Description

technical field

[0001] The invention belongs to the technical field of filter devices, in particular to a filter device for a recycled plastic granulator and a filter extruder head containing the filter device. Background technique

[0002] At present, the raw materials used for granulation by recycled plastic granulators generally use waste plastics such as waste plastic bags and waste plastic cloths as raw materials. , some impurities mixed with lime sand isosceles to block the filter screen, so that the equipment cannot work normally. The solution is to stop the machine to remove the impurities and continue production. Every time the impurities are removed, a large amount of them needs to be burned (wasted) and left in the equipment. The plastic raw material in the cavity is labor-intensive, time-consuming, and has low production efficiency and high production cost. Contents of the invention

[0003] The purpose of the present invention is to provide a filtering device...

Examples

Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see figure 1 — Figure 7 :

[0030] The filter device 01 is formed with several filter groups 15 evenly distributed on the substrate to form a filter screen 10, each filter group 15 is arranged at intervals by several filter holes 11 or 12 and 13, and the outer contour of each filter group 15 is a geometric figure .

[0031] The bottom of the above-mentioned filter screen 10 is provided with a support discharge mechanism, and the specific structure of the support discharge mechanism is: the substrate is provided with several large through holes 21 corresponding to each of the filter groups 15 to form a reinforcement net 20, Each large through hole 21 corresponds to a filter group 15 and does not block all filter holes 11 or 12 and 13 on the filter group 15; or

[0032] The specific structure of the supporting discharge mechanism is: several suppor...
