Abstract
An apparatus for feeding bulk material includes a housing which accommodates a rotor arranged between an inlet port and an outlet port of the housing and having a plurality of radially extending vanes. The vanes are fixed on a shaft and provided with sealing strips for sealing the vanes against the housing. For compensating occurring wear and maintaining the sealing action, the sealing strips are corrected by an adjusting bar with two spaced conical sufaces which cooperate with push rods having one end lying against the conical surfaces and another end in force-locking connection with the sealing strips.
Claims15
Apparatus for feeding bulk material;
- comprising:
- a housing provided with inlet means and outlet means;
- a rotor accommodated within said housing and having a shaft and a plurality of radially extending vanes supported on said shaft to define compartments for transporting the bulk material from said inlet means to said outlet means;
- sealing means disposable in said vanes for sealing said vanes toward said housing, said sealing means including a sealing strip and a support which is interlocked with said sealing strip and provided with at least one radial bore;
- adjusting means acting on said sealing means for maintaining the sealing action at said housing and including an adjusting bar which is guided within said shaft for axial displacement thereof and has at least two conical surfaces spaced from each other in axial direction, and push rods provided in said vanes and spaced from each other in such a manner that their one end abuts said conical surfaces and their other end bears against said sealing means;
- and
- spring means urging said sealing means radially in direction toward said shaft to prevent disengagement of said sealing means from said vanes during rotation of said rotor, said spring means including a screw traversing said radial bore of said support and being threadably engaged in said vanes, and a compression spring extending in said radial bore with their one end bearing against said support and their other end supported by said screw.

A rotary sluice for feeding bulk material;
- comprising
- a housing provided with a top inlet port and a bottom outlet port;
- a rotor accommodated within said housing and having a horizontal shaft and a plurality of radially extending vanes supported on said shaft to define compartments for transporting the bulk material in defined quantities from said inlet port to said outlet port;
- sealing means disposable in said vanes for sealing said vanes toward said housing, said sealing means including a sealing strip and a support which is interlocked with said sealing strip and provided with at least one radial bore;
- adjusting means acting on said sealing means for maintaining the sealing action at said housing and including an adjusting bar which is guided within an axial bore of said shaft for axial displacement thereof and has at least one conical surfaces spaced from each other in axial direction, and push rods guided in bores of said vanes in such a manner that their one end abuts said conical surfaces and their other end bears against said sealing means, and
