Description

Technical Field

[0001] This invention relates to the field of dispersion tank technology, and in particular to an apparatus for preparing anti-corrosion and anti-rust water-based paint slurry and its usage method. Background Technology

[0002] Water-based paint is a type of paint that uses water as a diluent and does not contain organic solvents. It is free of benzene, toluene, xylene, formaldehyde, free TDI, and toxic heavy metals. It is non-toxic, odorless, harmless to the human body, and does not pollute the environment. The paint film is full, crystal clear, and flexible, and it is also water-resistant, wear-resistant, aging-resistant, yellowing-resistant, fast-drying, and easy to use.

[0003] In the traditional production and dispersion process of water-based paints, a small amount of filler is not completely dispersed, resulting in many large particulate impurities in the paint after production. Therefore, it is necessary to filter and remove impurities before filling and packaging the product. This not only lengthens the production process, but also requires more manpower and financial resources, increasing production costs.

[0004] Chinese Patent CN215586235U discloses a water-based paint dispersion device. This device uses a second motor to drive a rotating rod, causing a crushing blade to crush and grind larger particles within the water-based paint, thus preventing an uneven paint surface. While this technical solution uses a crushing blade to break up filler particles and improve their dispersion and dissolution, the high-speed rotation of the crushing blade limits its effectiveness, especially when the filler particles are mixed in a liquid. This results in the crushing blade being ineffective when the filler particles are small, failing to meet the required crushing degree. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that filler particles cannot be completely crushed during the processing of water-based paint slurries in the prior art, which leads to lengthy slurry processing procedures and increased input costs. The invention proposes a device for preparing anti-corrosion and anti-rust water-based paint slurries and its usage method.

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

[0007] A device for preparing anti-corrosion and anti-rust water-based paint slurry includes a tank body, a cover detachably installed on the top of the tank body, a feed inlet provided on the cover body, a discharge pipe provided at the bottom of the tank body, a central shaft rotatably mounted coaxially inside the tank body, a motor fixedly mounted at the bottom of the tank body, a rotating ring rotatably sealed at the bottom of the tank body, multiple uprights vertically mounted on the top surface of the rotating ring, a stirring element provided on the uprights, and a drive mechanism for driving the rotating ring and the central shaft to rotate provided at the output end of the motor.

[0008] A filter cover is fitted over the central shaft, and the filter cover is fixedly connected to the central shaft by multiple fixing rods. A gap is reserved between the bottom end of the filter cover and the bottom of the tank to form a liquid inlet space. Multiple blades are fixedly arranged at equal intervals on the outer wall of the central shaft, and the blades are located at the bottom end of the filter cover. An installation frame is fixedly installed on the cover, and the installation frame extends above the blades. Multiple crushing components are longitudinally installed on the installation frame. The multiple crushing components are arranged in a circular array around the central shaft. Magnets are provided on the outer wall of the central shaft and on the opposite side of the filter cover. When the central shaft rotates and drives the filter cover to rotate, the crushing components vibrate.

[0009] Preferably, the filter cover includes a guide tube, a filter screen, a positioning ring, and multiple guide plates. The guide tube is located at the bottom and is fixedly connected to the central axis. The positioning ring is rotatably connected to the cover. The multiple guide plates are fixedly disposed between the guide tube and the positioning ring. The filter screen is disposed inside the annular structure formed by the multiple guide plates.

[0010] Preferably, the cross-section of the diversion plate is arc-shaped, and multiple diversion plates are arranged in a circular array around the guide tube.

[0011] Preferably, the crushing assembly includes a spiral blade and two springs, with the two springs respectively fixed to both ends of the spiral blade.

[0012] Preferably, the cross-section of the spiral blade is rhomboid, and two adjacent crushing components are close to each other.

[0013] Preferably, the stirring component includes a plurality of stirring blades fixedly disposed on the side wall of the upright, the stirring blades being inclined so that the stirring blades form a positive angle with the forward direction.

[0014] Preferably, the stirring component includes a stirring blade arranged in a spiral shape, which is supported by multiple uprights.

[0015] Preferably, a limiting groove is formed inside the tank, and a limiting ring is fixedly provided on the outer wall of the central shaft. The limiting ring is located in the limiting groove and is rotatably connected to the limiting groove.

[0016] Preferably, the drive mechanism includes a drive gear fixedly mounted on the motor output shaft, a driven gear fixedly mounted on the outer wall of the central shaft, and a toothed ring provided on the inner wall of the rotating ring. Both the driven gear and the toothed ring are meshed with the drive gear.

[0017] Preferably, the bottom of the tank is provided with a guide ring groove, and the inner wall of the rotating ring is provided with a retaining ring that is rotatably connected to the guide ring groove. The retaining ring is provided with a plurality of guide wheels, and the guide wheels abut against the inner wall of the guide ring groove.

[0018] A method for using an anti-corrosion and rust-preventive water-based paint slurry preparation device includes the following steps:

[0019] S1: Material addition, liquid materials such as water, dispersant, defoamer, and preservative are added into the tank through the feed inlet;

[0020] S2: Disperse and stir evenly, start the motor, the motor drives the drive gear to rotate, which in turn drives the driven gear and gear ring to rotate. The driven gear drives the central shaft to rotate, and the gear ring drives the stirring component to rotate, thus stirring and dispersing the mixture. While stirring, add the coloring pigment and extender pigment in sequence and accelerate the dispersion for 20 to 40 minutes.

[0021] S3: The filler particles are crushed in two stages. When the central shaft rotates, it drives the blades to rotate, which draws the material from outside the filter cover into the filter cover. The material is then filtered through the filter cover and discharged from the filter cover again, forming a fluid circulation. The filler particles are left inside the filter cover when they pass through it. As the central shaft and the filter cover rotate, the magnet rotates around the crushing component and attracts the crushing component in different directions, causing the crushing component to vibrate at high frequency. This causes the adjacent crushing components to perform high-frequency shearing on the filler particles until the filler particles are crushed to the point that they can pass through the filter cover.

[0022] S4: After the slurry is completed, it is discharged. The slurry produced by dispersion and emulsification is discharged and collected through the discharge pipe.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. This invention uses a motor to drive a central shaft to rotate, which in turn drives the filter cover to rotate. In conjunction with a magnet and multiple vibration springs located inside the filter cover, the magnetic force of the magnet attracts the crushing component, causing it to bend and deform. As the central shaft rotates at high speed, the magnetic attraction of the magnet constantly changes, resulting in high-frequency vibration of the crushing component under constantly changing force direction. This crushes the filler particles located inside the filter cover. Compared to the existing method of crushing by rotating crushing blades, this invention has a larger blade length and allows for shearing between adjacent crushing components, resulting in higher crushing efficiency, better crushing effect, and smaller particle size. This facilitates the full dispersion of filler in the material, solving the problem in existing water-based paint slurry processing where filler particles cannot be completely crushed, leading to lengthy processing steps and increased costs.

[0025] 2. This invention uses a filter cover, blades, and a flow guide plate to work together to allow liquid materials to circulate within the tank. The filter screen intercepts the filler particles, which are then crushed by the crushing component. This facilitates thorough dispersion of the materials within the tank. Furthermore, the flow guide plate throws the materials outside the filter cover outwards, which helps to accurately control the direction of material circulation within the tank.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Example 1

[0039] Reference Figure 1-2 A device for preparing anti-corrosion and anti-rust water-based paint slurry includes a tank body 1. A cover body 2 is detachably installed on the top of the tank body 1. The cover body 2 is connected to the tank body 1 by a flange. The cover body 2 can be removed by unscrewing the bolts on the flange to clean and maintain the inside of the tank body 1. A feed inlet is provided on the cover body 2 for adding materials, and a cover plate is provided on the feed inlet to ensure that the tank body 1 is in a closed state during the processing. A discharge pipe is provided at the bottom of the tank body 1, and the processed slurry is discharged through the discharge pipe. A solenoid valve is installed on the discharge pipe to facilitate the control of the opening and closing of the discharge pipe.

[0040] Reference Figure 2-4 A central shaft 3 is coaxially rotatably installed inside the tank body 1. The central shaft 3 passes through the tank body 1. A limiting groove is opened inside the tank body 1. A limiting ring is fixedly installed on the outer wall of the central shaft 3. The limiting ring is located in the limiting groove and is rotatably connected to the limiting groove. By cooperating with the limiting groove, the limiting ring axially limits the central shaft 3, ensuring the stability of the rotation of the central shaft 3 and reducing the risk of axial displacement of the central shaft 3.

[0041] Reference Figure 2 The bottom of the tank 1 is sealed with a rotating ring 10. Multiple uprights are vertically installed on the top surface of the rotating ring 10. Agitators are installed on the uprights to mix and stir the materials, so that the solutes in the materials are fully dispersed in the liquid materials, which is beneficial to improving the quality of the slurry. A motor 9 is fixedly installed at the bottom of the tank 1. The motor 9 is the power source of this device. The output end of the motor 9 is equipped with a drive mechanism for driving the rotating ring 10 and the central shaft 3 to rotate. After the motor 9 is started, it drives the central shaft 3 and the rotating ring 10 to rotate through the drive mechanism.

[0042] Reference Figure 2-4A filter cover 4 is fitted around the central shaft 3. The filter cover 4 is fixedly connected to the central shaft 3 by multiple fixing rods, forming a rigid structure. When the central shaft 3 rotates, it drives the filter cover 4 to rotate synchronously. A gap is reserved between the bottom of the filter cover 4 and the bottom of the tank 1 to form a liquid inlet space. Multiple equally spaced blades 5 are fixedly installed on the outer wall of the central shaft 3. The blades 5 are located at the bottom of the filter cover 4. When the motor 9 drives the central shaft 3 to rotate, it drives the blades 5 to rotate. The blades 5 drive the liquid material to flow upward into the filter cover 4. The liquid inlet space below the blades 5 forms a negative pressure, causing the material outside the filter cover 4 to flow into the liquid inlet space for replenishment. The material entering the filter cover 4 is filtered inside the filter cover 4 and then discharged from the filter cover 4, forming a continuous cycle. This causes the filler particles in the mixture to collect inside the filter cover 4, which is beneficial for subsequent crushing operations.

[0043] Reference Figure 3-4 The filter cover 4 includes a guide pipe 41, a filter screen 42, a positioning ring 43, and multiple guide plates 44. The guide pipe 41 is located at the bottom and is fixedly connected to the central shaft 3. By setting the guide pipe 41, it is beneficial for the blades 5 to drive the material to flow in a directional manner to form a circulation. The positioning ring 43 is rotatably connected to the cover 2. A positioning groove is opened at the top of the cover 2. The positioning ring 43 is located in the positioning groove and is rotatably connected to the positioning groove to ensure the stability of the rotation of the central shaft 3 and the filter cover 4. Multiple guide plates 44 are fixedly set between the guide pipe 41 and the positioning ring 43. The filter screen 42 is set inside the annular structure formed by multiple guide plates 44. The guide plates 44 can ensure the connection strength between the positioning ring 43 and the guide pipe 41, and prevent the filter screen 42 from deforming due to excessive torque when the filter cover 4 rotates, which would affect the filtration effect. In addition, the guide plates 44 generate centrifugal force when rotating with the central shaft 3, which throws the material outside the filter screen 42 out, reducing the risk of material flowing back into the filter screen 42 and affecting the circulation direction of the material.

[0044] Reference Figure 3-5An installation frame 6 is fixedly installed on the cover 2. The installation frame 6 is divided into two hollowed-out installation pieces, which are fixedly connected by a connecting post. The connecting post extends to the bottom of the cover 2 and is fixedly connected to the cover 2. The installation frame 6 extends above the blade 5. Multiple crushing components 7 are longitudinally installed on the installation frame 6. The crushing components 7 are located between the two installation pieces and are arranged in a circular array around the central axis 3. Magnets 8 are provided on the outer wall of the central axis 3 and on the opposite side of the filter cover 4. When the central axis 3 rotates and drives the filter cover 4 to rotate, the crushing components 7 vibrate. The crushing components 7 are attracted by the magnets 8. Under the action, deformation and bending will occur. As the central shaft 3 and the filter cover 4 rotate, the position of the magnet 8 changes continuously. Therefore, the direction of the attraction of the magnet 8 to the crushing component 7 also changes continuously, causing the crushing component 7 to vibrate. As the rotation speed of the central shaft 3 and the filter cover 4 increases, the vibration frequency of the crushing component 7 also increases. The high-frequency vibrating crushing component 7 quickly crushes the filler particles collected in the filter cover 4 until the particles are dispersed and dissolved in the material. With the circulation of the material, it is carried out of the filter cover 4, which is beneficial to improve the production quality of the slurry, reduce the filtration steps in slurry processing and the waste of materials, and reduce production costs.

[0045] Reference Figure 6 The crushing component 7 includes a spiral blade 71 and two springs 72. The two springs 72 are fixed at both ends of the spiral blade 71, so that the magnet 8 attracts the spiral blade 71 when it approaches the magnet 8, causing the spiral blade 71 to move closer to the magnet 8. At this time, the springs 72 bend and deform. Since the magnets 8 located at the same horizontal position are set on the opposite side walls of the central shaft 3 and the filter screen 42, when the central shaft 3 drives the filter cover 4 to rotate, the same spiral blade 71 is attracted by different magnets 8, so that the spiral blade 71 is attracted by different directions in the radial direction. Therefore, the crushing component 7 can be made to swing back and forth, thereby increasing the vibration amplitude of the crushing component 7 and improving the crushing effect on the filler particles.

[0046] In the above description, magnet 8 is a neodymium magnet, and spiral blade 71 is a ferromagnetic blade. The rotation of the central shaft 3 drives the filter cover 4 to rotate synchronously. The magnet 8 located on the side wall of the central shaft 3 attracts the spiral blade 71, causing the spiral blade 71 to move radially toward the central shaft 3 and bend the spring 72. Since the magnet 8 on the filter cover 4 is far away from the spiral blade 71, it does not affect the spiral blade 71. When the central shaft 3 rotates 180°, the magnet 8 on the central shaft 3 moves away from the spiral blade 71, and the attraction to the spiral blade 71 decreases, no longer affecting the spiral blade 71. At the same time, the magnet 8 on the filter cover 4 moves closer to the spiral blade 71, causing the spiral blade 71 to move radially away from the central shaft 3. With the high-speed rotation of the central shaft 3, the spiral blade 71 performs high-frequency reciprocating oscillation. Multiple spiral blades 71 cooperate with each other to form a crushing and grinding effect on the filler particles.

[0047] Reference Figure 7 The cross-section of the spiral blade 71 is rhomboid, which gives the outer edge of the spiral blade 7 a certain sharpness, making it more conducive to crushing particles. Two adjacent spiral blades 7 are close to each other. As can be seen from the above technical solution, multiple spiral blades 7 are attracted by the magnet 8, which causes the spring 72 to deform and thus generate vibration. When the spiral blades 7 vibrate, the order of swing of each spiral blade 7 is affected by the position of the magnet 8. Therefore, the swing directions of two adjacent spiral blades 7 are not completely consistent. Thus, a shearing effect is formed between two adjacent spiral blades 7, which is beneficial to crushing particles and improving the dispersion effect of materials.

[0048] The cross-section of the flow guide plate 44 is arc-shaped, and multiple flow guide plates 44 are arranged in a circular array around the flow guide tube 41. The arc-shaped flow guide plate 44 is conducive to improving the centrifugal effect on the liquid material and ensuring the fluid circulation.

[0049] Reference Figure 8 The mixing component includes multiple mixing blades 11 fixedly mounted on the side wall of the uprights. The rotating ring 10 rotates, causing multiple uprights to rotate around the central axis of the tank 1, and simultaneously causing the mixing blades 11 to rotate, thereby agitating the material inside the tank 1 and dispersing the material. The mixing blades 11 are inclined, forming a positive angle with the direction of travel. While the mixing blades 11 rotate and agitate the material, they also apply downward pressure to the material, causing it to flow downwards. This facilitates the circulation of material in the tank 1 and improves the mixing and dispersion effect of the material.

[0050] Reference Figure 2The drive mechanism includes a drive gear 91 fixedly mounted on the output shaft of the motor 9. After the motor 9 starts, it drives the drive gear 91 to rotate. A driven gear 31 is fixedly mounted on the outer wall of the central shaft 3. A gear ring 12 is provided on the inner wall of the rotating ring 10. Both the driven gear 31 and the gear ring 12 are meshed with the drive gear 91. When the drive gear 91 rotates, it drives the gear ring 12 and the driven gear 31 to rotate respectively. The gear ring 12 drives the rotating ring 10 to rotate, thereby agitating the material. The driven gear 31 drives the central shaft 3 to rotate, thereby changing the direction of the attraction force of the magnet 8 and causing the crushing component 7 to vibrate. At the same time, it causes the blades 5 to rotate, forming a material circulation flow.

[0051] The number of effective teeth of the drive gear 91 is greater than that of the driven gear 31, so that when the motor 9 rotates, the drive center shaft 3 rotates at a faster speed, ensuring the fluid conveying performance of the blade 5 and improving the vibration frequency of the crushing component 7, thereby improving the crushing and dispersing effect and thus improving the quality of the slurry.

[0052] Reference Figure 2 The bottom of the tank body 1 is provided with a guide ring groove. The inner wall of the rotating ring 10 is provided with a retaining ring 13 that is rotatably connected to the guide ring groove. Multiple guide wheels 14 are provided on the retaining ring 13. The guide wheels 14 abut against the inner wall of the guide ring groove. Through the cooperation between the guide ring groove and the retaining ring 13, the rotating ring 10 is axially limited, which improves the stability of the rotating ring 10 and reduces the risk of the rotating ring 10 deviating. In addition, by setting the guide wheels 14, the friction between the rotating ring 10 and the tank body 1 is reduced, which improves the flexibility of the rotation of the rotating ring 10.

[0053] Example 2

[0054] Reference Figure 9 The mixing component includes a spirally arranged mixing blade 15, which is supported by multiple uprights. The rotating ring 10 rotates, causing the uprights to rotate around the central axis of the tank 1, simultaneously rotating the mixing blade 15 to agitate and disperse the material within the tank 1. Because the mixing blade 15 is spirally arranged, its rotation promotes material flow, ensuring uniform mixing and guaranteeing the quality of the slurry.

[0055] A method for using an anti-corrosion and rust-preventive water-based paint slurry preparation device includes the following steps:

[0056] S1: Material addition: Liquid materials such as water, dispersant, defoamer, and preservative are added into tank 1 through the feed inlet;

[0057] S2: Disperse and stir evenly, start motor 9, motor 9 drives drive gear 91 to rotate, which in turn drives driven gear 31 and gear ring 12 to rotate. Driven gear 31 drives central shaft 3 to rotate, and gear ring 12 drives stirring component to rotate, stirring and dispersing the mixture. In the stirring state, color pigment and extender pigment are added in sequence and dispersed for 30 minutes.

[0058] S3: The filler particles are crushed in a secondary manner. When the central shaft 3 rotates, it drives the blades 5 to rotate, so that the material is drawn from the outside of the filter cover 4 into the filter cover 4. The material is filtered through the filter cover 4 and then discharged from the filter cover 4 again, forming a fluid circulation. The filler particles are left in the filter cover 4 when they pass through it. As the central shaft 3 and the filter cover 4 rotate, the magnet 8 rotates around the crushing component 7 and attracts the crushing component 7 in different directions, causing the crushing component 7 to vibrate at high frequency. This causes the adjacent crushing components 7 to perform high-frequency shearing on the filler particles until the filler particles are crushed to the point that they can pass through the filter cover 4.

[0059] S4: After the slurry is completed, it is discharged. The slurry produced by dispersion and emulsification is discharged and collected through the discharge pipe.

[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

In the stirring state, the coloring pigment and the extender pigment are added in sequence, and the dispersion is accelerated for 20 to 40 minutes. S3: The filler particles are crushed in the second stage. When the central shaft (3) rotates, it drives the blades (5) to rotate, so that the material is drawn from the outside of the filter cover (4) into the filter cover (4). The material is filtered through the filter cover (4) and discharged from the filter cover (4) again, forming a fluid circulation. The filler particles are left in the filter cover (4) when they pass through the filter cover (4). As the central shaft (3) and the filter cover (4) rotate, the magnet (8) rotates around the crushing component (7) and attracts the crushing component (7) in different directions, so that the crushing component (7) vibrates at high frequency, and then the adjacent crushing components (7) perform high frequency shearing on the filler particles until the filler particles are crushed to the point that they can pass through the filter cover (4). S4: After the slurry is completed, it is discharged. The slurry produced by dispersion and emulsification is discharged and collected through the discharge pipe.
