Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a honeycomb stainless steel filter structure for water purification equipment. Background Technology

[0002] In the field of water purification equipment, the design of the filter structure is one of the core elements of equipment performance and service life. Especially for filters made of stainless steel, the importance of its structural design is self-evident. With its excellent corrosion resistance and high strength, stainless steel filter has become the preferred material for the filtration stage in water purification equipment.

[0003] In existing technologies, traditional stainless steel filter screens are mostly designed as a single unit. When the water purification equipment is running, the water flow impacts the filter screen surface with a certain pressure and speed. Over time, this inevitably damages the filter screen surface. Due to the integrated design, if any single area of ​​the filter screen is damaged, the entire filter screen can no longer perform its filtering function. In this case, the user has to replace the entire filter screen, which not only increases operating costs but also wastes resources. Secondly, traditional stainless steel filter screens typically use a straight-through design. When water flows through the filter screen, it passes through these straight holes in a straight line with almost no pause. This results in extremely short contact time between the water flow and the filter screen, making it insufficient to intercept impurities and microorganisms in the water. Many substances that should be filtered out enter subsequent water purification stages along with the straight-through water flow, thus reducing the overall filtration efficiency of the water purification equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a honeycomb stainless steel filter screen structure for water purification equipment, so as to solve the problems mentioned in the background art. Traditional stainless steel filter screens adopt an integrated design, which requires replacement of the whole screen after long-term water flow impact causes local damage, increasing costs. Secondly, traditional filter screens adopt a straight-through design, which results in short contact time for water flow, insufficient filtration, and reduced water purification effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a honeycomb stainless steel filter screen structure for water purification equipment, including an installation frame, an installation component and a limiting component installed on the installation frame, an outer frame of a filter plate installed on the installation frame, a filter plate fixedly installed on the outer frame of the filter plate, a sealing plate component installed on the installation frame, a sealing gasket fixedly installed on the installation frame, and a first through hole opened on the installation frame. The mounting components are used to fix the mounting frame to the working position. After the sealing plate assembly is installed on the mounting frame, the limiting components are used to restrict the movement of the sealing plate assembly. When the water flows through the filter plate, the filter plate filters the water flow.

[0006] In a preferred embodiment of this technical solution, the mounting frame is provided with a mounting groove that matches the outer frame of the filter plate, and the outer frame of the filter plate is mounted on the mounting groove.

[0007] Based on the preferred embodiment of this technical solution, the filter plate has through holes, and the through holes are S-shaped.

[0008] According to the preferred embodiment of this technical solution, the mounting components include a mounting side plate fixedly mounted on the mounting frame and mounting holes formed on the mounting side plate.

[0009] According to the preferred embodiment of this technical solution, the limiting component includes a side fixing seat fixedly installed on the mounting frame, a sliding block slidably connected to the side fixing seat, and a spring fixedly connected between the sliding block and the side fixing seat.

[0010] In the preferred embodiment of this technical solution, the side fixing seat has a limiting groove at the relative position of the sliding block, and the sliding block is slidably connected to the groove.

[0011] According to the preferred embodiment of this technical solution, the sealing plate assembly includes a sealing plate mounted on the mounting frame, a pull rod fixedly mounted on the sealing plate, and a second through hole opened on the sealing plate.

[0012] In the preferred embodiment of this technical solution, the sealing plate has a matching slot at the relative position of the sliding block, and the sliding block is engaged with the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The filter plate frame and filter plate adopt a modular design. When the filter plate in a single area is damaged, it is not necessary to replace the entire filter screen as in traditional integrated filters. Only the filter plate frame and filter plate in the corresponding damaged area need to be replaced. This greatly reduces the user's operating costs, avoids the cost of replacing the entire filter screen due to partial damage, and reduces unnecessary expenses.

[0014] 2. The filter plate features an S-shaped perforation design, which significantly extends the flow path of water within the filter plate compared to traditional straight-through perforations. When water enters the S-shaped perforation, it flows slowly along the curved channel. This process significantly increases the contact time between the water and the filter plate perforation wall, avoiding the insufficient filtration problems caused by excessively fast water flow and short contact time in traditional straight-through perforations.

[0017] 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.

[0018] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a honeycomb stainless steel filter screen structure for a water purification device, including a mounting frame 1, a mounting component and a limiting component mounted on the mounting frame 1, a filter plate outer frame 23 mounted on the mounting frame 1, a filter plate 24 fixedly mounted on the filter plate outer frame 23, a sealing plate component mounted on the mounting frame 1, a sealing gasket 21 fixedly mounted on the mounting frame 1, and a first through hole 22 opened on the mounting frame 1. The mounting components are used to fix the mounting frame 1 to the working position. After the sealing plate assembly is installed on the mounting frame 1, the limiting components are used to restrict the movement of the sealing plate assembly. When the water flows through the filter plate 24, the filter plate 24 filters the water flow. During assembly, the filter plate outer frame 23 and filter plate 24 are installed into the mounting groove on the mounting frame 1. After completion, the sealing plate assembly is installed on the mounting frame 1. At this time, the sealing plate assembly is limited by the limiting assembly, and the initial installation of the filter screen body is completed. In subsequent use, after aligning the mounting assembly with the external mounting point, it is connected to the external point by external bolts, etc., so that the mounting frame 1 is installed in the working position. When the water flows through, it first enters the inner side of the mounting frame 1 through the first through hole 22 on the mounting frame 1. At this time, the filter plate 24 filters the water flow. After filtration, the water flows through the sealing plate assembly. If the filter plate outer frame 23 and filter plate 24 in a single area are damaged, the limiting assembly is opened and the sealing plate assembly is removed. After opening the sealing plate assembly, the filter plate outer frame 23 and filter plate 24 at the corresponding position can be removed for disassembly and installation.

[0019] Please see Figure 3 A further solution based on this embodiment is as follows: the mounting frame 1 is provided with a mounting groove that is adapted to the filter plate outer frame 23. The filter plate outer frame 23 is installed on the mounting groove. The size and shape of the mounting groove match the filter plate outer frame 23. The quick positioning and stable installation are achieved through the fitting method. The disassembly and assembly process of the filter plate outer frame 23 is simplified during use, which facilitates daily maintenance and replacement. When the filter plate 24 in a certain area is damaged by impact, the filter plate outer frame 23 and filter plate 24 in that area can be replaced. At the same time, it is ensured that the filter plate outer frame 23 will not loosen or shift under the impact of water flow, thus ensuring the stability of the filtration effect.

[0020] Please see Figure 4 A further solution based on this embodiment is as follows: the filter plate 24 is provided with through holes, and the through holes are S-shaped. The S-shaped through holes extend the flow path of water in the filter plate 24, increase the contact time and contact area between the water and the filter plate 24, and improve the interception efficiency of impurities and microorganisms. Compared with the traditional straight-through filter screen with short contact time and insufficient filtration, it significantly improves the filtration effect and water quality of the water purification equipment.

[0021] Please see Figure 1 - Figure 2 A further solution based on this embodiment is as follows: the installation component includes a mounting side plate 25 fixedly mounted on the mounting frame 1 and mounting holes 26 opened on the mounting side plate 25. The filter screen structure is firmly fixed to the water purification equipment by bolts or other fasteners such as bolts through the mounting holes 26. The installation process is simple and quick, the connection is firm and reliable, and it can withstand water flow impact and equipment vibration, ensuring that the filter screen maintains a stable position during long-term use.

[0022] Please see Figure 2 , Figure 5 A further solution based on this embodiment is as follows: The limiting component includes a side fixing seat 31 fixedly installed on the mounting frame 1, a sliding block 32 slidably connected to the side fixing seat 31, and a spring 33 fixedly connected between the sliding block 32 and the side fixing seat 31. The spring 33 always applies an elastic force to the sliding block 32. When the sealing plate assembly is installed in place, the sliding block 32 clamps the sealing plate assembly under the action of the spring 33 to achieve limiting and fixing. No additional locking operation is required, making installation convenient. At the same time, it ensures the stability of the sealing plate assembly and facilitates later disassembly and maintenance.

[0023] Please see Figure 2 , Figure 5A further solution based on this embodiment is as follows: the side fixing seat 31 has a limiting groove at the relative position of the sliding block 32. The sliding block 32 is slidably connected to the groove. The groove limits the movement direction and travel range of the sliding block 32, ensuring that the sliding block 32 can only move in the preset direction, achieving precise engagement, improving the reliability and stability of the limiting component, preventing the sliding block 32 from misaligning and causing limiting failure, and further ensuring the installation quality of the sealing plate component. In use, by moving the sliding block 32 away from the sealing plate 27, the restriction on the sealing plate 27 can be released, and the sealing plate 27 can be removed.

[0024] Please see Figure 2 - Figure 3 A further solution based on this embodiment is as follows: the sealing plate assembly includes a sealing plate 27 installed on the mounting frame 1, a pull rod 28 fixedly installed on the sealing plate 27, and a second through hole 29 opened on the sealing plate 27. In use, after the filter plate outer frame 23 and the filter plate 24 are installed on the mounting frame 1, the movement of the filter plate outer frame 23 and the filter plate 24 can be suppressed and restricted by the sealing plate 27. The second through hole 29, together with the first through hole 22 and the through hole of the filter plate 24, constitute a complete water flow channel for water to flow through.

[0025] Please see Figure 5 A further solution based on this embodiment is as follows: the sealing plate 27 has a matching slot at the relative position of the sliding block 32, and the sliding block 32 is snapped into the slot. When the sealing plate 27 is installed in place, the sliding block 32 is embedded in the slot under the action of the spring 33. The sealing plate 27 is reliably limited through mechanical engagement, which enhances the stability of the sealing plate 27, effectively prevents the sealing plate 27 from loosening due to water flow impact, and facilitates quick disassembly during maintenance, thereby improving the overall reliability and service life of the equipment.

[0026] Working principle: During the filter assembly stage, the filter plate 24 and the filter plate outer frame 23 are first embedded into the pre-set fitting installation groove on the mounting frame 1 to quickly complete the positioning and initial fixation of the filter plate outer frame 23. After the filter plate outer frame 23 is installed, the sliding block 32 is moved to compress the spring 33, and then the sealing plate 27 is installed in the corresponding position of the mounting frame 1. At this time, the spring 33 on the side fixing seat 31 applies an elastic force to the sliding block 32, pushing the sliding block 32 to slide along the slide groove of the side fixing seat 31, so that the sliding block 32 is embedded in the slot, and the sealing plate 27 is limited and fixed through mechanical locking. After assembly, use the mounting holes 26 on the mounting side plate 25 on the mounting frame 1 to insert bolts and other external fasteners to firmly connect the mounting side plate 25 to the preset mounting point of the water purification equipment, thereby achieving stable fixation of the mounting frame 1 and the overall filter screen, ensuring that the filter screen can withstand the water flow impact and equipment vibration during the operation of the water purification equipment and remain in the preset working position for a long time. During the filtration stage of the filter screen operation, the water flows along a preset path. First, it enters the inner side of the mounting frame 1 through the first through hole 22 on the mounting frame 1, and then flows through the filter plate 24 on the outer frame 23 of the filter plate. The S-shaped through hole on the filter plate 24 extends the flow path of the water in the filter plate 24, greatly increasing the contact time and contact area between the water and the filter plate 24. After being filtered by the filter plate 24, the water continues to pass through the second through hole 29 on the sealing plate 27 of the sealing plate assembly to complete the filtration. During the later maintenance stage, if the filter plate 24 is partially damaged, the sliding block 32 can be manually moved away from the sealing plate 27 along the slide groove and disengaged from the slot. After the sealing plate 27 is released from its limiting position, it can be easily removed by the pull rod 28 on the sealing plate 27. Then, the filter plate frame 23 corresponding to the damaged filter plate 24 can be removed from the installation slot, and a new filter plate frame 23 and filter plate 24 can be replaced. Then, the sealing plate 27 can be installed in reverse order. The sliding block 32 will automatically embed into the slot and reposition under the action of the spring 33, realizing the quick replacement of local components.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
