Description

Graphitization furnace side wall anti-toppling device

Technical Field

The utility model relates to the field of graphitizing furnaces in graphite products, in particular to a novel graphitizing furnace side wall anti-toppling device.

Background

Currently, manufactured graphite articles are generally produced using graphitization furnaces. With the increase of the productivity requirement, the graphitization furnace gradually moves towards a higher and wider direction, so that the side wall of the graphitization furnace and the maintenance structural stability of the side wall of the graphitization furnace are required to be higher. In view of this, the main countermeasures are now: (1) The refractory material for building the side wall adopts refractory bricks with mortises, so that each layer of bricks of the built side wall can be mutually connected to improve the overall stability of the side wall; (2) Steel upright posts are uniformly distributed at corresponding positions of the side wall of the graphitization furnace so as to improve the outward tilting resistance of the side wall.

Because the graphitization furnace has a long production period, most of the time in the furnace is occupied by the filling material, and the two measures can better cope with the trend of outward dumping of the furnace wall, thereby maintaining the overall stability of the side wall. Then, the inner surface of the side wall of the graphitization furnace has burning loss at the local refractory bricks and brick joints due to the high temperature effect during production, and the side wall of the graphitization furnace has a tendency to topple into the furnace after the graphitization furnace filling material is discharged. Therefore, the current graphitization furnace side wall maintenance structure obviously cannot meet the safety production requirements of the existing graphitization process.

Disclosure of Invention

The utility model aims at: the side wall anti-toppling device for the graphitized furnace is simple in structure and manufacture, low in implementation cost, stable in service performance, capable of effectively relieving the trend of toppling of the side wall in the furnace, and low in operation and maintenance cost, and can ensure safe production of products.

The utility model is realized in the following way: the graphitizing furnace side wall anti-toppling device comprises a draw hook, an anchoring hook and a rigging turnbuckle, wherein a hook body of the draw hook is fixedly connected with the embedded beam, and the end head of the draw hook is positioned outside the embedded beam; the hook body of the anchoring hook is fixedly connected with the retaining wall beam, and the end head of the anchoring hook is positioned outside the retaining wall beam; the embedded cross beam is embedded into the side wall of the graphitizing furnace, and the retaining wall beam is connected with the retaining wall column; the ends of the draw hooks fixed on the embedded cross beam correspond to the ends of the anchoring hooks fixed on the retaining wall beam, and the two corresponding draw hook ends and the ends of the anchoring hooks are connected through a turnbuckle of the rigging.

The draw hooks and the anchoring hooks are all arranged at intervals of 400-500 mm.

And a plurality of retaining wall beams are uniformly arranged among the retaining wall columns.

The two ends of the turnbuckle of the rigging are respectively connected with the draw hook and the anchoring hook in an inserting and engaging way through bolts, and the connecting way of the engaging way enables the connecting piece of the device to be convenient to install and detach.

When the graphitization furnace is not filled with the filler in actual production operation, the side wall of the furnace is likely to have local burning loss on one side close to the furnace due to the high temperature effect in production, so that the side wall of the furnace has a tendency to topple over in the furnace. Through the tight connection of the anti-toppling devices of the graphitization furnace, the side wall of the furnace can be pulled, so that the toppling trend of the graphitization furnace towards the inside of the furnace is reduced. Meanwhile, under the condition that the refractory bricks expand with heat and contract with cold in the production process, the connecting mode can not excessively limit the expansion of the furnace wall up, down, left and right, and further prevent the damage of the drag hook structure. In addition, when the graphitizing furnace is internally provided with the filler, the side thrust generated by the filler can increase the outward dumping trend of the furnace wall, and the integral external fixing structure formed by the retaining wall column and the retaining wall beam in the graphitizing furnace can increase the dumping resistance of the side wall.

By adopting the technical scheme, the utility model provides the graphitization furnace side wall anti-toppling device which is simple in construction and manufacture, low in implementation cost, stable in use performance, capable of guaranteeing safe production of products and low in operation and maintenance cost, and the tendency of toppling of the graphitization furnace side wall is effectively relieved.
