Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to a graded treatment device and method for acidic mine water. Background Technology

[0002] Mine wastewater is a general term for natural dissolved water in mines, mineral processing wastewater, overflow water from mineral processing slag dikes, and leachate from slag heaps. Mine water mainly consists of surface seepage water, rock pore water, and mine pit water generated during mining operations. Acidic mine water is acidic, and during treatment, impurities such as high iron, high manganese, and high sulfate in the water need to be removed.

[0003] In existing technologies, when treating wastewater, the reagents are usually poured into the water tank all at once and then stirred by a stirring structure, which makes it difficult to allow the reagents to react fully with the water in the treatment tank quickly. Summary of the Invention

[0004] In view of the technical problem in the prior art, when treating wastewater, the agent is usually poured into the water tank all at once and then stirred by a stirring structure, which makes it difficult to quickly and fully react the agent with the water in the treatment tank. The present invention provides an acidic mine water classification treatment device and treatment method.

[0005] The technical solution adopted in this invention is: an acidic mine water classification treatment device, including a treatment tank, in which a first partition and a second partition are fixedly connected, dividing the treatment tank into a first treatment chamber, a second treatment chamber, and a third treatment chamber.

[0007] In one embodiment, the driving and walking assembly includes a rotating rod rotatably connected to a moving frame, a driving gear fixedly connected to the outside of the rotating rod, and a rack fixedly connected to the outside of a third processing chamber. The rack meshes with the driving gear. A control module is fixedly connected to the outside of the processing chamber. A first ranging sensor and a second ranging sensor are fixedly installed at both ends of the third processing chamber, respectively.

[0008] In one embodiment, a guide sleeve is fixedly connected to the outside of the movable frame, and a limit rod is fixedly connected to the outside of the third processing chamber, the limit rod passing through the guide sleeve.

[0009] In one embodiment, the stirring assembly includes a stirring rod rotatably connected to the bottom of a movable frame and multiple sets of stirring blades fixedly connected to the outside of the stirring rod. A motor is fixedly connected to the movable frame, a second bevel gear is fixedly connected to the output end of the motor, a first bevel gear is fixedly connected to the outside of the rotating rod, and a third bevel gear is fixedly connected to the top of the stirring rod. The first bevel gear meshes with the second bevel gear and the third bevel gear respectively, and the motor is electrically coupled to a control module.

[0010] In one embodiment, a fixing rod is fixedly connected to the top of the movable frame, a fixing ring is fixedly connected to the outside of the fixing rod, and a fixing seat is also fixedly connected to the outside of the movable frame.

[0011] In one embodiment, the treatment agent addition assembly includes a storage hopper, a sliding sleeve fitted at the bottom of the storage hopper, and a discharge pipe fixedly connected to the outside of the fixed base. The discharge pipe has multiple sets of through holes on its outside. The storage hopper is fixedly connected to a fixed ring. A connecting rod is fixedly connected inside the sliding sleeve, and a sealing column is fixedly connected to the top of the connecting rod.

[0012] In one embodiment, two sets of guide rods are fixedly connected to the top of the movable frame, and a connecting plate is sleeved on the outside of the guide rods. A synchronization plate is also provided on the top of the movable frame. A pin is fixedly connected between the synchronization plate and the connecting plate. A roller is rotatably connected to the outside of the pin. A spring is sleeved on the outside of the guide rods. A horizontal plate is fixedly connected to the top of the third processing chamber at the position corresponding to the roller. At least one arc-shaped protrusion is fixedly connected to the bottom of the horizontal plate. The roller is connected to the connecting plate, and the connecting plate drives the sliding sleeve to move downward.

[0013] In one embodiment, a first conveying pipe is fixedly connected to the outside of the third processing chamber, the filtration assembly is a filter box, one end of the first conveying pipe is fixedly connected to the filter box, a second conveying pipe is fixedly connected to the outside of the filter box, and activated carbon adsorption material is installed inside the filter box.

[0014] In one embodiment, a treatment method for acidic mine water classification treatment device includes the following steps:

[0015] The acidic mine wastewater is transported to the first treatment chamber for sedimentation treatment, and then pumped to the second treatment chamber by a water pump.

[0016] Alkaline agents are added to the second treatment chamber to neutralize the pH value of the acidic mine wastewater;

[0017] The acidic mine wastewater in the second treatment chamber is then pumped to the third treatment chamber using a water pump.

[0018] When the motor is started, it drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate, which in turn drives the third bevel gear to rotate. The first bevel gear drives the rotating rod to rotate, which in turn drives the gear to rotate. The gear, through meshing with the rack, drives the moving frame to move linearly on the top of the third treatment chamber. At the same time, the third bevel gear drives the stirring rod to rotate, which in turn drives the stirring blades to rotate, thus stirring the acidic mine wastewater in the third treatment chamber.

[0019] When the mobile frame moves on top of the third treatment chamber, the rollers will abut against the bottom of the arc-shaped protrusion. The arc-shaped protrusion abuts against the synchronous plate and the connecting plate and moves downward. The connecting plate drives the sliding sleeve to move downward. After the sliding sleeve moves downward, the sealing column will no longer block the bottom outlet of the storage hopper, so that the agent in the storage hopper can fall into the discharge pipe and be discharged into the third treatment chamber through the through hole on the outside of the discharge pipe. The addition of the treatment agent can react and remove the iron, manganese and sulfate components in the acidic mine wastewater.

[0020] When the roller no longer contacts the arc-shaped protrusion, the sliding sleeve moves upward under the force of the spring. The sliding sleeve drives the sealing column to seal the outlet at the bottom of the storage hopper again. This process is repeated, and the agent is added intermittently as the moving frame moves.

[0021] The acidic mine wastewater in the third treatment chamber is then transported to the filter box for filtration before being discharged.

[0022] The beneficial effects of this invention are:

[0023] 1. Compared with the prior art, in this invention, the first treatment chamber can be used to precipitate acidic mine wastewater, the second treatment chamber can be used to adjust the pH value of acidic mine wastewater, the driving walking component can drive the moving frame to move on top of the third treatment chamber, and drive the stirring component to move, so that the stirring component can fully stir the acidic mine wastewater. In addition, the treatment agent adding component can be added intermittently to the third treatment chamber when the moving frame moves, so that the acidic mine wastewater and the agent can fully react.

[0024] 2. Compared with the prior art, in this invention, a motor drives a second bevel gear to rotate, which in turn drives a first bevel gear to rotate, which in turn drives a third bevel gear to rotate. The first bevel gear drives a rotating rod to rotate, which in turn drives a gear to rotate. The gear, through meshing with a rack, causes the moving frame to move linearly at the top of the third treatment chamber. Simultaneously, the third bevel gear drives a stirring rod to rotate, which in turn drives a stirring blade to rotate, thus stirring the acidic mine wastewater in the third treatment chamber. When the moving frame moves at the top of the third treatment chamber, the rollers abut against the bottom of the arc-shaped protrusion. The arc-shaped protrusion abuts against the synchronous plate and connecting plate, causing them to move downwards. The connecting plate drives the sliding sleeve to move downwards, and the sliding sleeve moves towards... After the downward movement, the sealing column is no longer blocked from the bottom outlet of the storage hopper, allowing the reagent in the storage hopper to fall into the discharge pipe and be discharged into the third treatment chamber through the external through-hole of the discharge pipe. The addition of the treatment reagent can react and remove iron, manganese, and sulfate components in the acidic mine wastewater. When the roller no longer contacts the arc-shaped protrusion, the sliding sleeve moves upward under the elastic force of the spring. The sliding sleeve drives the sealing column to block the bottom outlet of the storage hopper again. This process is repeated, and the reagent is added intermittently as the moving frame moves. In summary, the reagent can be added to the third treatment chamber while the moving frame is moving, and then the stirring blades can be used to stir the reagent to allow it to fully react with the acidic mine wastewater.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] The following is in conjunction with the appendix Figure 1-13 The present invention will be further described below.

[0051] To address the problems existing in the background art, this application proposes the following technical solution: an acidic mine water classification treatment device, including a treatment tank 100, a climbing ladder 1006 fixedly connected to the outside of the treatment tank 100, and a first partition 1001 and a second partition 1002 fixedly connected inside the treatment tank 100. The first partition 1001 and the second partition 1002 divide the treatment tank 100 into a first treatment chamber 1003, a second treatment chamber 1004 and a third treatment chamber 1005. The first treatment chamber 1003 is used for sedimentation treatment of acidic mine wastewater, while the second treatment chamber 1004 is used for pH adjustment of acidic mine wastewater, for example, by adding sodium hydroxide solution to the second treatment chamber 1004.

[0052] In a further design, a pumping assembly for pumping water is provided outside the treatment tank 100. Specifically, the pumping assembly is a water pump 200 fixedly connected to the bottom of the treatment tank 100. The input end of the water pump 200 is fixedly connected to a first pipe 2001, and the output end of the water pump 200 is fixedly connected to a second pipe 2002. The second pipe 2002 is fixedly connected to the inside of the third treatment chamber 1005. A first absorption pipe 2005 and a second absorption pipe 2007 are fixedly connected to the outside of the first pipe 2001. The first absorption pipe 2005 is fixedly connected to the inside of the first treatment chamber 1003, and the second absorption pipe 2007 is fixedly connected to the outside of the first pipe 2001. 007 is fixedly connected to the second processing chamber 1004. A second valve 2004 is fixedly connected to the first pipe 2001, a first valve 2003 is fixedly connected to the second pipe 2002, a third valve 2006 is fixedly connected to the first absorption pipe 2005, and a fourth valve 2008 is fixedly connected to the second absorption pipe. A submersible pump is installed in the first processing chamber 1003. A water pipe is fixedly connected to the output end of the submersible pump. One end of the water pipe extends into the second processing chamber 1004. The submersible pump is not shown in the figure, but it is an existing product. Those skilled in the art can understand it based on the text description.

[0053] The above technical solution is explained as follows: by opening the first valve 2003, the second valve 2004, and the fourth valve 2008, and starting the water pump 200, the acidic mine wastewater in the second treatment chamber 1004 can be transported to the third treatment chamber 1005. At the same time, if the acidic mine wastewater has few impurities and does not require sedimentation treatment, the acidic mine wastewater in the first treatment chamber 1003 can also be pumped to the third treatment chamber by opening the third valve 2006. The acidic mine wastewater in the first treatment chamber 1003 can be transported to the second treatment chamber 1004 by turning on the submersible pump.

[0054] In a further design, a movable frame 300 is provided outside the third processing chamber 1005, a driving and walking component is provided outside the movable frame 300, a stirring component is provided at the bottom of the movable frame 300, a treatment agent addition component is also provided outside the movable frame 300, and a filtration component for filtering water is provided outside the processing tank 100.

[0055] Specifically, the driving and walking assembly includes a rotating rod 3001 rotatably connected to the movable frame 300, a driving gear 3002 fixedly connected to the outside of the rotating rod 3001, and a rack 3003 fixedly connected to the outside of the third processing chamber 1005. The rack 3003 meshes with the driving gear 3002. Through the meshing of the gear and the rack 3003, when the gear rotates, it can drive the movable frame 300 to move on the top of the third processing chamber 1005.

[0056] Among them, a guide sleeve 30011 is fixedly connected to the outside of the movable frame 300, and a limit rod 30010 is fixedly connected to the outside of the third processing chamber 1005. The limit rod 30010 passes through the guide sleeve 30011 and is used to guide the movable frame 300 to move.

[0057] In a further design, in this embodiment, the stirring assembly includes a stirring rod 3005 rotatably connected to the bottom of the movable frame 300 and multiple sets of stirring blades 3006 fixedly connected to the outside of the stirring rod 3005. A motor 3004 is fixedly connected to the movable frame 300. A second bevel gear 3008 is fixedly connected to the output end of the motor 3004. A first bevel gear 3007 is fixedly connected to the outside of the rotating rod 3001. A third bevel gear 3009 is fixedly connected to the top of the stirring rod 3005. The first bevel gear 3007 meshes with the second bevel gear 3008 and the third bevel gear 3009 respectively. 004 drives the second bevel gear 3008 to rotate, the second bevel gear 3008 drives the first bevel gear 3007 to rotate, the first bevel gear 3007 drives the third bevel gear 3009 to rotate, the first bevel gear 3007 drives the rotating rod 3001 to rotate, the rotating rod 3001 drives the gear to rotate, and the gear, through meshing with the rack 3003, drives the moving frame 300 to move linearly at the top of the third treatment chamber 1005. At the same time, the third bevel gear 3009 drives the stirring rod 3005 to rotate, and the stirring rod 3005 drives the stirring blade 3006 to rotate, thus stirring the acidic mine wastewater in the third treatment chamber 1005.

[0058] To facilitate the detection of the moving distance of the moving frame 300, a control module is fixedly connected to the outside of the processing tank 100. A first ranging sensor 700 and a second ranging sensor 800 are fixedly installed at both ends of the third processing chamber 1005, respectively. The motor 3004 is electrically coupled to the control module. When the moving frame 300 moves on the top of the third processing chamber 1005, the position of the moving frame 300 can be detected by the cooperation of the first ranging sensor 700 and the second ranging sensor 800. When the moving frame 300 approaches the edge, the control module can control the motor 3004 to flip, realizing reciprocating movement in the opposite direction. The ranging sensor can be a laser ranging sensor, and the control module can be an MCU control component or other control components.

[0059] In a further design, a fixing rod 4005 is fixedly connected to the top of the movable frame 300, and a fixing ring 4006 is fixedly connected to the outside of the fixing rod 4005. A fixing seat 4007 is also fixedly connected to the outside of the movable frame 300. In addition, the treatment agent addition component includes a storage hopper 500, a sliding sleeve 5001 fitted on the bottom of the storage hopper 500, and a discharge pipe 5002 fixedly connected to the outside of the fixing seat 4007. The discharge pipe 5002 has multiple sets of through holes 5003 on its outside. The storage hopper 500 is fixedly connected to the fixing ring 4006. A connecting rod 5005 is fixedly connected inside the sliding sleeve 5001. A sealing column 5004 is fixedly connected to the top of the connecting rod 5005. In the initial state, the sealing column 5004 seals the outlet at the bottom of the storage hopper 500, so that the agent in the storage hopper 500 cannot leak out.

[0060] Two sets of guide rods 4004 are fixedly connected to the top of the movable frame 300. A connecting plate 4001 is sleeved on the outside of the guide rods 4004. A synchronization plate 400 is also provided on the top of the movable frame 300. A pin 4008 is fixedly connected between the synchronization plate 400 and the connecting plate 4001. A roller 4002 is rotatably connected to the outside of the pin 4008. A spring 4003 is sleeved on the outside of the guide rods 4004. A horizontal plate 600 is fixedly connected to the top of the third processing chamber 1005 at the position corresponding to the roller 4002. At least one arc-shaped protrusion 6001 is fixedly connected to the bottom of the horizontal plate 600. The roller 4002 is connected to the connecting plate 4001. The connecting plate 4001 drives 5001 to move downward.

[0061] The above technical solution is explained as follows: When the moving frame 300 moves on top of the third treatment chamber 1005, the roller 4002 will abut against the bottom of the arc-shaped protrusion 6001. The arc-shaped protrusion 6001 abuts against the synchronous plate 400 and the connecting plate 4001 and moves downward. The connecting plate 4001 drives the sliding sleeve 5001 to move downward. After the sliding sleeve 5001 moves downward, the sealing column 5004 will no longer block the bottom outlet of the storage hopper 500, so that the agent in the storage hopper 500 can fall into the discharge pipe 5002 and be discharged into the third treatment chamber 1005 through the through hole 5003 on the outside of the discharge pipe 5002. The addition of the treatment agent can react and remove the iron, manganese and sulfate components in the acidic mine wastewater.

[0062] In a further design, in order to filter impurities from the treated acidic mine wastewater, a first conveying pipe 9001 is fixedly connected to the outside of the third treatment chamber 1005. The filter assembly is a filter box 900. One end of the first conveying pipe 9001 is fixedly connected to the filter box 900. A second conveying pipe 9002 is fixedly connected to the outside of the filter box 900. Activated carbon adsorption material is installed inside the filter box 900. An electric butterfly valve is fixedly connected to the outside of the first conveying pipe 9001. The treated acidic mine wastewater enters the filter box 900, is filtered by the activated carbon, and is discharged through the second conveying pipe 9002.

[0063] The usage method of this embodiment includes the following steps:

[0064] Step 1: The acidic mine wastewater is transported to the first treatment chamber 1003 for sedimentation treatment, and then the acidic mine wastewater in the first treatment chamber 1003 is pumped to the second treatment chamber 1004 by the water pump 200.

[0065] Step 2: Add alkaline reagent to the second treatment chamber 1004 to neutralize the pH value of the acidic mine wastewater;

[0066] Step 3: The acidic mine wastewater in the second treatment chamber 1004 is pumped to the third treatment chamber 1005 by the water pump 200.

[0067] Step four: Start the motor 3004. The motor 3004 drives the second bevel gear 3008 to rotate, the second bevel gear 3008 drives the first bevel gear 3007 to rotate, the first bevel gear 3007 drives the third bevel gear 3009 to rotate, the first bevel gear 3007 drives the rotating rod 3001 to rotate, the rotating rod 3001 drives the drive gear 3002 to rotate, and the drive gear 3002, through meshing with the rack 3003, drives the moving frame 300 to move linearly at the top of the third treatment chamber 1005. At the same time, the third bevel gear 3009 drives the stirring rod 3005 to rotate, and the stirring rod 3005 drives the stirring blade 3006 to rotate, thus stirring the acidic mine wastewater in the third treatment chamber 1005.

[0068] Step 5: When the moving frame 300 moves at the top of the third treatment chamber 1005, the roller 4002 abuts against the bottom of the arc-shaped protrusion 6001. The arc-shaped protrusion 6001 abuts against the synchronous plate 400 and the connecting plate 4001 and moves downward. The connecting plate 4001 drives the sliding sleeve 5001 to move downward. After the sliding sleeve 5001 moves downward, the sealing column 5004 no longer blocks the bottom outlet of the storage hopper 500, so the agent in the storage hopper 500 can fall into the discharge pipe 5002 and be discharged into the third treatment chamber 1005 through the through hole 5003 on the outside of the discharge pipe 5002. The addition of the treatment agent can react and remove the iron, manganese and sulfate components in the acidic mine wastewater. (The agent can be barium chloride, activated alumina or other treatment agents. Activated alumina removes dissolved iron, manganese and other metal ions in the water through physical adsorption. Barium chloride turns sulfate ions into barium sulfate precipitate, which is then filtered out.)

[0069] Step six: When the roller 4002 no longer contacts the arc-shaped protrusion 6001, the sliding sleeve 5001 moves upward under the elastic force of the spring 4003. The sliding sleeve 5001 drives the sealing column 5004 to seal the outlet at the bottom of the storage hopper 500 again. This process is repeated, and the medicine is added intermittently when the moving frame 300 moves.

[0070] Step seven: The acidic mine wastewater in the third treatment chamber 1005 is then transported to the filter box 900 for filtration before being discharged.

[0071] In summary, the reagent can be added to the third treatment chamber 1005 while the mobile frame 300 is moving, and then the reagent can be fully reacted with the acidic mine wastewater by the stirring blade 3006.

6. A treatment method for acidic mine water classification treatment device as described in claim 5, characterized in that, Includes the following steps: The acidic mine wastewater is transported to the first treatment chamber (1003) for sedimentation treatment, and the acidic mine wastewater in the first treatment chamber (1003) is pumped to the second treatment chamber (1004) by a submersible pump. An alkaline agent is added to the second treatment chamber (1004) to neutralize the pH value of the acidic mine wastewater; The acidic mine wastewater in the second treatment chamber (1004) is then pumped to the third treatment chamber (1005) by a water pump (200); The motor (3004) is started and operates. The motor (3004) drives the second bevel gear (3008) to rotate. The second bevel gear (3008) drives the first bevel gear (3007) to rotate. The first bevel gear (3007) drives the third bevel gear (3009) to rotate. The first bevel gear (3007) drives the rotating rod (3001) to rotate. The rotating rod (3001) drives the drive gear (3002) to rotate. The drive gear (3002) meshes with the rack (3003) to drive the moving frame (300) to move linearly at the top of the third treatment chamber (1005). At the same time, the third bevel gear (3009) drives the stirring rod (3005) to rotate. The stirring rod (3005) drives the stirring blade (3006) to rotate, thus stirring the acidic mine wastewater in the third treatment chamber (1005). When the moving frame (300) moves on top of the third processing chamber (1005), the roller (4002) will abut against the bottom of the arc-shaped protrusion (6001). The arc-shaped protrusion (6001) abuts against the roller (4002), causing the synchronous plate (400) and the connecting plate (4001) to move downward. The connecting plate (4001) drives the sliding sleeve (5001) to move downward. After the sliding sleeve (5001) moves downward, the sealing column (5004) will no longer block the bottom outlet of the storage hopper (500), so that the agent in the storage hopper (500) can fall into the discharge pipe (5002) and be discharged into the third processing chamber (1005) through the through hole (5003) outside the discharge pipe (5002). The addition of the treatment agent can react and remove the iron, manganese and sulfate components in the acidic mine wastewater. When the roller (4002) no longer contacts the arc-shaped protrusion (6001), the sliding sleeve (5001) moves upward under the elastic force of the spring (4003). The sliding sleeve (5001) drives the sealing column (5004) to seal the outlet at the bottom of the storage hopper (500) again. This process is repeated, and the intermittent addition of medicine is achieved when the moving frame (300) moves. The acidic mine wastewater in the third treatment chamber (1005) is then transported to the filter box (900) for filtration and then discharged.
