Abstract
The utility model relates to a rotary kiln kiln tail chute for the production of oxidation pelletizing. The utility model provides a rotary kiln kiln tail chute, including the chute bottom plate, locating the chute body on the chute bottom plate, the chute body is formed by prefabricated brick the building of polylith, and the prefabricated brick that lies in chute body top is equipped with buried bolt in advance to be connected with the chute bottom plate through buried bolt in advance. The utility model discloses a chute body top is connected with the chute bottom plate through buried bolt in advance, has better joint strength, avoids producing the brickwork joint because of washed away by hot -blast erosion and pellet at chute body top, can guarantee the top and not have the hot gas flow and get into the brick bottom, prevents the arch camber of the chute neck brick body, guarantees normal thermal regulation requirement, has longer life.
Description
Technical field
The utility model relates to a kind of rotary kiln chute, for the production of acid pellet.
Background technology
In the prior art, rotary kiln chute is usually directly built by laying bricks or stones by preformed bricks and is formed in chute bottom plate, and then surrounding cast-in-place high-strength castable shape is in aggregates.In the production process of acid pellet; rotary kiln chute corrodes by hot blast for a long time and pellet washes away; brickwork joint is produced gradually at chute top; a large amount of hot blast can enter bottom brick from the brickwork joint at chute top; cause the brick body on chute inclined-plane to build channel floor arch camber, bottom deformation by laying bricks or stones, affect heat supply duty, must process be shut down; affect pellet output, add the cost of overhaul.
Utility model content
Technical problem to be solved in the utility model is: the rotary kiln chute providing a kind of longer service life.
The technical scheme adopted for solving the problems of the technologies described above the utility model is: rotary kiln chute, comprise chute bottom plate, the chute body be located in chute bottom plate, chute body is built by laying bricks or stones by polylith preformed bricks and is formed, the preformed bricks being positioned at chute bodies top is provided with pre-embedded bolt, and is connected with chute bottom plate by pre-embedded bolt.
Further: before being positioned at chute bodies top, the preformed bricks of two rows is provided with pre-embedded bolt.
Further: the preformed bricks with pre-embedded bolt is also provided with rock wool layer between its bottom surface and chute bottom plate.
Further: preformed bricks is corundum brick.
The beneficial effects of the utility model are: chute bodies top is connected with chute bottom plate by pre-embedded bolt, there is better bonding strength, avoid because washing away by hot blast erosion and pellet and produce brickwork joint in chute bodies top for a long time, can ensure that top enters bottom brick without thermal current, prevent the arch camber of chute neck brick body, ensure normal thermal regulation requirement.The utility model can extend the service life of rotary kiln chute, and service life can reach more than 3 years, thus reduces the repair time, saves recondition expense, ensures the normal production time.
Accompanying drawing explanation
Fig. 1 is front schematic view of the present utility model;
Fig. 2 is side schematic view of the present utility model;
Parts, position and numbering in figure: 1-chute bottom plate, 2-chute body, 21-preformed bricks, 211-pre-embedded bolt, 3-rock wool layer, the high-strength castable of 4-.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model comprises chute bottom plate 1, the chute body 2 be located in chute bottom plate 1, chute body 2 is built by laying bricks or stones by polylith preformed bricks 21 and is formed, and the preformed bricks 21 being positioned at chute body 2 top is provided with pre-embedded bolt 211, and is connected with chute bottom plate 1 by pre-embedded bolt 211.
Preferably, before being positioned at chute body 2 top, the preformed bricks 21 of two rows is provided with pre-embedded bolt 211.If all preformed bricks 21 of chute body 2 all arrange pre-embedded bolt 211, correspondingly construct also more complicated, cost of manufacture is also higher, and only before chute body 2 top two row preformed bricks 21 pre-embedded bolt 211 is set, the problem of chute neck brick body arch camber can be solved, thus realize goal of the invention with less expensive reasonable manner.Usually two pre-embedded bolts 211 are set in every block preformed bricks 21.
Preferably, the preformed bricks 21 with pre-embedded bolt 211 is also provided with rock wool layer 3 between its bottom surface and chute bottom plate 1, ensures that preformed bricks 21 better contacts with chute bottom plate 1, makes syndeton tightr.Rock wool layer 3 thickness is generally 2mm ~ 3mm.
Preferably, preformed bricks 21 is corundum brick, can meet working condition requirement better.Chute bottom plate 1 generally adopts steel plate.
Embodiment:
Steel plate is adopted to make chute bottom plate 1, and relevant position processes the installing hole of pre-embedded bolt 211 in chute bottom plate 1, preformed bricks 21 is built in installation by laying bricks or stones, preformed bricks 21 adopts corundum brick, before being positioned at chute body 2 top, the preformed bricks 21 of two rows is provided with pre-embedded bolt 211, and be connected with chute bottom plate 1 by pre-embedded bolt 211, the preformed bricks 21 with pre-embedded bolt 211 is also provided with the thick rock wool layer of 2mm ~ 3mm 3 between its bottom surface and chute bottom plate 1, should make when building by laying bricks or stones to tamp with refractory wass between brickwork joint, ensure that flue gas must not be scurried into bottom brickwork joint and brick, to protect chute bottom plate 1 indeformable, prevent the arch camber of brick body.After all preformed bricks 21 install, surrounding adopts high-strength castable 4 to clog process.In actual use, after kiln hood heats up, owing to there is thermal expansion; also need at the outer wall of chute bottom plate 1 by pre-embedded bolt 211 fastening a time again; ensure that preformed bricks 21 better contacts with chute bottom plate 1, chute bottom plate 1 can better be protected, prevent the arch camber of brick body.
