Description

Technical Field

[0002] The slurry silicon stirring separation kettle is a kind of equipment used in industrial production. It is mainly used to separate solids and liquids in slurries. This equipment is widely used in many industries, including biology, medicine, food, coatings, inks, adhesives, cosmetics, dyes, etc. It can handle various dispersing and stirring operations of liquid-liquid (miscible, dispersed), solid-liquid, gas-liquid or several combinations.

[0003] Chinese invention patent CN117443224A discloses a slurry agitator, comprising a frame, a reducer arranged on the top of the frame, a motor arranged on the reducer, a vertical stirring shaft whose upper end is penetrated and fixedly connected with the output shaft of the reducer, a hub fixedly arranged at the lower end of the stirring shaft and blades arranged on the hub, wherein a rotating arm is rotatably connected to the hub; an end plate is arranged below the hub, and a connecting rod is arranged between the end plate and the rotating arm; the slurry agitator has low stirring efficiency and poor stirring effect.

[0004] Chinese invention patent CN118341320A relates to a slurry stirring device, which belongs to the technical field of stirring devices. It includes a barrel and a motor. The motor is arranged above the barrel and connected to the barrel. The output shaft of the motor is fixedly connected to a rotating rod. The end of the rotating rod away from the motor extends into the barrel. A plurality of stirring blades are arranged. The plurality of stirring blades are evenly distributed on the circumferential side wall of the rotating rod. A rotating plate is arranged inside the upper end of the barrel. The slurry stirring device is difficult to operate, and the stirring and separation of the slurry is difficult.

[0005] When the slurry silicon inside the stirring tank is stirred and separated, a large amount of slurry silicon will accumulate at the bottom of the stirring tank, and the slurry silicon cannot be stirred and separated thoroughly and effectively, thereby reducing the stirring and separation efficiency of the slurry silicon.

[0006] Furthermore, when the drum screen is used for long-term screening of slurry silicon, the sieve holes inside the drum screen are easily clogged by the slurry silicon, and the slurry silicon is easily attached to the inner wall of the drum screen, thereby reducing the stirring and separation effect of the slurry silicon.

[0007] However, the finished liquid after screening tends to accumulate on one side of the finished product pipe. The finished liquid with its own viscosity cannot be discharged quickly and efficiently along the finished product pipe only by its own gravity and flow force, thereby reducing the recovery efficiency of the finished liquid.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1-9As shown, the slurry silicon stirring and separation kettle comprises a stirring kettle 1, a separation chamber 2 is arranged inside the stirring kettle 1, the slurry silicon is stirred and separated inside the separation chamber 2 to obtain a finished product liquid, a finished product pipe 9 is opened at the lower side of the stirring kettle 1, the finished product liquid that meets the requirements in the separation chamber 2 is discharged along the finished product pipe 9, a flow sensor 31 is arranged inside the finished product pipe 9, and the flow sensor 31 is used to detect the flow value of the finished product liquid discharged from the finished product pipe 9.

[0043] Among them, a control panel 6 is provided on one side of the stirring kettle 1, and the control panel 6 electrically controls each electrical component. A liquid inlet pipe 7 is connected to one side of the stirring kettle 1, and the output end of the liquid inlet pipe 7 is connected to the interior of the separation chamber 2. Slurry silicon is introduced into the separation chamber 2 along the liquid inlet pipe 7. An anti-overflow pipe 8 is connected to the other side of the stirring kettle 1. The height values ​​of the liquid inlet pipe 7 and the anti-overflow pipe 8 are both greater than the height value of the drum screen 18. The input end of the anti-overflow pipe 8 is connected to the interior of the separation chamber 2. When the amount of slurry silicon in the separation chamber 2 is too large and greater than the height of the anti-overflow pipe 8, the slurry silicon is discharged along the anti-overflow pipe 8. The setting of the anti-overflow pipe 8 avoids the loss of slurry silicon caused by excessive amount of slurry silicon in the separation chamber 2.

[0044] The bottom of the stirring kettle 1 is connected with a drainage pipe 10, and the top of the drainage pipe 10 is connected with the inner bottom of the separation chamber 2. A solenoid valve 11 is arranged inside the drainage pipe 10. When the slurry silicon separation is completed, the solenoid valve 11 is opened, and the impurities inside the separation chamber 2 are discharged downward along the drainage pipe 10. An observation window 12 is arranged on one side of the stirring kettle 1. The arrangement of the observation window 12 facilitates timely observation of the separation of the slurry silicon inside the separation chamber 2. A cleaning brush 13 is arranged inside the observation window 12. The inner wall of the observation window 12 can be cleaned by rotating the cleaning brush 13, thereby improving the observation effect of the observation window 12. An air inlet pipe is arranged on one side of the stirring kettle 1 14, the output end of the air inlet pipe 14 is connected with the interior of the separation chamber 2, and an exhaust pipe 15 is provided on the other side of the stirring kettle 1, and the input end of the exhaust pipe 15 is connected with the interior of the separation chamber 2. Before the slurry silicon is introduced into the separation chamber 2 along the liquid inlet pipe 7, the air inlet pipe 14 and the exhaust pipe 15 are both opened, and a protective gas, such as nitrogen, is introduced into the air inlet pipe 14 at the same time. The gas can squeeze the air inside the separation chamber 2 and discharge it along the exhaust pipe 15, so that the interior of the separation chamber 2 is filled with protective gas, thereby avoiding air contamination during the subsequent stirring and separation of the slurry silicon, thereby improving the cleanliness and safety of the stirring and separation.

[0045] A drum screen 18 is movably connected inside the separation chamber 2. A plurality of sieve holes 19 are evenly arranged inside the drum screen 18. The diameter of the sieve holes 19 can reach 2000 meshes, so that the slurry silicon inside the drum screen 18 is screened with the help of the sieve holes 19 and a finished liquid of a required diameter is obtained. A driving shaft 20 is rotatably connected inside the drum screen 18. A threaded rod 21 is arranged at the bottom of the driving shaft 20. The driving shaft 20 rotates and drives the threaded rod 21 to rotate. A sleeve 22 is slidably connected to the outer surface of the driving shaft 20. A plurality of grooves are evenly arranged on the outer surface of the driving shaft 20. A block is arranged on the inner wall of the sleeve 22. The grooves and the block are engaged with each other. The driving shaft 20 rotates and drives the sleeve 22 to rotate through the engagement between the grooves and the block. A side hole 23 is opened inside the lower part of the sleeve 22. A threaded cylinder 24 is rotatably connected inside the side hole 23. A plurality of stirring plates 27 are movably connected to the outer surface of the sleeve 22. The sleeve 22 rotates and drives the plurality of stirring plates 27 to rotate, so as to stir and separate the slurry silicon inside the drum screen 18.

[0046] A limiting ring groove 39 is provided at the inner top of the side hole 23, and a friction ring block 40 is provided at the top of the threaded barrel 24. The limiting ring groove 39 is sealed and slidably connected with the friction ring block 40, so that the friction ring block 40 can slide inside the limiting ring groove 39. Due to the friction between the friction ring block 40 and the limiting ring groove 39, the outer surface of the threaded rod 21 is sealed and threadedly connected with the inner wall of the threaded barrel 24. In the initial case, since the threaded rod 21 and the threaded barrel 24 are in the same position, the threaded rod 21 and the threaded barrel 24 rotate at the same rate, and the threaded rod 21 and the threaded barrel 24 do not rotate relative to each other. An electric push rod 30 is provided at the bottom of the threaded rod 21, and the bottom of the electric push rod 30 is fixedly connected to the inner bottom of the sleeve 22. Therefore, when the electric push rod 30 is started and the output end is extended, the electric push rod 30 drives the sleeve 22 to move downward, and the sleeve 22 drives the threaded barrel 24 to move downward, and the position of the threaded barrel 24 and the threaded rod 21 changes. In this case, the threaded barrel 24 rotates relative to the threaded rod 21.

[0047] A top shell 3 is provided on the top of the stirring tank 1, a coupling 4 is provided inside the top shell 3, a driving motor 5 is provided on the top of the top shell 3, the bottom output end of the driving motor 5 is connected to the top input end of the coupling 4, the bottom output end of the coupling 4 passes through the stirring tank 1 and is fixedly connected to the top of the driving shaft 20, then the driving motor 5 is started and drives the driving shaft 20 to rotate through the coupling 4.

[0048] Two elastic connecting rings 16 are symmetrically provided on the upper and lower inner walls of the separation chamber 2. The elastic connecting rings 16 are elastic and can undergo elastic deformation. A splicing ring 17 is provided on the inner wall of the elastic connecting ring 16. The inner wall of the splicing ring 17 is fixedly connected to the upper and lower outer surfaces of the drum screen 18. The splicing ring 17 connects the elastic connecting ring 16 and the drum screen 18, so that the drum screen 18 can squeeze the elastic connecting ring 16 and change its position. A plurality of reset springs 38 are evenly provided on the inner wall of the separation chamber 2 and close to the side of the baffle rod 37. The other end of the reset spring 38 is fixedly connected to the side wall of the drum screen 18. The setting of the reset spring 38 improves the elastic reset performance of the drum screen 18.

[0049] A plurality of first connecting plates 25 are rotatably connected to the outer surface of the sleeve 22 through a movable seat 41, and the position of the first connecting plate 25 on the outer surface of the sleeve 22 will not change. The outer surface of the threaded cylinder 24 is rotatably connected to the second connecting plate 26 through the movable seat 41, and the position of the second connecting plate 26 will change accordingly with the position of the threaded cylinder 24. The side walls of the first connecting plate 25 and the second connecting plate 26 are fixedly connected to the side walls of the same stirring plate 27, and the lengths of the first connecting plate 25 and the second connecting plate 26 are equal. Therefore, when the positions of the first connecting plate 25 and the second connecting plate 26 do not change, the stirring plate 27 is in a vertical state, and the sleeve 22 rotates through the first connecting plate The connecting plate 25 and the second connecting plate 26 drive the stirring plate 27 to rotate synchronously, thereby stirring and separating the slurry silicon inside the drum screen 18. When the threaded cylinder 24 drives the second connecting plate 26 to rotate in the rotation direction, the position of the second connecting plate 26 changes, and the second connecting plate 26 drives the stirring plate 27 to move downward in the rotation direction. The stirring plate 27 tilts, and the tilting direction matches the rotation direction. The distance between the top of the stirring plate 27 and the inner wall of the drum screen 18 decreases synchronously. As the stirring plate 27 forms a spiral structure and rotates, the slurry silicon at the bottom of the separation chamber 2 is lifted upward and stirred and separated, thereby further improving the separation efficiency and separation effect of the slurry silicon.

[0050] A plurality of elastic cleaning plates 29 are evenly provided at one end of the stirring plate 27 away from the sleeve 22. The elastic cleaning plates 29 are in elastic extrusion contact with the inner wall of the drum screen 18, further improving the rotational cleaning effect of the stirring plate 27 on the sieve holes 19 inside the drum screen 18. A plurality of reflux holes 28 are evenly provided inside the stirring plate 27. As the stirring plate 27 rotates continuously, the slurry silicon inside the drum screen 18 continuously shuttles back along the reflux holes 28, further improving the stirring effect on the slurry silicon inside the drum screen 18, and correspondingly improving the subsequent separation efficiency of the slurry silicon.

[0051] A baffle 37 is provided on the inner wall of the drum screen 18 and on the side close to the finished product pipe 9, and the baffle 37 matches the stirring plate 27, so when the stirring plate 27 rotates continuously, it will be squeezed and collided with the baffle 37, and the baffle 37 drives the drum screen 18 to squeeze the elastic connecting ring 16 through the splicing ring 17 to elastically move toward the end close to the finished product pipe 9. A one-way drain valve 32 is provided inside the finished product pipe 9, and the drainage direction of the one-way drain valve 32 is along the inside of the connecting cylinder 33 to the inside of the finished product pipe 9. The side of the finished product pipe 9 close to the drum screen 18 is connected to the end of the drum screen 18. There is a connecting cylinder 33, the bottom of which matches the top of the elastic connecting ring 16, and a pressure bellows 36 is provided on the other side of the connecting cylinder 33. The end of the pressure bellows 36 away from the connecting cylinder 33 is sealed and fixedly connected to the outer wall of the drum screen 18. The pressure bellows 36 is elastic. When the drum screen 18 moves toward the end of the finished product pipe 9, it squeezes the pressure bellows 36. The internal pressure of the pressure bellows 36 increases and discharges the finished liquid inside the connecting cylinder 33 along the one-way drain valve 32 to the inside of the finished product pipe 9 for discharge.

[0052] A plurality of drainage holes 34 are evenly arranged inside the connecting cylinder 33, and a one-way liquid inlet valve 35 is arranged inside the drainage hole 34. The liquid inlet direction of the one-way liquid inlet valve 35 is from the end 2 of the separation chamber to the end of the connecting cylinder 33. Similarly, when the extrusion pressure on the inner wall of the drum screen 18 disappears, the drum screen 18 is driven to move in the opposite direction to return to its original position under the elastic force of the reset spring 38 and the elastic connecting ring 16, and then the extrusion pressure of the drum screen 18 on the pressure bellows 36 disappears, and the pressure bellows 36 returns to its original state under the action of its own elastic force, and the internal pressure of the pressure bellows 36 is reduced. Under the action of negative pressure, the finished liquid that has been screened by the sieve holes 19 inside the drum screen 18 is drawn into the connecting cylinder 33 along the one-way liquid inlet valve 35 and waits for subsequent discharge. As the drum screen 18 continues to move elastically, the discharge efficiency and discharge effect of the finished liquid are further improved, thereby avoiding that part of the finished liquid cannot be discharged and causes waste.

[0053] When the slurry silicon inside the separation chamber 2 is stirred and separated, if a large amount of slurry silicon accumulates at the bottom of the separation chamber 2, the slurry silicon cannot be thoroughly and effectively stirred and separated, thereby reducing the stirring and separation efficiency of the slurry silicon; and when used for a long time, the sieve holes 19 inside the drum screen 18 are easily blocked by the slurry silicon, and the inner wall of the drum screen 18 is also easily attached with some slurry silicon, and the elastic cleaning plate 29 cannot clear and separate the slurry silicon blocked inside the sieve holes 19 when rotating at the same position with the stirring plate 27 for a long time, thereby reducing the stirring and separation effect of the slurry silicon; and the finished liquid after screening accumulates on one side of the finished product pipe 9, and the finished liquid with its own viscosity cannot be discharged quickly and efficiently along the finished product pipe 9 by its own gravity and flow force, thereby reducing the recovery efficiency of the finished liquid.

[0054] In order to solve the above problems, when the slurry silicon stirring separation kettle is actually used, the control panel 6 is firstly used to open the air inlet pipe 14 and the exhaust pipe 15, and the stable gas is continuously introduced into the air inlet pipe 14, and the stable gas enters the separation chamber 2 along the air inlet pipe 14, and the air inside the separation chamber 2 is discharged along the exhaust pipe 15, thereby improving the cleaning effect inside the separation chamber 2, and then the liquid inlet pipe 7 is opened and the slurry silicon is introduced into the liquid inlet pipe 7, and the slurry silicon continuously enters the separation chamber 2 and waits for subsequent stirring and separation. After the slurry silicon inside the separation chamber 2 reaches a suitable height, Slurry silicon is no longer introduced into the liquid inlet pipe 7, and when the amount of slurry silicon in the separation chamber 2 reaches the height of the anti-overflow pipe 8, the excess slurry silicon is discharged along the anti-overflow pipe 8 and recovered, so as to avoid excessive amount of slurry silicon in the separation chamber 2 and reduce the subsequent stirring and separation effect. In this process, the amount of slurry silicon in the separation chamber 2 and the subsequent stirring and separation effect can be observed in real time through the observation window 12, so as to ensure the stirring and separation effect of the slurry silicon, and when the inner wall of the observation window 12 is blocked, the cleaning brush 13 is rotated to clean it, so as to improve the subsequent observation effect.

[0055] Then the control panel 6 starts the drive motor 5, and the drive motor 5 drives the drive shaft 20 to rotate clockwise through the coupling 4, and the drive shaft 20 drives the threaded rod 21 at the bottom and the electric push rod 30 to rotate clockwise synchronously, and the drive shaft 20 drives the sleeve 22 to rotate clockwise through the cooperation of the card slot and the card block, and the sleeve 22 drives the threaded barrel 24 to rotate clockwise through the friction force of the limit ring groove 39 and the friction ring block 40. At this time, since the position of the sleeve 22 does not change, the rotation speed of the threaded barrel 24 and the threaded rod 21 is the same, and the position of the threaded barrel 24 does not change. The first connecting plate 25 and the second connecting plate 26 are in the same position, and the stirring plate 27 is in a vertical state. When the sleeve 22 rotates, the multiple stirring plates 27 on the surrounding side surfaces are synchronously driven to rotate clockwise. The stirring plates 27 stir and separate the slurry silicon inside the drum screen 18, and the finished liquid with a size smaller than the size of the sieve holes 19 is discharged through the sieve holes 19 inside the drum screen 18 and reaches the outside of the drum screen 18, and the area is divided by the elastic connecting ring 16, the splicing ring 17, the inner wall of the separation chamber 2 and the outer wall of the drum screen 18. The area carries the finished liquid and waits for subsequent discharge.

[0056] As the stirring plate 27 continues to rotate, the stirring plate 27 drives the elastic cleaning plate 29 to rotate continuously and scrape and clean the inner wall of the drum screen 18, further improving the dredging and screening properties of the drum screen 18, and the slurry silicon inside the drum screen 18 continuously shuttles back along the reflux hole 28, thereby improving the stirring and separation effect of the slurry silicon inside the drum screen 18, avoiding the slurry silicon from accumulating in one place for a long time and sticking to the inner wall of the drum screen 18.

[0057] At the same time, when the stirring plate 27 drives the elastic cleaning plate 29 to rotate and comes into contact with the baffle rod 37, the baffle rod 37 moves away from the end of the sleeve 22 under the extrusion force of the stirring plate 27 and the elastic cleaning plate 29, and the baffle rod 37 synchronously drives the drum screen 18 to move closer to the end of the finished pipe 9 by squeezing the elastic connecting ring 16 and multiple reset springs 38 through the splicing ring 17. The drum screen 18 and the drive shaft 20 are in different axial positions. At this time, when the sleeve 22 drives the stirring plate 27 to rotate through the first connecting plate 25 and the second connecting plate 26, the inside of the drum screen 18 can be stirred and separated on different axes to achieve stirring instability and improve the stirring and separation effect.

[0058] When the drum screen 18 moves toward the end of the finished product pipe 9, the drum screen 18 correspondingly squeezes the pressure bellows 36. The pressure bellows 36 is squeezed and elastically contracts, then the internal volume of the pressure bellows 36 decreases and the pressure increases. With the help of the pressure action of the pressure bellows 36, the finished liquid in the connecting cylinder 33 is discharged along the one-way drain valve 32 to the finished product pipe 9. The flow value detected by the flow sensor 31 reaches the set flow preset value, and the finished liquid in the finished product pipe 9 is continuously discharged and recovered, so that the required finished liquid is obtained quickly and efficiently, ensuring the recovery efficiency and recovery effect of the finished liquid.

[0059] However, when the stirring plate 27 and the elastic cleaning plate 29 are separated from the baffle 37, the elastic connecting ring 16 and multiple reset springs 38 drive the drum screen 18 to move in the opposite direction and return to its original position, and the drum screen 18 returns to the coaxial position with the drive shaft 20, and the distance between the drum screen 18 and the finished product pipe 9 increases and returns to the initial value. At this time, the drum screen 18 continuously vibrates left and right inside the separation chamber 2, and the slurry silicon inside the drum screen 18 can be separated by the vibration of the drum screen 18 in the left and right directions, and cooperate with multiple stirring plates 27 to drive the elastic cleaning plate 29 to rotate and rotate and stir the slurry silicon inside the drum screen 18 for separation, thereby improving the clearing effect of the sieve holes 19 inside the drum screen 18, and further improving the stirring and separation effect of the slurry silicon inside the drum screen 18.

[0060] When the drum screen 18 moves away from the end of the finished product pipe 9, the squeezing pressure of the drum screen 18 on the pressure bellows 36 decreases, and the pressure bellows 36 returns to its original state under the elastic force of the pressure bellows 36. In this process, the internal volume of the pressure bellows 36 increases and the pressure decreases. Under the action of negative pressure, the finished liquid on the outside of the drum screen 18 is continuously gathered to the inside of the connecting tube 33 along the one-way liquid inlet valve 35 inside the discharge hole 34 to wait for subsequent discharge along the finished product pipe 9. The finished liquid on the outside of the drum screen 18 can be continuously gathered to the inside of the connecting tube 33, avoiding the finished liquid from being unable to be quickly discharged along the finished product pipe 9 only by its own gravity and flow force, and avoiding the finished liquid from accumulating and adhering to the inside of the separation chamber 2 under the action of its own viscosity and reducing the discharge efficiency, thereby improving the discharge efficiency and ensuring the discharge effect.

[0061] As the finished liquid is continuously discharged, the flow value detected by the flow sensor 31 is the set flow preset value. When the flow value detected by the flow sensor 31 is less than the set flow preset value, it means that the amount of finished liquid discharged along the finished product pipe 9 is reduced. Then the control panel 6 controls the electric push rod 30 to start and the output end is extended. The electric push rod 30 drives the sleeve 22 to move downward along the outer surface of the drive shaft 20, and the sleeve 22 drives the threaded cylinder 24 to move downward. At this time, since the height of the threaded cylinder 24 relative to the threaded rod 21 changes, the threaded cylinder 24 rotates clockwise relative to the threaded rod 21 by a certain angle, and the rotation direction is the same as the rotation direction of the drive shaft 20, both of which are clockwise. The threaded cylinder 24 drives the second connecting plate 26 to rotate clockwise by a certain angle through the movable seat 41, and since the sleeve 22 drives the first connecting plate 25 and the second connecting plate 26 to rotate clockwise by a certain angle, the threaded cylinder 24 rotates clockwise by a certain angle. The connecting plate 26 moves downward synchronously, so the height of the first connecting plate 25 and the second connecting plate 26 does not change, but the relative angle of the first connecting plate 25 and the second connecting plate 26 changes, and the second connecting plate 26 synchronously drives the bottom of the stirring plate 27 to rotate clockwise by a certain angle. In this process, the stirring plate 27 is tilted, and the tilting direction matches the rotation direction. When the driving shaft 20 rotates and drives the sleeve 22 to rotate clockwise, the sleeve 22 drives the stirring plate 27 to rotate clockwise through the first connecting plate 25 and the second connecting plate 26. At this time, the stirring plate 27 uses its own tilted state to make it spirally rotate, and then the slurry silicon located at the bottom of the separation chamber 2 is spirally lifted upward, further improving the thoroughness of the stirring and separation of the slurry silicon inside the separation chamber 2, and avoiding the accumulation of part of the slurry silicon at the bottom of the separation chamber 2 and reducing the separation rate.

[0062] At the same time, due to the inclination of the stirring plate 27, the distance between the upper side wall of the stirring plate 27 and the outer wall of the sleeve 22 increases. As the sleeve 22 rotates, the stirring plate 27 drives the elastic cleaning plate 29 to increase the squeezing force on the baffle rod 37, and the distance the baffle rod 37 moves away from the end of the sleeve 22 increases. The baffle rod 37 drives the drum screen 18 to squeeze the elastic connecting ring 16 and multiple return springs 38 to move closer to the end of the finished pipe 9. The distance that the drum screen 18 squeezes the pressure bellows 36 increases, the elastic deformation of the pressure bellows 36 increases when it is compressed, the pressure generated by the pressure bellows 36 increases, and the connecting cylinder 33 is subjected to the pressure of the pressure bellows 36. The amount of finished liquid discharged to the inside of the finished pipe 9 along the one-way drain valve 32 increases, thereby ensuring that the amount of finished liquid in the finished pipe 9 is restored to the initial value, and the flow value detected by the flow sensor 31 reaches the preset flow value.

[0063] When the stirring plate 27 drives the elastic cleaning plate 29 to disengage from the blocking rod 37, the drum screen 18 is driven to move in the opposite direction to return to its original position under the elastic force of the elastic connecting ring 16 and multiple return springs 38, and the left and right vibration amplitude of the drum screen 18 in the separation chamber 2 increases, and the elastic cleaning plate 29 is cooperated to further improve the clearing effect of the slurry silicon inside the sieve hole 19 and the inner wall of the drum screen 18, thereby ensuring the normal screening effect of the sieve hole 19. At the same time, the drum screen 18 cancels the squeezing effect on the pressure bellows 36, and the pressure bellows 36 moves in the opposite direction to return to its original position under the action of its own elastic force, then the internal pressure of the pressure bellows 36 returns to the initial value, then the negative pressure suction force applied by the pressure bellows 36 to the connecting tube 33 increases, and the amount of finished liquid entering the connecting tube 33 from the one-way liquid inlet valve 35 inside the discharge hole 34 on the outer side of the drum screen 18 increases, thereby ensuring the subsequent discharge amount of the finished liquid inside the connecting tube 33, and improving the discharge and recovery efficiency of the finished liquid along the finished product pipe 9.

[0064] With long-term use, when the flow value detected by the flow sensor 31 is zero, it means that the finished liquid is no longer discharged from the finished product pipe 9, and the slurry silicon in the separation chamber 2 is stirred and separated. The control panel 6 controls the solenoid valve 11 to open, and the impurities in the separation chamber 2 are discharged downward along the impurity discharge pipe 10. In this process, the drive shaft 20 rotates continuously and drives the sleeve 22 to rotate. The sleeve 22 drives the stirring plate 27 to rotate through the first connecting plate 25 and the second connecting plate 26. The stirring plate 27 drives the elastic cleaning plate 29 to scrape and clean the inner wall of the drum screen 18, further improving the cleanliness of the inner wall of the drum screen 18 and avoiding contamination of the subsequent stirring and separation of the slurry silicon. After the cleaning is completed, the solenoid valve 11 is closed, and the subsequent slurry silicon is re-introduced along the liquid inlet pipe 7, and the above process is repeated to stir and separate the subsequent slurry silicon.

[0065] The slurry silicon stirring and separation kettle is simple to operate, has a high safety factor, strong adaptability, high stability, meets actual processing needs, and can realize rapid and efficient separation of slurry silicon, meets mass production needs, saves energy and reduces emissions, and is green and environmentally friendly; and when stirring and separating the slurry silicon, the inclination angle of the stirring plate 27 is adjusted to thereby realize upward lifting and stirring of the slurry silicon at the bottom of the separation chamber 2, thereby preventing the slurry silicon from settling at the bottom of the separation chamber 2 and reducing the stirring and separation effect; at the same time, during the rotation of the stirring plate 27, the baffle rod 37 is used to The drum screen 18 is driven to vibrate inside the separation chamber 2, and the elastic cleaning plate 29 is driven to rotate in cooperation with the stirring plate 27, so as to improve the unblocking effect on the inner wall of the drum screen 18 and the inside of the sieve hole 19, and avoid reducing the subsequent discharge efficiency of the finished liquid and the screening effect of the slurry silicon; and during the left and right vibration process of the drum screen 18, the reciprocating squeezing of the pressure bellows 36 can be realized to achieve unidirectional discharge of the finished liquid on the outside of the drum screen 18 along the connecting tube 33 to the finished product pipe 9, with high recovery efficiency and good recovery effect, meeting the demand for fast and efficient recovery of the finished liquid.

[0066] The separation method of the slurry silicon stirring separation kettle as described above comprises the following steps:

[0067] S1. Add slurry silicon into the drum screen 18, drive the shaft 20 to rotate clockwise and drive the outer sleeve 22 to rotate clockwise, the sleeve 22 rotates and drives the plurality of stirring plates 27 to rotate clockwise and stir and separate the slurry silicon inside the drum screen 18.

[0068] S2, the stirring plate 27 and the baffle rod 37 squeeze each other and drive the drum screen 18 to move back and forth laterally inside the separation chamber 2. The drum screen 18 squeezes the pressure bellows 36 and changes the internal pressure of the pressure bellows 36. The finished liquid after screening by the drum screen 18 enters the finished product pipe 9 along the one-way liquid inlet valve 35 and the one-way liquid discharge valve 32, and the flow value detected by the flow sensor 31 reaches the set flow preset value.

[0069] S3. When the flow value detected by the flow sensor 31 is less than the preset flow value, the sleeve 22 moves downward along the outer surface of the drive shaft 20, and the sleeve 22 drives the threaded barrel 24 to move downward. The threaded barrel 24 is threadedly engaged with the threaded rod 21 and rotates clockwise, and the stirring plate 27 rotates synchronously.

[0070] S4, the stirring plate 27 is tilted and rotated clockwise to transmit the slurry silicon at the bottom of the separation chamber 2 upward, the stirring plate 27 and the baffle rod 37 squeeze and drive the drum screen 18 to increase the left and right vibration amplitude, the drum screen 18 squeezes the pressure bellows 36 and increases the pressure change inside the pressure bellows 36, and the amount of finished liquid that enters the finished product pipe 9 along the one-way liquid inlet valve 35 and the one-way liquid discharge valve 32 after screening by the drum screen 18 increases.

[0071] Such as the application of the slurry silicon stirring separation kettle in the battery field.
