[0010] Compared with the prior art, the present invention provides a solid-liquid circulation separation device for polyaluminum chloride, which has the following beneficial effects:

[0011] 1. This polyaluminum chloride solid-liquid circulation separation device allows polyaluminum chloride solution to be poured into the telescopic spring cylinder composed of an outer ring and an inner ring through a feeding pipe. The screw shaft can drive the stirring rod to rotate, thus stirring the solution circumferentially inside the telescopic spring cylinder to ensure that impurities are evenly distributed in the solution.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1-4 This utility model provides a solid-liquid circulation separation device for polyaluminum chloride, including a separation cylinder 1, an extension box 2 fixedly connected to the outer surface of the separation cylinder 1, a top cover 3 fixedly connected to the top of the separation cylinder 1 by bolts, a feeding pipe 4 fixedly connected to the upper end face of the top cover 3, a motor 5 fixedly connected to the middle of the bottom surface of the separation cylinder 1, a discharge pipe 6 fixedly connected to the outer side of the bottom surface of the separation cylinder 1, a screw shaft 7 fixedly connected to the output end of the motor 5, a hinge block 8 provided on the surface of the screw shaft 7, a stirring rod 9 rotatably connected to the screw shaft 7 through the hinge block 8, and a movable base 10 threadedly connected to the surface of the screw shaft 7.

[0020] An inner ring limiting block 11 and an outer ring limiting block 12 are fixedly connected to the upper end face of the movable base 10. A sliding rod 13 is fixedly connected to the surface of the inner ring limiting block 11. A guide rail 14 is fixedly connected to the inner bottom surface of the separation cylinder 1. A telescopic tube 15 is fixedly connected to the inner side of the outer ring limiting block 12. A pump body 16 is fixedly connected to the outer side of the outer ring limiting block 12. A return bend 17 is fixedly connected to the end face of the pump body 16. A triangular sliding groove 18 is opened inside the extension box 2. A moving rod 19 is slidably connected inside the triangular sliding groove 18. An outer ring 20 is fixedly connected to one end of the inner side of the moving rod 19. A storage cavity 21 is opened inside the outer ring 20. Limit ports 22 are opened at both ends of the storage cavity 21. Limit ports are slidably connected inside the storage cavity 21. The sliding plate 23 has an inner ring 24 fixedly connected between the two limiting sliding plates 23. A spring 25 is fixedly connected to the upper side of the limiting sliding plate 23. A secondary filtration chamber 26 is opened inside the inner ring 24. A primary filter hole 27 is opened on the inner surface of the inner ring 24. A secondary filter hole 28 is opened on the lower side of the limiting sliding plate 23. The feeding pipe 4 can pour the polyaluminum chloride solution into the telescopic spring cylinder composed of the outer ring 20 and the inner ring 24. At this time, the motor 5 is started to rotate in both directions. The motor 5 can drive the screw shaft 7 to rotate in both directions. The screw shaft 7 can drive the stirring rod 9 to rotate through the hinge block 8. Therefore, the stirring rod 9 can stir the circumference of the solution inside the telescopic spring cylinder so that the impurities are evenly distributed in the solution.

[0021] Furthermore, one end of the spring 25 is fixedly connected to the outer ring 20, and the other end of the spring 25 is fixedly connected to the inner ring 24. The outer ring 20 and the inner ring 24 are staggered and form a telescopic spring cylinder. The bottom end of the telescopic spring cylinder contacts and slides with the upper end face of the movable base 10. The top end of the return bend 17 is located above the telescopic spring cylinder. The spring 25 is arc-shaped. When the outer ring 20 and the inner ring 24 extend or contract, the spring 25 can also extend or contract. When the telescopic spring cylinder contracts, the solution inside it can shake so that impurities are evenly distributed inside the solution and the solution is prevented from settling to the bottom.

[0022] Furthermore, the storage chamber 21 is formed by the gap between its sidewall and the two limiting slide plates 23. The telescopic spring cylinder composed of the outer ring 20 and the inner ring 24 is connected to the secondary filtration chamber 26 through the primary filter hole 27. The secondary filtration chamber 26 is connected to the storage chamber 21 through the secondary filter hole 28. The solution inside the telescopic spring cylinder enters the secondary filtration chamber 26 through the primary filter hole 27, and the solution inside the secondary filtration chamber 26 enters the storage chamber 21 through the secondary filter hole 28. Thus, the solution can be filtered twice to improve the solution separation effect.

[0023] Furthermore, the triangular slide groove 18 is a right-angled triangle, and the outer end of the moving rod 19 is an inclined plane, which contacts and slides with the inclined side of the right-angled triangle slide groove 18. When the motor 5 drives the screw shaft 7 to rotate, the sliding rod 13 and the guide rail 14 guide the moving base 10 in the vertical direction, thus allowing the moving base 10 to move up and down. The moving base 10 can also drive the moving rod 19 to move via the outer ring 20, as shown in the attached instruction manual. Figure 2 As shown, when the moving rod 19 moves upward, it can also move horizontally inward, causing the telescopic spring cylinder composed of the outer ring 20 and the inner ring 24 to contract. Conversely, through the extension or contraction of the spring 25, the telescopic spring cylinder composed of the outer ring 20 and the inner ring 24 can expand, so that the solution inside the telescopic spring cylinder can be turned over by the extension or contraction of the telescopic spring cylinder, preventing impurities in the solution from settling to the bottom.

[0024] Furthermore, one end of the telescopic tube 15 is fixedly connected to the outer ring 20 and communicates with the storage chamber 21. The other end of the telescopic tube 15 is fixedly connected to the pump body 16. When the pump body 16 is started, the pump body 16 can transport the solution separated inside the storage chamber 21 back to the telescopic spring cylinder composed of the outer ring 20 and the inner ring 24 through the telescopic tube 15 and the return bend 17, so as to circulate and separate the solution.

[0025] Furthermore, the stirring rod 9 is threadedly connected to the screw shaft 7 via the hinge block 8. Multiple sets of stirring rods 9 are arranged along the circumference and axial direction of the screw shaft 7. The discharge pipe 6 passes through the movable base 10 and is slidably connected to it. The top end of the discharge pipe 6 extends into the telescopic spring cylinder formed by the outer ring 20 and the inner ring 24. When the screw shaft 7 drives the stirring rod 9 to rotate via the hinge block 8, the solution can be stirred. At this time, the movable base 10 moves along the axial direction of the screw shaft 7 without interfering with the stirring rod 9. By opening the switch valve set on the discharge pipe 6, the impurities separated in the telescopic spring cylinder can be discharged.

[0026] In use, the polyaluminum chloride solution can be poured into the telescopic spring cylinder composed of the outer ring 20 and the inner ring 24 through the feeding pipe 4. At this time, the motor 5 is started to rotate in both directions, which in turn drives the screw shaft 7 to rotate in both directions. The screw shaft 7, through the hinge block 8, drives the stirring rod 9 to rotate. Therefore, the stirring rod 9 can stir the solution circumferentially inside the telescopic spring cylinder to ensure that impurities are evenly distributed in the solution. When the screw shaft 7 rotates in both directions, the sliding rod 13 and the guide rail 14 axially guide the moving base 10, allowing the moving base 10 to move vertically. At this time, the moving base 10 can drive the moving rod 19 to move vertically through the outer ring 20, and the moving rod 19 can be obliquely guided by the triangular sliding groove 18, allowing the moving rod 19 to drive the outer ring 20 to move laterally. This allows the telescopic spring cylinder composed of the outer ring 20 and the inner ring 24 to expand or contract. At this time, the outer ring 20 can drive the telescopic tube... The telescopic tube 15 extends and retracts so that the telescopic spring ring cylinder can be horizontally guided. Therefore, when the telescopic spring ring cylinder extends or retracts, the solution inside can be turned over to prevent solid impurities from settling to the bottom. During the process of the solution being stirred and rolled, after being filtered through the primary filter hole 27, the solution enters the secondary filter chamber 26, thereby initially separating the solution from the solid impurities. The solution inside the secondary filter chamber 26 enters the storage chamber 21 after being filtered through the secondary filter hole 28, thus separating the solution from the solid impurities again. At the same time, the switch valve set on the discharge pipe 6 is opened to discharge the solid impurities inside the telescopic spring ring cylinder. Then, the discharge pipe 6 is closed again through the switch valve, and the pump body 16 can reintroduce the solution inside the storage chamber 21 into the telescopic spring ring cylinder through the telescopic tube 15 and the return bend 17. Repeating the above steps can circulate and separate the polyaluminum chloride solution to improve the separation and processing quality of the polyaluminum chloride solution.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
