Description

TECHNICAL FIELD

[0001] The utility model relates to ammonia gas decomposition technical field, concretely is ammonia lysimeter. BACKGROUND

[0002] After DNA synthesis, the synthesized oligonucleotide chain must be chemically cut off from the support. Fresh concentrated ammonia is commonly used to break the ester bond between the linking compound and the initial nucleoside on the CPG. The ammonia lysis process is an important part of DNA synthesis and is an important factor affecting primer quality, yield, and purity. Currently, gas-phase high-pressure ammonia lysis devices, ammonia lysis pots, are used on the market. The mechanism is to heat ammonia vapor to achieve ammonia lysis effect. The ammonia lysis pot generally uses high temperature and high pressure mode, there is a large amount of ammonia vapor in the tank body, and the pressure is very high. Therefore, there is a great safety hazard, improper operation can easily cause danger, so the safety pressure relief device is a key component, and the opening and closing pressure points must be safe and reliable.

[0003] For example, a DNA ammonia lysimeter with publication number CN217677350U includes an ammonia lysimeter main body, a control box fixedly arranged on one side of the top end of the ammonia lysimeter main body, the top end of the control box is inclined, a control panel is arranged on the top end of the control box, a pressure gauge is fixedly arranged on the front of the ammonia lysimeter main body, air joints are arranged on both sides of the ammonia lysimeter main body, tail gas collection bottles and ammonia tanks are fixedly connected to the two air joints through hoses, a cavity is formed in the top end of the ammonia lysimeter main body, and three movable grooves are formed in the edge of the cavity. When the DNA ammonia lysimeter is used, the DNA synthesis plate is placed on the top end of the heater, then the sealing cover is placed on the top end of the bottom cover seat, the bolt is rotated into the through groove, and the fixed block is rotated to firmly fix the sealing cover on the bottom cover seat, so that the inside of the ammonia lysis barrel maintains high airtightness, and the ammonia lysis of DNA can be carried out. The device can effectively improve the safety and ammonia lysis efficiency during ammonia lysis.

[0004] The above-mentioned patent can improve the safety and ammonia lysis efficiency during ammonia lysis. Currently, most traditional pressure relief devices of the same type on the market use micro-activated adjustable pressure relief valves or adjustable check valves. When the set pressure is reached, the spring automatically releases pressure, and when the pressure drops to a safe range, it is turned off again. The problems of traditional pressure relief devices mostly occur in the pressure relief point, which is easy to be stuck and not to release pressure, the sealing ring is corroded and stuck, the pressure relief valve action point is not sensitive due to long-term high temperature and high pressure corrosion working condition environment, etc. Most ammonia lysimeters are designed for bottom drainage. Because the ammonia lysis working pressure is relatively high, the bottom drainage method has the risk of leakage, which cannot be detected in time, leading to pressure fluctuation and safety hazards. The operator cannot predict whether the body can be safely operated before ammonia lysis work.

[0005] Therefore, we propose an ammonia lysimeter to solve the above-mentioned problems. CONTENT OF THE UTILITY MODEL

[0022] The exhaust assembly 7 comprises an exhaust pipe, a safety pressure relief valve, an impurity filtering device and a buzzer alarm, the impurity filtering device is used for removing fine impurities carried by the gas flow, preventing the safety pressure relief valve from being blocked, and triggering the buzzer alarm when leakage detection is abnormal.

[0023] The feeding assembly 2 comprises fixed rods 21 fixedly installed at two sides of an upper end of the cover 12, and a connecting plate 22 fixedly and jointly installed between the two fixed rods 21.

[0024] A fixed block 23 is fixedly installed at a middle portion of an upper end of the connecting plate 22, a rotating rod 24 is rotatably installed in the fixed block 23, and a connecting block 25 is threadedly installed at a lower end of the rotating rod 24.

[0025] An active cover assembly 3 is installed at an upper end of the ammonia-lysis barrel 14.

[0026] Connecting rods 32 are fixedly installed at two sides of an upper end of the active cover 31, and upper ends of the two connecting rods 32 are fixedly connected with the connecting block 25.

[0027] In the embodiment, the exhaust assembly 7 and the liquid outlet pipe 6 are discharge ports at the end of ammonia-lysis, the air inlet pipe 5 is used for feeding ammonia gas, the safety pressure relief valve in the exhaust assembly 7, and the pressure and temperature detection device 8 are used for sensing and displaying the cavity pressure and detecting and displaying the temperature in the cavity.

[0028] The instrument has two working modes.

[0029] Firstly, the product is put in before work, and the rated pressure clean inert gas is fed through the air inlet pipe 5, and all inlet and outlet valves are closed.

[0030] 1. Ammonia water working mode: ammonia water and a small amount of deionized water are directly added into the ammonia-lysis barrel 14, the inlet and outlet valves are closed, the ammonia-lysis barrel 14 is heated to a set temperature by the heating ring 13 and is kept at the set temperature for a certain time.

[0031] 2. Ammonia gas working mode: pressure ammonia gas is fed through a three-way valve, the valve is closed after the pressure ammonia gas reaches a certain pressure according to a pre-set process, and then the ammonia-lysis barrel 14 is heated to a set temperature and is kept at the set temperature for a certain time.

[0032] 3. The process after heating and heat preservation is the same for both working modes. After slowly releasing the pressure to zero through the exhaust port, clean compressed air or nitrogen is introduced through the air inlet to purge the chamber and cool it down, or it is allowed to cool down naturally. After reaching a safe temperature and pressure, the cover is opened and the product is taken out.

[0033] Complete process flow: Under normal temperature and pressure, open the movable cap 31, put the primer to be synthesized into the ammonia hydrolysis tank 14, seal it, and perform an automatic leak test. After the test is passed, set the required temperature and pressure for the process, turn on the heating switch, and automatically heat the ammonia hydrolysis tank 14 through the heating ring 13. When heating is complete, the instrument will indicate that the heating is complete. Turn off the heating and slowly open the safety pressure relief valve in the exhaust assembly 7 to release the pressure to zero. After the temperature is allowed, open the tank and take out the product. If the pressure test fails, the buzzer alarm will sound. After checking and eliminating the leak point, repeat the above process to hydrolyze the product.

[0034] This invention avoids the difficulty in detecting minor leaks in ammonia hydrolysis instruments and the risk of timely discovery of leaks, making it safer and more reliable for personnel operation.
