Abstract
The utility model provides a swirling flow type coal dust distributor, consisting of a casing, wherein an end cap is arranged at the top of the casing; the bottom surface of the end cap is connected with a swirling flow cone; a spray-coal pipe is arranged outside the circumferential of the upper section of the casing; a curved surface is provided on the inner wall of the spray-coal pipe. The utility model changes the structure of the existent spray-coal device to make the coal dust made circumferential motion in the distributor and makes the coal dust output flow not influenced by the outlet pressure fluctuation, thereby the uneven coal dust flow phenomenon and pulsation phenomenon are eliminated to stabilize the coal dust spray quantity.
Description
Technical field
The utility model relates to the Coal powder spray device that metallurgy industry uses, and is a kind of spiral-flow type pulverized coal distributor.
Background technology
Though the pulverized coal injection device that metallurgy industry uses is through multiple improvement, it still exist the arm pulverized coal flow inhomogeneous, have pulsation phenomenon, make coal dust in distributor, produce segregation, the coal ratio of blast furnace can't be improved, thereby cause damage.
Summary of the invention
The purpose of this utility model is, a kind of spiral-flow type pulverized coal distributor is provided, it has changed the structure of existing coal powder injection device, make coal dust in distributor, make circular motion, make the output flow of coal dust not be subjected to the influence of outlet pressure fluctuation, thereby eliminate the inhomogeneous and pulsation phenomenon of pulverized coal flow, stablize coal powder blowing amount etc.
The utility model is achieved through the following technical solutions for achieving the above object: the spiral-flow type pulverized coal distributor, comprise housing, and case top is installed end cap, and the end cap bottom surface is connected with the eddy flow cone, and the housing upper periphery is installed the coal powder injection pipe, and the coal powder injection inside pipe wall is a curved surface.The tapering part of eddy flow cone is corresponding with the outlet of coal powder injection pipe, offers guiding gutter on the eddy flow cone.Mounting flange below the end cap, ring flange is connected with housing, between ring flange and the end cap sealing gasket is installed.The diameter of the entrance and exit of coal powder injection pipe is identical, and coal powder injection pipe middle part diameter is less than the entrance and exit diameter.
Advantage of the present utility model is: can make pulverized coal flow even, eliminate the segregation phenomena that coal dust occurs, the output flow of coal dust is not subjected to the influence of outlet pressure fluctuation, eliminated the pulsation phenomenon of coal dust, stablize the winding-up amount of coal dust, and improved the coal ratio of blast furnace, reduced loss etc.
Description of drawings
The specific embodiment
1 is housing among the figure, and end cap 3 is installed at housing 1 top, and end cap 3 bottom surfaces are connected with eddy flow cone 9, and housing 1 upper periphery is installed coal powder injection pipe 7, and coal powder injection pipe 7 inwalls are curved surfaces 6.The tapering part of eddy flow cone 9 is corresponding with the outlet of coal powder injection pipe 7, offers guiding gutter 11 on the eddy flow cone 9.Mounting flange 2 below the end cap 3, ring flange 2 is connected with housing 1, and sealing gasket 5 is installed between ring flange 2 and the end cap 3.The diameter of the entrance and exit of coal powder injection pipe 7 is identical, and coal powder injection pipe 7 middle part diameters are less than the entrance and exit diameter.Adopt bolt 4 to connect between end cap 3 described in the utility model and the ring flange 2, end cap 3 also can adopt bolt to be connected with eddy flow cone 9, the quantity of described coal powder injection pipe 7 can be provided with as required, the curved surface 6 of coal powder injection pipe 7 inwalls can design according to hyperbola, but, its curved surface is not limited in the hyperbola form, can adjust the curve of coal powder injection pipe curved surface as required, to reach coal dust in the constant relatively requirement of inlet pressure.When the utility model uses, coal dust enters housing 1 by the bottom of housing 1, under the effect of guiding gutter 11 on the eddy flow cone 9, coal dust is moved in a circle at housing 1 inner chamber, eliminated the coal dust segregation, the inlet that coal dust enters coal powder injection pipe 7 sprays then through the coal powder injection tube cavity, and coal dust sprays under the constant relatively condition of coal powder injection tube inlet pressure, it is even to have reached the coal powder injection flow, purposes such as pulse free phenomenon.Housing 1 described in the utility model adopts anti-wear performance chrome molybdenum steel plate making preferably, and its inwall evenly is provided with one deck antifriction alloy.8 is weld seams among the figure, the 10th, and ring flange.
