DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-2 In this embodiment, an exhaust gas treatment device that is easy to replace the filter element includes a filter box 1. An air inlet 2 is fixed on the front of the filter box 1. The air inlet 2 is provided to be connected to an external exhaust gas pipe, so that the external exhaust gas can smoothly enter the interior of the filter box 1, thereby effectively improving the stability of the exhaust gas treatment and making the overall more practical. An exhaust port 3 is fixed on the back of the filter box 1. Positioning plates 4 are fixed on the left and right side walls of the inner cavity of the filter box 1. The positioning plates 4 are "concave" plates. The provided positioning plates 4 can effectively position the positioning component 6, so that the positioning component 6 is not easy to shake, effectively improving the stability of the exhaust gas filtration.

[0022] In addition, a limiting plate 5 is fixed on the top of the two positioning plates 4. The limiting plate 5 can effectively limit the sliding block 602 from passing through the limiting plate 5, so that the positioning component 6 as a whole is not easy to be separated from the filter box 1, effectively preventing the loss of the positioning component 6, thereby making the whole more practical.

[0023] The filter box 1 has a plurality of independently controlled air filters 6, each of which is provided with a plurality of independently controlled air filters 6. The filter box 1 has a plurality of independently controlled air filters 6, each of which is provided with a plurality of independently controlled air filters 6. The filter box 1 has a plurality of independently controlled air filters 6, each of which is provided with a plurality of independently controlled air filters 6. The filter box 1 has a plurality of independently controlled air filters 6, each of which is provided with a plurality of independently controlled air filters 6.

[0024] In general, the rotating rod 7 can drive the rotating plate 8 to rotate, so that the rotating plate 8 can be rotated into the fixing groove 11 to fix the positioning assembly 6, so that the whole is easy to install and disassemble.

[0025] See also Figure 3In order to facilitate the replacement of the filter element, the positioning assembly 6 in this embodiment includes a positioning block 601, two sliding blocks 602, a filter element 603 and a fixed plate 604. The interior of the positioning plate 4 is slidably connected to the positioning block 601. The positioning block 601 is a hollow square. A taking groove is provided on the front of the positioning block 601. The left and right sides of the positioning block 601 are fixed to the sliding block 602. The filter element 603 is placed inside the positioning block 601. The positioning block 601 is used to position the filter element 603 and cooperates with the positioning plate 4 to effectively limit the filter element 603 inside the positioning block 601.

[0026] In addition, the top of the positioning block 601 is fixed to the fixed plate 604, and a sealing gasket is fixed to the outer surface of the fixed plate 604. The sealing gasket can effectively improve the sealing when the fixed plate 604 is connected to the filter box 1, so that air leakage is not easy to occur. A through hole is provided on the top of the fixed plate 604, and a fixed bearing is fixed in the hole of the through hole. The inside of the fixed bearing is fixed to the rotating rod 7. The fixed bearing can be used to position the position of the rotating rod 7 and make the rotation of the rotating rod 7 more stable. A fixed hole connected to the through hole is provided on the front of the fixed plate 604, and the rotating plate 8 is located inside the fixed hole. The length of the rotating plate 8 is greater than the width of the fixed plate 604. Because the length of the rotating plate 8 is larger, when the rotating plate 8 rotates, it will rotate to the outside of the fixed plate 604, so that the rotating plate 8 can enter the inside of the fixed groove 11.

[0027] In general, the positioning block 601 is set to position the filter element 603. When the filter element 603 needs to be taken out, the positioning block 601 is pulled out, and the filter element 603 can be taken out and replaced from the front. The overall structure is simple, which effectively improves the efficiency of replacing the filter element 603.

[0028] The working principle of the above embodiment is:

[0029] After connecting the external exhaust pipe to the air inlet 2, the external fan is started to draw the exhaust gas into the interior of the filter box 1. When the exhaust gas is discharged from the exhaust port 3, it will pass through the filter element 603, so that the exhaust gas can be filtered. When the filter element 603 needs to be replaced, the rotating rod 7 can drive the rotating plate 8 to rotate by rotating the connecting plate 9, so that the rotating plate 8 is rotated from the inside of the fixed groove 11 on the filter box 1 to the inside of the fixed hole on the fixing plate 604. At this time, the connecting plate 9 can be pulled forward, so that the rotating rod 7 drives the fixing plate 604 and the positioning block 601 to move upward, and then the positioning block 601 drives the filter element 603 to slide to the outside of the filter box 1, so that the filter element 603 can be easily replaced. The sliding block 602 cannot pass through the limiting plate 5, so that the positioning block 601 will not be completely separated from the filter box 1. The overall structure is simple, which effectively improves the efficiency of replacing the filter element 603, making the overall structure more practical.
