Abstract
Description
Technical Field
[0001] This utility model relates to the field of kiln technology, and in particular to a glass ball adding device for kiln during firing. Background Technology
[0002] Glass beads used in kiln firing refer to glass beads used in specific processes and playing specific roles during the kiln firing process. These glass beads have specific chemical compositions and physical properties to meet the needs of the kiln during the firing stage, thereby providing a basis for adjusting the firing process, ensuring that the kiln can reach the conditions required for normal production, and guaranteeing the quality and stability of subsequent glass production. It is very dangerous for workers to add glass beads.
[0003] The glass ball adding equipment for kilns during kiln firing is a fast, efficient, and safe device for adding glass balls to large kilns. Kilns producing glass fiber, daily-use glass, glass wool, and other types of glass products must undergo a firing process during startup. This firing process is divided into heating, high-temperature firing, adding glass balls, adding batch materials, and discharging for production. However, in existing glass ball adding equipment for kilns during firing, extremely high temperatures are generated inside, accompanied by a strong overflow of high-temperature gases. This poses a significant safety threat to on-site operators. The high-temperature gases can rapidly raise the ambient temperature, causing direct burns to the skin. The overflow of high-temperature gases can also cause uneven temperature distribution around the kiln, resulting in thermal shock to the kiln shell and surrounding equipment components, shortening the overall service life of the equipment. The easy overflow of high-temperature gases from inside the kiln threatens the safety of operators and reduces the lifespan of the equipment. Utility Model Content

The telescopic frame 203 is rotatably connected to the connecting blocks 202, allowing the equipment height to be adjusted. The spur gear shaft 205 is operated, and it meshes with the gear groove 204. When rotated, the spur gear shaft 205 moves along the direction of the gear groove 204, causing the telescopic frame 203 to extend and retract, changing the equipment height. The slider 207 at the bottom of the telescopic frame 203 is slidably connected to the slide bar 208.

The connection of each component is more secure, which meets the diverse usage needs of the equipment in the kiln setting.
[0045] Working principle: The glass ball enters the stainless steel pipe 1 through the inlet hole 7, which serves as the inlet for the glass ball and provides a feed port for subsequent operations. The water inlet pipe 5 connects to an external water source, introducing water into the connecting pipe 3. The stainless steel plate 4 inside the connecting pipe 3 acts as a separator, guide, and structural reinforcement, ensuring orderly water flow within the connecting pipe 3. The water flows out through the outlet pipe 6. This cycle is to cool the connecting pipe 3 and its connected stainless steel pipe 1, preventing overheating damage to the equipment in the high-temperature environment of the kiln. It may also clean or pre-treat the glass ball entering the equipment. Compressed air enters through the compressed air inlet hole 8. The fish-scale buckle 9 at the top of the compressed air inlet hole 8 is a structure for connecting and adjusting the water pipe, controlling the sealing and firmness of the compressed air connection. When compressed air enters the stainless steel pipe 1, it forms gas... The glass balls are propelled by the airflow and transported into the kiln along the stainless steel pipe 1, enabling the addition of glass balls. The handle 10 allows the operator to hold the device and adjust its position and angle to better complete the glass ball addition task. It also allows the operator to sense the working status of the device to some extent. When the temperature inside the kiln reaches the temperature required to add glass balls, the device is inserted into the kiln's feeding port, tilted at a certain angle to facilitate the glass balls rolling into the kiln. The device is supported by a steel frame at the bottom, with a cooling water pipe connected to the front end, a water inlet at the bottom, a water return at the top, and a compressed air pipe connected to the rear end. The purpose of connecting the cooling water pipe to the front end is to protect the front structure of the device from damage by the high temperature environment inside the kiln. The purpose of connecting the compressed air pipe to the rear end is to suppress the high temperature gas inside the kiln from escaping, ensuring the safety of the operator and maintaining a stable kiln pressure.
[0046] The fixed groove 201 is connected to the front bottom of the stainless steel pipe 1, providing a basic platform for fixing and connecting the bottom of the equipment. The connecting blocks 202 are distributed at the four corners of the bottom of the fixed groove 201, acting as a bridge connecting the fixed groove 201 and the telescopic frame 203, thus enabling the construction of the entire equipment's support structure. The telescopic frame 203 is rotatably connected to the connecting blocks 202, which creates conditions for adjusting the equipment height. When the equipment height needs to be adjusted, the spur gear shaft 205 is operated. Since the spur gear shaft 205 is meshed with the gear groove 204, rotating the spur gear shaft 205 causes its teeth to interact with the gear groove 204, causing the spur gear shaft 205 to move along the direction of the gear groove 204. This facilitates changing the support angle while increasing stability. The spur gear shaft 205 also passes through the fixed column 206, which restricts the axial movement of the spur gear shaft 205. The movement of the spur gear shaft 205 ensures stable rotation. The movement of the spur gear shaft 205 drives the telescopic frame 203 connected to it to extend and retract. When the spur gear shaft 205 moves to one side, it pushes the front telescopic frame 203 to extend and retract, thereby changing the overall height of the equipment. The sliders 207 at the bottom of the two telescopic frames 203 are slidably connected to the slide bars 208. The slide bars 208 and the support plate 209 set on the adjacent side of the inner wall together provide support and guidance for the telescopic frames 203. During the height adjustment of the equipment, the sliders 207 slide along the slide bars 208, ensuring that the extension and retraction of the telescopic frames 203 can be carried out smoothly without shaking or deviation, thus ensuring the stability of the entire equipment when adjusting the height. At the same time, the support plate 209 further enhances the support strength of the bottom of the telescopic frames 203, so that the equipment can be placed stably at different heights.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
