<p>A shutoff valve-regulated pneumatic feces extraction and feces discharging system comprising a pneumatic transportation apparatus (1), multiple shutoff valves (5, 13, and 14), a carrier tank (11), and several pipes. An air intake pipe (4) is arranged on an air intake, an air feeder pipe (12) is arranged on an air feeder end of the pneumatic transportation apparatus (1), and the air feeder pipe (12) is operatively connected to a feces storage apparatus. A first shutoff valve (5) is arranged on a first pipe (7), a first end of the first pipe (7) is connected to the air intake pipe (4), and a second end of the first pipe (7) is connected to the carrier tank (11). A third shutoff valve (14) is arranged on the air feeder pipe (12). Compared to vacuum feces extraction system apparatus, the system allows for simplified extraction and discharging system structure, for supporting the feces storage apparatus to implement pneumatic feces extraction and forced feces discharging, for the feces extraction process to be free of foul odor leakage, for environmental protection, for simplified maintenance and operation, for increased depth of feces extraction, for reduced requirements for the material and processing of the carrier tank, and at the same time for reduced manufacturing costs of apparatus.</p> |
