[0001] The present disclosure relates to the technical field of compressed air purification, and in particular to an iron filings adsorption device and a compressed air delivery pipe assembly. Background Art

[0002] Compressed air is often used as a source of energy and power.

However, for the iron filings with very small particles, the filtering effect of the filter is not ideal, and the iron filings contained in the compressed air are easy to adhere to the filter, blocking the filter holes, resulting in poor filtering effect of the filter, affecting the filtering effect of the compressed air.

[0036] The specific embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0037] In the description of the present disclosure, it is necessary to understand that the terms "upper", "lower", "inside", "outside", etc., indicating orientation or positional relationships, are defined based on the drawing directions shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation on the present disclosure.

[0038] In the present disclosure, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order and importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0039] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0040] like Figures 1 to 6 As shown, the present application provides an iron chip adsorption device 100, including a frame 10 and a magnetic plate 20. The frame 10 is used to be detachably installed in a compressed air delivery pipe 300, and is used to be arranged upstream of a filter screen 200 in the compressed air delivery pipe 300. The magnetic plate 20 is located in the frame 10 and is rotatably connected to the frame 10. The magnetic plate 20 is used to adsorb iron chips in the compressed air flowing through the iron chip adsorption device 100.

[0041] Through the above technical solution, the iron filings adsorption device 100 is arranged upstream of the filter 200, that is, arranged on the side where the compressed air enters the filter 200, and can adsorb the iron filings carried by the compressed air through the magnetic suction plate 20 before the compressed air reaches the filter 200, so that when the compressed air passes through the filter 200, there will not be much iron filings, thereby reducing the content of iron filings in the compressed air passing through the filter 200, reducing the possibility of the filter 200 being blocked by iron filings, increasing the service life of the filter 200, and improving the filtering effect of the compressed air. In addition, for iron filings that are too small to be filtered by the filter 200, the magnetic suction plate 20 can also magnetically adsorb them to improve the filtering effect of the compressed air.

[0042] In addition, the magnetic plate 20 is rotatably connected to the frame 10, so that the magnetic plate 20 can be rotated as needed, thereby forming a flow channel that is convenient for absorbing iron filings in the compressed air, so that the magnetic plate 20 can better absorb iron filings in the compressed air.

[0043] Optionally, the cross-section of the compressed air delivery pipe 300 may be square, circular or other suitable structures, and the frame 10 of the iron chip adsorption device may also be set to be square, circular or other suitable structures so that the size and shape of the frame 10 are compatible with the size and shape of the compressed air delivery pipe 300.

[0044] Optionally, the frame 10 can be removably installed in the compressed air delivery pipe 300 in any appropriate manner. For example, an interference fit can be formed between the frame 10 and the inner wall of the compressed air delivery pipe 300; or, a fastener can be provided inside the compressed air delivery pipe 300, and the fastener is engaged with the frame 10 to fix the position of the iron chip adsorption device 100 in the compressed air delivery pipe 300.

[0045] In some embodiments, the magnetic plate 20 can be composed of an iron plate and a soft magnet device, so that the magnetic plate 20 has a certain strength and hardness and will not break due to rotation, and can effectively absorb iron filings in the compressed air.

[0046] In this disclosure, Figures 1 to 3 As shown, the magnetic plate 20 can be formed as a corrugated plate, and the corrugation direction of the corrugated plate is set to be along the axial direction of the compressed air delivery pipe 300. Such a setting can increase the surface area of ​​the magnetic plate 20, thereby increasing the contact surface between the magnetic plate 20 and the compressed air, so that the magnetic plate 20 can better absorb iron filings in the compressed air.

[0047] The corrugation direction of the corrugated plate is set along the axial direction of the compressed air delivery pipe 300, which means that the crests and troughs formed by the corrugations are set at an angle to the flow direction of the compressed air, for example, the crests and troughs are arranged vertically to the flow direction of the compressed air.

[0048] In this disclosure, Figure 2 and Figure 3 As shown, the magnetic plate 20 may have a first side and a second side opposite to each other along the axial direction of the compressed air delivery pipe 300, the second side is located between the first side and the filter screen 200, and the first side and / or the second side are folded to form a flange 21. In this way, the flange 21 can block the flowing compressed air, that is, the flange 21 can decelerate the flowing compressed air, so that the compressed air stays on the magnetic plate 20 for a longer time, so that the iron scrap adsorption device 100 has a better effect of adsorbing iron scraps.

[0049] In the present disclosure, in order to facilitate the cleaning of iron filings on the magnetic plate 20, the iron filing adsorption device 100 may further include a receiving box 50, which is located in the frame 10 and detachably mounted on the bottom of the frame 10, and has a receiving groove 51, the opening of which faces the magnetic plate 20. The function of the receiving box 50 is to collect iron filings on the magnetic plate 20, so that the iron filings on the magnetic plate 20 will not be scattered in the compressed air delivery pipe 300, thereby reducing the damage of the iron filings to the filter 200.

[0050] In some embodiments, the iron filings adsorption device 100 can be set in a position near the pipe mouth of the compressed air delivery pipe 300. When it is necessary to clean the iron filings on the magnetic suction plate 20, the magnetic suction plate 20 can be rotated to be roughly parallel to the vertical direction. The iron filings on the magnetic suction plate 20 will fall into the receiving box 50 after being removed. The operator can take out the receiving box 50 from the position of the pipe mouth, clean the receiving box 50, and then put it back into the iron filings adsorption device. The operator can also take out the entire iron filings adsorption device 100, and then remove the receiving box 50 to clean the iron filings in the receiving box 50. This can prevent iron filings from scattering in the compressed air delivery pipe 300, and the receiving box 50 can be reused.

[0051] In some embodiments, the receiving groove 51 can be set as a U-shaped groove to facilitate the collection of iron filings and prevent the iron filings from falling.

[0052] In this disclosure, Figure 1 As shown, the iron scrap adsorption device 100 may further include a connecting rod 30 and a rotating knob 40, the magnetic plate 20 is rotatably connected to the frame 10 through the connecting rod 30, the rotating knob 40 is rotatably embedded in the frame 10, and one end of the connecting rod 30 is connected to the rotating knob 40. The rotating knob 40 is provided to facilitate the rotation of the magnetic plate 20 to adjust the angle of the magnetic plate 20, and the rotating knob 40 is embedded in the frame 10 to prevent the rotating knob 40 from interfering with the inner wall of the compressed air delivery pipe 300.

[0053] In some embodiments, since the interior of the compressed air delivery pipe 300 is narrow, it is inconvenient for the operator to operate the rotating knob 40 in some areas. Therefore, when using, the angle of the magnetic suction plate 20 can be adjusted to the right position first, and then the iron chip adsorption device 100 can be installed into the compressed air delivery pipe 300. After the iron chip adsorption device 100 is installed, there is no need to adjust the angle of the magnetic suction plate 20 by rotating the knob 40.

[0054] In this disclosure, Figure 4 As shown, the connecting rod 30 includes a first connecting section 31, a second connecting section 32 and a third connecting section 33. The first connecting section 31 is connected to a rotating knob 40 rotatably embedded on one side of the frame 10, the second connecting section 32 is rotatably connected to the other side of the frame 10, the third connecting section 33 is connected between the first connecting section 31 and the second connecting section 32, and the magnetic plate 20 is connected to the third connecting section 33. In this way, both ends of the connecting rod 30 (i.e., the first connecting section 31 and the second connecting section 32) can be rotatably connected to the frame 10 to facilitate the rotation of the magnetic plate 20.

[0055] In some embodiments, the third connecting segment 33 is configured as a rod with a circular cross-section, and the third connecting segment 33 and the magnetic plate 20 can be fixedly connected so that the magnetic plate 20 can be driven to rotate when the third connecting segment 33 rotates.

[0056] In the present disclosure, in order to enable the connecting rod 30 to drive the magnetic plate 20 to rotate, as shown in FIG. Figure 3 and Figure 4 As shown, a bar hole 22 for the third connecting section 33 to pass through is formed on the magnetic attraction plate 20, the cross section of the third connecting section 33 is formed to be non-circular, and the inner contour of the bar hole 22 is adapted to the outer contour of the third connecting section 33. In this way, the part of the third connecting section 33 and the bar hole 22 that is matched to each other has at least a structure that prevents the relative movement between the two, such as an edge, to ensure that the connecting rod 30 will not slip between the bar hole 22 of the magnetic attraction plate 20 when rotating.

[0057] Furthermore, the third connecting section 33 is plugged into the strip hole 22 , so when the magnetic plate 20 is damaged, the magnetic plate 20 can be taken out and replaced with a new one, or when the connecting rod 30 is damaged, the connecting rod 30 can be replaced alone to reduce waste.

[0058] In some embodiments, in order to ensure that the strip hole 22 can pass through one of the first connecting section 31 or the second connecting section 32, the cross-sectional profile of the third connecting section 33 is at least larger than one of the first connecting section 31 or the second connecting section 32 to facilitate the strip hole 22 to pass through the third connecting section 33.

[0059] In some embodiments, the rotating knob 40 is embedded in the frame 10 and forms friction with the frame 10 or has a locking structure, that is, the rotating knob 40 can rotate relative to the frame 10, but when no force is applied to the rotating knob 40, the rotating knob 40 and the frame 10 can be relatively fixed.

[0060] In the present disclosure, in order to ensure the magnetic attraction effect of the iron chips adsorption device, as Figure 1 As shown, multiple magnetic plates 20 can be provided, and multiple magnetic plates 20 are spaced apart in the up and down directions. In this way, multiple airflow channels can be formed between the multiple magnetic plates 20, and each magnetic plate 20 can rotate. The rotation of multiple magnetic plates 20 can adjust the size of the airflow space of the compressed air, and the speed of the airflow can be controlled. If necessary, the angle of the magnetic plate 20 can be rotated to reduce the angle between the magnetic plate 20 and the flow direction of the compressed air, thereby reducing the flow rate of the compressed air to improve the magnetic attraction effect of the iron chip adsorption device 100 on the compressed air. In addition, multiple magnetic plates 20 expand the adsorption area and ensure the adsorption efficiency.

[0061] The up-down direction of the frame 10 refers to a direction perpendicular to the side of the frame 10 , for example, a direction perpendicular to the bottom plate 14 described below.

[0062] In this disclosure, Figure 1 As shown, in an embodiment where the frame 10 is a square structure, the frame 10 may include a first side panel 11, a second side panel 12, a top panel 13, and a bottom panel 14, wherein two ends of the top panel 13 are connected to the upper end of the first side panel 11 and the upper end of the second side panel 12, and two ends of the bottom panel 14 are connected to the lower end of the first side panel 11 and the lower end of the second side panel 12, and the magnetic plate 20 is rotatably connected to the first side panel 11 and the second side panel 12.

[0063] In the present disclosure, the first side plate 11 and the second side plate 12 are parallel to each other, the top plate 13 and the bottom plate 14 are parallel to each other, and at least one of the first side plate 11 and the second side plate 12 is detachably connected to the top plate 13 and the bottom plate 14. In this way, it is convenient to disassemble and replace the magnetic plate 20.

[0064] For example, the first side plate 11 is detachably connected to the top plate 13 and the bottom plate 14. When the magnetic plate 20 needs to be removed, the first side plate 11 is first removed, and then the magnetic plate 20 is removed from the connecting rod 30, and then the new replacement magnetic plate 20 is inserted into the connecting rod 30, thereby completing the disassembly and replacement of the magnetic plate 20.

[0065] According to the second aspect of the present disclosure, a compressed air delivery pipe assembly is provided, comprising a compressed air delivery pipe 300, a filter screen 200, and an iron filings adsorption device 100. The iron filings adsorption device 100 and the filter screen 200 are both arranged in the compressed air delivery pipe 300, and the iron filings adsorption device 100 is located upstream of the filter screen 200. In this arrangement, after the compressed air passes through the pipe mouth of the compressed air delivery pipe 300, it passes through the iron filings adsorption device 100 and the filter screen 200 in sequence. When the compressed air passes through the iron filings adsorption device 100, the fine iron filings in the compressed air can be adsorbed by the iron filings adsorption device 100, thereby reducing the content of iron filings in the compressed air. When the compressed air passes through the filter screen 200 again, the risk of iron filings clogging the mesh of the filter screen 200 can be reduced.

[0066] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0067] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction, and the present disclosure will not further explain various possible combinations.

[0068] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
