Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, specifically to a device for treating urban waste leachate. Background Technology

[0002] With the acceleration of urbanization and the high concentration of urban population, the amount of urban waste generated has exploded. Currently, landfill remains one of the main methods of urban waste disposal. During the landfill process, moisture and precipitation in the waste gradually seep in and react with various components of the waste, producing a large amount of leachate. This is where leachate treatment equipment becomes necessary.

[0003] There are many types of urban landfill leachate treatment devices with different functions, mainly including pretreatment, biological treatment, advanced treatment, and sludge treatment devices. Each link works closely together to purify the landfill leachate and ensure that it meets discharge standards. The pretreatment device mainly includes a screen, which is composed of a set of parallel metal bars or screens. It is mainly used to intercept larger suspended and floating objects in the landfill leachate, such as plastic bags, branches, and fibers. If these debris are not removed in time, they will block the pipes and orifices of subsequent treatment equipment, affecting the treatment effect. However, the screen needs to be cleaned regularly during use. The existing cleaning method requires manual removal of the screen from the device and then cleaning it. This is not only inefficient but also wastes manpower and reduces the pretreatment efficiency of urban landfill leachate. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model discloses a municipal solid waste leachate treatment device, comprising a treatment tank 1, a drain pipe at the lower end of the treatment tank 1, a base frame 10 inside the treatment tank 1, grid bars on the base frame 10, a top frame 5 above the base frame 10, a vertical rod 11 penetrating the top frame 5 at the upper end of the base frame 10, a positioning seat 12 in the middle part of the top frame 5, a threaded rod 13 penetrating the positioning seat 12 in the middle part of the base frame 10, the threaded rod 13 being slidably connected to the positioning seat 12, and an annular block 14 rotatably disposed on the positioning seat 12 through which the threaded rod 13 is penetrating, the annular block 14 being threadedly connected to the threaded rod 13, the outer ring of the annular block 14 being provided with a toothed ring, and a second motor 15 above the positioning seat 12, the output end of the second motor 15 being provided with a gear 16 meshing with the toothed ring;

[0026] The top of the processing box 1 is provided with a fixing frame 9 fixed to one side of the processing box 1. A first motor 7 is provided on the outside of the fixing frame 9. The output end of the first motor 7 is provided with a rotating shaft 8. A side block 6 is provided on one side of the top frame 5 through which the rotating shaft 8 passes, and the side block 6 is fixedly connected to the rotating shaft 8.

[0027] The operation of urban landfill leachate treatment facilities mainly covers two key stages: landfill leachate treatment and grid cleaning.

[0028] Leachate treatment stage: Municipal waste leachate is injected into the treatment tank 1 from the top. The base frame 10 inside the treatment tank 1 is equipped with grid bars. When the leachate flows through the grid bars, larger suspended and floating objects such as plastic bags, branches, and fibers are effectively intercepted, thus completing the initial filtration of the leachate. After initial treatment, the leachate is discharged systematically to a designated location through the drain pipe at the bottom of the treatment tank 1 for subsequent treatment processes.

[0029] In this embodiment, the upper end of the positioning seat 12 is provided with an annular groove 18, and the lower end of the annular block 14 is provided with an annular protrusion that is inserted into the annular groove 18 and rotatably connected to the annular groove 18. The annular protrusion matches the annular groove 18, which can ensure the stability of the annular block 14 when rotating.

[0030] In this embodiment, the plurality of vertical rods 11 are respectively installed at the four corners of the base frame 10.

[0031] Bar cleaning stage: When cleaning the bars, the second motor 15 above the positioning seat 12 is started first. The output end of the second motor 15 drives the gear 16 to rotate. Since the gear 16 is tightly meshed with the toothed ring on the outer ring of the annular block 14, the rotation of the gear 16 will drive the annular block 14 to rotate together. The annular block 14 and the threaded rod 13 that passes through the positioning seat 12 are connected by threads, and the threaded rod 13 and the positioning seat 12 are slidably connected. Under the action of this threaded transmission structure, the rotation of the annular block 14 will cause the threaded rod 13 to move relative to the positioning seat 12, thereby driving the base frame 10 to slowly rise along the vertical rod 11 until the base frame 10 is raised above the processing box 1. It is worth mentioning that vertical rods 11 are installed at all four corners of the base frame 10. These vertical rods 11 play an important role in the lifting and lowering process of the base frame 10, greatly improving the stability of the base frame 10 during lifting and lowering.

[0032] After the base frame 10 is successfully raised above the processing box 1, the first motor 7 on the outside of the fixed frame 9 is then started. The output end of the first motor 7 drives the rotating shaft 8 to rotate. Since the side block 6 on one side of the top frame 5 is penetrated by the rotating shaft 8 and fixedly connected to the rotating shaft 8, the rotation of the rotating shaft 8 will cause the side block 6 to drive the top frame 5 and the base frame 10 connected to the top frame 5 through the vertical rod 11 to rotate 180 degrees synchronously.

[0033] In this embodiment, the bottom of the processing box 1 is provided with a carrier box 2 located on one side of the processing box 1. The carrier box 2 is provided with a drawer slot 3, and a storage box 4 is pulled out and installed in the drawer slot 3.

[0034] After the base frame 10 rotates 180 degrees, the debris attached to the grid bars will fall off by tapping the base frame 10. The bottom of the processing box 1 is equipped with a carrying box 2, which is equipped with a drawer slot 3. A pull-out storage box 4 is installed in the drawer slot 3. The fallen debris will fall directly into the storage box 4, thereby realizing the centralized collection and convenient disposal of debris.

[0035] This device utilizes an innovative motor-driven design to achieve automatic lifting and rotation of the base frame 10. This design overcomes the limitations of traditional manual cleaning, eliminating the need for manual removal of the grilles from the device. The grille cleaning can be easily completed through simple motor operation and tapping, significantly improving cleaning efficiency.

[0036] Reducing manual operations significantly alleviates the workload of operators and effectively lowers labor costs. Operators only need to perform simple operations such as starting the motor to complete complex bar cleaning tasks, making the workflow more convenient and efficient.

[0037] Timely cleaning of the grid bars ensures that they maintain good interception performance, effectively preventing debris from clogging the bars and affecting the pretreatment efficiency of landfill leachate, thus providing a strong guarantee for the stable and efficient operation of the entire city's landfill leachate treatment system.

[0038] In this embodiment, the second motor 15 is fixed above the positioning seat 12 by a support rod.

[0039] In this embodiment, the top of the processing box 1 is provided with a support frame 17 for supporting the top frame 5.

[0040] The second motor 15 is securely fixed above the positioning seat 12 by a support rod. This design not only facilitates the assembly of the motor, but also further optimizes the overall structure of the device, making the device more stable and reliable, and effectively extending its service life.

[0041] In this embodiment, both the first motor 7 and the second motor 15 are servo motors.

[0042] Both the first motor 7 and the second motor 15 are servo motors, which have precise speed and position control capabilities. This feature enables the base frame 10 to perform key actions such as lifting and rotating with precision, greatly improving the working accuracy and operational reliability of the device and ensuring stable operation under various working conditions.
