DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4A protective pressure vessel comprises a tank body 1; a plurality of support brackets 11 arranged at the lower end of the tank body 1; a feed port 12 and a discharge port 13 arranged through the tank body 1, respectively used for feeding and discharging materials; sealing valves arranged at the feed port 12 and the discharge port 13 to ensure the sealing effect at the feed port 12 and the discharge port 13, and a protective sleeve 3 is arranged on the outer side of the tank body 1 to improve the strength of the tank body 1. A pressure relief port 4 is opened on the side wall of the tank body 1, and a pressure relief component 5 is arranged in the pressure relief port 4, which is used to relieve pressure when the pressure of the tank body 1 exceeds the setting to avoid material leakage caused by damage to the tank body 1.

[0024] The pressure relief assembly 5 includes a sealing core 51 and a mounting flange 511 arranged on the outside of the sealing core 51 corresponding to the pressure relief port 4. The sealing core 51 is installed in the pressure relief port 4 through the mounting flange 511 to ensure the sealing effect and facilitate the replacement of the sealing core 51. An air column 53 is arranged in the sealing core 51, and the air column 53 is filled with compressed inert gas, such as nitrogen, helium, etc., to prevent the gas in the air column 53 from leaking into the tank body 1 and affecting the purity of the material in the tank body 1, thereby ensuring the stability of the material. A connecting port 52 is arranged on the inner side of the air column 53 through the sealing core 51, and a piston 531 is sealingly and slidably installed in the air column 53. A pressure relief channel 55 is arranged on the side wall of the air column 53 near the connecting port 52, and the pressure relief channel 55 extends to the outside of the sealing core 51 and is connected to a discharge port 551.

[0025] When the pressure in the tank body 1 increases, pressure is applied to the piston 531 through the connecting port 52, squeezing the piston 531 to move outward until the pressure reaches the set value, and the piston 531 moves outward to the pressure relief channel 55 to leak out, and the gas material or liquid in the tank body 1 is sent to the discharge port 551 through the pressure relief channel 55 to be discharged for pressure relief. When the pressure is relieved to below the specified pressure, the elastic force of the compressed gas drives the piston 531 to reset and block the pressure relief channel 55 to ensure the closure of the tank body 1, thereby ensuring the protective effect of the tank body 1. The other end of the discharge port 551 is connected to the exhaust gas treatment device or the liquid treatment device for treatment to avoid danger or environmental pollution caused by leaked materials.

[0026] Based on the above technical solution, when the tank body 1 is filled with materials such as liquefied gas, when the pressure in the tank body 1 increases, the pressure pushes the piston 531 to move until the pressure reaches a predetermined upper limit, and the piston 531 moves to expose the inlet of the pressure relief channel 55, and the gas material is released through the pressure relief channel 55 and sent out through the discharge port 551, thereby relieving the pressure of the tank body 1 to ensure the stability of the pressure of the tank body 1 and to ensure the stable state of the tank body 1.

[0027] In this technical solution, if Figure 4As shown, a pressure regulating plug 54 is provided in a sealing and sliding manner in the gas column 53, and an adjusting bolt 541 is rotatably connected to the side of the pressure regulating plug 54 away from the piston 531. The adjusting bolt 541 extends out of the sealing core 51 and is threadedly connected to the sealing core 51. By rotating the adjusting bolt 541, the volume between the pressure regulating plug 54 and the piston 531 is adjusted to compress or release the compressed gas, and the force on the piston 531 is adjusted to adjust the upper pressure limit of the pressure relief assembly 5.

[0028] In this technical solution, if Figure 1 and 2 As shown, the protective sleeve 3 includes two symmetrically arranged sub-sleeves 31, the sub-sleeves 31 are fitted with the side wall of the tank body 1, arc-shaped reinforcing ribs 311 are evenly arranged on the outside of the sub-sleeves 31, and a butt joint edge 32 is arranged on the adjacent side of the sub-sleeves 31, and a plurality of matching locking holes 321 are opened on the butt joint edge 32. The tank body 1 is supported on the outside of the tank body 1 by the sub-sleeves 31 to improve the strength of the tank body 1, and the strength of the sub-sleeves 31 is improved on the outside by the reinforcing ribs 311 to avoid deformation of the side wall of the tank body 1 caused by long-term high pressure.

[0029] In this technical solution, if Figure 1 and 2 As shown, the sub-sleeve 31 and the reinforcing rib 311 are made of heat-conducting material or heat-insulating material. When it is necessary to avoid the temperature rise of the tank body 1, when storing endogenous high-temperature materials, the aluminum sub-sleeve 31 and the reinforcing rib 311 can be used to ensure the strength of the protective sleeve 3 and improve the heat dissipation effect of the tank body 1. For materials that need to be insulated, the protective sleeve 3 made of heat-insulating material can be used to isolate the tank body 1 from the outside heat to ensure that the temperature of the tank body 1 is constant.

[0030] In this technical solution, if Figure 1 and 2 As shown, an inspection port 14 is provided on one side of the tank body 1, and a matching sealing cover 2 is provided in the inspection port 14, so as to facilitate the inspection of the tank body 1.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
