Description

Technical Field

[0001] This utility model relates to a pneumatic ash conveying pipe with a detachable filter plate. Background Technology

[0002] In the field of industrial production, pneumatic ash conveying technology is widely used in the dust material conveying process of industries such as power, metallurgy, and chemical industry due to its advantages such as high conveying efficiency, small footprint, and easy automation control.

[0003] However, during the ash conveying process, the dust material often carries some larger particles, foreign objects, or hard impurities. Driven by the high-speed airflow, these particles continuously scour and impact the inner wall of the pneumatic ash conveying pipeline, which not only accelerates the wear and aging of the pipeline, shortens its service life, and increases maintenance costs, but may also accumulate at pipe bends, diameter changes, and other parts, causing blockages and affecting the stable operation of the conveying system.

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-7 As shown, the pneumatic ash conveying pipeline with detachable filter plates provided in this embodiment includes a pipeline body 1, a filter plate 2 is provided inside the pipeline body 1, filter residue collection troughs 3 are provided on both sides of the bottom of the filter plate 2, a filter plate insertion port 4 is provided at the bottom of the pipeline body 1, filter residue collection trough interface 5 is provided on both sides of the filter plate insertion port 4, a first flange 6 is provided on the outer edge of the filter residue collection trough 3, and a second flange 7 is provided on the inner edge of the filter residue collection trough interface 5. The first flange 6 and the second flange 7 are fixedly connected by bolts.

[0025] Filter plate 2 can filter large particulate impurities in dusty materials, reduce the impact on the pipe body 1, and reduce the accumulation and blockage at bends, diameter changes, and other parts of the pipe body 1.

[0026] The filter residue collection tank 3 can hold the impurities after filtration. When cleaning is required, it is removed together with the filter plate 2 to remove the fallen impurities.

[0027] The filter plate insertion port 4, the first flange 6, and the second flange 7 enable the filter plate 2 to be detachable, facilitating regular removal for cleaning or replacement.

[0028] In this embodiment, as Figure 1 As shown, both the first flange 6 and the second flange 7 are semi-circular structures, which, combined with the shape design of the filter plate insertion port 4, facilitate disassembly.

[0029] In this embodiment, as Figure 1 As shown, a first reinforcing plate 8 is provided between the top surfaces of the two first flanges 6, and a second reinforcing plate 9 is provided between the top surfaces of the two second flanges 7. The first reinforcing plate 8 and the second reinforcing plate 9 are fixedly connected by bolts. The first reinforcing plate 8 and the second reinforcing plate 9 connect the two sides of the first flanges 6 and the second flanges 7 to form a stable frame structure, which further improves the connection strength and sealing of the interface between the filter residue collection tank 3 and the pipe body 1, and prevents ash leakage or detachment after long-term use.

[0030] In this embodiment, as Figure 7 As shown, the filter plate 2 includes a filter screen 201 and a filter frame 202 surrounding the filter screen 201. A filter frame insertion slot 10 is provided on the pipe body 1 directly above the filter plate insertion port 4. The filter frame insertion slot 10 provides installation space for the filter frame 202, ensuring that the filter screen 201 occupies the entire space of the pipe body 1 and maximizing the filtration area.

[0031] In this embodiment, as Figure 3As shown, the diameter of the filter screen 201 is the same as the inner diameter of the pipe body 1, and the depth of the filter frame insertion groove 10 is the same as the thickness of the filter frame 202, so that the filter screen 201 completely covers the cross-section of the pipe body 1, achieving full-section filtration without any dead angles.

[0032] In this embodiment, as Figure 1 As shown, a stud 11 is vertically installed on the top of the filter frame 202. A through hole 12 is provided on the filter frame insertion groove 10 for the stud 11 to pass through. A nut 13 is provided on the stud 11 and is fixed on both the upper and lower sides of the filter plate 2 to improve the fixing effect. The corresponding positions of the stud 11 and the through hole 12 can also play a positioning role. When disassembling, the filter plate 2 can also be moved downward by tapping the stud 11 and detached from the pipe body 1.

[0033] In this embodiment, as Figure 1 As shown, a nut fastening boss 14 is provided on the top surface of the filter frame insertion groove 10. The through hole 12 passes through the nut fastening boss 14. The top surface of the nut fastening boss 14 is flat, which can better cooperate with the nut 13 and improve the fixing effect.

[0034] In summary, in this embodiment, the filter plate 2 can intercept impurities in the dust material, preventing impurities from continuously scouring and impacting the inner wall of the pipe body 1, thereby extending the service life of the pipe body 1 and ensuring the stable operation of the ash conveying system. The filter residue collection tank 3 can promptly collect the filtered impurities and can be removed along with the filter plate 2 for periodic cleaning, effectively preventing impurities from accumulating and causing blockage of the pipe body 1. The filter plate 2 is detachably connected through the filter plate insertion port 4 and the flange, facilitating periodic removal for cleaning or replacement without the need for complete disassembly of the pipe body 1, reducing maintenance difficulty and cost, and improving maintenance efficiency.

[0035] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
