Abstract
The utility model relates to a vacuum pelletizing port return prevention device for a double-screw extruder, which comprises a water tank. The water tank is positioned inside a casing of the double-screw extruder, a first evacuation port of the water tank is communicated with an output port of a vacuum pump through a first vacuum pipe, a second evacuation port of the water tank is connected with one end of the second vacuum pipe, and the water tank is in a sealed structure. The vacuum pelletizing port return prevention device is characterized in that the other end of the second vacuum pipe is threaded to a first evacuation port of a return collection tank, one end of a third vacuum pipe is threaded to a second evacuation port of the return collection tank, the other end of the third vacuum pipe is connected with a vacuum port of the double-screw extruder, and the return collection tank is disposed outside the casing of the double-screw extruder. The vacuum pelletizing port return prevention device is capable of preventing return materials from entering the water tank, and facilitates clearing of the return materials.
Description
Technical field
The utility model relates to a kind of anti-material-returning device of granulation vacuum port of double screw extruder.
Background technology
The granulation vacuum port of existing double screw extruder is prevented material-returning device as shown in Figure 1, and tank is built in the extruder housing, and the tank cleaning after the returning charge is very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-material-returning device of granulation vacuum port of double screw extruder, and this device can prevent that returning charge from entering tank, and the returning charge cleaning is convenient.
To achieve these goals, technical scheme that the utility model adopts is: the granulation vacuum port of double screw extruder is prevented material-returning device, it comprises tank, tank is positioned at the housing of double screw extruder, first vacuum orifice of tank is connected with the delivery outlet of vavuum pump by first vacuum tube, second vacuum orifice of tank is connected with an end of second vacuum tube, and tank is a hermetically-sealed construction; It is characterized in that: the other end of second vacuum tube is threaded with first vacuum orifice of returning charge collecting box, one end of the 3rd vacuum tube is threaded with second vacuum orifice of returning charge collecting box, the other end of the 3rd vacuum tube is connected with the vacuum port of double screw extruder, and the returning charge collecting box is positioned at outside the housing of double screw extruder.
Bottom in the described returning charge collecting box is provided with dividing plate, and dividing plate is between second vacuum orifice of first vacuum orifice of returning charge collecting box and returning charge collecting box.
Bottom in the described returning charge collecting box is provided with the material sensor, and the material sensor is positioned at the below of second vacuum orifice of returning charge collecting box.
The beneficial effects of the utility model are: owing to adopted the returning charge collecting box, returning charge at first enters the returning charge collecting box, has prevented that returning charge from entering tank, can prolong the returning charge time; Owing to adopted the returning charge collecting box to be positioned at outside the housing of double screw extruder, the returning charge cleaning in the returning charge collecting box is convenient, can in time handle.
