SYSTEM FOR SQUEEZING, SMASHING AND WINNOWING MUNICIPAL SOLID WASTE

摘要

The invention discloses a system for squeezing, smashing and winnowing municipal solid waste (MSW). The system comprises a primary squeezing and smashing, device and a secondary smashing and winnowing device. The system of the invention has good effect m squeezing, smashing and winnowing, can greatly reduce the water content of MSW and efficiently separate the MSW into combustible matters and non-combustible matters, so as to facilitate further subsequent utilization of the municipal waste; moreover, an upper jaw of a jaw crusher is connected with a spring device, so that the squeezing pressure, smashing effect and processing capacity of the jaw crusher can be adjusted according to the amount of the MSW. In addition, the system of the invention is further provided with emergency brake switches, spring protection devices and a sieve, so as to ensure the stability and the reliability of the system.

主权项

1. 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, anda 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 devicea 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,a fin mounted on left of the winnowing chamber, andan arc-shaped separation plate which separates waste into relatively light combustible matter and light combustible matter, the arc-shaped separation plate being mounted on right 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.
