Description

Steel alloy boat cleaning plant
Technical field
The utility model belongs to the cleaning plant that a kind of powder metallurgy is prepared container, specifically a kind of steel alloy boat cleaning plant.
Background technology
Steel alloy boat is conventionally to use and produce container in powder metallurgy preparation, its operating temperature is at 1000 ℃ to 1400 ℃, this boat material generally includes elemental nickel, tungsten, iron, chromium, two or more compositions in titanium, under condition of work, boat surface easily forms the nickel of product and boat, the adhesion of iron etc., the metal adhesive thing forming under this high temperature can firmly remain in boat surface, cause product cannot unload to the greatest extent or the increase of product impurity content, product quality is caused to adverse influence, and boat self crystal grain when hot operation is used can be grown up, form thick crystal grain, dendrite arm, boat mechanical strength declines, cause boat cracking, distortion, damage and scrap.
Process at present boat surface bonding material and conventionally adopt artificial treatment and blasting treatment.Use instrument knocks boat, not only larger to the being damaged deformation of boat, and labour intensity is high, inefficiency; Blasting treatment adopts the quartz sand of high velocity jet to wash away boat surface, the sticky object on flake-off surface, but quartz sand proportion is little, intensity is low, removing to harder sticky object on high temperature boat is very difficult, and product powder and the quartz sand cleared up mixes, be not easy to the recycling of product powder.
Utility model content
The purpose of this utility model is to provide a kind of steel alloy boat cleaning plant that can thoroughly remove steel alloy boat surface sticky object.
The utility model comprises moving runner, lower moving runner, belt elevator, and belt elevator is provided with shovel hopper; Funnel is arranged on a side relative with upper moving runner; One end of tube connector is connected with the lower end of funnel, and the other end is connected with impeller centre bore; Impeller is arranged on the top of crawler belt; In impeller, be provided with blade; Filter plate is arranged on the below of crawler belt, is placed on warehouse; Feeding screw is connected with warehouse bottom; Lower moving runner bottom is positioned at discharging opening one side of warehouse, also comprises the drive unit of moving runner, impeller, crawler belt, feeding screw.
The utility model in use, is placed on the spherolite alloy of cleaning boat in warehouse, with the belt elevator that shovels hopper, under the drive of moving runner, after the spherolite alloy shovel of warehouse discharging opening is carried, rises to eminence.Spherolite alloy is scattered on the surface of impeller blade after being rolled into impeller centre bore by tube connector, blade is under the impeller of High Rotation Speed drives, the spherolite alloy directive of dishing out is at a high speed placed on to the boat on crawler belt, boat is under the impact of a large amount of high speed spherolite alloys, and the sticky object on top layer peels off rapidly.Sticky object falls into by crawler belt gap on the filter plate of bottom, the sticky object that granularity is less and spherolite alloy fall into warehouse through filter plate, feeding screw is deposited in discharging opening one side by the spherolite alloy in warehouse and the less sticky object of granularity, again be raised belt shovel and carry utilization, thicker graininess sticky object is tackled by filter plate, in order to avoid damage blade when with blade high-speed impact.Sticky object on steel alloy boat repeatedly impacts through spherolite alloy, cleaned work.
Further improvement is, pile-up welding hard alloy layer or cast tungsten carbide layer on described blade, and preferably overlay cladding thickness is 2~5mm.Because spherolite alloy rigidity is higher, in a large amount of spherolite alloy high-speed strikings, very large to the wearing and tearing of blade, the high-hardness wear-resisting bead layer on blade can improve the wearability of blade, and is guaranteed the service life of blade.
Further improve is that in warehouse, the middle spherolite alloy of placing is cemented carbide pellet alloy.The hardness of cemented carbide pellet alloy is higher, can improve boat cleaning effect.
Further improve is that the material of spherolite alloy is preferably consistent with the product material that boat is produced.Because the composition of spherolite alloy own is consistent with product powder, therefore the spherolite alloy of drawing small and the product powder of clearing up on boat can together with reclaim and do hard alloy material and use.
Further improving is that described spherolite alloy granularity is 0.5~0.8mm.Because spherolite alloy granularity is less, the sticky object of impact-spalling boat surface under high-speed projectile, can increase the contact-making surface of spherolite alloy and boat, is not easy to produce cleaning dead angle, has improved cleaning efficiency.Particularly especially cemented carbide pellet alloy of the spherolite alloy of this granularity, impacting boat material when surface can refinement boat crystal grain, make the strengthening of the boat surface mechanical property of materials, extended the service life of boat, the spherolite alloy of simultaneously a large amount of reduced sizes impacts boat surface, the micro-hole staying is tiny and intensive, makes the fineness of boat surface better.
Further improve is that described crawler belt working face comprises smooth section and vertical section.It is upper that boat for clearance is placed on smooth section of impeller below, and boat is along with caterpillar drive, is transitioned into vertical section from smooth section, under Action of Gravity Field, falls, overturns, and go round and begin again, thereby make the each surface of boat all can obtain washing away of spherolite alloy.Cleaning effect is very good.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
1, boat is after cleaning, and the product powder of bonding is effectively removed, and has reduced the impact of sticky boat material on normal product, has improved product quality.
2, because the composition of spherolite alloy spherolite alloy of cleaning plant own is consistent with product powder, make the bond powders cleared up and product powder can together with recycle.
3, boat is after cleaning, and it is bright and clean that boat surface becomes, and avoided the being damaged deformation of artificial treatment to boat, extended the service life of boat.
