Abstract
The utility model discloses a long-life cone-shaped distributor, belonging to the technical field of powdery material distributors. The prior various distributors have the disadvantages of unreasonable structure, large resistance loss, small coal conveying capacity, large distributing errors, easy abrasion, and little possibility of disassembly, and have the disadvantage that the distributors are not suitable for coal spraying of large-sized blast furnaces. A truncated cone outer flange, an inner flange, a V-shaped distributing cover, and a trumpet-shaped distributing seat which are arranged on the utility model are connected to form integration by screws and bolts; a plurality of through holes are homogeneously distributed on the cone surface of the truncated cone outer flange in a same angle; composite distributing nozzles are welded on each of the through holes, and thereby, coal powder can be homogeneously distributed in the distributor. Transition and partial abrasion can not be generated in the nozzle. Distributing precision can be increased. The utility model is particularly suitable for the coal spraying of the large-sized blast furnaces.
Description
The utility model belongs to pulverulent material divider field.Be specially adapted to the distribution device of pulverized coal injection in blast furnace.
The divider that present China medium and small blast furnace coal injection is used is bottle formula or cutter formula divider (No. 3204942 patents of the U.S. or Chinese CN2038600U patent).These dividers are because of unreasonable structure, and resistance is decreased high, and defeated coal ability is little, and the quantity of dispensing branch is restricted, and coal dust distributes error big, incompatibility large blast furnace coal injection.Large blast furnace still is the multitube road blast furnace blowing system that falls behind so far, and its reason mainly is that divider does not pass a test.Anshan Iron and Steel Company brings into use nozzle-type pulverized coal distributor (patent publication No. CN2056420U) nineteen ninety, and the coal dust assignment accuracy increases, and distribution nozzle quantity increases.But because of structure is limit, incompatible big air quantity big coal injection amount, Anshan iron and steel plant uses the result, and the life-span of divider is not high, and distributer nozzle and distributing ring be quick-wearing very.
The purpose of this utility model is that a kind of improved long-lived conical distributor will be provided.It can distribute pulverulent material effectively, and distribution capability is big, precision is high, has longevity, is easy to the part changing and adjust.
Accompanying drawing 1 is long-lived conical distributor synoptic diagram.［ 1 ］ is nozzle among the figure, the nozzle cage that make for antifriction cast iron ［ 2 ］, and ［ 3 ］ are nozzle holder, ［ 4 ］ are the frustum outward flange, ［ 5 ］ be the frustum inside flange, ［ 6 ］ distribute lid for V-arrangement, and ［ 7 ］ are tubaeform dispense font, ［ 8 ］ be flange, ［ 9 ］ are screw, and ［ 10 ］ are attachment bolt.
Frustum outward flange ［ 4 ］, frustum inner flange ［ 5 ］, V-arrangement distribute lid ［ 6 ］ and tubaeform dispense font ［ 7 ］ to be connected by screw ［ 9 ］ and bolt ［ 10 ］ and form one, on the conical surface of frustum outward flange ［ 4 ］ with the same even angle some through holes (number of openings can design arbitrarily as required) that distribute, at the compound distributing nozzle of each through hole welding. Compound distribution Nozzle is made up of nozzle ［ 1 ］, nozzle cage ［ 2 ］ and nozzle carrier ［ 3 ］, adopts thread connection. V-arrangement distributes lid and tubaeform dispense font working face sprayed wc high-abrasive material. ［ 8 ］ connect pulverized coal preparation system conveyance conduit flange. Each part of the utility model is common straightcarbon steel except indicating material.
The utility model is achieved in that the coal dust (or Dual-Phrase Distribution of Gas olid) that enters divider, form uniform umbrella shape stream, Dual-Phrase Distribution of Gas olid and umbrella shape stream has guaranteed that the air-flow that is assigned with is reasonable, even point-blank in the compound distribution nozzle, and divider is not subjected to directly wearing and tearing and realizes longevity.Tubaeform dispense font ［ 7 ］ medullary ray and V-arrangement distribute lid ［ 6 ］ to be assembled on the coaxial centerlines.
When using the utility model divider, the flange ［ 8 ］ below distributor socket ［ 7 ］ links with the pulverized coal preparation system delivery manifold.Distributer nozzle ［ 1 ］ links with the coal jetting branch that leads to each air port of blast furnace.The coal dust that transports (or Dual-Phrase Distribution of Gas olid) enters in the divider, after nozzle ［ 1 ］ leads to each defeated coal arm of blast furnace, is sprayed into blast furnace by its distributed uniform equably.Above-mentioned ［ 1 ］～［ 7 ］ part is precision work and forms, and scale error is very little between each part, so distribute error (each branch injecting coal quantity accounts for the latter's percentage with the difference of average injecting coal quantity) to reach below 3% between the defeated coal arm in each air port.Two phase flow flows to rationally in the divider, does not produce turnover and concentrated wear at compound distribution nozzle place, and the divider life-span is prolonged.This outer nozzle, dispense font all adopt screw thread, Bolt Connection, be easy to change and adjust, and compound distribution nozzle easy accessibility, and wear-resisting, V-arrangement distributes lid also can dismantle easy access at any time.
The utility model divider compared with prior art, more reasonable structure, easily processing, nozzle does not does not wear and tear, the divider life-span prolongs, and is easy to change and maintenance, distribution capability is big, the precision height is applicable to the operation of the big air quantity big coal injection of large blast furnace amount.
Claims (3)
1, a kind of long-lived conical distributor, it is characterized in that frustum outward flange, frustum inside flange, V-arrangement distribute lid and tubaeform dispense font to form one by screw and Bolt Connection, on the conical surface of frustum outward flange with same even angle some through holes that distribute, the compound distribution nozzle of welding on each through hole.
2, according to the described divider of claim 1, it is characterized in that said compound distribution nozzle is made up of nozzle, nozzle cage and nozzle holder, adopt thread connection.
