Description

Technical Field

[0001] This utility model relates to the field of waste settling technology, specifically a landfill settling device. Background Technology

[0002] Landfill settlement refers to the phenomenon where, over time, the surface of the landfill area gradually shifts downwards after waste is placed in a landfill. This process involves the reduction in volume and structural changes of landfill waste under various physical, chemical, and biological influences, leading to a decrease in the surface height of the landfill.

[0003] Landfill settling requires sampling and testing equipment, but it is inconvenient for staff to carry samplers to take samples in settling ponds, making the operation inconvenient and hindering the understanding of the waste settling treatment situation. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a landfill settling device.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a landfill settling device, comprising a settling box, a sampling device, and an adjustment assembly. The settling box is provided with a settling trough with an upper opening. The adjustment assembly includes a cover, a motor, a worm gear, a worm, a screw, and a support. The cover and the support are symmetrically arranged at both ends above the settling box. The cover also contains a worm and two sets of worm gears, with the worm meshing with the two sets of worm gears. The output end of the motor passes through the cover and is connected to the worm. The screw is arranged in two symmetrical sets, with one end of the screw rotatably connected to the support and the other end passing through the cover and connected to the center of the worm gear. The sampling device includes a sliding plate, a lifting device, a lifting plate, and a sampler. The left and right sides of the sliding plate are provided with threaded holes for threaded connection with the screw. The lifting device passes through the sliding plate and is connected to the lifting plate. A sampler is also provided below the lifting plate.

[0008] To facilitate the disassembly and assembly of the sampling cylinder, this utility model is improved by including a stud and a sampling cylinder in the sampler, and a number of studs are also provided below the lifting plate. The upper part of the sampling cylinder is threadedly connected to the stud, and a sampling groove is provided below the sampling cylinder.

[0009] Preferably, the motor is a servo motor.

[0010] Preferably, the lifting device is a hydraulic cylinder.

[0011] To ensure the stability of the lifting process, this invention is improved by providing a guide rod that passes through the sliding plate on the lifting plate.

[0012] Preferably, the guide rods are arranged in two symmetrical sets.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a landfill settling device, which has the following beneficial effects:

[0015] This landfill settling device, when sampling is required at different locations or depths within the settling tank, activates the motor. The motor drives the worm gear to rotate precisely, which in turn drives the worm wheel, causing the screw to rotate synchronously. The slide plate adjusts its horizontal position, and the lifting device (using a hydraulic cylinder to provide stable and large linear thrust) passes through the slide plate and connects to the lifting plate. When sampling is needed, the hydraulic cylinder is activated, its piston rod extends, and pushes the lifting plate downwards smoothly, driving the sampler to insert into the waste, thus achieving the sampling action. Because the hydraulic cylinder can provide a large thrust, even when facing certain resistance from landfill waste (such as high compaction), it ensures that the sampler can be inserted smoothly, guaranteeing successful sampling.

[0021] 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.

[0022] Please refer to Figures 1-4. A landfill settling device includes a settling tank 1, a sampling device, and an adjustment assembly. The settling tank 1 is provided with a settling trough with an upper opening. The adjustment assembly includes a cover 2, a motor 3, a worm gear 4, a worm 5, a screw 6, and a support 7. The cover 2 and the support 7 are symmetrically arranged at both ends above the settling tank 1. The worm 5 and two sets of worm gears 4 are also provided inside the cover 2. The worm 5 meshes with the two sets of worm gears 4. The output end of the motor 3 passes through the cover 2 and is connected to the worm 5. The screw 6 is arranged in two symmetrical sets. One end of the screw 6 is rotatably connected to the support 7, and the other end of the screw 6 passes through the cover 2 and is centrally connected to the worm gears 4. The sampling device includes a sliding plate 8, a lifting device 9, a lifting plate 10, and a sampler 11. The sliding plate 8 has screw holes on its left and right sides that are threaded to the screw 6. The lifting device 9... The slide plate 8 passes through and is connected to the lifting plate 10. A sampler 11 is also provided below the lifting plate 10.

[0023] The settling tank 1 is equipped with a settling trough with an upper opening. After the garbage is filled into the settling trough through the upper opening, it undergoes volume changes and structural alterations under multiple physical, chemical, and biological effects, resulting in settling. The cover 2 is equipped with a meshing worm 5 and two sets of worm wheels 4. The output end of the motor 3 (using a servo motor 3, which can precisely control the rotation) passes through the cover 2 and is connected to the worm 5. Two sets of symmetrically arranged screws 6 are rotatably connected at one end to the bracket 7, and the other end passes through the cover 2 and is respectively connected to the center of the corresponding worm wheel 4. The sliding plate 8 of the sampling device has screw holes on both sides that are threaded to the screws 6. When it is necessary to adjust the horizontal position of the sampling device, the motor 3 is started. The motor 3 drives the worm 5 to rotate. According to the transmission principle of worm wheel 4 and worm 5, the rotation of the worm 5 will drive the two sets of worm wheels 4 meshing with it to rotate synchronously, thereby causing the screws 6 to rotate accordingly. Based on the principle of threaded transmission, the sliding plate 8, which is threadedly connected to the screw 6, moves linearly along the screw 6, thereby driving the entire sampling device to move horizontally above the settling tank 1. Thanks to the use of a servo motor 3, the operator can precisely control the rotation angle, rotation speed, and other parameters of the motor 3, thus accurately adjusting the horizontal position of the sampling device. This allows it to move precisely above the predetermined sampling position within the settling tank 1, solving the problem of traditional settling tanks having difficulty flexibly changing the sampling position. This facilitates targeted sampling of waste settling conditions in different areas. The sliding plate 8, as the component connecting the sampling device and the adjustment assembly, is threadedly connected to the screw 6 through screw holes on both sides, achieving a stable fit with the adjustment assembly and accurately adjusting its position as the adjustment assembly moves.

[0024] The lifting device 9 (which uses a hydraulic cylinder to provide stable and large linear thrust) passes through the slide plate 8 and is connected to the lifting plate 10. When sampling is required, the hydraulic cylinder is activated, the piston rod of the hydraulic cylinder extends, and pushes the lifting plate 10 to move downward in a straight line along the guide rod 14 (the guide rod 14 is set in two symmetrical arrangements, which pass through the slide plate 8, ensuring that the lifting plate 10 can only make stable vertical movements during the lifting process, avoiding tilting, swaying and other situations).

[0025] The sampler 11, located below the lifting plate 10, descends along with the lifting plate 10. The sampler 11 consists of a stud 12 and a sampling cylinder 13. The sampling cylinder 13 is connected to the stud 12 via threads, facilitating disassembly and assembly for subsequent sample removal, cleaning, and replacement. During the insertion of the sampling cylinder 13 into the waste, the sampling groove below it collects the waste. Once the sampling cylinder 13 is fully inserted into the waste at the predetermined depth, the waste sample remains in the sampling groove. Subsequently, the piston rod is retracted by controlling the hydraulic cylinder, causing the lifting plate 10 and sampler 11 to rise, completing one sampling operation. The obtained waste sample can be used to analyze changes in waste composition and sedimentation levels, thereby helping staff understand the waste sedimentation treatment process.
