Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a modular wastewater treatment device that is easy to maintain. Background Technology

[0002] In the design and application of wastewater treatment equipment, ease of maintenance is a crucial factor affecting its long-term stable operation. Currently, most wastewater treatment equipment on the market adopts an integrated structural design. While this can meet basic treatment needs, its compact internal component layout necessitates the disassembly of a large amount of the structure during maintenance or component replacement, increasing operational difficulty and time costs. Furthermore, these devices lack modular design, making it difficult to flexibly adjust the number or function of treatment units according to actual needs.

[0003] Therefore, we have made improvements to this and proposed a modular wastewater treatment device that is easy to maintain. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing sewage treatment equipment in terms of ease of maintenance and modular design, specifically the problems of compact internal component layout, complex disassembly, and poor module independence.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a modular wastewater treatment device that is easy to maintain. The device includes a treatment unit module and a support frame module. The treatment unit module is detachably connected to the support frame module via a connecting mechanism. The connecting mechanism includes a positioning component and a locking component. The positioning component enables rapid alignment of the treatment unit module on the support frame module, while the locking component secures the position of the treatment unit module, ensuring its stability during operation. The support frame module has slide rails on both sides, and sliders are installed within these rails. The sliders are fixedly connected to the bottom of the treatment unit module, allowing the treatment unit module to be installed or disassembled by moving along the slide rails using the sliders.

[0006] The processing unit module includes a filtration unit, a sedimentation unit, and a disinfection unit. The filtration unit is located at the front end of the processing unit module, the sedimentation unit is located at the rear end of the filtration unit, and the disinfection unit is located at the rear end of the sedimentation unit. The units are connected by a flexible connecting tube, and each end of the flexible connecting tube is provided with a quick connector. The quick connector is fixedly connected to the interface of each unit by a rotating buckle. The filtration unit has a filter screen assembly inside, which is fixed to the inner wall of the filtration unit by a threaded connection. The top of the filter screen assembly is provided with a handle for easy manual removal by the user for cleaning or replacement.

[0007] The support frame module includes a base and columns. The base is a rectangular frame structure. The columns are vertically fixed to the four corners of the base. The outer side of the columns is provided with reinforcing ribs, which are welded to the base. The slide rail is fixed to the inner side of the columns, and both ends of the slide rail are provided with limiting baffles. The limiting baffles are fixed to the slide rail with bolts to prevent the slider from disengaging from the slide rail.

[0008] The positioning component includes a positioning pin and a positioning hole. The positioning pin is fixed to the bottom of the processing unit module, and the positioning hole is opened at the top of the slide rail. The positioning pin and the positioning hole work together to ensure that the processing unit module can be accurately aligned during installation. The locking component includes a locking screw and a locking block. The locking screw passes through the locking block and is threaded to the side of the slide rail. The inner side of the locking block is provided with a rubber pad, which contacts the outer side of the slider. By tightening the locking screw, the locking block presses the slider, thereby fixing the position of the processing unit module.

[0009] The flexible connecting tube has an expansion joint in the middle, which is made of corrugated pipe and can adapt to the displacement generated during the installation or disassembly of the processing unit module; the quick connector has a sealing ring on the outside, which is made of silicone material, and the sealing connection of the flexible connecting tube is achieved by the tight fit between the sealing ring and the interface.

[0010] The filter assembly includes a frame and a filter. The frame has a rectangular structure, and the filter is fixed inside the frame by an embedded installation. The frame has protrusions on its four edges, which form an interference fit with the inner wall of the filter unit to ensure that the filter assembly will not loosen after installation. The handle is fixed at the top center of the frame, and the outer surface of the handle has anti-slip texture for easy gripping and operation by the user.

[0011] The base has leveling feet at its bottom, which are fixed to the four corners of the base by threaded connection. The bottom of the leveling feet has rubber pads that are in contact with the ground. The height of the base can be adjusted by rotating the leveling feet to ensure that the support frame module remains level on uneven ground.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this application, a connecting mechanism enables rapid installation and disassembly between the treatment unit module and the support frame module. Users simply push the treatment unit module along the slide rail, align it with the positioning pin and positioning hole, and then secure it with the locking assembly to complete the installation. Simultaneously, the use of flexible connecting pipes and quick couplings allows for flexible connection between the treatment units, avoiding the disassembly difficulties associated with traditional fasteners or welded structures. Furthermore, the filter assembly employs a combination of threaded connection and embedded installation, further simplifying maintenance. Users can directly lift the filter assembly for cleaning or replacement using the handle. The overall structural design is reasonable and highly modular, not only reducing equipment maintenance costs but also improving operational stability, thus solving the problems of inconvenient maintenance and insufficient modular design in existing wastewater treatment equipment.

[0021] This utility model provides a modular sewage treatment device that is easy to maintain, the structure and operation of which are as follows: Figures 1 to 5As shown in the figure. The device includes a processing unit module 1 and a support frame module 2, which are detachably connected by a connecting mechanism. The processing unit module 1 consists of a filtration unit 5, a sedimentation unit 6, and a disinfection unit 7. The units are connected by flexible connecting pipes 8, with quick connectors 9 at both ends of the flexible connecting pipes 8. The support frame module 2 includes a base 22 and columns 23. The columns 23 are vertically fixed to the four corners of the base 22, and slide rails 3 are provided on the inner side of the columns 23. Slider blocks 4 are installed on the slide rails 3 and are fixedly connected to the bottom of the processing unit module 1. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the processing unit module 1 is installed or disassembled by moving the slider 4 along the slide rail 3. The slide rail 3 is fixed to the inner side of the column 23, and limit baffles are provided at both ends of the slide rail 3 to prevent the slider 4 from disengaging from the slide rail 3. The limit baffles are fixed to the slide rail 3 with bolts to ensure its stability. The slider 4 is fixedly connected to the bottom of the processing unit module 1 with bolts, so that the processing unit module 1 can move smoothly along the slide rail 3. In order to achieve quick alignment of the processing unit module 1, a positioning component is provided in the connecting mechanism, including a positioning pin 12 and a positioning hole 13. The positioning pin 12 is fixed to the bottom of the processing unit module 1, and the positioning hole 13 is opened at the top of the slide rail 3. When the processing unit module 1 is pushed in along the slide rail 3, the positioning pin 12 is inserted into the positioning hole 13 to complete the alignment. Then, the position of the processing unit module 1 is fixed by a locking component, which includes a locking screw 14 and a locking block 15. The locking screw 14 passes through the locking block 15 and is threaded to the side of the slide rail 3. The inner side of the locking block 15 is provided with a rubber pad 16. When the locking screw 14 is tightened, the locking block 15 presses against the slider 4, thereby fixing the processing unit module 1 to the support frame module 2. This design ensures that the processing unit module 1 remains stable during operation, while also facilitating quick disassembly and installation by the user.

[0023] The internal structure of processing unit module 1 is as follows: Figure 2As shown, it includes a filtration unit 5, a sedimentation unit 6, and a disinfection unit 7. The filtration unit 5 is located at the front end of the processing unit module 1, the sedimentation unit 6 is located at the rear end of the filtration unit 5, and the disinfection unit 7 is located at the rear end of the sedimentation unit 6. The units are connected by a flexible connecting pipe 8, with quick connectors 9 at both ends. The quick connectors 9 are fixedly connected to the interfaces of each unit via rotating snaps, avoiding the disassembly difficulties caused by traditional fasteners or welded structures. An expansion joint 17, made of corrugated pipe, is located in the middle of the flexible connecting pipe 8 to accommodate displacement during installation or disassembly of the processing unit module 1. A sealing ring 18, made of silicone, is located on the outer side of the quick connector 9. The tight fit between the sealing ring 18 and the interface ensures a sealed connection of the flexible connecting pipe 8. This design not only improves the flexibility of the connection but also guarantees the sealing performance at the connection point.

[0024] like Figure 4 As shown, the filter unit 5 contains a filter assembly 10, which is fixed to the inner wall of the filter unit 5 by a threaded connection. The filter assembly 10 includes a frame 19 and a filter 20. The frame 19 has a rectangular structure, and the filter 20 is fixed inside the frame 19 by an embedded installation. The frame 19 has protrusions around its edges, which form an interference fit with the inner wall of the filter unit 5 to ensure that the filter assembly 10 will not loosen after installation. The top of the filter assembly 10 has a handle 11, which is fixed to the center of the top of the frame 19. The outer surface of the handle 11 has anti-slip textures, making it easy for users to manually remove it for cleaning or replacement. The design of the filter assembly 10 simplifies maintenance operations; users can simply remove the filter assembly 10 from the filter unit 5 using the handle 11 to complete cleaning or replacement.

[0025] The structure of support frame module 2 is as follows Figure 5 As shown, it includes a base 22 and columns 23. The base 22 is a rectangular frame structure, and the columns 23 are vertically fixed to the four corners of the base 22. Reinforcing ribs 24 are provided on the outer side of the columns 23, and the reinforcing ribs 24 are welded to the base 22, enhancing the overall strength of the support frame module 2. A slide rail 3 is fixed to the inner side of the columns 23 to support the slider 4 of the processing unit module 1. Furthermore, the bottom of the base 22 is provided with leveling feet 21, which are fixed to the four corners of the base 22 by threaded connections. Rubber pads are provided on the bottom of the leveling feet 21. By rotating the leveling feet 21 to adjust the height of the base 22, the support frame module 2 can be kept level on uneven ground. This design improves the adaptability of the equipment, enabling it to operate stably under different ground conditions.

[0026] In actual operation, wastewater first flows into filtration unit 5, where it undergoes preliminary filtration by filter assembly 10 to remove larger particulate impurities before entering sedimentation unit 6 for further solid-liquid separation. The settled wastewater then flows into disinfection unit 7, where it is disinfected to meet discharge standards. During this process, the design of flexible connecting pipes 8 and quick connectors 9 allows for more flexible connections between treatment units, enabling users to quickly disassemble or replace any unit in treatment unit module 1 as needed. For example, when filter assembly 10 needs cleaning, the user can remove it from filtration unit 5 using handle 11, clean it, and then reinstall it. Furthermore, if a treatment unit malfunctions, the user can quickly disassemble the entire treatment unit module 1 using slide rails 3 and sliders 4 for repair or replacement.

[0027] The modular design and convenient maintenance of this invention significantly reduce equipment maintenance costs while improving operational stability. The use of the slide rail 3, slider 4, positioning pin 12, positioning hole 13, locking screw 14, and locking block 15 enables rapid installation and disassembly of the treatment unit module 1. The design of the flexible connecting pipe 8 and quick connector 9 further enhances the equipment's flexibility and sealing, solving the problems of inconvenient maintenance and insufficient modular design in existing wastewater treatment equipment.

[0028] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0029] First, the support frame module 2 is placed at the installation site of the sewage treatment equipment. The four corners of the base 22 are height-adjustable using leveling feet 21. Rotating the leveling feet 21 adapts to uneven ground, ensuring the base 22 remains level. Rubber pads provide anti-slip properties upon contact with the ground, while also preventing damage to the surface. After leveling, the column 23 is welded to the base 22 via reinforcing ribs 24, enhancing the overall structural stability.

[0030] Subsequently, the processing unit module 1 is pushed into the support frame module 2 along the slide rail 3 via the slider 4. During the pushing process, the positioning pin 12 engages with the positioning hole 13 on the top of the slide rail 3 to ensure that the processing unit module 1 can be quickly and accurately aligned. Once the positioning pin 12 is fully inserted into the positioning hole 13, the locking assembly begins to function. The user tightens the locking screw 14, causing the locking block 15 to press against the slider 4, and the rubber pad 16 to make tight contact with the outside of the slider 4, thereby fixing the position of the processing unit module 1. This operation simplifies the installation process while ensuring the stability of the processing unit module 1 during operation.

[0031] After wastewater enters the equipment, it first flows into filter unit 5. As the wastewater passes through filter unit 5, the filter screen assembly 10 performs preliminary filtration of larger particles. The filter screen assembly 10 is fixed to the inner wall of filter unit 5 via an interference fit with frame 19, and a handle 11 on its top facilitates manual removal by the user. When the filter screen assembly 10 needs cleaning, the user simply grasps the handle 11, applies force using the anti-slip texture, and removes the filter screen assembly 10 from filter unit 5. After cleaning, it can be reinstalled. This design significantly reduces maintenance difficulty and time costs.

[0032] Filtered wastewater flows into sedimentation unit 6 through flexible connecting pipe 8. Both ends of flexible connecting pipe 8 are fixedly connected to the interfaces of filter unit 5 and sedimentation unit 6 via quick connectors 9. Quick connectors 9 use a rotary snap-fit ​​method, avoiding the disassembly difficulties associated with traditional fasteners or welded structures. During installation or disassembly, expansion joint 17 absorbs displacement changes through its bellows design, ensuring connection flexibility. Sealing ring 18, made of silicone material, fits tightly to the interface, ensuring a tight seal at the connection and preventing wastewater leakage.

[0033] After sedimentation, the wastewater continues to flow into the disinfection unit 7 for final treatment through the flexible connecting pipe 8. During this process, if a treatment unit malfunctions, the user can quickly disassemble the entire treatment unit module 1 using the slide rail 3 and slider 4. Specifically, loosen the locking screw 14, release the clamping force of the locking block 15 on the slider 4, and then pull the treatment unit module 1 out along the slide rail 3. This modular design allows each treatment unit to be replaced or repaired independently without disassembling the entire equipment, significantly improving maintenance efficiency.

[0034] Furthermore, the rectangular frame structure of the support frame module 2 and the design of the reinforcing ribs 24 further enhance the overall strength of the equipment, enabling it to remain stable under high-load operating conditions. The limiting baffles at both ends of the slide rail 3 are fixed with bolts to prevent the slider 4 from detaching from the slide rail 3 during movement, ensuring the safety and reliability of the equipment.

[0035] In summary, this utility model achieves rapid installation and disassembly of the treatment unit module 1 through the synergistic action of the slide rail 3, slider 4, positioning pin 12, positioning hole 13, locking screw 14, and locking block 15; the design of the flexible connecting pipe 8 and quick connector 9 enhances the flexibility and sealing of the equipment; and the handle 11 and threaded connection design of the filter assembly 10 simplify maintenance operations. These technical means collectively solve the problems of inconvenient maintenance and insufficient modular design in existing sewage treatment equipment, significantly reducing equipment maintenance costs while improving operational stability.
