Description
Technical field
The utility model relates to electric heating tube technical field, particularly relates to a kind of single head U-tube and straight-bar is removable
Type electric heating tube.
Background technique
Currently, most of straight-bar in the prior art uses king bolt silk, central electrode silk need to be logical inside taenidium
It crosses, current structure electric clearance is small, for a long time using the open circuit that will lead to taenidium Yu central electrode silk, so that electricity adds
Thermotube wall bursts, extremely dangerous, to improve working efficiency and improving the practicability of electric heating tube, extends heating tube
Service life reduces risk, and the utility model proposes a kind of single head U-tube and straight-bar knockdown type electric heating tubes.
Utility model content
Technical problem to be solved in the utility model is, the shortcomings that for the above prior art, proposes that a kind of single head is U-shaped
Pipe and straight-bar knockdown type electric heating tube, improve heating efficiency, extend service life, also, structure is simple, easy to maintain.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is achieved in the following ways：A kind of list
Head U-tube and straight-bar knockdown type electric heating tube, including bottom end seal, top are equipped with high temperature porcelain head, different in size and connect side by side
Two metal steel pipes, the top of high temperature porcelain head is also connected with equipped with binding post, is built-in with U-shaped single hole oxygen in the tube body of metal steel pipe
Change magnesium pipe, U-shaped single hole magnesia tube is extended from the one third inside metal steel pipe to bottom, U-shaped single hole magnesia
The both ends of pipe are provided with the diplopore magnesia tube to match therewith, and diplopore magnesia tube is coated on U-shaped single hole magnesia tube and sets
It sets and is equipped with resistance wire in U-shaped single hole magnesia tube.
The technical solution that the utility model further limits is：
Single head U-tube above-mentioned and straight-bar knockdown type electric heating tube, the gap location of U-shaped single hole magnesia tube and metal steel pipe
Filled with magnesia bisque.
Single head U-tube above-mentioned and straight-bar knockdown type electric heating tube, metal steel pipe are equipped with sealing pressure at high temperature porcelain head
Block.
The utility model has the beneficial effects that：By the technical solution of the utility model, which is aoxidized using U-shaped single hole
Magnesium pipe, electric furnace heating wire are fixed by U-shaped single hole magnesium pipe, and the diplopore magnesia tube by being coated on U-shaped single hole magnesium pipe is reinforced, Neng Goubao
It is fixed placed in the middle in steel pipe to demonstrate,prove electric furnace heating wire, it is ensured that the electric clearance of the maximum safety of product reduces surface loading, improves hair
The thermal efficiency extends the service life of electric heating tube.The electric heating tube also uses the connection type of fastener sealed briquette, can appoint
Anticipate withdrawing disassembly, be convenient for changing, and the single head U-tube and straight-bar knockdown type electric heating tube structural principle it is simple, Operation and Maintenance
It is convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein：1- high temperature porcelain head, 2- metal steel pipe, 3- binding post, 4-U shape single hole magnesia tube, 5- diplopore magnesia tube,
6- resistance wire, 7- magnesia bisque, 8- sealed briquette.
Specific embodiment
The utility model is described in further detail below：
Embodiment 1
A kind of single head U-tube provided in this embodiment and straight-bar knockdown type electric heating tube, including bottom end seal, top are equipped with
High temperature porcelain head 1, different in size and two metal steel pipes 2 connecting side by side, metal steel pipe 2 are equipped with sealing at high temperature porcelain head 1
Briquetting 8, the top of high temperature porcelain head 1 are also connected with equipped with binding post 3, are built-in with U-shaped single hole magnesia tube in the tube body of metal steel pipe 2
4, U-shaped single hole magnesia tube 4 is extended at the one third from inside metal steel pipe 2 to bottom, U-shaped single hole magnesia tube 4
It is filled with magnesia bisque 7 with the gap location of metal steel pipe 2, the both ends of U-shaped single hole magnesia tube 4 are provided with to match therewith
Diplopore magnesia tube 5, diplopore magnesia tube 5 be coated on U-shaped single hole magnesia tube 4 setting and 4 middle berth of U-shaped single hole magnesia tube
Equipped with resistance wire 6.
By the technical solution of the utility model, which uses U-shaped single hole magnesia tube, and electric furnace heating wire is by U-shaped single hole magnesium
Pipe is fixed, and the diplopore magnesia tube by being coated on U-shaped single hole magnesium pipe is reinforced, and can be guaranteed that electric furnace heating wire is fixed in steel pipe and be occupied
In, it is ensured that the electric clearance of the maximum safety of product reduces surface loading, improves heating efficiency, extends electric heating tube
Service life.The electric heating tube also uses the connection type of fastener sealed briquette, can arbitrarily dismantle withdrawing, be convenient for changing,
And the single head U-tube and straight-bar knockdown type electric heating tube structural principle is simple, convenient operating maintenance.
Above embodiments are only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within the scope of novel protected.
