The inner stirring blade 7 is movably inserted in the mounting groove 601. The outer stirring blade 6 and the inner stirring blade 7 have the same structural height to ensure that the inner stirring blade 7 will not be affected when the outer stirring blade 6 rotates. A first guide groove 602 is opened on the outer stirring blade 6, and a second guide groove 701 is opened on the inner stirring blade 7 at a position corresponding to the first guide groove 602. The shapes of the first guide groove 602 and the second guide groove 701 are adapted to each other. Through the cooperation of the second guide groove 701 and the first guide groove 602, the outer stirring blade 6 and the inner stirring blade 7 have a structural The size of the space through which the waste liquid flows is regulated. When the inner stirring blade 7 descends in the outer stirring blade 6, the scraper 702 contacts the upper surface of the impurity sedimentation plate 8 to scrape all the precipitated impurities into the impurity gathering groove 801. A scraper 702 is provided at the bottom of the inner stirring blade 7. An impurity sedimentation plate 8 is fixedly installed at the bottom of the inner wall of the sedimentation tank 1. The upper surface of the impurity sedimentation plate 8 is conical, which increases the sedimentation area and improves the sedimentation effect of impurities in the waste liquid. An impurity gathering groove 801 is provided on the upper surface of the impurity sedimentation plate 8. A trapezoidal limiting strip 802 is coaxially fixedly installed in the impurity gathering groove 801. The trapezoidal limiting strip 802 is trapezoidal to ensure the stability of the impurity push plate 9 sliding on the trapezoidal limiting strip 802. The impurity gathering groove 801 is slidably connected with the impurity push plate 9. The bottom of the impurity push plate 9 is opened A groove corresponding to the shape of the trapezoidal limit strip 802 is provided, and the impurity push plate 9 and the trapezoidal limit strip 802 are slidably connected to ensure the stability of the impurity push plate 9 during sliding. A driven wheel 10 and a driving wheel 11 are rotatably connected in the impurity sedimentation plate 8. A transmission belt 12 is provided between the driven wheel 10 and the driving wheel 11 for transmission connection.

The other end of the connecting belt 14 is transmission-connected to the driving wheel 11. The output shaft of the second servo motor 13 drives the connecting belt 14 to move, thereby driving the driving wheel 11 to rotate. The transmission belt 12 is driven by the rotation of the driving wheel 11.Thereby, the impurity push plate 9 is driven to move in the impurity gathering groove 801, and the movement of the impurity push plate 9 drives the movement of the precipitated impurities in the impurity gathering groove 801, ensuring the discharge of the precipitated impurities. A sealing plug 15 is movably inserted at the position corresponding to the bottom of the impurity gathering groove 801 on the sedimentation tank 1, and the sealing plug 15 is used to control the discharge of waste liquid at the corresponding position.

[0036] The opening direction of the impurity gathering groove 801 is the same as the radial direction of the arc surface of the impurity precipitation plate 8 , so as to ensure that the precipitated impurities fall into the impurity gathering groove 801 .

[0037] A first drainage groove 603 is provided on the outer stirring blade 6, and a second drainage groove 703 is provided on the inner stirring blade 7. The positions of the first drainage groove 603 and the second drainage groove 703 correspond to each other, and the first drainage groove 603 and the second drainage groove 703 are the same size, which reduces the overall weight of the structure composed of the outer stirring blade 6 and the inner stirring blade 7. At the same time, the design of the first guide groove 602 and the second drainage groove 703 can prevent the precipitated impurities at the bottom from being scraped up when the outer stirring blade 6 and the inner stirring blade 7 rotate.

[0038] An assembly buckle 16 is provided at the position of the sealing plug 15 on the outer wall of the sedimentation tank 1, and an arc-shaped sealing plate 17 is movably inserted in the assembly buckle 16. The positions of the arc-shaped sealing plate 17 and the sealing plug 15 correspond to each other. A third servo motor 18 is fixedly installed on the assembly buckle 16. The third servo motor 18 is transmission-connected to a driving wheel 19. The driving wheel 19 fits against the outer wall of the arc-shaped sealing plate 17. The third servo motor 18 drives the driving wheel 19 to rotate. The arc-shaped sealing plate 17 is driven to rotate by the relative friction between the driving wheel 19 and the arc-shaped sealing plate 17. In this way, the arc-shaped sealing plate 17 no longer blocks the sealing plug 15, and it is convenient to pull out the sealing plug 15.

[0039] A limit plate 20 is fixedly installed on the outer wall of the sedimentation tank 1 at a position corresponding to the moving track of the assembly buckle 16. The limit plate 20 limits the movement of the arc-shaped sealing plate 17 to ensure that the movement of the arc-shaped sealing plate 17 does not exceed a specified range.

[0040] A flip plate 21 is installed at a position near the top of the outer wall of the outer stirring blade 6 through a hinge, and a fixed shaft 22 is fixedly installed on the outer stirring blade 6. An adjustable clip 23 is rotatably connected to the fixed shaft 22, and an elastic strip 24 is fixedly installed on the adjustable clip 23. The end of the elastic strip 24 fits with the surface of the fixed shaft 22, and the flip plate 21 can be flipped around the outer stirring blade 6. By rotating the adjustable clip 23 around the fixed shaft 22, the adjustable clip 23 limits the flipping of the flip plate 21. At the same time, after the adjustable clip 23 rotates around the fixed shaft 22, the elastic strip 24 applies pressure to the fixed shaft 22 to fix the adjustable clip 23 after rotation, thereby ensuring the fixing effect of the adjustable clip 23 after rotation.

[0041] A rotatable ring 25 is provided on the outer movable sleeve of the driving rod 5, and a first locking bolt 2501 is threadedly connected to the rotatable ring 25, and the first locking bolt 2501 is supported at a corresponding position of the outer wall of the driving rod 5. A scraper plate 26 is fixedly installed on the rotatable ring 25, and the positions of the scraper plate 26 and the flip plate 21 correspond. A U-shaped buckle 27 is fixedly installed on the end of the scraper plate 26 away from the rotatable ring 25, and a telescopic plate 28 is movably installed on the U-shaped buckle 27, and a second locking bolt 2701 is threadedly connected to the U-shaped buckle 27, and the second locking bolt 2701 is supported at a corresponding position of the outer wall of the telescopic plate 28. The position of the scraper plate 26 is adjusted by rotating the rotatable ring 25 around the driving rod 5. The scraper plate 26 reaches the corresponding position of the notch on the annular baffle plate 2, and the telescopic plate 28 is telescoped in the U-shaped buckle 27, so that the telescopic plate 28 is engaged with the corresponding position of the notch on the annular baffle plate 2, so as to realize the fixation of the structure composed of the rotatable ring 25 and the scraper plate 26.

[0042] A sewage receiving trough 29 is fixedly installed at the connection position of the outer wall of the sedimentation tank 1 and the annular baffle plate 2, a sewage discharge pipe 30 is fixedly installed at the lowest point of the sewage receiving trough 29, a fixed assembly frame 31 is fixedly installed at the position corresponding to the highest point of the sewage receiving trough 29 on the outer wall of the annular baffle plate 2, an electric push rod 32 is fixedly installed on the top of the fixed assembly frame 31, a lifting baffle 33 is fixedly installed on the bottom end of the piston rod of the electric push rod 32, and the lifting baffle 33 is arranged at the corresponding position of the notch on the outer wall of the annular baffle plate 2. The sewage receiving trough 29 is used to receive impurities discharged from the surface of the notch position on the annular baffle plate 2, and the sewage discharge pipe 30 assists in the discharge of impurities. The lifting baffle 33 is driven to rise and fall by the piston rod of the electric push rod 32 to ensure the discharge of impurities on the surface of the sedimentation tank 1.

[0043] A cylinder 34 is fixedly mounted on the top of the outer stirring blade 6 , and a piston rod of the cylinder 34 is fixedly connected to the top of the inner stirring blade 7 .

[0044] Working principle: The first step: the wastewater produced by basic copper carbonate is injected into the sedimentation tank 1, and the piston rod of the cylinder 34 pushes the inner stirring blade 7 to rise and fall in the outer stirring blade 6. When the first guide groove 602 on the outer stirring blade 6 and the second guide groove 701 on the inner stirring blade 7 are misaligned, and the bottom of the inner stirring blade 7 is not in contact with the upper surface of the impurity precipitation plate 8, the piston rod of the first servo motor 4 drives the driving rod 5 to rotate. When the driving rod 5 rotates, it drives the structure composed of the outer stirring blade 6 and the inner stirring blade 7 to rotate, thereby achieving the mixing of the wastewater produced by basic copper carbonate and the medicine, ensuring the precipitation of impurities in the wastewater produced by basic copper carbonate. After the impurity precipitation is completed, the piston rod of the cylinder 34 pushes the inner stirring blade 7 down, so that the inner stirring blade 7 can contact the upper surface of the impurity precipitation plate 8, and then the outer stirring blade 6 and the inner stirring blade 7 are driven to rotate by the output shaft of the first servo motor 4. The outer stirring blade 6 When the inner stirring blade 7 rotates, the inner stirring blade 7 scrapes the sediment on the impurity sedimentation plate 8, and the impurities deposited on the surface of the impurity sedimentation plate 8 are scraped and moved by the second drainage groove 703 and scraped into the impurity gathering groove 801. At the same time, the first guide groove 602 on the outer stirring blade 6 corresponds to the second guide groove 701 on the inner stirring blade 7, reducing the resistance during the rotation of the outer stirring blade 6 and the inner stirring blade 7. At the same time, the first drainage groove 603 and the second drainage groove 703 can also have the same effect. The second servo motor 13 drives the driving wheel 11 to rotate through the connecting belt 14. When the driving wheel 11 rotates, it drives the transmission belt 12 to rotate, thereby driving the impurity pushing plate 9 to move in the impurity gathering groove 801. The impurity pushing plate 9 scrapes the impurities in the impurity gathering groove 801, and the impurities are discharged through the opening corresponding to the sealing plug 15 on the sedimentation tank 1 to achieve the discharge of impurities.

[0045] Step 2: The driving wheel 19 is driven to rotate by the third servo motor 18, and the driving wheel 19 rotates to drive the arc-shaped sealing plate 17 to move in the assembly buckle 16. When the arc-shaped sealing plate 17 moves, it is limited by the limiting plate 20, thereby ensuring the limiting effect of the movement of the arc-shaped sealing plate 17. When the arc-shaped sealing plate 17 moves to the specified position, the sealing plug 15 can be removed to ensure the discharge of impurities and prevent impurity leakage.

[0046] The third step: by rotating the rotatable ring 25 around the driving rod 5, the scraper plate 26 is made to correspond to the corresponding position of the notch on the annular baffle plate 2, and then the telescopic plate 28 is adjusted to engage the telescopic plate 28 with the notch on the annular baffle plate 2, and the telescopic plate 28 is fixed by rotating the second locking bolt 2701, and then the flip plate 21 is lifted upward, and the flip plate 21 is fixed after being lifted by rotating the adjustable clamping strip 23, and the flip plate 21 is driven to rotate by the rotation of the outer stirring blade 6, and the flip plate 21 scrapes up the impurities on the liquid surface of the sedimentation tank 1, and the impurities are forced by the flip plate 21 to reach between the scraper plate 26 and the flip plate 21, and the impurities flow out through the notch on the annular baffle plate 2, and the piston rod of the electric push rod 32 drives the lifting baffle 33 to lift and lower, and the impurities leave through the notch corresponding to the lifting baffle 33 on the annular baffle plate 2, and the impurities fall into the sewage receiving trough 29 and are discharged through the sewage discharge pipe 30.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
