The device is arranged at a discharging hole of a plastic pulverizer, finishes the crushing and separating procedures of plastics by one step and blows the dust into the dust-collecting bag to prevent the dust from flying, and the production of crushing and recycling plastics reaches the aims of no dust escape, working environment purification, procedure simplification, labor cost reduction and production efficiency improvement.
Description
Technical field
The present invention relates to a kind of separator, specifically be meant and utilize a kind of negative-pressure air power plastic grain that wind-force comes the plastic grain in the plastic grain dust mixture and dust separation and the separator of dust.
Background technology
During the plastics recovery regeneration, need be with the granulation again after pulverizing, sorting, cleaning, oven dry of waste or used plastics goods; Prior art adopts plastic crusher pulverizing waste plastics usually; Plastic crusher can produce a large amount of dust when the pulverizing waste plastics; Dust is to be made up of the earth dirt and the tiny plastic flakes that adhere on the waste or used plastics, and these dust parts are mixed in the plastic grain, and the air-flow that a part produces along with pulverizer fills the air everywhere and flies upward; Make working environment very abominable, harm operative employee's health; Simultaneously, collected pulverizing material also must carry out sorting once more, and useless and harmful dust and useful plastic grain are separated; Therefore, prior art pulverizing waste plastics exist dust harzard big, the problems and shortcomings that sorting recruitment cost is high once more, production efficiency is low.
Summary of the invention
Problems and shortcomings to above-mentioned prior art existence; The present invention adopts the device of being made up of separator, air-introduced machine, dust bag, utilizes the technical scheme of negative-pressure air power dust suction separating plastic particle and dust, and the separator of a kind of negative-pressure air power plastic grain and dust is provided; Be intended to this device is arranged on the discharging opening place of plastic crusher; The pulverizing of disposable completion plastics and sorting operation are blown into dust in the dust bag, stop dust from flying; Make the production of pulverizing the recovery plastics reach no dust and leak, purify working environment, the purpose of simplify working process, reduce the recruitment cost, enhancing productivity.
The objective of the invention is to realize like this: the separator of a kind of negative-pressure air power plastic grain and dust; Comprise separator, air-introduced machine, dust bag, wherein: described separator is made up of housing, last guide plate, lower guide plate, batch mixing import, particle outlet, dust air channel; Wherein, housing is that corrosion resistant plate is processed, and communicates up and down, and the rectangular funnel shape approaches ancient piece of jade, round, flat and with a hole in its centre casing; The upper edge hole of housing is the batch mixing import of overlooking to rectangle, and following bead is that for looking up rectangle, side-looking are the particle outlet of slope closing in from right to left; In the housing inner chamber: to nearly lumen centers, be welded with a last guide plate that becomes the corrosion resistant plate formation on 40 ° of slopes downwards with upper edge hole from upper left bead; To crossing lumen centers, be provided with a lower guide plate that becomes the corrosion resistant plate formation on 53 ° of slopes downwards with upper edge hole from upper right bead, the bottom of lower guide plate is arranged in 2/3 downward place of housing inner chamber; Space intersection place between last guide plate, the lower guide plate leaves Lou material narrow slit; The dust air channel is to become 10 ° to have a down dip to the right with horizontal line, and left end is that rectangle is dehisced, and right-hand member is the circular thin ancient piece of jade, round, flat and with a hole in its centre stainless steel pipes that closes up; The upper edge hole that dust air channel left end rectangle is dehisced is welded in downward 2/5 place of the upper right outer wall of lower guide plate, and that dust air channel left end rectangle is dehisced is forward and backward, bead is welded on the upper right outer wall of housing and communicates with the housing inner chamber down; The bottom right wall of the housing that the following bead of dehiscing with dust air channel left end rectangle intersects is the slope board that left closes up parallel with lower guide plate; Lower guide plate extends down into the part in the housing inner chamber, in the housing inner chamber of left is dehisced in the dust air channel, forms the stifled screen wall facing the gate of a house of isolating; The circle of dust air channel right-hand member closes up and links to each other with the air inlet of said air-introduced machine; Described air-introduced machine is the speed governing centrifugal blower, and the air inlet of air-introduced machine closes up with the circle of the dust air channel right-hand member of said separator and links to each other, and the air outlet of air-introduced machine links to each other with the import of said dust bag; Described dust bag is ventilative cloth bag, and the import of left end links to each other with the air outlet of said air-introduced machine, and the outlet of left end is tightened sealing by band.
Operation principle
During application, separator is placed the below of pulverizer discharging opening, the check apron of anti-" material spring " is set between the batch mixing import of pulverizer discharging opening and separator, below the particle outlet of separator, shelve the particle collector;
Pulverizer and air-introduced machine are started shooting simultaneously, and the batch mixing import that the batch mixing of pulverized plastic grain and dust gets into separator through the pulverizer discharging opening falls into the following housing inner chamber of lower guide plate through last guide plate, lower guide plate; At this moment, because the effect of air-introduced machine forms negative pressure in the housing inner chamber, extraneous air is downward by the batch mixing import of separator, and particle outlet upwards gets into the housing inner chamber, in the following housing inner chamber of lower guide plate, crosses and forms the whirlwind eddy current; Air-flow is from bottom to top walked around the isolation screen wall facing the gate of a house through the bottom of lower guide plate, through dust air channel, air-introduced machine, dust bag, enters atmosphere; Above-mentioned plastic grain and the dust batch mixing that falls into the following housing inner chamber of lower guide plate separates under the effect of whirlwind eddy current; Heavier plastic grain is to falling into the particle collector that places the particle outlet below; Lighter dust is wrapped up in by the whirlwind eddy current and is taken, and blows in the dust bag with air-flow, and air enters atmosphere from the cloth crack of dust bag; Dust is stayed in the dust bag, focuses on afterwards; Because the whirlwind eddy current makes plastic grain bump each other, and is therefore, clean attached to the also separated removing of the dust on the particle; Because suction function in separation process, does not have dust and escapes contaminated environment.
Useful effect
The present technique scheme has been saved special sorting operation; For the recovery of waste or used plastics, can directly get into matting; For the recovery of Shooting Technique stub bar, save cleaning, baking operation, can directly get into granulating working procedure, perhaps directly return and mix an injection mo(u)lding.
Above-mentioned; The present invention adopts the device of being made up of separator, air-introduced machine, dust bag, utilizes the technical scheme of negative-pressure air power dust suction separating plastic particle and dust, a kind of negative-pressure air power plastic grain that is provided and the separator of dust; The dust harzard that has overcome the prior art existence is big; The problems and shortcomings that sorting recruitment cost is high once more, production efficiency is low are through being arranged on this device the discharging opening place of plastic crusher, the pulverizing of disposable completion plastics and sorting operation; Dust is blown in the dust bag; Stop dust from flying, make the production of pulverizing the recovery plastics reach no dust and escape, purify working environment, the purpose of simplify working process, reduce the recruitment cost, enhancing productivity.
