DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the utility model embodiment will be further described below in conjunction with the drawings.

[0024] Please refer toFigures 1-4 The utility model provides a material high temperature / quenching and annealing and aging analysis integrated device, it includes tubular furnace 1, weighing component 2, fuse assembly 3, vacuum pump 4, cooling tank 5, aerator 6, weighing component 2 sets up at the end of tubular furnace 1, cooling tank 6 sets up at the bottom of tubular furnace 1, aerator 6 is linked with tubular furnace 1, the top of tubular furnace 1 is provided with exhaust port 11, vacuum pump 4 communicates with cooling tank 5, and the detachable sample container 8 is arranged on weighing component 2, and the sample container 8 is arranged in the cavity inside tubular furnace 1, fuse assembly 3 is detachably connected with sample container 8, weighing component 2 is used for real time detection sample container 8 and the mass of heat treatment sample, cooling tank 5 is used for quenching of heat treatment sample, through the controllable fusing of fuse assembly 3 makes sample container 8 in sample fast fall into cooling tank 5, reaches the purpose of rapid cooling.

[0025] In some embodiments, in order to better intuitively obtain the quality change data of the sample, the weighing component 2 can include a balance cavity 21, an electronic suspension scale 22, and a hook 23. The balance cavity 21 is arranged at the end of the tubular furnace 1. The electronic suspension scale 22 is arranged inside the balance cavity 21 and directly above the end of the tubular furnace 1. The hook 23 is arranged at the bottom of the electronic suspension scale 22 and inside the cavity of the tubular furnace 1. The hook 23 is used to hook the sample container 8. When the mass of the sample in the sample container increases, the tension increases, and when the mass decreases, the tension decreases. This can be reflected in the digital electronic suspension scale in real time.

[0026] In some embodiments, in order to more conveniently make the sample in the sample container 8 fall into the cooling tank 5 quickly and achieve the purpose of rapid cooling, the fuse assembly 3 can include a positive electrode lead 31 and a negative electrode lead 32. One end of each of the positive electrode lead 31 and the negative electrode lead 32 is provided with a connecting hook 33 for electrically connecting the sample container 8. The other end of each of the positive electrode lead 31 and the negative electrode lead 32 is electrically connected to the positive electrode 34 and the negative electrode 35 of an external power source, respectively. After the connecting hooks of the positive and negative electrode leads are connected to the circuit, the connection of the fuse and the sample container 8 can be determined by controlling electrical parameters such as voltage, so that the sample container 8 falls into the cooling tank 5 quickly.

[0027] In some embodiments, in order to fuse quickly, the handle of the sample container 8 is a fusible fuse. Whether the fuse is fused or not can be controlled by controlling the current passing through the fuse. The sample container 8 can be a crucible commonly used in the art.

[0028] It should be noted that a direct current circuit device can be arranged at the upper end of the tubular furnace. The current control part of the direct current circuit device can be hooked to the fuse on the sample container by bending the high-temperature-resistant conductive metal wire itself. After the two high-temperature-resistant conductive metal wires are bent 90 degrees at the upper end and bent in an arc shape at the bottom, they can simply hook the fuse provided on the handle of the sample container.

[0029] In some embodiments, in order to facilitate the operation of the staff, while providing a high temperature environment for the sample, and to facilitate the rapid cooling of the sample during subsequent cooling process, the tube furnace 1 is a vertical tube furnace, the top of the cooling tank 5 is connected with the bottom of the tube furnace 1 through a flange, and a ventilation device 6 is installed at the bottom flange of the tube furnace 1 for providing an atmosphere for the heat treatment environment. The ventilation device 6 is communicated with the tube furnace 1 through a gas inlet pipeline 61, and a pressure gauge 62 is arranged on the gas inlet pipeline 61.

[0030] The bottom cooling tank 5 is connected with the cavity of the tube furnace 1 to form a closed cavity in the tube furnace. When the fuse is blown due to excessive current, the sample container 8 falls into the bottom cooling tank 5 due to gravity and contacts with the cooling medium in the cooling tank 5 to achieve the purpose of rapid cooling.

[0031] The vacuum pump 4 located at the right side of the bottom is connected with the cooling tank 5 through a flange and a flexible pipeline. Its function is to ensure that the inside of the tube furnace is in a vacuum state during the whole heating and cooling process.

[0032] In some embodiments, in order to ensure the sealed environment at the bottom, a sealing door 7 can be arranged between the tube furnace 1 and the cooling tank 5. The sealing door 7 is composed of a rotating sealing disc 71 and a rotating control switch 72. The rotating control switch 72 controls the rotation of the rotating sealing disc 71 to realize the opening or closing of the sealing door 7. The sealing door is designed with a rotating control switch. During heat treatment, the rotating control switch is used to control the rotating sealing disc to rotate to the position as shown in FIG. 6, i.e. the sealing door is closed to ensure the sealed environment. During subsequent quenching, the rotating control switch is used to control the rotating sealing disc to rotate to the position as shown in FIG. 7, i.e. the sealing door is opened to ensure that the sample container 8 falls without obstacles.
