Vibratory screener with an adapter frame
View Patent ↗A vibratory screener apparatus has a housing with upper and lower ends, the lower end having a first mounting area characterized by a first attachment diameter. A drive assembly is employed to vibrate the apparatus. The drive assembly has a second mounting area characterized by a second attachment diameter to mount the frame to the drive assembly. An adapter frame is disposed between the drive assembly and the lower end of the housing. The adapter frame has a first end and a second end, the first end is characterized by the first attachment diameter and is attached to the lower end of the housing. The second end is characterized by the second attachment diameter and attached is to the drive assembly.
1. A vibratory screener apparatus having:
a housing with upper and lower ends, the lower end having a first mounting area characterized by a first attachment diameter;
a drive assembly that contains a motor for vibrating the apparatus, and having a second mounting area characterized by a second attachment diameter, different from the first attachment diameter, to mount an adapter frame to the drive assembly; and
the adapter frame disposed between the drive assembly and the lower end of the housing, the adapter frame having a first end and a second end, the first end characterized by the first attachment diameter and attached to the lower end of the housing, the second end characterized by the second attachment diameter and attached to the drive assembly, wherein the first attachment diameter is larger than the second attachment diameter.
2. A vibratory screener apparatus comprising:
a cover having a material inlet port;
a spacing frame attached to the cover and having a material outlet port and a screen positioned at a lower end of the spacing frame;
an adapter frame removably attached to the spacing frame and having a first end with a diameter substantially the same as a diameter of the spacing frame and having a second end with a diameter smaller than the diameter of the first end;
a discharge frame removably attached to the adapter frame and having a diameter substantially the same as the diameter of the second end of the adapter frame; and
a drive assembly removably mounted to the discharge frame.
3. The vibratory screener apparatus of claim 2 where the spacing frame is removably attached to the cover.
4. The vibratory screener apparatus of claim 2 wherein the drive assembly comprises an imbalanced-weight gyratory motor.
5. A vibratory screener apparatus having:
a housing with upper and lower ends, the lower end having a first mounting area characterized by a first attachment diameter;
a drive assembly that contains a motor for vibrating the apparatus, and having a second mounting area characterized by a second attachment diameter, different from the first attachment diameter, to mount an adapter frame to the drive assembly; and
the adapter frame disposed between the drive assembly and the lower end of the housing, the adapter frame having a first end and a second end, the first end characterized by the first attachment diameter and attached to the lower end of the housing, the second end characterized by the second attachment diameter and attached to the drive assembly, wherein the adapter frame is attached to the drive assembly by way of a drive plate, the drive plate attached on a lower surface to a plurality of springs that are attached to a motor.
6. The vibratory screener apparatus of claim 2 wherein the adapter frame is characterized by a conical shape.
7. The vibratory screener apparatus of claim 2 wherein the spacing frame and the discharge frame are substantially cylindrical in shape.
