Device for making a multi-components product material

Abstract

A device for making of a multi-components product material. The device includes a processing and homogenizing chamber for primary particle components. The chamber includes at least two sets of rotary shovels, which rotate in parallel in a mutually counter-rotating, homogenizing mode, inlet(s) into the chamber for at least one secondary component in a fluid state and/or fine particulate material state, which interacts with the primary components while they are moved around in the chamber by sets of the shovels, and an outlet in the chamber to allow the primary and secondary components to leave the chamber as the multi-component product material.

What is claimed is: 
     
         1 . A device for making of a multi-components product material, comprising:
 a processing chamber with at least one supply inlet for primary particle components, said chamber configured to homogenize the primary components;   at least two sets of rotary shovels, each set with a plurality of rotary shovels on a common rotary shaft in order to homogenize the primary components in the chamber, the rotary shafts of the at least two sets of rotary shovels being caused to rotate in parallel in a mutually counter-rotating, homogenizing mode;   inlet(s) into the chamber for at least one secondary component in a fluid state and/or fine particulate material state, e.g. powder, and which is to interact with said primary components in the chamber while the primary components are moved about in the processing chamber by sets of the rotary shovels, and   an outlet in a bottom region of the processing chamber to allow the primary and secondary components to be discharged from the chamber as the multi-component product material,   wherein at least one heating agent inlet into the processing chamber is provided to let a heating agent enter the processing chamber to heat at least partly primary components therein and to dry off any unwanted liquid moisture from the primary components,   wherein the device is configured to process primary particle components and fine particulate materials which are made from coke, and configured to process secondary component in fluid state which is pitch, and   wherein the bottom region outlet is directly upstream of a product finalizing stage being a pressure operated mould to yield a final product of said multi-component product material being an electrode.   
     
     
         2 . The device of  claim 1 , wherein the heating agent is superheated steam or inert gas. 
     
     
         3 . The device of  claim 1 , wherein the chamber inlets for the secondary component(s) provide for delivery of said secondary component(s) as a sprayed liquid. 
     
     
         4 . The device of  claim 1 , wherein the processing chamber and the at least two sets of rotary shovels are configured to process the primary components which are a mixture of differently sized particles. 
     
     
         5 . The device of  claim 1 , wherein multiple inlets into the processing chamber are provided to enable multiple second components to be delivered in succession to the processing chamber to yield multiple layers of second components on the primary components. 
     
     
         6 . The device of  claim 1 , wherein a heating agent composition status and property sensor is located upstream of the at least one heating agent inlet to the processing chamber. 
     
     
         7 . The device of  claim 6 , wherein a supply of heating agent restoring fluid is connectable to the processing chamber if the heating agent requires restoration to its nominal properties. 
     
     
         8 . The device of  claim 1 , wherein the shovels of each set of shovels extend radially from a respective surface of a common rotary shaft,
 wherein each shovel, as viewed radially from the rotary shaft, has a curved cross-section so as to present upon rotation of the set of shovels a convex surface to face the primary component(s) to be homogenized,   wherein the shovel at an radially outer region is forwardly flared in a direction of a homogenizing mode of rotation, the outer region thereby having a forward face forming an angle with the rotary forwardly facing convex surface of the remainder of the shovel,   wherein an aerodynamic member extends rearwards from a concave side of the shovel, transversely of a radial direction of the shovel, wherein the aerodynamic member has its widest dimension closest to said concave side, and   wherein a space between said concave side of the shovel and the aerodynamic member yields a sealed cavity.   
     
     
         9 . The device of  claim 1 , wherein a radially extending side edge region of at least some of the shovels is provided with a wing-like side member protruding laterally from said side edge region, and
 wherein the wing-like side member is turned forwardly in the direction of rotation of the shovel in its homogenizing operational mode, so as to form an angle with an edge of a convex side of the shovel and a forwardly flared region of the shovel.   
     
     
         10 . The device of  claim 7 , wherein the heating agent restoring fluid is one of inert gas, vapour, superheated steam and air. 
     
     
         11 . The device of  claim 8 , wherein the aerodynamic member has a drop or wedge shaped configuration. 
     
     
         12 . The device of  claim 8 , wherein a radially extending side edge region of at least some of the shovels is provided with a wing-like side member protruding laterally from said side region, and wherein the wing-like side member is turned forwardly in the direction of rotation of the shovel in its homogenizing operational mode, so as to form an angle with an edge of the convex surface side of the shovel and the forwardly flared region of the shovel.
