Description

Technical Field

[0001] The utility model belongs to the field of glass production equipment, in particular to a crucible for a glass frit furnace and a component thereof. Background Art

[0002] Glass production usually refers to the process of melting glass raw materials at high temperature to form a glass solution, which is then cooled by water quenching or other methods to form solid glass. The crucible in the existing frit furnace technology is as follows: Figure 5 As shown, it includes a crucible body 1 and a pull rod 5. The bottom of the crucible body 1 is provided with a leakage hole 2, and the pull rod 5 is detachably connected to the leakage hole 2. When heating the raw material, in order to prevent the raw material from falling directly from the leakage hole 2, the pull rod 5 needs to be used to block the leakage hole 2 until the raw material is completely melted to form glass liquid, and then the pull rod 5 is pulled out from the leakage hole 2, and the glass liquid enters the cooling water container below through the leakage hole 2 for collection. There are the following problems in using this crucible to heat the raw material: 1. Since the raw material needs to be completely melted first, the discharge rod is in contact with the raw material for a long time, which makes it susceptible to corrosion. Generally, the pull rod 5 needs to be replaced after heating 3 to 4 pots of raw materials. The cost of the pull rod 5 is about 90 yuan, so the consumable cost is high. 2. The raw materials in the crucible body 1 need to be completely melted before the pull rod 5 can be taken out, and the next pot of raw materials can only be heated after the glass liquid in the crucible body 1 completely flows out of the leakage hole 2, resulting in the inability to achieve continuous production. 3. During the glass liquid collection process, the heat exchange area between the inner surface of the crucible body 1 and the outside air is expanded, resulting in heat loss. 4. During the glass liquid collection process, the falling glass liquid is prone to splashing due to the accumulation and diffusion of high-temperature cooling heat. The high-temperature glass liquid and boiling water are easy to scald nearby personnel, thus posing a safety hazard. 5. The glass liquid discharged at one time is large, and the required cooling pool volume is large.

[0003] In summary, the current crucibles and their configurations in the process of producing glass in a frit furnace have problems such as intermittent production, high consumables costs, high energy consumption, serious production safety hazards, and low output and equipment utilization efficiency. Utility Model Content

[0004] The utility model aims to provide a structural innovation of a crucible device for a glass frit furnace, so as to realize continuous feeding of raw materials and continuous production of glass, reduce consumables, reduce the volume of a cooling device and improve resource utilization.

[0005] A crucible for a glass frit furnace in the present invention comprises a crucible body modification, namely, a guide groove is opened around a leakage hole at the bottom center of the crucible body, the guide groove is connected to the leakage hole, and an alumina ball plugging material is added to achieve the purpose of continuous glass production.

[0006] Working principle and beneficial effects of this solution: Through the setting of the diversion groove, before feeding the raw materials, the top of the liquid leakage hole is blocked with a spherical high-temperature resistant object, alumina balls. At this time, the liquid leakage hole is connected to the diversion groove; after the raw materials are heated and melted in the crucible body, the glass liquid enters the liquid leakage hole through the diversion groove and flows out, thereby realizing the continuous feeding of the raw materials. The continuous feeding of the raw materials reduces the heat loss in the crucible body. Since the glass liquid flows out of the liquid leakage hole continuously in small amounts, splashing during the cooling process of the glass liquid is avoided. At the same time, due to the small flow rate of the glass liquid, it can be cooled with a relatively small cooling pool.

[0007] Further, the diversion groove is 2 - 3 cm long, 2 - 3 mm wide, and 2 - 3 mm deep.

[0008] Further, there are multiple diversion grooves. Preferably 2 - 6. The setting of multiple diversion grooves helps the glass liquid flow out of the liquid leakage hole better.

[0009] Further, multiple said diversion grooves are longitudinally evenly distributed around the liquid leakage hole. This helps the glass liquid enter the liquid leakage hole more evenly from multiple directions.

[0010] The crucible assembly for a glass frit furnace further includes a baffle ball used in cooperation with the liquid leakage hole and the diversion groove. The diameter of the baffle ball is 6 - 10 cm. By blocking the liquid leakage hole with the baffle ball, it is avoided that the unmolten raw materials enter the liquid leakage hole due to excessive flow rate. Since the liquid leakage hole is connected to the diversion groove, the glass liquid can enter the liquid leakage hole normally through the diversion groove.

[0011] Further, the baffle ball is an alumina ball. Description of the Drawings
