Description

Technical Field

[0001] The present invention relates to the technical field of dosing devices, and in particular to an intelligent dosing device for water treatment and a dosing method thereof. Background Art

[0002] Water treatment refers to the process of removing substances that are harmful to production and life in water through physical, chemical or biological methods, or reducing the content of such substances so that the water quality meets the requirements of specific purposes. During the water treatment process, a certain amount of medicine is generally added to the water through a dosing device to remove harmful substances in the water. The added medicine is generally divided into two types: liquid medicine or powder medicine.

[0003] Existing dosing devices generally sprinkle drug powder directly into water. The drug powder may clump when it comes into contact with water. Combined with the fact that the drug powder itself becomes damp and clumps, after the drug powder is added to water, there may be large particles of clumped drug powder, which reduces the rate at which the drug powder dissolves in water, and part of the water is in a static state, thereby reducing the diffusion rate of the drug in the water and reducing the dosing rate of the device.

DETAILED DESCRIPTION

[0038] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] Embodiment 1: The present invention provides a technical solution: Referring to Figure 1 - Fig.13 The present invention discloses an intelligent dosing device for water treatment, comprising a water storage cylinder 1, a dosing component 2 is arranged on the water storage cylinder 1, and a mixing component 3 is arranged in the water storage cylinder 1;

[0040] The medicine mixing component 3 includes a fixed tube 31, which is arranged at the axial position in the water storage cylinder 1, and the top of the fixed tube 31 is fixedly connected to the inner top wall of the water storage cylinder 1, and a grinding disc 32 is arranged on the bottom side of the fixed tube 31, and the top of the grinding disc 32 is inserted into the fixed tube 31 and is rotatably connected to the inner wall of the bottom opening of the fixed tube 31 through a bearing, and two sealing rings 33 are fixedly installed in the tube wall of the fixed tube 31 at the position corresponding to the grinding disc 32, and the inner ring wall of each sealing ring 33 is in contact with the outer peripheral wall of the grinding disc 32, and the grinding disc 32 is fixedly connected to the inner wall of the bottom opening of the fixed tube 31 through a bearing. 2 is provided with a grinding plate 34 at the bottom side, and a plurality of support rods 38 are fixedly installed on the bottom side of the grinding plate 34 in a circumferential array, and the bottom end of each support rod 38 is fixedly connected to the inner wall of the water storage cylinder 1, two groups of pressure limiting valves 35 are provided on the outer circumference of the top of the fixed pipe 31 from top to bottom, and a plurality of pressure limiting valves 35 in each group are arranged in a circumferential array, and the pressure limiting valves 35 are fixedly penetrated through the wall of the fixed pipe 31, an impeller 36 is provided above the grinding disc 32, a medicine spreading mechanism 4 is provided at the bottom of the fixed pipe 31, and a driving mechanism 5 is provided on the outer circumference of the bottom of the grinding disc 32.

[0041] In this embodiment, when the improved water treatment intelligent dosing device is used, the driving mechanism 5 drives the grinding disc 32 to rotate continuously, and drives the impeller 36 to rotate synchronously. The rotating impeller 36 pushes the gas in the fixed tube 31 downward, so that a negative pressure cavity is continuously formed at the top of the fixed tube 31. At this time, a pressure difference is continuously formed at both ends of the pressure limiting valve 35. The gas in the water storage cylinder 1 passes through the pressure limiting valve 35 on the top side and flows into the fixed tube 31 to replenish the gas lost in the fixed tube 31, and the water at the top of the water storage cylinder 1 is discharged by the next group of pressure limiting valves. The water flows into the fixed pipe 31 from the pressure limiting valve 35 to replenish the other part of the gas lost in the fixed pipe 31, and the water flows into the fixed pipe 31 from the pressure limiting valve 35 and flows downward along the pressure limiting valve 35 along the pipe wall of the fixed pipe 31, and finally passes through the inner hole of the grinding disc 32 and the gap between the grinding disc 32 and the grinding plate 34 to be discharged from the fixed pipe 31, and finally the inner hole of the grinding disc 32 and the gap between the grinding disc 32 and the grinding plate 34 are continuously discharged from the gas and water, and finally a circulation flow of water and gas is formed in the water storage cylinder 1 and the fixed pipe 31;

[0042] During the rotation of the grinding disc 32, the dosing assembly 2 can be driven synchronously to operate, so that the powder is continuously and relatively evenly sprinkled on the top side of the grinding disc 32, and then carried away by the flowing water and air flow, and flows into the water in the water storage cylinder 1 through the gap between the grinding disc 32 and the grinding plate 34. As the amount of water circulation changes, the amount of powder is also automatically adjusted synchronously. The device is highly intelligent and does not require the operator to perform other operations.

[0043] When the above-mentioned medicine powder is located in the gap between the grinding disc 32 and the grinding plate 34, the rotating grinding disc 32 can grind the lumps and medicine powder in the medicine powder into finer powders, and make the water and the medicine powder fully contact, and at the same time, the medicine powder will not form lumps when it contacts with water, and finally the medicine powder is fully dissolved in the water, and the medicine liquid with high concentration is continuously discharged from the outer peripheral side of the gap between the grinding disc 32 and the grinding plate 34, and the medicine liquid and the airflow are divided into multiple small airflows and small medicine liquids by the medicine spreading mechanism 4 and spread in the water at the bottom of the water storage cylinder 1, and the circulation of water in the water storage cylinder 1 and the fixed pipe 31 is coordinated, so that the medicine in the water of the water storage cylinder 1 can be quickly diffused and mixed with the water, and at the same time, many small airflows continue to pass through the water in the water storage cylinder 1, which can stir the water in the water storage cylinder 1 to a certain extent, further accelerate the diffusion rate of the medicine in the water, and improve the dosing rate of the device;

[0044] It should be noted that a control panel is fixedly mounted on the outer wall of the water storage cylinder 1 to control the operating status of the device, and a water level sensor is fixedly mounted on the inner wall of the water storage cylinder 1 to monitor the water storage amount in the water storage cylinder 1 .

[0045] In a further preferred embodiment of the present invention, Figure 2 As shown, an electrically controlled water inlet valve 6 is fixedly installed through the top side of the water storage cylinder 1, the inner bottom wall of the water storage cylinder 1 is an arc-shaped arrangement with the periphery concave toward the center, and an electrically controlled drain valve 7 is fixedly installed through the center position of the bottom side of the water storage cylinder 1, and the top end of the electrically controlled drain valve 7 is coplanar with the inner bottom side of the water storage cylinder 1;

[0046] In this embodiment, when the device is used, the operator starts the device through the control panel control device. First, the electric water inlet valve 6 is opened, and the water in the water input pipe flows into the water storage cylinder 1 through the electric water inlet valve 6. After the water level sensor detects that the water in the water storage cylinder 1 reaches the threshold, the electric water inlet valve 6 is closed. At this time, a certain amount of water is stored in the water storage cylinder 1, and the water level exceeds a group of pressure limiting valves 35 on the bottom side, and the injection of water into the water storage cylinder 1 is completed;

[0047] After the above-mentioned water dosing operation is completed, the electric-controlled drain valve 7 is started, and the water in the water storage cylinder 1 gradually gathers toward the electric-controlled drain valve 7 along the inner bottom of the water storage cylinder 1, and is discharged from the water storage cylinder 1 through the electric-controlled drain valve 7. After the water in the water storage cylinder 1 is discharged, the electric-controlled drain valve 7 is closed, and then the electric-controlled water inlet valve 6 is opened. According to the above-mentioned repeated operations, the water dosing treatment can be continuously performed, the device has a high degree of intelligence, and the operator's work intensity is reduced;

[0048] It should be noted that the water inlet end of the above-mentioned electric-controlled water inlet valve 6 is connected and installed with the water discharge end of the water input pipe, and the discharge end of the above-mentioned electric-controlled drain valve 7 is connected and installed with the water inlet end of the water discharge pipe.

[0049] In a further preferred embodiment of the present invention, Figure 3 , Figure 7and Figure 8 As shown, the top side of the grinding disc 32 is set in an arc shape with the periphery concave toward the center position, the central part of the grinding plate 34 is set in a truncated cone shape and inserted into the inner hole of the grinding disc 32 to match the inner hole wall gap of the grinding disc 32, and the top side of the grinding plate 34 is set in an arc shape;

[0050] In this embodiment, the arcuate surface of the top side of the grinding disc 32 allows the water flowing into the fixed pipe 31 from the pressure limiting point to flow along the inner wall of the fixed pipe 31 to the grinding disc 32, and to gather and flow along the arcuate surface of the top side of the grinding disc 32 toward the inner hole of the grinding disc 32, thereby preventing some water from adhering to the top side of the grinding disc 32 and being unable to circulate in real time with the water flow. After the above-mentioned medicinal powder flows into the inner hole of the grinding disc 32, due to the push of the air flow and the water flow, the medicinal powder particles slide along the arcuate surface of the grinding plate 34 into the gap between the grinding disc 32 and the grinding plate 34, and the rotating grinding disc 32 grinds the medicinal powder particles. There is always a strong resistance between the medicinal powder particles and the grinding disc 32 and the grinding plate 34, thereby enhancing the grinding effect of the grinding disc 32 on the medicinal powder.

[0051] In a further preferred embodiment of the present invention, Figure 4 and Fig.10 As shown, a plurality of scrapers 37 are fixedly mounted on the top side of the grinding disc 32 in a circumferential array, and the bottom of the scraper 37 contacts the inner wall of the fixed tube 31, and the top of the scraper 37 is fixedly connected to the impeller 36;

[0052] In this embodiment, during the rotation of the grinding disc 32 , the impeller 36 can be driven to rotate synchronously by the scraper 37 , and the rotating scraper 37 slides along the inner wall of the fixed tube 31 to scrape off the water attached to the inner wall of the fixed tube 31 , thereby accelerating the rate at which the water falls onto the grinding disc 32 .

[0053] In a further preferred embodiment of the present invention, Figure 3 , Figure 6 and Fig.11 As shown, the medicine spreading mechanism 4 includes a guide shell 41, which is rotatably sleeved on the bottom end of the grinding disc 32, and the bottom end opening of the guide shell 41 is located at the center of the inner bottom wall of the water storage cylinder 1 and is in clearance with the inner wall of the water storage cylinder 1, and the support rod 38 is fixedly passed through the shell wall of the guide shell 41;

[0054] In this embodiment, the gas and liquid medicine discharged from the gap between the grinding disc 32 and the grinding plate 34 are discharged into the water storage cylinder 1 from the center position of the inner bottom wall of the water storage cylinder 1 due to the constraint of the guide shell 41, and the inner bottom wall of the water storage cylinder 1 can be continuously flushed to avoid the generation of medicine precipitation on the inner bottom wall of the water storage cylinder 1, which affects the mixing of medicine powder and water.

[0055] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 and Figure 8As shown, a partition plate 42 is provided above the guide shell 41, and the partition plate 42 is fixedly sleeved on the outer peripheral side of the bottom of the grinding disc 32, and the outer peripheral wall of the partition plate 42 is rotatably connected to the inner wall of the water storage cylinder 1 through a bearing, and a plurality of drainage holes 43 are opened on the partition plate 42 in a circumferential array, and a soft ring 44 is sleeved on the outer peripheral sides of the grinding disc 32 and the grinding plate 34, and the top inner ring wall of the soft ring 44 is fixedly connected to the grinding disc 32, and the bottom inner ring wall of the soft ring 44 is in contact with the outer peripheral wall of the grinding plate 34;

[0056] In this embodiment, during the process of the water flowing into the water storage cylinder 1, due to the obstruction of the soft ring 44, the water will hardly flow into the fixed cylinder through the gap between the grinding disc 32 and the grinding plate 34, thereby preventing the water in the water storage cylinder 1 from flowing into the fixed cylinder through the gap between the grinding disc 32 and the grinding plate 34;

[0057] The water or gas discharged from the bottom opening of the guide shell 41 is limited in the amount of liquid discharged from the combination of the partition 42 and the drainage hole 43, and the liquid injected into the water storage cylinder 1 is diffused from the center of the bottom wall of the water storage cylinder 1 to the surroundings, thereby enhancing the flushing effect of the inner wall of the water storage cylinder 1.

[0058] When the gas and liquid medicine are flushing the bottom wall of the water storage cylinder 1, part of the liquid medicine and all of the gas are diverted into multiple small air flows and small liquid medicine flows that pass through the drainage hole 43 and cross the partition 42. At the same time, the grinding disc 32 rotates while synchronously driving the partition 42 to rotate, so that the small air flows and small liquid medicine flows discharged from the drainage hole 43 are discharged upward from various places of the partition 42, and the liquid medicine is sprinkled into the water above the partition 42. Combined with the circulating flow of water in the water storage cylinder 1 and the fixed pipe 31, the medicine in the water can quickly diffuse and mix with the water. At the same time, the flow of the air flow in the water above the partition 42 can stir the water in the water storage cylinder 1, further accelerating the diffusion rate of the medicine in the water.

[0059] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the driving mechanism 5 includes a gear ring 51, which is fixedly sleeved on the outer peripheral side of the grinding disc 32, and the gear ring 51 is located between the partition 42 and the guide shell 41. A driver 52 is fixedly installed on the bottom side of the water storage cylinder 1, and the driver 52 is located on the outer peripheral side of the electric control drain valve 7. A gear 53 is meshingly installed on the outer peripheral side of the gear ring 51, and the driving end of the driver 52 rotates through the cylinder wall of the water storage cylinder 1 and is fixedly connected to the gear 53. A protective shell 54 is sleeved on the outer peripheral side of the gear ring 51 and the gear 53, and the protective shell 54 is rotatably sleeved on the outer peripheral side of the grinding disc 32, and the protective shell 54 is clearance-matched with the guide shell 41 and the partition 42;

[0060] In this embodiment, when the above device is used, the driver 52 starts the driving gear 53 to rotate at a constant speed, thereby driving the grinding disc 32 to rotate rapidly through the gear ring 51, and the gear 53 and the gear ring 51 are always located in the protective shell 54 to rotate, thereby isolating the gear 53 and the gear ring 51 from contact with water, thereby preventing water from corroding the gear 53 and the gear ring 51, and extending the service life of the gear 53 and the gear ring 51;

[0061] It should be noted that three sealing rings are fixedly installed in the shell wall of the above-mentioned protective shell 54 at the position corresponding to the grinding disc 32 and at the position corresponding to the driving end of the driver 52, and the inner ring walls of the three sealing rings are in contact with the outer peripheral wall of the grinding disc 32 and the outer peripheral wall of the driving end of the driver 52 respectively.

[0062] In a further preferred embodiment of the present invention, Figure 2 , Figure 4 , Figure 5 , Fig.12 and Fig.13 As shown, the dosing component 2 includes a dosing tube 21, which rotates and passes through the impeller 36, and the bottom end of the dosing tube 21 is gap-matched with the grinding disc 32, and the top end of the dosing tube 21 is fixed to pass through the wall of the water storage cylinder 1, and a spiral blade 22 is provided in the bottom opening of the dosing tube 21, and a hexagonal rod 23 is fixedly installed at the bottom end of the spiral blade 22, and the bottom end of the hexagonal rod 23 is inserted into the top opening of the inner hole of the grinding disc 32 and is fixedly connected to the inner hole wall of the grinding disc 32 through a plurality of connecting rods, and the hexagonal rod 23 is gap-matched with the grinding plate 34, and the outer peripheral side sliding sleeve of the hexagonal rod 23 is provided with a sealing plate 24, and the top side of the sealing plate 24 is an arc-shaped setting that bulges upward at the center position and contacts the inner wall of the bottom opening of the dosing tube 21, and the outer peripheral side fixed sleeve of the hexagonal rod 23 is provided with a limiting ring 25, and a spring 26 is provided between the limiting ring 25 and the sealing plate 24, and the upper and lower ends of the spring 26 are respectively fixedly connected to the sealing plate 24 and the limiting ring 25;

[0063] In this embodiment, during the rotation of the grinding disc 32, the sealing plate 24 and the spiral blade 22 can be driven to rotate synchronously by the hexagonal rod 23, and the rotating spiral blade 22 pushes the powder in the dosing tube 21 downward. At this time, due to the push of the powder, the sealing plate 24 slides along the hexagonal tube to compress the spring 26, so that a certain amount of gap is formed between the sealing plate 24 and the inner wall of the bottom opening of the dosing tube 21, so that the powder in the dosing tube 21 leaks out of the dosing tube 21 along the arc surface of the sealing plate 24 at a uniform speed. During the rotation of the sealing plate 24, the powder can be sprinkled to the surroundings by centrifugal force, so that the powder falls on the top side of the grinding disc 32 more evenly, and then the powder is gradually taken away by the flushing of the arc surface of the top side of the grinding disc 32 by the flow of water or air, so that the powder will not be accumulated together in large quantities, thereby reducing the probability of powder agglomeration after water and powder come into contact.

[0064] In a further preferred embodiment of the present invention, Figure 2and Figure 4 As shown, a storage hopper 27 is provided at the center of the top of the water storage cylinder 1, and the electric-controlled water inlet valve 6 is located on the outer peripheral side of the storage hopper 27, the discharge end of the storage hopper 27 is connected and installed with the top opening of the dosing tube 21, and a sealing cover 28 is installed with an internal thread of the top opening of the storage hopper 27, and a filter plate 29 is fixedly installed at the center of the sealing cover 28;

[0065] In this embodiment, when using the device, the operator screws the cover 28 out of the storage hopper 27, then pours the powder into the storage hopper 27, and then screws the cover 28 back into the top opening of the storage hopper 27 to close the top opening of the storage hopper 27. The powder feeding operation is completed, and the operator can open or close the electric control valve on the storage hopper 27 to continuously inject a specific amount of powder into the dosing tube 21, thereby reducing the frequency of the operator's powder dosing and further reducing the operator's work intensity.

[0066] It should be noted that the discharge end of the storage hopper 27 is equipped with an electrically controlled valve.

[0067] Working principle: When the improved water treatment intelligent dosing device is used, the operator first screws the cover 28 out of the storage hopper 27, then pours the powder into the storage hopper 27, and then screws the cover 28 back into the top opening of the storage hopper 27 to close the top opening of the storage hopper 27, and the powder feeding operation is completed;

[0068] After the powder feeding operation is completed, the operator starts the control device through the control panel. First, the electric water inlet valve 6 is opened, and the water in the water input pipe flows into the water storage cylinder 1 through the electric water inlet valve 6. After the water level sensor detects that the water in the water storage cylinder 1 reaches the threshold, the electric water inlet valve 6 is closed. At this time, a certain amount of water is stored in the water storage cylinder 1, and the water level exceeds a group of pressure limiting valves 35 on the bottom side. The injection of water into the water storage cylinder 1 is completed;

[0069] It should be noted that, in the process of the water flowing into the water storage cylinder 1, due to the obstruction of the soft ring 44, the water will hardly flow into the fixed cylinder through the gap between the grinding disc 32 and the grinding plate 34;

[0070] When water is injected into the water storage cylinder 1, the electric control valve on the storage hopper 27 opens, and the powder in the storage hopper 27 slides into the dosing tube 21 along the inner wall of the storage hopper 27. At this time, due to the push of the spring 26 on the sealing plate 24, the top curved surface of the sealing plate 24 and the bottom inner wall of the dosing tube 21 are tightly fitted to close the bottom opening of the dosing tube 21, so that the powder falling into the dosing tube 21 is stored in the dosing tube 21 until the dosing tube 21 is filled with powder. When the above-mentioned electric control water inlet valve 6 is closed, the electric control valve on the water storage cylinder 1 is closed synchronously, and a fixed amount of powder is stored in the dosing tube 21.

[0071] It should be noted that when the medicine powder in the storage hopper 27 slides into the dosing tube 21, the external gas simultaneously passes through the filter plate 29 and flows into the storage hopper 27, so that there is no negative pressure cavity in the storage hopper 27 to affect the medicine powder sliding into the dosing tube 21, and at the same time, the dust particles and debris in the gas will also be blocked outside the storage hopper 27 by the filter plate 29;

[0072] After the above-mentioned feeding operation of the medicine powder and water is completed, the driver 52 starts the driving gear 53 to rotate at a constant speed, thereby driving the grinding disc 32 to rotate rapidly through the gear ring 51, and the rotating grinding disc 32 synchronously drives the impeller 36 to rotate through the scraper 37, and the rotating impeller 36 pushes the gas in the fixed pipe 31 downward, so that the gas passes through the inner hole of the grinding disc 32 and the gap between the grinding disc 32 and the grinding plate 34 and is discharged from the fixed pipe 31. When the impeller 36 pushes the gas in the fixed pipe 31 out, a negative pressure cavity is formed at the top of the fixed pipe 31. At this time, a pressure difference is continuously formed at both ends of the pressure limiting valve 35, and the water storage cylinder 1 The gas in the water storage cylinder 1 flows into the fixed pipe 31 through the pressure limiting valve 35 on the top side to replenish the gas lost in the fixed pipe 31, and the water at the top of the water storage cylinder 1 flows into the fixed pipe 31 from the next group of pressure limiting valves 35 to replenish another part of the gas lost in the fixed pipe 31. The water flowing into the fixed pipe 31 from the pressure limiting valve 35 flows downward along the pressure limiting valve 35 along the pipe wall of the fixed pipe 31, and finally passes through the inner hole of the grinding disc 32 and the gap between the grinding disc 32 and the grinding plate 34 to be discharged from the fixed pipe 31, so that the gas and water are continuously discharged from the inner hole of the grinding disc 32 and the gap between the grinding disc 32 and the grinding plate 34.

[0073] It should be noted that when the gas is discharged from the gap between the grinding disc 32 and the grinding plate 34, the soft ring 44 is stretched and deformed synchronously due to the push of the airflow and water on the soft ring 44, and the blocking state of the gap between the grinding disc 32 and the grinding plate 34 is automatically released;

[0074] During the rotation of the grinding disc 32, the hexagonal rod 23 can drive the sealing plate 24 and the spiral blade 22 to rotate synchronously, and the rotating spiral blade 22 pushes the powder in the dosing tube 21 downward. At this time, the sealing plate 24 slides along the hexagonal tube due to the push of the powder to compress the spring 26, so that a certain amount of gap is formed between the sealing plate 24 and the inner wall of the bottom opening of the dosing tube 21, so that the powder in the dosing tube 21 leaks out of the dosing tube 21 along the arc surface of the sealing plate 24 at a uniform speed. During the rotation of the sealing plate 24, the powder can be sprinkled around by centrifugal force, so that the powder falls on the top side of the grinding disc 32 more evenly, and then the powder is gradually taken away by the scouring of the arc surface of the top side of the grinding disc 32 by the flow of water or air.

[0075] It should be noted that when the rotation speed of the grinding disc 32 changes, the negative pressure strength at the top of the fixed pipe 31 increases or decreases synchronously due to the decrease or reduction in the airflow driven by the impeller 36, so that the amount of gas or water flowing into the fixed pipe 31 increases or decreases synchronously. At the same time, due to the increase or decrease in the rotation speed of the grinding disc 32, the rotation speed of the spiral blade 22 also increases or decreases synchronously, thereby causing the speed at which the spiral blade 22 pushes the powder downward to increase or decrease synchronously. At this time, due to the push of the powder and the spring 26 on the sealing plate 24, the size of the gap between the sealing plate 24 and the inner bottom wall of the dosing tube 21 also increases or decreases synchronously, and finally the amount of powder spilled in the dosing tube 21 can be automatically adjusted;

[0076] When the above-mentioned medicine powder enters the gap between the grinding mill and the grinding plate 34, the rotation between the grinding disc 32 and the grinding plate 34 can grind the lumps and medicine powder in the medicine powder into finer powders, and make the water and the medicine powder fully contact, and at the same time, the medicine powder will not form lumps when it contacts with water, and finally make the medicine powder fully dissolved in water, and the medicine liquid with high concentration is continuously discharged from the outer peripheral side of the gap between the grinding disc 32 and the grinding plate 34;

[0077] The gas and liquid medicine discharged from the gap between the grinding disc 32 and the grinding plate 34 are discharged into the water storage cylinder 1 from the center of the inner bottom wall of the water storage cylinder 1 due to the constraint of the guide shell 41. Then, due to the combination of the partition plate 42 and the limited amount of liquid discharged from the drainage hole 43, the liquid medicine injected into the water storage cylinder 1 diffuses from the center of the inner bottom wall of the water storage cylinder 1 to the surroundings, flushing the inner bottom wall of the water storage cylinder 1, so that no sediment is generated on the inner bottom wall of the water storage cylinder 1.

[0078] When the gas and liquid medicine are flushing the bottom wall of the water storage cylinder 1, part of the liquid medicine and all of the gas are divided into multiple small air flows and small liquid medicine flows passing through the drainage hole 43 and over the partition 42. At the same time, the grinding disc 32 rotates while synchronously driving the partition 42 to rotate, so that the small air flow and small liquid medicine flow discharged from the drainage hole 43 are discharged upward from various places of the partition 42, and the liquid medicine is sprinkled into the water above the partition 42. With the circulation of water in the water storage cylinder 1 and the fixed pipe 31, the medicine in the water quickly diffuses and mixes with the water. At the same time, the flow of the air flow in the water above the partition 42 can stir the water in the water storage cylinder 1, further accelerating the diffusion rate of the medicine in the water.

[0079] As the spiral blade 22 rotates, the fixed amount of powder in the fixed tube 31 gradually leaks out of the fixed tube 31 until the powder in the fixed tube 31 is emptied. At this time, the driver 52 is continuously driven to continuously stir the water through the circulation of water in the water storage cylinder 1 and the fixed tube 31, thereby accelerating the diffusion rate of the drug in the water.

[0080] After the medicine and water are mixed, the electric-controlled drain valve 7 is started, and the water in the water storage cylinder 1 gradually gathers toward the electric-controlled drain valve 7 along the inner bottom of the water storage cylinder 1, and is discharged from the water storage cylinder 1 through the electric-controlled drain valve 7. After the water in the water storage cylinder 1 is discharged, the electric-controlled drain valve 7 is closed, and then the electric-controlled water inlet valve 6 is opened. According to the above repeated operations, the water can be continuously treated with medicine.

[0081] Embodiment 2: A dosing method, including the above-mentioned intelligent dosing device for water treatment, specifically includes the following steps:

[0082] Step 1: The operator twists the cover 28 out of the storage hopper 27, and directly pours the powder into the storage hopper 27 to complete the operation of adding the powder into the storage hopper 27;

[0083] Step 2: The operator starts the device, and water flows into the water storage cylinder 1 from the electrically controlled water inlet valve 6 until the water level in the water storage cylinder 1 overflows a set of pressure limiting valves 35 at the bottom. At the same time, the powder slides from the storage hopper 27 into the dosing tube 21 to fill the dosing tube 21. The water and powder feeding operation is completed.

[0084] Step 3: After the feeding operation in step 2 is completed, the driving mechanism 5 drives the grinding disc 32 and the impeller 36 to rotate continuously, so that the water and gas in the water storage cylinder 1 circulate in the water storage cylinder 1 and the fixed pipe 31, and at the same time, the dosing component 2 sprinkles the powder into the water flow, so that the powder and water are fully mixed;

[0085] Step 4: After the medicine powder and water are fully mixed, the sewage in the water storage cylinder 1 after the medicine is added is discharged from the electric control drain valve 7, and the water adding operation can be completed continuously by repeating the above operation;

[0086] In this embodiment, the device is highly intelligent, and the operator only needs to regularly add the medicine powder into the storage hopper 27, which can greatly reduce the labor intensity of the user.
