Technical Field

[0001] The invention belongs to the technical field of mixing equipment, and particularly relates to a device for preparing a povidone-iodine solution. Background Art

[0002] Povidone-iodine solution is a broad-spectrum, powerful bactericidal disinfectant. Currently, most solutions are prepared by mixing powder and solvent, that is, mixing povidone-iodine powder and base liquid into a povidone-iodine solution of a certain concentration.

[0003] Since povidone-iodine powder itself has a certain surface tension when entering the base liquid, it is easy to form clumps and granules in the base liquid, and even fail to dissolve fully after processing. As a result, existing equipment requires longer stirring time to break up the dissolved powder, which makes it difficult to meet the needs of efficient and high-quality mixing processing.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1: Figure 1-4 As shown, a povidone-iodine solution preparation device includes a tank body 1 and a control panel. The upper and lower ends of the tank body 1 are respectively provided with a feed port 11 and a discharge port 12. A stirring mechanism is provided in the tank body 1, and a residue filtering mechanism is provided between the tank body 1 and the stirring mechanism.

[0025] The filter residue mechanism includes a side filter residue assembly, and the number of side filter residue assemblies is several and they are equidistantly arranged along the height direction of the stirring mechanism. The side filter residue assembly includes a side filter residue frame 2, a slag pressing brush 21 and a first transmission device. The side filter residue frame is fixed to the stirring mechanism, and the slag pressing brush 21 is slidably arranged in the side filter residue frame 2. The first transmission device is arranged in the side filter residue frame 2 and is transmission-connected to the slag pressing brush 21. A shift rod matching the first transmission device is provided in the tank body 1.

[0026] When preparing the povidone iodine solution, the base liquid is first injected into the tank body 1 through the feed port 11 for preparation, and then the stirring mechanism is turned on through the control panel to stir the solution, and finally the povidone iodine powder is input into the tank body 1 through the feed port 11 to be mixed with the base liquid, thereby preparing a povidone iodine solution with a certain concentration ratio. During the stirring and mixing process of the base liquid and the powder, the side filter residue component will capture some of the powder that has agglomerated or not dispersed in time, so that the side filter residue frame 2 attaches such powder to its surface through the rotational force, and the first transmission device drives the slag pressing brush 21 synchronously with the motion trajectory of the stirring mechanism, so that it circulates back and forth along the length direction of the side filter residue frame 2, thereby breaking up the attached agglomerated powder, so that it can be mixed with the base liquid more quickly and effectively, avoiding the increase in mixing time and the appearance of sediment particles in the later stage. Compared with the conventional mixing and stirring processing method, the prepared povidone iodine solution has a shorter processing time and a higher dissolution and mixing degree.

[0027] The stirring mechanism includes a motor 3, a rotating shaft 31 and several stirring blades 32. The motor 3 is fixed at the upper end of the tank body 1. The rotating shaft 31 is rotatably arranged in the tank body 1 and is transmission-connected to the output shaft of the motor 3. The several stirring blades 32 are evenly arranged on the side of the rotating shaft 31.

[0028] The first transmission device includes a rotating rod 4 and a fan head 41. The rotating rod 4 is rotatably connected to the side of the rotating shaft 31 and is located in the side filter residue frame 2. The fan head 41 is connected to the other end of the rotating shaft 31 and corresponds to the position of the circumferential trajectory of the shifting rod. A guide groove 42 is opened on the side of the rotating rod 4. The guide groove 42 is connected around the head and tail of the rotating rod 4 and the two end points are respectively located at the opposite ends of the rotating rod 4. The slag pressing brush 21 is provided with a transmission head 43 that is engaged and slides with the guide groove 42.

[0029] The fan head 41 is composed of a plurality of fan blades, and the fan blades are arranged at an angle relative to the rotating shaft 31.

[0030] When the side filter residue assembly moves synchronously with the rotating shaft 31, the fan head 41 in the first transmission device will gradually approach the shift rod until the fan head 41 abuts against the shift rod. The fan head 41 is blocked and rotates, thereby causing the rotating rod 4 to rotate synchronously. Since the guide groove 42 opened on the side of the rotating rod 4 is engaged with the transmission head 43 on the slag pressing brush 21, the slag pressing brush 21 will move in the side filter residue frame 2 under the action of the rotational force of the rotating rod 4, thereby breaking up the lumped powder captured on the side filter residue frame 2 and promoting dissolution and mixing.

[0031] Example 2: Figure 2-3As shown, a further improvement based on Example 1, an upper filter residue assembly is further provided on the upper side of the rotating shaft 31, the upper filter residue assembly includes a filter residue plate 5, a slag press, a spring 51 and a guide, a mounting groove is opened in the middle of the rotating shaft 31, the filter residue plate 5 is concentrically slidably connected to the rotating shaft 31 and the middle part extends into the mounting groove, the spring 51 is arranged between the filter residue plate 5 and the upper inner wall of the mounting groove, the slag press is connected to the tank body 1 for sliding up and down through the bracket and is concentrically arranged with the rotating shaft 31, and the guide is arranged between the tank body 1 and the filter residue plate 5.

[0032] The slag press includes a counterweight ring 6 and a plurality of crushing rods 61 . The plurality of crushing rods 61 are evenly arranged on the counterweight ring 6 . The counterweight ring 6 is slidably connected to the rotating shaft 31 and fixedly connected to the bracket.

[0033] The guide includes a lifting head 7 and a guide plate 71. The guide plate 71 is fixedly connected to the inner wall of the tank body 1 through a bracket. The guide plate 71 is a spiral structure as a whole and the axis of the rotating shaft 31 is the guiding axis. The guide plate 71 is an ascending spiral relative to the rotation direction of the rotating shaft 31. The lifting head 7 is fixedly arranged on the side of the filter residue plate 5 and corresponds to the position of the guide plate 71.

[0034] Furthermore, since the povidone-iodine powder is mixed and initially added, a vortex of the base liquid is formed by the unidirectional rotation of the base liquid, which gathers toward the middle of the base liquid, i.e., the middle of the rotating shaft 31. A portion of the foam and powder will be difficult to mix into the base liquid. Therefore, during the mixing process of the stirring mechanism, the lifting head 7 on the side of the filter plate 5 and the guide plate 71 cooperate to enable the lifting head 7 of the filter plate 5 to drive the entire filter plate 5 to lift and slide upward along the guide plate 71 until it is separated from the guide plate 71. In the process of rising, due to the filter residue The plate 5 itself synchronizes with the rotating shaft 31 to rotate, while the slag press is stationary relative to the filter plate 5. Therefore, under the action of relative motion, the filter plate 5 will capture the powder, foam, etc. gathered in the middle of the base liquid, and then cooperate with the crushing rod 61 to break and crush them, and finally reset and fall back into the base liquid for mixing. This can effectively improve the mixing effect and reduce the mixing time. The setting of the spring 51 can ensure that the filter plate 5 falls back stably. Of course, the natural fall of gravity can also be adopted. The counterweight ring 6 of the slag press adopts natural fall.

[0035] Example 3: Figure 2-3As shown, a further improvement based on Example 1, the rotating shaft 31 is further provided with a pumping assembly, the pumping assembly includes a piston 8 and a connecting rod 81, a suction chamber 82 is opened in the middle of the rotating shaft 31, the piston 8 is slidingly sealed in the suction chamber 82, the connecting rod 81 is concentrically fixed to the piston 8 and slides out of the suction chamber 82 to be connected to the filter plate 5, a liquid path 83 connected to the lower end of the suction chamber 82 is opened in the middle of the connecting rod 81, a number of nozzles are provided on the side of the rolling rod 61, and the number of nozzles are connected to the liquid path 83 through a hose, a number of one-way liquid inlet valves connected to the lower space of the suction chamber 82 are opened on the side of the rotating shaft 31, and the liquid path 83 is provided with a one-way liquid discharge valve.

[0036] Furthermore, in order to prevent some agglomerated powder from adhering to the surface of the filter plate 5 after crushing and being unable to be separated and dissolved in time, when the filter plate 5 moves upward, it will drive the connecting rod 81 and the piston 8 to move upward synchronously in the suction chamber 82, and then extract the base liquid through the one-way liquid inlet valve set on the side of the rotating shaft 31. When it falls back, this part of the base liquid is squeezed out by pressure, and is connected through the liquid path 83 and the hose, and finally sprayed out through the nozzle, so as to achieve the purpose of using the pressure of the base liquid injection to remove and dissolve the attached powder. At the same time, the one-way liquid inlet valve can be evenly set at different heights of the rotating shaft 31 to extract base liquid at different heights, which can further promote mixing.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may 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 one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
