Description

Technical Field

[0001] This invention relates to the field of cleaning agent production technology, and in particular to a cleaning liquid stirring tank dispersion component and a cleaning liquid stirring device. Background Technology

[0002] The industrial production of cleaning agents usually involves mechanical stirring to quickly and uniformly dissolve and disperse various solid or liquid functional components (such as surfactants, detergent builders, polymers, etc.) in a solvent (usually water), ultimately forming a homogeneous and stable liquid product.

[0003] However, powdered raw materials do not always dissolve ideally and uniformly when in contact with liquid solvents. If wetting is insufficient, the dissolution rate is slow, or the stirring shear force is inadequate, the surface of the powder particles will rapidly hydrate to form a viscous gel layer, which will encapsulate the internal dry powder, causing them to stick together and form insoluble "fish-eye" or clump-like structures ranging from micrometers to millimeters in size. These agglomerates not only affect production efficiency and pipeline flow but also impair the transparency, stability, and cleaning effectiveness of the final product.

[0004] To address the agglomeration problem, existing technologies often employ high-shear dispersers, which provide stronger shearing forces, to effectively break up agglomerates. However, high-shear dispersers are too expensive, increasing production costs. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a cleaning fluid stirring tank dispersion component and a cleaning fluid stirring device to solve the problem that the high cost of high shear dispersers increases production costs.

[0006] This invention provides a cleaning fluid stirring tank dispersion assembly, comprising: A layered module is installed in the mixing tank to separate the upper and lower parts of the mixing tank and control the connection between the upper and lower parts of the mixing tank. A dispersion module is disposed below the layered module and is used to disperse the material passing through the dispersion module; A conveying auger connects the upper and lower layers of the mixing tank, used to transport material from the lower layer back to the upper layer, so that the material circulates through the dispersion module.

[0007] Optionally, the distributed module includes: A fixing plate is fixedly connected to the mixing tank, and the fixing plate is provided with a plurality of first through holes; A vibrating plate is disposed below the fixed plate and is movably connected to the stirring tank. The vibrating plate is provided with a plurality of second through holes that are aligned one-to-one with the first through hole. The diameter of the second through hole is smaller than the diameter of the first through hole. A breaking needle is disposed in at least one of the first through hole and the second through hole; An elastic membrane is disposed between the first through hole and the second through hole to form a flexible channel between the first through hole and the second through hole, and the peristalsis of the flexible channel is controlled according to the vibration of the shaking plate.

[0008] Optionally, the dispersion module further includes an inner tube, which is fixedly disposed on the fixed plate and disposed in the flexible channel. The inner tube connects the upper and lower layers of the dispersion module. A filter screen is disposed at the top of the inner tube. The inner tube is used to transport the liquid from the upper layer of the dispersion module to the lower layer of the dispersion module and mix it with the agglomerates transported to the lower layer of the dispersion module through the flexible channel.

[0009] Optionally, the inner tube is further provided with a piston for closing the inner tube when the flexible channel contracts and opening the inner tube when the flexible channel expands.

[0010] Optionally, a top cover is fixedly provided at the top of the inner tube. The diameter of the top cover is larger than the outer diameter of the inner tube, and filter holes are opened on the bottom surface of the top cover to form the filter screen.

[0011] Optionally, the piston is inverted conical, and a push block is elastically connected to the inner tube. The push block is arranged laterally, with its inner end matching the inclined surface of the piston's conical surface and its outer end matching the inclined surface of the second through hole. When the vibrating plate moves above the pushing block, the pushing block pops outward and separates from the piston, causing the piston to fall into the valve area inside the inner tube, closing the valve area and blocking the inner tube; When the vibrating plate moves to the pushing block, the inner wall of the second through hole pushes the pushing block into the inner tube, pushes the piston upward, and moves the piston out of the valve area, opening the inner tube.

[0012] Optionally, the breaking needle is also disposed on the inner tube.

[0013] Optionally, the vibrating plate is slidably connected to the side wall of the mixing tank, or is sealed by an elastic membrane.

[0014] Another aspect of the present invention provides a cleaning fluid stirring device, including a stirring tank, wherein the stirring tank is provided with the above-mentioned cleaning fluid stirring tank dispersion component.

[0015] Optionally, the mixing tank is also equipped with a liquid level monitor to monitor the liquid level in the mixing tank, so as to monitor whether the dispersion module is blocked based on the liquid level.

[0016] The cleaning fluid mixing tank dispersion assembly provided by this invention features a layered module that controls the connection between the upper and lower layers of the mixing tank. A dispersion module is located below the layered module to disperse the material passing through it. A conveying auger connects the upper and lower layers of the mixing tank, transporting the material from the lower layer back to the upper layer. After the material is pre-mixed in the upper layer of the mixing tank to the desired consistency, the layered module opens, activating the conveying auger. This allows the material in the upper layer to be dispersed by the dispersion module and then transported to the lower layer, before being returned to the upper layer by the conveying auger. This allows the material to circulate through the dispersion module, continuously dispersing agglomerates and improving the mixing efficiency of the cleaning fluid. This reduces the need for high-shear mixers in cleaning fluid production, lowering production costs. Furthermore, it can be combined with high-shear mixers to further improve the efficiency of dispersing agglomerates and increase overall production efficiency. Attached Figure Description

[0019] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To address the issue of excessively high costs associated with high-shear dispersers, which increase production costs, this invention provides a dispersion component for a cleaning fluid mixing tank. This component features a layered module that controls the connection between the upper and lower layers of the mixing tank. A dispersion module is positioned below the layered module to break up materials passing through it. A conveyor auger connects the upper and lower layers of the mixing tank, transporting material from the lower layer back to the upper layer. After pre-mixing the material in the upper layer of the mixing tank to the desired consistency, the layered module opens, activating the conveyor auger. This allows the material to be dispersed by the dispersion module and then transported to the lower layer, before being returned to the upper layer by the auger. This allows for continuous material circulation through the dispersion module, breaking up agglomerates and improving the mixing efficiency of the cleaning fluid. This reduces the need for high-shear mixers in cleaning fluid production, lowering production costs. Furthermore, it can be combined with high-shear mixers to further enhance the efficiency of breaking up agglomerates and improve overall production efficiency.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, the cleaning fluid stirring device includes a stirring tank 1. The top cover of the stirring tank 1 is provided with a feed inlet 2, the bottom is provided with a discharge outlet 3, the inside is provided with a rotating shaft 5, and a stirring rod 6 is fixedly provided on the rotating shaft 5. The top of the stirring tank 1 is also provided with a stirring motor 4. The stirring motor 4 drives the rotating shaft 5, and then drives the stirring rod 6 to stir the material inside the stirring tank 1.

[0024] The cleaning fluid mixing tank dispersion assembly is installed inside the mixing tank 1, dividing the mixing tank 1 into upper and lower layers. A conveying auger 7 is fixed to a rotating shaft 5, and an auger cylinder 8 outside the conveying auger 7 is fixedly installed inside the mixing tank 1. The conveying auger 7 and the auger cylinder 8 connect the upper and lower layers of the mixing tank 1. The material is dispersed by the cleaning fluid mixing tank dispersion assembly and conveyed to the lower layer. Then, the conveying auger 7 returns the material from the lower layer to the upper layer, allowing the material to circulate and be dispersed through the cleaning fluid mixing tank dispersion assembly, ensuring dispersion efficiency and thus improving the mixing efficiency of the cleaning fluid.

[0025] The bottom of the auger drum 8 is also equipped with a drum support 9, which is fixedly connected to the mixing tank 1. The drum support 9 or the lower part of the auger drum 8 is provided with a return opening as a channel for material return, so that the material can reach the working area of ​​the conveying auger 7 and realize return circulation. In order to avoid some material settling below the drum support 9 and not being able to circulate effectively, a return opening is provided on the auger drum 8. Correspondingly, a movable door can be provided on the drum support 9. The movable door is linked with the discharge valve and opens and closes with the opening and closing of the discharge valve, so that the material reaches the bottom of the drum support 9 only after the material has been mixed and discharged.

[0026] Please refer to further details. Figure 3 In this embodiment, the partition module includes a partition plate 10 and a movable plate 11. The partition plate 10 is fixedly connected to the inner wall of the mixing tank 1 and concentrically fixedly connected to the auger cylinder 8 in the middle, achieving upper and lower sealing separation. The movable plate 11 is sealed and stacked below the partition plate 10. The movable plate 11 is fixedly connected to the gear ring 16, and the movable plate 11 and the gear ring 16 are loosely fitted on the auger cylinder 8. The gear ring 16 is meshed with the drive gear 15, and the drive gear 15 is driven by the drive motor 14.

[0027] The partition plate 10 and the movable plate 11 are respectively provided with a first through groove 12 and a second through groove 13. The drive motor 14 controls the rotation of the movable plate 11 through the drive gear 15 and the gear ring 16, thereby controlling whether the second through groove 13 coincides with or is offset from the first through groove 12. When the second through groove 13 coincides with the first through groove 12, the partition module connects the upper and lower layers of the mixing tank 1. When they are completely offset, the upper and lower layers of the mixing tank 1 are separated. During the feeding and pre-mixing of materials, the partition module separates the upper and lower layers of the mixing tank 1.

[0028] Please refer to further details. Figure 4 , Figure 5 and Figure 7 The dispersing module is located below the separating module and includes a fixed plate 17 and a shaking plate 18. The fixed plate 17 is fixedly connected to the mixing tank 1, and the shaking plate 18 is sealed to the fixed plate 17.

[0029] The fixed plate 17 and the shaking plate 18 are respectively provided with a first through hole 21 and a second through hole 22. The diameter of the first through hole 21 is larger than that of the second through hole 22. An elastic membrane 19 is provided between the first through hole 21 and the second through hole 22. The flexible channel connecting the upper and lower parts of the dispersion module is formed by the first through hole 21, the second through hole 22 and the elastic membrane 19. When the shaking plate 18 shakes up and down relative to the fixed plate 17, the flexible channel can peristalse, and the peristaltic power promotes the downward conveying of materials.

[0030] Crushing needles 36 are provided on the inner walls of the first through hole 21 and the second through hole 22. When agglomerates in the material are conveyed downward through the flexible channel, the agglomerates can be crushed by the crushing needles 36. In this embodiment, crushing needles 36 are provided on the inner walls of both the first through hole 21 and the second through hole 22, respectively, for crushing larger agglomerates and smaller agglomerates, which are carried out sequentially, constituting two crushing processes to improve crushing efficiency.

[0031] During the peristalsis of the flexible channel, due to the characteristic of the flexible channel being larger at the top and smaller at the bottom, some of the material located in the flexible channel will be pushed upward and then re-enter the flexible channel, so that it can repeatedly pass through the crushing needle 36 in the first through hole 21 and be crushed multiple times, which can further improve the crushing effect.

[0032] The fixed plate 17 and the vibrating plate 18 are sealed together by a connector 20. The connector 20 can be an elastic diaphragm or a rigid plate and a groove to meet the up-and-down vibrating operation requirements of the vibrating plate 18. An elastic diaphragm facilitates sealing and is preferred. A rigid plate and a groove ensure the directionality of the up-and-down vibration; the specific choice can be made flexibly according to actual needs. The vibration of the vibrating plate 18 can be achieved by a vibrating motor, which can be installed in the sealed space between the fixed plate 17 and the vibrating plate 18. The power supply and communication cables for the vibrating motor can be arranged in the fixed plate 17.

[0033] When agglomerates pass through the dispersion module, they can obstruct the material transport and hinder the delivery of solvent. This can cause the agglomerates to re-agglomerate after reaching the lower layer due to insufficient solvent. To avoid this re-agglomeration problem, in this embodiment, the dispersion module also includes an inner tube 23. The inner tube 23 is fixedly connected to the fixing plate 17 through an inner tube support 24. The inner tube 23 is set in a flexible channel, connecting the upper and lower layers of the dispersion module, and is used for solvent delivery. This allows the solvent to be delivered downwards through the inner tube 23, ensuring that the lower layer has sufficient solvent and preventing the agglomerates in the lower layer of the dispersion module from re-agglomerating due to insufficient solvent, thereby ensuring the agglomerate dispersing effect.

[0034] In this embodiment, the liquid outlet 28 at the bottom of the inner tube 23 is inclined to facilitate timely mixing of the material discharged from the inner tube 23 with the agglomerates discharged from the second through hole 22, thereby reducing the risk of re-agglomeration.

[0035] The inner tube 23 is installed in the flexible channel and has a small diameter. To prevent aggregates from entering and blocking the inner tube 23, such as... Figure 6 As shown, a filter screen 26 is also provided at the top of the inner tube 23 to prevent aggregates from entering. Specifically, a top cover 25 is fixedly provided at the top of the inner tube 23. The diameter of the top cover 25 is larger than the outer diameter of the inner tube 17. Filter holes are opened on the bottom surface of the top cover 25 to form the filter screen 26. By placing the filter screen 26 on the bottom surface of the top cover 25, aggregates can be prevented from naturally depositing on the filter screen 26, thus preventing the filter screen 26 from becoming clogged.

[0036] When the vibrating plate 18 moves upward, the flexible channel contracts, and some of the material in it flows upward, which may block the filter screen 26. At this time, in order to avoid the filter screen 26 from being blocked, the inner tube 23 can be temporarily closed, and the inner tube can be opened again when the flexible channel expands.

[0037] To achieve the switching control of the inner tube 23, in this embodiment, as follows: Figure 7 As shown, the bottom dimension of the inner tube 23 is increased to form an expansion tube 27. An expansion groove 29 and a valve area are provided in the expansion tube 27 for the placement of the piston 30 and the opening and closing control of the piston on the inner tube 23. When the piston 30 is located in the valve area, the piston 30 is sealed and fitted with the inner wall of the expansion tube 27, and the passage of the inner tube 23 is closed.

[0038] The piston 30 is inverted conical, and a positioning pin 34 is provided at the bottom of the expansion tube 27. A positioning hole 35 is provided in the piston 30. The positioning pin 34 and the positioning hole 35 are nested together to ensure the vertical movement of the piston 30, thereby ensuring the reliability of the docking between the piston 30 and the valve area inside the expansion tube 27, and ensuring the reliability of the opening and closing of the inner tube 23.

[0039] A push block 31 is also elastically connected to the inner tube 17 via a spring 32. The push block 31 is arranged laterally, with its inner end matching the conical inclined surface of the piston 30, and its outer inclined surface 33 matching the inclined surface of the second through hole 22. When the vibrating plate 18 moves above the push block 31, the spring 32 ejects the push block 31 outward, separating it from the piston 30, allowing the piston 30 to fall into the valve area, closing the valve area and blocking the inner tube 23.

[0040] When the vibrating plate 18 moves to the pushing block 31, the inner wall of the second through hole 22 can push the pushing block 31 into the inner tube 23 through the outer inclined surface 33, so that the pushing block 31 pushes the piston 30 upward, so that the piston 30 separates from the docking cone surface and opens the passage of the inner tube 23.

[0041] When the pusher block 31 pushes the piston 30 upward, the upward movement of the piston 30 can also drive the liquid in the inner tube 23 to be transported upward, which can reverse the slight blockage of the filter screen 26.

[0042] To improve crushing efficiency, in this embodiment, the crushing needle 36 is also provided on the inner tube 23, so that when the shaking plate 18 shakes up and down, the crushing needle on the inner tube 23 and the crushing needle on the second through hole 22 can move relative to each other, thereby improving the crushing effect.

[0043] In the later stages of mixing, the remaining agglomerates are smaller, which can reduce the shaking amplitude of the shaking plate 18, allowing the push plate 31 to remain confined in the second through hole 22, maintaining the opening of the inner tube 23. At the same time, in the later stages of mixing, the shaking amplitude of the shaking plate 18 can be periodically increased to periodically clear the filter screen 26.

[0044] like Figure 4 As shown, a liquid level monitor 37 is also provided on the mixing tank 1. In this embodiment, it is a non-contact monitor, which is set on the upper part of the mixing tank 1 to monitor the liquid level of the cleaning agent in the mixing tank 1 in real time. When the channel of the dispersing module is smooth, the material circulation is stable and the liquid level fluctuation is within the expected range. When the channel of the dispersing module is blocked, the liquid level rises and exceeds the expected range, and the circulation is not smooth. At this time, the shaking amplitude of the shaking plate 18 can be increased to increase the peristaltic conveying capacity of the flexible channel and clear the channel of the dispersing module.

[0045] The cleaning fluid mixing tank dispersion component and cleaning fluid mixing device provided by this invention control the connection between the upper and lower layers of the mixing tank through a layered module. A dispersion module is set below the layered module to disperse the material passing through the dispersion module. A conveying auger connects the upper and lower layers of the mixing tank, conveying the material from the lower layer back to the upper layer. After the material is pre-mixed in the upper layer of the mixing tank to the desired consistency, the layered module opens, and the conveying auger is activated, allowing the material in the upper layer to be dispersed by the dispersion module and then conveyed to the lower layer, and then sent back to the upper layer by the conveying auger. This allows the material to circulate through the dispersion module, continuously dispersing agglomerates, improving the mixing efficiency of the cleaning fluid, reducing the need for high-shear mixers in cleaning fluid production, reducing production costs, and can be combined with high-shear mixers to improve the efficiency of dispersing agglomerates, further improving production efficiency.
