Description

Technical Field

[0001] This utility model relates to the field of filtration units, specifically a modular combined artificial wetland filtration unit. Background Technology

[0002] Modular constructed wetland filtration units are a wastewater treatment technology based on natural ecological principles. By breaking down the constructed wetland system into standardized, flexibly assembled functional modules, it achieves efficient water purification. Its core lies in transforming the complex structure of traditional constructed wetlands into independent units that can be prefabricated in the factory and assembled on-site.

[0003] Existing technologies face challenges such as difficulty in assembling and positioning large-area devices, loose fixing, complex maintenance, weak protection, poor area adaptability, high cost, and high operational threshold. This technology aims to ensure structural stability and efficient operation and maintenance, and adapt to various scenario requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a modular and combined artificial wetland filter unit, which has the advantages of precise and quick splicing, firm fixation and resistance to external forces, tool-free installation and disassembly, high efficiency and durable components, comprehensive protection without blind spots, adaptability to multiple scenarios, flexible modular expansion, low cost and easy promotion, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A modular, combined constructed wetland filtration unit includes a fixed shell. A first slot is formed through one side of the fixed shell. Second slots are formed on both the upper and lower sides of the inner wall of the first slot. An upper filter plate is fixed to the inner wall of the second slot located above the first slot. A middle filter plate is fixed to the lower end of the upper filter plate. A lower filter plate is fixed to the lower end of the middle filter plate. The lower end of the lower filter plate is fixed to the inner wall of the second slot at the lower end of the first slot. A left limiting block is fixed to one side of the upper and lower filter plates. A right limiting block is fixed to the other side of the middle filter plate. Protective mechanisms are provided on both sides of the fixed shell.

[0007] Preferably, the protection mechanism includes a fixed plate slidably mounted on the lower end of the left limiting block. The fixed plate has a third slot on both sides. One end of a spring is fixedly connected to the inner wall of the third slot, and a sliding block is fixedly connected to the other end of the spring. A fourth slot is opened on both sides of the inner wall of the first slot. The sliding block and the fourth slot correspond to each other. A protective plate is fixedly connected to one side of the fixed plate. A protective shell is slidably mounted on the side wall of the right limiting block. The protective shell has a concave cross-section, and the side wall of the right limiting block fits against the inner wall of the protective shell.

[0008] It is worth noting that by squeezing the two sliding blocks, the sliding blocks squeeze the spring. When the sliding blocks are squeezed into the third slot, they push the protective plate to slide the fixed plate into the middle of the two left limit blocks inside the protective shell.

[0009] Preferably, the upper end of the fixed shell has multiple first screw holes through it on the side near the left limiting block; the upper end of the left limiting block has multiple second screw holes through it, and the multiple first screw holes and multiple second screw holes correspond one-to-one, with a first bolt connecting the first screw holes and the second screw holes.

[0010] It is worth noting that the left limiting block and the fixing shell are fixed together by passing the first bolt through the first screw hole and the second screw hole.

[0011] Preferably, the upper end of the right limiting block is provided with multiple third screw holes, and the upper end of the protective shell is provided with multiple fourth screw holes. The multiple third screw holes and the multiple fourth screw holes correspond one-to-one, and the second bolt connects the third screw holes and the fourth screw holes.

[0012] It is worth noting that the protective shell is fixed to the surface of the right limit block by the second bolt. The protective shell is fixed by the bolt. When the middle filter layer needs to be cleaned, the protective shell can be removed and reinstalled after cleaning to restore the protective function.

[0013] Preferably, the side of the two sliding blocks that are far apart has an arc structure, and the side of the two sliding blocks that are far apart is located on the inner wall of the fourth slot.

[0014] It is worth noting that the arc surface reduces the frictional resistance between the sliding block and the fourth slot, preventing jamming during disassembly and assembly, while also reducing scratches on the inner wall of the slot and extending its service life.

[0015] Preferably, the fixing plate is located in the middle of the two left limiting blocks, and the sides of the two left limiting blocks that are close to each other are respectively attached to the two sides of the fixing plate.

[0016] It is worth noting that the two left limiting blocks clamp the fixing plate from the left and right, restricting the lateral movement of the fixing plate and ensuring that the protective plate is always aligned with the left side of the filter layer, thus avoiding blind spots in protection due to the offset of the fixing plate.

[0017] Preferably, the upper and lower ends of the fixed shell are provided with multiple filter holes.

[0018] It is worth noting that the water flows through multiple filter holes to reach the upper filter plate, thus purifying the water.

[0019] Preferably, the length of the right limiting block is the same as the length of the fixing plate, the height of the right limiting block is the same as the height of the fixing plate, the width of the right limiting block is the same as the width of the fixing plate, and the multiple first screw holes and multiple third screw holes correspond one-to-one.

[0020] It is worth noting that when the area is too large and multiple devices need to be spliced ​​together, the right limit block of the first device can be slidably installed between the two left limit blocks of the second device, and the first device and the second device can be fixed together by the first bolt.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model uses a sliding embedding design where the right limiting block is embedded in the gap between the left limiting block to form a natural positioning guide. The inner side of the left limiting block serves as a reference surface, allowing the edges of the fixed shells of the two devices to be aligned without repeated calibration.

[0023] 2. The one-to-one correspondence of the first screw hole, the second screw hole, and the third screw hole, together with the through fixation of the first bolt, forms a triple fixing structure with the fixed shell bearing, the limiting block engaging, and the bolt locking. Pressing the sliding block causes the spring to contract, and after pushing it into the fixed shell, the spring returns to its original position, allowing the sliding block to engage in the fourth slot, making installation or disassembly convenient.

[0024] 3. The modular design allows for installation based on available space, making it suitable for various locations and easy to replace, thus reducing production costs. Attached Figure Description

[0031] 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.

[0032] To address the challenges of difficult splicing and positioning, loose fixing, cumbersome maintenance, weak protection, poor area adaptability, high cost, and high operational barriers in existing technologies for large-area devices, and to ensure structural stability, efficient operation and maintenance, and adaptability to various scenarios, the following technical solution is proposed. Please refer to [link / reference]. Figure 1-5 ;

[0033] A modular, combined constructed wetland filtration unit includes a fixed shell 1. A first slot 2 is formed through one side of the fixed shell 1. Second slots 3 are formed on both the upper and lower sides of the inner wall of the first slot 2. An upper filter plate 4 is fixedly connected to the inner wall of the second slot 3 located above the first slot 2. A middle filter plate 5 is fixedly connected to the lower end of the upper filter plate 4. A lower filter plate 6 is fixedly connected to the lower end of the middle filter plate 5. The lower end of the lower filter plate 6 is fixedly connected to the inner wall of the second slot 3 at the lower end of the first slot 2. A left limiting block 7 is fixed to one side of the filter plate 4 and the lower filter plate 6, and a right limiting block 8 is fixed to the other side of the middle filter plate 5. Protective mechanisms 9 are provided on both sides of the fixed shell 1. Multiple first screw holes are opened through the upper end of the fixed shell 1 near the left limiting block 7. Multiple second screw holes are opened through the upper end of the left limiting block 7. The multiple first screw holes and multiple second screw holes correspond one-to-one. The first bolt connects the first screw holes and the second screw holes. Multiple filter holes are opened through both the upper and lower ends of the fixed shell 1.

[0034] The protective mechanism 9 includes a fixed plate 91 slidably mounted on the lower end of the left limiting block 7. The fixed plate 91 has third slots 92 on both sides. One end of a spring 93 is fixedly connected to the inner wall of the third slot 92, and a sliding block 94 is fixedly connected to the other end of the spring 93. Fourth slots 95 are opened on both sides of the inner wall of the first slot 2, with the sliding block 94 corresponding to the fourth slots 95. A protective plate 96 is fixedly connected to one side of the fixed plate 91. A protective shell 97 is slidably mounted on the side wall of the right limiting block 8. The protective shell 97 has a concave cross-section, and the side wall of the right limiting block 8 fits against the inner wall of the protective shell 97. Multiple third screws are threaded through the upper end of the right limiting block 8. The upper end of the protective shell 97 has multiple fourth screw holes, and multiple third screw holes and multiple fourth screw holes correspond one-to-one. The second bolt connects the third screw holes and the fourth screw holes. The side of the two sliding blocks 94 that is far apart has an arc structure. The side of the two sliding blocks 94 that is far apart is located on the inner wall of the fourth slot 95. The fixing plate 91 is located in the middle of the two left limiting blocks 7. The side of the two left limiting blocks 7 that is close to each other is respectively attached to the two sides of the fixing plate 91. The length of the right limiting block 8 is the same as the length of the fixing plate 91, the height of the right limiting block 8 is the same as the height of the fixing plate 91, and the width of the right limiting block 8 is the same as the width of the fixing plate 91. Multiple first screw holes and multiple third screw holes correspond one-to-one.

[0035] Working principle: First, align the right limiting block 8 of the first device with the gap between the two left limiting blocks 7 of the second device, and slide it in along the inner side of the left limiting block 7 to align the edges of the fixing shell 1 of the two devices. At this time, the third screw hole on the right limiting block 8 of the first device and the second screw hole on the left limiting block 7 of the second device will correspond one-to-one with the first screw hole on the fixing shell 1. Then, screw the first bolt into the aligned first screw hole, second screw hole and third screw hole in sequence and tighten it. Through the bearing of the fixing shell 1 and the mutual locking of the left limiting block 7 and the right limiting block 8, the two devices are stably spliced. Repeat this operation to complete the large-area laying of multiple sets of devices, ensuring that the overall structure is not loose or displaced. When installing the protective mechanism 9, first press the sliding blocks 94 on both sides of the fixing plate 91 with both hands to squeeze the spring 93 into the third slot 92. Then, align the fixing plate 91 with the mounting opening of the fixing shell 1 and slowly push it in along the side wall of the left limiting block 7 until the fixing plate 91 is completely attached to the inner wall of the fixing shell 1. At this time, the third slot 92 on the fixing plate 91 will be precisely aligned with the fourth slot 95 on the inner wall of the fixing shell 1. After the spring 93 loses the external pressure, it returns to its original shape, pushing the sliding block 94 outward and into the fourth slot 95, completing the quick fixing of the fixing plate 91 and achieving protection for the left side of the device. The protection mechanism 9 needs to be removed. Simply grasp the left protection plate 96 and pull it outward: Since the side of the sliding block 94 away from the spring 93 is an arc surface, when pulled, the arc surface will be squeezed against the inner wall of the fourth slot 95, forcing the sliding block 94 to... 4. The sliding block 94 retracts into the third slot 92; after the sliding block 94 completely disengages from the fourth slot 95 and retracts into the third slot 92, the fixing plate 91 and the protective plate 96 can be smoothly pulled out from the fixing shell 1, completing the disassembly of the single-sided protection mechanism 9. Take the protective shell 97 and attach its concave surface to the side wall of the right limit block 8 of the rightmost device, so that the fourth screw hole on the protective shell 97 is aligned with the third screw hole on the right limit block 8; then screw the second bolt into the aligned screw hole and tighten it, so that the protective shell 97 is firmly fixed on the right limit block 8. Finally, the protective plate 96 on the left and the protective shell 97 on the right form protection on both sides of the entire large-area laying device.
