[0003] The present application relates to the field of battery technology, and in particular to a filter. Background Art

[0004] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the sustainable development of the automotive industry. For electric vehicles, battery technology is a key factor in their development.

[0005] During the battery manufacturing process, filters are required to filter the slurry being transported. How to facilitate the discharge of slurry from the filter is a key issue for filters.

[0006] Summary of the Invention

[0007] The present application aims to solve at least one of the technical problems in the background art. To this end, one purpose of the present application is to provide a filter to alleviate, mitigate or eliminate the problems in the related art.

[0008] An embodiment of the first aspect of the present application provides a filter, comprising: a shell, with a discharge port provided at the bottom of the shell; and a filter assembly, located inside the shell and connected to the shell, the filter assembly comprising at least one filter element, wherein at least one filter element each has a connection port provided near the discharge port, and at least one filter element discharges the filtered liquid from the discharge port through its respective connection port.

[0009] In the technical solution of the embodiment of the present application, the discharge port is set at the bottom of the shell, and the connection port of the filter element, i.e. the outlet, is close to the discharge port at the bottom of the shell, so that the filtered liquid (for example, slurry) inside the filter element flows to the discharge port due to gravity and can be completely discharged from the filter, thereby reducing slurry loss and reducing the risk of slurry that cannot be emptied agglomerating in the filter.

[0010] In some embodiments, the filter assembly further comprises a first mounting member disposed proximate the discharge port and connected to the housing, the first mounting member including at least one mounting hole for receiving at least one filter element. Inserting the filter element into the first mounting member provides greater stability and improves filtering performance.

[0011] In some embodiments, the filter assembly further includes: a second mounting member, the second mounting member including at least one limiting hole for defining an end portion of at least one filter element opposite the first mounting member; and a connecting member connecting the first mounting member to the second mounting member. When the filter element is inserted into the first mounting member, the second mounting member is used to limit the position of the filter element, and the first mounting member and the second mounting member are connected via the connecting member, so that the filter element is confined between the first mounting member and the second mounting member, thereby improving the stability of the filter element and the filtering effect.

[0012] In some embodiments, the housing further includes a third mounting member extending inwardly from an inner wall of the housing, and the first mounting member abuts against and is detachably connected to the third mounting member. The first and third mounting members are detachably connected, so that when the filter assembly is in use, the filter assembly is connected to the housing to increase its stability, and the filter assembly can be removed when the filter assembly needs to be replaced or cleaned, facilitating maintenance.

[0013] In some embodiments, the filter assembly further includes a discharge assembly for communicating with a connection port of at least one filter element. The discharge assembly is connected to the housing and extends from the first mounting member through the discharge port to the exterior of the housing. The discharge assembly directs filtered liquid (e.g., slurry) out of the filter, thereby separating unfiltered liquid in the housing from filtered liquid that has passed through the filter element via the discharge assembly, facilitating the discharge of filtered liquid and improving filtration efficiency.

[0014] In some embodiments, the discharge assembly includes a discharge tray mounted on the first mounting member and connected to the connection port of at least one filter element, and a discharge conduit connected to the discharge tray, wherein the discharge conduit extends through the discharge port to the exterior of the housing. The discharge tray collects filtered liquid and then discharges the filtered liquid from the filter through the discharge conduit, thereby separating unfiltered liquid in the housing from filtered liquid that has passed through the filter element via the discharge assembly, facilitating the discharge of filtered liquid and improving filtration efficiency.

[0015] In some embodiments, the housing further includes a support member extending from the inner wall of the housing toward the discharge pipe for supporting the discharge pipe. The support member is provided inside the housing to support the discharge pipe, making the discharge pipe more stable and reducing the risk of slurry loss due to shaking of the discharge pipe.

[0016] In some embodiments, the housing includes an upper housing and a lower housing that are detachably connected to each other, and the upper housing and the lower housing are spliced ​​together to enclose the filter assembly. Providing the housing with a separable upper and lower housing facilitates the removal of components such as the first mounting member, thereby facilitating comprehensive maintenance of the filter.

[0017] In some embodiments, the housing further comprises a feed port, a discharge port located at the bottom of the lower housing, and a feed port located on the peripheral sidewall of the lower housing. Positioning the discharge port at the bottom of the lower housing and the feed port on the peripheral sidewall of the lower housing facilitates the complete discharge of filtered liquid from the filter under the action of gravity. Furthermore, liquid can enter through the peripheral sidewall of the lower housing and accumulate therein, overflowing the filter element and entering the filter element, thereby enabling liquid that enters first to enter the filter element for filtration.

[0018] In some embodiments, the filter further comprises an end cap located at an end of the housing opposite the discharge port, the end cap being configured to form a closed chamber with the housing for containing the liquid to be filtered. By forming a closed chamber with the housing, the risk of the liquid being contaminated by impurities in the environment is reduced.

[0019] In some embodiments, the housing and the end cap are detachably connected. When the filter assembly needs to be maintained, the housing and the end cap can be disassembled to facilitate operations such as replacing or cleaning the filter assembly.

[0020] In some embodiments, a drain port is further provided at the bottom of the housing for draining the liquid to be filtered in the housing. The drain port is provided at the bottom of the housing so that the liquid that has not passed through the filter element can be drained from the drain port to empty the filter.

[0021] In some embodiments, the filter assembly includes a handle located on a side of at least one filter element opposite the connection port. The handle is provided on the side of the filter element not provided with the connection port, so that the filter element can be lifted out of the filter element for easy maintenance when the filter element needs to be replaced or cleaned.

[0022] In some embodiments, the housing further comprises a movable bracket to enable the filter to be movable. By providing the movable bracket, the filter can be moved as a whole, so that the filter can be used in different scenarios.

[0036] Currently, market developments indicate that power batteries are becoming increasingly widely used. Power batteries are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0037] During the battery production process, a filter is required to filter the slurry being transported. After the slurry enters the filter from the feed port, it is filtered through the filter element to block the impurities in the slurry. The filtered slurry is then discharged from the filter from the discharge port.

[0038] Over time, the filter retains more impurities, causing the filter element to clog and affect filtration effectiveness. When the filter element fails to meet filtration requirements, it must be cleaned or replaced before continued use. In some cases, the filter's discharge port is often located above the filter element, with the filter outlet facing the discharge port. The slurry enters the filter from the lower feed port, enters the filter element, and after being filtered, is discharged from the upper discharge port. Due to the high position of the discharge port, the slurry cannot be completely emptied, and some slurry will remain inside the filter element. Over time, this retained slurry will agglomerate within the filter element, affecting filtration effectiveness and making filter element maintenance difficult.

[0039] Based on the above considerations, in order to solve the problem that the slurry inside the filter cannot be completely emptied, resulting in difficulty in filter element maintenance, a filter is designed. By setting the discharge port at the bottom and inverting the filter element, the filtered slurry can be completely discharged under the action of gravity, emptying the filter, reducing slurry loss, reducing the risk of caking of the slurry that has not been emptied in the filter, and reducing the impact on the filter element.

[0040] The filter disclosed in the embodiments of the present application can be used, but is not limited to, in the production process of power batteries for vehicles, ships, aircraft, etc. Using the filter disclosed in the present application is beneficial to reducing the retention of slurry in the filter and improving the maintenance of the filter element.

[0041] The present invention provides a filter 100. Referring to FIG. 1 , the filter 100 includes:

[0042] The housing 110 is provided with a discharge port 113 at the bottom of the housing 110;

[0043] The filter assembly 120 is located inside the housing 110 and connected to the housing 110. The filter assembly 120 includes at least one filter element 121.

[0044] The at least one filter element 121 has a connection port 1211 disposed close to the discharge port 113 , and the at least one filter element 121 discharges the filtered liquid from the discharge port 113 through the connection port 1211 .

[0045] As shown in Figure 1, the filter 100 includes a shell 110 and a filter assembly 120 located inside the shell. A discharge port 113 is set at the bottom of the shell 110. The filter assembly 120 includes at least one filter element 121, and the connection port 1211 of the filter element 121 is close to the discharge port 113. The connection port of the filter element is used to discharge the liquid filtered by the filter element out of the filter element. In some examples, the connection port of the filter element can be directly connected to the discharge port to discharge the filtered liquid out of the filter. Alternatively, the connection port of the filter element can also be connected to the discharge port through, for example, a discharge assembly. The liquid to be filtered enters the interior of the filter element 121 from the outside to achieve the filtering function, and the impurities in the liquid are blocked outside the filter element 121. The filtered liquid enters the interior of the filter element 121 and is discharged from the filter 100 at the discharge port 113 through the connection port 1211.

[0046] The discharge port is set at the bottom of the shell, and the connection port of the filter element, i.e. the outlet, is close to the discharge port at the bottom of the shell, so that the filtered liquid (e.g., slurry) inside the filter element flows to the discharge port due to gravity and can be completely discharged from the filter, reducing slurry loss and the risk of caking of slurry that has not been emptied in the filter.

[0047] The inverted filter element can also reduce the length of the filter element by 200 mm, making it lighter and easier to handle.

[0048] According to some embodiments of the present application, the filter assembly 120 further includes:

[0049] The first mounting member 122 is disposed near the discharge port 113 and connected to the housing 110 , and the first mounting member 122 includes at least one mounting hole 1221 , and the at least one mounting hole 1221 is used to insert the connection port 1211 of at least one filter element 121 .

[0050] In some embodiments, filter element 121 is a detachable filter element that can be removed from filter assembly 120 for maintenance. First mounting member 122 can be used to position filter element 121 to provide greater stability. The shape of first mounting member 122 can be designed based on the filter housing and filter assembly, such as a plate-shaped structure, a block-shaped structure, or a barrel-shaped structure, although this disclosure is not limited thereto.

[0051] In the example shown in FIG1 , the first mounting member 122 is a plate-shaped structure, and mounting holes 1221 are provided on the plate. The number of mounting holes can be determined according to the number of filter elements to be used.

[0052] In some embodiments, the size of the mounting hole 1221 may be greater than or equal to the size of the connecting port 1211 of the filter element 121 , so that the connecting port 1211 of the filter element 121 can be inserted into the mounting hole 1221 .

[0053] In some embodiments, a first sealing ring 1281 is provided between the connection port 1211 and the mounting hole 1221 of the filter element 121 to improve the sealing performance and reduce the risk of slurry leakage.

[0054] Inserting the filter element on the first mounting piece makes the filter element more stable and can improve the filtering effect.

[0055] According to some embodiments of the present application, the filter assembly 120 further includes:

[0056] A second mounting member 123, the second mounting member 123 including at least one limiting hole (not shown) for defining an end portion of the at least one filter element 121 opposite to the first mounting member 122;

[0057] The connecting member 124 connects the first mounting member 122 and the second mounting member 123 .

[0058] To further securely position the filter element 121 within the filter 100, a second mounting member 123 may be provided at the other end of the filter element 121, opposite the first mounting member 122. A retaining hole is provided on the second mounting member 123, and the other end of the filter element 121, opposite the first mounting member 122, is restrained within the retaining hole, thereby reducing the risk of the filter element 121 shaking. The shape of the second mounting member 123 can be designed based on the filter housing and filter assembly, and may, for example, be a plate-shaped, block-shaped, or barrel-shaped structure, although this disclosure is not limited thereto.

[0059] In the example shown in FIG1 , the second mounting member 123 is a plate-like structure, and limiting holes are provided on the plate. The number of the limiting holes can be determined according to the number of filter elements to be used.

[0060] In some embodiments, the size of the limiting hole can be greater than or equal to the size of the filter element 121 to limit the filter element 121. Alternatively, the size of the limiting hole can also be slightly smaller than the size of the filter element to form an interference fit with the filter element, thereby increasing the stability of the filter element.

[0061] In some embodiments, a connector 124 can be used to connect the first mounting member 122 to the second mounting member 123 to confine the filter element 121 between the first mounting member 122 and the second mounting member 123, thereby improving the stability of the filter element. The connection method can be a bolt connection, a snap connection, etc., which is not limited in this disclosure.

[0062] In the example shown in FIG1 , a threaded hole corresponding to the connecting member 124 is provided on the first mounting member 122, and a through hole corresponding to the connecting member 124 is provided on the second mounting member 123. The connecting member 124 passes through the through hole in the second mounting member 123, is threadedly connected to the threaded hole in the first mounting member 122, and is connected to the second mounting member 123 using a bolt.

[0063] When the filter element assembled by the above structure is maintained or replaced, it is only necessary to remove the second mounting member 123 and then pull out the filter element, so as to facilitate the removal of the filter element. In this way, the filter element will not be bumped during the maintenance process and no metal particles will be generated.

[0064] When the filter element is inserted into the first mounting member, the second mounting member is used to limit the filter element, and the first mounting member and the second mounting member are connected by a connecting member so that the filter element is confined between the first mounting member and the second mounting member, thereby improving the stability of the filter element and the filtering effect.

[0065] According to some embodiments of the present application, the housing 110 further includes a third mounting member 114 extending inward from an inner wall of the housing 110 , and the first mounting member 122 abuts against the third mounting member 114 and is detachably connected to the third mounting member 114 .

[0066] A third mounting member 114 extending inwardly is provided on the inner wall of the housing 110 to detachably connect the first mounting member 122 of the filter assembly 120 thereto. Connection methods such as threaded connection, snap connection, and clamping connection may be used, and this disclosure is not limited thereto. Alternatively, the third mounting member may be detachably connected to the first and second mounting members.

[0067] The first mounting member and the third mounting member are arranged to be detachably connected, so that when the filter assembly is in use, the filter assembly is connected to the shell to increase the stability of the filter assembly. When the filter assembly needs to be replaced or cleaned, the filter assembly can be removed for easy maintenance.

[0068] According to some embodiments of the present application, the filter assembly 120 also includes a discharge assembly 125 for communicating with a connection port 1211 of at least one filter element 121 . The discharge assembly 125 is connected to the shell 110 and extends from the first mounting member 122 through the discharge port 113 to the outside of the shell 110 .

[0069] The discharge assembly 125 is in communication with the connection port 1211 of the filter element 121 , and can collect the liquid filtered by the filter element and transport the filtered liquid to the outside of the filter 100 .

[0070] In some examples, the discharge assembly may be fixedly connected to the housing or detachably connected to the housing.

[0071] In this way, the unfiltered liquid in the housing can be separated from the filtered liquid passing through the filter element via the discharge assembly, and the liquid filtered by the filter element is guided to the discharge port through the additional discharge assembly instead of through the housing, thereby not only promoting the discharge of the filtered liquid to improve the filtration efficiency, but also improving the sealing performance of the bottom of the filter element, especially that located in the detachable housing.

[0072] According to some embodiments of the present application, the discharge assembly 125 includes a discharge tray 1251 that is mounted on the first mounting member 122 to communicate with the connection port 1211 of at least one filter element 121, and a discharge pipe 1252 that is connected to the discharge tray 1251, wherein the discharge pipe 1252 extends through the discharge port 113 to the outside of the shell 110.

[0073] The discharge assembly 125 includes a discharge tray 1251 for collecting the liquid filtered by the filter element 121 and a discharge pipe 1252 for discharging the filtered liquid out of the filter 100. The discharge tray can be configured to be funnel-shaped or hemispherical.

[0074] In some embodiments, a second sealing ring 1282 is installed between the discharge tray 1251 and the discharge pipe 1252 to reduce the risk of liquid leakage.

[0075] The filtered slurry is collected using a discharge tray and then discharged from the filter through a discharge pipe, thereby separating the unfiltered liquid in the shell from the filtered liquid passing through the filter element through the discharge assembly, promoting the discharge of the filtered liquid to improve the filtration efficiency.

[0076] Alternatively, the discharge assembly may also only include at least one discharge pipe respectively connected to the connection port of at least one filter element. Alternatively, the discharge assembly may also only include a discharge tray connected to the discharge port.

[0077] According to some embodiments of the present application, the shell 110 further includes a support member 126 extending from the inner wall of the shell 110 toward the discharge pipe 1252 for supporting the discharge pipe 1252 .

[0078] In order to reduce the shaking of the discharge pipe 1252 inside the filter, a support member 126 is provided on the inner wall of the shell 110 facing the discharge pipe 1252 to provide support for the discharge pipe 1252.

[0079] A support member is provided inside the shell to support the discharge pipe, making the discharge pipe more stable and reducing the risk of slurry loss due to shaking of the discharge pipe.

[0080] According to some embodiments of the present application, the housing 110 includes an upper housing 111 and a lower housing 112 that are detachably connected to each other. The upper housing 111 and the lower housing 112 are spliced ​​together to surround the filter assembly 120 .

[0081] When maintenance is required on the filter assembly 120, the housing 110 is configured to comprise an upper housing 111 and a lower housing 112 for greater ease of operation. The filter assembly 120 can be connected to either the upper housing 111 or the lower housing 112. In the example shown in FIG1 , the filter assembly 120 can be connected to the lower housing 112. To facilitate maintenance, the upper and lower housings 111, 112, and the upper housing 111 can be removed, thereby facilitating easier operation of the filter assembly 120. In some embodiments, the filter assembly 120 can also be connected to the upper housing 111. To facilitate maintenance, the lower housing 112 can be removed, and maintenance operations such as cleaning or replacing the filter assembly 120 can then be performed.

[0082] The upper shell 111 and the lower shell 112 can be connected by threaded connection, lock connection, clamping connection and other connection methods, which are not limited in this disclosure. In the example shown in Figure 1, the upper shell 111 and the lower shell 112 can be connected by eye nuts.

[0083] Providing the housing as an upper housing and a lower housing that can be separated from each other can facilitate the removal of components such as the first mounting member, thereby facilitating comprehensive maintenance of the filter.

[0084] According to some embodiments of the present application, the shell 110 further includes a feed port 115 , the discharge port 113 is located at the bottom of the lower shell 112 , and the feed port 115 is located on the peripheral side wall of the lower shell 112 .

[0085] The filter 100 is further provided with a feed port 115 . The feed port 115 may be positioned higher than the discharge port 113 , and the feed port 115 may be provided on the peripheral side wall of the shell.

[0086] In the example shown in FIG1 , the discharge port 113 is provided at the bottom of the lower housing 112 to discharge the filtered liquid out of the filter. The feed port 115 is provided on the peripheral side wall of the lower housing 112 , higher than the discharge port 113 .

[0087] The discharge port is set at the bottom of the lower shell, and the feed port is set on the peripheral side wall of the lower shell. On the one hand, it is beneficial for the filtered liquid to be completely discharged from the filter under the action of gravity. On the other hand, it can realize that the liquid enters from the peripheral side wall of the lower shell and then accumulates continuously to overflow the filter element and enter the filter element, thereby prompting the liquid that enters first to enter the filter element for filtration first.

[0088] Alternatively, the feed port may also be provided on the upper shell.

[0089] According to some embodiments of the present application, the filter 100 further includes:

[0090] The end cover 131 is located at the end of the housing 110 opposite to the discharge port 113 . The end cover 131 is used to form a closed chamber with the housing 110 for accommodating the liquid to be filtered.

[0091] As shown in Figure 1, an end cap 131 is provided at the end of the housing 110 opposite to the discharge port 113. The end cap 131 and the housing 110 can form a closed chamber to accommodate the liquid to be filtered.

[0092] In some embodiments, the end cap 131 may be provided with a test instrument port 132 and an exhaust port 133. The test instrument port 132 can be used to accommodate various test instruments, such as a thermometer and a pressure gauge, to monitor the internal environment of the filter 100. The exhaust port 133 is used to discharge gas from the filter 100, thereby reducing safety hazards caused by excessive air pressure within the filter.

[0093] In some embodiments, the filter 100 further includes a rocker arm 141, and the housing 110 and the end cap 131 can be connected to both ends of the rocker arm 141. When the end cap 131 needs to be separated from the housing 110, the rocker arm 141 is used to lift the end cap 131 and move the end cap 131 to one side to expose the interior of the housing 110.

[0094] By using the end cap and the housing to form a closed chamber, the risk of the liquid being contaminated by impurities in the environment is reduced.

[0095] According to some embodiments of the present application, the housing 110 and the end cover 131 are detachably connected.

[0096] The housing 110 and the end cap 131 may be connected by threaded connection, snap connection, clamping connection, etc., which is not limited in the present disclosure. In the example shown in FIG1 , the housing 110 and the end cap 131 may be connected by an eye nut.

[0097] When the filter assembly needs to be maintained, the shell and the end cover can be disassembled to facilitate operations such as replacing or cleaning the filter assembly.

[0098] According to some embodiments of the present application, a drain port 116 is further provided at the bottom of the housing 110 , and the drain port 116 is used to discharge the liquid to be filtered in the housing 110 .

[0099] As shown in FIG1 , a drain port 116 is provided at the bottom of the housing 110 and is equipped with a corresponding drain valve 117. The drain valve 117 is closed when the filter 100 is filtering. When the liquid to be filtered (specifically, the liquid not filtered by the filter element) needs to be discharged, the drain valve 117 is opened to allow the liquid to flow out of the filter 100.

The inlet is located on the sidewall of the lower housing 112, and the discharge port 113 is located at the bottom of the lower housing 112. The filter assembly 120 also includes a discharge tray 1251 and a discharge pipe 1252. The discharge tray 1251 is used to collect the filtered slurry. The discharge pipe 1252 extends through the discharge port 113 to the exterior of the lower housing 112 and is used to discharge the filtered slurry out of the filter. A sealing ring is provided between the discharge tray 1251 and the discharge pipe 1252 to improve sealing performance. The lower housing 112 is also equipped with a support member 126, which is welded to the lower housing 112 and the discharge pipe 1252 to support the discharge pipe 1252.

[0113] The lower housing 112 is further provided with a drain port 116 . When it is necessary to empty the unfiltered slurry, the drain valve 117 is opened to discharge the unfiltered slurry from the filter 100 .

[0114] When maintenance is required on filter element 121, the eye nut between end cap 131 and upper housing 111 can be removed. End cap 131 can then be lifted and moved to one side using rocker arm 141 to expose the interior of the housing. The bolts attached to second mounting member 123 on connector 124 can be removed. Second mounting member 123 can then be removed. The filter element 121 requiring maintenance can then be lifted out using handle 127 for maintenance.
