Description

Technical Field

[0001] The utility model belongs to the technical field of landfill leachate treatment, and particularly relates to a landfill leachate separation and treatment device. Background Art

[0002] The treatment of landfill leachate mainly focuses on the treatment operation of high-concentration organic wastewater generated during the landfill or stacking of garbage. The components of landfill leachate are extremely complex, including various pollutants such as high-concentration organic matter, ammonia nitrogen, and heavy metals. If not properly disposed of, it will cause extremely serious harm to the environment, such as polluting the soil, groundwater, etc. Its treatment methods usually cover the comprehensive application of various technical means such as physical treatment, chemical treatment, and biological treatment. Through a series of technological steps such as precipitation, filtration, oxidation, and biodegradation, the pollutants in it are gradually removed to make it meet the discharge standards or meet the requirements for reuse, thereby effectively reducing the adverse impact on the ecological environment.

[0003] For example: The Chinese utility model patent with the publication number "CN215962394U" discloses a landfill leachate treatment device, which includes a landfill leachate treatment tank, and a leachate treatment mechanism is assembled in its inner cavity. During the process of treating garbage, it is necessary to separate the garbage and the leachate in the garbage, and then use the leachate treatment mechanism to achieve this separation operation. In this way, it is convenient for the staff to treat the garbage, effectively improving the efficiency of the staff in separating the garbage and the landfill leachate. Moreover, when using the grid barrel, the garbage can be isolated by the grid barrel, thereby effectively avoiding the situation where the garbage and the leachate are simultaneously thrown out. After the separation of the garbage and the leachate is completed, the grid barrel can be taken out as a whole through the box door, thus reducing the labor intensity of the staff. The above-mentioned landfill leachate treatment device has the advantages of simple structure, convenient operation, and good use effect.

[0004] However, during the actual use of this device, although it can assist in centrifugal filtration, there are still certain defects and deficiencies in its specific application process. First of all, during its use, when the overall filtration is carried out, the filtered impurities will accumulate inside the filter cylinder. When it is necessary to clean these impurities, the filter cylinder often needs to be taken out. However, the filter cylinder is installed inside the device, and obviously this disassembly and cleaning are very inconvenient.

[0037] Compared with the prior art, the above one or more technical solutions in the garbage leachate separation and treatment device provided by the embodiment of the utility model have at least one of the following technical effects:

[0038] When treating garbage, it is necessary to remove the garbage and the leachate in the garbage. Usually, the garbage and the leachate in the garbage are separated by a garbage leachate separation and treatment device, so as to facilitate the staff to treat the garbage.

[0039] When in use, put the garbage into the filter screen cylinder, drive the filter screen cylinder 73 to rotate through the driving assembly 74, so that the garbage in the filter screen cylinder 73 is in a centrifugal state, and the mesh structure of the filter screen cylinder 73 is that the garbage is retained in the filter screen cylinder 73, while the leachate in the garbage is thrown out of the filter screen cylinder 73 and enters the filter box 4, so that the garbage and the leachate are quickly separated, and the separation efficiency is high. While the filter screen cylinder 73 rotates, the stirring mechanism 8 is inserted into the filter screen cylinder 73 to stir the garbage in the filter screen cylinder 73, promote the separation of the leachate and the garbage, and improve the separation efficiency.

[0040] When the fixing screw 11 is tightened, the inner end of each fixing screw 11 passes through a slide groove 5 and presses the outer side of the slide plate 6, thereby fixing the slide plate 6 in the slide groove 5, and then fixing the filter mechanism 7; when it is necessary to clean, maintain or overhaul the filter mechanism 7 and the stirring mechanism 8, by loosening the fixing screw 11, the inner end of the fixing screw 11 releases the pressing of the slide plate 6, and the slide plate 6 can be pulled out of the slide groove 5, thereby removing the filter mechanism 7 and the stirring mechanism 8 from the filter box 4, making it convenient for personnel to clean, maintain or overhaul the filter mechanism 7 and the stirring mechanism 8, and the operation is simple and quick, which can improve the efficiency of the device in disassembly and assembly.

[0041] Among them, refer to Figure 1 and Figure 3 The discharge electromagnetic valve 10 at the bottom of the discharge hopper 9 facilitates the discharge of the leachate in the filter box 4, and the internal electromagnetic valve 75 at the bottom of the filter screen cylinder 73 facilitates the discharge of garbage during cleaning.

[0042] Further, refer to Figure 4, the fixing screw 11 is set as a hand-twist screw. Anti-slip protrusions are fixedly connected to the outer surface of the end knob of the fixing screw 11 at equal intervals. Setting the fixing screw 11 as a hand-twist screw greatly improves the operation convenience. It can be directly tightened or loosened by hand without the aid of tools, making the disassembly and assembly process faster and more convenient. The anti-slip protrusions fixedly connected to the outer surface of the end knob of the fixing screw 11 at equal intervals can increase the friction between the hand and the knob, prevent the hand from slipping during operation, ensure stable force application when tightening or loosening the screw, and improve the operation accuracy and safety.

[0043] In another embodiment of the present utility model, referring to Figure 2 and Figure 3 , the driving assembly 74 includes a side plate 741 and a toothed ring 742; the side plate 741 is fixedly installed at the upper end of a sliding plate 6 and close to one side of the filter mesh cylinder 73. A driving motor 743 is fixedly connected to the top of the side plate 741. The output end of the driving motor 743 penetrates through the side plate 741 and fixedly installs a gear 744. The toothed ring 742 is fixedly installed at the top of the filter mesh cylinder 73 and is coaxially arranged with the filter mesh cylinder 73. The gear 744 and the toothed ring 742 are meshed and connected; during operation, the output end of the driving motor 743 drives the gear 744 to rotate, the gear 744 drives the toothed ring 742 to rotate, thereby driving the filter mesh cylinder 73 to rotate, making the garbage in the filter mesh cylinder 73 in a centrifugal state. The above driving method has a compact structure and high transmission efficiency, and can ensure the stable and continuous rotation of the filter mesh cylinder 73.

[0044] In another embodiment of the present utility model, referring to Figure 2 and Figure 3 , the stirring mechanism 8 includes a plurality of insertion plates 82; a strip-shaped groove 81 is opened on the outer side of each of the plurality of sliding plates 6; each insertion plate 82 is slidably connected in a strip-shaped groove 81. A support frame 83 is fixedly installed at the top of the plurality of insertion plates 82. A stirring assembly 85 is fixedly installed in the middle of the upper end of the support frame 83; the fixing screw 11 is used to tighten or loosen the insertion plate 82 and the sliding plate 6. When the fixing screw 11 is tightened, the inner end of the fixing screw 11 presses against the insertion plate 82, and the insertion plate 82 presses against the sliding plate 6, thereby fastening the insertion plate 82 and the sliding plate 6. When the fixing screw 11 is loosened, the inner end of the fixing screw 11 releases the pressure on the insertion plate 82, and the insertion plate 82 releases the pressure on the sliding plate 6, thereby loosening the insertion plate 82 and the sliding plate 6. The strip-shaped groove 81 opened on the outer side of the sliding plate 6 provides an installation and sliding space for the insertion plate 82. The insertion plate 82 can slide flexibly in the strip-shaped groove 81 to realize the connection or separation of the stirring mechanism 8 and the filtering mechanism 7; when the insertion plate 82 is inserted into the strip-shaped groove 81, the stirring mechanism 8 is inserted into the filter mesh cylinder 73 to stir the garbage in the filter mesh cylinder 73, promote the separation of the leachate from the garbage, improve the separation efficiency, and enable the stirring mechanism 8 and the filtering mechanism 7 to cooperate with each other to jointly complete the treatment work of the garbage leachate.

[0045] Further, referring to Figure 2 and Figure 3 , the stirring assembly 85 includes a stirring motor 855 and a rotating shaft 851; the stirring motor 855 is fixedly installed in the middle of the upper end of the support frame 83, the upper end of the rotating shaft 851 is fixedly connected to the output shaft of the stirring motor 855, a screw conveyor 852 is fixedly installed at the lower end of the rotating shaft 851, the lower end of the screw conveyor 852 is integrally conical in shape, the bottom of the filter screen cylinder 73 is also conical in shape, and the outer side of the screw conveyor 852 is in close connection with the inner wall of the filter screen cylinder 73; the screw conveyor 852 is driven by the stirring motor 855 to rotate, and the rotation direction of the screw conveyor 852 can be the same as or opposite to the rotation direction of the filter screen cylinder 73; when the filter screen cylinder 73 cooperates with the screw conveyor 852 during rotation, it can closely cooperate with the filter screen cylinder 73. On the one hand, it can fully stir the garbage in the filter screen cylinder 73, making the separation effect of garbage and leachate better; on the other hand, this closely fitting structure can better clean the impurities on the inner wall of the filter screen cylinder 73, preventing the impurities from accumulating and blocking the mesh holes of the filter screen cylinder 73. The conical design can also guide the garbage to move downward, which is beneficial to the discharge of the garbage from the inner solenoid valve 75.

[0046] Further, referring to Figure 2 and Figure 3 , a plurality of scraping plates 853 are fixedly installed at equal intervals on the outer surface of the rotating shaft 851. The scraping plates 853 are L-shaped. The outer sides of the plurality of scraping plates 853 are all in close connection with the inner wall of the filter screen cylinder 73. The lower end of the outer surface of the screw conveyor 852 is in close connection with the inner wall of the filter screen cylinder 73. The scraping plates 853 fixedly installed at equal intervals on the outer surface of the rotating shaft 851 are L-shaped and in close connection with the inner wall of the filter screen cylinder 73, which can more comprehensively scrape the inner wall of the filter screen cylinder 73 when the rotating shaft 851 rotates, better cleaning the attached impurities, and further enhancing the cleaning effect on the filter screen cylinder 73. The lower end of the outer surface of the screw conveyor 852 is also in close connection with the inner wall of the filter screen cylinder 73. It can not only promote the separation of garbage and leachate during stirring, but also cooperate with the scraping plates 853, making the stirring and cleaning in the entire filter screen cylinder 73 more meticulous and efficient.

[0047] During use, by opening the discharge solenoid valve 10, the leachate in the filter screen cylinder 73 that is thrown into the filter box 4 flows along the discharge hopper 9 and is discharged from the discharge solenoid valve 10. When the leachate in the garbage is completely separated, the inner solenoid valve 75 is opened, and the inside of the filter screen cylinder 73 is scraped and cleaned by the cooperation of the screw conveyor 852 and the scraping plates 853. The garbage is discharged through the inner solenoid valve 75 and the discharge solenoid valve 10, enabling the device to be disassembled, assembled, and repaired without removing the filtering mechanism 7 and the stirring mechanism 8 when cleaning is required, improving the convenience of use.

[0048] The remaining parts of this embodiment are the same as those of Embodiment 1. For the features not explained in this embodiment, the explanations of Embodiment 1 are adopted and will not be elaborated here.
