Technical Field

[0001] The utility model belongs to the field of solid waste treatment, in particular to a solid waste treatment screening device. Background Art

[0002] Solid waste refers to solid or semi-solid waste materials generated in the process of production, life and other activities that have lost their original utilization value or have not lost their utilization value but have been discarded or abandoned. Since solid waste is often very harmful, such as polluting soil, water sources and air, it needs to be scientifically managed and disposed of. At present, all countries have formulated corresponding solid waste management regulations and policies to regulate the collection, transportation, treatment and disposal of solid waste to ensure the safety of the environment and human health.

[0003] When handling solid waste, in order to facilitate waste treatment and reduce waste of resources, it is usually necessary to screen the waste. When using a filter to screen the waste, the mesh size of the filter is usually fixed, and it is difficult to adjust the mesh size as needed, which makes it inconvenient to screen the waste.

[0007] Preferably, a fixing plate is detachably mounted on the end of the fixing frame; the fixing plate is arranged at a position of the fixing frame away from one end of the rotating shaft; this enables the fixing frame to support the filter rod more stably.

[0008] Preferably, a guide rod is fixed inside the fixing frame; the guide rod is arranged in parallel inside the fixing frame; the filter rod is slidably connected to the guide rod; this can make the filter rod more stable when placed inside the fixing frame.

[0009] Preferably, the fixing bolt is internally slidably connected to a sliding plate; a spring is fixedly connected between the top of the sliding plate and the inner wall of the fixing bolt; a connecting rod is fixedly connected to the bottom of the sliding plate; and a contact block is fixedly connected to the bottom of the connecting rod; the friction between the fixing bolt and the threaded hole can be made greater, so that the fixing bolt has a better fixing effect on the sliding block.

[0010] Preferably, a positioning block is fixed to the rotating shaft of the eccentric wheel; the positioning block is rotatably connected to an internal position of the screening frame; the eccentric wheel is less likely to tilt during rotation, making the rotation of the eccentric wheel more stable.

[0011] Preferably, a plurality of anti-wear balls are provided between the screening frame and the positioning block; the side walls of the anti-wear balls are in contact with the side walls of the screening frame and the positioning block; the sliding friction between the screening frame and the positioning block can be converted into rolling friction, thereby reducing the wear between the screening frame and the positioning block.

[0014] 2. The solid waste treatment and screening device described in the utility model, when the sliding block drives the filter rod to be inserted into the interior of the fixed frame, the filter rod is limited by the structural design of the guide rod, thereby realizing a more accurate function when the filter rod and the sliding block are inserted into the interior of the fixed frame.
