Abstract
A silica powder charging device is characterized in that a cyclone separator is arranged above a charging opening of a silica powder bin; a discharging opening of the cyclone separator is connected with the charging opening of the silica powder bin; an inlet of the cyclone separator is connected with a storage bin through a material suction pipe; the storage bin is arranged on the first floor or in a trough; a slope surface is arranged at the bottom of the storage bin according to the stacking angle of silica powders; the orifice of the material suction pipe is arranged at the slope bottom; an air outlet at the upper end of the cyclone separator is connected with a water circulation vacuum pump through an air suction pipe; a dust filter and a negative-pressure buffering chamber are sequentially arranged on the air suction pipe between the cyclone separator and the water circulation vacuum pump; and materials recovered by the dust filter can be returned to the storage bin. The silica powder charging device has a simple structure, and can realize full-automatic charging control and eliminate dust pollution, so as to improve the working environment and reduce the labor intensity of workers.
Description
Technical field
The utility model relates to a kind of polysilicon, monocrystalline silicon production technology, particularly a kind of silica flour feeding device.
Background technology
In the production of polysilicon production process, need add pan feeding in the silica flour feed bin, in the prior art, be by electric block hopper to be hung on, and artificial emptying is poured in the feed bin, and its weak point is: dust is big, and labor strength is big, and operating environment is abominable.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed the silica flour feeding device of a kind of degree of automation height, no dust pollution.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of silica flour feeding device, be characterized in: above the charge door of silica flour feed bin, be provided with cyclone, the charge door of the discharging opening of cyclone and silica flour feed bin joins, the import of cyclone is joined by suction tube and storage bin, the air outlet of cyclone upper end joins by aspiration channel and water-circulating vacuum pump, and cyclone is provided with dust filter unit and negative pressure surge chamber successively to the aspiration channel between the water-circulating vacuum pump.
The utility model compared with prior art, by the swabbing action of water-circulating vacuum pump, in cyclone, form negative pressure, draw silica flour by suction tube from storage bin, silica flour rotates separation in cyclone, fall into the silica flour feed bin by deadweight, a small amount of micronic dust reclaims through air outlet to dust filter unit, and it is simple in structure, can realize full-automatic reinforced control, no dust pollution has improved operating environment, has alleviated labor strength.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
The specific embodiment
A kind of silica flour feeding device, above the charge door of silica flour feed bin 3, be provided with cyclone 2, the charge door of the discharging opening of cyclone 2 and silica flour feed bin 3 joins, the import of cyclone 2 is joined by suction tube and storage bin 1, storage bin 1 is arranged in Stall or the geosyncline, size in storage bin 1 bottom according to the stocking angle of silica flour, be provided with one domatic, the mouth of pipe of suction tube is located at slope bottom.
The air outlet of cyclone 2 upper ends joins by aspiration channel and water-circulating vacuum pump 6, and cyclone 2 is provided with dust filter unit 4 and negative pressure surge chamber 5 successively to the aspiration channel between the water-circulating vacuum pump 6.The material that dust filter unit 4 reclaims can be put in the storage bin once more.
