Description

Technical Field

[0001] The utility model relates to the technical field of silica crushing, in particular to a silica feeding structure for metallic silicon production. Background Art

[0002] The existing silica, as the raw ore for the production of metallic silicon, needs to be crushed into pieces of suitable size by a crusher before melting at high temperature. However, the existing crushers are usually fed manually. Due to the need for continuous processing and feeding, the dust generated during the crushing will overflow through the feeding port with the backflow of the airflow, affecting the workers' feeding;

[0003] Publication No. CN220780696U discloses a dust collecting structure of a pulverizer, comprising a body, a feed port fixedly arranged above one end of the body, a discharge trough fixedly arranged below the other end of the body, a through hole fixedly opened on the end face of the discharge trough, a discharge port fixedly connected in the through hole, and a dust collecting device fixedly arranged on one side of the body; in the dust collecting structure of the pulverizer, the dust generated in the pulverizer is collected by the dust collecting device, which is combined with the body through a connecting pipe, and the dust floating in the body is collected by the exhaust fan in the fixed part through the connecting pipe, and the large pieces of light materials are filtered through the filter net in the connecting pipe to avoid clogging the pipeline and affecting the operation, and the dust is collected by the integrated bag, and the gas extracted from the pulverizer by the exhaust fan is discharged through the integrated bag, but the dust is left in the integrated bag, which greatly reduces the impact of the dust generated by the pulverizer during operation on the human body, but the patent still has the following problems in actual use:

[0004] The above-mentioned method directly extracts the dust inside the crusher through a vacuum pump, but the dust generated in the silica processing process is also an effective resource, so the integrated bag in the above-mentioned device needs to be cleaned and the dust is recovered. However, since the crusher generates a lot of dust during production, the dust in the integrated bag accumulates quickly and needs to be cleaned frequently, which is more troublesome. In addition, since the feeding amount cannot be directly observed during feeding, when a large amount of stone is fed at a single time, the stone may block the feeding port.

[0005] A silica delivery structure for producing metallic silicon is proposed to solve the above-mentioned problems. Utility Model Content
