[0039] Reference below Figure 1-Figure 7 , describing a filtering device 100 according to an embodiment of the present utility model.

[0040] like Figures 1 to 4 As shown, a filtering device 100 according to an embodiment of the utility model includes a housing 10 and a filter element 20 .

[0041] The shell 10 includes a first shell portion 101 and a second shell portion 102 that are cross-connected; wherein the first shell portion 101 has a first axial direction O1, and a water inlet 101a is provided at one end located at the first axial direction O1, and on a first plane perpendicular to the first axial direction O1, the area of ​​the projection surface of the contour surrounded by the inner edge of the water inlet 101a on the first plane is smaller than the area of ​​the projection surface of the contour surrounded by the inner edge of the first shell portion 101 on the first plane; the second shell portion 102 has a second axial direction O2, and a water outlet 102a is provided at one end away from the first shell portion 101, and on a second plane perpendicular to the second axial direction O2, the area of ​​the projection surface of the contour surrounded by the inner edge of the water outlet 102a on the second plane is smaller than the area of ​​the projection surface of the contour surrounded by the inner edge of the second shell portion 102 on the second plane.

[0042] The first axial direction O1 may refer to the centerline direction of the first shell 101. The shape of the first shell 101 may include but is not limited to a cylindrical shape and a prism shape. For example, when the first shell 101 is a round tube, the first axial direction O1 is the axis direction of the first shell 101; when the first shell 101 is a square tube, the first axial direction O1 is the centerline direction of the first shell 101. Similarly, the second axial direction O2 is the centerline direction of the second shell 102. The shape of the second shell 102 may be but is not limited to a cylindrical shape and a prism shape. The shapes of the second shell 102 and the first shell 101 may be the same or different.

[0043] Optionally, the shapes of the water inlet 101a and the water outlet 102a may be, but are not limited to, circular, square, and the like.

[0044] On the first plane perpendicular to the first axial direction O1, the projection area of ​​the contour enclosed by the inner edge of the water inlet 101a on the first plane is smaller than the projection area of ​​the contour enclosed by the inner edge of the first shell 101 on the first plane, which may mean that the cross-sectional area of ​​water when flowing through the water inlet 101a is smaller than the cross-sectional area when flowing through the first shell 101.

[0045] Exemplarily, when the first shell 101 is a round tube and the water inlet 101a is a round hole, it can be understood that the diameter of the water inlet 101a is smaller than the inner diameter of the first shell 101; when the first shell 101 is a square tube and the water inlet 101a is a square hole, it can be understood that the area of ​​the water inlet 101a is smaller than the cross-sectional area of ​​the first shell 101. Of course, the shapes of the first shell 101 and the water inlet 101a can also be different. For example, if the first shell 101 is a round tube and the water inlet 101a is a square hole, it can be understood that the area of ​​the water inlet 101a is smaller than the cross-sectional area of ​​the first shell 101.

[0046] Similarly, on the second plane perpendicular to the second axial direction O2, the area of ​​the projection of the contour formed by the inner edge of the water outlet 102a on the second plane is smaller than the area of ​​the projection of the contour formed by the inner edge of the second shell 102 on the second plane, which can be understood as the cross-sectional area of ​​water flowing through the second shell 102 is larger than the cross-sectional area of ​​water flowing through the water outlet 102a. For details, please refer to the above explanation, which will not be repeated here.

[0047] The filter element 20 is disposed in the first shell 101 and extends along the first axial direction O1, and a gap 30 is provided between the circumferential side of the filter element 20 around the first axial direction O1 and the inner wall surface of the first shell 101. It can be understood that one end of the filter element 20 close to the water inlet 101a is abutted against the water inlet 101a, so that the incoming water can be filtered through the filter element 20.

[0048] In the above-mentioned filtering device 100, when water flows into the first shell 101 and the second shell 102 from the water inlet 101a, since on the first plane, the projection area of ​​the outline formed by the inner edge of the water inlet 101a on the first plane is smaller than the projection area of ​​the outline formed by the inner edge of the first shell 101 on the first plane, the pressure of water after entering the first shell 101 will decrease and the flow rate will decrease. Since friction resistance will be generated between water and the shell wall of the first shell 101, and the pipe diameter of the first shell 101 will be larger than that of the water inlet 101a, the friction resistance of the fluid per unit length can be reduced, thereby reducing the friction loss of the fluid in the first shell 101, thereby reducing the system flow resistance and improving energy efficiency.

[0049] Because on the second plane perpendicular to the second axial direction O2, the projection area of ​​the contour enclosed by the inner edge of the water outlet 102a on the second plane is smaller than the projection area of ​​the contour enclosed by the inner edge of the second shell 102 on the second plane, since the water flow from the water inlet 101a into the first shell 101 needs to be depressurized and decelerated, when the water flows out of the water outlet 102a from the second shell 102, it can play a role of increasing pressure and speeding up, which is conducive to making the pressure and flow rate of the water flow when flowing out of the water outlet 102a consistent with the pressure and flow rate of the water flow flowing into the water inlet 101a, so that the flow rate of the water at the water inlet 101a and the water outlet 102a can be consistent, reducing the impact on the water flow.

[0050] A gap 30 is provided between the circumferential side of the filter element 20 around the first axial direction O1 and the inner wall surface of the first shell 101. The gap 30 can provide a certain space between the filter element 20 and the first shell 101, making the replacement and maintenance of the filter element 20 more convenient and quick. The staff can easily remove the old filter element 20 and install the new filter element 20 without the difficulty of disassembly caused by the close installation of the filter element 20 and the first shell 101. Secondly, the gap 30 can also allow a part of the material passing through the filter element 20 to form a uniform layer of filter waste around the filter element 20, preventing the filter layer from being blocked or blocked prematurely, which is conducive to extending the service life of the filter element 20 and maintaining the high-efficiency filtering performance of the filter element 20.

[0051] It should also be noted that if Figure 7 As shown (the arrow in the figure indicates the direction of water flow), the filter device 100 can be applied in an energy storage device 1000. The energy storage device 1000 may include a first pipe 200 and a second pipe 300 that are cross-connected, the first pipe 200 is connected to the water inlet 101a, and the second pipe 300 is connected to the water outlet 102a. Since the first pipe 200 and the second pipe 300 are cross-connected, the filter device 100 has better adaptability and can reduce the impact on the water flow path.

[0052] According to the filter device 100 of the embodiment of the utility model, by adopting the shell 10 of the above-mentioned structure, the pressure can be reduced and the flow rate can be reduced when the water flows from the water inlet 101a into the first shell part 101, and the pressure and speed can be increased when the water flows out from the second shell part 102 to the water outlet 102a. This can not only reduce the system flow resistance of the filter device 100, but also make the flow rate of water flowing in and out consistent, which is beneficial to improving the working efficiency of the filter device 100.

[0053] In some embodiments of the present invention, the projection of the contour formed by the inner edges of the first shell portion 101 on the first plane and the projection of the contour formed by the inner edges of the second shell portion 102 on the second plane have the same shape and the same area.

[0054] It can be understood that if the first shell 101 is a round tube, the second shell 102 is also a round tube, and the inner diameters of the two are equal; if the first shell 101 is a square tube, the second shell 102 is also a square tube, and the cross-sectional areas of the two are equal.

[0055] By making the projection of the outline formed by the inner edge of the first shell portion 101 on the first plane and the projection of the outline formed by the inner edge of the second shell portion 102 on the second plane have the same shape and equal area, when the water flows from the first shell portion 101 to the second shell portion 102, the second shell portion 102 can play the same role as the first shell portion 101, reducing the pressure of the water flow from the water inlet 101a and reducing the flow rate, thereby further reducing the friction resistance formed by the water flow and the shell wall of the shell 10, further reducing the system flow resistance, and further improving the working efficiency of the filtering device 100.

[0056] In some embodiments of the present invention, Figures 1 to 4 As shown, the first shell portion 101 and the second shell portion 102 are round tubes.

[0057] In the above technical solution, the circular tube is one of the shapes with the most uniform strength under stress, and its circular cross-section can evenly distribute the pressure applied internally or externally, so that the first shell 101 and the second shell 102 have better anti-twisting and anti-deformation capabilities, reducing the possibility of deformation and rupture of the first shell 101 and the second shell 102.

[0058] Secondly, by setting the first shell 101 and the second shell 102 as a round tube, the circular cross-section can reduce the resistance loss when the fluid passes through the pipeline, provide a smoother fluid flow path, reduce the possibility of friction between the first shell 101 and the second shell 102, and help to further reduce the resistance loss during fluid transportation. Moreover, the first shell 101 and the second shell 102 with this shape are also convenient for manufacturing, installation and connection, which can reduce the difficulty of construction and improve construction efficiency. Moreover, compared with other shapes, the round tube can greatly reduce material waste and reduce costs.

[0059] In some embodiments of the present invention, the projection area of ​​the contour formed by the inner edges of the water inlet 101a on the first plane and the projection area of ​​the contour formed by the inner edges of the water outlet 102a on the second plane are equal.

[0060] It can be understood that the water inlet 101a and the water outlet 102a have the same shape and size. Exemplarily, the water inlet 101a and the water outlet 102a can be circles with the same diameter, or rectangles with the same length and width.

[0061] Since the projection surface of the outline formed by the inner edge of the first shell portion 101 on the first plane and the projection surface of the outline formed by the inner edge of the second shell portion 102 on the second plane are the same in shape and have the same area, on this basis, by setting the projection surface of the outline formed by the inner edge of the water inlet 101a on the first plane and the projection surface of the outline formed by the inner edge of the water outlet 102a on the second plane to be equal, the flow rate of water flowing in from the water inlet 101a and flowing out from the water outlet 102a can be made the same, which helps to reduce the impact on the water flow.

[0062] In some embodiments of the present invention, Figure 1 As shown, the water inlet 101a and the water outlet 102a are circular openings. By setting the water inlet 101a and the water outlet 102a as circular openings, it is convenient to connect the water inlet 101a and the water outlet 102a with external pipes, which can reduce the construction difficulty of the filter device 100 in the energy storage device 1000 and improve the construction efficiency.

[0063] In some embodiments of the present invention, Figures 1 to 7 As shown, a chuck 103 is provided at one end of the first shell 101 located in the first axial direction O1, and the water inlet 101a is arranged through the chuck 103. The chuck 103 is used to facilitate connection with external pipe fittings, thereby facilitating communication between the water inlet 101a and the external pipe fittings.

[0064] Optionally, a first threaded connector may be provided at one end of the first shell 101 located in the first axial direction O1, the water inlet 101a passes through the first threaded connector, and the first threaded connector is threadedly connected to an external pipe. Alternatively, the end of the first shell 101 located in the first axial direction O1 may also be welded to an external pipe. Optionally, the external pipe may refer to the first pipe 200 in the energy storage device 1000.

[0065] In some embodiments of the present invention, Figures 2 to 7 As shown, a flange 104 is provided at one end of the second shell 102 away from the first shell 101, and the water outlet 102a is provided through the flange 104. The flange 104 is conveniently connected to an external pipe, so that the water outlet 102a is conveniently connected to the external pipe. Optionally, the external pipe may refer to the second pipe 300 in the energy storage device 1000, and further, the pipe may also be a component such as an interface or pipeline of a water pump.

[0066] Optionally, a second threaded connector may be provided at one end of the second shell 102 away from the first shell 101, the water outlet 102a passes through the second threaded connector, and the second threaded connector is threadedly connected to an external pipe. Alternatively, the end of the second shell 102 away from the first shell 101 may also be welded to an external pipe. Optionally, the external pipe may refer to the second pipe 300 in the energy storage device 1000.

[0067] In some embodiments of the present invention, the projection area of ​​the filter element 20 on the first plane is larger than the projection area of ​​the water inlet 101a on the first plane. In other words, in this way, the water flow can pass through the filter element 20 after entering from the water inlet 101a, preventing the water flow from directly entering the gap 30 without filtering.

[0068] In some embodiments of the present invention, Figures 1 to 4 As shown, the other end of the first shell 101 located in the first axial direction O1 is provided with an inspection port 101b, and the filter device 100 includes a maintenance end cover 40 and a clamp assembly 50, the maintenance end cover 40 is covered on the inspection port 101b, and the clamp assembly 50 is fixedly connected between the maintenance end cover 40 and the first shell 101.

[0069] In the above technical solution, the maintenance end cover 40 and the first shell 101 can be easily installed or removed by the clamp assembly 50, which can improve the installation or removal efficiency. After the maintenance end cover 40 is quickly removed from the first shell 101 by the clamp assembly 50, the filter element 20 can be pulled out for replacement and maintenance, which is beneficial to the daily maintenance of the filter device 100 and prolongs the service life of the device.

[0070] Optionally, the clamp assembly 50 may include a clamp body and bolts, wherein the bolts are connected at both ends of the clamp body, and the diameter of the clamp body can be adjusted by loosening the bolts. For example, clockwise rotation of the bolt can reduce the diameter of the clamp body, wrapping the first shell 101 and the maintenance end cover 40 and fixing the two tightly, while counterclockwise rotation of the bolt can increase the diameter of the clamp body, thereby removing the maintenance end cover 40 from the first shell 101, thereby facilitating the removal of the maintenance end cover 40 from the first shell 101.

[0071] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, a first limiting portion 401 is provided at the end of the maintenance end cover 40 close to the first shell portion 101 , and the first limiting portion 401 is used to limit the displacement of the filter element 20 along the first axial direction O1 .

[0072] It can be understood that the first limiting portion 401 may include but is not limited to a limiting block, a limiting retaining ring, and the like.

[0073] In the above solution, the first limiter 401 can limit the displacement of the filter element 20 in the first shell 101 along the first axial direction O1, thereby improving the position accuracy of the filter element 20 in the first shell 101 and preventing the filter element 20 from being degraded or uneven due to positional displacement during operation. The first limiter 401 can also reduce the displacement or deformation of the filter element 20 due to vibration or external force during operation, thereby extending the service life of the filter element 20.

[0074] In some embodiments of the present invention, Figure 2 As shown, the filter device 100 includes an elastic member 60 , which is disposed between the first limiting portion 401 and the filter element 20 , and abuts against the first limiting portion 401 and the filter element 20 .

[0075] The elastic member 60 may include but is not limited to a rubber member and an elastic metal member.

[0076] In the above technical solution, when the maintenance end cover 40 is fixed on the first shell part 101 by the clamp assembly 50, the filter element 20 and the first limiting part 401 can squeeze the elastic member 60 during the process. The compression of the elastic member 60 can make the filter element 20 more firmly fixed in the first shell part 101, thereby improving the reliability of the filter element 20 during operation.

[0077] Optionally, the elastic member 60 may be a rubber ring. In this technical solution, the rubber ring has a simple structure, is easy to manufacture, and is also easy to install between the first limiting portion 401 and the filter element 20.

[0078] In some embodiments of the present invention, Figure 4 As shown, a second limiting portion 101 c is disposed in the first shell portion 101 , and the second limiting portion 101 c abuts against the filter element 20 .

[0079] The second limiting portion 101c may include but is not limited to a limiting block, a limiting retaining ring, and the like.

[0080] In the above solution, the second limiter 101c can limit the displacement of the filter element 20 in the first shell 101 along the first axial direction O1, thereby improving the position accuracy of the filter element 20 in the first shell 101 and preventing the filter element 20 from being degraded or uneven due to positional displacement during operation. The second limiter 101c can also reduce the displacement or deformation of the filter element 20 due to vibration or external force during operation, thereby extending the service life of the filter element 20.

[0081] In some embodiments of the present invention, Figure 2As shown, the filter device 100 includes a sealing ring 70, which is disposed between the maintenance end cover 40 and the first shell 101. In this technical solution, the sealing ring 70 can improve the sealing between the filter element 20 and the maintenance end cover 40, prevent leakage at the location of the maintenance end cover 40, and help improve the reliability of the filter device 100 and ensure its working efficiency.

[0082] In some embodiments of the present invention, Figure 5 As shown, the filter device 100 further includes a sewage discharge member 80 , which is disposed on the maintenance end cover 40 and close to the bottom of the filter element 20 . The sewage discharge member 80 is connected to the internal space of the first shell portion 101 .

[0083] The sewage discharge member 80 may refer to a flow path opening and closing member including but not limited to a valve, etc., and is used to discharge the impurities filtered by the filter element 20 from the first shell 101. The sewage discharge member 80 is normally kept closed. After the filter device 100 has worked for a period of time, the sewage discharge member 80 can be opened. At this time, the impurities filtered by the filter element 20 in the first shell 101 can be discharged from the first shell 101 through the sewage discharge member 80, which is conducive to the normal operation of the filter element 20.

[0084] In the above scheme, by setting the sewage discharge member 80, the filter device 100 can have a sewage discharge function, which is conducive to convenient and timely cleaning of dirt and extending the service life of the filter device 100. By setting the sewage discharge member 80 on the maintenance end cover 40, the sewage discharge member 80 can be first assembled on the maintenance end cover 40, and then the maintenance end cover 40 is assembled with the first shell 101. Since the volume of the maintenance end cover 40 is relatively small relative to the first shell 101, the difficulty of assembling the sewage discharge member 80 is reduced. Secondly, since the impurities filtered by the filter element 20 are mostly concentrated at the bottom of the filter element 20 under the action of its own gravity, the sewage discharge member 80 is arranged close to the bottom of the filter element 20, so that the sewage discharge effect of the impurities can be better, which is conducive to completely discharging the impurities during sewage discharge.

[0085] In some embodiments of the present invention, reference Figure 6 The filter device 100 further includes a sewage discharge member 80 , which is disposed at the bottom of the first shell 101 and is connected to the first shell 101 . The sewage discharge member 80 is located on a side of the filter element 20 away from the water inlet 101 a .

[0086] In the above technical solution, by providing the sewage discharge member 80, the filter device 100 can have a sewage discharge function, which is conducive to convenient and timely cleaning of debris and extending the service life of the filter device 100. Since the impurities filtered by the filter element 20 are mostly concentrated at the bottom of the filter element 20 under the action of its own gravity, the sewage discharge member 80 is arranged at the bottom of the first shell 101, so that when sewage is discharged, the impurities can be directly discharged along the sewage discharge member 80, which can further improve the effect of thoroughly discharging the impurities. The sewage discharge member 80 is located on the side of the filter element 20 away from the water inlet 101a, so that the sewage discharge member 80 can be located in the concentrated area of ​​​​the impurities, thereby achieving a better sewage discharge effect.

[0087] In some embodiments of the present invention, Figure 1 As shown, the first axial direction O1 is perpendicular to the second axial direction O2. That is, the first shell portion 101 and the second shell portion 102 are perpendicular to each other and connected, so the housing 10 is L-shaped or T-shaped, and the filter element 20 extends along the first axial direction O1, so the water flow can be filtered along the length direction of the filter element 20 and flow out from the second shell portion 102 on one side, thereby further reducing the flow resistance.

[0088] like Figure 7 As shown, an energy storage device 1000 according to an embodiment of the utility model includes: a first pipeline 200, a second pipeline 300 and a filter device 300. The first pipeline 200 and the second pipeline 300 are cross-connected. In the filter device 100, the water inlet 101a is connected to the first pipeline 200, and the water outlet 102a is connected to the second pipeline 300.

[0089] Since the first pipe 200 and the second pipe 300 are cross-connected, the filter device 100 has better adaptability and can reduce the impact on the water flow path. The first pipe 200 and the second pipe 300 can be arranged perpendicular to each other or at an angle.

[0090] The energy storage device 1000 according to the embodiment of the utility model can reduce the system flow resistance of the water flow by adopting the filtering device 100, has a relatively good filtering efficiency, is also conducive to adapting to pipeline installation, and has a relatively small impact on the water flow in the pipeline.
