Description

Technical Field

[0001] The utility model relates to the technical field of landfill leachate coarse filtration, in particular to a landfill leachate coarse filtration grid. Background Art

[0002] Leachate is the product of gravity flow of liquid in a landfill, mainly derived from precipitation and the inherent water in the garbage itself. Since there are many factors that may affect the properties of the leachate during the flow of liquid, including physical factors, chemical factors, and biological factors, the properties of the leachate vary within a fairly large range. The leachate from urban landfills is a high-concentration organic wastewater with complex components. If it is directly discharged into the environment without treatment, it will cause serious environmental pollution. For the purpose of protecting the environment, it is essential to treat the leachate. In the process of garbage disposal, coarse filter screens are usually used to filter out the leachate from the garbage, collect it, and finally treat it uniformly.

[0003] Since garbage has different shapes and sizes, when filtering garbage, grids with different apertures are often stacked together for filtering. However, the gaps between the existing grids are large, and leachate is easy to flow out of the gaps, causing pollution to the environment. In addition, garbage expands after contacting water, and the garbage has more water inside and a larger volume, which leads to a large amount of residual water in the garbage, occupies a large space, and requires frequent cleaning by staff. Therefore, a garbage leachate coarse filtration grid is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a landfill leachate coarse filter grid to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A landfill leachate coarse filtration grille comprises a support frame, the bottom end of the support frame is fixedly connected with a vertically arranged support leg, the inner side of the support frame is fixedly connected with a water collecting tank, the bottom end of the water collecting tank is fixedly connected with a valve that penetrates the inner side of the water collecting tank, the top end of the support frame is fixedly connected with a vertically arranged slide rail, the inner side of the slide rail is slidably connected with a slider, the side of the slider away from the slide frame is fixedly connected with a fixed frame, the inner side of the fixed frame is fixedly connected with a grille, the top end of the fixed frame is fixedly connected with a first sealing frame, the bottom end of the fixed frame is provided with a sealing groove, and the top end of the water collecting tank is fixedly connected with a second sealing frame.

[0007] Preferably, a circular hole penetrating the fixed frame is provided on one side of the fixed frame, a screw is provided on the inner side of the circular hole, one end of the screw is rotatably connected to a bearing located on the inner side of the fixed frame, a side of the bearing away from the screw is fixedly connected to a clamping plate, a threaded cylinder is bolted on the outer side of the screw, and an end of the screw away from the bearing is fixedly connected to a handle.

[0008] Preferably, the number of the circular hole, the lead screw, the bearing, the clamping plate, the threaded barrel and the handle are all six, the clamping plate and the fixed frame are connected by sliding connection, and the threaded barrel is fixedly connected to the outside of the fixed frame.

[0009] Preferably, the number of the legs is four, the legs are evenly distributed at the bottom edge of the fixed frame, the number of the slide rails and the number of the slide blocks are two, and the apertures of the grilles are arranged to decrease from top to bottom.

[0010] Preferably, the number of the fixing frame, the grille, the first sealing frame and the sealing groove are all three, the first sealing frame and the second sealing frame are the same in shape and size, and the volume of the sealing groove is larger than that of the first sealing frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the water collecting box, valve, slide rail, slider, fixed frame, grille, first sealing frame, sealing groove and second sealing frame are arranged to prevent the leachate from flowing out from the gaps between the grilles and causing pollution to the environment. First, grilles of different apertures are stacked together according to needs, and the slider is inserted into the inner side of the slide rail at the top of the support frame. At this time, the fixed frame falls until the sealing groove is tightly fitted with the second sealing frame at the top of the water collecting box. Then, the grille is installed, and the remaining sealing grooves are tightly fitted with the first sealing frame. Then, the valve is connected to the subsequent sewage treatment device, and the garbage is transported to the top of the equipment. The grille can filter out the leachate in the garbage, and the leachate can enter the inner side of the sewage treatment device through the water collecting box and the valve;

[0013] 2. In the utility model, the circular hole, screw, bearing, clamping plate, threaded barrel and handle are provided, so that the water inside the garbage can be squeezed out, the space occupied by the garbage can be reduced, and the working efficiency of the operators can be improved. After the garbage is poured into the inside of the fixed frame, the handle is turned, and the screw is continuously rotated and moved inside the circular hole on one side of the fixed frame due to the limitation of the threaded barrel, and the clamping plate located on one side of the bearing can slide inside the fixed frame, thereby squeezing the garbage inside the fixed frame, squeezing out the water inside it, and compacting the garbage, thereby reducing the number of times the staff cleans the garbage.
