Problems solved by technology

Due to the different flow resistances and thus different flow rates in the mixing channels of the hopper, this design facilitates good mixing of the contents of the container; however, said mixing channels are complex to implement
Furthermore, clogging of narrow mixing channels cannot be avoided
In particular, the powders to be mixed are often prone to bridging, blocking any narrow part of the mixing channel

Embodiment Construction

[0022] A mixing silo in Figure 1 is used to store and mix pourable solid particles, especially powders. The mixing silo 1 comprises an upright mixing vessel 2 having a hollow cylindrical wall 3 opening upwards to form a vessel inlet 4 and having a downwardly continuing wall 3 tapered in a tapered shape. Forming the bottom 6 of a container outlet 5 , the mixing container 2 is rotationally symmetrical about a longitudinal center axis 7 .

[0023] In the mixing container 2 at the level of the transition from the wall 3 to the bottom 6 there is a central pipe 8 whose longitudinal axis coincides with the longitudinal center axis 7 of the mixing container 2 . The central tube 8 is mounted in the mixing vessel 2 via four vertical support walls 9 , 10 , 11 , 12 distributed radially with respect to the longitudinal center axis 7 . The support walls 9 , 10 , 11 , 12 are offset from one another by 90° in the circumferential direction about the longitudinal center axis 7 . The support w...

Abstract

The invention relates to a blending bin (1) for powders and other bulky materials, which comprises a tubular blending container (2) having a vertical axle wire. The container has an inlet (4), an external wall (3), an outlet (5) and a bottom (6) towards the outlet (5) becoming thin gradually and passing into the outlet (5). A plurality of blending passages (13 to 17) are arranged between the outlet (5) and the inlet (4), in which, at least two blending passages (13 to 17) have different cross sections at least locally. At least two blending passages with different cross sections of the blending passages (13 to 17) are partially limited by pressure discharge parts (18 to 21) from the support structures of the inside and middle side of the blending container (2). The pressure discharge parts (18 to 21) are different with each other in geometric shape. So that the good blending of the materials in the blending bin (1) is realized, at the same time, the designs of the blending passages (13 to 17) are simple.

Description

technical field [0001] The present invention relates to a mixing silo for powders or other loose and pourable materials, comprising: a tubular mixing container with a longitudinal center axis, the mixing container has an inlet, an outer wall, an outlet and a a bottom that tapers into the outlet; a central support structure within the mixing vessel; a plurality of mixing channels within the mixing vessel between the inlet and the outlet, and wherein at least two of the channels have different minimum cross-sections . Background technique [0002] A mixing silo of the type described is known from document DE 4112884 C2, wherein a feeding hopper is arranged on a central support structure in the mixing container and is divided into a plurality of mixing channels by sheet metal. The cross-sections of the mixing channels differ from each other near their outlet ends. Due to the different flow resistances and thus the different flow rates in the mixing channels of the hopper, thi...
