[0021] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described below in conjunction with the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a conveyor mechanism for smelting an ore-heat furnace, comprising a conveyor body 1, a surrounding frame 2 is arranged on the top of the conveyor body 1, two circular holes 3 are opened on one side of the outer wall of the surrounding frame 2, one side of the outer wall of the conveyor body 1 contacts with a dust collecting box 4, a cover plate 5 is placed on the top of the dust collecting box 4, two ventilation pipes 6 are fixedly penetrated on the top of the cover plate 5, and the input ends of the two ventilation pipes 6 are threadedly connected to the inside of the two circular holes 3, one side of the outer wall of the dust collecting box 4 contacts with an exhaust fan 7, one side of the outer wall of the exhaust fan 7 is fixedly installed with a connecting pipe 8, and the output end of the connecting pipe 8 is connected with the inside of the dust collecting box 4, one side of the outer wall of the dust collecting box 4 contacts with a water tank 9, a water cover 10 is placed on the top of the water tank 9, a connecting water pipe 11 is fixedly penetrated on the top of the water cover 10, and the output end of the connecting water pipe 11 is connected with the inside of the dust collecting box 4, a water pump 12 is fixedly installed on the outer wall of the connecting water pipe 11, and the bottom of the water pump 12 contacts with the top of the water cover 10.

[0024] The effect achieved by the entire embodiment 1 is that, when in use, the enclosure 2 is arranged on the conveyor body 1 and is installed in a detachable manner, and then a dust box 4 is contacted on one side of the conveyor body 1, two ventilation pipes 6 are fixedly penetrated on the cover plate 5 placed on the top of the dust box 4, and the input ends of the two ventilation pipes 6 are both threadedly connected to the two circular holes 3 opened on one side of the outer wall of the enclosure 2. At this time, the exhaust fan 7 contacted on one side of the outer wall of the dust box 4 is started, and under the action of the connecting pipe 8, the dust generated by the conveyor when conveying the raw materials reaches the inside of the dust box 4 along the two ventilation pipes 6. Since a water tank 9 is contacted on one side of the outer wall of the dust box 4, and the connecting water pipe 11 is fixedly penetrated, the dust box 4 can be transported to the inner part of the dust box 4. It is passed through a water cover 10 placed on the top of the water tank 9, thereby opening a water pump 12 placed on the water cover 10, so that the water in the water tank 9 flows into the dust box 4 along the connecting water pipe 11. Because a rotating nozzle 13 is fixedly installed at the output end of the connecting water pipe 11, the water reaches the rotating nozzle 13 along the connecting water pipe 11, and combines with the dust in the dust box 4 in the form of water mist, and then falls into the dust box 4. After a certain period of time, it is concentratedly processed to avoid the dust generated by the conveyor transporting raw materials from being emitted into the air, thereby not polluting the air, and not being absorbed by the staff to affect their physical and mental health, thereby improving the use effect of the smelting conveyor mechanism of the ore furnace.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, a rotating nozzle 13 is fixedly installed on the output end of the water pipe 11, a horizontal plate 14 is fixedly installed on one side of the outer wall of the conveyor body 1, and two electric push rods 15 are fixedly installed on the top of the horizontal plate 14. Cleaning brushes 16 are fixedly installed on the output ends of the two electric push rods 15, and the top of the cleaning brush 16 is in contact with the bottom of the conveyor body 1, and a collecting frame 17 is in contact with one side of the outer wall of the conveyor body 1.

[0026] The effect achieved by the entire embodiment 2 is that, since a cross plate 14 is installed between the two legs of the conveyor body 1, two electric push rods 15 are installed on the cross plate 14, and a cleaning brush 16 is fixedly installed between the output ends of the two electric push rods 15, when the conveyor is conveying raw materials, residual impurities will be adsorbed on its conveyor belt. At this time, the two electric push rods 15 are started to drive the cleaning brush 16 to rise to a suitable position, and the residual impurities on the conveyor belt are cleaned and then fall into the collection frame 17, which further avoids the residual impurities falling on other places and causing environmental pollution, thereby improving the use effect of the smelting conveyor mechanism of the electric arc furnace.

[0027] Working principle: First, the enclosure 2 is installed on the conveyor body 1, and the two ventilation pipes 6 are installed between the enclosure 2 and the dust box 4. When the ore-smelting conveyor is conveying raw materials, the exhaust fan 7 is turned on. Under the action of the connecting pipe 8 and the two ventilation pipes 6, the dust generated by the transportation of the raw materials enters the dust box 4 along the two ventilation pipes 6. At this time, the water pump 12 fixedly installed on the connecting water pipe 11 is turned on. Since the connecting water pipe 11 and the rotating nozzle 13 fixedly installed at the output end of the connecting water pipe 11 are both inside the dust box 4, the water in the water tank 9 reaches the rotating nozzle 13 along the connecting water pipe 11 and is discharged in the form of water mist. The impurities in the dust box 4 are combined with the dust in the dust box 4, and then fall into the dust box 4. After a certain period of time, they are processed centrally. Secondly, impurities will also remain on the conveyor belt of the conveyor. At this time, the two electric push rods 15 installed on the cross plate 14 are started to drive the cleaning brush 16 to move upward a suitable distance, and the impurities on the conveyor belt are cleaned and then fall into the collection frame 17. In general, the dust generated by the conveyor transporting materials is absorbed and processed to avoid being emitted into the air, thereby improving environmental protection, and will not be absorbed by the staff, which will affect their physical and mental health, thereby improving the use effect of the smelting conveyor mechanism of the ore-fired furnace.

[0028] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields.
