[0031] The present invention provides as Figures 1 to 5An intelligent temperature-controlled heat treatment system for bearing steel is shown, including a box body 1 with a partition 2 slidably arranged inside. The partition 2 divides the interior of the box body 1 into a treatment chamber 10 and an air chamber 11. Among them, the treatment chamber 10 is located above the air chamber 11, and the interior of the treatment chamber 10 is filled with cooling water.

[0032] Referring to Figure 1 As shown in the figure, support columns 20 are fixedly installed at the four corners of the bottom of the box body 1, and the support columns 20 are provided to support the box body 1.

[0033] During specific use, a sealing ring is provided on the outer wall of the partition 2 to improve the sealing between the partition 2 and the inner wall of the box body 1, and at the same time reduce the wear of the partition 2 during up and down sliding.

[0034] In addition, a temperature sensor 31 and a refrigeration device are fixedly installed on the top of the partition 2. The refrigeration device includes structures such as a semiconductor refrigeration sheet, which is used to cool the cooling water inside the treatment chamber 10. The temperature sensor 31 and the refrigeration device cooperate,

[0035] Specifically, a controller can be set to be connected between the refrigeration device and the temperature sensor 31. When the temperature sensor 31 detects that the temperature exceeds the set threshold, this information is transmitted to the controller, and the controller controls the refrigeration device to start. The controller and its control principle are common existing technologies and will not be elaborated here; the temperature sensor 31 and the refrigeration device cooperate to achieve the effect of intelligent temperature control.

[0036] A power supply device can also be provided at the bottom of the partition 2 to supply power to the temperature sensor 31 and so on. The power supply device includes structures such as a storage battery.

[0037] Referring to Figure 2 As shown in the figure, a rotating shaft 3 is rotatably connected to the partition 2. The top of the rotating shaft 3 is fixedly connected to a bracket 4. There are multiple brackets 4. A support rod 5 is fixedly connected to the bracket 4. The top end of the support rod 5 is fixedly connected to a support ring 6. A treatment basket 7 is inserted into the inside of the support ring 6. A motor 9 is fixedly connected to the bottom of the partition 2, and the rotating shaft 3 is fixedly connected to the driving shaft of the motor 9. The bearing steel is placed inside the treatment basket 7. The motor 9 drives the bracket 4 to rotate through the rotating shaft 3, and the bracket 4 drives the treatment basket 7 to rotate around the axis of the rotating shaft 3 by using the support rod 5 and the support ring 6, so as to achieve the effect of making the bearing steel fully and quickly contact with the cooling water, quickly cooling, and improving work efficiency.

[0038] And a plurality of through grooves 8 are formed in the treatment basket 7. The through grooves 8 are provided to make the treatment basket 7 in a hollow shape, facilitating the full and quick contact between the bearing steel and the cooling water.

[0039] The treatment basket 7 is fixed inside the support ring 6 by an insertion method. After cooling, the bearing steel can be taken out by using the treatment basket 7.

[0040] Refer to Figure 2 As shown, an electric cylinder 19 is fixedly connected to the bottom of the box body 1, and the partition plate 2 is fixedly connected to the telescopic end of the electric cylinder 19. When the telescopic end of the electric cylinder 19 extends, it drives the partition plate 2 to slide upward inside the box body 1. When the telescopic end of the electric cylinder 19 retracts, it drives the partition plate 2 to slide downward inside the box body 1. The partition plate 2 slides up and down inside the box body 1, driving structures such as the treatment basket 7 to move up and down synchronously, so that the treatment basket 7 will move up and down while rotating around the axis of the rotating shaft 3, further improving the cooling efficiency.

[0041] Considering that floating impurities will be generated during the quenching and cooling of bearing steel, and the impurities are at the water surface. If the bearing steel is directly taken out, it is easy for the impurities to adhere to the bearing steel, affecting subsequent use. A sliding channel 12 is opened on the side wall of the box body 1. The sliding channel 12 communicates with the treatment chamber 10. A separation disk 13 is slidably arranged inside the sliding channel 12. The upper surface of the bottom of the separation disk 13 is inclined, and the end located outside the treatment chamber 10 is inclined downward. A connecting pipe 14 is connected to the end located outside the treatment chamber 10.

[0042] A first inner groove 15 is opened at the top of the sliding channel 12. A first electric push rod 16 is fixedly connected to the inner wall of the first inner groove 15. A first partition block 17 is fixedly connected to the telescopic end of the first electric push rod 16. The first partition block 17 cooperates with the sliding channel 12.

[0043] During the cooling stage, the liquid level of the cooling water is lower than the sliding channel 12, and the telescopic end of the first electric push rod 16 is controlled to extend, driving the first partition block 17 to move downward and closing the sliding channel 12. The separation disk 13 fits on the side wall of the first partition block 17. When the bearing steel needs to be taken out, the telescopic end of the electric cylinder 19 is controlled to extend, driving the partition plate 2 to slide upward inside the box body 1, so that the liquid level of the cooling water is higher than the sliding channel 12. The telescopic end of the first electric push rod 16 is controlled to retract, and the first partition block 17 retracts into the first inner groove 15. The operator quickly controls the separation disk 13 to slide toward the inside of the box body 1, and the separation disk 13 abuts against the inner wall of the box body 1. Since the upper surface of the bottom of the separation disk 13 is inclined, and the end located outside the treatment chamber 10 is inclined downward, the cooling water at the liquid level is discharged through the separation disk 13 and the connecting pipe 14, and at the same time, the impurities at the liquid level are discharged. After the cooling water at the liquid level is completely discharged, the telescopic end of the electric cylinder 19 is controlled to retract, driving the partition plate 2 to slide downward inside the box body 1, and the cooling water drops. Then, the separation disk 13 is controlled to slide toward the outside of the box body 1, so that when the bearing steel is taken out, the situation where impurities adhere to the bearing steel will not occur.

[0044] By arranging structures such as the partition plate 2, the treatment basket 7, and the separation disk 13, when the bearing steel is driven to rotate around the axis of the rotating shaft 3, it will also move up and down, ensuring rapid cooling, and separating and discharging the impurities at the liquid level, so that when the bearing steel is taken out, there will be no situation where impurities adhere to the bearing steel, improving work efficiency.

[0045] Moreover, the up-and-down sliding of the partition plate 2 can not only control the liquid level position, but also push and scrape the impurities remaining on the inner wall of the lower half of the box body 1 upward, facilitating the operator to clean the inside of the box body 1.

[0046] Refer to Figure 4 As shown in the figure, a support plate 18 is fixedly connected to the outer wall of the box body 1, and the separation disk 13 is attached to the top of the support plate 18. The support plate 18 is provided to support the separation disk 13, ensuring the stability of the sliding of the separation disk 13.

[0047] Considering that waste gas will be generated during the quenching and cooling process, in order to realize the treatment of waste gas, an upper hole 30 is opened on the side wall of the box body 1. The upper hole 30 is located below the separation disk 13, and the upper hole 30 communicates with the treatment chamber 10. A lower hole 23 is opened on the side wall of the box body 1, and the lower hole 23 communicates with the air chamber 11. The upper hole 30 and the lower hole 23 are connected by a trachea 21. A filtering and purification device 22 is provided on the trachea 21, and the filtering and purification device 22 is fixedly connected to the outer wall of the box body 1. The filtering and purification device 22 includes structures such as a filter screen and an activated carbon plate, which can filter and purify the waste gas, and the operator can regularly repair and replace the inside of the filtering and purification device 22.

[0048] A first one-way valve 24 is fixedly installed inside the lower hole 23. The first one-way valve 24 allows the gas inside the trachea 21 to enter the air chamber 11 through the lower hole 23 without reverse flow; an exhaust hole 25 is opened at the bottom end of the box body 1, and the exhaust hole 25 communicates with the air chamber 11. A second one-way valve 26 is fixedly installed inside the exhaust hole 25. The first one-way valve 24 allows the gas inside the air chamber 11 to be discharged through the exhaust hole 25 without reverse flow.

[0049] During actual use, when the partition plate 2 slides upward inside the box body 1, it will suck the waste gas inside the treatment chamber 10 through the trachea 21 and the upper hole 30, and the waste gas enters the inside of the filtering and purification device 22 for filtering and purification treatment; when the partition plate 2 slides downward inside the box body 1, it will cause the gas inside the air chamber 11 to be discharged through the exhaust hole 25, realizing the effect of waste gas treatment.

[0050] Moreover, during this process, when the partition plate 2 slides upward inside the box body 1, the liquid level of the cooling water will not exceed the bottom end of the upper hole 30, so that the cooling water will not enter the inside of the upper hole 30, and the separation disk 13 closes the top of the box body 1, ensuring the suction efficiency.

[0051] A second inner groove 27 is formed at the top of the upper hole 30. A second electric push rod 28 is fixedly connected inside the second inner groove 27. A second partition block 29 is fixedly connected to the telescopic end of the second electric push rod 28, and the second partition block 29 cooperates with the upper hole 30. When the telescopic end of the second electric push rod 28 is extended, the second partition block 29 will be driven to move downward to close the upper hole 30. During the cooling process, the upper hole 30 is closed through the cooperation of the second electric push rod 28 and the second partition block 29, while the upper hole 30 is opened when treating waste gas.

[0052] The present invention also discloses an intelligent temperature-controlled heat treatment process for bearing steel, which is applied to the above-mentioned intelligent temperature-controlled heat treatment system for bearing steel, and further includes the following operating steps:

[0053] S1. Place the bearing steel inside the treatment basket 7 to enable the bearing steel to come into full and rapid contact with the cooling water.

[0054] S2. The cooling water at the liquid level is discharged by the separation disc 13 and the connecting pipe 14, and at the same time, the impurities at the liquid level are discharged.

[0055] S3. Use the partition plate 2 to slide up and down inside the box body 1 to treat the waste gas.
