Description

For the filter for installation of plastic extruder
Technical field
The utility model relates to a kind of filter for installation for plastic extruder, belongs to field of plastics processing.
Background technology
At present, often need to use plastic extruder in plastics-production process.In order to ensure the quality of plastic product, screen pack being installed usually in the head of plastic extruder with the various impurity in filtering plastic melt and dirt, and improving the mixed effect of plastic melt, thus obtaining pure plastic product.When plastic raw materials is cleaner, this filter can keep the production of certain hour continuously, its screen pack not easily blocks, the time of filter screen replacement is relatively long, but because present many plastic extruders carry out regenerated plastics production with the second-hand waste or used plastics retrieved, containing various impurity in the second-hand waste or used plastics retrieved, particularly various small metal impurities etc., be difficult to clean out with artificial or additive method before second-hand waste or used plastics is reproduced production, therefore more or less can bring in the machine of production, in fact it is a lot of for containing various minute impurities in the second-hand waste or used plastics retrieved, the screen pack in the filter on plastic extruder front end will be caused so often to be blocked by impurity, the shutdown of just having to of such plastic extruder gets off to clear up screen pack or to change screen pack, work consuming very consuming time.
The Problems existing of existing plastic extruder is: the screen pack installed in plastic extruder only has a kind of screen pack of order number, and is single layer filter, can reduce filter effect, can not meet the needs producing meticulous plastic product when the filter bores of screen pack is excessive; And the filter bores of screen pack too small time often cause screen pack to block problem, have impact on normal production, reduce production efficiency.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of reasonable in design, ensure product quality the filter for installation for plastic extruder of enhancing productivity, it can decrease plastic extruder and shut down the number of times that cleaning changes.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of filter for installation for plastic extruder, comprise front screen modules, rear screen modules, filter hood, flow-guiding channel, three-way body and threeway lid, described filter hood has open front and after-opening, described front screen modules and after-filter assembly are separately positioned on open front and after-opening, there is in described filter hood cavity one, described three-way body has open-ended hollow lug boss, described filter hood to be installed in lug boss and to be connected with the inner wall sealing of lug boss, in described threeway lid, there is the recess matched with lug boss, cavity two is formed between described recess and lug boss top, described after-filter assembly forms cavity three in lug boss and between lug boss, described threeway covers has charging hole, described charging hole and cavity two conducting, described cavity two and cavity three are by flow-guiding channel conducting, described filter hood has filter hood discharge opening, on described three-way body, corresponding filter hood discharge opening place has three-way body discharge opening, described threeway covers corresponding three-way body discharge opening and has threeway lid discharge opening.
As a kind of preferred version of the present utility model, described water conservancy diversion is logical can be mozzle, described front screen modules offers front screen pack through hole, rear screen modules offers rear screen pack through hole, and described mozzle is installed in front screen modules and rear screen modules through front screen pack through hole and rear screen pack through hole.
Further, described front screen pack through hole is arranged on the center of front screen modules, and described rear screen pack through hole is arranged on the center of rear screen modules.
As another kind of preferred version of the present utility model, described flow-guiding channel can also be three-way body pod apertures, and described three-way body pod apertures is opened on three-way body, and one end of described pod apertures is communicated with cavity two, the other end and cavity tee joint.
In order to better filtration, described front screen modules and rear screen modules include the screen pack of at least two-layer different meshes.
Further, described front screen modules and the screen pack of rear screen modules include 40 order screen packs and 200 order screen packs.
Further, described front screen modules is followed successively by 40 order screen packs and 200 order screen packs by cavity two to cavity one direction, and described rear screen modules is followed successively by 40 order screen packs and 200 order screen packs by cavity three-dimensional cavity one direction.
Further, described lug boss is frustum, and lug boss inwall is that cylindrical, described filter hood is also cylindrical in what mate with lug boss inwall.
The beneficial effects of the utility model are; the filter for installation for plastic extruder that the utility model adopts has front screen modules and rear screen modules; the raw material of plasticizing can be divided into two parts press filtration respectively; reduce the probability of plasticizing raw material due to impurity blocking screen pack; extend the work service time of filter; decrease the number of times that cleaning replacing shut down by plastic extruder, improve operating efficiency, also improve the service life of screen pack.Front screen modules and rear screen modules are the screen pack of multilayer many orders number, can multiple times of filtration by different level, both can not because of the excessive reduction filter effect of the filter bores of screen pack, and the needs producing meticulous plastic product can not be met, the problem that screen pack will be caused often to block because the filter bores of screen pack is too small again and have impact on normal production, improves production efficiency.
