Description

Technical Field

[0001] The utility model belongs to the field of blast furnace flue gas purification equipment, and particularly relates to a feeding and distributing device for an activated carbon bin. Background Art

[0002] In the deep treatment project of blast furnace hot stove flue gas, activated carbon is used as an adsorption medium for flue gas purification. It is continuously transported from the feeding bin to the upper bin in the adsorption tower through a Z-shaped chain conveyor, undergoes a flue gas reaction in the adsorption tower, and is then continuously conveyed to the discharging bin through a chain conveyor. Problems encountered during use: When activated carbon naturally enters the bin from the feeding port, it will accumulate in a conical shape in the bin, forming a stacking angle, which greatly reduces the effective volume of the bin. Content of the Utility Model

[0003] The purpose of the utility model is to provide a feeding and distributing device for an activated carbon bin, which solves the problem that in the prior art, when activated carbon enters the bin, it accumulates in a conical shape in the bin, reducing the effective volume of the bin.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A feeding and distributing device for an activated carbon bin includes a diversion barrel, diversion vanes, and an umbrella-shaped piece. The diversion barrel is in the shape of a hollow cylinder, a connecting column is arranged at the center of the diversion barrel, and the diversion vanes are evenly distributed in the diversion barrel with the connecting column as the center. The diversion vanes are spiral-shaped and are fixed between the connecting column and the inner wall of the diversion barrel. The bottom of the connecting column is connected to the umbrella-shaped piece by bolts.

[0006] Preferably, the cross-sectional area of the umbrella-shaped piece is less than 1 / 2 of the cross-sectional area of the activated carbon bin.

[0007] Preferably, the cross-sectional area of the umbrella-shaped piece is 1 / 3 of the cross-sectional area of the activated carbon bin.

[0008] Preferably, there are 4 diversion vanes.

[0009] Preferably, a handle is arranged on one side of the top end of the diversion barrel.

[0010] The beneficial effects obtained by the utility model are as follows:

[0011] (1) The free fall of activated carbon is adjusted to an outward spiral movement through the diversion vanes, and then the activated carbon is dispersed by the umbrella-shaped piece, so that the activated carbon is evenly distributed in the bin, avoiding the accumulation of activated carbon in a conical shape and expanding the effective volume of the bin;

[0012] (2) The use of the diversion vanes not only changes the movement trajectory of the activated carbon, but also plays a buffering role, reducing the impact force on the umbrella-shaped piece and prolonging the service life of the device;

[0013] (3) Use the handle to connect the distributor to the silo, preventing the distributor from falling off, and at the same time facilitating the removal of the distributor.

[0014] (4) The connecting column of the distributor is bolted to the umbrella-shaped piece, which is convenient for installation and later disassembly and replacement. At the same time, the uniformity range of activated carbon in the silo can be adjusted by matching different sizes of the flow guiding piece and the umbrella-shaped piece.

[0018] The technical solution of the present utility model will be further described below with reference to the drawings and embodiments.

[0019] As Figure 1-2 shown, a feeding and distributing device for an activated carbon silo includes a diversion barrel 1, a flow guiding piece 4 and an umbrella-shaped piece 5. The diversion barrel 1 is in the shape of a hollow cylinder. A connecting column 2 is arranged at the center of the diversion barrel 1. Four flow guiding pieces 4 are evenly distributed in the diversion barrel 1 with the connecting column as the center. The flow guiding piece 4 is fixed between the connecting column 2 and the inner wall of the diversion barrel 1. The flow guiding piece 4 is spiral. The bottom of the connecting column 2 is connected to the umbrella-shaped piece 5 by a bolt 3. The cross-sectional area of the umbrella-shaped piece 5 is 1 / 3 of the cross-sectional area of the activated carbon silo. A handle 6 is arranged on one side of the top end of the diversion barrel 1; the handle is used to connect the distributor to the silo to prevent the distributor from falling off; the movement track of the activated carbon is an outward spiral movement through the flow guiding piece, and then the activated carbon is dispersed by the umbrella-shaped piece, and the activated carbon is evenly distributed in the silo, avoiding the accumulation of activated carbon into a cone shape and expanding the effective volume of the silo.
