When the device is in use, the raw material to be quenched is first placed in the heating mechanism 2 for quenching, and the raw material is taken out after the quenching is completed. At this time, the raw material is placed in the cooling box 3, and the raw material is cooled and cooled by the spraying mechanism 5 provided on the upper end of the cooling box 3. At the same time, the water vapor generated during the cooling process is blown out through the air outlet filter 7 by the fan blades 43 provided inside the filter box 41, so as to increase the cooling speed of the raw material.

[0023] The heating mechanism 2 includes a support plate 21, a first motor 22 and a connecting block 23. Two support plates 21 are symmetrically arranged on the upper end of the bottom plate 1, one of the support plates 21 is connected to the first motor 22 on its side, and the other support plate 21 is rotatably connected to the connecting block 23 on its side.

[0024] Two shells 24 are arranged between the two support plates 21, the output shaft of the first motor 22 is connected to the shell 24 at the lower end through the connecting block 23, and the shell 24 at the lower end is rotatably connected to the shell 24 at the upper end through the connecting shaft 26. Heaters 25 are arranged on the sides of the two shells 24. When the device is in use, the shell 24 is first opened and the raw material is placed inside the shell 24. At this time, the other shell 24 is covered and the shell 24 is locked by bolts. At this time, the first motor 22 and the heater 25 are started, and the first motor 22 drives the shell 24 to rotate, the heater 25 heats the raw material, and the shell 24 rotates so that the raw material is evenly heated.

[0025] Two second motors 42 are symmetrically arranged inside the filter box 41 , and fan blades 43 are arranged at equal angles on the output shafts of the two second motors 42 .

[0026] The spraying mechanism 5 includes a water inlet 51, a water sprinkling frame 52 and a water outlet 53. The cooling box 3 is provided with a water inlet 51 at the upper end, and the cooling box 3 is connected with a water sprinkling frame 52 at the upper end, and the water sprinkling frame 52 is connected to the water inlet 51. The lower end of the water sprinkling frame 52 is provided with water outlets 53 at equal distances. When the device is in use, the heated raw materials are then placed at the upper end of the connecting plate 64 inside the cooling box 3. At this time, water is injected into the water inlet 51, and the water is sprayed through the water outlet 53 opened at the lower end of the water sprinkling frame 52 to cool the raw materials. At the same time, the second motor 42 is started to drive the fan blades 43 to rotate, and the water vapor generated in the water spray cooling process is discharged through the air outlet filter 7, thereby increasing the cooling speed of the raw materials and accelerating the production efficiency.

[0027] A third motor 61 is arranged on the side of the cooling box 3 , and the output shaft of the third motor 61 is connected with a threaded rod 62 , and the threaded rod 62 is arranged on the inner side of the cooling box 3 , and two sliding rods 63 are symmetrically arranged on the inner side of the cooling box 3 .

[0028] The threaded rod 62 is threadedly connected to a connecting plate 64, and a baffle 65 is symmetrically arranged on the upper end of the connecting plate 64. Water guide holes 66 are opened at equal distances on the side of the baffle 65. The connecting plate 64 is slidably connected to the slide rod 63. When the device is in use, the third motor 61 is started during the cooling process to drive the threaded rod 62 to rotate forward and reverse. The threaded rod 62 drives the threaded connecting plate 64 to slide on the side of the slide rod 63. At the same time, the baffle 65 is arranged to prevent the raw materials from falling during the movement. The water guide holes 66 opened on the side of the baffle 65 reduce the resistance generated by the baffle 65 during the movement in the water.

The shell 24 rotates so that the raw material is evenly heated;

[0030] Then, the heated raw materials are placed at the upper end of the connecting plate 64 inside the cooling box 3, and water is injected into the water inlet 51. The water is sprayed out through the water outlet 53 opened at the lower end of the water sprinkling frame 52 to cool the raw materials. At the same time, the second motor 42 is started to drive the fan blades 43 to rotate, and the water vapor generated during the water spraying cooling process is discharged through the air outlet filter 7, thereby increasing the cooling speed of the raw materials and accelerating the production efficiency.

[0031] During the cooling process, the third motor 61 is started and drives the threaded rod 62 to rotate forward and backward. The threaded rod 62 drives the threaded connecting plate 64 to slide on the side of the slide rod 63. At the same time, the baffle 65 is placed to prevent the raw materials from falling during the movement. The water guide hole 66 opened on the side of the baffle 65 reduces the resistance generated by the baffle 65 during the movement of the water in the water. When the water in the cooling box 3 reaches the water outlet located at the upper front end of the cooling box 3, it flows out through the water outlet to avoid the cooling box 3 being filled with water. At the same time, after cooling is completed, all the water can be discharged through the water outlet located at the lower front end of the cooling box 3.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
