Description

Technical Field

[0001] This utility model relates to the field of diesel engine DPF ceramic technology, specifically to a particulate filter device for diesel engine DPF ceramic. Background Technology

[0002] A diesel particulate filter (DPF) can reduce engine soot by more than 90%. The captured particulate matter is then completely burned off during vehicle operation. Its basic working principle is as follows: If the diesel particulate filter is coated with metals such as platinum, rhodium, and palladium, the black smoke containing carbon particles emitted from the diesel engine enters the particulate filter through a special pipe. Inside, a densely packed bag filter adsorbs the carbon particles onto a filter made of metal fiber felt. When the adsorbed particles reach a certain level, the burner at the tail end automatically ignites and burns the adsorbed carbon particles, turning them into harmless carbon dioxide that is emitted during the emission process.

[0003] When diesel engines are in use, particulate filters are needed to treat the exhaust gas in order to prevent it from polluting the environment. However, most existing particulate filters require users to use tools and bolts to install and fix them in place. The installation process is cumbersome, and bolts and other parts and tools can easily scratch the particulate filter during installation. Utility Model Content

The left side of the locking block 6 extends into the interior of the vertical block 4. The input end of the filter device 2 is fixedly connected to a disc 7. The front of the disc 7 is slidably connected to a flange 8. The inner wall of the flange 8 is fixedly connected to a connecting pipe 9. A sleeve 10 is fitted on the surface of the connecting pipe 9. A ring 11 is provided inside the disc 7. A connecting rod 12 is fitted on the inner wall of the ring 11. The back of the connecting rod 12 extends into the back of the disc 7 and is fixedly connected to a support ring 14. A positioning block 13 is slidably connected to the surface of the ring 11. The outer side of the positioning block 13 extends into the interior of the sleeve 10.

[0022] As a technical optimization of this utility model, the connection groove 15 can limit the position of the connecting rod 12, the ring 11 and the support ring 14, and the positioning groove 16 can position the position of the sleeve 10 to prevent the flange 8 from falling off the disc 7.

[0023] refer to Figure 4 The front of the disc 7 has a sliding hole 17, and a slider 18 is slidably connected to the inner wall of the sliding hole 17. The bottom of the slider 18 is fixedly connected to the inner wall of the disc 7.

[0024] As a technical optimization of this utility model, the position of the positioning block 13 can be positioned by the cooperation of the sliding hole 17 and the slider 18, so as to prevent the positioning block 13 from shifting when it moves.

[0025] refer to Figure 4 A tension spring 19 is fixedly connected to the inner wall of the sliding hole 17 near the ring 11. The outer side of the tension spring 19 is fixedly connected to the side of the slider 18 near the ring 11. A groove 20 is provided on the surface of the ring 11 to cooperate with the positioning block 13.

[0026] As a technical optimization of this utility model, the setting of the tension spring 19 can facilitate the reset of the positioning block 13, allowing the positioning block 13 to disengage from the positioning groove 16. The setting of the groove 20 can facilitate the inward movement of the positioning block 13.

[0027] refer to Figure 2 The surface of the vertical block 4 is provided with a slot 21 for use with the card block 6. A spring piece 22 is fixedly connected to the right side of the card block 6, and the right side of the spring piece 22 is fixedly connected to the inner wall of the disc 7.

[0028] As a technical optimization of this utility model, the position of the filter device 2 can be positioned by the setting of the slot 21 to prevent the filter device 2 from falling off the mounting plate 1. The setting of the spring piece 22 can facilitate the reset of the locking block 6 and the pulling block 5, and at the same time prevent the locking block 6 and the pulling block 5 from moving when they do not need to move.

[0029] refer to Figure 3 Limiting blocks 23 are provided on both sides of the front of the disc 7. Bolts are provided on the front of the limiting blocks 23. The threaded end of the bolts extends to the back of the limiting blocks 23 and is threadedly connected to the front of the disc 7.

[0030] As a technical optimization of this utility model, the positions of the disc 7 and the flange 8 can be limited by the cooperation of the limiting block 23 and the limiting groove 24, so as to prevent the flange 8 from falling off the disc 7.

[0031] The working principle and usage process of this utility model are as follows: When in use, the user pulls the pull block 5 to the right. The pull block 5 moves to the right, causing the locking block 6 to move to the right, so that the locking block 6 disengages from the locking groove 21. The locking block 6 moves to the right and compresses the spring 22. Then, the user pulls the sleeve 10 forward, so that the sleeve 10 disengages from the disc 7 and the flange 8. After that, the user pulls the support ring 14 backward, so that the connecting rod 12 disengages from the connecting groove 15. At the same time, the user rotates the support ring 14 clockwise. The rotation of the support ring 14 causes the connecting rod 12 and the ring 11 to rotate, so that the rebound force of the tension spring 19 causes the positioning block 13 to move inward, so that the positioning block 13 disengages from the positioning groove 16 and simultaneously causes the positioning block 13 to engage with the groove 20. At this time, the user pulls the filter device 2 downward, so that the vertical block 4 disengages from the protrusion 3 and the limiting block 23 disengages from the limiting groove 24. At this time, the filter device 2 can be disassembled. The operation is reversed during installation to install and fix the position of the filter device 2.

[0032] In summary, this ceramic particulate filter for diesel engine DPF, through the coordinated use of mounting plate 1, filter device 2, protrusion 3, vertical block 4, pull block 5, locking block 6, disc 7, flange 8, connecting pipe 9, sleeve 10, ring 11, connecting rod 12, positioning block 13, and support ring 14, solves the problem that most existing particulate filters require users to use tools and bolts to install and fix the particulate filter, which is cumbersome and prone to scratching the particulate filter during installation.
