Description
Technical field
This utility model relates to field of plastics processing, is specifically related to a kind of plastic grain screening plant.
Background technology
At present in being modified plastic processes, the plastics after modification, are the most all to be set by extrusion
Standby and coordinate extrusion die that plastics are prepared as nutty structure, unified in order to ensure diameter between prepared plastic grain, carry
High product quality, is both needed to carry out sifting sort to prepared plastic grain.
Mostly existing screening plant, be by vibration screen, so that plastic grain is through screen cloth, but owing to just having prepared
Plastics particle temperature is higher, and easily produces electrostatic after plastic warp friction, is therefore carrying out concentration sieve when substantial amounts of plastic grain
When selecting, easily cause sticking together between plastic grain phenomenon, or sticks in screen cloth, thus has a strong impact on the normal of screening operation
Carry out, and reduce efficiency of selecting materials, and cause plastic grain percent defective to increase, simultaneously, in order to plastic grain is dropped
Temperature, in addition it is also necessary to blower fan is set plastic grain is carried out air-cooled, but owing to plastic quality is relatively light, easily raise up under airflow influence,
Thus make plastic grain be less useful for by screen cloth, therefore in the urgent need to developing the screening plant of a kind of invention, with satisfied reality
The needs used.
Utility model content
The purpose of this utility model is to provide one can lower the temperature to plastic grain, does not affect screening simultaneously,
And the plastic grain screening plant of screening efficiency can be improved.
For reaching above-mentioned purpose, base case of the present utility model is as follows:
Plastic grain screening plant includes support and feed hopper；Also include air main, screen cloth and be made up of non-woven fabrics
Collection pocket；Described air main is horizontal on support, and air main is fixing with support to be connected；One end of air main is feed end, main air
The pipe other end is end of selecting materials, and the sidewall of feed end offers charging aperture, and the end of feed end is provided with charging blower fan, feeds wind
The air outlet of machine connects with air main, and described feed hopper corresponds to charging aperture, and feed hopper is fixed on air main；Described screen cloth
It is fixed on and selects materials in end, and be fixed with discharge nozzle on the side wall of selecting materials of screen cloth both sides, and discharge nozzle connects with air main；Discharging
The end of pipe is fixed with discharging airduct, and discharging airduct forms three-port structure with discharge nozzle, and one end of discharging airduct is provided with discharging
Blower fan, described collection pocket is fixed on the other end of discharging airduct；Described charging blower fan and discharging blower fan all use ion blower.
The operation principle of this programme plastic grain screening plant is:
Starting charging blower fan and discharging blower fan, the plastic grain after then drying is poured in feed hopper, then plastic grain
The feed end of air main will be entered into by charging aperture, owing to plastic grain itself is relatively light, the air-flow that therefore charging blower fan is formed
Plastic grain will be made to suspend, and plastic grain will enter into end of selecting materials with air-flow；Along with the prolongation of air main, air-flow is at air main
The most also will gradually decay, therefore plastic grain will be gradually reduced under gravity, and different size of granule is pushed into
Distance is also different；Additionally different size of plastic grain can be screened by screen cloth further, i.e. larger particles is hindered by screen cloth
Gear, less granule then passes through screen cloth；Owing to the air-flow in air main is discharged merely by discharge nozzle, therefore air-flow will be moulding
Material granule is taken out of from air main, and the air-flow additionally formed in discharging airduct forms negative pressure in can making discharge nozzle, can further speed up
The discharge of plastic grain；When plastic grain is after discharging airduct is discharged, by entrance collection pocket, collection pocket is made up of non-woven fabrics,
Can discharge blasting air therein smoothly.
This programme produces and provides the benefit that:
This programme make use of plastic grain lighter weight, at interference in air flow low suspension, and the feature that can be promoted by air-flow, make
It passes through screen cloth, can be quickly completed the screening to plastic grain with this；In screening process, the air of flowing can be simultaneously to moulding
Material particle is lowered the temperature；Owing to plastics easily produce electrostatic during friction, and feed blower fan and discharging blower fan use from
Sub-blower fan, can effectively go to destatic, and then prevents plastic grain from mutually boning or adsorb on the sidewall or screen cloth of air main,
Impact is selected materials；In addition it directly can be collected after plastic grain is discharged by the structure of this programme, thus it is convenient to reduce operation
Transport.
Preferred version one: as the further optimization to base case, described screen cloth includes one-level screen cloth and two grades of screen clothes,
One-level screen cloth, two grades of screen clothes are arranged in order in described end of selecting materials, and one-level screen cloth is near feed end；One-level screen cloth, two grades of sieves
Online mesh is sequentially reduced, then can form three storehouses of selecting materials in the end of selecting materials of air main, can increase with this and to select materials
Classification, thus finer plastic grain is screened.
Preferred version two: as the further optimization to base case, described discharge nozzle is provided with outlet valve；Discharging is set
After valve, close outlet valve, then discharge nozzle will stop discharging, just can change collection pocket very easily.
Preferred version three: as the further optimization to base case, the diameter of described air main feed end is less than selecting materials
The diameter of end；When the diameter of feed end is less than the diameter of end of selecting materials, air-flow will disperse, then after entering, from feed end, end of selecting materials
Plastic grain also will scatter, and be conducive to selecting materials；And the diameter of feed end is less, air-flow velocity can be strengthened, plastics can be made
The speed of grain increases, and is conducive to it to pass through screen cloth.
Preferred version four: as the further optimization to base case, a diameter of discharging dust diameter of described discharge nozzle
50%；When the diameter of discharge nozzle is less, the ratio that in discharge nozzle, plastic grain mixes with air is more than plastics in discharging airduct
The ratio that granule mixes with air, therefore the air-flow velocity in discharge nozzle is relatively low, and in discharging airduct, the flow velocity of air-flow is higher, has
It is beneficial to increase the negative pressure in discharge nozzle so that the discharge of plastic grain is more smooth.
Preferred version five: as the further optimization to base case, be provided with regulation valve at described charging aperture；Regulation valve
Plastic grain can be regulated and enter the flow in air main, thus be conducive to controlling plastic grain and the mixing of air in air main
Ratio, in order to control to select materials.
