Abstract
The utility model relates to a novel dry-process rotary cement kiln triple air brake valve plate. The novel dry-process rotary cement kiln triple air brake valve plate comprises a valve plate body, wherein the cross section of the valve plate body is formed by four edges, three of the four edges are straight lines and the rest is an arc line, an ear is arranged in the straight line opposite to the arc line, and corundum-mullite-zirconia castable are adopted in the valve plate body. The novel dry-process rotary cement kiln triple air brake valve plate is not prone to spalling, abrasion-resistant and washing-resistant.
Description
Technical field
The utility model relates to a kind of valve plate, is specifically related to a kind of new type nonaqueous cement rotary kiln air lock valve plate.
Background technique
Tertiary air valve is mainly that also can guarantee in rotary kiln has the adequate ventilation amount, makes it the key equipment that both keep Proper Match by regulating the aperture of tertiary air valve, can guaranteeing decomposing furnace coal burning requisite oxygen content in new dry process rotary kiln.Traditional tertiary air valve average life can only be with about 6 months, and particular problem has: 1. framework deformation is stuck, and 2. the castable bulk is peeled off, 3. outside material explosion.After the valve plate deformed damaged, can't regulate the air quantity of tertiary air, inconvenience is regulated in the system operation, badly influences kiln system output and quality.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of high quality is provided, incrust, wear-resisting, the new type nonaqueous cement rotary kiln tertiary air gate valve plate of resistance to erosion.
Technological scheme: in order to solve the problems of the technologies described above, a kind of new type nonaqueous cement rotary kiln tertiary air gate valve plate described in the utility model, it comprises the valve plate body, the cross section of described valve plate body is comprised of four edges, wherein three limits are straight line, an other limit is camber line, at described camber line, on relative straight line, is provided with hanger, and described valve plate body adopts the corundum-mullite castable.
Described valve plate body is formed in one.
Described hanger arranges in pairs.
The height of described valve plate body is between 1.5-3m.
The width of described valve plate body is between 1-2.5m.
The thickness of described valve plate body is between 150-350mm.
The first molding of the utility model, and be equipped with corresponding refractory steel, after carrying out special soldering, this skeleton at high temperature is not easy distortion, thereby has solved stuck problem; The special castable refractory that to add by corundum, mullite and powder that some are special on skeleton be main raw material again, this castable only has at a certain temperature just can give full play to its effect, between material and material, closely fill, corresponding chemical effect occurs under given conditions, make the variation of internal structure generation matter, pass through again special baking, thereby castable and refractory steel skeleton are closely bonded, form whole.
Beneficial effect: compared with prior art, its remarkable advantage is the utility model: the utility model overall structure is simple, through overbaking, the inside and outside material of valve plate closely bonds, and variation that can Yin Wendu and producing is peeled off and explosion, in use, wear-resisting, resistance to erosion, quality is higher.
The accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model.
Wherein:
1, valve plate body; 2, hanger
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, a kind of new type nonaqueous cement rotary kiln tertiary air gate valve plate described in the utility model, it comprises valve plate body 1, the cross section of described valve plate body 1 is comprised of four edges, wherein three limits are straight line, an other limit is camber line, at described camber line, on relative straight line, is provided with hanger 2, and described valve plate body 1 adopts the corundum-mullite castable; Described valve plate body 1 is formed in one; Described hanger 2 arranges in pairs; The height of described valve plate body 1 is between 1.5-3m; The width of described valve plate body 1 is between 1-2.5m; The thickness of described valve plate body 1 is between 150-350mm.The utility model overall structure is simple, and through overbaking, the inside and outside material of valve plate closely bonds, and variation that can Yin Wendu and producing is peeled off and explosion, in use, wear-resisting, resistance to erosion, and quality is higher.
The utility model provides a kind of thinking and method; method and the approach of this technological scheme of specific implementation are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications; these improvements and modifications also should be considered as protection domain of the present utility model, in the present embodiment not clear and definite each constituent element all available prior art realized.
