Abstract

The utility model relates to a vibration fine screening system for powdered green silicon carbide, which is characterized by comprising a vibration screen (1), a screw feeder (2) and a dust collector (4). A feed inlet of the vibration screen (1) is connected with a discharge outlet of the screw feeder, a charging hopper (3) is arranged at the top of the screw feeder (2), and dust collector suction ports (5) are arranged above a charging port at the top of the charging hopper (3) and the feed inlet at the top of the vibration screen (1) respectively and connected with an air outlet of the dust collector (4) through pipelines. The screw feeder is additionally arranged in front of the vibration screen of the vibration fine screening system for powdered green silicon carbide, and the charging hopper is disposed at the top of the screw feeder, so that charging is convenient. The screw feeder is capable of uniformly feeding the powdered green silicon carbide into the vibration screen, so that screening quality is higher. Since the dust collector suction ports are arranged above the charging hopper and the vibration screen, dust which is blown out can be sucked away, pollution of operation environment is avoided, and health of workers is guaranteed.

Description

The vibration fine screen system of green silicon carbide powder
Technical field
The utility model relates to a kind of vibration fine screen system of green silicon carbide powder, is used for sending the green silicon carbide powder after the oven dry to vibratory sieve and sieves.
Background technology
Green silicon carbide powder is the important materials of making products such as solar silicon wafers, semi-conductor silicon chip, engineering ceramics, heating element heater, high grade refractory, and is along with greatly developing of new material science, increasingly high to the quality requirement of silicon carbide micro-powder.In the production of high-quality green silicon carbide powder, green silicon carbide powder need be sent into the powder that will sieve into the different size size in the vibratory sieve later in oven dry, reinstalls in the finished product packing bag and sells.Yet vibratory sieve in the past is directly reinforced to vibratory sieve from loading hopper when green silicon carbide powder is sieved, not only reinforced inconvenience, and can't be evenly reinforced in vibratory sieve, make that the screening quality of vibratory sieve is not high.And in loading hopper when reinforced, the powder loading hopper of blowing out easily, thus pollute working environment, influence workers'health.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of convenient feeding, charging even, and the vibration fine screen system of the green silicon carbide powder that does not pollute the environment.
The purpose of the utility model is achieved in that
The vibration fine screen system of the utility model green silicon carbide powder; Involving vibrations sieve, screw feeder and deduster; The feeding mouth of said vibratory sieve links to each other with the discharging opening of screw feeder; The top of said screw feeder is provided with loading hopper, and the charge door at said loading hopper top and the feeding mouth at vibratory sieve top top are equipped with the deduster suction inlet, and said deduster suction inlet links to each other with the air outlet of deduster through pipeline.
Compared with prior art, the beneficial effect of the utility model is:
The vibration fine screen system of this green silicon carbide powder has added screw feeder before vibratory sieve, loading hopper is arranged on screw feeder top, not only convenient feeding; And screw feeder can be delivered to green silicon carbide powder in the vibratory sieve equably; Make screening quality higher, and be equipped with the deduster suction inlet above the feeding mouth at the charge door at loading hopper top and vibratory sieve top, can siphon away the dust of blowing out; Thereby avoided working environment contaminated, guaranteed workers'health.
Description of drawings
Fig. 1 is the structural representation of the vibration fine screen system of the utility model green silicon carbide powder.
Wherein: vibratory sieve 1, screw feeder 2, loading hopper 3, deduster 4, deduster suction inlet 5.
The specific embodiment
Referring to Fig. 1; The utility model relates to a kind of vibration fine screen system of green silicon carbide powder; Involving vibrations sieve 1, screw feeder 2 and deduster 4, the feeding mouth of said vibratory sieve 1 links to each other with the discharging opening of screw feeder, and the top of said screw feeder 2 is provided with loading hopper 3; The charge door at said loading hopper 3 tops and the feeding mouth at vibratory sieve 1 top top are equipped with deduster suction inlet 5, and said deduster suction inlet 5 links to each other with the air outlet of deduster 4 through pipeline.
Because loading hopper 3 is arranged on the top of screw feeder 2, make convenient feeding, and screw feeder 2 can deliver to green silicon carbide powder in the vibratory sieve 1 equably, make screening quality higher.And the feeding mouth at the charge door at loading hopper 3 tops and vibratory sieve 1 top top is equipped with deduster suction inlet 5, can siphon away the dust of blowing out, thereby avoid working environment contaminated, has guaranteed workers'health.
