Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in papermaking, and in particular to a low-energy-consumption and high-efficiency dust removal device for the interior of a papermaking workshop. Background Technology

[0002] Papermaking consists of two parts: pulping and papermaking. The papermaking industry uses wood, straw, reeds, rags, etc. as raw materials, which are cooked under high temperature and pressure to separate cellulose and make pulp. Then, the pulp is dehydrated and shaped into paper. After the paper dries, the cellulose on the surface of the paper will fall off the paper under friction to form paper fibers. These paper fibers are small and disperse into the air.

[0003] In the prior art, Chinese Patent Publication No. CN214813262U discloses a dust removal device for a papermaking production line, including a moving mechanism arranged parallel to one side of the papermaking production line. A dust removal air conveying mechanism and a cantilever are fixedly installed at the upper end of the moving mechanism. The cantilever is located close to the papermaking production line, and a dust collection hood is fixedly installed at the upper end of the cantilever. The dust collection hood is located directly above the papermaking production line. An ion air knife is fixedly installed at the lower outer end of the cantilever via an air knife fixing seat. An air guide plate is fixedly installed at the lower end of the papermaking production line. The ion air knife blows away paper fibers adhering to the papermaking production line by spraying clean gas input from the dust removal air conveying mechanism along the air guide plate to the bottom of the papermaking production line. By setting up the dust collection hood, the input end of the dust removal air conveying mechanism can collect the paper fibers and dust blown off the papermaking production line through the dust collection hood, thereby preventing the paper fibers and dust blown away from the papermaking equipment from escaping into the air and ensuring the cleanliness of the papermaking production line.

[0004] However, in actual use, the production line equipment is widely distributed and paper dust is continuously generated. The dust collection hood cannot cover all the equipment on the line at the same time. When moving to the next station, the paper dust continuously generated by the previous equipment cannot be removed in time. The single-point moving dust removal method is difficult to achieve synchronous dust removal throughout the entire process, which affects the overall dust removal efficiency. The moving mechanism itself requires additional power consumption, which increases the overall energy consumption when the dust removal coverage effect is not ideal, which is not conducive to energy-saving operation. Therefore, it needs to be improved. Utility Model Content

[0018] A further feature of this invention is that the connecting ring is internally threaded with a second bolt, and the number of the second bolts is four.

[0019] By adopting the above technical solution, the second bolt extends into the inside of the edge of the fixing tube, achieving detachable fixing.

[0020] A further feature of this invention is that the inner wall of the dust collector is fixedly connected to a slot frame, and a locking block is engaged with the inner wall of the slot frame.

[0021] By adopting the above technical solution, the card block is snapped into the corresponding card slot frame, making the snap-fit ​​installation more convenient.

[0022] A further feature of this invention is that a filter frame is fixedly connected to the bottom of the card block, and a primary filter is fixedly connected to the inner wall of the filter frame.
