Description

Technical Field

[0001] The utility model relates to the technical field of PHMB processing, in particular to a PHMB production mixing and stirring device. Background Art

[0002] PHMB is the abbreviation of polymer biocide. It is a commonly used bactericide and preservative, often used in medical, disinfection and personal care products. PHMB needs to be mixed with diluent before normal use. Mixing and stirring can help ensure the uniformity and stability of PHMB in the final product, thereby ensuring the effectiveness and safety of the product. In addition, mixing and stirring also helps to fully mix PHMB with other ingredients to obtain the desired formula and performance;

[0003] Most of the PHMB stirring and mixing devices in the prior art pour the diluent and PHMB into the stirring barrel uniformly for uniform stirring and mixing, which makes it difficult to completely mix the internal components, resulting in the appearance of lumps or uneven distribution.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a PHMB production mixing and stirring device, which utilizes a feeding mechanism to distribute the diluent and PHMB into a stirring barrel, thereby forming a separation between the pre-stirring and uniform stirring areas of the PHMB, and is matched with a synchronous wheel and the first gear, the second gear and the spring inside the screw rod to avoid possible motion interference, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a PHMB production mixing and stirring device, comprising a mixing barrel, a transition box is fixed to the top outer layer of the mixing barrel, a PHMB storage box is fixed to one side of the upper surface of the mixing barrel, a diluent storage box is fixed to one side of the upper surface of the transition box, and a bracket is fixed to the bottom of the transition box, and a feeding mechanism is installed inside the diluent storage box and the PHMB storage box;

[0007] The interior of the mixing barrel is rotatably connected to a rotating shaft, a plurality of stirring blades are equidistantly fixed to the outer layer of the rotating shaft, and two curved rods are symmetrically fixed to both sides of the bottom end of the rotating shaft, a plurality of scrapers are equidistantly fixed to the bottom and sides of the curved rods, a discharge port is fixed at the bottom of the mixing barrel at a position corresponding to the rotating shaft, and the discharge port penetrates through and extends to the outside of the mixing barrel, and two airtight valves are symmetrically fixed to both sides of the discharge port.

[0008] Furthermore, the feeding mechanism includes two screw rods which are rotatably connected to the inside of the diluent storage box and the PHMB storage box respectively, the outer layer of the screw rod is sleeved with a pressure plate, and two limit sliders are symmetrically fixed on both sides of the pressure plate, and limit grooves are provided at the positions of the limit sliders corresponding to the inside of the diluent storage box and the PHMB storage box.

[0009] Furthermore, a fixed plate is commonly fixed to the top of the dilution liquid storage box and the PHMB storage box, and synchronous wheels are rotatably connected to the upper surface of the fixed plate at the positions corresponding to the screw rod and the rotating shaft, and the three synchronous wheels are rotatably connected to each other through a synchronous belt, and a motor is fixed to the top of one of the synchronous wheels, and the tops of the screw rod and the rotating shaft pass through the fixed plate and are fixed to the bottom of the synchronous wheel.

[0010] Furthermore, a plurality of first tooth blocks are equidistantly fixed at positions inside the synchronous wheel corresponding to the top ends of the screw rods, two notches are symmetrically provided inside the two sides of the screw rods, a spring is fixed inside the notches, a second tooth block penetrating through and extending to the outside of the notches is fixed at one end of the spring, and the second tooth block is adapted to the first tooth block.

[0011] Furthermore, the inner bottom layer of the transition box is inclined with respect to the horizontal line, and a plurality of diversion pipes penetrating through and extending into the mixing barrel are equidistantly fixed inside the transition box, and a plurality of nozzles are equidistantly fixed at the bottom of the diversion pipes.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a feeding mechanism, which drives the screw and the rotating shaft to rotate synchronously through the motor, the synchronous belt and the synchronous wheel, and the pressing plate is driven to descend by the rotation of the screw, so that PHMB and the diluent are discharged into the mixing barrel and the transition box respectively, and the PHMB is pre-mixed to avoid the formation of lumps. When the two solutions are completely discharged, the diluent is sprayed into the mixing barrel by the nozzle, so as to be more evenly dispersed in the PHMB, which is conducive to mixing and dissolving.

[0014] 2. In the utility model, after the two solutions are completely discharged, the motor continues to work, driving the rotating shaft and the screw to rotate, and the rotating shaft drives the stirring blade to mix and dissolve PHMB and the diluent. At this time, the pressure plate can no longer move downward, resulting in the screw being unable to rotate. When the synchronous wheel continues to rotate, the first tooth block presses the second tooth block. Because the screw cannot rotate, the second tooth block is pressed and moves into the groove, and cooperates with the spring to reset. In this way, without affecting the rotation of the rotating shaft, motion interference is avoided, and the diluent and PHMB are effectively distributed and stirred, which is more conducive to overall mixing.

[0015] In summary, the utility model utilizes a feeding mechanism to discharge the diluent and PHMB into the mixing barrel in steps, first pre-stirs the PHMB to avoid the formation of lumps, and then sprays the diluent to form a better stirring and dissolving effect, and cooperates with the two gear blocks and the spring between the synchronous wheel and the screw rod to ensure that even if the pressure plate cannot move, it will not interfere with the stirring work.

DETAILED DESCRIPTION

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] This embodiment aims to address the problem that most PHMB stirring and mixing devices in the prior art pour the diluent and PHMB into the stirring barrel uniformly for uniform stirring and mixing, which makes it difficult to completely mix the internal components, resulting in the formation of lumps or uneven distribution.

[0027] like Figure 1-6 As shown, a PHMB production mixing and stirring device comprises a mixing barrel 1, a transition box 2 is fixed to the top outer layer of the mixing barrel 1, and a PHMB storage box 8 is fixed to one side of the upper surface of the mixing barrel 1, a diluent storage box 3 is fixed to one side of the upper surface of the transition box 2, a feed port and a discharge port are fixed to the outer layer and bottom of the diluent storage box 3 and the PHMB storage box 8, and an airtight valve 10 is fixed to the outer layer of the feed port and the discharge port to ensure the airtight state of the overall internal structure, and a bracket 11 is fixed to the bottom of the transition box 2, and a feeding mechanism 18 is installed inside the diluent storage box 3 and the PHMB storage box 8;

[0028] The feeding mechanism 18 includes two screw rods 19 which are rotatably connected to the inside of the diluent storage box 3 and the PHMB storage box 8 respectively. The outer layer of the screw rod 19 is sleeved with a pressure plate 26. Two limit sliders 21 are symmetrically fixed on both sides of the pressure plate 26. The inside of the diluent storage box 3 and the PHMB storage box 8 are provided with limit grooves 20 at positions corresponding to the limit sliders 21.

[0029] A fixed plate 7 is fixed to the top of the diluent storage box 3 and the PHMB storage box 8. The upper surface of the fixed plate 7 is rotatably connected to a synchronous wheel 4 at the position corresponding to the screw rod 19 and the rotating shaft 9. The three synchronous wheels 4 are rotatably connected through a synchronous belt 5. A motor 6 is fixed to the top of one of the synchronous wheels 4. The tops of the screw rod 19 and the rotating shaft 9 penetrate the fixed plate 7 and are fixed to the bottom of the synchronous wheel 4.

[0030] The inside of the mixing barrel 1 is rotatably connected to a rotating shaft 9, and a plurality of stirring blades 17 are equidistantly fixed on the outer layer of the rotating shaft 9. The stirring blades 17 are in a spiral auger structure, so as to drive the liquid to form a lifting effect during the stirring process, which is more conducive to the dispersion of the solvent. Two curved rods 12 are symmetrically fixed on both sides of the bottom end of the rotating shaft 9, and a plurality of scrapers 16 are equidistantly fixed on the bottom and side of the curved rod 12. A discharge port 15 that penetrates and extends to the outside of the mixing barrel 1 is fixed at the position of the rotating shaft 9 at the bottom of the mixing barrel 1, and two airtight valves 10 are symmetrically fixed on both sides of the discharge port 15.

[0031] The bottom layer of the interior of the transition box 2 is inclined with respect to the horizontal line, and a number of diversion pipes 13 penetrating through and extending into the mixing barrel 1 are fixed equidistantly inside the transition box 2. A built-in pump is provided at the position of the diversion pipe 13 inside the transition box 2 to extract the dilution liquid and spray it out through the diversion pipe 13 to the nozzle 14. A number of nozzles 14 are fixed equidistantly at the bottom of the diversion pipe 13.

[0032] Pour an appropriate amount of diluent and PHMB into the diluent storage box 3 and the PHMB storage box 8, then start the motor 6 to cooperate with the synchronous wheel 4 and the synchronous belt 5 to drive the two screw rods 19 and the rotating shaft 9 to rotate, and the screw rods 19 inside the diluent storage box 3 and the PHMB storage box 8 rotate to drive the feeding mechanism 18 to rise and fall, so as to squeeze the PHMB and the diluent into the mixing barrel 1 and the transition box 2;

[0033] The synchronous wheel 4 rotates while driving the rotating shaft 9 to rotate, and the rotating shaft 9 drives the stirring blade 17 to rotate, and the stirring blade 17 pre-stirs the PHMB falling into the mixing barrel 1, and the rotating shaft 9 drives the curved rods 12 on both sides to rotate, and the curved rods 12 rotate and drive the scraper 16 to scrape the inner wall of the mixing barrel 1 to avoid adhesion;

[0034] When the two solutions are completely discharged into the mixing barrel 1 and the transition box 2, the PHMB is pre-mixed, and then the diluent is sprayed through the nozzle 14 to cooperate with the stirring effect of the stirring blade 17 to form a more uniform mixed dissolution.

[0035] Embodiment 2:

[0036] This embodiment aims to address the problem that most PHMB stirring and mixing devices in the prior art pour the diluent and PHMB into the stirring barrel uniformly for uniform stirring and mixing, which makes it difficult to completely mix the internal components, resulting in the formation of lumps or uneven distribution.

[0037] like Figure 7 As shown, the embodiment is a PHMB production mixing and stirring device, and a plurality of first tooth blocks 22 are fixed at equal intervals at the top position of the corresponding screw rod 19 inside the synchronous wheel 4, and two notches 23 are symmetrically opened inside the two sides of the screw rod 19, and a spring 24 is fixed inside the notch 23, and a second tooth block 25 that penetrates and extends to the outside of the notch 23 is fixed at one end of the spring 24, and the second tooth block 25 is adapted to the first tooth block 22, and the first tooth block 22 rotates to press the second tooth block 25, and the second tooth block 25 moves to the inside of the notch 23 with the pressure, and cooperates with the spring 24 to form a reset effect, so as to repeat the cycle and avoid interference with the stirring work.

[0038] When the two solutions are completely discharged from the diluent storage box 3 and the PHMB storage box 8, as the synchronous wheel 4 continues to rotate, the rotating shaft 9 and the screw rod 19 are driven to rotate continuously. At this time, the pressure plate 26 cannot continue to descend, and the screw rod 19 cannot rotate. The synchronous wheel 4 continues to rotate to drive the first gear block 22 to rotate. The rotation of the first gear block 22 presses the second gear block 25, and then moves to the inside of the notch 23, and cooperates with the spring 24 to form a reset effect, so as to repeat the cycle and avoid interference with the stirring work.

[0039] Working process and principle of this utility model:

[0040] Step 1: Pour an appropriate amount of diluent and PHMB into the diluent storage box 3 and the PHMB storage box 8, then start the motor 6 to cooperate with the synchronous wheel 4 and the synchronous belt 5 to drive the two screw rods 19 and the rotating shaft 9 to rotate, and the screw rod 19 inside the diluent storage box 3 and the PHMB storage box 8 rotates to drive the feeding mechanism 18 to rise and fall, so as to squeeze the PHMB and the diluent into the mixing barrel 1 and the transition box 2;

[0041] The synchronous wheel 4 rotates while driving the rotating shaft 9 to rotate, and the rotating shaft 9 drives the stirring blade 17 to rotate, and the stirring blade 17 pre-stirs the PHMB falling into the mixing barrel 1, and the rotating shaft 9 drives the curved rods 12 on both sides to rotate, and the curved rods 12 rotate and drive the scraper 16 to scrape the inner wall of the mixing barrel 1 to avoid adhesion;

[0042] When the two solutions are completely discharged into the mixing barrel 1 and the transition box 2, the PHMB is pre-mixed, and then the diluent is sprayed through the nozzle 14, so as to cooperate with the stirring effect of the stirring blade 17 to form a more uniform mixed dissolution;

[0043] Step 2: After the two solutions are completely discharged from the diluent storage box 3 and the PHMB storage box 8, as the synchronous wheel 4 continues to rotate, the rotating shaft 9 and the screw rod 19 are driven to rotate continuously. At this time, the pressure plate 26 cannot continue to descend, and the screw rod 19 cannot rotate. The synchronous wheel 4 continues to rotate to drive the first tooth block 22 to rotate. The rotation of the first tooth block 22 presses the second tooth block 25, and then moves to the inside of the notch 23, and cooperates with the spring 24 to form a reset effect, so as to repeat the cycle and avoid interference with the stirring work.

[0044] In summary, the feeding mechanism 18 is used to form a step-by-step feeding effect for the diluent and PHMB, thereby improving the overall mixing and stirring effect. In conjunction with the first tooth block 22, the second tooth block 25 and the spring 24, motion interference is effectively avoided, and the continuous stirring effect of PHMB pre-stirring, uniform spraying of the diluent and uniform mixing of the two is achieved.
