Swinging Hatch
Swinging Hatch
Swinging hatches can operate at the sub-pressure and at the over-pressure side of an installation - it depends on type of applied solution (hatches without a drive at the sub-pressure side, hatches with a drive at the sub-pressure / overpressure side). Standard device we offer is a double hatch.
Features
- Device comprises a body and inlet and outlet flanges (square section)
- Inside the body there are two throats, through hole of which is closed by means of rotary hatches. They are equipped with levers with metal loads on them
- Dusts, which go through the device, because of its weight, open the first hatch and, after closing it, another one. Synchronization of opening of the hatches and pressure on the throat is adjusted by relevant setting of loads on both of the hatches.
Double swinging hatch with a drive
In case of this solution there takes place enforced synchronization of swinging hatches opening. It takes place by means of motor-reducer assembly on axis of which there are fastened special cams. Their movement warrants setting of hatches - while one closes upper throat, the second one is open and vice versa. Such operation warrants 100% removal of dust without decompression. In case of a few solutions and additionally, in case of limited space, apart from double-hatch we apply single hatches.

The Swinging Hatch is a dust-handling device that controls dust passage through an installation using rotary hatches. In its standard double-hatch arrangement, dust weight opens the first hatch before the second, while adjustable metal loads set their timing and pressure on the throats. Different hatch types operate on the sub-pressure or over-pressure side, and driven hatches are available for either side.
- Square-section body has inlet and outlet flanges
- Motor-reducer assembly and cams enforce hatch synchronisation
- As one hatch closes the upper throat, the other opens
- Driven double hatches remove 100% of dust without decompression
- Single hatches are used in some arrangements and where space is limited
