Detailed Description
The technical solution of the present invention is further described and illustrated by the following specific embodiments.
Example (b):
a household garbage screening device is shown in figure 1 and comprises a flotation tank 1 with a funnel-shaped bottom, a feeding device 2, a first discharging device 3 and a second discharging device 4. The garbage obtained in the previous process is conveyed to the flotation tank 1 through the feeding device 2, the garbage is classified through screening of the flotation tank 1, and the classified garbage is discharged from the first discharging device 3 and the second discharging device 4 respectively. According to the screening method, according to different densities of different domestic wastes, components such as ceramics, glass and metal with higher densities can be screened from the domestic wastes through the flotation tank, and most organic matters such as plastic paperboards are reserved, so that the subsequent treatment and utilization are facilitated.
The feeding device 2 is connected with the flotation tank 1 from the outside, the lower end of the first discharging device 3 is arranged at the middle upper part of the flotation tank 1, and the second discharging device 4 is arranged at the bottom of the flotation tank 1; the flotation tank 1 is provided with an inclined bottom, a second discharge hole 5 is formed in the lower position of the bottom of the flotation tank 1, and a second discharge device 4 is arranged at the second discharge hole 5.
