Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of leachate lifting devices, and more specifically, to a leachate lifting device. Background Art
[0002] In addition to significantly exceeding standards for pollutants such as COD, BOD, and NH3-N, raw leachate also contains halogenated aromatic hydrocarbons, heavy metals, and viruses. Therefore, raw leachate is a complex, high-concentration organic wastewater with a high pollution load and comprehensive pollution. Currently, biological denitrification and membrane treatment technologies are widely used to remove high concentrations of ammonia nitrogen. In the leachate treatment process, landfills are mostly constructed in hilly or mountainous areas. The regulating ponds that collect the leachate are generally located in low-lying areas. Due to the terrain design, some regulating ponds have vertical walls, and the depth of the regulating ponds exceeds ten meters, which is several dozen meters higher than the treatment station. To lift and transport the leachate, high-lift water pumps are required, and the addition of process water tanks is required to address the problem of insufficient suction head. This not only increases the complexity of the treatment system but also increases treatment costs. Secondly, the submersible pump of the lifting device is installed at the bottom of the regulating tank. Since the raw water of the landfill leachate contains various pollutants, these pollutants easily adhere to the surface of the submersible pump and form scale. The motor of the submersible pump with scale cannot dissipate the heat from operation in time, so the motor often burns out. However, the submersible pump is installed at the bottom of the regulating tank, and the leachate in the regulating tank cannot be completely drained. Especially when the regulating tank has collected a lot of leachate, the submersible pump cannot be repaired or replaced. The existing leachate lifting device, after working for a long time, is difficult to disassemble because the raw water of the landfill leachate contains various pollutants. These pollutants easily adhere to the surface of the leachate pipe and form scale, causing blockage. Therefore, it needs to be improved and optimized. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figures 1 to 6 As shown, the utility model provides a leachate lifting device, including a support frame 1, a grille 2 is fixedly installed inside the support frame 1, and the number of the grilles 2 is nine, a floating mechanism is fixedly installed between the grilles 2, and side beams 5 are fixedly installed on the front and rear sides of the top of the support frame 1, a support frame 2 6 is fixedly installed on the bottom of the side beam 5, a bracket 10 is fixedly installed on the top of the support frame 2 6, an electric water pump 11 is fixedly installed on the right side of the bracket 10, a connecting pipe 12 is fixedly connected to the right side of the electric water pump 11, and an inlet pipe 13 is fixedly connected to the outer surface of the connecting pipe 12 and extends to the bottom of the support frame 10. Extending into the interior of the connecting pipe 12, the bottom of the water inlet pipe 13 is fixedly sleeved with a circular ring 24, and the bottom of the circular ring 24 is rotatably installed with a circular ring 15. An arc groove 18 is opened inside the circular ring 15, and one end of the arc groove 18 is close to the outer side of the circular ring 15 and the other end is close to the inner side of the circular ring 15 toward the center. A clamping block 17 is slidably installed on the outer side of the arc groove 18. The bottom side of the circular ring 24 is located at the bottom of the circular ring 15 and is fixedly installed with a fan-shaped hollow block 21 and is located between the clamping blocks 17. The outer surface of the circular ring 15 is fixedly installed with a rotating rod 16 and extends to the outside of the circular ring 15.
[0023] After the leachate lifting device has been working for a long time, since the leachate raw water contains a variety of pollutants, and these pollutants are very easy to adhere to the surface of the leachate pipe and form scale to cause blockage, when the staff needs to replace the leachate inlet pipe, they rotate the rotating rod 16 at this time. When the rotating rod 16 starts to rotate, it will drive the ring 15 to rotate. When the ring 15 starts to rotate, it will drive the opened arc groove 18 to start rotating. When the arc groove 18 starts to rotate, the opening path of the arc groove 18 is closer and closer to the center, which will tighten the clamping block 17 toward the center. When replacement is needed, it is only necessary to rotate the rotating rod 16 in the opposite direction to quickly replace it.
[0024] By rotating the rotating rod 16, when the rotating rod 16 starts to rotate, it will drive the ring 15 to rotate, and when the ring 15 starts to rotate, it will drive the opened arc groove 18 to start rotating. When the arc groove 18 starts to rotate, the opening path of the arc groove 18 will get closer and closer to the center, which will cause the locking block 17 to tighten toward the center. Compared with traditional devices, this device can be quickly disassembled and replaced, which can greatly shorten the downtime of the equipment, so that the entire leachate treatment system can maintain stable operation, and will not affect the subsequent treatment links due to problems with the lifting device, thereby ensuring the continuity and efficiency of the treatment process, and can make the leachate lifting device have stronger adaptability and reliability when facing various uncertain factors.
[0025] Among them, the floating mechanism includes pontoons 3 fixedly installed between the grids 2, and the number of pontoons 3 is nine. The inner side of the support frame 2 6 is fixedly installed with pontoons 3 and penetrates through it. The middle bottom end of the side beam 5 is fixedly installed with a support frame 3 7 and is penetrated by the pontoons 3. The bottom of the side beam 5 is located on the right side of the support frame 3 7 and is fixedly installed with a support frame 4 8 and is penetrated by the pontoons 3. The bottom of the side beam 5 is located on the right side of the support frame 4 8 and is fixedly installed with a pontoon 3 and is penetrated by the pontoons 3.
[0026] Since the entire device is in the regulating tank during long-term operation, it is easy to cause failures and inconvenience in maintenance in the tank. Then the bottom of the side beam 5 is fixedly connected to the support frame 2 6, the bottom of the side beam 5 is fixedly connected to the support frame 3 7, the bottom of the side beam 5 is fixedly connected to the support frame 4 8, and the bottom of the side beam 5 is fixedly connected to the support frame 5 9. Then the buoy 3 is fixed. Since the buoy 3 has buoyancy, the device can float.
[0027] The buoy 3 is fixed by fixing the bottom of the side beam 5 to the supporting frame 2 6, the bottom of the side beam 5 to the supporting frame 3 7, the bottom of the side beam 5 to the supporting frame 4 8, and the bottom of the side beam 5 to the supporting frame 5 9. Since the buoyancy of the buoy 3 allows the device to float, compared with the traditional device, this device will not affect the installation, maintenance and use regardless of the amount of leachate collected in the regulating tank. It can not easily clog the pump body according to the amount of leachate, thereby improving the working reliability of the leachate lifting device.
[0028] Among them, sliding grooves 20 are opened on both sides of the sector-shaped hollow block 21, and a sliding block 19 is fixedly installed on the outer surface of the middle part of the clamping block 17, and the sliding block 19 is just located in the sliding groove 20 to slide.
[0029] When the rotating rod 16 drives the locking block 17 to slide in the arc groove 18, it also drives the locking block 17 to slide in the sliding groove 20, which can effectively prevent the locking block 17 from falling off during long-term use.
[0030] The outer side of the connecting pipe 12 is fixedly sleeved with the airtight valve 4 , and the outer side of the airtight valve 4 is fixedly installed with the water outlet pipe 14 .
[0031] The design of the airtight valve 4 can effectively prevent the harmful gases generated during the leachate treatment process from leaking into the surrounding environment, thereby avoiding harm to the workers and the surrounding ecological environment.
[0032] Among them, the bottom of the side beam 5 is fixedly installed with a supporting frame 2 6, a supporting frame 3 7, a supporting frame 4 8, and a supporting frame 5 9, and the shape is an embracing type.
[0033] The design of support frame 2 6, support frame 3 7, support frame 4 8 and support frame 5 9 makes it easy for maintenance personnel to move the equipment to a convenient location for inspection, maintenance and replacement of parts.
[0034] Among them, the grilles 2 are fixedly installed inside the support frame 1 and the intervals between each grille 2 are equidistant.
[0035] The design of the grid 2 can effectively increase the stability of the device and prevent the device from drifting randomly during the floating process.
[0036] Among them, a half-buoy 1 22 is fixedly installed on the middle bottom end of the support frame 2 6, and a half-buoy 2 23 is fixedly installed on the middle bottom end of the support frame 4 8.
[0037] The design of the half buoy 1 22 and the half buoy 2 23 can effectively make maintenance more convenient for maintenance personnel and reduce their workload.
[0038] Among them, the bottom side of the second ring 24 is located at the bottom of the first ring 15 and is fixedly installed with a fan-shaped hollow block 21 and is located between the locking blocks 17.
[0039] The design of the fan-shaped hollow block 21 allows the staff to replace the leachate pipe more quickly, thereby reducing the situation where the device stops operating due to misalignment.
[0040] The working principle and use process of this utility model:
[0041] After the leachate lifting device has been working for a long time, since the leachate raw water contains a variety of pollutants, and these pollutants are very easy to adhere to the surface of the leachate pipe and form scale to cause blockage, when the staff needs to replace the leachate inlet pipe, they rotate the rotating rod 16 at this time. When the rotating rod 16 starts to rotate, it will drive the ring 15 to rotate. When the ring 15 starts to rotate, it will drive the opened arc groove 18 to start rotating. When the arc groove 18 starts to rotate, the opening path of the arc groove 18 is closer and closer to the center, which will tighten the clamping block 17 toward the center. When replacement is needed, it is only necessary to rotate the rotating rod 16 in the opposite direction to quickly replace it.
[0042] Since the entire device is in the regulating tank during long-term operation, it is easy to cause failures and inconvenience in maintenance in the tank. Then the bottom of the side beam 5 is fixedly connected to the support frame 2 6, the bottom of the side beam 5 is fixedly connected to the support frame 3 7, the bottom of the side beam 5 is fixedly connected to the support frame 4 8, and the bottom of the side beam 5 is fixedly connected to the support frame 5 9. Then the buoy 3 is fixed. Since the buoy 3 has buoyancy, the device can float.
