[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an anti-sedimentation stirrer for a centrifugal mother liquor buffer tank, comprising a tank body 1, a fixing block 2 disposed above the tank body 1, a motor 19 disposed above the fixing block 2, the output end of the motor 19 being connected to a lead screw 3, the lead screw 3 being disposed inside the fixing block 2, the front end of the lead screw 3 being fixedly connected to a rotating rod 4, the upper part of the lead screw 3 being threadedly connected to a slider 5, and the slider 5 being slidably connected to the inside of the fixing block 2, a spline sleeve 6 disposed on the tank body 1, and a spline shaft 7 disposed on the spline sleeve 6 for cooperation, a connecting plate 8 disposed on the upper end of the spline shaft 7, one end of the connecting plate 8 being connected to the slider 5, and the spline sleeve 6 being fitted with... One end of the pulley 9 is connected to the transmission belt 10, and the other end of the transmission belt 10 is connected to the pulley 9 and the rotating rod 4. A stirring rod 11 is provided below the spline shaft 7. Multiple mixing rods 12 are provided on the stirring rod 11. The stirring rod 11 and the mixing rod 12 are connected in the middle. Multiple scrapers 13 are provided on the mixing rod 12. The upper part of the mixing rod 12 is slidably connected to the scraper 13. The mixing rod 12 is fixed to the scraper 13 by bolts. The surface of the mixing rod 12 is provided with air vents 14. Multiple stirring blades 15 are provided on the stirring rod 11. The stirring blades 15 have different inclination angles. The connecting plate 8 is connected to the slider 5 by bolts.

[0019] During operation, after the centrifuged mother liquor enters the tank 1, the motor 19 drives the lead screw 3 to rotate. Simultaneously, the lead screw 3 drives the rotating rod 4 below to rotate. At this time, the lead screw 3 moves the slider 5, causing the slider 5 to adjust the height of the connecting plate 8. Simultaneously, the connecting plate 8 causes the spline shaft 7 to slide inside the spline sleeve 6, allowing the stirring rod 11, mixing rod 12, and stirring blade 15 to adjust their height within the tank 1. Meanwhile, the rotating rod 4, in conjunction with the pulley 9, drives the transmission belt 10 to rotate, which in turn drives the spline sleeve 6 to rotate. At the same time, the spline sleeve 6 drives the spline shaft 7 to rotate, and the spline shaft 7 drives the stirring rod 11 to rotate, causing the mixing rod 12 and stirring blade 15 on the surface to rotate, stirring the centrifuged mother liquor inside to prevent sedimentation. Meanwhile, the scraper 13 on the surface of the mixing rod 12 scrapes inside the tank 1 to prevent sticking to the inner wall. As the lead screw 3 continuously drives the slider 5 to move up and down and rotate in opposite directions, the stirring rod 11, mixing rod 12 and stirring blade 15 inside the tank continuously rotate, which can stir different liquid layers inside the tank 1 to prevent sedimentation.

[0020] The tank body 1 is equipped with an air supply assembly 16, which includes a connector 161, a fixed pipe 162, an air supply hose 163, and a connecting pipe 164. The connecting pipe 164 is installed on the tank body 1. The lower end of the connecting pipe 164 is connected to an external air supply pump, and the upper end of the connecting pipe 164 is connected to the air supply hose 163. The upper part of the air supply hose 163 is connected to the fixed pipe 162. The fixed pipe 162 is connected to the stirring rod 11 through the connector 161. The upper end of the fixed pipe 162 is rotatably connected to the lower end of the stirring rod 11. The connector 161 is equipped with a sealing bearing 17, which is connected to the surface of the stirring rod 11. The connector 161 is equipped with two sets of sealing gaskets 18, which are in contact with the surfaces of the fixed pipe 162 and the stirring rod 11, respectively.

[0021] During the mixing process, after the external air pump fills the connecting pipe 164 with air, the gas enters the mixing rod 11 through the air supply hose 163 and the connector 161, and then enters the mixing rod 12. The gas is then ejected through multiple air outlets 14 inside the mixing rod 12 to improve the mixing effect. When the height of the mixing rod 11 is adjusted, the lower air supply hose 163 is stretched. When the mixing rod 11 rotates, the lower end of the mixing rod 11 rotates inside the connector 161 and on the fixed pipe 162 in conjunction with the sealing bearing 17. At the same time, the sealing gaskets 18 at both ends of the connector 161 can maintain a seal to prevent liquid from entering.

[0022] Working Principle: When using the anti-sedimentation stirrer in the centrifugal mother liquor buffer tank, after the centrifugal mother liquor enters the tank body 1, the motor 19 drives the lead screw 3 to rotate. Simultaneously, the lead screw 3 drives the rotating rod 4 below to rotate. At this time, the lead screw 3 drives the slider 5 to move, causing the slider 5 to adjust the height of the connecting plate 8. Simultaneously, the connecting plate 8 drives the spline shaft 7 to slide inside the spline sleeve 6, allowing the stirring rod 11, mixing rod 12, and stirring blade 15 to adjust their height inside the tank body 1. Meanwhile, the rotating rod 4, in conjunction with the pulley 9, drives the transmission belt 10 to rotate. The transmission belt 10 drives the spline sleeve 6 to rotate, which in turn drives the spline shaft 7 to rotate. The spline shaft 7 then drives the stirring rod 11 to rotate, causing the mixing rod 12 and stirring blade 15 on the surface to rotate, stirring the centrifugal mother liquor inside and preventing sedimentation. At the same time, the scraper 13 on the surface of the mixing rod 12 scrapes inside the tank body 1 to prevent sticking to the inner wall. As the lead screw 3 continuously drives the slider 5 to move up and down in opposite directions, the internal stirring rod 11, mixing rod 12, and stirring blade 15 rotate continuously, which can stir different liquid layers inside the tank 1 and prevent sedimentation. During the stirring process, after the external air supply pump fills the connecting pipe 164 with air, the gas enters the stirring rod 11 through the air supply hose 163 and the connector 161, then enters the mixing rod 12, and is ejected through multiple air outlets 14 inside the mixing rod 12 to improve the stirring effect. When the height of the stirring rod 11 is adjusted, the lower air supply hose 163 is stretched. When the stirring rod 11 rotates, the lower end of the stirring rod 11 rotates in conjunction with the sealing bearing 17 inside the connector 161 and on the fixed pipe 162. At the same time, the sealing gaskets 18 at both ends of the connector 161 can keep sealed to prevent liquid from entering, thus completing a series of operations. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
