Description

Technical Field

[0001] This utility model relates to the technical field of filter installation devices, and in particular to a high-sealing, quick-installation and removal filter installation device. Background Technology

[0002] In the field of liquid or gas purification, filter installation devices need to balance easy maintenance, reliable sealing and high-efficiency filtration. They must be able to easily and quickly replace filters to ensure continuous operation, prevent leakage of filter media or infiltration of external impurities, and meet the requirements for removing fine impurities.

[0003] However, existing filter installation devices have significant shortcomings: most existing filters are fixed with bolts or connected with flanges, requiring various tools for disassembly and assembly, which is cumbersome and time-consuming. This not only increases the labor intensity of maintenance personnel, but also easily leads to poor sealing due to improper installation, resulting in leakage of filter media or seepage of unfiltered substances, affecting filtration purity. At the same time, existing devices rely solely on carbon filter for filtration, which has limited interception capabilities for fine particles, colloids and other impurities, and cannot meet high-standard filtration requirements. Furthermore, in traditional devices, auxiliary filtration components are often integrated with the filter, requiring the entire unit to be replaced, resulting in high maintenance costs and difficulty in adapting to different filtration precision scenarios.

[0004] Therefore, those skilled in the art have provided a high-sealing, quick-installation filter installation device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-sealing, quick-installation filter installation device. Through its assembly mechanism, the activated carbon filter can be quickly installed and removed without tools, shortening maintenance time. Furthermore, its precise positioning via a limiting structure and enhanced sealing via double threaded connections prevent leakage of the filter media or infiltration of external substances. Simultaneously, through its functional mechanisms, the polyacrylonitrile ultrafiltration membrane layer and the activated carbon filter form a dual filtration system, improving the removal of fine impurities and ensuring filtration accuracy. The ultrafiltration membrane layer can be individually removed and replaced via threads, eliminating the need to replace the entire filter, reducing maintenance costs. It can also adapt to different filtration needs. Together, these features enhance the practicality, filtration effect, and ease of maintenance of the filter installation device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-sealing, quick-installation filter installation device includes a mounting side plate and multiple carbon barrel filters. An assembly mechanism is provided between the mounting side plate and the multiple carbon barrel filters, and a functional mechanism is provided on the rear end face of each of the multiple carbon barrel filters. The assembly mechanism includes multiple assembly ports, which are respectively opened on the rear end face of the mounting side plate. The carbon barrel filter is fitted into the assembly port. The inner wall of the assembly port has three fixing ports. Each of the three fixing ports has an insertion port on one side of its front inner wall. Each insertion port has a limiting groove on one side of its inner wall. Three connecting plates are fixedly connected to the upper part of the outer wall of the carbon barrel filter. Each of the three connecting plates has a limiting rod fixedly connected to its front end face. The limiting rod is movably fitted into the insertion port. The limiting rod is slidably disposed in the limiting groove. The front end of the limiting rod is fixedly connected to a limiting end. The rear end face of the limiting end face is fitted against the front end face of the mounting side plate. The above technical solution provides a precise installation space for the carbon filter through the assembly port, ensuring that the filter can be quickly aligned and engaged. The insertion port inside the fixing port facilitates the initial insertion of the limiting rod. After rotating the filter, the limiting rod slides along the limiting groove to the end, forming a mechanical lock. Combined with the fit between the limiting end and the front face of the mounting side plate, it prevents the filter from shifting forward or backward, solving the problem of traditional filter installation lacking a precise positioning structure and being prone to displacement. This lays the foundation for subsequent sealing and reinforcement, while also achieving tool-free initial fixing and improving assembly efficiency.

[0007] Furthermore, the functional mechanism includes a fixing ring and an annular threaded groove, an ultrafiltration membrane layer is fixedly sleeved inside the fixing ring, and the fixing ring is fitted to the carbon barrel filter; The above technical solution provides a stable mounting carrier for the ultrafiltration membrane layer through the fixing ring, ensuring that the membrane layer is flat and wrinkle-free. The fixing ring fits tightly with the carbon filter, allowing the medium to be filtered to flow completely through the ultrafiltration membrane layer before entering the carbon filter. This avoids media circling and incomplete filtration, solving the problem of insufficient interception of fine impurities by traditional single carbon filter. The dual filtration improves the purification effect and meets higher filtration standards.

[0008] Furthermore, the ultrafiltration membrane layer is made of polyacrylonitrile material; Through the above technical solution, the material has excellent chemical resistance and mechanical strength, which can effectively intercept impurities such as fine particles, colloids, and large organic molecules. It is not easily damaged or degraded with long-term use, solving the problems of easy corrosion and short life of traditional ultrafiltration membrane materials, extending the membrane replacement cycle, reducing maintenance costs, ensuring stable filtration accuracy, and avoiding impurities from seeping in due to membrane damage, which would affect filtration purity.

[0009] Furthermore, the annular threaded groove is formed on the rear end face of the carbon barrel filter, and the front end face of the fixing ring is fixedly connected to an annular threaded plate, which is threadedly sleeved in the annular threaded groove. The above technical solution uses the threaded engagement of the annular threaded plate and the annular threaded groove to ensure that the fixing ring is securely connected to the rear end of the carbon filter, preventing the fixing ring from falling off due to pressure fluctuations during filtration. At the same time, the fixing ring can be quickly disassembled by rotating in the opposite direction, making it convenient to replace the ultrafiltration membrane layer separately without replacing the entire filter. This solves the problem of high maintenance costs associated with the traditional integrated design of the membrane layer and filter, improves the flexibility of component replacement, and reduces operating costs.

[0010] Furthermore, a first external threaded ring is fixedly sleeved on the outer wall of the carbon barrel filter, and multiple second external threaded rings are fixedly connected to the rear end face of the mounting side plate. A threaded collar is threadedly sleeved on the outer wall of the first external threaded ring, and the front end of the threaded collar is threadedly sleeved on the second external threaded ring. The above technical solution uses a threaded collar to connect with both the No. 1 and No. 2 external threaded rings, tightly locking the carbon barrel filter to the mounting side plate and eliminating gaps at the connection point. This effectively prevents leakage of the filter media or infiltration of unfiltered substances from the outside, solves the problem of insufficient sealing in traditional initial fixing, improves the overall sealing performance of the device, and ensures the stability and purity of the filtration process. At the same time, the threaded connection method facilitates subsequent disassembly and does not affect the advantages of quick installation and removal.

[0011] Furthermore, a limiting ring is fixedly sleeved on the rear part of the outer wall of the first external threaded ring; The above technical solution, by fixing the limiting ring on the outer wall of the first external threaded ring, can prevent the threaded ring from being over-tightened backward, avoid collision and squeezing between the threaded ring and the carbon barrel filter or connecting plate, which would cause deformation and damage to the components. At the same time, it ensures that the threaded ring can stay in the same position every time it is tightened, ensuring that the sealing performance of each filter is consistent after assembly, avoiding differences in sealing effect due to different degrees of tightening, and improving the standardization and reliability of device assembly.

[0012] This utility model has the following beneficial effects: 1. This utility model proposes a high-sealing, quick-installation filter installation device. Through the added assembly mechanism, the filter can be installed and removed without tools, solving the problems of cumbersome and time-consuming disassembly and assembly of traditional bolt fixing methods. This significantly shortens the time for maintenance or filter replacement, improves equipment maintenance efficiency, and the cooperation between the limiting rod and the limiting groove achieves preliminary accurate positioning. The double threaded connection of the threaded collar enhances the assembly sealing, preventing filter media leakage from affecting the filtration effect. At the same time, it prevents unfiltered substances from seeping in, ensuring filtration purity. Furthermore, the setting of the limiting ring prevents the threaded collar from being over-tightened, which could damage the components and extend the service life of the device. It is suitable for scenarios that require frequent filter replacement.

[0013] 2. This utility model proposes a high-sealing, quick-installation filter installation device. Through the addition of functional mechanisms, the polyacrylonitrile ultrafiltration membrane layer can effectively intercept impurities such as fine particles and colloids. When used in conjunction with an activated carbon filter, it improves filtration accuracy and purification effect, solving the problem of incomplete removal of fine impurities by traditional single activated carbon filters. It meets higher filtration standards. Furthermore, the connection method of the annular threaded plate and annular threaded groove allows the ultrafiltration membrane layer to be disassembled and replaced separately without replacing the entire filter, reducing maintenance costs. At the same time, it is convenient to replace ultrafiltration membrane layers of different filtration calibers according to filtration needs, improving the adaptability of the device to different filtration scenarios and extending the service life of the activated carbon filter.

[0014] 3. This utility model proposes a high-sealing, quick-installation filter installation device. Through its assembly mechanism, the carbon filter can be quickly installed and removed without tools, shortening maintenance time. It also features precise positioning via a limiting structure and enhanced sealing via double threaded connections, preventing leakage of the filter media or infiltration of external substances. Simultaneously, through its functional mechanism, the polyacrylonitrile ultrafiltration membrane layer and the carbon filter form a dual filtration system, improving the removal of fine impurities and ensuring filtration accuracy. Furthermore, the ultrafiltration membrane layer can be individually disassembled and replaced via threads, eliminating the need to replace the entire filter, reducing maintenance costs. It can also adapt to different filtration needs. Together, these features enhance the practicality, filtration effect, and ease of maintenance of the filter installation device.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a specific embodiment: a high-sealing quick-installation filter installation device, including an installation side plate 1 and multiple carbon barrel filters 2, an assembly mechanism 3 is provided between the installation side plate 1 and the multiple carbon barrel filters 2, and a functional mechanism 4 is provided on the rear end face of the multiple carbon barrel filters 2. The assembly mechanism 3 includes multiple assembly ports 301, which are respectively opened on the rear end face of the mounting side plate 1. The charcoal barrel filter 2 is fitted into the assembly port 301. The inner wall of the assembly port 301 has three fixing ports 302. Each of the three fixing ports 302 has an insertion port 307 on one side of its front inner wall. The inner wall of one side of the insertion port 307 has a limiting groove 306. Three connecting plates 303 are fixedly connected to the upper part of the outer wall of the charcoal barrel filter 2. Each of the three connecting plates 303 has a limiting rod 304 fixedly connected to its front end face. The limiting rod 304 is movably fitted into the insertion port 307 and slides within the limiting groove 306. The front end of the 04 filter is fixedly connected to a limiting end 305. The rear end face of the limiting end 305 is fitted against the front end face of the mounting side plate 1. The assembly port 301 provides precise installation space for the carbon barrel filter 2, ensuring that the filter can be quickly aligned and engaged. The insertion port 307 in the fixing port 302 facilitates the initial insertion of the limiting rod 304. After rotating the filter, the limiting rod 304 slides along the limiting groove 306 to the end, forming a mechanical lock. Combined with the fit between the limiting end 305 and the front end face of the mounting side plate 1, it prevents the filter from shifting forward or backward, solving the problem of traditional filter installation lacking a precise positioning structure and being prone to displacement. This lays the foundation for subsequent sealing and reinforcement, while also achieving tool-free initial fixing. To improve assembly efficiency, a first external threaded ring 308 is fixedly fitted on the outer wall of the carbon barrel filter 2. Multiple second external threaded rings 309 are fixedly connected to the rear end face of the mounting side plate 1. A threaded collar 310 is threaded onto the outer wall of the first external threaded ring 308, and the front end of the threaded collar 310 is threaded onto the second external threaded rings 309. The threaded collar 310 simultaneously connects to both the first and second external threaded rings 308 and 309, tightly locking the carbon barrel filter 2 to the mounting side plate 1, eliminating gaps at the connection point, effectively preventing leakage of the filter media or infiltration of unfiltered external substances, solving the problem of insufficient sealing in traditional initial fixing, and improving the overall sealing of the device. Performance ensures the stability and purity of the filtration process. The threaded connection facilitates subsequent disassembly without compromising the advantages of quick assembly and disassembly. A limiting ring 311 is fixedly fitted on the outer wall of the first external threaded ring 308 at the rear. The limiting ring 311 is fixedly fitted on the outer wall of the first external threaded ring 308 to prevent the threaded collar 310 from being excessively tightened to the rear, thus avoiding collision and squeezing between the threaded collar 310 and the carbon barrel filter 2 or the connecting plate 303, which could lead to deformation and damage to the components. At the same time, it ensures that the threaded collar 310 can stay in the same position every time it is tightened, ensuring consistent sealing performance after the assembly of each filter, avoiding differences in sealing effect due to different degrees of tightening, and improving the standardization and reliability of the device assembly. Reference Figure 1 , Figure 3 and Figure 5The functional mechanism 4 includes a fixing ring 401 and an annular threaded groove 404. An ultrafiltration membrane layer 402 is fixedly sleeved inside the fixing ring 401. The fixing ring 401 is fitted snugly against the activated carbon filter 2, providing a stable mounting surface for the ultrafiltration membrane layer 402, ensuring the membrane layer is flat and wrinkle-free. The tight fit between the fixing ring 401 and the activated carbon filter 2 allows the filter media to completely flow through the ultrafiltration membrane layer 402 before entering the activated carbon filter 2, preventing media circumference and incomplete filtration. This solves the problem of insufficient interception of fine impurities in traditional single activated carbon filters, improving purification efficiency through dual filtration and meeting higher filtration standards. The ultrafiltration membrane layer 402 is made of polyacrylonitrile material, which possesses excellent chemical resistance and mechanical strength, effectively intercepting fine particles, colloids, and large organic molecules. It is also resistant to damage or degradation over long-term use, addressing the challenges of traditional ultrafiltration... To address the issues of easy corrosion and short lifespan of membrane material 402, this design extends the membrane replacement cycle, reduces maintenance costs, and ensures stable filtration accuracy. It prevents impurities from seeping in due to membrane damage, thus maintaining filtration purity. An annular threaded groove 404 is located on the rear end of the carbon filter 2. An annular threaded plate 403 is fixedly connected to the front end of the retaining ring 401. The annular threaded plate 403 is threaded into the annular threaded groove 404. Through the threaded engagement of the annular threaded plate 403 and the annular threaded groove 404, the retaining ring 401 is securely connected to the rear end of the carbon filter 2, preventing it from falling off due to pressure fluctuations during filtration. The retaining ring 401 can be quickly removed by reverse rotation, facilitating individual replacement of the ultrafiltration membrane layer 402 without replacing the entire filter. This solves the problems of traditional integrated membrane and filter designs and high maintenance costs, improving component replacement flexibility and reducing operating costs.

[0019] Working principle: When using this high-sealing quick-installation filter installation device, the assembly mechanism 3 first completes the assembly of the carbon barrel filter 2 and the mounting side plate 1: Align the carbon barrel filter 2 with the assembly port 301 on the rear end face of the mounting side plate 1 and insert it, so that the three connecting plates 303 on the outer wall of the carbon barrel filter 2 drive the limiting rod 304 to insert into the insertion port 307 of the fixing port 302 on the inner wall of the assembly port 301. Rotate the carbon barrel filter 2, and the limiting rod 304 slides along the limiting groove 306 to the end. At this time, the limiting rod 304 at the front end of the limiting rod 304... The rear end face of end cap 305 is attached to the front end face of mounting side plate 1 to complete the initial fixation. Then, rotate threaded collar 310 so that its front end is threadedly connected to the second external threaded collar 309 on the rear end face of mounting side plate 1, and its rear end is threadedly engaged with the first external threaded collar 308 on the outer wall of carbon barrel filter 2, until the front end of threaded collar 310 is attached to the limiting ring 311 on the outer wall of the first external threaded collar 308. High sealing fixation is achieved through double thread reinforcement to prevent leakage of filter media. Before performing filtration operations, assemble functional mechanism 4: The annular threaded plate 403 at the front end of the retaining ring 401 is aligned with the annular threaded groove 404 on the rear end face of the carbon filter 2. Rotating the retaining ring 401 causes the threads to engage. The polyacrylonitrile ultrafiltration membrane layer 402 inside the retaining ring 401 adheres to the rear end face of the carbon filter 2, forming a dual filtration structure. During filtration, liquid or gas first flows through the ultrafiltration membrane layer 402, intercepting fine particles, colloids, and other impurities, before entering the carbon filter 2 for deep purification, achieving high-efficiency filtration. When the ultrafiltration membrane layer 402 needs to be replaced... Rotate the retaining ring 401 in the reverse direction to disengage the annular threaded plate 403 from the annular threaded groove 404, and then remove the retaining ring 401 to replace the new ultrafiltration membrane layer 402. If the carbon barrel filter 2 needs to be replaced, rotate the threaded collar 310 in the reverse direction to disengage it from the second external threaded ring 309 and the first external threaded ring 308, and then rotate the carbon barrel filter 2 in the reverse direction to allow the limiting rod 304 to slide back to the insertion port 307 along the limiting bend 306. Pull out the carbon barrel filter 2 to complete the replacement. The whole process does not require the use of tools, achieving quick installation and removal.
