Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a polyacrylamide reactive polymerization drying device. Background Technology

[0002] Polyacrylamide is a linear polymer that is a hard, glassy solid at room temperature. Products include liquids, latexes, white powders, translucent beads, and flakes.

[0003] The existing polyacrylamide reactive polymerization drying equipment conveys polyacrylamide particles containing moisture into the equipment through the feed inlet, and then dries the polyacrylamide particles through the hot air mechanism at the bottom of the equipment. The dried polyacrylamide particles are blown up to the inner spiral feeding pipe, and then the floating polyacrylamide particles are horizontally transported to the next process by the spiral feeding shaft.

[0004] However, most existing polyacrylamide reactive polymerization drying devices transport polyacrylamide particles containing moisture into the device through a feed inlet on one side. Due to the large initial weight of the water-containing particles and the hot air vent being located at the bottom of the device, the wet particles tend to accumulate in the area near the feed inlet after entering, resulting in a weakening of the airflow around the feed inlet. Subsequently entering particles cannot obtain sufficient upward airflow and settle prematurely in front of the feed inlet, making it difficult for the particles to spread evenly throughout the device. At the same time, the airflow from the drying vent on the side away from the feed inlet is not effectively utilized, resulting in low drying efficiency of polyacrylamide particles.

[0014] This utility model has the following beneficial effects: 1.

When air inlet one is open and air inlet two is blocked, the filling of wet particles in the rotating drum is accelerated. When air inlet one is blocked and air inlet two is open, the particles are evenly blown into the drying chamber by high-speed airflow. This avoids the problem that wet particles tend to accumulate in the area near the feed inlet after entering the drying chamber, which would weaken the airflow around the feed inlet and cause the dried particles to settle prematurely, thus improving the drying efficiency of polyacrylamide particles.

[0018] 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.

[0019] Reference Figure 1-6 This utility model provides a drying device for the reactive polymerization of polyacrylamide, comprising a drying chamber 1, a mounting plate 2 fixedly connected to one side of the drying chamber 1, a fixed cylinder 3 fixedly connected to the top of the mounting plate 2, a rotating cylinder 4 rotatably connected inside the fixed cylinder 3, a gear 5 fixedly fitted on the outer surface of the rotating cylinder 4, a stirring mechanism inside the rotating cylinder 4, two air inlets 6 on the front of the rotating cylinder 4, and two air inlets 7 on both the fixed cylinder 3 and the rotating cylinder 4. A blower 8 is fixedly connected to one side of the mounting plate 2. The blower 8 has air supply pipe 1 9, air supply pipe 2 10 and air supply pipe 3 11 fixedly connected to its air outlet. A transmission mechanism is provided on one side of the drying chamber 1. A collection frame 12 is fixedly connected to the top of the drying chamber 1. A conveying mechanism is provided inside the collection frame 12. A discharge pipe 23 is provided on one side of the collection frame 12. A feed pipe 24 is provided on the front of the rotating cylinder 4. An air outlet plate 25 is fixedly connected inside the drying chamber 1. Several heating plates 26 are fixedly connected between the two sides of the inner wall of the drying chamber 1. A control panel 27 is provided on the front of the drying chamber 1.

[0020] The other end of the air supply pipe 9 is fixedly connected to the fixed cylinder 3. The other end of the air supply pipe 10 is rotatably connected to the rotating cylinder 4 through the rotating ring 28. The other end of the air supply pipe 11 is fixedly connected to the drying box 1. The fixed cylinder 3 is fixedly connected to the drying box 1.

[0021] The stirring mechanism includes a stirring frame 13 rotatably connected to the back of the rotating cylinder 4, and a wind shield 14 and a rotating wheel 15 are fixedly sleeved on the outer surface of the stirring frame 13. By using the mixing mechanism, transmission mechanism and other structures together, the mixing frame 13 can rotate continuously inside the rotating drum 4 to mix the undried particles that are fed in, prevent the undried particles from sticking to the inside of the rotating drum 4, and make the undried particles more evenly mixed, thereby improving the feeding efficiency.

[0022] The transmission mechanism includes a dual-shaft motor 16 fixedly installed on one side of the drying oven 1. Both output ends of the dual-shaft motor 16 are fixedly connected to rotating shafts 17. One rotating shaft 17 has a gear 18 fixedly sleeved on its outer surface, and the other rotating shaft 17 has a rotating wheel 19 fixedly sleeved on its outer surface. Gear 15 meshes with gear 18, and rotating wheel 19 is connected to rotating wheel 15 via belt 20. By using the rotating drum 4, blower 8, air supply pipe 1 9, air supply pipe 2 10 and transmission mechanism in combination, the air inlet 1 6 and air inlet 2 7 can be switched periodically when the rotating drum 4 rotates. When air inlet 1 6 is open and air inlet 2 7 is blocked, the filling of wet particles in the rotating drum 4 is accelerated. When air inlet 1 6 is blocked and air inlet 2 7 is open, the particles are blown evenly into the drying chamber 1 by high-speed airflow. This avoids the problem that wet particles tend to accumulate in the area near the feed inlet after entering the drying chamber 1, which would weaken the airflow around the feed inlet and cause the dried particles to settle prematurely. This improves the drying efficiency of polyacrylamide particles.

[0023] The conveying mechanism includes a drive motor 21 fixedly installed on one side of the collection frame 12. The output end of the drive motor 21 is fixedly connected to a spiral conveying blade 22, which is rotatably connected to the collection frame 12.

[0024] Working principle: When it is necessary to dry polyacrylamide granules, the operator conveys the granules to be dried into the rotating drum 4 through the feed pipe 24. At the same time, the blower 8, the dual-shaft motor 16 and the heating rod are started through the control panel 27. The blower 8 draws air from the surroundings through its exhaust end and delivers the air to the air supply pipe 1 9, the air supply pipe 2 10 and the air supply pipe 3 11 respectively through its exhaust end. Air from the air supply duct 9 is blown into the rotating cylinder 4 from one side through the air inlet 6, pushing the particles into the rotating cylinder 4 to spread quickly and evenly. At the same time, the dual-shaft motor 16 drives two rotating shafts 17 to rotate synchronously. One rotating shaft 17 drives the gear 18 to rotate, which in turn drives the gear 5 and the rotating cylinder 4 to rotate. The other rotating shaft 17 drives the rotating wheel 19 to rotate. The rotating wheel 15, the stirring rack 13, and the wind shield 14 are rotated via the belt 20, so that the rotating cylinder 4 and the stirring rack 13 rotate in opposite directions. When the air inlet 2 7 on the rotating cylinder 4 coincides with the corresponding air inlet 2 7 on the fixed cylinder 3, the wind shield 14 just rotates to the position of the air inlet 1 6 to block it. At this time, the high-speed airflow in the air supply pipe 2 10 enters the rotating cylinder 4 through the air inlet 2 7 and blows the particles to be dried above the stirring rack 13 evenly into the drying box 1. Meanwhile, the air supplied by the air supply pipe 11 enters the drying chamber 1, is heated by the heating rod to form hot air, and is blown towards the collection frame 12. The particles falling into the drying chamber 1 float towards the collection frame 12 under the action of the hot air at the bottom. As the moisture decreases and the weight decreases during continuous drying, the particles gradually rise. When the particles enter the collection frame 12, they are driven by the spiral conveyor blade 22 to move towards the discharge pipe 23 and are transported to the next process. During this continuous conveying process, the stirring rack 13 continuously rotates inside the rotating drum 4 to stir the undried particles that are being conveyed in, preventing the undried particles from sticking to the inside of the rotating drum 4, and making the undried particles more evenly mixed.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
