Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment filter membrane testing, and in particular relates to a sewage treatment filter membrane corrosion resistance testing device. Background Art

[0002] MBR, or membrane bioreactor, is an innovative sewage treatment device that cleverly combines ultrafiltration and microfiltration membrane separation technology with bioreactors in sewage treatment, thereby giving full play to the advantages of both. In this reactor, ultrafiltration and microfiltration membrane components play an important role in mud-water separation, completely replacing traditional secondary sedimentation tanks. Through the application of membrane components, the bioreactor can maintain a high concentration of activated sludge, thereby increasing the organic load of biological treatment, which not only reduces the footprint of sewage treatment facilities, but also effectively reduces the generation of residual sludge.

[0003] The strong polar solvents present in industrial wastewater can dissolve membrane materials such as PVDF, causing irreversible damage to the membrane filaments. During long-term use, the membrane filaments may be contaminated by inorganic salt scaling, oil, organic matter, colloids and other substances in the water, resulting in degradation of membrane performance or even damage. Most of the existing MBR membrane corrosion resistance tests are carried out by introducing compressed air of a certain pressure into the water production flange of the membrane component. The operator is required to observe whether there are bubbles in the water. If the membrane filaments are damaged, bubbles will emerge from the damaged area. The operator then marks the damaged area of the membrane with a label and repairs it later. These steps all require staff to operate in water, which is not only inconvenient but also prone to errors and has a low level of automation. Therefore, it is necessary to propose a sewage treatment filter membrane corrosion resistance detection equipment. Summary of the Invention

[0008] Preferably, the mobile control component includes a screw slide, a screw guide rail, a middle guide platform, a positioning auxiliary plate, a screw lever and a screw control console. The screw control console is arranged on the equipment base, the screw lever is arranged between the screw control consoles, the middle guide platform is fixed to the equipment base, the screw guide rail is arranged between the middle guide platforms, the screw slide is slidably arranged on the screw lever, the positioning auxiliary plate is slidably arranged on the screw guide rail, and a movable connecting plate is provided between the screw slide and the positioning auxiliary plate.

[0009] Wherein, the trigger button and the LED light are electrically connected.

[0010] Preferably, two groups of water-collecting membrane boxes are provided, wherein one group of water-collecting membrane boxes is provided at the bottom of the lead screw slide and the positioning auxiliary plate, and the other group of water-collecting membrane boxes is provided on the inner wall of the water storage tank.

This method brings the following advantages:

[0018] (1) In order to solve the problem that the existing sewage treatment filter membrane corrosion resistance detection scheme is difficult to quickly mark the damaged part of the membrane, the present invention proposes a positioning auxiliary component and a surrounding test component. According to the hydrophobicity of the super-hydrophobic hairs, when bubbles impact the super-hydrophobic hairs, the protective film formed around the hydrophobic hairs is destroyed, and the hydrophobic hairs are detached from the positioning holes. As a result, the central connecting column loses its support for the magnetic shielding plate. The magnetic shielding plate cannot prevent the adsorption magnetic plate and the sliding magnetic block from adsorbing each other. The magnetic adsorption effect between the sliding magnetic block and the adsorption magnetic plate causes the trigger button to be pressed by the sliding magnetic block. Then, the LED lights corresponding to the group of trigger buttons light up, indicating that there is a damaged part at the corresponding position on the membrane bundle. The operator only needs to observe the lighting or extinguishing status of the several groups of LED lights arranged around the several groups of external fixing rings in the several groups of positioning auxiliary components and the surrounding test components to understand the specific situation of the damage on the membrane bundle, providing an automated experience.

[0019] (2) By controlling the rotation of the lead screw lever through the lead screw console, the movement of the lead screw slide can be controlled, and the positioning auxiliary plate can be driven to move by moving the connecting plate, thereby driving one end of the membrane bundle to move through the water collecting membrane box, and the membrane bundle can be straightened to prevent the membrane bundle from being entangled and affecting the detection process.

[0035] like Figure 3 and Figure 5-Figure 7 As shown, the positioning auxiliary component 1 includes an arc-shaped clamping plate 19, a silicone pad 20, a guide rail 21, an external fixed ring 22 and a sliding magnetic block 23. The arc-shaped clamping plate 19 is arranged on the outer wall of the membrane bundle 7, one end of the silicone pad 20 is arranged on the arc-shaped clamping plate 19, and the other end of the silicone pad 20 is arranged on the surrounding ring 8.

[0036] like Figure 1-Figure 2 As shown, the mobile control component 3 includes a screw slide 24, a screw guide rail 25, a middle guide platform 26, a positioning auxiliary plate 27, a screw lever 28 and a screw control console 29. The screw control console 29 is arranged on the equipment base 4, the screw lever 28 is arranged between the screw control consoles 29, the middle guide platform 26 is fixed to the equipment base 4, the screw guide rail 25 is arranged between the middle guide platform 26, the screw slide 24 is slidably arranged on the screw lever 28, the positioning auxiliary plate 27 is slidably arranged on the screw guide rail 25, and a movable connecting plate is provided between the screw slide 24 and the positioning auxiliary plate 27.

[0037] like Figure 4 and Figure 9 As shown, the trigger button 16 and the LED light 9 are electrically connected.

[0038] like Figure 1-Figure 2 As shown, there are two groups of water collecting membrane boxes 6 , one group of water collecting membrane boxes 6 is arranged at the bottom of the screw slide 24 and the positioning auxiliary plate 27 , and the other group of water collecting membrane boxes 6 is arranged on the inner wall of the water storage tank 5 .

[0039] like Figure 9 As shown, the trigger operation slot 10 is connected to the impact through slot 11, the trigger button 16 is a waterproof button, the trigger operation slot 10 is connected to the drop through slot 12, the magnetic shielding plate 15 is not fixed to the trigger operation slot 10, the magnetic shielding plate 15 is located directly above the drop through slot 12, and the central connecting column 14 and the super-hydrophobic hairs 13 are located on the side close to the trigger button 16.

[0040] like Figure 5 As shown, the LED lamp 9 is arranged on the outer fixing ring 22.

[0041] When in use, first pass the arc-shaped clamping plates 19 in the several groups of positioning auxiliary components 1 and the surrounding test components 2 through the membrane bundle 7, so that the arc-shaped clamping plates 19 can be located on the outside of the membrane bundle 7 through the silicone pad 20 without exerting pressure on the membrane bundle 7. Add water to the water storage tank 5, and introduce compressed air into the membrane bundle 7 through the water collecting membrane box 6. Bubbles will be ejected from the damaged part of the membrane bundle 7. The bubbles will enter a group of impact grooves 11 at the corresponding position through the position where they are ejected, and enter through the gap between the adsorption magnetic plate 17 and the trigger operation groove 10. When the air bubble enters the trigger operation groove 10, the air bubble impacts the super-hydrophobic hairs 13. Due to the hydrophobicity of the super-hydrophobic hairs 13, when the water surface in the water storage tank 5 is previously entered, several groups of evenly distributed hydrophobic hairs form a protective film in the surrounding water area. At this time, several groups of hydrophobic hairs will not separate from the positioning holes 18, and several groups of hydrophobic hairs will not fall off. When the air bubble impacts the super-hydrophobic hairs 13, the protective film formed around the hydrophobic hairs is destroyed, and the hydrophobic hairs separate from the positioning holes 18, so that the central connecting column 14 loses its connection. The support function of the magnetic shielding plate 15 is removed, and the magnetic shielding plate 15 falls from the drop groove 12, and cannot prevent the adsorption magnetic plate 17 and the sliding magnetic block 23 from adsorbing each other, so the sliding magnetic block 23 gradually slides along the guide rail 21 toward the adsorption magnetic plate 17, and enters the trigger operation groove 10 to adhere to the adsorption magnetic plate 17. At this time, the trigger button 16 is also pressed by the sliding magnetic block 23, so the LED light 9 corresponding to the group of trigger buttons 16 lights up, indicating that the corresponding position on the membrane bundle 7 has a damaged part, and the operator only needs to observe several groups of positioning auxiliary The lighting or extinguishing status of several groups of LED lights 9 arranged around several groups of external fixing rings 22 in the auxiliary component 1 and the surrounding test component 2 can mark the damage condition on the membrane filament bundle 7, providing an automated experience; by controlling the rotation of the screw lever 28 through the screw control console 29, the movement of the screw slide 24 can be controlled, and the positioning auxiliary plate 27 can be driven to move by the moving connecting plate, so that one end of the membrane filament bundle 7 is driven to move through the water collecting membrane box 6, which can straighten the membrane filament bundle 7 to prevent the membrane filament bundle 7 from being entangled and affecting the progress of the detection process.
