CN204074513U - A kind of winnowing machine - Google Patents

Abstract

The utility model discloses a kind of winnowing machine, belong to breeze pneumatic separator technical field, comprise selection by winnowing collecting bin, the bottom of selection by winnowing collecting bin offers the first discharge gate, and the first discharge gate place is provided with blower fan; The air outlet of blower fan is connected with the first discharge gate by pipeline, and air inlet communicates with air; The bottom of selection by winnowing collecting bin also offers the second discharge gate, and the second discharge gate place is connected with the drainage conduit of circular cone tubular.By blower fan, the selection by winnowing clout high wind of originally discharging from its first discharge gate in selection by winnowing collecting bin is kicked up, reach secondary selection by winnowing object, make selection by winnowing clout after secondary selection by winnowing, will wherein relatively meal order discharge again grind, economical and efficient, add output, avoid qualified powder orders a large amount of in selection by winnowing clout and meal order together grinds again and lowers efficiency.

Description

a sorting machine

technical field

The utility model relates to the technical field of mineral powder winnowing equipment, in particular to a winnowing machine.

Background technique

After the ore powder is ground by the ball mill, it enters the winnowing machine for winnowing. After winnowing, the remaining material enters the winnowing collection bin and is discharged from a discharge port set at the bottom, and enters the ball mill again for grinding, but the winnowing out There are about 70% of the qualified powder in the remaining material, which also followed into the ball mill for re-grinding, resulting in a waste of production resources and reducing efficiency.

Utility model content

The purpose of the utility model is to provide a winnowing machine to solve the problem of reduced efficiency caused by the fact that there are still many qualified powders in the remaining material after winnowing in the existing winnowing machine that are not selected and re-entered for grinding.

In order to realize the purpose of the utility model, the technical solution adopted is: a kind of winnowing machine, comprising the winnowing collection bin, the bottom of the winnowing gathering bin is provided with a first discharge port, the first discharge port is provided with a fan; The air outlet is connected to the first discharge port through a pipe, and the air inlet is connected to the atmosphere; the bottom of the winnowing collection bin is also provided with a second discharge port, and the second discharge port is connected to a conical cylindrical discharge pipe.

Further, a feed opening is opened on the top of the winnowing collection bin.

The beneficial effect of the utility model is that, through the blower fan, the air-selected remaining material originally discharged from the first material discharge port in the air-selected collection bin is raised by strong wind, so as to achieve the purpose of secondary air-selected, so that the air-selected remaining material is discharged through the second air-selection. After wind selection, the relatively coarse powder mesh is discharged for re-grinding, which is economical and efficient, increases the output, and avoids a large number of qualified powder mesh and coarse powder mesh in the leftover material of air separation to be re-ground together to reduce efficiency.

Description of drawings

Fig. 1 is the schematic structural view of the winnowing machine provided by the utility model.

Detailed ways

The utility model will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

Fig. 1 has shown the winnowing machine that the utility model provides, comprise winnowing collecting bin 1, the bottom of winnowing gathering bin 1 is provided with the first material discharge port, and the first discharge port place is provided with blower fan 2; The air outlet is connected to the first discharge port through a pipe, and the air inlet is connected to the atmosphere; the bottom of the winnowing collection bin 1 is also provided with a second discharge port, and the second discharge port is connected to a conical cylindrical discharge pipe 3 , The top of the winnowing collection bin 1 is provided with a feed inlet.

The remaining materials of the first winnowing are blown up under the action of the wind force of the fan, so that the heavier coarse powder falls to the bottom under the action of gravity and is discharged from the second discharge port through the conical discharge pipe 3 , into the ball mill for grinding again.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
