Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a combined filter element. Background Technology

[0002] In today's industrial sectors, fluid treatment often involves the use of different filter cartridges. Currently, filter cartridges and coalescing cartridges are typically used separately, and based on these two different functions, they are designed as two independent devices: filters and coalescers. In practical applications, to achieve the desired fluid treatment effect, it is often necessary to use filters and coalescers in series.

[0003] However, this traditional design approach has several drawbacks. First, since the filter and coalescer are two separate devices, they require a significant amount of space during installation and use. This poses a considerable challenge for workplaces with limited space, potentially impacting the overall layout and increasing site rental or construction costs. Second, the purchase and installation of these two separate devices require substantial investment, undoubtedly increasing the overall project cost.

[0004] Despite the emergence of coalescing filter cartridges with the continuous development of technology, existing coalescing filter cartridges still have problems in practical applications. Current coalescing filter cartridges are installed separately in the filter and coalescer, a configuration that does not fundamentally solve the shortcomings of traditional designs. The problem of large equipment footprint persists, requiring significant space for multiple units; furthermore, the numerous connecting pipelines not only complicate the installation and commissioning of the entire system, increasing construction difficulty and cost, but also pose a potential risk of leakage, making subsequent maintenance and management more difficult. In addition, the multiple units and complex pipeline configuration further increase costs, requiring companies to incur greater economic burdens in equipment procurement, operation, and maintenance.

[0005] In summary, the existing filtration and coalescing equipment and filter element designs have significant shortcomings in terms of floor space, investment costs, and system complexity, and cannot meet the needs of modern industry for efficient, economical, and compact fluid handling equipment. Utility Model Content

[0006] The purpose of this invention is to provide a combined filter element to solve the problems existing in the prior art, combining the filter element and the coalescing filter element together for convenient use.

[0007] To achieve the above objectives, this utility model provides the following solution:

[0008] This utility model provides a combined filter element, comprising:

[0009] A support connector includes a support cylinder, a spacer ring, a support rod, and a nut. The support cylinder is cylindrical, and the support cylinder, the spacer ring, and the support rod are coaxial. One end of the support cylinder and the support rod are fixedly connected to the spacer ring, and the spacer ring is located between the support cylinder and the support rod. The nut is threaded to the end of the support rod away from the spacer ring. Multiple liquid permeable holes are provided on the side wall of the support cylinder.

[0010] The filter element is cylindrical and sleeved on the support cylinder, with one end of the filter element in contact with one side of the spacer ring.

[0011] A coalescing filter element is sleeved on the support rod, with one end of the coalescing filter element abutting against the other side of the spacer ring, and the nut abutting against the other end of the coalescing filter element.

[0012] Preferably, the other end of the filter element is provided with a handle.

[0013] Preferably, the support cylinder is made of a filter screen.

[0014] Preferably, the material of the support cylinder is metal.

[0015] Preferably, the filter element is cylindrical, and the end of the filter element away from the spacer ring is sealed.

[0016] Preferably, the maximum diameter of the coalescing filter element and the maximum diameter of the filter element are both smaller than the outer diameter of the spacer ring.

[0017] Preferably, the coalescing filter element is conical, and the diameter of the coalescing filter element gradually decreases from one end near the spacer ring to the other end.

[0018] Preferably, the inner diameter of the spacer ring, the inner diameter of the filter element, and the maximum inner diameter of the coalescing filter element are equal.

[0019] Preferably, the spacer ring connects the filter element and the coalescing filter element, and the spacer ring is made of metal.

[0020] Preferably, the support rod is connected to the spacer ring via at least two connecting rods, one end of which is fixedly connected to the support rod and the other end of which is fixedly connected to the spacer ring.

[0021] The present invention achieves the following technical advantages over the prior art:

[0022] This utility model's combined filter element effectively solves the problems of existing filtration and coalescing equipment and filter elements in terms of space, investment cost, and system complexity by combining a filter element and a coalescing filter element. It has the advantages of compact structure, convenient installation and maintenance, high filtration and coalescing efficiency, and good sealing performance, meeting the needs of modern industry for efficient, economical, and compact fluid processing equipment.

[0023] Furthermore, the support connector consists of a support cylinder, a spacer ring, a support rod, and a nut. The support cylinder is cylindrical, and the support cylinder, spacer ring, and support rod are coaxial. This coaxial design makes the entire filter element structure more stable, ensuring the concentricity of the filter element and the coalescing filter element during operation, thereby improving the efficiency and stability of filtration and coalescence.

[0024] Furthermore, one end of the support cylinder and the support rod are fixed to the spacer ring, and the spacer ring is located between the support cylinder and the support rod. The nut is threaded to the end of the support rod away from the spacer ring. This connection method makes the structure of the support connector compact and easy to assemble and disassemble, which facilitates the maintenance and replacement of the filter element in the later stage.

[0025] Furthermore, multiple fluid permeation holes are provided on the side wall of the support cylinder. These holes ensure that the fluid filtered by the well filter element can smoothly enter the support cylinder, then flow into the coalescing filter element, and then be filtered by the coalescing filter element, providing suitable fluid conditions for the subsequent coalescing process.

[0026] Furthermore, the filter element is cylindrical and fitted onto the support cylinder, with one end contacting one side of the spacer ring. This fitting method fully utilizes the supporting role of the support cylinder to ensure the stability of the filter element during operation. At the same time, it ensures a tight fit between the filter element and the support cylinder, preventing fluid leakage from the gap between the filter element and the support cylinder and improving the filtration effect. In addition, the filter element and the support cylinder are designed separately, allowing for easy separation of the filter element and the support cylinder after the filter element reaches the end of its service life for easy replacement.

[0027] Furthermore, a handle is provided at the other end of the filter element, which facilitates the installation, disassembly, and transportation of the filter element by the operator, improving the convenience of operation.

[0028] Furthermore, the filter element is cylindrical and sealed at the end away from the spacer ring. This structural design allows fluid to enter only from the side wall of the filter element, pass through the filter, and then flow out, thus ensuring the comprehensiveness and effectiveness of filtration and improving filtration quality.

[0029] Furthermore, the coalescing filter element is fitted onto the support rod, with one end abutting against the other side of the spacer ring, and the nut abutting against the other end of the coalescing filter element. This installation method provides the coalescing filter element with stable support on the support rod. At the same time, the position of the coalescing filter element can be finely adjusted and fixed through the abutting action of the nut, ensuring the stability of the coalescing filter element during operation.

[0030] Furthermore, the maximum diameter of both the coalescing filter element and the filter element is smaller than the outer diameter of the spacer ring. This size design allows the combined filter element to be installed in the filtration equipment. If the edge of the spacer ring is connected to the inner wall of the equipment, the spacer ring can isolate the two cavities on both sides, so that the filter element and the coalescing filter element are located in two different cavities, preventing the fluid that has not entered the filter element from mixing with the fluid that has flowed out of the coalescing filter element.

[0031] Furthermore, the coalescing filter element is conical, and its diameter gradually decreases from one end near the spacer ring to the other end. On the one hand, this conical structure design is more conducive to maintaining a stable fluid velocity after the fluid passes through the coalescing filter element, and a stable flow velocity is more conducive to the separation of the continuous phase and the discontinuous phase. On the other hand, this conical structure can increase the space between the coalescing filter element and the inner wall of the container, so that the droplets in the fluid can better aggregate and separate, and are less likely to form entrainment.

[0032] Furthermore, the inner diameter of the spacer ring, the inner diameter of the filter element, and the maximum inner diameter of the coalescing filter element are all equal. This dimensional matching ensures a tight fit between the filter element, the coalescing filter element, and the spacer ring, preventing fluid leakage at the joints and improving the overall sealing performance and efficiency of the combined filter element. It also ensures that the pressure drop remains stable as the fluid passes through the combined filter element.

[0033] Furthermore, the spacer ring connects the filter element and the coalescing filter element, and the material is metal. The metal spacer ring not only has good strength and stability and can withstand certain pressure and impact, but also effectively separates the filter element and the coalescing filter element, ensuring that their respective functions can be performed independently, while also preventing the filtered fluid from being contaminated again.

[0034] Furthermore, the support rod is connected to the spacer ring via at least two connecting rods. One end of the connecting rod is fixed to the support rod, and the other end is fixed to the spacer ring. This connection method enhances the connection strength between the support rod and the spacer ring, ensuring the overall stability of the support connection and thus ensuring the reliability of the entire combined filter element during operation.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] The purpose of this invention is to provide a combined filter element to solve the problems existing in the prior art, combining the filter element and the coalescing filter element together for convenient use.

[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1 As shown, this embodiment provides a combined filter element, including a support connector, a filter element 1, and a coalescing filter element 4. Specifically:

[0042] The support connector includes a support cylinder 2, a spacer ring 3, a support rod 5, and a nut 6. The support cylinder 2 is cylindrical, and the support cylinder 2, spacer ring 3, and support rod 5 are coaxial. This coaxial design makes the entire filter element structure more stable, ensuring the concentricity of the filter element 1 and the coalescing filter element 4 during operation, thereby improving the efficiency and stability of filtration and coalescence. The support cylinder 2 and the support rod 5 are fixedly connected to the spacer ring 3 at one end, and the spacer ring 3 is located between the support cylinder 2 and the support rod 5. The nut 6 is threaded to the end of the support rod 5 away from the spacer ring 3. This connection method makes the support connector structure compact and easy to assemble and disassemble, facilitating the maintenance and replacement of the filter element in the future. The side wall of the support cylinder 2 is provided with multiple liquid permeable holes. These liquid permeable holes ensure that the fluid filtered by the filter element 1 can smoothly enter the support cylinder 2, then flow into the coalescing filter element 4, and then be filtered by the coalescing filter element 4, providing suitable fluid conditions for the subsequent coalescence process.

[0043] The filter element 1 is cylindrical and sleeved on the support cylinder 2, with one end of the filter element 1 contacting one side of the spacer ring 3. This sleeved arrangement can fully utilize the supporting role of the support cylinder 2 to ensure the stability of the filter element 1 during operation; at the same time, it makes the fit between the filter element 1 and the support cylinder 2 tight, preventing fluid leakage from the gap between the filter element 1 and the support cylinder 2, thus improving the filtration effect; in addition, the filter element 1 and the support cylinder 2 are designed separately, so that when the service life of the filter element 1 is reached, the filter element 1 can be easily separated from the support cylinder 2 for replacement.

[0044] The coalescing filter element 4 is fitted onto the support rod 5, with one end of the coalescing filter element 4 abutting against the other side of the spacer ring 3, and the nut 6 abutting against the other end of the coalescing filter element 4. This installation method allows the coalescing filter element 4 to be stably supported on the support rod 5. At the same time, through the abutting action of the nut 6, the position of the coalescing filter element 4 can be finely adjusted and fixed, ensuring the stability of the coalescing filter element 4 during operation.

[0045] In the optional solutions of this embodiment, it is more preferred that the other end of the filter element 1 is provided with a handle 7. The handle 7 facilitates the installation, disassembly and transportation of the filter element by the operator, and improves the convenience of operation.

[0046] Regarding the structure of the support cylinder 2, specifically: the support cylinder 2 is made of filter screen (or mesh tube), and the material of the support cylinder 2 is metal. This type of support cylinder 2 is easy to manufacture, has strong support, and is low in cost.

[0047] In the optional schemes of this embodiment, it is more preferred that the filter element 1 is cylindrical and the end of the filter element 1 away from the spacer ring 3 is sealed. This structural design allows the fluid to enter only from the side wall of the filter element 1, and then flow out after filtration, thereby ensuring the comprehensiveness and effectiveness of filtration and improving the filtration quality.

[0048] In the optional scheme of this embodiment, it is more preferred that the maximum diameter of the coalescing filter element 4 and the maximum diameter of the filter element 1 are both smaller than the outer diameter of the spacer ring 3. This size design allows the combined filter element to isolate the two cavities when the edge of the spacer ring 3 is connected to the inner wall of the equipment, so that the filter element 1 and the coalescing filter element 4 are located in two different cavities, preventing the fluid that has not entered the filter element 1 from mixing with the fluid that flows out of the coalescing filter element 4.

[0049] In the optional scheme of this embodiment, it is more preferred that the coalescing filter element 4 is conical, and the diameter of the coalescing filter element 4 gradually decreases from one end near the spacer ring 3 to the other end. On the one hand, this conical structure design is more conducive to maintaining the stability of the fluid flow rate after the fluid passes through the coalescing filter element 4, and the stable flow rate is more conducive to the separation of the continuous phase and the discontinuous phase. On the other hand, this conical structure can increase the space between the coalescing filter element and the inner wall of the container, so that the droplets in the fluid can better aggregate and separate, and are less likely to form entrainment.

[0050] In the optional embodiments of this example, it is preferred that the inner diameter of the spacer ring 3, the inner diameter of the filter element 1, and the maximum inner diameter of the coalescing filter element 4 are equal. This dimensional matching ensures a tight fit between the filter element 1, the coalescing filter element 4, and the spacer ring 3, preventing fluid leakage at the connection points and improving the sealing performance and working efficiency of the entire combined filter element. It also ensures that the pressure drop remains stable as the fluid passes through the combined filter element.

[0051] In the optional scheme of this embodiment, it is more preferred that the septum ring 3 connects the filter element 1 and the coalescing filter element 4. The material of the septum ring 3 is metal. The metal septum ring 3 not only has good strength and stability and can withstand certain pressure and impact, but also effectively separates the filter element 1 and the coalescing filter element 4, ensuring that their respective functions can be performed independently, and at the same time preventing the filtered fluid from being contaminated again.

[0052] In the optional scheme of this embodiment, it is more preferred that the support rod 5 is connected to the spacer ring 3 by at least two connecting rods. One end of the connecting rod is fixed to the support rod 5 and the other end is fixed to the spacer ring 3. This connection method enhances the connection strength between the support rod 5 and the spacer ring 3, ensures the overall stability of the support connector, and thus ensures the reliability of the entire combined filter element during operation.

[0053] The working principle of the combined filter element in this embodiment is as follows:

[0054] During operation, the fluid first enters the filter element 1 through the outside and is filtered by the filter element 1. As the fluid passes through the filter element 1, impurities are filtered and intercepted. The filtered fluid then flows into the support cylinder 2 through the liquid permeation holes on the support cylinder 2, and then flows into the cavity between the coalescing filter element 4 and the support rod 5 through the center of the spacer ring 3. The coalescing filter element 4 is fitted onto the support rod 5, with one end abutting against the spacer ring 3 and the other end fixed by the nut 6. The conical shape of the coalescing filter element 4 causes the droplets in the fluid to gather and separate. The spacer ring 3 isolates the filter element 1 and the coalescing filter element 4, ensuring that each function independently. Furthermore, the spacer ring 3 matches the inner diameter of both and has a compact overall structure, ensuring a tight seal. Ultimately, efficient fluid filtration and coalescing treatment are achieved.

[0055] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
