Problems solved by technology

[0005] In the production of traditional equipment, there are the following deficiencies: when the raw materials of the extruded polystyrene foam board are heated and mixed and come out of the No. The original temperature in the screw host is unbalanced, the raw material near the center of the host is hotter, and the temperature near the wall of the host barrel is lower, which is not conducive to the remaining process of producing plates

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 Shown: a static exchanger for the production of extruded polystyrene foam boards, including a protective cover 1 and a rectifying grid 2, the static exchanger is installed in the No. 2 single-screw main screw and mold of the extruded polystyrene foam board production line Between them, the inlet end of the static exchanger is connected to the No. 2 single-screw main engine, and the outlet end of the static exchanger is connected to the mould. The rectifying grids 1 are arranged in the protective cover 2, and the rectifying grids 1 are arranged in a spiral shape. Disturbing rods are arranged inside the rectifying grid 1 to better change the flow direction of raw materials.

[0013] It should be pointed out that those skilled in the art can make some improvements and modifications without departing from the principle of t...

Abstract

The invention discloses a static exchanger for production of extruded polystyrene foam plates. The static exchanger comprises a protection cover and damping screens, and is mounted between a single-screw extruder I and a mould of an extruded polystyrene foam plate production line, wherein a single-screw extruder II is connected to the inlet end of the static exchanger; the mould is connected to the outlet end of the static exchanger; the damping screens are spirally arranged in the protection cover. According to the static exchanger, due to the arrangement of the damping screen, the flowing direction of raw materials is changed and the speed of the raw materials passing through the static exchanger is slowed down from a high-speed rotation state; moreover, the raw materials are cooled, so that other processes on the extruded polystyrene foam plate production line can be conveniently carried out.

Description

technical field [0001] The invention relates to an extruded board manufacturing equipment, in particular to a static exchanger for producing extruded polystyrene foam boards. Background technique [0002] Extruded polystyrene foam board, also known as XPS extruded board, is a material that is continuously extruded and foamed by a special process. structure, so it has the characteristics of high compression resistance, light weight, non-water absorption, airtight wear resistance, and non-degradation. Compared with EPS polystyrene foam board, its strength, heat preservation, and water vapor penetration resistance have been greatly improved. It is especially suitable for heat insulation, heat preservation, and moisture-proof treatment of buildings. It is one of the high-quality and cheap construction materials in today's construction industry. [0003] XPS extruded board has the characteristics of high thermal resistance, low linearity, and low expansion ratio. The closed cell...
