Roller kiln

Abstract

The invention discloses a roller kiln. The roller kiln comprises a furnace body with a hearth, wherein more than one partition curtain is arranged in the hearth through a mounting assembly; the mounting assembly comprises a lower supporting cross beam and an upper supporting cross beam supported on the lower supporting cross beam; the furnace body is provided with two supporting mounting surfaceswhich are correspondingly arranged on two sides of the hearth; two ends of the lower supporting cross beam are correspondingly and correspondingly supported and arranged on the two supporting mountingsurfaces; two ends of the upper supporting cross beam are correspondingly and correspondingly positioned above the two supporting mounting surfaces; and the partition curtains are supported and arranged on the upper supporting cross beam. The roller kiln has the advantages of long service life, high safety and the like.

Description

technical field [0001] The invention relates to the technical field of heat treatment kiln equipment, in particular to a roller kiln. Background technique [0002] In the roller kiln, it is necessary to set a partition curtain in the furnace to divide the furnace into different temperature zones. The partition curtain of the existing roller kiln is to set vertical grooves on the furnace walls on both sides of the furnace, and the multiple pipes are separated from each other. Stack from bottom to top to form a partition structure. The pipe fittings are easily broken due to the corrosive gas and high temperature in the furnace. The falling of the broken pipe fittings will affect the partition effect and affect the normal production of the roller kiln, and the heat insulation of multiple stacked pipe fittings Poor performance, difficult to disassemble and maintain. [0003] In addition, the vault of the existing roller kiln is composed of multiple rows of vaults arranged in se...

Problems solved by technology

This kind of vault has stable structure, long service life, high strength and strong corrosion resistance, but its maintainability is poor. All refractory bricks lose their supporting structure, which will cause the vault to collapse as a whole), and for some kiln maintenance operations that need to dismantle the vault, it needs to be carried out under the condition of stopping production or even shutting down the furnace, resulting in extremely inconvenient maintenance , and affect production efficiency

At the same time, under the strong corrosion reaction atmosphere of lithium battery materials and other materials, it is inevitable that kiln furniture such as saggers or temperature zone partitions will be damaged during the production process. These damaged kiln furniture exist inside the furnace and are stuck on the transmission roller. If it cannot be taken out in time, the continuous production will be affected at least, and a major safety accident of the arch kiln will occur at the worst.

For the damage of these kiln furniture, usually the roller sticks stuck to the kiln furniture are pulled out to make the kiln furniture fall to the bottom of the furnace, and then the rollers are put on again, and then enter the furnace for cleaning when the furnace is shut down for maintenance. , and the damaged kiln furniture falls to the bottom of the furnace, not only the risk of damaging the heating elements and other components at the bottom of the furnace, but also the subsequent cleaning is extremely inconvenient
