Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a garbage leachate treatment device. Background Art

[0002] The treatment of landfill leachate has always been a very thorny issue in the design, operation and management of landfills. Leachate is the product of the gravity flow of liquid in a landfill. Leachate is a high-concentration organic wastewater with complex components, especially medical waste. If the leachate produced is not treated and directly discharged into the environment, it will cause serious environmental pollution. Therefore, in order to protect the environment, it is necessary to treat the leachate. However, in the existing landfill leachate treatment device, when precipitating and neutralizing the impurities in the leachate, since a part of the impurities in the leachate need to be settled, the treatment chamber needs to be used for a period of time. For example, patents: CN 221344291U and CN 214990665U both use a primary filter box for filtration, and the filter screen in the primary filter box needs to be manually processed, which requires the leachate to be released and the staff to clean the inside of the treatment chamber, which is inefficient and time-consuming and labor-intensive.

[0003] Therefore, it is necessary to provide a new landfill leachate treatment device to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a garbage leachate treatment device.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] See also Figures 1 to 4 The embodiment of the utility model provides a garbage leachate treatment device, which includes a filtrate box 1, a slag drop tube 2 and a material discharge component 4.

[0023] In the embodiments of the present invention, please refer to Figures 1 to 4 The bottom of the filtrate box 1 is a funnel base 11 with a downward conical mouth, and the funnel base 11 is provided with a plurality of evenly distributed filter holes 11a, a filtrate cover 13 is fixedly installed on the funnel base 11, and a liquid storage cavity structure for storing filtrate is formed between the filtrate cover 13 and the funnel base 11, a lower slag pipe 12 is fixedly installed at the bottom of the funnel base 11, and a drain valve 14 is fixedly installed at the bottom of the filtrate cover 13, and a support leg 15 is installed on the filtrate cover 13;

[0024] A slag dropping tube 2 is fixedly installed in the lower slag pipe 12, and the slag dropping tube 2 extends out of the lower slag pipe 12. A slag discharge port 2a is provided on the side tube wall of the slag dropping tube 2 near the bottom, and a sealing tube 3 for sealing the slag discharge port 2a is sleeved on the slag dropping tube 2. Specifically, a threaded section 21 is provided on the outer wall of the slag dropping tube 2 extending out of the lower slag pipe 12, and a threaded ring 31 with a threaded connection is sleeved on the threaded section 21, and the sealing tube 3 is fixedly installed at the bottom of the threaded ring 31.

[0025] It should be noted that: rotating the threaded ring 31 causes the threaded ring 31 to slide down along the threaded section 21, so that the sealing pipe 3 can seal the slag discharge port 2a, and the leachate generated in the landfill is collected and put into the filtrate box 1, and is allowed to stand and be filtered through the filter holes 11a on the filter funnel base 11, and the leachate is processed through a solid-liquid separation device to remove suspended matter and particulate matter, and the filtrate falls into the liquid storage cavity structure and is subsequently discharged by the drain valve 14 to the subsequent processing process equipment for processing.

[0026] In the embodiments of the present invention, please refer to Figures 1 to 4 A material discharge assembly 4 for guiding and discharging slag is installed in the plugging pipe 3, and the material discharge assembly 4 includes a rotating rod 41, and the rotating rod 41 is rotatably installed in the slag dropping barrel 2, and a spiral plate 43 is fixedly sleeved on the rotating rod 41, and the spiral plate 43 is located in the slag dropping barrel 2, and the spiral plate 43 is rotatably connected to the inner wall of the slag dropping barrel 2, and a servo motor 42 for driving the rotating rod 41 to rotate is fixedly installed at the bottom of the slag dropping barrel 2;

The cleaning plates 5 are provided in plurality and are fixedly mounted on a rotating rod 41 extending into the funnel base 11. The cleaning plates 5 are distributed in a ring on the rotating rod 41 and are against the inner wall of the funnel base 11.

[0028] It should be noted that: when the leachate is filtered, the threaded ring 31 is rotated so that the threaded ring 31 slides up along the threaded section 21, so that the sealing tube 3 is rotated away from the slag discharge port 2a. Since the bottom of the filtrate box 1 is provided with a funnel base 11 with a downward conical mouth, the filter residue in part of the leachate can fall into the slag discharge tube 2 along the inclined bucket surface, so that after the servo motor 42 is turned on to drive the spiral plate 43 to rotate, the filter residue can be transported downward along the spiral plate 43 and discharged from the slag discharge port 2a. At the same time, the cleaning plate 5, driven by the rotating rod 41, cleans the filter residue attached to the funnel base 11, so that it falls into the slag discharge tube 2 and is spirally discharged. During the whole process, there is no need to manually clean the filter hole 11a, and the filter residue can be quickly processed, and the operation is simple.

[0029] The working principle of the garbage leachate treatment device provided by the utility model is as follows:

When the leachate is filtered, the threaded ring 31 is rotated to make the threaded ring 31 slide up along the threaded section 21, so the plugging pipe 3 is Rotate away from the slag discharge port 2a. Since a funnel base 11 with a downward conical mouth is provided at the bottom of the filtrate box 1, the filter residue in part of the garbage leachate can fall into the slag discharge tube 2 along the inclined bucket surface, so that after the servo motor 42 is turned on to drive the spiral plate 43 to rotate, the filter residue can be transported downward along the spiral plate 43 and discharged from the slag discharge port 2a. At the same time, the cleaning plate 5, driven by the rotating rod 41, cleans the filter residue attached to the funnel base 11, so that it falls into the slag discharge tube 2 and is spirally discharged. During the whole process, there is no need to manually clean the filter hole 11a, and the filter residue can be quickly processed, and the operation is simple.
