Description
Technical field
The utility model relates to a kind of metal spraying device, relates in particular to a kind of powder feeder.
Background technology
The nanometer technology of supersonic speed micron bombardment metal material surface is to adopt high pressure compressed gas to drive ultra-fine hard particles, forms nanocrystalline with ultrasonic speed bombardment metal material surface.Nanocrystalline homogeneity for the formation of security deposit's metal surface, requirement is carried out even processing to the surface, and its gordian technique is to carry out uniform hyperchannel powder feeding, and the powder of being carried is a ultrafine powder, many powder road powder feeder during the device that adopts, and be that the high pressure carrier gas formula is carried.
Powder feeder is to be used to store powder, carries a kind of device of powder simultaneously to the powder mouth according to certain processing requirement orientation.According to the characteristic and the requirement of carrying powder, powder feeder mainly contains: based on the atomization type powder feeder of gas pressure difference principle powder feeding; Fine powder powder feeder based on the powder feeding of porose disc punching press principle; Scraper-type powder feeder based on the powder feeding of gasdynamics principle; Spiral powder feeder based on the powder feeding of mechanics of machinery principle; Dead-weight powder feeder based on the principle powder feeding of powder deadweight; Based on the drum type powder feeder that rotates the powder feeding of powder wheel principle; Beads excitation oscillatory type powder feeder based on the powder feeding of electric and magnetic oscillation mechanics principle; Based on the grinding rotating needle type powder feeder that rotates broken principle powder feeding; And, based on rotating the brush powder feeder of rotation that grinds the principle powder feeding.Yet above-mentioned these powder feeders all are to design at some specific powder, and its ubiquitous defective is: based on the special property of ultrafine powder, can not delivery diameter less than 1 micron ultrafine powder.Wherein:
The dead-weight powder feeder is the simplest powder feeder of structure, and its deadweight by powder makes powder fall, and by means of the negative pressure that the powder feeding air-flow causes in pipeline, makes powder flow into powder conveying pipe, and by powder conveying pipe powder is finally delivered to spray gun.This automatic powder feeding system requires powder to have good sphere and mobile, because the adjusting of powder sending quantity mainly is to realize by the aperture of changing powder leakage hole, so its powder sending quantity is regulated inconvenience, variable range is very narrow, the powder feeding process is also discontinuous simultaneously.
The scraper-type powder feeder is that powder is flow on the powder dish through powder leakage hole by powder storage hopper, piles a conical powder heap with nature stocking angle, and when the powder dish rotates a week, then piling a circle radius on the powder dish is the powder of R, and its cross section is similar to isosceles trapezoid.The power that the maintains static scraper plate that is positioned on the powder dish constantly scrapes the powder of piling up on the powder dish into funnel, by the powder feeding air-flow it is delivered to spray gun again.
Spiral powder feeder is made up of screw rod, hopper, powder bucket, mixing tank and vibrator.Screw rod is rotated by electric motor driving, and the drive powder moves along the spiral slot of powder bucket inwall, and is transported in the mixing tank, and the current-carrying gas in the mixing tank transfers out powder with the fluidic form.The powder sending quantity of this powder feeder is directly proportional with the speed of rotation of screw rod, regulates the rotating speed of control screw rotating motor, just can accurately control powder sending quantity, but this powder feeder is not suitable for different mixed powder of proportion and the different powder of granularity, and stifled powder easily takes place.
The powder of atomization type powder feeder sprays at a high speed from the very little nozzle of diameter, the local depression that is produced by it sucks in the flour extraction pipe powder, have an equilibration tube to stretch into powder bucket top on flour extraction pipe, its effect is to keep in the tube cell corresponding pressure being arranged, thereby is beneficial to falling of powder.The powder sending quantity of this powder feeder is to realize by distance between inlet mouth and the flour extraction pipe and gas flow.This class powder feeder is applicable to the powder that proportion is lighter, but is not suitable for the different powder mix of proportion, and the tolerance of powder feeding simultaneously can not be regulated.
The drum type powder feeder is got powder by equally distributed a plurality of sulculuses on the drum circumference, and powder in small opening flow to the drum sulculus, when drum rotates, flows out the powder in the sulculus by powder storage hopper successively from the powder mouth.
A sending disk of powder is arranged at the starch storing cylinder of fine B5 type powder feeder bottom, and electric hammer is pressed into aperture to powder automatically successively synchronously, and when the aperture that fills up powder when porose disc went to powder feeding delivery port position, air-flow was gone out the powder in the aperture, and powder flow to spray gun through pipeline.This powder feeder can not satisfy the spraying that powder sending quantity is big, uniformity requirement is higher.
Summary of the invention
Goal of the invention of the present utility model provides a kind of many powder road powder feeder, this powder feeder is used for carrying ultrafine powder under hyperbaric environment, and it is adapted to the high pressure of 15MPa, and the powder operational throughput can be regulated, the powder output speed is even, can satisfy the demand of even making Nano surface of metal material.
According to the foregoing invention purpose, a kind of many powder road powder feeder is proposed, comprise pollen chamber, store powder in the described pollen chamber, this many powder road powder feeder also comprises in addition:
One sealed air chamber is located at the top of described pollen chamber, and passes through one and be with the tracheae that opens and closes valve to be communicated with described pollen chamber;
One motor is located in the described sealed air chamber;
The circle of the one hollow powder dish that falls is located at the bottom of pollen chamber, and the inner edge of the described powder dish that falls is interval with some crenation projections, on described each crenation projection all correspondence be provided with a gas hole; Described each gas hole evenly is provided with along a circumference, and the part of the described powder dish hollow that falls is the powder groove that falls;
One with the concentric minute powder dish of powder dish that fall, fit in the lower surface setting of the described powder dish that falls, the powder dish also was connected with motor by a transmission shaft in described minute, some dress powder hole closely is arranged in the position of corresponding described circumference on the branch powder dish, and each is adorned the powder hole and also realizes conducting with each gas hole by the rotation that divides the powder dish;
One with the concentric base of powder dish that falls, fit in the lower surface setting of described minute powder dish, the position of corresponding gas hole is provided with some flour openings on the described base, described each flour opening and the corresponding connection of some powder conveying pipe conducting.
