The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.

Embodiment 1; The utility model comprises that to material conveying device, breaker, pneumatic separator, impurity removal means, Granulation Equipments, control system the control system links with giving material conveying device, breaker, pneumatic separator, impurity removal means and Granulation Equipments respectively; Adopt belt conveyer to material conveying device; Breaker adopts the zigzag rotating blade; Pneumatic separator comprises hot-blast stove, air blast, and impurity removal means comprises at the bottom of the pneumatic separator thorax that Granulation Equipments comprises screw feeding device, tamping equipment and the prilling granulator of installing on the spout; The control system comprises industrial computer and induction installation; Also can establish heater in the exit of blast apparatus.It mainly is made up of 6 parts:

1. give material conveying device.Utilize the principle of belt conveyer under the control of computer, the refuse plastic that the soot sorts out to be delivered to crushing system; Through the mensuration to moisture, impurity equal size, computer realization guarantees the uniformity of feed and the drying of sheet stock to the control of belt conveyor speed.

2. impurity removal means.Mostly refuse plastic is plastic sheeting, packaging bag, and the inside is enclosed with metal object and silt and domestic refuse, and system adopts the zigzag rotating blade that refuse plastic is torn; Make the film sheet; Through air blast sheet stock is delivered to drying system, because the plastics sheet stock is different with the density of impurity, the sheet stock that density is little is seen off; The impurity that density is bigger falls into removal of impurity system, has realized fragmentation and the deimpurity process first time like this.

3. pneumatic separator.Utilize heat that hot-blast stove produces under the conveying of air blast to the refuse plastic sheet stock heat air delivery in the equipment thorax; And through adjusting the angle of air-supply; Make in the thorax refuse plastic sheet irregular stressed, form random seething, sub-elect plastics according to the difference of the density of plastics and impurity (mainly being metal object and silt and domestic refuses etc. such as iron, copper, aluminium); Impurity is at the bottom of falling within thorax under the effect of deadweight, and the steam fog centralized collection enters in the flue.Computer system is monitored impurity, moisture content in the refuse plastic sheet stock automatically, and the inlet of time, air-supply blast and hot blast is seethed in control automatically.The plastics sheet stock of handling through native system does not have metal impurities basically, and moisture is 1.5～2.5%, and the content of silt can be satisfied with the needs that my Company products is produced fully about about 2%.

4. impurity discharger.Through the control of control system, under the screw propulsion effect of spiral tapping machine, release outside the thorax in order, and the manual regular collection, focus on separating the impurity fall within the bottom of impurity removal means and the pneumatic separator thorax automatically.

5. Granulation Equipments.Native system utilizes traditional screw granulation mode extruding pelletization, and spout is equipped with screw feeding and tamping equipment.Its process in case temperature is too high, makes plastics burn carbonization through the strict control of computer temperature and reinforced speed.

6. control system.Disposable disposal of refuse plastics special equipment utilizes the technological parameter of each operation of computer control.Use through the native system Development of Software, realized to impurity, moisture content in the refuse plastic processing procedure automatic monitoring and feeding coal, hot blast feeding amount, seethe the time and seethe the automatic control of blast, and realized the intelligent management of process complete.Consult Fig. 1.

Embodiment 2, and the use technology of the utility model comprises that plastics separate with impurity, operations such as plastics are air-dry, granulation; Earlier the refuse plastic raw material is sent into and be broken into the sheet material in the disintegrating apparatus; Then the refuse plastic sheet stock after the fragmentation is sent in the pneumatic separator; The plastics sheet stock and in impurity along with the screw propulsion of hot-air flow; Because of in progradation, can producing vibration, and since the density variation of plastics and impurity select the plastics sheet stock and remove impurity at diverse location thereby plastics and impurity are broken away from fully and descend slowly and lightly respectively; Because moisture content quickens vaporization under the effect of hot blast, the dry clean plastics sheet stock that again selection by winnowing is come out is delivered to Granulation Equipments and is processed the particle that can utilize again simultaneously.Disintegrating apparatus, pneumatic separator and Granulation Equipments link with the control system respectively, through the setup parameter of control system, realize impurity, the isoparametric automatic monitoring of moisture content and intelligent management in the raw material.Also can be provided with many grades of raw material discharging openings at pneumatic separator, with the batch mixing after the fragmentation through blowing choosing, thereby the refuse plastic of different specific weight or density is classified.And with comprising metal object, the recycling of glass centralized collection in the impurity that sorts out, silt and domestic refuse etc. is carried out harmless treatment, thereby realized that plastics separate with impurity, plastics oven dry, granulation integrated.In realizing above process; Independently developed computer software; Through controlling the setup parameter of each system, realized automatic monitoring and intelligent management to material such as impurity, moisture content in the raw material, make the plastic granule that produces satisfy the production needs of product fully.Consult Fig. 1, all the other are with embodiment 1.

Embodiment 3, and the control system of the utility model links with giving material conveying device, breaker, pneumatic separator, impurity removal means and Granulation Equipments respectively; Utilize the principle of belt conveyer under the control of computer, the refuse plastic that the soot sorts out to be delivered to crushing system; Through mensuration to moisture, impurity equal size; Computer realization guarantees the uniformity of feed and the drying of sheet stock to the control of belt conveyor speed; Adopt the zigzag rotating blade that refuse plastic is torn; Make the film sheet; Through air blast sheet stock is delivered to drying system, because the plastics sheet stock is different with the density of impurity, the sheet stock that density is little is seen off; The impurity that density is bigger falls into removal of impurity system, realizes broken and the process of the removal of impurity for the first time; Utilize again heat that hot-blast stove produces under the conveying of air blast to the refuse plastic sheet stock heat air delivery in the equipment thorax; And through adjusting the angle of air-supply; Make in the thorax refuse plastic sheet irregular stressed, form random seething, sub-elect plastics according to the difference of plastics and impurity density; Impurity is at the bottom of falling within thorax under the effect of deadweight, and the steam fog centralized collection enters in the flue; Computer system is monitored impurity, moisture content in the refuse plastic sheet stock automatically; Automatically the inlet of time, air-supply blast and hot blast is seethed in control; Control through the control system; Under the screw propulsion effect of spiral tapping machine, release outside the thorax in order separating the impurity fall within the bottom of impurity removal means and the pneumatic separator thorax automatically, and regularly collect, focus on; Adopt screw rod granulation mode extruding pelletization.Consult Fig. 1, all the other are with above-mentioned embodiment.
