Abstract
The utility model provides a multistage extruder of serial -type, because first extruder is 451-551 with the draw ratio of second extruder, the screw rod diameter of third extruder is greater than the screw rod diameter of first extruder and second extruder, therefore, the dwell time of material in the extruder has been improved by a wide margin, can make the reaction of material intensive mixing, additionally, owing to set up cooling device at each linkage segment, when cooling off the screw rod, water gets into coolant tank by the inlet tube, and through the water of water pump in with coolant tank take out send into the cavity in the corresponding screw rod through the connecting pipe in, cool off the screw rod, be provided with water temperature sensor in the coolant tank, can transmit the temperature for the control unit in real time, when the temperature of sensing is higher than the settlement temperature, the control unit control solenoid opens, thereby advance cold water in the regulation water pipe to the coolant tank in, mix the back with the water in the coolant tank, reduce the temperature in the coolant tank, therefore, the temperature that can effectively guarantee the screw rod is unlikely to too high and influences the quality of product.
Description
Technical field
The utility model relates to a kind of tandem type multi-stage extruder.
Background technology
Carrying out reactive extrursion processing with extruder to polymer can continuous prodution, and equipment investment is little, output is high, thus apply very extensive, but reactive extrursion requires that material needs sufficient incorporation time, therefore, the time of staying is long, this just requires that screw slenderness ratio is long as much as possible, but be at present no matter singe screw or twin-screw and multiscrew, draw ratio is all less, be difficult to get to the very long time of staying, therefore, reaction conversion ratio is lower, monomer residue is more, the response type polymer that ask for something is higher can not be prepared, limit the range of application of reactive extrursion, in addition, due to when extruder works, its screw rod can produce larger heat, the heat that its running produces is often high than the temperature of subscribing, therefore, for ensureing the quality of extruded product, need to cool the screw rod run up, to ensure product quality, but, all adopt running water to cool at present, and the water temperature of running water is difficult to control, cooling effect is bad, therefore, is difficult to ensure product quality.
Utility model content
The utility model aims to provide a kind of good cooling results and effectively improves residence time of material, makes the well-mixed tandem type multi-stage extruder of material, to ensure the quality of product.
A kind of tandem type multi-stage extruder described in the utility model, comprise the first extruder, second extruder and the 3rd extruder, the head of described first extruder is connected with the second section machine barrel lateral seal of the second extruder, the head of the second extruder is connected with the second section machine barrel lateral seal of the 3rd extruder, the linkage section of the second section machine barrel of the linkage section of the head of the first extruder and the second section machine barrel of the second extruder and the head of the second extruder and the 3rd extruder is respectively arranged with heater, the draw ratio of the first extruder and the second extruder is 45/1 ~ 55/1, the screw diameter of the 3rd extruder is greater than the screw diameter of the first extruder and the second extruder, the outer surface of described heater is provided with cooling device, described cooling device comprises cooling water tank, the upper end of cooling water tank is provided with water inlet pipe, the bottom of cooling water tank is provided with outlet pipe, outlet pipe is provided with water pump, water pump is connected with the cavity in corresponding screw rod by tube connector, described cooling water tank lower end is provided with the cooling-water temperature sensor being connected to control unit, cooling water tank upper end is provided with adjustment water pipe, adjustment water pipe is provided with the magnetic valve being connected to control unit.
A kind of tandem type multi-stage extruder described in the utility model, because the draw ratio of the first extruder and the second extruder is 45/1 ~ 55/1, the screw diameter of the 3rd extruder is greater than the screw diameter of the first extruder and the second extruder, therefore, significantly improve the time of staying of material in extruder, the abundant hybrid reaction of material can be made, in addition, owing to being provided with cooling device at each linkage section, when cooling screw rod, water enters cooling water tank by water inlet pipe, and the water in cooling water tank is pumped through in the cavity that tube connector sends in corresponding screw rod by water pump, screw rod is cooled, cooling-water temperature sensor is provided with in cooling water tank, in real time water temperature can be passed to control unit, when the water temperature sensed is higher than design temperature, control unit Controlling solenoid valve is opened, thus enter cold water in adjustment water pipe in cooling water tank, after mixing with the water in cooling water tank, reduce the water temperature in cooling water tank, therefore, effectively can ensure that the temperature of screw rod is unlikely to too high and affects the quality of product.
