[0002] Waste incineration is a process in which waste is reduced in volume through appropriate thermal decomposition, combustion, and melting reactions, resulting in residue or molten fixed substances. By incinerating waste, land can be effectively saved, various pathogens can be eliminated, and harmful and toxic substances can be converted into harmless substances. Therefore, waste incineration has become one of the main methods of urban waste treatment. During the incineration process, leachate in the waste needs to be separated to prevent it from flowing into the grate and corroding the equipment.

[0003] Currently, there are some leachate collection devices for waste incineration power plants on the market, but they generally suffer from the problem of difficult-to-remove filter screens. For example, in the leachate collection device for waste incineration power plants disclosed in patent CN222342145U, the leachate is filtered through a filter screen inside the device.

Therefore, they should not be construed as limitations on this utility model.

[0047] like Figure 1-2 As shown, an embodiment of this utility model provides a leachate collection device for waste incineration power plants, comprising:

[0048] Collection box 1, which has a collection port at its upper end;

[0049] The filter screen 2 is provided on the side wall of the collection box 1, and the filter screen 2 extends into the collection box 1 through the installation port to separate the collection box 1 vertically and is detachably connected to the collection box 1.

[0050] The draining mechanism 3 is disposed on the outside of the collection box 1, and the side wall of the collection box 1 is provided with a discharge port corresponding to the draining mechanism 3;

[0051] A rinsing mechanism 4 is disposed on the outside of the collection box 1, and the side wall of the collection box 1 is provided with a rinsing port corresponding to the rinsing mechanism 4.

[0052] In this embodiment, initially, the drainage mechanism 3 is closed, the filter screen 2 is installed in the installation port and connected to the collection box 1, and the leachate is discharged into the collection box 1 from the collection port. The leachate is then filtered through the filter screen 2, leaving solid foreign objects above the filter screen 2. The leachate passing through the filter screen 2 is collected at the bottom of the collection box 1. When the leachate in the collection box 1 reaches a certain level, the drainage mechanism 3 is opened to discharge the leachate from the collection box 1. Then, the connection between the filter screen 2 and the collection box 1 is disconnected, and the filter screen 2 is pulled out from the installation port. During the pulling process, the portion of the inner wall of the collection box 1 above the installation port scrapes off any remaining solid foreign objects on the filter screen 2, causing them to fall into the collection box 1. The removed filter screen 2 can then be cleaned or replaced. Finally, the flushing mechanism 4 is activated to flush the inside of the collection box 1. The bottom of the collection box 1 is easily flushed, preventing the accumulation of foreign objects and contamination inside the collection box 1.

[0053] Preferably, in another embodiment of the present invention, the upper end of the collection box 1 is open and is provided with a flange 11.

[0054] In this embodiment, by setting flange 11, it is easy to fix collection box 1 at the leachate discharge port of waste incineration equipment.

[0055] Preferably, as another embodiment of this utility model, such as Figure 1-2 As shown, there are two filter screens 2, and the mesh count of the lower filter screen 2 is greater than that of the upper filter screen 2. The collection box 1 is provided with two installation ports.

[0056] In this embodiment, at least two layers of filter screens 2 are provided to achieve multi-stage filtration, which effectively improves the filtration quality of leachate and ensures the cleanliness of the discharged liquid.

[0057] Preferably, as another embodiment of this utility model, such as Figure 3 As shown, the filter 2 includes:

[0058] Filter body 21;

[0059] The filter plate 22 has a notch corresponding to the filter body 21. The filter body 21 is disposed in the notch. The filter plate 22 passes through the mounting port and is slidably connected to the collection box 1.

[0060] A positioning strip 23 is provided at one end of the filter plate 22, and a positioning groove corresponding to the positioning strip 23 is provided on the inner wall of the collection box 1.

[0061] The positioning plate 24 is connected to the filter screen plate 22. When the filter screen 2 is connected to the collection box 1, the filter screen plate 22 is in contact with the inner wall of the collection box 1. The positioning strip 23 is embedded in the positioning groove. The positioning plate 24 abuts against the outer wall of the collection box 1 and is detachably connected to it.

[0062] In this embodiment, after the filter plate 22 is inserted into the installation port, its two sides slide against the inner wall of the collection box 1. Then, the filter plate 22 is pushed inward until the positioning strip 23 is embedded in the positioning groove and the positioning plate 24 abuts against the outer side of the collection box 1. At this time, the collection box 1 can be separated by the filter plate 22. Then, the positioning plate 24 is connected and fixed to the collection box 1. Specifically, a threaded blind hole is provided on the outer wall of the collection box 1, and a positioning hole is provided on the positioning plate 24. When the positioning plate 24 abuts against the collection box 1, the positioning bolt 25 passes through the positioning hole and is threaded into the threaded blind hole. Tightening the positioning bolt 25 can connect and fix the positioning plate 24 to the collection box 1.

[0063] Preferably, as another embodiment of this utility model, such as Figures 2-3 As shown, it also includes:

[0064] Two scrapers 26 are disposed on the inner wall of the collection box 1 and located on the upper and lower sides of the mounting port, respectively. When the filter plate 22 slides in the mounting port, the two scrapers 26 abut against the upper and lower ends of the filter body 21, respectively.

[0065] In this embodiment, by providing two scrapers 26 on the inner wall of the collection box 1, when simply cleaning the filter screen, the filter screen plate 22 can be repeatedly pulled, and solid foreign objects at both ends of the filter screen can be scraped off by the two scrapers 26. This prevents solid foreign objects from entering the installation port and clogging it.

[0066] Preferably, as another embodiment of the present invention, the other end of the filter plate 22 is provided with a handle 27.

[0067] In this embodiment, a handle 27 is provided to facilitate pushing and pulling the filter plate 22 by hand.

[0068] Preferably, as another embodiment of this utility model, Figure 4 As shown, the drainage mechanism 3 includes:

[0069] The liquid discharge tank 31 has an inlet and an outlet at its two ends, and the inlet is connected to the discharge port.

[0070] A baffle 32 is disposed on the drain tank 31 and can open or close the outlet. Specifically, the drain mechanism 3 further includes:

[0071] The threaded rod 33 has a bearing seat embedded in the upper end of the drain tank 31, and the lower end of the threaded rod 33 extends into the bearing seat and is connected thereto.

[0072] The top plate 34 is connected to the upper end of the baffle 32. The upper end of the drain tank 31 is provided with a sliding groove. The lower end of the baffle 32 extends into the sliding groove and slides against the inner wall of the drain tank 31.

[0073] A lifting plate 35 is connected to the top plate 34. The lifting plate 35 passes through the threaded rod 33 and is threadedly connected to it. A nut can be embedded in the lifting plate 35 and is threadedly connected to the threaded rod 33.

[0074] In this embodiment, the movement trajectory of the baffle 32 can be limited by the slide groove, ensuring that it can only slide vertically within the groove. When the threaded rod 33 is rotated, it drives the lifting plate 35 to rotate. However, since the lifting plate 35 is connected to the baffle 32 of the top plate 34, and the baffle 32 can only move vertically, the lifting plate 35 will move up and down relative to the threaded rod 33, thereby driving the baffle 32 to move up and down. When the lower end of the baffle 32 abuts against the bottom wall of the drain tank 31, the outlet of the drain tank 31 is closed. At this time, the top plate 34 abuts against the upper end of the drain tank 31, ensuring a seal between the baffle 32 and the slide groove.

[0075] Preferably, in another embodiment of the present invention, the rinsing mechanism 4 includes:

[0076] Water pump 41;

[0077] Water inlet pipe 42, which is connected to the water inlet of the water pump 41;

[0078] The flushing pipe 43 has its inlet connected to the outlet of the water pump 41. A valve 44 is installed on the flushing pipe 43. The flushing pipe 43 has two outlets connected in series. The collection box 1 is provided with two flushing ports. The two outlets are respectively connected to the two flushing ports.

[0079] In this embodiment, the inlet pipe 42 is connected to an external water source, and the inlet of the water pump 41 is connected to the external water source through the inlet pipe 42. When the water pump 41 is working, it sends the water in the inlet pipe 42 into the flushing pipe 43, and the water is discharged from the flushing port on the collection tank 1 through the two outlets of the flushing pipe 43 to flush the collection tank 1. The flushed water, mixed with solid impurities, enters the drainage mechanism 3. In order to ensure the smooth discharge of solid impurities, the two ends of the drainage tank 31 are opened to form an inlet and an outlet, increasing the area of ​​the inlet and outlet.

[0080] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
