Description
Technical field
This utility model belongs to field of laser cladding, relates to a kind of dust feeder, is specifically related to a kind of gravity and pneumatic double-hopper device.
Background technology
Laser melting coating remanufactures recovery technique as the surface of a kind of advanced person, refer to that place, with different adding material modes, a thin layer that selected coating material is allowed to matrix surface through laser irradiation on by cladding matrix surface melts simultaneously, and it is extremely low to form dilution factor after rapid solidification, dense structure, the face coat of metallurgical binding is become with matrix, significantly improve the wear-resisting of matrix surface, anti-corrosion, heat-resisting, antioxidation and the process of electrical characteristic, thus reach the purpose of surface modification or reparation, both the requirement to material surface particular characteristic had been met, save again substantial amounts of noble element.
In field of laser cladding, powder feeder is necessary component, and its function is in the molten bath that cladding alloy powder is delivered to laser facula and base material active region, is also used in the enforcement of the technique such as plasma cladding, thermal spraying simultaneously.
Existing powder feeder mainly has two big classes: gravity powder feeder and pneumatic powder feeder.
In gravity powder feeder, scraper-type gravity powder feeder is wide because of cheap, powder amount adjustable extent, controls the feature such as simple and is widely used.Gravity powder feeder by powder hopper, hold powder rotating disk, scraper plate, powder-receiving hopper etc. and form.Powder relies on self gravitation to flow to rotating disk from powder hopper, and motor drives rotating disk to rotate, and constantly delivers to powder be in close contact with rotating disk and be fixed at the scraper plate above rotating disk, and powder is constantly scraped to powder-receiving hopper by scraper plate, delivers to molten bath through powder feeding pipe.
This scraper-type gravity powder feeder has the disadvantage that:
1, mass flow discrepancy is even.Powder is transported at scraper plate through rotating disk, first piles up in scraper plate side, and after reaching to a certain degree, pile of grounds lamination starts to cave in, and the powder that at this moment part is caved in flows out rotating disk outer to be fallen in powder-receiving hopper.In the process, with powder size, powder flowbility and the change of piling height, causing falling into powder-receiving hopper and then delivering to the powder amount at molten bath uneven, cause laser cladding layer in uneven thickness when caving in, surface quality is poor.
2, powder accumulation at center of turntable.Powder feeding principle due to scraper plate powder feeder; powder cave at scraper plate powder falling time, substantial amounts of powder, towards center of turntable, can be piled up often in the middle of rotating disk in some flow of powder direction caved in inevitable; cause disc surfaces to block, also affect the uniformity of powder feeding simultaneously.
In pneumatic powder feeder, rotating disc type pneumatic powder feeder powder pushing precision is high, controls the feature such as simple and also has extensive application.Existing pneumatic powder feeder includes source of the gas, air shooter, housing cover, housing, powder bucket, rotating disk, starch sucking nozzle, flour extraction pipe and the motor driving rotating disk to rotate.On powder dish fluted, housing cover and housing one airtight cavity of composition, rotating disk, starch sucking nozzle are in closed cavity, and the outfan of motor is connected with rotating disk, during work, powder relies on self gravitation or gas pressure to fall into the groove of powder dish from powder bucket, driven by motor powder disc spins, when powder is delivered at starch sucking nozzle, under the effect of gas pressure, powder is pressed into flour extraction pipe through starch sucking nozzle, finally delivers to molten bath.
The pneumatic powder feeder of this rotating disc type has the disadvantage that:
1, disc surfaces powder not easy cleaning.Due to powder before being inhaled into flour extraction pipe during closed environment to be in, so the construction features of the pneumatic powder feeder of rotating disc type determines and needs often to clean powder feeder, it is necessary to take seal casinghousing apart.In the case of frequently changing powder, this removal efficiency is the lowest, and the sealing of housing can be impacted by being dismounted for multiple times.
2, powder particle shape is required.Powder is to time at starch sucking nozzle, under the effect of gas pressure, powder is pressed into flour extraction pipe through starch sucking nozzle, for spherical particle powder, under the effect of the pressure, mobility is preferable, rather than spherical particle powder is under gas pressure, there will be and be pressed into the amount of powder of flour extraction pipe and have instantaneous pulsation phenomenon, cause powder outlet quantity uneven.
