Description

Technical Field

[0001] The utility model relates to the technical field of pellet transportation, in particular to a dust removal device for pellet belt transportation. Background Art

[0002] Pelletizing is an important method for agglomerating fine ore. Pelletizing is accomplished by adding an appropriate amount of water and a binder to the fine ore to form green balls with uniform viscosity and sufficient strength. These balls are then dried, preheated, and roasted to form pellets. The finished pellets are then transported using belt conveyors. Because the pellets contain a certain amount of dust between the layers of material, the relative movement between the pellets as they move from one conveyor belt to another can cause dust to rise, polluting the workshop environment. Existing dust removal methods often involve installing a spray structure above the conveyor belt transporting the pellets, spraying water into the pellets to reduce dust during transport. However, this method leaves water on the conveyor belt surface. This excess water can cause problems such as slippage and deviation during conveyance, hindering subsequent pellet transportation. To address this issue, we propose a dust removal device for conveyor belt transport of pellets. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model provides a technical solution: a dust removal device for pellet belt transportation, comprising a spraying mechanism 1 and a wiping mechanism 2, the spraying mechanism 1 and the wiping mechanism 2 are respectively fixedly assembled in the belt conveyor 4, the spraying mechanism 1 is used for spraying the pellets transported by the belt conveyor 4, so that water is mixed with the pellets, so as to avoid the dust mixed between the inner material layers from being blown outwards when the balls move relative to each other during the subsequent transportation of the pellets, thereby playing a dust-proof effect in the transportation process of the pellets. At the same time, the wiping mechanism 2 is provided to wipe and dry the transport belt for transporting the pellets, so as to avoid moisture remaining on the surface of the transport belt, thereby causing slippage between the transport belt and the pellets, and affecting the transportation effect of the pellets.

[0020] like Figure 1 As shown in, the spray mechanism 1 includes a fixing frame 11, which is fixedly mounted on the left and right side walls of the belt conveyor 4, respectively. The positions of the fixing frames 11 on both sides correspond to each other. The surfaces of the fixing frames 11 on both sides are welded and fixed with mounting frames 12. An annular frame 13 is welded and fixed in the mounting frame 12 in a left and right symmetrical manner. The annular frame 13 is rotatably connected to a spray pipe 14. The bottom of the spray pipe 14 is evenly fixed with an atomizing nozzle 15 connected to its inner cavity. The water is atomized by the atomizing nozzle 15 and sprayed onto the pellets below. A water supply pipe 16 is fixedly mounted on the top of the mounting frame 12. The water supply pipe 16 is used to be connected to an external water source. A connecting hose 17 is fixedly mounted between the output end of the water supply pipe 16 and the input end of the spray pipe 14. Water is supplied to the spray pipe 14 through the connecting hose 17 through the water supply pipe 16.

[0021] like Figure 2 As shown in the figure, a first motor 18 is fixedly mounted on the side wall of the mounting frame 12. The output end of the first motor 18 is fixedly connected to the end of the spray pipe 14. The first motor 18 is a pulse stepping motor. The first motor 18 is electrically connected to an external power supply and an external controller. After the first motor 18 is powered on, it is controlled by the external controller to drive the spray pipe 14 to perform reciprocating tilting motion within a certain angle, thereby changing the spraying direction of the atomizing nozzle 15, making the spraying of the pellets below more uniform, and improving the dust removal effect of the pellets.

[0022] like Figure 1 and Figure 3As shown in the figure, the wiping mechanism 2 includes a rotating cylinder 21, which is rotatably connected to the belt conveyor 4. A second motor 22 is embedded in the side wall of the belt conveyor 4, and the output end of the second motor 22 is fixedly connected to the end of the rotating cylinder 21. The second motor 22 is a DC brushless motor. The second motor 22 is electrically connected to an external power supply and an external controller. The rotating cylinder 21 is driven by the second motor 22 to rotate in the inner cavity of the belt conveyor 4. A sponge layer 23 is pasted on the outer wall of the rotating cylinder 21. The sponge layer 23 is made of high-temperature resistant flame-retardant sponge. The sponge layer 23 is in contact with the lower surface of the belt in the belt conveyor 4. The rotation of the rotating cylinder 21 drives the sponge layer 23 to wipe the surface of the belt to remove residual moisture on the surface of the belt.

[0023] like Figure 3 As shown in the figure, a heating component 3 is fixedly installed in the belt conveyor 4 and plugged into the rotating drum 21. By setting the heating component 3 to heat the inside of the rotating drum 21, it is convenient for the rotating drum 21 to dry the sponge layer 23, so that the sponge layer 23 maintains a good effect of wiping the belt surface. The heating component 3 includes a tubular heater 31, which is fixedly installed on the side wall of the inner cavity of the belt conveyor 4. The tubular heater 31 is plugged into the rotating drum 21, the tubular heater 31 is electrically connected to an external power supply, and the side wall of the tubular heater 31 is passed through A heat-conducting ring 33 is fixedly connected to the heat-conducting rod 32. The heat-conducting ring 33 is in contact with the inner wall of the rotating drum 21. The rotating drum 21 rotates along the heat-conducting ring 33. The tubular heater 31 transfers heat from the heat-conducting rod 32 to the heat-conducting ring 33, which heats the rotating drum 21 through the heat-conducting ring 33, thereby facilitating the drying of the sponge layer 23. There are two heat-conducting rings 33, which are symmetrically distributed on the left and right sides of the rotating drum 21. This can not only improve the stability of the support of the rotating drum 21 but also enhance the drying effect of the sponge layer 23.

[0024] like Figure 1 and Figure 2 As shown in the figure, the side wall of the rotating cylinder 21 is evenly provided with heat dissipation holes 24, and the heat dissipation holes 24 are staggered with the sponge layer 23. The heat dissipation holes 24 are arranged to facilitate the heat dissipation of the heat-conducting ring 33 to the outside, thereby drying the surface of the belt to a certain extent, further reducing the residual moisture on the belt surface.

[0025] Working principle: Figure 1 and Figure 4As shown in the figure, the spray mechanism 1 is installed above the belt conveyor 4, and the wiping mechanism 2 is installed in the belt conveyor 4. In the process of transporting the pellets, the belt conveyor 4 puts the pellets to one side of the conveyor, and the spray mechanism 1 is set close to the placement position of the pellets. When the belt conveyor 4 drives the pellets to transport, the water in the spray mechanism 1 is atomized and sprayed on the pellets, and mixed with the dust between the pellets, thereby reducing the dust generated by the subsequent transportation of the pellets in the belt conveyor 4. At the same time, the wiping mechanism 2 wipes and dries the surface of the transport belt, which can effectively reduce the residual water on the surface of the transport belt, and avoids excessive water causing slippage that affects the transport effect of the transport belt on the pellets.
