[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a diesel engine exhaust gas purification processor, including a housing 1, a cover 2 and a connecting component 5. The housing 1 is installed near the exhaust system of the diesel engine by bolts. The housing 1 serves as the main frame of the exhaust gas purification processor, accommodating the purification device 7, connecting the intake pipe 8 and the cover 2, providing a closed space to ensure that the exhaust gas is fully purified inside. The cover 2 is used to close the top of the housing 1 and can be opened to maintain or replace the internal purification device 7.

[0020] A first ring 3 is installed on the outer shell 1 by welding. The first ring 3 has a rectangular hole 301. A second ring 4 is installed on the cover 2 by welding. The second ring 4 has a mounting hole 401. A connecting component 5 is set on the second ring 4. A limiting post 6 is set on the connecting component 5. The limiting post 6 is T-shaped and passes through the rectangular hole 301. After the limiting post 6 is rotated, it abuts against the bottom surface of the first ring 3.

[0021] The connecting assembly 5 includes a cylinder 501, a circular plate 504, and a spring 505. The cylinder 501 is bolted onto the mounting hole 401. A circular groove 502 is formed on the cylinder 501, and circular holes 503 are formed on both sides of the groove 502. The circular plate 504 is welded onto the outer wall of the limiting post 6. The circular plate 504 is slidably engaged with the circular groove 502, and the limiting post 6 is slidably engaged with the circular holes 503. The circular groove 502 and the circular holes 503 respectively restrict the circular plate 504 and the limiting post 6. The movement trajectory of column 6 ensures stable sliding in the vertical direction. One end of spring 505 abuts against the bottom surface of circular plate 504, and the other end of spring 505 abuts against the bottom inner wall of circular groove 502. A knob 506 is bolted on the limiting column 6. Through the cooperation of connecting component 5, limiting column 6, first ring 3 and rectangular hole 301, quick disassembly and assembly between cover 2 and outer shell 1 can be realized, which saves time compared with traditional bolt connection and facilitates the replacement or maintenance of purification device 7.

[0022] The bottom of the second ring 4 abuts against the top of the first ring 3. The size of the second ring 4 is the same as that of the first ring 3. A sealing ring can be set at the bottom of the second ring 4. The spring 505 is located outside the circular groove 502. The second ring 4 is installed with the connecting component 5 through the mounting hole 401. The first ring 3 is fixed to the cover 2 by cooperating with the limiting post 6 through the rectangular hole 301. The spring 505 provides elastic preload. During installation, the limiting post 6 is inserted into the rectangular hole 301 by compressing the spring 505. After rotation, the elastic force is released, so that the limiting post 6 automatically presses the first ring 3.

[0023] The outer casing 1 houses a purification device 7. The outer wall of the purification device 7 abuts against the inner wall of the outer casing 1. The purification device 7 is the core functional component of the purification processor and consists of a filter, catalyst carrier, support frame, etc. This is existing technology and will not be described in detail here. A connecting ring 201 is installed at the bottom of the cover 2 by welding. The bottom of the connecting ring 201 abuts against the top of the purification device 7. The connecting ring 201 can press the purification device 7 tightly to prevent it from shaking inside the outer casing 1 and ensure that the exhaust gas and purification material are in full contact. The bottom of the cover 2 abuts against the top of the outer casing 1. The abutting setting can prevent unpurified exhaust gas from being discharged directly from the top.

[0024] The bottom of the outer casing 1 is connected to the air intake pipe 8, and the top of the cover 2 is connected to the exhaust pipe 9. The inlet end of the air intake pipe 8 is connected to the exhaust system of the diesel engine, which introduces the exhaust gas discharged by the engine into the purification device 7 inside the outer casing 1 for filtration and catalytic conversion. The exhaust pipe 9 connects the top of the cover 2 to the outside, and discharges the purified gas, forming a complete airflow channel.

[0025] During operation, first place the purification device 7 into the outer casing 1, ensuring that the bottom of the purification device 7 is flush with the inner wall of the outer casing 1. Then, lift the cover 2 and rotate the limiting post 6 using the knob 506 to align the T-shaped head of the limiting post 6 with the rectangular hole 301. Place the cover 2 on top of the outer casing 1, at which point the bottom of the cover 2 is in contact with the top of the outer casing 1, and the connecting ring 201 presses the top of the purification device 7. Then, press the knob 506 downwards. The knob 506 drives the T-shaped head of the limiting post 6 to press down along the rectangular hole 301. As the limiting post 6 slides downwards along the circular hole 503, it drives the circular plate 50... 4. Slide the pin downwards along the circular groove 502 to compress the spring 505 until the T-shaped head of the limiting post 6 passes through the rectangular hole 301. Then rotate the limiting post 6 clockwise by 90° and release the knob 506. The spring 505 rebounds and causes the T-shaped head of the limiting post 6 to come into close contact with the bottom surface of the first ring 3, thus locking the cover 2. When removing the cover 2, press the limiting post 6 down so that it no longer comes into contact with the bottom surface of the first ring 3. Then rotate the limiting post 6 counterclockwise by 90° so that the T-shaped head of the limiting post 6 is aligned with the rectangular hole 301. Pull the limiting post 6 upwards to complete the removal of the cover 2.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
