Patent number: 7762717Abstract: In a device for processing bulk materials, for example by mixing, shredding, metering and/or screening, with a container (40) and an implement (30) driven therein about a horizontal axis by an external rotary drive (10), it is proposed as claimed in the invention that, arranged between the container (40) and the rotary drive (10), is a connection unit (20), to which the container (40) is detachably fastened, in which a shaft (33) of the implement (30) is detachably retained and is detachably attached to the rotary drive (10), and in which a labyrinth seal (50) is loosely accommodated for the purpose of sealing the container (40) against the implement shaft (33).Type: GrantFiled: January 6, 2006Date of Patent: July 27, 2010Assignee: Gericke AGInventors: André Röhm, Ralf Weinekötter, Peter Brechbühler, Heinz Diethelm

Patent number: 6287056Abstract: In a method of operating a pulse flow conveying installation (10), which is intended for the conveying of a solid material (33), present in the form of bulk material, by means of a conveying gas, in which pulse flow conveying installation (10) an alternating sequence of solid material pulses (27) and conveying gas pulses (28) is generated by first means (13, . . . , 21) in the conveying conduit (25) and is pressed through the conveying conduit (25), choking is reliably prevented in that the conveying pressure is regulated, and in that to regulate the conveying pressure in the conveying conduit (25), the quantity of the conveying gas flowing on a time average basis through the conveying conduit (25) is altered in relation to the quantity of the solid material conveyed on a time average basis through the conveying conduit (25).Type: GrantFiled: November 20, 1998Date of Patent: September 11, 2001Assignee: Gericke AGInventor: Georg Szikszay

Patent number: 6109779Abstract: A continuous mixer (10) comprises an elongated mixing container (11), which has an inlet opening (14) at one end for feeding in the basic components to be mixed and which encloses a mixing space (12), which merges at the other end into a discharge region (22) for the delivery of the mixed product, and in which mixing container (11) there is arranged a mixing tool (13), which is rotatable about an axis (41), is driven by a drive (18, 40) and mixes together the basic components fed into the inlet opening (14) and at the same time transports them to the discharge region (22). In such a mixer, improved control of the mixing conditions is achieved by an adjustable discharge opening (19) adjustable in size being arranged between the discharge region (22) and the mixing space (12).Type: GrantFiled: January 25, 1999Date of Patent: August 29, 2000Assignee: Gericke AGInventors: Ralf Weinekotter, Lukas Hiltbrunner

Patent number: 5149229Abstract: A method and apparatus for pneumatically conveying material in form of granular solids or the like includes a feeder sending the material under pressure and addition of carrier gas in a transport pipe such that its cross sectional area is only partly filled with the material. The transport pipe is subdivided by vibration compensators into several pipe sections of a length of up to several meters which are subjected to vibrations so that the wall friction between the material and the transport pipe is reduced in such a manner that at a flow pattern similar to a strand/crown flow up to a plug flow the carrier gas is charged with material to a high degree and a material layer forming at the pipe bottom is also conveyed. The pipe sections may be made of a rigid vibrating material or may be made in form of a flexible hose which is mounted on a support and either directly or indirectly subjected to vibrations.Type: GrantFiled: October 3, 1989Date of Patent: September 22, 1992Assignee: Gericke AG, MaschinenfabrikInventors: Willi Gericke, Karl-Ernst Wirth, Wolfgang Siebenhaar

Patent number: 4496083Abstract: Within a loose or bulk good container there is arranged a loosening wheel which is wider than a discharge spiral. The loosening wheel is secured by a wheel holder device at a removable wall portion of the container. The removable wall portion is arranged transversely with respect to the discharge spiral and is fixedly connected with an outlet or discharge connection of the container. During exchange of the discharge spiral and/or the loosening wheel there can be removed as a structural unit or assembly from the container wall the removable wall portion together with the outlet or discharge connection, the wheel holder device and the loosening wheel, and such structural unit can be replaced by a different structural unit containing the corresponding elements but of different dimensions.Type: GrantFiled: May 14, 1982Date of Patent: January 29, 1985Assignee: Gericke AGInventors: Hermann Gericke, Robert Schavilje

Patent number: 4029133Abstract: A process for mechanically emptying powdery substances into a container, while the filling space rotates during the filling step. The invention relates further to a device for carrying out the process. The device has a cover that can be tightly set upon the filling hole of a container and co-rotates therewith during the filling step. The cover is provided with centrally arranged filling and air outlet channels, forming an annular space with the surrounding cover. The cover is provided with means that increases the filling space volume during filling, and reduces the volume of the filling space by the additional volume after the filling process.Type: GrantFiled: October 17, 1975Date of Patent: June 14, 1977Assignee: Gericke AG, MaschinenfabrikInventors: Robert Rottermann, Marcel Rottermann
