Description

Technical Field

[0001] This application relates to the technical field of quenching cooling, and particularly to a device and method for constantly maintaining a quenching medium, a computing device, and a storage medium. Background Art

[0002] With the development of technology, there are more and more types of heat treatment quenching media, and the scope of application is getting wider and wider. Commonly used heat treatment media include water-soluble quenching medium PAG and oil-based quenching medium PVP. Quenching media have the advantages of economy, environmental protection, and adjustable cooling rate. By adjusting the concentration, temperature, and microbial inhibition of the quenching medium, any cooling rate between water and oil can be achieved, realizing the advantages of deep hardened layer of heat-treated workpieces, uniform quenching hardness, and less deformation and cracking. Currently, in most application scenarios, a heater is directly inserted into the quenching medium to adjust the temperature of the quenching medium, so as to more precisely control the cooling rate of the workpiece. However, on the one hand, long-term insertion of the heater into the quenching medium will pollute the quenching medium, and on the other hand, it will reduce the service life of the heating element; the concentration of the quenching medium depends on on-site measurement by workers and manual adjustment, with large detection errors, the risk of missed detection, and increased labor intensity; in addition, microorganisms are in an undetected state, and after long-term use of the equipment, the quenching medium is polluted and deteriorated, which harms both the equipment and the product quality. Summary of the Invention

[0003] In view of the above problems in the prior art, this application provides a method and device for constantly maintaining a quenching medium, a computing device, and a storage medium to solve the technical problems that on the one hand, long-term use of directly inserting a heater into the quenching medium will pollute the quenching medium, and on the other hand, it will reduce the service life of the heating element.

[0004] To achieve the above object, the first aspect of this application provides a device for constantly maintaining a quenching medium, including: a temperature control system and a quenching medium storage device;

[0007] Based on the temperature of the quenching medium in the quenching medium storage device detected by the temperature detection element, the first liquid pump, the first electric valve, the second electric valve, the cooling tower and the heater are turned off or on. The quenching medium in the quenching medium storage device is sucked out by the first liquid pump to the heat treatment equipment for quenching. The liquid heated by the heater raises the temperature of the quenching medium before quenching under the condition of non-contact. The quenching medium with increased temperature after quenching flows back into the quenching medium storage device through the first electric valve or the second electric valve and the cooling tower.

[0008] As described above, in this application, the heater is arranged outside the quenching medium storage device. After the quenching medium in the quenching medium storage device is sucked out by the first liquid pump to the heat treatment equipment for quenching, the liquid heated by the heater raises the temperature of the quenching medium before quenching under the condition of non-contact. In this way, it will not pollute the quenching medium after long-term use, nor reduce the service life of the heater.

Specifically, it includes:

[0027] When the microbial quantity of the quenching medium in the quenching medium storage device detected by the microbial detection element is greater than the set allowable value of the microbial quantity, the fourth liquid pump starts, the fifth electric valve opens, and the flow rate of the microbial inhibitor sucked out by the fourth liquid pump from the microbial inhibitor storage device is automatically measured by the third flow meter. When the flow rate of the microbial inhibitor reaches the preset flow rate of the microbial inhibitor, the fourth liquid pump stops and the fifth electric valve closes.

[0028] As a possible implementation of the first aspect, it further includes: a stirrer, which is arranged in the quenching medium storage device and is in a starting state, and is used to neutralize the concentration, temperature, and microbial quantity of the quenching medium at different positions in the quenching medium storage device.

[0056]

Embodiment of the Device for Maintaining the Constancy of the Quenching Medium

[0057] The first embodiment of this application provides a device for maintaining the constancy of the quenching medium, wherein, as Figure 1 shown, it includes: a temperature control system and a quenching medium storage device 10;

[0058] The temperature control system includes a first liquid pump 21, a first electric valve 23, a second electric valve 22, a cooling tower 24, a heater 25, and a temperature detection element 11;

[0059] Among them, the first liquid pump 21 is arranged on one side of the quenching medium storage device 10 ( Figure 1 as shown in), the first electric valve 23 is connected in parallel with the second electric valve 22, the second electric valve 22 and the cooling tower 24 are connected in series, the first electric valve 23, the second electric valve 22, and the cooling tower 24 are arranged on the other side of the quenching medium storage device 10 ( Figure 1 as shown in), the heater 25 is arranged outside the quenching medium storage device 10, and the temperature detection element 11 is arranged inside the quenching medium storage device 10;

[0060] Based on the temperature of the quenching medium in the quenching medium storage device 10 detected by the temperature detection element 11, the first liquid pump 21, the first electric valve 23, the second electric valve 22, the cooling tower 24 and the heater 25 are turned off or on. The quenching medium in the quenching medium storage device 10 is sucked out by the first liquid pump 21 to the heat treatment equipment for quenching. The liquid heated by the heater 25 raises the temperature of the quenching medium before quenching under the condition of non-contact. After quenching, the quenching medium with increased temperature flows back into the quenching medium storage device 10 through the first electric valve 23 or the second electric valve 22 and the cooling tower 24.

[0061] During the quenching process, the quenching medium will come into contact with the high-temperature workpiece, causing the temperature of the quenching medium to gradually increase. Therefore, a cooling tower is provided to cool the quenching medium.

[0062] The liquid heated by the heater 25 can be set as needed, such as water or other suitable heat transfer fluids, without specific limitation.

[0063] The method of "the liquid heated by the heater 25 raises the temperature of the quenching medium before quenching under the condition of non-contact" can be realized by using a heat exchanger. The heater 25 is used to heat the heat transfer liquid in a closed system. This liquid flows through one side of the heat exchanger, while the quenching medium flows through the other side of the heat exchanger. The heat of the heated liquid is transferred to the quenching medium through the heat exchanger, causing the temperature of the quenching medium to rise. At the same time, the two are physically separated to prevent the quenching medium from directly contacting the heater, thus avoiding the corrosion and pollution of the heater by the quenching medium and protecting the quenching medium from the influence of impurities.

[0064] In some embodiments, based on the temperature of the quenching medium in the quenching medium storage device 10 detected by the temperature detection element 11, the first liquid pump 21, the first electric valve 23, the second electric valve 22, the cooling tower 24 and the heater 25 are turned off or on. The quenching medium in the quenching medium storage device 10 is sucked out by the first liquid pump 21 to the heat treatment equipment for quenching. The liquid heated by the heater 25 raises the temperature of the quenching medium before quenching under the condition of non-contact. After quenching, the quenching medium with increased temperature flows back into the quenching medium storage device 10 through the first electric valve 23 or the second electric valve 22 and the cooling tower 24. Specifically, it includes:

[0065] When the temperature detection element 11 detects that the temperature of the quenching medium in the quenching medium storage device 10 is less than the process-set temperature range, the first liquid pump 21 is started, the first electric valve 23 is opened, the heater 25 is started. The first liquid pump 21 sucks out the quenching medium in the quenching medium storage device 10 to the heat treatment equipment for quenching. The liquid heated by the heater 25 raises the temperature of the quenching medium before quenching under the condition of non-contact. When the temperature rises to the preset temperature range, the heater 25 automatically stops;

[0066] When the temperature detection element 11 detects that the temperature of the quenching medium in the quenching medium storage device 10 is within the process set temperature range, the first electric valve 23 is opened, the second electric valve 22 is closed, and the cooling tower 24 stops;

[0067] When the temperature detection element 11 detects that the temperature of the quenching medium in the quenching medium storage device 10 is higher than the process set temperature range, the first electric valve 23 is closed, the second electric valve 22 is opened, the cooling tower 24 is opened, and the quenching medium is cooled when flowing through the cooling tower 24.

[0068] Among them, the process set temperature range is different from the preset temperature range. The preset temperature range is smaller than the process set temperature range. For example, if the process temperature is 25°C - 35°C, then this range is 27°C - 33°C, to prevent the actual temperature of the quenching medium from dropping below the process set temperature during production, resulting in product quality problems.

[0069] Among them, when the temperature of the quenching medium is within the process set temperature range or higher than the process set temperature range, the heater 25 does not start.

[0070] As above, in this application, the heater is arranged outside the quenching medium storage device. After the quenching medium in the quenching medium storage device is sucked out by the first liquid pump to the heat treatment equipment for quenching, the liquid heated by the heater makes the temperature of the quenching medium before quenching rise under the condition of non-contact, which will not cause pollution to the quenching medium after long-term use, nor reduce the service life of the heater. A temperature detection element is also provided, which can detect the temperature of the quenching medium in the quenching medium storage device in real time, realize the stability of the quality of the quenching medium, and ensure the quenching effect of the workpiece.

[0071] In some embodiments, as Figure 1 shown, it further includes: a concentration adjustment system;

[0072] The concentration adjustment system includes a fresh water storage device 30, a second liquid pump 31, a third electric valve 32, a first flow meter 33, a quenching medium stock solution storage device 37, a third liquid pump 34, a fourth electric valve 35, a second flow meter 36, and a concentration detection element 38;

[0073] Among them, a second liquid pump 31, a third electric valve 32, and a first flow meter 33 are sequentially arranged between the fresh water storage device 30 and the quenching medium storage device 10; a third liquid pump 34, a fourth electric valve 35, and a second flow meter 36 are sequentially arranged between the quenching medium stock solution storage device 37 and the quenching medium storage device 10; the concentration detection element 38 is arranged in the quenching medium storage device 10;

[0074] Based on the concentration of the quenching medium in the quenching medium storage device 10 detected by the concentration detection element 38, the second liquid pump 31 and the third electric valve 32 or the third liquid pump 34 and the fourth electric valve 35 are turned on or off, water is added from the clean water storage device 30 and measured by the first flow meter 33, or the quenching medium stock solution is added from the quenching medium stock solution storage device 37 and measured by the second flow meter 36 into the quenching medium storage device 10 to adjust the concentration of the quenching medium.

[0075] In some embodiments, based on the concentration of the quenching medium in the quenching medium storage device 10 detected by the concentration detection element 38, the second liquid pump 31 and the third electric valve 32 or the third liquid pump 34 and the fourth electric valve 35 are turned on or off, water is added from the clean water storage device 30 and measured by the first flow meter 33, or the quenching medium stock solution is added from the quenching medium stock solution storage device 37 and measured by the second flow meter 36 into the quenching medium storage device 10 to adjust the concentration of the quenching medium. Specifically, it includes:

[0076] When the concentration of the quenching medium in the quenching medium storage device 10 detected by the concentration detection element 38 is higher than the process requirement concentration range, the second liquid pump 31 is started, the third electric valve 32 is opened, the amount of water sucked out by the second liquid pump 31 from the clean water storage device 30 is automatically measured by the first flow meter 33. When the amount of water reaches the preset added water amount, the second liquid pump 31 stops and the third electric valve 32 closes;

[0077] When the concentration of the quenching medium in the quenching medium storage device 10 detected by the concentration detection element 38 is lower than the process requirement concentration range, the third liquid pump 34 is started, the fourth electric valve 35 is opened, the amount of the quenching medium stock solution sucked out by the third liquid pump 34 from the quenching medium stock solution storage device 37 is automatically measured by the second flow meter 36. When the amount of the quenching medium stock solution reaches the preset added medium stock solution amount, the third liquid pump 34 stops and the fourth electric valve 35 closes.

[0078] Among them, the amount of clean water / quenching medium stock solution to be added can be calculated according to the liquid volume of the quenching medium in the quenching medium storage device 10. When the amount of clean water measured by the first flow meter 33 reaches the preset added water amount and the amount of the quenching medium stock solution measured by the second flow meter 36 reaches the preset added medium stock solution amount, adding clean water / media stock solution is stopped.

[0079] In addition, when the detected medium concentration is within the process requirement concentration range, the system does not perform any actions and normal workpiece quenching production is carried out. The process requirement concentration range is set based on actual needs.

[0080] As described above, the concentration of the quenching medium in this application is not determined by on-site measurement and manual adjustment by workers. Instead, the addition amounts of fresh water and the quenching medium stock solution are determined by the concentration adjustment system, and the addition amounts of fresh water and the quenching medium stock solution are measured by a flow meter. In this way, the addition of fresh water and the quenching medium stock solution can be automatically adjusted, with small detection errors, no risk of missed detection, and reduced labor intensity.

[0081] In some embodiments, as Figure 1 shown, it further includes: a microorganism inhibition system;

[0082] The microorganism inhibition system includes a microorganism inhibitor storage device 40, a fourth liquid pump 41, a fifth electric valve 42, a third flow meter 43, and a microorganism detection element 44;

[0083] Among them, a fourth liquid pump 41, a fifth electric valve 42, and a third flow meter 43 are sequentially arranged between the microorganism inhibitor storage device 40 and the quenching medium storage device 10; the microorganism detection element 44 is arranged inside the quenching medium storage device 10;

[0084] Based on the microorganism amount of the quenching medium in the quenching medium storage device 10 detected by the microorganism detection element 44, the fourth liquid pump 41 and the fifth electric valve 42 are turned on or off, so that the microorganism inhibitor is added from the microorganism inhibitor storage device 40 into the quenching medium storage device 10 to adjust the microorganism amount of the quenching medium.

[0085] In some embodiments, based on the microorganism amount of the quenching medium in the quenching medium storage device 10 detected by the microorganism detection element 44, the fourth liquid pump 41 and the fifth electric valve 42 are turned on or off, so that the microorganism inhibitor is added from the microorganism inhibitor storage device 40 into the quenching medium storage device 10 to adjust the microorganism amount of the quenching medium. Specifically, it includes:

[0086] When the microorganism amount of the quenching medium in the quenching medium storage device 10 detected by the microorganism detection element 44 is greater than the set allowable value of the microorganism amount, the fourth liquid pump 41 is started, the fifth electric valve 42 is opened, and the flow rate of the microorganism inhibitor sucked out by the fourth liquid pump 41 from the microorganism inhibitor storage device 40 is automatically measured by the third flow meter 43. When the flow rate of the microorganism inhibitor reaches the preset flow rate of the microorganism inhibitor, the fourth liquid pump 41 stops and the fifth electric valve 42 closes.

[0087] In addition, when the microorganism amount of the quenching medium measured by the microorganism detection element is less than the set allowable value of the microorganism amount, the equipment operates normally. The set allowable value of the microorganism amount is set based on actual needs.

[0088] As described above, the microorganism amount of the quenching medium in this application is in a detected state, and the microorganism amount of the quenching medium will be adjusted, so that the medium will not be contaminated and deteriorated after long-term use of the equipment, and will not cause harm to the equipment and product quality.

[0089] In some embodiments, as Figure 1 shown, it further includes: a stirrer 50, which is arranged in the quenching medium storage device 10 and is in a starting state, and is used to neutralize the concentration, temperature and microbial quantity of the quenching medium at different positions in the quenching medium storage device 10.

[0090] Thus, by setting the stirrer in this application, the concentration, temperature and microbial quantity of the quenching medium at different positions in the quenching medium storage device can be neutralized by the stirrer, without manual stirring, reducing the labor intensity of workers.

[0091] In some embodiments, the above control operation can be controlled by a control device (not included in the device for constant maintenance of quenching medium) externally connected to the device for constant maintenance of quenching medium, that is, this application only includes Figure 1 the devices shown and the connection manner of the devices. The device for constant maintenance of quenching medium can also include a control device, that is, this application includes Figure 1 the devices shown and the connection manner of the devices, and at the same time further includes a control device not shown in Figure 1 the display. The corresponding opening / closing of the liquid pump and the electric valve is executed by this control device, and the detection data of the detection element is received.

[0092] In summary, the device for constant maintenance of quenching medium proposed in this application can achieve the following beneficial effects:

[0093] During the quenching process of the workpiece, the temperature, concentration and microbial quantity of the quenching medium are monitored in real time, and are regulated by measures such as heating, cooling, adding clean water, adding the original solution of the quenching medium, adding microbial inhibitors, and continuous stirring, so as to realize the stability of the quality of the quenching medium, ensure the quenching effect of the workpiece, and produce products with high precision, good stability and excellent consistency.
