Embodiment 1

[0018] see Figure 1 to Figure 3 , these three accompanying drawings show the appearance structure schematic diagram of the first embodiment of the equipment for separating pulverized coal by introducing material according to the present invention. The device is composed of a material-inducing hollow part 1, a material-introducing air duct 2, and a vertical hollow part 3. The leading material hollow part 1 includes a horizontal hollow part 12 connected with the discharge opening 32 of the vertical hollow part 3, and the end 11 of the horizontal hollow part 12 near the discharge port 32 is equipped with a material introduction air duct 2, which is hollow in the horizontal direction. The part 12 is provided with a distributing port 14 for the falling of the furnace coal, and its end is a discharge port 15 for coal dust, and a spray nozzle is arranged on the transverse hollow part 12 between the material distributing port 14 and the discharge port 15. Water hole 13, this water...

Embodiment 3

[0029] see Figure 5 and Image 6 , these two accompanying drawings show the appearance structure schematic diagram of the second embodiment of the equipment for separating pulverized coal by leading material proposed by the present invention. The device includes a hollow material introduction part 1 , a casing 3 installed on the upper part of the hollow material introduction part 1 , and a cyclone 8 . The structure and performance of the leading material hollow part 1 and the housing 3, as well as the leading material air pipe 2 are basically the same as those of the first embodiment.

[0030] A cyclone 8 is installed at the output end of the hollow part 1 for leading material. The cyclone 8 includes a cylindrical shell 81, a frustum-shaped shell 82 fixed on the lower edge of the cylindrical shell, and a discharge assembly. The discharge assembly includes a hollow piece 84 communicated with the discharge opening 83 of the cone-shaped housing 82 and a feed pipe 85 insta...

Abstract

The invention relates to a device for separating pulverized coal with a leading material. The device includes a vertical hollow part with a material inlet and a material discharge port, a material-leading hollow part arranged on one side of the material-discharging port, and an end area installed in the material-leading hollow The guide air duct inserted into the part or from the side wall of the guide hollow part, and the direction of the port of the guide air duct is opposite to that of the discharge port. The equipment sucks the furnace coal and coal dust through the air duct installed near the discharge port of the vertical hollow part, and does not need a large wind force, thereby saving energy.

Description

technical field [0001] The invention relates to a device for separating pulverized coal with a feed type, in particular to a device for separating furnace coal and dust coal in coking coal with a feed type. Background technique [0002] The quality of coke mainly depends on whether the coal particles in the furnace are uniform. If the diameter of the coal particles in the furnace is between 0.5-3mm, the coke output can be increased on the one hand, and the pore structure of the coke can be changed on the other hand. Pore ​​wall strength to improve the mechanical strength and post-reaction strength of coke. When using coking coal for coking, in order to improve the quality of coke, it is a better choice to use the four major coal types of gas, fertilizer, coke, and lean coal for coking, and these four types of blended coal must be crushed before coking and loaded into the furnace. Because the content of coal dust less than 0.5mm in the raw coal before entering the pulverizer...
