DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The following gives specific embodiments.

[0026] Please refer to Figures 1 - 5 , the present invention provides a high-throughput sintered mesh filter element, including a protective outer cylinder 1: a filter mesh cylinder 2 is arranged inside the protective outer cylinder 1; an inner cylinder 6 is arranged inside the filter mesh cylinder 2; a gas guide pipe 12 is fixed at the lower end of the inner cylinder 6; a water outlet 3 is opened at the lower end of the gas guide pipe 12; a connecting column 4 is fixed at the top end of the inner cylinder 6, and the inner side top end of the filter mesh cylinder 2 is attached to the top end of the inner cylinder 6; the protective outer cylinder 1 is connected to the connecting column 4 through a fixing component; a gas guide pipe 12 is arranged inside the connecting column 4; a guiding block 15 is fixed at the lower end of the gas guide pipe 12; a plurality of jet openings 13 are uniformly fixed on the outer side of the guiding block 15; a limiting block 17 is fixed on the outer side of the gas guide pipe 12 located inside the connecting column 4; a limiting component is arranged inside the limiting block 17 for limiting the gas guide pipe 12. During operation, when filtering, the medium to be filtered flows into the inside of the inner cylinder 6 through the filter mesh cylinder 2 and the inner cylinder 6. The filter mesh cylinder 2 can filter out the impurities in the medium, and then discharge them out through the water outlet 3. When cleaning is required, the gas guide pipe 12 is connected to an external air pump, and then the limit of the gas guide pipe 12 is cancelled through the limiting component, so that the gas guide pipe 12 can move up and down, and then the high-pressure gas ejected through the jet openings 13 is used to clean the dust and impurities attached to the outer side of the filter mesh cylinder 2. When disassembly is required, the protective outer cylinder 1 and the filter mesh cylinder 2 can be sequentially taken out from the outside of the inner cylinder 6 through the fixing component to complete the disassembly work. This step can effectively clean the dust and impurities attached to the outer side of the filter mesh cylinder 2 through the high-pressure gas ejected from the jet openings 13 without disassembling the device. At the same time, the limiting component can limit the gas guide pipe 12 to prevent the gas guide pipe 12 from sliding up and down during the operation of the device, effectively improving the cleaning efficiency of the device, reducing the pulling time, and enhancing the practicability of the device;

[0027] Further, as Figure 2 and Figure 3As shown in the figure, the fixing component includes a fixing ring 5; the fixing ring 5 is sleeved on the outer side of the connecting column 4; the fixing ring 5 is slidably connected to the connecting column 4; a plurality of positioning blocks 10 are uniformly fixed on the inner side of the fixing ring 5; a positioning groove 9 is vertically opened at a position corresponding to the positioning block 10 on the connecting column 4; the positioning block 10 is slidably connected to the connecting column 4 through the positioning groove 9; an anti-disengagement groove 11 is opened at a position corresponding to the positioning block 10 on the outer side of the lower end of the connecting column 4; the positioning block 10 is inserted and connected to the connecting column 4 through the anti-disengagement groove 11. During operation, when it is necessary to disassemble the protective outer cylinder 1 and the filter screen cylinder 2, first press down the fixing ring 5 and then rotate the fixing ring 5; the fixing ring 5 drives the positioning block 10 to rotate. When the positioning block 10 rotates to a position corresponding to the positioning groove 9, the positioning block 10 can be removed from the outer side of the connecting column 4. Subsequently, the protective outer cylinder 1 and the filter screen cylinder 2 can be taken out from the outer side of the inner cylinder 6 in sequence, and the disassembly can be completed. This step can effectively limit the fixing ring 5 through the structural design of the cooperation between the positioning block 10 and the positioning groove 9 and the anti-disengagement groove 11, avoiding the fixing ring 5 from sliding from the outer side of the connecting column 4, thereby improving the convenience of installing the protective outer cylinder 1 and the filter screen cylinder 2.

[0028] Further, as Figure 3 shown, a connecting plate 7 is provided at a position corresponding to the fixing ring 5 on the inner side of the top end of the protective outer cylinder 1; the connecting plate 7 is slidably connected to the connecting column 4; a plurality of first springs 8 are uniformly fixed at the lower end of the connecting plate 7; one end of the first spring 8 away from the connecting plate 7 is fixed to the protective outer cylinder 1. During operation, when the fixing ring 5 is installed on the connecting column 4 through the anti-disengagement groove 11, the first spring 8 can continuously apply an upward force to the fixing ring 5 through the first spring 8, thereby completing the limitation of the fixing ring 5. This step can effectively limit the fixing ring 5 through the structural design of the first spring 8 and the connecting plate 7, avoiding the fixing ring 5 from sliding up and down and improving the stability of the fixing ring 5.

[0029] As Figure 5As shown, the limit component includes a plug-in block 19; the plug-in block 19 is arranged at the inner side of the limit block 17; the plug-in block 19 is slidably connected to the limit block 17; one end of the plug-in block 19 extends to the outside of the limit block 17; an annular limit groove 18 is formed at the position corresponding to the limit block 17 inside the connecting column 4; the limit block 17 is slidably connected to the connecting column 4 through the annular limit groove 18; a transmission component is arranged at the position corresponding to the plug-in block 19 inside the limit block 17. When cleaning operation is required during work, first, the transmission component drives the plug-in block 19 to move towards the direction close to the air duct 12. When the plug-in block 19 moves away from the limit block 17, the plug-in block 19 cancels the limit on the air duct 12, so that the air duct 12 can be moved up and down. This step can effectively drive the plug-in block 19 to move through the transmission component, thereby controlling the limit on the limit block 17 through the plug-in block 19, enabling the air duct 12 to be fixed and moved, and effectively avoiding the up and down sliding of the air duct 12 during the use of the device, resulting in damage to the air duct 12 of the device or deterioration of the filtering effect, effectively improving the stability and practicability of the device.

[0030] As Figure 5 shown, the transmission component includes a lifting plate 21; the lifting plate 21 is arranged above the limit block 17; a connecting rod 22 is fixed at the lower end of the limit block 17; the connecting rod 22 extends to the inside of the limit block 17; a moving frame 24 is fixed at the lower end of the connecting rod 22; the moving frame 24 is slidably connected to the limit block 17; a second rack 25 is fixed on one side inside the moving frame 24; a transmission shaft 26 is longitudinally rotatably connected inside the limit block 17; two ends of the transmission shaft 26 are respectively fixed with a second gear 28 and a first gear 27; the second gear 28 is meshed with the second rack 25; a first rack 20 is fixed at the lower end of the plug-in block 19; the first rack 20 is meshed with the transmission shaft 26. During work, when the plug-in block 19 needs to move, first, the lifting plate 21 is pulled; the lifting plate 21 drives the moving frame 24 to move through the connecting rod 22. When the moving frame 24 moves, the transmission shaft 26 is driven to rotate through the second rack 25 and the second gear 28 meshed therewith. When the transmission shaft 26 rotates, the first gear 27 is driven to rotate, so that the first gear 27 drives the plug-in block 19 to move through the first rack 20 meshed therewith. This step can effectively drive the plug-in block 19 to move through the cooperative structural design of the second rack 25, the second gear 28, the first gear 27 and the first rack 20.

[0031] As Figure 5As shown, a second spring 23 is sleeved on the outer side of one end of the connecting rod 22 close to the lifting plate 21; one end of the second spring 23 is fixedly connected to the lifting plate 21; the other end of the second spring 23 is fixedly connected to the limiting block 17. During operation, an upward force on the lifting plate 21 can be continuously applied through the second spring 23, thereby preventing the lifting plate 21 from moving downward. This step can effectively limit the lifting plate 21 through the elastic action of the second spring 23, prevent the lifting plate 21 from moving up and down, and improve the stability of the moving frame 24.

[0032] As Figure 4 shown, a guide frame 14 is arranged inside the inner cylinder 6; the top end of the guide frame 14 is rotatably connected to the inner cylinder 6; the guide frame 14 is slidably connected to the guide block 15; a connecting seat 16 is rotatably connected to the lower end of the guide frame 14; the connecting seat 16 is fixedly connected to the air guide pipe 12. During operation, when the guide block 15 moves up and down, the guide block 15 can be limited through the guide frame 14, so that the guide frame 14 can only slide up and down. This step can effectively complete the vertical limit of the guide block 15 through the guide frame 14, so that the guide block 15 can only move up and down, and at the same time, it does not affect the rotation of the guide block 15, thereby improving the cleaning efficiency.

[0033] Working principle: When filtering, the medium to be filtered flows into the interior of the inner cylinder 6 through the filter screen cylinder 2 and the inner cylinder 6. The filter screen cylinder 2 can filter out the impurities in the medium, and then it is discharged outward through the water outlet 3. When cleaning is required, the air guide pipe 12 is connected to an external air pump, and then the limit on the air guide pipe 12 is cancelled through the limit component area, so that the air guide pipe 12 can move up and down. Subsequently, the high-pressure gas ejected through the air jet 13 cleans the dust and impurities attached to the outer side of the filter screen cylinder 2. When disassembly is required, the protective outer cylinder 1 and the filter screen cylinder 2 can be sequentially removed from the outer side of the inner cylinder 6 through the fixing component to complete the disassembly work; when the protective outer cylinder 1 and the filter screen cylinder 2 need to be disassembled, first press down the fixing ring 5 and then rotate the fixing ring 5; so that the fixing ring 5 drives the positioning block 10 to rotate. When the positioning block 10 rotates to a position corresponding to the positioning groove 9, the positioning block 10 can be removed from the outer side of the connecting column 4, and then the protective outer cylinder 1 and the filter screen cylinder 2 can be sequentially removed from the outer side of the inner cylinder 6 to complete the disassembly; when the fixing ring 5 is installed with the connecting column 4 through the anti-detachment groove 11, the first spring 8 can continuously apply an upward force to the fixing ring 5 through the first spring 8, thereby completing the limitation of the fixing ring 5; when cleaning operation is required, first, the transmission component drives the plug-in block 19 to move in the direction close to the air guide pipe 12. When the plug-in block 19 moves out of engagement with the limit block 17, the plug-in block 19 cancels the limit on the air guide pipe 12, so that the air guide pipe 12 can be moved up and down; when the plug-in block 19 needs to move, first pull the lifting plate 21; so that the lifting plate 21 drives the moving frame 24 to move through the connecting rod 22. When the moving frame 24 moves, the second gear rack 25 and the second gear 28 engaged therewith drive the transmission shaft 26 to rotate. When the transmission shaft 26 rotates, it drives the first gear 27 to rotate, so that the first gear 27 drives the plug-in block 19 to move through the first gear rack 20 engaged therewith; the second spring 23 can continuously apply an upward force to the lifting plate 21, thereby preventing the lifting plate 21 from moving downward; when the guide block 15 moves up and down, the guide frame 14 can complete the limitation of the guide block 15, so that the guide frame 14 can only slide up and down.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
