あつた。Conventionally, hot air drying equipment was used in the drying process during the production of resins, synthetic rubber, etc., but since it consumes a large amount of energy, dehydration kneading equipment as shown in Figure 1 has been used instead. equipment is also used. cylinder 1
consists of a supply section 2 whose diameter is reduced in a tapered shape, and a compression section 3 of equal diameter extending from the tip of the supply section 2. Correspondingly, the screw 4 also consists of a supply section 5 and a compression section 6. It is completed. The supply section 2 of the cylinder 1 is provided with a hot spring 7 and a slit 8, and a die 9 is provided at the tip of the compression section 3. The raw material inputted from the hotsparo 7 is sent from the supply section 2 of the cylinder 1 to the compression section 3 by the screw 4, and at this time the raw material is compressed and water is squeezed out. The raw material from which water has been squeezed out is melted in the compression section 3 and extruded through a die 9. However, in such conventional dehydration kneading equipment, materials with low elasticity (for example, A
In the case of BS resin), the compressed part ejecting effect does not work sufficiently and the material containing moisture is kneaded, resulting in insufficient melting of the material and the occurrence of surge fern. .

とを目的としている。In addition, the slit 8 for discharging water and steam was easily clogged, and when it was clogged, the water and steam flowed back into the hopper 7, making it difficult to smoothly charge the material. If the gap between the slits 8 is increased to prevent clogging, the problem arises that the raw material spills through the gap 7 and the recovery rate decreases. The present invention solves the above-mentioned problems in conventional dehydration kneading equipment, makes it possible to sufficiently squeeze out water even from raw materials lacking in elasticity, and smoothly discharges the squeezed out water. The purpose is to obtain a dehydration kneading device that can perform

A compactor 23 is provided in the downstream part of the supply section 12 of the cylinder 11 (the right part in the figure). In this specification, "upstream side" and "downstream side" are based on the flow of raw materials through the screw 16 (from left to right in FIG. 2). The compactor 23 has a hopper 25 having a raw material inlet 24, a compactor refiner 26, and a motor 27 for driving the compactor refiner 26. The diameter of the constricted portion 14 of the cylinder 11 is reduced to a conical shape. The discharge portion 15 of the cylinder 11 has a discharge hole 28 opened downward and an exhaust hole 29 opened upward. Note that the cylinder 11 is inclined so that water flows upstream.

十分な脱水効果が得られる。Skrill 1. Compression and shearing action is applied to the raw material by the normally threaded part 18a of the kneading section 18 '6, water in the raw material is squeezed out, and the raw material starts to melt. However, the molten raw material is transferred to the reverse threaded portion 1 following the normal threaded portion 18a.
8b and kneading section 1 of cylinder 1.11.
Temporarily stays at 3. The temporarily retained raw material is then sent from the supply section 12 of the cylinder 11 and is pushed by the melted raw material, and is compressed through the gap between the constriction section 14 of the cylinder 11 and the constriction section 19 of the screw 16. After receiving it, it is pushed out by the discharge part 15 of the cylinder 11q and falls through the discharge hole 28. On the other hand, the water squeezed out from the raw material and the steam generated when a part of the water is heated during melting flow back to the upstream side (left side in the figure) of the supply section 12 of the cylinder 1, which has a low internal pressure. In this case, water and steam cannot flow back into the compactor 23. This is because the raw material is forcibly fed by the compactor screw 26. Water and steam therefore flow back further upstream of the feed section 12 of the cylinder 11. Due to this backflow, an upstream force also acts on the raw material in the supply section 12 of the cylinder 11, but since the supply section 17 of the screw 16 has a sufficient length, it can resist this force. The raw material is sent downstream. Therefore, water and steam are sent upstream, and raw materials are sent downstream. The water and steam sent to the rear are discharged from the dehydration port 22 and the deaeration port 21, respectively. Therefore, the raw material is sent downstream without being disturbed by water and steam. In the above embodiments, the screw was a single shaft, but it is clear that a multi-shaft screw may also be used. Alternatively, the exhaust port 21 may be set to negative pressure using a pump or the like to forcibly extract the steam. As explained above, according to the present invention, the compactor forcibly supplies raw materials to the supply section of the cylinder of the kneader, the cylinder of which is arranged obliquely so that the raw materials are transferred diagonally upward. A dehydration port and a deaeration port are provided for discharging water and steam (other liquids and gases may also be used), respectively, at a position upstream of the flow of raw material due to screw feed from the position where the compactor is installed in the cylinder supply section. Since the opening (including cases where the dehydration port and the deaeration port are the same opening) is provided, water and steam flow back upstream, and raw materials are smoothly transferred downstream.
A sufficient dehydration effect can be obtained.

Furthermore, since slits for discharging water and steam are not required, problems such as clogging of the slits do not occur. Further, since the kneading part of the screw is provided with a reverse threaded part, sufficient dehydration and kneading can be carried out.
