Abstract
Description
A defoaming device for an antibacterial coating filling machine Technical Field
[0001] This utility model relates to the field of defoaming technology for antibacterial coating filling machines, and in particular to a defoaming device for antibacterial coating filling machines. Background Technology
[0002] Antibacterial coatings require the addition of antibacterial agents, such as silver ions and organic antibacterial agents, during production. These components are prone to foaming during high-speed mixing or filling. During the filling process, the coating is directly poured into the packaging container through the filling machine without defoaming treatment. The large number of air bubbles in the coating significantly affects the appearance of the coating film and its related performance during use. Therefore, a defoaming device is needed to defoam antibacterial coatings. For example, Chinese utility model patent CN208716813U describes a defoaming device for a coating filling machine. The proposed defoaming device features a buffer bend and a defoaming bend with their bottom openings facing opposite directions. The bottom openings can respectively conform to the inner wall of the defoaming bend and the packaging container, effectively buffering the coating and preventing air bubble formation. The defoaming bend is positioned by moving up and down using a cylinder. The device is simple to operate, suitable for different types of packaging containers, and is movable, making installation, disassembly, and cleaning convenient.
[0003] The above devices still have some problems in use. While they can reduce the bubbles generated when the coating is directly poured into the packaging barrel by the filling machine after preparation, they cannot eliminate the bubbles generated during the coating preparation process. Therefore, they cannot effectively defoam the coating. Summary of the Invention
[0004] To address the aforementioned technical problems, this utility model provides a defoaming device for an antibacterial coating filling machine. The device comprises a temporary storage structure, a rotary defoaming structure, a negative pressure defoaming structure, and a filling structure. The rotary defoaming structure is installed below the temporary storage structure, the negative pressure defoaming structure is installed on the side of the rotary defoaming structure, and the filling structure is installed below the negative pressure defoaming structure.
[0005] The temporary storage structure consists of an inlet pipe, a storage tank, a conveying pipe A, and a discharge valve. The inlet pipe is installed above the storage tank, the conveying pipe A is installed below the storage tank, and the discharge valve is installed on the outside of the conveying pipe A.
[0006] The rotary defoaming structure consists of a defoaming tank, a motor housing, spiral blades, a defoaming plate, a plate frame, and a rotating shaft. One end of the conveying pipe A is connected to the defoaming tank. The motor housing is installed above the defoaming tank, and the rotating shaft is installed below the motor housing. The rotating shaft is connected to a motor inside the motor housing. Spiral blades are installed on the outside of the rotating shaft. A plate frame is installed at the bottom inside the defoaming tank, and the defoaming plate is installed on top of the plate frame.
[0007] The negative pressure defoaming structure consists of a conveying pipe B and a negative pressure defoaming box. The conveying pipe B is installed on one side below the defoaming tank, and one end of the conveying pipe B is connected to the negative pressure defoaming box.
[0008] The filling structure consists of a discharge pipe, a discharge valve, and a filling pipe. The discharge pipe is installed below the negative pressure defoaming box, the discharge valve is installed on the outside of the discharge pipe, and the filling pipe is installed below the discharge pipe.
[0009] The beneficial effects of this utility model are:
[0010] This utility model discloses a defoaming device for an antibacterial coating filling machine. During operation, the antibacterial coating to be filled flows into a storage tank via an inlet pipe. The coating in the storage tank then flows through a conveying pipe A, with a discharge valve controlling the flow rate. The coating enters a defoaming tank, where a motor in the motor housing starts, rotating the shaft and driving spiral blades to defoam the coating. The coating then passes through a defoaming plate and flows through a conveying pipe B into a negative pressure defoaming chamber. After negative pressure defoaming, the coating flows out through a discharge pipe and is then filled through a filling pipe, with the discharge valve limiting the filling flow rate. This device includes a storage tank for initial static defoaming, followed by further defoaming via the spiral blades in the defoaming tank. The coating then passes through a defoaming plate with micropores on its surface, which break up and defoam the air bubbles. Finally, the coating enters the negative pressure defoaming chamber, where negative pressure removes any remaining air bubbles before filling. This method effectively reduces the amount of air bubbles generated during the coating production process. Attached Figure Description
