[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Combination Figures 1 to 6An automatic soot blowing air filtration device for flues includes a Y-shaped pipe 1, a pressing mechanism 2 is provided on the outside of the Y-shaped pipe 1, and a limit mechanism 3 is provided on one side of the pressing mechanism 2;

[0029] The clamping mechanism 2 includes a support box 21, which is located inside the limiting mechanism 3. A threaded rod 22 is threadedly connected to the inner wall of the support box 21. A rectangular plate 23 is rotatably connected to one end of the threaded rod 22. A support column 24 is fixedly connected to the side of the rectangular plate 23 away from the threaded rod 22. A reinforcing plate 25 is fixedly connected to the side of the support column 24 away from the rectangular plate 23. A torsion block 202 is fixedly connected to the outer wall of the threaded rod 22. A sealing cover 26 is movably connected to the outer wall of the Y-shaped pipe 1. A sealing ring 27, a sealing plug 28, and a sealing ring 29 are fixedly connected to the inner side of the sealing cover. A filter screen cylinder 201 is movably connected inside the Y-shaped pipe 1.

[0030] Furthermore, the sealing plug 28 is movably connected to the inner wall of the filter cylinder 201, and the sealing ring 27 is set at the bottom of the filter cylinder 201 to provide a stable seal for the filter cylinder 201.

[0031] Furthermore, a sealing groove is provided at the bottom of the Y-shaped pipe 1, and the sealing ring 29 is movably connected to the inner wall of the sealing groove for further sealing.

[0032] Furthermore, the rectangular plate 23 is slidably connected to the inner wall of the support box 21, and the top of the reinforcing plate 25 is in contact with the bottom of the sealing cover 26, so that the reinforcing plate 25 can stably press and limit the sealing cover 26.

[0033] Furthermore, a movable opening is provided on one side of the support box 21, through which the support column 24 moves, allowing the support column 24 to move through the movable opening.

[0034] Example 2

[0035] See Figures 1 to 6 Furthermore, based on Embodiment 1, the limiting mechanism 3 further includes a connecting plate 31, which is fixedly connected to the outer wall of the Y-shaped pipe 1. A support shaft 34 is rotatably connected inside the connecting plate 31. A twist block 33 is threadedly connected to the outer wall of the support shaft 34. A pressing plate 32 is fixedly connected to the bottom of the twist block 33. A support sleeve 35 is fixedly connected to the outer wall of the support shaft 34, ensuring that the reinforcing plate 25 can be stably reinforced and limited.

[0036] Furthermore, the bottom of the clamping plate 32 contacts the top of the connecting plate 31, the clamping plate 32 passes through the support shaft 34, and the support sleeve 35 is fixedly connected to the outside of the support box 21.

[0037] In actual operation, when this device is used, it can first be connected to the flue gas duct through the Y-shaped pipe 1. During daily use, due to the impurity of the compressed air, iron filings often cause blockage or jamming of the electronic valve. At this time, the Y-shaped pipe 1 can filter the generated iron filings, reducing the pipeline from being in a constant exhaust state and achieving good performance.

[0038] During prolonged use, when it is necessary to clean the iron filings collected inside the filter cylinder 201, the second torsion block 33 can be rotated first. Since the second torsion block 33 and the support shaft 34 are threadedly connected, and the second torsion block 33 can drive the threaded rod 22 to move, the threaded rod 22 will no longer press against the connecting plate 31. At this time, the support shaft 34 is in a rotatable state. Then the support box 21 can be rotated to make a circular motion along the axis of the support shaft 34 through the support sleeve 35, which facilitates the further disassembly of the filter cylinder 201.

[0039] When the support sleeve 35 can drive the support shaft 34 to rotate, the rotating torsion block 202 can drive the threaded rod 22 to rotate. Since the threaded rod 22 and the support box 21 are threadedly connected, and the rectangular plate 23 can slide and limit its movement on the inner wall of the support box 21, the threaded rod 22 will drive the rectangular plate 23 to move. The rectangular plate 23 can drive the reinforcing plate 25 to move through the support column 24, allowing the reinforcing plate 25 to move away from the sealing cover 26. The reinforcing plate 25 no longer needs to press and limit the sealing cover 26. Then, the support sleeve 35 can rotate. The support box 21 drives the support shaft 34 to rotate through the support sleeve 35, so that the reinforcing plate 25 is not located at the bottom of the sealing cover 26. Then, the sealing plug 28 can be pulled out from the inside of the filter screen cylinder 201 through the sealing cover 26, and then the filter screen cylinder 201 can be pulled out from the inside of the Y-shaped pipe 1, thereby realizing the disassembly of the filter screen cylinder 201. This facilitates the disassembly and cleaning of the filter screen cylinder 201. No large number of bolts are needed for disassembly and assembly. During long-term use, when it is necessary to disassemble and assemble the filter screen cylinder 201, good operational efficiency can be achieved.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
