The implementation principle of the solid solution heat treatment quencher in the embodiment of the application is as follows: the shielding gas in the collection cavity 14 is conveyed to the exchange cavity 15 under the action of the shielding gas conveying device 20, the shielding gas cooling device 30 in the exchange cavity 15 cools and cools the shielding gas entering the exchange cavity 15, the shielding gas after cooling enters the air blowing pipe 50 through the right end of the air blowing pipe 50 and is sprayed out to the cooling cavity 13 through the air jet hole 51 and attached to the sleeve 40, so that the shielding gas in the sleeve 40 and the sleeve 40 is cooled and is heated up, the shielding gas after heating up enters the collection cavity 14 through the shielding gas outlet hole 132, and the circulation is performed in sequence.
The workpiece 90 after the solution heat treatment directly passes through the connecting pipe 60 after coming out from the outlet of the solution heat treatment equipment, the protective gas in the connecting pipe 60 takes away a part of heat of the workpiece 90 while protecting the workpiece 90, the workpiece 90 is primarily cooled, then the workpiece 90 enters the shell 10 through the workpiece inlet 11 and passes through the sleeve 40 to be cooled again, and then the cooled workpiece 90 moves out of the shell 10 through the workpiece outlet 12 to finish cooling.
Example 2:
referring to fig. 7, the difference from embodiment 1 is that the blow pipe 50 includes an arc part 52 and a guide part 53. Arc portion 52 is the arc platelike setting, and the quantity of guide part 53 is two, and two guide part 53 are located the both sides of arc portion 52 respectively, and two guide part 53 are close to from arc portion 52 to the direction of sleeve pipe 40 gradually, and fumarole 51 is located between two guide part 53 to the speed when making the protection gas spout from fumarole 51 is faster.
The solution heat treatment quencher according to the embodiment of the application can be used for rapidly cooling the workpiece 90 after solution heat treatment and can also be used for rapidly cooling the workpiece 90 after other heat treatments.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
