Description

Technical Field

[0001] The invention relates to the field of electroplating wastewater treatment, and in particular to a sedimentation tank for electroplating wastewater treatment and a sedimentation treatment method thereof. Background Art

[0002] Electroplating wastewater refers to wastewater generated in the electroplating process, which usually contains a variety of harmful substances, including heavy metal ions (such as chromium, nickel, copper, zinc, cobalt, silver, etc.), acidic or alkaline substances, surfactants, chemical additives, and other pollutants. In order to effectively remove these pollutants, a common method is to use a sedimentation tank in the electroplating wastewater treatment process to remove heavy metals and other pollutants dissolved in the water from the wastewater through physical and chemical methods.

[0003] Some existing sedimentation tanks treat electroplating wastewater by discharging the wastewater into the sedimentation tank, pouring treatment agents into the sedimentation tank, fusing the agents with pollutants in the wastewater, and using heavy metal ions to react with the agents to generate water-insoluble precipitates, which are then separated and removed by precipitation. However, when the agents and wastewater pollutants are fused, the agents are not in sufficient contact with the pollutants in the water, resulting in a poor reaction effect. In addition, some electroplating wastewater contains hydrogen sulfide, which reacts with the agents to generate hydrogen sulfide gas. Hydrogen sulfide is toxic and has the smell of rotten eggs. Direct discharge affects the environment. After the wastewater treatment is completed, the sedimentation tank needs to be cleaned, but the sludge at the bottom of the sedimentation tank is inconvenient to clean. Summary of the invention

[0014] A sedimentation treatment method for a sedimentation tank for electroplating wastewater treatment comprises the following steps: S1. When treating electroplating wastewater, sodium hydroxide solid material is added into the cylinder by rotating the screw cap, and then the screw cap is rotated to cover the cylinder, and the electroplating wastewater is discharged into the tank body through multiple water inlet pipes. At this time, the output end of the hydraulic rod is controlled to drive the connection box to move downward, so that the two second stirring blades and the first stirring blade are inserted into the wastewater, and there is a distance between the two second stirring blades and the first stirring blade. The two second stirring blades are at the bottom layer of the wastewater, and the first stirring blade is at the upper layer of the wastewater; S2. At this time, the treatment agent is poured into the inside of the pool body, and then the external power switch of the driving motor is turned on, which further drives the rotating rod to rotate, so that the first stirring blade rotates, and the two second gears rotate under the drive of the first gear, and the two second stirring blades rotate through the two transmission rods. The first stirring blade stirs the wastewater close to the upper layer, and the two second stirring blades stir the wastewater in the lower layer.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are: 1. When treating electroplating wastewater, the present invention discharges the electroplating wastewater into the interior of the tank body through multiple water inlet pipes. At this time, the output end of the hydraulic rod is controlled to drive the connection box to move downward, so that the two second stirring blades and the first stirring blade are inserted into the interior of the wastewater. There is a distance between the two second stirring blades and the first stirring blade. The two second stirring blades are at the bottom layer of the wastewater, and the first stirring blade is at the upper layer of the wastewater. At this time, the treatment agent is poured into the interior of the tank body. At this time, the external power switch of the driving motor is turned on, which further drives the rotating rod to rotate, so that the first stirring blade rotates, and the two second gears rotate under the drive of the first gear. The two second stirring blades rotate through two transmission rods, and the first The stirring blade stirs the wastewater close to the upper layer, and the two second stirring blades stir the wastewater in the lower layer, so that the suspended matter on the water surface and the sediment in the deeper water area can fully merge and react with the reagent.

The wastewater after the pool body treatment is discharged into the multiple second diversion pipes through the multiple first diversion pipes under the action of the multiple delivery pumps, and further discharged into the purification tank for purification treatment. Therefore, when the sedimentation tank treats the electroplating wastewater, the reagent is fully in contact with the pollutants in the water, and both the suspended matter on the water surface and the sediment in the deeper water area can be evenly distributed and reacted, thereby improving the efficiency of the reagent use and the reaction effect.

[0016] 2. When the present invention treats waste water, sodium hydroxide solid matter is added to the inside of the cylinder by rotating the screw cover, and then the screw cover is rotated to cover the cylinder. The hollow cylinder is above the water surface. When the rotating rod drives the first stirring blade to rotate clockwise, it will drive the first pulley to rotate clockwise, and further drive the second pulley to rotate through the belt, so that the round rod rotates clockwise. When the round rod rotates clockwise, it drives multiple stirring plates and fan blades to rotate together. When the fan blades rotate clockwise, they push air from the front to the back, inhale the gas generated by the waste water treatment, and further discharge it to the inside of the cylinder through the exhaust hole on the hollow cylinder. At this time, the multiple stirring plates stir the sodium hydroxide solid matter inside the cylinder, so that the sodium hydroxide and hydrogen sulfide in the gas are fully fused and reacted, hydrogen sulfide is absorbed, and the emission of hydrogen sulfide gas is reduced. Therefore, when the waste water is treated, the hydrogen sulfide in the gas is treated, and the practicality of the sedimentation tank is improved.

[0017] 3. After the wastewater treatment is completed, the connecting rod of the present invention can slide on the inner wall of the groove, and the sleeve and the connecting rod are connected together. Then, when the threaded rod rotates in different directions, the sleeve moves to different directions on the outer surface of the threaded rod. At this time, the external power switch of the bidirectional motor is turned on, and the output shaft of the bidirectional motor can rotate forward and reverse, further driving the threaded rod to rotate in different directions. One side of the scraper is tightly attached to the bottom of the pool body. When the sleeve moves, the scraper is driven to move by the connecting rod. The scraper scrapes the inner wall of the pool body and the sludge at the bottom of the pool body. At this time, the sewage inside the pool body is discharged through multiple sewage pipes, so that when the sedimentation tank is in use, the sedimentation tank is easy to clean.

[0040] Working principle: When treating electroplating wastewater, the electroplating wastewater is discharged into the interior of the tank body 1 through multiple water inlet pipes 214. At this time, the connecting box 203 is driven downward by controlling the output end of the hydraulic rod 202. The fixed ring 201 supports the hydraulic rod 202, so that the hydraulic rod 202 is installed on the top of the bracket 2, so that the two second stirring blades 210 and the first stirring blade 206 are inserted into the interior of the wastewater. There is a distance between the two second stirring blades 210 and the first stirring blade 206. The two second stirring blades 210 are at the bottom layer of the wastewater, and the first stirring blade 206 is at the upper layer of the wastewater. At this time, the treatment agent is poured into the interior of the tank body 1, and the external power switch of the driving motor 204 is turned on, which further drives the rotating rod 205 to rotate, so that the first stirring blade 206 rotates, and the two second gears 209 are on the first gear 207. The first stirring blade 206 stirs the wastewater near the upper layer, and the two second stirring blades 210 stir the wastewater at the lower layer, so that the suspended matter on the water surface and the sediment in the deeper water area are fully fused and reacted with the reagent. After the wastewater inside the pool body 1 is treated, the external power switches of the multiple delivery pumps 215 are turned on. The wastewater treated by the pool body 1 is discharged into the multiple second flow guide pipes 212 through the multiple first flow guide pipes 211 under the action of the multiple delivery pumps 215, and further discharged into the purification pool 213 for purification treatment. Therefore, when the sedimentation tank treats the electroplating wastewater, the reagent is fully in contact with the pollutants in the water, and both the suspended matter on the water surface and the sediment in the deeper water area can be evenly distributed and reacted, thereby improving the efficiency of the reagent use and the reaction effect.

When the rotating rod 205 drives the first stirring blade 206 to rotate clockwise, the first pulley 302 is driven to rotate clockwise, and the second pulley 304 is further driven to rotate through the belt 303, so that the round rod 301 rotates clockwise. When the round rod 301 rotates clockwise, the plurality of stirring plates 307 and The fan blades 306 rotate together. When the fan blades 306 rotate clockwise, they push the air from the front to the back, sucking in the gas generated by the wastewater treatment, and further discharging it into the inside of the cylinder 305 through the exhaust holes on the hollow cylinder 3. At this time, the multiple stirring plates 307 stir the sodium hydroxide solid material inside the cylinder 305, so that the sodium hydroxide and the hydrogen sulfide in the gas fully fuse and react, absorb the hydrogen sulfide, and reduce the emission of hydrogen sulfide gas, so that when the wastewater is treated, the hydrogen sulfide in the gas is treated, and the practicality of the sedimentation tank is improved; After the wastewater treatment is completed, the connecting rod 403 can slide on the inner wall of the groove 407, and the sleeve 402 and the connecting rod 403 are connected together. Then, when the threaded rod 401 rotates in different directions, the sleeve 402 moves to different directions on the outer surface of the threaded rod 401. At this time, the external power switch of the bidirectional motor 405 is turned on, and the output shaft of the bidirectional motor 405 can rotate forward and reverse, further driving the threaded rod 401 to rotate in different directions. One side of the scraper 404 is tightly attached to the bottom of the pool body 1. When the sleeve 402 moves, the scraper 404 is driven to move by the connecting rod 403. The scraper 404 scrapes the inner wall of the pool body 1 and the sludge at the bottom of the pool body 1. At this time, the sewage inside the pool body 1 is discharged through multiple sewage pipes 406, so that when the sedimentation tank is in use, the sedimentation tank is easy to clean.

A sedimentation treatment method for a sedimentation tank for electroplating wastewater treatment, characterized in that: A sedimentation tank for treating electroplating wastewater according to any one of claims 1 to 9, comprising the following steps: S1. When treating electroplating wastewater, sodium hydroxide solid is added into the cylinder (305) by rotating the screw cap (308), and then the screw cap (308) is rotated to cover the cylinder (305), and the electroplating wastewater is discharged into the interior of the tank body (1) through a plurality of water inlet pipes (214). At this time, the output end of the hydraulic rod (202) is controlled to drive the connection box (203) to move downward, so that the two second stirring blades (210) and the first stirring blade (206) are inserted into the interior of the wastewater, and there is a distance between the two second stirring blades (210) and the first stirring blade (206), so that the two second stirring blades (210) are located at the bottom layer of the wastewater, and the first stirring blade (206) is located at the upper layer of the wastewater; S2, at this time, the treatment agent is poured into the interior of the pool body (1), and then the external power switch of the driving motor (204) is turned on, which further drives the rotating rod (205) to rotate, so that the first stirring blade (206) rotates, and the two second gears (209) rotate under the drive of the first gear (207), and the two second stirring blades (210) rotate through the two transmission rods (208). The first stirring blade (206) stirs the wastewater near the upper layer, and the two second stirring blades (210) stir the wastewater at the lower layer. The suspended matter on the water surface and the sediment in the deeper water area react with the agent. The hollow cylinder (3) is above the water surface. When the rotating rod (205) drives the first stirring blade (206) to rotate clockwise, it drives the first pulley (302) to rotate clockwise, and further drives the second pulley (304) to rotate through the belt (303), so that the round rod (301) rotates clockwise; S3, when the round rod (301) rotates clockwise, the plurality of stirring plates (307) and the fan blades (306) are driven to rotate together. When the fan blades (306) rotate clockwise, the air is pushed from the front to the rear, and the gas generated by the wastewater treatment is sucked in, and further discharged into the inside of the cylinder (305) through the exhaust hole on the upper side of the hollow cylinder (3). At this time, the plurality of stirring plates (307) stir the sodium hydroxide solid material inside the cylinder (305), so that the sodium hydroxide and the hydrogen sulfide in the gas are fully fused and reacted, and the hydrogen sulfide is absorbed; S4, after the wastewater inside the tank body (1) is treated, the external power switches of the multiple delivery pumps (215) are turned on, and the wastewater after the treatment in the tank body (1) is discharged into the multiple second flow guide pipes (212) through the multiple first flow guide pipes (211) under the action of the multiple delivery pumps (215), and further discharged into the purification tank (213) for purification treatment; S5. After the wastewater treatment is completed, the external power switch of the bidirectional motor (405) is turned on, and the output shaft of the bidirectional motor (405) can rotate forward and reverse, further driving the threaded rod (401) to rotate in different directions. One side of the scraper (404) is closely attached to the bottom of the pool body (1). When the sleeve (402) moves, the scraper (404) is driven to move through the connecting rod (403). The scraper (404) scrapes the inner wall of the pool body (1) and the sludge at the bottom of the pool body (1). At this time, the sewage inside the pool body (1) is discharged through multiple sewage pipes (406).
