Description

Technical Field

[0001] This utility model relates to the technical field of PTFE-lined steel storage tanks, specifically a PTFE-lined steel storage tank with leak-proof function. Background Technology

[0002] Steel-lined PTFE storage tanks are composite containers with a steel outer shell and a polytetrafluoroethylene (PTFE) inner lining. They are specifically designed for storing highly corrosive media (such as acids, alkalis, and organic solvents). By combining the mechanical strength of metal with the corrosion resistance of PTFE, they achieve safe storage and transportation.

[0003] Patent document CN216071462U discloses a steel-lined PTFE storage tank with a sealed docking structure. It discloses that "the beneficial effects of this utility model are: when the steel-lined PTFE storage tank needs to be docked, the docking plate on the side of the left storage tank is inserted along the docking groove of the right storage tank. The left storage tank is rotated counterclockwise, so that the docking plate rotates counterclockwise along the docking groove. When the lower end of the convex rod passes through the circular hole and engages with the positioning groove, the left and right storage tanks are docked. Then, the left and right storage tanks are fixed together with bolts. The annular sealing plate and sealing gasket make the left and right storage tanks more sealed."

[0004] However, the aforementioned publicly available literature describes a steel-lined PTFE storage tank with a sealed docking structure, primarily addressing the issue of poor sealing performance in existing steel-lined PTFE storage tanks. However, this PTFE storage tank lacks pressure relief components, and if internal pressure accumulates, leakage is likely to occur.

[0005] In view of this, it is necessary to develop a steel-lined PTFE storage tank with leak-proof function, so as to avoid leakage of PTFE storage tank. Summary of the Invention

[0006] The purpose of this utility model is to provide a steel-lined PTFE storage tank with leak-proof function to solve the technical problem mentioned in the background art that the PTFE storage tank lacks pressure relief components and is prone to leakage if internal pressure accumulates.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel-lined PTFE storage tank with leak-proof function, comprising: a tank body, a top cover installed on the top of the tank body, a leak-proof venting assembly installed on the top of the top cover, the leak-proof venting assembly comprising a pressure relief port, an installation pipe, a solenoid valve and a pressure gauge, the pressure relief port being installed through the top of the top cover, the top of the pressure relief port being threadedly sealed with an installation pipe, the solenoid valve being installed at the top of the installation pipe, and the pressure gauge being installed through the top of the top cover, and the pressure gauge being electrically connected to the solenoid valve.

[0008] Preferably, a sealing ring is installed at the outer joint of the pressure relief port, and the sealing ring is located at the connection between the mounting pipe and the pressure relief port, and a pressure relief pipe is installed at the top of the solenoid valve.

[0009] Preferably, a feed inlet is installed through the center of the top of the top cover.

[0010] Preferably, a discharge valve is installed through the middle of the bottom of the storage tank body, and support legs are symmetrically installed at the bottom of the storage tank body.

[0011] Preferably, a protective assembly is installed on the outside of the storage tank body. The protective assembly includes a mounting shell, a protective airbag, and a protective outer wall. The mounting shell is installed on the outside of the storage tank body and surrounds the outside of the storage tank body in an annular shape. A protective airbag is installed on the inside of the mounting shell, and a protective outer wall is installed on the outside of the mounting shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The venting assembly in this utility model is used to release the pressure inside the storage tank. The vent is a threaded port that is connected to the mounting pipe, so that the solenoid valve is installed above the vent. At the same time, the pressure gauge is used to detect the internal pressure of the storage tank. When the internal pressure accumulates, the pressure gauge will detect and display the internal pressure, and at the same time control the solenoid valve to open. This allows the pressure accumulated inside the storage tank to pass through the vent, the mounting pipe, the solenoid valve, and finally be discharged through the vent pipe, thereby preventing the storage tank from leaking due to the accumulation of internal pressure.

[0014] 2. The protective component of this utility model is used to protect the outer side of the storage tank body. The protective airbag and the protective outer wall in the protective component are respectively installed on the inner and outer sides of the mounting shell. The protective airbag plays a buffering role. If there is an impact or bump, it will first come into contact with the protective outer wall, and then be buffered by the protective airbag, so as to avoid direct impact on the storage tank body and prevent the storage tank body from being dented or damaged.

[0023] Please see Figure 1 , Figure 2 and Figure 3 A steel-lined PTFE storage tank with leak-proof function;

[0024] The system includes: a storage tank body 1 and a leak-proof and venting assembly. A top cover 8 is installed on the top of the storage tank body 1. A leak-proof and venting assembly is installed on the top of the top cover 8. The leak-proof and venting assembly includes a pressure relief port 11, an installation pipe 13, a solenoid valve 14, and a pressure gauge 9. The pressure relief port 11 is installed through the top of the top cover 8. The installation pipe 13 is threaded and sealed on the top of the pressure relief port 11. The solenoid valve 14 is installed on the top of the installation pipe 13. The pressure gauge 9 is installed through the top of the top cover 8 and is electrically connected to the solenoid valve 14. A sealing ring 12 is installed at the outer mating point of the pressure relief port 11 and the sealing ring 12 is located at the connection between the installation pipe 13 and the pressure relief port 11. A pressure relief pipe 15 is installed on the top of the solenoid valve 14.

[0025] The storage tank body 1 is a PTFE storage tank used to store chemical gases and liquids, enabling the safe transport of these gases and liquids within the tank body 1. The top cover 8 is secured by bolts and other tight components and can be disassembled. The top cover 8 provides an installation position for the leak-proof venting assembly, which is used to release the pressure inside the storage tank body 1. The pressure relief port 11 is a threaded port connected to the installation pipe 13, allowing the solenoid valve 14 to be installed above the pressure relief port 11. Simultaneously, the pressure gauge 9 is used to detect the internal pressure of the storage tank body 1. When the internal pressure accumulates, the pressure gauge 9 detects and displays the internal pressure and simultaneously controls the solenoid valve 14 to open. This allows the pressure accumulated inside the storage tank body 1 to pass through the pressure relief port 11, the installation pipe 13, the solenoid valve 14, and finally be discharged through the pressure relief pipe 15, thus preventing leakage caused by the accumulation of internal pressure. Furthermore, the pressure relief port 11 and the installation pipe 13 are both made of copper, and sealing rings 12 are installed at the connection points to improve the sealing performance during connection.

[0026] Please see Figure 1 and Figure 4 A steel-lined PTFE storage tank with leak-proof function;

[0027] The tank includes a protective component 4, a feed inlet 10 through the center of the top of the top cover 8, a discharge valve 2 through the center of the bottom of the tank body 1, support legs 3 symmetrically installed at the bottom of the tank body 1, and a protective component 4 installed on the outside of the tank body 1. The protective component 4 includes a mounting shell 5, a protective airbag 6, and a protective outer wall 7. The mounting shell 5 is installed on the outside of the tank body 1 and surrounds the outside of the tank body 1 in a ring. The protective airbag 6 is installed on the inside of the mounting shell 5, and the protective outer wall 7 is installed on the outside of the mounting shell 5.

[0028] The feed inlet 10 provides space for materials to enter the interior of the storage tank body 1. When discharge is required, the discharge valve 2 is opened to allow the materials inside the storage tank body 1 to be discharged. The support leg 3 is used to support the bottom of the storage tank body 1. The protective component 4 is used to protect the outside of the storage tank body 1. The protective airbag 6 and the protective outer wall 7 in the protective component 4 are respectively installed on the inner and outer sides of the mounting shell 5. The protective airbag 6 plays a buffering role. If there is an impact or bump, it will first contact the protective outer wall 7, and then be buffered by the protective airbag 6 to avoid direct impact on the storage tank body 1, which would cause the storage tank body 1 to be dented or damaged.

[0029] Working principle: First, the storage tank body 1 is placed in the required position by the support leg 3. The material to be stored and transported is added into the storage tank body 1 through the feed port 10. When discharging, the discharge valve 2 is opened. During transportation, the outer side is protected by the protective component 4 to prevent the storage tank body 1 from being impacted or bumped, which could cause dents on the outer side. At the same time, a leak-proof venting component is installed. If the internal pressure is too high, the pressure can be released through the leak-proof venting component.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
