Abstract
Description
Technical Field
[0001] This invention specifically relates to the field of automatic dosing technology, and more specifically to an automatic dosing device and method for industrial water treatment. Background Technology
[0002] Automatic dosing devices for industrial water treatment are core supporting equipment in industrial circulating water, sewage, and wastewater pretreatment and deep treatment systems. They are used to achieve automatic dissolution, accurate metering and stable dosing of flocculants such as PAC, PAM and PFS. They remove suspended solids, colloids and pollutants in water through charge neutralization and adsorption bridging, ensuring that the effluent turbidity, total phosphorus and other indicators meet the standards. Traditional dosing systems require a separate transport device to add chemicals, which prevents the chemicals from being transported synchronously with the water, resulting in incomplete water treatment. Some existing dosing systems also require manual addition of chemicals, where workers mix a certain amount of chemicals with a certain amount of industrial water, then stir and let it stand, further reducing water treatment efficiency. A search revealed that Chinese patent application CN202022422580.7 discloses an automatic dosing device for industrial water treatment; it includes a mixing tank, with support rods A installed at both ends of the bottom of the mixing tank, the bottom ends of the support rods A mounted on gaskets, a motor housing installed at the center of the bottom of the mixing tank, a chemical storage tank located directly above the mixing tank, a sewage inlet pipe located at the top of one side of the outer wall of the mixing tank, a sewage valve installed on the sewage inlet pipe, and a control box and a water outlet pipe located on the other side of the outer wall of the mixing tank, the control box located above the water outlet pipe, and a water outlet valve installed on the water outlet pipe; When adding the medicine, the device in the aforementioned patent requires water and medicine to be added separately. This necessitates prolonged stirring with a stirring device to ensure uniform mixing. Furthermore, the device cannot separate impurities generated after mixing the medicine and water. Additionally, the device can only add a certain amount of water and medicine before adding more water and medicine, which fails to achieve continuous treatment and reduces the efficiency of water treatment. Summary of the Invention
[0003] The purpose of this invention is to provide an automatic dosing device and method for industrial water treatment. In this device, water from a storage tank is drawn into a rotating impeller housing by a first pump. The water impacts the blades, causing the rotating impeller housing to rotate.

A ratchet at the bottom of the first shaft drives a rotating protrusion to cooperate with a squeezing cylinder, enabling simultaneous addition of chemicals during water intake. When water enters the tank, it spirals and actively descends along the inner wall of the conical hopper, achieving a flushing and mixing effect on the chemicals, reducing dosage by half. As flocculants are generated in the water, the rotating blades mounted on the second shaft transfer the flocculants to a filter screen, achieving separation of water and flocculants.

[0005] As a further technical solution of the present invention, a first rotating shaft is fixedly installed at the bottom of the rotating impeller housing; a first gear is fixedly installed on the first rotating shaft; and a rotating protrusion is installed at the bottom of the end of the first rotating shaft away from the rotating impeller housing via a ratchet.
[0006] As a further technical solution of the present invention, one side of the first gear is meshed with the second gear; the first gear and the second gear are located at the top of the tank; the second gear is fixedly installed at the top of the second rotating shaft; the second rotating shaft is movably installed with the top cover of the tank via a bearing; a auger blade is provided on the surface of the end of the second rotating shaft away from the second gear; the auger blade is located inside the filter screen.
[0007] As a further technical solution of the present invention, the dosing tank is further provided with a dosing assembly; the dosing assembly includes a connecting pipe; the connecting pipe is fixedly installed at the bottom of the tank; one end of the connecting pipe is fixedly installed with the dosing tank; the end of the connecting pipe away from the dosing tank extends into the tank, and a baffle is fixedly installed on the outer wall of the connecting pipe.
[0008] As a further technical solution of the present invention, a squeezing cylinder is movably installed on the top of one end of the connecting pipe extending into the tank body; a first cavity is provided between the bottom of the inner side of the squeezing cylinder and the top of the connecting pipe; two second cavities are also provided inside the squeezing cylinder; a second ball is provided inside one of the bottom second cavities; a spring is provided between the squeezing cylinder and the baffle on the connecting pipe; the squeezing cylinder is fitted and connected to the arc-shaped surface at the bottom of the rotating protrusion.
[0009] As a further technical solution of the present invention, the second cavity at the top of the inner side of the extrusion cylinder is configured to penetrate the drug outlet pipe; the end of the drug outlet pipe away from the extrusion cylinder extends to the inclined surface of the inner wall of the conical hopper; a first cavity is provided between the top of the extrusion cylinder and the connecting pipe; a second sphere is provided in the first cavity; the second sphere cooperates with the top of the connecting pipe.
[0010] As a further technical solution of the present invention, a backwash drain port is also fixedly installed on the side wall of the tank; the backwash drain port is located above the top of the conical bucket; and the side wall at the bottom of the tank is also connected to the second pump body through a pipe.
[0011] As a further technical solution of the present invention, an automatic dosing device and method for industrial water treatment includes the following steps: S1, Water Storage: Industrial water is transferred to the water storage tank through the inlet installed on the water storage tank. Multiple filter layers are set inside the water storage tank to filter out larger impurities in the water and avoid blockage when the first pump body draws water. S2, Chemical Dosing and Flocculation: The first pump body transmits water to the inside of the rotating impeller housing through the inlet pipe. The water impacts multiple blades, causing the bottom plate of the rotating impeller housing to rotate. Water is transmitted from the outlet pipe on the other side of the rotating impeller housing to the inside of the conical bucket. The water rotates and descends along the inner surface of the conical bucket. At the same time, the bottom plate of the rotating impeller housing drives the first gear and the rotating protrusion at the bottom to rotate through the first rotating shaft. At this time, the arc surface at the bottom of the rotating protrusion contacts the top of the extrusion cylinder, thereby pressurizing the extrusion cylinder downward. When the extrusion cylinder moves downward, the second ball between the extrusion cylinder and the connecting pipe draws the liquid medicine in the medicine tank to the top of the conical bucket, thereby achieving the mixing and flocculation between the liquid medicine and the water. S3, Filtration and Separation: The flocculent produced after the drug solution and water are mixed is pressurized downward by the auger blades installed on the second rotating shaft. The flocculent and water are separated by the filter screen. The separated water is pumped by the second pump body and transferred to the next process. S4. During filtration and separation, the second gear installed on the second rotating shaft meshes with the first gear installed on the first rotating shaft to achieve synchronous rotation, thus avoiding clogging of the connection between the conical hopper and the filter screen by flocculent material. S5. Backwashing: First, close the pipe between the second pump body and the tank. By rotating the lead screw, the lead screw drives the fixed frame and double round head plate through the threaded cylinder to push and pull the connecting rod. The connecting rod and the blade are set eccentrically, which can adjust the tilt angle of the blade. Then, the blade is impacted by water, causing the rotating impeller shell to flip. The water still enters the conical bucket through the outlet pipe. At this time, the ratchet at the bottom of the first rotating shaft rotates freely, so that the rotating cam cannot squeeze the extrusion cylinder. At this time, no more medicine is added. At the same time, the auger blades reverse, transferring the flocculent in the filter screen to the top. As the water level inside the tank rises, the water with flocculent is discharged through the backwash drain port installed on the side wall of the tank.
[0012] Compared with the prior art, the beneficial effects of the present invention are: In this invention, industrial water is introduced into the storage tank through the inlet installed in the storage tank. The filtered water inside the storage tank is then introduced into the rotating impeller housing through the first pump body. The water pressure impacts the blades on the side wall of the support frame, and the water is added to the conical hopper from the outlet pipe on the other side of the rotating impeller housing. The support frame drives the rotating plate at the bottom of the rotating impeller housing to rotate the first shaft. The ratchet installed at the bottom of the first shaft drives the rotating protrusion to cooperate with the dosing assembly, thereby achieving automatic dosing during the water intake process. In this invention, during drug addition, when the protrusion at the bottom of the rotating cam contacts the top of the extrusion cylinder, it presses the extrusion cylinder downward. At this time, the second ball inside the first cavity between the extrusion cylinder and the connecting pipe remains stationary, while the second ball inside the second cavity at the bottom of the extrusion cylinder moves upward, thus transferring the liquid medicine in the first cavity to the dispensing pipe for drug addition. When the protrusion at the bottom of the rotating cam separates from the top of the extrusion cylinder, the extrusion cylinder is reset upward under the action of the spring and the baffle. At this time, the position of the second ball in the second cavity is different, and the second ball in the first cavity moves upward, transferring the liquid medicine in the medicine tank to the first cavity through negative pressure, thus achieving the effect of continuous automatic drug addition. In this invention, when the first shaft drives the first gear to rotate forward, and the first gear meshes with the second gear on the second shaft, the second gear realizes the rotation of the auger blades through the second shaft. When water is added to the inner wall of the conical bucket, the water will spiral down along the inner wall of the conical bucket. At the same time, the spiral of the water disperses the added medicine, accelerating the mixing between the water and the medicine. The speed at which the water and medicine are mixed by the auger blades slows down. At this time, the generated flocculent is filtered by the filter screen, and the water is filtered into the tank at the bottom of the conical bucket. The water that has been flocculated by the medicine is extracted by the second pump. This invention, through a controller timing, after a period of operation, first closes the pipeline between the second pump body and the tank. The operator rotates the lead screw, which moves downward through the threaded cylinder, causing the fixed frame and double round head plate to drive the connecting rod downward to push the back of the blades downward, causing the blades to rotate 180° in the tilt direction. At this time, when the water pressure impacts the blades again, the bottom plate at the bottom of the rotating impeller housing reverses. At this time, the first gear and the second gear mesh in opposite directions, and the rotating cam stops rotating under the action of the ratchet. At this time, the auger blades on the second rotating shaft reverse, causing the flocculent in the filter screen to rotate upward. As the water inside the tank increases, the flocculent and water are discharged through the backwash drain port installed on the tank. Attached Figure Description

One side of the rotating impeller housing 61 is connected to the outlet of the first pump body 4 via an inlet pipe 63; the inlet of the first pump body 4 is fixedly installed to the bottom of the water storage tank 2; an outlet pipe 62 is provided on the other side of the rotating impeller housing 61; the outlet pipe 62 extends into the tank body 60. A first rotating shaft 64 is fixedly installed at the bottom of the rotating impeller housing 61; a first gear 65 is fixedly installed on the first rotating shaft 64; a rotating protrusion 611 is installed at the bottom of the first rotating shaft 64 away from the rotating impeller housing 61 via a ratchet 610; By adopting the above technical solution, during use, industrial water is transferred into the water storage tank 2 through the inlet installed in the water storage tank 2. The water filtered inside the water storage tank 2 is transferred into the rotating impeller housing 61 through the first pump body 4. The water pressure impacts the blades 612 on the side wall of the support frame 618. Water is added to the conical bucket 10 from the outlet pipe 62 on the other side of the rotating impeller housing 61. The support frame 618 drives the rotating plate at the bottom of the rotating impeller housing 61 to rotate the first rotating shaft 64. The ratchet 610 installed at the bottom of the first rotating shaft 64 drives the rotating protrusion 611 to cooperate with the dosing assembly 9, so as to achieve the effect of automatic dosing during the water intake process.
[0031] Please see Figure 3-8 In this embodiment, one side of the first gear 65 is meshed with the second gear 66; the first gear 65 and the second gear 66 are located at the top of the tank body 60; the second gear 66 is fixedly installed on the top of the second rotating shaft 68; the second rotating shaft 68 is movably installed with the top cover of the tank body 60 via a bearing; a auger blade 69 is provided on the surface of the end of the second rotating shaft 68 away from the second gear 66; the auger blade 69 is located inside the filter screen 11. In this embodiment, the dosing tank 6 is further provided with a dosing assembly 9; the dosing assembly 9 includes a connecting pipe 90; the connecting pipe 90 is fixedly installed at the bottom of the tank body 60; one end of the connecting pipe 90 is fixedly installed with the dosing tank 6; the end of the connecting pipe 90 away from the dosing tank 6 extends into the tank body 60, and a baffle 93 is fixedly installed on the outer wall of the connecting pipe 90. By adopting the above technical solution, when the rotating protrusion 611 contacts the top of the extrusion cylinder 91 during drug addition, it presses the extrusion cylinder 91 downward. At this time, the second ball 94 in the first cavity 96 between the extrusion cylinder 91 and the connecting pipe 90 remains stationary, while the second ball 95 in the second cavity 97 at the bottom of the inner side of the extrusion cylinder 91 moves upward, thus transferring the liquid medicine in the first cavity 96 to the dispensing pipe 98 for drug addition. When the protrusion at the bottom of the rotating protrusion 611 separates from the top of the extrusion cylinder 91, the extrusion cylinder 91 is reset upward under the action of the spring 92 and the baffle 93. At this time, the second ball 95 in the second cavity 97 is in a different position, and the second ball 94 in the first cavity 96 moves upward, transferring the liquid medicine in the medicine tank 8 to the first cavity 96 through negative pressure, thus achieving the effect of continuous automatic drug addition.
[0032] Please see Figure 7-13 Furthermore, a compression cylinder 91 is movably installed at the top of one end of the connecting pipe 90 extending into the tank 60; a first cavity 96 is provided between the bottom of the inner side of the compression cylinder 91 and the top of the connecting pipe 90; two second cavities 97 are also provided inside the compression cylinder 91; a second ball 95 is provided inside one of the bottom second cavities 97; a spring 92 is provided between the compression cylinder 91 and the baffle 93 on the connecting pipe 90; the compression cylinder 91 is fitted and connected to the arc-shaped surface at the bottom of the rotating protrusion 611. In this embodiment, the second cavity 97 at the top of the inner side of the extrusion cylinder 91 is connected to the medicine outlet pipe 98; the end of the medicine outlet pipe 98 away from the extrusion cylinder 91 extends to the inclined surface of the inner wall of the conical bucket 10; a first cavity 96 is provided between the top of the extrusion cylinder 91 and the connecting pipe 90; a second ball 94 is provided in the first cavity 96; the second ball 94 cooperates with the top of the connecting pipe 90. By adopting the above technical solution, when the first rotating shaft 64 drives the first gear 65 to rotate forward, and the first gear 65 meshes with the second gear 66 on the second rotating shaft 68, the second gear 66 realizes the rotation of the auger blades 69 through the second rotating shaft 68. When water is added to the inner wall of the conical bucket 10, the water will spiral down along the inner wall of the conical bucket 10. At the same time, the spiral of the water disperses the added medicine and accelerates the mixing between the water and the medicine. The speed at which the water and medicine are mixed by the auger blades 69 slows down. At this time, the generated flocculent is filtered by the filter screen 11, and the water is filtered into the tank 60 at the bottom of the conical bucket 10. The water that has been added and flocculated is extracted by the second pump body 7. Furthermore, a backwash drain port 67 is also fixedly installed on the side wall of the tank body 60; the backwash drain port 67 is located above the top of the conical bucket 10; the side wall at the bottom of the tank body 60 is also connected to the second pump body 7 through a pipe. By adopting the above technical solution, and using the controller 3 for timing, after working for a period of time, the pipeline between the second pump body 7 and the tank 60 is first closed. The operator rotates the screw 617, which moves downward through the threaded cylinder 616, so that the fixed frame 615 and the double round head plate 614 drive the connecting rod 613 to push the back of the blade 612 downward, so that the tilt direction of the blade 612 rotates 180°. At this time, when the water pressure impacts the blade 612 again, the bottom plate at the bottom of the rotating impeller housing 61 reverses. At this time, the first gear 65 and the second gear 66 mesh in opposite directions, and the rotating cam 611 stops rotating under the action of the ratchet 610. At this time, the auger blade 69 on the second rotating shaft 68 reverses, so as to rotate the flocculent in the filter screen 11 upward. As the water inside the tank 60 increases, the flocculent and water are discharged through the backwash drain port 67 installed on the tank 60.
[0033] Please see Figure 1-15 An automatic dosing device and method for industrial water treatment includes the following steps: S1, Water storage: Industrial water is transferred to the inside of the water storage tank 2 through the water inlet installed on the water storage tank 2. Multiple filter layers are set inside the water storage tank 2 to filter out larger impurities in the water and avoid blockage when the first pump body 4 draws water. S2, Chemical Dosing and Flocculation: The first pump body 4 transmits water to the interior of the rotating impeller housing 61 through the water inlet pipe 63. The water impacts multiple blades 612, causing the rotating impeller housing 61 to rotate. When the rotating impeller housing 61 rotates, water is transmitted from the water outlet pipe 62 on the other side of the rotating impeller housing 61 to the interior of the conical bucket 10. The water rotates and descends along the inner surface of the conical bucket 10. At the same time, the rotating impeller housing 61 drives the first gear 65 and the rotating protrusion 611 at the bottom to rotate through the first rotating shaft 64. At this time, the arc surface at the bottom of the rotating protrusion 611 contacts the top of the extrusion cylinder 91, thereby pressurizing the extrusion cylinder 91 downward. When the extrusion cylinder 91 moves downward, the second ball 94 and the second ball 95 set between the extrusion cylinder 91 and the connecting pipe 90 draw the liquid medicine in the medicine tank 8 to the top of the conical bucket 10, thereby achieving the mixing and flocculation between the liquid medicine and the water. S3, Filtration and Separation: The flocculent produced after the medicine solution and water are mixed is pressurized downward by the auger blades 69 installed on the second rotating shaft 68. The flocculent and water are separated by the filter screen 11. The separated water is pumped by the second pump body 7 and transferred to the next process. S4. During filtration and separation, the second gear 66 installed on the second rotating shaft 68 meshes with the first gear 65 installed on the first rotating shaft 64 to achieve synchronous rotation, thus avoiding clogging of the connection between the conical bucket 10 and the filter screen 11 by flocculent material. S5. Backwashing: First, close the pipe between the second pump body 7 and the tank 60; by rotating the lead screw 617, the lead screw 617 drives the fixed frame 615 and the double round head plate 614 through the threaded cylinder 616 to push and pull the connecting rod 613. The connecting rod 613 and the blade 612 are eccentrically set, so that the tilt angle of the blade 612 can be adjusted. Then, by water impacting the blade 612, the rotating impeller housing 61 is flipped. The water still enters the conical bucket 10 through the outlet pipe 62. At this time, the ratchet 610 at the bottom of the first rotating shaft 64 rotates freely, so that the rotating protrusion 611 cannot squeeze the extrusion cylinder 91. At this time, no more medicine is added. At the same time, the auger blade 69 reverses, transferring the flocculent in the filter screen 11 to the top. As the water level inside the tank 60 rises, the water with flocculent is discharged through the backwash drain port 67 installed on the side wall of the tank 60.
[0034] The working principle of this invention is as follows: During use, industrial water is transferred into the water storage tank 2 through the inlet installed in the water storage tank 2. The water filtered inside the water storage tank 2 is transferred into the rotating impeller housing 61 through the first pump body 4. The water pressure impacts the blades 612 on the side wall of the support frame 618. Water is added to the conical bucket 10 from the outlet pipe 62 on the other side of the rotating impeller housing 61. The support frame 618 drives the rotating plate at the bottom of the rotating impeller housing 61 to rotate the first rotating shaft 64. The ratchet 610 installed at the bottom of the first rotating shaft 64 drives the rotating protrusion 611 to cooperate with the dosing assembly 9 to achieve the effect of automatic dosing during the water intake process. When adding medicine, when the protrusion at the bottom of the rotating protrusion 611 contacts the top of the extrusion cylinder 91, it presses the extrusion cylinder 91 downward. At this time, the second ball 94 in the first cavity 96 between the extrusion cylinder 91 and the connecting pipe 90 remains stationary, while the second ball 95 in the second cavity 97 at the bottom of the inner side of the extrusion cylinder 91 moves upward, thus transferring the medicine in the first cavity 96 to the medicine outlet pipe 98 for addition. When the protrusion at the bottom of the rotating protrusion 611 separates from the top of the extrusion cylinder 91, the extrusion cylinder 91 is reset upward under the action of the spring 92 and the baffle 93. At this time, the second ball 95 in the second cavity 97 is in a different position, and the second ball 94 in the first cavity 96 moves upward, transferring the medicine in the medicine tank 8 to the first cavity 96 through negative pressure, thus achieving the effect of continuous automatic addition. When the first shaft 64 drives the first gear 65 to rotate forward, and the first gear 65 meshes with the second gear 66 on the second shaft 68, the second gear 66 rotates the auger blades 69 through the second shaft 68. When water is added to the inner wall of the conical hopper 10, the water will spiral down along the inner wall of the conical hopper 10. At the same time, the spiral of the water disperses the added medicine and accelerates the mixing between the water and the medicine. The speed at which the water and medicine are mixed by the auger blades 69 slows down. At this time, the generated flocculent is filtered by the filter screen 11, and the water is filtered into the tank 60 at the bottom of the conical hopper 10. The water that has been added and flocculated is extracted by the second pump body 7. Using the controller 3 to time the process, after a period of operation, the pipe between the second pump body 7 and the tank 60 is first closed. The operator rotates the screw 617, which moves downward through the threaded cylinder 616. This causes the fixed frame 615 and the double round head plate 614 to drive the connecting rod 613 to push the back of the blade 612 downward, causing the blade 612 to rotate 180° in the tilt direction. At this time, when the water pressure impacts the blade 612 again, the bottom plate at the bottom of the rotating impeller housing 61 reverses. At this time, the first gear 65 and the second gear 66 mesh in opposite directions, and the rotating cam 611 stops rotating under the action of the ratchet 610. At this time, the auger blade 69 on the second rotating shaft 68 reverses, causing the flocculent material in the filter screen 11 to rotate upward. As the water inside the tank 60 increases, the flocculent material and water are discharged through the backwash drain port 67 installed on the tank 60.

8. The method of the automatic dosing device for industrial water treatment according to any one of claims 1-7, characterized in that: Includes the following steps: S1, Water storage: Industrial water is transmitted to the inside of the water storage tank (2) through the inlet installed on the water storage tank (2). Multiple layers of filter are installed inside the water storage tank (2) to filter out larger impurities in the water and avoid blockage when the first pump (4) draws water. S2, Chemical Dosing and Flocculation: The first pump body (4) transmits water to the interior of the rotating impeller housing (61) through the inlet pipe (63), and the water impacts multiple blades (612), causing the rotating impeller housing (61) to rotate. While the rotating impeller housing (61) is rotating, water is transmitted from the outlet pipe (62) on the other side of the rotating impeller housing (61) to the interior of the conical bucket (10). The water rotates and descends along the inner surface of the conical bucket (10). At the same time, the rotating impeller housing (61) passes through the first rotating shaft (64). The first gear (65) and the bottom rotating protrusion (611) are driven to rotate. At this time, the arc surface at the bottom of the rotating protrusion (611) contacts the top of the extrusion cylinder (91), thereby pressurizing the extrusion cylinder (91) downward. When the extrusion cylinder (91) moves downward, the medicine liquid in the medicine tank (8) is drawn to the top of the conical bucket (10) through the second ball (94) and the second ball (95) set between the inside of the extrusion cylinder (91) and the connecting pipe (90), thereby achieving the mixing and flocculation between the medicine liquid and water. S3, Filtration and Separation: The flocculent produced after the medicine solution and water are mixed is pressurized downward by the dragon blade (69) installed on the second rotating shaft (68). The flocculent and water are separated by the filter screen (11). The separated water is pumped by the second pump body (7) and transferred to the next process. S4. During filtration and separation, the second gear (66) installed on the second rotating shaft (68) meshes with the first gear (65) installed on the first rotating shaft (64) to achieve synchronous rotation, thus avoiding clogging of the connection between the conical bucket (10) and the filter screen (11) by the flocculents. S5, Backwashing: First, close the pipe between the second pump body (7) and the tank (60); by rotating the screw (617), the screw (617) drives the fixed frame (615) and the double round head plate (614) through the threaded cylinder (616) to push and pull the connecting rod (613). The connecting rod (613) and the blade (612) are eccentrically set, so that the tilt angle of the blade (612) can be adjusted. Then, by water impacting the blade (612), the rotating impeller shell (61) flips. As the water continues to flow through the outlet pipe (62), it enters the conical bucket (10). At this time, the ratchet (610) at the bottom of the first rotating shaft (64) rotates freely, preventing the rotating protrusion (611) from squeezing the extrusion cylinder (91). No more medicine is added at this time. Meanwhile, the dragon blade (69) reverses direction, transferring the flocculent material in the filter screen (11) to the top. As the water level inside the tank (60) rises, the water with flocculent material is discharged through the backwash drain port (67) installed on the side wall of the tank (60).
