Description

Technical Field

[0001] This utility model relates to the field of DPF honeycomb ceramic technology, specifically a DPF honeycomb ceramic carrier for diesel engine filtration. Background Technology

[0002] DPF honeycomb ceramic, or diesel particulate filter, is a structural component for highly efficient filtration of particulate matter (PM). Here is a detailed description: Basic Form: The DPF honeycomb ceramic is cylindrical with alternating pores on the end faces, consisting of hundreds of small straight channels with a diameter of 0.1–0.2 mm. Each channel has pores on both sides for air permeability. Wall Flow Structure: The wall flow structure of the DPF can be divided into two types: single-wall (without filling) and double-wall (with filling). The pores in the partition walls are arranged radially, forming a large number of small holes that trap solid particles through wall flow filtration. When diesel engine exhaust enters the DPF, the clean air (containing HC, CO, etc.) is discharged through the inner wall of the DPF via adjacent channels; while the particulate matter (PM) in the exhaust is trapped within the channels or the honeycomb walls, thus achieving the purpose of filtration.

[0003] According to patent announcement number CN215761867U published on the China Patent Network, this utility model discloses a honeycomb ceramic carrier for exhaust gas of a China VI emission standard low back pressure high collection efficiency diesel engine. The carrier includes a honeycomb ceramic carrier with an inner ring layer inside. A hexagonal reinforcing honeycomb edge layer is installed on the outer side of the inner ring layer. A left half-arc-shaped strength support frame is installed at the middle position of one side of the inner ring layer. This utility model adds an inner ring layer, and the left and right half-arc-shaped strength support frames are installed at the middle positions of both sides of the inner ring layer. The connection between the left and right half-arc-shaped strength support frames reinforces the inner ring layer from the center, increasing the overall support strength of the honeycomb ceramic carrier. This makes it less prone to damage during transportation or manufacturing. The inner ring layer also reinforces the weakest parts located on the sides, increasing the strength of the outer structure and extending its service life.

[0004] Diesel engine filtration requires the use of DPF honeycomb ceramic carriers. However, most DPF honeycomb ceramic carriers on the market are usually one-piece, which means that the entire DPF honeycomb ceramic carrier needs to be scrapped when it is replaced or disassembled, which increases the economic burden on users and does not have high efficiency and environmental protection performance, thus affecting the efficient use of DPF honeycomb ceramic carriers.

[0005] Therefore, it is necessary to design and modify the DPF cell ceramic carrier to effectively prevent the need for complete scrapping when replacing or disassembling the DPF cell ceramic carrier. Utility Model Content

The support block 45 is fixedly connected to the back of the sealing plate 42 and is sleeved on the surface of the screw 44. The transmission block 46 is threadedly connected to the surface of the screw 44. The transmission plate 47 is fixedly connected to the right side of the transmission block 46, and the locking rod 48 is fixedly connected to the back of the transmission plate 47. The back of the locking rod 48 extends through the interior of the DPF honeycomb ceramic carrier 3.

[0027] refer to Figure 2 The surface of the rotating block 43 is provided with anti-slip texture 5, which is used in conjunction with the rotating block 43.

[0028] As a technical optimization of this utility model, the anti-slip texture 5 makes it easier for users to rotate the rotating block 43, thus improving user comfort.

[0029] refer to Figure 2 A slider 6 is fixedly connected to the left side of the transmission block 46, and a sliding groove 7 is provided on the left side of the inner wall of the mounting groove 41. The slider 6 and the sliding groove 7 are used in conjunction.

[0030] As a technical optimization of this utility model, the sliding block 6 and the sliding groove 7 can limit the transmission block 46 and prevent the transmission block 46 from rotating when moving.

[0031] refer to Figure 2 A guide rod 8 is fixedly connected to the rear side of the inner wall of the mounting groove 41. The guide rod 8 passes through the transmission plate 47 and is slidably connected to the transmission plate 47.

[0032] As a technical optimization of this utility model, the guide rod 8 can provide auxiliary support for the transmission plate 47 and prevent the transmission plate 47 from tilting when moving.

[0037] The working principle and usage process of this utility model are as follows: In use, firstly, the user installs the DPF honeycomb ceramic carrier 3 into the inside of the locking block 2. Then, the user rotates the rotating block 43 through the anti-slip texture 5. The rotating block 43 drives the screw 44 to rotate. The screw 44 is connected to the transmission block 46 through a thread, which drives the transmission block 46 to move backward on the surface of the screw 44. The transmission block 46 drives the transmission plate 47 to move backward. The transmission plate 47 drives the locking rod 48 to move backward. The locking rod 48 enters the inside of the DPF honeycomb ceramic carrier 3, thereby fixing the DPF honeycomb ceramic carrier 3. The reverse operation allows for quick replacement and disassembly, preventing the economic burden of overall disassembly.

[0038] In summary, this diesel engine filter DPF honeycomb ceramic carrier, by adding functionality for partial removal and replacement and enhancing environmental performance, enables efficient removal of the DPF honeycomb ceramic carrier, preventing the need for complete scrapping during replacement and thus solving the problem of requiring complete scrapping of the DPF honeycomb ceramic carrier during replacement and removal.
