Description

Technical Field

[0001] This application belongs to the field of wastewater treatment technology, and in particular relates to a foam treatment device. Background Technology

[0002] In the milk powder production process, cleaning the production equipment with alkaline liquid is a common method of decontamination and disinfection to ensure that the hygiene level of the production equipment meets the production requirements.

[0003] For environmental protection and energy conservation purposes, the alkaline liquid used to clean the equipment needs to be recycled. However, alkaline foam with large bubbles will form in the alkaline liquid flowing out of the equipment.

[0004] If the alkaline liquid is directly recycled into the corresponding container, alkaline foam will overflow from the container before it is fully filled, thus affecting the recycling efficiency. Moreover, excessively large bubbles will also affect the stability of the alkaline foam layer, thereby affecting subsequent processing steps. Utility Model Content

[0005] This application provides a foam treatment device to solve the technical problem that excessively large bubbles in liquid foam affect recycling.

[0006] This application provides a foam processing device, including a container, a bubble generator, and a stirring mechanism. The container has a cavity for containing liquid; the bubble generator is disposed at the bottom of the container and is used to generate microbubbles in the liquid within the cavity; the stirring mechanism is connected to the container and is horizontally positioned to stir the liquid in the cavity.

[0007] In an optional embodiment of this application, the stirring mechanism includes a stirring cylinder and a driving module; the stirring cylinder extends along the Y direction and is rotatably connected to the container, and the stirring cylinder is located inside the cavity; the driving module is disposed on one side of the container in the Y direction and located outside the cavity, and the driving module is used to drive the stirring cylinder to rotate.

[0008] In an optional embodiment of this application, the stirring drum includes a rotating shaft, multiple stirring discs, and multiple stirring plates; one end of the rotating shaft is rotatably connected to one side wall of the container in the Y direction, and the other end passes through the other side wall of the container in the Y direction and is connected to the drive module; multiple stirring discs are connected to the rotating shaft and arranged at intervals along the axial direction of the rotating shaft, and multiple stirring plates are connected to each stirring disc and arranged at intervals along the circumferential direction of the stirring discs.

[0009] In an optional embodiment of this application, the mixing disc includes a turntable portion and multiple ear plates; each ear plate extends outward from the turntable portion along the radial direction of the turntable portion, and the multiple ear plates are arranged at intervals along the circumference of the turntable portion, with the rotating shaft passing through the turntable portion of each mixing disc.

[0010] In an optional embodiment of this application, at least one stirring plate is connected to each of two adjacent ear plates in the same stirring pan on opposite sides.

[0011] In an optional embodiment of this application, the foam treatment device further includes a feed pipe and a discharge pipe; both the feed pipe and the discharge pipe are located on the peripheral sidewall of the container and communicate with the cavity, and the height of both the feed pipe and the discharge pipe is lower than the rotation axis of the stirring mechanism.

[0012] In an optional embodiment of this application, the bubble generator includes multiple nozzles, all of which are oriented toward the cavity and arranged in a rectangular array on the bottom sidewall of the container.

[0013] In an optional embodiment of this application, the foam processing device further includes a trolley, which includes a base and multiple wheels; the multiple wheels are all connected to the base, and the container is placed on the base.

[0015] In an optional embodiment of this application, the container is made of a corrosion-resistant material.

[0016] In summary, the foam treatment apparatus provided in this application has at least the following beneficial effects:

[0017] In this embodiment, a cavity is formed inside the container to hold the liquid. A bubble generator acts on the liquid in the cavity R to form microbubbles. The bubble generator is installed at the bottom of the container, so the microbubbles formed can move upward from the bottom and act on the liquid entering the container, causing the large bubbles that are already present in the liquid to dissolve and break, so that the bubbles in the liquid in the container exist as much as possible in the form of microbubbles.

[0018] Furthermore, the horizontally positioned stirring mechanism can agitate the liquid in the cavity. This agitation ensures that microbubbles are evenly mixed with the liquid and that the bubbles dissolve quickly, reducing the formation of large bubbles. In other words, the main purpose of the stirring mechanism is to break up the bubbles and help eliminate foam.

[0019] In practical applications, this foam treatment device can be used to treat alkaline foam in alkaline liquids, eliminating alkaline foam in alkaline liquids. This ensures that the container used for liquid recovery can be filled as much as possible, guaranteeing recovery efficiency and reducing the risk of subsequent processing steps being affected by excessively large bubbles.

[0031] In this application, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can be a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In the description of this specification, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0033] The “X direction”, “Y direction” and “Z direction” mentioned in this application are based on the rectangular coordinate system constructed by the foam treatment device, where the Z direction is the up and down direction, and the X and Y directions are the horizontal directions, and the three are perpendicular to each other.

[0034] Figure 1 This is a schematic diagram of a foam treatment apparatus provided according to one embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the foam treatment device from another perspective. Figure 3 for Figure 1 A partial cross-sectional view of the foam treatment unit. See also... Figures 1 to 3 In some alternative embodiments, the foam treatment device includes a container 10, a bubble generator 20, and a stirring mechanism 30.

[0035] A cavity R for containing liquid is formed inside the container 10. A bubble generator 20 is disposed at the bottom of the container 10 and is used to generate microbubbles in the liquid in the cavity R. A stirring mechanism 30 is connected to the container 10 and is arranged horizontally to stir the liquid in the cavity R.

[0036] In this embodiment, a cavity R is formed inside the container 10 to hold liquid, which may refer to a cleaning liquid that generates bubbles.

[0037] The bubble generator 20 acts on the liquid in the cavity R to form microbubbles. These microbubbles primarily refer to nanobubbles, with diameters ranging from micrometers to nanometers. In specific applications, high-pressure gases (such as ozone, oxygen, and air) can be passed through a microporous structure to form nanobubbles. It should be noted that nanobubbles possess properties such as oxygenation, enhanced ozonation, and increased biological activity, leading to their widespread application in water treatment.

[0038] The bubble generator 20 is installed at the bottom of the container 10. The microbubbles formed in this way can move from the bottom to the top and act on the liquid entering the container R, causing the large bubbles that are originally present in the liquid to dissolve and break, so that the bubbles in the liquid in the container 10 exist as microbubbles as possible.

[0039] Furthermore, the horizontally positioned stirring mechanism 30 can stir the liquid in the cavity R. It should be noted that, due to their small size and large specific surface area, nano-sized bubbles have a longer residence time in the liquid. Stirring by the stirring mechanism 30 can make the micro-bubbles uniformly mixed with the liquid and allow the bubbles to dissolve quickly, reducing the formation of large bubbles. That is, the main purpose of the stirring mechanism 30 is to break up the bubbles and help eliminate foam.

[0040] Understandably, air bubbles in a liquid will rise to the surface. In practical applications, the liquid in the cavity R will not completely submerge the stirring mechanism 30. Setting the stirring mechanism 30 to a horizontal position can break up the upper air bubbles and make it easier to mix the upper air bubbles with the liquid during the stirring process, thus achieving a better bubble breaking effect.

[0041] In a further optional embodiment, the stirring mechanism 30 includes a stirring cylinder 31 and a drive module 32. The stirring cylinder 31 extends along the Y direction and is rotatably connected to the container 10, and the stirring cylinder 31 is located within the cavity R. The drive module 32 is disposed on one side of the container 10 in the Y direction and located outside the cavity R, and the drive module 32 is used to drive the stirring cylinder 31 to rotate.

[0042] In this embodiment, the stirring mechanism 30 includes at least a stirring cylinder 31 and a drive module 32. By controlling the drive module 32 located outside the cavity R to rotate the stirring cylinder 31 located in the cavity R, the liquid in the cavity R is stirred, thereby breaking up bubbles and accelerating the dissolution of bubbles.

[0043] It should be noted that the mixing drum 31 and the drive module 32 are not limited to the layout along the Y direction. For example, they can also be laid out along the X direction or other horizontal directions, as long as the mixing mechanism 30 is arranged in the horizontal direction.

[0044] In specific applications, the drive module 32 is a module based on a motor. For example, it can be a direct drive solution or a drive solution that combines a motor with a transmission mechanism (such as a gear set or a synchronous belt).

[0045] It should be noted that the terms "axial", "circumferential" and "radial" mentioned in the following description can be understood with reference to the orientation of the mixing tank 31.

[0046] In a further optional embodiment, the stirring tank 31 includes a rotating shaft 311, a plurality of stirring discs 312, and a plurality of stirring plates 313. One end of the rotating shaft 311 is rotatably connected to one side wall of the container 10 in the Y direction, and the other end passes through the other side wall of the container 10 in the Y direction and is connected to the drive module 32.

[0047] Multiple mixing discs 312 are connected to the rotating shaft 311 and are arranged at intervals along the axial direction of the rotating shaft 311. Multiple mixing plates 313 are connected to each mixing disc 312 and are arranged at intervals along the circumferential direction of the mixing disc 312.

[0048] In this embodiment, the stirring drum 31 includes at least a rotating shaft 311, a plurality of stirring discs 312, and a plurality of stirring plates 313. The rotating shaft 311 extends along the Y direction and is rotatably connected to the container 10, and one end is driven to rotate by the driving module 32.

[0049] Multiple mixing discs 312 are arranged at intervals along the axial direction of the rotating shaft 311. Since the rotating shaft 311 is arranged at intervals along the Y direction, the multiple mixing discs 312 are also arranged at intervals along the Y direction.

[0050] Furthermore, each mixing disc 312 is connected to a plurality of mixing plates 313, which are arranged at intervals around each mixing disc 312.

[0051] Thus, the stirring drum 31 is formed by connecting the stirring plate 312, which is arranged at intervals in the Y direction, through the rotating shaft 311 and multiple circumferentially spaced stirring plates 313. The rotating shaft 311 serves as the power input shaft, driving the stirring plate 312 and stirring plates 313 to rotate together to achieve the stirring function.

[0052] In a further optional embodiment, the mixing disc 312 includes a turntable portion 3121 and a plurality of ear plates 3122. Each ear plate 3122 extends radially outward from the turntable portion 3121, and the plurality of ear plates 3122 are arranged at circumferential intervals along the turntable portion 3121. The rotating shaft 311 passes through the turntable portion 3121 of each mixing disc 312.

[0053] In this embodiment, the stirring plate 312 is composed of a turntable portion 3121 and a plurality of ear plates 3122 connected to the turntable portion 3121 and arranged at intervals along the circumference. These ear plates 3122 all extend radially outward from the turntable portion 3121.

[0054] In practical applications, a through hole is formed in the center of the turntable 3121 to allow the rotating shaft 311 to pass through, thereby enabling the stirring discs 312 arranged at intervals in the Y direction to be connected in sequence.

[0055] In a further optional embodiment, at least one stirring plate 313 is connected to each of two adjacent ear plate portions 3122 in the same stirring pan 312 on one side facing each other.

[0056] In this embodiment, for two adjacent ear plate portions 3122 in the same stirring pan 312, a stirring plate 313 is fixedly installed on each of their respective sides facing each other. Thus, each ear plate portion 3122 corresponds to at least two stirring plates 313, wherein at least two stirring plates 313 need to be located on both sides of the ear plate portion 3122. It can be seen that the stirring plates 313, in conjunction with the ear plate portions 3122, form the impeller of the stirring cylinder 31 to achieve the stirring function.

[0057] In some optional embodiments, the foam treatment device further includes a feed pipe 40 and a discharge pipe 50. Both the feed pipe 40 and the discharge pipe 50 are disposed on the peripheral sidewall of the container 10 and communicate with the cavity R. The height of both the feed pipe 40 and the discharge pipe 50 is lower than the rotation axis of the stirring mechanism 30.

[0058] In this embodiment, the feed pipe 40 and the discharge pipe 50 are connected to an external liquid circulation system. The feed pipe 40 introduces liquid into the cavity R, and the discharge pipe 50 leads the liquid out of the cavity R.

[0059] Understandably, the liquid introduced from the feed pipe 40 is a liquid with large bubbles, and the liquid drawn from the discharge pipe 50 is the liquid after foam elimination and sedimentation.

[0060] It should be noted that the liquid level in the cavity R generally will not exceed the rotation axis of the stirring mechanism 30, that is, it will not exceed the height of the rotating shaft 311. In this embodiment, the installation height of the feed pipe 40 and the discharge pipe 50 is set below the rotating shaft 311.

[0061] The discharge pipe 50 is installed below the rotating shaft 311 to ensure that the liquid in the cavity R can be discharged. Preferably, the discharge pipe 50 is set close to the bottom of the container 10 to ensure that the liquid in the cavity R can be completely discharged. The installation height of the feed pipe 40 is also below the rotating shaft 311, mainly to avoid liquid splashing caused by the height difference between the feed position and the liquid surface in the cavity R.

[0062] In the illustrated embodiment, the feed pipe 40 and the discharge pipe 50 are both located on the same side wall of the container 10 and on the same side as the drive module 32. Of course, it is not limited to the illustrated embodiment and the design can be adjusted according to requirements.

[0063] In some alternative embodiments, the bubble generator 20 includes a plurality of nozzles 21, all of which are oriented toward the cavity R and arranged in a rectangular array on the bottom sidewall of the container 10.

[0064] In this embodiment, the nozzles 21 located on the bottom sidewall of the container 10 form a microporous structure layer. These nozzles 21 are connected to an air source, and nanoscale bubbles can be formed in the liquid in the cavity R by means of these nozzles 21 and the air source.

[0065] These nozzles 21 cover the entire bottom sidewall of the container 10 and are arranged in a rectangular array, thus enabling the liquid in the cavity R to form large-area uniformly distributed and upward-moving nanoscale bubbles.

[0066] In a further optional embodiment, the foam treatment device further includes a control module 70, which is connected to the bubble generator 20 and the stirring mechanism 30 to control the operation of the bubble generator 20 and the stirring mechanism 30.

[0067] In this embodiment, the control module 70 is used to control the bubble generator 20 and the stirring mechanism 30. Here, the control module 70 controls the rotation speed of the entire stirring mechanism 30 by controlling the drive module 32.

[0068] It should be noted that the bubble generator 20 also includes a gas path control system (not shown in the figure). The gas path control system includes a signal feedback module, which mainly includes, for example, pressure sensors, gas path control valves, flow sensors, etc. The control module 70 can acquire information from pressure sensors, flow sensors, etc., and adjust each gas path control valve according to this information to achieve real-time adjustment of bubble generation, size and collapse.

[0069] In addition, the control module 70 can be divided into a bubble control unit and a stirring control unit. The bubble control unit is used to control the bubble generator 20, and the stirring control unit is used to control the rotation speed of the stirring mechanism 30.

[0070] Understandably, the control module 70 can be a microprocessor-based functional module that controls the operation of the bubble generator 20 and the stirring mechanism 30, and also integrates instruction input / output modules such as buttons and displays to facilitate operation by operators.

[0071] In some alternative embodiments, the foam handling apparatus further includes a trolley 60, which includes a base 61 and a plurality of wheels 62. The plurality of wheels 62 are all connected to the base 61, and the container 10 is placed on the base 61.

[0072] In this embodiment, the container 10 is placed on the base 61 of the trolley 60, so the foam treatment device has a degree of freedom of movement and can be moved to the desired position as needed.

[0073] In practical applications, wheel 62 is a swivel wheel to ensure flexibility during movement, and the number of wheels 62 is no less than 3.

[0074] In the illustrated embodiment, the container 10 is a rectangular container, the base 61 is a rectangular plate, and there are 4 wheels 62 located at the 4 corners of the base 61. Of course, the number and arrangement of the wheels 62 are not limited to the illustrated embodiment.

[0075] In some alternative embodiments, container 10 is made of a corrosion-resistant material. In specific applications, it may be made of materials such as stainless steel, glass, or ceramic.

[0076] As can be seen, the container 10 can be used to contain cleaning reagents with a certain degree of corrosiveness. In specific applications, this foam treatment device can be used for the treatment of alkaline foam in alkaline liquids.

[0077] Specifically, alkaline liquid can enter the cavity R through the feed pipe 40. The control module 70 controls the bubble generator 20 to form bubbles of the required size in the liquid and dissolve and break up the large bubbles present in the alkaline liquid. At this time, alkaline foam will be generated. At the same time, the drive module 32 is started to make the stirring mechanism 30 stir, so that the alkaline foam is evenly distributed and quickly dissolved and broken up, which helps to eliminate the alkaline foam. After the alkaline foam is eliminated and settled, it is discharged from the cavity R through the discharge pipe 50.

[0078] Thus, after the alkaline liquid is cleaned and passes through this foam treatment device, there will be no large air bubbles or alkaline foam in the liquid. This ensures that the container used for liquid recovery can be filled as completely as possible, guaranteeing recovery efficiency and reducing the risk of large air bubbles affecting subsequent processing steps. It should be noted that this foam treatment device is not limited to treating alkaline foam in alkaline liquids.

[0079] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
