Description of the drawings:

FIG. 1 is a schematic view of the overall structure of the present invention;

in the figure, a storage tank 1, an overflow ring groove 2, an exhaust pipe 3, a liquid inlet pipe 4, a liquid outlet pipe 5, an overflow hole 6, a recovery tank 7, a piston plate 9, a cylinder 10, a shaft seal 11, a sealing ring 12, a self-flowing liquid pipe 13 and a recovery liquid pipe 14.

The specific implementation mode is as follows:

as shown in fig. 1, a safety overflow device for a chemical storage tank includes a vertically arranged storage tank 1, a liquid inlet pipe 4 and a liquid outlet pipe 5 are installed on the storage tank 1, an overflow ring groove 2 is installed on an outer circumferential surface of the storage tank 1, an overflow hole 6 is horizontally formed on an outer wall of the storage tank 1, the overflow hole 6 is communicated with the overflow ring groove 2, a gravity flow pipe 13 is vertically and downwardly connected to the overflow ring groove 2, a first ball valve is installed on the gravity flow pipe 13, an overflow liquid recovery device is installed at a bottom end of the gravity flow pipe 13, and the overflow liquid recovery device is connected to the storage tank 1; the overflow liquid recovery device comprises a horizontally arranged recovery liquid pipe 14, the recovery liquid pipe 14 is connected with the bottom end of the self-flowing liquid pipe 13, one end of the recovery liquid pipe 14 is connected with the storage tank 1, the other end of the recovery liquid pipe 14 is communicated with a recovery tank 7, a first ball valve and a second ball valve are mounted on the recovery liquid pipe 14, the first ball valve and the second ball valve are respectively arranged at two sides of the self-flowing liquid pipe 13, a piston plate 9 is vertically arranged in the recovery tank 7, the outer edge of the piston plate 9 is in sliding connection with the inner wall of the recovery tank 7, the piston plate 9 is connected with a piston rod of an air cylinder 10, the air cylinder 10 is fixedly mounted on a rack, a sliding through hole is horizontally formed in the recovery tank 7, and the piston rod of the air cylinder 10 is in sliding connection with the sliding through hole; a shaft seal 11 is arranged at the joint of the piston rod of the cylinder 10 and the sliding through hole; the overflow ring groove 2 is obliquely arranged, and the included angle between the overflow ring groove 2 and the horizontal direction is 10-20 degrees; the connection position of the gravity flow pipe 13 and the overflow ring groove 2 is positioned at the lowest end of the overflow ring groove 2; a sealing ring 12 is arranged on the outer edge of the piston plate 9; an exhaust pipe 3 is installed at the top end of the storage tank 1, and a safety air valve is installed on the exhaust pipe 3.
