[0003] The exhaust gas treatment devices currently on the market need to be connected to an external exhaust gas pipe when working. However, when the exhaust gas inside the exhaust gas pipe is discharged into the exhaust gas treatment device, the exhaust gas inside the exhaust gas treatment device loses thrust and backflow occurs. Therefore, an exhaust gas treatment device with an internal sealing structure is proposed to solve the above problem. Utility Model Content

[0019] 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.

[0020] See also Figure 1-3 In this embodiment, an exhaust gas treatment device with an internal sealing structure includes an exhaust gas treatment box 1, and a check structure is provided on the top of the exhaust gas treatment box 1 to prevent exhaust gas leakage.

[0021] The non-return structure includes an air duct 2 fixedly installed on the top of the exhaust gas treatment box 1, through which the exhaust gas is guided into the exhaust gas treatment box 1 for treatment. The air duct 2 is located at one end close to the right side of the exhaust gas treatment box 1, and the air duct 2 is through-connected with the exhaust gas treatment box 1. A built-in support frame 3 is fixedly installed inside the air duct 2, and the built-in support frame 3 is located at the waist position of the air duct 2. A T-shaped rod 4 that penetrates to the bottom of the built-in support frame 3 is slidably installed on the top of the built-in support frame 3, and the T-shaped rod 4 is restricted by the built-in support frame 3 to rise and fall inside the air duct 2.

[0022] The top of the built-in support frame 3 is movably installed with a No. 1 spring 5 which is mounted on the outside of the T-shaped rod 4. The No. 1 spring 5 is located at the bottom of the T-shaped rod 4. A circular rubber pad 6 is fixedly installed at the bottom of the T-shaped rod 4. An air blocking ring 7 which is mounted on the outside of the circular rubber pad 6 is fixedly installed on the outside of the air guide pipe 2. The circular rubber pad 6 slides up and down inside the air blocking ring 7. The circular rubber pad 6 is located at one end that is opened into the bottom of the air blocking ring 7. The air blocking ring 7 is located at the bottom of the built-in support frame 3. The diameter of the circular rubber pad 6 is larger than the inner diameter of the air blocking ring 7. The No. 1 spring 5 is unfolded to push the T-shaped rod 4 upward, and then the T-shaped rod 4 pulls the circular rubber pad 6 to be stuck in the inside of the air blocking ring 7. When the exhaust gas flows under the top line of the air guide pipe 2, the circular rubber pad 6 will be pushed down. At this time, the exhaust gas will flow into the inside of the exhaust gas treatment box 1 from the side of the circular rubber pad 6. When there is no exhaust gas flowing at the top of the air guide pipe 2, the exhaust gas inside the exhaust gas treatment box 1 will push the circular rubber pad 6 to rise and be stuck in the inside of the air blocking ring 7. At this time, the exhaust gas cannot flow out.

[0023] An internal threaded tube 8 is fixedly installed on the top of the air duct 2, and the installed internal threaded tube 8 is convenient for docking with the external exhaust pipe. A metal mesh 9 is fixedly installed inside the exhaust gas treatment box 1. The metal mesh 9 is located on the left side of the air duct 2. The large particles in the exhaust gas are blocked and filtered by the installed metal mesh 9. An atomizing nozzle 10 is fixedly installed on the top of the inner cavity of the exhaust gas treatment box 1 and is located on the right side of the metal mesh 9. The water spraying end of the atomizing nozzle 10 faces the metal mesh 9. After the external water source is connected to the water inlet pipe on the top of the atomizing nozzle 10, water starts to spray. After spraying on the inside of the exhaust gas treatment box 1, the exhaust gas is cooled down and the dust in the exhaust gas can also be degraded.

[0024] A U-shaped tube 11 is fixedly installed inside the lower bottom wall of the exhaust gas treatment box 1 and penetrates therein. The U-shaped tube 11 penetrates to the right side of the exhaust gas treatment box 1. The sewage inside the exhaust gas treatment box 1 is guided to the outside through the installed U-shaped tube 11. A solenoid valve located on the right side of the exhaust gas treatment box 1 is fixedly installed outside the U-shaped tube 11. The flow state of the U-shaped tube 11 is controlled by the solenoid valve. Two limiting side plates 12 are fixedly installed inside the exhaust gas treatment box 1. Both limiting side plates 12 are located on the left side of the metal mesh 9. A lifting plate 13 is slidably installed between the two limiting side plates 12. The lifting plate 13 is limited to the bottom of the inner cavity of the exhaust gas treatment box 1 by the two limiting side plates 12. The lifting plate 13 is lifted and lowered. A plurality of No. 2 springs 14 are fixedly installed at the bottom of the lowering plate 13, and the plurality of No. 2 springs 14 are fixedly installed at the bottom of the inner cavity of the exhaust gas treatment box 1. The plurality of No. 2 springs 14 are unfolded to squeeze the lifting plate 13 to rise, and a mounting frame 15 that penetrates into the interior of the upper top wall of the exhaust gas treatment box 1 is movably installed on the top of the lifting plate 13. The outer portion of the mounting frame 15 is square-shaped, and the mounting frame 15 is connected to the upper top wall of the exhaust gas treatment box 1 by sliding up and down. An activated carbon filter element 16 is fixedly installed inside the mounting frame 15, and fine particles in the exhaust gas are filtered by the installed activated carbon filter element 16, and the activated carbon filter element 16 and the mounting frame 15 are lifted to the top of the exhaust gas treatment box 1 through the lifting plate 13.

[0025] A flip plate located on the top of the mounting frame 15 is rotatably installed on the top of the exhaust gas treatment box 1, and a plug plate is slidably installed on the top of the exhaust gas treatment box 1. The plug plate is located on the top of the flip plate. After the flip plate cover is rotated forward on the top of the mounting frame 15, the mounting frame 15 can be restricted. At this time, the mounting frame 15 cannot pop out of the outside of the exhaust gas treatment box 1. The flip plate can be restricted by moving the plug plate to the left to the top of the flip plate.

[0026] The working principle of the above embodiment is:

[0027] When in use, first connect the external waste pipe with the internal threaded tube 8. At this time, the external exhaust gas enters the interior of the air duct 2. The exhaust gas entering the air duct 2 pushes the circular rubber pad 6 down. At this time, the exhaust gas will flow into the interior of the exhaust gas treatment box 1 from the side of the circular rubber pad 6. When there is no exhaust gas flowing at the top of the air duct 2, the exhaust gas inside the exhaust gas treatment box 1 will push the circular rubber pad 6 to rise and get stuck in the air blocking ring 7, making it impossible for the exhaust gas to flow out. The exhaust gas entering the exhaust gas treatment box 1 is sprayed with water by the atomizing nozzle 10 to cool down and take away the dust. Then, the large particles are filtered out by the metal mesh 9 and the fine particles are filtered out by the activated carbon filter element 16. Finally, the filtered gas is discharged to the outside from the left side of the exhaust gas treatment box 1. When the installation frame 15 needs to be replaced, the plug plate can be pulled to the right to make the flip plate lose the restriction. Then, multiple No. 2 springs 14 can be unfolded to push the installation frame 15 and the activated carbon filter element 16 on the top of the lifting plate 13 to pop out of the outside of the exhaust gas treatment box 1.
