Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning and filtration technology, specifically to a pipeline rust filtration structure. Background Technology

[0002] Most chemical process pipelines are made of steel. In humid environments, the inside of these pipelines rusts. As the medium flows through, it erodes the inner walls of the pipeline, causing some rust to flake off and mix with the medium, resulting in substandard processed media. Ordinary filters have drawbacks: filtering small impurities requires fine screens, which creates excessive fluid resistance in the pipeline, and large amounts of impurities can clog the screens, leading to poor filtration. Utility Model Content

[0003] In view of the defects of the existing technology, the purpose of this utility model is to provide a pipeline rust filtering structure to remove rust generated in pipelines, minimize the resistance to fluid in the pipeline, and prevent product contamination.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pipe rust filtering structure, including a filter section, the two ends of which are detachably connected to a metal pipe through flanges, the filter section including a pipe body, the inner wall of which is provided with magnets for adsorbing rust, the magnets being evenly distributed along the length of the inner wall of the pipe body, and the magnets being embedded in the inner wall of the pipe body.

[0005] Furthermore, the magnet is a bar magnet and / or a ring magnet.

[0006] Furthermore, the inner wall of the tube is provided with a plurality of axially extending strip-shaped assembly grooves, which are evenly distributed circumferentially on the inner wall of the tube. An annular assembly groove is provided at the end of the inner wall of the tube. Strip magnets are embedded in the strip-shaped assembly grooves, and annular magnets are embedded in the annular assembly grooves.

[0007] Furthermore, the magnet is a bar magnet, which is evenly distributed circumferentially on the inner wall of the tube, and there are no fewer than four bar magnets.

[0008] Furthermore, the metal pipe is provided with hand valves at both ends of the filter section for cutting off the filter section.

[0009] Furthermore, the diameter of the filter section is the same as the diameter of the metal pipes at both ends, and the axis of the filter section is on the same straight line as the axis of the metal pipes.

[0010] Furthermore, the pipe body is a steel pipe.

[0011] The beneficial effects of this invention are as follows: A filter section embedded with a magnet replaces the traditional filter; this section is removable for cleaning or replacement, facilitating maintenance. Rust is adsorbed onto the inner wall of the pipe without affecting the flow of the medium within the pipe. Furthermore, by controlling the length of the section, long-distance adsorption and cleaning can be achieved, resulting in excellent cleaning performance. Attached Figure Description

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Example 1

[0020] See appendix Figure 1-3A pipe rust filtering structure includes a filter section 1, which is detachably connected to a metal pipe 2 at both ends via flanges. Hand valves 3 for cutting off the filter section 1 are provided at both ends of the metal pipe 2. The filter section 1 includes a steel pipe body 4. The inner wall of the steel pipe body 4 is provided with bar magnets 5 and annular magnets 6 for adsorbing rust. Four axially extending strip-shaped mounting grooves are provided on the inner wall of the pipe body, evenly distributed circumferentially. Four bar magnets 5 are embedded in the four mounting grooves. The length of the mounting grooves is adapted to the axial length of the steel pipe body 4, ensuring that magnets are present along the axial length of the steel pipe body 4. An annular mounting groove is provided at the end of the inner wall of the steel pipe body 4, and an annular magnet 6 is embedded in the annular mounting groove. The annular magnet 6 at the end is used to collect iron filings.

[0021] Furthermore, the diameter of the filter section 1 is the same as the diameter of the metal pipes 2 at both ends, and the axis of the filter section 1 is on the same straight line as the axis of the metal pipes 2.

[0022] In this embodiment, a short section is installed on the metal pipe 2. The short section is connected to the upstream and downstream pipelines via a flange. Several strong magnetic strip magnets are embedded inside the short section, and a ring of strong magnetic magnets is embedded at the end. Due to the strong magnetic force, iron filings are attracted to the inner wall of the magnets. Because of the strong magnetic force and the ability to extend the length of the short section, the cleaning effect on iron filings in the pipeline medium is excellent. This avoids the high-quality medium being affected by pipeline impurities. Moreover, the short section can be disassembled for easy cleaning and can be used for a long time. Since the strong magnets are not affected by media corrosion, they can maintain a highly efficient cleaning effect for a long time. Because impurities are attracted to the inner wall of the short section, it will not become clogged after long-term use like an old-fashioned mesh filter, thus affecting the flow rate and allowing for long-term use.

[0023] Compared to traditional filter screen cleaning methods, the filter section in this embodiment extends the cleaning distance. Furthermore, the use of a short section for filtration does not require changing the direction of media flow or hindering media flow, thus ensuring the stability of media flow rate and velocity at the short section.

The length of the bar mounting grooves is adapted to the axial length of the steel pipe body 4 to ensure that there are magnets along the axial length of the steel pipe body 4. The end of the inner wall of the steel pipe body 4 is provided with a ring mounting groove, and a ring magnet 6 is embedded in the ring mounting groove.
