Embodiment Construction
[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with illustrations and specific embodiments.
[0015] Such as figure 1 , figure 2 , image 3 As shown, the cover plate for the polysilicon ingot crucible proposed by the present invention comprises a cover plate body 1, an air inlet 2 is provided in the cover plate body, and an air flow baffle 3 is installed under the cover plate body, and the air flow baffle 3 is arranged below the cover plate body. The position corresponds to the position of the air intake hole, and there is a gap for the air flow to discharge between the cover plate body and the air flow baffle. In this embodiment, both the air intake hole and the airflow baffle are circular, the central axis of the air intake hole coincides with the central axis of the airflow baffle, and the diameter of the airflow b...
