Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a tap water raw water impurity removal and filtration device. Background Technology

[0002] Raw water refers to water sources in nature, including rivers, lakes, and groundwater. These water sources are untreated and contain a large number of impurities and microorganisms. Tap water refers to water that meets relevant standards and is used for daily life and production after being purified and disinfected by a water treatment plant. Water plants draw water from rivers, lakes, groundwater, and surface water through pumping stations, and remove most of the impurities and microorganisms from the raw water, making tap water safer and more hygienic.

[0003] Currently, most tap water treatment methods involve using activated carbon to filter out organic matter, impurities, and other substances from raw water. However, activated carbon has limited removal capabilities and is not very effective at removing some recalcitrant substances and microorganisms, resulting in incomplete filtration in practice. Furthermore, since some filtration devices are installed directly in designated areas, large-scale maintenance requires disassembling and transporting the entire device, increasing the difficulty and cost of repair and maintenance.

[0004] In summary, current tap water raw water purification and filtration devices have gradually revealed the following shortcomings during use:

[0005] 1) Direct filtration through activated carbon medium results in incomplete filtration;

[0006] 2) Directly installing the impurity removal and filtration device in a designated location increases the difficulty and cost of maintenance and repair. Utility Model Content

[0036] like Figures 1 to 5 As shown in the figure, this embodiment provides a tap water raw water impurity removal and filtration device. This tap water raw water impurity removal and filtration device includes a base plate 1, on which an activated carbon filter tank 2, a sand and gravel filter media tank 3, and a sterilization tank 4 are sequentially arranged. The inlet of the activated carbon filter tank 2 is connected to a water pumping pipe 5, and a water pump 6 is installed on the water pumping pipe 5. A first water supply pipe 7 is provided between the activated carbon filter tank 2 and the sand and gravel filter media tank 3. One end of the first water supply pipe 7 is connected to the outlet of the activated carbon filter tank 2. The other end of a water supply pipe 7 is connected to the inlet of the sand and gravel filter tank 3, and a first water pump 8 is installed on the first water supply pipe 7.

One end of the second water supply pipe 9 is connected to the outlet of the sand and gravel filter tank 3, and the other end of the second water supply pipe 9 is connected to the inlet of the sterilization tank 4. A second water pump 10 is installed on the second water supply pipe 9. A fixing plate is installed at the bottom of the water pump 6 to keep the water pump 6 stable.

[0037] The sterilization tank 4 is equipped with a rotating shaft 11 driven by a drive device. The rotating shaft 11 is equipped with a sterilization component and a stirring component.

[0038] A first pump body mounting bracket 12 is fixedly installed between the activated carbon filter tank 2 and the sand and gravel filter tank 3. A first water pump 8 is installed on the first pump body mounting bracket 12. One end of the first water supply pipe 7 is connected to the bottom of the activated carbon filter tank 2, and the other end of the first water supply pipe 7 is connected to the top of the sand and gravel filter tank 3.

[0039] A second pump mounting bracket 13 is fixedly installed between the sand and gravel filter tank 3 and the sterilization tank 4.

One end of the second water supply pipe 9 is connected to the bottom of the sand and gravel filter tank 3, and the other end of the second water supply pipe 9 is connected to the top of the sterilization tank 4.

[0040] The bottom of the activated carbon filter tank 2 is connected to the first drain pipe 14, the bottom of the sand and gravel filter tank 3 is connected to the second drain pipe 15, and the bottom of the sterilization tank 4 is connected to the third drain pipe 16. Solenoid valves 17 are installed on the first drain pipe 14, the second drain pipe 15, and the third drain pipe 16. The solenoid valves 17 are used to control the opening and closing of the first drain pipe 14, the second drain pipe 15, and the third drain pipe 16 to prevent raw water from accumulating in the activated carbon filter tank 2 and the sand and gravel filter tank 3.

[0041] The drive unit includes a drive motor 18 fixedly installed on the top of the sterilization tank 4, a rotating shaft 11 vertically rotatably installed inside the sterilization tank 4, and the output shaft of the drive motor 18 extends into the sterilization tank 4 and is fixedly connected to the top of the rotating shaft 11.

[0042] The sterilization components are provided in two sets, which are respectively set at the top and bottom of the rotating shaft 11, and the stirring component is located between the two sets of sterilization components.

[0043] The sterilization component includes a hinge seat 19 fixedly installed on the rotating shaft 11. The hinge seat 19 has several hinges arranged circumferentially along the rotating shaft 11. A connecting block 20 is hingedly installed on the hinge seat 19. An ultraviolet lamp tube 21 is installed at the end of the connecting block 20 away from the hinge seat 19.

[0044] The end of the connecting block 20 away from the hinge seat 19 is also fixedly connected to a mounting ring 22. The inner side of the mounting ring 22 is provided with an internal thread. The ultraviolet lamp tube 21 is covered with a transparent lamp cover 23. One end of the transparent lamp cover 23 is provided with an external thread that matches the mounting ring 22. The transparent lamp cover 23 is sealed and fixedly connected to the mounting ring 22. The transparent lamp cover 23 can prevent the ultraviolet lamp tube 21 from directly contacting the raw water, thereby protecting the ultraviolet lamp tube 21.

[0045] The stirring assembly includes a stirring paddle 24. Several stirring paddles 24 are arranged evenly along the circumference of the rotating shaft 11, and one end of the stirring paddle 24 is fixedly connected to the rotating shaft 11. The stirring paddle 24 can rotate the raw water, making the irradiation of the ultraviolet lamp tube 21 more uniform.

[0046] A control panel 25 is fixedly installed on the base plate 1;

[0047] Alternatively, a top plate 26 is provided above the bottom plate 1, and a plurality of connecting rods 27 are provided between the top plate 26 and the bottom plate 1, with the two ends of the connecting rods 27 being fixedly connected to the bottom plate 1 and the top plate 26 respectively.

[0048] Locking casters 28 are installed at the bottom corners of the base plate 1.

[0049] In use, the water pump 6 is started to draw raw water through the water pipe 5 and deliver it to the activated carbon filter tank 2. The activated carbon medium in the activated carbon filter tank 2 can remove impurities such as organic matter, chlorine, odor, and color from the water, and can also adsorb some heavy metal ions and radioactive substances. At the same time, the first water pump 8 is started to deliver the pre-filtered water to the sand and gravel filter tank 3 through the first water pipe 7. The sand and gravel filter media in the sand and gravel filter tank 3 can filter out larger suspended solids and some large molecular organic matter. Similarly, the second water pump 10 is started to deliver the secondary filtered water to the sterilization tank 4 through the second water pipe 9. The ultraviolet lamp 21 inside the sterilization tank 4 performs a second sterilization operation. In this way, the overall impurity removal and filtration operation can be completed. By using the three together, the pollutant removal effect of each can be fully utilized, and the stability and quality of water quality can be improved while ensuring water safety.

[0050] When water enters the sterilization tank 4, the drive motor 18 can be started to drive the rotating shaft 11 to rotate, which in turn drives the stirring paddle 24 and the hinge seat 19 to rotate. During the rotation of the stirring paddle 24, the water source can be rotated, improving the uniformity of water sterilization. At the same time, during the rotation of the hinge seat 19, the rotational force of its hinge seat 19 can cause the connecting block 20 to slowly rotate the ultraviolet lamp tube 21, that is, the ultraviolet lamp tube 21 slowly changes from being horizontal with the rotating shaft 11 to being vertical with the rotating shaft 11, so as to increase the irradiation range of the ultraviolet lamp tube 21.

[0051] When maintenance is required on the device, the thrust can be transmitted to the top plate 26 and the bottom plate 1 by pushing the connecting rod 27, and finally the position can be adjusted by locking the caster wheel 28, thereby improving the flexibility of the device and facilitating its maintenance.

[0052] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
