Description

Technical Field

[0001] This utility model belongs to the field of coating technology, and in particular relates to an ultrasonic defoaming device. Background Technology

[0002] During the coating process, foam can be generated due to factors such as rapid solvent evaporation and excessive air introduction during stirring. This foam increases the viscosity of the coating liquid, making coating more difficult and affecting the use of spraying, roller coating, and other coating methods. It also leads to uneven coating, impacting coating quality and production efficiency. Therefore, in practical applications, it is necessary to select a suitable defoaming method to improve the quality of the coated product. Currently, there are two defoaming methods: chemical defoaming (adding defoaming agents) and physical defoaming (using mechanical defoamers), or a combination of both. When using a rod-shaped ultrasonic defoamer, it is common to vertically insert the ultrasonic defoamer into the slurry. However, in actual production, the liquid level in the slurry tank is low, and vertical insertion makes it difficult to control the ultrasonic defoamer to be fully submerged in the slurry tank. Furthermore, with long-term use, slurry residue forms a dense coating layer on the transducer surface, requiring daily cleaning with a special solvent. The existing installation method also presents the problem of inconvenient installation and disassembly of the ultrasonic defoamer. Summary of the Invention

[0003] The purpose of this invention is to provide an ultrasonic defoaming device that, by controlling the ultrasonic defoamer to be installed at an angle in the slurry tank, ensures that the effective working section is 100% submerged below the liquid surface, thus solving the problem that existing vertically inserted ultrasonic defoamers cannot be easily controlled to be mostly submerged in the slurry tank.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an ultrasonic defoaming device, comprising a slurry tank and a coating roller and a pressure roller spaced apart. The coating roller and the pressure roller are both located above the slurry tank, and the bottom of the coating roller is submerged below the liquid surface of the slurry tank. It also includes an inclined ultrasonic defoamer, one end of which is submerged below the liquid surface and the other end is electrically connected to a power source, facilitating control that the effective working section of the ultrasonic defoamer is 100% submerged below the liquid surface. The ultrasonic defoamer has a rod-shaped structure, and the ultrasonic cavitation effect simultaneously optimizes the slurry leveling.

[0005] Furthermore, it also includes an installation assembly for mounting the ultrasonic defoamer; the installation assembly includes a mounting bracket fixed to the side wall of the slurry tank, a connecting column A connected to one side of the mounting bracket, a rotatable connecting arm at the end of the connecting column A, and an installation head mounted at the end of the connecting arm, the ultrasonic defoamer mounted on the installation head; an arc-shaped plate is also connected to one side of the mounting bracket via a connecting column B, the arc-shaped plate having an arc-shaped opening; a protrusion is provided on the swing arm, a stud passing through the arc-shaped opening is connected to the protrusion, and a disc nut is threadedly connected to the end of the stud, abutting against the arc-shaped plate, facilitating the insertion of the ultrasonic defoamer below the liquid surface as needed, or the removal of the ultrasonic defoamer from below the liquid surface for disassembly and cleaning as needed.

[0006] Furthermore, the fixing frame includes a U-shaped rod, with two L-shaped locking blocks connected to both ends of the U-shaped rod. The L-shaped locking blocks are locked on the side wall of the slurry tank, and the threaded end of the L-shaped locking block abuts against the locking bolt on the outer side wall of the slurry tank. The fixing frame facilitates the installation and disassembly of the ultrasonic defoamer without changing the structure of the slurry tank.

[0007] Furthermore, the mounting head has a through hole for mounting the ultrasonic defoamer; one side of the mounting head is provided with a rubber sleeve that is fitted over the outside of the ultrasonic defoamer. The rubber sleeve facilitates the removal of most of the slurry adhering to the ultrasonic defoamer when it is pulled out.

[0008] This utility model has the following beneficial effects: This invention controls the ultrasonic defoamer to be installed at an angle in the slurry tank, ensuring that the effective working section is 100% submerged below the liquid surface. At the same time, the installation components, including a fixing frame and a swing arm, make it convenient to insert the ultrasonic defoamer below the liquid surface or remove it from the liquid surface for disassembly and cleaning as needed.
