Description

Technical Field

[0001] This utility model relates to the field of rotary dryer technology, and in particular to a rotary dryer suitable for high moisture content materials. Background Technology

[0002] Rotary dryers are a type of high-efficiency drying equipment widely used in various industries. Their core feature is that they achieve rapid drying of materials through high-speed airflow and structural optimization. The high-speed rotating cylinder, in conjunction with the hot air system, evenly throws and exposes the material to the high-temperature airflow. Moisture evaporation is achieved through heat conduction, convection, and radiation. The material is folded back and evenly distributed within the cylinder by spiral blades or intermittent spiral lifting plates. The sleeve-and-row structure shortens the heat dissipation surface while increasing the heat exchange area, thereby improving thermal efficiency.

[0003] Existing drying equipment mostly uses single-drum or vertical dryers, which have high requirements for materials. When the material has a high moisture content, it needs to be sun-dried to reduce the moisture content. Otherwise, it cannot be dried effectively. In addition, some materials contain lumps that cannot be effectively broken up during the drying process, which greatly affects the drying effect. Therefore, a rotary dryer suitable for high moisture materials is designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotary dryer suitable for high-moisture materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotary dryer suitable for high-moisture materials includes a feed cylinder, a rotating tube rotatably connected to the outside of the feed cylinder, a discharge cylinder rotatably connected to the outside of the rotating tube, a drive motor fixedly connected to the feed cylinder, a rotating shaft fixedly connected to the output end of the drive motor, multiple push rod grooves on the side wall of the rotating shaft, a spiral plate fixedly connected to the rotating shaft, and a stirring assembly installed on the outside of the rotating shaft. The stirring assembly includes multiple sleeves slidably fitted onto the outside of the rotating shaft, multiple cavities inside the rotating shaft, the number and position of each cavity corresponding to the sleeves, a lifting plate rotatably connected to the outside of each sleeve, a fixed push rod slidably connected to each lifting plate, a conical push rod fixedly connected to one side of the fixed push rod located inside the cavity, and a buffer spring fixedly connected between the cavity and the conical push rod. Multiple stirring blades slidably penetrate the side wall of each cavity.

[0007] Preferably, each of the stirring blades is fixedly connected to a fixing plate at one end within the cavity, and a fixing spring is fixedly connected between the fixing plate and the cavity.

[0008] Preferably, a base is fixedly connected to the lower side of the feed cylinder via a support frame, a motor support frame is fixedly connected to the upper side of the base, a dual-axis motor is fixedly connected to the upper side of the motor support frame, drive gears are fixedly connected to the output ends on both sides of the dual-axis motor, and two toothed rings are fixedly connected to the outer side of the rotating tube, with the two toothed rings meshing with the drive gears.

[0009] Preferably, a feed funnel is fixedly connected to the upper side of the feed cylinder, and a filter screen is clamped inside the feed funnel.

[0010] Preferably, the rotating tube has multiple heating chambers on its side wall, and each heating chamber is fixedly connected with a heating resistance wire.

[0011] Preferably, sealed bearings are fixedly connected between the feed cylinder and the rotating tube, and between the rotating tube and the discharge cylinder.

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

[0013] 1. After the material enters this device, it is propelled into the rotating tube by the propulsion of the spiral plate. The lifting plate in the rotating tube can fully stir the material, and the lifting plate can rotate during the collision with the material to further enhance the stirring of the material.

[0014] 2. When encountering agglomerated material that the lifting plate cannot break up, the lifting plate deflects under the impact of the agglomerated material, causing the mixing blades to extend further to break up the agglomerated material. Attached Figure Description

[0022] Reference Figures 1-6 A rotary dryer suitable for high-moisture materials includes a feed cylinder 1, a rotating tube 9 rotatably connected to the outside of the feed cylinder 1, a discharge cylinder 11 rotatably connected to the outside of the rotating tube 9, a drive motor 3 fixedly connected to the side wall of the feed cylinder 1, a rotating shaft 16 fixedly connected to the output end of the drive motor 3, multiple push rod grooves 22 opened on the side wall of the rotating shaft 16, a spiral plate 12 fixedly connected to the rotating shaft 16, and a stirring assembly installed on the outside of the rotating shaft 16, the stirring assembly including a slidably sleeved on the outside of the rotating shaft 16. Multiple sleeves 23 are located on the side, and multiple cavities 14 are opened inside the rotating shaft 16. The number and position of each cavity 14 are opposite to the sleeves 23. Each sleeve 23 is rotatably connected to a lifting plate 24. Each lifting plate 24 is slidably connected to a fixed push rod 15. A conical push rod 17 is fixedly connected to one side of the fixed push rod 15 inside the cavity 14. A buffer spring 20 is fixedly connected between the cavity 14 and the conical push rod 17. Multiple stirring blades 25 are slidably connected through the side wall of each cavity 14.

[0023] Each stirring blade 25 is located inside the cavity 14, with one end fixedly connected to a fixing plate 21. A fixing spring 18 is fixedly connected between the fixing plate 21 and the cavity 14. When the agglomerates are broken, the stirring blade 25 returns to its original position under the action of the fixing spring 18. Figure 3 and 4 As shown, the fixing plates 21 at the ends of the multiple stirring blades 25 located in the cavity 14 together form an approximate cylinder. When the conical push rod 17 passes through this approximate cylinder, each stirring blade 25 can extend outward, thereby increasing its crushing range.

[0024] A base 4 is fixedly connected to the lower side of the feed cylinder 1 via a support frame 5. A motor support frame 7 is fixedly connected to the upper side of the base 4. A dual-shaft motor 8 is fixedly connected to the upper side of the motor support frame 7. Drive gears 6 are fixedly connected to the output ends on both sides of the dual-shaft motor 8. Two toothed rings 10 are fixedly connected to the outer side of the rotating tube 9. The two toothed rings 10 mesh with the drive gears 6.

[0025] A feeding funnel 2 is fixedly connected to the upper side of the feeding cylinder 1. A filter screen is inserted into the feeding funnel 2 to perform preliminary filtration on the incoming material, which can effectively remove some impurities and improve the drying efficiency.

[0026] The rotating tube 9 has multiple heating chambers 19 on its side wall. Each heating chamber 19 is fixedly connected to a heating resistance wire 13. A fixed power supply is also fixedly installed in the heating chamber 19. The fixed power supply and the heating resistance wire 13 are electrically connected. When drying and stirring, the fixed power supply is turned on to heat the material inside the rotating tube 9 and evaporate the moisture in the material.

[0027] Sealed bearings are fixedly connected between the feed cylinder 1 and the rotating tube 9, and between the rotating tube 9 and the discharge cylinder 11. The rotating tube 9 can rotate continuously to ensure that the material is fully stirred.

[0028] In this utility model, when drying is required, the dual-shaft motor 8 is started first. The dual-shaft motor 8 drives the rotating tube 9 to rotate through the drive gear 6 and the gear ring 10, so that the material is fully stirred and the drying efficiency is improved. At the same time, the fixed power supply is started to heat the material inside the rotating tube 9 and evaporate the moisture in the material. The above are all existing technologies and will not be described in detail.

[0029] When the material enters the feed cylinder 1 through the feed funnel 2, the drive motor 3 is started. The drive motor 3 drives the rotating shaft 16 and the spiral plate 12 to rotate. The spiral plate 12 pushes the material into the rotating tube 9. Driven by the rotating shaft 16, the sleeve 23 also rotates. The sleeve 23 drives the lifting plate 24 to start rotating. The lifting plate 24 continuously collides with the material, decomposes the clumps of material and improves the drying effect.

[0030] If large lumps of material are encountered during the above process, the lifting plate 23 cannot crush them. The lumps exert a pushing force on the sleeve 23. At this time, the sleeve 23 drives the conical push rod 17 to move through the fixed push rod 15. The conical push rod 17 squeezes the fixed plate 21. Due to the special shape of the conical push rod 17, when the conical push rod 17 moves to the left, the fixed plate 21 that is in contact with the conical push rod 17 will move away from the rotating shaft 16. While the fixed plate 21 compresses the fixed spring 18, it drives the stirring plate 25 to extend further outward to crush the lumps and improve the crushing effect.
