[0002] Polyacrylamide, a commonly used polymer compound, requires drying of wet particles during its production process, and fluidized bed dryers are currently one of the mainstream drying equipment. However, existing fluidized bed dryers suffer from several problems in practical applications. Wet polyacrylamide particles easily agglomerate due to moisture, leading to insufficient contact between hot air and material when directly introduced into the dryer. This results in incomplete drying in certain areas and uneven moisture content in the product, severely impacting the final product quality. Therefore, those skilled in the art have provided a fluidized bed dryer for polyacrylamide to address the problems mentioned in the background section. Utility Model Content

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0013] like Figures 1-5As shown, this embodiment provides a polyacrylamide fluidized bed dryer, including a dryer body 1. The rear end of the dryer body 1 has several hot air inlets 2 connected to hot air, and the upper end of the dryer body 1 has several gas outlets 3. A vibration motor 4 is installed at the rear end of the dryer body 1. Vibration damping spring seats 5 are symmetrically installed at the lower end of the dryer body 1 for vibration reduction. A discharge port 6 for discharging dried material is located on the lower right side of the dryer body 1. A feed inlet 7 for adding material is located on the upper left side of the dryer body 1. A dispersion box 8 for dispersing wet polyacrylamide particles is installed above the feed inlet 7. An inlet 9 is located at the upper end of the dispersion box 8. A dispersion frame 10 is slidably connected inside the dispersion box 8. A grid area 11 is located at the bottom of the dispersion frame 10. The inner wall of the dispersion frame 10... The dispersion frame 10 is equipped with partitions 12, and several impact tips 13 are installed on the left and right walls and both ends of the partitions 12. Sliding mechanisms 14 are symmetrically arranged on the sides of the dispersion frame 10 and are fixedly connected to the inner wall of the dispersion chamber 8. The reciprocating movement of the dispersion frame 10 causes the wet polyacrylamide particles to impact the partitions 12 and impact tips 13, dispersing the clumps of wet polyacrylamide particles. Then, qualified wet polyacrylamide particles are screened out through the grid area 11 for drying. The sliding mechanism 14 includes a fixed rod 15 and a slider 17. The fixed rod 15 is fixed to the inner wall of the dispersion chamber 8, and a groove 16 is formed on the side of the fixed rod 15. The slider 17 is slidably connected inside the groove 16 and is fixedly connected to the dispersion frame 10. The slider 17 moves within the groove 16. This restricts the movement direction of the dispersion frame 10. A sliding rod 18 is installed on the side of the dispersion frame 10, and the sliding rod 18 passes through the dispersion box 8. The sliding rod 18 is rotatably connected to a connecting rod 19 on its side. The connecting rod 19 is rotatably connected to a rotating plate 20. A rotating shaft 21 is installed at the lower end of the rotating plate 20, and a motor 22 is installed at the lower end of the rotating shaft 21. The motor 22 drives the rotating plate 20 to rotate. The rotating plate 20 drives the sliding rod 18 to reciprocate through the connecting rod 19, thereby driving the dispersion frame 10 to reciprocate to disperse the wet polyacrylamide particles. An impact unblocking mechanism 23 is provided on the lower side of the dispersion frame 10, and a transmission mechanism is provided on the side of the dispersion box 8. The impact unblocking mechanism 23 includes a grooved rod 24 and an impact plate 28. The grooved rod 24 is fixed to the inner wall of the dispersion box 8. The end face is spiked. A reciprocating screw 25 is rotatably connected inside the grooved rod 24. One end of the reciprocating screw 25 passes through the grooved rod 24 and the dispersion box 8 to install a bevel gear 34. A reciprocating block 26 is sleeved on the outer surface of the reciprocating screw 25. A horizontal plate 27 is installed at the lower end of the reciprocating block 26. Moving rods 30 are symmetrically slidably connected inside the horizontal plate 27. Impact plates 28 are installed on the upper ends of the two moving rods 30. Several impact protrusions 29 are installed on the upper ends of the impact plates 28. A mating plate 31 is installed on the lower ends of the two moving rods 30. A spring 33 is sleeved on the outer surface of the moving rods 30 and is located on the upper side of the horizontal plate 27. A second vibration motor 32 is installed at the lower end of the mating plate 31. The second vibration motor 32 drives the mating plate 31 to vibrate up and down. The spring 33 causes the impact plates 28 to drive the impact protrusions 29 to vibrate.The impact protrusion 29 impacts the grid area 11, causing the polyacrylamide particles blocking the grid area 11 to fall off, thus ensuring the unobstructed flow of the grid area 11. The transmission mechanism includes a transmission rod 35, a transmission rod 37, and a bevel gear 40. The transmission rod 35 and the transmission rod 37 are rotatably connected to the side of the dispersion box 8. Bevel gears 36 are installed at both ends of the transmission rod 35, and one bevel gear 36 meshes with bevel gear 34. A large bevel gear 38 is installed at one end of the transmission rod 37, and the large bevel gear 38 meshes with another bevel gear 30. 6. A bevel gear 39 is mounted on the other end of transmission rod 2 (37). A bevel gear 40 is mounted on the outer surface of rotating shaft 21, and bevel gear 40 meshes with bevel gear 39. Rotating shaft 21 drives large bevel gear 38 to rotate via bevel gear 40 and bevel gear 39. Large bevel gear 38 drives reciprocating screw 25 to rotate slowly via bevel gear 2 (36) and bevel gear 1 (34). Reciprocating screw 25 drives mating plate 31 to move slowly via reciprocating block 26, thereby driving impact plate 28 to move slowly to clear all positions in grid area 11.
[0014] The working principle of this utility model is as follows: wet polyacrylamide granules are poured into the dispersion box 8 through the inlet 9, so that the wet polyacrylamide granules fall into the dispersion frame 10. At the same time, the motor 22 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the rotating plate 20 to rotate, the rotating plate 20 drives the sliding rod 18 to move back and forth through the connecting rod 19, the sliding rod 18 drives the dispersion frame 10 to move back and forth, and at the same time, the slider 17 moves back and forth in the chute 16, so that the wet polyacrylamide granules collide in the dispersion frame 10. The impact tip 13 disperses the wet polyacrylamide granules that have formed clumps. Then, the wet polyacrylamide granules are screened through the grid area 11, so that the wet polyacrylamide granules that have formed clumps continue to disperse in the dispersion frame 10. The qualified wet polyacrylamide granules enter the drying bed body 1 through the grid area 11 and the feed inlet 7 for drying. Vibration motor 22 drives mating plate 31 to vibrate up and down. Spring 33 causes impact plate 28 to vibrate impact protrusion 29. Impact protrusion 29 impacts grid area 11, causing polyacrylamide particles blocked in grid area 11 to fall down, thus ensuring the grid area 11 is unobstructed. At the same time, rotating shaft 21 drives large bevel gear 38 to rotate through bevel gear 40 and bevel gear 39. Large bevel gear 38 drives reciprocating screw 25 to rotate slowly through bevel gear 26 and bevel gear 1. Reciprocating screw 25 drives mating plate 31 to move slowly through reciprocating block 26, thus driving impact plate 28 to move slowly to clear all positions in grid area 11.
