Description
Technical field
The present invention relates to electric heater unit, more particularly relates to a kind of explosion-proof electric heater unit, belongs to heating
Device field.
Background technology
Industrially usually use electric heater unit.A kind of existing structure of electric heater unit is at present：Including：Spiral shell
Heating wire, single hole magnesium pipe, contact rod, the conducting rod of rotation, the material of single hole magnesium pipe is magnesia, is set in the centerline of heating wire
There is single hole magnesium pipe, the centerline in the inside of single hole magnesium pipe is provided with contact rod, and contact rod left end passes through conducting rod and heating wire
Left end connection, the gap location between the inner surface of single hole magnesium pipe and the outer surface of contact rod is provided with magnesia powder.Inside is filled out
Single hole magnesium pipe filled with magnesia powder plays insulating effect, single hole magnesium pipe of the inside filled with magnesia powder be avoided that contact rod with
Discharged between heating wire.
When processing electric heater unit, it is necessary to magnesia powder is filled into the inner surface and contact rod of single hole magnesium pipe
Outer surface between gap location；At this moment make heating wire left end and single hole magnesium pipe left end it is upward, the right-hand member of single hole magnesium pipe to
Under, gear powder device is then provided with below single hole magnesium pipe；Then the inner surface to single hole magnesium pipe and contact rod from top to down
Gap location filling magnesia powder between outer surface, at this moment can remain air, the magnesia in single hole magnesium pipe in single hole magnesium pipe
The compactness of powder is low；Then gear powder device is removed, while the magnesia powder in single hole magnesium pipe is fixed in single hole magnesium pipe；Again
It is processed further producing final electric heater unit, air is remained in the single hole magnesium pipe in electric heater unit at this moment.When
When electric heater unit is powered, heating wire produces heat, heats the air in single hole magnesium pipe, air expansion, it may occur that blast, it is uneasy
Entirely；With the heating wire of heat oxidation reaction can occur for the air in single hole magnesium pipe, and heating wire can burn, so electric heater unit
Service life it is short.
The content of the invention
The purpose of the present invention is to overcome the above insufficient, there is provided a kind of explosion-proof electric heater unit, it can blast protection, security
High, service life length.
A kind of explosion-proof electric heater unit, including：Heating wire, single hole magnesium pipe, contact rod, the conducting rod of spiral, single hole magnesium
The material of pipe is magnesia, is provided with single hole magnesium pipe in the centerline of heating wire, the centerline in the inside of single hole magnesium pipe is set
There is a contact rod, contact rod left end connected by the left end of conducting rod and heating wire, in the inner surface and contact rod of single hole magnesium pipe
Gap location between outer surface is provided with magnesia powder；At least one groove is provided with the tube wall of the right-hand member of single hole magnesium pipe, it is described
Groove and single hole magnesium pipe inside connect, and described groove connects single hole magnesium tube outside.
The quantity of described groove is 2, and described groove inside single hole magnesium pipe with connecting, and described groove connects
Single hole magnesium tube outside.
The beneficial effects of the invention are as follows：Due to：At least one groove is provided with the tube wall of the right-hand member of single hole magnesium pipe, it is described
Groove and single hole magnesium pipe inside connect, and described groove connects single hole magnesium tube outside, so：In the processing present invention
When, it is necessary to gap location magnesia powder being filled between the inner surface of single hole magnesium pipe and the outer surface of contact rod；At this moment make
The left end of heating wire and the left end of single hole magnesium pipe are upward, and the right-hand member of single hole magnesium pipe is downward, is then provided with below single hole magnesium pipe
Keep off powder device；Then the gap location between the inner surface to single hole magnesium pipe and the outer surface of contact rod fills magnesia from top to down
Powder, the air in single hole magnesium pipe can be discharged by groove to outside single hole magnesium pipe, and air at this moment will not be remained in single hole magnesium pipe, single
The compactness of magnesia powder in the magnesium pipe of hole is high；Then gear powder device is removed, while is consolidated the magnesia powder in single hole magnesium pipe
It is scheduled in single hole magnesium pipe；Further produce the final present invention；Will not in single hole magnesium pipe in the final present invention
Remain air.After the present invention is powered, heating wire produces heat, will not explode, very safe；Because in the present invention
There is no air in single hole magnesium pipe, oxidation reaction does not occur for hot heating wire, and heating wire will not burn, so the present invention's makes
Use long lifespan.
In summary, the present invention can blast protection, safe, service life length.

Embodiment
Described in detail below in conjunction with the accompanying drawings.
A kind of explosion-proof electric heater unit, including：Heating wire 1, single hole magnesium pipe 2, contact rod 3, the conducting rod 4 of spiral, it is single
The material of hole magnesium pipe 2 is magnesia, single hole magnesium pipe 2 is provided with the centerline of heating wire 1, in the inside of single hole magnesium pipe 2
Contact rod 3 is provided with heart line, the left end of contact rod 3 is connected by conducting rod 4 with the left end of heating wire 1, in the interior table of single hole magnesium pipe 2
Gap location between face and the outer surface of contact rod 3 is provided with magnesia powder 6；It is provided with extremely on the tube wall of the right-hand member of single hole magnesium pipe 2
A few groove, described groove connect with the inside of single hole magnesium pipe 2, and the outside of described groove connection single hole magnesium pipe 2.
Can be provided with 2 grooves 5 on the tube wall of the right-hand member of single hole magnesium pipe 2, described groove 5 with inside single hole magnesium pipe 2
Connection, and the outside of described groove 5 connection single hole magnesium pipe 2.
The beneficial effects of the invention are as follows：Due to：2 grooves 5 are provided with the tube wall of the right-hand member of single hole magnesium pipe 2, it is described
Groove 5 connects with the inside of single hole magnesium pipe 2, and the outside of described groove 5 connection single hole magnesium pipe 2, so：Processing this hair
When bright, it is necessary to gap location magnesia powder 6 being filled between the inner surface of single hole magnesium pipe 2 and the outer surface of contact rod 3；This
When make heating wire 1 left end and single hole magnesium pipe 2 left end it is upward, the right-hand member of single hole magnesium pipe 2 is downward, then in single hole magnesium pipe 2
Gear powder device is arranged below；Then the gap location between the inner surface to single hole magnesium pipe 2 and the outer surface of contact rod 3 from top to down
Magnesia powder 6 is filled, the air in single hole magnesium pipe 2 can discharge by 2 grooves 5 to outside single hole magnesium pipe 2, at this moment single hole magnesium pipe 2
Interior to remain air, the compactness of the magnesia powder 6 in single hole magnesium pipe 2 is high；Then gear powder device is removed, while makes single hole
Magnesia powder 6 in magnesium pipe 2 is fixed in single hole magnesium pipe 2；Further produce the final present invention；Final sheet
Air will not be remained in single hole magnesium pipe 2 in invention.After the present invention is powered, heating wire 1 produces heat, will not occur quick-fried
It is fried, it is very safe；Because not having air in the single hole magnesium pipe 2 in the present invention, oxidation reaction, and electricity do not occur for hot heating wire 1
Heated filament 1 will not burn, so the service life length of the present invention.
In summary, the present invention can blast protection, safe, service life length.
