Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to an explosion-proof device for crushing high-magnesium alloys. Background Art

[0002] Before smelting high-magnesium alloys, the raw materials (lump materials) need to be crushed first, and then the raw materials are smelted according to the proportion after crushing.

[0003] The prior art discloses a fireproof and explosion-proof structure for crushing high-magnesium alloy (publication number: CN215313057U), comprising a crusher and a discharge channel arranged on the crusher, wherein the top of the crusher is provided with a feed port; a gas nozzle is provided in the middle and upper section of the discharge channel, and an inert gas, namely carbon dioxide, is supplied into the crusher through the gas nozzle; and carbon dioxide is introduced into the crusher from the discharge port position of the crusher.

[0004] The prior art proposes to introduce carbon dioxide gas into the grinder through the discharge port so that the grinding chamber is in a positive pressure environment and isolated from oxygen to achieve the purpose of explosion-proof. The prior art installs a pipe for conveying carbon dioxide gas on the wall of the discharge trough. Due to the density, the filled gas will be deposited at the bottom, and the open discharge trough is in an open state. Therefore, in the process of discharging the gas in the grinding chamber, a large part of the gas will be directly discharged from the opening of the discharge trough, which increases the loss. Secondly, the gas is discharged through the opening of the feed hopper. In the grinding chamber that is in a positive pressure environment, dust will overflow from the grinding chamber along with the discharge of carbon dioxide gas, causing air pollution around the grinder.

[0005] Therefore, we propose an explosion-proof device for crushing high-magnesium alloys. Utility Model Content
