Abstract
The present invention relates to a kind of powder methods of feeding, comprise the following steps：1) after powder enters powder cabin, at the different height of powder cabin, it is passed through into powder cabin by individually controlling the fluidizing gas that gas circuit controls so that powder fully fluidizes；2) powder fully after fluidisation equably flows out powder cabin, into and full of positive displacement quantitative conveying device, positive displacement quantitative conveying device is quantitatively conveyed powder, and the powder after quantitatively being conveyed to positive displacement quantitative conveying device carries out uniform subdivision again；3) method for utilizing venturi injection delivers into outer carrier pipe road after the powder after uniform subdivision again is mixed with conveying gas.The present invention can be ensured that powder continuous-stable enters outer carrier pipe road.
Description
Technical field
The present invention relates to a kind of method of feeding, more particularly to a kind of powder method of feeding.
Background technology
Often there is powder density not before powder enters conveying device in the powder method of feeding used in the prior art
The problems such as uniform mobility is bad so that powder can not continuous-stable enter outer carrier pipe road or be fed
Doses fluctuation is generated in journey and damages downstream process.
The content of the invention
In view of the above-mentioned problems, it can be ensured that powder continuous-stable enters outer carrier pipe the object of the present invention is to provide one kind
The powder method of feeding on road.
To realize above-mentioned technical purpose, the present invention takes following technical scheme：A kind of powder method of feeding, including following step
Suddenly：1) after powder enters powder cabin, at the different height of powder cabin, the fluidized gas by gas circuit is individually controlled to control is passed through into powder cabin
Body is so that powder fully fluidizes；2) fully fluidisation after powder equably flow out powder cabin, into and full of positive displacement quantitative it is defeated
Device is sent, positive displacement quantitative conveying device is quantitatively conveyed powder, and positive displacement quantitative conveying device is quantitatively conveyed
Powder afterwards carries out uniform subdivision again；3) method for utilizing venturi injection, by the powder after uniform subdivision again and conveying
Outer carrier pipe road is delivered into after gas mixing.
The fluidization gas of each independent control gas circuit of step 1) are all in accordance with the granularity of powder, real density, viscosity and water
Divide and be adjusted, detailed process is：When the granularity of powder, real density, viscosity and moisture value increase, fluidization gas are tuned up to protect
Demonstrate,prove fluid effect；When the granularity of powder, real density, viscosity and moisture value reduce, turn fluidization gas down and fluidized to avoid excessive,
Powder is caused to take out of；When powder cabin locally has powder to accumulate unsmooth flowing, fluidization gas are locally tuned up.
The air pressure of each independent control gas circuit of step 1) is in below 0.2MPa.
The fluidizing gas uses air or inert gas.
The present invention has the following advantages due to taking above technical scheme：1st, the present invention due to first from powder cabin not
With the fluidizing gas being passed through into powder cabin at height by gas circuit is individually controlled to control so that powder is fully fluidized, then right
Powder fully after fluidisation quantitatively conveys, and is quickly conveyed after finally carrying out uniform subdivision to the powder of quantitative conveying, therefore can
Ensure the entrance outer carrier pipe road of powder continuous-stable.2nd, the present invention is due to granularity, real density, viscosity and the water according to powder
Divide and adjust fluidization gas, therefore further ensure powder can fully fluidize, further ensure that powder being capable of continuous-stable
Into outer carrier pipe road.The present invention is at low cost, easy to operate to be can be widely applied in the supply of various powders.
Specific embodiment
The present invention is described in detail below by embodiment.
The powder method of feeding of the present invention, comprises the following steps：
1st, after powder enters powder cabin, the stream by gas circuit is individually controlled to control is passed through into powder cabin at the different height of powder cabin
Change gas, the air pressure of each independent control gas circuit in below 0.2MPa, the fluidization gas of each independent control gas circuit all in accordance with
Granularity, real density, viscosity and the moisture of powder are adjusted, so that powder fully fluidizes；
2nd, the powder fully after fluidisation equably flows out powder cabin, into and full of positive displacement quantitative conveying device, positive displacement
Powder is carried out quantitative conveying by quantitative conveyer, and the powder after quantitatively being conveyed to positive displacement quantitative conveying device carries out again
Uniform subdivision, further to reduce the fluctuation of instantaneous feed quantity；
3rd, using the method for venturi injection, quickly conveyed after the powder after uniform subdivision again is mixed with conveying gas into
Enter outer carrier pipe road.
In a preferred embodiment, the fluidization gas of each independent control gas circuit are all in accordance with the granularity, very close of powder
Degree, viscosity and moisture are adjusted, and detailed process is：When the granularity of powder, real density, viscosity and moisture value increase, tune up
Fluidization gas are to ensure fluid effect；When the granularity of powder, real density, viscosity and moisture value reduce, turn down fluidization gas with
It avoids excessively fluidizing, powder is caused to take out of；When powder cabin locally has powder to accumulate unsmooth flowing, fluidization gas are locally tuned up.
In a preferred embodiment, air or inert gas may be employed in fluidizing gas.
Above-described embodiment is merely to illustrate the present invention, and wherein implementation steps of each method etc. can be all varied from,
Every equivalents carried out on the basis of technical solution of the present invention and improvement, should not exclude in protection scope of the present invention
Outside.
