0.5cm, the gas of lower floor enter air bag by stomata, and there is exhaust outlet on air bag top.
The cutting tool of broken unit can be changed according to feed material, and blade uses alloy-steel blade, moving knife and stationary knife
Between leave gap, the gap between the moving knife and stationary knife of more than 20HP disintegrating machines is set as 0.8mm, below 20HP disintegrating machine
Moving knife and stationary knife between 0.5mm.
Conveyer belt in electromagnetic absorption device can be overturn by external button control.
Spray head in gas purifying equipment sprays water smoke, and leacheate is sodium hydroxide 10%+ alcohol 95 %, and the two ratio is
1:1。
The advantage of the invention is that:
(1)The system realizes the cycling and reutilization of plastic garbage, and changing waste into resources is realized while discarded object is reduced.
(2)All steel welding frame, sturdy and durable, appearance closure designs, waterproof, weight of equipment is light, easy-dismount design, clearly
Wash easy to maintenance.
(3)Low energy, highly skilled, stable equipment operation, plastic garbage percentage of damage is high, up to more than 99.7%.
(4)Equipment environmental protection, noise is low, meets relevant criterion and the requirement of country.
(5)Whole system is controlled by PLC circuit, and the automation of the key of whole system one can be achieved.
