Description

Technical Field

[0001] The invention relates to the technical field of exhaust gas treatment equipment, and in particular to an exhaust gas filter. Background Art

[0002] In exhaust gas treatment, filters are often used to filter dust particles in the exhaust gas, and different filters use different fillers, among which the filler rope is a filler material that is strung or spun from a center rope and other plastic or fiber materials.

[0003] In the Chinese utility model patent with authorization announcement number CN213171651U, a filling rope with good toughness is disclosed, including a mounting rod, a mounting rod is arranged on the top of the rope body, and a mounting slide groove is arranged on the bottom surface of the mounting rod, and a mounting slider is arranged at the connection between the top of the rope body and the mounting slide groove, the mounting slider is slidably connected to the mounting slide groove, one end of the mounting slide groove is connected to the outside, and a rubber plug is clamped at one end of the mounting slide groove. In the utility model, a limiting protrusion is designed on the top of the rope body, and a mounting rod with a mounting slide groove is designed. The limiting protrusion is fixed by clamping in the mounting slide groove, and the spacing between the rope bodies can be conveniently adjusted by sliding the mounting slider, so that the seal can be conveniently adjusted, and the rope body is very convenient to install and disassemble. In addition, a retractable telescopic rod is designed on the mounting rod, so that the overall length of the mounting rod can be adjusted, which is convenient for adjustment according to the size of the installation site, which is more convenient.

[0004] Although the above patent can adjust the distance between the rope bodies, the above-mentioned filler rope has a single rope structure when in use, which makes the filtering range very limited. If the distance between the rope bodies is increased, the filtering effect of the filler rope will be affected. Moreover, if multiple layers of filler ropes are required for filtering, multiple mounting rods must be installed. At this time, in order to ensure the filtering effect, the distance between the rope bodies on each mounting rod needs to be adjusted multiple times, which is very inconvenient to operate. Moreover, the distance between two adjacent mounting rods also needs to be adjusted, and there is no connection between the two mounting rods. When in use, each mounting rod needs to be assembled, which is cumbersome, time-consuming and labor-intensive. Summary of the invention
