Abstract
The utility model belongs to the field of coal powder gas conveying for iron making sinter. The utility model is especially suitable for the pulverized coal distributor device of a sintering machine igniter. The upper end of the intake chamber is provided with a distributing plate, the upper end of the distributing plate is provided with a plurality of distributing branch tubes, and the lower part of the center of the distributing plate is provided with a distributing cone. The distributing plate, the distributing cone and the intake chamber are all arranged on the same central axis. The central axis of each distributing branch tube and the central axis of the distributing cone are formed an included angle less than 30DEG. C. Compared with the prior art, the utility model has the advantages of simple structure, easy producing and easy replacement.
Description
The present utility model belongs to ironmaking and sintering coal dust material gas transportation art.Be specially adapted to the pulverized coal distributor device of blast-furnace tuyere and ignition of sintering process device.
In the prior art field of pulverized coal distributor, China is early stage, and what adopt is a bottle formula pulverized coal distributor, and this distributor in use has a lot of shortcomings, and most importantly it distribute error big, and it is big to be transferred the material drag losses, is therefore now eliminated gradually.Announced " pulverized coal injection in blast furnace distributor " (a 88204417.6) patent Chinese patent literature in 1988, the distributor of document introduction is a kind of cutter formula distributor, though assignment accuracy is higher, but it is bigger that this distributor is made difficulty of processing, the arm radical that coal dust distributes is few, generally can only be used for the less medium and small blast furnace in air port.Therefore this pulverized coal distributor is restricted in the use.
The purpose of this utility model is that proposition is a kind of simple in structure, and coal dust assignment accuracy height and replacing easy to manufacture be the bevel-type pulverized coal distributor easily.
According to the purpose of this utility model, the bevel-type pulverized coal distributor that we proposed, its operation principle is that the formed two-phase air-flow of coal dust and carrier gas is to enter in the distribution cavity from the air chamber bottom, by the awl of the distribution in the distribution cavity garden columnar airflow coal dust is divided into the annular airflow coal dust equably again, after the air-flow coal dust is transported to distribution plate equably, then equably the air-flow coal dust is assigned in each dispensing branch, finishes uniform distribution and pulverized coal conveying work by distribution plate.Enter the coal dust amount of each dispensing branch and be directly proportional, be inversely proportional to the resistance coefficient of arm with the sectional area of arm separately.When every arm of needs all obtained the coal dust of isodose, the material that only needs every arm is made identical shaped, size, cross section and the identical resistance coefficient of employing just reached necessary requirement.When obtaining specific (special) requirements coal dust amount, just can realize designing requirement as long as change the cross section of these dispensing branch as the indivedual dispensing branch of needs.
Be described in detail as followsly below according to the utility model accompanying drawing, 1 is dispensing branch in the accompanying drawings, and 2 for distributing awl, and 3 is distribution plate, and 4 is inlet plenum.The composition of this pulverized coal distributor be equipped with in the lower end of inlet plenum 4 one with the following joining ring flange of pipe, in inlet plenum 4 upper ends distribution plate 3 is housed, distribution awl 2 is housed in center, distribution plate 3 lower surface, distributes awl 2, distribution plate 3 and inlet plenum 4 to be installed on the same central axis.Distribute the tapering of the work light face cone body of awl 2 to answer≤60 ℃.On same garden, the upper surface week of distribution plate 3, some dispensing branch 1 evenly are installed, total radical of dispensing branch 1 can be decided according to designing requirement, but the central axis that every dispensing branch 1 is installed must and distribute the angle between the central axis of awl 2, distribution plate 3 and inlet plenum 4 should≤30 ℃.And the distance between every dispensing branch 1 and the adjacent dispensing branch 1 is less than 10mm.Dispensing branch 1 and distribution awl 2 all are vulnerable parts in the utility model distributor, should adopt the anti-abrasive material manufacturing, therefore to consider the replacing of this class part, thus they with distribution plate between to connect can be thread connection, also can adopt other method to connect.
The utility model pulverized coal distributor has simple in structure compared with prior art, and easily manufactured, its vulnerable part is easy to change characteristics such as coal dust assignment accuracy height.Be to adopt dispensing branch 1 tightening the installation of solid matter row same garden week in addition on the distribution plate in this pulverized coal distributor 3, distributing awl 2 is again the middle room that occupies distribution plate 3 to greatest extent, therefore the wearing and tearing of eddy current He each parts of distribution cavity inside have been reduced, the resistance of inner skeleton is reduced, also reduced weight of equipment.
Claims (3)
1, a kind of pulverized coal distributor, the composition of this distributor be equipped with in the lower end of inlet plenum (4) one with the following joining ring flange of pipe, in the upper end of inlet plenum (4) distribution plate (3) is housed, dispensing branch (1) is housed on distribution plate (3) and distributes awl (2), it is characterized in that in distribution plate (3) center, lower surface distribution being installed bores (2), distribute awl (2), distribution plate (3) and inlet plenum (4) to be mounted on the same central axis, some dispensing branch (1) evenly were installed on same garden, the upper surface week of distribution plate (3).Distance between every dispensing branch (1) and the adjacent dispensing branch (1) is less than 10mm.
2,, it is characterized in that distributing the tapering of the work light face cone body of boring (2) to answer≤60 ℃ according to the described distributor of claim 1.
3, according to the described distributor of claim 1, the central axis that it is characterized in that every dispensing branch (1) must and distribute between the central axis of awl (2), distribution plate (3) and inlet plenum (4) angle to answer≤30 ℃.
