[0002] Leachate refers to a high-concentration organic wastewater formed by the moisture contained in the garbage itself in the landfill, rainwater, snow and other moisture entering the landfill, minus the saturated water holding capacity of the garbage and covering soil layers, and passing through the garbage layer and covering soil layers. There is also moisture leaked from the accumulated garbage prepared for incineration. The treatment of leachate is also a type of garbage disposal.

[0003] At present, various water treatment processes are used to treat leachate in the garbage disposal process. However, the dripping leachate cannot be pretreated during the garbage transportation process, and a large amount of consumables are required for the subsequent treatment of the leachate. Therefore, a garbage leachate pretreatment device is proposed. When the garbage moves on the guide slide, the dripping leachate falls into the treatment box through the through hole, and the dosing component draws the water treatment agent in the medicine box into the treatment box. The stirring component mixes the water treatment agent and the garbage leachate to pretreat them, thereby reducing the amount of consumables invested in the subsequent treatment of the garbage leachate, saving energy and being environmentally friendly.

A drive motor 603 is installed on one side surface of the processing box 1 through a mounting frame.

[0024] During use, when the garbage moves in the guide chute 2, the wastewater drips into the treatment box 1 through the through hole 9, the water pump 701 pumps the water treatment agent in the medicine box 4 into the treatment box 1, and the drive motor 603 drives the cross bar 601 and the stirring rod 602 on its outside to mix the wastewater and water treatment agent in the treatment box 1.

[0025] For example, Figure 2 、 Figure 3 As shown, the utility model also includes limiting slide grooves 10 at both ends of the inner side of the material guide slide 2, a material blocking assembly 3 is provided on the top of the material guide slide 2, and the material blocking assembly 3 includes a gantry 301 fixed to the top of the material guide slide 2 by bolts, and a cylinder 302 is installed on the top of the gantry 301 through a mounting frame.

[0026] When in use, the cylinder 302 is used to push the connecting rod 303 and the baffle 304 at the bottom thereof to move up and down.

[0027] For example, Figure 2 、 Figure 3 As shown, the utility model also includes that the output shaft of the cylinder 302 located inside the gantry 301 is connected to the connecting rod 303 through a connecting sleeve, and the bottom end of the connecting rod 303 is fixed with a baffle 304 through a flange, and both sides of the baffle 304 are located inside the limiting slide groove 10.

[0036] External lifting equipment and the like lift the garbage onto the guide chute 2. Due to the inclination angle of the bottom of the guide chute 2, the garbage slides downward on the guide chute 2. During the movement of the garbage, the sewage inside it falls into the treatment box 1 or into the guide hopper 5 through multiple through holes 9. After being guided by the guide hopper 5, it falls into the treatment box 1 again. The filter plate 8 can fix the garbage to prevent small particles from clogging the through holes 9. The garbage is transported by the inclination angle of the guide chute 2 and the weight of the garbage itself, which is energy-saving and environmentally friendly.

[0037] Open the cylinder 302 and push the baffle 304 downward through the connecting rod 303, so that the baffle 304 is inserted into the material guide chute 2, which can block the garbage in the material guide chute 2 and allow the waste water inside to drip fully. When the baffle 304 moves up and down, its two sides slide in the limiting chute 10, which can prevent the baffle 304 from tilting;

[0038] Turn on the water pump 701 to extract the water treatment agent in the medicine box 4 through the water inlet pipe 702, and transport it to the guide hopper 5 through the water outlet pipe 703.
