[0002] A large amount of acidic wastewater is generated during mining. This wastewater contains heavy metal ions and other harmful substances. If it is discharged directly into the environment without treatment, it will cause serious pollution to the soil and water sources. Traditional wastewater treatment methods often require the wastewater to be transported to specialized treatment facilities, which not only increases the treatment cost, but also makes it difficult to respond quickly in emergency situations.

[0017] Among them, the outer end of the connecting block 2 is fixedly connected to a cleaning tank 204 with a barrel structure, and the cleaning tank 204 is connected to each group of telescopic tubes 201; a filter plate 205 with a circular plate structure is fixedly provided inside the cleaning tank 204; a screw 206 is rotatably provided in the middle of the cleaning tank 204; a bottom plate 207 with a circular plate structure is slidably provided inside the cleaning tank 204, and the outer wall of the bottom plate 207 is fitted with the inner wall of the cleaning tank 204, and the bottom plate 207 is connected to the screw 206 by threaded cooperation; a water pump 208 is connected to the top of the cleaning tank 204; a return pipe 209 is connected to the top of the water pump 208, and one side of the return pipe 209 passes through the inside of the circular through groove on the right side of the fixed plate 101.

[0018] Specific usage and function of this embodiment: After the wastewater enters the tank body 1 and the sedimentation is completed, when it is necessary to clean the metal impurities in the wastewater, the first motor 102 can be started to drive the stirring roller 103 to rotate, and the magnetic material on the stirring roller 103 can be used to adsorb the metal impurities in the wastewater, so that the metal impurities are adsorbed on the stirring roller 103. When it is necessary to recover and clean these metal impurities, the second motor 112 can be started to drive the lead screw 113 to rotate, thereby driving the connecting block 2 to slide to one side along the fixed rod 110, so that each group of telescopic tubes 201 is inserted into the inner side of the tank body 1 along the rectangular through groove on one side of the tank body 1. During the rotation of the stirring roller 103, when the stirring roller 103 rotates to the inner side of the telescopic tube 201 and contacts the inclined surface structure of the two groups of scrapers 203, the two groups of scrapers 203 and the sliding rod 202 can be pushed to slide along the upper and lower sides of the telescopic tube 201 respectively, and on the outside of the sliding rod 202 Under the action of the spring, the two groups of scrapers 203 are closely fitted with the upper and lower sides of the stirring roller 103 respectively, so that the metal impurities adsorbed on the surface of the stirring roller 103 are scraped off by the two groups of scrapers 203, and the water pump 208 is started at the same time. The water flow and the scraped metal impurities are pumped into the cleaning tank 204 along the telescopic tube 201 and the inside of the connecting block 2 by the water pump 208, and these metal impurities are blocked and filtered by the filter plate 205. The water flow filtered by the filter plate 205 flows back to the tank body 1 through the return pipe 209. The metal impurities retained in the cleaning tank 204 can be driven by the rotating screw 206 to drive the bottom plate 207 to move downward, so as to clean the impurities inside the cleaning tank 204, thereby completing the process of cleaning and collecting metal impurities in the wastewater. In the whole process, the metal impurities remaining in the wastewater can be quickly and effectively collected, which greatly improves the cleaning efficiency of the metal impurities in the wastewater.

[0019] Example 2: Based on Example 1, please refer to Figures 1 to 8 : Among them, a fixing plate 101 of a U-shaped plate structure is fixedly provided on the top of the tank body 1, and a through-type circular through groove structure is opened on the right side of the fixing plate 101; a first motor 102 is fixedly provided in the middle of the top of the fixing plate 101; a stirring roller 103 is rotatably provided at the bottom of the fixing plate 101, and the stirring roller 103 is made of magnetic material, and the stirring roller 103 is transmission-connected to the first motor 102; a water inlet pipe 104 is fixedly installed on the top of the fixing plate 101; a fan blade 105 is rotatably provided on the inner side of the bottom end of the water inlet pipe 104; a connecting shaft 106 of an L-shaped rod structure is fixedly connected to the bottom of the fan blade 105, and a spring is sleeved on the outer side of the bottom end of the connecting shaft 106.

[0020] Among them, a medicine barrel 107 is rotatably arranged on the outer side of the bottom end of the water inlet pipe 104, and a rectangular medicine outlet structure is opened at the bottom of the medicine barrel 107; a slider 108 with a rectangular block structure is slidably arranged on the outer side of the ground end of the connecting shaft 106; a baffle 109 with an L-shaped plate structure is fixedly arranged on the top of the slider 108, and the baffle 109 is in contact with the opening at the bottom of the medicine barrel 107; a connecting plate 111 with an L-shaped plate structure is fixedly arranged on the right side of the tank body 1; a second motor 112 is fixedly arranged on the outer end of the connecting plate 111; a screw 113 is rotatably arranged on the inner side of the connecting plate 111, and the screw 113 is transmission-connected to the second motor 112, and the screw 113 is connected to the connecting block 2 by threaded matching.

[0021] Specific usage and function of this embodiment: In the present invention, first, the tank body 1 with a circular groove structure is placed in the treatment area to ensure that the tank body 1 is stable and can accommodate enough acidic wastewater; on the right side of the tank body 1, a fixed rod 110 with a cylindrical structure is fixedly installed to ensure that the fixed rod 110 is perpendicular to the surface of the tank body 1 to provide support for the sliding of the connecting block 2, and the connecting block 2 with a T-shaped block structure is slidably sleeved on the fixed rod 110, and is threadedly connected with the lead screw 113 through a screw hole structure, and on one side of the bottom of the connecting block 2, a telescopic tube 201 with an internal hollow rectangular rod structure is arranged and fixedly installed, and circular through grooves are provided on the upper and lower sides of the outer end of the telescopic tube 201 for installing the sliding rod 202 and the scraper 203; when it is necessary to treat the wastewater, the wastewater is added to the tank body 1 through the water inlet pipe 104, and flocculants and other medicines for precipitation are added to the medicine barrel 107. In the process of wastewater entering the tank body 1 through the water inlet pipe 104, it can impact and drive the fan blades 105 to rotate, thereby synchronously driving the connecting shaft 106 to rotate. If the water flow rate is small, the rotation speed of the fan blades 105 is slow. If the water flow rate is large, the rotation speed of the fan blades 105 will become faster. As the rotation speed increases, the rotation speed of the connecting shaft 106 will also increase, thereby increasing the centrifugal force generated by the connecting shaft 106, and then allowing the slider 108 to slide outward along the connecting shaft 106, and drive the baffle 109 to slide at the bottom opening of the medicine barrel 107, thereby making the opening of the medicine barrel 107 larger, and the amount of medicine output increases, so that the amount of medicine output of the medicine barrel 107 can increase with the increase of water flow, so as to achieve the purpose of self-adjustment according to the water flow, effectively ensure the effect of drug coagulation, and at the same time avoid the waste of drugs, thereby improving the use effect of the device.
