DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 6 As shown, the utility model provides an exhaust gas purification device, including a purification box 1, an air inlet 11 is provided at the lower end of the purification box 1, an exhaust port 12 is provided at the upper end of the purification box 1, a filter plate 4 is fixedly connected to the inside of the purification box 1, a cleaning mechanism 3 is provided inside the purification box 1, the cleaning mechanism 3 is used to clean impurities attached to the lower end surface of the filter plate 4, the left and right ends of the purification box 1 are fixedly connected to storage boxes 2, and a partition mechanism 5 is provided between the storage box 2 and the purification box 1, the impurities at the lower end of the filter plate 4 can be stored through the cleaning mechanism 3, and the impurities are collected through the cleaning mechanism 3, and then the collected impurities are transferred to the inside of the storage box 2, so as to solve the problem that the impurities may block the filter plate 4, thereby reducing the exhaust gas treatment effect and affecting the exhaust gas emission.

[0025] In a further embodiment, referring to Figure 2-Figure 5 The cleaning mechanism 3 includes a scraper 31 and a limit block 36. The scraper 31 is slidably connected inside the purification box 1. The upper end of the scraper 31 abuts against the lower end of the filter plate 4. The front and rear ends of the scraper 31 are fixedly connected to the limit blocks 36. The purification box 1 is fixedly connected to the fixed block 13. The end surface of the fixed block 13 away from the side wall of the purification box 1 is provided with a limit groove 131. The limit block 36 is located inside the limit groove 131 and is slidably connected thereto. The left and right sides of the scraper 31 are fixedly connected to push rods 35.

[0026] In this embodiment, the scraper 31 moves inside the purification box 1 so that the scraper 31 can clean the impurities attached to the lower end of the filter plate 4, thereby achieving a cleaning effect.

[0027] In a further embodiment, referring to Figure 5 The lower end of the scraper 31 is rotatably connected to a storage plate 32, and the upper ends of the storage plates 32 located on the left and right sides of the scraper 31 are fixedly connected to first arc springs 34, and one end of the first arc spring 34 away from the storage plate 32 is fixedly connected to the side wall of the scraper 31, and the front and rear ends on the left and right sides of the scraper 31 are fixedly connected to protrusions 33.

[0028] In this embodiment, the storage plate 32 is rotatably arranged at the lower end of the scraper 31, so that the impurities attached to the filter plate 4 are cleaned to the top of the storage plate 32 and collected during the movement of the scraper 31, thereby preventing the cleaned impurities from being attached to the filter plate 4 again through the flue gas. The first arc spring 34 is arranged to stabilize the storage plate 32 to always be perpendicular to the scraper 31, preventing impurities from falling on one side of the storage plate 32, thereby causing one side to be heavier and deflected, causing the impurities collected by the storage plate 32 to fall.

[0029] In a further embodiment, referring to Figure 4-Figure 6 The partition mechanism 5 includes a partition 51 and a second arc spring 52. Through holes 15 are opened on the left and right end surfaces of the purification box 1. The through holes 15 penetrate into the interior of the storage box 2. The partition 51 is rotatably connected inside the through holes 15. The end of the partition 51 close to the storage box 2 is fixedly connected to the second arc spring 52, and the end of the second arc spring 52 away from the partition 51 is fixedly connected to the inner wall of the storage box 2.

[0030] In this embodiment, the storage box 2 and the purification box 1 can be separated by the provided partition 51, so as to avoid the problem of smoke overflowing through the storage box 2 when the storage box 2 is manually opened to clean the internal impurities. When the top rod 35 and the partition 51 abut against each other, the partition 51 will be driven to rotate, thereby achieving the effect of opening the through hole 15.

[0031] In a further embodiment, referring to Figure 3-Figure 5 A first arc groove 14 is formed on the inner wall of the storage box 2, and a protrusion 33 on one side of the storage plate 32 cooperates with the first arc groove 14. A second arc groove 132 is formed on the side of the fixing block 13 away from the inner wall of the purification box 1, and a protrusion 33 on the other side of the storage plate 32 cooperates with the second arc groove 132.

[0032] In this embodiment, when the storage plate 32 moves to the position of the first arc groove 14, the protrusion 33 on one side moves into the first arc groove 14, so that when the storage plate 32 continues to move, the protrusion 33 is restricted by the first arc groove 14, causing the storage plate 32 to deflect. When the storage plate 32 deflects to a certain angle, the impurities on the upper end of the storage plate 32 fall into the storage box 2 due to gravity. When the storage plate 32 rotates, the protrusion 33 on the other side moves to the inside of the second arc groove 132, allowing the storage plate 32 to rotate stably.

[0033] In a further embodiment, referring to Figure 6 A bracket 16 is fixedly connected to the inner wall of the through hole 15 , a reserved opening 511 is opened on the upper end surface of the partition 51 , and the bracket 16 is located inside the reserved opening 511 .

[0034] In this embodiment, since the bracket 16 is located inside the reserved opening 511 , the reserved opening 511 can accommodate the bracket 16 .

[0035] In a further embodiment, referring to Figure 3-Figure 6 The two groups of storage boxes 2 are rotatably connected by a threaded rod 6, the threaded rod 6 passes through the scraper 31 and is threadedly connected thereto, both ends of the threaded rod 6 pass through the outer wall of the storage box 2, and the left end of the storage box 2 located on the left side of the purification box 1 is fixedly connected to a motor 7, and the output shaft end of the motor 7 is fixedly connected to the left end of the threaded rod 6.

[0036] In this embodiment, the threaded rod 6 is driven to rotate by starting the motor 7 , and the rotating threaded rod 6 drives the scraper 31 to move, thereby providing power for the scraper 31 to move.

[0037] The working principle of the utility model is as follows: since the smoke enters through the air inlet 11 and is discharged from the exhaust port 12, the impurities in the smoke will adhere to the lower end surface of the filter plate 4, and then the threaded rod 6 is driven to rotate by the starting motor 7, and the rotating threaded rod 6 drives the scraper 31 to move, and the movement of the scraper 31 can clean the impurities at the lower end of the filter plate 4, so that the impurities that fall are collected by the storage plate 32. When the storage plate 32 moves to a certain position, the top rod 35 will abut against the partition plate 51, so that the scraper 31 continues to move to carry the impurities. The movable partition plate 51 rotates to open the through hole 15, and the protrusion 33 on one side moves to the inside of the first arc groove 14, so that when the storage plate 32 continues to move, the first arc groove 14 restricts the protrusion 33, so that the storage plate 32 deflects. When the storage plate 32 deflects to a certain angle, the impurities on the upper end of the storage plate 32 fall into the storage box 2 by gravity. When the storage plate 32 rotates, the protrusion 33 on the other side moves to the inside of the second arc groove 132, so that the storage plate 32 can rotate stably.

[0038] When the motor 7 rotates in the opposite direction, it drives the scraper 31 to move in the opposite direction. At this time, the second arc spring 52 restores its deformation to drive the partition 51 to rotate, so that the partition 51 moves to the inside of the through hole 15, thereby continuing to separate the storage box 2 and the purification box 1, and the storage plate 32 loses the restriction of the protrusion 33 and the first arc groove 14, and drives the storage plate 32 to rotate when the first arc spring 34 restores its deformation, so that the storage plate 32 can remain vertical to the scraper 31, thereby continuing to collect the fallen impurities, thereby solving the problem that impurities may block the filter plate 4, thereby reducing the exhaust gas treatment effect and affecting exhaust gas emissions.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
