[0002] Tap water refers to the water that is treated from a water source (such as a river, lake, groundwater, etc.) through a water supply system and then transported to households and other places. Tap water usually undergoes strict treatment and management to ensure that it meets the drinking water standards.

[0003] In the prior art, in order to improve the quality of tap water, generally, through the sedimentation process, sediment, plankton, and other solid particles in the water can be effectively removed to ensure cleaner water quality, and then through subsequent filtration and disinfection operations to improve the water quality. In the process of tap water treatment, adding a flocculant can promote the formation of larger particles of suspended matter in the water, but it is impossible to adjust the pH value of the water according to the properties of the water, which reduces the efficiency of the combination of impurities in the water and the flocculant, thereby increasing the sedimentation efficiency of tap water in the sedimentation device. Summary of the Utility Model

[0021] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1 - 4 shown, the present utility model provides a sedimentation device for tap water production, including an operating panel 1. A support 2 is fixedly installed on the top of the operating panel 1. A mixing tank 3 is fixedly installed on the top of the support 2. Two reagent tanks 4 are fixedly installed on one side of the outer wall of the mixing tank 3. The bottoms of the two reagent tanks 4 are both fixedly inserted with delivery pipes 5, and the output ends of the two delivery pipes 5 are both communicated with the inside of the mixing tank 3. Control valves 6 are fixedly installed on the outer surfaces of the two delivery pipes 5. A driving motor 7 is fixedly installed on one side of the outer wall of the mixing tank 3. A driving rod 8 is fixedly installed on one side of the outer wall of the driving motor 7. A plurality of stirring blades 9 are fixedly installed on the outer surface of the driving rod 8. A sedimentation tank 10 is fixedly installed on the top of the operating panel 1.

[0024] The effect achieved by the entire Example 1 is as follows: First, a certain amount of flocculant is added into the mixing tank 3. Since an acidic reagent and a basic reagent are respectively contained in the two reagent tanks 4, then according to the property of the water, the control valve 6 on the corresponding delivery pipe 5 is opened, so that the acidic reagent or the basic reagent enters the mixing tank 3 along the two delivery pipes 5. At this time, the drive motor 7 installed on one side of the outer wall of the mixing tank 3 is started, which drives the drive rod 8 and a plurality of stirring blades 9 to stir inside the mixing tank 3, causing the acidic reagent or the basic reagent to be fully mixed with the water and the flocculant. And through the action of this reagent, the efficiency of the combination of impurities in the water and the flocculant can be improved, so as to form flocs with a larger volume. Then the valve 12 is opened, and the pretreated tap water enters the sedimentation tank 10 along the outlet pipe 11, thereby improving the sedimentation efficiency of the tap water in the sedimentation tank 10.

[0025] Example 2: As Figures 2 - 4 shown, a water outlet pipe 11 is fixedly inserted on one side of the outer wall of the mixing tank 3, and the output end of the water outlet pipe 11 is communicated with the inside of the sedimentation tank 10. A valve 12 is fixedly installed on the outer surface of the water outlet pipe 11. Two reversible motors 13 are fixedly installed on one side of the outer wall of the sedimentation tank 10. On one side of the outer wall of the two reversible motors 13, threaded rods 14 are fixedly installed. On the other side of the outer wall of the sedimentation tank 10, two limiting blocks 15 are fixedly installed. The outer surfaces of the two threaded rods 14 are both movably inserted into the two limiting blocks 15. The outer surfaces of the two threaded rods 14 are both threadedly connected with connecting columns 16. A scraper 17 is fixedly installed between the bottoms of the two connecting columns 16. Two limiting grooves 18 are formed on the inner surface of the sedimentation tank 10. The inner surfaces of the two limiting grooves 18 are both movably embedded with limiting sliders 19. And on one side of the outer walls of the two limiting sliders 19, they are fixedly connected with the outer surface of the scraper 17. A sludge suction pump 20 is fixedly installed on the top of the operation panel 1, and one side of the outer wall of the sludge suction pump 20 is in contact with the opposite side of the outer wall of the sedimentation tank 10.

[0026] The effect achieved by the entire Example 2 is as follows: When the tap water has sedimented in the sedimentation tank 10 for a period of time, the tap water is pumped out and enters the next filtration or disinfection process. At this time, a large amount of sludge will accumulate in the sedimentation tank 10. Then the two reversible motors 13 are started, which drive the two threaded rods 14 to rotate inside the two limiting blocks 15. Since two limiting grooves 18 are formed on the inner surface of the sedimentation tank 10, the limiting sliders 19 installed on both sides of the scraper 17 are both movably embedded in the two limiting grooves 18, and the scraper 17 is installed at the bottom of the two connecting columns 16. Therefore, by moving the two connecting columns 16 on the two threaded rods 14, the scraper 17 can be driven to move to one side at the bottom of the sedimentation tank 10, and the sludge at the bottom of the sedimentation tank 10 is scraped to the sludge discharge port, and then the sludge is discharged through the sludge suction pump 20, improving the sludge removal efficiency of the sedimentation tank 10, and further improving the use effect of the tap water production sedimentation device.

[0027] Working principle: First, the tap water to be precipitated is fed into the mixing tank 3, and an appropriate amount of flocculant is added, which can prompt the suspended substances in the water to form larger particles. Then, according to the properties of the water, the control valve 6 on the corresponding delivery pipe 5 is opened, so that the acidic reagent or alkaline reagent in the reagent tank 4 enters the mixing tank 3 along the delivery pipe 5. At this time, the drive motor 7 is started to drive the drive rod 8 and multiple stirring blades 9 to rotate, so as to promote the full mixing of the reagent with the water and the flocculant, thereby increasing the efficiency of the combination of impurities and the flocculant in the water through an appropriate amount of acidic or alkaline reagent and forming larger flocs. Then, the valve 12 is opened, and the water flows into the sedimentation tank 10 along the outlet pipe 11. When the tap water has sedimented in the sedimentation tank 10 for a period of time, the tap water is pumped out and enters the next filtration or disinfection link. At this time, it is necessary to clean the sludge at the bottom of the sedimentation tank 10. Then, two positive and negative motors 13 are started. Since the scraper 17 is installed at the bottom of the two connecting columns 16, and the limit sliders 19 installed on both sides of the scraper 17 are movably embedded in the two limit grooves 18, the two connecting columns 16 can move stably on the two threaded rods 14, and the scraper 17 moves to one side at the bottom of the sedimentation tank 10, scraping the sludge at the bottom of the sedimentation tank 10 to the sludge discharge port, and then discharging the sludge through the sludge suction pump 20, improving the sludge removal efficiency of the sedimentation tank 10. Generally speaking, the use effect of the tap water production sedimentation device is improved.
