Detailed Description

A centrifuge as shown in fig. 1, which comprises a centrifuge housing 1, a centrifuge top cover 2, a centrifuge drum 3 disposed inside the centrifuge housing, a gear shaft 4, a scraper 5, a linear driving mechanism 6, a feeding pipe 7, a discharging pipe 8 and a discharging pipe 9, wherein the gear shaft 4 is disposed on the top of the centrifuge drum 3 and penetrates through the centrifuge top cover 2 for connecting a motor to drive the centrifuge drum 3 to rotate, a plurality of liquid outlet holes 303 uniformly arranged are formed on the inner side wall of the centrifuge drum 3, the liquid outlet holes are covered with a filter layer 301, the scraper 5 is disposed inside the centrifuge drum 3 and located in a space surrounded by the filter layer 301, the scraper 5 is disc-shaped and in circumferential contact with the filter layer 301, and the area of the scraper 5 is equal to the cross-sectional area of the space surrounded by the filter layer 301, the linear driving device is connected with the scraper 5 for driving the scraper 5 to be longitudinally straight in the space surrounded by the filter layer 301 The centrifugal machine is characterized in that the centrifugal machine moves in a reciprocating mode, the feeding pipe 7 conducts the interior of the centrifugal rotary drum 3 and the exterior of the centrifugal machine shell 1 for adding materials, and the discharging pipe 8 and the liquid outlet pipe 9 are respectively provided with an electromagnetic valve 10.

Set up one in centrifugal rotary drum 3 filter layer 301 around the space and surround the same and circumference contact's of space sectional area scraper 5 with filter layer 301, after the centrifugation is accomplished (after solid-liquid separation promptly), scraper 5 is through sharp actuating mechanism 6 along the vertical downstream of filter layer 301, scrape the solid of laminating on the filter layer 301 and fall, when moving to filter layer 301 bottom, the solid is scraped and is accomplished, is drawn back to the inside top surface of centrifugal rotary drum 3 by sharp actuating mechanism 6 again, and the discharge gate is unified to the solid is discharged, and liquid thing passes through the liquid outlet and discharges. The utility model discloses the corruption of remaining solid object on the filter layer 301 to filter layer 301 and the pollution to new centrifuge of treating have been reduced.

Because the centrifugal drum 3 rotates at a high speed during centrifugation, the filter layer 301 of the centrifugal drum is in circumferential contact with the scraper 5, so that the filter layer 301 is worn by the scraper 5, and the filtration effect is further affected, the centrifugal drum 3 of the embodiment further includes an accommodating cavity 302, the accommodating cavity 302 is disposed at the top of the centrifugal drum 3, is communicated with the space surrounded by the filter layer 301, has a cavity cross-sectional area larger than that of the space surrounded by the filter layer 301, is used for accommodating the scraper 5 therein, and the gear shaft 4 is connected with the accommodating cavity 302. The scraper 5 is accommodated in the accommodating cavity 302 by arranging the accommodating cavity with the cross sectional area of the cavity larger than the cross sectional area of the filter layer 301 surrounding the space, the scraper 5 is accommodated in the accommodating cavity 302 in the centrifugal process, after the centrifugation is completed, the scraper 5 enters the space surrounded by the filter layer 301 (namely, the centrifugal area of the centrifugal filter) along with the linear driving mechanism 6, solid matters attached to the filter layer 301 are scraped from top to bottom, and the scraper 5 is pulled back to the accommodating cavity 302 by the linear driving mechanism 6 when moving to the bottom of the filter layer 301. When using, gear shaft 4 passes through motor drive and drives the centrifugation and change and roll the centrifugation, and centrifugation back scraper 5 is driven by straight line actuating mechanism 6 and is entered into filter layer 301 from holding chamber 302 and carry out the operation, and the back is accomplished in the operation, opens solenoid valve 10, and solid material is discharged from the discharge gate, and liquid material is discharged from the liquid outlet.

More specifically, the gear shaft 4 is axially hollow and is communicated with the accommodating cavity 302, the linear driving mechanism 6 includes a hydraulic machine 601 arranged on the top cover 2 of the centrifugal machine, a hydraulic rod of the hydraulic machine 601 is connected with the scraper 5 through a hollow part of the gear shaft 4 and is used for driving the scraper 5 to do longitudinal linear reciprocating motion along the filter layer 301, and one end of the discharge pipe 8 is communicated with a space surrounded by the filter layer 301 through the hollow part of the gear shaft 4.
