The rotational flow sorting cleaning device of waste plastics fragment
Technical field
The utility model relates to recovery and the cleaning technique of waste plastics, specifically, relates to a kind of rotational flow sorting cleaning device of waste plastics fragment.
Background technology
Along with the continuous increase of plastic products consumption figure, waste plastics also is on the increase.These waste plastics will certainly destroy environment if processing is improper, destroy the ecological balance, finally threaten human existence.
Existing waste plastics is mainly handled in the following way: after the waste plastics recovery, classify earlier, be broken into fragment, clean up, again with the fragment fusion, make new plastic raw materials particle and finished product, realize regeneration.
In the existing equipment, there is not plastics rotational flow sorting cleaning device.
General separating plastic all adopts the mode of flotation sorting, and this method inefficiency is with high costs.Density is carried out the flotation cleaning greater than the present halide salt solution that uses usually of the waste plastics fragment of water as fluid media (medium), be difficult to handle with complete fluid media (medium), bring pollution to environment after the discharging.
The silt of waste plastics fragment and the cleaning treatment of impurity are mainly undertaken by artificial or mechanical mode.For the cleaning of density greater than the waste plastics fragment of water, a kind of method is to need could realize the flotation cleaning with the density of the halid aqueous solution with the increase fluid media (medium); A kind of method is in sink (device) bottom agitating device to be set to clean under water, is difficult to separate waste plastics fragment, silt and impurity.
Therefore, need to introduce special sorting cleaning device, realize that density is greater than the automatic sorting less than waste plastics fragment, silt and the impurity three class materials of fluid media (medium) of the waste plastics fragment of fluid media (medium), density, simultaneously the waste plastics fragment is cleaned, realize automation and the serialization of operating process, effectively improve working (machining) efficiency.
The utility model content
At the technical problem that exists in the prior art, the purpose of this utility model is: the rotational flow sorting cleaning device that the waste plastics fragment of a kind of simple in structure, sorting of can be continuously produced, efficiently realizing the waste plastics fragment and cleaning is provided.
In order to achieve the above object, the utility model adopts following technical scheme:
The rotational flow sorting cleaning device of waste plastics fragment is characterized in that: comprising: tapered shaped can, water inlet pipe, silt separation net, its top feed mouth, top discharge pipe and sidewall discharge nozzle; Tapered shaped can integral body is in an inverted cone, and the bottom is provided with sediment ejection opening; The silt separation net that only allows silt and impurity pass through is positioned at tapered shaped can, wide at the top and narrow at the bottom, the upper end open of shape; Water inlet pipe inserts the sidewall of tapered shaped can and stretches in the silt separation net along tangential direction; Its top feed mouth is positioned at the top of tapered shaped can; The top discharge pipe is positioned at the top of tapered shaped can; The sidewall discharge nozzle connects the sidewall of tapered shaped can and stretches in the silt separation net along the tangential direction of tapered shaped can.After adopting this structure, realize that density is greater than the automatic sorting less than waste plastics fragment, silt and the impurity three class materials of fluid media (medium) of the waste plastics fragment of fluid media (medium), density, simultaneously the waste plastics fragment is cleaned, realize automation and the serialization of operating process, effectively improve working (machining) efficiency.Leave little gap between the upper end-face edge of silt separation net and the inwall of tapered shaped can, from top to bottom, the gap between the outer wall of silt separation net and the inwall of tapered shaped can increase gradually.
