Description
Technical field
The present utility model is related to a kind of electric heater, and especially one kind is in equipment manufacturing field to workpiece or mold
The electric heater heated.
Background technique
In equipment manufacturing field, workpiece or mold are heated sometimes in production process, heating tool generallys use
Electric heater.Traditional electric heater is mostly unistage type heating, and inside only has one group of resistive heater, and working method is quota work
Make, non-stop run and temperature can not be adjusted.Such electric heater has many disadvantages, for example, various sizes of workpiece or
And mold, every time in use, the contact area size of workpiece or mold and electric heater all can be different；When workpiece or mold
Greater than electric heater size when, workpiece or mold have portion cannot directly add because that cannot contact with electric heater
Heat causes heating rate slower, and efficiency is lower；When workpiece or mold are less than the size of electric heater, electric heater has part
Position cannot be contacted with workpiece or mold, this part self heat transmit outward it is limited, the heat of accumulation cause itself heat up
Fast speed keeps ultra-high temperature for a long time, does not only result in energy waste, can also seriously affect the service life of electric heater.
Summary of the invention
The purpose of this utility model is that being directed to the drawbacks described above of existing electric heater, proposing a kind of multistage heating and can dividing
Not Jian Kong temperature electric heater, improve heating efficiency, and can prolong the service life.
The technical solution of the utility model is as follows:
A kind of multistage heating can monitor the electric heater of temperature, including electric heating wire shell respectively, be equipped with electricity in shell and add
Heated filament, it is characterised in that: the electric heating wire has at least 3 sections, does not overlap between each section, and first segment electric heating wire is from shell
Front end start setting up, the rear end of second segment electric heating wire from first segment electric heating wire starts setting up, remaining electric heating wire press this
Mode is set gradually；Each section of electric heating wire individually connects external power supply；Each section of electric heating wire setting is a set of to be separately monitored the section
The thermocouple of electric heating wire temperature；Gap and each section of gap between electric heating wire and shell between each section of electric heating wire
Fill thermostable heat-conductive material.
Multistage resistance wire is arranged in the utility model in electric heater, can individually heat and can be controlled respectively to every section of resistance wire
Each section of temperature is made, it can be by the larger of the size design of electric heater, for various sizes of workpiece or mold, as needed
The power supply of an appropriate number of resistance wire is connected, the energy can be saved, improved efficiency, and the service life of electric heater can be extended.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model includes electric heating wire shell 1, electric heating wire 2 is equipped in shell 1；The electric heating
Silk 2 has at least 3 sections, does not overlap between each section, and first segment electric heating wire is started setting up from the front end of shell, second segment electricity adds
The rear end of heated filament from first segment electric heating wire starts setting up, remaining electric heating wire is set gradually in this way；Each section of electric heating wire
Individually connection external power supply.
Further, it is the real time temperature for monitoring electric heating wire, is convenient for temperature control, each section of electric heating wire 2 is set
Set a set of thermocouple 4 for being separately monitored this section of electric heating wire temperature.
High temperature resistant stainless steel material can be used in rotatable heater housing, the gap between each section of electric heating wire 2 and each section
The thermostable heat-conductives such as magnesia or aluminium oxide ceramics material 3 is filled in gap between electric heating wire 2 and shell 1.
The utility model is when it is implemented, the length of every section of electric heating wire adds small workpiece or mold generally in 15-20cm
One section is only connected when hot；The entire length of electric heater heating part is then heated workpiece or mold according to usually maximum
Setting, the quantity of electric heating wire are then arranged according to the entire length of electric heater heating part, can set 3-5 sections, or more, with full
Heating of the foot to large scale tool or mold；Above structure can save the energy under the premise of guaranteeing heating efficiency.
