Description

Technical Field

[0001] The present invention relates to the technical field of rural domestic sewage filtration, in particular to a rural domestic sewage filtration treatment device. Background Art

[0002] Rural domestic sewage refers to the various types of sewage generated by rural residents in their daily lives, mainly including toilet sewage and miscellaneous domestic drainage. Toilet sewage generally refers to the high-concentration domestic sewage generated by human excretion and flushing of feces, while miscellaneous domestic drainage includes washing water, bathing water, kitchen drainage, and cleaning water.

[0003] Rural domestic sewage needs to be treated before it is transmitted and discharged. Currently, filter membranes are usually used to filter sewage. After the sewage passes through the filter membrane, the internal impurities will be intercepted for centralized treatment. However, when the impurities adhere to the surface of the filter membrane, it will affect the filtering effect of the filter membrane and the fluidity of the sewage. When the fluidity of the filter membrane is affected, the impact pressure of the sewage on the filter membrane will increase, and the pressure can easily cause the filter membrane to be damaged.

[0026] The present invention has the following beneficial effects:

[0027] The present invention transmits rural domestic sewage to the interior of the treatment pool through an inlet pipe, and the ultrafiltration membrane will filter the sewage entering the treatment pool, intercept and treat larger particles in the sewage through the ultrafiltration membrane, filter the sewage for a second time through the microfiltration membrane, and filter the sewage for a third time through the nanofiltration membrane. The bacteria and other impurities in the sewage are separated and treated by the microfiltration membrane and the nanofiltration membrane, thereby realizing multiple filtration operations on the sewage, thereby achieving the purification effect of rural domestic sewage, and the treated sewage will be discharged through the transmission pipe, which is convenient for the next step of treatment of the filtered sewage. A frame is provided on the surface of the ultrafiltration membrane, the microfiltration membrane and the nanofiltration membrane, and the frame is inserted into the interior of the sliding plate through the connection of the mounting plate and the connecting plate, and the sliding plate is used to limit the frame, thereby improving the stability of the ultrafiltration membrane, the microfiltration membrane and the nanofiltration membrane during the filtration operation, and the connecting plate and the sliding plate are plug-in settings, which is convenient for taking out the frame from the interior of the treatment pool for replacement.

[0028] When the present invention needs to maintain and replace the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane, the hydraulic rod is started to push the connecting plate upward. The connecting plate will pull the top plate upward when moving. At this time, the top plate will pull the frame to move toward the top outer end of the treatment tank through the positioning component, and separate from the bottom plate during the movement. At this time, there will be a distance between the frame and the bottom plate, which is convenient for taking the frame out from the inside of the positioning component for replacement, thereby improving the convenience of replacing the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane. When the telescopic rod is extended to the limit, the telescopic rod will push the bottom plate upward as the top plate moves. When the bottom plate moves The impurities inside the treatment pool will be pushed out so that the impurities after filtration can be centrally treated, thereby improving the convenience of the treatment pool for sewage treatment. The bottom plate slides on the surface of the stabilizing plate through a slide to improve the stability of the bottom plate during operation. A baffle is provided on the top of the bottom plate, and the baffle is used to limit and fix the bottom of the frame to improve the stability of the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane during filtration operation. A through-hole plate is provided on the top of the bottom plate, and the through-hole plate is used to intercept some larger impurities. At the same time, it can prevent the sewage entering the treatment pool from impacting the ultrafiltration membrane and causing damage to it, thereby improving the service life of the ultrafiltration membrane.

[0029] When the frame needs to be disassembled, the present invention pushes the inclined plate to squeeze the spring to move toward the inside of the slide frame, and the inclined plate will be separated from the inner wall of the frame. At this time, the frame can be pulled out from the inside of the mounting frame to be replaced. When the frame needs to be installed inside the mounting frame, the frame is directly pushed to move toward the inside of the mounting frame. At this time, the frame will use the inclined surface of the inclined plate to squeeze it to move toward the inside of the slide frame. When the top of the frame contacts the top of the inner wall of the mounting frame, the inclined plate will use the elasticity of the spring to enter the inside of the frame to limit and fix it. When the inclined plate contacts the inner wall of the frame, its replacement can be completed, thereby improving the convenience of disassembly and installation of ultrafiltration membranes, microfiltration membranes and nanofiltration membranes.

[0030] The ultrafiltration membrane, microfiltration membrane and nanofiltration membrane of the present invention start the power device to drive the threaded rod to start operation during the operation, the threads inside the two screw hole frames are arranged in opposite directions, and the bottom of the movable plate contacts the top of the bottom plate. At this time, the movable plate cooperates with the bent frame and the round rod to limit the screw hole frames. When the threaded rod rotates, it pushes the two screw hole frames to move away from or close to each other. When the movable plate moves, it pushes the scraper to clean the surface of the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane through the sliding rod to avoid the accumulation of filtered impurities on the surface of the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane to affect their fluidity. The scraper After the filter membrane, microfiltration membrane and nanofiltration membrane are cleaned, the pressure of sewage on them will be reduced, avoiding the increase of pressure of sewage on the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane due to the accumulation of impurities, and improving the service life of the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane. The scraper uses the elasticity of the elastic rod to maintain contact with the surface of the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane, avoiding the deformation of the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane due to the pressure of sewage, which affects the use effect of the scraper. Cleaning the ultrafiltration membrane, microfiltration membrane and nanofiltration membrane with the scraper will improve their fluidity, thereby increasing the filtration effect on sewage.

[0031] When the two screw hole racks of the present invention move away from each other, the ends of the opening and closing plates will be pulled to move by the shaft rod. When the ends of the two opening and closing plates move away from each other, the hinge rod will be pulled to move upward. When the hinge rod moves upward, it pushes the triangle plate to move on the surface of the through-hole plate. The surface of the through-hole plate is cleaned by the triangle plate to prevent larger impurities from accumulating on the surface of the through-hole plate and causing blockage. The stabilizing rack will limit the triangle plate to improve the stability of the triangle plate when moving. When the two screw hole racks move closer to each other, the triangle plate will move downward, so that the triangle plate can move back and forth on the surface of the through-hole plate, thereby improving the cleaning effect of the through-hole plate.

The bacteria and other impurities in the sewage are separated and treated by the microfiltration filter membrane 21 and the nanofiltration filter membrane 23, thereby realizing multiple filtration operations on the sewage, thereby achieving the purification effect of rural domestic sewage. The treated sewage will be discharged through the transmission pipe 4, which is convenient for the next step of treatment of the filtered sewage. On the surface of the ultrafiltration filter membrane 22, the microfiltration filter membrane 21 and the nanofiltration filter membrane 23 are provided A frame 20 is provided, and the frame 20 is inserted into the interior of the sliding plate 25 through the connection between the mounting plate 24 and the connecting plate 26. The sliding plate 25 is used to limit the frame 20, thereby improving the stability of the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23 during the filtration operation. The connecting plate 26 and the sliding plate 25 are plug-in settings, which makes it convenient to take out the frame 20 from the interior of the treatment tank 1 for replacement. When the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23 need to be maintained and replaced, the hydraulic rod 3 is started to push the connecting plate 5 upward. When the connecting plate 5 moves, it will pull the top plate 31 upward. At this time, the top plate 31 will pull the frame 20 to the top outer end of the treatment tank 1 through the positioning component 8, and in the process of moving, it will be in contact with the bottom plate 31. 34 is separated. At this time, there will be a distance between the frame 20 and the bottom plate 34, which is convenient for taking out the frame 20 from the inside of the positioning component 8 for replacement, thereby improving the convenience of replacing the ultrafiltration filter membrane 22, the microfiltration filter membrane 21 and the nanofiltration filter membrane 23. When the telescopic rod 32 is extended to the limit, the telescopic rod 32 will push the bottom plate 34 upward with the movement of the top plate 31. The bottom plate 34 will push out the impurities inside the treatment tank 1 when moving, so as to centrally treat the impurities after filtration, thereby improving the convenience of the treatment tank 1 for sewage treatment. The bottom plate 34 slides on the surface of the stabilizing plate 30 through the slide 38, thereby improving the stability of the bottom plate 34 during operation. A baffle 36 is provided on the top of the bottom plate 34, and the baffle 36 is used to stabilize the bottom of the frame 20 The limiting fixation improves the stability of the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23 during the filtering operation. A through-hole plate 33 is provided on the top of the bottom plate 34. The through-hole plate 33 is used to intercept some larger impurities. At the same time, it can prevent the sewage entering the treatment tank 1 from impacting the ultrafiltration membrane 22 and causing damage to it, thereby improving the service life of the ultrafiltration membrane 22. When it is necessary to disassemble the frame 20, push the inclined plate 43 to squeeze the spring 44 to move toward the inside of the slide frame 45, and the inclined plate 43 will be separated from the inner wall of the frame 20. At this time, the frame 20 can be pulled out from the inside of the mounting frame 41 for replacement. When it is necessary to install the frame 20 inside the mounting frame 41, directly push the frame 20 to move toward the inside of the mounting frame 41.At this time, the frame 20 will use the inclined surface of the inclined plate 43 to squeeze it to move toward the inside of the slide frame 45. When the top of the frame 20 contacts the top of the inner wall of the mounting frame 41, the inclined plate 43 will use the elasticity of the spring 44 to enter the interior of the frame 20 to limit and fix it. When the inclined plate 43 contacts the inner wall of the frame 20, its replacement can be completed, improving the convenience of disassembly and installation of the ultrafiltration filter membrane 22, microfiltration filter membrane 21 and nanofiltration filter membrane 23. During the operation, the ultrafiltration filter membrane 22, microfiltration filter membrane 21 and nanofiltration filter membrane 23 start the power device 51 to drive the threaded rod 56 to start operation. The threads inside the two screw hole frames 59 are set in opposite directions, and the bottom of the movable plate 54 is in contact with the inner wall of the frame 20. When the top of the bottom plate 34 is in contact, the movable plate 54 cooperates with the bent frame 55 and the round rod 52 to limit the screw hole frame 59. When the threaded rod 56 rotates, it will push the two screw hole frames 59 to move away from or closer to each other. When the movable plate 54 moves, it will push the scraper 53 through the slide bar 57 to clean the surface of the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23 to avoid the accumulation of filtered impurities on the surface of the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23 to affect their fluidity. After the scraper 53 completes the cleaning of the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23, the pressure of the sewage on them will be reduced, avoiding ultrafiltration. The accumulation of impurities in the membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23 causes the pressure of sewage on them to increase, thereby improving the service life of the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23. The scraper 53 uses the elasticity of the elastic rod 58 to maintain contact with the surface of the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23, thereby preventing the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23 from being deformed due to the pressure of sewage and affecting the use effect of the scraper 53. The scraper 53 cleans the ultrafiltration membrane 22, the microfiltration membrane 21 and the nanofiltration membrane 23, thereby improving their fluidity and increasing the filtering effect on the sewage. The two screw hole frames 59 move away from each other. When the screw hole brackets 59 move, the ends of the opening and closing plates 64 are pulled to move by the shaft 60. When the ends of the two opening and closing plates 64 move away from each other, the hinge rod 63 is pulled upward. When the hinge rod 63 moves upward, it pushes the triangular plate 61 to move on the surface of the through-hole plate 33. The triangular plate 61 is used to clean the surface of the through-hole plate 33 to prevent large impurities from accumulating on the surface of the through-hole plate 33 and causing blockage. The stabilizing frame 62 limits the triangular plate 61 to improve the stability of the triangular plate 61 during movement. When the two screw hole brackets 59 move closer to each other, the triangular plate 61 will move downward, so that the triangular plate 61 can move back and forth on the surface of the through-hole plate 33, thereby improving the cleaning effect of the through-hole plate 33.
