Abstract

The utility model relates to a plastic extruding polystyrene CO2 foaming device which mainly solves a problem that the commixing effect of the existing plastic extruding polystyrene CO2 foaming device is not ideal, so CO2 can not be better dispersed over polystyrene. The utility model is characterized in that a discharge port (4) of a double-screw rod extruder (3) is connected at a feed port (2) of a single-screw rod extruder (1) in a sealing way, and an assistant feeding port (7) and a foam beater feeding port (8) are arranged on the double-screw rod extruder (3). The plastic extruding polystyrene CO2 foaming device uses the double-screw rod extruder (3) to mix, and then, uses the single-screw rod extruder (1) to transport and cool. The plastic extruding polystyrene CO2 foaming device has good commixing effect and transporting and cooling performance.

Description

A kind of extruded polystyrene CO 2Foam device
Technical field:
The utility model relates to a kind of foamed polystyrene device, especially extruded polystyrene CO 2Foam device.
Background technology:
At present, the foamed polystyrene device mainly is to utilize single screw extrusion machine to carry out the blend foaming, and this device can only be used for the freon foaming.According to the promise of the Chinese government to the world, freon will be cut down and use to not using fully, therefore adopts the CO of compliance with environmental protection requirements in foamed polystyrene technology 2As blowing agent, CO 2Blowing agent extracts from atmosphere, CO on the market 2Price be 600 yuan/ton, the price of freon is 10000 yuan/ton.So CO 2Novel polyphenyl ethylene production pattern as blowing agent not only has the remarkable environmental effect, but also has good economic expection.But existing single screw extrusion machine blend effect is undesirable, can't make CO 2Better be dispersed in the polystyrene, be difficult to satisfy CO 2Technological requirement requirement as blowing agent.
The utility model content:
Undesirable in order to overcome existing extruded polystyrene foam device blend effect, can't make CO 2Better be dispersed in the deficiency in the polystyrene, the utility model provides a kind of extruded polystyrene CO 2Foam device, this extruded polystyrene CO 2Foam device is adopted double screw extruder and is mixed, and carries and cooling with single screw extrusion machine then, has blend effect preferably and conveying and cooling performance.
The technical solution of the utility model is: this extruded polystyrene CO 2Comprise single screw extrusion machine, the be tightly connected discharging opening of double screw extruder of the charging aperture place of single screw extrusion machine; Double screw extruder is provided with that auxiliary agent is dosed mouthful and blowing agent is dosed mouth.
The pitch of the twin-screw in the described double screw extruder is decreasing worm-pitch, and its input is that coarse pitch and output are fine pitch.
Described screw rod is a plurality ofly to be connected in turn and to link to each other with power set.
The utlity model has following beneficial effect: owing to take double screw extruder in the such scheme to be sealedly connected on the charging aperture place of single screw extrusion machine, make that material can be fully before entering single screw extrusion machine and CO 2The effective blend of blowing agent and auxiliary agent can make CO 2Better be dispersed in the polystyrene of fusion, improve CO with this 2Solubility in polystyrene has also improved Products Quality.The material that mixes is conveyed in the mould expeditiously simultaneously by single screw extrusion machine, also can the secondary blend in this course of conveying with, it is undesirable to have solved in the background technology extruded polystyrene foam device blend effect effectively, can't make CO 2Better be dispersed in the problem in the polystyrene.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations of Fig. 1 double screw extruder 3;
Accompanying drawing 3 is enlarged drawings of Fig. 2 twin-screw 5.
1-single screw extrusion machine among the figure, the 2-charging aperture, the 3-double screw extruder, the 4-discharging opening, the 5-twin-screw, the 6-power set, the 7-auxiliary agent is dosed mouth, and the 8-blowing agent is dosed mouth.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, this extruded polystyrene CO 2Foam device comprises single screw extrusion machine 1, the be tightly connected discharging opening 4 of double screw extruder 3 of charging aperture 2 places of single screw extrusion machine 1; Double screw extruder 3 be provided with auxiliary agent dose mouthfuls 7 and blowing agent dose mouthfuls 8.Owing to adopt such scheme, material can be fully before entering single screw extrusion machine 1 and CO 2The effective blend of blowing agent and auxiliary agent can make CO 2Better be dispersed in the polystyrene of fusion, improve CO with this 2Solubility in polystyrene.The material that mixes is conveyed in the mould expeditiously simultaneously by single screw extrusion machine 1, also can the secondary blend in this course of conveying with, it is undesirable to have solved in the background technology extruded polystyrene foam device blend effect effectively, can't make CO 2Better be dispersed in the problem in the polystyrene.
By shown in Figure 3, the pitch of the twin-screw 5 in the described double screw extruder 3 is decreasing worm-pitch, and its input is that coarse pitch and output are fine pitch.
By shown in Figure 2, described twin-screw 5 is connected in turn and links to each other with power set 6 for a plurality of, and wherein the order of screwing element can be according to the different independent assortments of material.
