Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and in particular to a corrosion-resistant steel-lined PTFE storage tank. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, storage tanks are crucial equipment for storing various corrosive liquids or gases, and their performance and safety are of paramount importance. Traditional storage tanks are usually made of metal materials, but metals are prone to corrosion and leakage when in contact with corrosive substances for a long time. This not only affects the storage effect but may also threaten the environment and personnel safety. To solve this problem, people have begun to use corrosion-resistant storage tanks, among which corrosion-resistant steel-lined PTFE storage tanks are highly favored due to their excellent corrosion resistance and stability.

[0003] However, existing anti-corrosion steel-lined PTFE storage tanks still have some technical problems in their design and use. On the one hand, the sealing performance of the tanks is not ideal, especially after long-term use. Due to the wear or aging of the seals, liquid or gas leakage is likely to occur, which not only affects the storage effect but may also cause environmental pollution. On the other hand, the practicality and ease of use of the tanks need to be improved. For example, observing the internal condition of the tank usually requires opening the tank cover, which is not only cumbersome but may also introduce external pollutants. In addition, the maintenance and replacement of parts of the tanks are relatively complex, increasing the cost of use and the difficulty of maintenance.

[0004] Therefore, in order to address this problem, this utility model presents a corrosion-resistant steel-lined PTFE storage tank. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a corrosion-resistant steel-lined PTFE storage tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a corrosion-resistant steel-lined PTFE storage tank, comprising a fixed tank body, a tank cover connected to the top of the fixed tank body by threads, a cover plate fixedly connected to the top of the tank cover, sliding frames symmetrically fixedly connected to the top of the cover plate, a sealing plug frame slidably connected to the surface of the sliding frame, a vent hole matching the sealing plug frame opened on the top of the cover plate, a locking sleeve connected to the top of the sliding frame by threads, and a moisture-proof pad covering the surface of the fixed tank body, with Velcro backing tapes glued to both ends of the moisture-proof pad.

[0007] Preferably, a fixing spring is fixedly connected to the bottom of the sealing plug holder, and the fixing spring is movably connected to the cover plate. The fixing spring is used to pop out the sealing plug holder for use.

[0008] Preferably, the top of the cover plate is rotatably connected to a pull handle via a pivot, and the side of the pull handle is textured.

[0009] Preferably, a sealing ring is provided on the top of the cover plate, and the sealing ring is provided on the side of the vent hole.

[0010] Preferably, four bulletproof glass panes are evenly embedded in the cover plate, and the bulletproof glass panes are used to observe the internal storage conditions.

[0011] Preferably, the moisture-proof mat is provided with a first hook and loop fastener front strip and a second hook and loop fastener front strip at both ends, and the first hook and loop fastener front strip and the second hook and loop fastener front strip are respectively bonded to the reverse hook and loop fastener.

[0012] Compared with the prior art, this utility model provides a corrosion-resistant steel-lined PTFE storage tank, which has the following beneficial effects:

[0013] 1. This corrosion-resistant PTFE-lined steel storage tank significantly improves its sealing performance through the use of a threaded tank cover and a fixed spring-driven sealing plug design. The threaded connection between the tank cover and the fixed tank body ensures a tight fit, effectively preventing liquid or gas leakage. At the same time, the fixed spring keeps the sealing plug above the vent hole at all times. When venting is not required, the sealing plug can automatically close the vent hole, further enhancing the tank's sealing performance. In addition, the design of the moisture-proof pad and Velcro effectively prevents external moisture from corroding the contents of the tank, improving the tank's corrosion resistance.

[0014] 2. This corrosion-resistant steel-lined PTFE storage tank features a handle and sliding frame design that makes operating the tank lid and sealing plug easier and reduces operational difficulty. In addition, the use of Velcro makes it convenient to remove and replace the moisture-proof pad, improving the tank's maintainability. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figures 1-3A corrosion-resistant steel-lined PTFE storage tank is first constructed by a fixed tank body 1, made of corrosion-resistant steel and lined with PTFE for superior corrosion resistance. A threaded interface is designed at the top of the fixed tank body 1 for connecting a tank cover 2. The tank cover 2 is tightly fixed to the fixed tank body 1 by the threads, ensuring the tank's airtightness. A cover plate 3 is fixedly connected to the top of the tank cover 2, supporting and protecting the structure above. Two sliding brackets 4 are symmetrically fixedly connected to the top of the cover plate 3, with a sealing plug bracket 5 slidably connected to each bracket. The sealing plug bracket 5 can move along the sliding brackets 4 to open or close the vent. Vent holes matching the sealing plug brackets 5 are provided at the top of the cover plate 3 to release internal pressure or perform other operations when needed. A thread is designed at the top of the sliding brackets 4. An interface is provided for connecting the locking sleeve 9, which can be rotated and secured to the sliding frame 4 to fix the position of the sealing plug frame 5. In addition, a moisture-proof pad 10 is covered on the surface of the fixed tank body 1. The two ends of the moisture-proof pad 10 are respectively glued to the reverse side of the Velcro strap 11 to firmly fix the moisture-proof pad 10 to the tank body and facilitate the staff to perform internal sealing and anti-corrosion treatment. Through this design, the storage tank has excellent corrosion resistance and sealing performance, which can effectively prevent excessive contact between the internal materials and the external environment, thereby affecting the storage effect. At the same time, the design of the sliding frame 4 and the sealing plug frame 5 allows the vent to be opened or closed flexibly, while the locking sleeve 9 ensures the stability of the sealing plug frame 5. The use of the moisture-proof pad 10 and the reverse side of the Velcro strap 11 further improves the moisture-proof performance and ease of maintenance of the storage tank.

[0022] At the bottom of the sealing plug holder 5, a fixing spring 6 is fixedly connected. The other end of the fixing spring 6 is movably connected to the cover plate 3. The design of the fixing spring 6 allows the sealing plug holder 5 to automatically pop out and cover the vent hole when no external force is applied, thereby maintaining the airtightness of the tank. When it is necessary to open the vent hole, simply push the sealing plug holder 5 gently to overcome the elasticity of the fixing spring 6 and remove the sealing plug holder 5 from the vent hole. The operation of the sealing plug holder 5 becomes more convenient. At the same time, the fixing spring 6 also ensures that the sealing plug holder 5 can automatically close the vent hole when no external force is applied, thereby improving the airtightness and safety of the storage tank.

[0023] At the top of the cover plate 3, a pull handle 7 is rotatably connected via a pivot. The pull handle 7 has textured edges to increase friction, making it easier for staff to grip and operate. The design of the pull handle 7 makes it easier for staff to open or close the can lid 2.

[0024] Among them, a sealing ring 8 is provided on the top of the cover plate 3. The sealing ring 8 is located on the side of the vent hole to enhance the sealing around the vent hole. The sealing ring 8 is made of elastic material and can fit tightly around the vent hole to prevent liquid or gas from leaking from the vent hole.

[0025] Among them, four bulletproof glass 301 are equidistantly embedded on the top of the cover plate 3. The bulletproof glass 301 has excellent transparency and impact resistance. Through the bulletproof glass 301, the staff can clearly observe the storage conditions inside the tank without opening the tank cover 2.

[0026] At both ends of the moisture-proof mat 10, there are Velcro front strips 1001 and 1002 respectively. Velcro front strips 1001 and 1002 are respectively bonded to the reverse side of the Velcro strip 11. This bonding method allows the moisture-proof mat 10 to be firmly fixed to the fixed tank 1 and facilitates disassembly and replacement by the staff. Through this design, the moisture-proof mat 10 is fixed more firmly and reliably, and it also facilitates the maintenance and replacement of the moisture-proof mat 10 by the staff. This helps to improve the moisture-proof performance and maintainability of the storage tank.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
