して押出される。 Traditionally, hot air drying equipment was used in the drying process during the production of resins, synthetic rubber, etc., but because it consumes a large amount of energy,
Instead of this, a dehydration kneading device as shown in FIG. 1 is also used. The cylinder 1 consists of a supply part 2 whose diameter is reduced in a tapered shape, and a compression part 3 of equal diameter extending from the tip of the supply part 2. Correspondingly, the screw 4 also has a supply part 5 and a compression part. It consists of 6. The supply section 2 of the cylinder 1 is provided with a hopper opening 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 hopper port 7 is sent from the supply section 2 of the cylinder 1 to the compression section 3 by the screw 4, at which 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.

を生ずる。 However, in such conventional dehydration kneading equipment, materials with low elasticity (for example, ABS wood)
In this case, the compression squeezing effect does not work sufficiently,
Since the material containing moisture is kneaded, there is a problem in that the material is insufficiently melted and surging occurs. In addition, the slit 8 for discharging water and steam was easily clogged, and when it was clogged, the water and steam would flow back into the hopper opening 7, making it difficult to charge materials smoothly. If the gap between the slits 8 is increased to prevent clogging, the problem arises that the raw material spills through the gap and the recovery rate decreases.

The purpose of the present invention is to provide a dehydration and kneading device that can be used without causing problems such as backflow of raw materials.

円滑に混練・脱水を行なうことができる。 The raw material inlet 24 is located in the hopper 25 of the compactor 23.
The raw materials inputted from Compactor Skrill 26
is forcibly fed into the supply section 12 of the cylinder 11, and is sent to the kneading section 13 of the cylinder 11 by the supply section 17 of the screw 16. Skrillyu 1
Compression and shearing action is applied to the raw material by the forward thread 18a of the kneading section 18 of No. 6, water in the raw material is squeezed out, and the raw material starts to melt. However, the molten raw material is pushed back by the reverse threaded part 18b following the normal threaded part 18a, and the raw material is pushed back into the cylinder 11.
Temporarily stays in the kneading section 13. 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 to the discharge part 15 of the cylinder 11 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 portion of the water receives heat during melting flows back to the upstream side (left side in the figure) of the supply section 12 of the cylinder 11 where the internal pressure is low. 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 the screw 16
Since the supply section 17 has a sufficient length, the raw material is sent to the downstream side against the above force. 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 will be sent downstream without being disturbed by water and steam. By the way, when the cylinder 11 is filled with resin and the steam pressure begins to rise, such as when trying to increase the capacity by increasing the rotational speed of the screw 16, the pressure sensor 30 and the electromagnetic valve 31 act to The pressure is controlled so that it does not exceed a certain value. That is, when the pressure detected by the pressure sensor 30 reaches, for example, 0.5 kg/cm 2 , the electromagnetic valve 31 is opened to release the pressure, and the pressure near the pressure sensor 30 is always maintained.
Keep it below 0.5Kg/ cm2 . This prevents the backflow of the resin and allows smooth kneading and dehydration even during high capacity operation.

No. (Japanese Unexamined Patent Publication No. 58-45726) discloses a dehydration kneading device that does not have a pressure sensor or an electromagnetic valve. There were cases in which the pressure increased and resin backflowed, making smooth operation impossible. The dehydration kneading device of the invention according to the present application is provided with the pressure sensor and the electromagnetic valve as described above to prevent the pressure in the cylinder from increasing, and to always enable smooth operation even during high-capacity operation. Therefore, the dehydration and kneading apparatus of the present invention has further improved performance than the dehydration and kneading apparatus disclosed in Japanese Patent Application No. 144680/1982 (Japanese Patent Application Laid-Open No. 45726/1987).

A pressure sensor capable of detecting the pressure inside the cylinder of this part and an electromagnetic valve capable of discharging the steam inside the cylinder of this part are installed between the provided position and the kneading part of the cylinder, and the electromagnetic valve has a pressure sensor that can detect the pressure in the cylinder of this part and the kneading part of the cylinder. The cylinder is opened when the cylinder pressure is detected, and is closed otherwise, so the pressure inside the cylinder does not become higher than necessary, and water and steam flow back upstream and the raw material is It is smoothly transferred to the downstream side and a sufficient dewatering effect can be obtained. Therefore, even raw materials lacking in elasticity can be reliably dehydrated and sufficiently melted. Also, since a compactor is provided, raw materials will not flow back into the hopper opening. 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.
