[0001] This utility model relates to an automatic alarm device, specifically an automatic alarm device for a stirrer stopping, belonging to the field of glass production and processing technology. Background Technology

[0002] Glass, as an important inorganic non-metallic material, is widely used in construction, automobiles, electronics, optics, and chemical industries. In the glass production process, the uniformity of the molten glass directly affects the quality of the final product, such as the refractive index consistency of optical glass, the electrical properties of electronic glass, and the surface flatness of float glass. Therefore, efficient and uniform stirring of the molten glass is a crucial step in the glass melting process.

[0003] Chinese Patent Publication No. CN222159976U discloses a glass solution stirring device, including a melting furnace. The melting furnace is provided with a feed inlet, a discharge pipe, a rotating shaft, stirring blades, and a drive structure that drives the rotating shaft and stirring blades to rotate and move up and down. When the eccentric wheel is driven to rotate continuously by the drive shaft, it will drive the eccentric frame to move up and down. The eccentric frame drives the threaded shaft to move up and down through a lifting plate, which cooperates with the guide roller with internal threads.

[0004] However, the inventor of the above-mentioned device believes that there are certain defects. Because the above-mentioned device lacks a real-time monitoring and alarm mechanism for the agitator, the operator cannot detect the agitator shutdown or other abnormalities in time. If the shutdown is not dealt with in time, the motor may burn out due to prolonged stalling, and related components may also be damaged due to continuous high temperature and abnormal stress. Therefore, this utility model provides an automatic alarm device for agitator shutdown. Utility Model Content

The connecting rod is fixedly connected to an upper bevel gear and a lower bevel gear on the outer surface inside the drive box. The half-tooth bevel gear meshes with the lower bevel gear. When the half-tooth bevel gear meshes with the lower bevel gear, it drives the connecting rod to rotate in the forward direction. When the half-tooth bevel gear rotates to mesh with the upper bevel gear, it drives the connecting rod to rotate in the reverse direction.

[0008] Preferably, the upper bevel gear and the lower bevel gear are symmetrically arranged about the half-tooth bevel gear, and a second motor for driving the half-tooth bevel gear to rotate is fixedly connected to the fixed arm. The half-tooth bevel gear is driven to rotate by starting the second motor.

[0009] Preferably, the support assembly further includes a lifting mechanism for controlling the raising and lowering of the fixed arm. The lifting mechanism includes a fixed base, a fixed slide rail fixedly connected to the top of the fixed base, and a connecting slider fixedly connected to one end of the fixed arm.

Detailed Implementation

[0016] This utility model provides an automatic alarm device for a mixer to stop. Example

[0017] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A glass melt agitator includes an agitator 1 and a support assembly for supporting the agitation. The support assembly includes a fixed arm 2, one end of which is rotatably connected to a connecting rod 4. One end of the agitator 1 is detachably connected to the bottom of the connecting rod 4 via a flange. By removing the bolts between the two flanges, the agitator 1 can be easily removed as a whole for maintenance and cleaning. Both the agitator 1 and the connecting rod 4 are made of platinum-rhodium alloy, which is one of the most commonly used materials for agitating molten glass and is widely used in various glass furnaces, such as the production process of high-quality glass like optical glass, electronic glass, and borosilicate glass.

[0018] Please refer to it again. Figure 1 , Figure 2 and Figure 3 One end of the fixed arm 2 is fixedly connected to the drive box 3, and the connecting rod 4 is rotatably connected inside the drive box 3. One side of the drive box 3 is open, and a side cover 31 is detachably connected to one side of the drive box 3 by bolts. By removing the bolts on the side cover 31, the opening of the drive box 3 can be opened, making it convenient to maintain and repair the components inside the drive box 3. The drive box 3 is equipped with a monitoring mechanism for monitoring the rotation of the connecting rod 4. The monitoring mechanism includes a proximity switch 8 fixedly connected to the side cover 31. The sensing end of the proximity switch 8 points to the connecting rod 4. A circular array of metal protrusions 43 is fixedly connected to the outer surface of the connecting rod 4. When the stirrer 1 rotates, each time the metal protrusions 43 pass through the sensing area of ​​the proximity switch 8, the proximity switch will be triggered to output a pulse signal. The proximity switch 8 transmits the electrical signal to an external control device to monitor the rotation of the stirrer 1 in real time, and can be used for alarm, interlock control or record saving. Example

[0019] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The drive box 3 is equipped with a drive mechanism that drives the connecting rod 4 to rotate alternately in both directions. The drive mechanism includes a half-tooth bevel gear 32 that rotates on the inner side wall of the drive box 3. The connecting rod 4 is fixedly connected to an upper bevel gear 33 and a lower bevel gear 34 on the outer surface inside the drive box 3. The upper bevel gear 33 and the lower bevel gear 34 are symmetrically arranged about the half-tooth bevel gear 32, and the half-tooth bevel gear 32 meshes with the lower bevel gear 34.

[0020] Please refer to it again. Figure 1 , Figure 2 and Figure 3 A second motor 35 is fixedly connected to the fixed arm 2 to drive the half-tooth bevel gear 32 to rotate. The teeth of the half-tooth bevel gear 32 only occupy a part of the circumference of the bevel gear, and the rest is a smooth surface without teeth. The half-tooth bevel gear 32 is driven to rotate by starting the second motor 35. When the half-tooth bevel gear 32 meshes with the lower bevel gear 34, it drives the connecting rod 4 to rotate in the forward direction. When the half-tooth bevel gear 32 rotates to mesh with the upper bevel gear 33, it drives the connecting rod 4 to rotate in the reverse direction. During the continuous rotation of the half-tooth bevel gear 32, the connecting rod 4 is driven to rotate alternately in the forward and reverse directions. Example

[0021] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4The support assembly also includes a lifting mechanism for controlling the lifting and lowering of the fixed arm 2. The lifting mechanism includes a fixed base 21, a fixed slide rail 22 is fixedly connected to the top of the fixed base 21, and a connecting slider 25 is fixedly connected to one end of the fixed arm 2. The connecting slider 25 is slidably connected inside the fixed slide rail 22. The height of the stirrer 1 is adjusted by driving the connecting slider 25 to slide up and down inside the fixed slide rail 22.

[0022] Please refer to it again. Figure 1 and Figure 2 The fixed slide rail 22 is internally connected to a lifting screw 23, and the connecting slider 25 is internally embedded with a threaded sleeve, which is threaded to the outer surface of the lifting screw 23. The top of the fixed base 21 is fixedly connected to a first motor 24 that drives the lifting screw 23 to rotate. An alarm light 9 is fixedly connected to one side of the fixed slide rail 22. A bevel gear assembly is provided between the output shaft end of the first motor 24 and the lifting screw 23. By starting the first motor 24, the lifting screw 23 is driven to rotate. Under the action of the threaded sleeve, the connecting slider 25 is driven to slide up and down inside the fixed arm 2. If an abnormal situation occurs during the stirring process, the control equipment will control the alarm light 9 to light up and sound to warn the on-site personnel.

[0023] Working principle: The stirrer 1 is placed in the glass melting furnace. The second motor 35 is started to drive the half-tooth bevel gear 32 to rotate. When the half-tooth bevel gear 32 meshes with the lower bevel gear 34, it drives the connecting rod 4 to rotate in the forward direction. When the half-tooth bevel gear 32 rotates to mesh with the upper bevel gear 33, it drives the connecting rod 4 to rotate in the reverse direction. During the continuous rotation of the half-tooth bevel gear 32, the connecting rod 4 is driven to rotate alternately in the forward and reverse directions. The stirrer 1 causes the bubbles in the molten glass to disperse, promoting the diffusion and mixing of glass liquid in different areas. During the rotation of the connecting rod 4, each time the metal protrusion 43 passes through the sensing area of ​​the proximity switch 8, it triggers the proximity switch to output a pulse signal. The proximity switch 8 transmits the electrical signal to the external control equipment to monitor the rotation of the stirrer 1 in real time. It can also be used for alarm, interlock control, or record storage. When the stirrer 1 stops or its rotation is abnormal, the control equipment controls the alarm light 9 to light up and sound to alert the on-site personnel.
