Description

Technical Field

[0001] The present invention belongs to the technical field of chromium-contaminated water body restoration, and in particular relates to a chromium-contaminated water body restoration device and a chromium-contaminated water body restoration method. Background Art

[0002] Chromium metal is widely used in industrial fields such as metal electroplating, paints and pigments, leather making, textile dyeing, wood preservation and refractory materials. There are many chromium-related industries and chromium pollution is a universal problem. Due to the non-degradability of heavy metals themselves, improper discharge of chromium-containing waste residues and wastewater will cause serious environmental pollution problems. Therefore, before discharging chromium-contaminated water bodies, the chromium-contaminated water bodies need to be repaired.

[0003] When repairing chromium-contaminated water bodies, the existing technology usually discharges the chromium-contaminated water bodies onto the granular activated carbon plates, and uses the granular activated carbon plates to adsorb chromium and other impurities in the chromium-contaminated water bodies, thereby repairing the chromium-contaminated water bodies. However, when using the activated carbon plates to repair the chromium-contaminated water bodies, since the chromium-contaminated water bodies are prone to contain large impurities or agglomerated particles, when the chromium-contaminated water bodies are directly discharged to the surface of the activated carbon plates for repair, the large impurities or agglomerated particles contained in the chromium-contaminated water bodies will remain on the surface of the activated carbon plates, causing clogging of the activated carbon plates, thereby reducing the removal efficiency of the activated carbon for chromium and other impurities. Moreover, after the granular activated carbon plates have adsorbed a certain amount of chromium and other impurities, they need to be manually replaced with new activated carbon plates. However, during the replacement process, the discharge of the chromium-contaminated water bodies needs to be stopped first. After the staff replaces the new activated carbon plates, the chromium-contaminated water bodies are discharged again. The steps are complicated, which greatly reduces the efficiency of repairing the chromium-contaminated water bodies.

[0004] To this end, we propose a device and method for repairing chromium-contaminated water to solve the above problems. Summary of the Invention

[0014] A method for repairing chromium-contaminated water bodies comprises the following steps:

[0015] S1: When chromium-contaminated water needs to be repaired, the water pump is controlled to start and sodium thiosulfate is transported to the rotating tube. At the same time, the motor is controlled to start and drive the rotating tube and the stirring tube to rotate. During the rotation process, the sodium thiosulfate flows into multiple stirring tubes through the rotating tube and finally is discharged into the chromium-contaminated water through the liquid outlet. The stirring of the stirring tube allows the chromium-contaminated water to be evenly mixed with the sodium thiosulfate, so that the hexavalent chromium in the chromium-contaminated water is reduced to trivalent chromium. At this time, the trivalent chromium is not easily soluble in water and can form a precipitate, which is convenient for removal;

[0016] S2: Then, one of the solenoid valves is controlled to open, so that the chromium-contaminated water in the conversion cylinder is transported to the repair box through the corresponding connecting pipe. The chromium-contaminated water will first be discharged above the filter plate, where the filter plate will filter out large impurities in the chromium-contaminated water. The filtered chromium-contaminated water will be discharged above the activated carbon plate, where the granular activated carbon plate will adsorb trivalent chromium and other impurities in the chromium-contaminated water. Finally, the water will be discharged through the drain pipe, completing the repair of the chromium-contaminated water.

[0017] S3: When the filter plate is filtering large impurities in the chromium-contaminated water, it is detected whether the filter plate is blocked. After the filter plate is detected to be blocked, the impurities blocked in the filter hole can be extracted, and the impurities can be pushed into the collection box using the push plate to prevent the filter plate from being blocked and affecting the filtering efficiency of the chromium-contaminated water. At the same time, when it is detected that the activated carbon plate needs to be replaced, the chromium-contaminated water can be discharged into another repair box to repair the chromium-contaminated water. The activated carbon plate can also be replaced automatically to avoid the need to stop the discharge of the chromium-contaminated water when manually replacing the activated carbon plate, thereby greatly increasing the repair efficiency of the chromium-contaminated water.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The adsorption component and the filtering component set up can use the filter plate to filter out large impurities in the chromium-contaminated water during the repair process of the chromium-contaminated water body, thereby preventing large impurities from staying on the surface of the activated carbon plate, causing the surface of the activated carbon plate to be blocked, and reducing the removal efficiency of the activated carbon for chromium and other impurities. It can also detect whether the filter plate is blocked. After detecting that the filter plate is blocked, the impurities blocked in the filter hole can be extracted, and the push plate can be used to push the impurities into the collection box to prevent the filter plate from being blocked and affecting the filtering efficiency of the chromium-contaminated water body. At the same time, when it is detected that the activated carbon plate needs to be replaced, the chromium-contaminated water body can be discharged into another repair box to repair the chromium-contaminated water body. The activated carbon plate can also be automatically replaced to avoid the need to stop the discharge of the chromium-contaminated water body when manually replacing the activated carbon plate, thereby greatly increasing the repair efficiency of the chromium-contaminated water body.

[0043] A method for repairing chromium-contaminated water bodies comprises the following steps:

[0044] S1: When it is necessary to repair the chromium-contaminated water body, the water pump 4 is controlled to start and sodium thiosulfate is transported into the rotating tube 3. At the same time, the motor 5 is controlled to start and drive the rotating tube 3 and the stirring tube 7 to rotate. During the rotation process, the sodium thiosulfate will flow into the multiple stirring tubes 7 through the rotating tube 3 and finally be discharged into the chromium-contaminated water body through the liquid outlet 8. The stirring of the stirring tube 7 allows the chromium-contaminated water body to be evenly mixed with the sodium thiosulfate, so that the hexavalent chromium in the chromium-contaminated water body is reduced to trivalent chromium. At this time, the trivalent chromium is not easily soluble in water and can form a precipitate, which is convenient for removal;

[0045] S2: Then, one of the solenoid valves 12 is controlled to open, so that the chromium-contaminated water in the conversion cylinder 1 is transported to the repair box 10 through the corresponding connecting pipe 11. The chromium-contaminated water is first discharged above the filter plate 131, where the filter plate 131 filters out large impurities in the chromium-contaminated water. The filtered chromium-contaminated water is then discharged above the activated carbon plate, where the granular activated carbon plate adsorbs trivalent chromium and other impurities in the chromium-contaminated water. Finally, the water is discharged through the drain pipe 15, completing the repair of the chromium-contaminated water.

[0046] S3: When the filter plate 131 is filtering large impurities in the chromium-contaminated water body, whether the filter plate 131 is blocked is detected. After detecting that the filter plate 131 is blocked, the impurities blocked in the filter hole can be extracted, and the push plate 1315 is used to push the impurities into the collection box 1316 to prevent the filter plate 131 from being blocked and affecting the filtering efficiency of the chromium-contaminated water body. At the same time, when it is detected that the activated carbon plate needs to be replaced, the chromium-contaminated water body can be discharged into another repair box 10 to repair the chromium-contaminated water body. The activated carbon plate can also be replaced automatically to avoid the need to stop the discharge of the chromium-contaminated water body when manually replacing the activated carbon plate, thereby greatly increasing the repair efficiency of the chromium-contaminated water body.

[0047] The operating principle of the present invention is now described as follows:

[0048] In the present invention, when it is necessary to repair the chromium-contaminated water body, first control the fifth electric telescopic rod 1412 to start, drive the first card plate 1413 to move a distance, and then the staff will place the granular activated carbon plate on the two support plates 144, use the two support plates 144 to support the activated carbon plate, and then put multiple granular activated carbon plates into the placement box 141, use the two first card plates 1413 to support the granular activated carbon, and multiple activated carbon plates are stacked and arranged, and then the external water pipe is connected to the inlet end of the water pump 4, and then the chromium-contaminated water body is discharged into the conversion cylinder 1 through the liquid inlet pipe 6, and then the external water pipe is passed into sodium thiosulfate, and the water pump 4 is controlled to start to transport the sodium thiosulfate into the rotating tube 3, and at the same time, the motor 5 is controlled to start to drive The rotating tube 3 and the stirring tube 7 rotate. During the rotation process, sodium thiosulfate will flow into the multiple stirring tubes 7 through the rotating tube 3, and finally be discharged into the chromium-contaminated water through the liquid outlet 8. The chromium-contaminated water can be evenly mixed with the sodium thiosulfate through the stirring of the stirring tube 7, so that the hexavalent chromium in the chromium-contaminated water is reduced to trivalent chromium. At this time, the trivalent chromium is not easily soluble in water and can form a precipitate, which is convenient for removal. Then, one of the solenoid valves 12 is controlled to open, so that the chromium-contaminated water in the conversion cylinder 1 is transported to the repair box 10 through the corresponding connecting pipe 11. The chromium-contaminated water will first be discharged to the top of the filter plate 131, and the filter plate 131 will be used to filter the large impurities in the chromium-contaminated water. The filtered chromium-contaminated water will be discharged to the activated carbon Above the plate, the granular activated carbon plate is used to adsorb trivalent chromium and other impurities in the chromium-contaminated water body, and finally discharged through the drain pipe 15 to complete the repair of the chromium-contaminated water body. In the process of repairing the chromium-contaminated water body, the third electric slide rail 1323 is controlled to start, driving the third slide plate 1324 to move back and forth in the repair box 10, and at the same time driving the detection plate 1325 to move. Since the detection plate 1325 is below the filter plate 131, the filtered chromium-contaminated water body will continuously contact the pressure plate 1327, applying pressure to the pressure plate 1327. At this time, the pressure value detected by the pressure sensor 1326 is large. When the filter hole of the filter plate 131 is blocked, the pressure plate 1327 passes the blocked position of the filter plate 131. At this time, the filter plate 131 The amount of chromium-contaminated water discharged downward is small, and the pressure on the pressure plate 1327 is small. At this time, the pressure detected by the pressure sensor 1326 is small, indicating that the filter plate 131 here is blocked. Then the first electric slide rail 133 is controlled to start, so that the first slide plate 134 drives the connecting plate 135 to move, so that the vacuum suction cup 139 moves to the position corresponding to the pressure plate 1327. Then the first electric telescopic rod 137 is controlled to start, so that the vacuum suction cup 139 contacts the upper surface of the filter plate 131. Then the air pump 1310 is controlled to start, and the air in the space formed by the connecting shell 138, the vacuum suction cup 139 and the upper surface of the filter plate 131 is extracted, thereby sucking out the impurities blocked in the filter hole. Then the first electric telescopic rod 137 is controlled to return to its original position.Then the second electric telescopic rod 1312 is controlled to start, so that the push plate 1315 contacts the upper surface of the filter plate 131, and then the first electric slide rail 133 is controlled to drive the first slide plate 134 to move toward the inner wall of one end of the repair box 10. During the process again, the push plate 1315 will push the impurities on the surface of the filter plate 131 to the baffle 1319. After the first slide plate 134 moves to the baffle 1319, the third electric telescopic rod 1314 is controlled to start, driving the push plate 1315 to move toward the baffle 1319, and the impurities filtered on the surface of the filter plate 131 are pushed into the collection box 1316, so that the filter plate 131 can quickly filter the large impurities in the chromium-contaminated water body. In the process of repairing the chromium-contaminated water body with the granular activated carbon plate, as the activated carbon plate filters the impurities Trivalent chromium and other impurities are continuously adsorbed in the chromium-contaminated water, and the mass of the activated carbon plate will continue to increase. When the trivalent chromium and other impurities adsorbed by the activated carbon plate reach saturation, the mass of the activated carbon plate will continue to increase, and it will overcome the elastic force of the support spring 143 and drive the support plate 144 to move downward. When the first conductive plate 145 contacts the second conductive plate 147, it means that the activated carbon plate cannot adsorb trivalent chromium and other impurities, and the activated carbon plate needs to be replaced. At this time, the corresponding solenoid valve 12 is closed, and another solenoid valve 12 is controlled to open. Another repair box 10 is used to repair the chromium-contaminated water body, and then the second electric slide rail 1418 is controlled to start, driving the second slide plate 1419 to move, so that the U-shaped plate 1421 moves to the repair box. 10, and then control the seventh electric telescopic rod 1420 to start, so that the U-shaped plate 1421 moves toward the activated carbon plate. When the two blocking blocks 1423 are respectively located above and below the activated carbon plate, the eighth electric telescopic rod 1422 is controlled to start, driving the blocking block 1423 to move and fix the activated carbon plate. Then, the seventh electric telescopic rod 1420 is controlled to contract, and the activated carbon plate is completely pulled out of the repair box 10. Then, the eighth electric telescopic rod 1422 is controlled to return to its original position, and the seventh electric telescopic rod 1420 is controlled to return to its original position. At this time, the activated carbon plate that cannot be used will fall to the bottom of the placement box 141. Then, the fourth electric telescopic rod 149 is controlled to start, and the splint 1410 is used to fix the activated carbon plate stacked on the first card plate 14 13 above is clamped, and the activated carbon plate clamped by the splint 1410 is the second one from bottom to top. Then the sixth electric telescopic rod 1415 is controlled to start, driving the second card plate 1416 to move a distance, and then the fifth electric telescopic rod 1412 is controlled to drive the first card plate 1413 to shrink, and no longer support the activated carbon plate above. At this time, the lowest activated carbon plate will fall above the second card plate 1416, and then the fifth electric telescopic rod 1412 is controlled to start, so that the first card plate 1413 moves a distance, and then the fourth electric telescopic rod 149 is controlled to drive the splint 1410 to return to its original position, and no longer clamp the activated carbon plate. At this time, the activated carbon plate will fall above the first card plate 1413, which is convenient for subsequent replacement of the activated carbon plate.Then, the second electric slide rail 1418 is controlled to start, so that the U-shaped plate 1421 moves to the position corresponding to the activated carbon plate placed above the second clamping plate 1416, and then the seventh electric telescopic rod 1420 is controlled to start, so that the U-shaped plate 1421 moves to a position where the activated carbon plate can be clamped by the clamping block 1423, and then the eighth electric telescopic rod 1422 is controlled to start, and the activated carbon plate is fixed by the clamping block 1423, and then the seventh electric telescopic rod 1420 is controlled to start again to move the activated carbon plate to the top of the support plate 144, completing the replacement of the activated carbon plate. When the activated carbon plate in another repair box 10 needs to be replaced, the chromium-contaminated water body is discharged into the replaced repair box 10, and then the activated carbon plate in the other repair box 10 is replaced according to the above steps. In the process of repairing the chromium-contaminated water body, the activated carbon plate can be used. The filter plate 131 filters large impurities in the chromium-contaminated water, preventing them from staying on the surface of the activated carbon plate and causing clogging of the activated carbon plate, thereby reducing the activated carbon's efficiency in removing chromium and other impurities. The filter plate 131 can also be used to detect whether it is clogged. Once the filter plate 131 is detected to be clogged, the impurities clogged in the filter holes can be extracted and pushed into the collection box 1316 using the push plate 1315, thereby preventing the clogging of the filter plate 131 from affecting the filtration efficiency of the chromium-contaminated water. At the same time, when it is detected that the activated carbon plate needs to be replaced, the chromium-contaminated water can be discharged into another repair box 10 for repair. The activated carbon plate can also be automatically replaced, avoiding the need to stop the discharge of the chromium-contaminated water when manually replacing the activated carbon plate, thereby greatly increasing the efficiency of repairing the chromium-contaminated water.
