[0013] Preferably, the positions and sizes of the first dust cleaning columns are the same as those of the filter holes on the second filter plate, and the positions and sizes of the second dust cleaning columns are the same as those of the filter holes on the first filter plate.

[0014] Preferably, an air inlet communicated with the filter box is fixedly connected to one side of the dust removal box, a dust extractor is fixedly connected to the bottom of the filter box, an ash discharge pipe extending through the outside of the dust removal box is fixedly connected to the output end of the dust extractor, four second support columns are fixedly connected inside the dust removal box, a water mist box communicated with the air guide pipe is fixedly connected to the tops of the four second support columns, a sewage discharge pipe extending through the outside of the dust removal box is fixedly connected to the bottom of the water mist box, a dryer is fixedly connected to one side of the water mist box through a pipeline, and an exhaust pipe extending to the outside of the sealing cover is fixedly connected to the top of the dryer.

This initial screening process not only reduces the burden of subsequent dust removal procedures, but also significantly improves the overall dust removal efficiency and ensures the cleanliness of the indoor air.

[0018] 2. By setting up a cleaning component, the first reciprocating screw fixedly connected to the first rotating shaft can be driven to rotate. At this time, the second filter plate makes reciprocating linear motion along the guide rod on the first reciprocating screw. The first cleaning column can penetrate into the filter holes of the first filter plate to effectively pound out the dust particles deposited therein. At the same time, the second cleaning column also performs the same detailed cleaning on the filter holes of the second filter plate, ensuring that the filter holes will not be blocked due to dust accumulation, and always maintaining good filtering performance. It can not only operate stably and efficiently for a long time, but also does not require frequent manual maintenance, greatly reducing maintenance costs.

[0019] 3. By setting up a scraping assembly, when the rotating disk rotates, the cleaning scraper first scrapes and cleans the dust on the inner wall of the air duct, and the first gear drives the second gear to rotate synchronously, and the second gear is connected to the synchronous shaft through a synchronous belt, so that the two synchronous shafts also rotate synchronously, and the second reciprocating screw is driven by the synchronous belt to rotate in the slide groove, pushing the ash pushing plate threadedly connected to it to slide along the slide groove, and the ash pushing plate pushes the scraped dust further along the inner wall of the pipe, so that it will not continue to remain inside the pipe, thereby preventing the occurrence of pipe blockage and ensuring that the entire self-circulating dust removal chamber can operate normally and stably.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Embodiment 1:

[0033] Referring to Figures 1-5 and Figure 10 , an environmentally friendly engineering self-circulating dust removal chamber includes a dust removal component, a filtering component and a cleaning and scraping component;

[0034] The dust removal component is used to clean and remove dust in the air. The dust removal component includes a dust removal box 1 and a sealing cover 2 fixedly connected to the top of the dust removal box 1;

[0035] The filtering component is used to initially filter and remove large-volume impurities in the air. The filtering component includes a filter box 5 fixedly connected inside the dust removal box 1 and a fixed frame 14 fixedly connected inside the filter box 5;

[0036] The scraping assembly is used to scrape away the dust adhered and condensed on the inner wall of the pipeline to prevent clogging. The scraping assembly includes an air guide pipe 8 fixedly connected to one side of the filter box 5 and a second fixing plate 26 fixedly connected to one side of the air guide pipe 8;

[0037] A motor 15 is fixedly arranged on the fixed frame 14, a fan 16 is fixedly connected to the driving end of the motor 15, a first filter plate 17 is fixedly connected inside the filter box 5, a first rotating shaft 18 rotatably connected to the first filter plate 17 is fixedly connected to one side of the fan 16, a cleaning brush 19 is fixedly connected to the first rotating shaft 18, and a cleaning component for pounding out and cleaning the dust deposited inside the filter holes of the first filter plate 17 is arranged on one side of the first filter plate 17;

[0038] The cleaning assembly includes a guide rod 20 fixedly connected to the bottom of the filter box 5, a first fixed plate 21 is fixedly connected to the side of the filter box 5 away from the fixed frame 14, a first reciprocating screw 22 fixedly connected to the first rotating shaft 18 is rotatably connected to the first filter plate 17, a second filter plate 23 is threadedly sleeved on the first reciprocating screw 22 and is slidably connected to the guide rod 20, a first filter plate 17 is fixedly connected to a side close to the second filter plate 23 with a plurality of first cleaning columns 24, and a second filter plate 23 is fixedly connected to a side close to the first filter plate 17 with a plurality of second cleaning columns 25;

[0039] The position and size of the first cleaning column 24 are consistent with the position and size of the filter holes on the second filter plate 23, and the position and size of the second cleaning column 25 are consistent with the position and size of the filter holes on the first filter plate 17;

[0040] In this embodiment, when the motor 15 is started, the fan 16 rotates at a high speed, forming a strong and continuous airflow inside the filter box 5. Under the action of the airflow, large-volume impurities in the air are quickly guided to the first filter plate 17. The first filter plate 17 is fixed in the filter box 5. The filter holes opened thereon can intercept large-volume impurities, complete the initial high-efficiency filtration of the air, and reduce the burden of the subsequent dust removal process.

[0041] Furthermore, when the motor 15 drives the fan 16 to rotate, the first rotating shaft 18 fixedly connected to one side of the fan 16 rotates synchronously, and the first rotating shaft 18 drives the first reciprocating screw 22 fixedly connected thereto to rotate. Under the precise guidance of the guide rod 20, the second filter plate 23 makes reciprocating linear motion along the guide rod 20 on the first reciprocating screw 22. When the second filter plate 23 makes reciprocating linear motion, the first cleaning column 24 penetrates into the filter holes of the first filter plate 17 to pound out the dust particles deposited therein. At the same time, the second cleaning column 25 cleans the filter holes of the second filter plate 23 to ensure that the filter holes will not be blocked due to dust accumulation, thereby maintaining long-term and efficient operation of the filter assembly.

[0042] Embodiment 2:

[0043] Referring to Figures 6-9 , compared with Embodiment 1, in this embodiment, a rotating disk 27 is rotatably connected to one side of the second fixing plate 26. A second rotating shaft 28 rotatably connected to the first fixing plate 21 is fixedly connected to one side of the rotating disk 27. The second rotating shaft 28 is fixedly connected to the first reciprocating lead screw 22. A first gear 29 fixedly connected to the second fixing plate 26 is arranged inside the rotating disk 27. Two second gears 30 rotatably connected to the rotating disk 27 are arranged on both sides of the first gear 29. Two synchronizing shafts 31 are rotatably connected inside the rotating disk 27. The two second gears 30 and the two synchronizing shafts 31 are connected by a timing belt 32. Two cleaning scrapers 33 are fixedly connected to the side of the rotating disk 27 away from the second fixing plate 26. Chute grooves 34 are formed in the two cleaning scrapers 33. Second reciprocating lead screws 35 are rotatably connected inside the two chute grooves 34. Pushing ash plates 36 slidably connected to the chute grooves 34 are sleeved on the second reciprocating lead screws 35.

[0044] The first gear 29 meshes with the two second gears 30 on both sides respectively.

[0045] In this embodiment, when the second rotating shaft 28 drives the rotating disk 27 to rotate, the first gear 29 drives the second gears 30 to rotate synchronously. The second gears 30 and the synchronizing shafts 31 are connected by the timing belt 32, so that the two synchronizing shafts 31 rotate synchronously, thereby ensuring that the cleaning scraper 33 fixed to the side of the rotating disk 27 away from the second fixing plate 26 can perform scraping operations on the inner wall of the pipeline stably and efficiently, ensuring that the cleaning scraper 33 fixed to the side of the rotating disk 27 away from the second fixing plate 26 can perform scraping operations on the inner wall of the pipeline in a stable and efficient manner. In actual operation, no matter how the airflow in the pipeline changes, the cleaning scraper 33 can always maintain a stable scraping action, timely remove the dust adhering to the inner wall of the pipeline, prevent dust accumulation from forming blockages, ensure the smoothness of the pipeline system such as the air guide pipe 8, and provide a reliable guarantee for the continuous, stable and normal operation of the entire self-circulating dust removal chamber.

[0046] Further, after the cleaning squeegee 33 scrapes the inner wall of the pipeline, the second reciprocating lead screw 35 rotates to push the ash pushing plate 36 to slide along the chute 34. The ash pushing plate 36 further pushes the scraped dust along the inner wall of the pipeline, preventing the dust from adhering and condensing on the inner wall of the pipeline. It can not only scrape the dust on the inner wall of the pipeline, but also completely clean the scraped dust out of the pipeline, fundamentally eliminating the possibility of pipeline blockage caused by dust accumulation. For example, in some industrial production environments where sticky dust is easily generated, ordinary dust cleaning methods can only scrape the dust off, but cannot effectively clean it, resulting in the dust quickly adhering again and blocking the pipeline. However, the ash pushing plate 36 in this design can completely remove the dust, ensuring that the pipeline system is unobstructed for a long time and guaranteeing the stable operation of the entire self-circulating dust removal chamber.

[0047] In addition, the shape and size of the ash pushing plate 36 are optimized according to the actual situation of the inner wall of the pipeline, and it can closely fit the inner wall of the pipeline to completely clean the dust. The threaded connection between the second reciprocating lead screw 35 and the ash pushing plate 36 is carefully calculated to ensure that when the second reciprocating lead screw 35 rotates, the ash pushing plate 36 can slide smoothly and accurately. The surface of the chute 34 is polished to reduce the frictional resistance when the ash pushing plate 36 slides, improving the cleaning efficiency.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
