Description
Technical field
The utility model relates to macromolecular material, plastic, rubber processing equipment technical field, especially a kind of automatic fitration type single screw extruder barrel.
Background technology
waste old, plastics and chemical fibre composition are more assorted, impurity cleans and is difficult for thoroughly, be called as patent No. 200620077863.X name in the Chinese utility model of " uninterrupted net replacer for screw extruder in plastic board producing line " and disclose a kind of structure for high molecular plastics and rubber glue charging filter progress, it is characterized in that it comprises: Hydraulic Station, net-changing device and a left side, right connecting pipe, net-changing device comprises oil cylinder, the draping plate, connector and support, cylinder apparatus is on support, draping plate top is connected with cylinder piston rod through connector, on having on the draping plate, lower two opening of sieves, let slip filter screen in the hole, the draping plate is arranged at a left side, between right connecting pipe, oil cylinder is connected with Hydraulic Station.When changing filter screen in process of production, change with two states in the HYDRAULIC CONTROL SYSTEM net-changing device, these present two filter screen type drapings must cause plastic melt not extrude continuously processing, cause disconnected bar or produce raw product again.More can not adapt to the more technics of reclaim of plastic waste regeneration processing of impurity, impurity is too much, and too high with the board-like draping frequency of prior art, must cause can not normal process production.
In sum, existing plate type hydraulic net exchanging device can't be guaranteed that plastic melt is worked continuously and extrude, must cause disconnected bar or produce waste product, more can't adapt to the technological requirement that the more technics of reclaim of plastic waste of impurity is processed again, therefore a kind of new technology that addresses the above problem of necessary release.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of automatic fitration type single screw extruder barrel for the above-mentioned state of the art, it can adapt to the processing of working continuously again of the more plastic melt of impurity, allows the plastic melting physical efficiency not produce with extruding processing break bar or waste product continuously.
the utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of automatic fitration type single screw extruder barrel, comprise a machine barrel body with discharging opening, it is characterized in that: be lined with the filtration lining on the inwall of described machine barrel body, the described machine barrel body right side connects the screw rod that is provided with threaded structure, described filtration lining is provided with and is communicated with the discharging lining, the described machine barrel body right side connects the screw rod that is provided with threaded structure, described filtration lining is provided with the filtration outer wall that is communicated with blow tank, the inwall circumference of described filtration lining is provided with filter bores, described filtration lining is fixed on the machine barrel inner body wall by fixture, the left port of described machine barrel body is provided with the nose cover with standby discharging opening, described nose cover is in mating connection by fixture and this body space of machine barrel, the right output port of described machine barrel body is connected with screw rod by fixture.
As improvement, described blow tank inclination angle at an angle.
As improvement, described filtration lining is fixed on the inwall of machine barrel body by alignment pin.
As improvement, the described standby outlet material mouth that is arranged on nose cover is the conical surface with the transition face that filters lining, and described nose cover is fixedly connected by screw and machine barrel body, and the right output port of described machine barrel body fixes by screw and screw rod.
Compared with prior art, the utility model has the advantage of: because the inwall of described filtration lining arranges filter bores, assurance melt material filters to be extruded, described filtration lining fixes by the inwall of alignment pin and machine barrel body, after melt is sheared automatically after filtration the lining blow tank reserve cylindrical shell, and the left port of described machine barrel body is provided with the nose cover with standby discharging opening, standby discharging opening remains in the escape truck of the melt in machine barrel as cleaning, when being convenient for changing cleaning filtration lining, the melt that remains in machine barrel is passed through from standby discharging opening.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is along the profile of A-A;
Fig. 3 is that the utility model is along the profile of B-B in Fig. 2;
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
as Fig. 1, shown in 2, a kind of automatic fitration type single screw extruder barrel, comprise a machine barrel body 1 with discharging opening 3, discharging opening 3 is mutual vertical configuration with machine barrel body 1, be lined with on the inwall of machine barrel body 1 and filter lining 2, alignment pin 8 passes the through hole that filters lining 2 left end both sides, thereby will filter on the inwall that lining 2 directly is fixed on machine barrel body 1, described filtration lining 2 is provided with the filtration outer wall 5 that is communicated with blow tank 7, wherein blow tank 7 is connected with discharging opening 3 and is certain inclination angle, to facilitate the melt material naturally to flow out smoothly outside machine barrel body 1, the inwall circumference of described filtration lining 2 is provided with filter bores 6, the left port of machine barrel body 1 is provided with the nose cover 10 with standby discharging opening 9, nose cover 10 is connected by screw 11 and machine barrel body 1 phase gap, wherein, standby discharging opening 9 is the conical surface with the transition face 12 that filters lining 2, work to stop the melt material, standby discharging opening 9 is escape trucks of clearing up residual melt when lining 2 is filtered in cleaning as changing, the right output port of machine barrel body 1 is connected with the screw rod 4 that is threaded structure by screw 11, and screw rod 4 plays and shears centrifugal effect through the design of afterbody 6D to 8D, and wherein D is the diameter of screw rod 4.
During work, machine barrel body 1 rotates to be expressed into through screw rod 4 and filters lining 2 places, design through screw rod tail 6D to 8D, screw rod plays a part to shear centrifugal, and under the stopping of the transition face 12 of nose cover 10, the melt material oozes out along filter bores 6 places of filtering on lining 2, thereby impurity is filtered at the inwall that filters lining 2, and the inwall that filters lining 2 is guaranteed suitable thickness, to guarantee that impurity can be not overflowed, melt material after filtration flows out outside machine barrel body 1 naturally by blow tank 7, thereby reaches automatic fitration, the purpose of working continuously.
