Description

Technical Field

[0001] This invention belongs to the field of liquid and powder mixing and dissolution technology, and in particular relates to a mixing device. Background Technology

[0002] Mixing and dissolving refers to the technique of mixing and dissolving several different substances to obtain a formulation with specific target components. In production activities, to accelerate the efficiency of mixing and dissolving, it is common practice to prepare solid raw materials into powder form and then mix and dissolve or emulsify them with liquid raw materials. Its applications include dissolving medicinal plants in water to produce pharmaceutical reagents, dissolving tea extracts in water to produce tea, and dissolving skin-friendly plants in water to produce skin care lotions.

[0003] In existing technologies, when a mixing and dissolving process is required, the common method is to pour the powder into a liquid and then stir. The problem with this method is that, because powders are hygroscopic, during the pouring process, the surface layer of powder is first wetted by water. During this wetting process, water molecules connect the surface powder, reducing the gaps between adjacent powder molecules and increasing the interaction forces, thus forming powder clumps. The liquid cannot penetrate these clumps, preventing the powder from fully contacting the water and dissolving or emulsifying. Stirring continuously washes over the surface of the powder clumps, gradually eroding and dissolving them. This method only accelerates the mixing and dissolving process to a certain extent and does not solve the problem of powder clumping. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a mixing device to solve the problem in the prior art where, when powder raw materials are dissolved in water, the surface powder coats the inner powder to form powder clumps during the wetting process, preventing the liquid from entering the powder clumps and causing the powder to fail to fully contact the water and dissolve or emulsify.

[0005] To achieve the above and other related objectives, the present invention provides a mixing device, comprising:

[0006] The liquid feeding section and the powder feeding section are provided. The powder feeding section includes a base, a baffle plate, a pneumatic pipe, a shaft, a first elastic element, and a second elastic element.

[0007] The base is provided with an interconnected discharge channel and a feed channel. The pneumatic pipe is fixedly installed in the discharge channel and sealed at one end near the connection between the feed channel and the discharge channel. The other end of the pneumatic pipe is open and opposite to the discharge direction. A one-way air hole is provided at the sealed end of the pneumatic pipe and the air passage direction is towards the discharge port.

[0008] The shaft is aligned with the axis of the discharge channel and slidably connected to the sealing end of the pneumatic pipe. A sealing disc, a left limiting disc, and a right limiting disc are sequentially arranged on the shaft along one side of the opening of the pneumatic pipe. The sealing disc and the inner wall of the pneumatic pipe form a piston structure.

[0009] The baffle is slidably connected between the left and right limiting discs on the shaft. The second elastic element is disposed between the left limiting disc and the baffle. The end of the baffle is provided with a power source that can push the baffle toward the discharge port.

[0010] The liquid feeding section forms a waterfall-like water curtain and flows through the discharge port of the discharge channel.

[0011] Optionally, the power source is a cam, the edge of the cam contacts the tail end of the stop plate, and the stop plate slides along the shaft according to the convex shape of the cam.

[0012] Optionally, it also includes a blowing device, which is disposed inside the discharge port of the discharge channel and includes a fan blade frame and a spiral fan blade. The fan blade frame is fixedly connected to the inner wall of the discharge channel, and the spiral fan blade is rotatably connected to the fan blade frame. The middle part of the spiral fan blade is connected to the shaft through a lead screw pair.

[0013] Optionally, it also includes a dispersing device disposed at the discharge port of the discharge channel. The dispersing device comprises two sets of sheet-like structures with intersecting angles, and the cross-section of the dispersing device is grid-like.

[0014] Optionally, the liquid feeding section includes a water outlet tank and a water flow plate. The water flow plate is connected to the water outlet of the water outlet tank and is arranged at an angle downward. The discharge port of the discharge channel faces the water flow surface of the water flow plate.

[0015] Optionally, multiple vertical partitions are spaced apart on the water flow surface of the water flow plate to form multiple independent water flow channels.

[0016] Optionally, it also includes an isolation ring, which is fixedly disposed at the discharge port of the discharge channel and extends beyond the end face of the base, and the outer end face of the isolation ring is in contact with and aligned with the partition plate.

[0017] Optionally, there are at least two powder feeding units distributed vertically along the water curtain of the liquid feeding unit, and the cams of each powder feeding unit are connected through the same drive shaft and driven by the same power source.

[0018] Optionally, the number of protrusions among the cams of the plurality of powder feeding sections may be different.

[0019] Optionally, it also includes a water collector and a housing, the water collector being disposed at the end of the water curtain of the liquid feeding section, and the housing accommodating the liquid feeding section and the powder feeding section and forming a sealed chamber.

[0020] As described above, the mixing device of the present invention has at least the following beneficial effects:

[0021] This device effectively prevents powdered solids from forming clumps when dissolving in a liquid, thus preventing further dissolution. Specifically, the device creates a water curtain by having the liquid to be dissolved flow down in a waterfall-like manner, while the powder to be dissolved is sprayed onto the water curtain in a suspended state. This increases the contact area between the powder particles and the liquid, accelerates the dissolution efficiency, improves the completeness of dissolution, and prevents the formation of insoluble powder clumps.

[0033] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0034] Please see Figures 1 to 10 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance.

Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0035] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0036] Please refer to this embodiment. Figure 1-4 This invention provides an embodiment of a mixing device. The device includes a liquid feeding section 2 and a powder feeding section 1. The powder feeding section 1 can be found in [reference needed]. Figure 3 and Figure 4 It includes a base 10, a baffle plate 11, a pneumatic pipe 12, a shaft 13, a first elastic element 14, and a second elastic element 15. The base 10 is provided with an interconnected discharge channel 101 and a feed channel 102, the connection being switched by the sliding of the baffle plate 11, specifically as follows... Figure 4As shown, the connection is cut off when the baffle plate 11 slides into the bottom of the feed channel 102. The air pressure pipe 12 is fixedly installed in the discharge channel 101 and is sealed at one end near the connection between the feed channel 102 and the discharge channel 101. The other end of the air pressure pipe 12 is open and opposite to the discharge direction. A one-way air hole 121 is provided at the sealed end of the air pressure pipe 12, and the air passage direction is towards the discharge port. Specifically, the discharge channel 101 extends horizontally through the base 10, and the feed channel 102 is set vertically and enters the discharge channel 101. Taking the connection part as the boundary, the left part of the discharge channel 101 is the discharge direction, and the right part is provided with the aforementioned air pressure pipe 12. The air pressure pipe 12 is tubular and closed on the left side. A one-way air hole is provided on the closed surface. A one-way air hole is a structure in which gas can only pass through in one direction. It is frequently used in squeeze-type beverage bottles and will not be described in detail here.

[0037] The shaft 13 coincides with the axis of the discharge channel 101 and is slidably connected to the sealing end of the pneumatic pipe 12. A sealing disc 131, a left limiting disc 132, and a right limiting disc 133 are sequentially arranged on the shaft 13 along one side of the opening of the pneumatic pipe 12. The sealing disc 131 forms a piston structure with the inner wall of the pneumatic pipe 12. When the shaft 13 drives the sealing disc 131 to move into the pneumatic pipe 12, the sealing disc 131 compresses the gas inside the pneumatic pipe 12. This gas enters the discharge channel 101 through the one-way air hole 121 inside the pneumatic pipe 12, blowing out the powder from the discharge channel 101.

[0038] The baffle plate 11 is slidably connected between the left limiting plate 132 and the right limiting plate 133 on the shaft 13. The second elastic element 15 is disposed between the left limiting plate 132 and the baffle plate 11. The end of the baffle plate 11 is provided with a power source that can push the baffle plate 11 toward the discharge port. During the sliding process of the baffle plate 11, it first compresses the second elastic element 15. During this process, the shaft 13 remains stationary, and the baffle plate 11 moves to the left and inserts into the bottom of the feed channel 102 to cut off the feed. As the baffle plate 11 continues to move to the left, the second elastic element 15 is compressed to its limit, and the baffle plate 11 will push the shaft to move to the left together. Once the shaft 13 moves to the left and enters the air pressure pipe 12 through the sealing plate 131, the gas in the air pressure pipe 12 forms pressure and breaks through the one-way air hole 121 to enter the discharge channel 101, blowing out the powder in the discharge channel 101.

[0039] The liquid feeding section 2 forms a waterfall-like water curtain and flows through the outlet of the discharge channel 101. The powder sprayed from the outlet of the discharge channel 101 is blown onto the water curtain. Through the contact between the surface liquid and the mist powder, the powder solid can be effectively prevented from forming clumps in the liquid, which would prevent the powder from dissolving further in the liquid.

[0040] To facilitate understanding of the core elements of this solution, its working process is briefly summarized as follows:

[0041] The arrangement of the liquid feeding unit 2 and the powder feeding unit 1 can be found in [reference]. Figure 1 and Figure 2 The outlet of the powder feeding section 1 is directly opposite the water curtain formed by the liquid feeding section 2;

[0042] In the initial state, such as Figure 5 As shown, the sealing disc 131 on the shaft 13 is located outside the air pressure pipe 12, and the sliding end of the baffle plate 11 is located on the right side of the limiting disc 133 on the shaft 13. The baffle plate 11 does not block the connection between the discharge channel 101 and the feed channel 102, and the powder in the feed channel 102 falls into the discharge channel 101.

[0043] When switching states, such as Figure 6 As shown, the baffle plate 11 moves to the left under the action of an external power source, the second elastic element 15 is compressed, and the baffle end of the baffle plate 11 inserts into the bottom of the feed channel 102 to cut off the communication relationship, thereby fixing the amount of powder.

[0044] When ejected, such as Figure 7 As shown, when the second elastic element 15 is compressed to its limit, the leftward movement of the baffle plate 11 will also drive the shaft 13 to move to the left, and the first elastic element 14 will be compressed by the sealing disc 131. Once the sealing disc 131 enters the air pressure pipe 12, the air pressure in the air pressure pipe 12 increases, causing the one-way air hole 121 to open, and the gas is blown out from the air pressure pipe 12 and blows the powder in the discharge channel 101 out and sprays it onto the water curtain for dissolution and mixing;

[0045] After the above actions are completed, the power source of the baffle plate 11 is deactivated. Under the action of the first elastic element 14 and the second elastic element 15, the shaft 13 and the baffle plate 11 are reset, the discharge channel 101 and the feed channel 102 are reconnected, and the powder in the feed channel 102 falls back into the discharge channel 101, returning to the initial state. Repeating the above process can provide a continuous dissolution and mixing effect.

[0046] Please refer to this embodiment. Figure 1 and Figure 10 The power source is a rotating cam 4. The edge of the cam 4 contacts the tail end of the baffle plate 11, which slides along the shaft 13 according to the shape of the protrusion 41 on the cam 4. Through the action of the protrusion 41 on the cam 4, the cam can complete one feeding action with each rotation. By controlling the rotation speed of the cam, the feeding rhythm can be controlled. Combined with the amount of powder sprayed from the discharge channel 101 in each rhythm and the water flow rate of the liquid feeding section 2 in each rhythm, the ratio of mixed and dissolved raw materials can be easily adjusted. When the ratio needs to be adjusted, only the rotation speed of the cam needs to be adjusted, without any modification to the device. This process can even be completed without stopping the machine, making it easy to operate.

[0047] Please refer to this embodiment. Figure 3 and Figure 4 It also includes a blowing device 5, which is located inside the discharge port of the discharge channel 101. The blowing device 5 includes a fan blade frame 50 and a spiral fan blade 51. The fan blade frame 50 is fixedly connected to the inner wall of the discharge channel 101, and the spiral fan blade 51 is rotatably connected to the fan blade frame 50. The middle part of the spiral fan blade 51 is connected to the shaft 13 through a lead screw pair. The lead screw pair can convert rotational motion and linear motion, converting the linear motion of the shaft 13 into the rotational motion of the spiral fan blade 51. During the movement of the shaft 13, in addition to the sealing disc 131 cooperating with the air pressure pipe 12 to form the blowing air pressure, the shaft 13 inserting into the spiral fan blade 51 can also make the spiral fan blade 51 rotate, further increasing the blowing air pressure, allowing the powder to hit the waterfall-like water curtain formed by the liquid feeding section 2 at a faster speed, further enhancing the dissolution effect.

[0048] Furthermore, such as Figure 3 and Figure 4 It also includes a dispersing device 6, which is located at the outlet of the discharge channel 101. The dispersing device 6 comprises two sets of intersecting plate-like structures, and its cross-section is grid-like. When the spiral fan blades 51 and the sealing disc 131 operate, the airflow they generate blows the powder out of the discharge channel 101 as a whole. Once the dispersing device 6 is installed, it divides the original single air duct into numerous isolated small air ducts, which can enhance the dispersion effect of the sprayed powder and prevent large clumps or lumps of powder from affecting the dissolution effect of the powder on the water curtain.

[0049] Please refer to this embodiment. Figure 1 and Figure 8 The liquid feeding unit 2 includes a water outlet 20 and a water flow plate 21. The water flow plate 21 is connected to the water outlet of the water outlet 20 and is arranged at an angle downwards. The discharge outlet of the discharge channel 101 faces the water flow surface of the water flow plate 21, and baffles are provided on both sides of the water flow plate. Because the water flow plate 21 is arranged at an angle, it supports the water flow. The water flow is not free-falling downwards, which can prevent the water below the water curtain from pooling together and changing from a waterfall shape at the top to a stream shape at the bottom, thereby reducing the effective surface area and reducing the dissolution efficiency and quality of the powder and liquid.

[0050] Furthermore, multiple vertical partition plates 210 are spaced apart on the water flow surface of the water flow plate 21 to form multiple independent water flow channels. The independent water flow channels can further solve the problem that the water at the bottom of the water curtain may converge into streams in the above scheme.

[0051] Please refer to this embodiment. Figure 1 and Figure 9It also includes an isolation ring 3, which is fixedly installed at the discharge port of the discharge channel 101 and extends beyond the end face of the base 10. The outer end face of the isolation ring 3 is in contact with and aligned with the partition plate 210. If a dispersing device 6 is used, the outer shell of the dispersing device 6 can also be used as the isolation ring. The outer end face of the isolation ring presses against the partition plate 210. When the powder is sprayed from the isolation ring 3, all the powder will be sprayed into the flow channel between the partition plates 210, and then move up or down along the flow channel and fully contact the liquid in the flow channel. The contact and alignment between the isolation ring and the partition plate 210 can prevent the sprayed powder from escaping laterally into the air through the gap between them and thus failing to come into contact with and dissolve in the liquid.

[0052] Please refer to this embodiment. Figure 1 and Figure 2 There are at least two powder feeding sections 1, which are vertically distributed along the water curtain of the liquid feeding section 2. The cams 4 of each powder feeding section 1 are connected through the same drive shaft and driven by the same power source. In this embodiment, multiple powder raw materials and liquids can be mixed and dissolved with only one power source, which can reduce the power consumption of the device and improve the applicability of the device.

[0053] Furthermore, the number of protrusions 41 among the multiple powder feeding sections 1 differs. Originally driven by the same power source, the multiple cams 4 rotate at the same speed. By adjusting the number of protrusions 41 on the cams 4, the working rhythm of each powder feeding section 1 relative to the others can be easily adjusted, thereby achieving adjustment of the feeding ratio of different powder raw materials. For example... Figure 1 In the middle, among the three powder feeding sections 1 from top to bottom, the powder feeding ratio is 1:5:3.

[0054] Please refer to this embodiment. Figure 2 The system also includes a water collector 7 and a housing 8. The water collector 7 is located at the end of the water curtain of the liquid feeding section 2, and the housing 8 houses the liquid feeding section 2 and the powder feeding section 1, forming a sealed chamber. A stirring structure can be installed in the water collector 7 for secondary stirring, further improving the mixing and dissolving effect. The housing 8 prevents impurities from entering the mixture and also prevents leakage for some special raw materials. The top of the housing 8 has three powder inlets and one liquid inlet for adding the mixing raw materials. The bottom of the water collector 7 has a liquid outlet to guide the finished mixed liquid out of the housing 8.

[0055] In summary, the present invention effectively overcomes the various shortcomings of the prior art, produces beneficial technical effects, and has made significant progress.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
