[0033] Example 2

[0035] Specifically, the outer ring of the aeration plate 102 is fixedly connected with the second fixing ring 102a, and the size of the second fixing ring 102a is adapted to the first fixing ring 101d. Through the action of the aeration plate 102, air can be input into the placement tube 101 to achieve stirring in the placement tube 101, and the material in the placement tube 101 is stirred by the aeration plate 102, which will not affect the detection of membrane filaments, and by increasing the activity of sludge, the detection can be made more thorough.

[0036] Specifically, the fixing assembly 103 includes a first arc plate 103a, a second arc plate 103b and a limit piece 103c arranged at one end of the first arc plate 103a, one end of the first arc plate 103a is fixedly connected to a first sleeve 103d, one end of the second arc plate 103b is fixedly connected to a second sleeve 103g, the second sleeve 103g is rotatably matched with the first sleeve 103d through a limit rod 103h, and the inner circles of the first arc plate 103a and the second arc plate 103b are adapted to the first fixing ring 101d and the second fixing ring 102a.

[0037] Furthermore, the limiting member 103c includes two first fixed plates 103c-1 symmetrically fixed to the outer circle of one end of the first arc-shaped plate 103a, a fixed shaft 103c-2 fixed between the two first fixed plates 103c-1, a movable seat 103c-3 rotating on the outer circle of the fixed shaft 103c-2, and a threaded rod 103c-4 rotating on one end of the movable seat 103c-3, the outer circle of the threaded rod 103c-4 is provided with a threaded tube 103c-5, the threaded tube 103c-5 is threadedly matched with the threaded rod 103c-4, and one end of the threaded tube 103c-5 is fixedly connected to a knob 103c-6.

[0038] Furthermore, the outer circle of one end of the second arc-shaped plate 103b is symmetrically fixedly connected to two second fixing plates 103e, and the opposite sides of the two second fixing plates 103e are fixedly connected to blocks 103f, and the threaded tube 103c-5 is adapted to the two blocks 103f.

[0039] The first curved plate 103a and the second curved plate 103b can fix the first fixing ring 101d and the second fixing ring 102a.

The first sleeve 103d, the limiting rod 103h and the second sleeve 103g can ensure the rotation of the first curved plate 103a and the second curved plate 103b. The limiting member 103c can ensure the stability of the connection between the first curved plate 103a and the second curved plate 103b, that is, the stability of the connection between the first curved plate 103a and the second curved plate 103b to the aeration plate 102 and the placement tube 101 is ensured.

[0040] Furthermore, Figure 7 As shown, this is another placement diagram of the placement tube 101 and the aeration plate 102. At this time, one end of the placement tube 101 is closed, and a placement opening is opened on the side wall of the placement tube 101. The aeration plate 102 is placed on the side wall of the placement tube 101 through the placement opening, and this fixing method is to adhere with epoxy resin. This placement method can also meet the detection of membrane filaments, and can perform aeration from different angles to observe the detection effect of the membrane filaments.

[0041] When the device is used and needs to be installed, firstly, the aeration plate 102 is placed into the placing tube 101 from the side of the placing tube 101 close to the first fixing ring 101d, so that one side of the first fixing ring 101d contacts one side of the second fixing ring 102a, and a sealing gasket is placed at the connection between the first fixing ring 101d and the second fixing ring 102a to ensure the sealing of the device, and then the inner rings of the first curved plate 103a and the second curved plate 103b are sleeved on the first fixing ring 101d and the second fixing ring. The outer ring of 102a is then pulled by the threaded barrel 103c-5, and the threaded rod 103c-4 is rotated around the fixed axis 103c-2 to between the two blocks 103f, and then the knob 103c-6 is turned. At this time, the threaded barrel 103c-5 will rotate with the threaded rod 103c-4, driving the threaded barrel 103c-5 to move and contact with the block 103f, and then the first arc plate 103a and the second arc plate 103b can be tightened to fix the aeration plate 102 tightly to one end of the placement tube 101.

[0042] Example 3

[0043] Reference Figure 3 to Figure 7, which is the third embodiment of the utility model, and is based on the previous two embodiments. This embodiment provides a hollow fiber membrane filament detection device, which includes a bearing unit 200, and the bearing unit 200 includes a fourth connecting cylinder 203 arranged on one side of the aeration unit 100, a bearing assembly 205 movably arranged in the inner ring of the fourth connecting cylinder 203, and a third connecting cylinder 202 fixedly installed on one side of the fourth connecting cylinder 203 through an adjusting cylinder 204, a guide assembly 201 is fixedly installed on one side of the third connecting cylinder 202, and the inner ring of the fourth connecting cylinder 203 is threadedly matched with the outer ring of the first connecting cylinder 101a.

[0044] The membrane filaments selected for inspection can be fixed by the supporting assembly 205, and the membrane filaments can be fixed inside the placement tube 101 through the cooperation among the third connecting tube 202, the fourth connecting tube 203 and the adjusting tube 204, so that the membrane filaments can be inspected through the cooperation between the placement tube 101 and the aeration plate 102. When the inspection is carried out, liquid will seep out from the hollow part of the membrane filaments, and because the device is placed vertically, the guide assembly 201 plays a role of diversion.

[0045] Specifically, the flow guide assembly 201 includes a second connecting tube 201a, a connecting plate 201b fixed to one end of the second connecting tube 201a, and a liquid outlet 201c movably mounted on one side of the connecting plate 201b. The liquid outlet 201c is connected to the second connecting tube 201a through the connecting plate 201b.

[0046] Furthermore, the liquid outlet 201c is movably installed. If the membrane filaments are covered with sludge, the liquid outlet 201c can be disassembled and connected to the external water pump output pipe during inspection. The membrane filaments can then be backwashed by the action of the water pump, or increasing the aeration volume of the aeration plate 102 can also have a backwashing effect on the membrane filaments to prevent clogging of the membrane filaments. Through the arrangement of the connecting plate 201b and the second connecting tube 201a, the water pump delivers water through the liquid outlet 201c and backwashes the membrane filaments through the connecting plate 201b and the second connecting tube 201a. The arrangement of the connecting plate 201b and the second connecting tube 201a can reduce the impact force of the water flow on the membrane filaments, thereby preventing the membrane filaments from easily falling off the supporting assembly 205.

[0047] Specifically, the outer ring of one end of the third connecting tube 202 is threadedly matched with the inner ring of the other end of the second connecting tube 201a, the other end of the third connecting tube 202 is fixedly connected with the third fixing ring 202a, and the adjusting tube 204 is movably sleeved on the outer ring of the third connecting tube 202; one end of the fourth connecting tube 203 is fixedly connected with the fifth connecting tube 203a, and the outer ring of the fifth connecting tube 203a is threadedly matched with the inner ring of the adjusting tube 204.

[0048] Through the action of the third connecting tube 202 and the adjusting tube 204, the silicone plug 205a can be fixed at the connection between the third connecting tube 202 and the fourth connecting tube 203 through the extension ring 205b, thereby ensuring the stability of the silicone plug 205a. In addition, the setting of the adjusting tube 204, the third connecting tube 202 and the fourth connecting tube 203 also facilitates the installation and disassembly of the supporting assembly 205.

[0049] Specifically, the bearing assembly 205 includes a silicone plug 205a, an extension ring 205b fixed to the outer ring of the silicone plug 205a, and four mounting holes 205c opened at one end of the silicone plug 205a. The extension ring 205b is located at the connection between the fifth connecting tube 203a and the third fixing ring 202a.

[0050] Through the extension ring 205b, since the silicone plug 205a is made of silicone, the extension ring 205b is placed between the third connecting tube 202 and the fourth connecting tube 203, and the connection between the two can be sealed. At the same time, since the silicone plug 205a itself has a large friction force, after the membrane wire is placed in the installation hole 205c, due to the friction generated between the two, it can also ensure that the membrane wire remains stable during testing or cleaning, and the installation holes 205c are set to four to ensure the redundancy of testing the membrane wire.

[0051] When in use, first pass the membrane thread to be detected through the mounting hole 205c. The friction between the membrane thread and the mounting hole 205c will ensure the stability of the membrane thread. After the placement is completed, the fourth connecting tube 203 is put on the silicone plug 205a from the end away from the inclined surface of the silicone plug 205a, and the extension ring 205b will fit with one end of the fifth connecting tube 203a. Then, the outer ring is sleeved with the third connecting tube 202 with an adjusting tube 204 and placed on the other side of the silicone plug 205a. Then, the adjusting tube 204 is connected to the thread on the fifth connecting tube 203a to fix it. Then, the second connecting tube 201a is threadedly connected to the third connecting tube 202. Finally, the fourth connecting tube 203 is threadedly connected to the first connecting tube 101a. Then, the membrane thread can be detected.

[0052] In summary, when in use, first fix the aeration plate 102 to the placement tube 101 through the fixing assembly 103, then fix the membrane filaments in the mounting hole 205c, and then fix the silicone plug 205a through the third connecting tube 202, the fourth connecting tube 203 and the adjusting tube 204, and threadedly connect it to the first connecting tube 101a through the fourth connecting tube 203, and then connect the water inlet 101c to the water inlet pipe, and the water outlet 101b to the water outlet pipe, so that the membrane filaments can be detected. The device is a sludge deposition process under aeration conditions. If the membrane is very hydrophilic or other additives are added to the membrane surface, the membrane filaments will not hang mud under long-term operation, and the flux is stable. If the membrane filaments are covered with sludge, the membrane filaments can be cleaned by increasing the aeration volume or backwashing, see Example 2.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
