Water-cooled crucible

Abstract

The invention discloses a water-cooled crucible which comprises a crucible body and a base. A material tank is formed in the center of the top of the crucible body, and the base is fixedly connected with the bottom of the crucible body. A material tank circumference water-cooled mechanism comprises an inward recessed water tank formed in the bottom of the material tank of the crucible body, a lower opening of the water tank is closed by the base, a flow guide vertical column is fixedly arranged in the water tank, and an overflow hole is formed in the upper end or the lower end of the flow guide vertical column, so that the water tank is matched with the overflow hole to form a vertically tortuous water channel. According to the water-cooled crucible, runners in different forms are designed at different positions, the crucible is highly targeted, the water-cooled effect and uniformity of the water-cooled crucible can be effectively ensured, two runner designs are weldless in the crucible body, potential safety hazards of water leakage are avoided, device reliability is improved, machining cost is reduced, a water hole is drilled, a water guide pipe is embedded, internal and external circulation of a sleeve is performed, so that a circulation water channel is formed, machining accuracy can be ensured, the cooling area of the water channel can be flexibly adjusted by adjusting the diameter and the position of the water hole and the width of the water tank, so that the cooling area is increased, and the requirements of different heat loads are met.

Description

technical field [0001] The invention relates to a crucible, in particular to a water-cooled crucible. Background technique [0002] Vacuum metal smelting and purification technology. In the evaporation system, a water-cooled welded copper crucible is used as the carrier of the evaporation heat source. Copper has very good thermal conductivity. Under water-cooling conditions, it can well reduce its own temperature and ensure performance. The existing cooling water channel generally adopts the water channel structure of bottom-in and top-out. [0003] Chinese patent CN 204987858U discloses a water-cooled crucible for an electron beam melting furnace, which includes a base, the upper end of the base forms a convex ring, the outer water jacket and the lower end of the jacket are connected to the top surface of the convex ring, and the lower end of the inner water jacket is inserted into the convex ring. And connected with the base, the outer water jacket, the jacket, and the in...

Problems solved by technology

[0004] Although the above structure overcomes the temperature of local evaporation, the formation of the entire waterway needs to be realized by vacuum brazing, which has high processing costs, is limited by the heat load, and has potential safety hazards of water leakage, which affects the reliability of the evaporation system.
