It should be noted that the embodiments of the present application and the features therein can be combined with each other unless there is a conflict.

[0029] 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 disclosed in the following specification.

[0030] Example 1: Figure 1-Figure 5 As shown, the utility model provides a smelting furnace charging device, including a mixing mechanism 2, and a charging mechanism 1 is fixedly installed on the top of the mixing mechanism 2;

[0031] The feeding mechanism 1 includes a support 101, a solvent box 102 is fixedly installed on the top of the support 101, a cover 103 is fixedly installed on the top of the solvent box 102, two heaters 104 are fixedly installed on the bottom of the inner wall of the solvent box 102, a temperature sensor 105 is fixedly installed on one side of the inner wall of the solvent box 102, a drive motor 106 is fixedly installed on the top of the cover 103, a stirring rod 107 is fixedly installed on the bottom of the drive motor 106, a plurality of stirring blades 108 are fixedly installed on the outer wall of the stirring rod 107, a feeding pipe 109 is fixedly passed through one side of the outer wall of the solvent box 102, and a quantitative valve 110 is fixedly installed on the outer wall of the feeding pipe 109.

[0032] The effect achieved by the entire embodiment 1 is that when it is necessary to add a solvent to the smelting furnace body 204 to optimize the smelting effect and improve the metal quality, since the controller 208 is wirelessly connected to the two heaters 104, the temperature sensor 105, the drive motor 106 and the quantitative valve 110, the temperature sensor 105 is used to monitor the temperature of the solvent in the solvent box 102. When the temperature is lower than the required temperature, the controller 208 starts the two heaters 104 installed at the bottom of the inner wall of the solvent box 102 to heat the solvent until the required temperature range is reached, thereby ensuring that the solvent can be fully dissolved in the molten metal in the smelting furnace body 204 and improving the solvent and metal dissolution. The stability of the metal liquid reaction is checked, and then the driving motor 106 installed on the cover plate 103 is started by the controller 208, so that it drives the stirring rod 107 and the multiple stirring blades 108 to stir the auxiliary solvent in the solvent box 102 to make it evenly mixed. Secondly, according to the amount of molten metal in the smelting furnace body 204, the quantitative valve 110 installed on the feeding pipe 109 is started by the controller 208. Since the output end of the feeding pipe 109 is connected to the interior of the smelting furnace body 204, the auxiliary solvent with suitable temperature and even mixing in the solvent box 102 enters the smelting furnace body 204 along the feeding pipe 109 and is fully mixed with the molten metal inside, thereby improving the efficiency of the full dissolution of the auxiliary solvent and the molten metal.

[0033] Example 2: Figure 2-Figure 5 As shown, the mixing mechanism 2 includes a base 201, a circular groove 202 is formed on the top of the base 201, and four arc-shaped sliders 203 are movably embedded in the inner surface wall of the circular groove 202. A smelting furnace body 204 is fixedly installed between the tops of the four arc-shaped sliders 203. A first gear 205 is fixedly sleeved on the outer surface wall of the smelting furnace body 204. A furnace cover 206 is fixedly installed on the top of the smelting furnace body 204. A feed hopper 207 is fixedly installed on the top of the furnace cover 206. A controller 208 is fixedly installed on the top of the base 201. A forward and reverse motor 209 is fixedly installed on the top of the base 201. A driving rod 210 is fixedly installed on the top of the forward and reverse motor 209, and a second gear 211 is fixedly installed on the top of the driving rod 210, and the outer wall of the second gear 211 is meshed with one side of the outer wall of the first gear 205. An L-shaped plate 212 is fixedly installed on the top of the base 201, and the outer wall of the driving rod 210 is movably inserted into the inside of the L-shaped plate 212. A fixing plate 213 is fixedly installed on one side of the outer wall of the smelting furnace body 204, and the top of the fixing plate 213 is fixedly connected to the bottom of the support 101. The output end of the feeding pipe 109 is connected to the interior of the smelting furnace body 204.

[0034] The effect achieved by the entire embodiment 2 is that when the co-solvent with suitable temperature and uniform mixing enters the smelting furnace body 204 quantitatively along the feeding pipe 109, the controller 208 installed on the base 201 is electrically connected to the forward and reverse motor 209, so that the forward and reverse motor 209 installed on the base 201 is started by the controller 208, so that the driving rod 210 is driven to rotate inside the L-shaped plate 212 fixedly installed on the top of the base 201, thereby driving the second gear 211 to rotate on the driving rod 210. Since a circular groove 202 is provided on the top of the base 201, the four arc-shaped sliders 203 installed at the bottom of the smelting furnace body 204 are all activated. The first gear 205 is movably embedded in the circular groove 202, and the outer wall of the smelting furnace body 204 is fixedly sleeved and meshed with the outer wall of the second gear 211, so that the driving rod 210 and the second gear 211 are driven to rotate by the forward and reverse motor 209, which can drive the first gear 205 and the smelting furnace body 204 to rotate stably, and can rotate back and forth stably, thereby increasing the contact area between the flux and the metal liquid in the smelting furnace body 204, improving the uniformity of mixing between the flux and the metal liquid, thereby more effectively exerting the role of the flux itself, and accelerating the chemical reaction between the flux and the metal liquid, thereby improving the use effect of the smelting furnace.

[0035] Working principle: First, solid metal is added to the interior of the smelting furnace body 204 through the feed hopper 207, and heated to its melting temperature through the through-holes on the base 201, so that the solid metal inside is converted into liquid metal. Then, when it is necessary to add a solvent to the smelting furnace body 204 to optimize the smelting effect and improve the metal quality, the temperature sensor 105 installed on one side of the inner wall of the solvent box 102 is used to monitor the temperature of the solvent in the solvent box 102 at all times. When the temperature of the solvent inside is lower than the required temperature, the temperature sensor 105 transmits the information to the controller 208, and the controller 208 is used to The two heaters 104 installed at the bottom of the inner wall of the solvent box 102 are started to heat the solvent until it reaches the required temperature, and then the two heaters 104 are turned off by the controller 208. At the same time, the driving motor 106 installed on the cover plate 103 is started by the controller 208 to drive the stirring rod 107 and multiple stirring blades 108 to stir the solvent in the solvent box 102 to mix it evenly and improve the efficiency of dissolving with the metal liquid. Then, according to the amount of metal liquid in the smelting furnace body 204, the quantitative valve 110 is started by the controller 208 to make the solvent in the solvent box 102 evenly mixed and at a suitable temperature. The feeding pipe 109 enters the interior of the smelting furnace body 204 and makes it fully mixed and dissolved with the molten metal in the smelting furnace body 204. Then, the forward and reverse motor 209 is started by the controller 208. Since an L-shaped plate 212 is installed on the base 201, the forward and reverse motor 209 drives the driving rod 210 to rotate inside the L-shaped plate 212, so that the second gear 211 rotates stably on the driving rod 210. Secondly, the four arc-shaped sliders 203 installed at the bottom of the smelting furnace body 204 are all movably embedded in the circular groove 202 opened at the top of the base 201. Then, a first gear 205 is fixedly sleeved on the outer wall of the smelting furnace body 204. , and the first gear 205 and the second gear 211 are meshed and connected, so that the rotation of the driving rod 210 and the second gear 211 can drive the first gear 205 and the smelting furnace body 204 to rotate stably on the base 201, and make the flux in the smelting furnace body 204 fully contact with the molten metal, effectively improving the uniformity of mixing between the flux and the molten metal. In general, through the action of the feeding mechanism 1 and the mixing mechanism 2, the flux can be quantitatively dissolved in the molten metal while maintaining an appropriate temperature, and the chemical reaction between the flux and the molten metal is accelerated, thereby improving the use effect of the smelting furnace feeding device.
