Description

Technical Field

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

[0002] Electroplating wastewater refers to the wastewater generated in the electroplating process, which usually contains various 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, the commonly used method is to use a sedimentation tank in the electroplating wastewater treatment process, and remove the heavy metals and other pollutants dissolved in the water from the wastewater through physical and chemical methods.

[0003] When some existing sedimentation tanks treat electroplating wastewater, the wastewater is discharged into the interior of the sedimentation tank, and treatment agents are poured into the sedimentation tank. By fusing the agents with the pollutants in the wastewater, the heavy metal ions react with the agents to form precipitates insoluble in water, and then these substances are removed by sedimentation separation. However, when the agents are fused with the wastewater pollutants, the agents do not fully contact the pollutants in the water, resulting in a not very good reaction effect. Moreover, some electroplating wastewaters contain hydrogen sulfide. The hydrogen sulfide reacts with the agents to generate hydrogen sulfide gas. Hydrogen sulfide is a toxic gas with a rotten egg smell, and direct emission 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 not convenient to clean. Summary of the Invention

When the sedimentation tank of the present invention treats electroplating wastewater, the agents are in full contact with the pollutants in the water. Whether it is the suspended matter on the water surface or the sediment in the deeper water area, they can be evenly distributed and reacted, improving the use efficiency of the agents and the reaction effect. When treating the wastewater, the hydrogen sulfide in the gas is treated, improving the practicability of the sedimentation tank.

[0020] A sedimentation treatment method for a sedimentation tank used in electroplating wastewater treatment, comprising the following steps:

[0021] S1. When treating electroplating wastewater, sodium hydroxide solid substance is added into the inside of the cylinder by rotating the rotary cover, and then the rotary cover is rotated to cover the cylinder. The electroplating wastewater is discharged into the inside of the pool body through a plurality of water inlet pipes. At this time, the output end of the hydraulic rod is controlled to drive the connecting box to move downward, so that the two second stirring blades and the first stirring blade are inserted into the wastewater. There is a distance between the two second stirring blades, the two second stirring blades are located at the bottom layer of the wastewater, and the first stirring blade is located at the upper layer of the wastewater;

[0022] S2. At this time, a treatment agent is poured into the inside of the pool body, and then the external power switch of the driving motor is turned on to further drive the rotating rod to rotate, so that the first stirring blade rotates. The two second gears rotate driven by the first gear, and the two second stirring blades rotate through the two transmission rods. The first stirring blade stirs the wastewater near the upper layer, and the two second stirring blades stir the wastewater in the lower layer. The suspended substances on the water surface and the sediments in the deeper waters react with the agent in a fusion reaction. 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;

[0023] S3. When the round rod rotates clockwise, it drives a plurality of stirring plates and fan blades to rotate together. When the fan blades rotate clockwise, the air is pushed 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 through the exhaust holes on the hollow cylinder. At this time, the plurality of stirring plates stir the sodium hydroxide solid substance inside the cylinder, so that sodium hydroxide and hydrogen sulfide in the gas fully react in a fusion reaction to absorb hydrogen sulfide;

[0024] S4. After the wastewater in the pool body is treated, the external power switches of a plurality of delivery pumps are turned on. The wastewater treated in the pool body is discharged into a plurality of second diversion pipes through a plurality of first diversion pipes under the action of the plurality of delivery pumps, and further discharged into the purification pool for purification treatment;

[0025] S5. After the wastewater treatment is completed, turn on the external power switch of the bidirectional motor. The output shaft of the bidirectional motor can rotate forward and backward, further driving the threaded rod to rotate in different directions. One side of the scraper is closely attached to the bottom of the pool body. When the sleeve moves, the scraper is driven to move through the connecting rod. The scraper scrapes the inner wall of the pool body and scrapes the sludge at the bottom of the pool body. At this time, the sewage inside the pool body is discharged through multiple sewage pipes.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows.

[0027] 1. When the present invention treats electroplating wastewater, the electroplating wastewater is discharged into the interior of the pool body through multiple water inlet pipes. At this time, the output end of the hydraulic rod is controlled to drive the connecting 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 two second stirring blades are located at the bottom layer of the wastewater, while the first stirring blade is located at the upper layer of the wastewater. At this time, the treatment agent is poured into the interior of the pool body. Then, turn on the external power switch of the driving motor, which further drives the rotating rod to rotate, causing the first stirring blade to rotate. The two second gears rotate driven by the first gear, and the two second stirring blades rotate through the two transmission rods. The first stirring blade stirs the wastewater near the upper layer, and the two second stirring blades stir the wastewater in the deeper layer, so that the suspended matter on the water surface and the sediment and the agent in the deeper water area are fully mixed and reacted. After the wastewater in the pool body is treated, turn on the external power switch of multiple delivery pumps. The treated wastewater in the pool body is discharged into the interior of multiple second diversion pipes through multiple first diversion pipes under the action of the multiple delivery pumps, and further discharged into the purification pool for purification treatment. Therefore, when the sedimentation tank treats electroplating wastewater, the treatment agent can be fully contacted with the pollutants in the water. Whether it is the suspended matter on the water surface or the sediment in the deeper water area, it can be evenly distributed and reacted, improving the use efficiency of the treatment agent and the reaction effect.

[0028] 2. When the present invention treats wastewater, solid sodium hydroxide is added to the interior of the cylinder by rotating the screw cap, and then the screw cap 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, causing the round rod to rotate clockwise. When the round rod rotates clockwise, it drives multiple stirring plates and fan blades to rotate together. When the fan blades rotate clockwise, the air is pushed from the front to the back, inhaling the gas generated by the wastewater treatment, and further discharging it into the interior of the cylinder through the exhaust holes on the hollow cylinder. At this time, multiple stirring plates stir the solid sodium hydroxide in the cylinder, so that sodium hydroxide and hydrogen sulfide in the gas are fully mixed and reacted, absorbing hydrogen sulfide and reducing the emission of hydrogen sulfide gas. Therefore, when treating wastewater, hydrogen sulfide in the gas is treated, improving the practicability of the sedimentation tank.

[0029] 3. After the wastewater treatment of the present invention is completed, the connecting rod can slide on the inner wall of the notch. The sleeve and the connecting rod are connected together. Then, when the threaded rod rotates in different directions, the sleeve moves to different positions on the outer surface of the threaded rod. At this time, turn on the external power switch of the bidirectional motor, and the output shaft of the bidirectional motor can rotate forward and backward, further driving the threaded rod to rotate in different directions. One side of the scraper is closely attached to the bottom of the pool body. When the sleeve moves, the scraper is driven to move through the connecting rod. The scraper scrapes the inner wall of the pool body and scrapes 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 using the sedimentation tank, the sedimentation tank is convenient to clean.

[0051] Please refer to Figure 1 - Figure 10 In one embodiment, a hollow cylinder 3 is arranged on one side of the connection box 203 through screws. A round rod 301 is arranged at the center of one side of the hollow cylinder 3 through a bearing. A fan blade 306 is installed on one side of the round rod 301. The hollow cylinder 3 is above the water surface. The hollow cylinder 3 can be removed from the connection box 203 by rotating the screws. The round rod 301 can rotate through the bearing. When the fan blade 306 rotates clockwise, the air is pushed from the front to the rear, sucking in the gas generated by the wastewater treatment.

[0052] Please refer to Figure 1 - Figure 10, in one embodiment, a second pulley 304 is fixedly sleeved on the outer surface of the fan blade 306. A belt 303 is arranged on the outer surface of the second pulley 304. A first pulley 302 is arranged on the inner wall of the belt 303. The inner wall of the first pulley 302 is fixedly sleeved on the outer surface of the rotating rod 205.

When the fan blade 306 rotates clockwise, the air is pushed from the front to the back, and the gas generated by the wastewater treatment is inhaled, and then discharged into the inside of the cylinder 305 through the exhaust holes on the hollow cylinder 3. At this time, a plurality of stirring plates 307 stir the sodium hydroxide solid substance inside the cylinder 305, so that the sodium hydroxide and hydrogen sulfide in the gas are fully fused and react to absorb hydrogen sulfide and reduce the emission of hydrogen sulfide gas.

[0053] Please refer to Figure 1 - Figure 10 , in one embodiment, a plurality of stirring plates 307 are fixedly sleeved on the outer surface of the round rod 301. A cylinder 305 is fixedly arranged on one side of the hollow cylinder 3. A rotary cover 308 is arranged on one side of the cylinder 305. A plurality of exhaust holes are opened on one side of the hollow cylinder 3 and the rotary cover 308. Sodium hydroxide solid substance is added into the inside of the cylinder 305 by rotating the rotary cover 308, and then the rotary cover 308 is rotated to cover it on the cylinder 305. The plurality of exhaust holes opened on one side of the hollow cylinder 3 and the rotary cover 308 facilitate the passage of gas.

[0054] Please refer to Figure 1 - Figure 10 , in one embodiment, a protection box 4 is arranged on one side of the pool body 1. The two sides of the inner wall of the protection box 4 are provided with a threaded rod 401 through bearings. A plurality of sewage discharge pipes 406 are installed on one side of the pool body 1. The threaded rod 401 can rotate through the bearing. The protection box 4 protects the internal structure.

[0055] Please refer to Figure 1 - Figure 10 , in one embodiment, a sleeve 402 is threadedly sleeved on the outer surface of the threaded rod 401. A connecting rod 403 is fixedly arranged on the outer surface of the sleeve 402. When the threaded rod 401 rotates, the sleeve 402 does not rotate together. The sleeve 402 moves on its outer surface. When the sleeve 402 moves, the connecting rod 403 is driven to move.

[0056] Please refer to Figure 1 - Figure 10, in one embodiment, a scraper 404 is provided at one end of the connecting rod 403, and a bidirectional motor 405 is installed on one side of the protection box 4. The output shaft of the bidirectional motor 405 is connected to one side of the threaded rod 401. By turning on the external power switch of the bidirectional motor 405, the output shaft of the bidirectional motor 405 can rotate forward and backward, further driving the threaded rod 401 to rotate in different directions.

[0057] Please refer to Figure 1 - Figure 10 , in one embodiment, a notch 407 is formed on one side of the protection box 4. The connecting rod 403 is slidably arranged on the inner wall of the notch 407, and the scraper 404 is movably embedded on the inner wall of the pool body 1. The connecting rod 403 can slide on the inner wall of the notch 407. The sleeve 402 and the connecting rod 403 are connected together. Thus, when the threaded rod 401 rotates in different directions, the sleeve 402 moves to different positions on the outer surface of the threaded rod 401. One side of the scraper 404 is closely attached to the bottom of the pool body 1 of the pool body 1, scraping the sludge at the bottom of the pool body 1 of the pool body 1.

[0058] Working principle: When treating electroplating wastewater, the electroplating wastewater is discharged into the interior of the pool body 1 through a plurality of water inlet pipes 214. At this time, by controlling the output end of the hydraulic rod 202 to drive the connection box 203 to move downward, the fixed ring 201 has a supporting effect on the hydraulic rod 202, so that the hydraulic rod 202 is installed on the bracket 2, and 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. 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. At this time, treatment agents are poured into the interior of the pool body 1. Then, by turning on the external power switch of the driving motor 204, the rotating rod 205 is further driven to rotate, so that the first stirring blade 206 rotates. The two second gears 209 are driven to rotate by the first gear 207. Through the two transmission rods 208, the two second stirring blades 210 rotate. The first stirring blade 206 stirs the wastewater near the upper layer, and the two second stirring blades 210 stir the wastewater in the lower layer, so that the suspended matter on the water surface and the sediment in the deeper water area and the agent are fully mixed and reacted. After the wastewater in the pool body 1 is treated, by turning on the external power switch of a plurality of delivery pumps 215, the treated wastewater in the pool body 1 is discharged into the interior of a plurality of second diversion pipes 212 through a plurality of first diversion pipes 211 under the action of the plurality of delivery pumps 215, and further discharged into the interior of the purification tank 213 for purification treatment. Thus, when the sedimentation tank treats electroplating wastewater, the agent can be fully contacted with the pollutants in the water. Whether it is the suspended matter on the water surface or the sediment in the deeper water area, it can be evenly distributed and reacted, improving the use efficiency of the agent and the reaction effect;

[0059] When treating wastewater, sodium hydroxide solid substance is added into the interior of the cylinder 305 by rotating the rotary cover 308, and then the rotary cover 308 is rotated to cover it on the cylinder 305. The hollow cylinder 3 is above the water surface. When the rotating rod 205 drives the first stirring blade 206 to rotate clockwise, it will drive the first pulley 302 to rotate clockwise, and further drive the second pulley 304 to rotate through the belt 303, so that the round rod 301 rotates clockwise. When the round rod 301 rotates clockwise, it drives a plurality of stirring plates 307 and fan blades 306 to rotate together. When the fan blades 306 rotate clockwise, the air is pushed from the front to the rear, sucking in the gas generated by wastewater treatment, and further discharging it into the interior of the cylinder 305 through the exhaust holes on the hollow cylinder 3. At this time, a plurality of stirring plates 307 stir the sodium hydroxide solid substance in the cylinder 305, so that sodium hydroxide and hydrogen sulfide in the gas are fully fused and reacted to absorb hydrogen sulfide, reducing the emission of hydrogen sulfide gas. Thus, when treating wastewater, hydrogen sulfide in the gas is treated, improving the practicability of the sedimentation tank;

[0060] After the wastewater treatment is completed, the connecting rod 403 can slide on the inner wall of the notch 407. 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 direction positions 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 backward, further driving the threaded rod 401 to rotate in different directions. One side of the scraping plate 404 is closely attached to the bottom of the tank body 1. When the sleeve 402 moves, it drives the scraping plate 404 to move through the connecting rod 403. The scraping plate 404 scrapes the inner wall of the tank body 1 and scrapes the sludge at the bottom of the tank body 1 of the tank body 1. At this time, the sewage inside the tank body 1 is discharged through a plurality of sewage pipes 406. Thus, when using the sedimentation tank, the sedimentation tank is convenient to clean.
