Abstract

The utility model belongs to a resistance band fixing piece for industrial furnaces, which mainly relates to a resistance band fixing device for using on a full fiber furnace wall. The utility model is mainly composed of multiple fixation hooks; one end of a fixation hook 1 is inserted into a fibre furnace wall downward 45-60 DEG, the other end which is used for hanging the resistance band forms an included angle of 135-150 DEG with the fixation hook 1; a porcelain bead 2 is sheathed on the fixation hook 1, which is fixed by a porcelain pad 4 and a pin 3; a big wave shape resistance band 5 which is suspended is fixed to fixation hooks which treat every top and bottom roots as a group. The utility model has the advantages of relative convenient installation, maintenance and replacement; the heat storage loss of the prime shelf bricks is reduced, and heat efficiency is enhanced.

Description

Resistance with fixing device for industrial furnace

The utility model belongs to the resistive band fixture of industrial furnace, relates generally to the resistive band fixture of using on a kind of full fiber wall.

The applicant is to propose the furnace lining that a kind of industrial furnace furled blanket type entire fibre lining gives clamp dog and formation thereof in 92238062.7 the utility model patent " industrial furnace furled blanket type entire fibre lining " in the patent No., to reach energy savings, reduce cost and improve the furnace lining purpose in service life, it mainly utilizes fibrous material to make as furnace wall, the furled blanket type of furnace roof gives clamp dog, and be connected and form the industrial furnace entire fibre lining by giving the clamp dog monoblock, it gives when the compressed fibre furnace wall in order to the shelf brick of placing heating and putting in it, on the shelf brick, place the resistive band of heating wire or small form, but its lifting that is not suitable for the big waveform resistive band of high-power industrial furnace is fixed, and does not still have for big waveform resistive band at present a kind of fixing means and device of lifting preferably arranged.

The purpose of this utility model promptly produces thus, and the device of hanging fixing big waveform resistive band on full fiber furnace wall that it mainly proposes adapting to the needs of high-power industrial furnace, and further improves the thermal efficiency, and is easy to installation and maintenance.

The own characteristic of the full fiber furnace wall of the utility model utilization, it inserts the fiber furnace wall by many one ends, one end bearing is hung the stay hook of resistive band and is formed, the stay hook of metal material is in order to the supporting part of hanging the fixed resistance band and to insert between the fiber furnace wall part be 135～150 ° of angles, insert the firm relatively of assurance stay hook for oblique 45～60 ° so that insert the furnace wall part, and make the supporting part outside furnace wall vertical with body of wall, two stay hooks are one group and resistive band are hung fixing up and down, form one of them waveform of big waveform resistive band, a plurality of stay hooks are formed resistive band fixture of the present utility model.

Use of the present utility model is to treat that full fiber furnace wall installs, the direction downward 45～60 ° in the upper edge, position of needs inserted stay hook, guarantee to be difficult for withdrawing from voluntarily when the stay hook along continuous straight runs is stressed, the unit weight that its feasibility is based on when furled blanket type refractory fibre furnace wall reaches 250Kg/m ³Its intensity is enough to bear stay hook and the weight of the resistive band of being born when above, furnace wall is inserted for oblique 45～60 ° in the stay hook lower end, the upper end that becomes 135～150 ° of angles with the lower end is that the resistive band supporting part is vertical with body of wall, with the porcelain bead cover thereon, fix with ceramic gasket and pin, big waveform resistive band is hung on it, by up and down two be one of them waveform that one group stay hook is finished big waveform resistive band.

The big waveform resistive band fixture that the utility model proposes, the resistive band that is suitable for the full fiber furnace wall of high-power industrial furnace is hung fixing, its advantage shows as highlightedly: installation, maintenance, change comparatively convenient, reduced the accumulation of heat loss of former shelf brick, shorten the empty stove heating-up time, improved the thermal efficiency.

The utility model provides the following drawings:

Accompanying drawing 1 is the utility model stay hook structural representation.

Accompanying drawing 2 is the utility model user mode schematic diagram.

Accompanying drawing 3 is Fig. 2 side view.

As shown in drawings, the utility model stay hook 1 by an end insert the fiber furnace wall and and between it angle be that 135～150 ° the other end promptly supports the supporting part of hanging resistive band and forms, it can adopt the wire of Cr18NiSi2 to manufacture, during use with the lower end with in 45～60 ° of oblique insertion fiber furnace walls 6, its other end promptly forms vertical with furnace wall, porcelain bead 2 covers thereon, with porcelain pad 4 and pin 3 porcelain bead is fixed, can insert the perforate of pin part at stay hook, so that pin passes, its up and down two stay hooks 1 be one group and hang one of them waveform that resistive band forms big waveform resistive band, total some groups of stay hooks are fixing in order to finish hanging of big waveform resistive band on the industrial furnace fiber furnace wall 6, and promptly the utility model is made up of many stay hooks 1.

Claims

1, a kind of industrial furnace resistive band fixture, mainly be applicable to the fixing big waveform resistive band of lifting on the full fiber furnace wall, of the present utility modelly be characterised in that it is made up of many stay hooks (1), between insertion furnace wall one end of stay hook (1) and the other end in order to the lifting resistive band is 135～150 ° of angles, stay hook (1) one end inserts in the fiber furnace wall (6) for downward 45～60 °, the other end is vertical with body of wall, porcelain bead (2) cover thereon, fixing with porcelain pad (4) and pin (6), big waveform resistive band (5) lifting be fixed on every up and down two be on one group the stay hook.
