Description

Technical Field

[0001] This utility model relates to the field of coating stirring and dispersion technology, specifically a stirring and dispersion kettle for preparing marine coatings. Background Technology

[0002] Marine coatings are specialized coatings designed specifically for ships to protect the hull from damage such as seawater corrosion, marine organism adhesion, and UV aging. They possess excellent anti-rust, antifouling, and weather-resistant properties, effectively extending the service life of ships and reducing maintenance costs. Marine coatings come in various types, including anti-rust paint, antifouling paint, bottom paint, and deck paint, each suitable for different parts of the hull. Antifouling paint prevents the adhesion of organisms such as barnacles and algae, reducing navigational resistance; anti-rust paint forms a dense protective film, isolating seawater from contact with metal. Modern marine coatings also emphasize environmental protection, with low-toxicity and low-volatile organic compound formulations becoming the trend to reduce the impact on the marine ecosystem.

[0003] The dispersion kettle is mainly suitable for mixing high-viscosity coatings, inks, adhesives, putty, body filler, stone paint and other chemical products. Its mechanism is that the stirring motor rotates and drives the stirring rod to stir the materials, so that the materials can be uniformly mixed and dispersed.

[0004] Because marine coatings have a high viscosity, the dispersion vessel experiences significant resistance during agitation. This prevents the stirring structure from rotating at high speeds to utilize shear force for mixing. Low-speed stirring makes it difficult to achieve uniform mixing of the coating, especially between adjacent stirring blades, where uneven mixing is likely to occur. Therefore, we propose a stirred dispersion vessel for preparing marine coatings. Utility Model Content

[0005] The purpose of this invention is to provide a stirring and dispersing vessel for preparing marine coatings. By setting up a lifting plate inside the vessel, multiple lifting plates are located between adjacent stirring blades and have through holes on their surfaces. During the stirring process, the lifting plates rise and fall, which can bring the coating upwards so that it is stirred by the stirring blades. The through holes on their surfaces also achieve stirring of the coating, so that the coating can be stirred efficiently and evenly, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stirring and dispersing vessel for preparing marine coatings, comprising a tank body, a rotating rod, and a lifting plate. The rotating rod is vertically rotatably installed inside the tank body and is connected to a motor mounted on the top surface of the tank body. Stirring blades are fixed on both sides of the outer ring of the rotating rod, and the stirring blades are evenly spaced in the vertical direction. A lifting plate is provided above the stirring blades other than the uppermost stirring blade. The upper and lower lifting plates are connected by a connecting rod on the outer ring. The outer ring of the lifting plate is in contact with the inner wall surface of the tank body, and the rotating rod passes through the rod hole in the middle of the lifting plate and slidably contacts the rod hole. A second through hole is evenly opened on the surface of the lifting plate. Electric push rods are vertically installed on both sides of the top of the tank body. The protruding ends of the electric push rods pass through the inside of the tank body and are fixed on both sides of the surface of the uppermost lifting plate.

[0007] By adopting the above technical solution, the coating is placed inside the tank and stirred by the stirring blades. At the same time, the lifting plate rises and falls. Taking advantage of the high viscosity of the coating, the coating cannot quickly pass through the second through hole to the bottom of the lifting plate. As a result, the coating can be continuously driven upward and stirred by the stirring blades above. Combined with the stirring action when the coating passes through the second through hole, the coating can be efficiently and evenly stirred and dispersed.

[0008] Optionally, when the electric actuator is fully retracted, the lifting plate rises to its highest position and is close to the lower part of the stirring blade above it; when the electric actuator is fully extended, the lifting plate lowers to its lowest position and is close to the upper part of the stirring blade below it.

[0009] By adopting the above technical solution, the travel of the electric actuator is used to achieve the purpose of limiting the movement and avoid contact between the lifting plate and the stirring blade.

[0010] Optionally, the surface of the stirring blade is provided with a first through hole, which is evenly distributed on the surface of the stirring blade.

[0011] By adopting the above technical solution, the coating passes through the first through hole and the stirring blade, which improves the stirring effect of the coating.

[0012] Optionally, a feed pipe is connected to the upper side of the tank, and the feed pipe communicates with the interior of the tank.

[0013] By adopting the above technical solution, the raw materials are added into the tank through the feed pipe.

[0014] Optionally, a discharge pipe is connected to the middle of the bottom of the tank, and the discharge pipe communicates with the inside of the tank.

[0015] By adopting the above technical solution, the mixed coating is discharged from the discharge pipe.

[0016] Optionally, tapered guide holes are provided on the surfaces of the lifting plates above and below the second through hole, and these tapered guide holes are connected to the second through hole.

[0017] By adopting the above technical solution, the coating can be guided and pass smoothly through the second through hole whether it is from above or below.

[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 is to install lifting plates inside the tank. Multiple lifting plates are located between adjacent stirring blades and have through holes on their surfaces. During the stirring process, the lifting plates rise and fall, which can bring the coating upward and make it agitated by the stirring blades. Combined with the agitation effect when the coating passes through the second through hole, the coating can be efficiently and fully agitated.

[0022] 2. The technical solution of this application has a first through hole on the surface of the stirring blade. When the stirring blade rotates, the coating can also pass through the first through hole and thus improve the stirring effect of the coating. Attached Figure Description

[0029] Please see Figure 1-4 This utility model provides a technical solution: a stirring and dispersing kettle for preparing marine coatings, including a tank body 1, a rotating rod 2, and a lifting plate 4. The bottom outer ring of the tank body 1 is vertically supported by legs 13. Multiple legs 13 are provided, and each leg 13 is of the same height, which can achieve vertical stability support for the tank body 1. A feed pipe 11 is connected to the upper side of the tank body 1. The feed pipe 11 is connected to the inside of the tank body 1. Multiple feed pipes 11 can be provided to connect to the raw material supply pipeline and add the raw materials for coating production into the tank body 1. A discharge pipe 12 is connected to the middle of the bottom of the tank body 1. The discharge pipe 12 is connected to the inside of the tank body 1. When in use, a valve is installed to block the discharge pipe 12. After the coating is stirred, the valve can be opened to allow the coating to be discharged from the discharge pipe 12.

[0030] To achieve the purpose of stirring and mixing the coating, the rotating rod 2 is vertically rotatable and installed inside the tank 1. The rotating rod 2 is connected to the motor 22 installed on the surface of the top of the tank 1. Stirring blades 21 are fixed on both sides of the outer ring of the rotating rod 2. The stirring blades 21 are evenly spaced in the vertical direction. When the coating raw materials are added, the motor 22 is started to drive the rotating rod 2 and make the stirring blades 21 rotate, which can achieve the purpose of stirring and dispersing the coating. In order to improve the stirring effect, a first through hole 211 is opened on the surface of the stirring blade 21. The first through hole 211 is evenly distributed on the surface of the stirring blade 21. During stirring, the coating can also pass through the first through hole 211 and pass through the stirring blade 21, which can improve the stirring effect of the coating.

[0031] With the above structural design, due to the high viscosity of the coating, the rotation speed of the stirring blade 21 is affected. In addition, the coating between the upper and lower stirring blades 21 may not be fully stirred. To solve this problem, in this application: a lifting plate 4 is provided above the stirring blades 21 other than the uppermost stirring blade 21. Each lifting plate 4 has the same size, and the upper and lower lifting plates 4 are connected by a connecting rod 41 on the outer ring. At the same time, the outer ring of the lifting plate 4 is in contact with the inner wall surface of the tank 1. A through rod hole 42 is opened in the middle of the lifting plate 4, so that the rotating rod 2 passes through the rod hole 42 in the middle of the lifting plate 4. The rotating rod 2 can slide in contact with the rod hole 42. A through second through hole 43 is also evenly opened on the surface of the lifting plate 4. Electric push rods 3 are vertically installed on both sides of the top of the tank 1. The protruding end of the electric push rod 3 passes through the inside of the tank 1 and is fixed on both sides of the surface of the uppermost lifting plate 4.

[0032] While the stirring blade 21 rotates and agitates the coating, the electric actuator 3 drives multiple lifting plates 4 to move up and down synchronously. The lifting plates 4 move up and down between adjacent stirring blades 21. Because the coating is highly viscous, it will not pass through the second through hole 43 on the surface of the lifting plate 4 quickly. The lifting plate 4 can lift the coating to a higher height, so that the coating at the lower layer is carried to the upper layer and is agitated at the position of the stirring blade 21. Afterwards, the coating will fall down again through the second through hole 43. The coating can be agitated again by the action of the coating through the second through hole 43 on the surface of the lifting plate 4. Then the lifting plate 4 is driven down to a lower height, so that the coating at the lower level passes through the second through hole 43 to the upper plate of the lifting plate 4 and mixes the coating again. In the above way, the coating can be efficiently and evenly agitated and dispersed.

[0033] In addition, tapered guide holes are provided on the surfaces of the lifting plates 4 above and below the second through hole 43. These tapered guide holes are connected to the second through hole 43, so that the paint can be guided and pass smoothly when it passes through the second through hole 43 from above or below.

[0034] To prevent the lifting plate 4 from contacting and interfering with the stirring blade 21 during lifting and lowering, a limiting structure is required. The limiting purpose is achieved by utilizing the stroke of the electric push rod 3. That is, when the electric push rod 3 is fully retracted, the lifting plate 4 rises to the highest position and is close to the lower part of the stirring blade 21 above it. When the electric push rod 3 is fully extended, the lifting plate 4 lowers to the lowest position and is close to the upper part of the stirring blade 21 below it. This can prevent the lifting plate 4 from contacting the stirring blade 21 above or below it.

[0035] In use, a valve is installed on the feed pipe 11 and connected to the raw material supply pipeline, and a valve is installed on the discharge pipe 12 and connected to the conveying pipeline. The motor 22 and the electric push rod 3 are connected to the industrial control computer. First, the raw material is injected into the tank 1 through the feed pipe 11. After the raw material leaks down through the second through hole 43 on the surface of the lifting plate 4, the stirring and dispersion work begins. The motor 22 is started to drive the rotating rod 2 and the stirring blade 21 to rotate. The stirring blade 21, in conjunction with the first through hole 211 on its surface, achieves uniform stirring and dispersion of the coating in the area through which the stirring blade 21 passes. In order to achieve high efficiency and uniform stirring in all places, the electric push rod 3 also drives multiple lifting plates 4 to repeatedly move up and down during the stirring process. The lifting plates 4 move up and down between adjacent stirring blades 21. Because the coating is highly viscous, it will not pass through the lifting plates quickly. The second through hole 43 on the surface of plate 4 allows the lifting plate 4 to lift the coating material to a higher height, bringing the coating material from the lower layer to the upper layer and agitating it at the position of the stirring blade 21. The coating material then falls back down through the second through hole 43, agitating it again. Afterward, the lifting plate 4 is lowered, allowing the coating material to pass through the second through hole 43 to the upper plate of the lifting plate 4, where it is mixed again. In this way, the coating material can be efficiently and evenly stirred and dispersed. After stirring is complete, the operation of the motor 22 and the electric push rod 3 is stopped, and the valve installed on the discharge pipe 12 is opened, allowing the coating material to be discharged from the bottom discharge pipe 12 to the outside and transported by the conveying pipe.
