  • the materials to be mixed or blended contain a fluid material or high viscosity, a powder or a solid material
  • the flowing stream is often caused to hold up due to the viscosity resistance generated at the corner among the rear portions of the rectangular members and the inner wall of the conduit 1.

  • Liquid stream to be mixed or blended is divided into upper and lower smaller partial streams by the divider plate of the first mixing stage at the up-stream side, and thereafter, each partial stream is again divided into two partial streams by the divider plate of the mixing stage 7, therefore, the initial liquid stream is resultantly into four partial streams.
  • Such division occurs at the divider plate of the mixing stage 8 into l6 partial streams and at the divider plate of the mixing stage 9 into thirty two partial streams and so forth, thereby intimately mixing the materials.
  • the stream divided by each divider plate is guided by the deflector plates to thereby trace a vertical and horizontal zigzag course, and is repeatedly divided and combined, thereby attaining a prominant mixing effect. Further, since the liquid stream takes a zigzag course and passes through, flows over and is compressed by the deflector plates 2, 3 and divider plates 4, 5 with an increased velocity, the mixing effect more prominantly increases.
  • quasi-conical bodies 11 are disposed at the corners between the deflector plates 2, 3 and the inner wall of the conduit 1 for the purpose of preventing the hold-up of the flowing stream and to thereby pass the substances smoothly through the conduit 1.
  • the quasi-conical bodies constitute dead spaces" in the conduit 1, however, the occupation ratio of the quasi-conical bodies in the conduit 1 may be as low as 2 percent. Therefore, the disposition of the quasi-conical bodies is considered to be highly effective in uniformly mixing and dispersing the substances.

  • A), B), and C These prior art patents are indicated hereinafter as (A), (B), and (C). These have been developed in the U.S.A. and are similar to the present invention in that they also are not equipped with any mechanical driving means or rotary agitator.
  • the device of the prior art patent (A) comprises a circular conduit, and unit elements each comprising spiral blades jointed normal to each other. Therefore, the device (A) is completely different in its construction from that of the present invention. Further, since, in the prior art patent (A), the functions of the divider and deflector plates are not distinguished, the action and effect obtained by such distinct classification as in the present invention cannot be obtained.
  • the stream passes through all of the spaces in the conduit 1.
  • the apparatus of the prior art (B) or (C) has much dead space in its conduit due to the blocks disposed therein.
  • the dead spaces occupy a volume larger than the effectively usable space therein, and therefore, it is not considered to be particularly economical either from the manufacturing cost standpoint or from the operation cost standpoint. Accordingly, it should be noted that the present invention is distinguishable from the prior art in that there is substantially no dead space in the conduit.

  • the obliquely lined portions indicate the stream of a material to be mixed.
  • FIG. 12 shows a progressive modification of the sectional configuration of flowing streams. It is understood from FIGS. 12 and 15 that the flowing streams are complicatedly modified due to a converting action thereon accompanied by the displacement of streams indicated in c and d of FIG. 12, and modification of the flowing passage shown in 6" B.
  • a fin member may be disposed in the portion indicated by FIG. 16 so that the stream passes more smoothly therethrough.
  • the stream flows over the fin member and passes through a narrow passage, and it is contracted smoothly without any appreciable pressure drop.
  • Such a member is not disclosed in the prior art patents (B) and (C).
  • the deflector plates of the mixing element of this invention are very effective in preventing the stream from shortly passing through the conduit, since they always face the flowing stream and have wall faces to guide the same. Further, the flowing direction of the stream is smoothly changed at right angles by the passage shown in F G or G F of FIG. 15, thereby increasing the velocity of the stream in a direction other than longitudinal axis to prevent the short pass of the stream. Therefore, the present invention is distinguishable from the prior art in view of the above mentioned effect.
