Technical Field

[0001] The utility model relates to the technical field of chemical storage tanks, in particular to a corrosion-resistant and wear-resistant storage tank. Background Art

[0002] Corrosion-resistant chemical storage tanks are containers specifically designed for storing various corrosive chemicals. These tanks are typically required to have a high degree of corrosion resistance and chemical stability to ensure they are not corroded during long-term storage, thereby ensuring the safety and service life of the tanks.

[0003] During the use of current storage tanks, the internal substances continuously corrode the inner wall of the tank. After long-term use, the tank is prone to structural damage. When the tank is damaged and causes chemical leakage, it is often difficult for staff to detect the leakage in the first time, resulting in pollution of the surrounding environment and difficulty in meeting usage needs. Utility Model Content

[0004] The purpose of the utility model is to provide a corrosion-resistant and wear-resistant storage tank. By arranging an isolation shell in the tank body, the storage tank can have a double isolation effect, and can send an alarm signal when the isolation shell leaks. At the same time, it can also prevent chemicals from leaking into the external environment after the isolation shell is damaged, making the storage tank safer when used.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a corrosion-resistant and wear-resistant storage tank, comprising a tank body, a partition fixed to the inner wall of the tank body, an isolation shell fixed to the top of the partition, a plurality of hydrophobic holes opened on the surface of the partition, a first pressure sensor fixed to the bottom of the inner wall of the tank body, a first liquid accumulation shell fixed to the top of the first pressure sensor, a bellows connected to the bottom of the first liquid accumulation shell, a first liquid discharge valve connected to the bottom of the tank body, a connecting pipe connected to the surface of the isolation shell, the surface of the connecting pipe passes through the tank body and is connected to the second liquid discharge valve, a protective box fixed to the surface of the tank body, a closed door hinged on the surface of the protective box, a second pressure sensor fixed to the bottom of the inner wall of the protective box, a second liquid accumulation shell fixed to the top of the second pressure sensor, the tank body composed of a multi-layer structure, a liquid adding valve fixed to the top of the tank body, a delivery pipe connected to the bottom of the liquid adding valve, the delivery pipe passing through the tank body, a buzzer and a warning light fixed to the top of the tank body, and a controller fixed to the top of the protective box.

[0006] As a preferred corrosion-resistant and wear-resistant storage tank of the present invention, the tank body includes an inner layer, a middle layer and an outer layer, the surface of the outer layer is provided with a wear-resistant coating, and the inner layer and the inner wall of the isolation shell are both provided with a corrosion-resistant coating.

[0007] As a preferred corrosion-resistant and wear-resistant storage tank of the present invention, the inner layer and the isolation shell are both made of PTFE, and the middle layer is made of 316L stainless steel.

[0008] As a preferred corrosion-resistant and wear-resistant storage tank of the present invention, the wear-resistant coating is a polyurethane coating, and the corrosion-resistant coating is an epoxy resin coating.

[0009] As a preferred corrosion-resistant and wear-resistant storage tank of the present invention, a mounting groove is opened above the inner wall of the tank body, an annular tube is fixed to the inner wall of the mounting groove, a plurality of drainage pipes are connected to the surface of the annular tube, a liquid adding pipe is connected to the surface of the annular tube, and both the drainage pipe and the liquid adding pipe pass through the tank body.

[0012] As a preferred corrosion-resistant and wear-resistant storage tank of the present invention, the outer layer is made of carbon steel.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] When the isolation shell in the present invention leaks, the chemical solution that seeps out of the surface of the isolation shell can fall onto the surface of the partition. At this time, the inner wall of the storage tank body can still block the chemical solution, thereby achieving a double protection effect to prevent the chemicals from directly leaking into the external environment. The chemical solution on the surface of the partition can flow into the first liquid accumulation shell through the hydrophobic holes. When the chemical solvent flows into the first liquid accumulation shell, the first pressure sensor detects an increase in the weight of the first liquid accumulation shell. At this time, the first pressure sensor will be able to transmit a signal to the controller, so that the controller controls the buzzer and the warning light, thereby reminding the surrounding staff of the chemical leakage through the buzzer and the warning light.

[0021] See also Figure 1-Figure 5 A corrosion-resistant and wear-resistant storage tank includes a storage tank body 1, a partition 2 is fixed to the inner wall of the storage tank body 1, an isolation shell 8 is fixed to the top of the partition 2, the top of the isolation shell 8 is fixedly connected to the top of the inner wall of the storage tank body 1, and a plurality of hydrophobic holes 7 are opened on the surface of the partition 2. A first pressure sensor 3 is fixed to the bottom of the inner wall of the storage tank body 1, a first liquid accumulation shell 4 is fixed to the top of the first pressure sensor 3, a bellows 5 is connected to the bottom of the first liquid accumulation shell 4, the bottom of the storage tank body 1 is connected to a first drain valve 6, the bottom of the bellows 5 is connected to the top of the first drain valve 6, the first liquid accumulation shell 4 is slidably connected to the inner wall of the storage tank body 1, the surface of the isolation shell 8 is connected to a connecting pipe 9, the surface of the connecting pipe 9 passes through the storage tank body 1 and is connected to the second drain valve 6. Liquid valve 10, a protection box 11 is fixed on the surface of the storage tank body 1, and a closed door 12 is hinged on the surface of the protection box 11. The second liquid discharge valve 10 is located inside the protection box 11, and a second pressure sensor 13 is fixed to the bottom of the inner wall of the protection box 11. A second liquid accumulation shell 14 is fixed on the top of the second pressure sensor 13. The storage tank body 1 is composed of a multi-layer structure. A liquid adding valve 15 is fixed on the top of the storage tank body 1. The bottom of the liquid adding valve 15 is connected to a delivery pipe, which runs through the storage tank body 1. A buzzer 16 and a warning light 17 are fixed on the top of the tank body 1. A controller 18 is fixed on the top of the protection box 11. The controller 18 is electrically connected to the buzzer 16, the warning light 17, the first pressure sensor 3 and the second pressure sensor 13;

[0022] When the storage tank body 1 is in use, chemical solvent can be added to the interior of the isolation shell 8 through the liquid filling valve 15. When the isolation shell 8 leaks, the chemical solution that seeps out of the surface of the isolation shell 8 can fall onto the surface of the partition 2. At this time, the inner wall of the storage tank body 1 can still block the chemical solution, thereby achieving a double protection effect to prevent the chemicals from directly leaking into the external environment. The chemical solution on the surface of the partition 2 can flow into the first liquid accumulation shell 4 through the hydrophobic hole 7. When the chemical solvent flows into the first liquid accumulation shell 4, the first pressure sensor 3 detects that the weight of the first liquid accumulation shell 4 increases. At this time, the first pressure sensor 3 will be able to transmit a signal to the controller 18, so that the controller 18 controls the buzzer 16 and the warning light 1 7, thereby using the buzzer 16 and the warning light 17 to remind the surrounding staff of chemical leakage, and opening the first drain valve 6 is used to discharge the chemical solution accumulated in the first liquid accumulation shell 4. When the second drain valve 10 is opened, the chemical solution in the isolation shell 8 will be discharged normally through the connecting pipe 9 and the second drain valve 10. When the second drain valve 10 leaks, the leaked chemicals will fall onto the surface of the second liquid accumulation shell 14, so that the second pressure sensor 13 can detect the pressure signal and transmit the signal to the controller 18, so that the controller 18 starts the buzzer 16 and the warning light 17 again, thereby achieving a double warning protection effect, thereby further improving the safety of the storage tank when in use.

[0023] Furthermore, the tank body 1 includes an inner layer 101, an intermediate layer 102 and an outer layer 103. The outer layer 103 is provided with a wear-resistant coating 104, and the inner layer 101 and the inner wall of the isolation shell 8 are provided with a corrosion-resistant coating 105.

[0024] The inner layer 101 is used to directly contact the corrosive medium and provide the most direct protection. The middle layer 102 can enhance the protection against chemical solutions. Even if there are minor defects in the inner layer 101, the middle layer 102 can continue to provide protection. The outer layer 103 is used to protect the external surface of the tank body 1 so that it is not subject to external wear during transportation and use. The wear-resistant coating 104 is used to further improve the wear resistance of the outer layer 103. The corrosion-resistant coating 105 can enhance the corrosion resistance of the inner layer 101 and the isolation shell 8.

[0025] Furthermore, the inner layer 101 and the isolation shell 8 are both made of PTFE, and the middle layer 102 is made of 316L stainless steel;

[0026] PTFE material has extremely high chemical stability and corrosion resistance, and is suitable for most corrosive media such as strong acids and strong alkalis. 316L stainless steel has good corrosion resistance and mechanical strength, and is suitable for most corrosive environments. As the intermediate layer 102, it can provide additional protection and support.

[0027] Furthermore, the wear-resistant coating 104 is a polyurethane coating, and the corrosion-resistant coating 105 is an epoxy resin coating;

[0028] Polyurethane coating has good wear resistance and is suitable for environments with severe wear. It also has good flexibility and can withstand certain physical stress. Epoxy resin coating has good corrosion resistance to most acids, alkalis, solvents and other chemicals. It is easy to spray and brush, dries quickly, and has a short construction period.

[0029] Furthermore, a mounting groove 19 is provided on the inner wall of the storage tank body 1, and an annular tube 20 is fixed to the inner wall of the mounting groove 19. The surface of the annular tube 20 is connected to multiple drainage pipes, and the surface of the annular tube 20 is connected to a liquid adding pipe. The drainage pipe and the liquid adding pipe both pass through the storage tank body 1.

[0030] The liquid adding pipe can be connected to the external water supply pipeline, so that the cleaning liquid can be transported to multiple drainage pipes through the annular pipe 20, so that the cleaning liquid can clean the inner wall of the storage tank body 1 and the outer surface of the isolation shell 8, thereby removing the chemical solution remaining on the inner wall of the storage tank body 1 and the outer surface of the isolation shell 8 after leakage.

[0031] Furthermore, a protective cover 21 is fixed on the surface of the storage tank body 1, and the protective cover 21 is made of HDPE material;

[0032] HDPE is highly resistant to most chemicals, including acids, alkalis, and many solvents. This makes it ideal for protecting the tank body from external corrosive substances. HDPE also has good wear resistance and can resist wear caused by friction and collision during transportation and use.

[0033] Furthermore, the hydrophobic holes 7 are distributed in a ring array on the surface of the separator 2;

[0034] By designing the hydrophobic holes 7 , leaked chemicals can more easily fall into the first liquid accumulation shell 4 through the hydrophobic holes 7 .

[0035] Furthermore, the outer layer 103 is made of carbon steel;

[0036] Carbon steel has high mechanical strength and cost-effectiveness, and is suitable for use as the outer layer 103 structural material. Its wear resistance can be further improved through surface treatment.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
