Description

Technical Field

[0001] This utility model relates to the structural design for removing rust from the inside of chemical pipelines, specifically to a pipeline rust removal tool, belonging to the field of pipeline filtration technology. 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 rust to flake off and mix with the medium, resulting in substandard processed media. To address this problem, filters are typically installed. However, ordinary filters have drawbacks: filtering small impurities requires fine mesh, which creates excessive fluid resistance in the pipeline; moreover, impurities can clog the filter, leading to poor filtration. Utility Model Content

[0003] In view of the technical drawbacks of the aforementioned filtration methods for removing rust from process pipelines, the purpose of this utility model is to provide a pipeline rust removal fixture. The fixture is designed with a filtration structure for the pipeline to remove rust generated in the pipeline, minimize fluid resistance within the pipeline, and prevent product contamination.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a pipe rust removal tool, including a pipe, a filter mechanism, and several valves connected in the filter mechanism and between the filter mechanism and the pipe; the filter mechanism includes: a magnetic suction filter unit and a filter; the magnetic suction filter unit and the filter, the magnetic suction filter unit and the pipe, and the filter and the pipe are all connected by valves, thereby forming an integral pipe filtration structure;

[0005] Furthermore, the valves are manual valves, and the number of manual valves is at least three; one manual valve is located between the magnetic filter unit and the filter, connecting the filter mechanism together; the other two manual valves are located at both ends of the filter mechanism and are respectively connected to the pipeline.

[0006] Furthermore, the magnetic filtration unit and the filter constitute a secondary filtration mechanism for the pipeline;

[0007] Furthermore, the magnetic filtration unit includes a short section and a magnetic unit; both ends of the short section are connected to two adjacent hand valves via flanges; the magnetic unit includes an insulated copper coil, a protective cover, and a current regulator; the insulated copper coil is evenly wound in a fixed direction on the outer diameter surface of the short section, and the two ends of the insulated copper coil are led out and connected to the output terminals of the current regulator, the input terminal of the current regulator is connected to an external DC power supply; the protective cover is disposed outside the insulated copper coil.

[0008] Furthermore, the protective cover is formed by bending two insulating plates to create a halved cylindrical cover; each insulating plate, after being bent, forms a cover unit of the protective cover, and the two cover units are fixed by bolts after being joined together on the outside of the short section with the insulated copper coil wound around it; wherein, the specifications (inner diameter, curvature) of the cylindrical cover are set to match the specifications and dimensions of the short section during manufacturing.

[0009] Furthermore, several bolts are evenly arranged at the docking position of the two cover units along the axial length of the protective cover, and the two cover units are connected together by the bolts.

[0010] Furthermore, the number of bolts at each joint between the two cover units is evenly distributed, and the specific number is adjusted according to the specific length of the protective cover.

[0011] Specifically, in this scheme, the number of bolts at each joint between the two cover units is set to 3.

[0012] Furthermore, the current regulator is model HD-225C, with a power supply voltage of 220 volts and an output voltage of 110 volts.

[0013] When the aforementioned magnetic filter unit is in use, a DC power supply is applied to the input terminal of the regulator, and the current output to the coil is adjusted. As the current flows through the coil, a magnetic field is generated, which causes the short section to generate a magnetic force, and iron filings will be attracted to the inner wall of the pipeline. At the same time, the magnitude of the magnetic force generated in the short section can be adjusted by adjusting the current regulator. The magnitude of the magnetic force can be adjusted according to the specific situation of iron filings in the pipeline medium to improve the cleaning effect of iron filings in the pipeline medium. When enough impurities are attracted, the current is adjusted to zero amps. Due to the loss of magnetism, the impurities will fall off and be removed from the pipeline by the filter removal, thereby reducing the direct clogging of the filter by impurities.

[0014] Furthermore, the filter is a Y-type filter structure, with its two ends connected to the two adjacent hand valves by flanges;

[0015] Furthermore, the hand valve is connected to the pipeline via a flange.

[0016] In the above structure, both the short section and the filter are detachable. The short section can be disassembled for easy cleaning and long-term use; the filter can be easily disassembled to remove impurities when too much is adsorbed in the pipeline; it is easy to use.

[0017] The beneficial effects of this utility model's pipe rust removal fixture are:

[0018] This tooling modifies the pipeline filtration structure to minimize fluid resistance within the pipeline, prevent product contamination, and greatly improve the rust removal effect. It also overcomes the shortcomings of traditional filtration methods, such as excessive fluid velocity and filter clogging, which result in poor filtration performance. Attached Figure Description

[0024] 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.

[0025] like Figure 1 The illustrated pipe rust removal fixture includes a pipe 1, a filter mechanism, and several valves connected in the filter mechanism and between the filter mechanism and the pipe 1. The filter mechanism includes a magnetic filter unit and a filter 2. The magnetic filter unit and the filter 2, the magnetic filter unit and the pipe 1, and the filter 2 and the pipe 1 are all connected by valves to form an integral pipe filtration structure.

[0026] The valve is a manual valve 2, and there are at least three manual valves 2; one manual valve 2 is located between the magnetic suction filter unit and the filter 2, connecting the filter mechanism together; the other two manual valves 2 are located at both ends of the filter mechanism and are respectively connected to the pipe 1.

[0027] The magnetic filtration unit and filter 2 constitute a two-stage filtration mechanism for the pipeline;

[0028] The magnetic filtration unit includes a short section 4 and a magnetic unit. Both ends of the short section 4 are connected to two adjacent hand valves 3 via flanges 9. The magnetic unit includes an insulated copper coil 5, a protective cover 6, and a current regulator 7. The insulated copper coil 6 is evenly wound in a fixed direction on the outer diameter surface of the short section 4. The two ends of the insulated copper coil 5 are led out and connected to the output terminals of the current regulator 7. The input terminal of the current regulator 7 is connected to an external DC power supply. The protective cover 6 is located outside the insulated copper coil 5. The protective cover 6 is a halved cylindrical cover formed by bending two insulating plates. Each bent insulating plate forms a cover unit of the protective cover 6. The two cover units are joined together outside the short section 4 with the insulated copper coil 5 wound around it and fixed with bolts 8. The cylindrical cover's specifications (inner diameter, curvature) are adapted to the dimensions of the short section 4 during manufacturing.

[0029] Furthermore, several bolts 8 are evenly arranged along the axial length of the protective cover 6 at the docking position of the two cover units, and the two cover units are connected together by the several bolts 8.

[0030] Furthermore, the number of bolts 8 at each joint between the two cover units is evenly distributed, and the specific number is adjusted according to the specific length of the protective cover 6.

[0031] Specifically, in this design, the number of bolts 8 at each joint between the two cover units is set to 3. Specifically, at the joint on the same side of the two cover units, corresponding extensions for the bolts 8 to pass through are provided, and bolt holes 10 matching the bolts are opened on the extensions.

[0032] The current regulator 7 mentioned is model HD-225C, with a power supply voltage of 220 volts and an output voltage of 110 volts.

[0033] When the aforementioned magnetic filter unit is in use, a DC power supply is applied to the input terminal of the regulator 7, and the current output is adjusted to the coil 5. As the current flows through the coil 5, a magnetic field is generated, which causes the short section 4 to generate a magnetic force, and iron filings will be attracted to the inner wall of the pipeline. At the same time, the magnitude of the magnetic force generated in the short section 4 can be adjusted by adjusting the current regulator 7. The magnitude of the magnetic force can be adjusted according to the specific situation of iron filings in the pipeline medium to make the cleaning effect of iron filings in the pipeline medium better. When enough impurities are attracted, the current is adjusted to zero amps. Due to the loss of magnetism, the impurities will fall off and be removed through the filter 2 to remove the impurities in the pipeline, thereby reducing the direct blockage of the filter 2 by impurities.

[0034] The filter 2 is a Y-type filter structure, and its two ends are connected to the two adjacent hand valves 3 by flanges 9 respectively;

[0035] The hand valve 3 is connected to the pipe 1 by a flange 9.

[0036] In the above structure, both the short section 4 and the filter 2 are detachable. The short section 4 can be disassembled for easy cleaning and long-term use; the filter 2 can be easily disassembled to remove impurities when too many impurities are adsorbed in the pipe 1; it is convenient to use.
