Description

Technical Field

[0001] This utility model relates to a storage device for anti-corrosion primer, and more particularly to a storage device for anti-corrosion primer for ship plates. Background Technology

[0002] Anti-corrosion primer is a two-component coating with medium-molecular-weight epoxy resin, special resin, iron oxide red, zinc powder and other main components. It is made by mixing paint and amine curing agent and is suitable for anti-corrosion of bridges, ships, offshore facilities and industrial steel structures. It achieves excellent rust prevention performance and cathodic protection function through the dual protection of iron oxide red and zinc powder.

[0003] Due to the special properties of anti-corrosion primers, strict storage measures are required to prevent them from coming into contact with air and causing oxidation, which would reduce their anti-corrosion performance. Most existing storage devices for anti-corrosion primers for ship plates are open-top storage devices, which cannot be completely sealed during use, or leave a small amount of air inside the storage tank after sealing, which can cause the anti-corrosion primer to deteriorate. Utility Model Content

[0004] The purpose of this utility model is to provide a storage device for anti-corrosion primer for ship plates, which solves the problem that existing storage devices for anti-corrosion primer for ship plates mostly adopt open-top storage devices, which cannot be sealed during use, or leave a small amount of air in the storage tank after sealing, causing the anti-corrosion primer to deteriorate.

[0005] To solve the above problems, this utility model provides a storage device for anti-corrosion primer for ship plates, including a storage tank, an inlet pipe at the bottom of the storage tank with a one-way valve, an outlet pipe at the bottom of the storage tank with a shut-off valve, the storage tank being filled with inert gas, and a pressure gauge installed at the top of the storage tank.

[0006] The ship plate anti-corrosion primer storage device provided by this utility model also has the following technical features:

[0007] Furthermore, a gas cylinder is fixedly connected to the top of the storage tank, and a vent is provided between the gas cylinder and the storage tank.

[0008] Furthermore, an inflation valve is fixedly connected to the top of the gas tank, and a piston plate that slides up and down under the action of pressure difference is provided inside the tank. The piston plate seals and divides the tank into a gas chamber and a liquid chamber.

[0009] Furthermore, a guide rod is fixedly connected to the top of the piston plate, and a guide hole is provided on the top of the storage tank for the guide rod to slide out. The guide rod passes through the guide hole and extends into the gas tank.

[0010] Furthermore, the piston plate has a groove on its edge, and a sealing strip is provided in the groove. The sealing strip abuts against the groove and the inner wall of the storage tank.

[0011] Furthermore, both the storage tank and the gas tank are pressure-resistant containers.

[0012] The present invention has the following advantages: it uses inert gas to replace the air in the tank, and avoids contact with air after the anti-corrosion paint is filled in. At the same time, the gas pressure in the tank makes it easy to unload the anti-corrosion paint when it is taken out. After taking it out, there is no need to consider the sealing problem, which can effectively prevent the anti-corrosion paint from deteriorating and has a better storage effect.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0019] like Figures 1 to 4 In the embodiment of the ship plate anti-corrosion primer storage device of the present invention shown, the ship plate anti-corrosion primer storage device includes a storage tank 1, a feed pipe 2 at the bottom of the storage tank 1, a one-way valve 3 on the feed pipe 2, a discharge pipe 4 at the bottom of the storage tank 1, a shut-off valve 5 on the discharge pipe 4, the storage tank 1 is filled with inert gas, and a pressure gauge 6 is installed on the top of the storage tank 1.

[0020] Specifically, opening the shut-off valve 5 allows inert gas to be introduced through the inlet pipe 2, displacing the air in storage tank 1 through the outlet pipe 4. Closing the shut-off valve 5 allows the inert gas in storage tank 1 to reach a certain pressure (greater than atmospheric pressure), at which point the inflation stops. Anti-corrosion paint is then introduced into storage tank 1 through the inlet pipe 2. The anti-corrosion paint compresses the inert gas in storage tank 1, causing the gas pressure inside storage tank 1 to increase as the liquid level rises. Once a certain pressure is reached, the inflation stops. During use, opening the shut-off valve 1 allows the anti-corrosion paint to flow out under the pressure of the inert gas. For smoother unloading of the anti-corrosion paint compared to vacuum storage, the shut-off valve 5 can be closed after use without the need for resealing. This device uses inert gas filled into the storage tank 1 to replace the air inside the tank, preventing the anti-corrosion paint from contacting air after filling. At the same time, the gas pressure inside the storage tank 1 facilitates unloading of the anti-corrosion paint, and there is no need to consider sealing after use, which can effectively prevent the anti-corrosion paint from deteriorating and has a better storage effect. It should be noted that the shut-off valve 5 and the one-way valve 3 are existing technologies, and their specific structures will not be described in detail here.

[0021] In one embodiment of this application, preferably, a gas tank 7 is fixedly connected to the top of the storage tank 1, and a vent 8 is connected between the gas tank 7 and the storage tank 1, so that the storage tank 1 can store a larger volume of anti-corrosion paint.

[0022] In one embodiment of this application, preferably, an inflation valve 9 is fixedly connected to the top of the gas tank 7, and a piston plate 10 that slides up and down under the action of pressure difference is provided in the storage tank 1. The piston plate 10 seals and divides the storage tank 1 into a gas chamber 101 and a liquid chamber 102. Before use, the shut-off valve 5 is opened, and inert gas is filled into the gas tank 7 through the inflation valve 9 and enters the storage tank 1 through the vent hole 8. As the gas pressure in the gas tank 7 and the storage tank 1 increases, the piston plate 10 is pushed downward to discharge the air in the storage tank 1 from the discharge pipe 4. The shut-off valve 5 is closed, and the inflation stops after the inert gas in the storage tank 1 and the gas tank 7 reaches a certain pressure, keeping the gas pressure in the gas tank 7 and the storage tank 1 constant. When used for storage, anti-corrosion paint is filled in through the feed pipe 2. When filling with liquid, the piston plate 10 is compressed by the liquid pressure and the pressure difference between the liquid and the gas. When unloading, the piston plate 10 moves downward with the liquid under the action of the inert gas pressure, scraping off the anti-corrosion paint left on the inner wall of the storage tank 1. It should be noted that due to the sealing and dividing effect of the piston plate 10, the gas injected into the gas tank 7 at this time may not be an inert gas; it should also be noted that the filling valve 9 is a one-way valve, which is an existing technical structure and will not be described in detail here.

[0023] In one embodiment of this application, preferably, a guide rod 11 is fixedly connected to the top of the piston plate 10, and a guide hole (not marked in the figure) is provided on the top of the storage tank 1 for the guide rod 11 to slide out. The guide rod 11 passes through the guide hole and extends into the gas tank 7 to prevent the piston plate 10 from tilting and getting stuck in the storage tank 1, which would affect the filling and unloading of liquid.

[0024] In one embodiment of this application, preferably, the piston plate 10 has a groove 12 on its edge, and a sealing strip 13 is provided in the groove 12. The sealing strip 13 abuts against the groove 12 and the inner wall of the storage tank 1, respectively, to seal and divide the storage tank 1 to form a gas chamber 101 and a liquid chamber 102, thereby preventing gas from entering the liquid chamber 102 or liquid from entering the gas chamber 101. At the same time, it is used to scrape off the liquid on the inner wall of the storage tank 1 during unloading.

[0025] In one embodiment of this application, preferably, both the storage tank 1 and the gas tank 7 are pressure-resistant containers to ensure safe use and to prevent the storage tank 1 from undergoing large deformation under pressure and becoming mismatched with the piston plate 10.

[0026] In summary, the ship plate anti-corrosion primer storage device in the above embodiments of this utility model specifically involves opening the shut-off valve 5 on the discharge pipe 4, and filling the gas tank 7 with gas through the inflation valve 9 on the gas tank 7. The gas in the gas tank 7 enters the storage tank 1 through the vent 8. As the pressure in the gas tank 7 and the gas chamber 101 increases, it pushes the piston plate 10 to move towards the bottom of the storage tank 1, discharging the air in the liquid chamber 102 from the discharge pipe 4. When the piston plate 10 reaches the bottom of the storage tank 1, the shut-off valve 5 is closed, and after the gas pressure in the gas chamber 101 and the gas tank 7 reaches a certain value (greater than 1 standard atmosphere), the inflation valve 9 is closed. When storing anti-corrosion paint, the shut-off valve 5 is closed. The anti-corrosion paint is filled into the storage tank 1 through the one-way valve 3 of the feed pipe 2. As the liquid level rises in the liquid chamber 102, the anti-corrosion paint pushes the piston plate 10 upward to compress the gas until the liquid and gas pressure in the storage tank 1 reaches a certain level (under safe pressure). Then, the filling stops, and the piston plate 10 isolates the air from the anti-corrosion paint. When using the anti-corrosion paint, the shut-off valve 5 of the discharge pipe 4 is opened. Under the action of the gas pressure in the gas chamber 101, the piston plate 10 is pushed downward to discharge the anti-corrosion paint from the discharge pipe 4. When the piston plate 10 moves downward, it scrapes off the anti-corrosion paint remaining on the inner wall of the storage tank 1. When not in use, the shut-off valve 5 can be closed. There is no need to consider the secondary sealing problem, and the storage effect is good.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
