Abstract
The utility model relates to an entire machine head cooling structure of an extruder. The entire machine head cooling structure of the extruder comprises an extrusion cylinder and an extrusion end surface which is arranged at the end part of the extrusion cylinder through a fastener, wherein a certain number of extrusion holes are uniformly arranged on the extrusion end surface, and an interlayer structure is arranged inside the side wall of the extrusion cylinder; and a water inlet and a water outlet are arranged on the extrusion cylinder, and an annular cooling water path is arranged inside the extrusion end surface, and is communicated with the interlayer structure. According to the entire machine head cooling structure of the extruder, the cooling water path is arranged in the extrusion end surface, and is communicated with the interlayer structure inside the extrusion cylinder, so that the end surface is cooled, the temperature of the end surface when the machine head works can be substantially reduced, and significance of the stability of pharmaceutical preparations and the production increase is important.
Description
Technical field
The utility model relates to the pharmaceutical manufacturing apparatus technology, particularly relates to a kind of complete machine head cooling structure of extruder.
Background technology
Extruder is used more extensive at pharmaceutical field, because the head position of extruder adopts the spiral end face to extrude, pressure is bigger; The heat that produces is more, the thermal sensitivity medicine is had very big influence, for the influence that guarantees that medicine is not heated; Generally all will cooling structure be set at the head position of extruder, existing extruder generally just is provided with interlayer in extruding cylindrical shell, through cooling water to circulate be that head is lowered the temperature; Find through long-term test; Head produces the maximum place of heat in when work and is to extrude end face, and existing cooling structure rarely has end face is cooled off, and haves much room for improvement.
The utility model content
The utility model proposes a kind of complete machine head cooling structure of extruder for addressing the above problem.
The technical scheme of the utility model is: a kind of complete machine head cooling structure of extruder; Contain and extrude cylindrical shell, extrude end face; Extrude end face and be installed in the end of extruding cylindrical shell through securing member; The described extrusion cavities that is evenly equipped with some on the end face of extruding, the described interior of extruding cylindrical shell is a sandwich, is provided with water inlet and delivery port on the cylindrical shell extruding; The described end face inside of extruding is provided with the annular cooling water road, and this annular cooling water road is communicated with above-mentioned sandwich.
Be provided with isolating bar in the described sandwich, this interlayer is separated into into the water interlayer and goes out water interlayer two parts.
Described annular water route is looped around the outside of extrusion cavities distributed areas.
The beneficial effect of the utility model
The complete machine head cooling structure of the extruder of this utility model; In extruding end face, be provided with cooling water channel; And be communicated with sandwich in extruding cylindrical shell; Realized the cooling of end face, the temperature in the time of can reducing head work significantly on the end face, significant to raising stability, output of pharmaceutical preparation.
Description of drawings
Fig. 1 is the structural representation of the complete machine head cooling structure of this extruder;
Fig. 2 is the A-A cross section structure sketch map of Fig. 1;
Fig. 3 is the B-B cross section structure sketch map of Fig. 1.
Among the figure 1. extrude cylindrical shell, 2. extrude end cap, 3. securing member, 4. the annular cooling water road, 5. water inlet, 6. delivery port, 7. the water inlet interlayer, 8. go out water interlayer, 9. extrusion cavities.
The specific embodiment
Embodiment: referring to Fig. 1; A kind of complete machine head cooling structure of extruder among the figure; Contain and extrude cylindrical shell, extrude end cap, extrude end face and be installed in the end of extruding cylindrical shell, the described extrusion cavities that is evenly equipped with some on the end face of extruding through securing member; The described interior of extruding cylindrical shell is a sandwich, is provided with water inlet and delivery port on the cylindrical shell extruding; The described end cap inside of extruding is provided with the annular cooling water road, and this annular cooling water road is communicated with above-mentioned sandwich.Be provided with isolating bar in the described sandwich, this interlayer is separated into into the water interlayer and goes out water interlayer two parts.Described annular water route is looped around the outside of extrusion cavities distributed areas.
