Description

Technical field:

[0001] The utility model relates to a water-passing plate and a connecting structure thereof, in particular to a water-passing plate of a mold for melting a quartz crucible and a connecting structure thereof. Background technology:

[0002] Quartz crucibles are necessary equipment in the production of solar panels. Therefore, with the continuous advancement of solar cell technology, the demand for quartz crucibles has also increased. At present, quartz crucibles are mainly melted by high-temperature arc method. Among them, the water plate is an auxiliary device of the quartz crucible mold, which is installed above the quartz crucible mold. Its main function is to prevent the heat in the quartz crucible mold from being lost to the outside during the melting of the quartz crucible, and at the same time serve as a reference for the electrode position; wherein the patent number 202123091390.2 discloses a quartz crucible mold water plate height control system. Although the distance between the upper end of the quartz crucible mold and the bottom of the water plate is indirectly measured by a laser rangefinder, the error of manual measurement is reduced; the height of the water plate is automatically controlled, the adjustment time is short, and the process is simple; the workload of manual measurement is greatly reduced, and the risk of personnel being scalded by the quartz crucible mold is reduced; however, the lower surface of the above-mentioned water plate is a planar structure, and there is a large gap between the mold and the graphite electrode. The heat generated will run out of the gap, and the upper edge of the mold cannot store heat. The low conversion degree of quartz sand leads to poor edge quality of quartz crucible products; at the same time, more heat is lost, resulting in increased power consumption. Utility model content:

[0003] The utility model aims to provide a water-passing plate of a mold for melting a quartz crucible and a connecting structure thereof, which has a simple structure, reduces power consumption and ensures the quality of the upper edge of the quartz crucible product.

[0009] Furthermore, a vertically arranged groove is opened on the inner wall of the melting cavity, and a strip block matching the groove is fixed on the outer side wall of the mold, and the strip block is movably inserted in the groove.

[0010] The advantages of the utility model are as follows: 1. The utility model has a simple structure and is easy to implement.
