This invention belongs to the field of ironmaking dust removal technology, specifically a dust removal device for the blast furnace ironmaking tapping area. It includes a frame and an inlet pipe, an outlet pipe, a filter box mechanism, a screen changing mechanism, and a fan mounted on the frame. The filter box mechanism includes a first box, a second box, and an opening / closing drive device. The screen changing mechanism includes a translation support, a translation drive device, a rotating support, a rotating drive device, and filter plates. The rotation of the rotating support allows one of the two filter plates to be selectively positioned between the first and second boxes, with the first and second boxes clamping the filter plate between them to form a sealed structure. This invention also provides a method for replacing the filter plates in the aforementioned blast furnace ironmaking tapping area dust removal device. This invention can automatically replace the in-use filter plates with spare ones, greatly reducing the downtime of the dust removal device and offering advantages such as good dust removal effect, low cost, and small space occupation.

This application relates to the field of lawnmower technology, and in particular to a high-efficiency heat-dissipating lawnmower drive mechanism and a lawnmower. The high-efficiency heat-dissipating lawnmower drive mechanism includes a first mounting box, a transmission assembly, a stator, a rotor, a second mounting box, a circuit board, and an airflow generating assembly. Compared to existing high-efficiency heat-dissipating lawnmower drive mechanisms, mounting the stator, rotor, and circuit board on the same side of the first mounting box, with relatively close proximity, facilitates coordinated heat dissipation. The airflow generating assembly drives the airflow around the rotor, rapidly expelling hot air from the stator through heat dissipation holes, ensuring effective heat dissipation for both the stator and rotor. The airflow generating assembly also drives the airflow around multiple heat dissipation fins, rapidly cooling the heat dissipation fins and consequently rapidly cooling the circuit board, ensuring effective heat dissipation for the circuit board.
