[0002] Landfill leachate membrane treatment is a highly efficient and environmentally friendly wastewater treatment technology, primarily used in the purification of leachate from landfills and incinerators. Landfill leachate has a complex composition, containing high concentrations of organic matter, heavy metals, ammonia nitrogen, and other pollutants, which traditional treatment methods struggle to completely remove. Membrane treatment technology utilizes membranes with specific pore sizes as a barrier through physical separation to precisely trap pollutants. Common membrane treatment processes include microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. These processes purify the leachate step-by-step based on pore size and separation mechanisms. When using membrane treatment for leachate for extended periods, membrane cleaning is necessary to maintain treatment efficiency.

[0003] A search revealed a Chinese patent publication number CN 217829061 U, which discloses a landfill leachate membrane treatment device, including a filter box. An inlet pipe is provided on the left side of the filter box, a cleaning pipe is provided on the top of the filter box, and an outlet pipe is provided on the right side of the filter box. A filter frame is provided inside the filter box, and a circular mesh is embedded in the filter frame. A drive mechanism is installed on the top of the filter box, and a cleaning mechanism is connected to the drive mechanism.

[0004] To address the problem that the above-mentioned technologies require machine shutdown and disassembly for filter membrane cleaning, which affects the efficiency of landfill leachate treatment, a landfill leachate membrane treatment device is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a landfill leachate membrane treatment device to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: a landfill leachate membrane treatment device includes an inlet and an outlet pipe. A diversion pipe is fixedly connected below the inlet, and an adjustment component is fixedly connected to one side of the outlet pipe. A filter membrane support is fixedly connected to one end of the adjustment component. A lifting groove is opened inside the diversion pipe. A limit plate is slidably connected to the lower end of the lifting groove, and a lifting component is fixedly connected above the limit plate.

[0007] In some embodiments, the lifting assembly includes an electric push rod and a lifting rod. One side of the electric push rod is fixedly connected to the diversion pipe, the upper end of the lifting rod is fixedly connected to the movable end above the electric push rod, and the lower end of the lifting rod is fixedly connected to a limit plate.

[0008] In some embodiments, the adjustment assembly includes an adjustment motor and a rotating bracket, wherein the adjustment motor is fixedly connected to one side of the splitter pipe, and the rotating bracket is fixedly connected to the power output shaft of the adjustment motor.

[0009] In some embodiments, a filter membrane is fixedly connected inside the filter membrane holder, and a docking slot is opened on one side of the filter membrane holder.

[0010] In some embodiments, a flow meter is fixedly connected below the outlet pipe, and an inlet filter plate is fixedly connected to one end of the inlet.

[0011] In some embodiments, a limit plate is fixedly connected to the inner side of the diversion pipe, and a lifting baffle is fixedly connected to one side of the lifting rod.

Landfill leachate enters from the inlet and is guided to the filter membranes on both sides for filtration through the diversion pipe. The clean liquid flows into the outlet pipe. When one side of the filter membrane needs to be cleaned, the lifting component raises the limit plate, and the adjusting motor drives the filter membrane support to rotate, moving the spare filter membrane to the working position and the original filter membrane is rotated out for replacement. The dual-position switching ensures the continuity of filtration operations and processing efficiency.

A landfill leachate membrane treatment device, wherein when the filter membrane rotates to the flushing station, the backwash pump is started, and water is supplied through the flushing water supply pipe to backwash the filter membrane. The dirt is collected with the water flow through the flushing recovery pipe. The replaceable filter membrane is physically cleaned online, which significantly reduces the replacement frequency of the filter membrane, reduces operating costs, and extends the service life of the filter membrane.

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1: As Figure 1-5 As shown, a landfill leachate membrane treatment device includes an inlet 1 and an outlet pipe 3. The outlet pipe 3 is connected to an external recycling component. A diversion pipe 2 is fixedly connected below the inlet 1. An adjustment component is fixedly connected to one side of the outlet pipe 3. A filter membrane support 10 is fixedly connected to one end of the adjustment component. A lifting groove 13 is opened inside the diversion pipe 2. A limit plate 12 is slidably connected to the lower end of the lifting groove 13. A lifting component is fixedly connected above the limit plate 12. The lifting assembly includes an electric push rod 5 and a lifting rod 7. One side of the electric push rod 5 is fixedly connected to the diversion pipe 2, the upper end of the lifting rod 7 is fixedly connected to the movable end above the electric push rod 5, and the lower end of the lifting rod 7 is fixedly connected to a limit plate 12. The adjustment assembly includes an adjustment motor 8 and a rotating bracket 9. The adjustment motor 8 is fixedly connected to one side of the diverter pipe 2, and the rotating bracket 9 is fixedly connected to the power output of the adjustment motor 8. A filter membrane 11 is fixedly connected inside the filter membrane holder 10. The filter membrane 11 can be disassembled and replaced. A docking slot 16 is opened on one side of the filter membrane holder 10. When in use, the landfill leachate is introduced from the inlet 1. Then the liquid is filtered by the filter membrane 11 at the bottom of the diversion pipes 2 on both sides and flows into the outlet pipe 3. During use, the electric push rod 5 is retracted and the lifting rod 7 is used to drive the limit plate 12 to move downward and squeeze the edge of the filter membrane support 10 to seal it. When the filter membrane 11 needs to be replaced and cleaned after a period of use, the electric push rod 5 extends, allowing the limit plate 12 to move upward. Then, the motor 8 is started, causing the rotating bracket 9 to rotate the filter membrane support 10 by 90 degrees. At this time, the new filter membrane 11 can be moved between the inlet 1 and the outlet pipe 3. Then, the electric push rod 5 retracts again, allowing the limit plate 12 to move downward, resealing the filter membrane support 10. The transferred filter membrane 11 can then be replaced or cleaned.

[0023] In this embodiment, a flow meter 4 is fixedly connected below the liquid outlet pipe 3, and a liquid inlet filter plate 6 is fixedly connected to one end of the liquid inlet 1. The flow meter 4 can be used to monitor the liquid flow rate in the outlet pipe 3, and the flow meter 4 is connected to an external control device, such as a control computer, which can monitor whether the filter membrane 11 is blocked by monitoring the liquid flow rate in the outlet pipe 3.

[0024] In this embodiment, a limiting plate 14 is fixedly connected to the inner side of the diversion pipe 2, and a lifting baffle 15 is fixedly connected to one side of the lifting rod 7. When the lifting rod 7 is raised, the lifting baffle 15 can be raised synchronously. At this time, the raised lifting baffle 15 can cooperate with the limiting plate 14 to block one side of the diversion pipe 2. After the liquid inside the diversion pipe 2 on this side is filtered, the filter membrane support 10 on the corresponding side is rotated. During this process, the landfill leachate can flow out from the diversion pipe 2 on the other side, allowing the device to clean and replace the filter membrane 11 without stopping the machine, thus improving the filtration efficiency.

[0025] In this embodiment: during use, the landfill leachate is introduced from the inlet 1, and then the liquid is filtered by the filter membrane 11 at the bottom of the diversion pipes 2 on both sides and flows into the outlet pipe 3. During use, the electric push rod 5 is retracted, and the lifting rod 7 drives the limiting plate 12 to move downward, squeezing the edge of the filter membrane support 10 to seal it. When the filter membrane 11 needs to be replaced and cleaned after a period of use, the electric push rod 5 extends, allowing the limit plate 12 to move upward. Then, the motor 8 is started, causing the rotating bracket 9 to rotate the filter membrane support 10 by 90 degrees. At this time, the new filter membrane 11 can be moved between the inlet 1 and the outlet pipe 3. Then, the electric push rod 5 retracts again, allowing the limit plate 12 to move downward, resealing the filter membrane support 10. The transferred filter membrane 11 can then be replaced or cleaned. The flow meter 4 can be used to monitor the liquid flow rate in the outlet pipe 3, and the flow meter 4 is connected to an external control device, such as a control computer, which can monitor whether the filter membrane 11 is blocked by monitoring the liquid flow rate in the outlet pipe 3. When the lifting rod 7 is raised, it can simultaneously drive the lifting baffle 15 to rise. At this time, the raised lifting baffle 15 can work with the limiting plate 14 to block one side of the diversion pipe 2. After the liquid inside the diversion pipe 2 on this side is filtered, the filter membrane support 10 on the corresponding side is rotated. During this process, the landfill leachate can flow out from the diversion pipe 2 on the other side, allowing the device to clean and replace the filter membrane 11 without stopping the machine, thus improving the filtration efficiency.

[0026] Example 2: A landfill leachate membrane treatment device. This example is an improvement on Example 1, as follows: Figure 1-5 As shown, a flushing water supply pipe 17 is fixedly connected to one side of the liquid outlet pipe 3, and a backwash pump 18 is fixedly connected to the inlet end of the flushing water supply pipe 17. A flushing and recovery pipe 19 is fixedly connected to one side of the diversion pipe 2, and the upper end of the flushing water supply pipe 17 and the lower end of the flushing and recovery pipe 19 are slidably connected to the filter membrane support 10. After the filter membrane support 10 rotates 180°, it will rotate to the middle of the flushing water supply pipe 17 and the flushing recovery pipe 19. At this time, the backwash pump 18 is started. The backwash pump 18 is connected to the external water supply pipe. Water can be sprayed from bottom to top through the flushing water supply pipe 17 to backwash and clean the filter membrane 11 in the filter membrane support 10. The flushed liquid is recovered through the flushing recovery pipe 19, which can effectively improve the service life of the filter membrane 11 and reduce costs.
