Abstract
The utility model discloses an internal-heating plastic extruder. The internal-heating plastic extruder comprises an enclosure (1), and is characterized in that a heating layer (4) is arranged outside the enclosure (1), wherein an extruding screw (2) is arranged in the enclosure (1); a motor (3) is connected at one side of the extruding screw (2); the other end of the extruding screw (2) is connected with a bearing base (10); a cavity (5) is arranged in the extruding screw (2); an oil guide tube (7) is arranged in the cavity (5); the oil guide tube (7) penetrates out of a bearing base (3); and the side wall of the enclosure (1) is connected with a heating oil tank (8). According to the utility model, the oil guide tube is simple in structure, does not generate faults easily and can work for a long time without maintenance in comparison with an electric heating tube and an electric heating wire. Compared with the prior art, the internal-heating plastic extruder disclosed by the utility model has the advantages of being simple in structure, high in heating efficiency, uniform in heating, convenient to maintain, and the like.
Description
Technical field
The utility model relates to a kind of interior heating of plastic extruder, belongs to plastic extruder technical field.
Background technology
In prior art, plastic extruder generally adopts the mode of heating of casing outside.Shortcoming is that interior external heat is inhomogeneous, extrudes effect bad.Therefore some plastic extruder adds the heating element heater such as resistance wire, electrothermal tube in extrusion screw rod inside, make the inside and outside homogeneous heating of plastic extruder, but resistance wire, electrothermal tube structure complexity, element easily damages, cause the interior heating-up temperature of screw rod unstable, therefore need frequent replacing, and electrothermal efficiency is low, cost is higher.
Utility model content
The purpose of this utility model is: a kind of interior heating of plastic extruder is provided, and firing rate is fast, more evenly to overcome the deficiencies in the prior art.
The utility model is achieved in that interior heating of plastic extruder, it comprises casing, be provided with zone of heating outward at casing, in casing, be provided with extrusion screw rod, one side of extrusion screw rod connects motor, and the opposite side connecting axle bearing of extrusion screw rod, is provided with cavity in extrusion screw rod, oil guide pipe is set in cavity, and the sidewall that oil guide pipe passes bearing block, casing is connected with heating fuel tank.
Aforesaid interior heating of plastic extruder, described extrusion screw rod is provided with temperature inductor.
Aforesaid interior heating of plastic extruder, arranges U-shaped oil guide pipe in described extrusion screw rod.
Aforesaid interior heating of plastic extruder, the linkage section of described oil guide pipe and heating fuel tank is provided with insulating tube.
Oil guide pipe of the present utility model can pack deep fat into, heating simultaneously inside and outside interior heating of plastic extruder, and homogeneous heating, the thermal efficiency of conduction oil is higher, and use cost is lower.Meanwhile, oil guide pipe simple in structure, same to electrothermal tube, heating wire are compared, and are difficult for breaking down, can long-term work and need not keep in repair.Compared with the existing technology, the utlity model has simple in structurely, the thermal efficiency is high, homogeneous heating, the advantage such as easy to maintenance.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment of the present utility model: interior heating of plastic extruder, make the casing 1 of extruder, at the outer installation zone of heating 4 of casing 1, at the interior installation extrusion screw rod 2 of casing 1, a side of extrusion screw rod 2 connects motor 3, the opposite side connecting axle bearing 10 of extrusion screw rod 2, extrusion screw rod 2 can be rotated, in extrusion screw rod 2, produce cavity 5, at the interior installation oil guide pipe 7 of cavity 5, the sidewall that oil guide pipe 7 passes bearing block 3, casing 1 is connected with heating fuel tank 8.In the middle of bearing block 3, through hole is set, is connected with oil guide pipe 7 by mounting disc 11 at the sidewall of casing 1.Extrusion screw rod 2 interior employings be U-shaped oil guide pipe 7, two mouths of pipe of U-shaped oil guide pipe 7 are connected with heating fuel tank 8, complete the circulation of conduction oil in one end of extruder.
Multiple temperature inductors 6 are installed on extrusion screw rod 2, can be detected the temperature of each section of extrusion screw rod 2, temperature control regulates more accurate.
At oil guide pipe 7 and the linkage section of heating fuel tank 8, insulating tube 9, heat preservation energy-saving are also set.
When work, plastics are put into heating of plastic extruder, plastics are heated by zone of heating 4 and oil guide pipe 7 simultaneously.And the temperature of monitoring according to temperature inductor 6, adjust in time the temperature of conduction oil in oil guide pipe 7.
