[0023] like Figures 1 to 7As shown, it shows an environmentally friendly and energy-saving smelting furnace for metallurgy in one embodiment of the present invention, including a smelting table 1 and a flue gas pipe 4. A smelting barrel 2 is fixedly installed on the inner wall of the smelting table 1, and a fixing frame 3 is fixedly installed on the top of the smelting table 1. The surface of the smelting barrel 2 is provided with an energy-saving device for circulating the exhaust gas generated by the equipment and achieving energy saving. The energy-saving device includes a motor 1 51, which is fixedly installed on the surface of the smelting barrel 2. A turntable 1 52 is fixedly installed on the output end of the motor 1 51. A turntable 2 53 is rotatably installed on the inner wall of the smelting barrel 2. A rotating shaft 54 is fixedly passed through the surface of the turntable 2 53. A motor 2 55 is fixedly installed on the surface of the fixing frame 3. The output end of the motor 2 55 A reciprocating screw 56 is fixedly installed, a cover plate 57 is slidably installed on the surface of the fixed frame 3, an exhaust pipe 58 is fixedly penetrated through the top of the cover plate 57, a water tank 59 is fixedly penetrated through the surface of the flue gas pipe 4, a water pipe 510 is fixedly penetrated through the surface of the water tank 59, and a steam pipe 511 is fixedly penetrated through the top of the water tank 59. A closing plate 512 is slidably installed on the inner wall of the smelting vat 2, a sleeve plate 513 is sleeved on the end of the rotating shaft 54 close to the cover plate 57, a telescopic elastic rod 514 is fixedly installed on the top of the closing plate 512, and a stirring plate 515 is fixedly installed on the circumferential surface of the rotating shaft 54. The rotation of the rotating shaft 54 drives the stirring plate 515 to rotate, and the rotation of the stirring plate 515 stirs the inside of the smelting vat 2.

[0024] In some examples, turntable 2 53 is in contact with turntable 1 52, a threaded groove is provided at one end of the rotating shaft 54 close to the cover plate 57, the angle of the stirring plate 515 is set to an inclined angle, and the end of the exhaust pipe 58 away from the cover plate 57 is fixed through the surface of the flue gas chimney 4, and is transported to the flue gas chimney 4 through the exhaust pipe 58, and then the high-temperature flue gas passes through the flue gas chimney 4.

[0025] The cover plate 57 is slidably connected to the reciprocating screw 56, and the cover plate 57 and the reciprocating screw 56 are connected by threads. The closing plate 512 and the rotating shaft 54 are connected by threads. The free end of the telescopic elastic rod 514 is fixedly connected to the sleeve plate 513. The surface of the closing plate 512 is provided with a thermal insulation coating for enhancing the sealing and thermal insulation effect. The rotation of the rotating shaft 54 drives the closing plate 512 to move upward, and the closing plate 512 moves upward until the cover plate 57 and the smelting ladle 2 are sealed.

[0026] For example, Figures 1 to 7As shown, the staff puts the material into the interior of the smelting barrel 2 and starts the second motor 55. The output end of the second motor 55 rotates to drive the reciprocating screw 56 to rotate. Since the reciprocating screw 56 is connected to the cover plate 57 by a threaded connection, the reciprocating screw 56 rotates to drive the cover plate 57 to move downward until the smelting barrel 2 is sealed tightly. Then the first motor 51 is started. The rotation of the first motor 51 drives the turntable 1 52 to rotate. Since the turntable 1 52 contacts the turntable 2 53, the rotation of the turntable 2 53 drives the rotating shaft 54 to rotate. At the same time, the staff heats the smelting barrel 2. The rotation of the rotating shaft 54 drives the stirring plate 515 rotates, and the stirring plate 515 rotates to stir the inside of the smelting barrel 2, thereby improving the consistency and uniformity of the materials, ensuring the sufficiency and stability of the material reaction during the metallurgical smelting process, and helping to improve the quality of the smelting products. At the same time, because the closing plate 512 is connected to the rotating shaft 54 through a threaded connection, the rotating shaft 54 then rotates to drive the closing plate 512 to move upward, and the closing plate 512 moves upward until it seals the cover plate 57 and the smelting barrel 2, further improving the sealing and heat insulation performance of the smelting barrel 2, thereby reducing the energy consumption for maintaining the dimensions, thereby achieving the effect of environmental protection and energy saving.

[0027] When the smelting drum 2 generates high-temperature flue gas and exhaust gas during operation, it is transported to the flue gas chimney 4 through the exhaust pipe 58. Then, the high-temperature flue gas passes through the flue gas chimney 4, and the flue gas heats the water inside the water pipe 510. Then, the water inside the water tank 59 becomes high-temperature water vapor under the action of the flue gas. At this time, the water vapor is pumped into the interior of the smelting table 1 through the water vapor pipe 511. At this time, the water vapor assists in insulating the smelting drum 2 and heats the outer wall of the smelting drum 2 through the water vapor, thereby reducing the temperature difference between the inside and the outside of the smelting drum 2. This effect is to achieve auxiliary insulation by reducing the temperature difference and slowing down heat loss, and avoid the outer wall temperature from being too low and then condensing, thereby maintaining a specific temperature environment instead of directly heating the inner tank 2, further reducing the equipment's energy demand for maintaining the internal temperature of the smelting drum 2.

[0028] like Figures 1 to 7 As shown, it shows another embodiment of the present invention, the circumferential surface of the rotating shaft 54 is provided with an anti-adhesion device for driving the stirring plate 515 to vibrate to prevent the material from condensing and adhering to the surface of the stirring plate 515, the anti-adhesion device includes a rotating plate 61, the surface of the rotating plate 61 is rotatably penetrated by a rotating rod 1 62, the circumferential surface of the rotating rod 1 62 is fixedly mounted with a stirring rod 63, the inner wall of the smelting barrel 2 is fixedly mounted with a box body 64, the surface of the stirring plate 515 is fixedly mounted with a knocking plate 65, the circumferential surface of the rotating shaft 54 is fixedly mounted with a convex disc 66, the surface of the box body 64 is rotatably mounted with a rotating frame 67, the circumferential surface of the rotating frame 67 is fixedly mounted with a gear 68, the circumferential surface of the rotating frame 67 is fixedly mounted with an eccentric wheel 69, the circumferential surface of the box body 64 is slidably penetrated by a sliding plate 610, the surface of the sliding plate 610 is fixedly mounted with a knocking rod 611, and the knocking rod 611 moves to contact and collide with the surface of the knocking plate 65. In some examples, the rotating shaft 54 rotates through the surface of the box body 64, and the surface of the protruding strip disk 66 is provided with protruding strips for engaging with the gear 68. The rotation of the protruding strip disk 66 drives the gear 68 to rotate, the rotation of the gear 68 drives the rotating frame 67 to rotate, and the rotation of the rotating frame 67 drives the eccentric wheel 69 to rotate.

[0029] A collision ball is provided on one end surface of the knocking rod 611 close to the knocking plate 65 for contacting and colliding with the knocking plate 65 to generate vibration. The gear 68 is engaged with the protruding plate 66. Since the protruding plate 66 is engaged with the gear 68, the rotation of the protruding plate 66 drives the gear 68 to rotate.

[0030] The circumferential surface of the rotating rod 62 is provided with a slag processing device for refining the slag on the liquid surface of the smelting vat 2. The slag processing device includes a contact plate 71, which is fixedly mounted on the circumferential surface of the rotating rod 62. A fixing ring 72 is fixedly mounted on the circumferential surface of the rotating rod 62. A slag piece 73 is fixedly mounted on the circumferential surface of the fixing ring 72. A fixing ring 2 is fixedly mounted on the end of the rotating rod 62 away from the stirring rod 63. A blade 75 is fixedly mounted on the circumferential surface of the fixing ring 2 74. A contact plate 2 76 is rotatably penetrated on the surface of the rotating plate 61. A rotating rod 77 is fixedly mounted on the circumferential surface of the contact plate 76. The contact plate 71 rotates to contact and drive the rotating rod 77 to rotate, and the rotating rod 77 rotates to drive the contact plate 2 76 to rotate.

[0031] The contact plate 1 71 contacts the inner wall of the smelting ladle 2, the surface of the slag fragment 73 is set to be the arc surface 1, the rotating rod 77 contacts the contact plate 1 71, and the rotation of the rotating rod 77 drives the contact plate 2 76 to rotate. At this time, the rotation of the contact plate 2 76 realizes the simultaneous operation of multiple processing components for the slag.

[0032] For example, Figures 1 to 7As shown, when the rotating shaft 54 rotates under the action of the turntable 1 52, it drives the rotating plate 61 to rotate, the rotating plate 61 rotates and drives the rotating rod 1 62 to rotate, the rotating rod 1 62 rotates and drives the stirring rod 63 to rotate, and the stirring rod 63 rotates to scrape the scum floating on the surface of the smelting vat 2 toward the inner wall of the smelting vat 2, so as to prevent a large amount of scum from accumulating and affecting the work of the staff. At the same time, the connection and generation of scum will consume a lot of heat. When the rotating shaft 54 rotates under the action of the turntable 1 52, it drives the convex plate 66 to rotate. Because the convex plate 66 is engaged with the gear 68, the rotation of the convex plate 66 drives the gear 68 to rotate, and the rotation of the gear 68 drives the rotating frame 67 to rotate. The rotation of the movable frame 67 drives the eccentric wheel 69 to rotate, and the eccentric wheel 69 rotates to contact and squeeze the sliding plate 610 to move upward. At this time, the sliding plate 610 moves upward under the action of the eccentric wheel 69, driving the knocking rod 611 to move, and then the knocking rod 611 moves to contact and collide with the surface of the knocking plate 65. At this time, the knocking plate 65 vibrates under the action of the knocking rod 611 and transmits the vibration to the stirring plate 515. The vibration of the stirring plate 515 prevents the material from condensing and adhering to its surface, thereby affecting the normal operation of the stirring plate 515. The material sticking to the surface of the stirring plate 515 will increase the maintenance workload of the staff, thereby increasing the equipment downtime. When this embodiment is working: when the rotating shaft 54 rotates under the action of the rotating disk 52, it drives the rotating plate 61 to rotate, the rotating plate 61 rotates and drives the rotating rod 62 to rotate, and the rotating rod 62 rotates and drives the contact plate 71 to rotate. Because the contact plate 71 contacts the inner wall of the smelting vat 2, the contact plate 71 rotates under the action of the inner wall of the smelting vat 2. At this time, the rotation of the contact plate 71 drives the rotating rod 62 to rotate, and the rotation of the rotating rod 62 drives the fixed ring 72 to rotate. At the same time, the rotation of the fixed ring 72 drives the slag pieces 73 to rotate. At this time, the rotation of the slag pieces 73 refines the slag. At the same time, the rotation of the rotating rod 62 drives the fixed ring 74 to rotate. At this time, the rotation of the fixed ring 74 drives the slag pieces 73 to rotate. The blades 75 rotate, and the blades 75 suck the refined slag into the interior of the smelting vat 2 through the water vortex rotated by the blades 75, further avoiding the accumulation of a large amount of slag and thus affecting the work efficiency of the staff, ensuring the stability of the environment in the smelting furnace, and facilitating the smooth progress of the smelting process. At the same time, the contact plate 1 71 rotates under the action of the inner wall of the smelting vat 2. Because the contact plate 1 71 contacts the rotating rod 77, the contact plate 1 71 rotates and contacts and drives the rotating rod 77 to rotate. The rotation of the rotating rod 77 drives the contact plate 2 76 to rotate. At this time, the rotation of the contact plate 2 76 realizes the simultaneous operation of multiple slag processing components, further improving the slag processing effect and efficiency.
