This method has low heating efficiency, uneven heating of the crucible lining, and consumes electricity. It also seriously affects the smelting rhythm and reduces production efficiency.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Embodiment 1:

[0022] like Figure 1 and Figure 2 As shown, the utility model provides a crucible lining drying and heating device, comprising: a fixed plate 1; a fixed ring 2, the fixed ring 2 is located below the fixed plate 1, and the fixed ring 2 and the fixed plate 1 are connected by a connecting rod 7; a drying component, the drying component is located between the fixed plate 1 and the fixed ring 2, and the drying component is rotatably connected to the fixed plate 1 under the drive of a driving member.

[0023] The diameters of the fixing plate 1 and the fixing ring 2 are smaller than the inner diameter of the crucible, so that the entire device can be placed inside the crucible. When the crucible lining needs to be dried and heated, the device is placed inside the crucible, and the driving member drives the drying assembly to rotate to heat and dry the crucible lining.

[0024] The drying component includes a heating rod 3 and fan blades 4. The heating rod 3 is a U-shaped structure. The heating rod 3 is a metal heating rod 3. A connecting wire is arranged inside the top of the heating rod 3. When the power is turned on, the heating rod 3 dissipates heat. The heating rod 3 is connected to the driving member and rotates under the drive of the driving member. A plurality of fan blades 4 are arranged, and four are preferably arranged in the present embodiment. The four fan blades 4 are distributed in the space inside the two side walls of the heating rod 3. The four fan blades 4 are evenly connected to the driving member and rotate synchronously with the heating rod 3 under the drive of the driving member.

[0025] The driving member includes a first rotating shaft 5, a second rotating shaft 6 and a motor. The second rotating shaft 6 is connected to the output end of the motor. The motor is arranged on an insulating plate 10 (not shown in the figure). The diameter of the first rotating shaft 5 is larger than that of the second rotating shaft 6. The first rotating shaft 5 is sleeved on the second rotating shaft 6 and rotates with the second rotating shaft 6. The two ends of the heating rod 3 are respectively fixed on both sides of the first rotating shaft 5, and the four fan blades 4 are evenly distributed on the second rotating shaft 6. When the motor is started, the first rotating shaft 5 and the second rotating shaft 6 rotate, so that the heating rod 3 and the fan blades 4 rotate. The heating rod 3 is powered on to dissipate heat. During the rotation, the heat is evenly dissipated to the crucible lining, which has the effect of heating and drying the crucible lining. The fan blades 4 rotate to fan the heat flow, so that the heat flow generated by the heating rod 3 is more evenly and quickly dissipated to the crucible lining, thereby accelerating the drying efficiency and improving the drying effect.

[0026] A heat insulation plate 9 and an insulating plate 10 are arranged in sequence above the fixing plate 1. The heat insulation plate 9 isolates heat to facilitate taking out the device after drying, and the insulating plate 10 isolates power to facilitate taking out the device.

[0027] One end of the connecting rod 7 extends upward and passes through the fixed plate 1, the heat insulation plate 9 and the insulating plate 10 in sequence, and is fixed by a nut, and the other end extends downward and passes through the fixed ring 2. The connecting rod 7 serves to connect the fixed plates 1 and the fixed plates 1, and can further fix the heat insulation plate 9 and the insulating plate 10 on the fixed plate 1; a base 8 is provided at the bottom of the connecting rod 7, which serves as a support when the device is placed in the crucible, and a thread is provided at the connection between the connecting rod 7 and the fixed plate 1 and the fixed ring 2, and the connecting rod 7 is fixedly connected to the fixed plate 1 and the fixed ring 2 by threads.

[0028] In this embodiment, the second rotating shaft 6 and the first rotating shaft 5 rotate synchronously, driving the heating rod 3 and the fan blades 4 to rotate synchronously. The heating rod 3 emits heat during the rotation process and evenly disperses it to the crucible lining to heat the crucible lining. During this process, the fan blades 4 rotate to fan the heat flow to form a uniform and stable heat flow, so that the crucible lining is heated more evenly and the drying speed is faster, thereby improving the drying efficiency.

[0029] Embodiment 2:

[0030] like Figure 3 As shown, the difference between this embodiment and the first embodiment is that: the diameter of the fixed plate 1 is larger than the outer diameter of the crucible, the diameters of the heat insulation plate 9 and the insulating plate 10 are the same as the diameter of the fixed plate 1, and the heat insulation plate 9 and the insulating plate 10 are fixed in sequence on the top of the fixed plate 1 by bolts. When the lining of the crucible needs to be heated and dried, the fixed plate 1 is placed on the top of the crucible so that the drying assembly is located in the crucible and rotated to heat and dry the inside of the crucible.

[0031] In this embodiment, the fixed plate 1 is directly mounted on the top of the crucible, the heating rod 3 and the fan blades 4 are located inside the crucible, the motor is started, the first rotating shaft 5 and the second rotating shaft 6 rotate, the heating rod 3 and the fan blades 4 rotate synchronously, the heating rod 3 dissipates heat, and the fan blades 4 fan the heat flow, so as to fully heat and dry the lining of the crucible.

[0033] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
