Description

Jet mill separating device

Technical Field

The utility model relates to a neodymium iron boron magnetism nature material production field especially relates to an air current grinds separator.

Background

As shown in FIG. 1, the prior air mill comprises a feeding device, a grinding chamber, an air supply system, a cyclone separator 1 and a filtering device. Wherein the cyclone separator is connected with the grinding chamber and the filter. Feeding device sends neodymium iron boron permanent magnet material into grinding chamber, and the strong air current that provides through nitrogen compressor makes the powder collision each other realize the breakage, and the qualified powder after the breakage passes through the sorting wheel along with the air current and gets into cyclone and separates qualified granularity's powder, surplus gas and come out, and surplus gas gets into filter equipment, and filter equipment filters the collection with the superfine powder in the surplus gas, and clean gas flows back in the compressor, and qualified granule powder passes through separator, shale shaker export and collects in the fine powder jar.

However, in the production process, the lower cone of the cyclone separator 1 is connected with the vibrating screen 5 through the vase 2, and due to the cone angle of the separator and the vase structure, powder is easily accumulated and blocked in the vase, so that part of qualified powder enters the filtering device along with surplus gas, the superfine powder amount is increased, and the powder yield is reduced.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure reasonable jet mill separator has cancelled this transition device of vase, and the powder directly gets into the shale shaker through the cone of cyclone lower part, has effectually prevented that the powder from blockking up in cone lower part exit, has improved the powder yield.

In order to achieve the above object, the utility model provides an air current grinds separator, include: the cyclone separator is provided with a feed inlet on the side surface, a gas outlet on the top and a powder outlet on the bottom; the feed inlet is connected with the grinding chamber; a filter connected to the gas outlet; the inlet of the vibrating screen is connected with the powder outlet through a valve, and the qualified granular powder separated by the cyclone separator enters the vibrating screen; and the fine powder tank is connected with the outlet of the vibrating screen.

In a preferred embodiment, the bottom of the cyclone separator is an inverted cone, and the powder outlet is arranged at the bottom of the inverted cone.

In a preferred embodiment, the valve is a pneumatic valve.

In a preferred embodiment, the side of the inverted cone at the bottom of the cyclone is provided with pneumatic hammers.

Compared with the prior art, according to the utility model discloses an air current grinds separator has following beneficial effect: this jet mill separator's cyclone directly links to each other with the shale shaker through the valve, has cancelled this transition device of vase, and the powder directly gets into the shale shaker through the cone of cyclone lower part, and then gets into the fine powder jar to set up pneumatic hammer and play the effect of knocking at the cone of cyclone lower part, effectually prevented that the powder from blockking up in cone lower part exit, improved the powder yield.

Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

As shown in fig. 2, the specific structure of the airflow mill separation device according to the preferred embodiment of the present invention includes: cyclone 1, filter 2, valve 4, vibrating screen 5 and fine powder collection tank 6. This jet mill separator removes original vase between cyclone 1 and shale shaker 5, and the cone of cyclone lower part is connected with the shale shaker with certain tapering extension for coarse grain powder and superfine powder reasonable separation in the powder process eliminates the powder jam, improves the powder yield.

Specifically, the cyclone 1 has a feed inlet at the side, a gas outlet at the top and a powder outlet at the bottom. The feeding port is connected with the grinding chamber, the feeding device sends the neodymium iron boron permanent magnet material into the grinding chamber, the powder materials are mutually collided to realize crushing through strong airflow provided by the nitrogen compressor, and the crushed qualified powder materials enter the cyclone separator through the sorting wheel along with the airflow, so that the powder with qualified granularity and surplus gas are separated out.

The gas outlet is connected with the filter 2, so that the ultrafine powder enters the filter 2 along with the surplus gas, the filter 2 filters and collects the ultrafine powder in the surplus gas, and the clean gas flows back into the compressor.

The powder outlet is connected with the inlet of the vibrating screen 5 through a valve 4, and the qualified granular powder separated by the cyclone separator 1 enters the vibrating screen 5. This jet mill separator removes original vase between cyclone 1 and shale shaker 5, and cyclone passes through the valve and is connected with the shale shaker for the powder process in-process coarse grain powder and the reasonable separation of superfine powder, eliminate the powder jam, improve the powder yield.
