Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a pipeline filter element structure. Background Technology

[0002] Pipeline filter cartridges are water filtration devices where filter cartridges are packed and assembled within a pipe. Existing pipeline filter cartridges are prone to freezing after use in winter or cold weather, as residual moisture inside the filter cartridge tube can easily freeze, making it impossible to disassemble or causing the filter cartridge housing to crack and break. Current methods typically involve directly pouring hot water into the filter cartridge to heat it; however, excessively high water temperatures directly contacting the filter material can easily damage the filter elements.

[0003] Based on this, the present invention designs a pipeline filter element structure to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a pipeline filter element structure to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline filter element structure, comprising: a base, a main body, an outer frame, a top connector, a filter element tube, and a top cover; the outer frame is integrally formed on the outer wall of the main body, and an annular cavity is formed between the outer frame and the main body; The top of the main body is open and the filter tube is inserted into the main body. The top connector is fixedly connected to the top of the main body. The top of the top connector has a funnel-shaped concave hole that connects to the opening of the main body. The top connector has a through hole in its recessed hole. A connecting pipe is fixedly connected between the top connector and the outer frame. One end of the connecting pipe is connected to the through hole of the top connector. The top cover is detachably installed in the recessed hole of the top connector, and the height of the top cover after installation is lower than the through hole, so that the recessed hole forms a flow guiding space to the connecting pipe.

[0006] Preferably, the outer wall of the main tube is fixedly connected to a water inlet connector, and the bottom of the main tube is fixedly connected to a water outlet connector, with the water inlet connector connected to the main tube located above the filter element tube.

[0007] Preferably, the filter tube has perforated plates that can be detachably installed at both the top and bottom, and a filter element is installed inside the filter tube.

[0008] Preferably, a valve pipe is fixedly connected to the bottom of the outer frame, and the valve pipe is used to drain the liquid in the annular cavity of the outer frame.

[0009] Preferably, a base is fixedly connected to the bottom of the main body to support the installation and use of the main body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The outer frame's annular cavity provides a unified external heating space for the main body and filter tube, ensuring stable and safe ice melting. Hot water will not directly contact the filter material, avoiding damage to the filter due to high temperatures. Furthermore, the hot water pouring process utilizes the funnel-shaped concave hole on the top connector, preventing hot water from spilling out and enhancing safety. Attached Figure Description

[0014] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 The present invention provides a technical solution: a pipeline filter element structure, including: a base 1, a main body 2, an outer frame 7, a top connector 8, a filter element tube 5, and a top cover 12; the outer frame 7 is integrally formed on the outer wall of the main body 2, and an annular cavity is formed between the outer frame 7 and the main body 2. The top of the main body 2 is open and the filter tube 5 is inserted into the main body 2. The top connector 8 is fixedly connected to the top of the main body 2. The top of the top connector 8 has a funnel-shaped concave hole that connects to the opening of the main body 2. A through hole 10 is provided in the recess of the top connector 8. A connecting pipe 9 is fixedly connected between the top connector 8 and the outer frame 7. One end of the connecting pipe 9 is connected to the through hole 10 of the top connector 8. The top cover 12 is detachably installed in the recess of the top connector 8, and the height of the top cover 12 after installation is lower than the through hole 10, so that the recess forms a flow guiding space to the connecting pipe 9. The outer frame 7 and the main body 2 form an annular cavity. The concave hole of the top connector 8 introduces hot water into the cavity through the through hole 10 and the connecting pipe 9, so that the outer side of the main body 2 and the filter element tube 5 is heated. The funnel-shaped concave hole makes it more stable when pouring hot water and prevents hot water from spilling out. The top cover 12 is disassembled and assembled by threaded connection. The whole system realizes external ice melting heating of the filter element at low temperature, avoids hot water contact with the filter element material, protects the filter element and improves the reliability of winter use.

[0016] More preferably, the outer wall of the main body 2 is fixedly connected to a water inlet connector 3, and the bottom of the main body 2 is fixedly connected to a water outlet connector 4. The position where the water inlet connector 3 connects to the main body 2 is located above the filter tube 5. The inlet connector 3 is located above the filter tube 5, allowing water to flow from top to bottom through the filter tube 5 and be discharged from the bottom through the outlet connector 4, forming a stable gravity-assisted flow and ensuring the integrity of the filtration path.

[0017] More preferably, the filter tube 5 has a perforated plate 6 that can be detachably installed at both the top and bottom, and a filter element is installed inside the filter tube 5; The perforated plates 6 at the top and bottom of the filter tube 5 are detachable and can be installed by threaded connection. The filter material is placed inside the filter tube 5, and the filter can be replaced.

[0018] More preferably, a valve pipe 11 is fixedly connected to the bottom of the outer frame 7, and the valve pipe 11 is used to drain the liquid in the annular cavity of the outer frame 7; A valve pipe 11 is installed at the bottom of the outer frame 7 to drain hot water or accumulated liquid in the annular cavity, so as to facilitate the drainage of residual water after melting and prevent refreezing.

[0019] In a further preferred embodiment, the bottom of the main body 2 is fixedly connected to the base 1 to support the installation and use of the main body 2.

[0020] One specific application of this embodiment is as follows: hot water at 50-90°C is slowly poured onto the top cover 12 inside the funnel-shaped concave hole. The funnel-shaped concave hole makes the hot water more stable when pouring, and it is not easy for hot water to spill out. Then, the through hole 10 allows the poured hot water to flow into the connecting pipe 9. Through the connecting pipe 9, the hot water is introduced into the annular cavity between the outer frame 7 and the main body 2. The hot water only flows in the cavity of the outer frame 7 and does not come into contact with the inside of the filter tube 5 or the filter material, so as to avoid damaging the filter. The hot water in the annular cavity surrounds the outer wall of the main body 2, forming a surrounding heating, which makes the ice inside the main body 2 and the filter tube 5 melt quickly. After the ice melts, the valve pipe 11 at the bottom of the outer frame 7 can be opened to drain the hot water in the cavity.
