Abstract
The utility model provides a powder grading plant, which is very suitable for the grading of the powder with the single component of metal, non-metal, etc. The utility model mainly comprises a wind chamber for the air to enter and a grading chamber for the air to enter after passing through a sloping wind-distribution plate and forming airflow with balanced velocity. The thick and fine granule grade products are graded by a wind inlet chamber through the wind-distribution plate and the grading chamber with no need of a screen and mechanical rotating members. The maintenance working capacity is little, and the grading efficiency and the grading precision are high. In the whole grading process, the grading efficiency and the grading precision can not be changed. The grading granularity and precision can be flexibly controlled through regulating the amount and the wind pressure and the sloping angle of the wind-distribution plate. The utility model has wide practicability.
Description
One, technical field
The utility model relates to a kind of powder classification device, is particularly useful for the classification of metal, single component powder such as nonmetal.
Two, background technology
At present, powder mainly contains mechanical picker extension set and mechanical rotary blade grader by the device of particle size separation or classification, and main screen cloth of its structure or mechanical rotary blade parts are formed.When adopting screening machine that fine powder is sieved, can occur the plug-hole phenomenon very soon, along with the continuity of activity duration, screening efficiency can descend gradually, and screen cloth can be out of shape, breakage, makes partition size change, and needs often to change screen cloth; On the other hand, when the application screening machine sieves fine powder, can contain a large amount of fine particle stage materials in the coarse fraction material, cause the fine powder loss near screen size.When adopting mechanical rotary blade grader particularly metal dust such as some high temperature alloys carrying out classification to fine powder, can cause the quick wearing and tearing of classifying turbine, and bring pollution, simultaneously to product, bearing can cause wearing and tearing even parking accident because of the poorly sealed powder of sneaking into.
Three, technology contents
1. goal of the invention
In view of the deficiency that prior art exists, the purpose of this utility model provides a kind of simple in structure, and is effective, the powder classification device that efficient is high.
2. technical scheme
A kind of powder classification device of the utility model, it passes the grading room that forms the equal permanent air-flow of speed behind the tilting air distribution plate and enter by an air compartment that enters gas and gas and forms, the top, inclination angle of described tilting air distribution plate is provided with charging aperture, the below is provided with the collection mouth that enters the coarse fraction product, and described grading room is connected with the fine fraction powder collector.
A kind of powder classification device of the utility model, described grading room top is vertical, and the bottom is the arc-shaped transition body, and grading room and air distribution plate joining place are in plumbness, the fine fraction powder collector is connected with the pipeline at grading room top, is provided with the porous material screen pack in it.
3. technique effect
A kind of powder classification device of the utility model, be best suited for the classification of metal, single component powder such as nonmetal, adopt inlet air plenum by air distribution plate and grading room with the grading of thickness grade, compared with prior art, no screen cloth, there is not mechanical rotary part, its maintenance workload is little, classification efficiency and effectiveness of classification height, in whole classification process, classification efficiency and effectiveness of classification can not change, can control partition size and precision neatly by regulated quantity and blast and air distribution plate angle of inclination, have practicality widely.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Five, the specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
A kind of powder classification device of the utility model, as shown in the figure, it is mainly by an inlet air plenum 1, tilted-putted air distribution plate 2, form with the grading room 3 of the equal permanent air-flow of admission velocity, the top, inclination angle of tilted-putted air distribution plate 2 is provided with charging aperture 4, and the below is provided with the collection mouth 6 that enters the coarse fraction product, and the inclination angle of air distribution plate 2 can be adjusted according to on-site actual situations.Grading room 3 tops are vertical, the bottom is the arc-shaped transition body, grading room 3 is in plumbness with air distribution plate 2 joining places, grading room 3 is connected with fine fraction powder collector 5, and fine fraction powder collector 5 links together with the pipeline at grading room 3 tops, is provided with the porous material screen pack in the gatherer 5, so that the fine fraction powder is collected, is filtered, the gas that gatherer 5 is discharged can utilize, and can adopt circulating fan to be communicated with inlet air plenum 1 circulation air feed, saves the energy.
Its course of work: gas is pressed in the air compartment 1 by blower fan, after the gas that enters air compartment 1 passes the air distribution plate 2 of inclination, enters the uniform air flow field that forms constant airspeed in the grading room 3 equably.Powder material is after charging aperture 4 enters inclined distributor 2, and the fine fraction powder is carried away by air-flow, and collecting through fine fraction powder collector 5 becomes the fine fraction product; The coarse fraction powder then rolls downwards along inclined distributor 2, is drained into the coarse fraction product from the discharging opening of air distribution plate lower end and collects mouthfuls 6, thereby reach purpose with particle classifying.
Claims (4)
1. powder classification device, it is characterized in that: it is passed by an air compartment (1) that enters gas and gas, and tilting air distribution plate (2) back forms the equal permanent air-flow of speed and the grading room (3) that enters is formed, the top, inclination angle of described tilting air distribution plate (2) is provided with charging aperture (4), the below is provided with the discharging opening (6) of coarse fraction product, and described grading room (3) also is connected with fine fraction powder collector (5).
2. a kind of powder classification device according to claim 1 is characterized in that: described grading room (3) top is vertical, and the bottom is the arc-shaped transition body, and grading room (3) is in plumbness with air distribution plate (2) joining place.
