DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0031] Please refer to Figures 1-12 The present application provides a technical solution: a self-cleaning smoke dust collecting device, which comprises a filter assembly 1 and a cleaning assembly 2. The filter assembly 1 comprises an assembly plate 11, an exhaust pipe 12 and an annular filter screen 13. The cleaning assembly 2 comprises a first conveying pipe 21 and several second conveying pipes 22. The second conveying pipes 22 are provided with several through holes 221. In use, the filter assembly 1 and the cleaning assembly 2 are installed inside a collection box 3, and the exhaust pipe 12 and the first conveying pipe 21 extend to the outside of the top of the collection box 3. The exhaust pipe 12 is connected to the air inlet end of an external exhaust device (such as an exhaust pump), and an air inlet pipe 31 on the side wall of the collection box 3 is connected to a pipe for discharging smoke dust. When smoke dust generated by burning coal enters the inside of the collection box 3, the exhaust device works, and the air in the inside of the collection box 3 is filtered by the annular filter screen 13 and then enters the exhaust pipe 12 to be exhausted, and the smoke dust in the inside of the collection box 3 stays on the annular filter screen 13.

[0032] When the annular filter screen 13 needs to be cleaned, the first conveying pipe 21 is connected with the water outlet of an external water source (such as a water pump), and the water enters the first conveying pipe 21, then enters the second conveying pipes 22, and is sprayed to the annular filter screen 13 through the through holes 221, thereby completing the cleaning operation of the annular filter screen 13. Subsequently, the smoke dust and sewage fall to the bottom of the collecting box 3, and finally enter the discharge pipe 32 at the bottom of the collecting box 3 to leave the collecting box 3. The discharge pipe 32 can be connected with an external collecting device (such as a sewage collecting box) to collect the washed smoke dust. The collected smoke dust can be recycled as cement, concrete admixture or roadbed material, etc., to realize resource utilization and reduce waste discharge. Since the annular filter screen 13 separates the second conveying pipes 22 from the smoke dust, the smoke dust neither causes the blockage of the through holes 221 nor causes the wear of the second conveying pipes 22, thereby prolonging the service life of the present application.

[0033] Embodiment one

[0034] Please refer to Figures 1-8 The cleaning assembly 2 further comprises a first connecting block 23 and a second connecting block 24. The first connecting block 23 is internally provided with a conveying passage 231, and the second connecting block 24 is sleeved at the bottom of the first connecting block 23. The second conveying pipes 22 are connected with the second connecting block 24, and the inner side wall of the second connecting block 24 is provided with a groove 241. After entering the first conveying pipe 21, the water can enter the conveying passage 231, and then enter the groove 241 through the conveying passage 231. The water can apply pressure to the inner wall of the groove 241 to drive the second connecting block 24 to rotate at the bottom of the first connecting block 23. In this process, the second connecting block 24 drives the second conveying pipes 22 to rotate together, so that the water sprayed through the through holes 221 can cover the entire annular filter screen 13, thereby improving the cleaning effect.

[0035] Please refer to Figures 1-8 The conveying passage 231 comprises a first passage 2311 and a plurality of second passages 2312. The water in the first conveying pipe 21 first enters the first passage 2311, and then enters the plurality of second passages 2312, respectively, and then leaves the interior of the first connecting block 23 through the openings on the side wall of the first connecting block 23. The present application ensures that no matter where the groove 241 moves, there is always a first passage 2311 to send water into the groove 241. The groove 241 also has a plurality of second passages 2312 in a C-shaped structure. The water leaving the interior of the first connecting block 23 can enter the plurality of grooves 241, respectively, and the second connecting block 24 is uniformly stressed, so that the second connecting block 24 can stably rotate.

[0036] Please refer to Figures 1-12The bottom of the second connecting block 24 is provided with a third conveying pipe 25, and the inside of the second connecting block 24 is provided with a plurality of third channels 242. When water enters the plurality of grooves 241 and drives the second connecting block 24 to rotate, the water in the plurality of grooves 241 can enter the third conveying pipe 25 together through the plurality of third channels 242, and then enter the plurality of second conveying pipes 22 through the third conveying pipe 25. The second conveying pipe 22 can ensure that water can continuously enter the inside of the second conveying pipe 22 during the rotation of the second connecting block 24, and be sprayed out through the plurality of through holes 221.

[0037] Please refer to Figure 8 、 Figure 10 and Figure 12 , the side wall of the groove 241 is provided with an arc-shaped guide surface 2411, and the depths of the two ends of the groove 241 are different. After the water enters the groove 241, it will first gather at the end with a deeper depth, so that the contact area with the inner side wall of the groove 241 is larger, which can generate a greater thrust. Then the water in the groove 241 can flow to the end with a shallower depth along the arc-shaped guide surface 2411 and enter the inside of the third channel 242.

[0038] Please refer to Figures 1-3 、 Figure 9 and Figures 11-12 , the bottom surface of the second connecting block 24 is provided with an assembly groove 243, and the top of the third conveying pipe 25 is arranged in the assembly groove 243, and there is a gap between the top of the third conveying pipe 25 and the inner top surface of the assembly groove 243. The water in the plurality of third channels 242 can first enter the assembly groove 243 and then enter the third conveying pipe 25. Since the water in the plurality of third channels 242 enters the assembly groove 243 from different directions, the water that has just entered the assembly groove 243 can converge at the gap between the top of the third conveying pipe 25 and the inner top surface of the assembly groove 243, first forming a downward force, and then quickly entering the third conveying pipe 25, thereby increasing the speed and water pressure of the water entering the second conveying pipe 22, and further improving the cleaning effect of the annular filter screen 13.

The second end of the first conveying pipe 21 is connected with the water outlet end of the external water source, and the third end of the first conveying pipe 21 is connected with the air outlet end of the external air source (such as a blower). When the annular filter screen 13 needs to be cleaned, the first electric control valve 26 is opened, and the second electric control valve 27 is closed. Water can enter the plurality of second conveying pipes 22 through the first conveying pipe 21 and be sprayed out through the plurality of through holes 221, so as to clean the annular filter screen 13. When the cleaning work of the annular filter screen 13 is completed, the first electric control valve 26 is closed, and the second electric control valve 27 is opened. The external air first enters the inside of the first connecting block 23 through the first conveying pipe 21, drives the second connecting block 24 to rotate at the same time, and is conveyed to the plurality of second conveying pipes 22. Finally, the plurality of second conveying pipes 22 are rotated at the same time, air is sprayed out through the plurality of through holes 221, the annular filter screen is quickly dried, and the service life of the present application is further prolonged.

[0042] Please refer to Figures 1-12 The filter assembly 1 further comprises an annular ring 14 and a hemispherical filter screen 15. The cleaning assembly 2 is covered inside by assembling the plate 11, the annular filter screen 13, the annular ring 14 and the hemispherical filter screen 15, so that the smoke dust cannot contact the second conveying pipe 22. The cleaning assembly 2 further comprises a conveying disc 28, which is arranged at the bottom of the second conveying pipe 22 and is communicated with the inside of the second conveying pipe 22. The bottom surface of the conveying disc 28 is also provided with a plurality of through holes 221. The water in the second conveying pipe 22 is sprayed out through the through holes 221 in the bottom surface of the conveying disc 28 after entering the conveying disc 28, and the water sprayed out through the conveying disc 28 is used for cleaning the hemispherical filter screen 15.
