[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0039] In the related art, various dust removal devices are usually used to separate dust. However, the filter elements of these dust removal devices need to be frequently replaced or cleaned, which not only increases maintenance costs but also affects work efficiency.

[0040] In order to solve or improve the problem in the related art that the filter element of the dust removal device needs to be frequently replaced or cleaned, the embodiment of the present invention provides a dust removal device and a cable material production system.

[0041] The following combination Figures 1 to 4 , describing the dust removal device provided in the embodiment of the present utility model.

[0042] Specifically, the dust removal device includes a housing 1 , a rotating shaft 2 and a filter element 3 .

[0043] The box body 1 has a containing cavity 101 , and is provided with an air inlet 102 and an air outlet 103 . It is understandable that the air inlet 102 and the air outlet 103 are both communicated with the containing cavity 101 .

[0044] The rotating shaft 2 is disposed in the accommodating cavity 101 and extends along a first direction X. For example, the first direction X can be the length direction or the width direction of the housing 1. The rotating shaft 2 is rotatably connected to the housing 1. For example, both ends of the rotating shaft 2 are rotatably connected to the two side walls of the housing 1 via bearings.

[0045] The filter element 3 is configured as a cylindrical structure. For example, the filter element 3 can be configured as a filter screen or a filter element. The filter element 3 is sleeved on the outside of the rotating shaft 2 and is connected to the rotating shaft 2 via a connector, allowing the filter element 3 to rotate with the rotating shaft 2. In the second direction Y, the filter element 3 divides the accommodating chamber 101 into an air inlet chamber 1011 and an air outlet chamber 1012. The second direction Y intersects with the first direction X. For example, one of the first direction X and the second direction Y is the length direction of the housing 1, and the other is the width direction of the housing 1. The air inlet 102 is connected to the air inlet chamber 1011, and the air outlet 103 is connected to the air outlet chamber 1012.

[0046] Under operating conditions, housing 1 is used to contain a cleaning liquid, such as water. The cleaning liquid level is set along a third direction Z. The third direction Z, the first direction X, and the second direction Y intersect with each other. For example, the third direction Z, the first direction X, and the second direction Y are perpendicular to each other. The third direction Z can be the height of housing 1. A portion of filter element 3 enters the cleaning liquid, i.e., the portion of filter element 3 is positioned below the liquid level of the cleaning liquid.

[0047] In this embodiment, during use, the gas to be treated can be introduced into the air inlet chamber 1011 of the accommodating chamber 101 through the air inlet 102. After being filtered by the filter element 3, the gas enters the exhaust chamber 1012 and is finally discharged through the exhaust port 103. When the filter element 3 needs to be cleaned, the rotating shaft 2 can be driven to rotate so that the dust-adhered portion of the filter element 3 enters the cleaning liquid in the housing 1, and the cleaning liquid cleans the filter element 3.

[0048] In this way, the dust removal device provided in the embodiment of the present invention has a rotating shaft 2 that is rotatably disposed in the accommodating chamber 101 of the box body 1, and the filter element 3 is mounted on the outside of the rotating shaft 2 through a connecting piece, and the accommodating chamber 101 is divided into an air intake chamber 1011 and an exhaust chamber 1012. During the rotation of the rotating shaft 2, the filter element 3 can enter the cleaning liquid of the box body 1 for cleaning to remove dust on the surface of the filter element 3, thereby eliminating the need to replace the filter element 3 or frequently disassemble and clean it, thereby reducing the maintenance cost of the filter element 3.

[0049] In addition, since the filter element 3 is configured as a cylindrical structure, the gas in the air inlet cavity 1011 can be filtered twice by the two opposite side walls of the filter element 3 when entering the exhaust cavity 1012 through the filter element 3, thereby improving the filtering effect of the gas to be treated.

[0050] In some embodiments provided by the present invention, the connecting member includes a plurality of supporting members 4 .

[0051] The plurality of support members 4 are arranged along the circumference of the rotating shaft 2 , for example, the plurality of support members 4 are evenly arranged along the circumference of the rotating shaft 2 . One end of the support member 4 is connected to the rotating shaft 2 , and the other end of the support member 4 is connected to the inner wall of the filter element 3 .

[0052] In this embodiment, the rotating shaft 2 and the filter element 3 are connected by multiple support members 4, which can improve the connection strength between the filter element 3 and the rotating shaft 2, and make the external force applied to the filter element 3 more balanced, avoiding the situation where the filter element 3 is locally subjected to excessive force, and reducing the possibility of deformation or damage of the filter element 3.

[0053] Optionally, the support member 4 is welded, bonded, connected via a threaded connector, or directly threadedly connected to the rotating shaft 2. Optionally, the support member 4 and the filter member 3 can be welded or bonded.

[0054] refer to Figure 2 and Figure 4 As shown, in some embodiments provided by the present invention, the support member 4 includes a support rod 401 and a support plate 402 .

[0055] The support plate 402 extends along the axial direction of the filter element 3 and is connected to the inner wall of the filter element 3. For example, the support plate 402 can be bonded or welded to the filter element 3.

[0056] One end of the support rod 401 is connected to the rotating shaft 2, for example, the support rod 401 is welded, bonded, connected via a threaded connector, or directly threadedly connected to the rotating shaft 2. The end of the support rod 401 away from the rotating shaft 2 is connected to the support plate 402, for example, the support rod 401 is welded, bonded, connected via a threaded connector, or directly threadedly connected to the support plate 402.

[0057] In this embodiment, the support plate 402 is fitted with the inner wall of the filter element 3, and the support plate 402 extends along the axial direction of the filter element 3. The contact area between the support plate 402 and the filter element 3 is larger, thereby increasing the rigidity of the filter element 3, helping to maintain the shape of the filter element 3 stable during operation, and preventing deformation caused by external pressure or vibration.

[0058] Optionally, at least two support rods 401 are provided between the support plate 402 and the rotating shaft 2 , and the at least two support rods 401 are arranged in sequence along the axial direction of the rotating shaft 2 .

[0059] Such a setting can improve the connection strength between the support plate 402 and the rotating shaft 2, thereby improving the stability of the support plate 402, avoiding the problem of displacement or shaking of the support plate 402, and then maintaining the shape of the filter element 3 stable during operation, preventing deformation caused by external pressure or vibration.

[0060] In some embodiments provided by the present invention, the connecting member further includes a curved plate 5 .

[0061] The curved plate 5 is connected between two adjacent support members 4, for example, the curved plate 5 is connected between two adjacent support members 402. The curved plate 5 is also connected to the inner wall of the filter element 3. Optionally, a curved plate 5 is connected between any two adjacent support members 4.

[0062] In this embodiment, connecting two adjacent support members 4 via a curved plate 5 improves the overall rigidity and strength of the connector, preventing deformation and increasing its load-bearing capacity. Furthermore, the curved plate 5 supports the filter element 3, further increasing the area of ​​support provided by the connector to the filter element 3. This further increases the rigidity of the filter element 3, helping to maintain the shape of the filter element 3 during operation and preventing deformation caused by external pressure or vibration.

[0063] In some embodiments provided by the present invention, the dust removal device further includes a cleaning member 6 .

[0064] The cleaning member 6 is disposed in the accommodating cavity 101 and is connected to the housing 1 . The cleaning member 6 is used to clean the filter member 3 .

[0065] In this embodiment, by providing a cleaning element 6, when impurities on the filter element 3 cannot be removed by rotating the filter element 3 into the cleaning liquid, the filter element 3 can be cleaned by the cleaning element 6 to remove the impurities remaining on the filter element 3, thereby ensuring the filtering capacity of the filter element 3.

[0066] Optionally, the cleaning member 6 can be configured as a brush, a cleaning cloth or a sponge.

[0067] In some embodiments provided by the present invention, the dust removal device further includes a linear drive device 7 .

[0068] The linear drive device 7 is disposed in the accommodating chamber 101 and is connected to the housing 1. The linear drive device 7 is in transmission connection with the cleaning element 6. The driving direction of the linear drive device 7 intersects the outer wall of the filter element 3. The linear drive device 7 is used to drive the cleaning element 6 toward or away from the filter element 3.

[0069] In this embodiment, by providing a linear drive device 7 in transmission connection with the cleaning element 6, when the filter element 3 needs to be cleaned, the linear drive device 7 can drive the cleaning element 6 to offset the filter element 3 to ensure the filtering capacity of the filter element 3.

[0070] When the filter element 3 does not need to be cleaned, the linear drive device 7 can drive the cleaning element 6 to disengage from the filter element 3 to reduce the resistance of the cleaning element 6 to the filter element 3, so that the filter element 3 rotates more smoothly, thereby reducing the power consumption required to rotate the filter element 3.

[0071] With such arrangement, the linear drive device 7 can be controlled as needed to drive the cleaning element 6 to contact or separate from the filter element 3, so that the dust removal device can be used more flexibly.

[0072] Optionally, the linear drive device 7 can be configured as a pneumatic cylinder, an oil cylinder or an electric cylinder.

[0073] Optionally, the cleaning member 6 can be connected to the linear drive device 7 via a threaded fastener. This arrangement makes it easy to remove the cleaning member 6 from the linear drive device 7, so that the cleaning member 6 can be easily replaced, repaired or cleaned.

[0074] Optionally, one of the cleaning member 6 and the housing 1 is provided with a guide sleeve 8, and the other is provided with a guide rod 9. The guide rod 9 and the guide sleeve 8 are slidably engaged with each other, and the relative sliding direction between the guide rod 9 and the guide sleeve 8 is parallel to the driving direction of the linear drive device 7.

[0075] In this embodiment, the cleaning member 6 is guided by providing a guide sleeve 8 and a guide rod 9 that are slidably fitted. On the one hand, the connection rigidity between the cleaning member 6 and the housing 1 can be increased, thereby improving the operational stability of the cleaning member 6.

[0076] On the other hand, the sliding fit between the guide sleeve 8 and the guide rod 9 can effectively resist the lateral force, prevent the cleaning member 6 from generating lateral displacement during the cleaning process, and ensure the stability and reliability of the cleaning process.

[0077] The sliding fit between the guide sleeve 8 and the guide rod 9 can also share the lateral force exerted on the linear drive device 7, thereby extending the service life of the linear drive device 7.

[0078] In some embodiments provided by the present invention, the dust removal device further includes a nozzle 10 .

[0079] The nozzle 10 is disposed in the accommodating cavity 101 , and a spraying direction of the nozzle 10 intersects with an outer wall of the filter element 3 . The nozzle 10 is used to spray cleaning liquid onto the filter element 3 .

[0080] In this embodiment, when the impurities on the filter element 3 cannot be removed by rotating the filter element 3 into the cleaning liquid, the cleaning liquid can be sprayed onto the filter element 3 through the nozzle 10 to clean the filter element 3 and remove the impurities remaining on the filter element 3 to ensure the filtering capacity of the filter element 3.

[0081] Furthermore, the spraying direction of the nozzle 10 and the driving direction of the linear drive device 7 intersect at the same position on the surface of the filter element 3. In this arrangement, the nozzle 10 can simultaneously flush the filter element 3 and the cleaning element 6 during the spraying process to ensure that the filter element 3 and the cleaning element 6 are clean.

[0082] In some embodiments provided by the present invention, the dust removal device further includes a water pump 11 .

[0083] The water pump 11 is connected to the nozzle 10 and is used to pump cleaning liquid to the nozzle 10. For example, the liquid inlet of the water pump 11 is connected to the container of the cleaning liquid, and the liquid outlet of the water pump 11 is connected to the nozzle 10.

[0084] With such an arrangement, the dust removal device does not need to be connected to an external water pump, and the cleaning liquid can be pumped to the nozzle 10 to complete the flushing of the filter element 3 or the cleaning element 6.

[0085] In some embodiments provided by the present invention, the dust removal device further includes a cover 13. In the third direction Z, an opening is provided at a position where the box body 1 and the filter element 3 are opposite to each other, and the cover 13 can be opened and closed to cover the opening.

[0086] In this embodiment, an opening is provided between the housing 1 and the filter element 3 to facilitate disassembly, repair and maintenance of the filter element 3. A cover 13 is provided to cover the opening to seal the opening and prevent gas from leaking from the opening.

[0087] Optionally, the cover 13 may be detachably connected to the box body 1 via threaded fasteners.
