[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 - Figure 4 , the present invention provides a technical solution: a medium-frequency furnace nozzle, including a main body mechanism 1 and a disassembly and assembly mechanism 2. The disassembly and assembly mechanism 2 is located above the main body mechanism 1. The main body mechanism 1 includes a medium-frequency furnace body 101, a fixed nozzle 102 and a nozzle ladle 103. The fixed nozzle 102 is fixedly installed at the rear end of the medium-frequency furnace body 101, and the nozzle ladle 103 is located behind the medium-frequency furnace body 101;

[0024] The main body mechanism 1 further includes a molten iron slag filter support 104, a mechanical motor 105, a reinforcing rod 106 and a scraper 107. The molten iron slag filter support 104 is movably installed inside the nozzle ladle 103. The mechanical motor 105 is located above the nozzle ladle 103. The reinforcing rod 106 is fixedly installed at the transmission end of the lower end of the mechanical motor 105, and the scraper 107 is fixedly installed at the lower end of the reinforcing rod 106. When using the medium-frequency furnace body 101 for melting operation of metals, the melted high-temperature molten iron continuously contacts the furnace wall of the medium-frequency furnace body 101, sometimes burning out the furnace lining and forming molten slag floating on the surface of the molten iron, resulting in more waste slag in the molten iron. During the treatment process of the molten iron, the staff tilts the medium-frequency furnace body 101, so that the molten iron enters the nozzle ladle 103 through the fixed nozzle 102. The molten iron slag filter support 104 filters the waste slag in the molten iron, so that the waste slag is isolated above the molten iron slag filter support 104. The mechanical motor 105 works to drive the reinforcing rod 106 to rotate, and the reinforcing rod 106 drives the scraper 107 to rotate, scraping the waste slag attached to the molten iron slag filter support 104 to ensure the filtering efficiency of the molten iron.

[0025] The disassembly and assembly mechanism 2 includes a socket support 201 and a socket groove 202. The socket support 201 is fixedly installed at the left and right ends of the molten iron slag filter support 104. The socket groove 202 is fixedly arranged at the upper end of the socket support 201. The disassembly and assembly mechanism 2 further includes a socket rod 203 and a movable buckle 204. The socket rod 203 is fixedly installed at the left and right ends of the upper end of the ladle 103 of the nozzle. The movable buckle 204 is movably installed at the outer end of the ladle 103 of the nozzle. The disassembly and assembly mechanism 2 further includes a positioning groove 205 and a support frame 206. The positioning groove 205 is fixedly arranged at the outer end of the socket support 201. The support frame 206 is fixedly installed at the right end of the ladle 103 of the nozzle. The disassembly and assembly mechanism 2 further includes a hydraulic cylinder 207 and an adjusting rod 208. The hydraulic cylinder 207 is fixedly installed at the upper end of the support frame 206. The adjusting rod 208 is fixedly installed at the transmission end of the lower end of the hydraulic cylinder 207. The mechanical motor 105 is located at the lower end of the adjusting rod 208. The disassembly and assembly mechanism 2 further includes a liquid guide hopper 209. The liquid guide hopper 209 is fixedly installed at the lower end of the ladle 103 of the nozzle. The liquid guide hopper 209 is connected to the ladle 103 of the nozzle in a through manner. The disassembly and assembly mechanism 2 further includes a buffer pipe 210. The buffer pipe 210 is fixedly installed at the lower end of the liquid guide hopper 209. The buffer pipe 210 is connected to the liquid guide hopper 209 in a through manner. The filtered molten iron enters the interior of the liquid guide hopper 209 and then flows out through the buffer pipe 210 under the action of gravity. Since the buffer pipe 210 is bent, it plays a role of buffering and guiding the discharged molten iron, reducing the splashing during the collection of molten iron. When the molten iron slag filter support 104 needs to be repaired or replaced, the staff operates the hydraulic cylinder 207 to separate the scraper 107 from the molten iron slag filter support 104 and adjust it to a suitable position. Then, by pressing the movable buckle 204, it is separated from the positioning groove 205. The staff pulls the socket support 201 to separate the socket groove 202 from the socket rod 203, and the molten iron slag filter support 104 can be taken out for repair or replacement work.

[0026] Working principle: When using the intermediate frequency furnace body 101 for melting metal, the molten high-temperature iron water constantly contacts the furnace wall of the intermediate frequency furnace body 101. Sometimes, it will burn out the furnace lining and form slag floating on the liquid surface of the iron water, resulting in more waste slag in the iron water. During the treatment process of the iron water, the staff tilts the intermediate frequency furnace body 101, so that the iron water enters the nozzle ladle 103 through the fixed nozzle 102. The iron water slag filter bracket 104 filters the waste slag in the iron water, so that the waste slag is isolated above the iron water slag filter bracket 104. The mechanical motor 105 works to drive the reinforcing rod 106 to rotate, and the reinforcing rod 106 drives the scraper 107 to rotate, scraping the waste slag attached to the iron water slag filter bracket 104 to ensure the filtering efficiency of the iron water. The filtered iron water enters the inside of the liquid guide hopper 209 and then flows out through the buffer pipe 210 under the action of gravity. Since the buffer pipe 210 is bent, it plays a role of buffering and guiding the discharged iron water, reducing the splashing during the iron water collection process. When the iron water slag filter bracket 104 needs to be repaired or replaced, the staff operates the hydraulic cylinder 207 to separate the scraper 107 from the iron water slag filter bracket 104 and adjust it to a suitable position. Then, by pressing the movable buckle 204, it is separated from the positioning groove 205. The staff pulls the socket bracket 201 to separate the socket groove 202 from the socket rod 203, and the iron water slag filter bracket 104 can be taken out for repair or replacement operations.

[0027] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement made by those of ordinary skill in the art to the technical solution of the present invention shall not depart from the essence and scope of the technical solution of the present invention.
