Preferably, the upper part of the inner part of the main body is in a conical structure with a smaller upper part and a larger lower part.
Preferably, the main body is internally fixed with a motor, a cleaning brush is fixed on an output shaft of the motor, the cleaning brush comprises a brush plate fixed with the output shaft of the motor, and bristles are uniformly distributed on the brush plate.
Preferably, the motor is fixed in the main body through the fixing frame.
Preferably, the bottom of the main body is provided with a plurality of supporting legs.
The powder selecting device is simple and ingenious in structure and convenient to use, powder is selected through the screen, the powder passing through the screen enters a finished product area through the discharging pipe, and the powder which cannot pass through the screen is sent back into the pulverizer for pulverizing again, so that the output finished product powder meets the granularity requirement, and the quality of a finished product is improved.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a schematic cross-sectional view of the present utility model.
Fig. 3 is a schematic view of the structure of the cleaning brush of the present utility model.
Description of the embodiments
The following describes the embodiments of the present utility model in further detail with reference to the drawings.
From fig. 1 to fig. 3, it can be seen that a powder selecting and feeding mechanism for a mine pulverizer comprises a main body 1, wherein a feed inlet 2 connected with a discharge hole of the pulverizer is arranged on the side edge of the bottom of the main body 1, a first fan 3 is arranged at the inner bottom of the main body 1, a screen 4 obliquely arranged is arranged inside the main body 1, a feed back pipe 5 extending out of the main body 1 is arranged on one side, close to the upper side, of the bottom of the screen 4, of the feed back pipe 5 is connected with a feed back hole of the pulverizer, a first discharge pipe 6 extending out of the main body 1 is arranged on one side, close to the lower side, of the upper portion of the screen 4, a second fan 7 is arranged at the upper end of the main body 1, a second discharge pipe 8 is arranged on the side edge of the upper end of the main body 1, and the first discharge pipe 6 is connected into the second discharge pipe 8.
In the specific use of the present utility model,
the feed inlet 2 is connected with the discharge gate of mine milling machine, feed back pipe 5 is connected with the feed back mouth of mine milling machine, start mine milling machine and equipment, the mill is with the raw materials discharge from the discharge gate after grinding into powder, get into inside main part 1 through feed inlet 2, first fan 3 and second fan 7 combined action, upwards blow the powder, after powder contacts with screen cloth 4, the powder that satisfies the granularity requirement is discharged from second discharging pipe 8 through screen cloth 4, the powder that does not satisfy the granularity requirement is blocked by screen cloth 4, because screen cloth 4 slope is arranged, the powder moves upwards along screen cloth 4, discharge back into in the mine milling machine from feed back pipe 5, smash again, after shutting down, the powder in screen cloth 4 top can be followed first discharging pipe 6 and is discharged into second discharging pipe 8, get into the finished product district and collect.
