Description
Technical field
The present invention relates to screening installation field, more particularly to a kind of high-efficient low-noise mixed plastic electrostatic separator.
Background technology
As plastic products consumption figure constantly increases, waste plastic is also on the increase, and China's waste plastic is mainly at present
Plastic sheeting, plastic package box, container and daily plastic product, automotive plastic annual consumption in China's is up to 1,500,000 tons in addition,
Electronic apparatus and household electrical appliances are with applying mechanically plastics annual consumption up to more than 400 ten thousand tons, and these product rejection thickness are into the important of waste plastics
One of source.It is reported that domestic waste plastics in 2015 is up to 30,000,000 tons.The rise of global crude oil price, as petroleum derivative
One of plastic products price naturally also when the river rises the boat goes up, the regeneration of waste plastics has been also increased to primary position.Tradition
Waste plastics classification be mainly artificial screening and salt solution（Density different classifications）.Artificial screening waste substantial amounts of manpower and materials and
Area of mill site is big, and operating efficiency is low.According to pneumatic separator, then there is also have purity bottom, high energy consumption, bulky
Shortcoming.
The species of plastics mainly has HIPS, ABS, PC, PP etc., and different types of plastics can not be directly used in mixed way, if
Do not classify and directly recycled, serious destruction can be caused to the mechanical property of plastics in itself, greatly reduces its use
Value and economic value, and the value between variety classes plastics also has very big difference.On the other hand, waste plastic is difficult to
Degraded, if directly discarded can pollute to environment, recycled plastic carries out regeneration and granulation to it, can not only reduce environment dirt
Dye, can also create new value.Therefore need to carry out category sorting, mesh to different plastics when carrying out the recovery of waste plastic
Preceding conventional method for separating includes density separation, solvent sorting, vibrations sorting etc., but above-mentioned method for separating is required for carrying out waste water
Processing, secondary pollution can be caused to environment by dealing with improperly, and need to carry out plastics the operation such as cleaning and dewatering, increase after sorting
The complexity and uncontrollability of sorting flow.
Electrostatic separation refers to carry out different material point machinery of first (choosing) using the attached effect of electrostatic.Electrostatic separation is
Reach sorting purpose using material difference electrical in high voltage electric field, when drum barrel of the material by rotation is brought to corona electrode
When in the high voltage electric field of effect, material is reused by various electric power, centrifugal force, gravity.Due to the electrical property of various materials
Track when difference, the difference of stress fall material is different, so as to which metal be separated with non-metal mixture.
