Abstract
The utility model relates to the technical field of electric heater, in particular to an electric heater of a double screw extruder. A positive electrode and a negative electrode are installed on one heating component of the electric heater of a double screw extruder, a positive electrode and a negative electrode are also installed on the other heating component thereof, and the two heating components are semicircular. The electric heater of a double screw extruder comprises two semicircles capable of completely wrapping a screw; when heating, the screw can be quickly heated to be working temperature; when assembling, such semicircles can be conveniently and quickly assembled; and two heating components are installed, thereby avoiding damaging due to overhigh temperature when working again, and saving production cost since just one thereof is to be replaced even if damaged.
Description
Technical field
The utility model relates to the electric heater technical field, especially a kind of electric heater of double screw extruder.
Background technology
Nowadays the electric heater in double screw extruder can't be heated to screw rod suitable working temperature fast in to the extruder screw heating, and the assembling trouble, and after working for a long time, electric heater damages easily.
The utility model content
Can't be rapidly heated in order to overcome the conventional electric heating device, the deficiency of assembling trouble, the utility model provides a kind of electric heater of double screw extruder.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric heater of double screw extruder, on heater block, be provided with positive electrode and negative electrode, also be provided with positive electrode and negative electrode on another heater block, two heater blocks are two semi-circular shapes.
The beneficial effects of the utility model are, the electric heater of this double screw extruder is by two semicircle compositions, can completely screw rod be wrapped up, in heating, can fast screw rod be heated to working temperature, in assembling time,, so two semicircles designs can conveniently assemble, and heater block is double, damaged owing to temperature is too high when having avoided working again, also only need to replace one of them even damaged, saved production cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model;
Among the figure 1, heater block, 2, heater block, 3, positive electrode, 4, negative electrode, 5, positive electrode, 6, negative electrode.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1 is schematic diagram of the present utility model, is provided with positive electrode 3 and negative electrode 4 on heater block 1, and described heater block 2 is provided with positive electrode 5 and negative electrode 6, and heater block 1 and heater block 2 are two semi-circular shapes.
The electric heater of this double screw extruder separates the heater block of two semicircles when installing, and is enclosed within then on the screw rod, and is easy for installation, and then connects with the mains on positive and negative electrode respectively, makes heating quicker, also prolonged the useful life of product.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
