Detailed Description

As shown in fig. 1 to 4, the utility model provides a leaching solution generating device with an air pressure protection function, which comprises a casing 1, a generating tank 2, an exhaust valve 3, a pressure sensor 4 and an electric control board 5, wherein a mounting opening 11 is arranged at the top of the casing 1, an exhaust opening (not marked) is arranged at the top of a tank body of the generating tank 2, the generating tank 2 is arranged in the mounting opening 11, the pressure sensor 4 is electrically connected with the electric control board 5 and is arranged in the casing 1, the exhaust valve 3 is arranged outside the casing 1, the exhaust opening is respectively electrically connected with the exhaust valve 3 and the pressure sensor 4 through air pipes, and the electric control board 5 is also provided with an alarm (not shown).

Specifically, in the actual use process, the tank body of the generating tank 2 is filled with the solution, and in the use process, the exhaust valve 3 is in a closed state, so that the tank body of the generating tank 2 is in a relatively closed state, and the outside air cannot enter the generating tank 2 through the exhaust port, so that the chemical reaction of carbon dioxide in the air and the solution in the generating tank 2 is avoided, and the quality of the produced leacheate is improved.

And along with the continuous generation of the eluent, the air pressure in the tank body of the generating tank 2 is gradually increased, and the pressure sensor 4 detects the air pressure value in the generating tank 2 in real time and sends an air pressure value signal to the main control board. The main control board is integrated with a processor, the processor can compare with a preset value according to the received air pressure value, and after the detected air pressure value is larger than the preset value, the electric control board 5 triggers the alarm to carry out alarm processing.

The display entity of the alarm may adopt a mode of an acoustic alarm or an alarm lamp, etc., and the control mode of the electronic control board 5 integrated with the processor to control the operation of the alarm according to the air pressure value may adopt a conventional alarm control principle, which is not limited and described herein.

Further, after the alarm gives an alarm, the exhaust valve 3 may be used for manual exhaust or may be used for automatic exhaust.

For manual venting, the vent valve 3 is a manual valve, such as a quark valve. After the alarm gives an alarm, the user manually opens the exhaust valve 3 to deflate and then closes the exhaust valve 3 to avoid the outside air from entering the generating tank 2 after the exhaust is completed.

For automatic exhaust, the exhaust valve 3 is a normally closed gas electric valve, and the normally closed gas electric valve is electrically connected with the electric control plate 5. Specifically, the exhaust valve 3 adopts an electric valve, and the exhaust valve 3 is normally closed under normal conditions, so as to prevent external air from entering the generating tank 2. After the alarm gives an alarm, the electric control board 5 controls the exhaust valve 3 to automatically exhaust, so that the automatic design is realized. Meanwhile, for operators in a laboratory, the operation state of the eluent generating device can be further observed according to the prompt of the alarm, so that the eluent generating device is turned off in time when the exhaust valve 3 fails and cannot exhaust automatically.
