Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a rapid assembly wastewater purification device. Background Technology

[0002] Ultrafiltration membrane water purification technology is a pressure-driven membrane separation technology mainly used in the field of water treatment. It purifies water quality through the screening effect of membrane pore size. The pore size of ultrafiltration membranes is typically between 1 and 100 nanometers, which can effectively retain large molecules, colloids, particles, and bacteria, while allowing small molecule solutes and water molecules to pass through, thereby achieving the purpose of purification.

[0003] When purifying water, submerged ultrafiltration equipment is often used to purify and filter the water. Submerged ultrafiltration is a new technology that uses membrane modules to replace the secondary sedimentation tank in the traditional process for solid-liquid phase separation.

[0004] The patent document with publication number CN222434228U discloses an integrated pressure-type submerged ultrafiltration membrane water purification device, in which the ultrafiltration membrane module is set inside the tank and the bottom of the tank is provided with support legs. This type of submerged water treatment device is usually set on a bracket or skid platform. During installation, it needs to be assembled by bolts or welding. The whole process is relatively cumbersome and not easy to transport. Especially for some water treatment projects that are adapted to local conditions, the ease and speed of assembly of the entire water treatment equipment is particularly important.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0019] like Figure 1-6 As shown, a quick-assembly wastewater treatment device includes: a tank 1 for containing wastewater to be treated; an ultrafiltration membrane assembly 2 installed inside the tank 1; and a support 3 located at the bottom of the tank 1 and engaging with the tank 1.

[0020] This rapid assembly wastewater purification device consists of three main parts: a tank 1, an ultrafiltration membrane module 2, and a support frame 3.

[0021] Tank 1 serves as the main container of the device, and its internal space is designed specifically to accommodate the wastewater to be treated, providing the necessary space for the subsequent ultrafiltration membrane filtration process.

[0022] The ultrafiltration membrane module 2 is installed inside the tank 1 using a frame-mounted method. Whether for disassembly, assembly, or maintenance, the ultrafiltration membrane module 2 can be directly hoisted without disassembling and fixing the tank 1 and the ultrafiltration membrane module 2, which is very convenient.

[0023] The bracket 3 is located at the bottom of the tank 1 and fits tightly with the tank 1 via a snap-fit ​​connection. Compared with traditional bolt or welding methods, this snap-fit ​​design significantly simplifies the installation process, greatly shortens the assembly time, and improves work efficiency. More importantly, it facilitates the disassembly and transportation of the equipment, enabling the device to flexibly adapt to water treatment needs in different scenarios.

[0024] In some further embodiments, the ultrafiltration membrane assembly 2 includes a membrane frame 23 and a filter module 24, wherein there are multiple filter modules 24 connected to the membrane frame 23.

[0025] The ultrafiltration membrane module 2 consists of a membrane frame 23 and multiple filter modules 24. The arrangement of multiple filter modules 24 significantly increases the filtration area, thereby improving wastewater treatment efficiency. These filter modules 24 work together to enhance the retention capacity of impurities in the wastewater, ensuring excellent purification results. Simultaneously, the membrane frame 23 provides stable support for the filter modules 24, ensuring their stability within the tank 1. This allows the ultrafiltration membrane module 2 to maintain excellent working condition during long-term operation, effectively extending its service life.

[0026] In some further embodiments, the membrane holder 23 is provided with a sliding rod 21, and the outer peripheral wall of the tank 1 is provided with a sliding groove 10; when the ultrafiltration membrane assembly 2 is located inside the tank 1, the sliding rod 21 is located in the sliding groove 10.

[0027] The membrane holder 23 is equipped with a sliding rod 21, while the outer peripheral wall of the tank 1 has a matching sliding groove 10. During the installation of the ultrafiltration membrane module 2, the sliding rod 21 can smoothly slide into the sliding groove 10, providing precise guidance and ensuring that the ultrafiltration membrane module 2 can be accurately positioned inside the tank 1. This design not only simplifies the installation process but also avoids problems such as reduced filtration efficiency or equipment damage that may be caused by installation position deviations.

[0028] During assembly, the sliding rod 21 can be matched and aligned with the sliding groove 10, and then the membrane frame 23 can be gradually lowered to achieve the installation of both. Due to the setting of the sliding rod 21 and the sliding groove 10, the ultrafiltration membrane module 2 located inside the tank 1 will not move due to water flow fluctuations, ensuring stability during operation.

[0029] In some further embodiments, the side wall of the sliding rod 21 is provided with a plurality of vertically arranged snap-fit ​​grooves 22, and the side wall of the sliding groove 10 is provided with snap-fit ​​rods 40 corresponding to the snap-fit ​​grooves 22. One end of the snap-fit ​​rod 40 facing the inside of the sliding groove 10 is provided with a snap-fit ​​connector 41 for snap-fitting with the snap-fit ​​groove 22, and the other end of the snap-fit ​​rod 40 is screwed with a limiting nut 43. A first spring 42 is provided between the snap-fit ​​connector 41 and the side wall of the sliding groove 10, and the first spring 42 is sleeved on the snap-fit ​​rod 40.

[0030] As the sliding rod 21 descends in the sliding groove 10, the snap-fit ​​connector 41 continuously engages with and disengages from the snap-fit ​​groove 22 until the membrane frame 23 is completely supported by the upper edge of the tank body 1.

[0031] The upper sidewall of the snap-fit ​​groove 22 is inclined, and the upper sidewall of the snap-fit ​​connector 41 is inclined in the same direction. This allows the sliding rod 21 to move only downwards during descent and not upwards, thus realizing the function of the ratchet mechanism.

[0032] When the limit nut 43 is tightened, the locking rod 40 will move away from the locking groove 22 under the action of the limit nut 43. When the locking connector 41 is completely disengaged from the locking groove 22, the sliding rod 21 can move upward, that is, the ultrafiltration membrane module 2 is lifted out of the tank 1.

[0033] In order to accommodate the locking connector 41, a clearance groove 100 is specially provided on the side wall of the sliding groove 10 corresponding to the locking connector 41, and the first spring 42 is located in the clearance groove 100.

[0034] In some further embodiments, the support 3 includes a support ring 30 and a support leg 31, with the support leg 31 connected below the support ring 30; an annular support groove 5 is provided above the support ring 30, the annular support groove 5 including an annular bearing plate 50 at the bottom and a limiting ring 51 on the side; the bottom wall of the tank 1 abuts against the annular bearing plate 50, and the side wall of the tank 1 is limited and engaged with the limiting ring 51 on the side.

[0035] This design allows the tank 1 to be stably placed on the support 3. The annular support plate 50 provides reliable support for the tank 1, preventing it from sinking or tilting. The side limiting ring 51 limits the movement of the tank 1, preventing it from swaying in the horizontal direction and ensuring the stability of the entire device during operation. Meanwhile, the annular support groove 5 has a simple structure and is easy to manufacture, effectively reducing the manufacturing cost of the support 3.

[0036] In some further embodiments, a locking rod is hinged inside the annular support groove 5. The locking rod includes a trigger rod 60 and a locking rod 61 located at the bottom. The angle between the trigger rod 60 and the locking rod 61 is less than 90°. The locking rod is configured to drive the locking rod 61 to lock the tank 1 when the trigger rod 60 is pressed down on the tank 1.

[0037] During actual installation, when tank 1 is placed on the annular support groove 5, the weight of tank 1 presses down on trigger rod 60, causing locking rod to rotate. This, in turn, drives locking rod 61 to move towards tank 1, ultimately locking tank 1. This locking method utilizes the weight of tank 1 itself, requiring no additional operation and achieving automatic locking, thus improving installation convenience. Simultaneously, the locking rod's structural design is reasonable, ensuring reliable locking and preventing tank 1 from loosening due to vibration or other reasons during operation.

[0038] The connection between the trigger rod 60 and the locking rod 61 in the locking rod is hinged to the annular support groove 5, and the movement of the locking rod is essentially a lever movement.

[0039] Additionally, a receiving groove is provided at the bottom of the tank 1 to accommodate the trigger rod 60. The actual point where the trigger rod 60 is pressed down is the top wall of the receiving cavity 13.

[0040] The arrangement of the receiving cavity 13 also allows the entire tank 1 to be better supported by the annular support plate 50.

[0041] The top of the locking rod 61 is provided with an arc-shaped rubber plate 610 to increase the fit to the outer wall of the tank 1.

[0042] In addition, a second spring 611 is provided between the locking rod 61 and the limiting ring 51. The second spring 611 is used to make the locking rod 61 tilt towards the limiting ring 51 when the trigger rod 60 is not under pressure, so as to avoid interference between the tank 1 and the top of the locking rod 61 when it falls.

[0043] In some further embodiments, the bottom of the tank 1 is provided with an air inlet 12, and the inside of the tank 1 is provided with an aeration pipe frame 11, with the air inlet 12 connected to the aeration pipe frame 11.

[0044] The aeration system introduces gas into the aeration tube frame 11 through the air inlet 12. The gas is then evenly distributed into the wastewater inside the tank 1 through the aeration tube frame 11, generating a large number of microbubbles. As these microbubbles rise, they collide and rub against impurities in the wastewater, suspending the impurities in the wastewater. This prevents impurities from depositing on the surface of the ultrafiltration membrane, avoiding clogging of the ultrafiltration membrane and improving its service life and filtration efficiency.

[0045] In some further embodiments, the tank 1 has a drain outlet 14 at the bottom; the tank 1 has a water inlet 15 at the bottom and the ultrafiltration membrane assembly 2 has a water outlet 20 at the top.

[0046] The bottom of tank 1 is equipped with a drain port 14, which is used to discharge impurities and sediments trapped after ultrafiltration membrane filtration. By periodically opening the drain port 14, the dirt at the bottom of tank 1 can be discharged, keeping the inside of tank 1 clean and ensuring the normal operation of the device.

[0047] A water inlet 15 is provided at the bottom of the tank body 1 for introducing the wastewater to be treated into the tank body 1. A water outlet 20 is provided at the top of the ultrafiltration membrane module 2, and the purified water after being filtered by the ultrafiltration membrane is discharged from the water outlet 20, thus realizing the purification treatment of wastewater.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
