[0032] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0033] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" 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 a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0035] The term "multiple" as used in the present application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0036] In the prior art, a data center includes at least one accommodation room, which may include a computer room, an MAU clean room, an outdoor water-cooling room, etc. The accommodation room is provided with a fresh air inlet. The filter provided at the fresh air inlet is usually fixed and is usually not removed for cleaning. Since the filter has a large area, manual cleaning is time-consuming and laborious, and the labor cost is high.

[0037] In view of this, the present application provides a filter device. When it is detected that the air pressure difference between the air inlet side and the air outlet side of the filter is greater than the preset air pressure difference, the control system controls the driving mechanism to drive the filter to rotate, and moves the part of the filter located on the inner side of the fresh air inlet (the clean part) to the fresh air inlet, and the part of the filter with debris attached to it is moved to the inner side of the fresh air inlet. While the filter rotates, the cleaning mechanism can clean the filter in preparation for the next rotation to the fresh air inlet.

[0038] The structure of the filter device according to the embodiment of the present application will be described below with reference to the accompanying drawings.

[0039] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides a filter device 100 for installation at a fresh air inlet of a receiving room of a data center. The filter device 100 includes a filter 10, a transmission mechanism 20, a drive mechanism 30, a wind pressure detection component 40, a cleaning mechanism 50 and a control system 60.

[0040] The filter screen 10 is connected end to end. The filter screen 10 is a porous structure, which can facilitate air to pass through and block debris to filter the air entering the fresh air inlet.

[0041] The filter screen 10 may also be called a gauze screen, and the material of the filter screen 10 may be nylon, stainless steel, or other materials.

[0042] The transmission mechanism 20 includes a driving shaft 21 and a driven shaft 22. The filter 10 is sleeved on the driving shaft 21 and the driven shaft 22. A portion of the filter 10 is configured to block the fresh air inlet. The filter 10 is sleeved on the driving shaft 21 and the driven shaft 22, and the filter 10 is tensioned. When the driving shaft 21 rotates, the driving shaft 21 and the driven shaft 22 can drive the filter 10 to rotate.

[0043] The driving mechanism 30 is connected to the driving shaft 21, and is used to drive the driving shaft 21 to rotate, so as to cooperate with the driven shaft 22 to drive the filter 10 to rotate. The driving mechanism 30 is used to provide power, and the output end of the driving mechanism 30 is connected to the driving shaft 21 in a transmission manner. For example, the output shaft of the driving mechanism 30 is connected to the driving shaft 21 through a coupling. When the driving mechanism 30 is working, the driving mechanism 30 can drive the driving shaft 21 to rotate, and the rotation of the driving shaft 21 drives the filter 10 to rotate.

[0044] The wind pressure detection assembly 40 is used to detect the air pressure difference information between the air inlet side and the air outlet side of the filter 10. The wind pressure detection assembly 40 includes two detection units (such as sampling tubes), and the two detection units are respectively located at the air inlet side and the air outlet side of the filter 10. For example, the two detection units are located at the air inlet side and the air outlet side of the part of the filter 10 that closes the fresh air inlet.

[0045] The cleaning mechanism 50 is used to clean the surface of the filter 10. The cleaning mechanism 50 may be a fixed structure; or, the cleaning mechanism 50 may be a movable structure, for example, the cleaning mechanism 50 is connected to a driving component and moves under the drive of the driving component to clean the filter. When the filter 10 rotates following the driving shaft 21, the cleaning mechanism 50 can clean the filter 10 to remove debris attached to the surface of the filter 10. For example, the cleaning mechanism 50 may include a brush or a roller brush.

[0046] The control system 60 is electrically connected to the wind pressure detection component 40, the drive mechanism 30 and the cleaning mechanism 50. The control system 60 can be connected to the electrical components (such as the wind pressure detection component 40, the drive mechanism 30, etc.) through a cable, or the control system 60 can also be connected to the electrical components wirelessly (such as WiFi, Bluetooth). The control system 60 may include a controller, such as a PLC control, an intermediate relay, etc.

[0047] The control system 60 is used to receive the air pressure difference information fed back by the wind pressure detection component 40 .

[0048] The control system 60 is used to control the operation of the driving mechanism 30 to drive the driving shaft 21 to rotate. After receiving the air pressure difference information fed back by the wind pressure detection component 40 (obtaining the air pressure difference between the air inlet side and the air outlet side), the control system 60 compares it with the preset air pressure difference. If the air pressure difference information fed back by the wind pressure detection component 40 is greater than the preset air pressure difference information, it indicates that there are more debris attached to the filter 10, and the filter 10 needs to be cleaned. At this time, the control system 60 controls the driving mechanism 30 to work, and the driving mechanism 30 drives the driving shaft 21 to rotate, thereby driving the filter 10 to rotate. While the filter 10 rotates, the cleaning mechanism 50 cleans the filter 10, and the clean part of the filter 10 located on the inside of the fresh air inlet rotates to the fresh air inlet, the part of the filter 10 with debris attached leaves the fresh air inlet and is cleaned by the cleaning mechanism 50, and the cleaned part of the filter 10 moves to the inside of the fresh air inlet. According to this cycle, the filter device 100 of the present application can realize automatic cleaning of the filter 10, meet cleaning requirements, and reduce labor costs.

[0049] Please refer to Figure 1 and Figure 2According to some embodiments of the present application, the driven shaft 22 includes a first driven shaft 221 and a second driven shaft 222. The driving shaft 21, the first driven shaft 221 and the second driven shaft 222 are arranged in a triangle. The first driven shaft 221 is located above the driving shaft 21 and the second driven shaft 222. The second driven shaft 222 is closer to the inner side of the fresh air inlet relative to the driving shaft 21.

[0050] The inner side of the fresh air inlet refers to the inner side of the accommodating chamber. The fresh air inlet is arranged on the wall of the accommodating chamber. A part of the filter screen blocks the fresh air inlet. The first driven shaft 221 and the driving shaft 21 can be located at the upper and lower ends of the fresh air inlet. The second driven shaft 222 is located on the side of the driving shaft 21 facing the inside of the accommodating chamber.

[0051] The driving shaft 21 and the second driven shaft 222 are arranged at intervals along the first direction X, and the first direction X may be parallel to the horizontal direction, or the angle between the first direction X and the horizontal direction is less than 5°. In some embodiments, along the first direction X, the projection of the driving shaft 21 may at least partially overlap with the projection of the second driven shaft 222.

[0052] The driving shaft 21 and the first driven shaft 221 may be arranged along the vertical direction Z. In some embodiments, along the vertical direction Z, the projection of the first driven shaft 221 may overlap with the projection of the driving shaft 21 .

[0053] The first driven shaft 221 and the driving shaft 21 may be located at two ends of the fresh air inlet in the vertical direction Z, respectively, so that the portion of the filter 10 located between the first driven shaft 221 and the driving shaft 21 can block the fresh air inlet.

[0054] In the above solution, the driving shaft 21 , the first driven shaft 221 and the second driven shaft 222 are arranged in a triangle shape, which has a simple structure and is convenient for cleaning the filter screen 10 .

[0055] Please refer to Figure 1 and Figure 2 According to some embodiments of the present application, the filter 10 includes a first area 11, a second area 12 and a third area 13. Along the circumference of the filter 10, the first area 11, the second area 12 and the third area 13 are arranged in sequence, the first area 11 is located between the first driven shaft 221 and the driving shaft 21, the second area 12 is located between the driving shaft 21 and the second driven shaft 222, and the third area 13 is located between the second driven shaft 222 and the first driven shaft 221. The first area 11 is used to block the fresh air inlet, the second area 12 and the third area 13 are arranged on the inner side of the fresh air inlet, and the cleaning mechanism 50 is arranged corresponding to the second area 12.

[0056] The first area 11, the second area 12 and the third area 13 are arranged around the circumference of the filter 10. When the filter 10 rotates, the part of the filter 10 located in the first area 11 moves toward the second area 12, the part of the filter 10 located in the second area 12 moves toward the third area 13, and the part of the filter 10 located in the third area 13 moves toward the first area 11.

[0057] The first area 11 may be an area of ​​the filter 10 for shielding the fresh air inlet, the second area 12 may be a cleaning area of ​​the filter 10, and the third area 13 may be a standby area of ​​the filter 10. The filter 10 in the first area 11 filters the air entering the fresh air inlet; the filter 10 in the second area 12 is cleaned by the cleaning mechanism 50; the filter 10 in the third area 13 has a higher cleanliness level, so that it can move to the first area 11 after the filter 10 rotates.

[0058] In the above scheme, the first area 11 is located at the fresh air inlet and is used to block the fresh air inlet; the cleaning mechanism 50 is arranged corresponding to the second area 12, so that when the part of the filter 10 in the first area 11 rotates to the second area 12, the cleaning mechanism 50 cleans the filter 10 to reduce the impact of debris on the fresh air inlet.

[0059] In some other embodiments, the driven shaft 22 may further include a third driven shaft, which may be located above the driving shaft 21 and the second driven shaft 222, and the third driven shaft and the first driven shaft 221 are spaced apart in the first direction X. Along the circumference of the filter screen 10, the driving shaft 21, the second driven shaft 222, the third driven shaft and the first driven shaft 221 are spaced apart in sequence, so that the driving shaft 21, the second driven shaft 222, the third driven shaft and the first driven shaft 221 are distributed in a quadrilateral. The cleaning mechanism 50 may be disposed between the driving shaft 21 and the second driven shaft 222, and between the second driven shaft 222 and the third driven shaft, so as to clean the portion of the filter screen 10 between the driving shaft 21 and the second driven shaft 222, and the portion of the filter screen 10 between the second driven shaft 222 and the third driven shaft.

[0060] Please refer to Figure 1 and Figure 2 According to some embodiments of the present application, the cleaning mechanism 50 includes a plurality of cleaning brushes 51 , and the plurality of cleaning brushes 51 are arranged at intervals along the circumference of the filter screen 10 , and the cleaning brushes 51 are in contact with the surface of the filter screen 10 .

[0061] In some embodiments, in addition to being located below the second area of ​​the filter, the cleaning brush 51 may also be located at the intersection of the first area and the second area of ​​the filter.

[0062] In the above scheme, a plurality of cleaning brushes 51 are arranged at intervals along the circumference of the filter 10 to clean the filter 10 at multiple positions. The cleaning brushes 51 are in contact with the surface of the filter 10, and when the filter 10 rotates, the cleaning brushes 51 can remove debris attached to the surface of the filter 10.

[0063] Please refer to Figure 1 and Figure 2 According to some embodiments of the present application, the extension direction of the cleaning brush 51 is set at an acute angle to the moving direction of the filter 10.

[0064] The extending direction of the cleaning brush 51 may be the length direction of the bristles of the cleaning brush 51 .

[0065] The cleaning brush 51 is in contact with the filter screen 10, and the extending direction of the cleaning brush 51 is set at an acute angle to the moving direction of the filter screen 10, for example, Figure 2 In the figure, the moving direction of the filter screen 10 is parallel to the X direction, and the angle between the extending direction of the cleaning brush 51 and the moving direction of the filter screen 10 is θ.

[0066] When the filter 10 moves, since the extension direction of the cleaning brush 51 is set at an acute angle to the moving direction of the filter 10, the cleaning brush 51 contacts the filter 10, so that the cleaning brush 51 can easily sweep away the debris attached to the filter 10, and the bristles of the cleaning brush 51 are not easy to affect the movement of the filter 10.

[0067] In the above scheme, the extension direction of the cleaning brush 51 is set at an acute angle to the moving direction of the filter screen 10, so that the cleaning brush 51 can clean the filter screen 10 when the filter screen 10 moves, thereby reducing the interference between the cleaning brush 51 and the filter screen 10.

[0069] The storage box 70 has an opening, and the opening is located at the top of the storage box 70, so that the storage box 70 can accommodate the filter 10 and the cleaning mechanism 50, and store sundries.

[0070] The lower end of the first area 11 and the lower end of the third area 13 may be located in the storage box 70 , so that the entire second portion is located in the storage box 70 .

[0071] The cleaning mechanism 50 is located in the storage box 70 to facilitate cleaning of the second area 12 and to facilitate storing the cleaned debris in the storage box 70 .

[0072] In the above scheme, the second area 12, a part of the first area 11 and a part of the third area 13 are located in the storage box 70, the cleaning mechanism 50 is arranged in the storage box 70, and the cleaning mechanism 50 corresponds to the second area 12. After the cleaning mechanism 50 cleans the filter 10, the debris can be stored in the storage box 70, thereby reducing the pollution of the debris to the environment.

[0073] Please refer to Figure 1 According to some embodiments of the present application, the filter device 100 also includes a dust suction component 80, which includes a negative pressure providing component 81 and a storage container 82.

One sampling tube is used to collect the air pressure on the air inlet side of the filter 10, and the other sampling tube is used to collect the air pressure on the air outlet side of the filter 10. The air pressure signals collected by the two sampling tubes are sent to the control system 60. For example, the air pressure on the air inlet side of the filter 10 is P1, the air pressure on the air outlet side of the filter 10 is P2, and the pressure difference ΔP is P1-P2. The pressure differential switch is electrically connected to the control system 60 and sends an air pressure differential signal to the control system 60. If ΔP is greater than the preset air pressure differential, the signal fed back by the air pressure switch to the control system 60 will cause the control system 60 to control the drive mechanism 30 to work.

[0080] The variable speed drive motor 31 may be a 220V electric drive motor.

[0081] The intermediate relay is electrically connected to the pressure difference switch and the variable speed drive motor 31. After receiving the signal from the pressure difference switch, if the pressure difference △P is greater than the preset air pressure difference, the intermediate relay controls the variable speed drive motor 31 to work, and the variable speed drive motor 31 drives the driving shaft 21 to rotate, thereby causing the filter 10 to rotate.

[0082] In the above scheme, the pressure difference switch is used to detect the air pressure difference between the air inlet side and the air outlet side of the filter 10; the variable speed drive motor 31 can adjust the rotation speed according to demand to change the rotation speed of the filter 10 to meet the cleaning requirements; the intermediate relay can drive the variable speed drive motor 31 to work according to the air pressure difference feedback from the pressure difference switch to clean the filter 10.

[0083] Please refer to Figure 1 According to some embodiments of the present application, first blocking members 211 are respectively provided at both ends of the driving shaft 21, and the filter 10 is provided between the two first blocking members 211; second blocking members 223 are respectively provided at both ends of the driven shaft 22, and the filter 10 is provided between the two second blocking members 223.

[0084] The first blocking member 211 may be a blocking member sleeved on the driving shaft 21, and the first blocking member 211 may be connected to the driving shaft 21 via a flat key, or the first blocking member 211 may have an interference fit with the driving shaft 21, or the first blocking member 211 may be welded to the driving shaft 21, or the first blocking member 211 may be threadedly connected to the driving shaft 21.

[0085] The second blocking member 223 can be a blocking member sleeved on the driven shaft 22. The second blocking member 223 can be connected to the driven shaft 22 via a flat key, or the second blocking member 223 can be interference fit with the driven shaft 22, or the second blocking member 223 can be welded to the driven shaft 22, or the second blocking member 223 can be threadedly connected to the driven shaft 22.

[0086] In the above solution, the provision of the first blocking member 211 can prevent the filter screen 10 from being separated from the driving shaft 21 ; the provision of the second blocking member 223 can prevent the filter screen 10 from being separated from the driven shaft 22 .

[0089] The edge of the filter 10 can slide with the wall of the accommodating chamber (which can be a concrete wall, a container wall, a steel profile wall, etc.) to block the fresh air inlet and prevent debris from entering the accommodating chamber from the area between the filter and the wall where the fresh air inlet is opened.

[0090] According to the data center of the embodiment of the present application, the filter 10 can filter out debris at the fresh air inlet, reducing the impact of the debris on the fresh air system or the air conditioning system.
