Technical Field

[0001] This utility model belongs to the field of feeding technology, specifically relating to a feeding device for a dryer used in the preparation of propylene catalysts. Background Technology

[0002] Propylene, as an important basic chemical raw material, is widely used in the production of chemicals such as polypropylene, acrylonitrile, and propylene oxide, and is the cornerstone of the modern petrochemical industry. In recent years, driven by the rapid growth in demand for downstream propylene derivatives, especially polypropylene, propylene consumption has increased significantly, indicating huge market potential. The crystallization solution mixture after the reaction vessel is prepared needs to be dried. Traditionally, a large number of dryers are used for drying, and material trays are usually transported back and forth between the reaction vessel and the dryer using trolleys. This method of transportation is slow and the drying speed is relatively fixed. Utility Model Content

Detailed Implementation

[0016] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0017] Example 1

[0018] like Figures 1 to 3As shown; a feeding device for a dryer used in the preparation of propylene catalyst includes a movable base 1, an upper plate 2, rotating rods 3, adjusting material transfer devices 4, a material tray 5, a power unit, a transmission belt, and a drive wheel. Several rotating rods 3 are connected between the movable base 1 and the upper plate 2, with one end connected to a drive wheel. The drive wheels on adjacent rotating rods 3 are connected via the transmission belt. The power unit is connected to one of the rotating rods 3. Several adjusting material transfer devices 4 are slidably connected to the rotating rods 3. The material tray 5 is disposed on the adjusting material transfer devices 4. The adjusting and transferring device 4 includes a lifting and adjusting frame 41, adjusting sleeves 42, a rotating wheel 43, a rotating shaft 44, a rotating plate 45, a lower rotating plate 47, connecting rods 48, a tilting device 49, and a steel cable ring. Several adjusting sleeves 42 are connected to the lifting and adjusting frame 41. The rotating wheel 43 is movably connected to the adjusting sleeves 42. The rotating shaft 44 is movably connected to the lifting and adjusting frame 41, with its two ends connected to the rotating plate 45 and the lower rotating plate 47 respectively. Several connecting rods 48 are connected to the lower rotating plate 47. The tilting device 49 is connected to... On the connecting rod 48, the rotating wheel 43 is connected to the rotating plate 45 via a steel cable ring. A fixing bolt is connected to the adjusting sleeve 42. The rotating rod 3 has a sliding groove, and a slider that mates with the sliding groove is connected to the rotating wheel 43. The flipping device 49 includes a flipping inclined block 410, a flipping rod 411, a bearing 412, a hinge rod 413, a flipping plate 414, and a C-shaped lifting rod 415. The C-shaped lifting rod 415 is connected to one end of the flipping plate 414, and several hinge rods 413 are hinged at one end to the flipping plate 414 and at the other end... The bearing 412 is sleeved on the connecting rod 48, and the flipping rod 411 is connected to the bearing 412. One end of the flipping rod 411 passes through the C-shaped cantilever rod 415 and the other end cooperates with the flipping inclined block 410. The flipping inclined block 410 is connected to the lifting adjustment frame 41. Both the rotating wheel 43 and the rotating plate 45 are provided with annular limiting grooves 46 that cooperate with the steel cable ring. A roller is connected to the end of the flipping rod 411 near the flipping inclined block 410. The annular limiting groove 46 is provided with a textured pattern.

[0019] The power unit drives the rotating rod 3 to rotate, and the slider rotates around the rotating rod 3. At the same time, the slider drives the rotating wheel 43 to rotate. The rotating wheel 43 drives the rotating plate 45 to rotate through the steel cable ring. The rotating plate 45 then drives the rotating shaft 44, the lower rotating plate 47, the connecting rod 48, and the flipping device 49 in sequence, causing the flipping device 49 to rotate around the rotating shaft 44. When the rotating plate 45 rotates, the material tray 5 on it rotates accordingly. When the flipping device 49 is working, as the connecting rod 48 rotates around the rotating shaft 44, one end of the flipping rod 411 gradually contacts and disengages from the flipping inclined block 410, causing the other end of the flipping rod 411 to lift the C-shaped lifting rod 415 on the flipping plate 414, thereby controlling the flipping plate 414 to move and rise. At this time, the flipping plate 414 will lift up the crystallized material and the original liquid. Since the original liquid has fluidity... A certain amount of raw liquid is spread on the turning plate 414 to improve the drying effect. To increase the amount of raw liquid picked up, the turning plate 414 can be designed as an arc, semi-circle, or bucket shape. The turning plate 414 acts on the material in the material tray 5 below it. The end of the hinge rod 413 that is hinged to the turning plate 414 needs to be higher than the material tray 5 to facilitate the removal of the material tray 5. The adjusting sleeve 42 is fixed by the fixing bolt to facilitate the adjustment of the height of the material transfer device 4. The friction between the annular limiting groove 46 and the steel cable ring is increased by the interlocking pattern. The turning rod 411 contacts the turning inclined block 410 through the roller to avoid direct friction and production noise. Its feeding device can be directly pushed to the reaction vessel for direct feeding, or the material tray 5 can be removed for loading and unloading, thereby improving the drying efficiency.
