Hochst, Germany,
assignor to I. G. Farbenindustrie Aktiengesellschaft, Frankfort-on-the- Main, Germany Application Jul as, 1937, Serial No. 155,346
4 Claims.
The present invention relates to a kneading pump.
In the co-pending U. S. application Serial No. 112,602 filed November 24, 1936, now Patent No. 2,115,096, dated April 26, 1938, in the name of Franz Burghauser there is described a kneading pump consisting of a casing and several right handed and left handed worms (at least one right handed worm and one left handed worm) arranged in the casing and having closely intermeshingthreads, the threads of the worms being so formed-that the width of the space between adjacent flanks of each thread progressively varies from one end to theother, the main Worm to which the material to be kneaded is supplied by an inlet in the casing, having a thread which provides a decreasing passage from the inlet to the outlet side, the secondary worm which closely intermeshes with the main worm having a thread which provides a passage increasing correspondingly towards the outlet. of the casing. In this arrangement the casing may be totally closed around the said main worm at the outlet side and around the said secondary worm near the inlet side. The worms may be connected with means for moving them against each other in the axial position.
On further investigations I have found that it may be advantageous for many purposes to construct the casing of the pump so that at the outlet side a hollow space is formed around the.
axis of the main worm. This hollow space is suitably provided with a boring which is closed by a removable plug.
In the hollow space foreign bodies which enter into the pump together with the material are collected. The foreign bodiescannot then, after being more or less comminuted leave the pump together with the material or the pump be forced to stop, with the possible consequent endangering of other devicees connected with the pump;
Figures 1 and 2 of the accompanying drawing diagrammatically illustrate a pump constructed in this manner.
Figure 1 is a longitudinal section, and
Figure 2 is a part section on the line E- -F of Figure The casing of the pump c is constructed so that on the pressure side (outlet side) a hollow space i is produced at the end of the thread of the main warm (1. .In the case of the secondary worm b the hollow space which would otherwise be formed is filled up by .an adjusting ring In I mountedon the secondary worm so that the material cannot leave the hollow space i and enter Germany July 30, 1936 into the passage of the secondary worm b. Furthermore the hollow space i is provided with a boring I which is closed by a plug m.
When the dimensions of the crevices between the flanks s-s are adjusted to the smallest value 5 any solid foreign body which enters into the pump together with the material to be kneaded is caused to slide in the passage of the worm a to the outlet side and is caused'to settle in the hollow space i. The foreign bodies which may have m collected m'ay be eliminated from time to time by removing the plug m.
I claim:
