An anchoring structure in high temperature zone of rotary heat equipment

Abstract

An anchoring structure for the high-temperature area of rotation thermal equipment is characterized in that 'V'-shaped metal anchoring parts, 'Y'-shaped metal anchoring parts, oblique triangle metal anchoring parts and high-temperature-resistance non-metal building blocks with concave and convex grooves are used to anchor a lining. The anchoring structure has the advantages that the kiln lining is anchored by the various-shaped stainless steel metal anchor parts and the high-temperature-resistance non-metal building blocks which are fixedly welded on the inner wall of an outer steel shell in a staggered manner, the kiln lining is built into a specially-combined high-temperature-resistance concrete part which is high in overall strength and operate stably for a long term, the integrity of the kiln lining is increased greatly when the kiln lining moves along with the rotation thermal equipment, the destruction action, caused by the slip frequency generated by inertia, of the kiln lining is lowered, the overall strength and the anchoring performance of the kiln lining are increased, and operation stability of the kiln lining is increased greatly.

Description

technical field [0001] The invention relates to the anchorage of the kiln lining in the rotary heat equipment, in particular to an anchor structure in the high temperature zone of the rotary heat equipment. Background technique [0002] When the cylindrical rotary thermal equipment is lined with refractory concrete as a whole, due to the high temperature of the kiln lining in the high temperature section, a larger gap will be generated between the steel shell and the kiln lining due to different thermal expansions, and a greater gap will be generated during the rotating operation of the thermal equipment. Inertial slip causes the steel shell to separate from the kiln lining. The kiln lining is damaged due to the centrifugal force, centripetal force and inertial slip between the steel shell due to its own weight and the movement heat load of the process material. collapse. Therefore, it is necessary to bind the kiln lining to the steel shell more tightly, minimize the gap be...

Problems solved by technology

[0003] In order to solve the problem of low service life of the kiln lining due to the deformation and failure of the kiln lining anchors in the high-temperature section of the existing cylindrical rotary heat equipment, the present invention provides an anchor structure in the high-temperature zone of the rotary heat equipment. A variety of different anchors and anchor structures are set in the lining to make the binding force between the kiln lining and the steel shell in the high temperature section more firm and stable, effectively reducing the gap between the steel shell and the kiln lining and Slip movement overcomes the shortcoming of the single use of metal anchors to fix the kiln lining to be elongated and deformed in the high-temperature zone. The kiln lining shakes during the operation of the kiln lining, which greatly improves the life of the kiln lining in the high-temperature zone of the cylindrical thermal equipment. The working cavity inside the kiln lining can be changed arbitrarily according to the process requirements.
