この発明は、鷹練度合の調節が随意にできる連続泥練装
置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous mud kneading device in which the degree of kneading can be adjusted at will.
従釆の連続混練装置は、材料を連続的に安定して搬送す

である。In such a screw-type continuous crosstalk device, the number of revolutions of the screw is naturally determined in order to determine the throughput. Therefore, it has been difficult to adjust the degree of kneading by adjusting the rotation speed of the screw. Therefore, there was a problem in that when it became necessary to change the degree of kneading, the screw (or mixing blade) had to be replaced. The present invention has been made in view of the above circumstances, and is a continuous kneading device in which a plurality of screws are provided in parallel in a cylinder barrel in a state of engagement, and a continuous kneading device is provided in which a plurality of screws are engaged with each other and are provided in parallel in a cylinder barrel. The axis of the screw is set thinner than the axis of other screws,
The gist of the present invention is that at least the rotational speed of the other screws mentioned above can be changed as appropriate.
すなわち、このように、複数本のスクリューのうちの適

明を実施例にもとづいて説明する。Therefore, by keeping the rotational speed of the thin-shafted screw constant, the throughput can be kept constant. Furthermore, the degree of kneading can be easily adjusted during operation by appropriately changing the rotational speed of the other screws. Next, the present invention will be explained based on examples.

。In these figures, a central screw 2 is coaxially provided in the center of the cylinder barrel 1 of the Renzu kneading device,
Both end screws 3 (rotating in the same direction as the center screw 2) that mesh with the center screw 2 are provided above and below. The diameter of the shaft 4 of the central screw 2 is smaller than the diameter of the shaft 5 of the screws 3 at both ends,
Most of the kneading material (not shown) can be transported. Further, the screws 3 at both ends mainly have a material kneading function, and the number of rotations thereof can be changed arbitrarily. Note that 6 is a flight of the center screw 2, and 7 is a flight of both end screws 3. The cylinder barrel is also kept at a high temperature by steam or an electric heater (not shown). In a continuous mixing device having such a structure, the thickened material supplied to one end (not shown) of the device is conveyed to the outlet (not shown) at the other end by the rotation of the center screw 2 and both end screws 3. At that time, the material is melted and kneaded by the heat from the cylinder barrel, which is heated to a high temperature.

のである。This continuous crosstalk device has a shaft 4 of the central screw 2.
is smaller than the diameter of the shaft 5 of the screw 3 at both ends, so the material flow path is wide at the center screw and narrow at the screws at both ends. therefore,
Most of the material is transported by the central screw 2. Therefore, by keeping the rotational speed of the central screw 2 constant, the amount of material conveyed, that is, the amount of material to be processed can be kept constant. Further, the degree of straining of the material can be adjusted by changing the rotational speed of the screws 3 at both ends, which mainly have a kneading function. In other words, this Renzuki kneading apparatus maintains the rotation speed of the central screw 2 constant to stably maintain a predetermined throughput, and also changes the rotation speed of the screws 3 at both ends to adjust the degree of kneading of the material. It can be changed.
なお、この発明は、上言己のような３鞠式連続混糠装置

である。As described above, the continuous kneading device of the present invention is a continuous kneading device in which a plurality of screws are provided in parallel in a cylinder barrel in a state of engagement, and an appropriate one of the plurality of screws is The shaft of the screw is set thinner than the shafts of the other screws, and at least the rotational speed of the other screws mentioned above can be changed as appropriate, so the degree of cross-contamination of materials can be controlled while keeping the throughput constant. This is a revolutionary feature that can be easily changed.
