Technical Field
[0001] This utility model relates to the field of fluidized bed technology, and in particular to a sulfasalazine fluidized bed with a dust removal mechanism. Background Technology
[0002] Sulfasalazine is an organic compound with the chemical formula C18H14N4O5S. It is mainly used as a sulfonamide antibacterial drug. It is a sulfonamide drug that is not easily absorbed orally. The absorbed portion is decomposed into 5-aminosalicylic acid and sulfapyridine by intestinal microorganisms. Fluidized beds are used in the processing of sulfasalazine.
[0003] For example, a patent entitled "A Fluidized Bed" (patent application number: CN202120323389.9) discloses a fluidized bed in which external air is drawn into the heating box by a fan, filtered by a dust removal screen, and then blown onto the heating mechanism for heating. Finally, the air is evenly blown into the bottom cover through the air inlet pipe and the air distribution pipe, thereby keeping the hot air evenly passing through the inclined plate to provide power to the material. However, dust and other impurities are easy to adhere to the protective screen. If it is manually disassembled and cleaned, the operation is cumbersome and the efficiency needs to be improved.
[0004] Therefore, it is necessary to propose a fluidized bed with a dust removal mechanism for sulfasalazine to solve the above problems. Utility Model Content

[0021] This utility model provides, for example Figures 1-3 The fluidized bed of sulfasalazine with a dust removal mechanism shown includes a fluidized bed body 1, a feed pipe 3 for feeding sulfasalazine, an exhaust pipe 2 for exhausting gas, and internal structures such as heating equipment and gas distribution pipes (not shown in the figure) for processing sulfasalazine. The heating equipment includes structures such as electric heating wires to heat the gas. The fluidized bed and its working principle are common existing technologies and will not be described in detail here.
[0022] The side of the fluidized bed body 1 is connected to an air inlet box 4. A filter screen 5 is slidably installed inside the air inlet box 4. A fan 6 is installed inside the air inlet box 4, and the fan 6 is located on the side of the filter screen 5 close to the fluidized bed body 1. The fan 6 is equipped with a built-in motor, fan blades and other structures. The air inlet box 4 is equipped with a power supply device to power the fan 6, including a battery and other structures.
[0023] Specifically, when using a fluidized bed to treat sulfasalazine, the fan 6 operates to draw outside air into the air intake box 4, where impurities are filtered out by the filter screen 5 and then heated by the heating equipment before entering the fluidized bed body 1.
[0024] Considering that dust and other impurities are easily attached to the filter screen 5, a rotating bar 9 is provided on the side of the filter screen 5 facing away from the fluidized bed body 1 in order to clean the dust and other impurities.
[0025] An elastic component is provided on the side of the filter screen 5 near the fluidized bed body 1. The elastic component includes a support block 14 and an elastic telescopic rod 15. The support block 14 is fixedly connected to the inner wall of the air inlet box 4, and the fixed end of the elastic telescopic rod 15 is fixedly connected to the support block 14. The filter screen 5 is fixedly connected to the telescopic end of the elastic telescopic rod 15. With the support block 14 and the elastic telescopic rod 15, when the rotating bar 9 squeezes the filter screen 5, the elastic telescopic rod 15 retracts. After the rotating bar 9 disengages from the filter screen 5, the restoring force of the elastic telescopic rod 15 causes the filter screen 5 to return to its original position, thereby allowing the filter screen 5 to swing back and forth.
[0026] A motor 7 is fixedly connected to the top of the air intake box 4. A through slot is provided on the air intake box 4 through which the drive shaft of the motor 7 passes. The fan 6 is fixedly connected to the drive shaft of the motor 7. Specifically, when treating sulfasalazine using a fluidized bed, external air is drawn into the air intake box 4 by the fan 6. When the filter screen 5 needs to be cleaned, the motor 7 drives the fan 6 to rotate 180°, and the exhaust pipe 2 draws in external gas and backflushs the filter screen 5 to remove impurities.
[0027] Motor 7 is also powered by a power supply device.
[0028] During the above process, the operator places a movable filter plate at the end of the exhaust pipe 2 to prevent impurities from entering the interior of the fluidized bed body 1.
[0029] Meanwhile, the blown-off impurities fall to the ground and can be removed by operators using vacuum cleaners.
[0030] After cleaning, motor 7 drives fan 6 to rotate 180° in the opposite direction to reset.
[0031] A transmission assembly is provided between the fan 6 and the rotating bar 9. The transmission assembly includes a first rotating shaft 8, a first pulley 10, a second rotating shaft 11, a second pulley 12, and a belt 13. The first rotating shaft 8 is rotatably mounted at the bottom of the air intake box 4, and the top of the first rotating shaft 8 is fixedly connected to the fan 6. The first pulley 10 is fixedly connected to the bottom of the first rotating shaft 8. The second rotating shaft 11 is rotatably connected to the bottom of the air intake box 4. The rotating bar 9 is fixedly connected to the top of the second rotating shaft 11, and the second pulley 12 is fixedly connected to the bottom of the second rotating shaft 11. The first pulley 10 and the second pulley 12 are connected by the belt 13. The size of the first pulley 10 is larger than the size of the second pulley 12. When the first pulley 10 rotates half a turn, the second pulley 12 rotates three turns or more.
[0032] During the process of the motor 7 driving the fan 6 to rotate 180°, the fan 6 drives the first pulley 10 to rotate through the first shaft 8. Since the first pulley 10 and the second pulley 12 are connected by the belt 13, the second pulley 12 drives the rotating bar 9 to rotate through the second shaft 11. The rotating bar 9 strikes the filter screen 5, making the impurities loose and easier to blow away later.
[0033] This utility model uses a structure including a fan 6, a rotating bar 9, and a transmission assembly to back-blow the filter screen 5, thereby cleaning impurities. At the same time, the rotating bar 9 strikes the filter screen 5, loosening the impurities, ensuring dust removal effect, and improving the utilization efficiency of the sulfasalazine fluidized bed.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
