On exhaust outlet on described flash collection container, the filter with some through holes is installed, the through hole of this filter is wanted to stop powder to fly out; Further, described filter is selected industrial conventional socks formula filter, and this socks formula filter is to comprise the screen pack that some layers have tiny through hole.
Described tube connector is that open at two ends, adopts the stainless steel material of resistance to chemical attack to make, connecting extruder feeding machine and extruder feed opening, and its cross section is rounded or square.
The present invention has charging aperture and flash mouth on the sidewall of tube connector, and the lower limb of flash mouth is higher than the top edge of charging aperture, and at flash mouth, flash pipe is set, when the material level of the mixed material overflowing is during higher than flash pipe import lower edge, this device reclaims flash by flash collection container through flash pipe automatically, and by the socks formula filter on flash collection container, dusty gas is carried out to filtering emission, thereby charging is unimpeded in assurance production process, and reduce environmental pollution and the wasting of resources.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the flash retracting device for extruder feed opening of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, take and be applied to double screw extruder and embodiment of the present invention elaborated as example.
As shown in Figure 1, be the structural representation of the flash retracting device for extruder feed opening of the present invention, described flash retracting device comprises:
Be arranged on the tube connector 1 between extruder and feeding machine, the sidewall of this tube connector 1 has charging aperture 11 and flash mouth 12, and the lower limb of flash mouth 12 is higher than the top edge of charging aperture 11, and in normal productive process, material just can not overflow by flash mouth 12 like this; Preferably, the lower limb of flash mouth 12 is higher than at least 1.5 centimetres of the top edges of charging aperture 11; The lower end of described tube connector 1 is connected with the feed opening on extruder top, and the charging aperture 11 of tube connector 1 sidewall is connected by pipeline with feeding machine;
Be inclined at the flash pipe 2 of the flash mouth 12 of tube connector 1 sidewall, angle [alpha] between this flash pipe 2 and tube connector 1 is according to the accumulation angle design of the mixed material of producing, be preferably α≤90 °-overflow solid accumulation angle β, the described solid accumulation angle β that overflows is the angle (not shown) that overflows material natural packing in blanking process, particularly, 15 °≤β≤60 °, more preferably, described flash pipe 2 and angle [alpha]≤45 ° between tube connector 1; And,
The flash collection container 3 that is arranged on flash pipe 2 outlet 21 belows, the body upper surface of this flash collection container 3 has charging aperture 31 and exhaust outlet 32, and this charging aperture 31 is communicated with flash pipe outlet 21.
Described tube connector 1 is that open at two ends, adopts the stainless steel material of resistance to chemical attack to make, and connects double screw extruder feeding machine and double screw extruder feed opening, and its cross section is rounded or square, and thickness is at 1～2mm.
Described mixed material charging aperture 11 shapes are determined by the feeding barrel shape of double screw extruder feeding machine, conventionally can be arranged to " ∞ " or " zero " shape.
Described flash pipe 2 is fixedly connected with tube connector 1 with fixed screw by flange; This flash pipe 2 is made by the stainless steel material of resistance to chemical attack, and material thickness is at 1～2mm.
Further, described charging aperture 31 is raised in the upper surface of flash collection container 3 bodies, and it is communicated with by hose connector 4 with flash pipe outlet 22.
Further, the filter 32 with some through holes is installed on the exhaust outlet on described flash collection container 3, the through hole of this filter is wanted to stop powder to fly out; Further, described filter 32 is selected industrial conventional socks formula filter, and this socks formula filter is to comprise the screen pack that some layers have tiny through hole.
Described flash collection container 3 adopts metal or macromolecular material to make.
In concrete process of implementing to produce, mixed material flows out from feeding machine, through pipeline, from the charging aperture 11 of tube connector 1 sidewall, enters tube connector 1, then through the feed opening of extruder, flow into extruder and processes; When mixed material charging is inhomogeneous or powder in the gas that carries discharge, may cause double screw extruder feed opening flash; When the material level of the mixed material overflowing is during higher than the lower edge of flash mouth 12, the mixed material that this overflows will be flow in flash collection container 3 through hose connectors 4 by flash pipe 2 automatically; The socks formula filter of installing on the exhaust outlet 32 of described flash collection container 3, pressure and atmospheric pressure in can balance flash collection container 3, avoid material because charging resistance is excessive, to stop up flash pipe 2, and filter through socks formula filter 32, can avoid powder to float in air.When flash collection container 3 is filled, dismounting hose connector 4, changes container, and the material of collecting can re-use in ad eundem recovery.During cleaning, flange and the fixed screw of dismantling on tube connector, segmentation cleaning flash pipe 2 and tube connector 1.
Technical scheme of the present invention is simple in structure, easily configuration, easy to operate, when double screw extruder feed opening mixed material flash, when the material level of charging aperture 11 is higher than the lower limb of flash mouth 12, the mixed material overflowing can flow in flash collection container 3 by flash pipe 2 automatically, the mixed material overflowing is collected by fixed container, be difficult for contaminatedly, can ad eundem recycle, economize on resources; And filter is also housed on flash collection container 3, can further avoids powder in mixed material to float in air and go, effectively improve in-situ production environment.Flash retracting device of the present invention, the flash that is mainly used in feed opening solid material reclaims, and the flash that can also be applied in the production process of similar solid material is collected.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.Those skilled in the art, read after foregoing, for multiple modification of the present invention with to substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
