Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of filter, particularly a kind of filter of extruder.
Background technology
In plastic extruding forming equipment, plastic extruder is referred to as main frame conventionally, and the follow-up equipment plastic extruding forming machine supporting with it is called subsidiary engine.
Extruder comprises frame and screw rod, has charging aperture and discharging opening in frame, and existing extruder comprises single screw rod, twin-screw and multiscrew, and charging aperture is connected with feed pipe, and discharging opening is connected with discharge nozzle.Be most widely used with single screw extrusion machine at present, be suitable for the processing of extruding of general material.Double screw extruder have the shearing less by fricative heat, material is suffered relatively evenly, the conveying capacity of screw rod is large, extrusion capacity is more stable, material stops and grows in machine barrel, mixes, be also widely used.The place that multiscrew takies is larger, and more complicated, uses less.
But no matter be single screw rod, twin-screw or multiscrew, the melt that extruder forms after plastic grain is melted always has the foreign matter such as impurity, gel particles and exists, therefore must filter the melt of extruding, existing filter is only to filter once, poor filtration effect.
Summary of the invention
There are the problems referred to above for existing technology in the utility model, has proposed a kind of filter, and this filter uses the different screen pack of multilayer order number to filter layer by layer, good filtration effect.
The purpose of this utility model can realize by following technical proposal: a kind of filter, comprise filter body, described filter body vertically has the opening running through, it is characterized in that, described filter body along continuous straight runs has insertion groove one, insertion groove two and insertion groove three, and insertion groove one, insertion groove two and insertion groove three are vertically arranged in order from top to bottom, in described insertion groove one, be inserted with installing frame one, in described insertion groove two, be inserted with installing frame two, in described insertion groove three, be inserted with installing frame three, described installing frame one fixedly connected to the inner side screen pack one, described installing frame two fixedly connected to the inner side screen pack two, described installing frame three fixedly connected to the inner side screen pack three, described screen pack one, the order number of screen pack two and screen pack three becomes many successively, described installing frame one, installing frame two and installing frame three be interior all has support bar, described support bar is positioned at screen pack one, the below of screen pack two and screen pack three, and with screen pack one, the lower surface of screen pack two and screen pack three fits.
The melt that extruder is extruded enters into the opening of filter body, opening is fixed with screen pack one from the top down successively, screen pack two and screen pack three, and screen pack one, the order number of screen pack two and screen pack three becomes many successively, it is the filter opening footpath that the filter opening footpath of screen pack one is greater than screen pack two, the filter opening footpath of screen pack two is greater than the filter opening footpath of screen pack three, in the time filtering, screen pack one first filters out the impurity of diameter maximum, screen pack two is after filtering the middle impurity of diameter, last screen pack three filters out the impurity of diameter minimum, make not contain in melt impurity, use the screen pack of three kinds of different meshes to filter successively, filter out successively the different impurity of diameter, with different levels filtration, that filters is more thorough, and make screen pack one, screen pack two and screen pack three are difficult for stopping up, and screen pack one, the quantity of the impurity filtering on screen pack two and screen pack three is substantially similar, and due to installing frame one, the effect that the frame of installing frame two and installing frame three surrounds, impurity can only be positioned at screen pack one, the top of screen pack two and screen pack three, it is screen pack one, screen pack two and screen pack three clean simultaneously, the number of times cleaning is few, can not incur loss through delay the normal work of extruder.And due to the existence of support bar, support bar plays the effect of support to screen pack one, screen pack two and screen pack three, make screen pack one, screen pack two and screen pack three can not cave in and be collapsed by pressure, screen pack one, screen pack two and screen pack three long service life, good filtration effect.
In above-mentioned a kind of filter, described installing frame one, installing frame two and installing frame three is embedded in respectively in described filter body, and installing frame one and insertion groove one, installing frame two and insertion groove two, installing frame three and the basic tight fit of insertion groove three.Basic tight fit setting, makes the gap between installing frame one, installing frame two and installing frame three and filter body little, and melt can not flow out the gap between installing frame one, installing frame two, installing frame three and filter body.
In above-mentioned a kind of filter, the quantity of described support bar is 4-16 root, and described any two support bars are vertical or be arranged in parallel, and the support bar spaced set arranging in the same way.Support bar is crisscross arranged, and the support force that screen pack one, screen pack two and screen pack three each positions are subject to is basic identical, and the support effect of support bar is good, and screen pack one, screen pack two and screen pack three can not damage, long service life.
In above-mentioned a kind of filter, it is locking strip that described installing frame one, installing frame two and installing frame three is exposed at the external part of filter, and described locking strip is connected mutually by bolt and filter body.Be connected by bolt-locking, installing frame one, installing frame two and installing frame three can not be moved, good stability.Locking strip has expanded the area of locking, facilitates the locking of bolt, and locking strip plays the effect in shutoff gap, and melt can not flow out from this gap.
In above-mentioned a kind of filter, described screen pack one, screen pack two and screen pack three are made by stainless steel material.Stainless steel stable in properties, and intensity is high, can not be corroded, the distortion that also can not be pressed.
In above-mentioned a kind of filter, the bottom of described opening is tapered.The tapered melt being conducive to after filtration better flows out.
Compared with prior art, the filter of this extruder has the following advantages:
1, in the filter of this extruder, be provided with multiple filtration net, and the order number of screen pack becomes many from top to bottom successively, successively the impurity of different sizes is filtered good filtration effect.
In the installing frame of the filter of 2 extruders, be provided with support bar, screen pack played to the effect of support, screen pack can not collapsed by pressure, can not be out of shape screen pack long service life, good filtration effect.
3, this filter carries out after multiple filtration melt out from extruder, and the impurity on every layer of screen pack is basic identical, can clean simultaneously, effectively reduces the number of times that cleans dismounting, improves the service efficiency of extruder.
