Method and device for conveying goods to be conveyed with a cellular wheel sluice

Abstract

A method for conveying goods to be conveyed with a cellular wheel sluice, where in a housing, the goods to be conveyed are conveyed with rotor blades of the rotating cellular wheel, and sealing lips of the rotor blades abut against at least one sealing surface of the housing, and where during the transport of certain goods to be conveyed, a sealing surface and/or sealing lips can be used which are formed from an abrasive material that is contained in the goods to be conveyed.

1 . A method of conveying goods to be conveyed with a cellular wheel sluice, comprising in a housing, conveying goods to be conveyed by way of a plurality of rotor blades of a rotating cellular wheel, abutting sealing lips of the rotor blades against at least one sealing surface of the housing, and during the transport of goods to be conveyed, using at least one of a sealing surface or sealing lips which are made of an abrasive material that is contained in the goods to be conveyed. 
     
     
         2 . The method of conveying goods according to  claim 1 , wherein as an abrasive material of the sealing or of the sealing lips using one of polyethylene, polypropylene, polystyrene, polymethylmethacrylate, polyamides, polyester (polycarbonate and polyethylene terephthalate), polyethylene glycol, polyoxymethylene, star polymers, polyester urethane rubber, silicone, fluorosilicone, and a combination thereof. 
     
     
         3 . The method of conveying goods according to  claim 1 , and as the sealing lips, using a lamellar or bristle structure. 
     
     
         4 . The method of conveying goods according to  claim 1 , where as the sealing lips, using packs of foil elements of an abrasive material. 
     
     
         5 . The method of conveying goods according to  claim 4 , wherein edges of the foil elements slide along the sealing surface. 
     
     
         6 . The method of conveying goods according to  claim 4 , wherein edges of the foil elements slide along the sealing surface perpendicularly to the direction of motion of the rotor blades. 
     
     
         7 . A cellular wheel sluice for conveying goods to be conveyed, comprising a housing with at least one sealing surface and a cellular wheel rotatably arranged therein, the cellular wheel comprising several rotor blades with sealing lips abutting against the sealing surface for sealing, and depending on the goods to be conveyed, the cellular wheel sluice is provided with sealing lips and/or at least one sealing surface formed of a material that is contained in the goods to be conveyed. 
     
     
         8 . The cellular wheel sluice according to  claim 7 , wherein the sealing surface and/or the sealing lips comprise a material of polyethylene, polypropylene, polystyrene, polymethylmethacrylate, polyamides, polyester (polycarbonate and polyethylene terephthalate), polyethylene glycol, polyoxymethylene, star polymers, polyester urethane rubber, silicone, fluorosilicone, or a combination thereof. 
     
     
         9 . The cellular wheel sluice according to  claim 7 , wherein the sealing lips comprise a lamellar and/or bristle structure. 
     
     
         10 . The cellular wheel sluice according to  claim 7 , wherein the sealing lips comprise packs of foil elements. 
     
     
         11 . The cellular wheel sluice according to  claim 10 , wherein the foil elements are arranged perpendicularly to the direction of motion of the rotor blades. 
     
     
         12 . The cellular wheel sluice according to  claim 10 , wherein the ends of the foil elements and the sealing surface include an angle which is within a range of 45° to 90°. 
     
     
         13 . The cellular wheel sluice according to  claim 10 , wherein the foil elements have a thickness within a range of 50 μm to 500 μm. 
     
     
         14 . The cellular wheel sluice according to at least one of  claim 7 , wherein the sealing surface is arranged such that it at least partially encloses the cellular wheel. 
     
     
         15 . The cellular wheel sluice according to  claim 7 , wherein the sealing lips are mounted to the rotor blades to be exchangeable. 
     
     
         16 . The cellular wheel sluice according to  claim 12 , wherein the angle is within a range of 80° to 90°. 
     
     
         17 . The cellular wheel sluice according to  claim 13 , wherein the thickness is within a range of 190 μm to 350 μm.
