Specific implementation mode
The powder feeder with powder functions/drying is further described below in conjunction with the accompanying drawings.
This powder feeder with powder functions/drying, inert gas manufacture device 5 gas outlet by pipeline respectively with storage
The air inlet of the air inlet of powder drum 1, the air inlet of powder feeder 7 and powder feeding transmission device 6 connects, and powder feeding transmission device 6 is turntable
Formula powder feeding transmission device or scraper-type powder feeding transmission device or drum type powder feeding transmission device, the meal outlet of powder feeder 7 pass through pipe
Road is connect with the powder inlet of the powder inlet of powder transmission device and storage tube 1 respectively, meal outlet and the powder feeding transmission device of storage tube 1
6 powder inlet connection, storage tube 1 are equipped with heater 3, and heater 3 is contact conduction heating, or is microwave heating, or
Person heats for light radiation, and in order to measure the temperature of powder in storage tube bucket, temperature sensor is equipped in storage tube 1.Storage tube 1
Top is equipped with end cap 2, and storage tube 1 is internally provided with blender 4, and blender 4 is driven by stirring motor, and stirring motor is arranged in end cap
In 2, stirring motor is integrated with the setting of end cap 2.
According to the area of section of storage tube 1 and height installation heater 3, heater 3 be mounted on storage tube 1 madial wall or
On lateral wall or end cap 2.Meanwhile blender 4 is propeller mixer or turbine agitator or anchor agitator, it is corresponding to stir
The outside that motor is mounted on storage tube 1 is mixed, or mounted on 1 inside of storage tube, or mounted on the bottom of storage tube 1, or installation
On end cap 2.
Stirring motor is controlled by stirring motor control system, and heater 3 is controlled by 3 control system of heater, or
Stirring motor and heater 3 are controlled by the powder feeding control device of powder feeder 7.
As shown in Figure 1.Using first dried powder before powder feeder 7, stirring motor and 3 power supply of heater are opened.Stirring motor
4 rotating speed of blender can be controlled, heater 3 can control the variation of temperature by temperature sensor.After powder dries moisture,
Closing heater 3 and stirring motor power supply (if it is the powder that mobility is poor, then can individually open stirring motor auxiliary powder
The later and decadent stage of a school of thought is dynamic).Open the power supply of inert gas manufacture device 5 and powder feeder 7.Inert gas manufacture device 5 produce after inert gas with
It air-channel system and is respectively transmitted to storage tube 1 and powder feeding transmission device 6.Air pressure height can be controlled by powder feeding control device.
Powder falls into powder feeding transmission device 6 due to the promotion of its own gravity and air pressure in storage tube 1.
Stirring motor and end cap 2 are combined with each other, and can be got off with integral demounting.Powder is poured into toward storage tube 1, needs to hold
Lid 2 is removed together with stirring motor.After pouring into powder, 3 power supply of stirring motor power supply and heater is plugged.Stirring motor with give

The temperature of device 3.
The powder (such as ceramic powders) that stirring motor can make mobility poor uniformly flows.It is covered in storage tube 1 week
The calandria enclosed can coordinate stirring motor fully to dry moist powder.Because being full of inert gas in storage tube 1, dry
It will not be aoxidized when dry.Because storage tube 1 and heater 3 have fitted together, during avoiding transfer of powders, caused by it is secondary
Oxidation.Because being full of inert gas in storage tube 1, the possibility of oxide heat explosion is completely eliminated, need not be bought true
Empty thermostatic drying chamber, saves cost.By the conveying powder funnel of 1 top of storage tube, powder can be endlessly conveyed,
It solves the problems, such as that 1 capacity of storage tube is limited, improves efficiency.Because being only transformed in traditional storage tube 1, save dry
The floor space of dry case.
After drying device is compounded in the storage tube 1 of traditional powder feeder, solve because humidity is for powder flowbility
It influences；Blender 4 can be accelerated to dry the speed of powder, and the poor powder of mobility such as ceramic powders can also be risen
To the effect of promotion, in addition select suitable blender 4 that can uniformly mix different powder.Because being full of in storage tube 1
Inert gas, it is possible to heat oxidizable powder.Drying device, which is compounded in the storage tube 1 of traditional powder feeder, to be improved
The precision and efficiency of cladding.Powder with certain heat is in transmission process to the moisture content heating adhered on pipeline inner wall and band
It walks, plays the role of clearing up pipeline moisture content.
For traditional powder feeder because humid environment caused by moisture absorption caking, powder flowbility is poor the problems such as, tradition is sent
The storage tube 1 of powder device carries out upgrading.Calandria is covered around storage tube 1, and increases stirring motor above it, will be changed
The storage tube 1 made replaces the storage tube 1 of traditional powder feeder 7, but does not influence the integral layout of former powder feeder.The powder feeder of transformation
It can not only work in a humid environment, moreover it is possible to the powder of poor fluidity be allow to pass through continual and steady defeated of stirring motor
Go out, improves production efficiency.And storage tube 1 in be full of inert gas, so drying when, can to avoid Powder Oxidation and completely
Eliminate the possibility of oxide heat explosion, stirring motor can allow powder fully to dry, improve spraying, deposition quality.
Above-described embodiment is only that the simplification embodiment of the utility model is described, not to the utility model
Range is defined, and under the premise of not departing from the spirit of the design of the utility model, is appointed to what technical solutions of the utility model were made
