Description
Technical field
The utility model belongs to radiant type electric heating belt reduction furnace equipment, is specifically related to a kind of radiant type electric heater.
Background technology
Radiant type electric heating belt reduction furnace is the high production reduced iron powder belt reduction furnace of introducing from the U.S. of production technology advanced person, automaticity, and the radiant type electric heater is exactly a kind of being used for this belt reduction furnace to be carried out the device that radiation is heated.Existing radiant type electric heater comprises the hard radiant tube of one one end sealing, be placed with the discoid bone support that several are arranged vertically in the radiant tube, the middle part of bone support one side is provided with a horn-like projection, and this horn-like projection can separate adjacent two bone supports.Offer on each bone support and add the annex through hole, these annex through holes are that the center is concentric circles and distributes with the central shaft of bone support.Electrical heating wire inserts controllable power by conductive contact after twining the annex through hole that passes the bone support.In producing the iron powder reducing process, the belt reduction furnace keeps furnace temperature about 900～960 ℃ of scopes according to the belt speed different needs.Because the radiant type electric heater is worked under hot environment for a long time, the radiant type electric heater is lowered the temperature rapidly after running into artificial blowing out or unexpected the power failure in the course of work, electrical heating wire, conductive contact and be subjected to big difference variation and cause torsional deformation easily by the skeleton body that several bone holder combination form, touch the radiant tube body easily after the electrical heating wire distortion of cross-under in skeleton body and cause the discharge tripping operation, also can cause to bump to connect between two conductive contacts of connection electrical heating wire and power supply and cause the short circuit tripping operation because of distortion, these tripping operations can cause outage and cause the furnace temperature shakiness, production technology is affected, and bad change takes place in product quality.
Summary of the invention
The purpose of this utility model is exactly will provide a kind of skeleton body and conductive contact is fixed, furnace temperature is stable, can effectively avoid electrical heating wire, conductive contact and skeleton body torsional deformation and cause the radiant type electric heater of discharge tripping operation accident.
For achieving the above object, radiant type electric heater of the present utility model, the hard radiant tube that comprises end sealing, be placed with the discoid bone support that several are arranged vertically in the hard radiant tube, the middle part, the same side of each bone support is provided with horn-like projection, and horn-like projection can separate adjacent two bone supports; Offer the annex hole on each bone support, annex is interspersed with electrical heating wire in the hole, the two ends of electrical heating wire link to each other with conductive contact, conductive contact links to each other with controllable power, described hard radiant tube is provided with the insulation pallet near an end of conductive contact, offer the joint through hole on the described insulation pallet, described conductive contact is installed in the joint through hole; The center of described each bone support offers central shaft hole, is interspersed with the hard central shaft in the described central shaft hole, and described hard central shaft connects as one each bone support serial connection.
Further, be provided with insulating washer between described bone support and the hard radiant tube.Like this, can effectively strengthen the distance between heating element and the radiant tube body, reduce the probability of short circuit between the two.Preferred insulating washer thickness is 10mm.
Further, described insulation pallet center offers the pallet centre bore, and described hard central shaft also passes the pallet centre bore of insulation pallet.Help to strengthen the heat shock resistance holding capacity of conductive contact like this.
The beneficial effects of the utility model are: by near conductive contact one end an insulation pallet being set at hard radiant tube body, described conductive contact is connected with power supply after passing the joint through hole of insulation on the pallet again, can effectively avoid the short circuit that causes because of torsional deformation between two conductive contacts; Simultaneously add a hard central shaft in the central shaft hole of each the bone support on skeleton body, each bone support serial connection is connected as one, can solve the rise sharply heat shock resistance holding capacity of rapid drawdown of skeleton body opposing temperature effectively.Radiant type electric heater of the present utility model can effectively be avoided electrical heating wire, conductive contact and skeleton body torsional deformation and cause discharge tripping operation accident.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Radiant type electric heater shown in the figure, the hard radiant tube 1 that comprises end sealing, be placed with the discoid bone support 2 that several are arranged vertically in the hard radiant tube 1, the middle part, the same side of each bone support 2 is provided with horn-like protruding 12, horn-like protruding 12 and adjacent two bone supports 2 can be separated; Offer annex hole 9 on each bone support 2, be interspersed with electrical heating wire 3 in the annex hole 9, the two ends of electrical heating wire 3 link to each other with conductive contact 5, conductive contact 5 links to each other with controllable power, hard radiant tube 1 is provided with insulation pallet 6 near an end of conductive contact 5, offer joint through hole 10 on the insulation pallet 6, conductive contact 5 is installed in the joint through hole 10; The center of each bone support 2 offers central shaft hole 8, is interspersed with hard central shaft 4 in the central shaft hole 8, and described hard central shaft 4 connects as one each bone support 2 serial connections.Be provided with insulating washer 7 between bone support 2 and the hard radiant tube 1, insulating washer 7 thickness are 10mm; Insulation pallet 6 centers offer pallet centre bore 11, and hard central shaft 4 also passes the pallet centre bore 11 of insulation pallet.
During work,, can effectively avoid the short circuit that causes because of torsional deformation between two conductive contacts 5 because two conductive contacts 5 are connected with power supply after passing insulation pallet 6 top connection through holes 10 again; In the central shaft hole 8 of each bone support 2, add simultaneously a hard central shaft 4 and can solve the rise sharply heat shock resistance holding capacity of rapid drawdown of skeleton body opposing temperature effectively, be difficult for making the heater strip distortion.Simultaneously, the insulating washer of setting up 7 can increase the distance between electrical heating wire 3 and hard radiant tube 1 tube wall effectively, thereby has reduced some heater strip 3 because of being out of shape the possibility that the back contacts with the radiant tube tube wall.
