Description

Technical Field

[0001] This invention relates to the field of coating processing technology, specifically to a dilution and defoaming device and method for processing anti-corrosion coatings. Background Technology

[0002] Anti-corrosion coatings are a type of functional coating that can protect the substrate from environmental erosion and extend its service life. They prevent or slow down the damage of corrosive media to the substrate through multiple mechanisms such as physical shielding, chemical corrosion inhibition, and electrochemical protection.

[0003] For the dilution of anti-corrosion coatings, it is usually necessary to add a thinner to the coating. However, in low-temperature environments, the coating has poor flowability and is prone to increased viscosity. This can lead to poor dilution effect during stirring and dilution. Furthermore, when the volume of coating is large, the viscosity of the inner and outer sides of the coating may be inconsistent, resulting in stratification during dilution. To address this issue, we propose a dilution and defoaming device and method for anti-corrosion coating processing. Summary of the Invention

The number of side shafts is adapted to the number of lifting rods. A slide frame is sleeved on the outside of the side shaft and fixedly connected to the top of the gear ring. The slide frame is slidably connected to the side shaft.

[0008] Preferably, a second ring body is fixedly connected to the top of the carriage, and three levers are hinged to the bottom of the second ring body. The upper surface of the levers abuts against the surface of the side shaft, and a latch is provided on the side of the second ring body opposite to the connection of the levers.

[0009] Preferably, the top of the dilution tank is provided with a pulley assembly that is connected to the tripod for transmission. The end of the pulley assembly away from the tripod is engaged with a ring body three by gears. Three bent rods are fixedly connected to the outer side of the ring body three, and the bent rods abut against the lower surface of the lever.

[0010] Preferably, a filter frame is fixedly connected to the top of the inner wall of the dispensing tank, a servo motor is provided on the side of the filter frame, and a wave-shaped component is arranged in a ring on the inner wall of the filter frame.

[0011] Preferably, a filter basket is provided in the middle of the filter frame, and a rotating mounting component is provided on the top of the filter basket. The rotating mounting component is rotatably connected to the top of the filter frame and is driven by a servo motor.

[0012] Preferably, the bottom of the rotating mounting component is symmetrical and hinged with a telescopic rod, the end of the telescopic rod away from the rotating mounting component is hinged to the filter basket, and one of the telescopic rods is fitted with a spring.

[0013] Preferably, a pressure shaft is fixedly connected to the bottom of one of the telescopic rods on which the spring is installed, and the pressure shaft abuts against the upper surface of the corrugated member.

[0014] Preferably, a method for using a dilution and defoaming device in the processing of anti-corrosion coatings includes the following steps:

[0015] S1: Inject the anti-corrosion coating raw material into the dilution tank, add a quantitative amount of diluent through the top feed port, empty the dispensing tank and prepare to receive the processed coating, turn on the drive motor, the output shaft drives the main gear to rotate clockwise, the three auxiliary gears on the outer ring of the main gear rotate counterclockwise synchronously under the action of the internal gear ring, forming a planetary gear structure, and revolve around the main gear at the same time, the central stirring shaft rotates coaxially with the main gear, and performs preliminary mixing in the central area of ​​the coating, the outer ring stirring shaft drives the inner sleeve to rotate through the auxiliary gear, the outer ring stirring shaft moves in a circle along the guide groove, shearing and dispersing the coating edge area, so that the viscosity of the viscous coating at the edge is gradually reduced, the outer ring stirring shaft is in a low position, forming a low-speed large-range stirring state, the coating and diluent are initially mixed under the synergistic action of the inner and outer stirring shafts, and the viscosity of the coating gradually decreases;

[0016] S2: The pulley assembly drives the ring body to rotate via the tripod transmission, and the bent rod rotates synchronously. During the process, the push bar is pushed to make it flip upward around the second hinge point of the ring body. The upper surface of the push bar pushes the side shaft to slide upward along the slide. The side shaft drives the first ring body and the lifting rod to rise. The outer ring moves upward synchronously, pulling the outer ring stirring shaft to slide upward along the guide groove to the top of the inner sleeve. The side shaft is located in the bayonet, so that the outer ring stirring shaft is pulled out of the paint. After the bent rod passes the push bar, the push bar automatically drops down, so that the first ring body drives the outer ring stirring shaft to re-enter the paint for stirring. At this time, the drive motor speed increases, and the main gear drives the outer ring stirring shaft to rotate at a higher linear speed through the secondary gear, which performs high-intensity shearing on the paint and breaks the bubbles on the paint surface. The central stirring shaft rotates synchronously at high speed to form convection and ensure the uniformity of defoaming.

[0017] S3: Start the metering pump to draw the diluted and defoamed paint from the bottom of the dilution tank and quantitatively deliver it to the dispensing tank through the output pipe. When the paint enters the dispensing tank, it first falls into the filter basket inside the filter frame. The servo motor drives the rotating mounting component to rotate the filter basket at high speed. Under the action of centrifugal force, the paint flows towards the edge of the filter basket. The pressure shaft at the bottom of the telescopic rod slides on the corrugated part, causing the telescopic rod to extend and retract periodically, causing the filter basket to rotate and swing. During the rotation, the bottom side area comes into contact with the upper surface of the filter frame to crush the foam and further break up the residual bubbles on the surface of the paint. The paint that has been defoamed passes through the mesh of the filter basket, removing unbroken micro bubbles and particulate impurities, and finally falls into the dispensing tank for storage.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In this invention, the outer ring stirring shaft is driven by the secondary gear to make circumferential motion along the guide groove, which works in conjunction with the central stirring shaft to form synchronous stirring of the center and edge areas of the coating, thereby improving the uneven viscosity distribution. When the outer ring stirring shaft is running at a low position, it can achieve large-scale stirring at low speed, so that the coating and diluent are mixed evenly, improving the dilution efficiency and reducing the risk of uneven coating dilution.

[0020] 2. In this invention, the outer ring stirring shaft is intermittently raised and lowered by a belt pulley group and a bent rod pushing a lever. When it is raised, it is removed from the coating to reduce unnecessary stirring. When it is lowered, it is accelerated in conjunction with the drive motor to perform high-intensity shearing on the coating at a higher linear speed, accurately breaking surface bubbles and improving defoaming efficiency.

[0021] 3. In this invention, the outer ring stirring shaft is intermittently raised and lowered by a belt pulley drive and a bent rod pushing the lever. When it rises, it is separated from the coating to reduce unnecessary stirring. When it falls, it is accelerated in conjunction with the drive motor to perform high-intensity shearing on the coating at a higher linear speed, accurately breaking surface bubbles and improving defoaming efficiency.

When the paint enters the dispensing tank (5), it first falls into the filter basket (804) in the filter frame (801). The servo motor (802) drives the rotating mounting part (805) to drive the filter basket (804) to rotate at high speed. Under the action of centrifugal force, the paint flows to the edge of the filter basket (804). The pressure shaft (808) at the bottom of the telescopic rod (806) slides on the wave part (803), causing the telescopic rod (806) to periodically extend and retract, causing the filter basket (804) to rotate and swing. During the rotation, the bottom side area is in contact with the upper surface of the filter frame (801) to crush the foam and further break the residual bubbles on the surface of the paint. The paint that has been defoamed passes through the mesh of the filter basket (804) to remove unbroken micro bubbles and particulate impurities, and finally falls into the dispensing tank (5) for storage.
