Description
Technical field
The utility model relates to the plastic extruder heater, particularly a kind of plastic extruder high efficiency energy saving heater.
Background technology
At present, in the machine barrel outside of plastic extruder heater is installed all, the plastics in the machine barrel are heated, make it to heat up, to reach the needed temperature of technological operation.Existing heater in use all exists certain not enough, as: stainless steel mica sheet resistor-type backing, its heat resistance is not good, in case not good will overheatedly the burning of contact, reliability is general, and thermal diffusivity is bad, the efficiency of heating surface is low; The resistor-type ceramic heater, the efficiency of heating surface is lower; Electromagnetic induction additivity device thermal diffusivity is bad, and reliability is not good; Use comparatively general pre-buried resistor-type cast aluminium heating, exist the efficiency of heating surface low, the problem that heat waste is high.And, owing in the production process, also needing cooling device to guarantee that plastics are in the temperature range of technological requirement.But existing heater and cooling device are independent setting, exist and install and use inconvenience, the shortcoming that control accuracy is not good enough.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the plastic extruder high efficiency energy saving heater that provide a kind of compact conformation, be convenient to install, the efficiency of heating surface is high, energy consumption is low, accuracy of temperature control is good.
The utility model solves its technical problem and realizes by the following technical solutions:
A kind of plastic extruder high efficiency energy saving heater, it is characterized in that: comprise dressing up the two halves formula heating component of tubular, this two halves formula heating component includes shell, heat shield and heater, section's mounting heater in the enclosure, between shell and heater, heat shield is installed, be shaped with heat exchange in a radially end of shell and exchange the chamber, exchange chamber in this heat exchange blower fan is installed, be shaped with exhaust outlet at the radially other end of shell.
And described heat shield is the foamed heat insulating heat shield.
And, be shaped with in the axial two ends of shell outer surface symmetry and fixedly use dop.
And described blower fan and heater all are connected to controller.
Advantage of the present utility model and beneficial effect are:
1. this plastic extruder high efficiency energy saving heater, heater is set in housing cooling blower is set simultaneously, realize the integrated application of heating technique, hot swapping, promote to greatest extent the heater heat exchanger effectiveness, make heating object reach the soonest the setting operating mode, effectively reduce energy consumption, improving heater can be handling.
2. this plastic extruder high efficiency energy saving heater adopts the foamed heat insulating heat shield, plays good thermal insulation function, effectively reduces heat waste, further reduces energy consumption.
3. this plastic extruder high efficiency energy saving heater, adopt automatic control technology, can be according to the standardized control panel of actual applying working condition design, can be according to 3-6 heater of operating mode needs control, realize that controller and heater, controller are connected with standard between the equipment control subject, have splendid technological temperature control accuracy and stable.
4. the utility model compact conformation, design science is reasonable, and the efficiency of heating surface is high, energy consumption is low, accuracy of temperature control is good, and good looking appearance, easy to install, be convenient to packed and transported, be a kind of heater for plastics extruder with higher innovation, have good popularizing application prospect.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of plastic extruder high efficiency energy saving heater, it is by the two halves formula heating component of dressing up tubular is consisted of, this two halves formula heating component consists of by shell 1, heat shield 3 and heater 4, section's mounting heater in the enclosure, between shell and heater heat shield is installed, heat shield is the foamed heat insulating heat shield.Be shaped with heat exchange in a radially end of shell and exchange chamber 7, exchange chamber in this heat exchange blower fan 6 is installed, be shaped with exhaust outlet 5 at the radially other end of shell.Be shaped with fixing with dop 2 in the axial both ends of shell symmetry.Blower fan and heater all are connected to the controller (not shown).
Operation principle of the present utility model is:
Adopt the Buckle device symmetry to be fixed on the machine barrel outside by the fixing of its two ends with dop this heater.When starting working, heater provides heat for main, and simultaneously, blower fan is by the low discharge air-flow, so that heater is finished in heat exchange exchanges the chamber fast with the heat exchange of extruder barrel, extruder reaches operating temperature fast.The shelves extruder reaches when setting critical condition, and the temperature sensor feedback temperature value by being contained in extruder barrel is to controller, to extruder barrel, or strengthens the fan work rotating speed by controller control heater additional heat, forces air draft to take away heat.Heat shield is used for promoting the efficiency of heating surface, reduces invalid thermal loss.
This heater is more energy-conservation more than 35% than original resistance-type heater, compares with electromagnetic heater, can provide fault rate close to zero high reliability, and the incomparable heat dispersion of Electromagnetic Heating mode, has splendid technological temperature control accuracy and stability.
