Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, specifically a quenching tank for rapid cooling of quenching medium. Background Technology

[0002] Quenching is a crucial step in heat treatment. It involves heating a metal workpiece to its austenitizing temperature, holding it at that temperature for a specific time, and then cooling it at a rate greater than the critical cooling rate to obtain a non-diffusion-transformation microstructure. A quenching tank is a container for holding quenching media such as water, brine, oil, or organic solvents. The structure and shape of the quenching tank vary considerably depending on the material, shape, size, batch size, and operational characteristics of the workpiece.

[0003] Since the quenching quality of the workpiece cannot be guaranteed when the temperature of the quenching medium exceeds the normal range, people have improved the cooling efficiency of the quenching medium by setting up cooling chambers, drainage pipes and cooling fans to quickly cool the quenching medium. For example, Chinese utility model patent with announcement number CN217149252U specifically discloses a quenching tank for rapid cooling of quenching medium.

[0004] However, in actual use, it is found that because the quenching medium is in a static state in the cooling chamber, the cooling time is relatively long when relying solely on the cooling fan, which has a certain impact on the quenching process. In addition, after the isolation mesh isolates impurities in the medium, the cleaning space inside the quenching tank is relatively narrow, which reduces the cleaning efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a quenching tank for rapid cooling of the quenching medium, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quenching tank for rapid cooling of a quenching medium includes a quenching tank body and a cooling mechanism. The quenching tank body has an internal isolation mesh and baffles. A lead screw is longitudinally connected to the inner wall of the quenching tank body. One side of the isolation mesh is connected to the lead screw. Several valves are installed on the baffles. A cooling chamber is located on the side of the valves away from the isolation mesh. The cooling mechanism is located on one side of the quenching tank body. A motor is installed on one side of the cooling mechanism. A stirring mechanism is installed inside the cooling mechanism and is fixedly connected to the output shaft of the motor. A water pump is installed on the side of the cooling mechanism away from the motor. A water pump is connected to a suction pipe that extends into the interior of the quenching tank body. Delivery pipes and water inlet pipes are connected to both sides of the cooling mechanism, and the delivery pipes are connected to the interior of the cooling chamber.

[0008] Preferably, a guide rod is fixed longitudinally inside the quenching tank body, and a connecting plate is connected to both the lead screw and the guide rod. The connecting plate is slidably connected to the guide rod, which facilitates the control of the height of the connecting plate inside the quenching tank body.

[0009] Preferably, a protrusion is fixedly connected to one side of the connecting plate, and slots are provided on both sides of the isolation net, with the connecting plate engaging with the slots; this facilitates the assembly and disassembly of the isolation net.

[0010] Preferably, the side of the cooling chamber away from the baffle is machined into an inclined surface, which is inclined towards the direction of the conveying pipe; this facilitates increasing the speed at which the medium flows into the cooling mechanism.

[0011] Preferably, the cooling mechanism has a plurality of heat dissipation holes on the side away from the motor, and the heat dissipation holes are distributed in a ring array on the cooling mechanism to facilitate heat dissipation of the medium.

[0012] Preferably, the end of the stirring mechanism away from the motor is rotatably connected to the inner wall of the cooling mechanism, and stirring rods are fixedly connected to both sides of the stirring mechanism; this facilitates improving the cooling efficiency of the medium.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A quenching tank for rapid cooling of quenching medium, by setting a cooling mechanism on one side of the quenching tank body, the stirring mechanism is driven by a motor to stir the high-temperature medium, and cooling water is injected from the water inlet pipe while the medium is being stirred, thereby increasing the cooling rate of the high-temperature medium. The valve can control the cooling amount of the high-temperature medium, so that the quenching tank body is continuously cooled during use, reducing the impact of cooling on the quenching process.

[0015] 2. This quenching tank for rapid cooling of quenching medium, by setting a screw and a connecting plate inside the quenching tank body, can control the height of the isolation net inside the quenching tank body. This allows the isolation net to isolate impurities in the medium and then move these impurities to the top surface of the quenching tank body. The isolation net can be removed from the connecting plate through a slot, opening up the cleaning space and facilitating the cleaning of the isolation net, thereby improving the cleaning efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a quenching tank for rapid cooling of quenching medium, including a quenching tank body 1 and a cooling mechanism 2;

[0024] The quenching tank body 1 is equipped with an isolation net 6 and a baffle 10. A screw rod 5 is longitudinally connected to the inner wall of the quenching tank body 1. One side of the isolation net 6 is connected to the screw rod 5. Several valves 11 are installed on the baffle 10. A cooling chamber 12 is provided on the side of the valves 11 away from the isolation net 6. A cooling mechanism 2 is located on one side of the quenching tank body 1. A motor 15 is installed on one side of the cooling mechanism 2. A stirring mechanism 16 is installed inside the cooling mechanism 2. The stirring mechanism 16 is fixedly connected to the output shaft of the motor 15. A water pump 3 is installed on the side of the cooling mechanism 2 away from the motor 15. A water pump pipe 4 is connected to the water pump 3. The water pump pipe 4 extends into the interior of the quenching tank body 1. A conveying pipe 8 and a water inlet pipe 7 are connected to both sides of the cooling mechanism 2. The conveying pipe 8 is connected to the interior of the cooling chamber 12.

[0025] In this utility model, a guide rod is fixed longitudinally inside the quenching tank body 1, and a connecting plate 13 is connected to both the lead screw 5 and the guide rod. The connecting plate 13 is slidably connected to the guide rod.

[0026] More specifically, by setting a guide rod inside the quenching tank body 1, it can cooperate with the lead screw 5 to drive the connecting plate 13 to move, making it easy for people to control the height of the connecting plate 13 inside the quenching tank body 1.

[0027] In this utility model, a protrusion is fixedly connected to one side of the connecting plate 13, and slots 14 are provided on both sides of the isolation net 6, and the connecting plate 13 engages with the slots 14.

[0028] More specifically, by opening slots 14 on the isolation net 6, both ends of the isolation net 6 can be installed with the connecting plate 13, making it convenient for people to assemble and disassemble the isolation net 6.

[0029] In this invention, the side of the cooling cavity 12 away from the baffle 10 is machined into an inclined surface, which is inclined toward the conveying pipe 8.

[0030] More specifically, by processing the inner wall of the cooling chamber 12 into a slope, the medium can be guided to flow in the direction of the delivery pipe 8, which facilitates increasing the speed at which the medium flows into the cooling mechanism 2.

[0031] In this utility model, a number of heat dissipation holes 9 are machined on the side of the cooling mechanism 2 away from the motor 15, and the heat dissipation holes 9 are distributed in a ring array on the cooling mechanism 2.

[0032] More specifically, by opening several heat dissipation holes 9 on the cooling mechanism 2, the heat generated by the medium can be discharged, which facilitates the dissipation of heat from the medium.

[0033] In this invention, the end of the stirring mechanism 16 away from the motor 15 is rotatably connected to the inner wall of the cooling mechanism 2, and stirring rods are fixedly connected to both sides of the stirring mechanism 16.

[0034] More specifically, by setting a stirring mechanism 16 inside the cooling mechanism 2, the medium can be driven to rotate, thereby improving the activity efficiency of the medium inside the cooling mechanism 2 and facilitating the improvement of the cooling efficiency of the medium.

[0035] Working principle: When cooling the quenching medium, the valve 11 on the baffle 10 is opened to control a portion of the medium to flow from the quenching tank body 1 into the cooling chamber 12. During the flow of the medium, impurities will remain on the isolation net 6. After being guided by the inclined surface of the inner wall of the cooling chamber 12, the medium will flow to the conveying pipe 8 and enter the cooling mechanism 2 through the conveying pipe 8. Then, the motor 15 installed on the cooling mechanism 2 is started, which drives the stirring mechanism 16 to stir the medium, thereby improving the activity of the medium during cooling. Subsequently, during the stirring process, cooling water is injected into the cooling mechanism 2 through the water inlet pipe 7 to mix with the medium. During the cooling process, the heat of the medium will be discharged from the heat dissipation hole 9. After the cooling is completed, the water pump 3 is started to reintroduce the cooled medium into the quenching tank body 1 through the water pumping pipe 4. When cleaning the impurities on the isolation net 6, the screw 5 is rotated, which causes the connecting plate 13 to move the isolation net 6 upward until the isolation net 6 is at the top surface of the quenching tank body 1. Then, it is separated from the connecting plate 13 through the slot 14, allowing the isolation net 6 to be disassembled and cleaned.
