Abstract

The invention discloses a heating plate for the spray coating of a solar crucible, which comprises a plate body and a heating material arranged inside the plate body; the plate body is formed by the butt joint of a mother plate block and a son plate block, at least one groove is evenly arranged on the mother plate block, and the heating material is arranged in the groove; and the heating material is covered by the son plate block, and the son plate block is also connected with the mother plate block fixedly. The invention also discloses a heating device for the spray coating of the solar crucible. The device comprises the heating plate, a fixing frame for fixing the heating plate and a supporting base for supporting the fixing frame. By the heating plate for the spray coating of the solar crucible and the heating device, the aims that the heating temperature is average, the durability is high, the service life is long and the product quality and the production efficiency are enhanced can be realized.

Description

technical field [0001] The invention relates to a solar crucible spraying technology, in particular to a heating plate for solar crucible spraying and a heating device thereof. Background technique [0002] The ingot casting of solar polysilicon uses a crucible as a container for containing crystalline silicon ore. Before ingot casting, a layer of silicon nitride needs to be coated on the surface of the crucible as a release medium after the ingot casting is completed. Silicon nitride is in powder form. In order to make it adhere to the surface of the crucible, it is often sprayed with water. During the spraying process, the pot body of the crucible needs to be heated so that the water evaporates, so that the silicon nitride returns to its original powder form and adheres to the surface of the crucible. [0003] see figure 1 As shown, the crucible is a cubic open container, including five surfaces to be heated 11, and the five surfaces to be heated need to be heated during...
