Problems solved by technology

Because water is used for mixing during the construction of the castable, the structure of the castable contains a large amount of free water. During the later baking process, the free water evaporates and combines with the magnesia bricks to hydrate the magnesia bricks, resulting in magnesia bricks. Cracking and reduced strength make this part the most vulnerable part of the lime kiln, requiring frequent maintenance to maintain the production of the lime kiln
[0003] Therefore, there are above-mentioned inconveniences and problems in the construction method of the known Maerzi lime kiln hanging cylinder

Embodiment 1

[0035] The construction method of Maierzi lime kiln suspension cylinder of the present invention comprises the following steps:

[0036] a. Prefabricated baking device, comprising the following steps:

[0037] see now figure 1 , figure 1 It is a structural schematic diagram of a baking device according to an embodiment of the present invention.

[0038] (1) Prefabricate several baking devices according to the design drawings of the hanging cylinder of the Maerz lime kiln. As shown in the figure, the baking device uses 30*3mm flat steel 1 to make the frame of the baking device, and the bottom of the frame is provided with a support The structure is used to carry insulation bricks, and the frame is made to form a rectangular flat steel frame with an area of ​​500*372mm;

[0039] (2) Put 6 pieces of diatomite heat insulation bricks of 230*114*64mm in each flat steel frame. After the heat insulation bricks are put in, arrange grooves on the heat insulation bricks in a back shap...

Abstract

A construction method for a hanging cylinder of a Maerz lime kiln, which is characterized in that it includes the following steps: a. prefabricating the baking device, b. setting up the pouring mold and the construction of the pouring material for the hanging cylinder, c. removing the mold and placing the prefabricated baking device in the pouring The lower part of the material is connected to the PLC automatic control system for baking and masonry of e magnesia bricks. The construction method of the hanging cylinder of the Maerz lime kiln of the present invention has the advantages of reasonable design of construction steps and simple operation, greatly improves the quality of the hanging cylinder of the Maerz lime kiln, reduces the frequency of maintenance, improves the service life of the kiln body, and has a long-term effect with a small Cost to achieve greater long-term benefits and win the advantages of competitiveness.

Description

technical field [0001] The invention relates to a construction method of a lime kiln, in particular to a construction method of a hanging cylinder of a Maerz lime kiln. Background technique [0002] Maerz lime kiln is a double chamber parallel flow regenerative lime kiln, in which the hanging cylinder is the most important structure in the lime kiln. In the production process of the lime kiln, its substructure is a structure of castable + magnesia bricks, which is easily damaged by frequent impacts of limestone for a long time. The general construction process of the hanging cylinder of the Maerz lime kiln is to first construct the castable, and then build magnesia bricks on the surface of the castable. At present, part of the Maerz lime kiln has been introduced in China, and its subsequent introduction will be further expanded. However, the domestic conventional Maerz lime kiln hanging cylinder construction method is to start the upper magnesia brick after the natural main...
