Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to an integrated treatment device for landfill leachate. Background Technology

[0002] In integrated landfill leachate treatment equipment, the application of a compression device is crucial during the pretreatment of landfill waste. However, existing landfill compression devices often have many shortcomings. Currently common compression equipment often fails to fully compress the waste during the process of squeezing out the water, leaving a large amount of water residue in the waste. This results in low filtrate discharge efficiency and makes it difficult to effectively achieve waste dehydration and volume reduction.

[0003] The reason for this is that the structure and extrusion method of traditional extrusion devices are relatively simple. They mostly adopt top-down hydraulic unidirectional extrusion, which makes it difficult to flexibly adjust the extrusion strategy according to the different characteristics and moisture content of the waste. This makes it impossible to meet the requirements of efficient filtrate discharge, thereby reducing the quality of waste recycling.

[0004] Therefore, this utility model proposes an integrated treatment device for landfill leachate. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated landfill leachate treatment device to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: an integrated landfill leachate treatment device, including a machine body, a filter plate inside the machine body, two movable plates for squeezing landfill waste inside the machine body, and a squeezing plate inside the machine body that squeezes the landfill waste in a vertical direction. A squeezing unit is provided on the side of the machine body to drive the two movable plates to move closer together.

[0006] Preferably, the extrusion unit includes two connecting rods located on the side of the movable plate, which are fixedly connected to the two movable plates respectively. The side of the machine body is provided with L-shaped rod one and L-shaped rod two. The ends of L-shaped rod one and L-shaped rod two are fixedly connected to the two connecting rods respectively. A gear is provided between L-shaped rod one and L-shaped rod two, and the surfaces of L-shaped rod one and L-shaped rod two have a toothed row that meshes with the gear. A fixed shaft is provided inside the gear. The fixed shaft is fixedly connected to the machine body through a bracket. A connecting strip is provided above L-shaped rod two, and an electric push rod is provided above the connecting strip.

[0007] Preferably, the filter plate has a disc inside, two insert rods above the disc, a turntable at the bottom of the disc, and a motor on the side of the machine body. The turntable and the motor are driven by a belt pulley.

[0008] Preferably, the motor is electrically connected to the electric push rod, and when the electric push rod first drives the L-shaped rod two to reset, the motor receives a start electrical signal sent by the electric push rod.

[0009] Preferably, the overall shape of the movable board is raised, and the turning area of ​​the movable board is sloping.

[0010] Preferably, the bottom of the extrusion plate includes multiple equidistant protrusions with sharp ends, and the extrusion plate is powered to move downward by a hydraulic rod.

[0011] This utility model has at least the following beneficial effects:

[0012] In this invention, the extrusion unit brings two movable plates close together to initially compress the waste inside the machine body until the two movable plates come into contact and stop. Then, the hydraulic rod is driven to push the extrusion plate downward, further reducing the volume of the already compressed waste. The waste is compressed from different directions, ensuring that the requirements for high-efficiency filtrate discharge are met, thus improving the quality of waste recycling. In addition, after the electric push rod is first extended and drives the L-shaped rod to reset, the motor will drive the disc to rotate, allowing the disc to rotate the initially compressed waste by 90 degrees. At this time, the electric push rod drives the two movable plates to compress the waste on different surfaces again. Combined with the secondary compression of the extrusion plate, a higher waste filtrate rate can be obtained, further improving the quality of waste recycling. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an integrated landfill leachate treatment device, comprising:

[0020] Example

[0021] The machine body 1 has a filter plate 2 inside and is fixedly connected to it. Inside the machine body 1 are two movable plates 3 that squeeze the waste. The overall shape of the movable plate 3 is convex. The turning area of ​​the movable plate 3 is sloping. This sloping shape can apply a sloping squeezing force to the waste in an inclined direction when the two movable plates 3 are close to each other, so that the squeezing effect of the waste is better and the filtrate discharge efficiency is improved.

[0022] The machine body 1 is also equipped with a squeezing plate 4, which squeezes the waste in the vertical direction. The bottom of the squeezing plate 4 includes multiple equidistant ridges 17. The ends of the ridges 17 are sharp. This shape can effectively chop the surface of large waste when the squeezing plate 4 squeezes the waste downward, improving the discharge efficiency of the waste filtrate. The squeezing plate 4 is powered to move downward by a hydraulic rod. The top of the hydraulic rod is fixedly connected to the top of the machine body 1. The side of the machine body 1 is equipped with a squeezing unit 5 that drives two movable plates 3 to move closer to each other. After the two movable plates 3 have completed the initial squeezing of the waste, the squeezing plate 4 squeezes the waste in the vertical direction, which further reduces the volume of the waste, meets the requirements of high-efficiency filtrate discharge, and improves the recycling quality.

[0023] The extrusion unit 5 includes two connecting rods 6 located on the side of the movable plate 3, which are fixedly connected to the two movable plates 3 respectively. Both connecting rods 6 are slidably connected to the machine body 1. The side of the machine body 1 is provided with an L-shaped rod 7 and an L-shaped rod 8. The ends of the L-shaped rod 7 and the L-shaped rod 8 are fixedly connected to the two connecting rods 6 respectively. A gear 9 is provided between the L-shaped rod 7 and the L-shaped rod 8. The surfaces of the L-shaped rod 7 and the L-shaped rod 8 have a toothed row that meshes with the gear 9. The gear 9 has a fixed shaft 10 inside and is rotatably connected to it. The fixed shaft 10 is fixedly connected to the machine body 1 through a bracket. A connecting strip 11 is provided above the L-shaped rod 8 and is fixedly connected to it. An electric push rod 12 is provided above the connecting strip 11 and is fixedly connected to it. The side of the electric push rod 12 is fixedly connected to the outer wall of the machine body 1.

[0024] In addition, the filter plate 2 has a disc 13 inside and is rotatably connected to it. Two rods 14 are fixedly connected to the top of the disc 13. A turntable 15 is fixedly connected to the bottom of the disc 13. A motor 16 is provided on the side of the machine body 1. The motor 16 is fixedly connected to the machine body 1 through a bracket. The turntable 15 and the motor 16 are mutually driven by a pulley. The motor 16 is electrically connected to the electric push rod 12.

[0025] Working principle:

[0026] After the waste is fed into the machine body 1 through the inlet, the electric push rod 12 is driven to move the L-shaped rod 8 laterally through the connecting strip 11. Under the meshing transmission of the L-shaped rod 8 and the L-shaped rod 7 with the gear 9, the L-shaped rod 7 will move closer to the L-shaped rod 8, which will then move the connecting rod 6 and the movable plate 3 at their respective ends closer to each other, thus initially squeezing the waste inside the machine body 1 until the two movable plates 3 come into contact and stop. While the two movable plates 3 are stationary, the hydraulic rod is driven to push the squeezing plate 4 downward, further reducing the volume of the already shrunk waste. The waste is squeezed from different directions, which can ensure that the requirements for high-efficiency filtrate discharge are met and improve the quality of waste recycling.

[0027] Furthermore, after the electric push rod 12 is first extended and drives the L-shaped rod 8 to reset, the motor 16 will receive a start electrical signal sent by the electric push rod 12. The motor 16 will drive the turntable 15 to rotate a quarter turn through the pulley, thereby causing the disc 13 to rotate. The two insert rods 14 can provide a certain degree of stability for the waste, so that the disc 13 can drive the waste after the initial compression to rotate, so that the waste rotates 90 degrees as a whole. At this time, the electric push rod 12 is used to drive the two movable plates 3 to move closer to each other and squeeze different surfaces of the waste again. With the secondary compression of the compression plate 4, a higher waste filtrate rate can be obtained, further improving the recycling quality of the waste.
