Description

Technical Field

[0001] This utility model relates to the technical field of polyacrylamide processing equipment, specifically a polyacrylamide mother liquor transfer device. Background Technology

[0002] Polyacrylamide mother liquor is a high-concentration liquid containing polyacrylamide. It has a high concentration, high viscosity, and strong overall integrity, requiring a special transfer device for transfer.

[0003] Chinese Patent Publication No. CN220048011U discloses a polyacrylamide mother liquor transfer device, which includes a frame with a first mounting slot at the top. An outlet hole is located inside the first mounting slot, and one end of the outlet hole is fixedly connected to a first outlet pipe. A polyacrylamide mother liquor storage device is movably engaged inside the first mounting slot. This invention utilizes the movably engaged polyacrylamide mother liquor storage device inside the first mounting slot. When it is necessary to transfer polyacrylamide mother liquor from the storage device, an electric telescopic rod is activated, and a push plate squeezes the air inside the storage device, forcing the polyacrylamide mother liquor through a second outlet pipe and the outlet hole into the first outlet pipe, and then out through a metal ring, thus achieving the transfer of polyacrylamide mother liquor. This device can precisely control the volume of polyacrylamide mother liquor transferred, ensuring accurate concentration of the prepared polyacrylamide solution.

[0004] However, the polyacrylamide mother liquor transfer device disclosed in the above patent still has certain shortcomings in practical applications. Due to the high viscosity of the polyacrylamide solution, it is generally difficult to complete the extraction smoothly by direct extraction. The above patent does not have the function of stirring the polyacrylamide solution to reduce the viscosity of the polyacrylamide mother liquor and make it easier to extract. Utility Model Content

[0005] The purpose of this invention is to provide a polyacrylamide mother liquor transfer device to solve the problem mentioned in the background art that the existing polyacrylamide mother liquor transfer devices do not have the function of stirring the polyacrylamide solution.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polyacrylamide mother liquor transfer device, comprising a mother liquor transfer cylinder, wherein a control chamber and a mother liquor storage chamber are respectively opened in the upper and lower ends of the cylinder, and a suction tube connected to the mother liquor storage chamber is provided on the bottom wall of the mother liquor transfer cylinder. A lead screw is rotatably installed on the bottom wall of the control chamber, and the top of the lead screw passes through the top wall of the control chamber via a bearing. A fixing frame is fixedly installed on the outer wall of the upper cylinder of the mother liquor transfer cylinder, and a motor is fixedly installed on the top wall of the frame. The output end of the motor is connected to the top of the lead screw. A movable plate is provided in the control chamber and screwed to the surface of the lead screw. A piston plate is installed in the mother liquor storage chamber, and a movable rod is fixedly connected between the top walls on both sides of the piston plate and the bottom walls on both sides of the movable plate. The rod of the movable rod movably passes through the bottom wall of the control chamber. An auxiliary transfer mechanism is provided outside the cylinder of the mother liquor transfer cylinder.

[0007] Preferably, the auxiliary transfer mechanism includes a toothed ring rotatably connected to the outer wall of the bottom cylinder of the mother liquor transfer cylinder, and a plurality of stirring rods arranged in a circumferential array are fixedly installed on the bottom wall of the toothed ring.

[0008] Preferably, the auxiliary transfer mechanism further includes a first spur gear fixedly installed on the surface of the upper part of the lead screw, and two fixing blocks are fixedly installed on the outer wall of the mother liquor transfer cylinder in the vertical direction, with a transmission rod installed through the plates of the two fixing blocks via a bearing.

[0009] Preferably, a second spur gear is fixedly installed on both ends of the transmission rod. The second spur gear at the top meshes with the first spur gear, and the second spur gear at the bottom meshes with the gear ring.

[0010] Preferably, the suction tube is equipped with a solenoid valve.

[0011] Preferably, the cross-sections of both the control chamber and the mother liquor storage chamber are circular.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves inserting a suction tube at the bottom of the mother liquor transfer cylinder into the polyacrylamide mother liquor. As the motor starts, it drives the lead screw to rotate, which in turn drives the first spur gear. Since the first and second spur gears mesh, the first spur gear drives the second spur gear to rotate, which in turn drives the transmission rod to rotate. This causes the second spur gear at the bottom of the transmission rod to rotate the toothed ring on the surface of the mother liquor transfer cylinder. The rotation of the toothed ring causes multiple stirring rods on the bottom wall of the toothed ring to rotate and stir the polyacrylamide mother liquor, thereby reducing its viscosity and making it easier to extract. Simultaneously, as the lead screw rotates, a moving plate rises along the lead screw. Under the action of the movable rod, the rising moving plate drives the piston plate to rise along the mother liquor storage chamber, thus allowing the polyacrylamide mother liquor to be drawn into the mother liquor storage chamber by the suction tube, completing the mother liquor transfer process.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a technical solution: a polyacrylamide mother liquor transfer device, including a mother liquor transfer cylinder 1, a control chamber 12 and a mother liquor storage chamber 13 respectively opened in the upper and lower end cylinders of the mother liquor transfer cylinder 1, a suction pipe 9 connected to the mother liquor storage chamber 13 is set in the bottom wall of the mother liquor transfer cylinder 1, the bottom end of the lead screw 14 is rotatably mounted on the bottom wall of the control chamber 12 via a bearing, the top end of the lead screw 14 passes through the top wall of the control chamber 12 via a bearing, a fixing frame 2 is welded to the upper outer wall of the mother liquor transfer cylinder 1, and a motor. 3 is fixed to the top wall of the frame of the fixed frame 2 by screws. The output end of the motor 3 is connected to the top rod of the lead screw 14 via a coupling. The movable plate 15, which is screwed to the surface of the lead screw 14, is set in the cavity of the control cavity 12. The piston plate 17 is installed in the cavity of the mother liquor storage cavity 13. Two movable rods 16 are fixedly connected between the top walls of the left and right sides of the piston plate 17 and the bottom walls of the left and right sides of the movable plate 15. The rod of the movable rod 16 moves through the bottom wall of the cavity of the control cavity 12. The auxiliary transfer mechanism is set outside the cylinder of the mother liquor transfer cylinder 1.

[0021] The auxiliary transfer mechanism includes a gear ring 8 rotatably connected to the outer wall of the bottom cylinder of the mother liquor transfer cylinder 1 via a bearing. Multiple stirring rods 11 arranged in a circumferential array are welded to the bottom wall of the gear ring 8. The auxiliary transfer mechanism also includes a first spur gear 6 welded to the surface of the upper rod of the lead screw 14. Two fixed blocks 4 are welded to the outer wall of the cylinder of the mother liquor transfer cylinder 1 in the vertical direction. The transmission rod 5 is installed between the plates of the two fixed blocks 4 via a bearing. A second spur gear 7 is welded to both ends of the transmission rod 5.

[0022] When in use, open the solenoid valve 10 and insert the suction tube 9 at the bottom of the mother liquor transfer cylinder 1 into the polyacrylamide mother liquor. As the motor 3 starts, it drives the lead screw 14 to rotate. The rotation of the lead screw 14 drives the first spur gear 6 to rotate. Since the first spur gear 6 and the second spur gear 7 mesh with each other, the first spur gear 6 drives the second spur gear 7 to rotate. The rotation of the second spur gear 7 drives the transmission rod 5 to rotate. As a result, the second spur gear 7 at the bottom of the transmission rod 5 drives the toothed ring 8 on the surface of the mother liquor transfer cylinder 1 to rotate. The rotation of the toothed ring 8 drives the multiple stirring rods 11 on the bottom wall of the toothed ring 8 to rotate and stir in the polyacrylamide mother liquor, thereby reducing the viscosity of the polyacrylamide mother liquor and making it easier to extract. At the same time as the lead screw 14 rotates, the moving plate 15 rises along the lead screw 14. Under the action of the movable rod 16, the moving plate 15 rises and drives the piston plate 17 to rise along the mother liquor storage chamber 13, thereby allowing the polyacrylamide mother liquor to be drawn into the mother liquor storage chamber 13 by the suction tube 9 to complete the mother liquor transfer. After the transfer is completed, the solenoid valve 10 can be closed.
