To the screening plant.Wherein screening plant is the double-deck circular vibrating screen, and the material slideway includes the first separating material slideway, second point
From material slideway and returning charge slideway.The working principle of this kind of screening plant is that different size of sieve pore is opened up on two-layer cylinder, is broken
Building waste after broken is sieved via sieve pore, and the type as included in building waste is more, is sieved by volume
Mode material can not accurately be separated.
In view of the above-mentioned problems, the patent of invention that Authorization Notice No. is CN201124159Y discloses a kind of garbage disposal screening
Device, tossed device including conveying garbage material and the wind power machine that material is raised and shed using wind-force, it is described to shed dress
It sets including belt conveyor, the wind power machine includes centrifugal blower and blower, it is characterised in that: the sieving garbage device
It further include that this roller shed again can be carried out to the material through wind-force primary election, the roller is located at belt conveyor and sheds end lower section
And it is located at and sheds on the fall trajectory of material.It is as follows that when carrying out screening work, there are problems: first is that roller is in screening
Relay-type, i.e., material to be sieved must fall directly into the effect that water conservancy diversion is just able to achieve on roller, without dropping down on roller
Material cannot achieve screening, influence screening effect；Second is that roller is collided with material for a long time, service life is short；Third is that due to roller
It must be positioned at " belt conveyor is shed end lower section and is located at and sheds on the fall trajectory of material " and be just able to achieve guide functions, therefore
The angle of tossed device and wind power machine also must be relatively fixed, and the adaptability of equipment is not strong；In addition this kind of garbage disposal screening
Device is mainly used for handling house refuse, and can be with this large amount of dust in screening process when sieving building waste, should
Equipment cannot achieve the recycling of dust, processing.
Summary of the invention
In order to overcome the shortcomings in the prior art, the present invention provides a kind of achievable building waste screening plant.
To achieve the above object, The technical solution adopted by the invention is as follows: a kind of building waste screening plant, including sorting
