specific Embodiment

[0054] A specific example is as follows:

[0055] In a waste treatment plant with a processing capacity of 10 million tons per day, domestic waste enters the magnetic separation device 1 through the feed port 11 and is conveyed by the feed belt 12. The magnetic separation device is 6m high and has a foul gas collection pipe 13 on the top , the electromagnetic separator 14 and the magnetic separation belt 15 are located at a height of 5.5 meters in the device, and the vertically below 1 meter is a reversing rebound belt conveyor 16. Garbage feed inlet 11 and horizontal plane are 8 degree angles, and feed belt 12 is wide and is 160cm, and metal outlet 17 is positioned at feed inlet 11 just below, and metal feed belt 2 is wide 80cm, and direction is 90 degrees with feed belt. After the garbage is sorted by magnetic separation and reversing rebound, refractory materials such as masonry, glass, shoes, rubber, etc. are transported to the waste line through the waste outlet 18, and t...

Abstract

The invention provides a combined device for sorting toxic and harmful substances in household garbage. The structure of a magnetic sorting device is as follows: two sides of the top are respectively provided with a garbage feeding opening and a waste material outlet, wherein the garbage feeding opening is provided with a feeding belt; a metal discharging opening is arranged below the feeding belt, and a metal material accepting belt is arranged below the metal discharging opening; a waste material opening is connected with a waste material belt; the waste material belt is respectively connected with a material discharging opening and a material outputting belt; an electromagnetic separator is mounted at the upper part in the magnetic sorting device; a magnetic sorting belt is wound around an outer ring of the magnetic separator; a reversing rebound belt is mounted below the magnetic separator; the running direction of the feeding belt is opposite with the running directions of the magnetic sorting belt and the reversing rebound belt; a metal discharging belt is connected with a primary reversing magnetic sorting belt and the primary reversing magnetic sorting belt is connected with a secondary bounce sorting machine and a waste material line belt through a magnetic sorting line belt; and the other end of the magnetic sorting line belt is connected with a primary roller sieve and the primary roller sieve is connected with a primary bounce sorting machine through the secondary bounce sorting machine.

Description

technical field [0001] The invention belongs to the technical field of domestic waste mechanical separation, and in particular relates to a combined device for efficiently sorting toxic and harmful substances in domestic waste. [0002] The present invention also relates to a method for separating toxic and harmful substances in domestic waste by using the combination device. Background technique [0003] With the rapid development of urbanization, the annual output of urban domestic waste in my country is close to 150 million tons, and more than 65% of cities in China have fallen into the predicament of domestic waste siege. Domestic waste not only affects the urban landscape, but also seriously affects people's health. Good health, recycling, reduction, and harmlessness of domestic waste have become important issues in urban environmental protection. [0004] The treatment methods of domestic waste include incineration, landfill, composting, etc. Due to the high moisture ...
