Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a novel MBR membrane component for water distribution. Background Art

[0002] MBR membrane module is an advanced water treatment equipment, which combines membrane separation technology with biotechnology to efficiently perform solid-liquid separation and sewage treatment. MBR membrane module is the core part of membrane bioreactor (Membrane Bio-Reactor, referred to as MBR), which directly places membrane modules in the bioreactor to effectively intercept and separate pollutants in sewage. This technology not only improves the efficiency and quality of sewage treatment, but also greatly saves space and reduces energy consumption, and can effectively separate suspended solids in water.

[0003] In the prior art, the collaborative work of MBR membrane components in sewage treatment is crucial. Once an abnormality occurs in one of the components, the treatment effect of the entire system will be affected, and it will be difficult to stop water distribution in time, resulting in complicated and cumbersome maintenance procedures. The design of MBR systems is usually automated and aims to continuously treat the incoming sewage. Therefore, when one or more membrane components have problems, even if the system detects the fault immediately, it does not have the ability to intelligently identify the problematic components. This means that even if a membrane component has begun to affect the overall treatment effect, the system will continue to run and cannot immediately stop water distribution for inspection and maintenance. This delayed response leads to reduced sewage treatment efficiency and even secondary pollution of the treated sewage. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a new type of MBR membrane component for water distribution.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a novel MBR membrane assembly for water distribution, comprising an MBR membrane body, a water inlet pipe is arranged on the top of the MBR membrane body, a main water pipe is fixed to one end of the water inlet pipe, a bottom truncated cone is fixed to the top of the MBR membrane body, a limited water pipe is fixed to the top of the bottom truncated cone, a water inlet pipe is fixed to the top of the water limiting pipe, a disc groove is provided on the inner wall of the bottom truncated cone, a hollow disc is fixed to the inner wall of the disc groove, an inner ring is fixed to the top of the hollow disc, an outer ring is fixed to the top of the hollow disc, through grooves are provided on the surface of the inner ring and the surface of the outer ring, The bottom of the through groove is provided with an elliptical through groove, the top of the hollow disc is rotatably connected with a power gear, the tooth groove of the power gear is meshed with a rack, the surface of the rack is slidably connected with the inner wall of the through groove, the bottom of the rack is fixed with an elliptical stopper, the surface of the elliptical stopper is slidably connected with the inner wall of the elliptical through groove, and a sealing plate is fixed on the top of the rack. In the prior art, the coordinated work of MBR membrane components in sewage treatment is very important. Once an abnormality occurs in one of the components, the treatment effect of the entire system will be affected, and it is difficult to stop water distribution in time, which makes the maintenance steps complicated and cumbersome. The system is usually designed to be automated and to continuously process the incoming sewage. Therefore, when one or more membrane components have problems, the system will not immediately detect the fault or have the ability to intelligently identify the problem components. This means that even if a membrane component has begun to affect the overall treatment effect, the system will continue to operate instead of immediately stopping water distribution for inspection and maintenance. This delayed response leads to reduced sewage treatment efficiency and even secondary pollution of the treated sewage. In response to such problems, the utility model solves the problem by installing a sheet sealing plate, so that when abnormal pollution occurs in sewage treatment, the staff can start the motor to drive the power gear to rotate clockwise, so that the power gear engages and pushes the rack to move toward the center of the hollow disc, so that the sheet sealing plates gather and cooperate, so that the hollow disc seals and closes, and the water distribution of the MBR membrane body is stopped to prevent clean water pollution. When the sheet sealing plates gather toward the center, the sheet sealing plates are pushed by the water body, and the cooperation of the elliptical limiter and the elliptical groove prevents the sheet sealing plates from shifting, maintains the precise cooperation of the components, avoids shifting and deformation, stops water distribution by closing the water inlet pipes one by one, and quickly checks the abnormalities of the system, thereby improving user experience and facilitating operation of the staff.

[0006] Preferably, the outer ring surface is provided with an arc groove array in a circumferential array, and a limiting arc is fixed at one end of the rack. In the prior art, when the rack moves toward the center of the hollow disk at a relatively high speed, if the distance the rack moves forward exceeds a predetermined interference, such excessive movement may cause collision between the sheet sealing plates, thereby causing damage thereto. Such damage may reduce the sealing performance of the sheet sealing plates, thereby affecting the sealing effect of the entire system. To address such problems, the utility model solves the problem by installing a limiting arc, so that when the rack moves to a specified position, the limiting arc prevents the rack from continuing to move forward, thereby preventing collision between the sheet sealing plates. At the same time, the arc groove may prevent the limiting arc from being higher than the outer ring surface, thereby achieving the effect of increasing the service life of the equipment.

[0007] Preferably, a bottom substrate is fixed to the bottom of the MBR membrane body. In the prior art, MBR membrane components are usually installed in a sewage pool for filtering and treating sewage. During the water inlet and outlet of the sewage pool, the thrust generated by the water flow will act on the MBR membrane components, causing them to deviate. This deviation will cause damage or even breakage of the connecting pipes, thereby affecting the normal operation of the entire sewage treatment system. To solve such problems, the utility model adopts the method of installing a bottom substrate to increase the contact area between the MBR membrane body and the bottom of the sewage pool through the bottom substrate, increase friction, and facilitate the staff to use bolts and other fixing equipment to achieve the effect of improving the stability of equipment use.

[0008] Preferably, a rubber strip is glued and fixed to the side surface of the sealing plate, and the rubber strip increases the sealing performance of the sealing plate and improves the use effect of the equipment.

[0009] Preferably, the bottom of the rack is coated with a rubber layer to increase water resistance, prevent the screws used to fix the rack and the sheet sealing plate from getting damp and rusting, and increase the service life of the equipment.

[0010] Preferably, the bottom frustum is configured as a frustum cube to improve stability and enhance component fixing effect.

[0011] Preferably, a cross anti-skid groove is provided at the bottom of the base plate to increase friction to prevent the device from slipping, relieve pressure on the fixed components, and increase the service life of the equipment.

[0012] Beneficial effects:

[0013] 1. In the prior art, the coordinated work of MBR membrane components in sewage treatment is crucial. Once an abnormality occurs in one of the components, the treatment effect of the entire system will be affected, and it is difficult to stop water distribution in time, resulting in complicated and cumbersome maintenance procedures. The design of MBR systems is usually automated, aiming to continuously treat the inflowing sewage. Therefore, when one or more membrane components have problems, the system will not immediately detect the fault, or it does not have the ability to intelligently identify the problematic components. This means that even if a membrane component has begun to affect the overall treatment effect, the system will continue to operate instead of immediately stopping water distribution for inspection and maintenance. This delayed response leads to a decrease in sewage treatment efficiency. The rate is reduced, and even secondary pollution of the treated sewage is caused. To solve this problem, the utility model adopts the method of installing a sheet sealing plate to solve it. When abnormal pollution occurs in the sewage treatment, the staff can start the motor to drive the power gear to rotate clockwise, so that the power gear engages and pushes the rack to move toward the center of the hollow disc, so that the sheet sealing plates gather and cooperate, and the hollow disc seals and closes, stopping the water distribution of the MBR membrane body to prevent clean water pollution. When the sheet sealing plates gather toward the center, the sheet sealing plates are pushed by the water body, and the cooperation of the elliptical limiter and the elliptical groove prevents the sheet sealing plates from shifting, maintains the precise cooperation of the components, avoids shifting and deformation, and achieves the effect of improving user experience and facilitating operation of the staff.

[0014] 2. In the prior art, when the rack moves toward the center of the hollow disc at a high speed, if the distance the rack moves forward exceeds the predetermined interference, this excessive movement will cause collision between the sheet sealing plates, thereby causing damage to them. This damage will reduce the sealing performance of the sheet sealing plates, thereby affecting the sealing effect of the entire system. To address this problem, the utility model solves it by installing a limiting arc, so that when the rack moves to a specified position, the limiting arc prevents the rack from moving forward and prevents collision between the sheet sealing plates. At the same time, the arc groove can prevent the limiting arc from being higher than the outer ring surface, thereby achieving the effect of increasing the service life of the equipment.

[0015] 3. In the prior art, MBR membrane components are usually installed in sewage pools for filtering and treating sewage. During the water inlet and outlet process of the sewage pool, the thrust generated by the water flow will act on the MBR membrane components, causing them to deviate. This deviation will cause damage or even breakage of the connecting pipes, thereby affecting the normal operation of the entire sewage treatment system. To solve such problems, the utility model adopts the method of installing a bottom substrate to increase the contact area between the MBR membrane body and the bottom of the sewage pool through the bottom substrate, increase friction, and facilitate the staff to use bolts and other fixing equipment to achieve the effect of improving the stability of equipment use.

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment:

[0027] Reference Figure 1-6A novel water distribution MBR membrane assembly comprises an MBR membrane body 1, a water inlet pipe 101 is arranged on the top of the MBR membrane body 1, a main water pipe 102 is fixed at one end of the water inlet pipe 101, a bottom truncated cone 201 is fixed on the top of the MBR membrane body 1, a limited water pipe 2 is fixed on the top of the bottom truncated cone 201, the water inlet pipe 101 is fixed on the top of the limited water pipe 2, a disc groove 202 is opened on the inner wall of the bottom truncated cone 201, a hollow disc 203 is fixed on the inner wall of the disc groove 202, an inner ring 204 is fixed on the top of the hollow disc 203, an outer ring 205 is fixed on the top of the hollow disc 203, and the inner ring 204 surface and the outer ring 205 surface are both opened The through groove has an elliptical groove 209 at the bottom, the top of the hollow disc 203 is rotatably connected with a power gear 208, the power gear 208 is meshed with a rack 206, the surface of the rack 206 is slidably connected to the inner wall of the through groove, an elliptical stopper 2010 is fixed at the bottom of the rack 206, the surface of the elliptical stopper 2010 is slidably connected to the inner wall of the elliptical groove 209, and a sealing plate 207 is fixed on the top of the rack 206. The coordinated work of MBR membrane components in sewage treatment is crucial. Once an abnormality occurs in one of the components, the treatment effect of the entire system will be affected, and it is difficult to stop water distribution in time, resulting in maintenance. The steps become complicated and cumbersome. The design of MBR system is usually automated, aiming to continuously treat the inflowing sewage. Therefore, when one or more membrane components have problems, the system will not detect the fault immediately, or it does not have the ability to intelligently identify the problematic components. This means that even if a membrane component has begun to affect the overall treatment effect, the system will continue to operate instead of immediately stopping water distribution for inspection and maintenance. This delayed response leads to reduced sewage treatment efficiency and even secondary pollution of the treated sewage. The installation sheet sealing plate 207 is used to solve this problem, so that when abnormal sewage treatment occurs, the system can detect the fault immediately. When there is pollution, the staff can start the motor to drive the power gear 208 to rotate clockwise, so that the power gear 208 engages and pushes the rack 206 to move toward the center of the hollow disc 203, so that the sealing plates 207 gather and cooperate, so that the hollow disc 203 is sealed and closed, and the water distribution of the MBR membrane body 1 is stopped to prevent clean water pollution. When the sealing plates 207 gather toward the center, the sealing plates 207 are pushed by the water body, and the cooperation of the elliptical limiter 2010 and the elliptical groove 209 prevents the sealing plates 207 from shifting, maintains the precise cooperation of the components, avoids shifting and deformation, and achieves the effect of improving user experience and facilitating operation of the staff.

[0028] The outer ring 205 is provided with an arc groove 3 in a circumferential array, and a limiting arc 301 is fixed at one end of the rack 206. When the rack 206 moves toward the center of the hollow disc 203 at a high speed, if the distance the rack 206 moves forward exceeds the predetermined interference, this excessive movement will cause collision between the sheet sealing plates 207, thereby causing damage to them. This damage will reduce the sealing performance of the sheet sealing plates 207, thereby affecting the sealing effect of the entire system. The problem is solved by installing a limiting arc 301, so that when the rack 206 moves to a specified position, the limiting arc 301 prevents the rack 206 from moving forward, preventing collision between the sheet sealing plates 207. At the same time, the arc groove 3 can prevent the limiting arc 301 from being higher than the surface of the outer ring 205, thereby achieving the effect of increasing the service life of the equipment. A rubber strip is glued and fixed on the side of the sheet sealing plate 207, and the rubber strip is used to increase the sealing performance of the sheet sealing plate 207 and improve the use effect of the equipment. The bottom of the rack 206 is coated with a rubber layer to increase water resistance, prevent the screws used to fix the rack 206 and the sheet sealing plate 207 from getting damp and rusting, and improve the service life of the equipment. The bottom of the MBR membrane body 1 is fixed with a bottom substrate 103. The MBR membrane assembly is usually installed in a sewage pool for filtering and treating sewage. During the water inlet and outlet of the sewage pool, the thrust generated by the water flow will act on the MBR membrane assembly, causing them to deviate. This deviation will cause damage or even breakage of the connecting pipe, thereby affecting the normal operation of the entire sewage treatment system. The bottom substrate 103 is installed to solve the problem, and the contact area between the MBR membrane body 1 and the bottom of the sewage pool is increased through the bottom substrate 103, increasing the friction force, and facilitating the use of bolts and other fixing equipment by the staff, so as to achieve the effect of improving the stability of the equipment. The bottom truncated cone 201 is set as a truncated cone cube to improve stability and increase the fixing effect of the assembly. A cross anti-skid groove is provided at the bottom of the bottom substrate 103 to increase friction and prevent equipment from slipping, relieve the pressure of the fixed assembly, and improve the service life of the equipment.

[0029] The working principle of the utility model is as follows: when abnormal pollution occurs in sewage treatment, the staff can start the motor to drive the power gear 208 to rotate clockwise, so that the power gear 208 engages and pushes the rack 206 to move toward the center of the hollow disc 203, so that the sheet sealing plates 207 gather and cooperate, so that the hollow disc 203 is sealed and closed, and the water distribution of the MBR membrane body 1 is stopped to prevent clean water pollution. When the sheet sealing plates 207 gather toward the center, the sheet sealing plates 207 are pushed by the water body, and the cooperation of the elliptical limit piece 2010 and the elliptical through groove 209 prevents the sheet sealing plate 207 from deviating. When the rack 206 moves to the specified position, the limiting arc 301 prevents the rack 206 from continuing to move forward to prevent collision between the sheet sealing plates 207. At the same time, the arc groove 3 can prevent the limiting arc 301 from being higher than the surface of the outer ring 205.

Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
