The invention relates to a drum screening and crushing device. The drum screening and crushing device comprises a tank body installed on a machine frame, rails are disposed on the periphery of the tank body, and a drum screen is installed in the tank body and driven by a drive device on the machine frame. The front end of the drum screen is a conveying belt feed end, and the rear end of the drum screen is a discharge end. The portion, under the lower side of the drum screen, of the machine frame is provided with an undersize material outlet. A crushing unit is arranged at the conveying belt feed end, and an oversize material outlet is arranged at the discharge end. The crushing unit comprises a crushing knife roller arranged at the front end of the drum screen and a crushing motor used for driving the crushing knife roller, and the crushing motor is installed on the machine frame through a support. The crushing unit is arranged at a feed port of the drum screen and conducts preliminary crushing on garbage materials, so that material screening is facilitated, the structure and installation location design of the crushing unit is reasonable, and the crushing effect of the crushing unit is good; a frustum-shaped structure is adopted for the drum screen, so that the drum screen is reasonable in structure, convenient to install and high in screening work stability.
Description
technical field [0001] The invention relates to domestic waste treatment equipment, in particular to a device for screening waste. Background technique [0002] A large amount of garbage generated in daily life is very inconvenient to handle due to its many components and large discharge volume. If it is not disposed of in time or improperly disposed of, it will cause pollution and affect environmental sanitation. Garbage disposal is the removal of garbage, harmless treatment and rational utilization. At present, it mainly relies on landfill, composting and incineration. The above garbage disposal methods all have shortcomings. During landfill and composting, there will still be a large number of bacteria, viruses, heavy metals, etc. in the garbage. For non-perishable garbage, the cycle is too long, and garbage leakage will cause long-term pollution. Groundwater resources bring great harm to the environment; during incineration, the burning of garbage will produce a large ...
