Description

Technical Field

[0001] This utility model relates to the field of sugarcane bagasse processing, and in particular to a drying device for sugarcane bagasse processing. Background Technology

[0002] Sugarcane bagasse, a major byproduct of the sugar industry, is produced in huge quantities annually. Its rational utilization is crucial for enhancing industrial added value and achieving resource recycling. Drying equipment for sugarcane bagasse processing is key to its high-value utilization. By reducing the moisture content of sugarcane bagasse, its application performance in papermaking, biomass fuel, and dietary fiber extraction can be significantly improved. The drying effect directly affects the energy consumption, efficiency, and product quality of subsequent sugarcane bagasse processing.

[0003] Currently, sugarcane bagasse drying equipment mainly employs tube bundle dryers, drum dryers, and cyclone dryers. Tube bundle dryers use steam as a heat source, indirectly heating the material through tube bundles. Although the equipment is compact, the tube walls are prone to corrosion, maintenance costs are high, and overall thermal efficiency is low. Traditional drum dryers have a simple structure, but suffer from uneven drying and agglomeration issues. Cyclone dryers offer fast drying speeds, but have high construction costs, are difficult to control, and are sensitive to fluctuations in airflow and velocity.

[0004] Existing bagasse drying equipment has significant technical shortcomings. In terms of heat exchange, traditional equipment suffers from low hot air contact efficiency and overall low heat exchange efficiency, resulting in large fluctuations in the moisture content of the dried bagasse, insufficient waste heat recovery, and high energy consumption per unit. In the feeding stage, due to the high fiber content and tendency of bagasse to clump, traditional equipment is prone to clogging, leading to uneven material distribution. This not only worsens the drying effect but also increases maintenance costs and downtime, severely hindering equipment performance improvement. Utility Model Content

The outer wall of the inner barrel 3 is fixedly connected with evenly distributed heat dissipation fins 13, and the bottom of the inner wall of the outer barrel 2 is fixedly connected with a spiral heating tube 12. A heat-conducting liquid is placed in the gap between the outer barrel 2 and the inner barrel 3, and the spiral heating tube 12 heats it. A spiral blade 10 is fixedly connected through the bottom of the outer ring of the first rotating shaft 8. The rotation of the first motor 7 drives the spiral blade 10 to rotate, which can turn the sugarcane bagasse and turn the sugarcane bagasse at the bottom to the top. The heat-conducting liquid is heated stably. The spiral heating tube 12 can be started to heat the heat-conducting liquid at the beginning of processing, and the hot air can be used to quickly heat the inside of the inner barrel 3. After the temperature is reached, the heating of the spiral heating tube 12 is stopped. The heat dissipation fins 13 can enhance heat conduction and transfer the heat generated by the hot air in the inner barrel 3 to the heat-conducting liquid, reducing heat waste. A transmission component is set at the top of the first connecting pipe 9, and a dispersing component is set at the top of the first support frame 6.

[0036] The transmission assembly includes a bidirectional connecting hose 17. The top of the first rotating shaft 8 is rotatably connected to one end of the bidirectional connecting hose 17, and both ends of the bidirectional connecting hose 17 are connected to the sealing cap 5. The bidirectional ends of the bidirectional connecting hose 17 transmit hot air to the first rotating shaft 8 and the top space of the inner barrel 3, respectively. A cavity 31 is opened inside the first rotating shaft 8. The outer ring of the second connecting pipe 11 is connected to evenly distributed air outlet pipes 14. The transmitted hot air passes through the cavity 31, the first connecting pipe 9, and the second connecting pipe 11, and is evenly distributed from the air outlet pipes. The gas outlet pipe 14 is sprayed out, and a gas one-way valve 15 is fixedly connected inside each of the gas outlet pipes 14. A filter screen 16 is fixedly connected to one end of the inner wall of each gas outlet pipe 14. The gas one-way valve 15 and the filter screen 16 prevent sugarcane bagasse from entering the transmission component. The dispersing component includes a second support frame 18. The top of the first support frame 6 is fixedly connected to the bottom of the second support frame 18. A second motor 19 is fixedly connected to the top of the second support frame 18. A dispersing chamber 22 is fixedly connected to the top wall inside the second support frame 18. A second rotating shaft 20 is fixedly connected to the output end of the second motor 19. The outer ring is fixedly connected with evenly distributed connecting rods 21. A damping spring damper 24 is fixedly connected to one side of the top of the first support frame 6. A vibration frame 23 is fixedly connected to the top of each damping spring damper 24. A third motor 25 is fixedly connected to the other side of the top of the first support frame 6. A rotating rod 27 is fixedly connected to the output end of the third motor 25. Support blocks 26 are rotatably connected to both ends of the outer ring of the rotating rod 27, and the support blocks 26 are fixedly connected to the first support frame 6. A cam 28 is fixedly connected to one end of the rotating rod 27. The high-speed rotating connecting rod 21... 1. It can effectively break up high-fiber materials and reduce the risk of them entangled in the equipment; the vibrating screen prevents large particles from accumulating on the vibrating frame 23, ensuring that the broken sugarcane bagasse can enter the inner barrel 3 through the open sealing cover 5. One end of the bidirectional connecting hose 17 is equipped with an air heating component 29, which includes a heating box and a fan. The output end of the fan is connected to the heating box through and fixedly connected. The air heating component 29 heats the air. The top of the sealing cover 5 is connected to an exhaust pipe 30 through and fixedly connected. The water vapor evaporated from the sugarcane bagasse is discharged from the exhaust pipe 30.

[0037] Working principle: First, the second motor 19 drives the second rotating shaft 20, which in turn drives the connecting rod 21 to rotate at high speed, breaking up the sugarcane bagasse clumps entering the dispersing chamber 22. The third motor 25 drives the cam 28 to rotate, impacting the vibrating frame 23 to generate high-frequency vibration, which disperses and screens the sugarcane bagasse under the support of the damping spring shock absorber 24, ensuring uniform particle size. At the same time, the sealing cover 5 opens, and the pre-treated sugarcane bagasse falls into the inner barrel 3 through the vibrating frame 23. Then, the sealing cover 5 is closed, and the spiral heating tube 12 is activated to heat the heat transfer liquid in the gap between the outer barrel 2 and the inner barrel 3. Simultaneously, the air heating component 29 delivers hot air through the bidirectional connecting hose 17 and the cavity 31 to the first connecting pipe 9 and the second connecting pipe 11. The hot air is ejected from the air outlet pipe 14, and the gas one-way valve 15 confirms the flow. The airflow is kept unidirectional, and the filter screen 16 prevents material backflow. The first motor 7 drives the spiral blades 10 to turn the sugarcane bagasse, so that the material can fully contact the hot air. The heat transfer liquid conducts heat to the inside of the inner barrel 3 through the inner barrel 3 wall and the heat dissipation fins 13. Hot air is continuously sprayed from the air outlet pipe 14, forming a composite drying mode of "hot airflow impact + mechanical turning". When the temperature of the inner barrel 3 reaches the set value, the spiral heating tube 12 stops heating. At this time, the heat dissipation fins 13 transfer the excess heat of the hot air to the heat transfer liquid to realize the recovery of waste heat. After drying is completed, the sealing cover 5 is opened and the dried sugarcane bagasse is taken out.

[0038] 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.
