Abstract
The utility model discloses a cyclone inner barrel of a preheater at the tail end of a kiln. The inner barrel is suspended on a top cover of a cyclone through a bracket, and the inner barrel is embedded and occluded with the cyclone by arc hangers; the hangers are steel hangers which comprise upper hangers, middle hangers and lower hangers; the upper hangers are inverted T-shaped and hung on the bracket at intervals; the middle hangers are horizontal H-shaped and form an inner barrel body through embedding and occluding with each other; the middle hanger at the top end of the inner barrel body is hung on the upper hanger and is embedded and occluded with the upper hanger mutually; the lower hangers are T-shaped, hung on the middle hangers at the bottom end of the inner barrel body and embedded and occluded with the middle hangers mutually; a circumferential locking device is arranged at the bottom end of the inner barrel; and a radial limit structure is arranged on the hanger. The cyclone inner barrel of the preheater at the tail end of the kiln has the advantages of simple structure, convenience in installation and replacement, light weight, low cost, good using effect and long service life.
Description
Technical field
The utility model belongs to the cement industry manufacturing field of equipment, particularly a kind of kiln tail preheater whirlwind tube inner core.
Background technology
In the predecomposition cement produced with the dry method is produced, the separative efficiency of gas material in preheater, inner core decisive role, and the advance of inner tube structure pattern and security reliability, to the result of use and even service life of inner core all be vital.
The inner core in the kiln tail preheater whirlwind tube mainly contains three kinds of structural shapes in the manufacture of cement at present: integral plate structure, strip casting lacing film and S mold casting lacing film.The thermal deformation of integral plate structure is big, and service life is short, and changes very difficulty; Strip casting lacing film casting deflection is big, and lacing film gap deviation is big, influences result of use and life-span; S mold casting lacing film structure is comparatively speaking laid particular stress on, and the heat resisting steel of consumption is on the high side, and the manufacturing cost of equipment is higher.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, change convenient, safe and reliable, distortion is little, in light weight, low cost of manufacture and result of use is good, the life-span is grown kiln tail preheater whirlwind tube inner core.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of kiln tail preheater whirlwind tube inner core; Said inner core is suspended on the whirlwind tube top cover through support; And inlay the interlock connection each other by the arc lacing film and form; Said lacing film is the steel lacing film, and said steel lacing film comprises slice, middle sheet and following sheet;
Said last slice be " ⊥ " shape, the compartment of terrain hangs on the said support;
Sheet is I-shaped in said, inlay interlock each other and form the inner core body, in said inner core body top said sheet hang over said last slice on, and with said last slice inlay interlock each other;
Said sheet down is " T " shape, hangs on the said middle sheet of said inner core body bottom, and inlays interlock each other with said middle sheet;
Said inner core bottom is provided with circumferential locking device;
Said lacing film is provided with radially position limiting structure.
Said circumferential locking device is a circumferential stay, and said circumferential stay is arranged in the hook, and said hook is arranged on the said surperficial bottom of sheet down,
The two ends of said stay are affixed with the said middle sheet of this time sheet both sides respectively.
Said radially position limiting structure is the radially positive stop lug boss that is arranged on the said lacing film both side surface, and said positive stop lug boss is positioned at the end that said lacing film is inlayed the interlock position.
Advantage and the good effect that the utlity model has are: the inner core lacing film adopts steel material, suspended structure, and individual construction is simple, is out of shape little in light weightly, and versatility is good; Form a complete inner core through inlaying interlock each other between the lacing film; The mutual load-bearing of lacing film self is reserved expansion gap between sheet and the sheet, thermal expansion distortion is had good compensatory; Radially position limiting structure and circumferential locking device are set simultaneously, can keep good whole rigidity.
In sum, the utility model is simple in structure, and installing and replacing is convenient, and in light weight, cost is low, and result of use is good, and the life-span is long.

The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1～Figure 10; A kind of kiln tail preheater whirlwind tube inner core, said inner core is suspended on the whirlwind tube top cover through support 4, and inlays the interlock connection each other by the arc lacing film and form; Said lacing film is the steel lacing film, and said steel lacing film comprises slice 1, middle sheet 2 and following sheet 3;
Said last slice 1 be " ⊥ " shape, the compartment of terrain hangs on the said support 4;
Said sheet 3 down is " T " shape, hangs on the said middle sheet 2 of said inner core body bottom, and inlays interlock each other with said middle sheet 2;
The said surperficial bottom of sheet down is provided with hook 7, is provided with circumferential stay 5 in the said hook 7, and the two ends of said circumferential stay 5 are affixed with the said middle sheet 2 of this time sheet both sides respectively;
The surface of said lacing film both sides is provided with radially positive stop lug boss 6, and said positive stop lug boss 6 is positioned at the end that lacing film is inlayed the interlock position.
Adopt the above-mentioned standard lacing film of different in width, different radians can form the inner core of different size.
The utility model adopts between the lacing film inlays interlock each other; Forming the inner core of different-diameter, differing heights, be used for preheater windspout barrel, is the critical component of preheater; Realize the function that material separates with hot blast in the whirlwind tube, improved the heat exchange efficiency of pre-heating system; Both had good thermal compensation property, and can keep good whole rigidity again, be suitable for the environment for use of preheating predecomposition cement produced with the dry method preheater.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the utility model.
