Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4The utility model provides a technical solution: a silicon mud smelting device, including a base 1, a heat insulation sleeve 2, a heater 3, a heat conducting cylinder 4, a solenoid valve 5, a transfer bin 6, a bin cover 7, a stirring rod 8, a motor 9, a scraper 10, a gear 11, a rack 12, an electric telescopic rod 13, a fixing plate 14, a controller 15, a connecting sleeve 16, an exhaust fan 17, a hollow plate 18 and an activated carbon purification plate 19. When the silicon mud smelting device is used, Figure 1 , Figure 2 and Figure 4 First, the device can be placed at the place where the silicon mud is to be smelted, and then the screws can be inserted into the outer end of the base 1 to install and fix the device. Then, the controller 15 embedded and installed on the inner side of the right rear end of the base 1 can be used to control the electromagnetic valve 5 fixedly installed on the inner side of the upper end of the thermal insulation sleeve 2 to operate, so that the thermal insulation sleeve 2 is connected to the transfer bin 6 fixedly connected thereto through the electromagnetic valve 5. Then, the bin cover 7 connected to the outer side of the upper end of the transfer bin 6 by damping can be rotated to put the silicon mud and auxiliary materials to be smelted into the transfer bin 6, and then, under the action of gravity, they fall into the heat-conducting cylinder 4 fixedly connected to the thermal insulation sleeve 2. After the smelting material is put in, the electromagnetic valve 5 can be controlled by the controller 15 again to disconnect the connection between the thermal insulation sleeve 2 and the transfer bin 6. Then, the heater 3 installed on the inner side of the lower end of the thermal insulation sleeve 2 can be controlled by the controller 15 to operate, so that the heater 3 heats the heat-conducting cylinder 4 fitted thereon to melt the smelting material in the heat-conducting cylinder 4.

[0027] like Figure 1 , Figure 2 and Figure 4 During the smelting process of the smelting material, the controller 15 can be used to control the motor 9 fixedly installed on the thermal insulation sleeve 2 by the clamp and screws to operate, so that the motor 9 drives the stirring rod 8 connected to the bottom thereof by the coupling to rotate under the clamping limit of the thermal insulation sleeve 2. Since the stirring rod 8 is located on the inner side of the heat-conducting cylinder 4, and the outer side of the stirring rod 8 is fixedly connected with a scraper 10 that is arranged in contact with the thermal insulation sleeve 2 and the heat-conducting cylinder 4, the operation of the motor 9 facilitates the stirring rod 8 to rotate and stir the smelting material, so that the stirring rod 8 drives the scraper 10 to rotate and scrapes the smelting material in the thermal insulation sleeve 2 and the heat-conducting cylinder 4, and can feed the material into the transfer bin 6 connected to the bin cover 7, and then control the solenoid valve 5 to operate to feed the material into the heat-conducting cylinder 4, and facilitate the shielding of the bin cover 7 to reduce the contact between the smelting material and the air, so as to facilitate the smelting effect.

[0028] like Figure 1 , Figure 3 and Figure 4After the smelting is completed, the bin cover 7 can be rotated to disconnect the closed connection between it and the transfer bin 6, and then the solenoid valve 5 and the electric telescopic rod 13 fixedly installed in the fixed plate 14 can be controlled by the controller 15 to operate, so that the transfer bin 6 is connected with the thermal insulation sleeve 2, so that the electric telescopic rod 13 drives the rack 12 fixed thereon to rise and fall under the fitting limit of the fixed plate 14. Since the rear side of the upper end of the rack 12 is meshed and connected with the gear 11 fixed to the thermal insulation sleeve 2, the thermal insulation sleeve 2 is rotatably connected to the inner side of the upper end of the base 1. Therefore, through the operation of the electric telescopic rod 13, it is convenient to make the rack 12 drive the gear 11 to rotate under the fitting limit of the fixed plate 14, so that the gear 11 drives the thermal insulation sleeve 2 to rotate backward under the limit of the base 1, so as to achieve the purpose of turning and discharging the smelting material in the device;

[0029] like Figure 1 , Figure 2 and Figure 4 , and in the process of discharging the smelting material, the exhaust fan 17 fixedly installed in the connecting sleeve 16 can be controlled by the controller 15 to operate. Since the connecting sleeve 16 is symmetrically fixed to the upper sides of the left and right ends of the thermal insulation sleeve 2, the rear side of the exhaust fan 17 is provided with a hollow plate 18 fixed with screws to the connecting sleeve 16, and the front side of the exhaust fan 17 is provided with an activated carbon purification plate 19 nested and fitted with the connecting sleeve 16. Therefore, through the operation of the exhaust fan 17, the gas emitted by the smelting is conveniently sucked into the connecting sleeve 16, so that it is purified by the activated carbon purification plate 19 and then discharged, thereby facilitating the reduction of the impact on the operators and the environment.
