Abstract
The utility model relates to a high-temperature novel wear-resistant valve plate for a tertiary air pipe, which comprises a valve plate body, wherein the valve plate body can be square or adopt the structure that the rear end is square and the front end is semicircular; a welded double-layered heat-resisting steel reinforcement frame is arranged inside the valve plate body and is provided with a plurality of cramps which are distributed in a manner of being increased from the rear end to the front end of the valve plate body, wherein the directions of the cramps are different; more than two liftinglugs are arranged on the valve plate body and are fixed through a reinforcing plate; the liftinglugs are connected together with the heat-resisting steel reinforcement frame; and a coating is arranged at the periphery of the valve plate. The high-temperature novel wear-resistant valve plate for the tertiary air pipe is used on a tertiary air pipe lifting type hand-operated or electric gate valve of a novel dry-process cement rotary kiln; the product is high in strength, wear-resistant, and good in mechanical shock resistance, has an excellent anti-stripping and anti-cracking performance, is long in service life and convenient in construction; and external wear-resistant material and internal heat-resisting steel reinforcement are bonded tightly and hamper each other, so that the practicability of the product is ensured.
Description
Technical field:
The utility model relates to the cement industry fire resisting material field, in particular, relates to a kind of tertiary-air pipe high temperature novel wear resistant valve plate, is applicable to that new type nonaqueous cement rotary kiln tertiary-air pipe hoisting type is manually or on the electric gate valve.
Background technology:
The tertiary-air pipe valve plate waters into system's visual plant as the cement plant, mainly is used in the kiln with air quantity and the interior balance with air quantity of stove, in real process; The tertiary-air pipe valve plate will receive for a long time that 1000 ℃ of left and right sides high temperature is chloride, the erosive wear of alkali harmful components, dusty gas; According to dry-process cement rotary kiln thermal technology characteristics, its tertiary-air pipe valve plate generally adopts heat resisting steel external upset (EU) pours to process, and therefore exists the valve plate pours to be prone to peel off in actual use; The whole oxidations of exposed parts; Burn, it is interior with air quantity and the interior balance with air quantity of stove to make it lose kiln, brings bigger negative effect for the stability of whole system.The life-span of therefore present tertiary-air pipe valve plate is short, maintenance is many, influence actual conditions urgent need such as running rate will improve.
The utility model content:
The purpose of the utility model is the weak point to prior art, and a kind of tertiary-air pipe high temperature novel wear resistant valve plate is provided, and its product strength is high; Wear-resistant, mechanical shock resistance is good, has good anti-strip property and splitting resistance; Long service life; And easy construction, safe and reliable, shortened the construction period greatly.
The technological solution of the utility model is following:
Tertiary-air pipe high temperature novel wear resistant valve plate, it comprises the valve plate body, and said valve plate body has two kinds of structures, and a kind of valve plate body is square, and the rear end of another kind of valve plate body is square, front end is semicircle; The inside of said valve plate body is provided with the heat-resisting reinforced frame of the bilayer that is welded; Be welded with a plurality of palladium nails on the said heat-resisting reinforced frame, the distribution of said palladium nail is to increase gradually to front end from the rear end of valve plate body, and the direction of each palladium nail has nothing in common with each other.
In the technique scheme, said valve plate body is provided with plural hanger, and fixes through a gusset plate.
In the technique scheme, said hanger and described heat-resisting reinforced frame are welded together.
In the technique scheme, be provided with one deck coating around the said valve plate.
The beneficial effect of the utility model is:
Add corundum, electrofused mullite, superfine bauxite aggregate and special high-abrasive material in its castable refractory of valve plate body of the utility model, and add the special-purpose special additive of certain proportion quantity, ramming vibration moulding; And double-deck wear-resisting reinforcing bar and castable refractory in the valve plate body closely bond, and the palladium that increases gradually to front end from the rear end of valve plate body of a plurality of distributions of welding on the heat-resisting reinforced frame follows closely and make valve plate body bulk strength higher, and bond stress is bigger; And, therefore having globality preferably through prebake conditions, it is wear-resistant; Mechanical shock resistance is good; Have good anti-strip property and splitting resistance, long service life, and easy construction; Safe and reliable, shortened the construction period greatly.The utility model can be processed difformity, size according to requirement of client simultaneously, satisfies client's demand.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is another structural representation of the utility model.
The specific embodiment:
Embodiment 1, sees accompanying drawing 1, tertiary-air pipe high temperature novel wear resistant valve plate, and it comprises valve plate body 1, and valve plate body wadding material is the high-strength wearable material, and the rear end of said valve plate body is square, and front end is semicircle; The inside of said valve plate body is provided with the heat-resisting reinforced frame 2 of the bilayer that is welded; Be welded with a plurality of palladium nails 3 on the said heat-resisting reinforced frame; The distribution of said palladium nail is to increase gradually to front end from the rear end of valve plate body; And the direction of each palladium nail has nothing in common with each other, and has increased the bond stress between heat-resisting reinforced frame and the high-strength wearable material like this, makes whole valve plate body intensity high; Mechanical shock resistance is good, long service life.
Said valve plate body is provided with two hangers 4, and fixing through a gusset plate 5, is convenient to transportation and the valve plate body is installed.
Said hanger and described heat-resisting reinforced frame are welded together, and hanger lower end and wear-resistant castable closely bond together its firm and durable.
Be provided with one deck coating around the said valve plate, be convenient to attractive in appearance.
The utility model can use separately in tertiary-air pipe; Also can earlier valve plate special precast brick be laid in the tertiary-air pipe both sides; Again with the supporting use of tertiary-air pipe high temperature novel wear resistant valve plate; The air quantity centrality is optimized like this, has reduced the wearing and tearing that cause because of air quantity is excessive the valve body both sides, the service life that helps to improve the tertiary air valve plate.
