Problems solved by technology

[0004] The existing jet milling process is only applicable to the crushing of common items, but not applicable to some dangerous items
The reason is that many dangerous goods are easy to react with oxygen in the air and cause explosion easily.
In view of this, there is currently no jet milling equipment and crushing process for dangerous goods

Embodiment 1

[0034] see figure 1 , The present invention discloses a protective gas closed circulation pulverization equipment, the pulverization equipment is airtightly arranged;

[0035] The crushing equipment is provided with an inert gas inlet 61, and the inert gas inlet 61 can also be arranged at other positions.

[0036] The feeding device, the crushing device 6 and the gas-solid separation device 8 are sequentially connected; the feeding device feeds the material into the feed port 2 of the crushing device 6 . The gas in the feeding device and the pulverizing device 6 are all inert gases; in this embodiment, the inert gas is nitrogen.

[0037] The gas-solid separation device 10 separates sulfur solids and inert gases at the same time. The gas-solid separation device 10 may be a vortex separator or a centrifugal separator or the like.

[0038] The inert gas circulation loop 10 sends the inert gas separated from the gas-solid separation device 40 into the feeding device and the cru...

Embodiment 2

[0051] In this embodiment, the crushing equipment and crushing process of the present invention can be used to crush other inflammable and explosive dangerous articles except sulfur, and can also be used to crush ordinary articles.

Abstract

The invention discloses a protective gas airtight circulation crushing apparatus and a crushing process. The crushing apparatus is arranged in an airtight manner and comprises: a feeding device, a crushing device, a gas / solid separating device and an inert gas circulating loop, wherein the feeding device, the crushing device and the gas / solid separating device are connected in sequence; the gas in the crushing device is high-speed high-pressure inert gas; the inert gas circulating loop delivers the inert gas separated by the gas / solid separating device to the crushing device under the driving of a wind power driving unit, so the inert gas is recycled. The protective gas airtight circulation crushing apparatus and the crushing process provided by the invention can crush combustible and explosive dangerous articles safely and efficiently, such as sulfur.

Description

technical field [0001] The invention belongs to the technical field of jet milling, and relates to jet milling equipment, in particular to a protective gas closed circulation pulverization equipment; at the same time, the invention also relates to a protective gas closed circulation pulverization process. Background technique [0002] The crushing mechanism mainly applicable to the jet mill determines its wide application range and high fineness of the finished product. Typical materials include: superhard diamond, silicon carbide, metal powder, etc. [0003] The flow pulverizer, cyclone separator, dust collector and induced draft fan form a complete pulverization system. After the compressed air is filtered and dried, it is sprayed into the crushing chamber through the Laval nozzle at high speed. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The crushed materials rise with the suction force ...
