Two fixed tripods 2 are installed on the lower side of the tank body 1, the discharge port 3 is installed at the lower right position of the front side of the tank body 1, the feed port 4 is installed at the upper right position of the tank body 1, the pressure relief device 5 is installed at the middle position of the upper side of the tank body 1, and the platform 6 is installed on the upper side of the tank body 1;

[0024] Specifically, screw holes 201 are provided on both sides of the fixed tripod 2;

[0025] The platform 6 is installed on the upper side of the tank body 1, and ladders 601 of the same specifications are installed on both sides of the platform 6. A ladder 602 is installed on the right end of the platform 6 and the right side of the tank body 1;

[0026] The pressure relief device 5 includes a pressure relief pipe 501, a recovery pipe 502 and a storage bin 503. The left end of the recovery pipe 502 is mounted on the tank body 1, and the right end is mounted on the left side wall of the storage bin 503. The right end of the pressure relief pipe 501 is mounted on the tank body 1, and the left end is mounted on the right side wall of the pressure relief piston device 9.

[0027] An air pressure detector 7 and a one-way valve 8 are installed on the upper side of the storage bin 503;

[0028] The pressure relief piston device 9 is installed between the storage bin 503 and the pressure relief pipe 501. The pressure relief air pipe 902 connects the storage bin 503 and the pressure relief pipe 501. The surface of the pressure relief air pipe 902 is provided with a plurality of air holes 903.

[0029] A pressure relief chamber 901 is installed outside the pressure relief air pipe 902, a fixing plate 904 is installed inside the pressure relief air pipe 902, and a cavity cylinder 905 is installed on the right side of the fixing plate 904;

[0030] A spring 906 is installed inside the hollow cylinder 905, the spring 906 is connected to a baffle 907, and the right side of the baffle 907 is connected to a support 908;

[0031] A No. 1 piston pad 909 , a No. 2 piston pad 910 and a No. 3 piston pad 911 are installed on the right side of the support 908 .

[0032] The working principle of the utility model is:

[0033] When using a chemical storage tank with a pressure relief function, the tank body 1 and the transportation tool are installed and fixed by fixing the tripod 2. When the air pressure in the tank body 1 is too high, the gas squeezes the piston pad, so that the No. 1 piston pad 909, the No. 2 piston pad 910 and the No. 3 piston pad 911 are separated from the slot. When the gas is squeezed to the position of the air hole 903, the gas is discharged into the pressure relief bin 901 through the air hole 903, and then discharged into the storage bin 503 through the rear air hole 903. When the gas pressure in the tank body 1 becomes smaller, due to the action of the spring 906, the piston pad fits tightly into the slot. After unloading, the one-way valve 8 can be opened to allow the gas in the storage bin 503 to be withdrawn. The air pressure can be observed through the air pressure detector 7 to prevent the dangerous situation of explosion caused by excessive air pressure.
