Description

Technical Field

[0001] The present invention relates to the technical field of laundry liquid production equipment, in particular to a defoaming device for laundry liquid production. Background Art

[0002] As people's living standards continue to improve, the demand for laundry detergent is also growing. During the production process, laundry detergent contains a large amount of surfactants and other ingredients, which easily generate a large amount of foam during the mixing and conveying process. This foam not only affects production efficiency but can also cause laundry detergent to overflow, resulting in waste and environmental pollution.

[0003] Currently, two common defoaming methods are chemical and physical. Chemical defoaming eliminates foam by adding defoaming agents, but the use of defoaming agents can affect the performance of the laundry detergent and is expensive. Physical defoaming primarily uses mechanical methods, such as defoamers, stirring, or vibrations, to eliminate foam. However, existing defoaming devices suffer from unsatisfactory defoaming effects, complex structures, and inconvenient operation. Summary of the Invention

[0004] The purpose of the present invention is to provide a defoaming device for laundry liquid production, which can directly physically puncture and defoam the foam during the flow of the laundry liquid, does not rely on chemical defoaming agents, avoids the influence of defoaming agents on the performance of the laundry liquid, and reduces costs.

[0007] Furthermore, the stirring mechanism includes a rotating shaft arranged in the tank body, a driving motor for driving the rotating shaft to rotate is installed on the top of the tank body, and a plurality of stirring blades are fixedly installed on the rotating shaft.

[0008] Furthermore, the stirring blade is arranged obliquely on the rotating shaft.

[0009] Furthermore, an air extraction port is provided on the top of the tank body, and the air extraction port is connected to an air extraction pump.

[0020] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the embodiments and the accompanying drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, a defoaming device for laundry liquid production includes a tank body 1, a liquid inlet pipe 2 is provided on the top of the tank body 1, a liquid outlet pipe 3 is provided at the bottom of the tank body 1, a stirring mechanism is provided in the tank body 1, a defoaming plate 4 is provided in the side wall of the tank body 1, and a plurality of defoaming needles 5 are provided on the outer wall of the defoaming plate 4.

[0022] The stirring mechanism includes a rotating shaft 6 disposed in the tank body 1 . A driving motor 7 for driving the rotating shaft 6 to rotate is installed on the top of the tank body 1 . A plurality of stirring blades 8 are fixedly mounted on the rotating shaft 6 .

[0023] The stirring blade 8 is tiltedly arranged on the rotating shaft 6; the tilted arrangement of the stirring blade 8 can increase the shear force on the foam, further improve the foam breaking effect, and make the foam easier to be processed by the subsequent defoaming mechanism.

[0024] An exhaust port 9 is provided on the top of the tank body 1, and the exhaust port 9 is connected to an exhaust pump; when connected to the exhaust pump, the gas inside the tank body 1 can be extracted, thereby reducing the air pressure inside the tank body 1, causing the foam to expand and burst, accelerating the elimination of the foam, and improving the defoaming effect.

[0025] An air pressure sensor 10 is installed on the inside of the tank body 1; the setting of the air pressure sensor 10 can monitor the air pressure inside the tank body 1 in real time, making it convenient for the operator to adjust the working state of the air pump according to the air pressure conditions, ensuring the defoaming effect while avoiding excessive air extraction from having adverse effects on the performance of the laundry detergent.

[0026] There are multiple groups of defoaming plates 4, which are staggered in the tank body 1; the staggered arrangement of multiple groups of defoaming plates 4 increases the probability of contact between the foam and the defoaming plates 4, so that the foam needs to pass through multiple defoaming plates 4 during the flow process, thereby improving the thoroughness of defoaming.

[0027] The defoaming plate 4 is provided with a plurality of through holes 401 ; the defoaming plate 4 is provided with a plurality of through holes 401 so that the laundry liquid can flow more smoothly and reduce the flow resistance, while also increasing the contact opportunity between the foam and the defoaming plate 4 and improving the defoaming efficiency.

[0028] An electric heating plate 11 is embedded in the inner wall of the tank body 1; the setting of the electric heating plate 11 can heat the laundry liquid, reduce the viscosity of the laundry liquid, make the liquid in the foam film flow more easily, accelerate the drainage of the liquid film, thereby destroying the stability of the foam and further improving the defoaming effect.

[0029] Working principle:

[0030] Laundry liquid enters the tank 1 through the liquid inlet pipe 3. Driven by the drive motor 7, the rotating shaft 6 in the stirring mechanism rotates, causing the stirring blades 8 to stir the laundry liquid. This not only ensures a more even mixing of the ingredients in the laundry liquid, but also shears and breaks up the foam. Defoaming plates 4 and defoaming needles 401 in the sidewalls of the tank 1 physically puncture and defoam the foam. Multiple sets of staggered defoaming plates 4 increase the probability of contact between the foam and the defoaming needles 401. An air extraction port 9 is connected to an air pump to reduce the air pressure in the tank 1, causing the foam to expand and burst. An air pressure sensor 10 monitors the air pressure in the tank 1 in real time. An electric heating plate 11 heats the laundry liquid, reducing its viscosity and accelerating the collapse of the foam. Finally, the defoamed laundry liquid flows out of the liquid outlet pipe 3.

[0031] The present invention adopts a physical defoaming method and does not use chemical defoaming agents, thereby avoiding the impact on the performance of the laundry detergent and reducing the cost; the stirring mechanism, the defoaming plate 4, the air pump and the heating plate 11 work together to improve the defoaming efficiency and thoroughness; the structure is compact, does not take up additional space, and is easy to install and use; the cooperation of multiple groups of staggered defoaming plates 4 and defoaming needles 5 and the heating plate 11 makes the defoaming effect more significant, thereby improving the production quality and efficiency of the laundry detergent.
