Abstract
The utility model discloses an electrode belt cover annulus baking furnace with a concrete furnace cover, two parallel furnace chambers are connected with each other in series, a concrete furnace cover is arranged outside the fire resistant built body of the furnace chambers, a metal anchor mount connected the fire resistant built body and the concrete furnace house is arranged in the fire resistant built body and the concrete furnace house. When the concrete furnace cover is used, the dry sand is not needed, the inner lining of the fire resistant material in side wall of the furnace chamber is not easy to deform, the modification on the furnace has considerable influences on the maintenance cost of operation and the furnace utilization efficiency. The utility model has the advantages of the less deformation of the furnace two sides and the center working surface and the side wall of the furnace chamber, long service life, lower maintenance cost and good product quality.
Description
Technical field:
The utility model relates to the negative electrode ring-type baking furnace with cover of the band concrete furnace shell of a kind of roasting cathode carbon pieces or other electrode products, belongs to the roaster technical field.
Background technology:
Cathode baking furnace mainly is to be used for roasting charcoal piece to make it to become the equipment of the used negative electrode of electrolytic cell.Present two problems of negative electrode ring-type baking furnace with cover ubiquity: be that boiler face both sides and middle part working face sink on the one hand; Be the distortion of furnace chamber arc side wall on the other hand, shortened the stove life-span.The problem of these two aspects all is because the furnace chamber side wall of existing negative electrode ring-type baking furnace with cover has used unsetting material Zhao dry sand caused outward.Because dry sand has flowability, when its contraction was sunk, the boiler face working face of its furnace chamber will sink, and the side-thrust that is produced when dry sand sinks simultaneously acts on the arc side wall, makes it distortion, caused the interior negative pressure system of stove destroyed, and product is subjected to oxidation affects.Therefore the result of use of existing negative electrode ring-type baking furnace with cover still is not ideal enough
Summary of the invention:
The purpose of this utility model is: provide the negative electrode ring-type baking furnace with cover of the band concrete furnace shell that the distortion of a kind of boiler face both sides and middle part working face and furnace chamber side wall is less, grow service life, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises furnace chamber (1), the negative electrode ring-type baking furnace with cover of this band concrete furnace shell is serially connected mutually by the parallel furnace chamber (1) of two row, and is provided with concrete furnace shell (3) in the outside of the refractory masonry (2) of these two row furnace chambers (1) that are serially connected mutually.
In refractory masonry (2) and concrete furnace shell (3), be provided with the metal anchorage (4) that refractory masonry (2) and concrete furnace shell (3) are linked together.
Owing to adopted technique scheme, the utility model supports refractory masonry with the concrete furnace shell, and connects concrete furnace shell and refractory masonry with metal anchorage, adopts this mode can remove the influence that dry sand produces.After using concrete furnace shell of the present utility model, no longer need dry sand, its furnace chamber side wall refractory lining also be difficult for to produce distortion, and such change is kept maintenance cost and the stove utilization rate that operation produces to stove will produce considerable influence.In addition, the concrete furnace shell is to the support force of the refractory material support force greater than dry sand and common brick, and the furnace binding after the change develops towards the maximization direction stove and plays decisive role.Therefore, the utility model compared with prior art, the utility model not only has the advantage that boiler face both sides and middle part working face and the distortion of furnace chamber side wall are little, service life is long, and the utility model also has, and operation and maintenance cost hangs down and the advantage of the good product quality that roasting goes out.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the A-A cross-sectional schematic of accompanying drawing 1;
Accompanying drawing 3 is the local enlarged diagram of the B portion of accompanying drawing 2.
The specific embodiment:
Embodiment of the present utility model: furnace chamber (1) can adopt method of the prior art to build by laying bricks or stones, promptly adopt refractory brick to build furnace chamber (1) by laying bricks or stones as refractory masonry (2), during making, mode by existing negative electrode ring-type baking furnace with cover is serially connected the parallel furnace chamber (1) of two row mutually, and the concrete furnace shell (3) that is used to support refractory masonry (2) is produced in the outside at the refractory masonry (2) of these two row furnace chambers (1) that are serially connected mutually, when making concrete furnace shell (3), in the exit flue junction of concrete furnace shell (3), concrete furnace shell (3) should be walked around the exit flue of furnace chamber (1) with each furnace chamber (1); For refractory masonry (2) and concrete furnace shell (3) are linked together more reliably, in refractory masonry (2) and concrete furnace shell (3), bury the metal anchorage (4) that refractory masonry (2) and concrete furnace shell (3) can be linked together underground, promptly use metal anchorage (4) to connect concrete furnace shell (3) and refractory masonry (2), when burying metal anchorage (4) underground, draw brick to be uniformly distributed in refractory brick side wall part as refractory masonry (2), one end of metal anchorage (4) is colluded in drawing the brick hole, its other end then penetrates with in the wall of concrete furnace shell (3), so promptly can be made into the negative electrode ring-type baking furnace with cover of band concrete furnace shell.
Claims (2)
1. negative electrode ring-type baking furnace with cover with the concrete furnace shell, it comprises furnace chamber (1), it is characterized in that: the negative electrode ring-type baking furnace with cover of this band concrete furnace shell is serially connected mutually by the parallel furnace chamber (1) of two row, and is provided with concrete furnace shell (3) in the outside of the refractory masonry (2) of these two row furnace chambers (1) that are serially connected mutually.
2. according to the negative electrode ring-type baking furnace with cover of the band concrete furnace shell of claim 1, it is characterized in that: in refractory masonry (2) and concrete furnace shell (3), be provided with the metal anchorage (4) that refractory masonry (2) and concrete furnace shell (3) are linked together.
