Abstract
The utility model discloses a cement square kiln for calcining porous raw material blocks, which comprises a kiln casing (1), a kiln inner core (3), a fireproof layer (2), a fume cover (4) and a crushing unloading device (9), wherein the crushing unloading device (9) is positioned below a kiln body and above a chute (8), and the fireproof layer (2) and the kiln inner core (3) are positioned in the kiln casing. The structure is characterized in that the kiln inner core (3) is formed by piling up a plurality of square cement raw material blocks (5), and a plurality of holes are arranged on each square cement raw material block (5). Because the holes are arranged on the raw material blocks (5), ventilation and heat transmission functions are good during heating and burning time so as to cause the raw material blocks (5) to be uniformly and fully calcined without a large ventilating cooling rotary device and easily controlled. The utility model has the advantages of multiple holes of the raw material blocks, fast crash and unloading, and high productive efficiency.
Description
Technical field
The utility model relates to a kind of calcining cement kiln, especially a kind of high-efficiency and energy-saving type calcining cement rectangular kiln.
Background technology
At present, the stove calcining is mostly adopted in the manufacturing of cement, and stove calcining divides traditional circle to add water in advance to become raw material ball shaft kiln calcination and the calcining of dry method raw material powder rotary kiln, but also there are a little problems in this dual mode, first kind of traditional circle adds water in advance and becomes the calcining of raw material ball stove, though between the cement raw meal nodule accumulation gap is arranged in the kiln, but because raw material ball itself is an entity, and contain higher moisture content, therefore, the stove size is restricted, need relatively large air blast forced ventilation, and also easy generation limit wind is big, fiery partially, the problem of bad controls such as the uneven and easy caking of temperature; The second kind of main employing of dry method raw material powder rotation stove calcining convection current, radiant heat transfer is lower than the conduction heat transfer thermal efficiency; Need equipment such as large-scale electric cleaner, cooler; Whole round kiln body otherwise stop rotation, power consumption is big; It is big that one-time investment is wanted, and just can reach scale and benefit.
Summary of the invention
Problem at above-mentioned two kinds of calcining cement kilns existence, the utility model provides a kind of and has not needed large-scale ventilation cooling slewing, and is easy to control, and scale is changeable, invest less relatively, the semidry method preformed porous raw material piece calcining cement rectangular kiln that efficient is high again.
The utility model is to solve the problems of the technologies described above purpose like this, it comprises kiln hood, kiln inner core, flame retardant coating, petticoat pipe, broken blanking device, described petticoat pipe is positioned at the kiln top, broken blanking device is below the kiln and between above the chute, flame retardant coating and kiln inner core are positioned at kiln hood, its design feature is: described kiln inner core is built mutually by several square cement slurry pieces and is formed, and each square cement slurry piece is provided with a plurality of holes.
In order to solve the problems of the technologies described above better, each square cement slurry piece of the utility model kiln inner core is provided with evenly spaced each other longitudinal hole, or/and be provided with thereon with longitudinal hole from mutual evenly spaced cross through hole, be provided with many supporting girder steels parallel to each other below broken blanking device, every supporting girder steel is provided with many gang saws tooth.
The utility model is because elder generation's half-dry type raw material piece is provided with a lot of through holes, and the raw material piece is built into mutually and is the kiln inner core, when heating flame, having good ventilation conducts heat, thereby do not need large-scale ventilation cooling slewing, just can make its raw material piece calcining evenly fully, and be easy to control; Be that raw material piece hole is many again, broken blanking is fast, the production efficiency height.
Description of drawings
Fig. 1 is a perspective view of the present utility model,
Fig. 2 is the A-A sectional structure enlarged diagram of Fig. 1.In the drawings, 1, kiln hood 2, flame retardant coating 3, kiln inner core 4, petticoat pipe 5, raw material piece 6, thermometer hole 7, separate expanded metal lath 8, chute 9, broken blanking device 10, sawtooth 11, supporting girder steel 12, rotating shaft 13, power rotating disk
The specific embodiment
In Fig. 1 and Fig. 2, porous raw material piece 5 is square, its calcining cement kiln also is square, it comprises heat-resisting steel kiln hood 1, kiln inner core 3, flame retardant coating 2, petticoat pipe 4, broken blanking device 9, described petticoat pipe 4 is built mutually with refractory material by steel plate and is formed, it is positioned at the kiln top, fixing by the crane gear supporting, broken blanking device 9 comprises power rotating disk 13, rotating shaft 12, supporting girder steel 11, it is below the kiln body and between above the chute 8, supporting girder steel 11 is parallel to each other and is positioned at below the separate mesh expanded metals 7, supporting girder steel 11 is provided with 2-4 gang saw tooth 10, rotating shaft 12 is positioned at below the supporting girder steel 11, flame retardant coating 2 is built in kiln hood 1 inboard, thickness is the 100-200 millimeter, kiln inner core 3 is positioned at kiln hood 1 flame retardant coating 2, it is built mutually mutually by some identical shaped raw material pieces 5 and forms, cement slurry piece 5 is square, each square cement slurry piece 5 is provided with the longitudinal hole of two row, three row, the aperture is the 20-50 millimeter, also can be provided with the cross through hole that triplex row three is listed as by cement slurry piece 5, and the aperture is the 20-50 millimeter, or be provided with the longitudinal hole of two row, three row and the cross through hole of triplex row two row simultaneously, be parallel to each other between through hole and the through hole at interval or staggered interval; On vertical four shells of kiln body, also respectively be provided with 6-9 thermometer hole 6, in its hole thermocouple be housed, also be furnished with the insulation cover plate, below the rotating shaft 12 of broken blanking device 9, be connected with chute 8, be provided with at kiln body lower surface and separate expanded metal lath 7 at the upper surface of kiln body.After shove charge finishes, igniting, suitably force ventilation, the fuel in its raw material piece 5 is fully calcined rapidly; After being sintered into the clinker piece, start broken blanking device 9, commentaries on classics is executed in rotating shaft 12 front and back on the broken blanking device 9, drives supporting girder steel 11 and swings, and makes the sawtooth 10 on its supporting girder steel 11 that the cement slurry piece is broken into the powder shape, enters output in the chute 8.
