Abstract

PROBLEM TO BE SOLVED: To remove troubles in which the inside diameter surface of the inserted barrel of a screw does not agree with that of a screen by a method in which the replacement of a dewatering barrel can be done by the inexpensive replacement of a constituting member, the barrel is assembled by easy work, and the positioning of the screen is unnecessary in the assembly. SOLUTION: In a dewatering barrel 20 which is the component member of the barrel of a twin-screw extruder, has a barrel in which divided barrels are connected integrally, supplies a polymer of a high water content, and extrude it as a polymer of low water content, a stepping part for positioning a screen 27 which filters water, etc., to discharge them outside a machine body is formed in the drain opening 26 of a barrel main body 21, and two plates which are fixed by a bolt 25 beyond the barrel main body 21 through a spacer 24 to hold a dewatering barrel main body 20 from both end parts in the shaft direction of the barrel main body 21 are provided. When the barrel is replaced, only the component member is replaced, and since a stepping part is formed for positioniong to set the screen, troubles in which the inside diameter of the barrel into which the screw is inserted does not agree with that of the screen can be removed.

いる。2. Description of the Related Art A method of extruding a polymer containing a large amount of water by a twin-screw extruder having a barrel formed by integrally connecting a plurality of divided barrels as shown in FIGS. 3 and 4 is well known. To explain the method, 1 is 2
A feed barrel 3 having a supply port 2 by a screw extruder and a discharge port 4 downstream of the feed barrel 3 for discharging water from the high water content polymer supplied from the supply port 2 are closed and strained from the water content polymer. A dewatering barrel 5 provided with a screen 14 for discharging the dewatered water and the like to the outside of the machine body, and a vent port 6 downstream of the dewatering barrel 5 for removing water, volatile matter and the like which could not be completely dewatered by the dewatering barrel 5. In the barrel 9 in which the provided vent barrel 7 and a plurality of standard barrels 8 are integrally connected, a screw lead is large near the supply port 2 and is sent from the upstream between the discharge port 4 and the vent port 6. A two-shaft interlocking shaft provided with a kneading desk 10 for giving resistance to the material and squeezing out moisture and the like from the material and a screw element 11 of a reverse lead for making the ventilation more effective. Cru 12 is inserted rotatably.

While being melted, it is sent forward (to the left in the figure) and the screen 1 of the dewatering barrel 5
While being dehydrated through the drain port 4, water and the like that have not been completely dehydrated by the dehydration barrel 5 are removed from the vent port 6 and finally extruded from the discharge port 13 as a low water content polymer.

喰違いができ、不都合であった。However, the dewatering barrel 5 is very expensive because if the outlet 4 and the screen 14 are rusted or corroded by moisture or the like, the dewatering barrel 5 has to be replaced. Not only was it difficult, but the work was troublesome. In the case of the screen 14, there is no positioning for mounting the screen 14 at the outlet 4 of the dewatering barrel 5, and the barrel 5 into which the screw is inserted is not used.
There was a difference in the joint (“a” portion) between the inner diameter surface and the inner diameter surface of the screen 14, which was inconvenient.

It is an object of the present invention to provide a dewatering barrel for eliminating the inconvenience that the inner diameter of the barrel in which the screw is inserted and the inner diameter of the screen do not cross each other.
