Description

Technical Field

[0001] The utility model relates to the technical field of mineral smelting production equipment, in particular to a material cleaning device for an ore-heating furnace. Background Art

[0002] Submerged arc furnace is also called arc furnace or resistance furnace. It is mainly used for reducing and smelting raw materials such as ore, carbonaceous reducing agent and solvent. The feed pipe of the submerged arc furnace is located at the top of the furnace body, and the feed is completed by the weight of the charge. Since the submerged arc furnace body is large, there are multiple feed pipes on the top of the furnace body for feeding. The traditional feeding method is to feed through a conveyor belt or a distributor. The track is arranged in a ring above the feed port, and the feed pipes are distributed on the inside of the track. The feed car moves along the track to the feed port in turn to feed the charge. During the feeding period, the charge is directly discharged from the discharge port at the bottom of the feed car.

[0003] During the unloading process, due to the large height difference between the discharge port on the inner side of the track and the distributor, and the filter screen is sealed at the mouth of the feed pipe, the charge directly hits the filter screen, causing some of the charge to splash. If the splashed charge is not handled, the charge will pile up too high, affecting the normal operation of the feed car. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a cleaning device for a charge distribution of an ore-fired furnace, which provides a movable cleaning device on the charge distribution device, and when cleaning is needed, the cleaning device is lowered to complete the cleaning work in time, thereby preventing the charge from being pushed and accumulated in the track.

DETAILED DESCRIPTION

[0020] like Figure 1 , 2 , 4, and 5 show a charging and cleaning device for an electric arc furnace. The device relies on a charging device 1 to operate. The base 2 needs to be modified and a movable groove 12 is provided on the base 2. The specific modifications are as follows: the original charging device 1 is fixed on the base 2; the base 2 moves along the track through the roller 1.1; there are more than one feeding port 13 distributed on the inner side of the track; the base 2 is provided with a movable groove 12 at the end position along the moving direction. The movable groove 12 is divided into a first installation groove 12.1 and a second installation groove 12.2.

[0021] like Figure 2 , 3 As shown, the end of the cylinder 3 is rotatably connected to the side wall of the movable groove 12; the telescopic end of the cylinder 3 is movably connected to the top of the connecting rod 4; the middle of the connecting rod 4 is rotatably connected to the movable groove 12; the bottom of the connecting rod 4 is fixed to the top of the fixed scraper 5; the two sides of the fixed scraper 5 are hinged with movable scrapers 6; it should be noted that the movable scraper 6 can only rotate toward the inner side of the base 2, and when rotating inward, the movable scraper 6 is retracted to a certain angle to avoid obstruction when the device is off the track; as shown in the design in the figure, the movable scraper 6 cannot be turned outward and is blocked by the back of the rotating connection. The connecting shaft of the movable scraper 6 is connected to the driving end of the driving motor 7, and the driving motor 7 drives the movable scraper 6 to rotate inward and retract. Further, the cylinder 3 and the linkage frame 10 are located in the first mounting groove 12.1; a second mounting groove 12.2 is also provided between the first mounting groove 12.1; the outer cylinder 4.1 is located in the second mounting groove 12.2 and is rotatably connected to the side wall of the second mounting groove 12.2.

[0022] like Figure 2 , 4 As shown, the connecting rod 4 includes an outer cylinder 4.1 and a movable inner rod 4.2; the movable inner rod 4.2 is movably nested inside the outer cylinder 4.1; the side wall of the outer cylinder 4.1 is provided with a travel groove 8; the movable inner rod 4.2 is provided with a protrusion 9 corresponding to the position of the travel groove 8; the bottom of the movable inner rod 4.2 is fixedly connected to the fixed scraper 5. The bottom of the outer cylinder 4.1 is fixed to the bottom of the linkage frame 10; the linkage frame 10 is a U-shaped frame structure. The two ends of the linkage frame 10 are rotatably connected to the movable groove 12, so that the linkage frame 10 and the outer cylinder 4.1 rotate synchronously; the rod body of the movable inner rod 4.2 located below the linkage frame 10 is provided with a buffer spring 11, which can have a certain amount of up and down deformation during the scraping process to avoid deformation of the scraper when the hard friction is too large. If the fixing method is not separately introduced in the above, it is welded or threaded fastened using the common technical means of technical personnel in the industry.

[0023] Here’s how it works:

[0024] The equipment is controlled by the cylinder 3 to rotate a certain angle. After the cylinder 3 is extended, the fixed scraper 5 and the connected movable scraper 6 enter the track, and then the movable scraper 6 is controlled to be unfolded by the driving motor 7. The angle between the movable scraper 6 and the fixed scraper 5 is less than 180°, forming a guiding surface concentrated to the middle. As the distributor 1 moves, the cleaning device cleans, and the furnace charge on the inner side of the track enters the feed port 13; after the cleaning is completed, the driving motor 7 controls the movable scraper 6 to be retracted inward, the cylinder 3 retracts, and the device turns outward and leaves the inner side of the track.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
