As shown in fig. 1-4, one embodiment of the solution furnace apparatus of the present invention. The solid solution furnace equipment of the embodiment comprises a furnace body 1, a furnace cover 2, a water tank 3, a sealing curtain 4 and a first air blowing pipe 5. The furnace body 1 is hollow, the inner space of the furnace body 1 is used as a working space for heating and preserving heat of the solid solution material 6, and the furnace body is provided with a vacuumizing system for vacuumizing the furnace, a gas supply system for filling protective gas into the furnace, a heating system for heating the furnace, a pressure detection system for controlling the air pressure in the furnace and a strong wind convection system in the furnace, and the solid solution material 6 placed in the furnace is heated and preserved according to a set heating and preserving process by the systems, which is the prior art and is not repeated herein.

In this embodiment, the lower end of the furnace body 1 is provided with an opening 101, and the furnace cover 2 is used for closing or opening the opening 101. Referring to fig. 1, when the furnace cover 2 closes the opening 101, the inner space of the furnace body 1 is also sealed, and at this time, the solid solution material 6 placed in the furnace body 1 can be heated and heat-insulated. Referring to fig. 3, when the furnace cover 2 opens the opening 101, the solid solution material 6 heated and kept in the furnace body 1 can fall out of the furnace from the opening 101, i.e. the opening 101 is used as a discharge port for the solid solution material 6 in the furnace body 1 to pass through. Preferably, solid solution material 6 is placed on the rack 7 and is fed into and out of the furnace with the rack 7, and the opening 101 is allowed to pass through the rack 7.

The water tank 3 is arranged below the furnace body 1, and the furnace body 1 is erected on the bracket 8, so that an installation space is arranged below the furnace body 1, and the water tank 3 is arranged in the installation space. The water tank 3 is filled with deionized water for cooling the solid solution material 6 after the heating and the heat preservation are completed. Referring to fig. 3, the upper end of the water tank 3 is opened and spaced opposite to the opening 101 at the lower end of the furnace body 1, and then the solid solution material 6 falling out of the furnace from the opening 101 at the lower end of the furnace body 1 can directly fall into the water tank 3. Therefore, the tapping and water-in time of the solid solution material 6 can be effectively shortened, the rapid water-in of the solid solution material 6 after tapping can be realized, the surface temperature of the solid solution material 6 is basically unchanged, and the uniformity and the reliability of the solid solution treatment of the solid solution material 6 are ensured. In this embodiment, by designing the interval between the water tank 3 and the furnace body 1, the tapping and water-in time of the solid solution material 6 can be within 5 seconds, and compared with the prior art, the tapping and water-in time of the solid solution material 6 is greatly shortened, and the surface temperature of the solid solution material 6 can be basically not reduced.

The sealing curtain 4 is arranged on the periphery of an opening 101 at the lower end of the furnace body 1, as shown in fig. 2 and 3, the sealing curtain 4 is used for connecting the furnace body 1 and the water tank 3 and enclosing a sealed space 9, and then a falling path from the tapping of the solid solution material 6 from the opening 101 at the lower end of the furnace body 1 to the water entering into the water tank 3 is positioned in the sealed space 9, namely, the tapping and water entering process of the solid solution material 6 is carried out in the sealed space 9. The first air blowing pipe 5 is arranged on one side of the sealing curtain 4 close to the opening 101, the first air blowing pipe 5 is used for introducing protective gas into the sealing space 9, so that air in the sealing space 9 can be blown away, and a protective gas atmosphere is formed in the sealing space 9, so that the process of discharging and charging water of the solid solution material 6 is carried out in the protective gas atmosphere, and the solid solution material 6 is not contacted with the air, so that oxidation is not generated. The first gas blowing pipe 5 is capable of reducing the oxygen content in the sealed space 9 to a very low value by introducing a protective gas into the sealed space 9, but a large amount of protective gas is required to reduce the oxygen content in the sealed space 9 to zero, which is not beneficial to cost control, so that in practical operation, a trace amount of oxygen content in the sealed space 9 can be allowed to exist, for example, the oxygen content in the sealed space 9 is reduced to below 10%, at this time, slight oxidation can be generated when the solid solution material 6 is discharged from the furnace and filled with water through the sealed space 9, and in order to eliminate the slight oxidation of the surface of the solid solution material 6, an environment-friendly reducing agent can be added into the water in the water tank 3 to reduce the slight oxidation of the surface of the solid solution material 6, so that the solid solution material 6 is not oxidized after being cooled out of the water, and is not oxidized after being stored for a short time, which is beneficial to subsequent processing and storage.

Therefore, the solid solution furnace equipment of the embodiment can realize long-time high heat preservation, full solid solution, quick tapping and water feeding of the solid solution material 6 without oxidation, so that the solid solution property of the solid solution material 6 is more uniform and reliable, the surface property of the solid solution material 6 is improved, the surface treatment of an oxide layer is not required to be removed, and the process steps and materials are saved, thereby improving the production efficiency, reducing the process waste, reducing the energy consumption, improving the product quality and simultaneously reducing the production cost.
