Description

Technical Field

[0001] This application relates to the field of filter technology, and in particular to a UPE filter. Background Technology

[0002] UPE filter cartridges are typically installed inside a filter housing for fine filtration of liquids or gases. Their pleated structure helps improve filtration efficiency, and the required filtration precision can be achieved by adjusting the density of the pleats and the material of the filter paper.

[0003] When using a typical UPE filter cartridge to filter gas, depending on the environment, the gas may contain a large amount of impurities such as oil and dust. After prolonged filtration, the surface of the filter cartridge will be covered with a layer of impurities, such as oil or dust, which will affect the filtration effect. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a UPE filter element.

[0005] The UPE filter element provided in this application adopts the following technical solution: A UPE filter element includes a first connector, a second connector, a cleaning component, a receiving component, and an inner core. The first connector and the second connector are respectively connected to both ends of the inner core, and the outer diameters of the first connector and the second connector are both larger than the outer diameter of the inner core. The cleaning component is sleeved on the inner core and moves along the surface of the inner core. The inner wall of the cleaning component is provided with a cleaning brush to clean the surface of the inner core. The receiving component is provided on the first connector or the second connector, and the impurities cleaned out are received by the receiving component.

[0006] By adopting the above technical solution, after the filter element has been used for a long time, impurities will stick to its surface. Therefore, maintenance personnel can periodically pull the cleaning component to move it along the surface of the inner core and clean the impurities on the surface of the inner core. During the movement, the cleaning component will move the impurities to the receiving component, so that the impurities will fall into the receiving component for temporary collection. The first connecting component and the second connecting component restrict the position of the cleaning component, so that the cleaning component cannot leave the inner core, thereby facilitating the cleaning of impurities from the filter element.

[0007] Optionally, the first and second connectors have the same structure, both including a connecting cover and a fastening part; the connecting cover has a receiving interface for the receiving part to be embedded; the fastening part is connected to the connecting cover and is installed on the side of the connecting cover away from the end of the inner core; the cleaning part is detachably connected to the fastening part.

[0008] By adopting the above technical solution, the connecting caps corresponding to the first and second connecting parts respectively restrict both ends of the inner core, so that the cleaning part cannot be separated from the inner core. When the cleaning part does not need to be cleaned or after cleaning is completed, it can be fixed in position by the fastening part, so that the filter element will not be affected by the cleaning part during daily use.

[0009] Optionally, there are 2-4 receiving interfaces, and the number of receiving parts is the same, with each receiving part corresponding to one receiving interface.

[0010] By adopting the above technical solution, the connecting cover will not break when it is separated by multiple sockets, ensuring the stability of the connection between the connecting cover and the inner core. Then, the sockets are inserted into the sockets by the insertion action of the receiving parts. When multiple sockets are filled, multiple receiving parts form a complete ring structure.

[0011] Optionally, the receiving component adopts an arc-shaped groove with an inclined surface. The groove opening of the arc-shaped groove is larger than the receiving interface, and the bottom is smaller than the receiving interface, so that the groove of the receiving component is locked in the receiving interface.

[0012] By adopting the above technical solution, the receiving component can be locked onto the receiving interface by using an arc-shaped groove structure, thereby improving the efficiency of removing the receiving component from the receiving interface for replacement or cleaning.

[0013] Optionally, a plurality of guide posts are provided between the two connecting covers, and the plurality of guide posts are arranged around the inner core; the cleaning component is located within the guiding range of the plurality of guide posts and contacts the guide posts.

[0014] By adopting the above technical solution, the guiding effect of the guide column ensures that the inner wall of the cleaning component does not stick tightly to the inner core. All positions of the inner core are subjected to the average force of the cleaning component, preventing excessive force on the cleaning component at a certain position from damaging the inner core and improving the stability of use.

[0015] Optionally, the connecting cover has a separation port, the guide post extends outward through the separation port, and the extended portion has an external thread, and the threaded portion is screwed to the extended portion.

[0016] By adopting the above technical solution, the guide post is screwed into the connecting cover through the threaded part, so that the guide post is screwed tightly and cannot be detached. At the same time, the cleaning part is limited. When disassembly is required, the threaded part can be unscrewed to facilitate disassembly and assembly.

[0017] Optionally, the fastening part is a permanent magnet, the cleaning component contains magnetic material, and the cleaning component is magnetically connected to the fastening part.

[0018] By adopting the above technical solution, the magnetic connection of the permanent magnet is used to make the cleaning part adhere to the connecting cover after cleaning, so as to avoid pulling it at will and to provide a fixed cleaning part. When the cleaning part needs to be used, a pulling force greater than the magnetic force can be applied to the cleaning part to detach it from the permanent magnet.

[0019] Optionally, the first connector and the second connector are detachably connected to the inner core.

[0020] By adopting the above technical solution, the first connector and the second connector can be easily disassembled. After disassembly, the inner core is no longer restricted, and the cleaning parts can be detached from the surface of the inner core, thereby completing the replacement or repair.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. After prolonged use, impurities accumulate on the surface of the filter element. Therefore, maintenance personnel should periodically pull the cleaning component to move it along the inner core surface and clean the impurities. During the movement, the cleaning component moves the impurities to the receiving component, where they fall and are temporarily collected. The first and second connecting components restrict the position of the cleaning component, preventing it from leaving the inner core area, thus facilitating the cleaning of impurities from the filter element. 2. The connecting caps corresponding to the first and second connecting parts respectively restrict both ends of the inner core, so that the cleaning part cannot be separated from the inner core. When the cleaning part does not need to be cleaned or after cleaning is completed, it can be fixed in position by the fastening part, so that the filter element will not be affected by the cleaning part during daily use. 3. When the connecting cover is separated by multiple sockets, the connecting cover will not break, ensuring the stability of the connection between the connecting cover and the inner core. Then, the insertion action of the receiving parts is used to insert the receiving parts into the sockets. When multiple sockets are filled, multiple receiving parts form a complete ring structure. 4. The receiving part adopts an arc-shaped groove structure that can be locked onto the receiving interface, thereby improving the efficiency of removing the receiving part from the receiving interface for replacement or cleaning.

In the representation of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0029] This application discloses a UPE filter element.

[0030] A type of UPE filter element, reference Figure 1 As shown, it includes a first connector 1, a second connector 2, a cleaning component 3, and an inner core 5; the first connector 1 and the second connector 2 are respectively connected to the two ends of the inner core 5, which is the filter element. It can be a pleated microporous filter element with a flow guiding layer, filter membrane, and other structures to achieve filtration effect.

[0031] The outer diameters of the first connector 1 and the second connector 2 are both larger than the outer diameter of the inner core 5, so that the first connector 1 and the second connector 2 can be sleeved and fixedly installed on both ends of the inner core 5. The connection method can be heat fusion connection or adhesive bonding, depending on the requirements.

[0032] The cleaning component 3 is fitted onto the inner core 5 and moves along the surface of the inner core 5 to clean the surface of the inner core 5. The cleaning component 3 includes a cleaning ring with an inner diameter larger than that of the inner core 5 and can move along the surface of the inner core 5. The inner wall of the cleaning ring is provided with several cleaning brushes. The cleaning brushes contact the inner core 5, so that when the cleaning ring moves along the inner core 5, the cleaning brushes contact the surface of the inner core 5, thereby removing impurities from the surface of the inner core 5.

[0033] The first connector 1 or the second connector 2 is provided with a receiving member 4. The receiving member 4 can be a receiving ring, and the receiving ring has an inner recess. The impurities cleaned by the cleaning member 3 move along the inner core 5 to the receiving member 4. The inner recess of the receiving member 4 can temporarily store the impurities.

[0034] The installation position of the receiving part 4 can refer to the position of the first connecting part 1 or the second connecting part 2. If the first connecting part 1 is located below and the second connecting part 2 is located above, then the receiving part 4 is installed at the first connecting part 1, so that impurities can fall to the receiving part 4 along the cleaning part 3 and the effect of gravity. Conversely, if one end of the inner core 5 with the second connecting part 2 is located below, then the receiving part 4 is installed on the second connecting part 2.

[0035] Specifically, after prolonged use, impurities accumulate on the surface of the filter element. Therefore, maintenance personnel periodically pull the cleaning component 3 to move it along the surface of the inner core 5 and clean the impurities on the surface of the inner core 5. During the movement, the cleaning component 3 moves the impurities synchronously to the receiving component 4, where they fall into the receiving component 4 for temporary collection. The first connecting component 1 and the second connecting component 2 restrict the position of the cleaning component 3, preventing it from leaving the inner core 5, thus facilitating the cleaning of impurities from the filter element.

[0036] If stubborn impurities are encountered, the cleaning component 3 can move up and down along the extension direction of the inner core 5 to achieve a horizontal cleaning effect, and it can also rotate along the axis of the inner core 5. The rotation allows the cleaning brush of the cleaning component 3 to thoroughly clean the impurities, and then it can move up and down along the extension direction of the inner core 5.

[0037] Further reference Figure 2 As shown, the first connector 1 and the second connector 2 have the same structure. Therefore, the figure shows the first connector 1 as an example, which includes a connecting cover 11 and a fastening part 12. The connecting cover 11 has a receiving interface 111 for the receiving part 4 to be inserted. The connecting cover 11 has a connecting port in the middle. The connecting port is consistent with the outer diameter of the inner core 5, so that the connecting cover 11 can be connected to the inner core 5 through the connecting port. It can be connected by hot melting or adhesive. The receiving interface 111 serves as the connection point of the receiving part 4, and the receiving part 4 can be stuck in the receiving interface 111.

[0038] The fastening part 12 is connected to the connecting cover 11, and the installation position is located on the side of the connecting cover 11 facing away from the end of the inner core 5. The cleaning part 3 is detachably connected to the fastening part 12. The detachable connection method can be snap-fit. The fastening part 12 can be a snap block. The cleaning part 3 is provided with an elastic snap-fit ​​protrusion. The surface of the snap block can be provided with a snap groove. The snap-fit ​​protrusion can be snapped into the snap groove. When it is necessary to remove it, the cleaning part 3 can be disassembled by pulling it forcefully.

[0039] Specifically, the connecting caps 11 corresponding to the first connector 1 and the second connector 2 respectively restrict both ends of the inner core 5, so that the cleaning component 3 cannot be separated from the inner core 5. When the cleaning component 3 does not need to be cleaned or after cleaning is completed, it can be fixed in position by the fastening part 12, so that the filter element will not be affected by the cleaning component 3 during daily use.

[0040] Furthermore, refer to Figure 2 As shown, the first connector 1 and the second connector 2 are detachably connected to the inner core 5. The detachable connection can be a threaded connection, that is, the end of the inner core 5 is provided with an external thread, and the connection ports on the first connector 1 and the second connector 2 are provided with internal threads. Thus, the first connector 1 and the second connector 2 can be easily disassembled through the threaded connection. After disassembly, the inner core 5 is no longer restricted, and the cleaning part 3 can be detached from the surface of the inner core 5, thereby completing the replacement or repair.

[0041] When using a threaded connection, a connecting cylinder 13 can be provided at the connecting cover 11 of the first connecting member 1 and the second connecting member 2. The connecting cylinder 13 replaces the connecting port. The connecting cylinder 13 has a larger range, which makes the external thread connection area with the inner core 5 larger, thus making the connection more stable. A sealing structure such as a sealing ring or sealing membrane can be provided inside the connecting cylinder 13.

[0042] In some embodiments, reference Figure 1As shown, there are 2-4 receiving interfaces 111, and the number of receiving parts 4 is the same. If there are four receiving interfaces 111, then there are four receiving parts 4. The receiving parts 4 correspond one-to-one with the receiving interfaces 111, so that each receiving part 4 is inserted into a single receiving interface 111 in sequence. This application takes four receiving interfaces 111 as an example. Only one receiving part 4 is inserted in the figure for easy distinction.

[0043] Four receiving ports 111 are arranged in a ring-shaped radial pattern around the inner core 5. The receiving parts 4 are inserted into the receiving ports 111 and then connected end to end to form a complete ring structure to ensure that impurities can be stably recovered.

[0044] Further reference Figure 3 and Figure 4 As shown, the receiving part 4 adopts an arc-shaped groove with an inclined surface and a trapezoidal or conical cross-section. This makes the groove opening at the top of the arc-shaped groove larger than the receiving interface 111 and smaller than the receiving interface 111 at the bottom. Because the groove opening of the receiving part 4 is larger than the diameter of the receiving interface 111, the receiving part 4 can be stuck on the receiving interface 111 through the groove opening and cannot be detached from the receiving interface 111. When it is necessary to remove it from the receiving interface 111, the maintenance personnel push the bottom of the receiving part 4 upward from the receiving interface 111 on the bottom side of the connecting cover 11, so that the receiving part 4 is pushed out from the receiving interface 111, thus achieving the separation of the receiving part 4. This method allows the inner groove of the receiving part 4 to be easily removed by the maintenance personnel for replacement or cleaning after it is full of impurities.

[0045] Since the adjacent receiving interfaces 111 are disconnected from each other, they are not connected. Through the arc-shaped groove structure of the receiving component 4, the top can extend out of the receiving interface 111, allowing the adjacent receiving components 4 to connect with each other and form a complete ring structure. After the connection, the inclined surface of the inner wall of the receiving component 4 ensures that impurities stably slide into the receiving component 4.

[0046] In some embodiments, reference Figure 4 and Figure 5 As shown, a plurality of guide posts 6 are provided between the two connecting covers 11. The plurality of guide posts 6 are arranged around the inner core 5. The cleaning component is located within the guiding range of the plurality of guide posts 6 and contacts the guide posts 6. The guide posts 6 provide a limit for the cleaning component 3. The number of guide posts 6 is preferably three to four. Taking three as an example, the guide posts 6 are arranged at 120° intervals with the axis of the inner core 5 as the center. The cleaning component 3 is within the limiting space of the three guide posts 6 and contacts the outer wall of the three guide posts 6. The third guide post 6 in the figure is obscured and therefore not shown.

[0047] The guide post 6 ensures that the inner wall of the cleaning component 3 does not stick tightly to the inner core 5, and all positions of the inner core 5 are subjected to the average force of the cleaning component 3. This prevents the cleaning component 3 from being subjected to excessive force at a certain position and damaging the inner core 5, thus improving the stability of use.

[0048] Furthermore, the connecting cover 11 has a separation port 112, and the guide post 6 extends outward from the connecting cover 11 through the separation port 112. The extended part has external threads and a threaded part 61 is screwed to the extended part. That is, the length of the guide post 6 is longer than the distance between the two connecting covers 11, so that the guide post 6 can pass through the separation port 112 and pass through the two connecting covers 11. The guide post 6 is screwed to the connecting cover 11 through the external threads at both ends of the guide post 6 and screwed to the threaded part 61, so that the guide post 6 is screwed to the connecting cover 11 and cannot be detached. At the same time, the cleaning part 3 is limited. When disassembly is required, the threaded part 61 can be unscrewed. The threaded part 61 can be a nut.

[0049] The guide post 6 can be easily fixed and disassembled through the separation port 112 and the threaded part 61, which facilitates subsequent disassembly. After the guide post 6 is disassembled, when the first connector 1 and the second connector 2 are detachably connected to the inner core 5, the first connector 1 or the second connector 2 can be disassembled from the inner core 5, so that the cleaning part 3 can move along the inner core 5 and is freed from the restraint of the first connector 1 or the second connector 2, and the cleaning part 3 can be easily removed.

[0050] Furthermore, the fastening part 12 is made of permanent magnet, and the cleaning part 3 contains magnetic material. For example, an iron sheet is provided inside the cleaning part 3. The iron sheet is magnetically connected to the fastening part 12 of the permanent magnet. The iron sheet can be embedded inside the cleaning part 3 to avoid contact with external air or moisture and reduce the risk of oxidation.

[0051] The cleaning component 3 is attracted to the connecting cover 11 after cleaning by the magnetic connection of the permanent magnet, so as to prevent it from being pulled randomly and to fix the cleaning part. When the cleaning component 3 needs to be used, a pulling force greater than the magnetic force can be applied to the cleaning component 3 to remove it from the permanent magnet.

[0052] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
