[0022] This part will describe the specific embodiments of the present application in detail, and the preferred embodiments of the present application are shown in the drawings, and the drawings are used to supplement the description of the text part in the form of graphics, so that people can intuitively and visually understand each technical feature and the overall technical scheme of the present application, but it cannot be understood as a limitation on the protection scope of the present application.

[0023] Please refer to Figures 1-3The utility model provides a technical scheme: a kind of landfill leachate pretreatment machine, including cabinet 1, the inside bottom side of cabinet 1 is fixedly installed with filter plate 2. Filter plate 2 carries out filtration to landfill leachate.

[0024] The inside left and right of cabinet 1 is movably provided with moving pipe 3. The outer side of moving pipe 3 is uniformly fixed with multiple spray heads 4. Multiple spray heads 4 are evenly distributed along the axis of moving pipe 3, so that the flocculation reagent is sprayed more evenly.

[0025] Specifically, the inner wall of cabinet 1 is provided with a limiting groove 8 on both sides, and a limiting block 9 is fixedly installed at both ends of the moving pipe 3, and the limiting block 9 is slidingly installed in the limiting groove 8. A reciprocating screw 10 is rotatably installed in the inside of the cabinet 1. A motor 12 is fixedly installed on the side wall of the cabinet 1, and the output shaft of the motor 12 is fixedly connected with one end of the reciprocating screw 10. A connecting block 11 is fixedly connected with the bottom side of the moving pipe 3, a ball nut is embeddedly installed on the connecting block 11, and the ball nut is connected with the reciprocating screw 10. The output shaft of the motor 12 drives the reciprocating screw 10 to rotate, the reciprocating screw 10 drives the connecting block 11 to reciprocate left and right outside the reciprocating screw 10, and then the mixed landfill leachate is accelerated.
