Description

Technical Field

[0001] This utility model relates to the field of medicine tank technology, specifically a multi-layer protective corrosion-resistant medicine tank. Background Technology

[0002] A chemical tank is a container specifically designed for storing, transporting, or temporarily transferring various liquid chemicals. A multi-layered, corrosion-resistant chemical tank is a multi-layered composite structure storage container designed for corrosive, volatile, or high-purity liquid chemicals. Existing technology involves directly placing the chemicals in a storage tank, exposing them to the air without any protective measures. This open storage environment accelerates the decrease in chemical concentration, increases the amount of chemicals used, and, in harsh environments, accelerates chemical expiration. Decreased chemical concentration or premature expiration directly affects the quality of PCB components, potentially leading to scrapping or rework. However, a PCB chemical storage tank (CN221586382U) uses a sealed space created by the tank body and movable covers and doors. Placing the chemicals within this sealed space prevents direct exposure to air, reducing the risk of concentration decreases and premature expiration due to environmental factors, thus mitigating potential quality risks.

[0003] While the aforementioned technologies can reduce the concentration reduction and premature expiration of the medicine due to environmental factors, they cannot protect the medicine inside the container. This can lead to the medicine seeping into the container, leaking through gaps, or coming into direct contact with people's skin and mucous membranes due to corrosion or damage to the container, causing burns and chemical dermatitis. If it evaporates into the air, it can also irritate the respiratory tract, causing coughing, difficulty breathing, and even damage to the respiratory mucosa. Utility Model Content

[0023] 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.

[0024] This utility model provides the following technical solution: a multi-layer protective corrosion-resistant chemical tank:

[0025] Example 1: To address the problem that existing medicine tanks cannot protect the medicine inside the tank, the following is disclosed: an inner tank 1, with a water pipe 2 penetrating one end of the top of the inner tank 1; an outer tank 3 is fitted over the outer surface of the inner tank 1, with the water pipe 2 also penetrating one end of the top of the outer tank 3; and buffer plates 4 are provided around the inside of the outer tank 3 (e.g., Figure 2 and Figure 5As shown), for cushioning, four buffer plates 4 are respectively provided with pads 5 on the side away from the outer box 3, and the pads 5 are respectively provided around the inner box 1 on the side away from the buffer plates 4. Buffer strips 19 are also provided around the inside of the outer box 3. A sealing sleeve 12 is slidably connected to the outer surface of the water pipe 2 (as shown). Figures 1-4 and Figure 6 As shown), the inner casing 1 consists of a sealing layer 9, a reinforcing layer 10, and a contact layer 11. The outer side of the contact layer 11 and the inner side of the reinforcing layer 10 are bonded together, and the outer side of the reinforcing layer 10 and the inner side of the sealing layer 9 are bonded together. The outer casing 3 consists of a support layer 6, an insulation layer 7, and a protective layer 8. The outer side of the support layer 6 and the inner side of the insulation layer 7 are bonded together, and the outer side of the insulation layer 7 and the inner side of the protective layer 8 are bonded together (as shown). Figure 5 As shown), all four buffer plates 4 are made of hot-dip galvanized material, and the four buffer strips 19 and pads 5 are made of rubber material.

[0026] The medicine to be stored can be added into the inner box 1 through water pipe 2. Then, the outer box 3 and the inner box 1 form a double-layer protection. When the medicine enters the inner box 1, it will come into contact with its internal contact layer 11 (e.g., ...). Figure 3 As shown), the contact layer 11 can be made of polytetrafluoroethylene (PTFE), thus preventing the contact layer 11 from reacting with the solution, avoiding solution deterioration or material leaching that could contaminate the solution. It also makes the surface of the contact layer 11 smooth, reducing solution residue and facilitating cleaning. Furthermore, PTFE has strong corrosion resistance, preventing the contact layer 11 from being corroded by the solution. The reinforcing layer 10 can be made of carbon fiber reinforced composite material (such as...). Figure 5 As shown), this not only improves the overall rigidity of the inner casing 1, resisting the bulging and deformation of the inner casing 1 caused by the pressure of the medicine, but also compensates for the insufficient strength of the contact layer 11, extending the service life of the inner casing 1. The sealing layer 9 can be made of butyl rubber, forming a leak-proof barrier. Even if the contact layer 11 or the reinforcing layer 10 develops minor cracks, the sealing layer 9 can prevent the medicine from leaking into the outer casing 3, thus enhancing the overall sealing performance of the inner casing 1 and reducing the evaporation of the medicine. The support layer 6 can be made of cold-rolled steel plate (such as...). Figure 2 and Figure 5 As shown), it can provide basic rigidity for the outer casing 3, supporting the weight of the inner casing 1 and the buffer plate 4. It can cooperate with the buffer plate 4 to distribute the pressure transmitted by the inner casing 1 and prevent the outer casing 3 from deforming. The insulation layer 7 can be made of closed-cell foamed polyurethane, which can isolate the influence of external temperature changes on the internal medicine, reduce heat exchange between the inner casing 1 and the outer casing 3, and maintain the stability of the medicine storage temperature. The protective layer 8 can be made of color-coated steel plate material (such as...). Figure 2 and Figure 5As shown, the buffer plate 4, made of hot-dip galvanized material, can resist external physical impact and environmental corrosion. It can also distribute the radial pressure of the inner box 1 and prevent excessive local stress on the inner box 1. The rubber pad 5 can flexibly contact the inner box 1 to avoid wear caused by hard friction between the buffer plate 4 and the inner box 1. It can also absorb vibration and reduce fatigue damage to the inner box 1 caused by vibration. The buffer strip 19 can fill the gap between the inner box 1 and the outer box 3 to further enhance the buffering effect.

[0027] Example 2: Unlike Example 1, the sealing component can seal the water pipe 2. It is disclosed that: the sealing sleeve 12 has a sealing component inside to seal the water pipe 2, and the top of the outer casing 3 has a limiting component to limit the sealing sleeve 12. The sealing component includes a sealing plug 13 (e.g., a sealing plug 13 at the bottom of the sealing sleeve 12) Figure 4 As shown), the sealing plug 13 is also slidably connected to the inside of the water pipe 2. A support ring 14 is provided at the upper middle end of the inside of the water pipe 2. A first sealing ring 15 is provided at the top of the support ring 14. A second sealing ring 16 is provided at one end of the sealing plug 13. The bottom of the second sealing ring 16 and the top of the first sealing ring 15 are in movable contact to seal the inside of the water pipe 2. The limiting component includes a limiting ring 17 (as shown) provided at the top of the outer casing 3. Figures 1-4 and Figure 6 As shown), both ends of the limiting ring 17 have storage grooves, and wedge-shaped blocks 18 are slidably connected inside each of the two storage grooves. Both ends of the sealing sleeve 12 have slots that fit the wedge-shaped blocks 18. A spring is provided between one end of each of the two wedge-shaped blocks 18 and the inside of the two storage grooves. One end of each of the two wedge-shaped blocks 18 is also provided with a pull rod (such as...) slidably connected inside the limiting ring 17. Figure 6 As shown in the figure, both pull rods have pull rings at the ends away from the wedge-shaped block 18 for pulling the pull rods.

[0028] When sealing the water pipe 2 is required, the sealing sleeve 12 can be aligned with the water pipe 2, and then the sealing sleeve 12 can be moved downwards to slide on the outer surface of the water pipe 2, thereby causing the sealing plug 13 to slide inside the water pipe 2. Subsequently, the sealing plug 13 will cause the second sealing ring 16 to contact the first sealing ring 15, and the two sealing rings will undergo elastic deformation due to compression (e.g., Figure 4 As shown), the sealing sleeve 12 fills the tiny gap between the sealing plug 13 and the support ring 14, thus achieving a sealing effect. When the sealing sleeve 12 descends, it also enters the limiting ring 17, where its bottom contacts the wedge-shaped locking block 18, pushing it to move within the receiving groove and compressing the spring. As the sealing sleeve 12 continues to descend, the groove and the wedge-shaped locking block 18 eventually reach the same horizontal level. Then, under the action of the spring, it drives the wedge-shaped locking block 18 into the groove, thereby limiting and fixing the sealing sleeve 12 (as shown). Figure 4 and Figure 6 As shown, when it is necessary to disassemble the sealing sleeve 12, the pull ring can be pulled to move the pull rod and the wedge-shaped block 18 away from the groove.
