Description
Technical field
The present invention relates to a kind of extruder, refer to especially a kind of side charging extruder.
Background technology
Extruder is a kind of conventional equipment in current plastics recovery, this extruder has stricter requirement for the water content of used plastic raw materials, therefore, general extruder plastic raw materials used all will be processed and just can use through super-dry in advance, once raw material water content exceedes the scope of application, affect the water content of plastic pellet after extruding pelletization.Therefore, current extruder still has many condition restriction in the use, and need to be equipped with multiple corollary equipments.
Summary of the invention
Technical problem to be solved by this invention is: a kind of side charging extruder is provided, and this side charging extruder is applicable to the extruding pelletization of the higher plastic raw materials of water content, thereby the operation of shortening extruding pelletization reduces the instructions for use of plastic raw materials.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of side charging extruder, comprise frame, extruded tube, extrusion screw rod, extrusion screw rod power set, described extruded tube is fixed in frame, extrusion screw rod rotates and is installed in extruded tube, this extrusion screw rod and extrusion screw rod power set are in transmission connection, the downstream of described extruded tube is provided with discharging opening, the tract of extruded tube is provided with heater that material in extruded tube is heated and the vacuum extractor to extruded tube internal suction, on the sidewall of described extruded tube, be provided with charging aperture, this charging aperture is communicated with side feed arrangement, this side feed arrangement comprises the feeding cylinder being fixedly connected with extruded tube, this feeding cylinder is vertical with extruded tube to be arranged, the upper end of feeding cylinder is provided with feed hopper, on the barrel of feeding cylinder, be provided with several treatment holes, in extruded tube, be rotatablely equipped with charging and extract screw rod, this charging is extracted screw rod and is driven by charging power set.
As the preferred scheme of one, described treatment hole is evenly arranged at barrel the latter half of feeding cylinder.
As the preferred scheme of one, between described feeding cylinder and extruded tube, be fixedly connected with by threeway adapter sleeve.
As the preferred scheme of one, the below of described feeding cylinder is provided with drip pan.
As the preferred scheme of one, described charging is extracted screw rod the anti-feeding back device that prevents material feed back is being installed away from one end of extruded tube.
As the preferred scheme of one, described anti-feeding back device comprises anti-feed back spacer, terminal pad and spacer pressing plate, described terminal pad is connected feeding cylinder with the casing of charging power set, on described terminal pad, be provided with endoporus, the axle head that screw rod is extracted in described charging runs through endoporus and is connected with the output shaft of charging power set, the downstream of described terminal pad is provided with spacer caulking groove, described anti-feed back spacer is set in axle head and is close to axle head, and described spacer pressing plate is sleeved on axle head and with terminal pad is fixing anti-feed back spacer is constrained in spacer caulking groove.
Adopt after technique scheme, effect of the present invention is: carry out side charging because this extruder adopts side feed arrangement, when the higher material that water content is higher enters in feeding cylinder from feed hopper, charging is extracted screw rod and material is pushed in feeding cylinder and be fed forward, material dewatering in extrusion process, moisture flows out from treatment hole, thereby the object of the dehydration reaching, like this, the material that water content is moderate is fed to be extracted screw rod and joins in extruded tube, be fed forward by the extrusion screw rod in extruded tube, through heating plasticizing, vacuumize after moisture absorption, finally can complete granulation by pellet device.The directly charging of material that water content is higher, without additionally dehydrating processing, shortens the operation of extruding pelletization, reduces the instructions for use of plastic raw materials.Also without supporting other dehydration equipments, reduce cost simultaneously.
Again owing to being fixedly connected with by threeway adapter sleeve between described feeding cylinder and extruded tube.This structure makes the fixed installation of feeding cylinder and extruded tube very easy.
Again because described charging is extracted screw rod the anti-feeding back device that prevents material feed back is being installed away from one end of extruded tube, the axle head of avoiding water-containing materials to extract screw rod along charging enters in charging power set and causes it to damage, and improves the functional reliability of equipment.
