Abstract

This utility model relates to a rotary kiln inner liner, which is mainly refer to a new rotary kiln inner liner that is used in cementrotary kiln. It is mainly comprised of internal cylinder body, looped type internal cylinder body support and Zr-Al cotton thermal insulation plate. Internal cylinder body is rolling welded by heat resistant steel board, on the external circumference surface of which, disposed several looped type supports being made of stripe shape heat resistant steel board and arranged in equidistance and along internal cylinder body center axle direction, and the plane that each looped type support lies in is vertical with the internal cylinder body center axle and each looped type support is integered with internal cylinder body by means of welding process. Zr-Al cotton thermal insulation plate is filling between the looped type internal cylinder body supports. In actual application, this kind of new inner liner is positioned between heat-resisting brick and kiln cylindrical body so as to form one thermal insulation layer and reach the double objective of this invention: both reducing energy-consumption and protection the overall equipment.

Description

A kind of novel rotary kiln liner

Technical field

The utility model relates to a kind of inner liner of rotary kiln, mainly refers to a kind of novel rotary kiln liner of using in the cement rotary kiln.

Background technology

In the Cement Production process, the present normally used capital equipment of producer, it is exactly cement rotary kiln, this cement rotary kiln mainly is made of kiln cylinder body and heat resisting brick, wherein kiln cylinder body is made by steel plate, the heat resisting brick brick work forms refractory layer in the inboard of kiln cylinder body, for good thermal environment is created in the generation of cement, yet, a large amount of practices show, the cement rotary kiln of this double-layer structure formula exists many deficiencies, as: though heat resisting brick is heat-resisting, the coefficient of heat conduction is bigger, in process of production, heat resisting brick can conduct by kiln cylinder body a large amount of heats in atmosphere, cause the loss of a large amount of energy, and the while is because of the conduction of heat resisting brick, the surface temperature of kiln cylinder body is raise greatly, quicken the chemical reaction velocity of oxygen and corrosive gas in kiln cylinder body steel plate and the air, also just quickened the damage progress of kiln cylinder body, caused unnecessary economic loss.

The utility model content

In view of this; the purpose of this utility model provides a kind of novel rotary kiln liner of the good heat-insulation effect easy to use of a kind of steel and zirconium aluminum wool thermal insulation thermal insulation board formation; cement rotary kiln after utilizing this novel rotary kiln liner repacking carries out in the process of manufacture of cement; reach the minimizing hear rate; improve output; the protection kiln cylinder body, the purpose of prolongation service life of equipment.

For solving the problems of the technologies described above, a kind of novel rotary kiln liner of the present utility model is made up of inner barrel, ring-like inner barrel support, zirconium aluminum wool thermal insulation thermal insulation board, inner barrel is welded by the heat-resisting steel sheet and plate rolling, cylindrical at inner barrel encloses on the face, be provided with the ring-like support that several are made by the stripe shape heat-resisting steel sheet and plate along the inner barrel axis direction, each plane, ring-like support place is all vertical with the inner barrel axle center, each ring-like support all is connected as a single entity by welding procedure and inner barrel, is filled with the thermal insulation thermal insulation board that the zirconium aluminum wool is made between ring-like support and ring-like support.

Owing to adopted such scheme: in the process of producing cement; heat in the cement rotary kiln is under the effect of the novel rotary kiln liner of steel and zirconium aluminum wool thermal insulation thermal insulation board composition; the speed that the interior heat of kiln outwards transmits has slowed down; temperature in the kiln tube is maintained; the surface temperature of kiln cylinder body obtains descending, thereby has reached the dual purpose of saving the energy and protection equipment.

Description of drawings

Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:

Fig. 1 is the utility model structural representation.

Rotary kiln section structure schematic diagram when Fig. 2 is the utility model use.

Rotary kiln partial cutaway schematic when Fig. 3 is the utility model use.

The specific embodiment

In Fig. 1,1, inner barrel 2, ring-like inner barrel support 3, zirconium aluminum wool thermal insulation thermal insulation board.

In Fig. 1, a kind of novel rotary kiln liner of the present utility model, constitute by inner barrel 1, ring-like inner barrel support 2, zirconium aluminum wool thermal insulation thermal insulation board 3, wherein: inner barrel 1 is by the thick heat-resisting steel sheet and plate rolling of 4mm and is welded, on the outer circumference surface of inner barrel 1, be uniform-distribution with the high 40mm that several are made by stripe shape heat resisting steel along the inner barrel axis direction, the ring-like inner barrel support 2 of thick 5mm, distance between ring-like inner barrel support and the ring-like inner barrel support is 150mm, adds the zirconium aluminum wool thermal insulation thermal insulation board that has 40mm thick between ring-like support and ring-like support.

In Fig. 2,1, kiln cylinder body 2, heat resisting brick 3, inner barrel 4, zirconium aluminum wool thermal insulation thermal insulation board.

In Fig. 2, when the cement rotary kiln diameter was 4m, cement rotary kiln its composition arrangement from inside to outside was followed successively by: the thick 160mm of heat resisting brick, the thick 5mm of inner barrel, the high 40mm of ring-like inner barrel support, zirconium aluminum wool insulation thickness of slab 40mm, the thick 40mm of kiln cylinder body, wherein: the thick 5mm of ring-like inner barrel support.

In Fig. 3,1, kiln cylinder body 2, heat resisting brick 3, inner barrel 4, ring-like inner barrel support 5, zirconium aluminum wool thermal insulation thermal insulation board.

The partial cutaway schematic of rotary kiln when Fig. 3 uses for the utility model; as can be seen from the figure; owing in kiln cylinder body, increased the novel rotary kiln liner of forming by inner barrel 3 ring-like inner barrel supports 4 and zirconium aluminum wool thermal insulation thermal insulation board 5; temperature in the kiln is protected; the speed that heat outwards transmits in the kiln that slowed down promptly can save energy and can also protect equipment.
