Abstract
The utility model relates to a four-way joint of pulverized coal pipes of an iron-smelting blast furnace. According to the utility mode, a first way pipe is sealed and communicated with a fourth way pipe through a left oblique pipe; a second way pipe is sealed and communicated with a third way pipe through a right oblique pipe; the left oblique pipe is sealed and communicated with the right oblique pipe. The four-way joint has simple structure, and convenient mounting, and can guarantee the continuity and the stability of the jetting of pulverized coals of the iron-smelting blast furnace.
Description
Technical field
The utility model relates to a kind of four-way, particularly the four-way used of iron-smelting blast furnace coal pipe.
Background technology
Under the low situation of present steel industry, iron-smelting blast furnace coal injection technology is the effective measure of saving energy and reduce the cost, and is widely used.Continuity, the stability of pulverized coal injection in blast furnace are extremely important, but due to all factor blast furnaces, the coal injection system accident is stopped coal and is often occurred, and blast furnace stops suddenly coal the impact of very severe on blast-furnace smelting, can cause that speed of material descent is fast, furnace temperature is descending, even cause blowing out to freeze the accidents such as cylinder.
Summary of the invention
The iron-smelting blast furnace coal dust is carried common the using and the reserved, when accident is promptly switched, four-way is taken over easily and is stopped up, in order to overcome the shortcoming of prior art, the utility model provides a kind of iron-smelting blast furnace coal pipe four-way, it is simple in structure, and is easy for installation, can guarantee continuity, the stability of iron-smelting blast furnace breeze blowing.
The technical scheme in the invention for solving the technical problem is: a siphunculus communicates with the four-way pipe sealing by left inclined tube, and bipass communicates with the Y-tube sealing by right inclined tube, and described left inclined tube communicates with right inclined tube sealing.
The utility model is simple in structure, and is easy for installation, can guarantee continuity, the stability of iron-smelting blast furnace breeze blowing.Carrying due to coal dust is Dual-Phrase Distribution of Gas olid, therefore at transport pipe bifurcated and merging place, easily stops up, and this patent overcomes the blockage problem that coal dust flows.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model left view.
Embodiment
As shown in Figure 1, 2, a siphunculus 1 communicates with four-way pipe 10 sealings by left inclined tube 5, and bipass 2 communicates with Y-tube 8 sealings by right inclined tube 4, and sealing communicates described left inclined tube 5 at middle part with right inclined tube 6.
On the interface of a described siphunculus 1, bipass 2, Y-tube 8 and four-way pipe 10, gas thread (not shown in FIG.) is arranged.
Described left inclined tube 5 and a siphunculus 1 and four-way pipe 10 joints are fixed with respectively the first valve 3 and the 4th valve 9; Described right inclined tube 5 is fixed with respectively the second valve 4 and the 3rd valve 7 with bipass 2 and Y-tube 8 joints.
