Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to a self-cleaning air filtration component. Background Art

[0002] As an important place for extracting mineral resources, the mineral processing plant will produce a large amount of pollutants such as dust, harmful gases and microorganisms during its production process. These pollutants not only seriously pollute the natural environment of the production site and the factory area, but also pose a direct threat to the health of the operators. The air filter component is an air filter device, which is a device specially used to remove pollutants from the air. It intercepts or adsorbs pollutants such as particulate matter, harmful gases, microorganisms in the air through physical or chemical methods, thereby outputting clean air. The use of air filter components can effectively remove dust and harmful gases in the air, reduce the risk of workers becoming ill due to inhaling pollutants, and protect the health of workers.

The mounting mechanism is located at the connection between the filter body and the filter element support frame. The mounting mechanism includes a buckle, and one side of the buckle is located outside the filter body. A placement groove is provided on one side surface of the filter body, and first sliding grooves are provided on both side surfaces of the placement groove. A third clip groove is provided on the front end surface of the filter body.

[0004] Although the above solution facilitates timely maintenance and improves maintenance efficiency, the air filter lacks the self-cleaning function, which requires frequent and regular manual dust removal, increases labor intensity, and thus affects actual operation. Therefore, it does not meet existing needs. In this regard, we have proposed a self-cleaning air filter assembly. Utility Model Content

[0027] It also includes an ash box 15, which is arranged at the lower end of the main body 1, and the ash box 15 is communicated with the filter chamber 8. A spiral conveying rod 16 is rotatably provided inside the ash box 15, and a cylindrical connecting block 19 is provided on one side of the interior of the ash box 15, and the cylindrical connecting block 19 is threadedly connected to the ash box 15, one end of the cylindrical connecting block 19 extends to the outside of the ash box 15, and a pressure plate 18 is provided at one end of the cylindrical connecting block 19 located outside the ash box 15, and the pressure plate 18 is in contact with the ash box 15.

[0028] During use, air is introduced through the air inlet pipe 2, enters the bottom of the filter chamber 8 through the conversion chamber 9, is filtered by the dust filter bag 7, and is lifted to the top through the Venturi tube 5 and discharged from the first air outlet pipe 3. During cleaning, dust-free air passes through the air inlet pipe 2, and the electric telescopic rod 10 drives the blocking block 13 to close the first connecting pipe 11, guiding the air to backwash the dust filter bag 7 through the Z-shaped through hole 14 and the second connecting pipe 12, and the dust falls into the ash box 15. The handle 21 is rotated to separate the cylindrical connecting block 19, and the motor 17 is started to drive the spiral conveying rod 16 to rotate, so that the dust is discharged smoothly and blockage is avoided, thereby realizing an efficient and convenient cleaning process.

[0029] See also Figure 2 An electric telescopic rod 10 is provided on the upper side of the conversion chamber 9, and a blocking block 13 is provided at the output end of the electric telescopic rod 10. The blocking block 13 is slidably matched with the conversion chamber 9. The electric telescopic rod 10 can accurately control the up and down movement of the blocking block 13 to achieve rapid and effective closing and opening of the first connecting pipe 11, thereby flexibly adjusting the air flow direction to ensure the smooth progress of the backwash process;

[0030] See also Figure 3A Z-shaped through hole 14 is provided inside the block 13. The Z-shaped through hole 14 can cleverly guide the dust-free air through the block 13 into the second connecting pipe 12, thereby backwashing the dust filter bag 7, effectively cleaning the dust attached to the filter bag, and improving the dust removal efficiency;

[0031] See also Figure 1 and Figure 2 A motor 17 is provided on one side of the ash box 15, and the output end of the motor 17 is connected to the spiral conveying rod 16 through a coupling.

[0032] See also Figure 4 The inner wall of the pressing plate 18 is adhered and fixed with an annular rubber ring 20, which can enhance the sealing between the pressing plate 18 and the ash box 15 to prevent gas leakage;

[0033] See also Figure 1 and Figure 4 A handle 21 is installed on the outside of the pressing plate 18. The handle 21 provides a convenient gripping point for the operator, making the rotation and removal of the pressing plate 18 easier and more labor-saving, thereby improving work efficiency and convenience of operation;

[0034] See also Figure 1 and Figure 2 A first air outlet pipe 3 is provided on the upper side of one side of the main body 1, and a second air outlet pipe 22 is provided below the first air outlet pipe 3. One end of the first air outlet pipe 3 and the second air outlet pipe 22 are both provided with an electromagnetic valve 4, and one end of the first air outlet pipe 3 and the second air outlet pipe 22 are both extended to the interior of the filter cavity 8. The first air outlet pipe 3 and the second air outlet pipe 22 are used in conjunction with the electromagnetic valve 4 to flexibly control the air exhaust path. The filtered air can be discharged through the first air outlet pipe 3 during normal operation, and dust-free air can be discharged through the second air outlet pipe 22 for backwashing during the cleaning process.

[0035] Working principle: When in use, the air in the mineral processing plant can be connected to the air inlet pipe 2 through the external fan, so that the air in the mineral processing plant can enter the conversion chamber 9. At this time, the air will directly enter the lower side of the inside of the filter chamber 8 through the first connecting pipe 11, and the air will be filtered through the dust filter bag 7, and then enter the upper side of the inside of the filter chamber 8 through the venturi tube 5, and be discharged through the first air outlet pipe 3. When the dust filter bag 7 needs to be cleaned, the operator allows dust-free air to pass through the air inlet pipe 2, and starts the electric telescopic rod 10 to move the blocking block 13 downward. The downward movement of the blocking block 13 will seal and block the first connecting pipe 11, preventing dust-free air from entering the lower side of the inside of the filter chamber 8 through the first connecting pipe 11. The dust-free air will enter the second connecting pipe 12 through the Z-shaped through hole 14 The dust-free air will move downward from above to backwash the dust filter bag 7, thereby cleaning the attached dust. The dust will fall into the ash box 15 by gravity. The operator grabs the handle 21 and rotates it to separate the cylindrical connecting block 19 from the ash box 15, and starts the motor 17. The motor 17 will rotate the spiral conveying rod 16 through the coupling, thereby transporting the dust and transporting it to the discharge port without clogging. This makes it possible to easily remove the dust and effectively avoid the accumulation and clogging of dust inside the ash box 15.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
