[0033] Figures 1 to 6 An embodiment of the laboratory glass melting and stirring apparatus of this application is illustrated schematically.

[0034] like Figures 1 to 6As shown, this application discloses a laboratory glass melting and stirring device, including: a frame assembly 1, a replaceable handle assembly 2, and a replaceable stirring assembly 3. The frame assembly 1 includes a frame body 11, on which a motor 12 and a reducer 13 are fixedly mounted, and the frame body 11 is covered by a housing 14. The upper end of the frame body 11 is provided with a terminal block electrically connected to the motor 12, and the lower end of the frame body 11 is provided with a stirring shaft 15 connected to the reducer 13. The handle assembly 2 includes multiple handles of different lengths, each handle being connectable to the frame assembly 1, and each handle being provided with a terminal block 21 matching the terminal block. The stirring assembly 3 includes multiple stirring rods of different shapes, each stirring rod being fixedly connected to the stirring shaft 15 and rotating with the stirring shaft 15.

[0035] Through the above structural design, the laboratory glass melting and stirring device of this application embodiment can replace the handle of different lengths and the stirring rod of different shapes according to the different laboratory melting furnace and the differences in glass liquid composition and viscosity, thereby meeting the diverse needs of melting different glass liquids in the laboratory. Therefore, it is more adaptable and can meet the needs of the laboratory's frequent glass liquid melting experiments, improve the accuracy of glass melting experiments, ensure that the glass liquid is stirred evenly and fully during the melting process, and ensure the experimental effect.

[0036] In some embodiments of this application, such as Figure 2 As shown, each grip includes a bent section 22 and a hand-held section 23. The bent section 22 is bent at 90° and connects to the upper end of the frame body 11, achieving a transition from vertical stirring to horizontal hand-held operation. The hand-held section 23 connects to the bent section 22 and is horizontally positioned. The hand-held section 23 is equipped with a uniformly sized metal or rubber grip, which increases friction to maintain hand-held stability, and the uniform specifications facilitate production and reduce costs. The length of the bent section 22 varies for different grips, thus allowing for different hand-held lengths to adapt to different furnace shapes and sizes. (Reference) Figure 4 and Figure 5 As shown, when used with the pit-type high-temperature melting furnace 4, this embodiment uses a short handle for greater grip flexibility; when used with the lifting high-temperature melting furnace 5, due to the presence of its lifting platform, this embodiment uses a long handle, extending outwards to fit the furnace body size. Therefore, this embodiment offers greater furnace compatibility and ease of use.

[0037] In some embodiments of this application, such as Figure 3 As shown, a speed adjustment knob 24 is provided on the tail end face of the handheld section 23, and a speed display dial 25 is provided on the speed adjustment knob 24. By setting the speed adjustment knob 24 and the speed display dial 25, the stirring speed can be adjusted and controlled intuitively and conveniently, enabling precise stirring control. Figure 2As shown, the terminal block 21 includes a control cable 211 and a power cable 212. The control cable 211 is electrically connected to the speed adjustment knob 24, and then connected to the motor 12 to realize the speed control of the motor. The power cable 212 extends from the handle and connects to an external power source to supply power to the motor 12 and the associated circuitry.

[0038] In some embodiments of this application, such as Figure 2 As shown, the bending section 22 is a hollow tubular structure. Both the CNC cable 211 and the power cable 212 pass through the inside of the bending section 22, achieving cable harness protection and organization. Furthermore, the end of the power cable 212 exits from the connection point between the bending section 22 and the handheld section 23, which does not interfere with the operator's handheld operation. A protective conduit 213 is installed at the exit point of the power cable 212, reliably protecting the cable harness and reducing the probability of cable sheath breakage due to bending wear, thus improving equipment safety.

[0039] In some embodiments of this application, such as Figure 1 As shown, the grip assembly 2 also includes a connector 26 for connecting the bent section 22 and the frame body 11. In some embodiments of this application, the connector 26 is, for example, an external threaded ring, which is rotatably disposed at the end of the bent section 22 and screwed into an internal threaded hole on the top of the frame to connect the grip assembly 2 to the frame. Meanwhile, a connector is provided at the end of the terminal block 21, which is plugged into the terminal block, thereby enabling rapid electrical assembly of the grip assembly 2 with the motor 12 and other circuit structures, improving disassembly and replacement efficiency.

[0040] In some embodiments of this application, a connecting buckle 16 is provided at the end of the stirring shaft 15, and the stirring shaft 15 is snapped together with each stirring rod through the connecting buckle 16. Axial connecting buckles 16 are widely available on the market, and any buckle that can realize the shaft connection function is acceptable, so this application will not elaborate on them here.

[0041] In some embodiments of this application, such as Figure 6 As shown, the stirring rod includes at least a belt stirring rod and a paddle stirring rod. In some embodiments of this application, such as... Figure 6 As shown, the belt stirring rod is a double-helix belt stirring rod 31, and the paddle stirring rod includes at least a double-blade stirring rod 32 and a three-blade stirring rod 33. By setting stirring rods of various shapes, it is possible to adapt to glass melts of different compositions and viscosities, meet the different stirring requirements of glass melts at different viscosities, and make the stirring more thorough and uniform to ensure the stirring effect.

[0042] In some embodiments of this application, each stirring rod is made of platinum, which can withstand high temperatures and also serves to protect the platinum crucible containing the glass molten sample.

[0043] In some embodiments of this application, the laboratory glass melting and stirring apparatus further includes a cooling rack, which includes legs and a cooling ring. The cooling ring engages with the housing 14 of the frame assembly 1. After use, the laboratory glass melting and stirring apparatus can be placed on the cooling rack, allowing the cooling ring to support the bottom surface of the housing 14, thus suspending and cooling the stirring rod at the lower end of the frame body, thereby preventing the hot stirring rod from burning the experimenters due to improper placement.

[0044] Combination Figures 1 to 6 The following diagram illustrates the working principle of the embodiments of this application:

[0045] When using the well-type high-temperature melting furnace 4 for melting in this embodiment of the application, a short handle can be used, such as... Figure 4 As shown, during use, a suitable stirring rod is selected according to the properties of the molten glass. The corresponding handle and stirring rod are connected to the frame body 11 via connector 26 and connecting buckle 16, forming a complete stirring device. When the glass powder melts into a liquid state in the pit-type high-temperature melting furnace 4, the furnace door is opened and the stirring device is inserted into the furnace chamber, allowing the stirring rod to be submerged in the melting crucible. The speed adjustment knob 24 is rotated to a suitable speed to allow the stirring rod to perform its stirring function. After stirring, the speed adjustment knob 24 is first adjusted to 0 before lifting the stirring rod to prevent molten glass from splashing in the furnace chamber, damaging the furnace chamber and heating elements, and causing serious consequences.

[0046] In this embodiment, when used with the lifting high-temperature melting furnace 5 for melting, a long handle can be used. During use, a suitable stirring rod is selected according to the properties of the molten glass. The corresponding handle and stirring rod are connected to the frame body 11 via the connector 26 and the connecting buckle 16 to form a complete stirring device. When the glass powder melts into a liquid state in the pit-type high-temperature melting furnace 4, the lifting platform is lowered to insert the stirring device, so that the stirring rod is submerged in the melting crucible. The speed adjustment knob 24 is rotated to a suitable speed to allow the stirring rod to perform a stirring function. After stirring is completed, the speed adjustment knob 24 is first adjusted to 0 before lifting the stirring rod to prevent the molten glass from splashing in the furnace chamber, which could damage the furnace chamber and heating elements and cause serious consequences.

[0047] In summary, the laboratory glass melting and stirring device of this application includes: a frame assembly, a replaceable handle assembly, and a replaceable stirring assembly. The frame assembly includes a frame body, on which a motor and a reducer are fixedly mounted, and the frame body is covered with a shell. A terminal block for connecting to the motor is located at the upper end of the frame body, and a stirring shaft for connecting to the reducer is located at the lower end of the frame body. The handle assembly includes multiple handles of different lengths, each of which can be connected to the frame assembly, and each handle is equipped with a terminal block that matches the terminal block. The stirring assembly includes multiple stirring rods of different shapes, each of which can be fixedly connected to the stirring shaft and rotates with the stirring shaft. This application allows for the replacement of handles of different lengths and stirring rods of different shapes according to the different laboratory melting furnaces and the differences in glass melt composition and viscosity, thereby meeting the diverse needs of melting different glass melts in the laboratory. Therefore, it is more adaptable and can meet the needs of frequent glass melting experiments in the laboratory, improving the accuracy of glass melting experiments, ensuring uniform and sufficient stirring during the glass melting process, and guaranteeing experimental results.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
