One end of the liquid outlet pipe 15 is connected to the storage tank A1, and the liquid outlet pipe 15 is provided with a manual ball valve A2, a liquid transfer pump A3, a manual ball valve B4 and a pneumatic ball valve A5; the manual ball valve A2 is adjacent to the storage tank A1, the liquid transfer pump A3 is located between the manual ball valve A2 and the manual ball valve B4, and the pneumatic ball valve A5 is adjacent to the manual ball valve B4; the liquid outlet pipe 15 The tube body is connected with one end of the down-liquid pipe 6, one end of the liquid transfer pipe 12 and one end of the compressed air pipe 14 in sequence, the other end of the down-liquid pipe 6 is connected to the storage tank B7, and the other end of the liquid transfer pipe 12 is connected to the side of the lower end of the storage tank B7; a manual ball valve F16 is provided on the down-liquid pipe 6, a manual ball valve E13 is provided on the compressed air pipe 14, and a manual ball valve C8, a liquid transfer pump B9, a manual ball valve D10, a pneumatic ball valve B11 and a manual ball valve G17 are provided on the liquid transfer pipe 12; the manual ball valve C8 is adjacent to the storage tank B7, the liquid transfer pump B9 is located between the manual ball valve C8 and the manual ball valve D10, and the pneumatic ball valve B11 is adjacent to the manual ball valve D10; the positions of the manual ball valve F16, the manual ball valve G17 and the manual ball valve E13 are all close to one side of the liquid outlet pipe 15.

[0012] The storage tank A1 is arranged on a platform at a height of 2.7 m, the storage tank B7 is arranged below the platform at a height of 2.7 m, and the down pipe 6 is located at the lowest point of the liquid outlet pipe 15 .

[0013] During use, when the liquid level in storage tank A1 reaches 70% of the effective volume and the liquid needs to be transferred out, the on-site operator opens manual ball valve A2 and manual ball valve B4, closes manual ball valve E13, manual ball valve F16 and manual ball valve G17, and adjusts liquid transfer pump A3 to remote state. After the remote staff adjusts the opening of pneumatic ball valve A5, they start liquid transfer pump A3 to transfer the liquid, and the liquid is transferred out through the liquid outlet pipe 15; the material of each valve needs to be determined according to the properties of the on-site solution, and the pneumatic ball valve A5 is connected to the air source pipe.

[0014] When the liquid level in the storage tank A1 is about to reach the low point, the manual ball valve E13 is opened to a reasonable degree, and the liquid outlet pipe 15 is thoroughly purged through the compressed air pipe 14 to prevent the liquid from remaining in the liquid outlet pipe 15 and crystallizing due to low temperature.
