Description

Technical Field

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

[0002] Monochloroacetone, as an important organic synthesis intermediate, is highly corrosive and toxic. The safety and durability of its storage equipment are crucial for chemical production, transportation, and storage. With the increasing stringent requirements for hazardous chemical storage regulations in the chemical industry, developing storage equipment with efficient corrosion resistance and stable shock resistance has become a key direction for technological development in the industry.

[0003] A search of Chinese patent document CN217262133U reveals a controllable acetone storage tank, comprising a storage tank, a cooling mechanism, a draining mechanism, a sealing gasket, a lifting assembly, and a first actuating assembly. The storage tank is internally divided into an upper and lower cooling chamber and a storage chamber by a partition with through holes. The storage chamber has an inlet and an outlet, both equipped with valves. The cooling mechanism, located in the cooling chamber, liquefies the volatile acetone and drains it into the storage chamber. The draining mechanism, located in the storage chamber, drains the acetone from the outlet. The draining mechanism includes a sealing gasket, a lifting assembly that moves the sealing gasket up and down, and a first actuating assembly mounted on the sealing gasket. This invention offers advantages such as quantitative acetone removal and the ability to utilize the evaporated acetone.

[0004] Although the aforementioned patent achieves the effect of quantitatively eliminating acetone, it does not take into account that the tank is easily subjected to high-frequency vibrations from surrounding large mechanical equipment or low-frequency large-amplitude vibrations such as strong winds during storage. This vibration directly affects the tank, which can easily cause problems such as cracking of the tank welds and loosening of the flanges. Therefore, a corrosion-resistant monochloroacetone storage tank is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a corrosion-resistant monochloroacetone storage tank, which aims to improve the problem that the existing technology is easily affected by high-frequency vibrations from surrounding large mechanical equipment or low-frequency large-amplitude vibrations such as strong winds during the storage process, which causes the vibration to act directly on the tank body and easily leads to cracking of the tank body welds and loosening of flanges.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A corrosion-resistant monochloroacetone storage tank includes a barrel body, an inlet pipe fixedly connected to the upper surface of the barrel body, an outlet pipe fixedly connected to the upper surface of the barrel body, a protective component provided on the side wall of the barrel body, and a corrosion-resistant component provided inside the barrel body.

[0008] The protective assembly includes a protective sleeve, with the side wall of the barrel slidably connected inside the protective sleeve. A skirt is fixedly connected to the side wall of the protective sleeve. A placement seat is slidably connected inside the protective sleeve. A damper is fixedly connected inside the protective sleeve, with its upper surface fixedly connected to the bottom of the placement seat. A fixing sleeve is fixedly connected inside the protective sleeve. A sliding block is slidably connected inside the fixing sleeve. A connecting plate one and a connecting plate two are rotatably connected to the side wall of the sliding block. A spring is fixedly connected inside the fixing sleeve, with one end of the spring fixedly connected to the side wall of the sliding block.

[0009] As a further description of the above technical solution:

[0010] The anti-corrosion component includes a protective layer disposed inside the barrel body, a bearing layer disposed on the side wall of the protective layer, a contact layer disposed on the side wall of the bearing layer, and a reinforcing ring fixedly connected to the side wall of the barrel body.

[0011] As a further description of the above technical solution:

[0012] The bottom of the barrel fits inside the placement seat, which is used to support the barrel.

[0013] As a further description of the above technical solution:

[0014] One end of the connecting plate is rotatably connected to the lower surface of the placement seat, and one end of the connecting plate is rotatably connected to the inside of the protective sleeve. The connecting plate and the connecting plate cooperate to push the sliding block to slide.

[0015] As a further description of the above technical solution:

[0016] The protective layer is made of epoxy zinc-rich primer and is used to provide cathodic protection to prevent the penetration of corrosive media.

[0017] As a further description of the above technical solution:

[0018] The supporting layer is made of carbon fiber and vinyl ester resin, which is used to resist both media corrosion and external atmospheric corrosion, and to prevent the metal base layer from rusting.

[0019] As a further description of the above technical solution:

[0020] The contact layer is made of perfluoroplastic to reduce localized corrosion caused by retention and deposit adhesion.

[0021] As a further description of the above technical solution:

[0022] The reinforcing rings are arranged vertically and evenly on the surface of the barrel to disperse circumferential stress and prevent the barrel from bulging.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the damper is compressed or stretched by the force applied to the placement seat, thereby reducing the transmission of vibration. At the same time, the movement of the placement seat causes the connecting plate to move, pushing the sliding block to slide within the fixed sleeve. When the sliding block slides, it compresses or stretches the spring, relying on elastic deformation to absorb vibration energy, and releases energy when the vibration weakens, so that the placement seat and the tank body can be restored to stability, thereby enhancing the stability of the storage tank on the ground. This solves the problem that some anti-corrosion monochloroacetone storage tanks cannot buffer vibration energy when subjected to high-frequency vibration from surrounding large mechanical equipment or low-frequency large-amplitude vibration from strong winds, causing the vibration to act directly on the tank body, which can easily lead to cracking of the tank body welds and loosening of flanges, thus reducing the stability of the storage tank on the ground. The above structure improves the protection effect on the tank body.

[0025] 2. In this utility model, the contact layer directly contacts monochloroacetone, preventing its corrosion and reducing the retention of the medium and the adhesion of deposits on the inner wall of the barrel. The bearing layer is located outside the contact layer, resisting the corrosion of monochloroacetone and also resisting corrosive substances in the external atmospheric environment, protecting the metal base from rust. The protective layer is used to block the penetration of external corrosive media, further extending the service life of the barrel. In addition, the reinforcing ring on the side wall of the barrel can effectively disperse the circumferential stress on the barrel when storing materials, preventing the barrel from bulging and deforming due to internal pressure, enhancing the structural strength of the barrel, and avoiding damage to the anti-corrosion layer due to structural deformation.

[0032] 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.

[0033] Example 1: Refer to Figures 1-3 A corrosion-resistant monochloroacetone storage tank includes a tank body 1. A feed pipe 2 is fixedly connected to the upper surface of the tank body 1. The feed pipe 2 is used to connect to an external conveying pipeline to convey monochloroacetone into the tank body 1. A discharge pipe 3 is fixedly connected to the upper surface of the tank body 1. The discharge pipe 3 is used to output the monochloroacetone stored in the tank body 1 to other equipment or containers to meet the material handling requirements. Protective components are provided on the side wall of the tank body 1, and corrosion-resistant components are provided inside the tank body 1.

[0034] The protective components include a protective sleeve 4, which wraps around the side wall of the tank 1, providing an external protective barrier to isolate the tank 1 from the influence of the external environment and enhance its safety. The side wall of the tank 1 is slidably connected inside the protective sleeve 4. A skirt 5 is fixedly connected to the side wall of the protective sleeve 4, which stably supports the protective sleeve 4 on the ground, enhancing the overall stability of the storage tank's connection to the ground and ensuring the stability of the storage tank during placement. A placement seat 6 is slidably connected inside the protective sleeve 4, supporting the tank 1 and distributing the weight of the tank 1 and its internal materials. A damper 7 is fixedly connected inside the protective sleeve 4. The damper 7 is a viscous damper, which converts vibration energy into heat energy through the shearing motion of the internal silicone oil. The upper surface of the damper 7 is fixedly connected to the placement seat 6. At the bottom, when the placement seat 6 is subjected to force, it drives the damper 7 to compress or stretch, thereby reducing the vibration transmission. The protective sleeve 4 is fixedly connected to the fixed sleeve 8, and the fixed sleeve 8 is slidably connected to the sliding block 9. The side wall of the sliding block 9 is rotatably connected to the connecting plate 10 and the connecting plate 21. The sliding block 9 slides in the fixed sleeve 8, which can convert and transmit the force transmitted by the placement seat 6. The fixed sleeve 8 is fixedly connected to the spring 12, and one end of the spring 12 is fixedly connected to the side wall of the sliding block 9. The spring 12 is used to absorb and release energy through elastic deformation. The bottom of the barrel 1 is attached to the inside of the placement seat 6. One end of the connecting plate 10 is rotatably connected to the lower surface of the placement seat 6, and one end of the connecting plate 21 is rotatably connected to the inside of the protective sleeve 4. The connecting plate 10 and the connecting plate 21 cooperate to push the sliding block 9 to slide.

[0035] Example 2: Refer to Figure 2 and Figure 4The anti-corrosion component includes a protective layer 13, which is disposed inside the barrel body 1. The protective layer 13 forms the first line of defense against corrosion inside the barrel body 1. By providing cathodic protection, it prevents corrosive media from penetrating into the metal substrate of the barrel body 1, thereby delaying the corrosion of the metal and extending the service life of the barrel body 1. A load-bearing layer 14 is provided on the side wall of the protective layer 13. The load-bearing layer 14 is made of carbon fiber and vinyl ester resin, which is used to resist both media corrosion and external atmospheric corrosion, preventing the metal substrate from rusting. The load-bearing layer 14 provides structural strength support for the barrel body 1, enabling the barrel body 1 to maintain a stable shape and structure when subjected to internal material pressure and external environmental forces. The design enhances the mechanical and corrosion resistance of the barrel 1. The sidewall of the bearing layer 14 is provided with a contact layer 15, which is made of perfluoroplastic and is used to directly contact monochloroacetone. Utilizing its chemical inertness and low surface energy, it reduces localized corrosion caused by retention and deposit adhesion, thereby protecting the inner wall of the barrel 1 and reducing the risk of material corrosion to the barrel 1. The sidewall of the barrel 1 is fixedly connected with reinforcing rings 16, which are arranged vertically and evenly on the surface of the barrel 1. They are used to disperse the circumferential stress on the barrel 1 when storing materials, preventing the barrel from bulging and deforming due to excessive internal pressure, thus enhancing the structural strength and stability of the barrel 1.

[0036] Working principle: When using this equipment for storage, monochloroacetone is delivered to the tank 1 through the feed pipe 2 for storage. When monochloroacetone is needed, the material is extracted from the tank 1 through the discharge pipe 3 via an external device. When the storage tank is subjected to external vibrations such as mechanical vibration or earthquakes, the tank 1 transmits the vibration to the placement seat 6. After the placement seat 6 is subjected to force, it will drive the damper 7 to compress or stretch. The damper 7 converts the vibration energy into heat energy and other forms of energy through its internal structure, thereby weakening the transmission of vibration. At the same time, the movement of the placement seat 6 will drive the connecting plate 10 to move. The movement of the sliding block 9 within the fixed sleeve 8 causes the sliding block 9 to slide. As the sliding block 9 slides, it compresses or stretches the spring 12. The spring 12 absorbs vibration energy through its elastic deformation and releases energy when the vibration weakens, restoring stability to the placement seat 6 and the tank body 1. During this process, one end of the connecting plate 11 is rotatably connected to the inside of the protective sleeve 4, and the other end is connected to the sliding block 9. It provides support and assists in transmitting force, ensuring the smooth sliding of the sliding block 9. The skirt 5 is fixedly connected to the side wall of the protective sleeve 4, providing stable support for the entire protective assembly and enhancing the stability of the storage tank on the ground. The contact layer 15 uses... Made of perfluoroplastics, it comes into direct contact with monochloroacetone. Its chemical inertness and low surface energy prevent corrosion from monochloroacetone, while reducing the retention of the medium and the adhesion of deposits on the inner wall of the container 1, thus lowering the risk of localized corrosion. The bearing layer 14, made of carbon fiber and vinyl ester resin, is located outside the contact layer 15. It not only resists corrosion from monochloroacetone but also resists corrosive substances in the external atmosphere, such as acid and alkaline gases and salt spray, protecting the metal base layer from rust and providing structural strength to the entire container 1, ensuring its stability during material storage. The protective layer 13 uses a ring-shaped... The zinc-rich primer is applied as the outermost anti-corrosion structure. Through the cathodic protection principle, when a minor damage occurs on the metal surface of the barrel 1, the zinc layer will be preferentially corroded, thereby protecting the metal of the barrel 1 and preventing the penetration of external corrosive media, further extending the service life of the barrel 1. In addition, the reinforcing rings 16 on the side wall of the barrel 1 are arranged vertically and evenly. When the barrel 1 stores materials, it can effectively disperse the circumferential stress on the barrel 1, prevent the barrel 1 from bulging and deforming due to internal pressure, enhance the structural strength of the barrel 1, and indirectly protect the anti-corrosion components, avoiding damage to the anti-corrosion layer due to structural deformation.
