The pig toilet comprises isolated iron pipes supported by food stands with proper height. The manure recovering cart is composed of a hand cart fixedly equipped with a manure sucking cylinder. The bottom in manure sucking cylinder is equipped with a unique air-operated diaphragm pump to send the urine and excrement of pig in manure sucking cylinder to anaerobic fermentation tank to store and to produce organic manure pile.    USE - A device for deodorizing a piggery.    ADVANTAGE - The organic manure pile is sent to an organic fertilizer factory through a liquid manure cart to produce organic fertilizer. In the whole process, the urine and excrement are in a sealing system, thus there is no smell of pig manure spilling so as to achieve the target of deodorization in piggery.    DETAILED DESCRIPTION - A piggery deodorizing device comprises a pig toilet, a pig manure recovering cart, a manure collecting passage and an anaerobic fermentation tank. The pig toilet comprises isolated iron pipes supported by food stands with proper height. The pig toilet is provided at a corner or proper position in the piggery. The manure recovering cart is composed of a hand cart fixedly equipped with a manure sucking cylinder. The top portion of the manure sucking cylinder is provided with a vacuum manure sucker. The shoulder of manure sucking cylinder is connected with a manure sucking rod. The vacuum manure sucker sucks the urine and excrement of pig into the manure sucking cylinder. The bottom in manure sucking cylinder is equipped with a unique air-operated diaphragm pump to send the urine and excrement of pig in manure sucking cylinder to anaerobic fermentation tank to store and to produce organic manure pile. Marsh gas can be used and the organic manure pile can be sent to an organic fertilizer factory through a liquid manure cart to produce organic fertilizer.    DESCRIPTION OF DRAWING(S) - The drawing is a perspective view of a piggery deodorizing device.
