Embodiment 1

[0020] Example 1: Remove the original pouring material to expose the base layer, and then use ribs with a thickness of 2cm to splice the base layer into a circular kiln mouth ring body 1, and ensure that there are several square grids between the ribs grid, and then fill the grid with the above-mentioned formula and ratio of castables. Before filling the castables, take the raw materials of each component in proportion and mix them; A layer of lightweight pouring layer 3 is poured on the surface of the plate layer 2. The lightweight pouring layer 3 is the pouring layer 2 from which heat-resistant steel fibers and refractory glass fibers have been removed. The lightweight pouring layer 3 can be dried.

Abstract

The invention discloses a kiln nose ring structure of a cement rotary kiln. The structure comprises a kiln nose ring body. A rib plate layer is arranged on the inner wall of a variable-diameter position of the kiln nose ring body. The rib plate layer is formed by splicing a plurality of rib plates which intersect transversely and vertically, and a plurality of gratings are defined by the rib plates. The gratings are filled with castables. A light casting layer is further cast on the surface of the rib plate layer. The thickness of the light casting layer is 400 mm, and the thickness of the rib plate layer is 300 mm. By the adoption of the kiln nose ring structure of the cement rotary kiln, the problems of an existing rotary kiln nose that the underfiring rate is large, heating is nonuniform, materials are prone to overburning, and the kiln tail is prone to material leakage can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of processing building materials, in particular to the technical field of sludge separation, and in particular to a kiln mouth ring structure of a cement rotary kiln. Background technique [0002] At present, in the field of cement production, rotary kilns are generally used for production. The inner diameter of the kiln ring of the commonly used rotary kiln is too large, which is 3.0m. The height of the ring itself is 500mm, the height of which is 250mm except for the refractory bricks, and the height that prevents the material from moving forward in the kiln is 250mm. Due to the obstruction of the kiln mouth ring, the accumulation length of the material extending into the kiln is 4.089m, and the accumulated material volume is 4.21 tons. The following impacts on the production of rotary kiln: [0003] When the material passes through the calcination zone of the rotary kiln: a faster kiln speed can take in...
