Description

Technical Field

[0001] The present invention relates to the technical field of MBR sewage treatment, and specifically relates to an integrated MBR sewage treatment device and a treatment process. Background Art

[0002] MBR sewage treatment is a commonly used method in modern sewage treatment. The membrane bioreactor technology it adopts is a new technology that combines biological treatment technology and membrane separation technology. It replaces the secondary sedimentation tank in the traditional process and can efficiently separate solid and liquid to obtain stable reclaimed water that can be directly used. The existing MBR sewage treatment membrane, as a filtering medium, is prone to clogging during filtration, and the water passing through the membrane gradually decreases with the operation time, affecting the sewage treatment effect and quality.

[0003] Chinese Patent Publication No. CN214087891U discloses an MBR membrane buried integrated sewage treatment device, including a sewage treatment tank. Aerobic tanks are arranged on the front side inside the sewage treatment tank. Anaerobic tanks are arranged inside the sewage treatment tank and behind the aerobic tanks. An MBR membrane tank is arranged inside the sewage treatment tank and behind the anaerobic tanks. An MBR membrane is arranged inside the MBR membrane tank. A tank cover is arranged on the upper side of the sewage treatment tank. An inlet is arranged above the front of the sewage treatment tank. A first inspection port is arranged on the front side of the top of the tank cover. A second inspection port is arranged on the top of the tank cover and behind the first inspection port. A third inspection port is arranged on the top of the tank cover and behind the second inspection port. A chute is opened on the inner side wall of the MBR membrane tank. A slider is arranged inside the chute. A connecting frame is arranged on the front of the slider. Cleaning brushes are evenly arranged on the front of the connecting frame. A driving motor is arranged on the top of the tank cover and behind the third inspection port. A threaded rod is arranged on the lower side of the driving motor and penetrates through the connecting frame. An outlet is arranged behind the rear side of the sewage treatment tank on the right side.

[0004] The above solution cleans the MBR membrane through cleaning brushes, but it is easy to damage the MBR membrane during the cleaning process. The existing common cleaning method is to arrange an air diffuser pipe below the MBR membrane, and blow high-pressure gas towards the MBR membrane through the air diffuser pipe to remove the sludge attached to the MBR membrane. However, no matter how it is removed, the MBR membrane needs to be replaced after being used for a period of time. When replacing, a hoisting device is required to hoist the MBR membrane, and the hoisting time is relatively long. When installing the MBR membrane, it is necessary to manually position the MBR membrane, with high working intensity and low efficiency. Summary of the Invention

At the same time, since the staff do not need to take out the membrane assemblies one by one during unloading, not only the workload of the staff is reduced, but also the work efficiency during unloading is improved. Moreover, since each lifting frame can only be lifted and lowered in the vertical direction, there is no need to individually position each membrane assembly after loading, thereby improving the loading efficiency.

[0009] Preferably, a locking groove is vertically provided on the rotating frame, and a locking rod is movably provided on the lifting frame along the vertical direction, and the locking rod is plugged and matched with the locking groove when the lifting frame is raised or lowered.

[0010] Preferably, a trigger rod is arranged in parallel on one side of the locking rod and moves synchronously with the locking rod, and an extension plate is fixed horizontally on the side wall of the treatment pool. When the lifting frame rises to the highest position, the trigger rod contacts the extension plate and slides into the lifting frame, and the locking rod slides out of the locking groove.

[0011] Preferably, the horizontal area of ​​all lifting racks located in the treatment tank is the same as the horizontal area inside the treatment tank.

[0012] Preferably, a protection unit is provided on the side wall of the processing pool, and the protection unit includes a slide groove horizontally opened on the side wall of the processing pool, a telescopic plate is horizontally slidably arranged in the slide groove, and a plurality of first one-way teeth are evenly fixed in the vertical direction at one end of the telescopic plate facing the inner side of the processing pool, and there is a gap between the telescopic plate and the bottom of the slide groove, and a second spring is horizontally arranged in the gap.

[0013] Preferably, when the receiving unit is in a material unloading state, the lifting frame is received by the uppermost first one-way teeth.

[0014] Preferably, a damping plate is slidably arranged on the upper part of the rotating frame along the height direction of the rotating frame, a second one-way tooth is arranged on the lower part of the damping plate, the second one-way tooth is unidirectionally meshed with the upper part of the membrane assembly, and an electromagnet is arranged above the damping plate which can attract the damping plate when energized.

[0015] The present invention also relates to an MBR integrated sewage treatment process, which uses an MBR integrated sewage treatment equipment, and the specific steps are as follows: S1. When installing the membrane assembly, first raise the lifting frame to the highest position. At this time, the rotating frame is in a vertical state and the end surface of the rotating frame used to receive the membrane assembly is coplanar with the upper end surface of the treatment tank. Push the membrane assembly horizontally into the rotating frame from one side of the rotating frame, and then the lifting frame drives the membrane assembly and the rotating frame to descend into the treatment tank; S2. When the membrane assembly needs to be replaced, the lifting frame rises to the highest position again, and then the driving unit drives the rotating frame to rotate and tilt, and the membrane assembly in the rotating frame slides out automatically, completing the unloading; S3, the driving unit then drives the rotating frame to return to a vertical state, waiting for new membrane components to be loaded.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

At the same time, since the staff does not need to take out the membrane assemblies one by one during unloading, not only the workload of the staff is reduced, but also the work efficiency during unloading is improved. Moreover, since each lifting frame can only be lifted and lowered in a vertical direction, there is no need to individually position each membrane assembly after loading, thereby improving the loading efficiency.

[0017] 2. By making the horizontal area of all the lifting frames in the treatment pool the same as the horizontal area inside the treatment pool, and since the lifting frame itself has a certain thickness, when the lifting frame rises to the highest position, although the trigger rod contacts the extension plate and the locking rod slides out of the locking groove, the lifting frame will not tilt downward due to the separation of the locking rod from the locking groove. At the same time, the position of each lifting frame that rises and falls in the treatment pool remains fixed, avoiding the situation of positioning the membrane module on a single lifting frame after feeding, improving work efficiency. By respectively arranging the locking rod and the locking groove on the lifting frame and the rotating frame, it is avoided that the rotating frame rotates slightly under the action of water flow during the subsequent wastewater treatment process.

Specific embodiments

[0031] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 : An MBR integrated sewage treatment device, including a treatment tank 1; a receiving unit 2 is arranged in the treatment tank 1. The receiving unit 2 includes a lifting frame 21 that is movably arranged vertically in the treatment tank 1. A rotating frame 22 for receiving the membrane module 3 is hinged on the lifting frame 21. A driving unit 23 for driving the rotation of the rotating frame 22 is arranged on the rotating frame 22. The receiving unit 2 has a blanking state and a working state. When the receiving unit 2 is in the blanking state, the rotating frame 22 is in an inclined state, and the membrane module 3 slides out of the rotating frame 22. When the receiving unit 2 is in the working state, the rotating frame 22 is in a vertical state, and the membrane module 3 is located inside the rotating frame 22.

[0033] During the sewage treatment process, the MBR membrane module 3 is one of the commonly used filtration modules. For the convenience of description, the MBR membrane module 3 will be simply referred to as the membrane module 3 in the following description. After being filtered by the membrane module 3, the suspended solids and turbidity of the wastewater are close to zero and can be directly reused. However, after long-term use, a large amount of impurities will adhere to the membrane module 3. Although there is an aeration pipeline to regularly aerate and clean the membrane module 3, the membrane module 3 still needs to be removed and replaced after long-term use. The existing membrane module 3 is relatively large in volume, and the unloading and installation efficiency is slow. During the existing process of loading and unloading the membrane module 3, a crane is usually required to lift the membrane module 3. However, during the lifting process, the position of a single membrane module 3 cannot be located, and it is necessary for workers to manually locate the specific position of each membrane module 3. This is because the internal space of the treatment tank 1 for placing the membrane module 3 is limited. If an individual membrane module 3 deviates, it will cause the subsequent membrane modules 3 to be unable to be smoothly placed into the treatment tank 1. Therefore, the efficiency is low during the above installation process. In order to overcome the above problems, there is also a device in the prior art that can drive the membrane module 3 to automatically lift and lower from the treatment tank 1. However, the volume of the device is usually large, occupying more internal space in the treatment tank 1, which in turn reduces the number of membrane modules 3 that can be placed in the treatment tank 1. And although the automatic lifting unit 4 can avoid positioning the membrane module 3 when driving the membrane module 3 to lift and lower, it is relatively laborious to unload the membrane module 3. This is because when the automatic lifting unit 4 drives the membrane module 3 to rise to the highest position, the membrane module 3 always remains in a vertical state, that is, the membrane module 3 will not be automatically discharged, but requires workers to manually pull it out. During the operation, the workers will stand on one side of the membrane module 3. If the automatic lifting component fails during the operation, the safety hazard is relatively large.

[0034] In order to avoid the above situation, the structure and working principle of the existing MBR integrated sewage treatment equipment are redesigned, so that the membrane module 3 can be automatically discharged when it is lifted out of the treatment tank 1, avoiding workers from reaching into the working area of the automatic lifting unit 4 when taking out the membrane module 3, and ensuring the personal safety of the workers. The specific structure and working process of the MBR integrated sewage treatment equipment of the present invention are as follows: An automatic lifting unit 4 is provided at the upper part of the lifting frame 21, and the automatic lifting unit 4 is used to drive the lifting frame 21 to move in the vertical direction. The rotating frame 22 has three states: loading, unloading, and working. When the rotating frame 22 is in the loading state and the working state, it is in the vertical state, that is, the rotating frame 22 does not tilt. Only when the rotating frame 22 is in the unloading state, the rotating frame 22 tilts. First, the automatic lifting assembly is used to lift the lifting frame 21 to the highest position. At this time, the end face of the rotating frame 22 for placing the membrane module 3 is coplanar with the upper end face of the treatment tank 1. The rotating frame 22 is in the vertical state at this time. Then, the membrane module 3 is horizontally pushed into the rotating frame 22 from one side of the rotating frame 22. When it is confirmed that the membrane module 3 is completely pushed into the rotating frame 22, the staff starts the automatic lifting unit 4. The automatic lifting unit 4 drives the lifting frame 21 and the rotating frame 22 to descend synchronously. When the lifting frame 21 descends to the lowest position, at this time, the lifting frame 21 is completely located inside the treatment tank 1. When wastewater is injected into the treatment tank 1, the wastewater can completely submerge the rotating frame 22. After long-term use, when the membrane module 3 needs to be replaced, the lifting frame 21 is lifted by the automatic lifting unit 4, so that the lifting frame 21 rises to the highest position. Then, the driving unit 23 is started, and the rotating frame 22 rotatably arranged on the lifting frame 21 starts to rotate under the action of the driving unit 23. As the rotating frame 22 rotates and tilts, the membrane module 3 located inside the rotating frame 22 slides out of the rotating frame 22. In this way, the purpose of automatically unloading the membrane module 3 during unloading is realized, avoiding the staff's body from reaching into the interior of the automatic lifting equipment when unloading the membrane module 3, ensuring the personal safety of the staff. At the same time, there is no need for the staff to take out the membrane module 3 one by one, reducing the workload of the staff.

[0035] By providing a lifting frame 21 that moves in the vertical direction and a rotating frame 22 hinged on the lifting frame 21, the rotating frame 22 rotates and tilts when in the unloading state, and is in the vertical state in the loading state and the working state, so that the rotating frame 22 can automatically unload the membrane module 3 in the unloading state, avoiding the staff's body from reaching into the working area of the automatic lifting unit 4 when manually unloading the membrane module 3, ensuring the personal safety of the staff. At the same time, during unloading, since there is no need for the staff to take out the membrane module 3 one by one, not only the workload of the staff is reduced, but also the working efficiency during unloading is improved. And because each lifting frame 21 can only lift and lower in the vertical direction, there is no need to separately position each membrane module 3 after loading, improving the loading efficiency.

[0036] Refer to Figure 5: The driving unit 23 includes an arc-shaped sleeve 231 fixedly arranged on the rotating frame 22. The center of the arc-shaped sleeve 231 coincides with the hinge point between the rotating frame 22 and the lifting frame 21. A pressing rod 232 is slidably arranged in the arc-shaped sleeve 231. When the end of the pressing rod 232 extends, it can contact the upper end surface of the lifting frame 21. A first pump body 233 for driving the pressing rod 232 to move is arranged at the end of the arc-shaped sleeve 231.

[0037] The first pump body 233 can be selected as an air pump or a hydraulic pump according to actual needs. When the lifting frame 21 rises to the highest position, at this time, the end surface of the rotating frame 22 for receiving the membrane module 3 is coplanar with the upper end surface of the treatment tank 1. The first pump body 233 is started, and the pressing rod 232 located in the arc-shaped sleeve 231 slides out of the arc-shaped sleeve 231 and presses on the upper end surface of the lifting frame 21. As the pressing rod 232 extends, the rotating frame 22 starts to rotate and tilt on the lifting frame 21, and the membrane module 3 located in the rotating frame 22 gradually slides out.

[0038] Refer to Figure 1 、 Figure 2 and Figure 6 : An automatic lifting unit 4 capable of driving the rotating frame 22 and the lifting frame 21 to lift synchronously is arranged on the upper part of the rotating frame 22. The automatic lifting unit 4 includes a traction rope 41 fixedly connected to the upper part of the rotating frame 22. A locking unit 42 capable of locking the rotating frame 22 in a vertical state is arranged on the lifting frame 21.

[0039] The automatic lifting unit 4 further includes a winding machine 43 arranged above the treatment tank 1. The traction rope 41 is wound in the winding machine 43. When the winding machine 43 winds up the traction rope 41, the lifting frame 21 rises under the traction of the traction rope 41. When the winding machine 43 releases the traction rope 41, the lifting frame 21 gradually descends. During the lifting and descending process of the lifting frame 21, the rotating frame 22 and the lifting frame 21 are locked by the locking unit 42. Only when the lifting frame 21 rises to the highest position, the locking unit 42 will unlock itself.

[0040] Refer to Figure 7 : A locking groove is vertically opened on the rotating frame 22. A locking rod 421 is movably arranged along the vertical direction on the lifting frame 21. The locking rod 421 is inserted and matched with the locking groove when the lifting frame 21 rises and falls.

[0041] Refer to Figure 7 and Figure 12 : A trigger rod 422 moving synchronously with the locking rod 421 is arranged in parallel on one side of the locking rod 421. An extension plate 423 is horizontally and fixedly arranged on the side wall of the treatment tank 1. When the lifting frame 21 rises to the highest position, the trigger rod 422 contacts the extension plate 423 and slides into the lifting frame 21, and the locking rod 421 slides out of the locking groove.

[0042] A lifting plate 425 is fixedly provided at the bottom of the trigger rod 422 to which the locking rod 421 is fixedly connected. A first spring 424 is provided at the lower part of the lifting plate 425. When the lifting frame 21 is in the lifting process, the first spring 424 is in a non-compressed state, and the locking rod 421 is inserted into the locking groove. Since the locking rod 421 locks the locking groove, when wastewater is injected into the treatment tank 1, the rotating frame 22 will not rotate due to the flow of wastewater. When the lifting frame 21 is at the highest position, the upper end of the trigger rod 422 is in contact with the extension plate 424. The bottom of 423 contacts and is pressed into the lifting frame 21 by the extension plate 423. At this time, the first spring 424 is in a compressed state, and the locking rod 421 slides out of the locking groove. After the driving unit 23 is started, it can normally drive the rotating frame 22 to rotate. When the loading is completed, the automatic lifting unit 4 starts to drive the rotating frame 22 to descend. As the rotating frame 22 descends, the trigger rod 422 breaks away from the contact with the extension plate 423. Under the action of the first spring 424, the locking rod 421 slides back into the locking groove, and the locking rod 421 is plugged into the locking groove.

[0043] Reference Figures 1 - 12 : The horizontal area of ​​all lifting racks 21 located in the treatment pool 1 is the same as the horizontal area inside the treatment pool 1.

[0044] Since the horizontal area of ​​all the lifting frames 21 in the treatment pool 1 is the same as the horizontal area inside the treatment pool 1, and the lifting frames 21 themselves have a certain thickness, when the lifting frames 21 rise to the highest position, although the trigger rod 422 contacts the extension plate 423 to make the locking rod 421 slide out of the locking groove, the lifting frames 21 will not rotate downward due to the separation of the locking rod 421 from the locking groove. This is because the side walls of the lifting frames 21 abut against and slide with the side walls of the treatment pool 1, and at the same time, the position of each lifting frame 21 lifted in the treatment pool 1 is fixed, thereby avoiding the need to position the membrane assembly 3 on a single lifting frame 21 after loading, thereby improving work efficiency.

[0045] Reference Figure 3 , Figure 11 and Figure 12 A protection unit 5 is arranged on the side wall of the treatment tank 1, and the protection unit 5 includes a slide groove 51 horizontally opened on the side wall of the treatment tank 1, a telescopic plate 52 is horizontally slidably arranged in the slide groove 51, and a plurality of first one-way teeth 53 are evenly fixed in the vertical direction at one end of the telescopic plate 52 facing the inner side of the treatment tank 1, and there is a gap between the telescopic plate 52 and the bottom of the slide groove 51, and a second spring 54 is horizontally arranged in the gap.

[0046] A plurality of first one-way teeth 53 are provided on the telescopic plate 52 to ensure that the lifting frame 21 can pass through the first one-way teeth 53 in sequence during the rising process. When the traction rope 41 breaks, the first one-way teeth 53 can limit the falling distance of the lifting frame 21, thereby preventing the lifting frame 21, the rotating frame 22 and the membrane assembly 3 from falling from a height and being damaged.

[0047] Reference Figure 4 and Figure 6 When the receiving unit 2 is in the unloading state, the lifting frame 21 is received by the uppermost first one-way teeth 53 .

[0048] When the receiving unit 2 is in the unloading state, the upper end surface of the lifting frame 21 contacts the lower end surface of the extension plate 423, and the lower end surface of the lifting frame 21 is received by the first one-way tooth 53 of the uppermost layer on the telescopic plate 52. That is, the lifting frame 21 is in a stuck state at this time, and the traction rope 41 is in a non-stressed state, which ensures that the lifting frame 21 will not fall suddenly when the staff installs the membrane assembly 3, thereby ensuring the safety during loading. A bellows 55 is also provided in the slide groove 51, and the two ends of the bellows 55 are fixedly connected to the telescopic plate 52 and the bottom of the slide groove 51 respectively, and a second pump body 56 is provided at one end of the bellows 55, and the second pump body 56 is preferably an air pump. When the loading is completed, the lifting frame 21 needs to be lowered, the second pump body 56 extracts the air in the bellows 55, the second spring 54 is compressed, and the telescopic plate 52 slides into the slide groove 51, and the first one-way tooth 53 is disengaged from the bottom of the lifting frame 21, and the lifting frame 21 can be smoothly lowered. Since the horizontal area of ​​all the lifting frames 21 located in the treatment pool 1 is the same as the horizontal area inside the treatment pool 1, and the lifting frame 21 itself has a certain thickness, the lifting frame 21 will not rotate downward because the locking rod 421 is disengaged from the locking groove and the first one-way tooth 53 is disengaged from the support for the lifting frame 21, that is, the lower end surface of the lifting frame 21 is always in a horizontal state.

[0049] Reference Figure 9 A damping plate 222 is slidably provided at the upper part of the rotating frame 22 along the height direction of the rotating frame 22, a second one-way tooth is provided at the lower part of the damping plate 222, the second one-way tooth is unidirectionally meshed with the upper part of the membrane assembly 3, and an electromagnet 221 is provided above the damping plate 222 which can attract the damping plate 222 after power is turned on.

[0050] By setting the damping plate 222, the membrane module 3 pushed into the rotating frame 22 will not slide out of the rotating frame 22 during the process of descending into the treatment tank 1. At the same time, during the subsequent process, the membrane module 3 will not slide out of the rotating frame 22 due to the action of water flow. When the membrane module 3 needs to be replaced, the electromagnet 221 is energized, and the electromagnet 221 attracts the damping plate 222, causing the damping plate 222 to disengage from the upper part of the membrane module 3. In this way, when the rotating frame 22 is tilted, the membrane module 3 can smoothly slide out of the rotating frame 22.

[0051] Refer to Figures 1 - 12 : The present invention also relates to an MBR integrated sewage treatment process, which uses an MBR integrated sewage treatment device. The specific steps are as follows: S1. When installing the membrane module 3, first raise the lifting frame 21 to the highest position. At this time, the rotating frame 22 is in a vertical state, and the end face of the rotating frame 22 for receiving the membrane module 3 is coplanar with the upper end face of the treatment tank 1. Push the membrane module 3 horizontally into the rotating frame 22 from one side of the rotating frame 22, and then the lifting frame 21 drives the membrane module 3 and the rotating frame 22 to descend into the treatment tank 1. S2. When the membrane module 3 needs to be replaced as required during use, the lifting frame 21 rises to the highest position again, and then the driving unit 23 drives the rotating frame 22 to rotate and tilt. The membrane module 3 located in the rotating frame 22 slides out by itself to complete the blanking. S3. Then the driving unit 23 drives the rotating frame 22 to rotate and reset to the vertical state, waiting for the feeding of a new membrane module 3.

[0052] Working principle: The rotating frame 22 has three states: loading, unloading, and working. When the rotating frame 22 is in the loading state and the working state, it is in a vertical state, that is, the rotating frame 22 does not tilt. Only when the rotating frame 22 is in the unloading state does the rotating frame 22 tilt. First, the lifting frame 21 is lifted to the highest position by the automatic lifting component. At this time, the end face of the rotating frame 22 for placing the membrane module 3 is coplanar with the upper end face of the treatment tank 1. The rotating frame 22 is in a vertical state at this time. Subsequently, the membrane module 3 is horizontally pushed into the rotating frame 22 from one side of the rotating frame 22. When it is confirmed that the membrane module 3 is completely pushed into the rotating frame 22, the staff starts the automatic lifting unit 4. The automatic lifting unit 4 drives the lifting frame 21 and the rotating frame 22 to descend synchronously. When the lifting frame 21 descends to the lowest position, at this time, the lifting frame 21 is completely located inside the treatment tank 1. When wastewater is injected into the treatment tank 1, the wastewater can completely submerge the rotating frame 22. After long-term use, when the membrane module 3 needs to be replaced, the lifting frame 21 is lifted by the automatic lifting unit 4 so that the lifting frame 21 rises to the highest position. Subsequently, the driving unit 23 is started. The rotating frame 22 rotatably provided on the lifting frame 21 starts to rotate under the action of the driving unit 23. As the rotating frame 22 rotates and tilts, the membrane module 3 located inside the rotating frame 22 slides out of the rotating frame 22. In this way, the purpose of automatically unloading the membrane module 3 during unloading is achieved, avoiding the staff's body from reaching into the interior of the automatic lifting equipment when unloading the membrane module 3, ensuring the personal safety of the staff, and at the same time, there is no need for the staff to take out the membrane module 3 one by one, reducing the workload of the staff.
