The filter core is arranged between the upper filter component and the lower filter component. The filtration apparatus provided by the present invention has the following advantages that: the used filter material is novel; the effect is definite; the filter design is scientific and reasonable; the filter method is practical and convenient; with the apparatus, efficient removal of the leucocytes in the sample can be ensured, the most of the purified plasmodium-infected erythrocytes can be concurrently recovered.

The invention provides a device and method for removing ice cubes in a refrigerator by means of reciprocal vibration, and relates to field of articles of daily use. The device for removing the ice cubes in the refrigerator by means of reciprocal vibration comprises a left fixed box, wherein a reciprocating driving rod is arranged at the bottom of the left fixed box, the bottom of the reciprocatingdriving rod is bonded to the top of a side hollow fixed cylinder, the bottom of the side hollow fixed cylinder is bonded to the top of a connecting suction cup, and a right mounting box and a grabbing handle are bonded to the right side of the left fixed box. According to the device for removing the ice cubes in the refrigerator by means of reciprocal vibration, after the connecting suction cup is sucked on the ice surface, a driving motor controls a stirring rod to be in contact with protrusion particles, so that the connecting suction cup constantly makes reciprocal vibration after being connected with the ice cubes, and vibration force generated through vibration is utilized for gradually lowering the bonding force between the ice cubes and the inner wall of the refrigerator, which helps to remove large ice cubes. Meanwhile, the ice cubes are not in contact with the refrigerator and do not apply force to the refrigerator either, which avoids the damage to the refrigerator incurredby the traditional mode of ice removal through scraping or heating, and can guarantee the service life of the refrigerator.

The invention relates to a biological composite enzyme of a pretreatment refining process for cotton fabric dyeing and finishing, and a pretreatment refining process thereof. The biological compositeenzyme is formed by mixing 23.8-27.3 wt% of alpha-amylase, 54.5-71.4 wt% of pectinase and 4.8-18.2 wt% of cellulase.
