Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-corrosion storage tank technology, specifically an anti-corrosion storage tank. Background Technology
[0002] Storage tanks are indispensable equipment in industrial production and logistics storage, and are widely used in many fields such as chemical, petroleum, pharmaceutical, and food. They are mainly used to store various liquid, gas, or solid materials. In many application scenarios, the materials stored in storage tanks are often corrosive, such as acid and alkali solutions in the chemical industry and sulfur-containing crude oil in the petroleum industry. These corrosive materials will continuously erode the inner wall of the storage tank, causing the tank wall to thin and leak. This will not only cause material loss, but may also lead to serious consequences such as environmental pollution and safety accidents.
[0003] An investigation revealed that a utility model patent (publication number: CN220097336U) discloses a negative pressure-resistant corrosion-resistant storage tank, comprising a tank body, an outer ring fitted with a protective layer, and several steel wire rings fitted between the outer ring and the protective layer. The combined use of the tank body, protective layer, and steel wire rings not only provides corrosion resistance to the tank body itself but also offers dual stable pressure resistance, effectively improving the tank's resistance to negative pressure. This prevents bulging, collapse, and detachment of the tank body due to negative pressure during prolonged use. Furthermore, the combined use of the tank body, support frame, connecting groove, pressure measuring pipe, valve, and base provides internal support for the tank body and allows users to monitor and release negative pressure during corrosion-resistant storage, preventing direct contact between the tank body and the ground, thus effectively improving the tank's performance and safety.
[0004] Although the aforementioned patent achieves corrosion protection on the outer wall of the tank, the interior of the tank is more prone to corrosion due to contact with corrosive materials. Furthermore, the friction and erosion of the materials inside the tank can cause traditional anti-corrosion coatings to peel off and crack during long-term use due to factors such as material erosion and temperature changes. The anti-corrosion effect is not durable and requires regular maintenance and recoating, which increases the cost of use and maintenance workload.
[0005] Therefore, this utility model provides a corrosion-resistant storage tank to solve the above problems. Utility Model Content
[0006] This utility model provides a corrosion-resistant storage tank, which aims to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a corrosion-resistant storage tank, comprising a corrosion-resistant storage tank, wherein the corrosion-resistant storage tank is sequentially connected from the inside to the outside with a corrosion-resistant inner lining, a honeycomb buffer layer, a storage tank body and a corrosion-resistant coating, a protective box is connected to one side of the corrosion-resistant storage tank and a door is hinged to the other end of the protective box, and a controller and a sensor group are connected inside the protective box. The support ring, support rib, and anti-slip protrusion are all connected to the inner wall of the corrosion-resistant storage tank.
[0008] As a preferred technical solution of this application, the anti-corrosion lining is made of polytetrafluoroethylene with a thickness of 5-10mm. An adhesive layer is provided between the anti-corrosion lining and the honeycomb buffer layer, as well as between the honeycomb buffer layer and the tank body, and the adhesive layer is made of epoxy adhesive.
[0009] As a preferred technical solution of this application, the anti-corrosion coating includes a primer layer, an intermediate paint layer and a topcoat layer from the inside out. The primer layer is an epoxy zinc-rich primer, the intermediate paint layer is an epoxy micaceous iron oxide intermediate paint, and the topcoat layer is an acrylic polyurethane topcoat.
[0010] As a preferred technical solution of this application, the top of the corrosion-resistant storage tank has an integrally formed manhole, and the top of the manhole is hinged with a sealing cover, and the bottom of the corrosion-resistant storage tank is fixedly connected with a support leg.
[0011] As a preferred technical solution of this application, the support ring has a ring structure and the support rings are arranged in an array along the axial direction of the anti-corrosion storage tank. The support ring is attached to the inner wall of the anti-corrosion lining. The support ring and the support rib are fixedly connected. The support rib is long and strip-shaped. The support rib and the anti-slip protrusion are distributed around the circumference of the inner wall of the anti-corrosion lining.
[0012] As a preferred technical solution of this application, the sensor group includes a corrosion sensor, a pressure sensor, and a temperature sensor, and the corrosion sensor, pressure sensor, and temperature sensor are electrically connected to the controller.
[0013] The beneficial effects of this application are as follows: This invention utilizes a polytetrafluoroethylene (PTFE) anti-corrosion lining layer on the inner wall of the storage tank, combined with an adhesive layer for a tight fit. PTFE has excellent chemical corrosion resistance and high and low temperature resistance, effectively isolating corrosive materials from direct contact with the storage tank body, thus fundamentally slowing down the corrosion rate of the storage tank body.
[0014] This utility model effectively supports the anti-corrosion liner through the cooperation of the support ring and the support rib, preventing it from deforming or falling off under the pressure of the material, thus improving the service life of the anti-corrosion liner. At the same time, anti-slip protrusions are set on the surface of the anti-corrosion liner to enhance the friction between the material and the anti-corrosion liner, prevent the material from shaking violently inside the storage tank, and reduce the wear of the material on the anti-corrosion liner.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figure 1-4 As shown, this utility model provides a corrosion-resistant storage tank, including a corrosion-resistant storage tank 1. From the inside to the outside, the corrosion-resistant storage tank 1 is sequentially connected with a corrosion-resistant inner lining layer 11, a honeycomb buffer layer 12, a storage tank body 13, and a corrosion-resistant coating 14. A protective box 2 is connected to one side of the corrosion-resistant storage tank 1, and a door 21 is hinged to the other end of the protective box 2. A controller 22 and a sensor group 23 are connected inside the protective box 2. Support rings 5, support ribs 6, and anti-slip protrusions 7 are all connected to the inner wall of the corrosion-resistant storage tank 1. The support rings 5 and support ribs 6 improve the safety protection of the inner wall of the corrosion-resistant storage tank 1, prevent deformation or detachment under material pressure, and improve the service life of the corrosion-resistant storage tank 1. At the same time, the anti-slip protrusions 7 increase the friction of the material and reduce the shaking of the material inside the corrosion-resistant storage tank 1, thereby reducing the wear of the material on the inside of the corrosion-resistant storage tank 1.
[0019] Furthermore, the anti-corrosion lining 11 is made of polytetrafluoroethylene (PTFE), which has excellent chemical corrosion resistance and high and low temperature resistance, effectively isolating corrosive materials from direct contact with the tank body 13. Its thickness is 5-10 mm. Adhesive layers are provided between the anti-corrosion lining 11 and the honeycomb buffer layer 12, as well as between the honeycomb buffer layer 12 and the tank body 13. The adhesive layers are made of epoxy adhesive, which improves the stability of the connection between the layers.
[0020] Furthermore, the anti-corrosion coating 14 comprises, from the inside out, a primer layer, an intermediate paint layer, and a topcoat layer. The primer layer uses an epoxy zinc-rich primer to enhance the adhesion and rust prevention of the anti-corrosion coating 14 to the outer wall of the storage tank body 13. The intermediate paint layer uses an epoxy micaceous iron oxide intermediate paint to enhance the shielding performance and mechanical strength of the anti-corrosion coating 14. The topcoat layer uses an acrylic polyurethane topcoat to provide excellent weather resistance and chemical corrosion resistance. Together, they improve the external anti-corrosion performance of the anti-corrosion storage tank 1.
[0021] Furthermore, the top of the anti-corrosion storage tank 1 is integrally formed with a manhole 3, and the top of the manhole 3 is hinged with a sealing cover 31. The bottom of the anti-corrosion storage tank 1 is fixedly connected with a support leg 4. The manhole 3 facilitates the inspection and maintenance of the interior of the anti-corrosion storage tank 1.
[0022] Furthermore, the support ring 5 has a ring structure and is arranged in an array along the axial direction of the anti-corrosion storage tank 1. The support ring 5 is attached to the inner wall of the anti-corrosion lining 11. The support ring 5 and the support rib 6 are fixedly connected. The support rib 6 is long and narrow. The support rib 6 and the anti-slip protrusion 7 are distributed around the circumference of the inner wall of the anti-corrosion lining 11. Through the reinforcement of the support ring 5 and the support rib 6, the service life of the anti-corrosion storage tank 1 is mainly improved and the pressure deformation of the anti-corrosion storage tank 1 is reduced. At the same time, the support ring 5 and the support rib 6 are both made of polypropylene and their surfaces are coated with polyvinylidene fluoride to avoid reducing the service life of the anti-corrosion lining 11 due to corrosion.
[0023] Furthermore, the sensor group 23 includes a corrosion sensor, a pressure sensor, and a temperature sensor, and the corrosion sensor, pressure sensor, and temperature sensor are electrically connected to the controller 22. The corrosion sensor is used to monitor the corrosion rate of the tank body 13 and the anti-corrosion lining 11, and the pressure sensor and temperature sensor are used to monitor the pressure and temperature inside the anti-corrosion tank 1, so as to realize remote monitoring in conjunction with the controller 22.
[0024] Working principle: During use, an appropriate amount of material is added into the interior of the anti-corrosion storage tank 1 through the feed inlet. Under the real-time monitoring of the sensor group 23, the safety of use inside the anti-corrosion storage tank 1 is ensured. During the material storage process, the anti-corrosion lining 11 isolates the material from direct contact with the tank body 13, preventing the tank body 13 from being corroded. The cooperation between the support ring 5 and the support rib 6 provides support for the anti-corrosion lining 11, preventing it from deforming and falling off. At the same time, the anti-slip protrusions 7 increase the sliding friction of the material, reduce the shaking of the material inside the anti-corrosion storage tank 1, thereby reducing the wear on the inner wall of the anti-corrosion lining 11.
[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
