[0022] Refer toFigures 1-6 , an exhaust gas treatment device with an anti-blocking function, comprising, The main body structure 100 includes a treatment device 101. One side of the treatment device 101 is provided with an intake pipe 102 and an outlet pipe. One side of the bottom of the intake pipe 102 is connected to a first manifold 103 through a flange. A first valve 104 is fixedly connected to the connection between the first manifold 103 and the intake pipe 102. The other side of the bottom of the intake pipe 102 is connected to a second manifold 105 through a flange. A second valve 106 is fixedly connected to the connection between the second manifold 105 and the intake pipe 102. One side of the first manifold 103 and the second manifold 105 is connected to the treatment device 101 through a flange. A filter screen 107 is fixedly connected to the inner cavity of the treatment device 101; and, The maintenance component 200 includes a dust cleaning member 201 for automatically cleaning the filter screen 107. A collection member 203 corresponding to the position of the filter screen 107 is provided on one side of the treatment device 101. There is a linkage member 202 between the dust cleaning member 201 and the collection member 203.

[0023] Specifically, in the main body structure 100, the treatment device 101 is the core. The intake pipe 102 is used to introduce exhaust gas. The first manifold 103, the second manifold 105 and the corresponding first valve 104 and second valve 106 can realize the switching of intake air. At this time, the manifold to be cleaned is disassembled, and then the connection between the manifold and the treatment device 101 is blocked by a plug to avoid shutdown when cleaning the inner wall of the pipeline. The filter screen 107 is used to filter the soot in the exhaust gas. The maintenance component 200 is used to clean and maintain the filter screen 107 to prevent blockage and ensure the stable operation of the device.

[0024] In the present invention, the dust cleaning member 201 includes a first cleaning plate 2013 and a second cleaning plate 2014. A first rotating shaft 2012 rotatably connected to the upper end of the treatment device 101 is provided at the upper end of the first cleaning plate 2013. A second cleaning plate 2014 rotatably connected to the upper end of the treatment device 101 is provided at the upper end of the second cleaning plate 2014. The cleaning ranges of the first cleaning plate 2013 and the second cleaning plate 2014 partially overlap, and the first cleaning plate 2013 and the second cleaning plate 2014 do not interfere with each other when rotating. The first rotating shaft 2012 and the second rotating shaft 2015 rotate, thereby driving the first cleaning plate 2013 and the second cleaning plate 2014 to rotate. Through this mechanical cleaning method, the soot on the filter screen 107 can be automatically cleaned, and the soot on the filter screen 107 is scraped to the end of the filter screen 107 to accumulate, facilitating subsequent scraping operations.

[0025] In the present invention, the surfaces of the first rotating shaft 2012 and the second rotating shaft 2015 are rotatably connected to the first limit plate 2016 through bearings. One side of the first limit plate 2016 is fixedly connected to the inner cavity of the processing equipment 101. The first limit plate 2016 plays a supporting and limiting role to ensure the stability of the first rotating shaft 2012 and the second rotating shaft 2015 during the rotation process, avoid shaking that affects the cleaning effect, and ensure the normal operation of the cleaning part 201. The linkage part 202 includes a third rotating shaft 2021 arranged on one side of the processing equipment 101. The surfaces of the first rotating shaft 2012, the second rotating shaft 2015 and the third rotating shaft 2021 are fixedly connected to the sprockets 2022, and the sprockets 2022 are connected for transmission through chains 2023.

[0026] Specifically, the third rotating shaft 2021 is connected to the first rotating shaft 2012 and the second rotating shaft 2015 through the sprocket 2022 and the chain 2023. This linkage method enables the motor 2011 to drive the first rotating shaft 2012 to rotate, and can synchronously drive the second rotating shaft 2015 and the third rotating shaft 2021 to rotate, thereby realizing the coordinated work between the various components and improving the cleaning efficiency.

[0027] In the present invention, the surface of the third rotating shaft 2021 is rotatably connected to the second limit plate 2024 through a bearing. One side of the second limit plate 2024 is fixedly connected to the processing equipment 101. The second limit plate 2024 provides support and limitation for the third rotating shaft 2021, ensuring its stability during rotation, making the transmission of the linkage 202 more reliable, and ensuring the normal operation of the entire cleaning system.

[0028] In the present invention, a waste discharge port 2035 corresponding to the position of the filter net 107 is provided on the side wall of the processing device 101. The collection member 203 includes a collection box 2042 detachably installed on one side of the waste discharge port 2035. An upper scraper 2031 and a lower scraper 2032 are provided at the waste discharge port 2035. The upper scraper 2031 is stacked above the lower scraper 2032. A first spring hinge 2033 is connected between the outer wall surfaces of the upper scraper 2031 and the lower scraper 2032. A driving device for driving the upper scraper 2031 to extend into or withdraw from the waste discharge port 2035 is provided outside the processing device 101. A flip-type blocking mechanism for blocking the lower scraper 2032 is provided inside the processing device 101. The flip-type blocking mechanism includes a blocking plate 2040. One end of the blocking plate 2040 abuts against the inner wall of the processing device 101. A second spring hinge 2041 that only allows the blocking plate 2040 to rotate and open towards the waste discharge port 2035 is provided between the blocking plate 2040 and the processing device 101. The driving device includes a rotating shaft 2036 that rotates synchronously with the third rotating shaft 2021. A gear 2037 is fixedly connected to the bottom of the rotating shaft 2036. A toothed track 2038 is meshed with the circumference of the gear 2037. One end of the toothed track 2038 is fixedly connected to the upper scraper 2031 through a connecting optical rod 2034. A sliding seat 2039 slidably connected to the toothed track 2038 is provided on the outer side wall of the processing device 101.

[0029] Specifically, the rotating shaft 2036 at the bottom of the third rotating shaft 2021 drives the gear 2037 to rotate. The gear 2037 meshes with the toothed track 2038, causing the connecting optical rod 2034 to drive the upper scraper 2031 and the lower scraper 2032 to perform reciprocating motion. When the lower scraper 2032 moves to contact the blocking plate 2040, since the end face of the blocking plate 2040 contacts the inner wall of the processing device 101, the lower scraper 2032 is forced to flip outwards around the first spring hinge 2033 until it passes over the blocking plate 2040. Then the first spring hinge 2033 rebounds and resets to drive the lower scraper 2032 to flip inwards and reset. At this time, the lower scraper 2032 passes over the position of the soot accumulated on the filter net 107, and the bottom end of the lower scraper 2032 contacts the filter net 107. Then when the lower scraper 2032 moves outwards, it scrapes the soot accumulated on the filter net 107. When the lower scraper 2032 moves to contact the blocking plate 2040, the blocking plate 2040 flips outwards around the second spring hinge 2041 to avoid the lower scraper 2032. Since the top end of the lower scraper 2032 is in contact with the bottom end of the upper scraper 2031, the lower scraper 2032 will not flip. At this time, the lower scraper 2032 continues to move outwards and scrapes the soot accumulated on the filter net 107 to the top opening of the collection box 2042, and the soot is collected through the collection box 2042.

[0030] The working principle of the present invention: S1: Exhaust gas enters the treatment device 101 through the intake pipe 102 and the first manifold 103. When the inner wall of the first manifold 103 needs to be cleaned, the first valve 104 is closed and the second valve 106 is opened. The exhaust gas enters the treatment device 101 through the second manifold 105. At this time, the first manifold 103 can be disassembled for cleaning, and then the connection between the first manifold 103 and the treatment device 101 is sealed with a plug. When cleaning the second manifold 105, the reverse operation is performed; S2: The exhaust gas entering the processing equipment 101 is filtered through the filter 107, and the smoke and dust are intercepted on the filter 107. When the smoke and dust on the filter 107 need to be cleaned, the exhaust gas input is stopped, and then the motor 2011 is started to drive the first rotating shaft 2012 to rotate. The sprocket 2022 on the first rotating shaft 2012 drives the second rotating shaft 2015 and the third rotating shaft 2021 to rotate synchronously through the chain 2023. The first rotating shaft 2012 drives the first cleaning plate 2013, and the second rotating shaft 2015 drives the second cleaning plate 2014 to clean the filter 107, so that the smoke and dust on the filter 107 are scraped to the end of the filter 107 and accumulated, which is convenient for subsequent scraping operations; S3: At the same time, the rotating shaft 2036 at the bottom of the third rotating shaft 2021 drives the gear 2037 to rotate, and the gear 2037 engages with the toothed track 2038, so that the connecting rod 2034 drives the upper scraper 2031 and the lower scraper 2032 to reciprocate. When the lower scraper 2032 moves to contact the blocking plate 2040, since the end surface of the blocking plate 2040 contacts the inner wall of the processing equipment 101, the lower scraper 2032 is forced to flip outward around the spring hinge 2033 until it passes over the blocking plate 2040, and then the spring hinge 2033 rebounds and resets, driving the lower scraper 2032 to flip inward and reset. At this time, the lower scraper 2032 passes the position where the smoke and dust accumulates on the filter 107, and the bottom end of the lower scraper 2032 contacts the filter 107; S4: Then when the lower scraper 2032 moves outward, the smoke and dust accumulated on the filter 107 are scraped out. When the lower scraper 2032 moves to contact the blocking plate 2040, the blocking plate 2040 flips over around the spring hinge 2041 and avoids the lower scraper 2032. Since the top of the lower scraper 2032 is in contact with the bottom of the upper scraper 2031, the lower scraper 2032 will not flip over. At this time, the lower scraper 2032 continues to move outward and scrapes the smoke and dust accumulated on the filter 107 to the top opening of the collection box 2042, and is collected by the collection box 2042.

[0031] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
