Embodiment Construction

[0026] As shown in the figure, an anchoring method for the kiln lining of a cylindrical rotary heat equipment is to apply anchors to the root of the kiln lining and the upper part of the kiln lining to stably fix each part of the lining at the initial set position. , and the anchor point at the root of the kiln lining is at least 1.5 times that of the upper part of the kiln lining. The anchors include "V"-shaped anchors 1, "Y"-shaped anchors 2, oblique triangle anchors 3, and The refractory blocks 4 are configured with anchors in different combinations according to the temperature range of different regions of the kiln lining, so as to maintain the effectiveness of the entire kiln lining anchors for kiln lining anchoring.

[0027] The kiln lining selects different combinations of anchors according to the furnace lining temperature. When the furnace lining temperature is ≤300°C, the anchors are made of ordinary carbon steel bars to make "V"-shaped anchors 1 and "Y"-shaped anc...

Abstract

Provided is an anchoring method of a kiln liner of cylindrical rotary thermal equipment. Three kinds of metal anchoring parts of different shapes are manufactured, refractory building block anchoring bricks with convex grooves and concave grooves are designed and manufactured, fixing anchoring force is exerted on the root of the kiln liner, stabilizing anchoring force is exerted on the middle of the kiln liner, pulling anchoring force is exerted on the upper portion of the kiln liner, and the anchoring points at the root of the kiln liner are at least 1.5 times those of the middle or the upper portion of the kiln liner. Four kinds of metal anchoring parts and the anchoring bricks made of refractory building blocks exert anchoring force on the root, the middle and the upper portion of the kiln liner, long-term stable anchoring is formed in the kiln liner of the rotary thermal equipment from normal temperature to high temperature more than 1400 DEG C, sliding and displacement of the kiln liner are solved effectively, combination intensity of the kiln liner and the inner wall of a furnace body is enhanced, the kiln liner is prevented from falling off or being damaged, the service life of the kiln liner is prolonged, the number of maintenance times is reduced, cost is saved, and the utilization rate of the equipment is improved.

Description

technical field [0001] The invention relates to the anchoring of the kiln lining in the rotary heat equipment, in particular to an anchoring method for the kiln lining of the cylindrical rotary heat equipment. Background technique [0002] In the heating field of various industries, it is widely used in the rotary heating equipment with kiln lining installed inside the cylindrical steel shell, also known as rotary kiln, rotary dryer, rotary roasting furnace, rotary calciner, etc. The rotary part of the rotary heat equipment is all made of steel shell. Due to the high process production temperature and thermal erosion during the operation of the equipment, the steel shell of the rotary heat equipment will be deformed or softened. For this reason, it is necessary to add a layer of non-metallic lining inside the steel shell to resist higher temperature and thermal erosion. The furnace lining can be prefabricated on site with bulk refractory insulation materials. During the pr...
