Description

Technical Field

[0001] This utility model relates to the field of tap water purification, specifically to a tap water dosing device that saves raw materials. Background Technology

[0002] Disinfection is a key step in the sterilization and disinfection process of water treatment plants. Currently, most water treatment plants disinfect by adding chemicals to the water to purify it. Considering the diffusion effect of chemicals in water, most water treatment plants choose to add excessive amounts of chemicals to ensure the purification effect. This not only wastes money, but the residual chemicals can also cause pollution. Therefore, a water dosing device that saves raw materials is needed.

[0003] Chinese patent CN213977022U discloses a dosing device for a waterworks. A metering component is installed inside a storage tank. This component includes a slide rail, a motor, a driven rod, a turntable, a rotating rod, a limiting frame, a limiting groove, a movable rod, a connecting hole, and a dispensing port. A slide rail is fixedly welded to the middle of the bottom of the storage tank. A motor is fixedly installed on one side of the bottom of the storage tank. A driven rod is rotatably connected to the middle of the top of the motor. A turntable is fixedly installed at the top of the driven rod, and a rotating rod is fixedly welded to the edge of the top of the turntable. By turning on the motor, the driven rod at the output end of the motor rotates, thereby driving the turntable to rotate. When the rotating rod at the top of the turntable rotates, it causes the limiting frame to slide, causing the movable rod connected to one side of the limiting frame to slide back and forth inside the slide rail. When the connecting hole on the movable rod communicates with the dispensing port, the medicine can slide into the water, quantitatively adding the medicine to the water and conserving medicine usage.

[0004] The above document also has several areas for improvement: it lacks a treatment device after the medicine purifies the tap water; and the medicine does not diffuse evenly in the tap water. Utility Model Content

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-6 As shown, a water dosing device for saving raw materials includes a dosing pipe 1, an inlet pipe 5, and a water tank 6. The dosing pipe 1 includes a rotary head 2, a one-way valve 3, and a dosing inlet pipe 4. The inlet pipe 5 is installed on the side of the water tank 6. The dosing pipe 1 is a curved pipe with two ends. One end is inserted vertically into the inlet pipe 5, and the other end is parallel to the inlet pipe 5 with its opening opposite to the water flow direction. The rotary head 2 is set at one end of the dosing pipe 1 and is located in the inlet pipe 5. The one-way valve 3 is installed in the dosing pipe 1 and is close to the rotary head 2. The dosing inlet pipe 4 is inserted vertically into the inlet pipe 5 and is rotatably connected to the rotary head 2.

[0026] The device allows tap water to enter the water tank 6 through the inlet pipe 5. By installing the dosing pipe 1 in the inlet pipe 5 against the direction of water flow, the medicine is evenly diffused under the impact of the water flow. The rotor 2 rotates under the impact of the water flow, causing the tap water to form a vortex in the inlet pipe 5, further diffusing the medicine. The one-way valve 3 ensures that tap water will not enter the dosing pipe 1 after the medicine is added. The inlet pipe 4 is used to control the dosage of the medicine, saving raw materials and avoiding waste.

[0027] See Figures 1-3As shown, the rotor 2 includes fan blades 21 and annular grooves 22. The annular grooves 22 are arranged in a ring on the side of the rotor 2, and the fan blades 21 are also arranged in a ring on the side of the rotor 2, while the fan blades 21 are located behind the annular grooves 22.

[0028] The fan blade 21 is a curved blade. After being impacted by the water flow, it drives the rotor 2 to rotate. The annular groove 22 is used to connect the valve port of the one-way valve 3 to the water inlet pipe 5. It is set on the side of the rotor 2 to effectively reduce the impact of the water flow and prevent the one-way valve 3 from being crushed by the water flow and unable to add medicine.

[0029] See Figure 4 As shown, the one-way valve 3 is characterized by comprising a telescopic rod 32, a spring 33, a top ball 34, and a fixed platform 31. The fixed platform 31 is installed inside the dosing pipe 1, the telescopic rod 32 is installed on the fixed platform 31, the top end of the telescopic rod 32 is connected to the top ball 34, the outer side of the telescopic rod 32 is surrounded by the spring 33, and the top ball 34 is installed on the top of the one-way valve 3.

[0030] The fixed platform 31 is used to install the entire one-way valve 3, and the telescopic rod 32 is used to prevent the spring 33 from falling off the fixed platform 31. When the medicine enters the dosing pipe 1, under the pressure of the medicine, the top ball 34 is pushed away from the one-way valve 3, the spring 33 is stretched, the telescopic rod 32 is extended, and the medicine is discharged outward from the one-way valve 3. After the medicine is added, the spring 33 resets and re-attaches the top ball 34 to the one-way valve 3 to ensure that the one-way valve 3 is closed.

[0031] See Figures 1-3 As shown, the inlet tube 4 includes a ball valve 41, a funnel 42, and an annular interface 43. The ball valve 41 is installed inside the inlet tube 4, the funnel 42 is installed at the top of the inlet tube 4, and the annular interface 43 is located at the connection between the inlet tube 4 and the rotating head 2.

[0032] The funnel 42 facilitates the addition of medicine, the ball valve 41 controls the flow rate of medicine, and the annular interface 43 enables the rotor 2 to rotate.

[0033] See Figures 1-3 As shown, the ball valve 41 includes a baffle 411, a first rotating shaft 412, and a handle 413. The baffle 411 is installed on the ball valve 41 and is located inside the drug inlet tube 4. The first rotating shaft 412 passes through the tube wall of the drug inlet tube 4, with one end connected to the baffle 411 and the other end connected to the handle 413. The handle 413 is fixedly connected to the first rotating shaft 412 and is located on the outer wall of the drug inlet tube 4.

[0034] The handle 413 is used to drive the first rotating shaft 412 to rotate, thereby controlling the rotation of the baffle 411. When the surface of the baffle 411 is parallel to the ground, the ball valve 41 is completely closed. When the surface of the baffle 411 is perpendicular to the ground, the ball valve 41 is completely open, and the medicine obtains the maximum flow rate.

[0035] See Figures 1-5 As shown, the water tank 6 includes a rotating wheel 61 and a filter screen 62. The rotating wheel 61 is installed in the water tank 6 and is rotatably connected to the tank wall of the water tank 6. The filter screen 62 is installed in the water tank 6 and is located below the rotating wheel 61.

[0036] The rotor 61 stirs the medicine in the tap water evenly to achieve a further disinfection effect. The filter screen 62 is used to block the medicine and impurities in the water, so that the tap water under the filter screen 62 is a clean water source after disinfection.

[0037] See Figures 1-5 As shown, the rotor 61 includes a second rotating shaft 611 and blades 612. The second rotating shaft 611 is rotatably connected to the wall of the water tank 6, and the blades 612 are arranged in a ring on the rotor 61.

[0038] The second rotating shaft 611 is powered by an external power supply, which drives the rotating wheel 61 to rotate. The blade 612 stirs the tap water in the water tank 6 when the rotating wheel 61 rotates, so as to spread the medicine evenly.

[0039] See Figures 5-6 As shown, the filter screen 62 includes a frame 621 and a hook 622. The frame 621 surrounds the outside of the filter screen 62, and the hook 622 is mounted on the frame 621 and fits into the wall of the water tank 6.

[0040] The frame 621 is used to fix the filter screen 62, and the hook 622 allows the filter screen 62 to be quickly removed from the water tank 6 for maintenance and replacement, so as to ensure the filtration effect.

[0041] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
