[0038] Next, in combination with the specific embodiments of the present utility model, the technical solutions in the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] As Figure 1-7 shown, a quickly installed curtain - type submerged ultra - filtration membrane module of the present utility model includes a frame 1, two water pipes 2, membrane filaments 3 and a connection mechanism 4.

[0040] Among them, the frame 1 is used to support other components and is used for the circulation of pure water. The frame 1 is usually set as a rectangular box - shaped structure.

[0041] The water pipe 2 is used to convey pure water.

[0042] The membrane filaments 3 are used to filter water. The membrane filaments 3 are in a fine tubular structure, and fine pores are provided on their surfaces. These fine pores play a role in filtering impurities, so that pure water can enter into the membrane filaments 3. The two water pipes 2 are connected through the membrane filaments 3, so that after the pure water enters into the membrane filaments 3, it can flow into the water pipe 2.

[0043] The connecting mechanism 4 is used to connect the water pipe 2 and the frame 1. A water conveyance channel 101 for circulating water is arranged in the frame 1. A communication hole 102 communicating with the water conveyance channel 101 is formed in the frame 1. The connecting mechanism 4 includes a stud 41 and a nut 42. One end of the water pipe 2 is fixedly provided with the stud 41. The stud 41 is coaxially arranged with the water pipe 2 and plugs its end. The nut 42 is connected to the stud 41 by thread fit and abuts against the frame 1. One end of the water pipe 2 away from the stud 41 abuts against the frame 1 in a sealed manner, and the inside of the water pipe 2 communicates with the communication hole 102, so that pure water can be discharged into the pure water storage device through the water conveyance channel 101; As Figure 2 shown, when the nut 42 rotates to the left, it can abut against the left side of the frame 1, so that the right end of the water pipe 2 abuts against the right side of the frame 1, thereby fixedly arranging the water pipe 2 on the frame 1 to realize the communication between the inside of the water pipe 2 and the water conveyance channel 101. During the installation process of the water pipe 2, the nut 42 and the stud 41 are always in a connected state, and there is no need to align the threads of the two again, making the installation operation of the water pipe 2 relatively convenient. At the same time, after the water pipe 2 is installed, its two ends abut and are fixed on the frame 1, and it will not shake during use, and can also ensure the normal operation of the ultrafiltration membrane module.

[0044] The connecting mechanism 4 further includes a sealing ring 43, an inner pipe 44 and an outer pipe 45. The sealing ring 43 abuts and is fixed between one end of the water pipe 2 away from the stud 41 and the frame 1 to improve the sealing performance between the water pipe 2 and the frame 1. The way that the end of the water pipe 2 abuts and seals the sealing ring 43 has not only a good sealing effect compared with the existing way of winding raw tape, but also is convenient for its maintenance.

[0045] As Figure 4 shown, the inner pipe 44 is hermetically fixed in the communication hole 102 and slidably arranged inside one end of the water pipe 2 away from the stud 41. The inner pipe 44 can play a role in positioning the inner side of the water pipe 2, avoiding the deflection of the water pipe 2 when subjected to external force, and ensuring the fixing firmness of the water pipe 2; Similarly, as Figure 5 shown, the outer pipe 45 is fixedly arranged on the frame 1 and slidably arranged outside one end of the water pipe 2 away from the stud 41. The sealing ring 43 is arranged between the inner pipe 44 and the outer pipe 45. Using the outer pipe 45 to position and protect the outside of the water pipe 2 can not only improve the fixing firmness of the water pipe 2, but also protect the sealing ring 43 from being damaged.

[0046] As Figure 4As shown, the sealing ring 43 includes a sealing ring 431 and a limiting ring 432. Among them, the sealing ring 431 is abutted and fixed between the end of the water pipe 2 away from the stud 41 and the frame 1, and is located between the inner pipe 44 and the outer pipe 45. An annular groove 201 is provided at the end of the water pipe 2 away from the stud 41. The limiting ring 432 is integrally formed on one side of the sealing ring 431 and is clamped with the annular groove 201. The cross-section of the sealing ring 43 formed by the combination of the sealing ring 431 and the limiting ring 432 is T-shaped, which not only increases the contact area between the sealing ring 43 and the water pipe 2, but also improves the fixing firmness of the two, achieving a good sealing effect.

[0047] As Figure 2 and Figure 3 shown, an assembly hole 103 is provided on the frame 1. The stud 41 is slidably arranged in the assembly hole 103. When the water pipe 2 is fixed in the frame 1, the stud 41 extends into the assembly hole 103, so as to support one end of the water pipe 2, playing a certain pre-fixing role in the installation process of the water pipe 2. Especially when the other end of the water pipe 2 is inserted into the inner pipe 44, there is no need to support the water pipe 2 during the installation process of the water pipe 2. Just rotate the nut 42 and prevent the water pipe 2 from rotating.

[0048] As Figure 3 shown, the nut 42 is rhombus-shaped. Compared with ordinary hexagonal or circular nuts 42, it is flat and long, which can facilitate the rotation of the nut 42 and basically does not require tools to rotate it. Preferably, the length of one diagonal of the nut 42 is greater than the outer diameter of the water pipe 2, and the length of the other diagonal is less than the outer diameter of the water pipe 2. As Figure 3 shown in the state, the height of the nut 42 is greater than the outer diameter of the water pipe 2, so as to extend outside the frame 1 for rotating the nut 42. After it rotates 90 degrees, its height is less than the outer diameter of the water pipe 2 at this time, so that it can be hidden in the frame 1 to avoid interference and collision between the nut 42 and other components during the use of the device.

[0049] As Figure 7 shown, the frame 1 includes a frame body 11 and a joint 12. Among them, the water conveyance channel 101 and the communication hole 102 are both arranged on the frame body 11. The nut 42 and the water pipe 2 are both abutted against the frame body 11, so that the frame body 11 not only has the function of conveying water, but also has the function of supporting other components. The joint 12 is fixedly arranged on the frame body 11 and is communicated with the water conveyance channel 101. The outside of the joint 12 is provided with threads to be connected with the water conveyance pipeline to convey the pure water body to the designated position.

[0050] As Figure 1As shown, it is preferred that the frame body 11 be welded by a plurality of tubular structures, such as rectangular tubes, which are hollow structures. They not only have a good supporting effect but also do not need to additionally open a water delivery channel 101. Only the adjacent two tubular structures need to be opened up and the two ends of the tubular structure need to be blocked.

[0051] The usage method of a quickly installed curtain-type submerged ultrafiltration membrane module of the present utility model is as follows:

[0052] When installing the water delivery pipe 2, first insert the stud 41 at the end of the water delivery pipe 2 into the assembly hole 103, then slide the water delivery pipe 2 along its axial direction so that the end of the water delivery pipe 2 away from the stud 41 is inserted between the inner pipe 44 and the outer pipe 45, and finally rotate the nut 42 to make the water delivery pipe 2 abut and seal with the sealing ring 43. Of course, after the stud 41 is inserted into the assembly hole 103, the nut 42 can be directly rotated. By the abutment of the nut 42 against the frame 1 and its threaded fit with the stud 41, the water delivery pipe 2 is pushed to move along its axial direction. Finally, the end of the water delivery pipe 2 away from the stud 41 is inserted between the inner pipe 44 and the outer pipe 45 and abuts the sealing ring 43, so that the pure water in the frame 1, the water delivery pipe 2 and the membrane filaments 3 is conveyed to the designated position through the joint 12.

[0053] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
