[0019] Figure 2 This is a structural principle diagram of a dosing device provided in an embodiment of this specification. DETAILED DESCRIPTION

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0021] like Figure 1 and 2As shown, this embodiment provides a dosing device, including a box body 1, a dosing hopper 2, a dry powder dissolver 3, a water inlet pipe 4, a water outlet pipe 5, and a stirrer 6. The water inlet pipe 4 is provided with two branches, one of which is connected to the box body 1 and the other is connected to the dry powder dissolver 3. The discharge end of the dosing hopper 2 is connected to the dry powder dissolver 3, and the discharge end of the dry powder dissolver 3 is connected to the box body 1; two groups of guide plates are provided in the box body 1, which divide the box body 1 into three chambers 11, and each chamber 11 is provided with a stirrer 6. Each group of guide plates includes two guide plates 12 respectively connected to the upper and lower ends of the box body 1, and a guide channel 13 is formed between the two guide plates 12. The inlet and outlet of the guide channel 13 are respectively located at the lower end and the upper end; the dry powder dissolver 3 and the water inlet pipe 4 are connected Figure 2 The upper end of the first chamber on the left side of the middle chamber, the outlet pipe 5 is connected to the lower end of the third chamber. Among them, the stirrer 6 adopts a conventional blade stirrer, which will not be described here. The working principle of this dosing device is as follows: Figure 2 Water and a preliminarily dissolved agent are injected into the first chamber of the housing 1 through the water inlet pipe 4 and the dry powder dissolver 3, respectively, in the upper middle left corner. After being stirred by the agitator 6 in the first chamber, the agent passes through the diversion channel 13 from the lower end and flows into the second chamber from the upper end. The above action is repeated until the diluted agent, after being stirred by the agitator in the third chamber, enters the water outlet pipe 5 and is injected into the pipeline mixer of the water purification equipment through the water outlet pipe 5 to act on the raw water to be purified. This embodiment mainly increases the path length of the water flow within the limited housing 1 by adding a diversion channel 13 between adjacent chambers, thereby further improving the mixing effect of the agent and water and improving the water purification effect.

[0022] like Figure 2 As shown, due to the setting of the above-mentioned diversion channel 13, only when the liquid levels in the first two chambers are higher than the outlet at the upper end of the diversion channel 13, will the medicine enter the third chamber. Therefore, if the medicine is only output through the third chamber, when the dosage exceeds the injection volume at the upper left of the box body 1 for a long time, the liquid level in the third chamber will continue to drop until the dosage can no longer be met. Therefore, a valve 7 is provided between the lower end of each chamber 11 and the water outlet pipe 5. Under normal circumstances, only the valve at the lower end of the third chamber is opened to ensure the mixing effect of the medicine and water; when the above situation occurs, it is necessary to open the second chamber, or even the valve at the lower end of the first chamber, to sacrifice a certain mixing effect to meet the dosage. Accordingly, a liquid level gauge 8 is provided in the third chamber to monitor the liquid level so that the above-mentioned adjustments can be made in a timely manner.

[0023] Furthermore, under normal circumstances, the medicine is only output through the valve at the lower end of the third chamber, and due to the setting of the diversion channel 13, the sediment impurities generated in the first two chambers cannot all enter the third chamber, so some sediment impurities will accumulate at the bottom of the first two chambers. Figure 2The right end of the middle outlet pipe 5 is a water outlet 51, which is connected to the pipeline mixer of the water purification equipment, while the left end is a sewage outlet 52. When sewage needs to be discharged, the valve between the outlet pipe 5 and the pipeline mixer can be closed, and the valve at the sewage outlet 52 and the valve 7 between the three chambers 11 and the outlet pipe 5 can be opened to completely drain the sediment and impurities at the bottom of the chamber. To reduce the generation of sediment and impurities in the chamber, a filter 45 is provided on the water inlet pipe 4 to filter out as much impurities as possible in the water.

[0024] like Figure 2 As shown, both branches of the water inlet pipe 4 are equipped with regulating valves 41 for adjusting the flow rate of the two branches. In addition, a pressure-stabilizing valve 42 is provided on the water inlet pipe 4. Pressure-stabilizing valve 42 is connected to a pressure gauge 43 for regulating the inlet pressure to accurately control the inlet water volume. Accordingly, under the premise of stable inlet pressure, a flow meter 44 can be installed on the water inlet pipe 4 to monitor the inlet water volume.

[0025] like Figure 1 As shown, a material level observation window 21 is provided on the opposite side wall of the drug adding hopper 2 for observing the amount of drug in the drug adding hopper so as to add drug powder in time.

[0026] The present invention also provides an integrated water purification device, comprising a lift pump, a pipeline mixer, a flocculation tank, a sedimentation tank, a filter tank, a clear water tank, and a dosing device as described above. The outlet pipe 5 is connected to the pipeline mixer to inject the diluted reagent into the pipeline mixer. The overall structure and operating principle of this water inlet device are relatively conventional: raw water passes through the lift pump and enters the pipeline mixer, where it is fully mixed with the reagent. It then enters the flocculation tank for flocculation, then enters the sedimentation tank for precipitation of suspended matter. The supernatant enters the filter tank to filter out unsettled suspended matter, and the filtered water enters the clear water tank.

[0027] The above is only a preferred embodiment of the present invention, which is one implementation method based on the overall concept of the present invention. The scope of protection of the present invention is not limited to this embodiment. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
