DETAILED DESCRIPTION

[0042] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0043] Embodiment 1, as Figure 1 As shown, a mixing device for producing iodine tincture disinfectant comprises a mixing barrel 2, a feeding structure 1 is provided on the front and left sides of the outer surface of the mixing barrel 2, a steam heating structure 3 is provided on the right side of the outer surface of the mixing barrel 2 and extends through the outer surface to the inner cavity of the mixing barrel 2, a mixing structure 5 is provided on the inner cavity of the mixing barrel 2 and extends through the top wall of the inner cavity to the upper end of the mixing barrel 2, and a discharge pipe 4 is provided on the front side of the outer surface of the mixing barrel 2 and communicates with the inner cavity.

[0044] Specifically, to achieve batch and quantitative feeding functions, refer to Figure 2The feeding structure 1 includes a plurality of liquid storage tanks 11, and the upper ends of the plurality of liquid storage tanks 11 are fixedly connected with connecting pipes 12, and the plurality of connecting pipes 12 respectively penetrate the outer surface of the mixing barrel 2 and extend to the inner cavity of the mixing barrel 2. A water pump is installed inside the liquid storage tanks 11, and a powder delivery device 13 is fixedly installed on the front of the outer surface of the mixing barrel 2. The inner cavity of the powder delivery device 13 is divided into a plurality of storage cavities, and the plurality of storage cavities are connected with the inner cavity of the mixing barrel 2 through a feeder.

[0045] It should be noted that the liquid storage tank 11 is a conventional liquid storage device in the prior art, and the water pump inside it gives it the function of transporting liquid outward. In the present invention, it is mainly used to store deionized water, sodium lactate and nonylphenol polyoxyethylene ether. This structure has been widely used in the prior art. In the present invention, it is only used to realize the function, and its internal structure, operating principle, wiring, and control method are not described in detail.

[0046] Similarly, the above-mentioned powder feeding equipment 13 is also a conventional solid feeding equipment, which can quantitatively feed solid materials such as powders and granules to a predetermined position. In the present invention, it is mainly used for storing and feeding polyvinyl pyrrolidone, potassium dihydrogen phosphate and iodine. This structure has been widely used in the prior art. In the present invention, it is only used to realize its function, and its internal structure, operating principle, wiring, and control method are not described in detail.

[0047] During the operation of this embodiment, the materials are respectively put into each chamber divided by the mixing structure 5 through the action of the liquid storage tank 11 and the powder delivery device 13, and the required premixed solution is stirred by the action of the mixing structure 5 to promote its dissolution in the predetermined solution. At the same time, after the stirring reaches a predetermined time, the two premixed liquids are mixed together and further stirred to make them evenly mixed by the action of the mixing structure 5. At the same time, the steam heating structure 3 is used to heat them to speed up the mixing efficiency. Furthermore, after the heating and mixing are completed, the equipment is reversed again to send the last group of solutions into the mixed material, and fully stirred until the production is completed.

[0048] Embodiment 2: Based on Embodiment 1, this embodiment divides the interior of the mixing barrel 2 into different chambers by utilizing the separation effect of the isolation plate 54 and the bottom support plate 55, and at the same time utilizes the effect of the driving motor 51 and the bevel gear set 52 to drive the central driving component 53 to rotate, thereby utilizing the cooperation between the central driving component 53 and the three-state conversion component 56 to drive the three-state conversion component 56 to rotate inside the mixing barrel 2, thereby stirring the material fed into the feeding structure 1 evenly, promoting the dissolution of the ions inside the mixing barrel 2 into the deionized water or nonylphenol polyoxyethylene ether, thereby achieving the mixing of the materials;

[0049] At the same time, the steam generator 31 delivers high-temperature steam to the aeration head 33 through the connecting pipe 32. The high-temperature bubbles enter the chamber above the isolation plate 54 in the form of steam aeration, and the solution is heated by heat transfer between the bubbles and the solution. At the same time, the buoyancy generated by the rising of the bubbles and the impact force generated by the explosion of the bubbles can assist in stirring the solution and promote the zone fusion efficiency.

[0050] Specifically, to achieve mixing and stirring of the solution, refer to Figure 3 and Figure 4 The mixing structure 5 includes a bottom supporting plate 55 fixedly connected to the lower part of the inner cavity of the mixing barrel 2 and a driving motor 51 fixedly connected to the upper end of the mixing barrel 2. The upper side of the inner surface of the mixing barrel 2 is symmetrically fixedly connected with isolation plates 54. The upper ends of the two isolation plates 54 and the upper ends of the bottom supporting plate 55 are rotatably connected with stirring blades 57. The inner surfaces of the bottom supporting plate 55, the isolation plates 54 and the stirring blades 57 are slidably connected with a central driving component 53. The upper end of the central driving component 53 penetrates the inner cavity of the mixing barrel 2 and extends to the upper end of the mixing barrel 2 and is drivingly connected to a bevel gear set 52 fixedly connected to the upper end of the mixing barrel 2. The input gear of the bevel gear set 52 is drivingly connected to the output end of the driving motor 51. The bottom wall of the inner cavity of the mixing barrel 2 is fixedly connected to a three-state conversion component 56 rotatably connected to the central driving component 53.

[0051] The driving motor 51 drives the central driving component 53 to rotate through the bevel gear set 52, thereby utilizing the interaction between the central driving component 53 and the three-state conversion component 56 to stir the solutions in the chambers separated by each isolation plate 54 and the bottom support plate 55. At the same time, the state of the central driving component 53 is converted by the forward and reverse operation of the driving motor 51 and the cooperation of the three-state conversion component 56, thereby achieving the mixing of different solutions in sequence and reducing the transportation process.

[0052] Further, in order to achieve heating of the mixed solution and stirring of the auxiliary three-state conversion component 56, refer to Figure 3 and Figure 4 The steam heating structure 3 includes a steam generator 31 fixed to the right part of the outer surface of the mixing barrel 2 and a pressure relief valve 34 fixedly connected to the right part of the outer surface of the mixing barrel 2 and located above the lower isolation plate 54. The output end of the steam heating structure 3 penetrates the outer surface of the mixing barrel 2 and extends to the inner cavity of the mixing barrel 2 and is fixedly connected to a connecting pipe 2 32. A plurality of aeration heads 33 penetrating the inner cavity of the bottom support plate 55 and extending to the upper end of the bottom support plate 55 are fixedly distributed in an annular manner on the upper part of the outer surface of the connecting pipe 2 32.

[0053] The steam generator 31 provides high-temperature steam and sends the steam to the upper layer of the bottom support plate 55 through the dispersing effect of the aeration head 33. At this time, the steam is dispersed into fine bubbles by the aeration head 33. At this time, the contact area between the unit volume of steam and the solution is the largest, and the heat exchange efficiency is also the highest. The solution can be quickly heated during the floating process, and the floating of the bubbles and the stirring and breaking of the bubbles will exert a force on the solution, accelerate the freedom of ions in the solution, and improve the mixing efficiency of the solution.

[0054] It should be noted that the steam generator 31 is a conventional boiler, which is internally provided with a heater, a water tank, and a fan, and can boil water to generate steam, thereby using the fan to send the steam into the connecting pipe 2 32 and spray it out through the aeration head 33. This structure has been widely used in the prior art. In the present invention, it is only used to realize the function of producing high-temperature steam, and its internal structure, operating principle, wiring, and control method are not described in detail.

[0055] Embodiment three: based on embodiment two, this embodiment further utilizes the function of switching drive assembly 562 to maintain the height of central axis 531 during the operation of driving motor 51, and at the same time, the height of central axis 531 can be switched by the cooperation of reverse operation of driving motor 51 and switching drive assembly 562. Through the difference in height of central axis 531, liquid outlet hole three 535 can be driven to connect with liquid outlet hole two 5334 and liquid outlet hole one 5333 in sequence, and the upper premixed liquid is added into the iodine-nonylphenol polyoxyethylene ether mixed liquid below in batches by the function of connecting hole two 537, connecting hole one 536 and connecting pipe 5336, and the production of iodine tincture solution is realized by continuous stirring and heating, without the need for frequent transportation between multiple devices, reducing the pollution of the mixed solution by the external environment, improving the quality of the prepared iodine tincture solution, and also reducing manual operation and the influence of manual work on production quality.

[0056] Specifically, in order to achieve the action of the three-state conversion component 56, each group of premixed solutions is mixed in sequence, see Figure 5 , Figure 6 , Figure 7 and Figure 8The central driving assembly 53 includes a central shaft 531 which is slidably connected to the inner surface of the output gear of the bevel gear set 52. The upper portion of the outer surface of the central shaft 531 is symmetrically provided with transmission grooves 532 which are slidably connected to the stirring blades 57 at the positions corresponding to the stirring blades 57. The upper portion of the outer surface of the central shaft 531 is located on the upper side of the two isolation plates 54 and is respectively provided with a second connecting hole 537 and a first connecting hole 536 which penetrate the central shaft 531. The opening directions of the first connecting hole 536 and the second connecting hole 537 are perpendicular to each other. The lower portion of the outer surface of the central shaft 531 is provided with a cross groove 534 which is connected to its inner cavity. The inner surface of the cross groove 534 is connected to the inner surface of the central shaft 531. The surfaces are slidably connected with a linkage component 533 that is rotatably connected to the three-state conversion component 56. The lower part of the inner surface of the central shaft 531 is slidably connected to the three-state conversion component 56. The lower end of the central shaft 531 is fixedly connected with a limit spring 538 sleeved on the outer surface of the three-state conversion component 56. The lower end of the limit spring 538 is rotatably connected to the lower part of the inner cavity of the mixing barrel 2 through a sliding plate. The part of the central shaft 531 located below the lower isolation plate 54 is annularly distributed with four liquid outlet holes 535 connected to its inner cavity. The distance between the connecting hole 2 537 and the isolation plate 54 is half of the descending stroke of the central shaft 531 relative to the distance between the connecting hole 1 536 and the isolation plate 54.

[0057] The central shaft 531 is slidably connected to the inner surface of the output gear of the bevel gear set 52, thereby achieving transmission with the bevel gear set 52 during the up and down movement of the central shaft 531, thereby following the rotation of the bevel gear set 52 and driving the stirring blades 57 to rotate, thereby continuously stirring the solution. In addition, the stirring blades 57 are installed on the upper part of the isolation plate 54 or the bottom support plate 55, and will not move with the up and down movement of the central drive assembly 53, but will slide in the transmission groove 532, thereby ensuring the transmission effect.

[0058] The cross groove 534 is used to install the linkage component 533, and it can also enable the linkage component 533 to contact the bottom support plate 55 below, thereby realizing state switching when the vertical position of the central axis 531 changes. The limit spring 538 is used to pull the position of the central axis 531 to change with the three-state conversion component 56, and the liquid outlet hole three 535 can be connected with the connecting hole two 537 and the connecting hole one 536 in sequence through the linkage component 533.

[0059] Further, in order to realize the coordination of the action of the three-state conversion component 56 to connect different chambers in sequence, refer to Figure 6 , Figure 7 and Fig. 9The linkage component 533 includes a sliding column 5332 which is slidably connected to the inner surface of the central axis 531. The outer surface of the sliding column 5332 is annularly distributed and fixedly connected with a plurality of arc plates 5331 which are slidably connected to the inner surface of the cross groove 534. The lower end of the arc plate 5331 is tightly attached to the upper end of the bottom support plate 55. The upper end of the sliding column 5332 is fixedly connected with a shielding tube 5335 which is slidably connected to the inner surface of the central axis 531.

[0060] The arc plate 5331 is in contact with the top of the bottom support plate 55. When the position of the central axis 531 changes, the arc plate 5331 will block the liquid outlet hole 1 5333 from following the position change of the central axis 531. At this time, the relative position of the liquid outlet hole 1 5333 remains unchanged, but the central axis 531 is switched to the next predetermined position. Therefore, the height difference can be used to realize the connection between the liquid outlet hole 3 535 and the connecting hole 1 536, and the liquid outlet hole 3 535 and the connecting hole 2 537 in sequence.

[0061] Further, in order to guide the solutions in each chamber to flow downward to mix them, refer to Figure 6 , Figure 7 and Fig. 9 The linkage component 533 also includes a second liquid outlet hole 5334 and a first liquid outlet hole 5333 symmetrically opened on the outer surface of the sliding column 5332. The second liquid outlet hole 5334 and the first liquid outlet hole 5333 are both located directly below the corresponding third liquid outlet hole 535. The upper ends of the second liquid outlet hole 5334 and the first liquid outlet hole 5333 are fixedly connected with a connecting tube 5336 located on the inner side of the shielding tube 5335. The water inlet of the connecting tube 5336 connected with the second liquid outlet hole 5334 is located at the lower side of the connecting hole 1 536, and the water inlet of the connecting tube 5336 connected with the first liquid outlet hole 5333 is located at the lower side of the connecting hole 2 537.

[0062] The second liquid outlet hole 5334 corresponds to the position of the first liquid outlet hole 536 through the connecting tube 5336. When the central axis 531 drops once, the second liquid outlet hole 5334 is connected to the third liquid outlet hole 535, and the connecting tube 5336 on the upper part of the second liquid outlet hole 5334 is connected to the first liquid outlet hole 536. At this time, the solution B in the chamber where the first liquid outlet hole 536 is located will enter the solution C below and be heated and mixed.

[0063] Liquid outlet hole 1 5333 corresponds to the position of connecting hole 2 537 through connecting tube 5336. When the central axis 531 drops twice, liquid outlet hole 1 5333 is connected with liquid outlet hole 3 535, and connecting tube 5336 at the upper part of liquid outlet hole 1 5333 is connected with connecting hole 2 537. Solution A in the chamber where connecting hole 2 537 is located will flow downward into the upper part of the bottom support plate 55 and continue to be mixed.

[0064] Further, in order to realize the driving of the linkage component 533 to switch to different heights during the mixing process, refer to Fig. 9The three-state conversion component 56 includes a spring slide 561 rotatably connected to the lower end of the sliding column 5332, and the end of the spring slide 561 away from the sliding column 5332 is rotatably connected to a switching drive component 562 fixedly connected to the bottom wall of the inner cavity of the mixing barrel 2, the outer surface of the switching drive component 562 is slidably connected to the inner surface of the central shaft 531, and the lower part of the inner surface of the central shaft 531 is fixedly connected to a limiting roller 563 slidably connected to the inner surface of the switching drive component 562.

[0065] The switching drive assembly 562 is used to limit the position of the linkage component 533 and pull the linkage component 533 to keep it in contact with the top of the bottom support plate 55.

[0066] The spring slide 561 is fixed to the central shaft 531 and is used to drive the central shaft 531 to follow the operation of the switching drive assembly 562 to achieve height switching.

[0067] Further, in order to drive the central axis 531 to switch to different heights by cooperating with the switching driving assembly 562 and the limiting roller 563, thereby realizing the function of continuous production, refer to Fig.10 , Fig.11 and Fig.12 The switching drive assembly 562 includes a support shaft 5621, and three horizontal slide grooves 5625 are sequentially opened on the outer surface of the support shaft 5621 from top to bottom. An inclined slide groove 1 5622 connecting the two horizontal slide grooves 5625 located at the upper and middle parts is opened between the two horizontal slide grooves 5625 located at the lower and middle parts. An inclined slide groove 2 5624 connecting the two is opened between the two horizontal slide grooves 5625 located at the lower and middle parts. The spiral direction of the inclined slide groove 2 5624 is opposite to that of the inclined slide groove 1 5622. The upper part of the inner surface of the horizontal slide groove 5625 located at the lower part is opened with an inclined slide groove 3 5626 connected to the horizontal slide groove 5625 located at the upper part. The inclined slide groove 3 5626 is connected to the inclined slide groove 5626. The spiral directions of groove two 5624 are opposite, and the upper sides of the paths of inclined slide groove two 5624 and inclined slide groove one 5622 are rotatably connected with normally open flap one 5623. Normally, the normally open flap one 5623 is in an inclined state, and the inclined direction is the same as the current rotation direction. The inclined slide groove three 5626 is rotatably connected with the normally closed flap 5628 at the connection with the middle horizontal slide groove 5625 and the upper horizontal slide groove 5625. The normally closed flap 5628 is flush with the path of the adjacent horizontal slide groove 5625 under normal circumstances. The lower part of the path of inclined slide groove three 5626 is rotatably connected with the normally open flap two 5627 that fits with the bottom wall of the inner surface of the lower horizontal slide groove 5625.

[0068] First, when the driving motor 51 is running in the forward direction, the spring slide 561 will be in the uppermost horizontal slide groove 5625. At this time, the upper liquid outlet hole 3 535 is blocked by the outer surface of the sliding column 5332 and is not connected with the upper chamber. The chamber where the liquid outlet hole 3 535 is located is used to prepare solution C. When the driving motor 51 is reversed for the first time, the spring slide 561 is blocked by the normally open flap 1 5623, and thus enters the middle horizontal slide groove 5625 along the inclined slide groove 1 5622. At this time, the central axis 531 drops once, and the liquid outlet hole 3 535 is connected with the connecting hole 1 536 through the linkage component 533, and the switching drive component 562 continues to slide in the middle horizontal slide groove 5625;

[0069] When the driving motor 51 rotates forward for the second time, the switching driving component 562 is blocked by the normally open flap 1 5623 in the middle and enters the lower horizontal slide 5625 along the inclined slide 2 5624. At this time, the central axis 531 descends for the second time, the liquid outlet hole 3 535 is separated from the liquid outlet hole 2 5334, and the connecting tube 5336 connected with the liquid outlet hole 1 5333 is separated from the connecting hole 1 536 and connected with the connecting hole 2 537. The solution A in the chamber where the connecting hole 2 537 is located passes through the connecting hole 2 537, the connecting tube 5336, the liquid outlet hole 1 5333, and the liquid outlet hole 3 535 into the solution on the upper side of the bottom support plate 55, and is continuously stirred and mixed by the stirring blade 57.

[0070] When the driving motor 51 reverses for the second time, it will be blocked by the normally open flap 2 5627. At this time, the switching driving component 562 will move up along the inclined slide groove 3 5626. At this time, the normally closed flap 5628 will be pushed open, guiding the switching driving component 562 to move upward along the path of the inclined slide groove 3 5626 until it returns to the upper horizontal slide groove 5625, realizing automatic resetting, and turning the external valve to use the discharge pipe 4 to discharge the mixed solution.

[0075] Solution C: Under normal temperature and pressure, add iodine to nonylphenol polyoxyethylene ether (TX-10), stir for 2.5-4 hours, then add solution B, stir for 1-2 hours to obtain solution C.

[0076] S2, mixing process: put solution C into the mixing barrel 2; heat it through the steam heating structure 3, the temperature range is 85-90°C, and stirring is maintained at the same time. The heating time is controlled within 120-150 minutes to promote the full reaction of iodine and surfactant to form a complex; gradually add solution A to the heated solution C, and continue stirring for 6-8 hours to ensure uniform mixing of the two solutions.

[0077] S3. Post-processing and quality control: Cool the mixed solution to room temperature and perform precision filtering through a filter to remove insoluble impurities; perform quality inspection, including but not limited to appearance inspection, pH value determination, and effective iodine content determination.

[0078] Compared with the conventional direct mixing method in the prior art, the premixing adopted in S1 can ensure that sodium lactate and potassium dihydrogen phosphate are fully dissolved in deionized water to form a uniform solution A, which is helpful for subsequent mixing with iodine and nonylphenol polyoxyethylene ether, avoiding the problem of uneven dissolution that may occur during direct mixing, and at the same time can reduce the volatilization and precipitation of iodine and improve the stability of the iodine solution.

[0079] Heating the solution in S2 can promote the full reaction of iodine and surfactant to form a complex. The temperature range can ensure the effective reaction of iodine and surfactant. Heating by passing steam can evenly transfer heat energy, which helps to improve reaction efficiency and product quality.
