Abstract
The utility model discloses a smashing device for recycling waste PCBs and aims to solve the problem that the recycling rate and the smashing rate of the waste PCBs are low. The smashing device for recycling the waste PCBs consists of a sorting platform (1) with a conveying belt, an extruding machine (4) and a ball mill (6), the sorting platform (1) with the conveying belt is connected with a feed hopper (3) of the extruding machine (4) through a chute (2), and a discharge port of the extruding machine (4) is connected with a feed port of the ball mill (6) through a belt conveyor (5). Therefore, the smashing device for recycling the waste PCBs has the advantage of being high in smashing rate.
Description
Technical field
The utility model relates to a kind of reducing mechanism, relates in particular to a kind of reducing mechanism for the waste printed circuit board recovery.
Background technology
Chinese patent CN1229008A discloses a kind of like this method that is reclaimed valuable substance by printed circuit board (PCB), comprise the following steps: one. the waste printed circuit board of given shape and size does not drop into a high speed changes in the cutting machine, this changes cutting machine inside at a high speed and is provided with most fixed cutting tool and rotary cutters made from the wolfram steel material, each fixed cutting tool is arranged on around this rotary cutter, but this circuit board moment is shredded continuously and form particle, the multi-level oscillatory type strainer filtering that cutting machine outlet at bottom place arranges is changeed in this particle utilization at a high speed; Two. this particle is delivered in the high speed disintegrator by a conveyer belt, and this high speed disintegrator inside is provided with the knife plate that turns to together with this rotary cutter, makes this particle form the thinner pulverizing grain sheet of particle; Three. should pulverize a grain sheet and deliver to an impact crusher inside and thump, and make its internal structure destroyed, and form thin flat bar; Four. should deliver in the efflorescence machine by thin flat bar, the rolling wheels that this efflorescence machine inside comprises most group horizontally sets and vertically arranges, and form the powder sheet material after making this thin flat bar via this rolling wheels roll extrusion efflorescence; Five. this powder sheet material is added water and insert in the flour mill and wear into fine-powdered, utilize current and centrifugal force to derive and grind the powder of finishing; Six. above-mentioned current and powder are imported in the tank, on nonmetallic substance in this powder can be bubbled through the water column, utilize centrifugal dehydration after will this nonmetallic substance collecting, the recycling drying machine is dried make an uproar after, resin in this nonmetallic substance can be vaporized, and all the other then are the glass fibre of recyclable utilization; Seven. after the metal object value that will be sunken to this bottom of gullet is concentrated, via an electric smelting furnace heating, isolate different metal species according to the height of fusing point, cool off through normal temperature again.Because this method has adopted and changeed cutting machine, high speed disintegrator, impact crusher, efflorescence machine and flour mill at a high speed, thereby has increased operation and cost, because the fine powder after flour mill grinds is thicker, its rate of recovery only can reach 90% again.
Summary of the invention
The purpose of this utility model provides and a kind ofly can reduce operation, equipment and input cost, can improve the reducing mechanism that waste printed circuit board reclaims that is used for of the rate of recovery again.
For achieving the above object, the retracting device of a kind of waste printed circuit board of the utility model, formed by the go-no-go platform, extruder and the ball mill that have conveyer belt, the go-no-go platform that has conveyer belt is connected with the extruder feed hopper by hopper, and the extruder discharging opening is connected with the ball mill charging aperture by belt conveyor.
Described extruder is made up of motor, gearbox, support, feed hopper, helical axis and press for extracting juice thorax, motor and gearbox are arranged on the support, pressing thorax one end and gearbox connects and composes cantilever-shaped, helical axis places and presses in the thorax, helical axis one end is connected with output shaft of gear-box, and feed hopper places to press on the thorax and with press for extracting juice thorax inner chamber and communicates.
Have the groove of being convenient to material toggling together at described press for extracting juice thorax, the external world is communicated with press for extracting juice thorax inner chamber.
The root diameter of close gearbox one end of described helical axis is less than the root diameter of helical axis near discharging opening one end.
After adopting this structure, because extruder is squeezed into waste printed circuit board the waste printed circuit board of various not given shapes, steel ball in ball mill and forging roll grinding again, make waste printed circuit board become 80～100 purpose powder, greatly be conducive to decomposition and the extraction of back operation, show that through actual measurement the rate of recovery reaches 100%, operation and cost can be reduced thereby reach, the purpose of the rate of recovery can be improved again.
