[0025] Next, with reference to the drawings and specific embodiments, the present invention will be further described:

[0027] The filtering mechanism includes a first filter 5 disposed at the intake end of the exhaust pipe 4 and a second filter 6 disposed at the exhaust end of the exhaust pipe 4. The first filter 5 is used to filter dust in the waste gas, and a first exhaust fan is provided on the exhaust side of the second filter 6. The second filter 6 is used to remove odors in the waste gas.

[0028] A reverse flushing assembly 7 is further disposed in the exhaust pipe 4. The reverse flushing assembly 7 is used to remove dust adhering to the first filter 5.

[0029] In this embodiment, through the setting of the smoke collecting box 3, the generated waste gas is prevented from overflowing outside the processing station, realizing the centralized collection of the waste gas. By arranging a filtering mechanism composed of a first filter 5 and a second filter 6 in the exhaust pipe 4, the waste gas is dust-removed and deodorized before being discharged, so as to meet the environmental protection emission requirements, avoid air pollution at the processing site, and ensure the health of workers.

[0030] In addition, in this embodiment, in order to ensure the continuous and effective dust removal and filtration, a reverse flushing assembly 7 is arranged in the exhaust pipe 4, and the reverse flushing assembly 7 is used to remove the dust adhering to the first filter 5.

[0031] In this embodiment, the roller conveyor mechanism 1 is used to provide power during the transfer process of deburring the aluminum alloy template. The roller conveyor mechanism 1 is an existing technology in the field, and its working principle and structure will not be elaborated here.

[0032] Further, as Figure 1 、 2 shown, sparks will be generated during deburring. In order to block the sparks during the exhaust process and prevent the sparks from entering the exhaust pipe 4 and igniting the dust in the pipe, improving safety; a metal mesh filter 8 is provided on the side of the first filter 5 close to the processing station.

[0033] Further, as Figure 1 、 2 shown, in order to facilitate the replacement of the second filter 6; the second filter 6 is fixedly connected to the intake side of the first exhaust fan, and the first exhaust fan is detachably connected to the exhaust pipe 4. When replacing the second filter 6, only need to disassemble the first exhaust fan from the exhaust pipe; the second filter 6 and the first exhaust fan are connected by means of screwing, clamping, etc.

[0034] Further, as Figure 1 、 2As shown in the figure, in order to stably connect the first exhaust fan to the exhaust pipe 4 and facilitate disassembly from the exhaust pipe 4, a limiting convex ring 41 is provided at the connection between the exhaust pipe 4 and the first exhaust fan. A connecting member 9 is provided at one end of the first exhaust fan away from the second filter 6, and the first exhaust fan is connected to the exhaust pipe 4 through the connecting member 9. Specifically, the connecting member 9 is a right-angled connecting plate, one end of the right-angled connecting plate is connected to the first exhaust fan, and the other end is connected to the exhaust pipe 4 by screws.

[0035] Further, as Figure 1 , 2 shown, the reverse flushing assembly 7 includes a compressed air source 71, a dust collection box 72, an air inlet interface 73 and an air outlet interface 74 provided on the exhaust pipe 4. The air inlet interface 73 is located between the first filter 5 and the second filter 6, and the air outlet interface 74 is located on the air inlet side of the first filter 5. The compressed air source 71 is connected to the air inlet interface 73 through a first valve 75, the air outlet interface 74 is connected to the dust collection box 72, and a second exhaust fan 76 is provided on the dust collection box 72.

[0036] In this embodiment, when the first filter 5 fails in filtering performance due to excessive dust adhesion inside, the first exhaust fan stops working, the second exhaust fan 76 starts, the first valve 75 is opened, and the gas from the compressed air source 71 enters the exhaust pipe 4 and flows from the air outlet side to the air inlet side of the first filter 5. Then, the dust detached from the first filter 5 enters the dust collection box 72 through the air outlet interface 74 under the action of the second exhaust fan 76, so as to effectively remove the dust adhered to the first filter 5 and reliably and effectively collect the detached dust, effectively preventing the dust from entering the processing station again.

[0037] Further, as Figure 1 , 2 shown, in order to improve the dust removal effect on the first filter 5 and reduce the pressure relief caused by the high-pressure gas entering the exhaust pipe 4 and flowing out from both ends, the reverse flushing assembly 7 further includes a first air valve 77 and a second air valve 78 provided in the exhaust pipe 4. The first air valve 77 is located between the first filter 5 and the second filter 6, and the second air valve 78 is located on the side of the air outlet interface 74 away from the first filter 5. When performing reverse dust removal on the first filter 5, the first air valve 77 and the second air valve 78 are closed.

[0038] Further, as Figure 1 , 2 shown, in order to improve the dust removal efficiency and effect on the first filter 5, a vibrator 10 is provided at a position on the outer side of the exhaust pipe 4 corresponding to the first filter 5. The vibration generated by the vibrator 10 is transmitted into the first filter 5, and under the combined action of reverse flushing dust removal, rapid and effective dust removal is achieved.

[0039] Further, the second filter 6 is an activated carbon filter.

[0040] Further, as Figure 1 , 2 shown, in order to accurately monitor the filtering effectiveness of the first filter 5; a wind speed sensor 11 is provided in the exhaust pipe 4 between the second air valve 78 and the first filter 5. During operation, when the rotational speed of the first exhaust fan remains unchanged and the wind speed detected by the wind speed sensor 11 is lower than the set value, it indicates that the filtering effectiveness of the first filter 5 is poor and needs to be replaced.

[0041] For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all such changes and deformations should fall within the protection scope of the claims of the utility model patent.
