[0070] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0071] like Figure 1 As shown in the figure, this application provides an automatic dosing device, which includes at least a feeding device, a first storage device 10, a second quantitative storage device 20, a mixing device 30, and a water inlet pipe 52.

[0072] The aforementioned first storage device 10 has a first storage space 11 inside. The top of the first storage device 10 is provided with a feeding port 12 for connecting and communicating with a feeding device. The feeding port 12 can also be connected to the feeding device through a feeding pipe 51. The bottom of the first storage device 10 is provided with a first discharge port 13. Both the feeding port 12 and the first discharge port 13 are connected to the first storage space 11. The first discharge port 13 is provided with a first valve 14 that can open and close the first discharge port 13. Specifically, the first valve 14 can be a slide gate valve. The slide gate extends to block the first discharge port 13, and the slide gate retracts to open the first discharge port 13. For convenient control, an automatic electric control valve can also be used.

[0073] The aforementioned second quantitative storage device 20 has a second storage space 21 inside. It should be noted that the volume of the second storage space 21 is much smaller than the volume of the first storage space 11. The volume of the second storage space 21 is sufficient to store the amount of material for each quantitative dosing, while the first storage space 11 of the first storage device 10 needs to be a large storage space to reduce the number of times staff need to add or load materials, reduce labor intensity, and lower labor costs. Furthermore, the second quantitative storage device 20 is provided with a first inlet 22 connected to the first outlet 13 of the aforementioned first storage device 10, and also has a second outlet 23. Both the first inlet 22 and the second outlet 23 communicate with the second storage space 21.

[0074] Furthermore, the aforementioned second quantitative storage device 20 is also equipped with a first metering device for quantitatively receiving a predetermined amount of storage material from the first storage device 10. Preferably, the first metering device is a continuous metering device 24, and more preferably a volumetric continuous metering device. By measuring the volume of the material received into the second storage space 21 of the second quantitative storage device 20, the existing amount of storage material is determined to reach the predetermined amount of storage material, thereby temporarily closing the first valve 14 and discharging the material through the second outlet 23 into the mixing space 31 of the mixing device 30, thereby achieving precise control of the dosage.

[0075] The aforementioned mixing device 30 has a mixing space 31 inside. The mixing device 30 is provided with a first inlet 32 ​​connected to the second outlet 23 of the aforementioned second quantitative storage device 20, a second inlet 33 connected to the aforementioned water inlet pipe 52, and a first medicine outlet 34. Specifically, the water inlet of the water inlet pipe 52 can be connected to a tap water connection pipe to introduce tap water. The water inlet pipe 52 is provided with a flow meter to measure the amount of water added in order to accurately control the amount of water added. Specifically, the flow meter can be an electromagnetic flow meter 521 for convenient automatic measurement.

[0076] Compared with the prior art, the automatic dosing equipment provided in this application embodiment includes at least a feeding device, a first storage device 10, a second quantitative storage device 20, a mixing device 30, and a water inlet pipe 52. The feeding device feeds the first storage device 10 through a feeding port 12 connected to it. A first discharge port 13 at the bottom of the first storage device 10 is connected to the first inlet port 22 of the second quantitative storage device 20, and the first discharge port 13 is provided with a first valve 14. The second quantitative storage device 20 is also provided with a first metering device for quantitatively receiving a predetermined amount of storage material from the first storage device 10. When the storage material reaches the predetermined value, the first valve 14 is automatically closed to stop feeding. The volume of the second storage space 21 of the material storage device 20 is much smaller than the volume of the first storage space 11 of the first storage device 10. The second quantitative storage device 20 is responsible for precise quantitative control of the dosage. The quantitatively controlled material is then fed into the mixing space 31 of the mixing device 30 through its second outlet 23 and the first inlet 32 ​​of the mixing device 30. The mixing device 30 is also provided with a second inlet 33 connected to the water inlet pipe 52. Water is also fed into the mixing space 31 of the mixing device 30 through the water inlet pipe 52. The material and water are mixed in the mixing space 31 of the mixing device 30 and then discharged from the first outlet 34. The water inlet pipe 52 is equipped with a flow meter to accurately control the amount of water added.

[0077] This setup achieves two key advantages: First, it enables precise control of both the dosage and water volume, allowing for accurate measurement and management of both. Second, since the volume of the second storage space 21 of the second quantitative storage device 20 is much smaller than the volume of the first storage space 11 of the first storage device 10 (which is relatively large), and the second quantitative storage device 20 can continuously and automatically add dosages, workers are no longer required to frequently add dosages to the first storage device 10, significantly reducing labor costs and worker workload.

[0078] In a preferred embodiment, the aforementioned first storage device 10 may also be equipped with a second metering device for measuring the amount of material stored in the first storage device 10, so as to be able to know the amount of material stored in the first storage device 10 in real time, and when the remaining amount is about to be insufficient, the staff can start the feeding device to feed the material in time.

[0079] Specifically, such as Figure 1 As shown, the second metering device may include multiple weight sensors 15 evenly arranged around the bottom circumference of the first storage device 10. Two, three, four or more sensors may be evenly arranged at intervals. Measuring is performed by weight measurement, which has higher reliability. Each weight sensor is electrically connected to the control terminal for data transmission, transmitting the weight measurement data to the control terminal in real time for easy viewing by staff. The control terminal may also be equipped with a prompting module. When the remaining amount in the first storage space 11 of the first storage device 10 is about to run out, the prompting module may issue a notification or alarm to notify the staff to add material in time.

[0080] More specifically, the upper middle part of the aforementioned first storage device 10 can be configured as a cylindrical structure, and the bottom can be configured as a funnel-shaped structure with a gradually decreasing diameter from top to bottom. The weight sensors 15 can be evenly and spaced on the inclined sidewall of the funnel-shaped structure on the same horizontal plane.

[0081] A preferred embodiment is, as follows: Figure 1 As shown, the automatic dosing device provided in this application embodiment may further include a dissolving device 40, which is connected to the aforementioned mixing device 30. The dissolving device 40 includes a dissolving pump 41 and a dissolving chamber 42 connected to the dissolving pump 41. The dissolving pump 41 is a high-speed pressurized pump, and the dissolving chamber 42 is also connected to the first drug outlet 34 of the mixing device 30. The dissolving chamber 42 is provided with a second drug outlet 43, which is connected to the drug outlet pipe 53, so as to achieve further high-speed pressurized dissolution after the drug and water are mixed, so that the drug and water are dissolved and mixed more evenly, and then the drug is discharged from the drug outlet pipe 53, thereby improving the dosing effect.

[0082] Furthermore, the aforementioned dissolving chamber 42 is also provided with a drain outlet 44, which is connected to a drain pipe 54 to discharge waste and impurities. The drain pipe 54 leads to a drainage ditch, wastewater treatment, etc.

[0083] One specific embodiment is, as follows: Figure 1 As shown, the upper part of the aforementioned mixing device 30 can be configured as a cylindrical structure, and the lower part can be configured as a funnel-shaped structure with a gradually decreasing diameter from top to bottom. Specifically, the first inlet 32 ​​can be located at the top of the upper cylindrical structure, the second inlet 33 can be located on the side wall of the cylindrical structure, and the first drug outlet 34 can be located at the bottom of the lower funnel-shaped structure.

[0084] Preferably, the top or side wall of the upper cylindrical structure of the aforementioned mixing device 30 may be provided with an overflow port 35 connected to the overflow pipe 55 to discharge the medicine overflowing from the mixing device 30. The overflow pipe 55 and the aforementioned sewage pipe 54 are connected to a drainage device and eventually lead to a drainage ditch, wastewater treatment, etc.

[0085] Another specific embodiment is that the aforementioned water inlet pipe 52 may be equipped with a first solenoid valve 522, the aforementioned medicine outlet pipe may be equipped with a second solenoid valve 531, and the aforementioned sewage outlet pipe may be equipped with a third solenoid valve 541, so as to realize automatic control of opening and closing.

[0086] In an optional embodiment, the aforementioned first storage device 10 may further be equipped with a stirrer 17, the stirring rod 171 of which can extend into the first storage space 11 of the first storage device 10 to stir, thereby preventing the medicinal material in the first storage space 11 from solidifying, hardening, or clumping, and maintaining a uniform state through stirring. Furthermore, the bottom of the first storage device 10 may also be equipped with a vibrator 16 to agitate the medicinal material in the first storage space 11 through vibration, further preventing the medicinal material from solidifying, hardening, or clumping, and maintaining a uniform state.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
