[0034] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0035] This embodiment provides a technical solution: a circulating water automatic dosing device, such as Figures 1 to 12As shown, it includes a medicine dispensing barrel 3, which is the existing technology. A water pump is arranged inside the medicine dispensing barrel 3. The water outlet end of the water pump is connected to the connecting pipe 2. At the same time, a metering unit is arranged inside the medicine dispensing barrel 3 to monitor the flow of the medicine liquid inside the medicine dispensing barrel 3. A connecting pipe 2 is fixedly connected to the outer wall of the medicine dispensing barrel 3.

[0036] When the liquid medicine in the water circulation pipeline of the pump station unit is used to eliminate impurities, dirt and bacteria in the circulating water, the liquid medicine in the medicine dispensing barrel 3 is introduced into the mixing pipe 12 through the connecting pipe 2, and the circulation pump is turned on to make the circulating water flow in the pipeline, circulate to the docking device 1, and enter the mixing pipe 12 from the water inlet pipe 11. The circulating water entering the mixing pipe 12 will impact the driving device 4, drive the driving device 4 to rotate, and then drive the rotation of the medicine adjusting device 5 through the driving device 4. During the rotation of the medicine adjusting device 5, the liquid medicine in the liquid medicine chamber 124 is evenly transferred to the mixing chamber 121 to mix with the circulating water. The circulating water with evenly mixed liquid medicine flows out through the outlet pipe 13, and the circulating water carrying the liquid medicine cleans and purifies the entire water circulation pipeline.

[0037] The drug adjusting device 5 can mix the drug liquid with the circulating water according to the circulating water speed component. During the circulation process of the circulating water, the circulating water is always dosed with drugs, thereby avoiding the situation where the drug liquid in the circulating water is consumed due to reaction, resulting in a deterioration of the purification effect.

[0038] like Figures 1 to 4As shown, the docking device 1 is a Y-shaped integrated structure, a filter port 14 is provided at the connection position of the mixing tube 12 and the water outlet pipe 13, and a filter screen 15 is fixedly connected to the inner wall of the filter port 14. The filter screen 15 is used to intercept impurities flushed out of the circulating water. After the dosing work is completed, the docking device 1 is taken out and cleaned; a sealing ring 122 is fixedly connected to the end of the mixing tube 12 away from the water inlet pipe 11, and the sealing ring 122 is adapted to the size of the drug adjusting device 5, so that the drug adjusting device 5 rotates on the sealing ring 122 while the mixing chamber 12 is 1 and the liquid medicine chamber 124 are isolated, the sealing ring 122 divides the interior of the mixing tube 12 into a mixing chamber 121 and a liquid medicine chamber 124, the mixing chamber 121 is used to mix the liquid medicine with the circulating water, the liquid medicine chamber 124 is used to store the liquid medicine introduced into the mixing tube 12 by the medicine dispensing barrel 3, and isolate the liquid medicine, a medicine inlet hole 125 connected to the liquid medicine chamber 124 is opened at the center of one end of the mixing tube 12, one end of the connecting tube 2 is fixedly connected to the inner wall of the medicine inlet hole 125 and is connected to the liquid medicine chamber 124, and the inner wall of the mixing chamber 121 is opened with symmetrical rotating holes 123.

[0039] like Figure 2 , Figures 7 to 12 As shown, the medicine adjusting device 5 includes a medicine adjusting sphere 51 rotatably connected to the inner wall of the sealing ring 122, and the outer wall of the medicine adjusting sphere 51 is provided with a plurality of groups of transfer grooves distributed in an annular shape, and the annular distribution direction of the transfer grooves is consistent with the rotation direction of the internal gear 41 of the driving device 4, and each group of transfer grooves is composed of three medicine liquid grooves 511. The medicine adjusting sphere 51 is provided with a second slide groove 513 adapted to the surface of the medicine adjusting sphere 51 near the middle position of the transfer groove, and the second slide groove 513 is used to provide a sliding space for the dewatering unit 53, and the second slide groove 513 is connected with the medicine liquid groove 511. Slide rods 514 are fixedly connected to both ends of the second slide groove 513, and a first slide groove 512 is opened between each two medicine liquid grooves 511 of the medicine adjusting sphere 51. The first slide groove 512 is connected to the second slide groove 513, and the length of the first slide groove 512 is greater than the length of the second slide groove 513, so as to hide the blocking rod 533. A dewatering unit 53 is connected to one end of the second slide groove 513, and dewatering sheets 52 are connected to the inner walls of the medicine liquid groove 511 near both sides of the second slide groove 513, wherein the dewatering unit 53 and the dewatering sheet 52 cooperate with each other to squeeze out the circulating water in the medicine liquid groove 511.

[0040] The dewatering unit 53 includes a dewatering slider 531 slidably connected to the second slide groove 513. The shape of the dewatering slider 531 is adapted to the second slide groove 513. The two ends of the dewatering slider 531 are provided with sliding holes 532 adapted thereto at positions corresponding to the slide rod 514. One side of the dewatering slider 531 is rotatably connected to a stopper 533 adapted thereto at a position corresponding to the first slide groove 512. A stopper shaft (not shown in the figure) is provided at the bottom of the stopper shaft 533. The stopper shaft is rotatably connected to the top of the dewatering slider 531. A torsion spring is provided, and when the baffle rod 533 is not subjected to external force, the baffle rod 533 is always perpendicular to the top of the dewatering slider 531, and the baffle rod 533 can slide along the direction of the first slide groove 512. A matching groove 126 is provided at a position corresponding to the inner wall of the sealing ring 122 and the baffle rod 533. When the medicine tank 511 is full of medicine, the baffle rod 533 can pass through the groove 126 to prevent the dewatering unit 53 and the dewatering sheet 52 from discharging the medicine in the medicine tank 511.

[0041] The dewatering sheet 52 includes a first elastic section 521 and a second elastic section 522, which have the same shape and structure. The middle positions of the first elastic section 521 and the second elastic section 522 are respectively fixedly connected to the two sides of the dewatering slider 531, and the two ends of the first elastic section 521 and the second elastic section 522 are fixedly connected to the inner wall of the medicine liquid tank 511. When the dewatering slider 531 slides on the second slide groove 513, the middle position of the first elastic section 521 and the second elastic section 522 will be driven to move. When the dewatering slider 531 moves from one side of the second slide groove 513 to the other side, the first elastic section 521 and the second elastic section 522 will be flipped to the other side of the medicine liquid tank 511 driven by the dewatering slider 531.

[0042] When the driving device 4 drives the medicine adjusting sphere 51 to rotate, the medicine liquid tank 511 located inside the medicine liquid chamber 124 will be filled with medicine liquid. When the medicine liquid tank 511 rotates on the sealing ring 122, the medicine liquid tank 511 will always keep the medicine liquid in the medicine liquid tank 511 under the sealing of the surface wall of the sealing ring 122 until the medicine liquid tank 511 rotates to one side of the mixing chamber 121. At this time, the medicine liquid inside the medicine liquid tank 511 will be mixed with the circulating water in the mixing chamber 121. At the same time, the medicine adjusting sphere 51 continues to rotate. When the medicine liquid tank 511 located on one side of the mixing chamber 121 rotates to contact the surface wall of the sealing ring 122, the surface wall of the sealing ring 122 blocks the baffle rod 533 of the dewatering unit 53. Since the baffle rod 533 is blocked and limited, and the medicine adjusting sphere 51 is still rotating, the baffle rod 533 will drive the dewatering slider 531 connected thereto to slide on the slide rod 514 on the second slide groove 513, and the sliding dewatering slider 531 will bring When the water removal plate 52 is moved to the inner wall of the other side of the medicine liquid tank 511, the water removal plate 52 and the water removal slider 531 will squeeze and drain the circulating water inside the medicine liquid tank 511, so that when the medicine liquid tank 511 rotates to fit the inner wall of the sealing ring 122, its interior is empty, and then it rotates to the direction of the medicine liquid chamber 124 to take the medicine liquid. When the water removal slider 531 slides to the other side of the second slide groove 513, the second slide groove 513 will limit the water removal slider 531, and at the same time, the sealing ring 122 will have a continuous squeezing force on the baffle rod 533, and the squeezing force will squeeze the baffle rod 533 to rotate on the water removal slider 531, so that it rotates and hides in the first slide groove 512. When it rotates to one side of the medicine liquid chamber 124, the baffle rod 533 will return to its initial position under the action of the torsion spring after the squeezing force of the sealing ring 122 is removed.

[0043] like Figure 2 and Fig.12 As shown, the driving device 4 includes a driving shaft 42 rotatably connected to the inner wall of the rotating hole 123, both ends of the driving shaft 42 are fixedly connected with bearings, the outer ring of the bearing is fixedly connected to the inner wall of the rotating hole 123, the outer wall of the driving shaft 42 is fixedly connected with a gear 41 at a position corresponding to the medicine liquid tank 511, the outer walls of the driving shaft 42 close to both sides of the gear 41 are fixedly connected with a fixed ring 43, the outer wall of the fixed ring 43 is fixedly connected with a plurality of evenly distributed driving blades 44, the gear 41 is meshingly connected with the medicine adjusting sphere 51, when the circulating water enters the mixing chamber 121, it will impact the driving blades 44, and the driving blades 44 drive the driving shaft 42 to rotate in the rotating hole 123 under the impact of the circulating water, and the driving shaft 42 drives the gear 41 to rotate when it rotates, so that the teeth on the gear 41 cooperate with the medicine liquid tank 511 to drive the medicine adjusting sphere 51 to rotate on the sealing ring 122.

[0044] like Figure 2 and Figure 5As shown, the inner walls of both sides of the medicine mixing tube 12 close to the filter screen 15 are fixedly connected with water guide plates 6; the water guide plates 6 are composed of a reduced diameter section 61, a first drainage section 62, a flip section 63, a first drainage section 64 and a second drainage section 65 which are fixedly connected in sequence, one end of the reduced diameter section 61 is fixedly connected to the connection position between the water inlet pipe 11 and the medicine mixing tube 12, the first drainage section 62 is located on one side of the driving device 4, the reduced diameter section 61 is an outward convex structure, the first drainage section 62 is an inward concave structure, the flip section 63 is an outward-turned structure, and the first drainage section 64 and the second drainage section 65 are arc-shaped plate structures.

[0045] When the circulating water enters the mixing medicine tube 12 from the water inlet pipe 11, since the reduced diameter section 61 is convex, the diameter of the connection position between the water inlet pipe 11 and the mixing medicine tube 12 is reduced, thereby increasing the flow rate of the circulating water. When the circulating water passes through the reduced diameter section 61 and enters the first diversion section 62, since the first diversion section 62 is concave, the flow direction of the circulating water can be guided by the first diversion section 62, so that the flow rate of the circulating water on the side of the first diversion section 62 is larger, so that the rotation direction of the driving device 4 can be adjusted to rotate in the set direction. The first diversion section 64 is used to guide the circulating water mixed with the medicine liquid, so that it flows from passing through the filter screen 15 to the water outlet pipe 13. At the same time, the second diversion section 65 can make the circulating water guided by the first diversion section 64 flow back, forming turbulence in front of the filter screen 15, so that the mixing of the medicine liquid and the mixed water is more uniform.

[0046] like Figure 2 and Figure 6 As shown, the bottom of the inner surface wall of the outlet pipe 13 is fixedly connected with a first retarder 7, and the top of the inner surface wall of the outlet pipe 13 is fixedly connected with a second retarder 8 at a position corresponding to the first retarder 7. The first retarder 7 is a ring structure rotated 200°, and the second retarder 8 is a ring structure rotated 160°. The first retarder 7 is formed by the second diversion section 71 and the third diversion section 72 being fixedly connected, and the second diversion section 71 and the third diversion section 72 are connected to form an hourglass-shaped structure, and the second retarder 8 is formed by the third diversion section 81, the turbulent section 82 and the fourth diversion section 83. The two ends of the turbulent section 82 are fixedly connected to the third drainage section 81 and the fourth guide section 83 respectively. The third drainage section 81 and the fourth guide section 83 are both concave arc structures, and the turbulent section 82 is a wave-shaped structure. The circulating water liquid medicine entering the outlet pipe 13 from the filter screen 15 flows to the turbulent section 82 under the guidance of the second drainage section 71. The circulating water liquid medicine is decelerated by the turbulent section 82, so that the speed of the circulating water liquid medicine is reduced between the first retarder 7 and the second retarder 8, thereby further mixing with the liquid medicine entering the outlet pipe 13 later, thereby helping to increase the mixing effect.

[0047] The working principle of the technical solution provided by the present invention is as follows: when the liquid medicine in the water circulation pipeline of the pump station unit is used to eliminate impurities, dirt and bacteria in the circulating water, the liquid medicine inside the medicine dispensing barrel 3 is introduced into the mixing pipe 12 through the connecting pipe 2, and the circulation pump is turned on to allow the circulating water to flow in the pipeline, circulate to the docking device 1, and enter the mixing pipe 12 from the water inlet pipe 11.

[0048] When the circulating water enters the mixing tube 12 from the water inlet pipe 11, the diameter reduction section 61 is convex, thereby reducing the diameter of the connection position between the water inlet pipe 11 and the mixing tube 12, thereby increasing the flow rate of the circulating water. When the circulating water passes through the diameter reduction section 61 and enters the first drainage section 62, since the first drainage section 62 is concave, the flow direction of the circulating water can be guided by the first drainage section 62, so that the circulating water flow rate on one side of the first drainage section 62 is larger, so that the rotation direction of the driving device 4 can be adjusted to rotate in the set direction. When the circulating water enters the mixing chamber 121, it will impact the driving blades 44. The driving blades 44 drive the driving shaft 42 to rotate inside the rotating hole 123 under the impact of the circulating water. When the driving shaft 42 rotates, it drives the gear 41 to rotate, thereby driving the medicine adjusting ball 51 to rotate on the sealing ring 122 through the cooperation between the teeth on the gear 41 and the medicine liquid tank 511.

[0049] When the driving device 4 drives the medicine adjusting sphere 51 to rotate, the medicine liquid tank 511 located inside the medicine liquid chamber 124 will be filled with medicine liquid. When the medicine liquid tank 511 rotates on the sealing ring 122, the medicine liquid tank 511 will always keep the medicine liquid in the medicine liquid tank 511 under the sealing of the surface wall of the sealing ring 122 until the medicine liquid tank 511 rotates to one side of the mixing chamber 121. At this time, the medicine liquid inside the medicine liquid tank 511 will be mixed with the circulating water in the mixing chamber 121. At the same time, the medicine adjusting sphere 51 continues to rotate. When the medicine liquid tank 511 located on one side of the mixing chamber 121 rotates to contact the surface wall of the sealing ring 122, the surface wall of the sealing ring 122 blocks the baffle rod 533 of the dewatering unit 53. Since the baffle rod 533 is blocked and limited, and the medicine adjusting sphere 51 is still rotating, the baffle rod 533 will drive the dewatering slider 531 connected thereto to slide on the slide rod 514 on the second slide groove 513, and the sliding dewatering slider 531 will bring When the water removal plate 52 is moved to the inner wall of the other side of the medicine liquid tank 511, the water removal plate 52 and the water removal slider 531 will squeeze and drain the circulating water inside the medicine liquid tank 511, so that when the medicine liquid tank 511 rotates to fit the inner wall of the sealing ring 122, its interior is empty, and then it rotates to the direction of the medicine liquid chamber 124 to take the medicine liquid. When the water removal slider 531 slides to the other side of the second slide groove 513, the second slide groove 513 will limit the water removal slider 531, and at the same time, the sealing ring 122 will have a continuous squeezing force on the baffle rod 533, and the squeezing force will squeeze the baffle rod 533 to rotate on the water removal slider 531, so that it rotates and hides in the first slide groove 512. When it rotates to one side of the medicine liquid chamber 124, the baffle rod 533 will return to its initial position under the action of the torsion spring after the squeezing force of the sealing ring 122 is removed.

[0050] The circulating water liquid medicine that enters the outlet pipe 13 from the filter screen 15 flows to the turbulent section 82 under the guidance of the second drainage section 71, and is decelerated by the turbulent section 82, so that the circulating water liquid medicine speed is reduced between the first retarder 7 and the second retarder 8, thereby further mixing with the medicine liquid that subsequently enters the outlet pipe 13, thereby helping to increase the mixing effect. The evenly mixed circulating water with medicine liquid then flows out through the outlet pipe 13, and the circulating water carrying the medicine liquid cleans and purifies the entire water circulation pipeline.

[0051] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.
