The waste water inside the filter barrel is thrown onto the inner wall of the filter barrel by centrifugal force. The diameter design of the first water outlet hole and the second water outlet hole in the filter barrel and the cleaning plate can filter out impurities such as FeS2 solid particles in the water. Due to the high-speed rotation of the filter barrel, the strong centrifugal force separates the FeS2 solid particles and other impurities from the water, which has the effect of quickly separating water and FeS2 solid particles and other impurities, and greatly shortens the time for filtering FeS2 solid particles and other impurities.

[0023] Third: a part of the waste water is thrown into the cleaning cylinder through the gap between the receiving cylinder and the cleaning cylinder. Due to the centrifugal force, a small amount of waste water inside the cleaning cylinder cannot flow down through the cleaning pipe, the main shaft and the filter barrel stop rotating, and a small amount of waste water inside the cleaning cylinder flows down through the cleaning pipe, continuously flushing the connecting pipe and the inner wall of the filter barrel, removing residual FeS2 solid particles and other impurities, and flushing away FeS2 solid particles and other impurities at the bottom of the filter barrel, cleaning the filter barrel and cleaning plate, playing the role of cleaning equipment, so that the equipment can be used for a long time.

[0036] The collection box 1 is provided with a pumping mechanism inside, which is used to deliver the sewage to a certain height;

[0037] A centrifugal decontamination mechanism is installed inside the filter housing 6, and the centrifugal decontamination mechanism is used to automatically remove the filtered soil impurities;

[0038] A centrifugal valve mechanism is installed on the top of the filter housing 6, and the centrifugal valve mechanism is used to control the injection of sewage according to the rotation speed;

[0039] A negative electrode collecting mechanism is installed on one side of the electrophoresis box 5, and the negative electrode collecting mechanism is used to reduce metal ions;

[0040] A positive electrode neutralization mechanism is installed on the other side of the electrophoresis box 5, and the positive electrode neutralization mechanism is used to neutralize sulfate ions in water;

[0041] A start-stop valve mechanism is installed on one side of the fixed plate 4, and the start-stop valve mechanism is used to control the discharge of treated water.

[0042] In this embodiment, the pyrite wastewater from the mine is pumped into a collection box 1, and impurities such as FeS2 solid particles are quickly removed by centrifugal force through a centrifugal decontamination mechanism, metal materials are recovered through a negative electrode collection mechanism, and the wastewater is harmlessly treated through a positive electrode neutralization mechanism.

[0043] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the pumping mechanism includes a fixed short plate 8 fixedly connected to the inner wall of one side of the collecting box 1, and a water pump 9 is fixedly connected to the upper surface of the fixed short plate 8. A water inlet and a water outlet are arranged on one side of the water pump 9. A water inlet pipe 10 is inserted on one side of the water inlet, and a water outlet pipe 7 is inserted on one side of the water outlet. The centrifugal decontamination mechanism includes a main shaft 37 rotatably connected to the center of the filter housing 6, a filter barrel 38 is fixedly connected to the outer wall of the main shaft 37, a plurality of first drainage holes are arranged on the outer wall of the filter barrel 38, a plurality of first drainage grooves are arranged on the bottom inner wall of the main shaft 37, a water storage cavity 39 is arranged inside the top end of the main shaft 37, and a plurality of first drainage holes are arranged on the inner wall of the water storage cavity 39. A water outlet hole, a receiving tube 41 is fixedly connected to the outer wall of the top end of the main shaft 37, and a plurality of second water outlet holes are arranged on the outer wall of the receiving tube 41, and two fixing blocks 47 are fixedly connected to the inner walls on both sides of the filter barrel 38, and a cleaning plate 50 is rotatably connected to one side of the fixing block 47, and a movable groove is opened on one side of the cleaning plate 50, and a blocking rod 49 is fixedly connected to one side of the movable groove, and a first centrifugal plate 45 is rotatably connected to the inner walls on both sides of the filter barrel 38, and a first centrifugal ball 46 is fixedly connected to one end of the first centrifugal plate 45, and a sliding groove 48 is opened at the other end of the first centrifugal plate 45, and a plurality of second drainage holes are arranged on the surface of the cleaning plate 50, and a linkage rod 52 is rotatably connected to the top of the cleaning plate 50;

[0044] A cleaning mechanism is installed at the top end of the main shaft 37, and the cleaning mechanism is used to clean the filtered soil impurities.

[0045] In this embodiment, the water pump 9 is started to pump out the wastewater through the water inlet pipe 10. Due to the design of the water storage cavity 39, the wastewater will gather in the water storage cavity 39, and the first water outlet on the water storage cavity 39 will discharge the wastewater into the receiving tube 41, and the wastewater will be discharged into the filter barrel 38 through the second water outlet on the receiving tube 41. At this time, the motor 11 is started, and the rotation of the motor 11 drives the rotating gear 42 and the main shaft 37 to rotate. When the speed is slow, the water inside the filter barrel 38 is thrown around by centrifugal force and cannot be discharged from the second sewage trough. The filter barrel 38 is filled with a certain amount of wastewater, and the motor 11 makes the speed of the main shaft 37 reach a critical value.

[0046] Furthermore, the first centrifugal ball 46 forces the first centrifugal plate 45 to rotate due to centrifugal force, so that the first centrifugal plate 45 pulls the cleaning plate 50 to rotate, and the cleaning plate 50 rotates to fit the inner wall of the filter barrel 38. The linkage rod 52 causes the upper and lower cleaning plates 50 to rotate to fit the inner wall of the filter barrel 38. The waste water inside the filter barrel 38 is thrown onto the inner wall of the filter barrel 38 by the centrifugal force. Since the diameter design of the first water outlet hole and the second water outlet hole on the filter barrel 38 and the cleaning plate 50 can filter out impurities such as FeS2 solid particles in the water, due to the high-speed rotating filter barrel 38, the strong centrifugal force separates the impurities such as FeS2 solid particles from the water, and the impurities such as FeS2 solid particles are filtered by the filter barrel 38 and the cleaning plate 50, which has the effect of quickly separating water and impurities such as FeS2 solid particles, and greatly shortens the time for filtering impurities such as FeS2 solid particles.

[0047] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 In a preferred embodiment, the cleaning mechanism includes a cleaning cylinder 44 fixedly connected to the outer side of the top of the receiving cylinder 41, and a plurality of cleaning pipes 51 are respectively inserted into the bottom of the cleaning cylinder 44.

[0048] In this embodiment, a portion of the waste water is thrown into the cleaning cylinder 44 through the gap between the receiving cylinder 41 and the cleaning cylinder 44. Due to the centrifugal force, a small amount of waste water inside the cleaning cylinder 44 cannot flow down through the cleaning pipe 51, and the main shaft 37 and the filter barrel 38 stop rotating. A small amount of waste water inside the cleaning cylinder 44 flows down through the cleaning pipe 51, continuously flushing the inner wall of the connecting pipe 20 and the filter barrel 38, removing residual FeS2 solid particles and other impurities, and flushing away FeS2 solid particles and other impurities at the bottom of the filter barrel 38, cleaning the filter barrel 38 and the cleaning plate 50, thereby cleaning the equipment and allowing the equipment to be used for a long time.

[0049] It is also necessary to explain that after FeS2 solid particles are collected, they need to be isolated from the air as much as possible, otherwise FeS2 will oxidize to produce sulfur dioxide gas.

[0050] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 In a preferred embodiment, the centrifugal valve mechanism includes a second valve 53 fixedly connected to the top of the main shaft 37, a mounting plate fixedly connected to the outer side of the bottom of the second valve 53, and connecting plates 59 on both sides are fixedly connected to the upper surface of the mounting plate. An active plate 57 is rotatably connected to one side of the connecting plate 59, and a second centrifugal ball 58 is fixedly connected to one end of the active plate 57, and a ball head shell is fixedly connected to the other end of the active plate 57. A second valve ball 55 is rotatably connected to the inside of the second valve 53, and a through hole is opened inside the second valve ball 55. Short rods are fixedly connected to both sides of the second valve ball 55, and one end of the short rod is fixedly connected to a second centrifugal plate 54. A valve spring 60 is fixedly connected to one end of the second centrifugal plate 54, and an auxiliary rod 56 is fixedly connected to one side of the second centrifugal plate 54. A ball head is fixedly connected to one end of the auxiliary rod 56, and the ball head can roll in the ball head shell.

[0051] In this embodiment, waste water is discharged into the second valve 53 through the outlet pipe 7. Since the main shaft 37 is in a stopped state, the position of the through hole on the second valve ball 55 is aligned with the hole on the second valve 53, so that the second valve 53 is in a conducting state, and the waste water flows into the main shaft 37 through the second valve ball 55 and the second valve 53. The rotation speed of the main shaft 37 reaches a critical value, and the second centrifugal ball 58 forces the active plate 57 to rotate due to the centrifugal force. The active plate 57 and the second centrifugal plate 54 are deflected, so that the second valve ball 55 rotates inside the second valve 53, and the position of the through hole on the second valve ball 55 is offset, so as to reach a certain speed and thus cut off the waterway.

[0052] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the negative electrode collection mechanism includes a negative electrode 19 fixedly connected to the inner wall of one side of the electrophoresis box 5, and one side of the negative electrode 19 is electrically connected to a plurality of electrode rods 18.

A positive electrode plate 14 is fixedly connected to the bottom inner wall of the electrophoresis box 5 at a position inside the gathering box 16.

[0053] In this embodiment, the filtered wastewater is discharged into the electrophoresis box 5 through the water pipe 12. The wastewater inside the electrophoresis box 5 contains various metal cations and sulfate ions. By applying negative electricity to the negative electrode 19 and the electrode rod 18 and applying positive electricity to the positive plate 14, the metal cations in the wastewater in the electrophoresis box 5 will be screened by the cation selective membrane 17 and gathered on the negative electrode 19 and the electrode rod 18. The metal ions undergo a reduction reaction on the negative electrode 19 and the electrode rod 18 to precipitate metal elements, thereby recovering metal materials. The sulfate ions pass through the screening of the anion selective membrane and enter the interior of the anion selective membrane, and enter the gathering box 16 through the AC hole 15, and react with the alkaline solution near the positive plate 14 to generate salt and water. The purified water is discharged through the connecting pipe 20, thereby quickly purifying the wastewater.

[0055] In this embodiment, when the motor 11 rotates, it will drive the rotating rod 31 and the threaded groove cylinder 33 to rotate, and the threaded groove cylinder 33 and the guide rod 32 cooperate. When the rotating rod 31 rotates, the threaded groove on the threaded groove cylinder 33 makes the guide rod 32 always deviate to the right side of the threaded groove cylinder 33, thereby pulling the connecting rod 26 to slide to the right, pulling the sliding rod 25 and the baffle 22, compressing the reset spring 27, and causing the rotating plate 28 and the first valve ball 29 to deflect, thereby cutting off the water path between the connecting pipe 20 and the drain pipe 23. After the motor 11 stops rotating, the purified water is discharged through the connecting pipe 20, the first valve 21 and the drain pipe 23. Through this design, when the wastewater is filtered, there is enough time to treat the wastewater in the electrophoresis box 5, so as to achieve the effect of thoroughly cleaning the wastewater.

[0056] Working principle: When in use, the pyrite wastewater from the mine is pumped into the collection box 1, the water pump 9 is started, the wastewater is pumped out through the water inlet pipe 10, and the wastewater is discharged into the second valve 53 through the water outlet pipe 7. Since the main shaft 37 is in a stopped state, the through hole position on the second valve ball 55 is aligned with the hole on the second valve 53, so that the second valve 53 is in a conducting state, and the wastewater flows into the main shaft 37 through the second valve ball 55 and the second valve 53. Due to the design of the water storage cavity 39, the wastewater will be collected in the water storage cavity 39, and the first water outlet hole on the water storage cavity 39 will discharge the wastewater into the receiving tube 41, and the wastewater will be discharged into the filter barrel 38 through the second water outlet hole on the receiving tube 41. At this time, the motor 11 is started, and the rotation of the motor 11 drives the rotating gear 42 and the main shaft 37 to rotate, and the speed is relatively high. When the filter barrel 38 is slow, the water inside the filter barrel 38 is thrown around by the centrifugal force and cannot be discharged from the second sewage tank. The filter barrel 38 is filled with a certain amount of waste water, and the motor 11 makes the speed of the main shaft 37 reach a critical value. The first centrifugal ball 46 forces the first centrifugal plate 45 to rotate due to the centrifugal force, so that the first centrifugal plate 45 pulls the cleaning plate 50 to rotate, and the cleaning plate 50 rotates to fit the inner wall of the filter barrel 38. The linkage rod 52 makes the upper and lower cleaning plates 50 rotate to fit the inner wall of the filter barrel 38. The second centrifugal ball 58 forces the active plate 57 to rotate due to the centrifugal force. The active plate 57 links the second centrifugal plate 54 to deflect, so that the second valve ball 55 rotates inside the second valve 53, and the position of the through hole on the second valve ball 55 is offset, so as to reach a certain speed. The water channel is cut off, and the waste water inside the filter barrel 38 is thrown onto the inner wall of the filter barrel 38 by the centrifugal force. Since the diameter design of the first water outlet hole and the second water outlet hole on the filter barrel 38 and the cleaning plate 50 can filter out impurities such as FeS2 solid particles in the water, due to the high-speed rotation of the filter barrel 38, the strong centrifugal force separates the FeS2 solid particles and other impurities from the water, and the FeS2 solid particles and other impurities are filtered by the filter barrel 38 and the cleaning plate 50, which has the effect of quickly separating water and FeS2 solid particles and other impurities, greatly shortening the time for filtering FeS2 solid particles and other impurities. A part of the waste water is thrown into the cleaning barrel 44 through the gap between the receiving barrel 41 and the cleaning barrel 44. Due to the action of centrifugal force, a small amount of impurities inside the cleaning barrel 44 Wastewater cannot flow down through the cleaning pipe 51, and the motor 11 is turned off to stop the main shaft 37 and the filter barrel 38 from rotating. The first centrifugal ball 46 restores the first centrifugal plate 45 to its original position due to gravity, causing the upper and lower cleaning plates 50 to deflect, and the FeS2 solid particles and other impurities filtered on the cleaning plate 50 fall to the bottom of the filter barrel 38. A small amount of wastewater inside the cleaning cylinder 44 flows down through the cleaning pipe 51, continuously flushing the inner wall of the connecting pipe 20 and the filter barrel 38, removing the remaining FeS2 solid particles and other impurities, and flushing away the FeS2 solid particles and other impurities at the bottom of the filter barrel 38, cleaning the filter barrel 38 and the cleaning plate 50, playing the role of cleaning the equipment, so that the equipment can be used for a long time, and the filtered wastewater is discharged into the electrophoresis box 5 through the water guide pipe 12.The wastewater in the electrophoresis box 5 contains various metal cations and sulfate ions. By applying negative electricity to the negative electrode 19 and the electrode rod 18 and applying positive electricity to the positive plate 14, the metal cations in the wastewater in the electrophoresis box 5 will be screened by the cation selection membrane 17 and gathered on the negative electrode 19 and the electrode rod 18. The metal ions will undergo a reduction reaction on the negative electrode 19 and the electrode rod 18 to precipitate metal elements, thereby recovering metal materials. The sulfate ions will pass through the screening of the anion selection membrane and enter the interior of the anion selection membrane, and enter the gathering box 16 through the AC hole 15. They will react with the alkaline solution near the positive plate 14 to generate salt and water. The purified water will be discharged through the connecting pipe 20. As the motor 11 rotates, It will drive the rotating rod 31 and the threaded groove cylinder 33 to rotate, and the threaded groove cylinder 33 and the guide rod 32 cooperate. When the rotating rod 31 rotates, the threaded groove on the threaded groove cylinder 33 makes the guide rod 32 always deviate to the right side of the threaded groove cylinder 33, thereby pulling the connecting rod 26 to slide to the right, pulling the sliding rod 25 and the baffle 22, thereby compressing the reset spring 27, causing the rotating plate 28 and the first valve ball 29 to deflect, thereby cutting off the water path between the connecting pipe 20 and the drain pipe 23. After the motor 11 stops rotating, the purified water is discharged through the connecting pipe 20, the first valve 21 and the drain pipe 23. Through this design, when the wastewater is filtered, there is enough time to treat the wastewater in the electrophoresis box 5, so as to achieve the effect of thoroughly cleaning the wastewater.
