Internal structure of furnace body

Abstract

The invention provides an internal structure of a furnace body. The internal structure comprises a liner; chamber bodies of the liner are connected with a partition plate; the partition plate is usedfor dividing the liner into at least two chamber bodies; one chamber body is a working chamber; an internal rolling wheel mechanism is arranged inside the working chamber; a workpiece is placed on theinternal rolling wheel mechanism; and a fan is arranged at one side of the liner. On one hand, the internal structure provided by the invention can realize uniform heating or cooling of the workpiece; and on the other hand, the inside of the liner is made from a high temperature resisting material and can resist a temperature larger than or equal to 450 DEG C, so the internal structure is especially applicable to places which can bear strong burning and high pressure.

Description

technical field [0001] The invention relates to a furnace body structure, in particular to an inner structure of a furnace body. Background technique [0002] The existing body of furnace mainly has the following defects: [0003] First, the working chamber and the heating chamber are mostly located in different chambers, resulting in a complex structure; or the heating chamber and the working chamber are in the same chamber, but there is no isolation between the two. If the workpiece is close to the heating body, the workpiece The temperature at the end close to the heating body will be higher than the temperature at other positions, resulting in uneven heating of the workpiece. Even if there is a partition in the furnace body, on the one hand, it is not suitable for high-temperature environments, and its strength is low, so it cannot be used in high-burning and pressure-bearing occasions, and the versatility is poor; on the other hand, the existing partitions have fixed d...

AI Technical Summary

Problems solved by technology

Because the temperature of the working chamber is very high, it is easy to damage the rollers, and the material requirements of other corresponding parts for installing the rollers are also high, and it is not easy to install on the inner side of the inner tank

There are also rollers that play the role of lifting, rather than transporting the workpiece. Most of the workpieces are moved into the working chamber manually, or moved in by a rail trolley, which is not only time-consuming and laborious, but also requires additional equipment. integration

Moreover, the existing roller mechanism is only suitable for occasions where the temperature resistance is <450°C, and is not suitable for high temperature environments

[0005] Thirdly, most of the heat-insulating shells of the existing furnace body are made of stainless steel, and the surface of the shell is smooth. Once the shell is subjected to high temperature, it is easy to be heated and expand, resulting in stress concentration. Once it is cooled immediately after being heated, it will It is easy to shrink, resulting in a greatly reduced service life of the shell, which is not only expensive, but also reduces work efficiency

Although the glass fiber mat has the advantages of heat resistance and corrosion resistance, the weight of the glass fiber mat is large and the bending resistance is poor, so it is not suitable for the inner tank structure of the furnace body.

[0007] Fifth, the existing liner is usually used as a working chamber for workpiece heating. Because the working chamber volume of the existing furnace body is small, the connection method between the liner and the furnace body is usually to directly install the bottom of the liner on the Furnace frame, while the side of the inner tank does not support it

However, when the volume of the liner is large, that is, the volume of the workpiece is large, it is easy to generate vibration when the workpiece is placed in the liner, or when the workpiece is heated, which will cause the liner to shake and greatly reduce the stability.

[0008] Sixth, the existing inner shell and shell are fixedly connected to the furnace body. Once heated and expanded, it is easy to cause stress concentration at the connecting part
