Description

Combined type graphitizing furnace head and furnace tail structure

Technical Field

The utility model relates to a modular graphitizing furnace end stove tail structure belongs to industrial furnace kiln technical field.

Background

At present, the outer wall structure of the furnace head and the furnace tail of the graphitizing furnace is mostly in the form of an integrally cast heat-resistant concrete structure, and the middle part of the outer wall of the graphitizing furnace is provided with a hole for connecting and installing the furnace head or the furnace tail electrode and a carbon sliding block around the furnace head or the furnace tail electrode in a penetrating way. The structural form has the characteristics of good integrity of the furnace end and the furnace tail, simple structure, good production stability and the like, but causes great difficulty for the construction and installation of the electrode and the carbon sliding block. The electrodes and the carbon sliding blocks weighing several tons can be installed in place only after horizontally penetrating through the outer wall hole of the furnace end from the side part, so that the electrodes and the carbon sliding blocks cannot be hoisted in place at one time. Moreover, the installation is inconvenient, and the maintenance and the replacement of the furnace head or the furnace tail electrode or the carbon sliding block after the loss are particularly prominent in the future production.

On the other hand, the production mode of the graphitization furnace determines that the furnace end or the furnace tail electrode needs to make reciprocating pushing movement, and the friction force generated by the repeated horizontal movement drives the carbon sliding blocks around the electrode to make relative movement on the straight outer wall opening of the furnace end and the furnace tail of the furnace end, so that the carbon sliding blocks are loosened, the furnace end or the furnace tail electrode is eccentric, the graphitization production is influenced, and the electrode loss is accelerated.

In addition, part of the opinion is that the reinforcing mesh in the concrete outer wall of the integral furnace end and furnace tail forms a closed annular reinforcing conductive loop around the electrode, when strong current passes through the electrode during production, the annular loops can generate an electromagnetic eddy current effect, and further the reinforcing mesh generates heat at a weak position to cause production accidents such as burning-through of the concrete wall of the furnace end and furnace tail.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a modular graphitizing furnace end stove tail structure, it is good to keep original integral concrete furnace end stove tail wholeness, simple structure, when advantages such as production stability is good, can effectively solve furnace end or stove tail electrode and the difficult problem of the inconvenient installation of carbonaceous slider around it to make carbonaceous slider and furnace end stove tail outer wall combine the fastening, improve graphitizing furnace's life.

The technical scheme of the utility model as follows:

the utility model provides a modular graphitizing furnace end stove tail structure, the substructure of furnace end stove tail is the same basically with former integral concrete furnace end stove tail, cancels original closed furnace end or stove tail electrode trompil, changes into open slot structure in top, and the installation of furnace end or stove tail electrode and carbonaceous slider around being convenient for, at the top of electrode slot, fixes the electrode seal on whole furnace end stove tail with prefabricated concrete pressure beam that has the lug device, and movable concrete pressure beam is the same with the furnace end stove tail concrete outer wall material of fixing under it. Meanwhile, the carbon sliding blocks, the furnace end and furnace tail concrete outer walls around the carbon sliding blocks and the pressing beams are designed to be in a joggle connection mode, so that the outer walls, the pressing beams and the carbon sliding blocks are tightly and stably combined into a whole, and stable production of the graphitizing furnace is guaranteed.

Compared with the prior art, the utility model discloses fundamentally has solved the inconvenient this ubiquitous technological problem of graphitizing furnace integral furnace end stove tail outer wall structural installation and maintenance operation, to reducing workman's intensity of labour, improves the installation effectiveness and the production efficiency of stove and all has very important meaning. The utility model discloses also avoid effectively sliding the unstable situation of bringing furnace end stove tail structure because of electrode production operation, this is of value to the life who improves the stove very, and it is extravagant to reduce unnecessary production. Finally, the utility model discloses also can thoroughly stop whole furnace end stove tail structure and lead to the hidden danger of damaging because of the electromagnetic eddy current effect that probably produces during production.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The utility model discloses combination formula graphitizing furnace end stove tail structure includes concrete outer wall 1, carbonaceous slider 2, concrete pressure beam 3, flame retardant coating inner wall 4 and furnace end or stove tail electrode 5 etc. specifically sees attached 1 and 2. During construction, the outer edge part of the electrode groove of the concrete outer wall 1 is processed into a tenon joint structure form, and the corresponding outer edge parts of the carbon sliding block 2 and the concrete pressing beam 3 are processed into a mortise structure form (the concrete pressing beam 3 also has partial tenon joints) so as to be convenient for butt joint. The construction is that the concrete outer wall 1 is constructed and installed in place, the inner wall 4 of the fire-resistant layer is built to a corresponding height, after the carbon slide blocks 2 and the furnace head or furnace tail electrode 5 are sequentially installed in place, the building of the inner wall 4 of the fire-resistant layer is continuously completed, and finally the whole furnace head and furnace tail structure is sealed by the concrete pressing beam 3 according to the mortise and tenon position. Except for the furnace head or furnace tail electrode 5, other parts are bonded by adopting bonding materials such as refractory slurry and the like. The maintenance and the replacement after the production of the graphitizing furnace are reverse to the sequence.

It should be noted that the size, shape and the like of the tongue structure of each tongue groove can be adjusted correspondingly according to the production specifications, performances, requirements and the like of different graphitizing furnaces.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
