The specific embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
In Fig. 1, Fig. 2, comprise lower conveying worm 1, elevator 2, impeller head 3, blow ball system 4, steel band clamping and conveying device 5, shot blast room 6, steel band delivery device 7, ladder landing platform 8, ball material separator 9, upper conveying worm 10, storage bin hopper 11, slip ball system 12, dust pelletizing system 13 etc.
As shown in Figure 1 and Figure 2, the present invention is a kind of steel band passing shot blasting machine, shot blast room 6, the ball material circulatory system, dust pelletizing system 13, ladder landing platform 8 and electric-control system, consists of.
The ball material circulatory system comprises lower conveying worm 1, elevator 2, upper conveying worm 10, ball material separator 9 and storage bin hopper 11.Storage bin hopper 11 is positioned at the top of shot blast room 6; The top of storage bin hopper 11 is connected with conveying worm 10, and ball material separator 9 is installed in storage bin hopper 11; The bottom of shot blast room 6 is connected with lower conveying worm 1, and lower conveying worm 1 is connected with upper conveying worm 10 by elevator 2.
Shot blast room 6 is comprised of steel construction chamber body, impeller head 3, backplate and sealing device.Chamber body adopts shaped steel, sheet material rivet welding structure, rational in infrastructure, intensity is high, good rigidly; In the body of chamber, wear plate is housed, wear-resisting, shock-resistant, long service life, change simple and convenient; For preventing that bullet from flying out, in the body of chamber, be provided with labyrinth protector.
On the relative sidewall of shot blast room 6, the steel band clamping and conveying device 5 for delivery of steel band is installed, in shot blast room 6, be furnished with the steel band delivery device 7 of the formation ball blast station corresponding with steel band clamping and conveying device 5, on the shot blast room 6 of ball blast station top and below, mounted in pairs has the impeller head 3 that points to ball blast station, and impeller head 3 is connected with the discharging opening of storage bin hopper 11.
Impeller head 3 has four at least, along the throughput direction perpendicular to steel band, is arranged symmetrically with.Impeller head 3 tilts to install, angle between the impeller head 3 above ball blast station and the horizontal plane at ball blast station place is α, angle between the horizontal plane at the impeller head 3 below ball blast station and ball blast station place is β, impeller head 3 and be γ along the angle between the vertical plane of the throughput direction of steel band, angle meets respectively: 15 °≤α≤25 °, 33 °≤β≤43 °, 11 °≤γ≤21 °.Above-mentioned angle is preferably respectively: α=20 °, β=38 °, γ=16 °.Be positioned at the impeller head 3 of ball blast station below for left-handed, the impeller head 3 that is positioned at ball blast station top is dextrorotation.3 minutes upper and lower reasonable Arrangement of at least 4 impeller heads, can clear up the surface of workpiece from all angles.Impeller head 3 adopts and left-handedly combines with dextrorotation, can further improve impeller blasting effect.
Impeller head 3 adopts direct connection centrifugal high effective impeller head; Ejection velocity is 65-70m/s.Impeller head 3 is assembled by guard shield, ingress pipe, trim ring, impeller, blade, orienting cover, shot wheel, conjoint disk, seal disc, end plate, side plate, top board, motor and securing member.
Storage bin hopper 11 is fixed on ladder landing platform 8, and storage bin hopper 11 and ladder landing platform 8 adopt shaped steel, sheet material manufacture.Storage bin hopper 11 be positioned at ball material separator 9 below, store the ball material through separator 9 sortings.The convenient maintenance ball material separator 9 of ladder landing platform 8 and upper conveying worm 10.
Ball material separator 9 adopts high efficiency, large capacity ball material sorter, and rational in infrastructure, ball material separation performance is superior.
The pill that impeller head 3 is dished out is collected, is processed through the ball material circulatory system, continues for impeller head.The working method of the ball material circulatory system is: the bullet being scattered is delivered to bucket elevator 2 through the lower conveying worm 1 of shot blast room 6 bottoms, bucket elevator 2 is promoted to ball material and foreign material on the top of shot blast room 6, by upper conveying worm 10, be delivered to ball material separator 9, after ball material separator 9 is processed, dust is separated with good ball material with foreign material, good ball material enters storage bin hopper 11 and stores, and treats for impeller head 3.
The ball system 12 of slipping is installed on the discharging opening of storage bin hopper 11, slips ball system 12 for controlling the ball material flow that enters impeller head 3.The conveying of ball material between ball system 12 and impeller head 3 of slipping adopts wear-resisting wire rubber pipe.
On shot blast room 6, be also connected with and blow ball system 4, the air outlet that blows ball system 4 points to ball blast station, for purging the ball material remaining on steel band.
On shot blast room 6, be also connected with dust pelletizing system 13, dust pelletizing system 13 adopts filter drum type precipitator, mainly cleaning shaft, filter cartridge dust remover, blower fan, pulse mechanism, airduct etc., consists of.The dust of shot blast room 6 interior generations sucks deduster by centrifugal fan through ventilation shaft, first through settler by separated after larger particles sedimentation, the suspended dust of sedimentation is not drawn in dirt pocket, after filter cylinder filters, graininess dust is attracted on filter cylinder, is adsorbed on dust on filter cylinder and blows after hitting and fall into dust deposited case through the air pressure of pulse valve.
The filtering material of this deduster is selected import novel filtering material, is characterized in the super thin fiber of one deck submicron order to stick on general filtrate, arranges very closely between the fiber of adhesion layer, and its gap is only 1% of bottom fiber.Minimum sieve aperture can be blocked in most of submicron order grit the outer surface of filtrate, makes it must not enter bottom fiber inside.Therefore just form in the early stage the dust layer of good permeability, make it keep low-resistance, efficient.Because dust can not go deep into filtrate inside, therefore there is again low-resistance, be convenient to the feature of deashing, its filtering accuracy reaches 5 μ, and this feature is that common sack cleaner is incomparable.Therefore dust emission concentration is well below the relevant environmental requirement of country, and efficiency of dust collection is up to 99.5%, dust emission concentration≤50mg/m
3.
Airduct is exhausting from shot blast room 6, and due to not air-supply, shot blast room 6 is interior can form certain negative pressure, and dust can not escape.These dust pelletizing system 13 design air flows are large, and good dedusting effect remains that shot blast room 6 works under negative pressure, guarantees that in production process, working environment reaches related request.
The present invention has been carried out to the enough detailed description with certain particularity above.Under those of ordinary skill in field should be appreciated that, the description in embodiment is only exemplary, under the prerequisite that does not depart from true spirit of the present invention and scope, make change and all should belong to protection scope of the present invention.The present invention's scope required for protection is to be limited by described claims, rather than the foregoing description in embodiment limits.
