Therefore, it is necessary to use existing dust collection equipment such as bag filters and cyclone dust collectors for dust removal.

[0003] Baghouse dust collectors are commonly used, but the filter bags used in baghouse dust collectors are prone to clogging, resulting in high maintenance costs and the need for frequent maintenance and cleaning, which in turn affects the dust removal efficiency. Therefore, a high-efficiency dust collector is needed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0024] Please see Figures 1-4 In this utility model, a high-efficiency dust collector for a continuous dryer includes an exhaust pipe 1. A processing cylinder 2 is fixedly connected to the right end of the exhaust pipe 1. A conduit 3 connects to the right side of the processing cylinder 2, and a filter barrel 4 connects to the right end of the conduit 3. An exhaust pipe 5 connects to the right side of the filter barrel 4. A filter bag 6 is fixedly connected to the inner top wall of the filter barrel 4, and a fixing ring 7 is fixedly connected to the bottom of the filter bag 6. The outer side of the fixing ring 7 is fixedly connected to the filter barrel 4. A sealing mechanism 8 is provided between the processing cylinder 2 and the filter barrel 4. A rotating rod 9 is rotatably connected to the inner wall of the processing cylinder 2, and two filter plates 10 are fixedly connected to the rotating rod 9. Two through holes 11 are opened on the left side of the processing cylinder 2, and adjusting blocks 12 are threadedly connected to the inner walls of both through holes 11. Springs 13 are fixedly connected to the right side of the adjusting block 12. Contact blocks 14 are fixedly connected to the right ends of the two springs 13. The right sides of the two contact blocks 14 are hemispherical. Motor 15 is fixedly connected to the top of the processing cylinder 2. The output shaft of motor 15 is fixedly connected to the rotating rod 9. The sealing mechanism 8 includes a connecting block 801. The left and right sides of the connecting block 801 are fixedly connected to the processing cylinder 2 and the filter barrel 4, respectively. An electric push rod 802 is inserted through the connecting block 801 and fixedly connected to it. A lifting block 803 is fixedly connected to the bottom end of the electric push rod 802. Sealing plates 804 are fixedly connected to the left and right sides of the lifting block 803. The tops of the two sealing plates 804 are in contact with the inner walls of the processing cylinder 2 and the filter barrel 4, respectively.

[0025] In this invention, the exhaust gas generated in the continuous dryer first enters the treatment cylinder 2 through the exhaust pipe 1, then enters the filter barrel 4 through the conduit 3, and then flows into the filter bag 6. As the exhaust gas passes through the filter bag 6, the dust in the exhaust gas is filtered out. Finally, the exhaust gas is discharged from the exhaust pipe 5, thus achieving the dust removal effect on the exhaust gas generated by the continuous dryer. Before entering the filter bag 6, the exhaust gas first passes through the filter barrel 4. During this process, the user turns on the motor 15, which drives the rotating rod 9 to rotate. After the rotating rod 9 rotates, it drives the filter plate 10 to rotate. After the filter plate 10 rotates, it captures large dust particles in the exhaust gas, thereby achieving the effect of filtering large particles in the exhaust gas. Large particles in the air are filtered before entering the filter bag 6, which can effectively reduce the clogging of the filter bag 6, improve the filtration effect of fine dust, and reduce the clogging of the filter bag 6, thereby improving the dust removal efficiency.

[0026] When cleaning is required after a period of use, the user activates the electric push rod 802, which causes the lifting block 803 to descend. Then, the lifting block 803 causes the sealing plate 804 to descend. After the sealing plate 804 descends, it loses its seal on the processing cylinder 2 and the filter barrel 4. At this time, the user can clean the filter bag 6 and the filter plate 10. During the cleaning process, the user first rotates the adjusting block 12, which moves along the inner wall of the through hole 11. During this process, the right side of the contact block 14 will enter the processing cylinder 2. At this time, the user activates the motor 15 to rotate the filter plate 10. The rotating filter plate 10 will continuously slide over the hemispherical part of the contact block 14. Each time it slides over, the filter plate 10 will be impacted. Each impact will cause the filter plate 10 to vibrate. The vibration will shake off the large particles attached to the surface of the filter plate 10, thereby achieving the cleaning effect of the filter plate 10 and effectively reducing the cleaning difficulty.

[0027] Please see Figure 3 The sealing plate 804 has an annular groove 16, and a sealing ring 17 is fixedly connected to the inner wall of the annular groove 16. The annular groove 16 is positioned in the position of the sealing ring 17, which can improve the sealing effect of the sealing plate 804.

[0028] Please see Figure 3 The filter barrel 4 is rotatably connected to a vertical rod 18. A motor 2 19 is fixedly connected to the top of the filter barrel 4. The output shaft of the motor 2 19 passes through the filter barrel 4 and is fixedly connected to the vertical rod 18. Two vertical plates 20 are fixedly connected to the vertical rod 18. Two cleaning brushes 21 are fixedly connected to the outer side of the two vertical plates 20. The opposite sides of the two cleaning brushes 21 are in contact with the filter bag 6.

[0029] In this invention, during the cleaning and maintenance process, the user turns on the motor 19, which drives the vertical rod 18 to rotate. After the vertical rod 18 rotates, it drives the cleaning brush 21 to slide along the filter bag 6 through the vertical plate 20, thereby sweeping away the dust on the surface of the filter bag 6 and achieving the effect of automatic cleaning of the filter bag 6.

[0030] Please see Figure 1 Among them, a controller 22 is installed on the front of the treatment cylinder 2, and a flow sensor 23 is installed on the exhaust pipe 5.

[0031] In this invention, the flow sensor 23 can monitor the flow rate of gas discharged from the exhaust pipe 5. When the gas flow rate decreases, it indicates that the filter bag 6 is clogged, and the equipment needs to be cleaned and maintained to improve the practicality of the device.

[0032] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
