Description

Technical Field

[0001] This utility model relates to the field of defoaming device technology, specifically a defoaming device for water-based paint production. Background Technology

[0002] Defoaming in water-based paint production refers to the crucial step of eliminating or suppressing bubble formation during the manufacturing process of water-based coatings to ensure product quality and efficiency. Foam is mainly formed by gases introduced by physical or chemical factors such as stirring, chemical reactions, and temperature changes. At the same time, surface-active substances reduce the surface tension of the liquid and stabilize the bubbles, thereby affecting the uniformity, appearance, and application effect of the coating. Defoaming devices in water-based paint production are physical devices specifically designed to eliminate bubbles during the manufacturing process of water-based coatings. They mainly use mechanical force, vacuum, or centrifugal action to disrupt foam stability, ensuring coating quality and production efficiency.

[0003] For example, publication number CN221045517U discloses a defoaming device for water-based paint production, including a supporting base plate located below a defoaming plate. The surface of the defoaming plate is fixedly connected to the inner surface of the defoaming tank. A support frame is fixedly connected to the upper surface of the defoaming tank, and a motor is mounted on the surface of the support frame. A rotating shaft is fixedly connected to the output end of the motor. A stirring rod is fixedly connected to the surface of the rotating shaft, and a side wall brush is fixedly connected to the surface of the stirring rod. A cleaning brush is fixedly connected to the lower end surface of the rotating shaft. A supporting leg is fixedly connected to the lower surface of the supporting base plate, and a defoaming tank is fixedly connected to the upper surface of the supporting base plate. An inlet pipe is fixedly connected to the upper end surface of the defoaming tank. This utility model, by providing the side wall brush and the cleaning brush, facilitates the cleaning of the defoaming tank, increasing its practicality during use.

[0004] However, in actual use, the stirring and defoaming components of the defoaming device in water-based paint production have certain limitations. During the defoaming process in water-based paint production, the liquid level changes dynamically due to the bursting of bubbles, and the fixed defoaming plate will affect the defoaming effect. At the same time, the stirring brush will deform after long-term use, further weakening the cleaning power and making it difficult to improve the working efficiency and performance of the stirring and defoaming components. Based on this, a defoaming device for water-based paint production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a defoaming device for water-based paint production, which has the advantages of tracking liquid level for defoaming and self-adjusting brush cleaning intensity. It solves the problems that the liquid level height will change dynamically due to the bursting of bubbles, and that a fixed defoaming plate will affect the defoaming effect. At the same time, the stirring brush will deform after long-term use, further weakening the cleaning intensity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a defoaming device for water-based paint production, comprising a defoaming tank, a drive motor fixedly installed at the upper end of the defoaming tank, a drive shaft fixedly installed inside the defoaming tank at the output end of the drive motor, a cleaning frame fixedly installed on the surface of the drive shaft, a stirring rod fixedly installed inside the cleaning frame at the surface of the drive shaft, a pressure regulating component provided on the cleaning frame, a cleaning brush provided on the pressure regulating component, electric telescopic rods fixedly installed on both the left and right sides of the upper end of the defoaming tank, a defoaming plate fixedly installed inside the defoaming tank at the output end of the electric telescopic rod, a liquid level detection module fixedly installed inside the defoaming plate, a drain pipe fixedly connected to the lower side of the surface of the defoaming tank, and a drain port assembly provided at the right end of the drain pipe.

[0007] Furthermore, the drive motor is used to drive the transmission shaft to rotate. The output end of the drive motor is rotatably connected to the defoaming tank, and the lower end of the transmission shaft is rotatably connected to the defoaming tank. The stirring rods are evenly distributed and are fixedly connected to the cleaning frame.

[0008] Furthermore, the pressure regulating assembly includes a sleeve, an adjusting spring is fixedly installed inside the sleeve, a movable block is fixedly installed on the adjusting spring, and a movable rod is fixedly installed on the movable block.

[0009] Furthermore, the sleeves are evenly spaced and fixedly connected to the cleaning frame. The surfaces of the movable block and the movable rod are slidably connected to the sleeves. The end of the movable rod away from the movable block extends to the outside of the sleeve and is fixedly connected to the cleaning brush.

[0010] Furthermore, the electric telescopic rod is used to move the defoaming plate up and down. The output end of the electric telescopic rod is slidably connected to the defoaming tank, the liquid level detection module is electrically connected to the electric telescopic rod, and the surface of the drive shaft is slidably connected to the defoaming plate.

[0011] Furthermore, an electrically controlled valve is installed on the drain pipe, a one-way pipe is fixedly connected to the upper side of the surface of the defoaming tank, a one-way valve is installed on the one-way pipe, a connecting chamber is fixedly connected to the left end of the one-way pipe, and an inlet pipe and a feeding pipe are fixedly connected to the upper end of the connecting chamber.

[0012] Furthermore, the drain port assembly includes a connecting sleeve, with a drain filter port fixedly connected to the right end of the connecting sleeve. The connecting sleeve is detachably connected to the drain pipe, and a filter screen is installed inside the drain filter port.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: This defoaming device for water-based paint production uses cones on the defoaming plate to puncture the bubble film. Combined with a liquid level detection module, it monitors the liquid level in real time, allowing for easy adjustment of the defoaming plate's position to ensure it remains at the appropriate defoaming height. This avoids incomplete defoaming due to manual intervention and guarantees optimal defoaming results. A pressure regulating unit connects to a cleaning brush for cleaning the defoaming tank. An adjusting spring adjusts the position of the cleaning brush, ensuring the pressure on the brush and the inner surface of the defoaming tank remains within a suitable range. This allows the cleaning brush to continue operating for a longer period even after deformation, maintaining its cleaning effectiveness and extending its lifespan. Attached Figure Description

A pressure regulating component is provided on the cleaning frame 4. A cleaning brush 6 is provided on the pressure regulating component. Electric telescopic rods 7 are fixedly installed on both the left and right sides of the upper end of the defoaming tank 1. A defoaming plate 8 is fixedly installed inside the defoaming tank 1 at the output end of the electric telescopic rod 7. A liquid level detection module 9 is fixedly installed inside the defoaming plate 8. A drain pipe 10 is fixedly connected to the lower side of the surface of the defoaming tank 1. A drain port assembly is provided at the right end of the drain pipe 10.

[0018] In this embodiment, the bubble film is punctured by the cone of the defoaming plate 8, and the liquid level is monitored in real time by the liquid level detection module 9. This facilitates the adjustment of the position of the defoaming plate 8 so that it is always at a suitable defoaming height, avoiding incomplete defoaming caused by manual intervention and ensuring the best defoaming effect. The defoaming plate 8 and the defoaming tank 1 can be equipped with structures with venting function (the defoaming tank can be equipped with a vent, and a filter screen or other structure for splash prevention can be installed in the vent to improve the venting function).

[0019] Please see Figures 1-5 In this embodiment, the drive motor 2 is used to drive the transmission shaft 3 to rotate. The output end of the drive motor 2 is rotatably connected to the defoaming tank 1. The lower end of the transmission shaft 3 is rotatably connected to the defoaming tank 1. The stirring rods 5 are evenly distributed and are fixedly connected to the cleaning frame 4. The pressure regulating component includes a sleeve 11. An adjusting spring 12 is fixedly installed inside the sleeve 11. A movable block 13 is fixedly installed on the adjusting spring 12. A movable rod 14 is fixedly installed on the movable block 13. The sleeves 11 are evenly distributed and are fixedly connected to the cleaning frame 4. The surfaces of the movable block 13 and the movable rod 14 are slidably connected to the sleeve 11. The end of the movable rod 14 away from the movable block 13 extends to the outside of the sleeve 11 and is fixedly connected to the cleaning brush 6. The electric telescopic rod 7 is used to drive the defoaming plate 8 to move up and down. The output end of the electric telescopic rod 7 is slidably connected to the defoaming tank 1. The liquid level detection module 9 is electrically connected to the electric telescopic rod 7. The surface of the transmission shaft 3 is slidably connected to the defoaming plate 8.

[0020] It should be noted that the drain pipe 10 can be used for material collection, the electric control valve can be used to control the drain pipe 10, and the drain filter port 18 can be used for collection and filtration simultaneously (the drain port assembly can be flexibly disassembled and installed, making it convenient to clean the filter screen inside the drain filter port 18 or to replace it. The filter screen can be selected according to the actual situation, and the filtration structure can be set. This is a key measure to prevent impurities from entering the finished product and to ensure the purity of the paint). After collection, clean water can be injected into the defoaming tank 1, and the rotating cleaning brush 6 can be used for cleaning (the edges and corners of the cleaning brush 6 can be adjusted by adjusting the brush structure to fill some gaps and dead corners. For example, the edges and corners of the brush with an inclined structure can be used to fit the lower corner space of the tank to ensure more comprehensive cleaning). The sleeve 11, movable block 13 and movable rod 14 are used to restrict the movement and direction of force. The cleaning brush 6 is driven to fit into the inside of the defoaming tank 1 by adjusting the spring 12 (the adjusting spring 12 is an adjusting spring with appropriate elasticity according to the cleaning needs), and appropriate squeezing force is ensured within a certain range.

[0021] Please see Figures 1-4 In this embodiment, an electrically controlled valve is provided on the drain pipe 10, a one-way pipe 15 is fixedly connected to the upper side of the surface of the defoaming tank 1, a one-way valve is provided on the one-way pipe 15, a connecting chamber box 16 is fixedly connected to the left end of the one-way pipe 15, an inlet pipe and a feeding pipe are fixedly connected to the upper end of the connecting chamber box 16, the drain port assembly includes a connecting sleeve 17, a drain filter port 18 is fixedly connected to the right end of the connecting sleeve 17, the connecting sleeve 17 is detachably connected to the drain pipe 10, and a filter screen is provided inside the drain filter port 18.

[0022] It should be noted that the two ports connecting the chamber 16 can be used for adding materials and liquids (a one-way valve is installed on the one-way pipe 15 to prevent material backflow), allowing the material to enter the defoaming tank 1. The drive motor 2 can drive the transmission shaft 3 to rotate (the drive motor 2 can also be replaced by a hydraulic motor or other drive equipment). The stirring rod 5 can stir the water-based paint production materials (the stirring rod 5 is connected to the cleaning frame 4 to improve the strength of the component). The liquid level detection module 9 can monitor the liquid level in real time (a radar sensor or similar detection module can detect sub-millimeter level fluctuations and transmit data to the equipment terminal in real time. The terminal can also control other drive components according to the program). The electric telescopic rod 7 can adjust the position of the defoaming plate 8 (the electric telescopic rod 7 can also be replaced by other existing equipment, such as a hydraulic cylinder structure, to achieve the effect of outputting power in the axial direction. The synchronous operation of the two electric telescopic rods 7 is an existing technology, which is synchronously controlled by the equipment terminal), so that it is always at a suitable defoaming height (the movement space of the defoaming plate 8 is limited within a certain range to ensure the defoaming effect and avoid interference with other components). The defoaming plate 8 punctures the bubble film, completing the efficient defoaming work.

[0023] The working principle of the above embodiments is as follows: In use, the material and liquid are added through the two ports of the connecting chamber 16, allowing it to enter the defoaming tank 1. The drive motor 2 drives the transmission shaft 3 to rotate, causing the stirring rod 5 to stir the water-based paint production material. At the same time, the liquid level detection module 9 monitors the liquid level in real time, and the electric telescopic rod 7 is used to adjust the position of the defoaming plate 8 according to the liquid level, so that it is always at a suitable defoaming height. The defoaming plate 8 punctures the bubble film, completing the efficient defoaming work. After processing, the material is discharged and collected through the drain pipe 10, and collected and filtered simultaneously with the drain filter port 18. After collection, clean water is injected into the defoaming tank 1, and the rotating cleaning brush 6 is used for cleaning. The sleeve 11, movable block 13 and movable rod 14 restrict the movement and direction of force. The adjusting spring 12 drives the cleaning brush 6 to fit into the inside of the defoaming tank 1, ensuring a suitable squeezing force within a certain range.

[0024] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.
