Abstract

The utility model discloses a static exchanger for producing extruded polystyrene foam boards. The static exchanger comprises a protective cover and a damping screen, wherein the static exchanger is arranged between a second single-screw host machine and a mould of a production line of the extruded polystyrene foam boards; the inlet end of the static exchanger is connected with the second single-screw host machine, and the outlet end of the static exchanger is connected with the mould; the damping screen is arranged inside the protective cover; the damping screen is arranged spirally. The flow direction of raw materials is changed through the arrangement of the damping screen of the static exchanger, the raw materials inside the static exchanger is slowed down from a high-speed rotation state, and the raw materials are cooled, and thus the static exchanger is relatively beneficial to the work of other working produces on the production line of the extruded polystyrene foam boards.

Description

A kind of static exchange device of producing extruded polystyrene cystosepiment

Technical field

The utility model relates to a kind of extruded sheet manufacturing equipment, is specifically related to a kind of static exchange device of producing extruded polystyrene cystosepiment.

Background technology

Extruded polystyrene cystosepiment, claim again XPS extruded sheet, be through there being the material of special process continuous extrusion foaming moulding, the dura mater that its surface forms is evenly smooth, the inner foaming of closed pore completely continuous uniform, become alveolate texture, therefore have high resistance to compression, lightweight, does not absorb water, airtight wear-resisting, the characteristic of not degrading, compares its intensity with EPS polystyrol plastic foam plate, insulation, the performances such as anti-water vapor permeable improve a lot, and are particularly suitable for the heat insulation of building, insulation, moistureproof processing is one of inexpensive construction material of current building industry.

XPS extruded sheet has high thermal resistance, low linearity, feature that expansion ratio is low, and the rate of closed hole of its structure has reached more than 99%, forms vacuum layer, avoid Air Flow heat radiation, guarantee the lasting and stable of its heat-insulating property, with respect to the rate of closed hole of polyurathamc 80%, leading superiority is self-evident.Facts have proved the XPS plastic extrusion heated board that 20mm is thick, its heat insulation effect is equivalent to the thick expanded polystyrene (EPS) of 50mm, 120mm solid cement perlite.

XPS extruded sheet follows legacy equipment for these years always to be produced, and its operation principle is as follows: after by material loading workman, the raw material of certain formula being mixed in blender, join in production equipment.Production equipment is that single screw rod adds the two rank of single screw rod composition machine, inject blowing agent simultaneously, through the two rank of single screw rod, machine extruded plastic foam is gone out by mould, through screed and traction, regulate after length and width again, cooling by cooling frame, by saw blade ripsaw limit, saw blade crosscut is cut off, finally with heating wire, carry out length again and accurately cut and then become finished product, packing listing.

In legacy equipment is produced, have the following disadvantages: when the raw material of extruded polystyrene cystosepiment through heating, mix after in No. two single screw hosts at production line out time, raw material is in High Rotation Speed state, and in No. two single screw hosts, original temperature is unbalanced, raw material near center in main frame is warmmer, temperature near main frame barrel is lower, and these are all unfavorable for producing the remaining technique of sheet material.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of static exchange device of producing extruded polystyrene cystosepiment is provided.

The technical solution adopted in the utility model is: a kind of static exchange device of producing extruded polystyrene cystosepiment; comprise protective cover and honeycomb screen; described static exchange device is arranged between No. two single screw hosts and mould of extruded polystyrene cystosepiment production line; the entrance point of static exchange device is connected with No. two single screw hosts; the port of export of static exchange device is connected with mould; described honeycomb screen is arranged in protective cover, and described honeycomb screen is arranged twist.

As preferably, in described honeycomb screen, be provided with disturbing rod, better the flow direction of feed change.

Beneficial effect: the utility model static exchange device honeycomb screen the flow direction that has changed raw material is set; also just changed the High Rotation Speed state of the raw material of process in static exchange device; and by the setting of honeycomb screen; the raw material of protective cover is mixed again; make the raw material of original zones of different different temperatures realize equalized temperature, thereby be more conducive to the work of other operations on extruded polystyrene cystosepiment production line.

Accompanying drawing explanation

Fig. 1 is internal structure schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As shown in Figure 1: a kind of static exchange device of producing extruded polystyrene cystosepiment; comprise protective cover 1 and honeycomb screen 2; described static exchange device is arranged between No. two single screw hosts and mould of extruded polystyrene cystosepiment production line; the entrance point of static exchange device is connected with No. two single screw hosts; the port of export of static exchange device is connected with mould; described honeycomb screen 2 is arranged in protective cover 1, and described honeycomb screen 2 is arranged twist.In described honeycomb screen 2, be provided with disturbing rod, better the flow direction of feed change.

It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.In the present embodiment not clear and definite each part all available prior art realized.
