Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion coating storage technology, specifically an anti-corrosion coating storage device. Background Technology

[0002] Anti-corrosion coatings are special coatings used to protect substrates such as metals and concrete from corrosion. They form a dense protective layer to isolate water, oxygen, and chemical media, extending the service life of materials. Their core components include film-forming substances, anti-rust pigments, and additives. They possess properties such as acid and alkali resistance, salt spray resistance, and anti-aging. According to the protection principle, they can be divided into physical shielding type and electrochemical protection type. According to the application scenario, there are marine coatings, bridge coatings, pipeline coatings, etc. Modern anti-corrosion coatings also integrate nanotechnology and water-based processes to improve environmental protection and long-term effectiveness. They are widely used in marine engineering, petrochemical, infrastructure and other fields, and are key materials for reducing maintenance costs and ensuring structural safety.

[0003] Anti-corrosion coatings such as epoxy resin have a high viscosity and are in a highly viscous state before curing, which allows them to adhere well to the substrate. However, they are sensitive to light and oxygen. Exposure to light can easily trigger a polymerization reaction and cause deterioration. Therefore, they need to be stored in a dark and sealed environment to maintain their performance stability. They are commonly used in metal corrosion protection, floor coating, and other applications to provide long-lasting protection for projects.

[0004] When anti-corrosion coatings need to be removed for use during storage, their high viscosity can cause poor drainage, leading to air entering the storage tank and causing oxidation. The viscous coating also tends to stick to the inside of the tank, and the light-proof design makes it difficult to know the remaining coating level. Therefore, we propose an anti-corrosion coating storage device. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-corrosion coating storage device. By setting an isolation cylinder on the side of the tube body, the two are connected by a connecting pipe at the bottom. When the anti-corrosion coating is taken out, the valve on the connecting pipe is opened, causing the piston to move upward and smoothly draw the high-viscosity anti-corrosion coating into the isolation cylinder and discharge it. The whole process does not allow external air to enter the tank, so the anti-corrosion coating can be discharged smoothly and avoids oxidation caused by air entering. At the same time, it reduces the problem of coating residue on the inner wall of the tank and the isolation cylinder, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-corrosion coating storage device, comprising a tank and an isolation cylinder, wherein the tank is provided with a sealing plate that can slide up and down and whose outer ring is in contact with the inner wall surface of the tank; the isolation cylinder is fixed to the lower side surface of the tank, and the bottom of the isolation cylinder is connected to the bottom of the tank through a connecting pipe, a third valve is installed on the end of the connecting pipe near the isolation cylinder, and a discharge pipe communicating with the inside of the bottom side of the isolation cylinder is also connected to the discharge pipe, a second valve is installed on the discharge pipe, and an electric push rod is vertically installed on the top of the isolation cylinder, the protruding end of the electric push rod penetrates into the inside of the isolation cylinder, and a piston whose outer ring is in contact with the inner wall surface of the isolation cylinder and can slide up and down is fixed at the end of the electric push rod.

[0007] By adopting the above technical solution, when the anti-corrosion coating needs to be removed for use, the piston is first moved upward to draw the anti-corrosion coating into the isolation cylinder, and then the connecting pipe is closed and the piston is moved downward to discharge the anti-corrosion coating. This makes it easier to discharge the anti-corrosion coating with high viscosity and can prevent air from entering the tank and causing the coating to oxidize during storage.

[0008] Optionally, a vertical rod is vertically connected to the middle of the surface of the sealing plate, and the vertical rod passes through a through-hole opened on the top surface of the tank to the outside of the tank.

[0009] By adopting the above technical solution, the height of the sealing plate inside the tank can be determined by the height of the vertical rod, thereby determining the remaining amount of anti-corrosion coating.

[0010] Optionally, the diameter of the opening is larger than the diameter of the vertical rod, so that there is a gap between the vertical rod and the opening.

[0011] By adopting the above technical solution, air can enter and exit the tank through the gap when the sealing plate is raised and lowered, so that the height of the sealing plate is not affected by air pressure.

[0012] Optionally, the surface of the isolation cylinder is provided with a vertical observation window, and the surface of the observation window is uniformly provided with scale lines in the vertical direction.

[0013] By adopting the above technical solution, the movement of the electric actuator can be easily judged and controlled through the observation window and scale lines, thereby achieving the purpose of controlling the amount of anti-corrosion coating extracted.

[0014] Optionally, the bottom of the tank is connected to a filling pipe that communicates with the inside of the tank, and a first valve is installed on the filling pipe.

[0015] By adopting the above technical solution, the anti-corrosion coating to be stored is injected into the tank through the injection pipe.

[0016] Optionally, both the outer ring of the sealing plate and the outer ring of the piston are fitted with rubber rings, and the sealing plate and the piston are respectively attached to the inner wall surface of the tank and the inner wall surface of the isolation cylinder through the rubber rings.

[0017] By adopting the above technical solutions, the sealing effect between the sealing plate and the inner wall of the tank, and between the piston and the inner wall of the isolation cylinder, is improved.

[0018] Optionally, the bottom outer ring of the tank is vertically supported by legs, and multiple legs are provided.

[0019] By adopting the above technical solution, the tank body is stably supported by multiple legs.

[0020] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0021] 1. The technical solution of this application sets up an isolation cylinder on the side of the pipe body, and the two are connected by a connecting pipe at the bottom. The valve on the connecting pipe is opened only when the anti-corrosion coating is taken out, so that the piston moves up and can smoothly draw the high viscosity anti-corrosion coating into the isolation cylinder and discharge it. The whole process will not allow external air to enter the tank, so the anti-corrosion coating can be discharged smoothly and avoid oxidation caused by air entering. At the same time, the sealing plate and the piston scrape the inner wall of the tank body and the isolation cylinder respectively, thereby reducing the problem of coating residue on the inner wall of the tank body and the isolation cylinder.

[0022] 2. The technical solution of this application has a vertical rod placed in the middle of the sealing plate surface. After the vertical rod passes through the opening to the top of the tank, the height of the sealing plate inside the tank can be determined by the height of the vertical rod, and thus the remaining amount of anti-corrosion coating can be determined.

[0023] 3. The technical solution of this application provides an observation window and scale lines on the surface of the isolation cylinder, which allows observation of the amount of anti-corrosion coating inside the isolation cylinder. This enables precise control of the electric actuator's stroke and thus the amount of anti-corrosion coating extracted each time. Attached Figure Description

[0028] Please see Figure 1-2 This utility model provides a technical solution: an anti-corrosion coating storage device, including a tank 1 and an isolation cylinder 2. The bottom outer ring of the tank 1 is vertically supported by legs 11. Multiple legs 11 are provided, and each leg 11 is at the same height, so that the tank 1 is supported at a certain height on the ground.

[0029] Inside the tank 1, there is a sliding sealing plate 3 that can slide up and down and whose outer ring is in contact with the inner wall surface of the tank 1. A rubber ring 4 is fixed on the outer ring of the sealing plate 3. The sealing plate 3 is in contact with the inner wall surface of the tank 1 through the rubber ring 4. The bottom of the tank 1 is connected to an injection pipe 12 that communicates with the inside of the tank 1. A first valve 121 is installed on the injection pipe 12. When it is necessary to store the anti-corrosion coating inside the tank 1, the anti-corrosion coating delivery pipe is connected to the injection pipe 12 and the valve is opened. The anti-corrosion coating is injected into the inside of the tank 1 through the injection pipe 12 using pressure, and the sealing plate 3 is pushed upward. The inside of the tank 1 will not enter the air or be exposed to light, so as to achieve the purpose of light-proof and sealed storage.

[0030] The aforementioned isolation cylinder 2 is fixed to the lower side surface of the tank body 1. The bottom side of the isolation cylinder 2 is connected to a discharge pipe 22 that communicates with its interior, and a second valve 221 is installed on the discharge pipe 22 to control the opening and closing state of the discharge pipe 22. The bottom of the isolation cylinder 2 is connected to the bottom of the tank body 1 through a connecting pipe 23. A third valve 231 is installed on the end of the connecting pipe 23 near the isolation cylinder 2. An electric push rod 21 is vertically installed on the top of the isolation cylinder 2. The protruding end of the electric push rod 21 penetrates into the interior of the isolation cylinder 2, and a piston 211 is fixed to the end of the electric push rod 21. A rubber ring 4 is fixed to the outer ring of the piston 211. The piston 211 is in contact with the inner wall surface of the isolation cylinder 2 through the rubber ring 4, and the piston 211 is designed to slide up and down.

[0031] When it is necessary to remove the anti-corrosion coating, first control the third valve 231 to be in the open state, then the electric actuator 21 drives the piston 211 to move upward. The anti-corrosion coating inside the tank 1 can be drawn into the interior of the isolation cylinder 2 through the connecting pipe 23 at the bottom using negative pressure. Then, close the third valve 231 and open the second valve 221, so that the electric actuator 21 drives the piston 211 to lower the height. The anti-corrosion coating that has entered the isolation cylinder 2 can be squeezed out from the discharge pipe 22 and collected by the container below the discharge pipe 22. Then, close the second valve 221. In the above way, during the entire process of anti-corrosion coating injection and removal, air will not enter the tank 1 and cause the anti-corrosion coating to be oxidized. In addition, the movement of the sealing plate 3 and the piston 211 will scrape the inner wall of the tank 1 and the isolation cylinder 2, avoiding the presence of anti-corrosion coating residue on the inner wall surface of the tank 1 or the isolation cylinder, and the removal of the anti-corrosion coating is also smoother.

[0032] To achieve quantitative extraction, a vertical observation window 24 is provided on the surface of the isolation cylinder 2. The surface of the observation window 24 is uniformly provided with scale lines 241 in the vertical direction. The amount of anti-corrosion coating inside the isolation cylinder 2 can be observed through the scale lines 241, which is used to precisely control the movement stroke of the electric push rod 21 and control the amount of anti-corrosion coating extracted each time.

[0033] Since the anti-corrosion coating is stored in a light-proof environment, the remaining amount of anti-corrosion coating inside the tank 1 cannot be determined. In this application, a vertical rod 31 is vertically connected to the middle position of the surface of the sealing plate 3. The vertical rod 31 extends through the opening 13 on the top surface of the tank 1 to the outside of the tank 1. The height of the sealing plate 3 can be determined by the height of the vertical rod 31 extending out, and thus the remaining amount of anti-corrosion coating inside the tank 1 can be determined.

[0034] The diameter of the opening 13 is larger than the diameter of the vertical rod 31, so that there is a gap between the vertical rod 31 and the opening 13. When the sealing plate 3 is raised or lowered, air can enter and exit the tank 1 through the gap, so that the height of the sealing plate 3 is not resisted by air pressure.

[0035] In use, the control terminals of the first valve 121, the second valve 221, the third valve 231, and the electric actuator 21 are all connected to the industrial control computer, connecting the anti-corrosion coating delivery pipe to the main feed inlet. Opening the first valve 121 allows the anti-corrosion coating to be injected from the bottom into the tank 1. During injection, the sealing plate 3 is continuously pushed upwards to its highest point, preventing air from entering. Afterwards, closing the first valve 121 allows the anti-corrosion coating to be stored inside the tank 1 in a protected and light-proof manner. When it is necessary to remove the anti-corrosion coating, first control the third valve 231 to be open, then the electric actuator 21 drives the piston 211 upwards. Using negative pressure, the anti-corrosion coating inside tank 1 is drawn into the isolation cylinder 2 through the connecting pipe 23 at the bottom. To achieve quantitative extraction, the amount of anti-corrosion coating extracted can be determined by the scale line 241 on the surface of the observation window 24. Then, the third valve 231 is closed and the second valve 221 is opened, causing the electric actuator 21 to drive the piston 211 to descend. The anti-corrosion coating entering the isolation cylinder 2 can be squeezed out from the discharge pipe 22 and collected by the container below the discharge pipe 22. Then, the second valve 221 is also closed. During the entire process of injecting and removing the anti-corrosion coating, air will not enter the tank 1 and cause the anti-corrosion coating to oxidize. As the anti-corrosion coating inside tank 1 is gradually extracted, the height of the sealing plate 3 will also gradually decrease. The remaining amount of anti-corrosion coating inside tank 1 can be determined by the length of the connecting rod that is exposed.
