Abstract
The utility model relates to a heating appliance for a galvanized furnace. The shape of the heating appliance is tabular, a resistance wire (1) is vertically wounded through a pylome of a tabular insulating ceramic rack (2), the tabular insulating ceramic rack (2) is supported by a metal frame (3), a lead stick (5) for connecting the two ends of the resistance wire (1) is sleeved by a steel pipe coat (6), an insulating layer (4) is arranged between the steel pipe coat (6) and the lead stick (5), and the steel pipe coat (6) is fixed with the metal frame (3). The utility model is of simple structure and convenient installation and repair, and can be separately arranged between the galvanized furnace and a heat preserving wall.
Description
Technical field
The utility model relates to a kind of electric heater, particularly a kind of electric heater that uses on galvanizing furnace.
Background technology
Electroheat equipment is because production instructions for use difference, of a great variety, the electric heating equipment that uses on galvanizing furnace is a part wherein, because the continuous production operation cycle of galvanizing furnace is long, consumed power is big, the electric heating equipment is damaged easily, and therefore the electric heater that uses on galvanizing furnace will accomplish that generally energy-conservation, the while can timely remover apparatus fault.And present known electric heater is to adopt resistance wire or resistive band, after coiling is shaped, with heat-insulation layer is to be connected as a single entity, maintenance was inconvenient when this electric heater broke down, and its thermo electric material and heat-insulation layer and outer cover of steel plate, lead-in wire rod are to form an integral body by in the horizontal direction embedding galvanizing furnace outside framework when installing, and between every block of electric hot plate long seam is arranged, internal-external temperature difference causes many thermal loss greatly easily.
Also there is the minority galvanizing furnace to adopt the form that on underground space for collecting ashes in a stove inwall, embeds thermo electric material to heat, this structure is when thermo electric material damages, can only from the maintenance groove that two ends are reserved, change, distance, operation easier is bigger, be easy to generate wrong the placement and cause that heating wire exposes, short circuit, hidden danger such as easily broken.
The utility model content
Technical problem to be solved in the utility model provides a kind of easy installation, overhauls galvanizing furnace electric heater easily.
The utility model solves the problems of the technologies described above with following technical scheme: the profile of electric heater is tabular, the resistance silk ribbon is vertically worn in the through hole of tabular insulating ceramics frame, the insulating ceramics frame is supported by metal framework, be with the steel pipe overcoat on the lead-in wire rod at connection resistance silk ribbon two ends, between steel pipe overcoat and the lead-in wire rod insulating barrier is arranged, the steel pipe overcoat is fixed on the metal framework.
The lead-in wire rod that connects resistance silk ribbon two ends also can be replaced by resistant to elevated temperatures insulated conductor.
Electric heater of the present utility model is simple in structure, can be arranged separately between zinc pot and the insulated wall, installs, maintenance is all very convenient.
Description of drawings
Fig. 1 is the structural representation of a kind of electric heater that uses on galvanizing furnace of the utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the profile of the utility model electric heater is tabular, resistance silk ribbon 1 is vertically worn in the through hole of the tabular insulating ceramics frame 2 that is made of many bar insulations pottery transverse slats 8 and two ceramic legs 7, insulating ceramics frame 2 is supported by metal framework 3, be with steel pipe overcoat 6 on the lead-in wire rod 5 at connection resistance silk ribbon 1 two ends, between steel pipe overcoat 6 and the lead-in wire rod 5 insulating barrier 4 is arranged, the steel pipe overcoat is fixed on the metal framework 3.
When in galvanizing furnace, using the utility model, can adopt the mode of vertical insertion to be installed between zinc pot and the heat-insulation layer, during maintenance, need not to destroy the heat-insulation layer of zinc pot periphery, only need the heat-insulation layer on pot top is taken off, just electric heater can be taken out and change or keep in repair, thereby the maintenance that had both guaranteed galvanizing furnace does not stop production, and does not influence heat insulation effect again.The lead-in wire rod is installed in electric heater top, can lead to normal temperature zone, outside from the insulated wall top and connect power supply.
Insulating barrier 4 can be by irritating towards powder insulation material between steel pipe overcoat and the lead-in wire rod, and through high pressure-temperature curing and make.
The lead-in wire mode of the utility model electric heater also can be to adopt the insulated conductor of high temperature resistant (more than 700 ℃) to be drawn out to the normal temperature district by the mode that is flexible coupling in stove.
Claims (2)
1. electric heater that on galvanizing furnace, uses, include resistance silk ribbon (1), lead-in wire rod (5), it is characterized in that: the profile of this electric heater is tabular, resistance silk ribbon (1) is vertically worn in the through hole of tabular insulating ceramics frame (2), insulating ceramics frame (2) is supported by metal framework (3), the lead-in wire rod (5) that connects resistance silk ribbon (1) two ends is with steel pipe overcoat (6), between steel pipe overcoat (6) and the lead-in wire rod (5) insulating barrier (4) is arranged, steel pipe overcoat (6) is fixed on the metal framework (3).
2. the electric heater that uses on galvanizing furnace according to claim 1 is characterized in that: the lead-in wire rod that connects resistance silk ribbon two ends is replaced by resistant to elevated temperatures insulated conductor.
