Embodiment Construction

[0026] according to figure 1 , the multi-shaft extruder comprises a drive device 1 with twelve pinion shafts 2 arranged along a circle and connected via an adapter 3 to a worm shaft 4 of a processing part 15 .

[0027] according to figure 2 , the twelve shafts 4 of the processing unit 5 are arranged in an axis-parallel manner along the pitch circle 7 in the annular space 8 between the outer housing 9 and the inner core or inner housing 10 and rotate in the same direction. The worm shaft 4 is non-rotatably connected to the interlocking conveying screws 11, 12, 13 and other elements. To this end, the conveying screws 11, 12, 13 and other elements are connected via spline teeth 14 (cf. image 3 ) is pushed onto axis 4.

[0028] according to figure 2 , The outer casing 9 is provided with an axis-parallel concave arc segment 15 inside. Likewise, the inner housing 10 has an axis-parallel concave arc segment 16 . The arc segments 15 , 16 receive the corresponding shaft 4 and ...

Abstract

A multi-shaft extruder has at least six worm shafts (4) between an exterior housing (9) and an interior housing (10), wherein the worm shafts are disposed in a circle (7). The drive (1) of the multi-shaft extruder has two pinion shafts (2), which are partitioned into groups of identical design and disposed on a circle, the shafts being radially driven from the inside and the outside at equal forces and in the same direction, and are disposed diametrically opposed from each other. The shafts are coaxially connected to the worm shafts (4) of the process part (5) via couplings (3), wherein the worm shafts (4) have a feed length (L) of at least six Do, and a Do / Di ratio of 1.5 to 1.93, wherein Do represents the outside diameter and Di represents the inside diameter of the feed screws (11, 12,13), and the torque density of the extruder is at least 50 Nm / cm<3>.

Description

technical field [0001] The invention relates to an extruder according to the preamble of claim 1 for the continuous preparation of substances, said extruder comprising a drive, and connected securely to the Processing part of the drive unit. Background technique [0002] In many cases, the mechanical and thermal equipment of the substance with an extruder is carried out in several stages through a combination of conveying sections distributed over the processing length for mixing, melting, wetting, dispersing, degassing, reacting, etc. In this case, different substances, such as granules, fibers, powders, etc., which are at least partly viscous and can be plastically deformed in different forms and concentrations, are supplied, processed and extruded in a plastic, temperature-controlled process to form Shaped items such as profiles or particles that form unshaped. This requires a lot of energy for heating and plasticizing if the article is fed to the extruder at room tempe...
