in the sedimentation tank 23, after connecting the limiting pipe 78 to the external collection device, the discharge valve of the equipment is opened, and the wastewater is discharged from the discharge pipe 6. The filter screen 73 installed in the sedimentation tank 23 will first intercept large particles of sediment, and then the wastewater that has passed through the filter screen 73 will enter the discharge pipe 6 and come into contact with two filter plates 75 in sequence. The impurities in the water will be filtered again by the filter holes 77 on the filter plates 75, reducing the sediment in the treated discharge water.

[0043] When the discharge speed slows down, the staff can slide the filter screen 73 along the limiting groove 72 by lifting the handle 8 upwards to remove the filter screen 73 for cleaning. Then, after turning the limiting tube 78 to separate the limiting tube 78 from the discharge pipe 6, the filter plate 75 is moved along the slide groove 74 to remove the filter plate 75 for cleaning. Finally, the cleaned filter screen 73 and filter plate 75 can be reinstalled.

[0044] In summary, by setting up an adsorbent storage tank on the adsorption treatment device, when it is necessary to add adsorbent to the device, the staff can start the metering pump 36 set on the storage tank to extract the adsorbent and deliver it into the adsorption treatment device, so as to achieve quantitative and uniform addition of adsorbent and ensure the adsorption effect on heavy metal ions in electroplating wastewater.
