Abstract
The invention provides a method for separating metal powder off line, which is used for multi-pass classification of the metal powder to form products with different particle sizes. The method comprises the following steps that: the metal powder is classified by a classifier, and the metal powder with a first particle size enters a first collecting bin; the residual metal powder enters a first-stage cyclone classifier, and the metal powder with a second particle size enters a second collecting bin; the residual metal powder enters a second-stage cyclone classifier, and the metal powder with a third particle size enters a third collecting bin; the residual metal powder which passes through the second-stage cyclone classifier enters a third-stage cyclone classifier, and the metal powder with a fourth particle size enters a fourth collecting bin; and the residual metal powder enters a dust removing box, and the metal powder with a fifth particle size enters a fifth collecting bin. By the method for separating the metal powder off line, the production speed is improved, the particle size distribution of the products is narrower, the particle size of the powder is more uniform, the aims of improving product quality and enriching product specifications are fulfilled, and manpower and material resources are saved.
Description
Technical field
The present invention relates to a kind of implementation method of industrial process, related in particular to a kind of off-line separation method of metal dust.
Background technology
Metal dust is used to a lot of commercial production, but the different production requirement needs the metal dust of different sizes, so need metal dust be separated.
The traditional metal powder production mainly depends on the ball milling production line, and product quality receives the influence of milling system equipment and technological parameter bigger.Because the classification efficiency of grader is limited on the ball milling line at present; Be difficult to produce the high-test metal powder-product of particle diameter narrow distribution; And the metal dust product specification of producing is single; Be difficult to satisfy the demand of market, can not satisfy people's demand high-end metal dust and diversified specification metal dust.
Summary of the invention
The present invention mainly is the deficiency to prior art, and a kind of implementation method that is applicable to the metal dust that disposable separating particles varies in size is provided.
To achieve these goals, the present invention provides following technical scheme:
The off-line separation method of metal dust is used for metal dust is passed through the product that multiple tracks is classified into different-grain diameter, and it comprises:
Metal dust is through the grader classification, and the first particle diameter metal dust that particle diameter is bigger advances first and collects feed bin, and the less metal dust of particle diameter gets into first order whirlwind clarifier;
Residual metallic powder through grader gets into first order whirlwind clarifier, and wherein, the second particle diameter metal dust that particle diameter is bigger advances second and collects feed bin, and the less metal dust of particle diameter gets into second level whirlwind clarifier;
Residual metallic powder through first order whirlwind clarifier gets into second level whirlwind clarifier, and wherein, the 3rd particle diameter metal dust that particle diameter is bigger advances the 3rd and collects feed bin, and the less metal dust of particle diameter gets into third level whirlwind clarifier;
Residual metallic powder through second level whirlwind clarifier gets into third level whirlwind clarifier, and wherein, the 4th particle diameter metal dust that particle diameter is bigger advances the 4th and collects feed bin, and the less metal dust of particle diameter gets into dust cleaning case;
Residual metallic powder through third level whirlwind clarifier gets into dust cleaning case, and the 5th particle diameter metal dust advances the 5th and collects feed bin.
As a preferred embodiment of the present invention, the off-line separation method of said metal dust carries out under enclosed environment.
As a preferred embodiment of the present invention, the size of the said first particle diameter metal dust, the second particle diameter metal dust, the 3rd particle diameter metal dust, the 4th particle diameter metal dust, the 5th particle diameter metal dust reduces successively.
The off-line separation method of said metal dust; Feed intake through disposable; Can in a production procedure, simultaneously metal dust be classified according to the difference of its granular size, and discharge according to the grade of size; Make more homogeneous of powder diameter like this, reached the purpose of improving the quality of products and enriching product specification; In addition, the off-line separation method of said metal dust not only can be saved much production equipments in early stage before separating, and has shortened production line, has saved manpower and materials, and has accelerated the speed of producing.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail,, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to the understanding by those skilled in the art.
Consult Fig. 1, Fig. 1 is the system flow chart of the off-line separation method of metal dust of the present invention.
The off-line separation method of metal dust is used for metal dust is passed through the product that multiple tracks is classified into different-grain diameter, and it comprises:
Metal dust is through the grader classification, and the first particle diameter metal dust that particle diameter is bigger advances first and collects feed bin, and the less metal dust of particle diameter gets into first order whirlwind clarifier;
Residual metallic powder through grader gets into first order whirlwind clarifier, and wherein, the second particle diameter metal dust that particle diameter is bigger advances second and collects feed bin, and the less metal dust of particle diameter gets into second level whirlwind clarifier;
Residual metallic powder through first order whirlwind clarifier gets into second level whirlwind clarifier, and wherein, the 3rd particle diameter metal dust that particle diameter is bigger advances the 3rd and collects feed bin, and the less metal dust of particle diameter gets into third level whirlwind clarifier;
Residual metallic powder through second level whirlwind clarifier gets into third level whirlwind clarifier, and wherein, the 4th particle diameter metal dust that particle diameter is bigger advances the 4th and collects feed bin, and the less metal dust of particle diameter gets into dust cleaning case;
Residual metallic powder through third level whirlwind clarifier gets into dust cleaning case, and the 5th particle diameter metal dust advances the 5th and collects feed bin.
The size of the said first particle diameter metal dust, the second particle diameter metal dust, the 3rd particle diameter metal dust, the 4th particle diameter metal dust, the 5th particle diameter metal dust reduces successively.
Off-line separation method through said metal dust; Adjustment metal dust size; Separate the meal of charging powder and fine powder, thereby and make the particle diameter of product distribute further to narrow down to promote product quality greatly, produce the metal dust product of high color intensity.
The substandard product that the metal dust production line is produced; Can use the off-line separation method of said metal dust further to handle; Conversely; The small amounts of by-products of the off-line separation method output of said metal dust also can be put into the metal dust production line again and digest, and two systems complement one another and increased validity and the flexibility of handling byproduct.
