Description

Technical Field

[0001] This invention relates to the field of water supply equipment technology, specifically to an intelligent negative pressure-free water supply device with water purification function. Background Technology

[0002] Negative pressure-free water supply equipment, as an energy-saving and efficient secondary water supply solution, is widely used in urban high-rise buildings, residential communities, industrial parks, and other scenarios. Its core function is to balance the pressure of the pipeline network through a flow stabilizing tank, avoiding negative pressure impacts on the municipal water supply system while ensuring the stability and continuity of the water supply. With increasing demands for water quality, water purification during the supply process has become a critical requirement. Sediment, impurities, and colloidal particles in the water can not only clog water supply equipment pipelines and wear down pumps, affecting equipment lifespan, but also lead to water quality deterioration and harm to user health.

[0003] Existing equipment filtration mechanisms are mostly single-stage filtration systems with fixed filter pore sizes. This makes it impossible to classify and intercept impurities of different particle sizes, allowing fine impurities to easily penetrate the filter layer. This affects the operational safety of subsequent water supply equipment and the purity of the water. Different water sources have significant differences in impurity content and particle size distribution. For example, there is more silt during the rainy season and finer impurity particles during the dry season. The filtration intensity of existing filtration mechanisms is fixed and cannot be adjusted according to changes in water quality. This can easily lead to problems such as over-filtration causing increased energy consumption or under-filtration causing impurity residue. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent negative pressure-free water supply device with water purification function, thereby solving the problems existing in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A smart negative pressure-free water supply device with water purification function includes a base plate, on which a flow stabilizing tank is fixedly installed, and connecting pipes are fixedly connected to both sides of the top of the flow stabilizing tank, while a filter mechanism is installed on the connecting pipes.

[0007] The filtration mechanism includes a docking cylinder, which is fixed to the top of the connecting pipe;

[0008] The coarse filter disc slides in the groove of the docking cylinder through sliding plates fixed on both sides, and two flat spheres are fixed on both sides.

[0009] The limiting post is fixedly connected to the sliding groove inside the docking cylinder and its surface is slidably connected to the sliding plate.

[0010] The spring is fixed to the surface of the sliding plate;

[0011] The drive shaft is rotatably connected to the middle of the coarse filter disc and has movable plates fixed on both sides. Two flat spheres are fixed to the other end of the movable plates.

[0012] The rotation of the drive shaft causes the moving plate to carry the first flat sphere and the second flat sphere on both sides of the coarse filter disc to alternate, thus making the coarse filter disc shake up and down.

[0013] As a further embodiment of the present invention: the filtration mechanism further includes a fine filter disc, which is fixed to the docking cylinder and has a scraper that slides inside the fixed block.

[0014] The connecting frame is fixed to both sides of the middle of the fine filter disc and has a collection box slidably connected inside;

[0015] The connecting rod is fixed to the middle of the collection box;

[0016] The protective cover is bolted to the middle of the connecting cylinder;

[0017] Activated carbon plates are fixed inside the docking cylinder and are used to remove odors from water.

[0018] As a further embodiment of the present invention: a water inlet pipe is fixedly connected to the top of the docking cylinder, an impeller is rotatably connected inside the water inlet pipe, and a transmission cylinder is fixedly connected to the bottom of the impeller. At the same time, the transmission cylinder is rotatably connected to the middle of the coarse filter disc and the fine filter disc. The diameter of the fine filter disc is larger than the diameter of the coarse filter disc, and the diameter of the coarse filter disc is the same as the inner diameter of the water inlet pipe.

[0019] The diameter of the fine filter disc is the same as the inner diameter of the docking cylinder.

[0020] As a further embodiment of the present invention: the transmission shaft is rotatably connected to the middle part of the transmission cylinder;

[0021] The movable plate is slidably connected to a groove opened on one side of the transmission cylinder.

[0022] As a further aspect of the present invention: the fixing block is fixed to the surface of the transmission cylinder and is used to follow the rotation of the transmission cylinder.

[0023] As a further aspect of the present invention: an adjustment mechanism is provided at the top of the water inlet pipe to adjust the distance between the second spherical body and the first spherical body.

[0024] As a further aspect of the present invention: the adjustment mechanism includes a limiting plate, which is fixedly connected to the top of the water inlet pipe;

[0025] The positioning block is fixed to the middle of the limiting plate and has a sliding connection to the moving block inside;

[0026] A threaded rod is rotatably connected to one side of the positioning block;

[0027] The connecting disc is fixed to both sides of the moving block and rotatably connected to the drive shaft.

[0028] As a further aspect of the present invention: the movable block is threadedly connected to the surface of the threaded rod, and a knob is fixedly connected to the top of the threaded rod.

[0029] As a further aspect of the present invention: a transmission pipe is connected to one side of the water inlet pipe, and a connecting pipe is connected to the other end of the transmission pipe. The other end of the connecting pipe is fixedly connected to a connecting flange that mates with the flange of the water supply pipe.

[0030] As a further aspect of the present invention: a bracket is fixedly connected to the substrate, and a vertical multistage pump is fixedly connected to the bracket; at the same time, one end of the vertical multistage pump is fixedly connected to the inlet integrated main pipe through an outlet check valve.

[0031] The other end of the vertical multistage pump is fixedly connected to the main outlet pipe via an inlet valve, and a pressure stabilizer is fixedly installed on the main outlet pipe.

[0032] A diversion pipe is fixedly connected to the middle of one side of the integrated water inlet pipe, and the other end of the diversion pipe is fixedly connected to the bottom of the flow stabilizing tank. A control box is fixedly installed on one side of the bracket.

[0033] The beneficial effects of this invention are:

[0034] (1) In this invention, the coarse filter disc achieves automatic up-and-down shaking through the transmission shaft, the flat spheres, and the spring reset structure, which prevents impurities from adhering to the surface of the filter holes. The scraper on the surface of the fine filter disc rotates synchronously with the transmission cylinder. Its structure, which is adapted to the inclined surface of the filter screen, and the design of the elastic hard composite material ensure that impurities are completely scraped off and fall into the collection box. There is no need to stop the machine for manual cleaning, which reduces the maintenance frequency.

[0035] (2) In this invention, the spacing between the flat spheres can be adjusted by the adjustment mechanism, thereby changing the shaking amplitude of the coarse filter disc and realizing flexible adjustment of the filtration intensity to adapt to different water qualities, such as high sand content in the rainy season and low impurities in daily life. At the same time, the flat spheres adopt an arc surface design to avoid cross-interference, the scraper and the filter screen fit well, and the limiting column and spring structure ensure the stability of shaking. The detachable design of the protective cover and the collection box makes it easy to clean impurities, while protecting the internal components and extending the service life of the equipment.

[0036] (3) In this invention, two sets of coarse filter discs with progressively smaller pore sizes from top to bottom are used in combination with fine filter discs to achieve graded filtration of coarse and fine filters. This allows for targeted separation of impurities of different particle sizes. The conical filter screen design allows impurities to slide naturally down the inclined surface, reducing accumulation and improving filtration efficiency. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Example 1

[0052] Please see Figures 1-11 As shown, the present invention is an intelligent negative pressure-free water supply device with water purification function, including a base plate 1, a flow stabilizing tank 2 fixedly installed on the base plate 1, and connecting pipes 3 fixedly connected to both sides of the top of the flow stabilizing tank 2, and a filter mechanism 4 installed on the connecting pipes 3.

[0053] The filter mechanism 4 includes a docking cylinder 400, which is fixed to the top of the connecting pipe 3;

[0054] The coarse filter disc 406 slides in the groove of the docking cylinder 400 through the sliding plates 407 fixed on both sides, and flat spherical bodies 418 are fixed on both sides.

[0055] The limiting post 409 is fixedly connected to the sliding groove inside the docking cylinder 400 and its surface is slidably connected to the sliding plate 407.

[0056] Spring 408 is fixedly attached to the surface of sliding plate 407;

[0057] The drive shaft 404 is rotatably connected to the middle of the coarse filter disc 406 and has movable plates 416 fixed on both sides. The other end of the movable plate 416 is fixed to a flat spherical body 418.

[0058] The drive shaft 404 rotates, causing the moving plate 416 to carry the first flat sphere 417 to intersect with the second flat sphere 418 on both sides of the coarse filter disk 406, thus realizing the up-and-down shaking of the coarse filter disk 406.

[0059] It should be noted that the coarse filter plate 406 is provided with filter holes so that water can pass through the coarse filter plate 406 in sequence for filtration.

[0060] Two sets of coarse filter disc 406, sliding plate 407, spring 408, and limiting post 409 are provided. The filter holes of the two sets of coarse filter discs 406 are progressively smaller from top to bottom. The spring 408 is sleeved on the outside of the limiting post 409 and is set in the groove of the docking cylinder 400.

[0061] The coarse filter disc 406 is tapered, which makes it easier for impurities on the surface of the coarse filter disc 406 to slide off the inclined surface.

[0062] Both the first oblate spheroid 417 and the second oblate spheroid 418 are designed with curved surfaces to avoid interference when they intersect.

[0063] Preferably, in this invention, the filtration mechanism 4 further includes a fine filter disc 410, which is fixed to the docking cylinder 400 and has a scraper 415 that slides inside the fixing block 414.

[0064] The connecting frame 411 is fixed to both sides of the middle part of the fine filter disc 410 and has a collection box 412 slidably connected inside it.

[0065] The connecting rod 413 is fixed to the middle of the collection box 412;

[0066] The protective cover 401 is bolted to the middle of the connecting cylinder 400;

[0067] Activated carbon plate 405 is fixed inside docking cylinder 400 and is used to remove odors from water.

[0068] It should be noted that the scraper 415 is a two-section design. One section of the scraper 415, which is located inside the fixing block 414, is made of elastic rubber material, while the side of the scraper 415 that is in contact with the fine filter disc 410 is made of hard material.

[0069] The bottom of scraper block 415 is adapted to the inclined surface of fine filter disc 410 to prevent scraper block 415 from scraping material incompletely;

[0070] The surface of the fine filter disc 410 is provided with filter holes that are smaller than those on the surface of the coarse filter disc 406. The fine filter disc 410 is tapered to facilitate the sliding of impurities from the surface of the fine filter disc 410 down the slope.

[0071] Both the bottom of the connecting frame 411 and the collection box 412 are provided with filter holes smaller than those of the fine filter disc 410. The connecting rod 413 is designed to prevent the scraper 415 from being completely trapped in the collection box 412 during movement, thus avoiding interference.

[0072] The protective cover 401 and the collection box 412 are located on the same side.

[0073] Preferably, in this invention, a water inlet pipe 5 is fixedly connected to the top of the docking cylinder 400, an impeller 402 is rotatably connected inside the water inlet pipe 5, and a transmission cylinder 403 is fixedly connected to the bottom of the impeller 402. At the same time, the transmission cylinder 403 is rotatably connected to the middle of the coarse filter disc 406 and the fine filter disc 410. The diameter of the fine filter disc 410 is larger than the diameter of the coarse filter disc 406, and the diameter of the coarse filter disc 406 is the same as the inner diameter of the water inlet pipe 5.

[0074] The diameter of the fine filter disc 410 is the same as the inner diameter of the docking cylinder 400.

[0075] It should be noted that the blades on the surface of impeller 402 are set at a 30-degree angle to facilitate the rotation caused by water flow impact;

[0076] The diameter of the coarse filter plate 406 is the same as the inner diameter of the water inlet pipe 5, so that the water in the water inlet pipe 5 can be initially filtered by the coarse filter plate 406. The diameter of the coarse filter plate 406 is smaller than the diameter of the fine filter plate 410, so that the impurities on the surface of the coarse filter plate 406 can fall to the surface of the fine filter plate 410.

[0077] Preferably, in this invention, the transmission shaft 404 is rotatably connected to the middle part of the transmission cylinder 403;

[0078] The movable plate 416 is slidably connected to a groove opened on one side of the transmission cylinder 403.

[0079] It should be noted that the drive shaft 404 is slidably and rotatably connected to the inside of the drive cylinder 403.

[0080] Preferably, in this invention, the fixing block 414 is fixed to the surface of the transmission cylinder 403 and is used to rotate with the transmission cylinder 403.

[0081] Preferably, in this invention, a transmission pipe 7 is connected to one side of the water inlet pipe 5, and a connecting pipe 8 is connected to the other end of the transmission pipe 7. A connecting flange 10 that is connected to the flange of the water supply pipe is fixed to the other end of the connecting pipe 8.

[0082] It should be noted that the section connecting the transmission pipe 7 and the water inlet pipe 5 is inclined to facilitate the impact of the water flow in the transmission pipe 7 on the impeller 402, thereby enabling the impeller 402 to rotate.

[0083] The surface of the connecting flange 10 is provided with multiple mating holes to facilitate mating with the flange of the water supply pipeline, and is locked with bolts.

[0084] During the implementation process, water is introduced into the connecting pipe 8 through the connecting flange 10. After the water flows into the transmission pipe 7, it enters the docking cylinder 400 through the inlet pipe 5 and passes through two sets of coarse filter discs 406, sliding plates 407 and activated carbon plates 405 in sequence for filtration and odor removal. Then, it flows into the stabilizing tank 2 through the connecting pipe 3.

[0085] Water flows through the transmission pipe 7 and impacts the side of the impeller 402. The impeller 402 drives the transmission cylinder 403 to rotate. The transmission cylinder 403, along with the moving plate 416, the transmission shaft 404, and the first flat sphere 417, rotates along the middle of the coarse filter plate 406, the fine filter plate 410, the adjusting mechanism 6, and the connecting plate 63. The first flat sphere 417 rotates with the transmission cylinder 403 and rotates and intersects with the second flat sphere 418 on both sides of the two sets of coarse filter plates 406. When the first flat sphere 417 and the second flat sphere 418 intersect, the second flat sphere 418, along with the coarse filter plate 406 and the sliding plate 407, moves upward along the groove in the docking cylinder 400 and pushes and squeezes the spring 408. At the same time, it moves downward quickly through the counter-thrust of the spring 408, realizing the up and down shaking of the coarse filter plate 406, causing the impurities on the surface of the coarse filter plate 406 to slide off the inclined surface and fall to the side surface of the fine filter plate 410.

[0086] As the transmission cylinder 403 rotates, it also rotates the fixed block 414 and the scraper 415. The scraper 415 rotates and is pressed against the surface of the fine filter disc 410 by the fixed block 414. The scraper 415 rotates and scrapes the surface of the fine filter disc 410, so that the impurities falling from the fine filter disc 410 and the coarse filter disc 406 are pushed by the scraper 415 into the collection box 412. The water inside the collection box 412 flows out through the filter holes, and the impurities remain inside the collection box 412 due to gravity. When the scraper 415 passes through the collection box 412, it is prevented from being completely trapped in the collection box 412 and causing interference due to the obstruction of the connecting rod 413.

[0087] Rotate the bolts of the protective cover 401 to remove the protective cover 401. Removing the protective cover 401 exposes the groove on the surface of the docking cylinder 400. Pull the collection box 412, and the collection box 412, along with the internal impurities, slides out along the connecting frame 411, making it easier to clean the impurities inside the collection box 412.

[0088] Example 2

[0089] Preferably, the top of the water inlet pipe 5 is provided with an adjustment mechanism 6 to adjust the distance between the second spherical body 418 and the first spherical body 417.

[0090] Preferably, in this invention, the adjusting mechanism 6 includes a limiting plate 60, which is fixed to the top of the water inlet pipe 5;

[0091] The positioning block 61 is fixed to the middle of the limiting plate 60 and has a sliding connection to the moving block 62 inside.

[0092] The threaded rod 64 is rotatably connected to one side of the positioning block 61;

[0093] The connecting plate 63 is fixed to both sides of the movable block 62 and rotatably connected to the drive shaft 404.

[0094] Preferably, in this invention, the movable block 62 is threadedly connected to the surface of the threaded rod 64, and a knob 65 is fixedly connected to the top of the threaded rod 64.

[0095] It should be noted that the connection plate 63 is designed to facilitate the rotation of the threaded rod 64;

[0096] The connecting disc 63 is embedded in the surface of the drive shaft 404, allowing the drive shaft 404 to rotate along the middle of the connecting disc 63, and the drive shaft 404 can be pulled by the connecting disc 63.

[0097] Preferably, in this invention, a bracket 16 is fixedly connected to the base plate 1, and a vertical multistage pump 13 is fixedly connected to the bracket 16. At the same time, one end of the vertical multistage pump 13 is fixedly connected to the inlet integrated main pipe 12 through the outlet check valve 18.

[0098] The other end of the vertical multistage pump 13 is fixedly connected to the outlet foundation main pipe 14 through the inlet valve 17, and a pressure stabilizer 19 is fixedly installed on the outlet foundation main pipe 14.

[0099] A diversion pipe 20 is fixedly connected to the middle of one side of the water inlet integrated main pipe 12, and the other end of the diversion pipe 20 is fixedly connected to the bottom of the flow stabilizing tank 2. A control box 15 is fixedly installed on one side of the bracket 16.

[0100] It should be noted that the controller (not shown) is installed inside the control box 15 and is electrically connected to the vertical multistage pump 13, the inlet valve 17, the outlet check valve 18, and the pressure regulator 19, and is controlled by wireless signal transmission.

[0101] During implementation, the water flow in the stabilizing tank 2 is introduced into the inlet integrated main pipe 12 through the diversion pipe 20. The outlet check valve 18 is opened, and the vertical multistage pump 13 is started. The vertical multistage pump 13 pulls the water flow in the inlet integrated main pipe 12 and opens the inlet valve 17 to transmit it to the inside of the outlet foundation main pipe 14. A pressure stabilizer 19 is set up, and the pressure stabilizer 19 stabilizes the water flow inside the outlet foundation main pipe 14 before outputting the water flow.

[0102] When it is necessary to adjust the vibration amplitude of the coarse filter disc 406, turn the knob 65. The knob 65 rotates the threaded rod 64, which causes the moving block 62 to move up or down along the positioning block 61 for adjustment. The moving block 62 moves the connecting plate 63 up or down, and the connecting plate 63 moves the transmission shaft 404 and the moving plate 416 up or down along the middle of the transmission cylinder 403 and the slide groove for fine adjustment. The moving plate 416 moves the first flat sphere 417 up or down for fine adjustment, so that the distance between the first flat sphere 417 and the second flat sphere 418 can be adjusted to adjust the height difference when the arc surfaces of the first flat sphere 417 and the second flat sphere 418 intersect, thereby adjusting the vibration amplitude of the coarse filter disc 406 so that the up and down vibration of the coarse filter disc 406 can be adjusted according to the required amplitude.

[0103] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
