[0032] The utility model is further described in conjunction with the following embodiments.

[0033] Example 1.

[0034] like Figure 1-2 As shown, a device for collecting and treating leachate from hazardous waste incineration and landfill includes a treatment box 1, a feed port 2 is opened on the top of the box, the bottom end of the feed port 2 is fixedly connected to a first extrusion component 3, the top of the first extrusion component 3 is fixedly connected to a fixing rod 4, the top of the fixing rod 4 is fixedly connected to the inner wall of the treatment box 1, the first extrusion component 3 is connected to a second extrusion component 5, the second extrusion component 5 is connected to a discharge port 6, a stirring mechanism 7 is connected below the first extrusion component 3 and the second extrusion component 5, and electric valves 10 are installed on the feed port 2 and the discharge port 6.

[0035] The hazardous waste enters the first extrusion component 3 from the feed port 2 for the first extrusion, and the extruded leachate enters the stirring mechanism 7. Then the hazardous waste enters the second extrusion component 5 for the second extrusion, and the leachate extruded for the second time also enters the stirring mechanism 7. After two extrusions, the hazardous waste is discharged from the discharge port 6.

[0036] The first extrusion assembly 3 includes a first extrusion chamber 31, the top of the first extrusion chamber 31 is fixedly connected to the fixing rod 4, the first extrusion chamber 31 is connected to the feed port 2, the side of the first extrusion chamber 31 is fixedly installed with a first motor 31, the output shaft of the first motor 31 is connected to a screw push rod 33, the screw push rod 33 is rotatably connected to a fixing sleeve 34, and a first filter layer 35 is provided on the lower side of the first extrusion chamber 31, and the outer side of the first filter layer 35 is fixedly connected to the first guide channel 36.

[0037] The hazardous waste enters the first extrusion chamber 31, and the first motor 31 drives the screw push rod 33 to rotate, pushing the hazardous waste to the second extrusion assembly 5. Since the first extrusion chamber 31 is conical, the blade diameter of the screw push rod 33 gradually becomes smaller, and the gap between the blades gradually decreases, so that the liquid in the garbage is squeezed for the first time. The squeezed leachate flows downward through the inner wall of the chamber, passes through the first filter layer 35 and the first guide channel 36, and enters the stirring mechanism 7.

[0038] The second extrusion assembly 5 includes a second extrusion chamber 51, a second filter layer 52 is arranged on the lower side of the second extrusion chamber 51, the outer side of the second filter layer 52 is connected to the second guide channel 53, the bottom end of the second guide channel 53 is connected to the stirring mechanism 7, and a second motor 54 is installed on the upper part of the outside of the second extrusion chamber 51, and the second motor 54 is transmission-connected to two transmission shafts 55, each transmission shaft 55 is rotationally connected to a fixed seat, each transmission shaft 55 is threadedly connected to a U-shaped frame 56, and the bottom end of each U-shaped frame 56 is fixedly connected to an extrusion plate 57.

[0040] After the first extrusion, the hazardous waste enters the second extrusion chamber 51. The second motor 54 drives the two transmission shafts 55 to rotate towards each other, so that the two U-shaped frames 56 move towards each other, thereby driving the two extrusion plates 57 to perform extrusion and separation operations. The leachate generated by the secondary extrusion passes through the second filter layer 52 and the second guide channel 53 and enters the stirring mechanism 7.

[0041] The stirring mechanism 7 includes a stirring box 71 and a dosing pump 72. A stirring motor 73 is installed on the top of the stirring box 71. A driving gear 74 is installed at the bottom of the output shaft of the stirring motor 73. The driving gear 74 is connected to the transmission belt 75.

[0043] At the same time, a water outlet 8 is opened on the lower side of the stirring box 71, and the water outlet 8 is provided with an impurity filter 9 for filtering the leachate after the drug reaction. The water outlet 8 is installed with an electric valve 10, which is a prior art and will not be described in detail.

[0044] The utility model installs the first extrusion component 3. As the diameter of the first extrusion chamber 31 and the diameter of the blades of the spiral push rod 33 gradually decrease, the blade spacing gradually decreases, thereby realizing the initial extrusion of hazardous waste. By installing the second extrusion component 5, the second motor 54 controls the movement of the extrusion plate 57 to perform secondary extrusion on the hazardous waste. The leachate generated by the last two extrusions enters the stirring box 71, and the stirring motor 73 cooperates with the dosing pump 72 to perform drug treatment on the leachate, thereby avoiding the pollution of the surrounding environment by a large amount of leachate contained inside the landfill during landfill, and at the same time, the leachate is preliminarily treated.
