Abstract
Description
Technical Field
[0001] This utility model relates to the field of laundry detergent production technology, and in particular to a defoaming device for laundry detergent production. Background Technology
[0002] In the industrial production of laundry detergent, efficient mixing is crucial for ensuring product quality and performance. Mixing ensures that various surfactants, additives, fragrances, and other raw materials are thoroughly and evenly combined, giving the detergent excellent cleaning, thickening, and stabilizing properties. However, during mixing, a significant amount of air inevitably gets mixed into the detergent's raw material system, resulting in excessive foam. This foam not only affects mixing efficiency and uniformity but can also lead to unstable operation of production equipment, and even cause raw material waste and environmental pollution.
[0003] Currently, most defoaming devices for laundry detergent on the market use traditional agitators. While this method achieves a certain degree of mixing, the high-speed rotation of the agitator violently agitates the liquid, introducing a large amount of air and generating excessive foam. To eliminate this foam, chemical defoamers are usually added. However, the use of chemical defoamers not only increases production costs but may also negatively impact the quality and environmental performance of the laundry detergent. Furthermore, some defoaming devices attempt to reduce foam generation by altering the agitation method or structure, but these often struggle to effectively reduce foam generation while maintaining good agitation, resulting in an unsatisfactory balance between agitation and defoaming effects.
[0004] Therefore, developing a defoaming device for laundry detergent production that can achieve efficient mixing, significantly reduce foam generation, and does not rely on large amounts of chemical defoamers has become an urgent problem to be solved in the current laundry detergent production field.

[0026] It should be noted that all components in the technical solution of this application require necessary additional facilities for water supply, oil supply, power supply, and gas supply for driving and / or control.

[0027] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Depend on Figure 1-6 The defoaming device for laundry detergent production shown includes two stirring units, with several stirring tubes 1 fixedly connected and communicating between the two stirring units; each stirring unit includes a pressure tank 2, a drive assembly fixedly installed on the top surface of the pressure tank 2, and a piston plate 3 driven by the drive assembly, the piston plate 3 being slidably connected to the pressure tank 2 in a sealed manner; several sprayers for spraying hot air are fixedly connected to the drive assembly; an installation hole is opened on the top surface of the piston plate 3, and a viewing window 4 is fixedly installed in the installation hole for observing the inner cavity of the pressure tank 2; the cavity between the piston plate 3 and the bottom surface of the inner cavity of the pressure tank 2 and the stirring tubes 1 are used to hold the raw materials for laundry detergent production; an agitator for stirring the raw materials for laundry detergent production is provided in the inner cavity of the stirring tubes 1.
[0029] Furthermore, the bottom outer side of the pressure tank 2 is fixedly connected to and connected to a feed pipe 19 for the inlet and outlet of the raw materials for the production of laundry detergent, and a valve is connected in series on the feed pipe 19 to facilitate the addition and extraction of raw materials into the pressure tank 2.
[0030] Furthermore, the stirring tube 1 is located at the bottom outer side of the pressure tank 2, utilizing the principle of communicating vessels to ensure complete filling of the raw materials for laundry detergent production within the stirring tube 1. Additionally, the top surface of the piston plate 3 is fixedly connected to and connected to an exhaust valve 18, which can expel air generated inside the pressure tank 2 during the operation of this device, reducing foam generation during the stirring process of the raw materials for laundry detergent production.
[0031] Further optimizing the design, the piston plate 3 has an installation groove on its periphery, and a gap is formed between the circumferential side of the piston plate 3 and the inner wall of the pressure tank 2. A rubber stopper ring 5 is embedded in the installation groove, and the rubber stopper ring 5 is slidably connected to the inner wall of the pressure tank 2. The rubber stopper ring 5 and the piston plate 3 combine to form a piston, facilitating the pushing of the raw material filling the inner cavity of the pressure tank 2. Several grooves 6 are formed on the top edge of the piston plate 3 about the center of the piston plate 3; a push rod 7 is symmetrically fixedly connected to the top surface of the rubber stopper ring 5, and the push rod 7 is set in the groove 6; a connecting rod 8 is fixedly connected to the top of the push rod 7, and an electric cylinder 9 is fixedly connected between the two connecting rods 8. The electric cylinder 9 is installed through the drive assembly. The electric cylinder 9 can pull the connecting rods 8 fixedly connected at both ends of the electric cylinder 9 to pull the rubber stopper ring 5 away from the inner wall of the pressure tank 2 and create a gap. Then, after foam is generated during the stirring of the raw materials for the production of laundry detergent, the piston plate 3 is pushed to squeeze the foam to the top surface of the piston plate 3.
[0032] Further optimization of the scheme: the drive component includes a bracket 10, the bottom of the bracket 10 is fixedly connected to the pressure tank 2, the top of the bracket 10 is fixedly connected to a hydraulic cylinder 11, the piston rod of the hydraulic cylinder 11 is fixedly connected to the piston plate 3, the bracket 10 is fixedly connected to the sprayer, the hydraulic cylinder 11 can achieve a large thrust to drive the piston plate 3 to squeeze and stir the raw materials for the production of laundry detergent.
[0033] Further optimization of the design: the agitator includes several parallel cutting plates 12, all of which are divided into several groups. The two ends of the cutting plates 12 are fixedly connected to the inner wall of the agitation tube 1. When the raw materials for producing laundry detergent enter the agitation tube 1 under the push of the piston plate 3, they will continuously collide and cut with the cutting plates 12 during the flow process. This can cut and mix the raw materials for producing laundry detergent that are not mixed evenly, reducing the foam formed by the bubbles generated by the high-speed agitation of traditional agitators.
[0034] Further optimization of the design: the agitator includes a rotating shaft 13, one end of which is fixedly connected to a connecting plate 14, and both ends of the connecting plate 14 are fixedly connected to the inner wall of the agitation tube 1; the rotating shaft 13 is rotatably connected to a paddle 15, which is driven by the flow of the raw materials for producing laundry detergent, and the rotation of the paddle 15 can drive the raw materials for producing laundry detergent to rotate and agitate, thereby improving the mixing efficiency.
[0035] The design is further optimized so that the sprayer includes a fan 16 and a heating wire 17. The heating wire 17 is fixedly installed at the air outlet of the fan 16, and the fan 16 is fixedly connected to the bracket 10. The heating wire 17 is connected to an external driving power supply.
[0036] The design is further optimized by inverting a bevel on the top edge of the piston plate 3, which allows water to be injected from the top opening of the pressure tank 2 after the blower 16 breaks the foam. The water dissolves the residue after the foam is broken and is then reintroduced into the laundry detergent through the opening of the rubber stopper ring 5.
[0037] Further optimization of the design involves making window 4 transparent fiberglass or tempered glass, which facilitates observation of the stirring state inside pressure tank 2 and helps to promptly dissipate excess foam generated during production.
[0038] The working process of this embodiment is as follows:
[0039] This invention utilizes a hydraulic cylinder 11 to push a piston plate 3 to squeeze the raw materials for producing laundry detergent inside the pressure tank 2. At the same time, the hydraulic cylinder 11 of the stirring unit on the other side synchronously pulls the piston plate 3 upward, which facilitates the flow of the raw materials for producing laundry detergent from one pressure tank 2 through the stirring tube 1 to another pressure tank 2.
[0040] This device can reduce the rate of foam generation. However, when excessive foam is unavoidable, the piston plate 3 is squeezed by the hydraulic cylinder 11, and the electric cylinder 9 can pull open the rubber stopper ring 5 to create pores, thus extruding the foam onto the top surface of the piston plate 3. The fan 16 and heating wire 17 are started, and the heat generated by the heating wire 17 driven by air is used to vaporize and break up the overflowing foam. After breaking up, clean water is injected from the top opening of the pressure tank 2. The clean water dissolves the residue after the foam is broken up and is reintroduced into the laundry detergent through the pores pulled out by the rubber stopper ring 5 for remixing.
[0041] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
