Description

Technical Field

[0001] The utility model relates to the technical field of smelting, in particular to a furnace which is convenient to clean. Background Art

[0002] Smelting is a pyrometallurgical process in which metal materials and other auxiliary materials are put into a heating furnace to be melted and conditioned. Inside the furnace at a high temperature (1300 - 1600K), certain physical and chemical changes occur to the furnace charge, producing crude metal or metal concentrate and slag. In addition to concentrates, roasted ores, sintered ores, etc., sometimes fluxes that make the furnace charge easier to melt and reducing agents added for a certain reaction need to be added. In addition, to provide the necessary temperature, fuel is often added for combustion, and air or oxygen-enriched air is sent in. The crude metal or metal concentrate is separated into two layers due to its very low mutual solubility with the molten slag and density difference. The concentrates include matte, yellow slag, etc., which still need to be treated by blowing or other methods to obtain the metal.

[0003] After using the smelting furnace, some residues will be generated. When pouring the slag out of the furnace, the poured slag needs to be put into a slag box and lifted away or immediately spread out for cooling after pouring. Since the smelting furnace is not convenient to tilt, it is very likely that the cleaning operation will be cumbersome and time-consuming during slag removal. If the slag is not spread out and cooled in time, it is extremely likely that a safety accident will occur, posing a danger to the staff. Therefore, how to design a furnace that is convenient to clean the molten slag after smelting is particularly important. In view of this, we propose a furnace that is convenient to clean.

[0023] The present utility model will be further described below with reference to the accompanying drawings:

[0024] As Figures 1 - 5 shown, a furnace that is convenient for cleaning includes a bracket 2. A rotating mechanism 3 for rotating the furnace 1 is provided in the middle of the bracket 2. A robotic arm 4 for supporting and adjusting the angle and direction of the cleaning movement mechanism 5 is provided above the bracket 2. The other end of the robotic arm 4 is provided with a cleaning movement mechanism 5, and a cleaning scraper mechanism 6 is provided at the end of the cleaning movement mechanism 5.

[0025] In this embodiment: The rotating mechanism 3 includes rotating sleeves 305 symmetrically fixed on the middle of the bracket 2. A rotating shaft 303 is rotatably connected to the rotating sleeves 305. A connecting block 306 is fixed at one end of the rotating shaft 303. The connecting blocks 306 are symmetrically fixed on both sides of the furnace 1. A first worm gear 304 is fixed at the other end of the rotating shaft 303. A first worm 302 is engaged with the lower side of the first worm gear 304. A first power assembly 301 is provided at the other end of the first worm gear 304. The first power assembly 301 is fixed on the bracket 2. The first power assembly 301 is a motor connected to a speed reducer. The output end of the speed reducer is fixedly connected to the first worm 302, so that the furnace can be tilted with the rotation of the rotating shaft 303, making it more convenient to pour the molten metal.

[0026] In this embodiment: The robotic arm 4 includes a boom 402 rotatably connected to the upper part of the bracket 2 and a first hydraulic rod 401. The first hydraulic rod 401 is rotatably connected to the lower side of the boom 402. A second hydraulic rod 403 is rotatably connected to the upper side of the boom 402. The other end of the second hydraulic rod 403 is rotatably connected to one end of a forearm 404. A third hydraulic rod 405 is rotatably connected to the upper side of the forearm 404, making it more convenient and safe to send the cleaning movement mechanism 5 into the furnace 1 for slag cleaning work.

[0027] In this embodiment: The cleaning movement mechanism 5 includes a frame body 502. The frame body 502 is rotatably connected to the other end of the small arm 404 and the third hydraulic rod 405. A second power assembly 503 is arranged outside the frame body 502. The second power assembly 503 has the same structure as the first power assembly 301, which will not be elaborated here. The output end of the second power assembly 503 is connected to a second worm 505. A second worm gear 504 is engaged on one side of the second worm 505. A lead screw 501 passes through the center of the second worm gear 504. The second worm gear 504 is threadedly connected to the lead screw 501. The lead screw 501 passes through the frame body 502. A cavity is arranged inside the frame body 502. Both the second worm gear 504 and the second worm 505 are placed in the internal cavity of the frame body 502. The second worm gear 504 is rotatably connected to the frame body 502. A receiving groove is opened at the bottom of the lead screw 501. The output end of the second power assembly 503 drives the second worm 505 to rotate. The rotation of the second worm 505 drives the second worm gear 504 to rotate. The rotation of the second worm gear 504 drives the lead screw 501 to move downward relative to the frame body 502, so that the cleaning scraper mechanism 6 moves up and down relative to the furnace 1.

[0028] In this embodiment: The cleaning scraper mechanism 6 includes an upper connecting piece 601 fixedly connected to the lower end of the lead screw 501. A plurality of connecting rods 603 distributed in a circumferential array are hinged on the upper connecting piece 601. The other end of the connecting rod 603 is hinged to a cleaning scraper 604. The other end of the cleaning scraper 604 is hinged to a lower connecting piece 602. The upper part of the lower connecting piece 602 is slidably connected to the receiving groove at the bottom of the lead screw 501, so that the cleaning scraper 604 will not open before reaching the bottom of the furnace 1 and will open after reaching the bottom, so that the slag inside the furnace 1 can be cleaned as much as possible.

[0029] In this embodiment: A pouring port is opened at the upper part of the furnace 1, which is convenient for pouring the molten metal and cleaning the slag.

[0030] Working principle and usage process of the utility model: After the smelting process is completed, start the output end of the first power component 301 to drive the first worm 302 to rotate. The first worm 302 drives the first worm gear 304 to rotate. The rotation of the first worm gear 304 drives the rotating shaft 303 to rotate. The rotating shaft 303 drives the furnace 1 to tilt through the fixed connecting block 306, so that the molten metal in the furnace 1 is poured out; after the process of pouring the molten metal is completed, start the first hydraulic rod 401 to move to drive the boom 402 to move, the second hydraulic rod 403 to move to drive the forearm 404 to move, and the third hydraulic rod 405 to move to drive the frame body 502 to move. Each component of the robotic arm 4 cooperates to align the cleaning scraper mechanism 6 with the furnace 1; start the output end of the second power component 503 to drive the second worm 505 to rotate. The second worm 505 drives the second worm gear 504 to rotate. The rotation of the second worm gear 504 drives the lead screw 501 to move downward relative to the frame body 502, so that the cleaning scraper mechanism 6 enters the interior of the furnace 1. When the lower connecting member 602 reaches the bottom of the furnace 1, due to the action of pressure, the lower connecting member 602 moves upward relative to the lead screw 501, so that the cleaning scraper mechanism 6 opens. The second power component 503 reverses, so that the lead screw 501 moves upward relative to the frame body 502. During this process, due to the reaction of the slag, the cleaning scraper mechanism 6 always remains open until the cleaning scraper mechanism 6 takes the slag away from the furnace 1. Under the action of gravity, the cleaning scraper mechanism 6 returns to the closed state, thus completing the cleaning of the slag.

[0031] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art of this industry should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed.
