Abstract
The utility model relates to a double-coating preheater inner cylinder, which is used in a cyclone cylinder of a kiln tail preheater of a cement pre-decomposition system. The double-coating preheater inner cylinder comprises a cylinder and is characterized in that the cylinder body is enclosed by a plurality of base material frameworks, wherein both the inner surface and the outer surface of the cylinder body are provided with coatings; an inner connecting plate is arranged inside the base material frameworks in the coatings; an outer connecting plate is arranged outside the base material frameworks; the inner connecting plate, the base material frameworks and the outer connecting plate are provided with connecting holes formed in corresponding positions; bolts are connected in the connecting holes; and two sides of the bolts are connected with nuts for fixation. The double-coating preheater inner cylinder has the beneficial effects that the heat consumption of the pre-decomposition system is effectively reduced by the double-coating preheater inner cylinder, the energy consumption is reduced, the consumption of rare metal is reduced, the dust discharge is reduced, environmental protection is facilitated, the cylinder body has strong high temperature resistance, flushing resistance and corrosion resistance, the strength of the cylinder body is increased by the double coatings and a wear-resistant pipe is difficult to damage.
Description
Technical field
The utility model relates to a kind of pair of smear layer preheater inner barrel, is used in the whirlwind tube of kiln tail preheater of cement precalcining system.
Background technology
At present, the inner core of the kiln tail preheater whirlwind tube of cement precalcining system is owing to be operated in the environment of high temperature, high spurt, high corrosion; Usually adopt heat resisting steel to make; Because corrosion-resistant, the anti-scouring capability of heat resisting steel is poor, and cost is higher, makes that the inner core life cycle is shorter; Influence system's running rate, increased production cost.
The utility model content
According to the deficiency of above prior art, the utility model technical problem to be solved is: a kind of pair of smear layer preheater inner barrel is provided, have high temperature resistantly, anti-wash away, characteristics that corrosion resistance is strong, and easy for installation, cost is low.
The described a kind of pair of smear layer preheater inner barrel of the utility model comprises cylindrical shell, and cylindrical shell is centered on by a plurality of base material skeletons and forms; The inner surface and the outer surface of cylindrical shell are equipped with smear layer; Base material skeleton inboard in the smear layer is provided with interior connecting plate, and the base material skeleton outside is provided with outside link plate, and interior connecting plate, base material skeleton and outside link plate are provided with the corresponding connecting hole in position; Leading in the connecting hole has bolt, and bolt both sides attaching nut fixes.
Cylindrical shell around forming, for the whirlwind tube of different size, adopts the base material skeleton of varying number by a plurality of base material skeletons, has made things convenient for practical application.The inner surface and the outer surface of cylindrical shell are equipped with smear layer, can play a protective role to the base material skeleton, avoid wearing and tearing, and further strengthen the intensity of cylindrical shell.
Described base material cross-section of its skeleton shape is preferably circle, square, fan-shaped, flute profile, bar shaped or I-shaped.That the base material skeleton adopts is high temperature resistant, corrosion-resistant, anti-thermal shock, antiscour material are processed.
Described smear layer preferably adopts fire-resistant coating to process.
Connecting plate and outside link plate can be the loop configuration of integral type in described, connect for ease also or to organize straight plate structure for many group arcuate structures more.Interior connecting plate and outside link plate can only be arranged on an end of cylindrical shell, also can all be provided with at the two ends of cylindrical shell, or all are provided with in two ends, the centre of cylindrical shell, to increase the fastness that connects.
During use,, adopt the base material skeleton of varying number to form cylindrical shell according to the whirlwind tube of different size; Through interior connecting plate and outside link plate cylindrical shell is fixed subsequently; Smear on inside and outside surface at last smear layer is set, easy for installation, reduced labour intensity; Stability is high, and prolong service life greatly.
The beneficial effect that the utility model had is: two smear layer preheater inner barrels effectively reduce the hear rate of precalcining system; Reduce energy resource consumption, reduce the rare metal consumption, reduce dust emission; Be beneficial to environmental protection; Cylindrical shell is high temperature resistant, anti-ly wash away, corrosion resistance is strong, and two smear layers have increased cylinder strength, make the base material skeleton not fragile.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A view among Fig. 1;
Among the figure: 1, smear layer 2, outside link plate 3, base material skeleton 4, interior connecting plate 5, connecting hole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
As depicted in figs. 1 and 2, the described a kind of pair of smear layer preheater inner barrel of the utility model comprises cylindrical shell; Around forming, the inner surface of cylindrical shell and outer surface are equipped with smear layer 1 to cylindrical shell by a plurality of base material skeletons 3, connecting plate 4 in base material skeleton 3 inboards in the smear layer 1 are provided with; Base material skeleton 3 outsides are provided with outside link plate 2; Interior connecting plate 4, base material skeleton 3 and outside link plate 2 are provided with the corresponding connecting hole 5 in position, and leading in the connecting hole 5 has bolt, and bolt both sides attaching nut fixes.
Cylindrical shell around forming, for the whirlwind tube of different size, adopts the base material skeleton 3 of varying number by a plurality of base material skeletons 3, has made things convenient for practical application.The inner surface of cylindrical shell and outer surface are equipped with smear layer 1, can play a protective role to base material skeleton 3, avoid wearing and tearing, and further strengthen the intensity of cylindrical shell.
The shape of cross section of described base material skeleton 3 is circular.That base material skeleton 3 adopts is high temperature resistant, corrosion-resistant, anti-thermal shock, antiscour material are processed.
Described smear layer 1 adopts fire-resistant coating to process.
Connecting plate 4 is the loop configuration of integral type with outside link plate 2 in described.Interior connecting plate 4 is provided with the lower end of outside link plate 2 at cylindrical shell.
During use,, adopt the base material skeleton 3 of varying number to form cylindrical shell according to the whirlwind tube of different size; Fix with 2 pairs of cylindrical shells of outside link plate through interior connecting plate 4 subsequently; Smear on inside and outside surface at last smear layer 1 is set, easy for installation, reduced labour intensity; Stability is high, and prolong service life greatly.
Two smear layer preheater inner barrels effectively reduce the hear rate of precalcining system, reduce energy resource consumption, reduce the rare metal consumption; Reduce dust emission, be beneficial to environmental protection, cylindrical shell is high temperature resistant, anti-ly wash away, corrosion resistance is strong; Two smear layers 1 have increased cylinder strength, make base material skeleton 3 not fragile.
