The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As Fig. 2, Fig. 3 and shown in Figure 4, bowl of the present invention, comprise: the rotary drum 2 and rotary drum head 1 of main shaft 5 be used for to be installed, this rotary drum 2 comprises: the segregation section 21 that diameter is bigger is rotary drum body supporting section 23 less with diameter, that link to each other with rotary drum head 1 and is connected segregation section 21 and at the bottom of the conical section 22 of supporting section 23 is rotary drum, the segregation section 21 of described rotary drum and the intersection of conical section 22 are provided with the discharge opeing tube 25 of outside protrusion, between the segregation section 21 of discharge opeing tube 25 and rotary drum 2 along circumferentially being provided with several evenly outages 27 of layouts; In the present embodiment, described outage 27 is oblique layout, and the angle between the center line of outage 27 and the center line of rotary drum is at (this angle is usually between 20～40 degree) between 15～50 degree; The lower edge of described discharge opeing tube 25 is provided with the liquid barrier 26 of ring-type, makes discharge opeing tube 25 form liquid storage chamber 15.
Certainly, discharge opeing tube in the bowl of the present invention also can be arranged on the segregation section 21 of rotary drum and the intersection of the lip ring 16 at segregation section 21 tops that are positioned at rotary drum except the intersection of the segregation section 21 that is arranged on rotary drum and conical section 22.
As shown in Figure 5, link-suspended basket centrifuge, its structure comprises: 3-foot support 13, be movably arranged on the main shaft 5 on the support 13, above-mentioned rotary drum is arranged on the main shaft 5 by its rotary drum head 1, also be provided with the uncovered casing 14 that makes progress on the support 13, the top of casing 14 is provided with renovates 6, renovates and is equipped with distribution device 8 and doctor blade device 7 on 6, the barrel of rotary drum 2 is provided with filter screen 3 and blocks bagging apparatus 9, and liquid storage chamber 15 is provided with the discharging tube 10 of outwards drawing.
As shown in Figure 6, flat centrifuge, its structure comprises: flat support 13, be movably arranged on the main shaft 5 on the support 13, above-mentioned rotary drum is arranged on the main shaft 5 by its rotary drum head 1, also be provided with the uncovered casing 14 that makes progress on the support 13, the top of casing 14 is provided with renovates 6, renovates and is equipped with distribution device 8 and doctor blade device 7 on 6, the barrel of rotary drum 2 is provided with filter screen 3 and blocks bagging apparatus 9, and liquid storage chamber 15 is provided with the discharging tube 10 of outwards drawing.
The operation principle that vertical centrifugal machines such as the link-suspended basket centrifuge of rotary drum of the present invention, flat centrifuge are installed is: rotary drum rotates with predefined suitable rotating speed, slip obtains centrifugal force after entering rotary drum, the barrel of trend rotary drum 2, the centrifugal force that produces when the material work rotates at a high speed in the rotary drum drive rotary drum of rotation separates two kinds of density differences and immiscible liquid with the suspension of solid particle.Because this vertical centrifugal machine has increased the liquid storage chamber 15 that is made of discharge opeing tube 25 and liquid barrier 26 with respect to common vertical centrifugal machine, during filtration, filter cloth, filter screen 3 and the outage 27 of filtrate through blocking bagging apparatus 9 flows into liquid storage chamber 15, drawn by the filtrate that discharging tube 10 is indoor with liquid storage.During practical application, discharging tube 10 is controlled the liquid level in the liquid storage chamber 15 by the position of its mouth of pipe of driving mechanisms control.
