Detailed Embodiment

[0019] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0020] Please combine Figures 1 to 4, A wastewater treatment device for kaolin processing in this embodiment includes a box body 1. Symmetrically installed at the bottom end of the box body 1 are support frames 2. At the top end of one side of the box body 1 is a water inlet 3. At the bottom end of the box body 1 and on the side close to the water inlet 3 is a sludge outlet 5. On one side of the box body 1 is a slot 6 located below the water inlet 3. The slot 6 is connected to the sludge outlet 5 and is located at the top of the sludge outlet 5. Inside the slot 6 is inserted a shielding plate 7. On the box body 1 is a locking member connected to the shielding plate 7. At the bottom end of the other side of the box body 1 is a water outlet 4. Inside the box body 1 is a moving cylinder 19. Inserted inside the moving cylinder 19 is a lifting plate 8. Installed at the bottom end of the lifting plate 8 is a sludge pushing plate 9. The outer wall of the sludge pushing plate 9 is in sliding contact with the side wall and the bottom end of the box body 1. At the top of the box body 1 is a moving mechanism connected to the moving cylinder 19. On both sides of the inner wall of the box body 1 are opened moving groove groups 18. Inside the moving cylinder 19 is a retracting and releasing mechanism connected to the lifting plate 8 and the moving groove groups 18. On one side of the box body 1 is an observation window 14 located between the water inlet 3 and the slot 6. The observation window 14 is made of transparent material, thus facilitating the observation of the wastewater liquid level inside the box body 1;

[0021] The staff injects the wastewater to be treated into the box body 1 through the water inlet 3, and then observes the liquid level inside the box body 1 through the observation window 14. When the liquid level is about to reach the bottom end of the moving cylinder 19, stop injecting wastewater into the box body 1. During the static process of the wastewater, solid-liquid sedimentation will occur. After sedimentation, open the water outlet 4 to make the wastewater drain through the water outlet 4. Then adjust the locking member to release the fixation of the shielding plate 7, and then pull the shielding plate 7 to disconnect the shielding of the sludge outlet 5 by the shielding plate 7. Then, through the moving mechanism, it is convenient to drive the moving cylinder 19, the lifting plate 8 and the sludge pushing plate 9 to move horizontally, facilitating the sludge pushing plate 9 to push the solids sedimented at the bottom end inside the box body 1 to move, so that the solids are discharged through the sludge outlet 5. During the movement of the sludge pushing plate 9, it will slide in the moving groove groups 18. After the solids are pushed out through the sludge outlet 5, there are residual accumulations inside the box body 1. Therefore, through the structural design of the moving groove groups 18 and the cooperation of the retracting and releasing mechanism, the sludge pushing plate 9 will rise, disconnecting the contact between the sludge pushing plate 9 and the bottom end of the box body 1. Then, in cooperation with the reverse movement of the moving mechanism, the reverse movement of the sludge pushing plate 9 is realized, thus facilitating the scraping of the bottom end of the box body 1 when the sludge pushing plate 9 approaches the sludge outlet 5, realizing the cleaning of the sediment inside the box body 1. When the sludge pushing plate 9 moves away from the sludge outlet 5, the sludge pushing plate 9 is suspended, effectively preventing the other side of the sludge pushing plate 9 from pushing the sediment at the bottom end of the box body 1 away from the sludge outlet 5, thus facilitating the full discharge of the sediment to the sludge outlet 5, effectively improving the cleaning quality and cleaning efficiency of the sediment inside the box body 1.

[0022] The moving mechanism includes a fixed seat 10 fixedly connected to the top end of the box body 1. A motor 13 is installed on one side of one of the fixed seats 10. A lead screw 11 rotatably connected to the two fixed seats 10 is installed on the output shaft of the motor 13. A threaded seat 12 connected to the top end of the moving cylinder 19 is sleeved on the lead screw 11, and the threaded seat 12 is threadedly connected to the lead screw 11;

[0023] By starting the motor 13, the motor 13 drives the lead screw 11 to rotate. Due to the threaded connection relationship between the lead screw 11 and the threaded seat 12 and the sliding connection relationship between the mud pushing plate 9 and the inner wall of the box body 1, the threaded seat 12 will move horizontally on the lead screw 11. Furthermore, the threaded seat 12 will drive the moving cylinder 19, the lifting plate 8 and the mud pushing plate 9 to move horizontally synchronously, which is convenient for the mud pushing plate 9 to push the sediment inside the box body 1 to be discharged through the mud outlet 5 when approaching the mud outlet 5. Then, by reversing the motor 13, the mud pushing plate 9 can be restored to its original position to perform the cleaning work on the sediment inside the box body 1 again.

[0024] The locking member includes a slot 15 opened at the bottom end of the shielding plate 7. A support block 16 fixedly connected to one side of the box body 1 and located below the shielding plate 7 is provided with a threaded rod 17 threadedly connected thereto, and one end of the threaded rod 17 extends into the slot 15. First, insert the shielding plate 7 into the slot 6 so that the shielding plate 7 shields the top end of the mud outlet 5. Then rotate the threaded rod 17. Due to the threaded connection relationship between the threaded rod 17 and the support block 16, one end of the threaded rod 17 can be inserted into the slot 15 at the bottom end of the shielding plate 7 to fix the shielding plate 7, thereby realizing the sealing of the mud outlet 5, which is convenient for the liquid in the wastewater to be discharged through the water outlet 4. After the liquid is discharged through the water outlet 4, rotate the threaded rod 17 in the reverse direction to make the threaded rod 17 disengage from the slot 15, disconnect the locking of the shielding plate 7, and then pull out the shielding plate 7 to disconnect the shielding of the mud outlet 5 by the shielding plate 7, which is convenient for the sediment inside the box body 1 to be discharged.

[0025] The moving slot group 18 includes a first slideway 26 opened on both sides of the inner wall of the box body 1 and a second slideway 27 located below it. The first slideway 26 and the second slideway 27 are arranged in parallel. The inner wall of the box body 1 is symmetrically provided with two third slideways 28 communicated with both ends of the first slideway 26 and the second slideway 27. The first slideway 26, the second slideway 27 and the two third slideways 28 form a parallelogram structure. The retracting and extending mechanism includes a first magnetic sheet 20 installed on the inner wall of the top end of the moving cylinder 19. A second magnetic sheet 29 is provided at the top end of the lifting plate 8. The first magnetic sheet 20 and the second magnetic sheet 29 have opposite magnetic polarities. Sliders 21 are symmetrically installed on both sides of the lifting plate 8. The inner wall of the moving cylinder 19 is symmetrically provided with chutes 22. The sliders 21 slide inside the chutes 22. The bottom ends of the sliders 21 are installed with springs 23 connected to the bottom ends of the chutes 22. Slide rods 24 are symmetrically and fixedly connected to the top ends of both sides of the lifting plate 8. Slide openings 25 are symmetrically opened on both sides of the moving cylinder 19. The slide rods 24 penetrate through the slide openings 25 and extend into the second slideway 27. It should be noted here that the slide rods 24 can slide inside the slide rods 24, the third slideways 28 and the first slideway 26. The suction force between the first magnetic sheet 20 and the second magnetic sheet 29 is greater than the elastic force of the spring 23, which is convenient for the slide rods 24 to slide into the first slideway 26 when the slide rods 24 move to the top ends of the third slideways 28 and move towards the water outlet 4;

[0026] After the mud outlet 5 is opened, start the forward rotation of the motor 13. The threaded seat 12 will drive the moving cylinder 19, the lifting plate 8 and the mud pushing plate 9 to approach the mud outlet 5, and the sliding rod 24 will slide inside the second slideway 27, facilitating the scraping of the bottom end of the inner wall of the box body 1 by the mud pushing plate 9. The mud pushing plate 9 will push the sediment to be discharged through the mud outlet 5. During the process of the mud pushing plate 9 approaching the mud outlet 5, sediment will accumulate on one side, and then some sediment will fall to the other side of the mud pushing plate 9. When the sliding rod 24 moves to the bottom end of the third slideway 28, due to the inclined design of the third slideway 28, as the moving cylinder 19 continues to move horizontally, the sliding rod 24 will slide in the third slideway 28, causing the lifting plate 8 to drive the mud pushing plate 9 to move upward, realizing the suspension of the mud pushing plate 9, enabling the slider 21 to slide in the chute 22, and stretching the spring 23. At the same time, the second magnetic piece 29 will approach the first magnetic piece 20. When the sliding rod 24 moves to the top end of the third slideway 28, the first magnetic piece 20 will be adsorbed and connected to the second magnetic piece 29. At this time, the moving cylinder 19 moves to contact the side wall of the box body 1, causing the mud pushing plate 9 to disengage from the bottom end of the box body 1. Then start the reverse rotation of the motor 13, which will cause the moving cylinder 19 to move in the reverse direction. Since the magnetic force between the first magnetic piece 20 and the second magnetic piece 29 is greater than the elastic force of the spring 23, the sliding rod 24 will slide into the first slideway 26, facilitating the mud pushing plate 9 to always maintain a non-contact relationship with the bottom end of the inner wall of the box body 1 during the process of approaching the water outlet 4. Thus, it can be avoided that the mud pushing plate 9 pushes the sediment at the bottom of the box body 1 away from the mud outlet 5. When the sliding rod 24 moves to one end of the first slideway 26, as the moving cylinder 19 continues to move, the sliding rod 24 will slide into another third slideway 28, and due to the inclined design of the third slideway 28, the sliding rod 24 will drive the lifting plate 8 to move downward, disconnecting the adsorption connection relationship between the first magnetic piece 20 and the second magnetic piece 29, and causing the lifting plate 8 to drive the mud pushing plate 9 to move downward. When the sliding rod 24 moves to the bottom end of the first slideway 26, the moving cylinder 19 will contact the side wall of the mud outlet 5, causing the mud pushing plate 9 to closely contact the bottom end of the inner wall of the box body 1 again, facilitating the mud pushing plate 9 to push the remaining sediment inside the box body 1 to be discharged through the mud outlet 5 again. Therefore, this design effectively improves the cleaning quality and cleaning efficiency of the sediment.

[0027] The implementation principle of a wastewater treatment device for kaolin processing in the embodiment of this application is as follows:

[0028] First, insert the baffle plate 7 into the slot 6 so that the baffle plate 7 blocks the top of the mud outlet 5. Then, rotate the threaded rod 17. Due to the threaded connection between the threaded rod 17 and the support block 16, one end of the threaded rod 17 is inserted into the slot 15 at the bottom end of the baffle plate 7 to fix the baffle plate 7, thereby achieving the sealing of the mud outlet 5. Next, the staff injects the wastewater to be treated into the box body 1 through the water inlet 3 and observes the liquid level inside the box body 1 through the observation window 14. When the liquid level is about to reach the bottom end of the moving cylinder 19, stop injecting wastewater into the box body 1. During the static process of the wastewater, solid-liquid sedimentation will occur. After sedimentation, open the water outlet 4 to discharge the wastewater through the water outlet 4. When the liquid is discharged through the water outlet 4, rotate the threaded rod 17 in the reverse direction to make the threaded rod 17 disengage from the slot 15, unlock the baffle plate 7, and then pull out the baffle plate 7 to disconnect the baffle of the baffle plate 7 from the mud outlet 5, which facilitates the discharge of the sediment inside the box body 1;

[0029] Next, start the forward rotation of the motor 13. The motor 13 drives the screw rod 11 to rotate. Due to the threaded connection relationship between the screw rod 11 and the threaded seat 12 and the sliding connection relationship between the mud pushing plate 9 and the inner wall of the box body 1, the threaded seat 12 will move horizontally on the screw rod 11. Furthermore, the threaded seat 12 will drive the moving cylinder 19, the lifting plate 8, and the mud pushing plate 9 to move horizontally synchronously and approach the mud outlet 5, causing the sliding rod 24 to slide inside the second slideway 27, facilitating the scraping of the bottom end of the inner wall of the box body 1 by the mud pushing plate 9. The mud pushing plate 9 pushes the sediment to be discharged through the mud outlet 5. When the sliding rod 24 moves to the bottom end of the third slideway 28, due to the inclined design of the third slideway 28, as the moving cylinder 19 continues to move horizontally, the sliding rod 24 will slide in the third slideway 28, causing the lifting plate 8 to drive the mud pushing plate 9 to move upward, realizing the suspension of the mud pushing plate 9, causing the slider 21 to slide in the chute 22, and stretching the spring 23. At the same time, the second magnetic sheet 29 approaches the first magnetic sheet 20. When the sliding rod 24 moves to the top end of the third slideway 28, the first magnetic sheet 20 will be adsorbed and connected to the second magnetic sheet 29. At this time, the moving cylinder 19 moves to contact the side wall of the box body 1, causing the mud pushing plate 9 to be separated from the bottom end of the box body 1. Then start the reverse rotation of the motor 13, which will cause the moving cylinder 19 to move in the reverse direction. Since the magnetic force between the first magnetic sheet 20 and the second magnetic sheet 29 is greater than the elastic force of the spring 23, the sliding rod 24 will slide into the first slideway 26, facilitating the mud pushing plate 9 to always maintain a separated contact relationship with the bottom end of the inner wall of the box body 1 during the process of approaching the water outlet 4. Furthermore, it can prevent the mud pushing plate 9 from pushing the sediment at the bottom of the box body 1 away from the mud outlet 5. When the sliding rod 24 moves to one end of the first slideway 26, as the moving cylinder 19 continues to move, the sliding rod 24 will slide into another third slideway 28, and due to the inclined design of the third slideway 28, the sliding rod 24 will drive the lifting plate 8 to move downward, causing the first magnetic sheet 20 to be disconnected from the adsorbed connection relationship with the second magnetic sheet 29, and causing the lifting plate 8 to drive the mud pushing plate 9 to move downward. When the sliding rod 24 moves to the bottom end of the first slideway 26, the moving cylinder 19 will contact the side wall of the mud outlet 5, causing the mud pushing plate 9 to closely contact the bottom end of the inner wall of the box body 1 again, facilitating the mud pushing plate 9 to push the remaining sediment inside the box body 1 to the mud outlet 5 for discharge again. Therefore, this design effectively improves the cleaning quality and cleaning efficiency of the sediment.
