Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the utility model, fall within the scope of protection of the utility model.
Embodiments of the utility model:
as shown in figures 1-4, the rotary kiln lining precast block comprises a precast layer 1, a heat insulation layer 3 and an anchor rib 2, wherein the precast layer 1 is square, namely cuboid, and one side, adjacent to the inner wall of a kiln body, of the precast block during installation can be arc-shaped, so that the precast block can be better attached. The insulating layer 3 is located in the preformed layer 1, and the outer side surface of the insulating layer 3 is flush with the bottom surface of the preformed layer 1, which is denoted as insulating surface 31. The heat insulating layer 3 adopts high-alumina light-weight bricks, which are the prior art. Notches 32 are arranged on the left side and the right side of the heat insulation layer 3 to realize clamping fit with the prefabricated layer 1; the outer side is the portion located between the two notches 32. The two sides of the high-alumina light-gathering brick are provided with the notches 32 instead of the standard cuboid, so that the connection with the prefabricated layer 1 is firmer, and in the manufacturing process of the prefabricated layer 1, the castable of the prefabricated layer 1 can submerge the notches 32 on the two sides, and only the bottom surface of the high-alumina light-gathering brick is left.
The left and right sides of prefabricated layer 1 are equipped with an arc groove 11 respectively, and arc groove 11 link up the setting along the fore-and-aft direction. The anchor muscle 2 is equipped with two, and two anchor muscle 2 bilateral symmetry set up, and anchor muscle 2 is the shape of +.2, and the one end of anchor muscle 2 stretches out from the bottom of prefabrication layer 1, and the other end stretches out from arc groove 11.
By arranging the anchoring ribs 2, one end of each anchoring rib is welded during installation and construction, namely the inner wall of the kiln body is welded, and the prefabricated block is fixed. The other end (the end extending out of the arc-shaped groove 11) can play a role in strengthening, and compared with the casting material which is directly poured into the single arc-shaped groove 11, the effect is better. The castable is also an existing concrete material, and the mode of combining the precast block and the castable to manufacture the lining is the prior art, so the castable is not an improvement of the utility model. The prefabricated blocks are arranged in a straight line along the axial direction of the kiln body, a plurality of rows are arranged along the circumferential direction of the kiln body at intervals, strip-shaped pouring grooves are formed in the spaces between the prefabricated blocks in the adjacent rows, and after the prefabricated blocks are welded and fixed, pouring material construction can be directly carried out without templates, so that the time is saved.
