Description

Technical Field

[0001] The present invention relates to the technical field of coating preparation, and in particular to a device and method for preparing a water-based environmentally friendly anti-corrosion coating. Background Art

[0002] Water-based environmentally friendly anti-corrosion coating is an environmentally friendly coating. It uses water as solvent or dispersion medium and has the characteristics of being non-toxic, odorless, and abundant in resources. It can greatly reduce the pollution to the atmosphere caused by the volatilization of organic solvents in the coating. Now water-based environmentally friendly anti-corrosion coating has been successfully used in many fields, including architectural decoration, automobile manufacturing, ship and container manufacturing, railway locomotives, aerospace, transportation bridges and wood coating, etc. In infrastructure construction, such as the anti-corrosion protection of roads, railways, bridges, tunnels and other projects, water-based environmentally friendly anti-corrosion coating has also played an important role.

[0003] The preparation process of water-based environmentally friendly anti-corrosion coatings includes four process steps: emulsification and dispersion, stirring and mixing, dilution and adjustment, and impurity filtration. The existing preparation equipment for water-based environmentally friendly anti-corrosion coatings can basically meet the use needs of daily production, but there are still some shortcomings, mainly manifested in:

[0004] First, the emulsification and dispersion mechanism of the existing preparation device has a simple structure. During the emulsification process, the vibration generated by the high-speed rotation of the dispersion frame will be transmitted to the column structure of the mechanism, causing serious noise pollution;

[0005] Second, the stirring structure of the existing preparation device is simple. Due to the limitation of the structure, the stirring frame carried by the device cannot be adjusted during the stirring process, which affects the uniformity of the material mixing during the stirring and mixing process.

[0006] Third, the existing preparation device relies on manual experience to adjust the dosage when adding diluent to adjust the viscosity of the coating. Human errors are prone to occur during the dilution process, which affects the accuracy of adding diluent.

[0007] Fourth, the existing device has a single functionality and lacks the function of cleaning the filter. In the continuous production process, in order to prevent the filter from being clogged and affecting the filtration efficiency, manual cleaning needs to be arranged during the production intervals, which increases the labor intensity of the staff.

[0008] Therefore, it is of great significance to design a device and method for preparing a water-based environmentally friendly anti-corrosion coating. Summary of the invention

[0033] The locking cylinder drives the locking head to disengage from the locking block, thereby releasing the fixation of the column base and the upper support;

[0034] The transmission motor is started, and the dispersion rack is driven to rotate at high speed through the driving wheel, the driven wheel and the transmission belt to emulsify and disperse the base material; during this process, the vibration generated by the dispersion rack is buffered and isolated by the damper, the support spring and the side spring in the seismic isolation support assembly;

[0035] c. Stir and mix:

[0036] Discharge the emulsified and dispersed base material into the stirring shell of the mixing and stirring assembly through the stirring discharge pipe and the discharge pump;

[0037] Add zinc powder, anti-rust pigment, leveling agent, corrosion inhibitor, dispersant, curing agent and water into the mixing shell;

[0038] Start the stirring motor to drive the stirring frame to rotate and stir and mix the base material, filler, additive and solvent;

[0039] During the stirring process, the stirring adjustment component automatically adjusts the position of the stirring frame in the stirring shell to improve the mixing uniformity;

Specifically, the damper is composed of an upper support, a lower support and a damping fluid, and the upper support is slidably connected in the damping fluid, and cooperates with the support spring and the side spring to form an elastic connection structure.

[0054] The seismic isolation design reduces the impact and stress on the equipment, improves the stability and service life of the equipment; the seismic isolation support components effectively buffer the vibration generated by the high-speed rotation of the dispersion frame, reduce the vibration transmission to the equipment base and the surrounding environment, and significantly reduce the equipment operation noise.

At the same time, the adjustment cylinder drives the rotating frame to move along the adjustment frame, thereby driving the position of the stirring frame in the stirring shell to change.

[0056] The automatic adjustment of the stirring rack position ensures the uniformity of the mixing process and improves the consistency of the coating quality. The effective range of the stirring rack is expanded, the stirring efficiency is improved, and the uniformity of the coating is further ensured. Automatic adjustment reduces manual intervention, speeds up the stirring process, and improves overall production efficiency.

[0058] Precisely controlling the amount of thinner added ensures stable viscosity of the coating, improves the stability and reliability of the coating, reduces the waste of raw materials, and reduces production costs.

[0059] Fourth, the present invention designs a filter cleaning assembly, which realizes automatic cleaning of the filter through components such as a flip motor, a push cylinder, and a cleaning motor. Specifically, the flip motor drives the filter to flip, the push cylinder pushes the cleaning frame into the filter, and the cleaning motor drives the cleaning frame to rotate for cleaning.

[0060] It reduces manual participation and reduces the labor intensity of workers in the continuous production process. It ensures the continuity of production and improves the overall production efficiency. Regular cleaning of the filter ensures the filtering effect and avoids the problem of filter clogging affecting the quality of the coating.

[0061] Fifth, the present invention designs process links such as emulsification and dispersion, stirring and mixing, dilution and adjustment, and impurity filtering. The entire preparation process and each link are closely connected to form an efficient and precise method for preparing water-based environmentally friendly anti-corrosion coatings, which improves the preparation efficiency of the coatings, ensures the quality stability and consistency of the coatings, reduces raw material waste and labor costs, reduces production costs, and is conducive to the efficient production of high-quality coating products.

[0138] Example 1. This example will describe a method for preparing a water-based environmentally friendly anti-corrosion coating in combination with an application case. The raw materials of the water-based environmentally friendly anti-corrosion coating used in this example are 30 parts of water-based polyurethane resin, 50 parts of acrylic copolymer, 12 parts of inorganic silicate, 6 parts of zinc powder, 68 parts of anti-rust pigment, 3 parts of leveling agent, 3 parts of corrosion inhibitor, 4 parts of dispersant, 2 parts of curing agent and 250 parts of water.

[0139] In this embodiment, a method for preparing a water-based environmentally friendly anti-corrosion coating is divided into the following stages:

[0140] 1. Emulsification and dispersion stage;

[0141] Adding base material: First, a base material consisting of waterborne polyurethane resin, acrylic copolymer and inorganic silicate is added into the dispersion box 30 .

[0142] Locking and isolation preparation:

[0143] The locking head 26 is driven to disengage from the locking block 27 by the locking cylinder 25 .

[0144] When the locking head 26 is completely separated from the locking block 27 , the seismic isolation support assembly 2 (including the damper 21 , the support spring 22 , the side spring 23 , etc.) forms an elastic connection structure between the column base 31 and the upper support 32 .

[0145] Decentralized processing:

[0146] The transmission motor 38 is started, and the transmission structure consisting of the driving wheel 35, the driven wheel 36 and the transmission belt 37 drives the dispersion rack 39 to rotate at a high speed.

[0147] During the dispersion process, the vibration generated by the upper support 32 is effectively buffered by squeezing and stretching the support spring 22 and the side spring 23, thereby achieving a seismic isolation effect.

[0148] This vibration isolation mechanism prevents the high-speed rotating dispersion frame 39 from transmitting vibration to the column base 31, thereby reducing the operating noise of the equipment.

[0149] 2. Mixing and stirring stage;

[0150] Base material discharge and mixing:

[0151] The emulsified and dispersed base material is discharged into the stirring shell 41 through the stirring discharge pipe 44 under the action of the discharge pump 45 .

[0152] Subsequently, zinc powder, anti-rust pigment, leveling agent, corrosion inhibitor, dispersant, curing agent and water are added to the stirring shell 41 .

[0153] The stirring motor 42 is started to drive the stirring frame 43 to rotate, so that the base material, filler, additive and solvent are mixed with each other in the stirring shell 41.

[0154] Automatic adjustment of stirring position:

[0155] The gear motor 59 drives the adjusting gear 58 to rotate, and utilizes the meshing action between the adjusting gear 58 and the supporting gear ring 51 to drive the supporting gear ring 51 and the arc-shaped bracket 52 to rotate on the stirring shell 41 .

[0156] At the same time, the adjusting cylinder 56 drives the rotating frame 55 to move along the adjusting frame 57. During the movement, the sliding frame 54 is driven to slide in the sliding groove 53 through the sliding connection between the rotating frame 55 and the stirring frame 43, and the position of the stirring frame 43 in the stirring shell 41 is automatically adjusted.

[0157] This automatic adjustment mechanism expands the effective range of the stirring frame 43 and improves the uniformity of material mixing under the same time.

[0158] 3. Sampling, testing and dilution adjustment stage;

[0159] Sampling test:

[0160] Before adding diluent to adjust the viscosity of the paint, the stirred paint stock solution is discharged into the detection shell 67 by using the sampling pump 65 for sampling.

[0161] During the sampling process, the mass change of the detection shell 67 is monitored by the pressure sensor 66 .

[0162] Diluent addition and mixing:

[0163] After the diluent is added, the rotating motor 62 drives the rotating frame 63 to rotate so that the diluent is fully mixed in the paint stock solution.

[0164] The change in the coating viscosity is monitored in real time by the detection probe 68 .

[0165] Detection probe position adjustment:

[0166] The lifting motor 73 drives the lifting gear 72 to rotate, and the mounting ring 74 moves up and down by the meshing action of the rack 71 and the lifting gear 72, so as to adjust the position of the detection probe 68 in the solution and ensure the monitoring accuracy.

[0167] Diluent addition accuracy:

[0168] The result of sampling dilution is used as the basis for adding diluent, which eliminates human errors and ensures the accuracy of diluent addition.

[0169] 4. Filtration, discharging and cleaning stage;

[0170] Filter out material:

[0171] After the diluent is added, the coating is thoroughly mixed in the stirring shell 41 .

[0172] The discharge pump 82 sucks out the paint in the stirring shell 41 and discharges it into the filter frame 85 through the discharge bucket 83 .

[0173] After being filtered by the filter frame 85 , the paint drips into the filter housing 84 , and is then discharged and filled from the discharge pipe 86 under the action of the discharge pump 87 .

[0174] Filter cleaning:

[0175] During continuous production, the filter rack 85 is turned by the turning motor 91 during the discharge interval. The push cylinder 94 pushes the cleaning rack 95 from the bottom into the filter rack 85. The driving force of the cleaning motor 98 is transmitted to the cleaning rack 95 through the cooperation between the square block 96 and the transmission sleeve 97, driving the cleaning rack 95 to rotate for automatic cleaning. The cleaned residue is discharged from the cleaning pipe 92, and there is no need for manual participation in the cleaning process, which reduces the labor intensity of the staff during the continuous production process.

[0176] The specific process is as follows:

[0177] During the emulsification and dispersion process, a base material consisting of water-based polyurethane resin, acrylic copolymer and inorganic silicate is added to the dispersion box 30, and then the locking head 26 is driven to disengage from the locking block 27 through the locking cylinder 25. After the locking head 26 is completely separated from the locking block 27, the elastic connection structure between the column base 31 and the upper support 32 is formed by the seismic isolation support assembly 2. When the transmission motor 38 drives the dispersion frame 39 to rotate at a high speed through the transmission structure consisting of the driving wheel 35, the driven wheel 36 and the transmission belt 37, the vibration generated by the upper support 32 is buffered by the extrusion and stretching support springs 22 and the side springs 23, which has a seismic isolation effect, preventing the high-speed rotating dispersion frame 39 from transmitting vibration to the column base 31, thereby reducing the operating noise of the equipment.

[0178] The emulsified and dispersed base material is discharged into the stirring shell 41 through the stirring discharge pipe 44 under the action of the discharge pump 45, and then zinc powder, rust-proof pigment, leveling agent, corrosion inhibitor, dispersant, curing agent and water are added. Then, the stirring frame 43 is driven to rotate under the action of the stirring motor 42, so that the base material, filler, additive and solvent are mixed with each other. During the mixing process, the adjusting gear 58 is driven to rotate by the gear motor 59, and the supporting gear ring 51 and the arc bracket 52 are driven to rotate on the stirring shell 41 by the meshing action of the adjusting gear 58 and the supporting gear ring 51. At the same time, the adjusting cylinder 56 drives the rotating frame 55 to move along the adjusting frame 57. During the movement, the sliding frame 54 is driven to slide in the sliding groove 53 through the sliding connection between the rotating frame 55 and the stirring frame 43, and the position of the stirring frame 43 in the stirring shell 41 is automatically adjusted, thereby expanding the effective action range of the stirring frame 43 and improving the uniformity of material mixing under the same time.

[0179] Before adding diluent to adjust the viscosity of the paint, the stirred paint stock solution is discharged into the detection shell 67 by using the sampling pump 65 for sampling. During the sampling process, the pressure sensor 66 monitors the mass change of the detection shell 67. Subsequently, the diluent is added and the rotating frame 63 is driven to rotate by the rotating motor 62 to allow the diluent to be fully mixed in the paint stock solution. The change in the viscosity of the paint is then monitored in real time by the detection probe 68. During the entire monitoring process, the lifting motor 73 drives the lifting gear 72 to rotate, and the meshing action of the rack 71 and the lifting gear 72 is used to move the mounting ring 74 up and down to adjust the position of the detection probe 68 in the solution, thereby ensuring the monitoring accuracy. At the same time, the result of the sampling dilution is used as the basis for the addition of the diluent, thereby eliminating human errors and ensuring the accuracy of the addition of the diluent.

[0180] After the diluent is added, it is fully mixed in the stirring shell 41. After mixing, the paint in the stirring shell 41 is sucked out by the discharge pump 82 and discharged into the filter frame 85 through the discharge bucket 83. After being filtered by the filter frame 85, it drips into the filter shell 84, and then is discharged and filled from the discharge pipe 86 by the discharge pump 87.

[0181] During continuous production, the filter frame 85 is driven to flip by the flip motor 91 during the discharge gap. At the same time, the cleaning frame 95 is pushed from the bottom into the filter frame 85 by the push cylinder 94. Then, the driving force of the cleaning motor 98 is transmitted to the cleaning frame 95 through the cooperation between the square block 96 and the transmission sleeve 97, driving the cleaning frame 95 to rotate. The cleaning frame 95 is automatically cleaned by the cleaning frame 95, and the cleaned residue is discharged from the cleaning pipe 92. There is no need for manual participation in the cleaning process, which reduces the labor intensity of the staff during the continuous production process.

[0182] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
