Patent number: 10807053Abstract: Apparatus for mixing a powdered material with a liquid that includes a housing in which a working space having an inner wall is arranged and a rotatably-driven rotor being arranged in the working space. The rotatably-driven rotor includes a blade ring and bars, which are pointing toward the inner wall and are arranged at different positions in a circumferential direction of the rotor. The apparatus also includes a feed opening for the powdered material being arranged above the blade ring and an annular gap connectable to a liquid supply arrangement being arranged below the blade ring. In a direction parallel to an axial direction of the rotor, the bars one of connect to one another or overlap one another.Type: GrantFiled: September 26, 2017Date of Patent: October 20, 2020Assignee: ZEPPELIN SYSTEMS GMBHInventors: Ulrich Jakob, Andreas Hofmann

Patent number: 10723572Abstract: A distribution head of a gravimetric loading system for spreadable bulk materials with a rotatably driven spreader plate, which is composed of a bottom side base plate, which is connected in the central region with the one end of a drive shaft and on which a number of blades evenly distributed on the circumference and with their blade edges approximately in a radially outward direction is arranged. The blade edges of blades are interrupted in the direction of the central axial drive shaft and thus a ring channel extending in the axial direction and free from structures is formed, which channel forms an additional filling and receiving space for the bulk material to be distributed.Type: GrantFiled: August 17, 2018Date of Patent: July 28, 2020Assignee: Zeppelin Systems GmbHInventors: Hermann Baier, Stefan Bier, Christiane Preiss, Amelie Vollmer, Guido Winkhardt

Patent number: 10046925Abstract: Disclosed is a blowing device for a rotary air lock, comprising a flushing gas stream that is fed by a gas supply line (12) in order for adhering material to be flushed and blown out of at least one compartment (20-24) of the rotary air lock (20-24) when said compartment is located next to a product outlet of the rotary air lock. A blowing unit (30), which comprises at least one blowing tube (32) and is located in a feeding shoe (10) that is arranged at the product outlet, directs the flushing gas stream to at least one compartment (20-24) of the rotary air lock.Type: GrantFiled: April 15, 2015Date of Patent: August 14, 2018Assignee: ZEPPELIN SYSTEMS GMBHInventors: Hermann Baier, Ernst Gramm, Robert Müller, Thomas Hilebrand, Björn Feder

Patent number: 9983597Abstract: Method and device for metering a medium from at least one storage tank by a metering device, which has a piston pump, which defines a working chamber with a cylinder and a piston, wherein in a first method step a determined filling quantity of a medium is conveyed via an inlet valve into the working chamber and the determined filling quantity is greater than the quantity to be metered and, in a second method step, the piston reduces the working chamber in size enough that only the quantity to be metered remains, wherein the excess medium flows out of the working chamber, wherein the excess medium flows via the inlet valve back into a ring line, which is connected in a medium-conducting manner to the storage tank and is arranged outside the working chamber.Type: GrantFiled: July 28, 2016Date of Patent: May 29, 2018Assignee: ZEPPELIN SYSTEMS GMBHInventor: Stefan Hertel

Patent number: 9440374Abstract: The invention relates to a device (1) for producing polymer agglomerates, comprising a compounder (2) having a housing (21) and a twin screw (22) arranged therein as well as a plurality of material inlets (3, 4) for admission of a polymer and additives, tempering units for heating the mix comprising polymer and additives, at least one degassing unit (5) and an outlet (23) and an agglomerating vessel (11) having an agglomerating tool (8) and a cooling tool (10). The agglomerating vessel (11) is connected via a connection channel (6) to the outlet (23) of the compounder (2), wherein the twin screw (22) of the compounder (2) is designed as a co-rotating twin Screw (22) and the agglomerating tool (8) of the agglomerating vessel (11) is arranged in the fall direction of the mix below the connection channel (6) and comprises mutually engaging rotors (81) and stators (82) for producing agglomerates of defined particle size. The invention further relates to a method for producing polymer agglomerates.Type: GrantFiled: March 3, 2011Date of Patent: September 13, 2016Assignee: Zeppelin Systems GmbHInventors: Raimund Schwarz, Stephan Poller, Markus Brunkau, Thomas Schill, Dick Van Dijk

Patent number: 8770411Abstract: A method for the separation of fine particles from granulate-like bulk material conveyed in a pipeline as a product flow by means of a compressed air or vacuum conveyance, characterized in that the product flow is radially dispersed at the intake end of a pipe screen integrated in the pipeline in an airtight manner, and aerated there by a cleansing airflow, flowing at an angle to the direction of the dispersed product flow, in the region of a cleansing plane, which deflects the lighter particles, fibers, clusters, dust or similar items carried in the product flow from the trajectory of the heavier granulate, and conveys said into an annular sheath through which the cleansing air flows, from which they are removed by means of a separator.Type: GrantFiled: December 1, 2011Date of Patent: July 8, 2014Assignee: Zeppelin Systems GmbHInventors: Guido Winkhardt, Michael Heep
