Technical Field

[0001] This application relates to the field of liquid mixing technology, and in particular to a liquid material mixing device and mixing system. Background Technology

[0002] In industrial production, the mixing of liquid materials is a crucial step in many chemical and materials processing technologies, as the mixing effect directly impacts the quality stability and performance indicators of subsequent products. Currently, the industry commonly uses stirring and mixing methods to achieve the mixing of liquid materials.

[0003] This traditional mixing method has significant drawbacks: it relies on mechanical stirring devices to drive the flow of materials to achieve mixing, and uneven mixing in some areas is likely to occur during the mixing process. To ensure the mixing effect, the stirring time needs to be extended.

[0004] In large-scale continuous production scenarios, the lengthy processing time required for mixing and stirring leads to extended production cycles, making it impossible to match the demands of high-volume production and severely restricting the improvement of overall production efficiency. Therefore, there is an urgent need for an efficient liquid material mixing technology to solve the problem of low efficiency in existing mixing methods and their inability to meet the needs of continuous, high-volume production.

[0033] To improve the efficiency of uniform mixing of liquid materials, please refer to [link / reference needed]. Figures 1 to 4This application provides a liquid material mixing device for efficiently and uniformly mixing multiple liquid materials. Specifically, the liquid material mixing device includes a mixing chamber 10 and a material holding chamber 20. The mixing chamber 10 includes a first chamber 101, a second chamber 102, and a third chamber 103 that are isolated from each other. The first chamber 101 is provided with a plurality of first nozzles 30 for spraying different liquid materials into the first chamber 101. The second chamber 102 is connected to the first chamber 101 by an overflow channel 50. The third chamber 103 is connected to the second chamber 102 by a flow channel 60, and the third chamber 103 is provided with a second nozzle 40 for spraying into the material holding chamber 20.

[0034] The mixing method of this liquid material mixing device is as follows: First, multiple liquid materials to be mixed are sprayed into the first chamber 101 through multiple first nozzles 30 for initial mixing. After the liquid level in the first chamber 101 reaches the overflow channel 50, the liquid material at the top of the first chamber 101 overflows into the second chamber 102, where it undergoes a second mixing. The liquid material in the second chamber 102 then flows through the flow channel 60 to the third chamber 103, where it undergoes a third mixing. Finally, the liquid material in the third chamber 103 is sprayed into the storage chamber 20 through second nozzles 40 for storage and later use. The spraying process through the second nozzles 40 further mixes the liquid materials, improving the mixing uniformity. When there is a need for the mixed liquid material, it can be taken from the storage chamber 20.

[0035] Both the first nozzle 30 and the second nozzle 40 spray liquid materials in a spraying manner, which helps to improve the mixing efficiency and uniformity of the liquid materials. Specifically, multiple first nozzles 30 spray different liquid materials separately, dispersing the liquid materials into fine droplets, increasing the contact surface area between the liquid phases of different liquid materials, shortening the diffusion path of liquid material molecules, and accelerating the mass transfer and mixing process of liquid materials. The second nozzle 40 sprays the mixed liquid materials again, thereby forming the mixed liquid materials into fine droplets, further increasing the opportunities for liquid phase molecule contact and mass transfer, effectively reducing the probability of local uneven concentration of the mixed liquid materials, and ensuring the uniform mixing effect of the liquid materials. In addition, in some preferred embodiments, the spray range of the first nozzle 30 is conical; and / or, the spray range of the second nozzle 40 is conical. Such nozzle configuration is beneficial for controlling the spray range and spray flow rate.

[0036] The first chamber 101 and the second chamber 102 transfer the mixed liquid material through an overflow, achieving natural turbulence of the liquid material, promoting its diffusion, and improving mixing uniformity. Furthermore, when the first nozzle 30 continuously sprays the liquid material, the overflow transfer between the first chamber 101 and the second chamber 102 eliminates the need for additional power sources to drive the liquid material flow.

[0037] A flow passage 60 is provided between the second chamber 102 and the third chamber 103 to accelerate the flow velocity of the liquid mixture, shorten the diffusion time of the liquid material, and improve the mixing efficiency. In addition, the flow passage can enhance the turbulence intensity of the liquid material flow, promote the mass transfer effect at the molecular level, and improve the mixing uniformity of the liquid material. Specifically, along the direction perpendicular to the liquid material flow, the cross-section of the flow passage 60 is smaller than the cross-section of the second chamber 102 and the third chamber 103, so that the flow velocity of the liquid material in the flow passage 60 is relatively faster than that in the second chamber 102 and the third chamber 103, thereby improving the mixing efficiency and mixing uniformity of the liquid material during the flow from the second chamber 102 to the third chamber 103.

[0038] In some embodiments of this application, see Figure 3 Each first nozzle 30 sprays towards the bottom of the first chamber 101 to reduce the amount of unmixed liquid material sprayed from the first nozzle 30 directly entering the second chamber 102 through the overflow channel 50, thus avoiding affecting the overall mixing effect of the liquid material. In some other embodiments of this application, the spray directions of any two first nozzles 30 intersect, thereby enhancing the contact between different liquid materials. Figure 4 As shown, in some embodiments, the first nozzle 30 is oriented in the same direction, allowing different liquid materials to collide and mix thoroughly during the spraying process. Preferably, see... Figure 5 The first nozzle 30 sprays downward at an angle, which reduces the amount of liquid material that directly enters the second chamber 102 through the overflow channel 50 while also taking into account the mixing effect between different liquid materials.

[0039] Furthermore, the height of the first nozzle 30 is lower than the height of the overflow channel 50, thus limiting the height of the first nozzle 30 to below the height of the overflow channel 50. This further reduces the direct entry of liquid material sprayed from the first nozzle 30 into the second chamber 102 through the overflow channel 50. Additionally, since the transfer of liquid material between the first chamber 101 and the second chamber 102 is achieved through overflow, during the overflow process, the first nozzle 30 is immersed in the liquid material in the first chamber 101. At this time, the spraying action of the first nozzle 30 creates a vortex in the liquid material in the first chamber 101, ensuring the mixing effect of the liquid material within the first chamber 101. This prevents the liquid material at the bottom of the first chamber 101 from stratifying due to prolonged stagnation, which would affect the uniformity of the liquid material mixing.

[0040] It is understandable that most liquid materials in industrial production are corrosive. In this embodiment, the first nozzle 30 needs to be immersed in the mixed liquid material. To improve the operational reliability of the first nozzle 30, the first nozzle 30, the pipe connected to the first nozzle 30, and the connection between the first nozzle 30 and the pipe can all be made of corrosion-resistant materials or structures. For example, the first nozzle 30 and the pipe can both be made of corrosion-resistant plastic, and the first nozzle 30 and the pipe can be connected by threads.

[0041] More preferably, the distance between the first nozzle 30 and the bottom wall of the first chamber 101 is d1, and the distance between the overflow channel 50 and the bottom wall of the first chamber 101 is d2, where d1 / d2 ≤ 0.5. Specifically, in the height direction, the position of the first nozzle 30 in the first chamber 101 is below the middle position of the first chamber 101, further ensuring that the liquid material sprayed from the first nozzle 30 does not directly enter the second chamber 102 through the overflow channel 50. In addition, when the first nozzle 30 sprays liquid material downwards, the sprayed liquid material will impact the bottom wall of the first chamber 101 and disperse upwards and to the sides, enhancing the mixing effect of the liquid material in the first chamber 101, especially enhancing the bottom of the first chamber 101, and improving the mixing uniformity of the liquid material.

[0042] See Figure 2 and Figure 6 In some embodiments of this application, the width of the flow channel 60 along the direction perpendicular to the liquid flow is 5mm to 10mm. The flow channel 60 is provided to increase the flow rate of the liquid material, thereby improving the mixing efficiency and uniformity of the liquid material during the transfer process from the second chamber 102 to the third chamber 103.

[0043] Specifically, the width of the flow channel 60 refers to the fact that any width of the flow channel 60 along the direction perpendicular to the liquid flow is within the range of 5mm to 10mm. For example, in Figure 6In the figure, the flow channel 60 is a circular hole channel with a radius of R, and the radius R of the circular hole channel is 5mm~10mm. Alternatively, the flow channel 60 is a strip channel (not shown in the figure), and the length and width of the strip channel along the rectangular direction perpendicular to the liquid flow direction are both in the range of 5mm~10mm.

[0044] It is understandable that the narrower the width of the flow channel 60, the faster the flow rate of the liquid material, and the better the mixing efficiency and uniformity of the liquid material. However, in actual industrial production, although an excessively narrow flow channel 60 will increase the flow rate of the liquid material, the overall liquid flow rate will decrease, affecting production efficiency. Specifically, in this application, an excessively narrow flow channel 60 will reduce the amount of liquid material entering the third chamber 103, thereby reducing the injection volume of the second nozzle 40 and affecting the material storage in the subsequent material storage chamber 20. On the other hand, an excessively wide flow channel 60 does not significantly improve the mixing efficiency and uniformity of the liquid material. In this embodiment, the width of the flow channel 60 along the direction perpendicular to the liquid flow is limited to 5mm to 10mm, which can balance the flow rate, mixing efficiency, and uniformity of the liquid material. Specifically, the width of the flow channel 60 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or any value within the range of 5mm to 10mm, and this application does not impose any restrictions on this.

[0045] In addition, when the production scale is large, multiple flow channels 60 can be provided between the second chamber 102 and the third chamber 103 to increase the liquid flow rate between the second chamber 102 and the third chamber 103.

[0046] See Figure 1 In some embodiments of this application, the second nozzle 40 is disposed on the bottom wall of the third chamber 103, and the bottom wall of the third chamber 103 extends downward at an angle toward the location where the second nozzle 40 is disposed. This design allows the liquid material in the third chamber 103 to flow toward the second nozzle 40 under the action of gravity, thereby ensuring that the second nozzle 40 stably sprays liquid material.

[0047] See Figure 1In some embodiments of this application, the liquid material mixing device includes a main body 70 and a cover 80. At least a first chamber 101 is located in the main body 70, and the cover 80 is detachably and fixedly connected to the main body 70, and the cover 80 is used to close the first chamber 101. In actual industrial production, shutdowns for maintenance are frequently required, and the liquid material in the chambers needs to be drained before maintenance of the liquid material mixing device. In this embodiment, the first chamber 101 is disposed in the main body 70 and closed by the detachable cover 80. When maintenance is required, the cover 80 is opened to drain the liquid material in the first chamber 101. It is understood that the liquid material in the second chamber 102 and the third chamber 103 can be discharged into the material storage chamber 20 in the mixing process sequence, and the liquid material in the material storage chamber 20 can be transferred to other storage containers.

[0048] In a further preferred embodiment, both the second chamber 102 and the third chamber 103 are located within the main body 70. The second chamber 102 is located beside the first chamber 101, and the third chamber 103 is located below the second chamber 102. Concentrating the first chamber 101, the second chamber 102, and the third chamber 103 within the main body 70 improves the device's compactness and reduces space occupancy. Furthermore, in this embodiment, the second chamber 102 being located beside the first chamber 101 and the third chamber 103 being located below the second chamber 102 also shortens the transfer path of the liquid material between the different chambers, improving the mixing efficiency of the liquid material.

[0049] See Figure 7 This application also provides a mixing system, including a liquid material mixing device and multiple feed channels 90 for conveying different liquid materials. The liquid material mixing device adopts any of the above embodiments. Each feed channel 90 has its outlet independently connected to a first nozzle 30. Along the material flow direction, the feed channel 90 is sequentially connected to a storage tank 901, a delivery pump 902, and a flow meter 903. The storage tank 901 is used to store liquid materials, and the type of liquid material stored in the storage tank 901 of each feed channel 90 is different. The delivery pump 902 can be a variable frequency pump, which can adjust the delivery pressure according to the production scale and liquid material ratio requirements. The flow meter 903 accurately monitors the flow rate of the liquid materials in the feed channel 90, and the flow meter 903 is electrically connected to the delivery pump 902, feeding back the monitoring results to the delivery pump 902 for flow rate adjustment. This design allows each liquid material to be sprayed independently into the first chamber 101. Depending on the actual industrial production needs, the liquid materials can be sprayed and mixed simultaneously or sequentially, and the ratio of the liquid materials can also be precisely controlled.

[0050] It is understandable that different liquid materials have different material requirements for the feed channel 90, and industrial production requires high precision in the proportioning of liquid materials. If the same feed channel 90 is used for feeding and spraying liquid materials, not only will the service life of the feed channel 90 be reduced, but the proportions of different liquid materials will also interfere with each other, affecting the mixing effect of the liquid materials.

[0051] This application provides detailed descriptions of the following hybrid system embodiments.

[0052] See Figures 1 to 8 The mixing system in this embodiment is used to mix two liquid materials, industrial raw material and acid solution, to adjust the pH value of the industrial raw material. The mixing system includes a liquid material mixing device and two feed channels 90, one feed channel 90 for conveying the industrial raw material and the other feed channel 90 for conveying the acid solution.

[0053] The liquid material mixing device includes a main body 70, a cover 80, two first nozzles 30, one second nozzle 40, and a material storage chamber 20. The material storage chamber 20 is a storage container independent of the main body 70 and the cover 80. The main body 70 has an upward-opening internal space serving as a mixing chamber 10, and the cover 80 is used to close the opening of the main body 70. A first partition 701 and a second partition 702 are fixedly installed inside the main body 70, dividing the internal space of the main body 70 into a first chamber 101, a second chamber 102, and a third chamber 103. Both the first partition 701 and the second partition 702 are integrally molded with the main body 70 using plastic material.

[0054] See Figure 8 The first partition 701 consists of, from left to right, an inclined plate 7011, a bottom plate 7012, and an overflow plate 7013. The first partition 701 is shaped like an overturned hook and encloses an upward-opening first chamber 101 within the main body 70. This design of the first chamber 101 results in a small bottom wall area, facilitating the extraction of liquid materials during maintenance. The overflow plate 7013 is vertically positioned, leaving an overflow channel 50 between its upper end and the cover plate after the cover plate closes the opening of the main body 70. Two first nozzles 30 are positioned at the middle height of the first chamber 101, and each nozzle 30 is connected to the outlet of one of the two feed channels 90. Both nozzles 30 spray downwards, with a spray range of 120°.

[0055] The second partition 702 is located to the right of the first partition 701 and is fixed to the inner wall of the main body 70. The overflow plate 7013 of the first partition 701, the second partition 702, and the inner right side wall of the main body 70 enclose a second chamber 102 with an upward opening. The second chamber 102 is located to the right of the first chamber 101. A flow passage 60 is left between the left end of the second partition 702 and the overflow plate 7013 of the first partition 701.

[0056] The third chamber 103 is located below the first chamber 101 and the second chamber 102, and is enclosed by the inclined plate 7011 and the bottom plate 7012 of the first partition 701, the second partition 702, and the bottom and side walls inside the main body 70. The bottom wall of the third chamber 103 is inclined and recessed towards the center, and the second nozzle 40 is disposed on the central bottom wall of the third chamber 103, with the outlet of the second nozzle 40 extending into the material chamber 20.

[0057] In this embodiment, when the mixing system is put into use for the first time or after maintenance and then put into use again, the flow meter 903 and the delivery pump 902 control the two first nozzles 30 to spray and mix the industrial raw liquid and acid liquid at a suitable spray flow rate. When the liquid material in the first chamber 101 is higher than the first nozzle 30, the liquid material submerges the first nozzle 30, and at this time, a vortex is formed in the first chamber 101 to mix the liquid material. When the liquid material in the first chamber 101 is higher than the overflow plate 7013, the liquid material in the first chamber 101 overflows into the second chamber 102. The liquid material in the second chamber 102 flows from the flow channel 60 to the third chamber 103, and then sprays the mixed liquid material into the material container through the second nozzle 40.

[0058] The entire mixing system eliminates the need for agitators to mix liquid materials, significantly saving mixing time, ensuring mixing effect while improving mixing efficiency, and meeting the needs of continuous high-volume production.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
