Abstract
The utility model discloses an anti-felting anti-stop rotary ash discharge valve, comprising an impeller (1), a valve casing (2), a speed reducer (3), a motor (4), blades (5), a shaft (6), a shaft sleeve (7), a key (8) and an arc panel (9). The anti-felting anti-stop rotary ash discharge valve can successfully discharge materials and powder dust with finer grain diameter and larger viscosity, effectively preventing felting and stopping of the powder dust on the impeller. The anti-felting anti-stop rotary ash discharge valve not only is suitable for discharging ordinary dry non fibrous dust or the materials, but also is suitable for discharging the powder dust with larger viscosity and definite humidity. The utility model can be used for discharging various devices and the ash discharge devices of various dust removers of industries of metallurgy, mines, chemical engineering, coals, cement, electric power, machines, fireproofing materials, grains, etc.
Description
The utility model belongs to the improvement of the blade wheel structure of star revolution discharge mechanism.
Various valves are of many uses.The major function of revolution unloading valve of the present utility model is the dust in the container or material successfully to be arranged draw off and reduce bleeding of air.For ensureing the realization of these functions of turning round unloading valve, impeller performance is a key.
The blade of known star revolution unloading valve impeller is directly to be welded on the axle sleeve, or directly casts with axle sleeve.45 °～60 ° angle is arranged between blade and the blade, and the appearance material space that is constituted with shell between the blade is a flute profile.The unloading valve of this structure blade owing between the blade certain angle is arranged, has very big tension force and seizes power on both sides by the arms for the dust or the material that inject in it, easily forms the dust stratification dead band near root of blade.When revolution, because valve casing to the extruding of dust, makes dust near root of blade and axle sleeve connecting part be compacted and bonds on it.When the impeller lattice of filling dust were turned back to the bottom, outside dust unloaded, but the dust around impeller root and the axle sleeve forms bonding.The revolution that the revolution unloading valve goes round and begins again like this, impeller are stopped up by dust or material bonding from inside to outside gradually.At last, make whole impeller become a cylindrical body cylinder, thereby make unloading valve lose the function that row unloads dust or material.Less when the particle diameter of dust or material, proportion is lighter, and when viscosity was big, the bonded phenomenon of blocking of star revolution discharge valve was more obvious, and the cycle of appearance is shorter, and one month at most, a week will occur once at least.When star revolution unloading valve is stopped up by dust bonding, be valve body can be unloaded, bonding is blocked in dust between the blade with manually plucking out, and then installs and reuse.Even like this, the star of said structure revolution unloading valve has been continued to use decades, still uses in the whole nation at present.
The purpose of this utility model is: a kind of anti-stick, anti-plugging revolution unloading valve are provided, adopt the unloading valve of this new shape structure, not only kept original star to turn round the sealability of unloading valve, unload grey ability fully, its outstanding feature is to have prevented that effectively dust bonding is blocked on the impeller.
Unloading valve of the present utility model is of many uses, can be used for the discharging of various device of industries such as metallurgy, mine, chemical industry, coal, cement, electric power, machinery, refractory material and grain and the ash-exhausting device of various dedusters.This unloading valve is applicable to that not only the row of small granular dust unloads; But also the row who is applicable to powdery dust and dust unloads; The row who not only is applicable to dry non-fiber dust unloads, but also the row of the big dust of particularly suitable viscosity unloads.
The utility model provides a kind of novel impeller structure, and this impeller is that the angle adds a cambered plate between blade and blade, and cambered plate is tangent line with blade and is connected, and perhaps 4～8 cambered plate phase backing run systems is formed.Not having angle between the impeller of this structure, the blade, is cambered plate between blade and the blade, and this is very little to the tension force of dust and the power of seizing on both sides by the arms, no dust stratification dead band, and when below the impeller grid that is full of dust is turned back to, dust unloads automatically.Therefore, dust or material are to the non-caked obstruction of blade, and impeller can successfully unload dust or material, thereby have guaranteed the normal operation of revolution unloading valve.
A concrete structure example of the present utility model is provided by accompanying drawing.
Here the gyrostat unloading valve that to provide an impeller be four blades.This valve mainly comprises: impeller ［ 1 ］, valve casing ［ 2 ］, speed reducer ［ 3 ］, motor ［ 4 ］, blade ［ 5 ］, axle ［ 6 ］, axle sleeve ［ 7 ］, key ［ 8 ］, cambered plate compositions such as ［ 9 ］.
The material of impeller ［ 1 ］ can select for use steel, cast iron or other Metal Material Weldings or casting to form.The structure of impeller ［ 1 ］ as shown in the figure.Be connected with a cambered plate ［ 9 ］ between blade ［ 5 ］ and the blade ［ 5 ］, cambered plate ［ 9 ］ is tangent or not tangent with blade ［ 5 ］ and is connected, and this example is tangent connection.Blade ［ 5 ］, cambered plate ［ 9 ］ are the camber line of concavity with the cross-sectional configuration that blade ［ 5 ］ is constituted, and parabola or sphere wire, this example are arc shaped.Impeller ［ 1 ］ radius is R, and the summit of cambered plate ［ 9 ］ is 1/4～1/2 of impeller ［ a 1 ］ radius to the distance of axis, and this example adopts 1/3R, and the radius of cambered plate ［ 9 ］ is 2/3R.To the cast iron impeller, the shot-peening polishing is wanted on the surface of its blade ［ 5 ］, cambered plate ［ 9 ］; To the impeller of welded steel plate, weld seam adopts downhand welding, and the postwelding weld seam will polish polishing.
Other parts of this unloading valve are manufactured by former star revolution unloading valve.
Impeller is by motoring, and wheel speed is 20～45 rev/mins by electric motor drive after speed reducer slows down, and this example is 24 rev/mins.When impeller turned round, the space that blade up, cambered plate and valve casing are formed fell into and is full of dust, and row down unloads dust.The sealing of the anti-revolution of this anti-stick unloading valve is the same with conventional star revolution unloading valve, to the bigger container of negative pressure by blade with fill ash and seal, owing to blade and valve casing in the textural certain clearance that needs, depending merely on blade can not be tight-closed.So, in operation, need to be equipped with the ash envelope.For this reason, this unloading valve when operation with conventional unloading valve is the same should be the dust emptying, the ash envelope that need keep certain height, its ash envelope height should be by the negative pressure decision of deduster; Can arrange for the less container of negative pressure, material or dust and to unstow, the air leak rate of air curtain of this unloading valve is less than 0.1%.
