Description

Technical Field

[0001] This utility model relates to the field of capillary network technology, and in particular to a novel anti-clogging capillary network. Background Technology

[0002] Current capillary networks typically use PPR (polypropylene random copolymer) pipes as the main component material. Due to their excellent heat resistance, chemical stability, weldability, and environmental friendliness, they are widely used in underfloor heating systems. Especially in the field of underfloor heating, capillary networks, with their dense and uniformly laid structure, can achieve efficient, energy-saving, and comfortable radiant heating, making them one of the important heating methods in modern green buildings.

[0003] However, as a typical concealed engineering project, underfloor heating capillary networks are usually buried in the ground leveling layer or inside the wall structure, making them difficult to replace and maintain after installation. Therefore, the safety and durability of the system are particularly important. However, in actual operation, the circulating water in heating systems often suffers from poor water quality, containing high levels of calcium and magnesium ions, suspended solids, silt, and microorganisms, which easily form scale deposits on the inner walls of the pipes, severely affecting the normal operation of the system.

The impurities are then discharged outside the system through a discharge pipe. This design achieves automatic collection, crushing, and discharge of impurities, avoiding secondary clogging caused by impurity accumulation, and improving the system's self-cleaning ability and environmental performance.

[0027] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please refer to Figures 1 to 4, an embodiment of the present utility model provides a novel anti-blocking capillary network, including a water inlet pipe 101, which serves as the inlet structure of the entire system. One side of the water inlet pipe 101 is provided with a water inlet 102 for introducing a cooling medium (such as cold water or refrigerant). The end of the water inlet pipe 101 far from the water inlet 102 is fixedly connected to a filter box 103. The end of the filter box 103 far from the water inlet pipe 101 is fixedly connected to a main water pipe 104. A number of capillary pipes 105 are fixedly connected to the side wall of the main water pipe 104. The capillary pipes 105 are made of corrosion-resistant materials, such as polypropylene random copolymer (PP-R), which has good thermal stability and flexibility and is widely used in ground cooling systems.

[0029] Inside the filter box 103, there are a first filter plate 201 and a second filter plate 202. The first filter plate 201 is fixedly connected to one side of the inner wall of the filter box 103 close to the water inlet pipe 101, and its filter holes are larger for intercepting larger impurity particles. The second filter plate 202 is slidably connected to one end of the inner wall of the filter box 103 close to the main water pipe 104, and its filter holes are smaller than those of the first filter plate 201 for further filtering finer suspended matters to ensure that the liquid cleanliness entering the capillary pipes 105 meets the standard.

[0030] To achieve the linkage control between the two filter plates, a limiting rod 205 is fixedly connected to the inner wall of the filter box 103. A fixing block 203 is fixedly connected to the upper side of the first filter plate 201. The end of the limiting rod 205 far from the main water pipe 104 is fixedly connected to the side wall of the fixing block 203. A first slider 204 is fixedly connected to the upper side of the second filter plate 202. The inner wall of the first slider 204 is slidably connected to the outer wall of the limiting rod 205, enabling the second filter plate 202 to slide axially along the limiting rod 205. A first spring 206 is jointly connected between the fixing block 203 and the first slider 204. The spring is sleeved outside the limiting rod 205 to provide a reset elastic force for the second filter plate 202.

[0031] To prevent impurities from continuing to flow into the main water pipe 104 when the filtration fails, a sliding door 301 is slidably connected to the side of the water inlet pipe 101 close to the first filter plate 201 for closing the first filter plate 201. A second slider 302 is fixedly connected to the upper side of the sliding door 301. A first rotating shaft 303 is rotatably connected to the upper side of the second slider 302. A linkage rod 304 is fixedly connected to the side wall of the first rotating shaft 303. The other end of the linkage rod 304 is fixedly connected to a second rotating shaft 305. The lower end of the second rotating shaft 305 is fixedly connected to the upper side of the first slider 204, thus forming a complete mechanical linkage mechanism.

[0032] When the second filter plate 202 slides due to blockage caused by water pressure, it will drive the first slider 204 to move synchronously, which in turn will drive the sliding door 301 to close through the linkage rod 304, blocking the water flow into the filter box 103 and preventing impurities from further entering the main water pipe 104 and capillary pipe 105.

[0033] Furthermore, a baffle 401 is fixedly connected to the upper side of the second filter plate 202. A vibrating block 402 abuts against the upper part of the baffle 401. A second spring 403 is fixedly connected to the side of the vibrating block 402 away from the baffle 401, and the other end of the second spring 403 is fixedly connected to the upper side of the inner wall of the filter box 103. When the second filter plate 202 is pushed and slid, the baffle 401 moves accordingly, releasing the pressure on the vibrating block 402. This causes the second spring 403 to push the vibrating block 402 downward to strike the surface of the second filter plate 202, generating vibration and shaking off the impurities attached to the filter plate, thus achieving automatic unblocking.

[0034] Once the second filter plate 202 is cleared and the blockage is removed, the water pressure drops. At this time, the first spring 206 begins to release its elasticity, pushing the first slider 204 and the second filter plate 202 to reset. Simultaneously, the linkage mechanism drives the sliding door 301 to reopen, restoring normal water flow.

[0035] Please refer to Figures 1 to 4 A collection box 501 is fixedly connected to the lower side of the filter box 103 for collecting impurity particles intercepted by the second filter plate 202. A discharge pipe 502 is fixedly connected to the side wall of the collection box 501 for discharging the crushed impurities outside the system for subsequent cleaning or recycling.

[0036] In order to achieve directional collection of impurities that fall off due to vibration after clogging, a sliding plate 503 is slidably connected to the upper side of the collection box 501. One end of the sliding plate 503 is fixedly connected to the side wall of the second filter plate 202, and the other end is slidably embedded in the groove 504 opened on the collection box 501. The inner wall of the groove 504 slides and cooperates with the outer wall of the sliding plate 503 to ensure its guiding and sealing during movement.

[0037] When the second filter plate 202 slides due to blockage, it simultaneously drives the sliding plate 503 to move into the collection box 501, thereby opening the channel and allowing the impurities shaken off by the vibrating block 402 to fall smoothly into the collection box 501 for centralized collection. At this time, due to the displacement of the sliding plate 503, the crushing mechanism linked to it is triggered to work.

[0038] Specifically, a rotating rod 601 is rotatably connected to the bottom wall of the collection box 501. The rotating rod 601 passes through the side wall of the collection box 501 and can rotate freely. Several cutting rollers 602 are fixedly connected to the outer wall of the rotating rod 601 to crush the impurities falling into the collection box 501, preventing large particles of impurities from accumulating and causing blockages or affecting subsequent discharge efficiency.

[0039] A gear 604 is fixedly connected to one end of the rotating rod 601 near the sliding plate 503, and a toothed plate 603 is fixedly connected to the side of the sliding plate 503 near the gear 604. The teeth on the toothed plate 603 mesh with the teeth of the gear 604. Therefore, when the sliding plate 503 slides with the second filter plate 202, the toothed plate 603 moves accordingly, driving the gear 604 to rotate, which in turn drives the rotating rod 601 and its cutting roller 602 to rotate synchronously, thereby achieving efficient crushing of impurities falling into the collection box 501.

[0040] The crushed impurities are discharged into the collection box 501 through the discharge pipe 502, facilitating regular cleaning or connection to an external sewage system. This structure not only improves the efficiency of impurity treatment but also effectively avoids the risk of secondary blockage caused by impurity accumulation.

[0041] In addition, after the filtration and impurity removal operations are completed, as the second filter plate 202 is reset under the action of the first spring 206, the sliding plate 503 is also reset synchronously, closing the channel into the collection box 501 and preparing for the next filtration operation.

[0042] In summary, the working principle of this novel anti-clogging capillary network according to this utility model embodiment is as follows: Cooling medium (such as cold water or refrigerant) enters the inlet pipe 101 through the inlet 102, and then flows into the filter box 103 connected to its end. Before entering the main water pipe 104, the liquid needs to undergo two stages of filtration: the first stage is a fixed first filter plate 201, which is used to intercept larger particulate impurities; the second stage is a sliding second filter plate 202, whose filter holes are smaller, which can further remove suspended solids and tiny particles, ensuring the cleanliness of the water entering the main water pipe 104 and multiple capillary pipes 105.

[0043] When the second filter plate 202 becomes clogged due to impurities, the water pressure gradually increases, pushing the second filter plate 202 to slide inward along the direction of the limiting rod 205. The upper side of the second filter plate 202 is slidably engaged with the limiting rod 205 via the first slider 204, and connected to the fixing block 203 on the first filter plate 201 via the first spring 206, which serves as a reset function. As the second filter plate 202 slides, it drives the sliding plate 503 connected to it to move synchronously. One end of the sliding plate 503 is connected to the second filter plate 202, and the other end is embedded in the groove 504 on the collection box 501. During the sliding process, the channel is opened, allowing the shaken impurities to fall into the collection box 501 below for centralized collection.

[0044] Simultaneously, the sliding of the second filter plate 202 triggers the mechanical linkage mechanism. The toothed plate 603 on the sliding plate 503 meshes with the gear 604, driving the rotating rod 601 to rotate, which in turn drives the cutting roller 602 on it to rotate at high speed, crushing the impurities that fall into the collection box 501. The crushed impurities are finally discharged from the collection box 501 through the discharge pipe 502, achieving automatic cleaning. In addition, during the sliding of the second filter plate 202, the baffle 401 fixed on it moves synchronously, releasing the pressure on the vibrating block 402 above. At this time, the compressed second spring 403 pushes the vibrating block 402 downward to strike the surface of the second filter plate 202, causing it to vibrate, thereby shaking off the impurities attached to the filter screen and completing the automatic unblocking operation.

[0045] After the blockage is completed, the water pressure decreases, and the first spring 206 releases its elasticity, pushing the first slider 204 and the second filter plate 202 to reset. At the same time, the linkage mechanism drives the sliding door 301 to reopen, restoring the normal water flow path. The sliding plate 503 also resets, closing the inlet of the collection box 501 and preparing for the next filtration operation.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
