Embodiment Construction

[0017] refer to figure 1 An example of application of the device and method is illustrated.

[0018] The collected municipal solid waste is sent into the drum through the feeding port, and driven by the rotation of the deflector, the domestic solid waste spirally moves forward in the drum. Under the action of gravity and centrifugal force, domestic garbage with a particle size of less than 80mm passes through the screen hole and enters the under-screen material hopper, while domestic garbage with a particle size larger than 80mm cannot pass through the screen hole and continues to turn and move forward in the drum until it enters the screen. until the particle size is lower than 80mm, it can pass through the sieve hole and enter the under-screen material hopper for the next step of processing. When part of domestic garbage blocks the screen hole or adheres to the outer wall of the cylinder, the telescopic roller brush and scraper move to contact with the drum, which can effec...

Abstract

The invention relates to a trommel screen device and a method used for sorting domestic garbage. The device comprises a roller brush, a roller, a speed reducer, a motor, a scraping plate, a base, screen meshes, a guide plate, a screening hopper and a riddling outlet, wherein the screen meshes are circular holes, the aperture is 80mm, and the aperture ratio is 75 to 85 percent; both sides of equipment are respectively provided with the telescopic roller brush and the scraping plate, which can clear obstacles in the screen meshes and burs outside the roller; and the entire trommel screen deviceis horizontally arranged, the guide plate is arranged inside the roller, and the domestic garbage in the roller turns and moves forward along the guide plate. When the device is used for sorting the domestic garbage, the rotational speed of the trommel screen is controlled to be 10 to 20r / min, and the sorting efficiency of the domestic garbage with the grain diameter below 80mm is as high as 93 percent. The domestic garbage sorting method involved with the invention has high efficiency, low energy consumption and easy maintenance.

Description

technical field [0001] The patent of the present invention relates to a device and method for separating and sorting solid waste, in particular to a device and method for sorting domestic waste. Background technique [0002] At present, the annual output of domestic waste in my country is close to 150 million tons. About 2 / 3 of the cities in China have fallen into the predicament of domestic waste siege, which not only affects the urban landscape, but also seriously affects people's health. Domestic waste has become a thorny issue in urban development. . [0003] In order to protect the living environment of human beings, the treatment of domestic waste is becoming more and more important. At present, the treatment methods of urban domestic waste include incineration, landfill and composting. Due to the large difference in particle size, complex composition and high moisture content of urban domestic waste, sorting must be carried out before incineration, landfill and compos...
