Technical Field
[0001] This utility model relates to the field of pipeline anti-clogging technology, and in particular to an anti-clogging device for hot water delivery pipelines. Background Technology
[0002] The core function of anti-clogging devices for hot water delivery pipelines is to prevent blockages caused by the accumulation of foreign objects, scale, or biological adhesion by intercepting impurities, inhibiting scale formation, and guiding water flow. At the same time, they must be able to withstand the high-temperature environment of hot water and ensure material stability and long-term effectiveness.
[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing anti-clogging devices are typically connected to pipes to filter out scale, silt, and impurities within the pipes. They lack a structure to guide scale, silt, and impurities to the bottom of the filter device, causing scale, silt, and impurities to accumulate on the inside of the filter device over a long period of time, reducing the effective filtration area and thus significantly increasing the resistance of hot water flowing through the filter device.
[0004] Therefore, an anti-clogging device for hot water delivery pipelines is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an anti-clogging device for hot water delivery pipelines. This device solves the problem that existing pipeline anti-clogging systems, which are typically connected to the pipeline and filter out scale, silt, and impurities inside the pipeline, lack a structure to guide these scale, silt, and impurities to the bottom of the filter. This results in scale, silt, and impurities accumulating on the inside of the filter for a long time, reducing the effective filtration area, and thus significantly increasing the resistance of hot water flowing through the filter.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging device for hot water delivery pipelines, comprising a connecting pipe, a filter mechanism snapped into the bottom of the connecting pipe, a drain mechanism welded to the bottom of the filter mechanism, a snap-fit interface at the bottom of the connecting pipe, the filter mechanism comprising a connecting plate, a filter pipe, a filter ring, and a drain hopper, the connecting plate snapping into the bottom surface of the snap-fit interface, the filter pipe welded to the top surface of the connecting plate, the filter ring welded to the right side of the inner side of the filter pipe, a filter non-woven fabric fixedly connected to the inner side of the filter ring, and the drain hopper fixedly connected to the bottom of the inner side, the bottom of the drain hopper penetrating and extending to the outer side of the bottom of the connecting plate.
[0007] Preferably, the sewage discharge mechanism includes a mounting shell, a water filter pipe, a drain pipe, a sewage discharge pipe, and a solenoid one-way valve, wherein the mounting shell is welded to the bottom of the sewage discharge hopper surface.
[0008] Preferably, the filter pipe is welded to the inside of the mounting shell, the top of the filter pipe is aligned with the bottom of the sewage hopper, and the drain pipe is fixedly connected to the bottom of the right side of the mounting shell.
[0009] Preferably, the drain pipe is fixedly connected to the bottom of the mounting housing, and the electromagnetic one-way valve is installed on the bottom surface of the drain pipe and the bottom surface of the drain pipe, respectively.
[0010] Preferably, the surface of the filter pipe is provided with a plurality of drainage holes, and a filter screen is fixedly connected to the inner side of the drainage holes.
[0011] Preferably, the bottom of the connecting pipe has insertion slots on both sides, and the top of the connecting plate has sealing strips on both sides, which engage with the insertion slots.
[0012] Preferably, connecting screw holes are provided on both sides of the connecting pipe and on both sides of the top of the connecting plate, and a fixing screw is threaded into the inner side of the connecting screw hole.
[0013] Preferably, a flow guide cone is welded to the left side of the inner side of the filter ring, and the tip of the flow guide cone faces the left side of the filter tube.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The filter ring and filter non-woven fabric in the filter mechanism of this application form a filter unit, which can specifically intercept impurities such as mud, rust, and fine scale particles in hot water, preventing impurities from entering the subsequent hot water delivery pipe with the water flow. This fundamentally reduces the probability of scaling and blockage on the inner wall of the pipe, and extends the service life of the entire hot water pipe network. The drain hopper adopts a funnel-shaped structure, which can quickly guide the impurities intercepted in the filter tube to the drain mechanism at the bottom, preventing impurities from accumulating in the filter tube and blocking the filter channel. Compared with traditional filter devices without a flow guiding structure, it can reduce the residence time of impurities in the filter chamber and reduce the problem of decreased filtration efficiency caused by impurity agglomeration. The detachable connection method of the connecting plate facilitates the replacement of the filter non-woven fabric and the cleaning of the inner wall of the filter tube without disassembling the entire device, reducing maintenance costs and pipeline downtime. It is especially suitable for scenarios such as hotels and factories that require continuous hot water supply. 2. In this application, the filter pipe in the sewage discharge mechanism is aligned with the sewage discharge hopper, which can receive impurities and some hot water flowing from the filtration mechanism. The water leakage holes on its surface and the filter screen form a secondary filtration unit, which allows clean hot water to flow into the installation shell through the water leakage holes and then return to the main pipe through the drain pipe, while also intercepting residual fine impurities to avoid water waste. Compared with the traditional design of directly discharging sewage and losing heated water, it can save hot water resources. The electromagnetic single-way valve controls the opening and closing of the drain pipe and the sewage discharge pipe respectively, realizing the automatic switching of the filtration and sewage discharge process. During normal filtration, the drain pipe valve is open and the sewage discharge pipe valve is closed to ensure hot water return. When sewage discharge is required, the drain pipe valve is closed and the sewage discharge pipe valve is open, and impurities are quickly discharged with a small amount of residual hot water. The sewage discharge pipe is located at the bottom of the installation shell, and uses gravity to assist the discharge of impurities, avoiding the accumulation and blockage of impurities in the sewage discharge pipe, and ensuring a smooth and efficient sewage discharge process.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-5 The present invention provides the following technical solution: An anti-clogging device for hot water delivery pipelines includes a connecting pipe 1, a filter mechanism 2 snapped onto the bottom of the connecting pipe 1, a drain mechanism 3 welded onto the bottom of the filter mechanism 2, and a snap-fit interface at the bottom of the connecting pipe 1. The filter mechanism 2 includes a connecting plate 21, a filter pipe 22, a filter ring 23, and a drain hopper 24. The connecting plate 21 is snapped onto the bottom surface of the snap-fit interface, the filter pipe 22 is welded onto the top surface of the connecting plate 21, the filter ring 23 is welded onto the right side of the inner side of the filter pipe 22, a filter non-woven fabric is fixedly connected to the inner side of the filter ring 23, and the drain hopper 24 is fixedly connected to the bottom of the inner side, with the bottom of the drain hopper 24 penetrating and extending to the outer side of the bottom of the connecting plate 21.
[0019] In this embodiment: The connecting pipe 1 provides a stable installation foundation for the subsequent filter mechanism 2 and sewage discharge mechanism 3, and can be connected to the hot water pipe to guide hot water to the filter mechanism 2. The snap-fit interface, through its snap-fit engagement with the connecting plate 21, enables quick assembly of the connecting pipe 1 and the filter mechanism 2. The connecting plate 21, through its snap-fit engagement, allows for quick installation and disassembly of the filter mechanism 2, facilitating later maintenance and replacement of the filter components. Furthermore, the close fit with the snap-fit interface reduces the risk of water leakage at the connection point. The filter pipe 22 provides independent filtration space for hot water and impurities, preventing impurities from directly entering with the water flow. The subsequent pipes, with their tubular structure, guide water flow evenly through the filter ring 23, ensuring full utilization of the filtration area and improving filtration efficiency. The non-woven filter cloth inside the filter ring 23 effectively intercepts impurities such as mud, rust, and fine scale particles in the hot water. The high-temperature resistant non-woven fabric material can adapt to the high-temperature environment of the hot water pipes, preventing material deformation or failure. The drain hopper 24, through its funnel-shaped structure, directs the impurities intercepted in the filter tube 22 to the drain mechanism 3 at the bottom, preventing impurities from accumulating and clogging the filter channel in the filter tube 22. It also reduces the adhesion of impurities to the inner wall of the filter tube 22, reducing the difficulty of later cleaning.
[0020] Specifically, such as Figure 3 As shown, the sewage discharge mechanism 3 includes a mounting shell 31, a water filter pipe 32, a drain pipe 33, a sewage discharge pipe 34, and a solenoid one-way valve 35. The mounting shell 31 is welded to the bottom of the surface of the sewage discharge hopper 24.
[0021] Specifically, such as Figure 3 As shown, the filter pipe 32 is welded to the inside of the mounting shell 31, the top of the filter pipe 32 is aligned with the bottom of the sewage hopper 24, and the drain pipe 33 is fixedly connected to the bottom of the right side of the mounting shell 31.
[0022] Specifically, such as Figure 3 As shown, the drain pipe 34 is fixedly connected to the bottom of the mounting housing 31, and the electromagnetic one-way valve 35 is installed on the bottom surface of the drain pipe 33 and the bottom surface of the drain pipe 34 respectively.
[0023] In this embodiment: by setting the mounting shell 31, a closed installation space is provided for the water filter pipe 32, drain pipe 33, and sewage pipe 34. This not only protects the internal components from external environmental corrosion but also prevents impurities from splashing during the separation process. At the same time, it provides a stable cavity environment for the separation of water flow and impurities. The water filter pipe 32, through its alignment design with the sewage hopper 24, can collect impurities and some hot water flowing from the sewage hopper 24. The water and impurities are separated by the surface drainage holes 11 and the filter screen 5. The hot water flows back to the drain pipe 33 through the drainage holes 11 and re-enters the hot water delivery system, avoiding water waste, while the impurities are trapped. Impurities are collected in the filter pipe 32. The drain pipe 33 can guide the clean hot water separated from the filter pipe 32 back to the main pipe, ensuring the continuity of hot water supply and avoiding hot water loss due to sewage discharge. The sewage pipe 34 can quickly discharge the impurities accumulated in the filter pipe 32 by opening the electromagnetic single-way valve 35 at the bottom. The electromagnetic single-way valve 35 controls the opening and closing of the drain pipe 33 and the sewage pipe 34 respectively. It can keep the drain pipe 33 unobstructed and the sewage pipe 34 closed during normal filtration to ensure normal hot water return. It can also close the drain pipe 33 and open the sewage pipe 34 during sewage discharge to prevent impurities from re-entering the pipeline with the returned hot water.
[0024] Specifically, such as Figure 4 As shown, the surface of the water filter pipe 32 is provided with several water leakage holes 11, and a filter screen 5 is fixedly connected to the inner side of the water leakage holes 11.
[0025] Specifically, such as Figure 4 As shown, insertion slots 6 are provided on both sides of the bottom of the connecting pipe 1, and sealing strips 7 are installed on both sides of the top of the connecting plate 21. The sealing strips 7 are engaged with the insertion slots 6.
[0026] In this embodiment: by setting the drain hole 11, the hot water in the filter pipe 32 can quickly penetrate into the mounting shell 31 and then flow back through the drain pipe 33. By setting the filter screen 5, the fine impurities remaining in the filtered water can be further intercepted, preventing fine particles from entering the main pipe with the returned hot water and causing secondary blockage. By setting the insertion groove 6, the sealing strip 7 is provided with installation positioning to prevent the sealing strip 7 from shifting or falling off during assembly, ensuring the accuracy of the sealing position. By setting the sealing strip 7, the gap between the connecting pipe 1 and the connecting plate 21 is filled by the tight snap-fit with the insertion groove 6, effectively preventing hot water from leaking from the joint. At the same time, the high temperature resistant sealing strip 7 can adapt to the high temperature environment of the hot water pipe, avoiding the aging and failure of the sealing strip 7 after long-term use.
[0027] Specifically, such as Figure 4 , Figure 5 As shown, connecting screw holes 8 are provided on both sides of the connecting pipe 1 and on both sides of the top of the connecting plate 21, and a fixing screw 9 is threaded into the inner side of the connecting screw hole 8.
[0028] Specifically, such as Figure 4 As shown, a flow guide cone 10 is welded to the left side of the inner side of the filter ring 23, and the tip of the flow guide cone 10 faces the left side of the filter tube 22.
[0029] In this embodiment: By setting the connecting screw hole 8, the alignment of the fixing screw 9 is ensured, avoiding assembly difficulties caused by misalignment of the screw holes. By setting the fixing screw 9, the connecting pipe 1 and the connecting plate 21 are tightly fixed by the threaded connection, which can resist the impact and vibration generated by the hot water flow, prevent the snap-fit structure from loosening after long-term use, ensure the connection strength between the filter mechanism 2 and the connecting pipe 1, and at the same time, the threaded connection facilitates disassembly and maintenance in the future. By setting the flow guide cone 10, hot water is prevented from directly impacting the filter non-woven fabric of the filter ring 23, reducing the impact force of the water flow on the non-woven fabric, preventing the non-woven fabric from being damaged or the filtration accuracy from decreasing due to long-term impact, and extending the service life of the filter components. At the same time, the diverted water flow can be evenly distributed in the filter pipe 22, so that the water flow flows smoothly through the filter non-woven fabric, avoiding the local water flow velocity being too fast and causing impurities to penetrate the filter layer, thus improving the filtration effect.
[0030] Working principle: First, hot water flows into the connecting pipe 1 of the device from the external hot water pipe. The connecting pipe 1 acts as a carrier to stably guide the hot water to the inner filter mechanism 2. Then, the hot water enters the filter tube 22. As it flows towards the filter ring 23, it first contacts the guide cone 10 on the left side of the inner side of the filter ring 23. The tip of the guide cone 10 faces the left side of the filter tube 22, diverting the hot water that might otherwise concentrate on impacting the filter non-woven fabric into a uniform flow. This guides the water flow smoothly and evenly through the filter non-woven fabric inside the filter ring 23, preventing excessive water flow impact from damaging the non-woven fabric. The filter is damaged, but the filtration area of the non-woven filter is fully utilized. Then, as the hot water flows through the filter, it intercepts impurities such as mud, rust, and fine scale particles, preventing them from entering subsequent pipes. The intercepted impurities fall into the drain hopper 24 at the bottom of the inner side of the filter tube 22 under gravity. The drain hopper 24, with its funnel-shaped structure, directs the impurities to the drain mechanism 3, preventing them from accumulating and clogging the filter channel or adhering to the inner wall of the filter tube 22. Afterwards, the impurities, along with some of the carried materials... Hot water mixed with impurities flows from the bottom of the drain hopper 24 into the filter pipe 32 of the drain mechanism 3. As the hot water carrying small impurities passes through the filter holes, the filter screen 5 inside the drain hole 11 further intercepts the remaining small impurities, achieving separation of water and impurities. The separated clean hot water permeates through the drain hole 11 into the mounting housing 31, then flows into the drain pipe 33 at the bottom right side of the mounting housing 31, and finally returns to the main hot water pipe via the drain pipe 33. This avoids hot water waste and ensures the continuity of hot water delivery. Finally, according to actual usage needs, the operator controls the electromagnetic switch... During normal filtration, the solenoid single-way valve 35 of the drain pipe 33 is open and the solenoid single-way valve 35 of the sewage pipe 34 is closed, ensuring smooth return of clean hot water. When a certain amount of impurities accumulate in the filter pipe 32, the solenoid single-way valve 35 of the drain pipe 33 is closed and the solenoid single-way valve 35 of the sewage pipe 34 is opened. The impurities collected in the filter pipe 32 are quickly discharged from the device through the sewage pipe 34 under the push of gravity and a small amount of residual hot water, completing the impurity cleaning. After the sewage discharge is completed, the initial state of the two valves is restored and the device continues to enter the normal filtration and anti-clogging process.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
