The municipal waste disposal device comprises a conveyor and a screening device. The conveyor comprises a conveying belt, the screening device is provided with a cavity, wherein openings are formed in the two ends of the cavity, and no less than two semi-circle-shaped toothed belts are arranged at the bottom of the cavity wall of the cavity; coaxial rotating drums are arranged in the toothed belts, toothed rings are arranged in the circumferential directions of the rotating drums, the toothed rings are engaged with the toothed belts, working chambers are formed in the rotating drums, and one end of the conveying belt extends into the working chambers; a filter screen and two baffle rings are arranged. in the circumferential direction, on the drum wall of each rotating drum, the filter screens communicate with the working chambers, and each filter screen is located between the corresponding two baffle rings; circular grooves are formed in the cavity wall of the cavity, the baffle rings are rotatably clamped in the circular grooves, first discharging holes are formed in the bottom end of the circular grooves, and the first discharging holes correspond to the filter screens up and down; and a gear is arranged at the top of the screening device, the gear is engaged with the toothed rings, the gear is connected on a driving rod in a sleeving mode, and the driving rod is connected with a first motor. According to the municipal waste disposal device, a mode of rotary screening is adopted, and municipal waste can be well screened.

Description

technical field [0001] The invention belongs to the technical field of garbage disposal devices, and in particular relates to a municipal garbage disposal device. Background technique [0002] Municipal waste is a mixture of solid waste in cities, including industrial waste, construction waste and domestic waste. The quantity, nature and degree of environmental pollution of industrial waste residues vary greatly, so they should be managed uniformly, and placed in designated areas by each factory directly or after treatment to meet the discharge standards according to different situations. Construction waste is generally non-polluting solid and can be disposed of by landfill. Household garbage is the solid waste generated by people in daily life. It has various types, including organic matter and inorganic matter. It should be classified, collected, cleared, transported and treated. [0003] At present, there are three main ways to deal with urban garbage in the world: 1. S...

Problems solved by technology

[0003] At present, there are three main ways to deal with urban garbage in the world: 1. Sanitary landfill is the main way of global garbage treatment at this stage. The disadvantage is that the landfill site not only consumes land resources, but also pollutes the ecological environment, especially for groundwater and surface Water and air pollution are serious, and artificial anti-seepage technical measures are expensive; 2. Garbage incineration is suitable for areas where sanitary landfills are scarce and economically developed. Environmental pollution, and burning of recyclable and valuable materials; 3. The high-temperature composting and anaerobic digestion of organic waste to produce biogas has the disadvantages of occupying a large area, difficult to remove the remaining residues, and secondary pollution to the environment

[0004] In the process of municipal waste classification, it is usually necessary to screen the waste, and the current screening machine is generally vibrating, and the types of municipal waste are too diverse, some are heavy, some are light, some are large, and some are small, resulting in vibration Type screening machine is difficult to screen optimally

[0005] In the patent document with the publication number CN203620930U, a vibrating screen structure applied to the technical field of municipal waste treatment devices is disclosed. The vibrating screen structure includes a vibrating screen body, a rapping motor, and the rapping motor is connected to the vibrating screen body. The vibrating screen body is a hollow box-type structure, the vibrating screen body is equipped with a screen mesh, and a plurality of openings are arranged on the side of the vibrating screen body, and the bolts passing through the openings are connected with the bolt holes on the screen. The vibrating screen structure applied to the municipal waste disposal device can ensure that the screen mesh will not fall off from the vibrating screen body during the working process of the vibrating screen structure, the screen mesh will not fall off, and the rapping motor will not fall off. In order to avoid a great impact on the field work of the vibrating screen structure; but this utility model still adopts the method of vibrating screening, which is difficult to better deal with urban waste
