Lining structure of storing belt on upper part of kiln body of shaft kiln

Abstract

The invention relates to a lining structure of a storing belt on the upper part of a kiln body of a shaft kiln. The lining structure comprises fire-resistant and heat-insulating castables and a castable protective sleeve; the castable protective sleeve is constituted by a bottom annular plate, stud partition plates and an internal hoarding; the bottom annular plate is in a circular ring shape, theedge of the outer circle is fixedly connected with the inner wall of a kiln shell corresponding to the storing belt, and the edge of the inner circle is fixedly connected with the bottom edge of theinternal hoarding; the internal hoarding is in a cylinder shape; the kiln shell, the bottom annular plate and the internal hoarding form an annular groove with the U-shaped cross section jointly; andthe multiple stud partition plates are evenly arranged in the annular groove in the circumferential direction, the annular groove is partitioned into a plurality of arc-shaped groove sections, and each arc-shaped groove section is filled with the corresponding fire-resistant and heat-insulating castable. The castable protective sleeve is arranged on the outer sides of the fire-resistant and heat-insulating castables, the castable protective sleeve and the kiln shell of the shaft kiln are connected into a whole, the lining structure is simple in structure and high in strength and can achieve agreat protection effect on the fire-resistant and heat-insulating castables, thus the service life of a lining is prolonged, and long-term and stable continuous production of the shaft kiln is ensured.

Description

technical field [0001] The invention relates to the technical field of shaft kilns, in particular to a lining structure for a material storage belt at the upper part of a shaft kiln body that can prevent materials from directly impacting the castable liner. Background technique [0002] Usually, the inner lining of the upper material storage belt of the preheating zone of the shaft kiln body is made of refractory bricks or poured with refractory and heat-insulating castables, wherein the refractory and heat-insulated castables are fixedly connected to the inner wall of the kiln shell through multiple anchor hooks , compared with the lining made of refractory bricks, it has the advantages of high overall strength and better thermal insulation. [0003] When the shaft kiln is working, the materials to be calcined are evenly distributed to the storage belt on the top of the kiln through the distributor on the top of the shaft kiln, and the materials scattered near the inner lin...

AI Technical Summary

Problems solved by technology

The problem with this structure is that after the skirt body is impacted by materials for a long time, the suspenders will loosen, eventually causing the suspenders and the steel skirt to fall off as a whole.

In addition, this structure is relatively bulky, which has seriously affected the smooth production. Therefore, it is urgent to invent a protection device for the lining of the upper storage belt of the preheating zone of the shaft kiln body. The structure is required to be simple, compact, and small, and it can be used for a long time. To reduce the maintenance frequency and prolong the service life of the kiln lining
