Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater hanger for a heater mounted on a side wall of a ceramic fiber of an electric furnace.

[0002]

2. Description of the Related Art Conventionally, in order to mount a heater on a side wall of a ceramic fiber, an insulating stud bolt whose middle is electrically insulated is welded mainly to an outer steel plate, and a spinning wheel-shaped insulator is attached to the tip of the stud bolt. Attachment, the belt-shaped heater is corrugated and attached.

[0003]

However, in this case, a large number of insulating stud bolts must be fixed to the steel plate before the ceramic fiber is applied in accordance with all the corrugated pitch dimensions of the heater. It is troublesome and inconvenient. If it is necessary to add an insulating stud bolt due to a difference in the number of heater pitches, the ceramic fiber must be peeled off and the additional insulating stud bolt must be attached. If the heater is large or the temperature is high, the insulating stud bolt will bend downward. A heater hanger that does not require such effort, can easily add the number of pitches, can freely change the pitch size, and does not bend the insulating stud bolt even if the heater is large and heavy, even if the temperature is high Desired.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, a fixed heater hanger of the present invention is a material having good electrical insulation at high temperatures, high heat resistance, and fixed height dimensions. .

This fixed type heater hanger has a pedestal at the bottom of a column, a cylindrical heater receiving portion with a stopper on the upper portion, a load receiving portion, a holding board receiving portion, and a plurality of receiving portions on a rear surface. It has sharp projections.

[0006] In an electric furnace in which ceramic fiber is lined inside a well-known steel plate box, a plurality of heat-resistant steel stud bolts for attaching a heat insulating material, a ceramic fiber board, and the like are welded to an inner side wall.

A side wall heat insulating material is lined on the side wall, a side wall board made of ceramic fiber is put on the side wall, and a rectangular receiving board made of ceramic fiber at the lowermost portion is attached by piercing stud bolts.

[0008] A fixed-type heater hanger corresponding to the number of wave pitches of the heater is mounted on the receiving board.

A corrugated heater is attached to the fixed heater hanger, and a holding board is attached with a washer and a nut so that the fixed heater hanger does not come forward from above.

In the case of the adjustable heater hanger, the upper part has the same structure as that of the fixed heater hanger. However, in order to adjust the height of the heater according to the wave height of the heater, a female screw is cut in the lower part and the lower part is cut there. Is a screw-shaped disk-shaped adjustment bolt, and the adjustment bolt is turned in the opposite direction to make the whole longer, so that the receiving board can be firmly supported.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to the drawings. In FIGS. 3, 4, 5 and 6, this is a fixed type heater hanger A. A cylindrical heater receiving portion 10 having a stopper 12 is provided on an upper portion thereof, and a load receiver 9 and a holding board receiver 15 are mounted on the upper portion thereof.
A plurality of projections 14 having sharp tips are attached to the back surface of the device to complete the process.

FIG. 1 and FIG. 2 are assembly configuration diagrams of a heater 2 using a heater hanger A. Stud bolts are welded to the steel plate 7 at the design dimensions, and there is a side wall insulation material 8
Is attached, a side wall board 5 is stretched thereon, and a plurality of receiving boards 4 processed into strip-shaped design dimensions are inserted on stud bolts, leaving a space corresponding to the height of the fixed type heater hanger A, A fixed type heater hanger A having the number of wave pitches of the heater is fitted between the receiving boards 4, the corrugated heater 2 is set therein, and the projection 14 having a sharp tip is pushed into the side wall board 5, and the fixed type heater hanger A is The pedestal 11 is covered so as not to protrude, and the pedestal 11 is placed on the holding board receiver 15, and the holding board 6 is fixed with stud bolts, washers and nuts 3 so as to hold the load receiver 9.

7, 8, and 9, this is an adjustable heater hanger B. A cylindrical heater receiving portion 10 having a stopper 12, like the fixed heater hanger A, is provided above the adjustable female screw 16. A load receiver 9 and a holding board receiver 15 are provided on the upper part, a plurality of projections 14 having a sharp tip are mounted on the back surface thereof, and an adjusting bolt 17 having a disk shape at one end is screwed into an adjusting female screw 16 to be set and completed. However, the disk of the adjusting bolt 17 needs to be smaller than the thickness of the receiving board 4.

FIG. 10 and FIG. 11 are assembly configuration diagrams of the heater 2 using the adjustable heater hanger B.
As in the case of the fixed heater hanger A, a stud bolt is welded to the steel plate 7 at a design dimension position, a side wall heat insulating material 8 is stuck thereon, a side wall board 5 is stretched thereon, and a strip-shaped design is formed thereon. A plurality of receiving boards 4 processed to dimensions
The adjustable heater hanger B is inserted into the stud bolt with a predetermined height dimension of the adjustable heater hanger B, and the adjustable heater hanger B between the receiving boards 4 has the number of heater wave pitches.
And a wave-shaped heater 2 is set therein. Next, turn the disk of the adjustment bolt 17 in reverse so that it becomes longer,
Push the receiving board 4 firmly, push the pointed projection 14 into the side wall board 5, and cover the disc portion of the adjusting bolt 17 so that the adjustable heater hanger B does not come forward. The holder board 6 is fixed on the holding board 6 with stud bolts, washers, and nuts 3 so as to ride on the load holder 15 and hold the load receiver 9.

[0015]

Since the present invention is configured as described above, it has the following effects.

According to the wave pitch dimension of the heater, it is not necessary to fix and mount a large number of insulating stud bolts corresponding to the wave number to the steel plate on the side wall of the furnace body.

There is no bending of the insulating stud bolt even if the heater is large and heavy or the temperature is high.

Even if there is a difference between the number of heater hangers and the number of heater waves, there is no need to peel off the ceramic fiber and weld the insulating stud bolt to the furnace steel plate.
Just add a heater hanger and fit it.

The fixed type or the adjustable type can be manufactured at a low cost because the number of manufacturing steps is small.

Since this heater hanger is not fixed on the outer wall of the furnace, the electrical insulation is complete.

In the adjustable heater hanger, the height can be changed in accordance with the wave height of the heater, which is convenient.

With such a simple configuration, the mounting can be easily performed by an amateur.
