DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: a water circulation cooling device for heat treatment of steel, comprising a heat treatment pool 1, one end of the heat treatment pool 1 is fixedly connected to a cold water pool 2, a second side plate 8 is fixedly connected below one end of the cold water pool 2, a copper tube 12 is fixedly connected above the second side plate 8, a fan 11 is fixedly connected above the second side plate 8, the fan 11 is arranged at the center of the copper tube 12, a sliding plate 14 is slidably connected to the inside of the heat treatment pool 1, and a movable plate 16 is slidably connected above the sliding plate 14.

[0022] One end of the heat treatment pool 1 is fixedly connected to a water pump 21 , one end of the water pump 21 passes through the outer wall of the heat treatment pool 1 , the other end of the water pump 21 is fixedly connected to a water pump pipe 9 , and the other end of the water pump pipe 9 is fixedly connected to a copper pipe 12 .

[0023] The other end of the copper tube 12 is fixedly connected to a drainage pipe 10 , one side of the cold water pool 2 is fixedly connected to a connecting pipe 5 , and the top of the connecting pipe 5 is fixedly connected to a plurality of groups of spray pipes 6 , which are arranged directly above the cold water pool 2 .

[0024] Based on the first embodiment, the working principle of the water circulation cooling device for heat treatment of steel is as follows: when the water temperature inside the heat treatment pool 1 is to be lowered, the water pump 21 is started, and the water pump 21 will send the hot water inside the heat treatment pool 1 into the inside of the copper tube 12, and then the fan 11 inside the copper tube 12 is started, and the temperature of the hot water will be transferred to the outer wall of the copper tube 12 through the copper tube 12, and then the heat of the outer wall of the copper tube 12 will be taken away by wind through the fan 11. When the hot water passes through the copper tube 12, most of the heat of the water body will be taken away, and then it will be transmitted to the inside of the connecting pipe 5 through the drainage pipe 10, and then sprayed into the inside of the cold water pool 2 through the spray pipe 6. During the spraying process, the water turns into water droplets, and the area of ​​contact with the air is increased, further taking away the heat, and then falls into the inside of the cold water pool 2 and flows into the inside of the heat treatment pool 1 from the outlet 19 on the side of the cold water pool 2, so that the water temperature inside the heat treatment pool 1 remains stable.

[0025] Embodiment 2

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model proposes a water circulation cooling device for heat treatment of steel. Compared with the first embodiment, this embodiment also includes: the other end of the drainage pipe 10 is fixedly connected to the bottom of the connecting pipe 5, one end of the movable plate 16 is fixedly connected to the fixed plate 15, and the upper surface of the sliding plate 14 is provided with a movable plate 16, and the movable plate 16 is slidably connected to the inside of the movable plate 16.

The other end of the connecting rod 17 is rotatably connected to the top of the movable plate 16. The interior of the heat treatment pool 1 is fixedly connected to a limiting rod 22, and the sliding plate 14 is slidably connected to the outer wall of the limiting rod 22.

[0028] A connecting plate 13 is fixedly connected to the outer wall of one side of the sliding plate 14, a first side plate 3 is fixedly connected to one side of the heat treatment pool 1, a stepper motor 4 is fixedly connected to the top of the first side plate 3, a connecting plate 13 is fixedly connected to the top of the stepper motor 4, the connecting plate 13 is slidably connected to the outer wall of the threaded rod 7, a plurality of groups of connecting ports 20 are opened inside the sliding plate 14, and a water outlet 19 is opened on one side of the cold water pool 2.

[0029] The working principle of the water circulation cooling device for heat treatment of steel based on the second embodiment is: when the workpiece needs to be heat treated and cooled, the stepper motor 4 is started, and the rotation of the stepper motor 4 drives the threaded rod 7 to rotate. The outer wall of the threaded rod 7 is slidably connected with a connecting plate 13, and the connecting plate 13 is fixedly connected to the sliding plate 14. When the threaded rod 7 rises with the connecting plate 13, it will bring the sliding plate 14 inside the heat treatment pool 1 to rise along the limit rod 22. When the sliding plate 14 rises, the connecting rod 17 will push the movable plate 16 above the sliding plate 14, so that the movable plate 16 moves along the shape of the sliding groove 23. When the sliding plate 14 rises to the top, the fixed plate 15 just reaches the edge of the sliding plate 14, which is convenient for workers to place the workpiece. Then, the stepper motor 4 is reversed to make the sliding plate 14 descend. During the descent, the connecting rod 17 will drag the movable plate 16 to reset, so that the workpiece remains in the center of the sliding plate 14, so that the workpiece can be better cooled and heat treated, which can replace manual hand-held workpiece heat treatment and better ensure the safety of workers.
