Description
Technical field
The utility model relates to air-flow distributor in a kind of steel smelting procedure, particularly a kind of female type air-flow distributor.
Background technology
At present, the coal injection technical development is very fast in the furnace apparatus such as smelting furnace equipment such as steel-making both at home and abroad, ironmaking and steel rolling, and one of key of this technology is the distributing uniformity of coal injection on the cupola well circumference, and each winding-up pipe accumulated powder is cleared up convenience, completeness in using.
Pulverized coal injection because can coke for replacing, characteristics such as uniformity of temperature profile in the reducing gas in the stove, cupola well, and be widely used in the iron company's (as Baosteel, Hangzhou Steel Company etc.) and the smelting iron and steel factory of each steel-making, ironmaking, steel rolling class.Bituminous coal grinds to form coal dust through coal pulverizer, enters the cupola well burning by winding-up jar, winding-up trunk line, distributor body, winding-up arm, several spray guns successively.
Now the distributor that the coal dust mist is commonly used in the smelting furnace equipment be a bottle formula, disc type and three kinds of forms of bevel-type, and they easily make blowing media and coal dust produce eddy current, resistance big, easily loaded down with trivial details, the complex structure of accumulated powder, cleaning, cost height, life-span weak point in distributor.
Summary of the invention
The purpose of this utility model is to provide a kind of female type air-flow distributor, and it is simple in structure, cost is low, the life-span is long, cleaning easily.
The technical solution of the utility model is achieved in that the female type air-flow distributor, comprise support, support is provided with the pivot flange dish, be connected with the winding-up arm on the pivot flange dish, winding-up arm upper end connects spray gun, the lower end of winding-up arm is connected with distributor body, distributor body connects the winding-up trunk line, the winding-up arm is inserted on the periphery of distributor body, distributor body is to be connected and composed by a last minute part and the following part of minuteing, under divide the part middle part to be provided with to distribute awl, distribution to bore and be connected with last minute part, distribute the conical surface of awl to be provided with 6～20 diversion grooves, distribute the diversion groove of awl and following minute part inner surface to form distribution cavity.
The winding-up arm connects by pipeline and divides gas bag, divides gas bag to connect compressed air hose.
The winding-up arm is provided with the winding-up on-off valve.
The winding-up arm is provided with the arm blow down valve with dividing the gas bag junction.
Compressed air hose is provided with the air-flow on-off valve.
Distribute awl for conical, angle is 27-50 °.
Insert 6-20 winding-up arm on the periphery of distributor body.
The distribution poppet surface band arc groove shape of distributor inner chamber of the present utility model guarantees that air-flow is smooth, balanced in assigning process.Eliminated the vortex phenomenon of distributing district's air current flow freely may not occur.Distributing the awl angular range is 27 °～50 °, reduces the pumped (conveying) medium time of staying, and material is passed through fast, and air-flow velocity is stable, and through winding-up arm can not lose during air current flow substantially, and material does not accumulate.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of distributor body;
Fig. 3 is for distributing the structure chart of awl.
The specific embodiment
Below in conjunction with accompanying drawing content of the present utility model is described in further detail:
With reference to shown in Figure 1, comprise support 6, support 6 is provided with pivot flange dish 11, be connected with winding-up arm 10 on the pivot flange dish 11, winding-up arm 10 upper ends connect spray gun 1, and the lower end of winding-up arm 10 is connected with distributor body 12, winding-up arm 10 is inserted on the periphery of distributor body 12, distributor body 12 connects winding-up trunk line 13, and winding-up arm 10 connects by pipeline and divides gas bag 7, divides gas bag 7 to connect compressed air hose 9.Winding-up arm 10 is provided with winding-up on-off valve 4, and winding-up arm 10 is provided with arm blow down valve 2 with dividing gas bag 7 junctions.Be connected with air-flow on-off valve 5 on the compressed air hose 9.
With reference to shown in Figure 2, distributor body 12 is by attachment bolt 17 last minute part 14 to be fixed together with following minute part 18, under divide part 18 middle parts to be provided with to distribute awl 15, distribute awl 15 to be connected by fastening bolt 16 with last minute part 14, distribute the diversion groove 20 of awl 15 to form distribution cavity 19 with following minute part 18 inner surfaces, the distribution awl 15 in the distributor body 12 adopts high abrasion carbonization thing material.
Shown in Fig. 3 (a, b), it is conical distributing awl 15, and the conical surface is provided with 6～20 diversion grooves 20.
