Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a quick-release and assembly structure for filter elements in filtration equipment. Background Technology

[0002] Filtration equipment is an indispensable fluid handling device in industrial production and civil applications. It is widely used to remove particulate impurities from liquids or gases to ensure the smooth progress of subsequent processes or the purity of the final product.

[0003] In filtration equipment, the filter element is the key component for performing the filtration function. However, as operating time increases, the filter element gradually becomes clogged due to the trapping of impurities, leading to increased filtration pressure differential and decreased flow rate. Therefore, the filter element must be cleaned or replaced regularly to maintain the filtration efficiency and normal operation of the equipment.

[0004] In existing technical solutions, in order to ensure the sealing of the equipment during pressurized operation, the filter element is usually fixed and the filter cartridge cover is closed by flange docking with multiple bolts, or by using a large-diameter threaded tightening structure.

[0005] However, this structure reveals significant shortcomings when maintenance is required: disassembling multiple fastening bolts or unscrewing large-diameter threaded caps is extremely time-consuming and labor-intensive, often requiring specialized tools such as wrenches. In situations where frequent filter replacements are needed, this cumbersome disassembly and assembly process severely restricts maintenance efficiency and increases equipment downtime.

[0006] Therefore, this utility model proposes a quick-release and assembly structure for filter elements in filtration equipment to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems that existing filter equipment typically uses bolts or threads to fix the filter element, resulting in cumbersome disassembly and assembly, time-consuming and labor-intensive processes, and low maintenance efficiency, this utility model aims to provide a filter equipment filter element quick disassembly and assembly structure with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a quick-release structure for filter cartridges in a filtration device, comprising: the filter cartridge; and the quick-release assembly, wherein the quick-release assembly is installed inside the filter cartridge.

[0009] The quick-release assembly includes the connecting plate, which is fixedly connected to the inside of the filter cartridge; the quick-release assembly also includes the filter element, which is detachably inserted into the connecting plate.

[0010] The quick-release assembly also includes a filter element retaining cover, which abuts against the upper end of the filter element.

[0011] Furthermore, the upper surface of the connecting plate is provided with the slot, and the bottom of the filter element fixing cover is provided with the latch.

[0012] The filter element fixing cover and the connecting plate are detachably rotated and locked by the cooperation of the bolt and the slot. When the filter element fixing cover is rotated, the bolt is driven to engage in the slot or disengage from the slot, thereby achieving quick fixing or unlocking of the filter element.

[0013] Preferably, the handle is fixedly connected to the top of the filter element. This handle allows the operator to directly grasp it after the filter element fixing cover is removed, making it easier to pull the filter element from the connecting plate and reducing effort.

[0014] Preferably, the connecting plate has a water inlet hole that penetrates its surface. The water inlet hole allows the liquid to be filtered to flow in from the inlet end of the filter cartridge, pass smoothly through the connecting plate, and flow to the filter element for filtration.

[0015] Preferably, the connecting plate is further provided with the fixing plate and the fixing buckle. The lower end of the filter element is fixed and installed by the fixing plate and the fixing buckle. This design provides bottom positioning and support for the filter element, ensuring its verticality and stability during installation and filtration.

[0016] Preferably, the filter cartridge has a top cover at its top opening, and the top cover is detachably locked to the filter cartridge via a connecting buckle. This connecting buckle design replaces the traditional bolt flange, greatly simplifying the operation of opening the top cover for internal maintenance, and together with the quick-release assembly, enables rapid overall maintenance.

[0017] Preferably, the filter cartridge has an inlet and an outlet on its wall. The inlet and outlet serve as fluid interfaces for the device, respectively connecting to the pipeline to be filtered and discharging the filtered clean liquid.

[0018] Preferably, the filter cartridge has a drain end at its bottom. The drain end is preferably located at the lowest point of the filter cartridge to facilitate the periodic discharge of impurities and waste liquid that have settled at the bottom during equipment operation, thus keeping the inside of the filter cartridge clean.

[0019] Preferably, the support leg is fixedly connected to the bottom outer wall of the filter cartridge. The support leg provides stable physical support for the entire device, ensuring that the device can be stably placed on the ground or foundation for operation. This utility model has the following beneficial effects: 1. This utility model solves the problem of cumbersome, time-consuming, and laborious disassembly and assembly caused by the existing technology of relying on bolts or threads to fix the filter element, by setting a quick-release structure in which the filter element fixing cover with a buckle cooperates with the connecting plate with a slot. It achieves the effect of quickly unlocking or locking the filter element with just a simple rotation, which greatly improves maintenance efficiency.

[0020] 2. This utility model solves the problem of the filter element being difficult to grasp and lift by hand after being wetted or tightly installed by setting a handle on the top of the filter element. It achieves the effect of making it easier for operators to apply force and quickly lift the filter element out of the connecting plate, making the operation more labor-saving and convenient.

[0021] 3. This utility model, by adopting a quick-opening and closing top cover with a connecting buckle and a rotating filter element fixing cover, solves the overall problem of long time and complicated steps in the traditional maintenance process, from opening the equipment shell to disassembling the core components. It achieves the overall beneficial effect of no complicated tools required from opening the cover to taking out the filter element, and the operation process is simple and quick, significantly shortening the equipment downtime for maintenance.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example: Please refer to Figures 1 to 4 This utility model provides a quick-disassembly and assembly structure for filter elements in a filtration device, which aims to solve the problems of cumbersome filter element disassembly and assembly and low maintenance efficiency due to reliance on specific tools in the prior art.

[0026] like Figure 1 As shown, the quick-release structure of the filter element of this filtration device mainly consists of the filter cartridge 1, which serves as the external support, and the quick-release component 6 located inside the filter cartridge 1, which performs the core filtration and quick-release functions. The filter cartridge 1 has a hollow cavity structure, which provides installation space and liquid flow channels for the internal components.

[0027] To meet the normal operation and access requirements of the equipment, the filter cartridge 1 is provided with an inlet 2 and an outlet 7 on its wall. The inlet 2 is used to introduce the liquid containing impurities to be filtered into the filter cartridge 1, and the outlet 7 is used to export the clean liquid after filtration. The lowest point of the bottom of the filter cartridge 1 is provided with a drain end 5, which is used to periodically discharge the impurities that have settled at the bottom of the filter cartridge 1.

[0028] Multiple sets of support legs 8 are fixedly connected to the bottom outer wall of the filter cartridge 1. The support legs 8 are used to achieve stable vertical installation of the equipment on the ground. The top of the filter cartridge 1 is designed with an open structure to facilitate internal maintenance. The top opening is fitted with a cover 4. The cover 4 and the top edge of the filter cartridge 1 are detachably locked together by a connecting buckle 3. When internal maintenance is required, the cover 4 and the filter cartridge 1 can be quickly separated by operating the connecting buckle 3, exposing the quick-release assembly 6 inside.

[0029] The quick-release assembly 6 is installed in the internal cavity of the filter cartridge 1. From bottom to top, it generally includes a connecting plate 601 fixedly connected to the inner wall of the filter cartridge 1, several filter elements 605 that are detachably inserted into the connecting plate 601 in a vertical position, and a filter element fixing cover 602 located at the top of the filter element 605 for pressing and fixing. The components cooperate through a specific mechanical structure to form a stable and easy-to-disassemble filter unit as a whole.

[0030] To solve the above-mentioned technical problems, the quick-release assembly 6 achieves quick unlocking and fixing of the filter element 605 through a specific structural fit and connection relationship formed between the filter element fixing cover 602 and the connecting plate 601.

[0031] Please refer to the following carefully. Figure 1 , Figure 3 and Figure 4 The quick-release component 6 will be described in detail below: The connecting plate 601 serves as the mounting base for the quick-release assembly 6. Its upper surface is provided with a locking groove 606. The connecting plate 601 is also provided with a water inlet hole 603 that penetrates its surface to guide the liquid flow to the filter element 605. The lower part of the connecting plate 601 is also provided with a fixing plate 608 and a fixing buckle 609 for limiting the bottom of the filter element 605.

[0032] The filter element fixing cover 602 serves as the locking component of the quick-release assembly 6. A latch 607 is provided at the bottom of the cover corresponding to the slot 606. During installation, the filter element fixing cover 602 abuts against the upper end of the filter element 605.

[0033] In the assembled state, the lower end of the filter element 605 is initially limited by the fixing plate 608 and the fixing buckle 609. Then, the filter element fixing cover 602 is covered. By rotating the filter element fixing cover 602, the bottom bolt 607 is driven to cooperate with the groove 606 on the upper surface of the connecting plate 601. When the bolt 607 rotates into the locking position of the groove 606, the filter element fixing cover 602 is locked on the connecting plate 601. At the same time, the filter element 605 is firmly pressed by the abutment force.

[0034] During disassembly, the filter element fixing cover 602 is rotated in the opposite direction, causing the latch 607 to disengage from the slot 606. The filter element fixing cover 602 can then be unlocked and removed. This rotating snap-fit ​​structure ensures the quickness and convenience of fixing and unlocking the filter element 605.

[0035] To further enhance the ease of disassembly and assembly, a handle 604 is fixedly connected to the top of the filter element 605. After the filter element fixing cover 602 is removed, the operator can directly grasp the handle 604 to pull the filter element 605 out of the connecting plate 601.

[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, for ease of maintenance and operation of the quick-release assembly 6, please refer to... Figure 1 The filter cartridge 1 has a top cover 4 at the top opening. The top cover 4 and the filter cartridge 1 are detachably locked by a connecting buckle 3. The specific structure of the connecting buckle 3 can be a pull buckle, a snap buckle, or a wrench-type locking component, ensuring that the operator can quickly open or close the top cover 4 without complicated tools.

[0037] As a preferred embodiment, in order to construct a complete fluid passage, please refer to... Figure 1The filter cartridge 1 also has an inlet end 2 and an outlet end 7 integrally formed or welded on its wall. Both the inlet end 2 and the outlet end 7 are pipe interface structures, which are used to connect the external filter pipe and the cleaning liquid pipe, respectively.

[0038] As a preferred embodiment, to facilitate the cleaning of deposited impurities inside the filter cartridge 1, please refer to... Figure 1 The filter cartridge 1 has a drain end 5 at its lowest point. The drain end 5 is preferably a pipe interface with a valve. It is kept closed and sealed when not draining, and the valve is opened to discharge when draining is required.

[0039] As a preferred implementation method, to achieve stable placement of the equipment, please refer to... Figure 1 and Figure 2 The bottom outer wall of the filter cartridge 1 is fixedly connected with a support leg 8. The support leg 8 can be multiple evenly distributed columnar legs or a frame structure welded from profiles, providing stable ground support for the entire equipment.

[0040] The working principle of the quick-release and disassembly structure for the filter element of this utility model is as follows: When the equipment performs the filtration function, the liquid containing impurities enters the filter cartridge 1 from the inlet end 2. The liquid flows through the inlet hole 603 on the connecting plate 601 in the quick-release assembly 6, and then the liquid is forced to flow through the filter element 605 which is detachably inserted on the connecting plate 601. During this process, the impurities in the liquid are effectively intercepted by the filter element 605. The filtered clean liquid is collected in the filter cartridge 1 and finally flows out of the equipment from the outlet end 7. The drain end 5 located at the bottom of the filter cartridge 1 can be used to periodically discharge the deposited impurities.

[0041] When the equipment is quickly disassembled and maintained, if the filter element 605 needs to be cleaned or replaced due to impurities, the operator first operates the connecting buckle 3 to quickly separate the top cover 4 from the filter cartridge 1, thereby opening the top opening of the filter cartridge 1.

[0042] Subsequently, the operator applies a rotational force to the filter element fixing cover 602 that abuts against the upper end of the filter element 605. This rotational action drives the latch 607 at the bottom of the filter element fixing cover 602 to move along the slot 606 on the upper surface of the connecting plate 601 until the latch 607 is completely disengaged from the slot 606. At this time, the filter element fixing cover 602 is quickly unlocked and can be removed.

[0043] After the filter element fixing cover 602 is removed, the operator can directly hold the handle 604 on the top of the filter element 605 and pull the filter element 605 vertically upward, so that its lower end is disengaged from the limiting position of the fixing plate 608 and fixing buckle 609 on the connecting plate 601, thereby completing the quick disassembly of the filter element 605. The whole process does not require the removal of bolts, which is convenient and efficient.

[0044] When installing the filter element 605, perform the above reverse operation: insert the filter element 605 back into place, cover the filter element fixing cover 602 and rotate it in the opposite direction so that the latch 607 can be re-engaged into the slot 606 to achieve quick locking.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
