Bullet circularly purifying system: bullet circularly purifying system is by conveying worm 5, bucket elevator 11, and heavy curtain sorter 8, storage ball bucket 17, the ball pipe 19 that falls, pneumatic ball valve 14 is formed.
Auger conveyor 5 is commonly called as auger, and its effect is to compile from shot blast room cleaning 6 shots that fall, and it is transported to elevator 11.In auger conveyor 5, motor 20 and reductor 21 thereof are installed on the support, and the output chain gear of reductor 21 utilizes chain 22 to be connected with the sprocket wheel that is installed on screw rod 23 ends, and screw rod 23 is installed on the support.Auger conveyor 5 is driven screw rod 23 and is rotated by motor 20, reductor 21, chain 22.
The shot that elevator 11 is sent conveying worm 5 here promotes and unloads to heavy curtain sorter 8, elevator 11 comprises elevator housing 47 and is positioned at the driving belt 46 of elevator housing 47, this belt 46 is surrounded on the squirrel-cage cylinder 40 that is installed in elevator housing two ends about in the of 47, some lifting hoppers 45 that can hold material are arranged on belt 46, on elevator housing 47, be useful on the motor 43 and the reductor 42 thereof that drive squirrel-cage cylinder 40 and chain 44 runnings; On elevator housing 47, also be provided with the access door 41 that is used to keep in repair, change elevator bucket 45 or belt 44.When can guaranteeing work, carry on squirrel-cage cylinder 40 adhesive tape non-slip.So both improve the frictional force between adhesive tape and belt wheel, avoided the skidding of old-fashioned smooth bark belt wheel, reduced the pretightning force of belt again, prolonged the service life of adhesive tape.Cause pill to stop up for preventing that the elevator belt wheel from skidding, also be provided with automatic detection, stopping alarm device.
The effect of heavy curtain sorter 8 is thick foreign material to be sieved exclusive, and shot is distributed to two ball pipes that fall equably, guarantees each impeller head 10 operate as normal, by the air curtain air draught dust is sucked deduster in minute ball.The operation principle of heavy curtain sorter 8 is: the heavy curtain sorter 8 that shot flows into from elevator 11, shot, burning skin fragment, broken pill that while dedusting fan 2 will flow in the curtain effectively separate with dust, tiny pill, dust flow out from dust outlet 18, and shot enters ball feed bin 17 and circulates.The bottom of ball feed bin 17 is provided with the distribution steel pipe 19 of two shots, and cylinder ball valve 14 respectively is equipped with in the distributing pipe lower end, by the switching of cylinder control shot; The control of shot flow size can realize leading to by regulating a cylinder location change unlatching mouthful size, flows into two impeller heads 10 at last.
Free-wheeling system 9: driven by motor 58, cycloidal planetary gear speed reducer 57, drive sprocket wheel 55 by chain 56 and make the suspender rotation, rotational velocity is continuous adjustable frequency control between 2～6r/min.The disengagement of free-wheeling system is pneumatic with the employing of closing.In suspender, the fixedly connected axle sleeve 51 in the upper end of suspension rod 50, the fixedly connected sprocket wheel 52 in the upper end of axle sleeve 51, bearing is housed in the inside of axle sleeve 51 to be connected with peg 53, there is roller 54 upper end of peg 53, and utilizing this roller 54 to hang on the guide rail, the sealing strip 49 that is arranged on the support 61 is passed in the lower end of suspension rod 50, at the bottom of suspension rod 50 connecting shackle 48.Motor 58 and reductor 57 are installed on support 61 simultaneously, are utilized sprocket wheel and chain 56 to be connected with sprocket wheel 55 on being installed on support at the output of reductor 57; Promote dolly by cylinder and is connected with sprocket wheel 52 on the peg 53 by chain, the drive workpiece rotates.
Dust pelletizing system: adopt expansion chamber 13, cyclone separator 4 and filter cartridge dust remover 3 multistage dedustings.The effect of expansion chamber 13 exempts to make the shot loss too much qualified shot separating and recovering.Cyclone separator 4 separates bigger particles such as broken shot in advance, to prolong filter cylinder service life.3 of filter cartridge dust removers are to filter trickle shape dust, make the gas discharging meet the final filtration of discharging standards.Laying dust on the barrel adopts pulse of compressed air recoil mode to remove, to guarantee the stable of SR and work.Dust emission concentration meets relevant national standard (GB1627-1966), and the deduster fan noise is low, long service life.
Electric control system in the electrical control cubicles 1 adopts programmable controller, comprises PLC, frequency converter etc.The rotating speed of impeller head 10 is realized stepless adjustable by frequency conversion.Free-wheeling system 9 is time rotational not, can report to the police and quit work.The design of control system, manufacturing meet the IEC international electrical engineering standard.
The tooth-face strengthening of gear mainly is by the distance of the ball blast initial velocity that improves shot and shortening impeller head 10 and workpiece, strengthens the ball blast hitting dynamics.But the raising of initial velocity can bring noise to increase, and the shortening of distance can influence the service life of protective plate; So the requirement that appropriate design selects initial velocity and distance to satisfy the gear reinforcement is a key point.
The present invention has following features:
1, owing to increase the impeller head diameter pulley, improved the rotating speed of impeller head impeller and adopting projectile casting technology at the beginning of Speed, thus the dynamics of shot striking work strengthened. The rotating speed of traditional impeller head impeller is 2500～2900 Rev/min, the initial velocity of shot impelling is 73～85 meter per seconds; The rotating speed of impeller head impeller of the present invention is 3500 rev/mins, The initial velocity of adopting projectile casting technology is 100 meter per seconds.
2, (when the ball blast amount was constant, surface of the work connect owing to shortened mounting distance between impeller head and workpiece Be subjected to the quantity of bullet and workpiece square being inversely proportional to the impeller head distance), strengthened hitting dynamics, thereby carried High cleaning effect. Traditional impeller head and the mounting distance between workpiece centre are 600～2000 millimeters; This Mounting distance between bright impeller head and workpiece centre is 350 millimeters.
3, productivity ratio is significantly improved, in the prior art, every station weight 〉=30kg that packs into, beat 〉=12 stations/hour; Among the present invention, every station weight 〉=80kg that packs into, beat 〉=15 stations/hour.
4, behind the ball blast, the flank of tooth quality of gear is guaranteed, in the prior art, and A Ermei test piece camber: 0.254-0.38mmA, minimum coverage rate: 〉=100%, surface, part residual stress tooth root position 〉=-100Ksi (〉=-689Mpa); In the present invention, A Ermei test piece camber: 0.35-0.52mmA, minimum coverage rate: 〉=150%, surface, part residual stress tooth root position 〉=-120Ksi (〉=-864MPa).
