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 an internal reinforcing structure. Background Technology

[0002] Steel-lined PTFE storage tanks are composite chemical containers that combine the strength of metal with the corrosion resistance of polytetrafluoroethylene (PTFE). They are widely used for storing highly corrosive media and can store almost all strong acids (such as aqua regia, nitric acid, and sulfuric acid), strong alkalis, and organic solvents. The applicable pH range is 1-14. The PTFE layer has strong barrier properties, preventing the penetration of small molecule gases (such as chlorine and hydrogen chloride).

[0003] Patent document CN216835359U discloses a steel-lined PTFE storage tank with an internal reinforcing structure. It states that "the beneficial effects of this utility model are: the reinforcing cylinder further strengthens the sturdiness of the steel-lined PTFE storage tank, thereby effectively protecting the internal PTFE lining body; the reinforcing sleeve, when the outer steel-lined storage tank is deformed by collision or compression, the deformed steel-lined storage tank compresses the reinforcing sleeve, and since the reinforcing sleeve is wavy, it can play a buffering role, thereby protecting the internal PTFE lining body; since the annular bottom plate is connected to the base by bolts, the reinforcing cylinder and reinforcing sleeve are easy to replace and maintain later."

[0004] However, the steel-lined PTFE storage tank with built-in reinforcement structure mentioned in the above-mentioned literature mainly considers the problem that existing PTFE storage tanks do not have a buffering effect and are prone to deformation due to compression. However, after the PTFE storage tank is compressed, the reinforcement sleeve only plays a buffering role and cannot prevent the outer side of the storage tank from being compressed and deformed.

[0005] In view of this, it is necessary to develop a steel-lined PTFE storage tank with an internally reinforced structure, which can prevent the PTFE storage tank from deforming under external pressure and improve the stability of the PTFE storage tank from the inside. Summary of the Invention

[0006] The purpose of this utility model is to provide a steel-lined PTFE storage tank with an internal reinforcing structure to solve the technical problem mentioned in the background art that, after being squeezed, the reinforcing sleeve of the PTFE storage tank only plays a buffering role and cannot prevent the outer side of the storage tank from being squeezed and deformed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel-lined PTFE storage tank with an internal reinforcing structure, comprising: a tank body, wherein a reinforcing component is installed inside the tank body, the reinforcing component being used to enhance the robustness of the tank body, the reinforcing component comprising a cross support frame, a first stabilizing plate, a second stabilizing plate, a third stabilizing plate, and a fourth stabilizing plate, wherein the first stabilizing plate, the second stabilizing plate, the third stabilizing plate, and the fourth stabilizing plate are respectively installed at one end of the cross support frame, and the first stabilizing plate, the second stabilizing plate, the third stabilizing plate, and the fourth stabilizing plate are fixed to the inner wall of the tank body.

[0008] Preferably, the inner wall of the storage tank body is lined with PTFE, and support legs are symmetrically installed at the bottom of the storage tank body.

[0009] Preferably, a drain pipe is installed through one side of the bottom of the storage tank body.

[0010] Preferably, a removable sealing cover is bolted to the top of the storage tank body, and a feed inlet is installed through the top of the removable sealing cover.

[0011] Preferably, the outer side of the storage tank body has a symmetrical protective outer ring, and mounting plates are symmetrically installed on the outer side of the protective outer ring.

[0012] Preferably, the mounting plate has a mounting groove on its outer side, and a lifting ring is installed inside the mounting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the first stabilizing plate, the second stabilizing plate, the third stabilizing plate and the fourth stabilizing plate in the reinforcing component are connected by a cross support frame. At the same time, the first stabilizing plate, the second stabilizing plate, the third stabilizing plate and the fourth stabilizing plate are fixed on the inner wall of the storage tank body, thereby supporting the interior of the storage tank body, thus making the storage tank body more stable and more resistant to pressure.

[0015] 2. In this utility model, the protective outer ring provides a position for the installation of the mounting plate, and at the same time, the protective outer ring is also used to protect the outside of the tank body. The mounting plate provides a position for the opening of the mounting groove. The inside of the mounting groove is used to install the lifting ring. Since the tank body is heavy, it needs to be lifted when moving. By installing the lifting ring on the outside of the tank body, the tank body can be easily lifted and moved, thus improving the lifting efficiency of the tank body. Attached Figure Description

[0024] Please see Figure 1 , Figure 2 and Figure 3 A steel-lined PTFE storage tank with an internal reinforced structure;

[0025] It includes: a storage tank body 1 and a reinforcing assembly 7. The reinforcing assembly 7 is installed inside the storage tank body 1. The reinforcing assembly 7 is used to strengthen the stability of the storage tank body 1. The reinforcing assembly 7 includes a cross support frame 8, a first stabilizing plate 9, a second stabilizing plate 10, a third stabilizing plate 11 and a fourth stabilizing plate 12. The first stabilizing plate 9, the second stabilizing plate 10, the third stabilizing plate 11 and the fourth stabilizing plate 12 are respectively installed at one end of the cross support frame 8, and the first stabilizing plate 9, the second stabilizing plate 10, the third stabilizing plate 11 and the fourth stabilizing plate 12 are fixed to the inner wall of the storage tank body 1.

[0026] The tank body 1 has good corrosion resistance. To ensure the robustness of the tank body 1, a reinforcing assembly 7 is installed inside. The first stabilizing plate 9, the second stabilizing plate 10, the third stabilizing plate 11, and the fourth stabilizing plate 12 in the reinforcing assembly 7 are connected by a cross support frame 8. At the same time, the first stabilizing plate 9, the second stabilizing plate 10, the third stabilizing plate 11, and the fourth stabilizing plate 12 are fixed to the inner wall of the tank body 1, thereby supporting the interior of the tank body 1. This makes the tank body 1 more stable and has a higher compressive strength. The outer side of the reinforcing assembly 7 is also equipped with a PTFE liner 6, thereby ensuring the corrosion resistance of the reinforcing assembly 7.

[0027] Please see Figure 1 and Figure 4 A steel-lined PTFE storage tank with an internal reinforced structure;

[0028] The tank body 1 includes a protective outer ring 13 and a lifting ring 16. A PTFE liner 6 is installed on the inner wall of the tank body 1. Support legs 2 are symmetrically installed at the bottom of the tank body 1. A drain pipe 3 is installed through one side of the bottom of the tank body 1. A disassembly sealing cover 4 is installed on the top of the tank body 1 by bolts. A feed inlet 5 is installed through the top of the disassembly sealing cover 4. A protective outer ring 13 is symmetrically installed on the outer side of the tank body 1. An installation plate 14 is symmetrically installed on the outer side of the protective outer ring 13. An installation groove 15 is opened on the outer side of the installation plate 14. A lifting ring 16 is installed inside the installation groove 15.

[0029] The PTFE liner 6 is used to improve the corrosion resistance of the tank body 1. The bottom of the tank body 1 is supported by the support legs 2. The liquid to be stored is added into the interior of the tank body 1 through the inlet 5 and discharged through the drain pipe 3. At the same time, a connecting flange is installed at one end of the inlet 5 and the drain pipe 3 to enable connection. The sealing cover 4 can be removed from the top of the tank body 1, making the tank body 1 easy to disassemble. The protective outer ring 13 provides a position for the installation of the mounting plate 14, and also protects the outside of the tank body 1. The mounting plate 14 provides a position for the opening of the mounting groove 15. The inside of the mounting groove 15 is used to install the lifting ring 16. Since the tank body 1 is heavy, it needs to be lifted when moving. The lifting ring 16 is installed on the outside of the tank body 1 to facilitate the lifting and movement of the tank body 1 and improve the lifting efficiency of the tank body 1.

[0030] Working principle: First, the PTFE storage tank is placed in the required position via support legs 2. Then, the pipe for transmitting liquid is connected to the top of the inlet 5, allowing the liquid to enter the interior of the tank body 1 for storage. Due to the PTFE lining 6 inside the tank body 1, the tank body 1 has good corrosion resistance. The liquid in the tank body 1 is discharged through the drain pipe 3. Both the inlet 5 and the drain pipe 3 have PTFE lining 6 on their inner walls. When the PTFE storage tank needs to be lifted and transported, the lifting hook can be directly connected to the lifting ring 16, and the lifting ring 16 is installed around the tank body 1 to ensure the stability of the tank body 1 during lifting.
