[0034] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0035] The zero-carbon intelligent prefabricated integrated water treatment device of the present invention is mainly used for the purification treatment of sewage, including multiple water treatment units 1, multiple series pipes 2, intermediate platform 3 and two ladders 4.

[0036] The prefabricated integrated water treatment device has a rectangular structure. Its main frame is assembled from multiple water treatment units 1. Each water treatment unit 1 is equipped with one or more functional modules, such as a filtration module, a sedimentation module, a flocculation module, and a disinfection module. Multiple water treatment units 1 are connected in series through a series pipe 2, so that the prefabricated integrated water treatment device covers all the processes of sewage treatment. When water flows through each water treatment unit 1 in sequence, the purification effect can be achieved.

[0037] Prefabricated integrated water treatment units are a modern water treatment solution that modularly designs and prefabricates water treatment processes and equipment in a factory, and then transports them to the site for rapid installation. This not only shortens the construction cycle of the unit, but also improves its transportation convenience and adaptability to the installation environment.

[0038] like Figure 7 As shown, the water treatment unit 1 is a rectangular box structure. Each water treatment unit 1 is provided with multiple upper interfaces 101 and multiple lower interfaces 102. After the water treatment unit 1 is placed in a designated position, the series pipe 2 is connected to the corresponding upper interface 101 and lower interface 102, while the excess upper interfaces 101 and lower interfaces 102 are blocked.

[0039] As the prefabricated integrated water treatment device is used for a longer period of time, leakage problems are prone to occur at the connection points between the upper interface 101 and the lower interface 102 and the series pipe 2. In order to conduct regular inspections of each upper interface 101 and lower interface 102, such as... Figure 1 As shown, multiple water treatment units 1 are arranged to form an inspection channel 100, with at least one upper interface 101 and at least one lower interface 102 on each water treatment unit 1 facing the inspection channel 100. The series pipe 2 is connected only to the upper interface 101 and lower interface 102 on the water treatment unit 1 that face the inspection channel 100. By walking along the inspection channel 100 once, the inspection personnel can check all the upper interfaces 101 and lower interfaces 102 connected to the series pipe 2.

[0040] The inspection channel 100 is preferably U-shaped, with its outlet and inlet on the same side of the prefabricated integrated water treatment device, which can effectively improve the work efficiency of inspection personnel.

[0041] Meanwhile, the water treatment unit 1 is filled with water that needs to be purified. Multiple water treatment units 1 located on the periphery of the prefabricated integrated water treatment device form a heat insulation barrier, which can keep the temperature in the inspection channel 100 stable. Setting the series pipe 2 in the inspection channel 100 in the prefabricated integrated water treatment device can effectively improve the service life of the connection position between the series pipe 2 and the upper interface 101 and the lower interface 102.

[0042] The water treatment unit 1 is quite tall, which makes the upper interface 101 too high for inspection and maintenance. Therefore, the intermediate platform 3 is fixedly installed in the inspection channel 100. The intermediate platform 3 is located between the upper interface 101 and the lower interface 102. The ladder 4 is fixedly installed on the intermediate platform 3, with the two ladders 4 located at opposite ends of the inspection channel 100. When the inspection personnel walk on the ground of the inspection channel 100, they can inspect the position of the lower interface 102, and when the inspection personnel walk on the intermediate platform 3, they can inspect the position of the upper interface 101.

[0043] In a preferred embodiment, multiple water treatment units 1 are abutted together and combined to form two end modules 110, a side module 120, and a middle module 130, such as... Figure 1 As shown, two end modules 110 are arranged in parallel and spaced apart. The two ends of the side module 120 abut against one end of each of the two end modules 110. The middle module 130 is spaced between the two end modules 110. One end of the middle module 130 is flush with one end of the end module 110, and the other end of the middle module 130 is spaced apart from the side module 120. By arranging the end modules 110, side modules 120 and middle module 130 in this way, a U-shaped inspection channel 100 can be formed within the prefabricated integrated water treatment device.

[0044] Preferably, the length of the water treatment unit 1 is greater than the width of the water treatment unit 1, such as... Figure 3 As shown, the length direction of the water treatment unit 1 located above the side module 120 is perpendicular to the length direction of the two adjacent water treatment units 1. These three water treatment units 1 form an installation area 103 between the side module 120 and the end module 110. One side of the installation area 103 is connected to the inspection channel 100, which can be inspected and maintained by inspection personnel. The other three sides of the installation area 103 are water treatment units 1. Therefore, multiple water treatment units 1 can be installed in the installation area 103 to provide the necessary supply devices, such as dosing devices, aeration devices, and heating devices, so that the internal space of the device can be better optimized.

[0045] Alternatively, the length directions of two adjacent water treatment units 1 located in the middle of the side module 120 can be perpendicular, forming an installation area 103 within the side module 120. Similarly, installation areas 103 can also be provided in the end module 110 and the middle module 130. This not only allows multiple water treatment units 1 to share a single supply device, which is beneficial for optimizing the overall layout of the prefabricated integrated water treatment device, but also allows the middle platform 3 to extend into the installation area 103, improving the anti-slip capability of the middle platform 3.

[0046] like Figure 2 As shown, it is preferable to position a portion of the series tube 2 on the top or bottom side of the intermediate platform 3, and to fix the portion of the series tube 2 to the intermediate platform 3, thereby improving the fixation strength of the series tube 2.

[0047] To reduce the overall space occupied by the prefabricated integrated water treatment device and ensure the heat insulation effect of the peripheral water treatment unit 1, it is preferable to make adjacent water treatment units 1 abut against each other. If the two abutting water treatment units 1 are connected by a series pipe 2, it will result in a large number of series pipes 2. Therefore, the structure of the water treatment unit 1 has been improved.

[0048] like Figure 4As shown, the water treatment unit 1 includes a housing 11, a connecting pipe 12, a limiting plate 13, and a movable pipe 14. A hidden groove 104 is provided on the periphery of the housing 11. The connecting pipe 12 is fixedly installed in the hidden groove 104 and communicates with the interior of the housing 11. The limiting plate 13 is fixedly installed on the connecting pipe 12. The movable pipe 14 is sealed and slidably installed on the connecting pipe 12. When two water treatment units 1 are spaced apart, the movable pipes 14 in the two water treatment units 1 slide out of the hidden groove 104 and are connected by a connecting component. When the two water treatment units 1 are in contact, the two movable pipes 14 slide back into their respective hidden grooves 104 and abut against the limiting plate 13, thereby achieving communication between the two in contact water treatment units 1 and reducing the amount of serial pipe 2 required.

[0049] When two water treatment units 1 are in contact with each other, the two hidden slots 104 at corresponding positions enclose a closed space, which can not only isolate and protect the movable pipe 14 and the connecting components, but also form a second sealing structure to ensure the connection between the two adjacent water treatment units 1.

[0050] To improve the sealing effect of two adjacent water treatment units 1, a sealing ring can be set on the side of the limiting plate 13 near the movable pipe 14. When the movable pipe 14 abuts against the sealing ring on the limiting plate 13, a better sealing effect can be achieved. Similarly, a corresponding sealing ring can also be set at the outer edge of the hidden groove 104 to achieve the same sealing effect.

[0051] The aforementioned connecting components can be structures such as flanges or clamps. However, as the prefabricated integrated water treatment device is used for an extended period, some water treatment units 1 will be damaged and need to be replaced. If connecting components with structures such as flanges or clamps are used, it is not easy to replace a single water treatment unit 1. Therefore, this invention proposes two specific structures for the connecting components:

[0052] The first structure is Figure 5 The bent tube 15 shown, when one end of the movable tube 14 abuts against the limiting plate 13, the other end of the movable tube 14 does not extend out of the hidden groove 104 and is spaced apart from the periphery of the box body 11. The bent tube 15 includes a middle tube 151 and two end tubes 152. The two end tubes 152 are arranged in parallel. The two end tubes 152 are respectively rotatably arranged at both ends of the middle tube 151, and the two end tubes 152 are respectively sealed and fixed on two adjacent movable tubes 14.

[0053] When the two water treatment units 1 are spaced apart, the two movable pipes 14 slide out of the corresponding hidden grooves 104, and then the two end pipes 152 are fixed on the two movable pipes 14 respectively; when the two water treatment units 1 are in contact, the two movable pipes 14 slide into the corresponding hidden grooves 104 respectively and abut against the limiting plate 13 to realize the connection between the two water treatment units 1.

[0054] like Figure 5 As shown, since the end pipe 152 is rotatably connected to the middle pipe 151, the water treatment unit 1 on the left can rotate around the axis of the movable pipe 14 on the right. That is, when the water treatment unit 1 on the left is lifted and moved by equipment such as a forklift, the two water treatment units 1 can be staggered by a certain distance, so that the hidden groove 104 is connected to the outside. Thus, tools can be inserted into the hidden groove 104 to disassemble the bend pipe 15, thereby realizing the replacement of a single water treatment unit 1.

[0055] The second structure is Figures 6-9 The fixture 16 shown includes a frame 161, a limiting rod 162, a connecting bolt 163, and a connecting rod 164. The frame 161 is slidably mounted on the movable tube 14, and the end of the frame 161 away from the limiting plate 13 is flush with the movable tube 14. A slot 105 is provided on the movable tube 14. The limiting rod 162 is rotatably mounted on the frame 161 and engages with the slot 105, so that the frame 161 and the movable tube 14 remain relatively fixed.

[0056] Connecting bolts 163 are threaded onto frame 161, and connecting rods 164 are fixedly mounted on connecting bolts 163. When the two water treatment units 1 are spaced apart, the two movable pipes 14 slide out of their corresponding hidden slots 104, aligning the two frames 161. Then, the connecting bolts 163 and connecting rods 164 on the two frames 161 are used to fix the frames 161 on the two movable pipes 14, making the end faces of the two movable pipes 14 connected. When one end of the movable pipe 14 abuts against the limiting plate 13, the other end of the movable pipe 14 can be flush with the periphery of the housing 11. Therefore, when the two water treatment units 1 are in contact, as... Figure 6 As shown, the two movable tubes 14 slide into the corresponding hidden grooves 104 and abut against the limiting plate 13, and the ends of the two movable tubes 14 are aligned to achieve the connection between the two water treatment units 1.

[0057] like Figure 9As shown, one end of the limiting rod 162 is rotatably mounted on the top side inside the frame 161, and the other end of the limiting rod 162 is provided with a cylindrical limiting protrusion 106. The axis of the limiting protrusion 106 is parallel to the axis of the movable tube 14, that is, the end plane of the limiting protrusion 106 abuts against the side wall of the slot 105, so that the frame 161 and the movable tube 14 will not move relative to each other in the axial direction of the limiting protrusion 106, thereby enabling the frame 161 to drive the movable tube 14 to move along the axial direction of the movable tube 14, and enabling the connection of the two frames 161 to lock the two movable tubes 14.

[0058] The periphery of the limiting protrusion 106 is arc-shaped, such as Figure 9 As shown, when the movable tube 14 moves left or right, the limiting rod 162 will rotate, thereby causing the limiting protrusion 106 to disengage from the slot 105; as Figure 6 As shown, when the left water treatment unit 1 is slid down, the left movable pipe 14 and the two frames 161 will slide relative to each other, thereby causing the two movable pipes 14 and the two hidden slots 104 to be misaligned, and allowing the hidden slots 104 to communicate with the outside, forming... Figure 10 As shown, tools can then be inserted into the hidden groove 104 to disassemble the connecting bolt 163 and the connecting rod 164, thereby replacing the single water treatment unit 1.

[0059] To improve the installation stability of the frame 161, a fixing rod 165 and a fixing bracket 166 are also provided in the fixture 16. The fixing rod 165 is fixedly installed in the hidden groove 104. When the hidden groove 104 is opened on the side corresponding to the long side of the water treatment unit 1, the axis of the fixing rod 165 is parallel to the length direction of the water treatment unit 1; when the hidden groove 104 is opened on the side corresponding to the wide side of the water treatment unit 1, the axis of the fixing rod 165 is parallel to the width direction of the water treatment unit 1. Figure 8 As shown, the fixing bracket 166 is fixedly mounted on the frame 161, and the fixing bracket 166 is provided with a sliding groove 107, and the fixing rod 165 is slidably mounted in the sliding groove 107.

[0060] like Figure 11As shown, the connecting rod 164 has a first groove 108 and a second groove 109. The first groove 108 is located on the side of the connecting rod 164 near the frame 161, and the second groove 109 is located on the side of the connecting rod 164 away from the frame 161. The second groove 109 is connected to the first groove 108, and the inner diameter of the second groove 109 is larger than the inner diameter of the first groove 108. The first groove 108 extends to the bottom side of the connecting rod 164. When the connecting bolt 163 is tightened, the threaded head of the connecting bolt 163 engages with the second groove 109, thereby securing the connecting bolt 163 to the connecting rod 164. When the connecting bolt 163 is loosened, causing the threaded head of the connecting bolt 163 to disengage from the second groove 109, the threaded rod of the connecting bolt 163 can slide within the first groove 108, thereby enabling the rapid separation of the connecting rod 164 from the connecting bolt 163 and effectively improving the disassembly efficiency of the fixture 16.

[0061] like Figure 12 As shown, the cross-sections of the two first grooves 108 are both arc-shaped, and the distance between the two first grooves 108 is the radius of the arc corresponding to the first groove 108. The center of one first groove 108 is located at the center point of the other first groove 108. Therefore, when one of the connecting bolts 163 is loosened, the connecting rod 164 can be separated from the connecting bolt 163 by rotating the connecting rod 164, thereby realizing the quick disassembly of the two frames 161.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
