System for squeezing, smashing and winnowing municipal solid waste

A system for squeezing, smashing and winnowing municipal solid waste, comprising:

• a primary squeezing and smashing device including
• a feeding port at a top of the primary squeezing and smashing device,
• a storage bin below the feeding port,
• a hydraulic pushing device provided left of the storage bin,
• a squeezing zone provided right of the storage bin,
• a squeezing and smashing zone provided right of the squeezing zone,
• a discharge port provided right of the squeezing and smashing zone,
• a filter screen mounted at a joint of the squeezing zone and the squeezing and smashing zone,
• a leachate pipeline connected with a bottom of the filter screen, and
• a jaw crusher mounted in the squeezing and smashing zone, a lower jaw of the jaw crusher being provided with apertures through which waste leachate flows down to a bottom surface of the squeezing and smashing zone;
• a secondary smashing and winnowing device including
• a feeding port at a top of the secondary squeezing and smashing device,
• a smashing bin below the feeding port,
• a sieve below the smashing bin,
• a winnowing chamber below the sieve,
• a conveying belt which receives non-combustible matter below the winnowing chamber,
• a slow revolving knife and a fast revolving knife identical in revolving direction and which are arranged adjacent to each other in the smashing bin, the slow revolving knife being mounted below the feeding port, and
• a fan mounted on left of the winnowing chamber;
• and
• a baffle and a baffle conveying belt mounted above the baffle, disposed between the primary squeezing and smashing device and the secondary smashing and winnowing device;
• wherein a first side of the baffle is connected with the leachate pipeline of the primary squeezing and smashing device, and a second side of the baffle is connected with the feeding port of the secondary smashing and winnowing device so that the waste leachate flows to the leachate pipeline;
• wherein a feeding end of the baffle conveying belt is positioned below the discharge port of the primary squeezing and smashing device, and a discharge end of the baffle conveying belt is positioned above the feeding port of the secondary smashing and winnowing device;
• and
• wherein a running direction of the conveying belt of the secondary smashing and winnowing device is opposite to a wind direction of the fan.
