Description

Technical Field

[0001] The present application relates to the technical field of garbage disposal devices, and in particular to a garbage leachate dredging device. Background Art

[0002] Currently, most urban waste is sorted at waste treatment stations and then transported to waste-to-energy plants for incineration and power generation, achieving both harmlessness and resource utilization. Urban waste typically contains a high moisture content. To reduce this moisture content before incineration, improve incineration efficiency, and ensure waste disposal quality, my country's waste-to-energy design specifications require that waste be stored in a waste pit for seven days prior to incineration. This reduces moisture content and increases the calorific value of the waste entering the incinerator.

[0003] In my country's existing waste incineration power plants, the garbage storage pools basically use flat-bottomed deep pits with infiltration ditches to collect leachate, but the holes in the leachate grille are easily clogged, and the infiltration effect is very unsatisfactory. Some waste incineration power plants have begun to use a garbage pool leachate grille system with a dredging function. The use of new equipment can improve the efficiency of garbage disposal. However, since the garbage pool leachate system is composed of multiple windows, the window width is generally only 600mm, and the dredging equipment is about 500mm wide. The conventional design method connects the dredging equipment to the leachate grille through a guide column, and the slide slides back and forth on the guide column. The guide column plays a guiding role and provides weight support for the slide. The strength and installation accuracy of the guide column are very high. At the same time, the processing accuracy of the leachate grille is also very high. In addition, the leachate window is small, and the garbage pool leachate grille system needs to assemble multiple parts during installation, which makes it inconvenient to implement mechanized installation, resulting in low equipment installation efficiency on site. Utility Model Content

[0009] The prefabricated frame can be directly fixed on the wall, and the dredging component includes a sliding plate slidably installed on the prefabricated frame and a plurality of dredging columns fixedly installed on the sliding plate for dredging the leachate grid plate. The plurality of dredging columns are arranged at intervals on the sliding plate.

[0010] Preferably, the prefabricated frame includes a sliding plate and a guide column, one side of the guide column is connected to the sliding plate, and the other side is connected to the leachate grid plate, the sliding plate is located between the sliding plate and the leachate grid plate, and the sliding plate is sleeved and slid on the guide column.

The slide support plate is provided with a through opening for the dredging column to pass through.

[0012] Preferably, one penetration opening is provided, and a plurality of dredging columns pass through the same penetration opening.

[0013] Preferably, a positioning groove for inserting the dredging column is provided on the sliding plate.

[0019] The ram support plate is located between the leachate grid plate and the ram plate, so that the ram plate is not easily in direct contact with the leachate grid plate during the sliding process, thereby preventing the ram or the leachate grid plate from being damaged due to collision;

[0020] The setting of the elastic ring allows the garbage leachate on the surface of the dredging column to be wiped off during the return journey, thereby preventing the dredging column from bringing the garbage leachate attached to its surface into the prefabricated frame and corroding it during the return journey.

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] The embodiment of the present application discloses a garbage leachate dredging device.

[0028] Reference Figure 1 The garbage leachate dredging device includes a dredging module 1 and a power drive component 2. The dredging module 1 is assembled before leaving the factory. On site, you only need to install the power drive component 2 on the dredging module 1, and then install the dredging module 1 on the leachate grid plate. The above structure modularizes multiple components, making it more convenient to install on site and more efficient in installation and debugging.

[0029] Reference Figure 1 The dredging module 1 includes a prefabricated frame 11 and a dredging assembly 12. One side of the prefabricated frame 11 is mounted on the wall, and the other side is connected to the leachate grid. The dredging assembly 12 is slidably mounted on the prefabricated frame 11 to dredge the leachate grid. The power drive 2 is mounted on the prefabricated frame 11 to drive the dredging assembly 12 to slide back and forth to dredge the leachate grid.

[0030] Reference Figure 1 and Figure 2 The prefabricated frame 11 includes a ram fixing plate 13, guide posts 14, and a ram support plate 15. Both the ram fixing plate 13 and the ram support plate 15 are sleeved onto the guide posts 14, and are spaced apart along the extension direction of the guide posts 14. The dredging assembly 12 slides between the ram fixing plate 13 and the ram support plate 15. The ram fixing plate 13 can be fixed to the wall at the corresponding position using connectors.

[0031] In this embodiment, both the ram fixing plate 13 and the ram support plate 15 are preferably rectangular plates. Four guide posts 14 are provided, all structurally identical, and are located at four right angles to the ram fixing plate 13. Positioning holes are defined at each of the four right angles of the ram fixing plate 13, and the four guide posts 14 are inserted into corresponding positioning holes, thereby ensuring precise installation between the guide posts 14 and the ram fixing plate 13. The end of the guide post 14 closest to the ram fixing plate 13 is inserted into the positioning hole and then welded to the ram fixing plate 13.

[0032] Reference Figure 1 and Figure 2 Similarly, holes are provided at the four right angles of the ram support plate 15 for the corresponding guide posts 14 to pass through. The end of the guide post 14 facing away from the ram fixing plate 13 passes through the holes and protrudes from the ram support plate 15. The ram support plate 15 is also welded to the guide post 14. The protruding portion of the guide post 14 facing away from the ram fixing plate 13 will abut against the leachate grating plate, so that the leachate grating plate and the ram support plate 15 are arranged at intervals. This makes it difficult for the dredging assembly 12 to directly collide with the leachate grating plate and cause damage to the leachate grating plate during the sliding dredging process. Bolt holes are provided on the ram support plate 15, and the ram support plate 15 is fixed to the leachate grating plate by bolts and nuts. In another embodiment, the end of the guide post 14 close to the leachate grating plate is directly fixed to the leachate grating plate.

[0033] Reference Figure 1 and Figure 2 The dredging assembly 12 includes a ram plate 16 and dredging posts 17. The ram plate 16 is also a rectangular plate. Four guide posts 14 pass through the four right angles of the ram plate 16. The ram plate 16 is located between the ram fixing plate 13 and the ram support plate 15, and the ram plate 16 slides on the four guide posts 14. Multiple dredging posts 17 are provided, and each of the multiple dredging posts 17 is located on the side of the ram plate 16 near the ram support plate 15. The multiple dredging posts 17 are arranged at intervals on the ram plate 16 and move synchronously with the ram plate 16. The multiple dredging posts 17 can be inserted into corresponding holes on the leachate grid plate to achieve a dredging effect.

[0034] Reference Figure 2 and Figure 3 The structures and installation arrangements of the multiple dredging columns 17 are identical. The following describes the structure and installation arrangements of one dredging column 17 as an example. A positioning groove 161 is provided on the side of the ram plate 16 near the ram support plate 15 for inserting the dredging column 17. The number of positioning grooves 161 matches the number of dredging columns 17 and corresponds one-to-one. A positioning ring 171 is sleeved on the outer peripheral wall of the dredging column 17 near the ram plate 16. The positioning ring 171 is welded to the guide column 14. After the dredging column 17 is inserted into the positioning groove 161, the positioning ring 171 abuts against the ram plate 16, and the positioning ring 171 is welded to the ram plate 16. On the one hand, the provision of the positioning groove 161 enables the guide column 14 to be positioned and installed, thereby ensuring the alignment of the guide column 14 with the holes in the leachate grid plate. On the other hand, the provision of the positioning ring 171 increases the contact area between the guide column 14 and the ram plate 16, making the guide column 14 more stable after being welded to the ram plate 16.

[0035] In order to prevent the sliding support plate 15 from interfering with the dredging column 17 when the dredging column 17 dredges the leachate grid plate, a penetration opening 151 is provided on the support plate for the dredging column 17 to pass through. In this embodiment, one penetration opening 151 is preferably provided, and multiple dredging columns 17 all pass through the same penetration opening 151.

[0036] Reference Figure 3 and Figure 4 In this embodiment, the power drive element 2 is preferably a hydraulic cylinder. The cylinder body of the hydraulic cylinder is bolted to the side of the ram fixing plate 13 facing away from the ram support plate 15. The telescopic rod of the hydraulic cylinder passes through the ram fixing plate 13 and is connected to the ram plate 16. Specifically, a connecting seat 18 is fixedly mounted on the side of the ram plate 16 near the ram fixing plate 13. A connecting lug 181 is welded to the side of the connecting seat 18 near the ram fixing plate 13. The telescopic rod of the hydraulic cylinder is connected to the connecting lug 181 via a pin. Therefore, when clearing the leachate grid plate, the power drive element 2 can drive the multiple clearing posts 17 to move synchronously to achieve a clearing effect.

[0037] The implementation principle of a garbage leachate dredging device according to an embodiment of the present application is as follows: first, the structure of the dredging device is set as a modular structure, and the prefabricated frame 11 and the dredging component 12 are assembled before leaving the factory to form an integral module. At the construction site, it is only necessary to install the power drive component 2 on the slide fixing plate 13 and connect the power drive component 2 to the slide plate 16 to drive the slide plate 16 to move, and then fix the slide fixing plate 13 on the wall at the corresponding position, and then fix the slide support plate 15 on the leachate grille plate to realize the installation, and finally debug the device, thereby improving the installation and debugging efficiency on site.

[0038] Secondly, the dredging column 17 can be positioned and installed on the slide fixing plate 13 through the positioning groove 161, so that the dredging column 17 and the corresponding holes of the leachate grid plate are highly aligned, thereby making the dredging column 17 more accurate during dredging.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
