Abstract

The utility model discloses a kind of fluorescent powder grain vibration separation screen, comprise the base fixed on the ground, described base connects vibratory sieve cylindrical shell by Compress Spring, and described vibratory sieve cylindrical shell sets gradually feeding mouth, coarse fodder mouth, the first screen pack, discharging opening, the second screen pack, splicing plate, fines mouth and vibrating motor from top to bottom.The utility model structure is simple, easy to operate, can separate the fluorescent powder grain meeting particle size range and require by Automatic sieve.

Description

A kind of fluorescent powder grain vibration separation screen
Technical field
The utility model relates to a kind of vibrosieve equipment, and what be specifically related to is a kind of fluorescent powder grain vibration separation screen.
Background technology
Along with the develop rapidly of various powder industry, very strict for the requirement of powder granularity in production process, grading technology and corollary apparatus determine the distribution of powder granularity.Adopt rational grading technology, configure suitable grading plant and the powder tool obtaining high accuracy granularity is fast of great significance.
Different LED packaging technology needs the fluorescent powder grain of different-grain diameter scope, at present, grain size grading carried out to fluorescent material main or artificial, in the process of screening, workman more or less can suck fluorescent powder grain, this can work the mischief to the health of workman, and when needing the fluorescent powder grain of certain particle size range, often needs to sieve for twice, sieving for twice not only, efficiency is lower, and fluorescent material often also loss can occur in the process turning sieve.
Summary of the invention
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of fluorescent powder grain vibration separation screen, and structure is simple, easy to operate, can screen the fluorescent powder grain of different-grain diameter size.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of fluorescent powder grain vibration separation screen, comprise the base fixed on the ground, described base connects vibratory sieve cylindrical shell by Compress Spring, and described vibratory sieve cylindrical shell sets gradually feeding mouth, coarse fodder mouth, the first screen pack, discharging opening, the second screen pack, splicing plate, fines mouth and vibrating motor from top to bottom.
Preferably, described splicing plate becomes 30 ° with horizontal plane.
Preferably, the order number of described first screen pack is less than the order number of described second screen pack, and fluorescent material is through the first screen pack, and larger particle is discharged from coarse fodder mouth, and less particle is discharged from fines mouth, and namely the particle of discharging from discharging opening is required particle.
Preferably, described coarse fodder mouth, described discharging opening and described fines mouth are parallel to horizontal plane, and described feeding mouth is perpendicular to horizontal plane.
The beneficial effects of the utility model are:
The utility model is novel in design, structure is simple, easy to use, design two-layer screen cloth, discharged from coarse fodder mouth by the particle being greater than required particle diameter respectively, the particle diameter being less than required particle is discharged from fines mouth, finally obtains the fluorescent powder grain meeting particle size range requirement, like this by regulating the order number of two-layer screen cloth, can actual conditions be made a thorough investigation of sieve out required fluorescent powder grain.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 overall structure schematic diagram.
Number in the figure illustrates: 1, feeding mouth, 2, vibratory sieve cylindrical shell, and the 3, first screen pack, 4, coarse fodder mouth, the 5, second screen pack, 6, discharging opening, 7, splicing plate, 8, fines mouth, 9, vibrating motor, 10, Compress Spring, 11, base.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Embodiment 1
With reference to shown in Fig. 1, a kind of fluorescent powder grain vibration separation screen, comprise the base 11 fixed on the ground, described base 11 connects vibratory sieve cylindrical shell 2 by Compress Spring 10, fluorescent powder grain to be filtered is poured in vibratory sieve from feeding mouth 1, open the power switch of the vibrating motor 9 bottom vibratory sieve, vibratory sieve starts vibration under the drive of vibrating motor 9, when fluorescent material is first screen pack 3 of 300 by order number, thinner particle falls by the first screen pack 3 the second screen pack 5 that order number is 450, thicker particle is stopped by described first screen pack 3, discharge from coarse fodder mouth 4, in the process of shaker vibration, the fluorescent material meeting particle size range requirement is stopped by described second screen pack 5, discharge from discharging opening 6, all the other very thin particles drop on splicing plate 7 by the second screen pack 5, and discharge from fines mouth 8.
Preferably, described splicing plate 7 becomes 30 ° with horizontal plane.
Preferably, the order number of described first screen pack 3 is less than the order number of described second screen pack 5, can select the first screen pack 3 and the second screen pack 5 of different meshes according to the magnitude range of required fluorescent material particle diameter.
Preferably, described coarse fodder mouth 4, described discharging opening 6 and described fines mouth 8 are parallel to horizontal plane.
Preferably, described feeding mouth 1 is perpendicular to horizontal plane.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
