Abstract
The utility model relates to a filtering device for a thermoplastic double-screw extruder, which comprises a net frame and a filter screen. The filtering device is characterized in that the net frame (1) adopts a cuboid provided with through-holes (2), the filter screen (3) matched with the through-holes (2) is arranged in the through-holes (2), a filter auxiliary screen (4) attached to the filter screen (3)can further be arranged on one side of the filter screen (3), the filter auxiliary screen (4) is equal to the filter screen (3) in size, the filter screen (3) is fixed with the filter auxiliary screen (4) through a rivet (6), and the rivet (6) is arranged at the circular centers of the filter screen (3) and the filter auxiliary screen (4). The filtering device not only can increase the filtration area, but also can reduce the volume of the filtering device. Moreover, as the size of filtering holes can be adjusted in a dynamic manner, filtering is facilitated, thereby contributing to improved production efficiency.
Description
Technical field
The utility model relates to a kind of double screw extruder, relates in particular to a kind of thermoplastic materials double screw extruder filter.
Background technology
Existing double screw extruder filter places extruder head inside on the market, and the rack of filter is a cylinder, has ellipse hole on the rack, and the screen pack that matches with through hole is arranged in the through hole.This area of filter net is little, and filter opening is few on the screen pack, easily blocks, and draping is frequent, and production efficiency is low.If increase the volume that the area of screen pack then needs to increase greatly rack and head, increased the cost of filter itself and extruder.
The utility model content
The purpose of this utility model provides the double screw extruder filter that a kind of filter area is big, volume is little.
In order to reach above purpose, the utility model adopts following technical scheme:
A kind of double screw extruder filter comprises rack and screen pack, and described rack is the cuboid with through hole, is provided with the screen pack that matches with through hole in the described through hole.
In order to make filtering holes to adjust dynamically, the utility model is done further improvement: a side of described screen pack is provided with the auxiliary net of the filtration of fitting with described screen pack, the auxiliary net size of described filtration is identical with screen pack, the auxiliary Netcom of described screen pack and described filtration crosses rivet and fixes, and rivet is located at the described screen pack and the center of circle of filtering auxiliary net.
For the ease of filtering the rotation of auxiliary net, the utility model can be done further improvement: described aided filter net surface is provided with projection.
In order to realize uninterrupted production, the utility model can be done further improvement: described rack is provided with plural through hole.
The beneficial effects of the utility model are:
(1) because rack has adopted the structure of cuboid, the corresponding filter area that increased makes that screen pack is difficult for blocking, and production efficiency is improved, and has reduced the volume of filter simultaneously.
(2) because filter element has adopted screen pack and filtered the mode that auxiliary net combines, make that the size of filtering holes can be adjusted dynamically, dwindled the maximum radius that to filter object, made things convenient for the operation of filtering.
(3) because the aided filter net surface is provided with projection, make convenient, quick when filtering auxiliary net rotation, reduced the time of adjusting, increased production efficiency.
(4) because rack is provided with plural through hole, when work, can realize continual production like this, improved production efficiency.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the vertical view along A-A ' direction of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
Embodiment 1: as shown in Figure 1: a kind of double screw extruder filter, comprise rack and screen pack, and described rack 1 is provided with the screen pack 3 that matches with through hole 2 for having the cuboid of through hole 2 in the described through hole 2.Rack 1 adopts the structure of cuboid, and only the length of need increase rack 1 and wide just can obtain bigger filter area, and the volume of filter integral body does not have bigger increase.One side of described screen pack 3 is provided with the auxiliary net 4 of filtration of fitting with described screen pack 3, auxiliary net 4 sizes of described filtration are identical with screen pack 3, described screen pack 3 is fixing by rivet 6 with the auxiliary net 4 of described filtration, and rivet 6 is located at the described screen pack 3 and the center of circle of filtering auxiliary net 4.Also can adopt modes such as bolt to be connected between screen pack 3 and the screen pack 4.When the auxiliary net 4 of filtration overlaps fully with screen pack 3, the radius that can filter largest object just is the radius of respective aperture on the screen pack, when filtering auxiliary net 4 with screen pack 3 incomplete coincidences, the radius that can filter largest object promptly only needs the auxiliary net 4 of rotating filter can obtain different filtration radiuses with regard to corresponding minimizing.Described aided filter net 4 surfaces are provided with projection 5.It is more convenient, laborsaving that projection 5 can make when rotating filter is auxiliary to be netted.Rack is provided with plural through hole 2, after one of them through hole 2 blocks, can use the operation that other through hole 2 filters instead, has realized continual production, has improved the efficient of producing.
Claims (4)
1, a kind of double screw extruder filter comprises rack and screen pack, it is characterized in that: described rack (1) is provided with the screen pack (3) that matches with through hole (2) for having the cuboid of through hole (2) in the described through hole (2).
2, double screw extruder filter according to claim 1, it is characterized in that: a side of described screen pack (3) also is provided with the auxiliary net (4) of the filtration of fitting with described screen pack (3), described filtration assists net (4) size identical with screen pack (3), described screen pack (3) is fixing by rivet (6) with the auxiliary net (4) of described filtration, and rivet (6) is located at the described screen pack (3) and the center of circle of filtering auxiliary net (4).
3, double screw extruder filter according to claim 2 is characterized in that: described aided filter net (4) surface is provided with projection (5).
