Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0022] Please see Figure 1-5This utility model provides a technical solution: a fully automatic ammonia hydrolysis apparatus, including a waste liquid collection bottle 1, a reaction chamber 2, and a control box 3. The inlet of the waste liquid collection bottle 1 is connected to a pipeline (not shown in the figure), which can be quickly connected to a drain port. The reaction chamber 2 is equipped with an ammonia hydrolysis reaction vessel assembly 8, which includes a vessel body and an ammonia hydrolysis vessel cover 10. The vessel body is located inside the reaction chamber 2, and the ammonia hydrolysis vessel cover 10 is located above the reaction chamber 2. A heating diaphragm 23 is provided on the outer wall surface of the vessel body, and a heating plate 24 is connected to the bottom of the vessel body. The upper surface of the pot body is connected to a flange 26. A sealing ring 25 is provided between the ammonia hydrolysis pot body cover 10 and the flange 26. The interior of the pot body is a chamber 11, and a sample rack is installed inside the chamber 11. A pressure gauge 9 is installed on the upper part of the pot body, through which the pressure inside the pot body can be directly observed. A pressure rod assembly is also installed on the ammonia hydrolysis pot body cover 10, including a knob and a metal pressure rod. The knob is a manual operation end, and the force is transmitted through a screw pair when rotated. The two ends of the metal pressure rod are fixed on the flange support, and the middle presses down on the ammonia hydrolysis pot body cover 10 to achieve "three-point" uniform force. When in use, rotating the top knob clockwise causes the metal pressure rod to move downward through the screw drive, uniformly squeezing the ammonia hydrolysis pot body cover 10 and compressing the sealing ring 25 to ensure the overall sealing of the equipment. After opening the cover, rotating the knob counterclockwise causes the pressure rod to retract upward with the screw drive, releasing the downward pressure on the ammonia hydrolysis pot body cover 10.

[0023] The control box 3 has a display screen 4 in the middle of its front wall, a power switch 5, a cooling fan 6, and a buzzer warning light 7 on its side. Inside the control box 3, there is a built-in power supply connected to the power switch 5 and a control board connected to the built-in power supply. The pot body has a second air inlet 18 and a first exhaust / liquid outlet 19, and a thermometer is installed to measure the temperature of the pot body. The first exhaust / liquid outlet 19 is below the second air inlet 18. The reaction chamber 2 has a first air inlet 12 on its side wall surface, located within the reaction chamber. One end of the reaction chamber 2 is connected to a one-way valve 13. A first solenoid valve 14 is provided in the lower middle part of the interior of the reaction chamber 2. A pressure transmitter 15 is provided on the side of the first solenoid valve 14 near the control box 3. An unloading valve 16 is provided on the rear side of the pressure transmitter 15. A second solenoid valve 17 is provided in the lower middle part of the interior of the control box 3. A switch ball valve 20, a second exhaust / liquid port 21 and a third exhaust / liquid port 22 are respectively provided on the side wall of the control box 3. The second solenoid valve 17, the first exhaust / liquid port 19 and the switch ball valve 20 are connected by a three-way connector.

[0024] Working Principle: The first scenario of this device involves adding ammonia: When the solenoid valve 14 is not open and there is no pressure in the pot chamber, open the ammonia hydrolysis pot cover 10, add an appropriate amount of ammonia to the chamber 11, then place the sample to be hydrolyzed onto the sample rack, close the ammonia hydrolysis pot cover 10, and start powering the heating diaphragm 23 and heating plate 24 through the control box 3. When the temperature in the chamber 11 reaches the required temperature for ammonia hydrolysis (generally 90℃), the sample begins the deammoniation reaction. After the sample has completed deammoniation, close the control box 3, depressurize and cool down, remove the sample, close the ammonia hydrolysis pot cover 10, open the first solenoid valve 14 and the second solenoid valve 17 to enter the waste ammonia discharge mode, and discharge the waste ammonia water after the deammoniation reaction into the waste liquid collection bottle 1. A manual waste ammonia discharge mode is also added, which can be achieved by rotating the switch ball 20 to discharge the waste ammonia water. Waste liquid collection bottle 1; Next, the ammonia addition situation: When the first solenoid valve 14 is not open and there is no gas pressure in the pot cavity, open the ammonia hydrolysis pot body cover 10, add an appropriate amount of water to the chamber 11 (mainly to prevent the chamber 11 from dry burning during heating, which would affect the service life of the pot body), then put the sample to be ammonia hydrolyzed on the sample rack, close the ammonia hydrolysis pot body cover 10, and the control box 3 starts to supply power to the heating diaphragm 23 and heating plate 24 for heating. When the temperature in the chamber 11 reaches the temperature required for ammonia hydrolysis (generally 90℃), ammonia is added, and the sample begins to undergo ammonia removal reaction. After the sample has completed ammonia removal, the control box 3 is closed, the pressure is released and the temperature is lowered, the sample is taken out, the ammonia hydrolysis pot body cover 10 is closed, the first solenoid valve 14 and the second solenoid valve 17 are opened to enter the waste liquid discharge mode, and the wastewater after the ammonia removal reaction is discharged into the waste liquid collection bottle 1.
