Description
Technical field
The utility model relates to a kind of extruder, specifically provides a kind of split type machine barrel tapered double screw extruder.
Background technology
The machine barrel of traditional tapered double screw extruder all is to adopt global design, this machine barrel is after using one section time limit, as far back as the machine barrel homogenizing zone wearing and tearing (and always wearing and tearing occurring at homogenizing zone earlier) appear partly, had a strong impact on the quality of product when the machine barrel homogenizing zone partly may wear to a certain degree, then this machine barrel must be scrapped; This moment, the state of whole machine barrel was: homogenizing zone heavy wear, melt zone mild wear, feeding section is not wearing and tearing almost; But because homogenizing zone is the core of tapered double screw extruder, its wearing and tearing directly influence product quality, so whole machine barrel must be scrapped; Homogenizing zone length accounts for 1/3rd of whole machine barrel, and weight accounts for 1/4th of whole machine barrel, and processing capacity accounts for 1/5th of whole machine barrel; But, lose huge because its wearing and tearing will be paid the cost price more than 2/3rds.
According to the operation principle of tapered double screw extruder, the machine barrel of extruder and screw rod are divided into three big working portion, i.e. feeding section, melt zone and homogenizing zones; The effect of feeding section is the input of raw material, and the rotation of raw material by screw rod is fed forward along the screw channel and the machine barrel of screw rod, the heat preheating that raw material is also come by the conduction of machine barrel heating board at feeding section; The effect of melt zone is the fusion and the plasticizing of raw material, carries the preheating material of coming by feeding section, and through the shearing of screw rod itself and the heat of being come by the conduction of machine barrel heating board, progressively fusion and plasticizing discharged moisture and other volatile matter by steam vent simultaneously; The effect of homogenizing zone is the dispersion of homogenizing of raw material melt and component and forms melt pressure that melt this moment temperature under the high speed shear of screw rod rises suddenly, and make melt be in the state of lower temperature by the cooling of outside; Learnt that by above argumentation the technological requirement of extruder three big working portions is different, need huge heat conduction at feeding section and melt zone, then need outside cooling at homogenizing zone, the required heating and cooling of melt all are to conduct by machine barrel; Since the global design machine barrel, the heating and cooling mutual interference mutually of homogenizing zone and feeding section, melt zone, and product quality is difficult to ensure.
Summary of the invention
The utility model is at above deficiency, and a kind of reasonable in design, simple in structure, easy for installation, cost of manufacture is low, service life is of a specified duration tapered double screw extruder of split type machine barrel is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
The tapered double screw extruder of a kind of split type machine barrel, comprise frame, described frame is provided with motor, described motor connects distributor box by reduction box, described distributor box top is provided with measurement charging device, described measurement charging device top is provided with hopper, and described distributor box is connected with split type machine barrel.
Split type machine barrel comprises feeding section, melt zone and homogenizing zone, described feeding section one end connects described distributor box by connecting snap ring, one end connects described melt zone, the described melt zone other end connects described homogenizing zone, described homogenizing zone other end connecting screw rod connects by coupling flange between described melt zone and the homogenizing zone.
Melt zone is provided with exhaust apparatus and adjusting device.
Frame is provided with switch board.
Split type machine barrel arranged outside has heating circle and blower fan.
The tapered double screw extruder of split type machine barrel of the present utility model, changed the integration design of traditional machine barrel, machine barrel is designed to two parts, two-part segmentation is according to the instructions for use design of extruder, promptly homogenizing zone is divided into one section, feeding section and melt zone are divided into one section; Be provided with heat insulation layer between two parts, two parts use flange bolt to connect; With different materials, heat treated mode is also different, thereby has satisfied the different requirements of tapered double screw extruder to machine barrel according to extruder function of use different mining for two parts; This design has improved the performance of machine barrel core work part, and when one of machine barrel core inner surface brings out existing wearing and tearing and when influencing product quality, the Rotate 180 degree is unloaded in the core, can reuse, prolonged the life-span of tapered double screw extruder greatly; Simultaneously split type design has also reduced the expense of changing machine barrel; From the angle of technology, because homogenizing zone separates with feeding section, melt zone, avoided the interference of the process conditions of homogenizing zone and feeding section, melt zone, improve the accuracy of technology controlling and process, improved the quality of product and the efficient of production.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural front view of the tapered double screw extruder of a kind of split type machine barrel;
Fig. 2 is the structure right view of the tapered double screw extruder of a kind of split type machine barrel;
Fig. 3 is the structural representation of the split type machine barrel of the tapered double screw extruder of a kind of split type machine barrel.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
The tapered double screw extruder of a kind of split type machine barrel, comprise frame 1, described frame 1 is provided with motor 2, described motor 2 connects distributor box 4 by reduction box 3, described distributor box 4 tops are provided with measurement charging device 5, described measurement charging device 5 tops are provided with hopper 6, and described distributor box 4 is connected with split type machine barrel 7.
Split type machine barrel 7 comprises feeding section 71, melt zone 72 and homogenizing zone 73, described feeding section 71 1 ends connect described distributor box 4 by connecting snap ring 74, one end connects described melt zone 72, described melt zone 72 other ends connect described homogenizing zone 73, described homogenizing zone 73 other end connecting screw rods 75 connect by coupling flange 76 between described melt zone 72 and the homogenizing zone 73.
