The dosing box 1 is provided with a powder box 2, and the powder medicine is placed in the powder box 2. The specific powder box 2 is funnel-shaped, wide at the top and narrow at the bottom, so that the powder medicine is automatically discharged toward the bottom. The interior of the dosing box 1 is connected in sequence with a mixing tank 3, a maturation tank 4, and a storage tank 5 with gradually increasing depths. The tops of the three are at the same height, and the heights of the bottoms are successively reduced, so that the liquid medicine can automatically flow backward along the depth direction. The three are connected by a connecting pipe, and an electromagnetic valve is provided on the connecting pipe to realize automatic control of the flow of the liquid medicine. A connected wetting tank 6 is provided above the mixing tank 3, and the wetting tank 6 is used to The powder is moistened to avoid agglomeration and precipitation when the powder is directly mixed with solvent water. A spiral feeding tube 7 is provided at the bottom of the powder box 2. The spiral feeding tube 7 uses a rotating shaft to drive the spiral blade to rotate, so that the powder dropped from the bottom of the powder box 2 is gradually discharged, and the control of the discharge amount is more accurate. The spiral feeding tube 7 extends to the interior of the wetting tank 6 to achieve gradual addition of the powder for accurate dispersion. A spray plate 8 is provided on the top of the wetting tank 6. The cross section of the spray plate 8 is adapted to the cross section of the wetting tank 6, so that the solvent water sprayed therefrom can be evenly dispersed at various positions of the wetting tank 6. Such a structure allows the powder to be dispersed and mixed with the solvent water sprayed by the spray plate 8 when entering the interior of the wetting tank 6, thereby fully wetting the powder, further The step reduces the situation that the powder forms large lumps. The bottom of the wetting tank 6 is provided with a filter screen 9. The wetted powder passes through the filter screen 9 and falls into the mixing tank 3 below. If there are large lumps, they are blocked on the filter screen 9. The lumps are dissolved by the continuous spraying of the subsequent spray disk 8, so that the wetting effect of the powder is further improved. The mixing tank 3 is connected to the stirring shaft 10 through the bearing rotation. The stirring shaft 10 is driven to rotate by a motor. A plurality of stirring rods 11 are distributed on the stirring shaft 10 in an array fixed by welding or bolts. The stirring rod 11 is driven to rotate by the stirring shaft 10, so that when the solvent water is added to the mixing tank 3, it is better stirred and mixed with the wetted medicine, thereby completing the mixed dissolution of the medicine. This mixed dissolution method The concentration of the formed medicine is more uniform, and it is not easy to precipitate or agglomerate. A heating pipe is provided at the bottom of the maturation tank 4. The mixed medicine flows into the maturation tank 4 through the connecting pipe. The heating pipe is used to provide a certain temperature to it, so that the various medicine components can be better integrated and reacted in the maturation tank 4, ensuring the best mixing and processing effect. The medicine storage tank 5 is connected with a dosing pipe 12. The matured medicine flows into the medicine storage tank 5 through the connecting pipe for storage, and is discharged through the dosing pipe 12 when dosing is needed. A metering pump 13 is provided on the dosing pipe 12. The metering pump 13 automatically adds a specified amount of medicine to the circulating water by pumping out, thereby realizing automatic dosing of the prepared medicine. Such a structure makes the concentration of the prepared medicine more uniform.The fusion and reaction between the various components of the reagents are more complete, which greatly improves the treatment effect of the circulating water, reduces the impurity content of the circulating water when it enters the reverse osmosis device, reduces the flushing frequency of the reverse osmosis, extends its service life, and greatly reduces the treatment cost of the circulating water.
[0024] Preferably, refer to Figure 5 The mixing tank 3 is provided with a water inlet pipe 14, and the water inlet amount of the water inlet pipe 14 is controlled by a metering water pump. The water inlet pipe 14 is provided with a connected water inlet branch pipe 15, and the water inlet branch pipe 15 is connected to the spray plate 8. Such a structure allows a part of the added solvent water to be combined with the medicine powder in advance for wetting, and the remaining solvent water is mixed with the wetted medicine powder again in the mixing tank 3, thereby ensuring that the total amount of added solvent water is more accurate and the accuracy of the concentration of the prepared medicine is ensured.
[0025] Preferably, refer to Figure 3 and Figure 4 The stirring shaft 10 passes through the wetting tank 6 and extends into the mixing tank 3. The part of the stirring shaft 10 located in the wetting tank 6 is fixed with a scraper 16 by welding or bolts. The scraper 16 is in rotational contact with the top of the filter screen 9. Such a structure allows the stirring shaft 10 to rotate while driving the stirring rod 11 and the scraper 16 to rotate, so that the scraper 16 quickly breaks up the residual powder lumps on the filter screen 9 and mixes them with the solvent water, thereby avoiding the residue of powder in the wetting tank 6 and ensuring the accuracy of the powder addition amount.
[0026] Preferably, refer to Figure 6 The heating tube includes a horizontally arranged inner ring tube 17 and an outer ring tube 18, both of which are electric heating tube structures. A plurality of vertically arranged arched tubes 19 are provided between the inner ring tube 17 and the outer ring tube 18. The two ends of the bottom of the arched tube 19 are respectively connected to the inner ring tube 17 and the outer ring tube 18. Such a structure enables the inner ring tube 17 and the outer ring tube 18 to perform basic heating operations at the bottom, and the plurality of array-distributed arched tubes 19 are heated at various positions within the vertical range. Such a structure makes the heating speed faster and the temperature at various positions more uniform, further improving the efficiency of mixing and reaction of various components in the medicine and accelerating the efficiency of medicine maturation.
[0027] Preferably, a plurality of liquid outlet pipes 20 are respectively provided at different heights of the medicine storage tank 5, and the plurality of liquid outlet pipes 20 are all connected to the dosing pipe 12. Such a structure enables the medicine pumped out by the metering pump 13 to come from different heights in the medicine storage tank 5, thereby effectively avoiding the situation where the medicine powder may be deposited at the bottom and cause uneven concentration of subsequent medicine addition, further ensuring the uniformity and accuracy of the medicine concentration.
[0028] Preferably, the bottom of the wetting tank 6 is a cone that is wide at the top and narrow at the bottom. This structure allows the wetted medicine to be more concentrated at the bottom of the wetting tank 6, making it less likely to adhere to and aggregate on the side walls, thereby avoiding powder residue and ensuring the accuracy of the powder addition amount.

The powdered medicine in the medicine powder box 2 enters the wetting tank 6 through the spiral feeding pipe 7, and the medicine powder is wetted by the spraying disk 8 on the top of the wetting tank 6 and then passes through the filter screen 9 and falls into the mixing tank 3. The stirring rod 11 is driven to rotate by the stirring shaft 10 to make it better stirred and mixed with the solvent water. Such a structure makes it difficult for the medicine powder to form lumps or precipitation during the mixing process, improves the uniformity of the dissolution and mixing of the medicine powder, thereby making the distribution of the medicine powder more uniform, ensuring the concentration of the medicine, and improving the treatment effect of the circulating water; the medicine adding box 1 is also connected in sequence with depth-by-depth mixing devices. The maturation tank 4 and the medicine storage tank 5 are gradually enlarged, and the mixed medicine automatically flows into the maturation tank 4. The medicine is matured for a certain time at a certain temperature through the heating tube, so that the different powder components therein can be better fused and reacted, thereby further improving the treatment effect of the formed medicine. The matured medicine automatically flows into the medicine storage tank 5 for storage, and the metering pump 13 is used to automatically add the medicine liquid in the medicine storage tank 5 to the circulating water, which greatly improves the convenience of adding medicine, improves the treatment effect of the circulating water, reduces the amount of impurities in the circulating water when flowing through the reverse osmosis device, reduces the flushing frequency of the reverse osmosis device, and improves the service life of the reverse osmosis device.
