Embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Description, embodiment described herein is only the part of the embodiment of the present invention, and not all embodiment.Based on this hair Embodiment in bright, the every other embodiment that those of ordinary skill in the art are obtained under the premise of no creative work, Belong to the scope of the present invention.
As shown in figure 1, the pneumatic breaking sifter of the present invention includes casing 1, cylinder 7, air cylinder support 9, the and of dental lamina 11 Sieving plate 12.
The upper and lower of casing 1 opens up lime-ash inlet and outlet respectively, and sieving plate 12 is horizontally set in casing 1, and two cylinders 7 are logical Cross air cylinder support 9 and be oppositely arranged installation installed in the relative both sides of the external position of casing 1, two pieces of dental laminas 11 for being used for crashing steel (iron) slag block In casing 1, on sieving plate 12, each dental lamina 11 is connected by the stroke shaft 5 through the side wall of casing 1 and a cylinder 7 Connect, work is driven by cylinder, the lime-ash outlet port of the lower section of casing 1 is provided with the deflector 16 being obliquely installed.
The position of stroke shaft 5 through casing 1 is provided with seal disc 2, and the outside of seal disc 2 is provided with packing sleeve 3, packing set Cylinder 3 is used to support stroke shaft 5, and closure 4 is additionally provided with outside packing sleeve 3.Stroke shaft 5 and the link position of dental lamina 11 and stroke shaft 5 are provided with cloth bag sleeve 10 with the link position of seal disc 2.
After ash and slagging enter chamber from charging aperture, fine ash and slagging will be sized plate 12 and separate, and sieving plate is used 12Mn plates are process, and intensity is high, can prop up the impulsive force of grey block and indeformable.Fine ash is entered to put in storage by sieving plate from discharging opening Pump, slagging are then stayed on sieving plate 12, and now, cylinder 7 drives the synchronous extruding of dental lamina 11, and slagging is crushed.After being pressed into place, OK Cheng Kaiguan sends signal, and one travel switch of every cylinder, cylinder is withdrawn, into next working cycles.
Further, in addition to PLC control system, the extreme position that each cylinder 7 moves are provided with travel switch, work as generation When cylinder 7 is failure to actuate or can not acted in place, signal can be timely fed back to PLC control system.
Further, stroke shaft 5 is connected with cylinder 7 by spacing shaft joint 6, and spacing shaft joint 6 and cylinder are threaded connection, Spacing shaft joint 6 and stroke shaft 5 are pin connection.The gap on the screened plate 12 of slagging after broken is fallen on deflector 16, from Discharging opening enters the pump that puts in storage, and participates in conveying.
Further, the screening board mount 13 of two triangles is installed, sieving plate 12 is by sieving board mount 13 in casing 1 Top is exported installed in the lime-ash of casing 1, two deflectors 16 are separately mounted on two screening board mounts 13.Cylinder 7 passes through gas Cylinder foot stool 8 is fixed on air cylinder support 9.
Cylinder and dental lamina are connected with spacing shaft joint 6, wherein spacing shaft joint and cylinder are threaded connection, and dental lamina is pin Connection.
Further, casing 1 is not provided with offering manhole 15 in a side wall of cylinder 7.
In control aspect, cylinder switchs equipped with line position, and signal enters in Geldart-D particle PLC control system, may participate in whole In individual induction system.Meanwhile line position monitoring switch dental lamina position, when such as generation dental lamina is failure to actuate or can not acted in place, all Fault alarm can be sent, operation is all controlled by PLC, while solving lime-ash, realizes full-automatic work.
In control aspect, cylinder is furnished with travel switch, and signal is delivered in Geldart-D particle control system, travel switch monitoring tooth Board position, when generation dental lamina 11 is failure to actuate or can not acted in place, it can all send fault alarm.Dental lamina 11 run all by Programme-control, realize full-automatic work.
The course of work of the present invention is:
A) first the material for entering pneumatic breaking sifter is sieved, separates its thickness material;
B) the screened plate 12 of material for being not up to Geldart-D particle granulometry separates, and sieving plate works independently, and is served only for sieving Point, it would be desirable to broken material is stayed on sieving plate.Two dental laminas 11 work asynchronously, it would be desirable to broken material attrition crushing.
C) all materials into the lower section of deflector 16 of slagging after crushing are pooled to sifter outlet;
D) material for reaching Geldart-D particle granulometry is directly entered storehouse pump;
It is that system is safe and reliable using the advantages of this equipment, operation is convenient, and caused plugging can not be conveyed by solving lime-ash Situation, at the same without specially be lime-ash the problem of arrange work personnel exclude lime-ash manually the problem of.
Above example is merely to illustrate technical scheme rather than its limitations, although with reference to above-described embodiment pair The present invention is described in detail, and those of ordinary skill in the art can still be carried out to specific embodiments of the present invention Modification or equivalent substitution, and these are without departing from any modification of spirit and scope of the invention or equivalent substitution, it exists Within the claims of the present invention.
