[0032] The working principle of the utility model is as follows: when the walnut oil filter residue device is in use, the walnut oil is first introduced into the filter bag 132 inside the filter bucket 13 through the oil supply pipe 133, and then the hydraulic cylinder 141 is started to drive the extrusion cone 142 to move downward and squeeze the filter bag 132 located in the filter bucket 13, and the walnut oil flows out of the filter bucket 13 through the aperture of the filter bag 132, and then is introduced into the interior of the collecting bucket A12 below through the filter hole 131 of the filter bucket 13.
