Abstract
The utility model discloses an isolating wall for pressure reducing and electric leakage prevention of a furnace body. The isolating wall is formed by refractory bricks; a plurality of perpendicular gas holes are distributed at an equal distance on the axial line of the isolating wall, one-way expansion seams extend from the perpendicular gas holes towards the two sides of the isolating wall and distributed on the upper and the lower sides of the perpendicular gas holes in a staggered manner, and the expansion seams on the two sides are not superposed to each other. In the technical scheme, the expansion seams on the two sides of the isolating wall are not communicated with each other, so that the coke powders on the two sides of the furnace body are not communicated with each other, and the root cause of electric leakage is cut. On the other hand, in the technical scheme, the heat of the isolating wall is rapidly dissipated through the air holes, which reduces the influence of thermal expansion and cold shrinkage on the wall body and prolongs the service life of the wall body.
Description
Technical field
The utility model relates to a kind of reduced-pressure anticreeping separation wall of furnace body, especially a kind of reduced-pressure anticreeping separation wall of furnace body that is used for graphitizing furnace.
Background technology
Graphite electrode is widely used in metallurgy industry, calculates one ton of steel of every refining according to industry and need consume the 150kg graphite electrode, and therefore, graphite electrode belongs to the running stores of metallurgy industry, and consumption is very big, and the electric conductivity of electrode directly influences metallurgical efficient.The most common graphite electrode processing method is to feed big electric current generation high temperature the former base of graphite is carried out graphitization in horizontal electric resistance furnace at present, current processing method is the former base series connection of a plurality of graphite to be couched be placed in the resistance furnace, on the former base of graphite, cover thick coke powder heat-insulation layer, the body of heater divider wall of prior art is owing to will overcome the body of wall expanded by heating, meet the destruction of cold contraction to body of wall, usually adopt on body of wall and stay an expansion joint every a segment distance, this expansion joint can be ventilated the body of wall both sides, the existence at this expansion joint, make the coke powder intercommunication of divider wall both sides, after adding electric current, electric current makes both sides body of heater electric leakage by coke powder, consume a large amount of electric energy, and make graphite former base graphitization in two ends insufficient, influenced the electrical efficiency of graphite electrode.
Summary of the invention
Technical problem to be solved in the utility model is the technical problem of divider wall electric leakage.
In order to solve the problems of the technologies described above, the utility model provides a kind of reduced-pressure anticreeping separation wall of furnace body, this divider wall is to be made of refractory brick, equidistant some vertical pores that distribute on the axis of this divider wall, and some vertical pores are to unidirectional expansion joint of opening, divider wall both sides respectively
Shape distributes, and promptly this expansion joint is the parallel distribution of staggering up and down, and this expansion joint, both sides does not overlap mutually.
As optimal technical scheme of the present utility model, described expansion joint is equally spaced.
Further, this divider wall top has a through hole to connect all vertical pore, and two openings of this through hole are at top, described divider wall two ends.
The beneficial effects of the utility model are:
1, the expansion joint of the divider wall both sides in technical solutions of the utility model UNICOM not mutually makes the body of heater both sides coke powder can not intercommunication, has cut off the root of electric leakage.
2, passage distributes the heat that is delivered on the divider wall fast in the technical solutions of the utility model, and the pressure to body of wall of having reduced to expand with heat and contract with cold has prolonged service life of body of wall.
Description of drawings
Below in conjunction with the drawings and specific embodiments technical solutions of the utility model are described in further detail.
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of prior art divider wall;
Fig. 2 is the structural representation of the utility model body of heater decompression divider wall.
The specific embodiment
Fig. 1 is the structural representation of prior art divider wall.The prior art divider wall is to be built into by refractory brick, for the destruction that prevents to expand with heat and contract with cold to body of wall 1, prior art divider wall 1 leaves an expansion joint 2 every a segment distance, and this expansion joint 2 makes divider wall 1 both sides intercommunication, the coke powder of both sides is communicated, serious leaky is arranged.
Fig. 2 is the structural representation of the utility model body of heater decompression divider wall.This divider wall 1 is to be made of refractory brick, equidistant some vertical pores 3 that distribute on the axis of this divider wall 1, and some vertical pores 3 equidistantly are to the unidirectional expansion joint of opening 2, divider wall 1 both sides respectively
Shape distributes, and promptly this expansion joint is the parallel distribution of staggering up and down, and this expansion joint, both sides 2 does not overlap mutually.This divider wall 1 top has a through hole to connect all vertical pore 3, and two openings of this through hole are at top, described divider wall two ends.On the one hand, the expansion joint 2 of these divider wall 1 both sides is UNICOM not mutually, makes the body of heater both sides coke powder can not intercommunication, has cut off the root of electric leakage; On the other hand, passage 3 distributes the heat that is delivered on the divider wall 1 fast, and the pressure to body of wall of having reduced to expand with heat and contract with cold has prolonged service life of body of wall.
The utility model is not limited to the described scope of the foregoing description, and every technology distortion of doing according to technical solutions of the utility model all falls within the protection domain of the present utility model.
