[0023] See also Figure 1 - Figure 5 As shown, an exhaust gas treatment device for aircraft tire processing includes a filter box 1, an air inlet 20 and a filter screen 39; the filter screen 39 is inserted into a fixed frame 38, the top of the fixed frame 38 contacts the cover plate 22, and the cover plate 22 is provided with a snap-fit mechanism, which includes a fixed block 23, the fixed block 23 is trapezoidal in design, and the fixed block 23 is inserted into the interior of a fixed groove 46, the fixed groove 46 is rectangular in design, and a first spring 24 is welded to one side of the fixed block 23, and the side of the first spring 24 away from the fixed block 23 is welded to the inner wall of the first movable groove 25. The first movable groove 25 is provided on the front and rear sides of the cover plate 22. The first movable groove 25 is designed as a long rectangle. Insert blocks 26 are inserted on the left and right sides of the fixed block 23. The insert blocks 26 are slidably connected to the inside of the second movable groove 27. A second spring 28 and a connecting rod 29 are welded and fixed to the insert block 26. The connecting rod 29 is close to the rotating block 30. The rotating block 30 is rotatably connected to the filter box 1. A protrusion 31 is welded and fixed to the top of the rotating block 30. The second movable groove 27 and the fixed groove 46 are provided inside the filter box 1. Three sets of partitions 21 are welded and fixed inside the filter box 1.

[0024] During operation, a tire vulcanization waste gas purification treatment device in the above technology needs to disassemble the box cover before taking out the filter each time the filter is replaced, and then reinstall the box cover at the end. The operation process is relatively cumbersome. The structural design of the locking mechanism realizes the function of facilitating the removal of the filter 39 placed inside the filter box 1 for replacement. When the filter 39 inside the filter box 1 is to be replaced, the rotating blocks 30 on the front and rear sides of the filter box 1 are first rotated. During the rotation process, the two sides of the rotating block 30 will contact the connecting rod 29 and push the connecting rod 29 to move to both sides. The bottom end of the connecting rod 29 is connected to the plug block 26, so that the plug block 26 will be 6 moves inside the second movable groove 27, and the second spring 28 is compressed. When the insert block 26 is no longer inserted in the fixed block 23, the cover plate 22 can be pulled upward. At this time, the filter screen 39 inserted inside the fixed frame 38 can be replaced, which is more convenient. The outer side of the fixed frame 38 is in contact with the partition 21, and mesh holes are provided on the front and back sides of the fixed frame 38 so that the exhaust gas can smoothly enter the filter screen 39 for filtration. The filter screen 39 is placed vertically, which increases the contact time between the exhaust gas and the filter screen 39, thereby ensuring the filtering effect of the filter screen 39 on the exhaust gas. The three groups of partitions 21 divide the filter box 1 into four compartments to ensure that when one group of filter screens 39 is replaced, the remaining filter screens 39 can work normally.

[0025] Furthermore, a clamping block 32 is welded and fixed on both the left and right sides of the fixed block 23. The clamping block 32 is slidably connected to the inside of the clamping slot 33. The clamping slot 33 is provided on the inner wall of the first movable slot 25.

[0026] During operation, a clamping block 32 is fixed on the fixed block 23. During the process of removing the cover plate 22, the fixed block 23 will move toward the inside of the first movable groove 25. At this time, the clamping block 32 will slide in the clamping groove 33, thereby limiting the movement range of the fixed block 23 in the first movable groove 25 and ensuring that the first spring 24 will not be over-stretched.

[0027] Furthermore, a transfer block 35 is welded and fixed to the bottom end of the rotating block 30, and the transfer block 35 is T-shaped;

[0028] During operation, the bottom end of the rotating block 30 is rotatably connected to the filter box 1 through a fixed adapter block 35. The adapter block 35 is T-shaped to ensure that the rotating block 30 will not be separated from the filter box 1 while rotating.

[0029] Furthermore, the protrusion 31 is provided with anti-slip grooves, and the bottom end of the rotating block 30 is provided with a groove 34. A gasket 36 is glued and fixed inside the groove 34. The gasket 36 is made of rubber and contacts the top of the filter box 1.

[0030] During operation, a protrusion 31 is fixed on the rotating block 30 so that the rotating block 30 can be rotated by the protrusion 31, and anti-slip grooves are provided on the protrusion 31 to increase friction. The gasket 36 is used to increase the friction of the rotating block 30 during the rotation process to ensure that the rotating block 30 will not rotate easily.

[0031] Furthermore, a fixing plate 40 is welded and fixed to both the front and rear sides of the fixing frame 38. The bottom end of the fixing plate 40 abuts against the baffle 41. The baffle 41 is welded and fixed to the support plate 43. The bottom end of the support plate 43 is welded and fixed to a third spring 44. The support plate 43 contacts the inner wall of the filter box 1. The bottom end of the third spring 44 is welded and fixed to the inner wall of the filter box 1.

[0032] During operation, through the structural design of the fixing plate 40, the baffle 41, the support plate 43 and the third spring 44, when the fixing frame 38 is fixed in the interior of the filter box 1, the fixing plate 40 will abut against the protrusion 31 and squeeze the third spring 44 at the bottom end of the support plate 43, and in the process of removing the filter 39 inside the fixing frame 38, the third spring 44 will push the baffle 41 to move upward, and the baffle 41 will block the air inlet 20, thereby ensuring that when one group of filters 39 is replaced, the exhaust gas will not enter the interior of the filter box 1 from the air inlet 20 of the group.

[0033] Furthermore, the left and right sides of the support plate 43 are both welded with fixed limit blocks 42, and the limit blocks 42 are slidably connected to the inside of the limit groove 45, which is opened on the inner wall of the partition 21;

[0034] During operation, the limiting block 42 slides in the limiting groove 45 to ensure that the supporting plate 43 can stably move up and down inside the filter box 1 .

[0035] Working principle: In the prior art, a device for purifying and treating waste gas from tire vulcanization needs to disassemble the box cover before taking out the filter each time the filter is replaced, and then reinstall the box cover at the end. The operation process is relatively cumbersome. In this case, a waste gas treatment device for aircraft tire processing realizes the function of facilitating the removal and replacement of the filter 39 placed inside the filter box 1 through the structural design of the locking mechanism. When the filter 39 inside the filter box 1 is to be replaced, the rotating blocks 30 on the front and rear sides of the filter box 1 are first rotated. During the rotation process, the two sides of the rotating block 30 will contact the connecting rod 29 and push the connecting rod 29 to move to both sides. The bottom end of the connecting rod 29 is connected to the plug block 26. Together, the insert block 26 will move inside the second movable groove 27, and the second spring 28 will be compressed. When the insert block 26 is no longer inserted in the fixed block 23, the cover plate 22 can be pulled upwards. At this time, the filter screen 39 inserted inside the fixed frame 38 can be replaced, which is more convenient. The outer side of the fixed frame 38 is in contact with the partition 21, and mesh holes are provided on the front and back sides of the fixed frame 38 so that the exhaust gas can smoothly enter the filter screen 39 for filtration. The filter screen 39 is placed vertically, which increases the contact time between the exhaust gas and the filter screen 39, thereby ensuring the filtering effect of the filter screen 39 on the exhaust gas. The three groups of partitions 21 divide the filter box 1 into four compartments to ensure that when one group of filters 39 is replaced, the remaining filters 39 can work normally.
