Abstract
A kind of multilevel screen for sieving silicon carbide micro-powder, it comprises material storing tank, it is characterized in that: be connected with screen(ing) machine I below by conveyance conduit at material storing tank, screen(ing) machine I is connected with screen(ing) machine II by material conveying pipe, screen(ing) machine II is connected with material storage tank by conveyance conduit, screen(ing) machine II internal upper part is provided with stirring turning cylinder, and the bottom in screen(ing) machine II is provided with at least two-layer screen cloth.The utility model structure is simple, be easy to install, and the setting of screen(ing) machine I makes oarse-grained silicon carbide micro-powder first be screened out, and avoids blocking mesh, and the setting of screen(ing) machine II and stirring shaft substantially increases screening efficiency and screening quality.
Description
Technical field
The utility model relates to screen technology field, particularly relates to a kind of multilevel screen for sieving silicon carbide micro-powder.
Background technology
Because silicon carbide micro-powder is mainly used in Abrasive Industry, the particle size of carborundum is very large on Linear cut impact, so have particular/special requirement to the classification of micro mist, current domestic silicon carbide micro-powder is by the restriction of existing bolting precision, bulky grain can not be had in micro mist to occur, institute thinks and reaches international and home products requirement, and general production all adopts screening machine to carry out classification.What Conventional silicon carbide micro mist vibrosieve equipment generally adopted is that the quantity of one-level screening or the screen cloth increasing screen(ing) machine is to increase screening effect, the screening of this form just easily blocks sieve aperture when running into bulky grain silicon carbide micro-powder, high pressure water washing must be carried out if desired, not only add energy consumption, also have impact on classification efficiency, be therefore necessary to be improved existing technology.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming existing screen cloth, provides a kind of multilevel screen for sieving silicon carbide micro-powder.Particular content is as follows:
A kind of multilevel screen for sieving silicon carbide micro-powder, it comprises material storing tank, be connected with screen(ing) machine I below by conveyance conduit at material storing tank, screen(ing) machine I is connected with screen(ing) machine II by material conveying pipe, screen(ing) machine II is connected with material storage tank by conveyance conduit, screen(ing) machine II internal upper part is provided with stirring turning cylinder, and the bottom in screen(ing) machine II is provided with at least two-layer screen cloth.
The sieve aperture of the screen cloth of screen(ing) machine I is 500 orders, and arranges garbage collection tank I (8) in the below of screen(ing) machine I.
The sieve aperture of the screen cloth of screen(ing) machine II is 400 orders, and arranges garbage collection tank II (9) in the below of screen(ing) machine II.
The screen cloth of described screen(ing) machine II is three layers.
The utility model structure is simple, be easy to install, and the setting of screen(ing) machine I makes oarse-grained silicon carbide micro-powder first be screened out, and avoids blocking mesh, and the setting of screen(ing) machine II and stirring shaft substantially increases screening efficiency and screening quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 material storing tank; 2 screen(ing) machines I; 3 material conveying pipes; 4 turning cylinders; 5 screen(ing) machines II; 6 screen clothes; 7 material storage tanks; 8 garbage collection tanks I; 9 garbage collection tanks II.
Detailed description of the invention
For sieving a multilevel screen for silicon carbide micro-powder, it comprises material storing tank 1, is connected below by conveyance conduit 3 at material storing tank with screen(ing) machine I 2, and the sieve aperture of the screen cloth of screen(ing) machine I is 500 orders, arranges garbage collection tank I 8 in the below of screen(ing) machine I.Screen(ing) machine I is connected with screen(ing) machine II 5 by material conveying pipe 3, and the sieve aperture of the screen cloth of screen(ing) machine II is 400 orders, arranges garbage collection tank II 9 in the below of screen(ing) machine II.Screen(ing) machine II is connected with material storage tank 7 by conveyance conduit, and screen(ing) machine II internal upper part is provided with stirring turning cylinder 4, and the screen cloth 6 that the bottom in screen(ing) machine II is arranged is three layers.
During use, material enters screen(ing) machine I 2 and carries out first time screening from holding vessel 1, in first time screening, the silicon carbide micro-powder of larger particles is prevented from entering screen(ing) machine II 5, prevent sieve pore blockade screen cloth 6, when in screen(ing) machine II stored in a certain amount of silicon-carbide particle time, open the valve bottom screen(ing) machine II, make not enter in waste material storage tank II 9 by the silicon-carbide particle of screen cloth.Under the stirring of rotating shaft 4, shorten the time of the less material of particle diameter to material layer lower part movement, thus silicon carbide micro-powder is entered in material storage tank 7 by sieve aperture with the fastest speed.
Claims (4)
