[0021] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions based on the principles of the present invention should be included in the scope of protection of the present invention. It should also be noted that improvements and modifications that do not depart from the principles of the present invention by ordinary skill in the art should also be considered within the scope of protection of the present invention.
[0022] As shown in the figure, a high-temperature resistant solid-gas filtering device includes a filter cartridge 1, the bottom of which is connected to an air inlet pipe 2. The top of the filter cartridge 1 is fixedly connected to an exhaust pipe 9.
[0023] The filter cartridge 1 has an air intake structure at its base, consisting of a support frame 3, an air inlet 4, a fixed port 5, and a protective cover. The air inlet 4 is located at the base of the filter cartridge 1, connected to the support frame 3. The support frame 3 is hollow and truncated, while the fixed port 5 is Y-shaped. The bottom of the fixed port 5 is connected to the air inlet pipe 2, with both ends of the Y connected to the hollow truncated cone. The protective cover is connected to the support frame 3, with both ends of the Y located within the protective cover. A connecting thread is provided on the inside of the vertical section of the air inlet 4, while a fixed thread is provided on the outside of the top of the air inlet pipe 2. These connecting threads are threadedly connected to the fixed thread. High-temperature exhaust gas enters the fixed port 5 from the air inlet pipe 2 and is discharged into the filter cartridge 1 from both ends of the Y-shape.
[0024] A screen is fixedly connected to the center of the filter cartridge 1. The screen comprises a filter screen 6 and a filter cloth 7. The filter screen 6 is fixedly connected to the filter cloth 7. The filter screen 6 is fixedly connected to the filter cartridge 1 near the air inlet 4. The upper surface of the filter cloth 7 is provided with fine mesh. A chute 10 is provided on the upper surface of the filter cloth 7. A rolling ball 11 is slidably connected within the chute 10. The surface of the rolling ball 11 is perforated with ventilation holes. The exhaust gas entering the filter cartridge 1 is screened by the screen. Solids are filtered by the filter screen 6 and remain in the filter screen 6. The exhaust gas is then filtered by the filter screen 6 and the filter cloth 7 and discharged from the exhaust pipe 9. After cooling, the remaining solids fall outside the support frame 3 and the protective cover.
[0025] A cleaning groove is provided at the bottom of the filter cartridge 1, in which a sealing plate 8 is slidably connected. The sealing plate 8 is L-shaped. The sealing plate 8 is removed from the cleaning groove to clean the residual solids accumulated at the bottom of the filter cartridge 1.
[0026] Working principle: High-temperature exhaust gas enters the fixed port 5 from the air inlet pipe 2 and is discharged into the filter cartridge 1 from both ends of the Y-shape. The exhaust gas entering the filter cartridge 1 is screened by the screen. The solids are filtered by the filter screen 6 and remain in the filter screen 6. The exhaust gas is filtered by the filter screen 6 and the filter cloth 7 and discharged from the exhaust pipe 9. After cooling, the residual solids fall outside the support frame 3 and the protective cover. After removing the sealing plate 8 from the cleaning tank, clean the residual solids accumulated at the bottom of the filter cartridge 1. During the exhaust gas filtration process, the exhaust gas drives the rolling ball 11 to move in the chute 10, shaking off the residual solids attached to the bottom of the screen.
[0027] To sum up, the high-temperature gas enters the filter cartridge 1 through the air inlet pipe 2, and the fixed port 5 ejects the high-temperature gas from both sides. The high-temperature gas is screened by the screen and the cooled gas is discharged. It is fixed and falls from the screen to the bottom of the filter cartridge 1, and the filter cartridge 1 is cleaned from the cleaning tank.
