Abstract
The utility model relates to a heating furnace for sintering rare earth. The heating furnace comprises a hearth (1), a furnace body (2), a heat insulation cotton layer (3) and a heating element (4), wherein the furnace body (1) is coated by the heat insulation cotton layer (3), and the heating element (4) penetrates through the hearth (1), the furnace body (2) and the heat insulation cotton layer (3). The utility model is characterized in that a porcelain bushing (5) is arranged outside the heating element (4) positioned in the heat insulation cotton layer (3). In the heating furnace for sintering rare earth, due to the heat resisting protective porcelain bushing, direct contact of a carbon rod and the heat insulation cotton layer is avoided; the heating element, that is, a carbon rod, is prevented from being sintered together with the heat insulation cotton; and no damage can be caused to the furnace body when the heating element is replaced. A gap between the carbon rod and the protection porcelain bushing is tightly filled with a heat insulation cotton plug, and the heating efficiency is ensured.
Description
(1) technical field
The utility model relates to a kind of rare earth sintering heating furnace.
(2) background technology
Traditional rare earth sintering heating furnace comprises burner hearth, body of heater and is coated on the outer heat-preservation cotton layer of body of heater that heating element heater carbon-point directly passes the heat-preservation cotton layer of burner hearth, contacts with heat-preservation cotton.Its shortcoming is: behind the high temperature, heating original paper carbon-point and heat-preservation cotton sintering often damage body of heater together when changing the heating original paper for a long time.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of rare earth sintering heating furnace is provided, its heating original paper carbon-point and heat-preservation cotton can sintering together, when thermal element is separated in replacing, can not cause damage to body of heater.
The purpose of this utility model is achieved in that a kind of rare earth sintering heating furnace, it comprises burner hearth, body of heater, heat-preservation cotton layer and heating element heater, described heat-preservation cotton layer is coated on outside the body of heater, described heating element heater passes burner hearth, body of heater and heat-preservation cotton layer, it is characterized in that: the heating element heater that is in the heat-preservation cotton layer is outside equipped with insulator.
The beneficial effect of the utility model rare earth sintering heating furnace is:
The existence of resistant to elevated temperatures protection insulator has stoped carbon-point to contact with the direct of heat-preservation cotton layer, heating original paper carbon-point and heat-preservation cotton can sintering together, when thermal element is separated in replacing, can not cause damage to body of heater.Carbon-point and the space heat-preservation cotton jam-pack of protecting insulator have guaranteed the efficiency of heating surface.
(4) description of drawings
Fig. 1 is the utility model rare earth sintering heating furnace structure schematic diagram.
Among the figure:
Burner hearth 1, body of heater 2, heat-preservation cotton layer 3, heating element heater 4, insulator 5.
(5) specific embodiment
Referring to Fig. 1; the rare earth sintering heating furnace that the utility model relates to; it comprises burner hearth 1, body of heater 2, heat-preservation cotton layer 3, heating element heater 4 and insulator 5; heat-preservation cotton layer 3 is coated on outside the body of heater 1; heating element heater 4 passes burner hearth 1, body of heater 2 and heat-preservation cotton layer 3, and the heating element heater 4 that is in heat-preservation cotton layer 3 is outside equipped with the insulator 5 of protection usefulness.
Heating element heater 4 is a carbon-point.
Gap heat-preservation cotton jam-pack between heating element heater 4 and the insulator 5.
Claims (1)
