Air scoop-cyclone filter assembly
An air scoop-cyclone filter assembly having an air scoop for guiding untreated air, which including an inlet opening, a deflection area for deflecting untreated air and an outlet opening, and having a cyclone filter for cleaning untreated air, which is connected downstream of the air scoop in the flow direction and is connected in an airtight manner to the air scoop A perforated plate is arranged in the cyclone filter as a filter inlet opening. The perforated plate has a first passage area having a high number of holes, a second passage area having a low number of holes at the geodetically deepest point, and a baffle plate. The baffle plate distributes the untreated air flow through the first and second passage area and, with the outer wall of the air scoop, forms a collecting chamber that stabilizes the flow.
1. An air scoop-cyclone filter assembly comprising: an air scoop for guiding untreated air, the scoop comprises an inlet opening, a deflecting area for deflecting the untreated air, and an outlet opening; and a cyclone filter for cleaning the untreated air, the cyclone filter being installed downstream from the air scoop and connected to the air scoop in an airtight manner, wherein a perforated plate is arranged in the cyclone filter to serve as a filter inlet opening, the perforated plate comprising a first pass-through area with a large number of holes, a second pass-through area with a smaller number of holes at a geodesically lowest point, and a baffle plate, wherein the baffle plate divides the untreated air stream between the first pass-through area and the second pass-through area and cooperates with an outside wall of the air scoop to form a nonturbulent collecting space.
2. The air scoop-cyclone filter assembly according to claim 1 , wherein the cyclone filter comprises a first outlet opening for charging air and a second outlet opening for dust discharge, and, with respect to a flow of air, the collecting space is connected to the second outlet opening via the second pass-through area.
3. The air scoop-cyclone filter assembly according to claim 2 , wherein a guide plate for guiding the untreated air is arranged in the deflecting area of the air scoop.
4. The air scoop-cyclone filter assembly according to claim 2 , wherein the cyclone filter has a two-stage design.
