Abstract
The invention discloses a serial type extruder. In the invention, the nose of a first extruder is in side sealing connection with a second section barrel of a second extruder; and the nose of the second extruder is in side sealing connection with a second section barrel of a third extruder. The serial type extruder is characterized in that multiple stages of extruders are adopted, which can greatly improve the retention time of materials; a connecting section is provided with a heating and cooling device which can be used for heating or cooling the materials; and the extruders can be vacuumized to remove residual micromolecules in the materials.
Description
Technical field
The present invention relates to a kind of extruder, particularly a kind of tandem extruder.
Background technology
With extruder to polymer react extrude processing can serialization production, and equipment investment is little, output height, thereby use very extensive.But reaction is extruded and is required material fully to mix, the time of staying is long, this just requires screw slenderness ratio long as much as possible, but no matter be single screw rod or twin-screw and multiscrew at present, draw ratio is all less, is difficult to reach the very long time of staying, therefore reaction conversion ratio is lower, monomer residue is more, can not prepare the higher response type polymer of ask for something, has limited the range of application that reaction is extruded.At present, a kind of method that addresses this problem is the screw extruder of preparation superelevation draw ratio, but screw strength, screw rod and barrel cooperate and the solution difficulty of the technical problem such as be in transmission connection of screw rod very big, have only the external producer of minority to produce, investment is high, apparatus expensive, maintaining is also extremely complicated, can not satisfy large-scale popularization and application.
Chinese patent 200920043494.6 discloses a kind of tandem single screw extrusion machine, its machine barrel is made up of the first rank machine barrel and the second rank machine barrel, the first rank extrusion screw rod is installed in the first rank machine barrel, basis, second rank screw rod is installed in the second rank machine barrel, the delivery outlet of the first rank machine barrel links to each other by the input port of pipeline with the second rank machine barrel, and charging aperture is positioned on the first rank machine barrel.Its weak point is that pipeline is comparatively tortuous, makes to change extremely complexity of screw rod, is not suitable for the production multiple product.
Summary of the invention
Mother of the present invention is to provide a kind of tandem extruder, improves residence time of material, is beneficial to little molecule devolatilization, convenient other component that adds in reaction.
Tandem extruder of the present invention, the head of first extruder carry out lateral seal with the second joint machine barrel of second extruder and are connected, and the head of second extruder carries out lateral seal with the second joint machine barrel of the 3rd extruder and is connected.
In addition, the draw ratio of first extruder and second extruder is the screw diameter of the screw diameter of the 40/1~56/1, the 3rd extruder greater than first extruder and second extruder; The second joint machine barrel of the head of first extruder and second extruder carries out lateral seal and is connected to the tubular metal sealing and is connected linkage section band heating-cooling device; The base of first extruder, second extruder or the 3rd extruder is established pulley and slide rail; First extruder is provided with charging aperture, and the charging aperture of second extruder links to each other with the discharging opening of first extruder, and the charging aperture of the 3rd extruder links to each other with the discharging opening of second extruder; Contain at least two vacuum ports on the 3rd extruding machine barrel.
The invention has the advantages that:
1. adopt multistage extruder, can improve the time of staying of material greatly;
2. linkage section band heating-cooling device can carry out heats cold or but operation to adding material;
3. can vacuumize extruder, thereby can remove little molecule residual in the material.

Description of drawings
Fig. 1 is the structural representation of extruder of the present invention.
The specific embodiment
The specific embodiment with the tandem extrusion equipment is extruded in reaction involved in the present invention, is described in detail as follows with reference to accompanying drawing:
Combined type extrusion equipment involved in the present invention mainly is composed in series successively by three parallel dual-screw extruding machines, the head 5 of first extruder 1 seals with the charge door 4 of second extruder 3 and is connected, the head 8 of second extruder 3 is connected with the charge door 7 of the 3rd extruder 6, is connected to the tubular metal sealing and connects.First extruder 1 and second extruder 3 are selected the extruder of threaded diameter model of the same race for use, and draw ratio is 40/1~56/1; The 3rd extruder 6 selects for use screw diameter greater than preceding two screw diameter.
The base of first extruder 1, second extruder 3 or the 3rd extruder 6 is established pulley and slide rail; Contain at least two vacuum ports 9 on the 3rd extruder 6 barrels.
After extruder involved in the present invention reaches needed temperature, at first open the 3rd extruder 6 to the rotating speed that needs, open second extruder 3 again, open first extruder 1 at last, materials mixed is added charge door 2, material reacts after the 1 abundant plasticizing of first extruder mixes, fed second extruder 3 by linkage section by screw compulsory, material is proceeded sufficient reaction at second extruder 3, fed the 3rd extruder 6 by linkage section by screw compulsory again, the screw diameter of the 3rd extruder 6 is big, the barrel internal pressure reduces rapidly, and under the continuous stirring of screw rod, little molecule is overflowed fast, the device that is evacuated at vacuum port 9 is got rid of, and material is extruded extruding dies after reaction finishes.
