[0002] A dryer refers to a mechanical device that uses heat energy to reduce the moisture content of materials and is used for drying objects. Currently, during the production of starch, a large amount of tail gas is generated after the tube bundle dryer dries the materials. If the tail gas is directly discharged into the air, it is easy to cause environmental pollution and affect people's living health. Therefore, the treatment of tail gas dust is particularly important. Reducing the potential safety hazard of stored materials in the pipeline has always been the most difficult problem to solve in the starch production process. When removing dust from the dried tail gas, generally a cyclone dust removal device is used for dust removal treatment, which is a key process in the corn starch production process and can effectively reduce the dust content in the tail gas and reduce air pollution.

[0003] The specification of Chinese Patent CN217526867U discloses a tail gas dust removal device for a large dryer, including a housing, a primary spraying assembly, a first-stage adsorption packing layer, a cooling assembly, a second-stage adsorption packing layer, a dust removal washing assembly, and a demister; the housing is of a vertical structure, with legs provided at the lower part of the housing, a water outlet provided at the bottom of the housing, an air outlet provided at the top, and a tail gas inlet further provided on the outer edge of the lower part; the primary spraying assembly is arranged above the tail gas inlet of the housing; the first-stage adsorption packing layer, the cooling assembly, the second-stage adsorption packing layer, the dust removal washing assembly, and the demister are sequentially arranged in the housing from bottom to top.

[0024] The following will make a detailed description of two implementation manners of the present application in conjunction with the accompanying drawings.

[0025] The first implementation manner:

[0026] Figures 1-5 An efficient dust removal device for the tail gas of a dryer is shown, including a dust removal machine body 1. A discharge port 2 is drilled at the bottom end of the dust removal machine body 1. A connecting pipe 3 is threadedly connected to the bottom end of the discharge port 2. A dust storage box 4 is provided at the bottom end of the connecting pipe 3. A connection port 8 is drilled at the top end of the dust storage box 4, and the connection port 8 is threadedly connected to the connecting pipe 3. A sealing ring 7 is sleeved between the connection port 8 and the connecting pipe 3. A drawer 5 is slidably connected to the side end of the dust storage box 4. An annular chute 9 is fixedly connected to the inner top wall of the dust storage box 4 outside the connection port 8. An electric slide rail 12 is fixedly connected to the annular chute 9. A short brush 10 is slidably connected to the electric slide rail 12. A slider 11 is slidably connected to the electric slide rail 12. A first card slot 14 is drilled at one end of the slider 11 away from the electric slide rail 12. A first card block 16 is fixedly connected to one end of the short brush 10 close to the slider 11, and the first card block 16 is engaged with the first card slot 14 and is threadedly fixed by a first bolt 15. The top end of the short brush 10 is detachably connected to a long brush 13. A second card slot is drilled at the top end of the short brush 10. A second card block 17 is fixedly connected to the bottom end of the long brush 13, and the second card block 17 is engaged with the second card slot and is threadedly fixed by a second bolt. The short brush 10 and the long brush 13 respectively abut against the inner walls of the connection port 8 and the connecting pipe 3. The drawer 5 is located below the bottom end of the slider 11.

[0027] This solution can achieve that when using the dust removal machine body 1 to remove dust from the tail gas of the dryer, a connecting pipe 3 with a matching length can be selected first, and the two ends are respectively threadedly fixed to the discharge port 2 and the connection port 8, and the sealing performance is increased through the sealing ring 7. Then, the second card block 17 is inserted into the second card slot and threadedly fixed by the second bolt, so as to splice the long brush 13 and the short brush 10. At this time, the drawer 5 is pulled out, and the short brush 10 and the long brush 13 are inserted into the connecting pipe 3 through the connection port 8 from the side end of the dust storage box 4. Then, the first card block 16 is inserted into the first card slot 14 and threadedly fixed by the first bolt 15. At this time, the long brush 13 abuts against the inner wall of the connecting pipe 3, and the short brush 10 abuts against the inner wall of the connection port 8. The drawer 5 is inserted into the dust storage box 4, and the dust removal machine body 1 is turned on to perform tail gas dust removal. At the same time, the electric slide rail 12 is turned on to drive the short brush 10 and the long brush 13 to rotate and wipe the inner wall of the connecting pipe 3, and the dust particles generated after the treatment of the dust removal machine body 1 are scraped from the connecting pipe 3 into the drawer 5 for collection, effectively achieving the effect of avoiding the adhesion of dust particles to the inner wall of the connecting pipe 3 and causing blockage, and at the same time cleaning the inner wall of the connecting pipe 3.

[0028] The second implementation manner:

[0029] Figure 1 and Figures 6-7It is shown that a notch is provided on the inner wall of the drawer 5 close to one side of the ash storage box 4. A baffle 18 is rotatably connected to the inner wall of the notch through a second rotating shaft. Magnets 20 are embedded and installed on both the surface of the baffle 18 close to the notch of the drawer 5 and the surface of the baffle 18 close to the notch. The two magnets 20 attract each other. A steel cable 19 extending outside the drawer 5 is fixedly connected to the lower part of the baffle 18 close to the drawer 5. One end of the drawer 5 far from the ash storage box 4 is rotatably connected to a first rotating shaft 21, and the steel cable 19 is wound around the surface of the first rotating shaft 21. A screwing shaft 6 is fixedly connected to the side end of the first rotating shaft 21. Corresponding rectangular slots 22 are drilled on both the end of the screwing shaft 6 far from the first rotating shaft 21 and the drawer 5 directly above. A U-shaped rod 23 is inserted into the rectangular slot 22.

[0030] This solution can achieve that when the dust collector body 1 is enabled, the U-shaped rod 23 can be pulled out of the rectangular slot 22, and then the screwing shaft 6 is held by hand to rotate the first rotating shaft 21 to drive the steel cable 19 to rotate, pulling the baffle 18 to abut against the cross-section of the drawer 5. At this time, the U-shaped rod 23 is inserted into the rectangular slot 22 to position the screwing shaft 6, thereby fixing the position of the baffle 18. At the same time, the baffle 18 and the cross-section of the drawer 5 are attracted to each other by the magnets 20 for reinforcement. At this time, the drawer 5 can be inserted into the ash storage box 4 for dust collection. When it is full and needs to be cleaned, the drawer 5 can be pulled out and the U-shaped rod 23 can be removed. At this time, the magnets 20 on the baffle 18 and the notch of the drawer 5 can be separated, so as to open the baffle 18, so that the internal dust can be poured out obliquely, avoiding the need to turn the drawer 5 over to pour out the dust, resulting in a dust-raising effect.

[0031] Combined with the current actual requirements, the above implementation manner adopted in this application, the protection scope is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
