Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a multilayer ultrafiltration membrane water treatment device. Background Technology

[0002] Multilayer ultrafiltration membrane water treatment equipment is a type of water treatment device that uses ultrafiltration membrane technology as its core. Through its multilayer membrane structure, it achieves efficient retention of suspended solids, colloids, bacteria, viruses, and other impurities in water, thereby purifying the water. This device has advantages such as small footprint, high-quality effluent, high degree of automation, and stable operation, and is widely used in drinking water treatment, industrial wastewater reuse, and seawater desalination pretreatment.

[0003] Some existing devices require the removal, cleaning, or replacement of the mold after long-term use. However, most existing molds are removed manually by workers. This method results in uneven force distribution when moving the mold, which causes the mold to tilt and rub against the surface of the membrane shell. This is not only inconvenient when removing the mold, but also affects the cleaning efficiency of the device.

[0004] Meanwhile, some existing devices require manual application of lubricating oil to the inner wall of the membrane shell when removing the mold body to reduce the coefficient of friction and facilitate the movement of the mold body. However, when manually applying lubricating oil, the gap between the mold body and the membrane shell is small, which not only makes the application inconvenient but also affects the efficiency of removing the mold body, thus affecting the applicability of the device.

[0009] Preferably, the extrusion mechanism includes a storage tank communicating with the inner cavity of the fixed groove and a sealing head threadedly connected to the upper part of the inner cavity, wherein a one-way valve is installed in the inner cavity of the sealing head.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-4 As shown, a multilayer ultrafiltration membrane water treatment device includes a mounting frame 1. A piping mechanism 2 is installed inside the mounting frame 1, and membrane housings 3 are mounted on the surface of the piping mechanism 2. The piping mechanism 2 connects the various membrane housings 3, facilitating water filtration. The mounting frame 1 provides support for the piping mechanism 2 and the membrane housings 3. A fixing groove 4 is provided inside the membrane housing 3, and a nozzle 5 is connected to the inner cavity of the fixing groove 4. Several nozzles 5 are arranged in a circular array around the center of the membrane housing 3. A squeezing mechanism 6 is provided inside the fixing groove 4, which stores lubricating oil. When the device needs to be disassembled, the operator can use the squeezing mechanism 6 to discharge the lubricating oil through the fixing groove 4 from the nozzles 5 to the inner wall of the membrane housing 3, making it easier to remove and place the membrane housing. This effectively reduces the difficulty of replacing the membrane housing and improves the maintenance efficiency of the device. A connecting block 8 is fixedly connected to the bottom of the membrane housing 3, and a connecting element is slidably connected to the surface of the connecting block 8. The inner cavity of the shell 7 and the surface of the connecting block 8 are both designed with a T-shape. The shell 7 and the connecting block 8 work together to prevent the shell 7 from easily detaching from the surface of the connecting block 8, effectively improving the stability of the shell 7 during use and preventing instability from affecting subsequent use. An adjustment mechanism 9 is installed at one end of the shell 7. With the cooperation of the adjustment mechanism 9, the mold body can be limited, so that the mold body can move parallel when the mold body is picked up, making it easier and faster to remove the mold body. A fixing tube 10 is fixedly connected to the surface of the shell 7, and a ball bearing 11 is fixedly connected to the inner cavity of the fixing tube 10. The surface of the ball bearing 11 is movably connected to the surface of the shell 3. With the cooperation of the fixing tube 10 and the ball bearing 11, the movement of the shell 7 is more stable, reducing the possibility of instability affecting the removal of the mold body and effectively improving the applicability of the device.

[0023] The extrusion mechanism 6 includes a storage tank 61 connected to the inner cavity of the fixed groove 4. A sealing head 62 is threadedly connected to the upper part of the inner cavity of the storage tank 61. A one-way valve 63 is installed in the inner cavity of the sealing head 62. The surface of the storage tank 61 has a flexible structure design. The one-way valve 63 works in conjunction with the storage tank 61. Under this action, when it is necessary to add lubricating oil to the inside of the membrane shell 3, the operator can directly squeeze the storage tank 61. With the cooperation of the one-way valve 63, the lubricating oil inside the storage tank 61 will be squeezed into the inside of the fixed groove 4. With the cooperation of the nozzle 5, the lubricating oil is discharged. With the cooperation of the material of the storage tank 61 itself and the one-way valve 63, the storage tank 61 can recover after deformation, which facilitates the subsequent use of the storage tank 61. The surface of the storage tank 61 is provided with scale lines 12. The scale lines 12 work in conjunction with the storage tank 61. Under this action, the operator can easily observe the lubricating oil inside the storage tank 61 through the scale lines 12, which facilitates the addition of lubricating oil to the storage tank 61.

[0024] The adjustment mechanism 9 includes a connecting seat 91 fixed to the surface of the connecting shell 7. A movable frame 92 is rotatably connected to the surface of the connecting seat 91. One side of the movable frame 92 can conveniently limit the mold body, thereby establishing a connection with the mold body. A positioning hole 93 is opened on the surface of the movable frame 92. A positioning pin 94 is slidably connected to the surface of the connecting seat 91. The surface of the positioning pin 94 is slidably connected to the inner cavity of the positioning hole 93. Under this action, the connecting seat 91 will not easily rotate by rotating the movable frame 92 and then embedding the positioning pin 94 into the interior of the positioning hole 93, thereby facilitating the subsequent movement of the mold body. When the movable frame 92 is not needed, the movable frame 92 can be directly rotated to the bottom to avoid affecting the connection between the pipeline mechanism 2 and the membrane shell 3.

[0025] It is worth noting that the technical features such as the mounting bracket 1, pipeline mechanism 2, and membrane housing 3 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0026] Working principle: First, when it is necessary to remove the mold inside the membrane shell 3, the operator disconnects the membrane shell 3 from the pipeline mechanism 2, then rotates the movable frame 92 to connect it with the mold, and then inserts the positioning pin 94 into the positioning hole 93 to limit the movable frame 92. Then, the movable frame 92 is pulled, which reduces the tendency of the mold to tilt during movement, so that the mold can be removed horizontally, which is effective and convenient for removing the mold. When the friction is large during removal, the storage tank 61 can be pressed. With the cooperation of the one-way valve 63, the lubricating oil inside the storage tank 61 will be squeezed into the fixed groove 4 and discharged from the nozzle 5, thereby reducing the friction when the mold moves, making the device more convenient for replacing the mold and effectively improving the applicability of the device.
