[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figure 1-2, the present utility model provides a technical solution: a quenching liquid temperature detection and control system, including an outer box body 1 and an inner box body 2. The inner box body 2 is arranged in the cavity of the outer box body 1. An air inlet pipe 3 is provided at the upper end of the outer box body 1, and the outer end of the air inlet pipe 3 is connected to a refrigeration compressor 4. A plurality of cooling pipes 5 penetrate through the cavity of the inner box body 2, and both the upper and lower ends of the cooling pipes 5 communicate with the inner cavity of the outer box body 1. A liquid inlet pipe 6 and a liquid outlet pipe 7 are respectively provided on the side wall and the bottom end of the inner box body 2, and both the liquid inlet pipe 6 and the liquid outlet pipe 7 extend outside the outer box body 1. An exhaust pipe 8 is provided at the bottom end of the outer box body 1. A temperature sensor 9 is arranged in the cavity of the inner box body 2. The temperature sensor 9 is electrically connected to a controller 10, and the controller 10 is also electrically connected to the refrigeration compressor 4. The controller 10 uses an STM32F051 chip, which is a 32-bit MCU with powerful functions and relatively low power consumption. In the standby mode, the working current is only a few microamperes. The temperature acquisition adopts an intermittent method. During the idle time, the terminal is basically in the standby state. The time interval for acquiring the temperature can be adjusted at any time according to the data measured by the temperature sensor 9 to meet the requirements of temperature acquisition.

[0017] Specifically, a support frame 11 is provided on the lower side of the outer box body 1, and a reinforcing rib 12 is provided in the middle of the support frame 11.

[0018] Specifically, a solenoid valve 13 is provided on the air inlet pipe 3, and the solenoid valve 13 is electrically connected to the controller 10. A solenoid valve is an industrial device controlled by electricity magnetism. It is a basic automation component used to control fluids and belongs to an actuator. A solenoid valve can cooperate with different circuits to achieve the expected control, and both the control accuracy and flexibility can be guaranteed. There is a sealed cavity in the solenoid valve, and through holes are opened at different positions. Each hole leads to a different oil pipe. In the middle of the cavity is a valve body, and on both sides are two electromagnets. Whichever side the magnet coil is energized, the valve body will be attracted to that side. By controlling the movement of the valve body, different oil discharge holes can be blocked or leaked. The oil inlet hole is normally open, and hydraulic oil will enter different oil discharge pipes, and then the piston of the oil cylinder is pushed by the pressure of the oil. The piston drives the piston rod, and the piston rod drives the mechanical device to move. In this way, the mechanical movement is controlled by controlling the current of the electromagnet.

[0019] Specifically, an air extraction pump is provided at the outer end of the exhaust pipe 8, which means it has an air extraction nozzle and an exhaust nozzle for one inlet and one outlet, and a vacuum or negative pressure can be continuously formed at the inlet; a slightly positive pressure is formed at the exhaust nozzle; it is an instrument with the working medium mainly being gas, often called a micro air extraction pump or a micro vacuum pump.

[0020] Specifically, the controller 10 is electrically connected to a display screen 14, a transmission module 15, and a power supply 16. The transmission module 15 includes an RS485 module, a wired network module, and a wireless module. The power supply 16 is a battery or connected to the mains power. Considering the power consumption of the terminal and the particularity of the power system, the wireless module adopts a low-power distributed wireless mobile ad-hoc network technology, operates in the 433M free frequency band, has a sleep current of 0.5uA, and a wide operating voltage range of 2.0 - 3.6V. In this way, even when the battery voltage is relatively low, normal wireless communication can be ensured. After the system device is powered on, initialization is performed. The data receiver establishes a network and remains in a network monitoring state all the time. The terminal searches for the network signal, finds the network established by the data receiver, and sends a request to join the network command, waiting for approval to join the network. The data receiver will establish a mapping table for the terminals approved to join the network for communication establishment. The terminals in the network are both terminal devices and routing devices, and can implement data transmission and routing functions. All terminal device data is finally transmitted to the PC through the data receiver for analysis and processing. The acquisition system configures parameters for each terminal in the system wirelessly, including cold air delivery, date and time, and data acquisition time.

The quenching liquid enters the inner box 2 through the liquid inlet pipe 6, and the quenching liquid in the inner box 2 is cooled by the cold air in the outer box 1 and the cooling pipe 5. The setting of the cooling pipe 5 increases the cooling area, achieves the purpose of rapid cooling, meets the production requirements, and ensures product quality.
