[0030] Refer to Figures 1 to 6As shown, the embodiment of the present application provides a furnace chimney, including a square chimney 2, wherein a flue gas purification device is arranged inside the square chimney 2, wherein the flue gas purification device includes a bracket, a filter 5, a T-shaped brush 10 and a driving mechanism; the bracket is fixedly mounted on the inner wall of the square chimney 2, the filter 5, the T-shaped brush 10 and the T-shaped brush 10 are all mounted on the bracket, and the filter 5, the T-shaped brush 10 and the T-shaped brush 10 are arranged in the upper, middle and lower positions. Among them, the T-shaped brush 10 is slidably connected to the bracket, and the bristles of the T-shaped brush 10 are in contact with the lower surface of the filter 5; the driving mechanism is transmission-connected to the T-shaped brush 10, and is used to drive the T-shaped brush 10 to translate. When in use, the T-shaped brush 10 is driven to translate by the driving mechanism, and the lower surface of the filter 5 is scrubbed and cleaned during the translation of the T-shaped brush 10, without manual disassembly, simple cleaning, time-saving and labor-saving, and improved cleaning efficiency, and there is no need to stop production.

[0031] Reference Figure 5 and Figure 6 As shown, in some specific embodiments, the T-shaped brush 10 includes a vertical plate 101 and a horizontal plate 102 , the vertical plate 101 is fixed on the upper surface of the horizontal plate 102 to form a T-shaped cross-sectional structure, and the bristles are fully spread on the upper surface of the vertical plate 101 .

[0032] Reference Figure 3 As shown, in some embodiments, the bracket includes two side panels 4, which are fixed on the left and right inner walls of the square chimney 2, and two guide rods 11 are arranged between the two side panels 4. The two ends of the vertical plate 101 are respectively mounted on the two guide rods 11 and slide with them, so that the T-shaped brush 10 can slide on the guide rods 11 to brush the filter 5 back and forth, and the structure is simple.

[0033] Furthermore, the bracket also includes a bottom plate 6 , which is fixedly connected to the two side plates 4 and is used for installing the driving mechanism, and can also support and reinforce the two side plates 4 .

[0034] Reference Figures 3 - 6As shown, in some embodiments, the driving mechanism includes a first rotating rod 7, a strip-shaped plate 8, a short column 9, and a power source; a through hole is provided on the bottom plate 6, and the first rotating rod 7 passes through the through hole and can also be connected to the bottom plate 6 through a bearing; the upper end of the first rotating rod 7 is fixed to one end of the lower surface of the strip-shaped plate 8, and the short column 9 is fixed to the upper surface of the other end of the strip-shaped plate 8; the cross plate 102 has a groove 103, and the groove 103 is arranged on the lower surface of the cross plate 102 along the length direction of the cross plate 102; the short column 9 is located in the groove 103 and is slidably matched with the groove 103; the power source is in transmission connection with the first rotating rod 7 and is used to drive the first rotating rod 7 to rotate. During use, the power source is started, which drives the first rotating rod 7 to rotate. The rotation of the first rotating rod 7 will drive the strip-shaped plate 8 to rotate. The strip-shaped plate 8 drives the T-shaped brush 10 to reciprocate through the sliding fit of the short column 9 and the groove 103 and under the guidance of the guide rod 11, realizing the real-time cleaning of the filter net 5. Moreover, the overall structure is simple and reliable.

[0035] Specifically, the power source is a motor (not shown in the figure) and is connected to the lower end of the first rotating rod 7 through a gear set. Of course, other transmission mechanisms similar to the gear set can also be used here, such as a sprocket chain assembly, a belt pulley assembly, etc.

[0036] Alternatively, the power source includes a second rotating rod 15, a fan blade 16, and a bevel gear set. One end of the second rotating rod 15 is connected to the lower end of the first rotating rod 7 through the bevel gear set (the bevel gear set includes a first bevel gear 12 and a second bevel gear 13 that mesh with each other, and the first bevel gear 12 and the second bevel gear 13 are respectively fixed to the ends of the first rotating rod 7 and the second rotating rod 15), the fan blade 16 is fixed to the other end of the second rotating rod 15, and the second rotating rod 15 is rotatably connected to the bottom plate 6 (a support plate 14 is also provided below the bottom plate 6, and the second rotating rod 15 passes through the support plate 14 and is rotatably connected through a rotating connector such as a bearing). During use, the flue gas flowing through the square chimney 2 causes the fan blade 16 to rotate, which in turn drives the second rotating rod 15 to rotate. The second rotating rod 15 drives the first rotating rod 7 to rotate through the first bevel gear 12 and the second bevel gear 13. The rotation of the first rotating rod 7 will drive the strip-shaped plate 8 to rotate. The strip-shaped plate 8 drives the T-shaped brush 10 to reciprocate through the sliding fit of the short column 9 and the groove 103 and under the guidance of the guide rod 11, realizing the real-time cleaning of the filter net 5. The overall structure is simple and reliable, and moreover, no energy is consumed, making full use of the flue gas flowing through the square chimney 2, achieving the effect of energy conservation and emission reduction.

[0037] Refer to Figure 2 As shown, in some embodiments, a rain cap 3 is provided at the top of the square chimney 2 to prevent the internal flue gas purification device from being damaged by rainwater and play a protective role.

[0038] Refer to Figures 1 to 2As shown in the figure, an embodiment of the present application provides a furnace, which includes a furnace body 1 and a square chimney 2 arranged on the top of the furnace body 1. Referring to the above description of the square chimney 2, this furnace also has the functions and effects of any of the above embodiments, so details will not be repeated here.

[0039] In summary, compared with the prior art, one embodiment of the present application has the following beneficial effects: When in use, the flue gas flowing through the chimney causes the fan blades to rotate, which in turn drives the second rotating rod to rotate. The second rotating rod drives the first rotating rod to rotate through the first bevel gear and the second bevel gear. When the first rotating rod rotates, it will drive the strip plate to rotate. The strip plate drives the T-shaped brush to reciprocate through the sliding fit of the short column and the groove and under the guidance of the guide rod, realizing the real-time cleaning of the filter screen. Therefore, the filter screen does not need to be manually disassembled and cleaned, solving the problem of time-consuming, laborious and low efficiency caused by manual disassembly during the cleaning of the filter screen of the existing furnace chimney.
