The electromagnetic heating devices are uniformly distributed on the circumference of the plastic machine charging cylinder; the electromagnetic heating device further comprises a charging cylinder temperature reducing device and a cooling pipeline wound around the circumference of the plastic machine charging cylinder; the charging cylinder temperature reducing device is used for reducing the temperature of the plastic machine charging cylinder; the water inlet end of the cooling pipeline is connected with a solenoid valve; when the temperature detected by a system is higher than that predetermined, the solenoid valve is opened to supply water for the cooling pipeline. The utility model can reduce the effect of abnormal temperature rise on the quality of the products, improves the quality of the products, and simultaneously achieves the purposes of saving the energy and optimizing the operating environment.
Description
Technical field
The utility model relates to electromagnetic heater, relates in particular to a kind of plastic cement machine electromagnetic heater.
Background technology
At present, the plastic products industry uses far infrared Electric heating and electromagnetism mode of heating to heat as the plastic cement machine.But because the far infrared electric heater unit is a kind of mode of heating of resistance heat, its heating efficiency is lower, and each big businessman all uses the electromagnetism mode of heating to heat as the plastic cement machine basically now.A kind of is the Chinese patent 01114569.2 of plastic cement machine heating with the electromagnetism mode of heating, it is a kind of screw extrusion equipment electromagnetic heater, comprise extruder screw, plastic cement machine barrel, loading hopper, support, heater, heater is an electromagnetic heater, this device is made of the electromagnetism heating component, be arranged in the periphery of plastic cement machine barrel equably, and the many rows that are more than at least one row along the axis of plastic cement machine barrel arrange, the magnetic line of force of electromagnetism heating component directly acts on around the barrel, and forms numerous vortex shape induced-current in barrel.But unusual the intensification appears in material such as some engineering material such as PC, polymethyl methacrylate easily when heating, thereby reduces product quality.
The utility model content
The utility model provides a kind of plastic cement machine electromagnetic heater at the above-mentioned defective of prior art, to tackle unusual intensification, improves product quality, reaches energy-conservation simultaneously and the optimization operating environment.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of plastic cement machine electromagnetic heater, comprise screw rod, plastic cement machine barrel, electromagnetic heater, described electromagnetic heater is uniformly distributed in around the plastic cement machine barrel, also comprise the barrel heat sink, be wound in the cooling pipe of plastic cement machine barrel periphery, the barrel heat sink is used to reduce the temperature of plastic cement machine barrel, and the cooling pipe water inlet end is connected to magnetic valve; The control magnetic valve is opened when system detects temperature and is higher than default temperature, supplies water to cooling pipe.
Preferably, also comprise the heat insulation foam of one deck between described cooling pipe and the electromagnetic heater, described heat insulation foam is wrapped up on described cooling pipe.
Preferably, described magnetic valve is provided with thrift lock, is used for the difference regulating pondage according to detected temperature of system and preset temperature.
Preferably, described cooling pipe is metallic articles such as aluminum or copper.
As can be seen from the above technical solutions, the utility model installs cooling pipe additional around plastic cement machine barrel, when unusual the intensification occurring, injecting water to cooling pipe cools off plastic cement machine barrel, reduce unusual the intensification to the influence of product quality, improve the quality of product, reach energy-conservation simultaneously and the optimization operating environment.。
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
Shown in accompanying drawing, the utility model comprises screw rod 1, plastic cement machine barrel 2, cooling pipe 3, electromagnetic heater 5, and cooling pipe 3 is wound in the periphery of plastic cement machine barrel 2, and cooling pipe 3 water inlet ends are connected to magnetic valve; The utility model also comprises the barrel heat sink, and this device is used to reduce the temperature of plastic cement machine barrel 2; When the detected temperature of system was higher than default temperature, the control magnetic valve was opened, and supplies water to cooling pipe.
As preferred implementation of the present utility model, also comprise the heat insulation foam 4 of one deck between described cooling pipe 3 and the electromagnetic heater 5, described heat insulation foam 4 is wrapped up on described cooling pipe 3.
As preferred implementation of the present utility model, described electromagnetism thrift lock is provided with thrift lock, is used for the difference regulating pondage according to detected temperature and preset temperature.
Because electromagnetic heater can act on iron compound and warmly producing, so the utility model cooling pipe adopts metallic articles such as higher aluminum of the coefficient of heat conduction or copper.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
