The utility model can realize the driving of the inner liner of the centrifuge to rotate only by driving the conductive column to rotate by a motor, so the required power motor has low power, low energy consumption, and is energy-saving and environmentally friendly.

[0031] The technical solution of the present utility model is described in detail below through specific embodiments.

[0034] The centrifuge housing 100 is arranged vertically on the top surface of the centrifuge pillar 410 and is located on the inner side of the electromagnetic force disk pillar 420. A plurality of groups of double rollers 110 in the same horizontal plane are installed on the inner upper part of the centrifuge housing 100. In some embodiments, the number of groups of double rollers 110 can be 2 groups, 3 groups, 4 groups, 5 groups, 6 groups, etc. Each group of double rollers 110 includes an upper roller 111 and a lower roller 112 arranged vertically. The axis of the upper roller 111 and the lower roller 112 is fixedly connected to the inner wall surface of the centrifuge housing 100, and the axis surfaces of the upper roller 111 and the lower roller 112 can roll around the axis.

[0035] The top of the centrifuge liner 200 is provided with a first ring piece 210 extending horizontally outward. The first ring piece 210 is a suspension piece of the centrifuge liner 200 and is inserted between the upper roller 111 and the lower roller 112 of the double roller 110. The lower roller 112 supports the first ring piece 210, and the upper roller 111 presses the first ring piece 210, so that the centrifuge liner 200 is suspended in the internal cavity of the centrifuge housing 100, and can rotate with the upper roller 111 and the lower roller 112 as rotating rollers.

[0036] The centrifuge inner container 200 is evenly provided with water outlet holes (not shown in the figure). The top of the centrifuge inner container 200 is lower than the top of the centrifuge outer shell 100.

[0037] The top of the centrifuge liner 200 is also provided with a support plate 220 extending horizontally inward. A plurality of magnet blocks 221 are installed on the support plate 220 at equal intervals, and the magnet blocks are permanent magnets.

[0038] The electromagnetic force disk 300 includes an inner ring body 310 and an outer ring body 320 arranged concentrically and a plurality of insulating hollow tubes 330 connecting the inner ring body 310 and the outer ring body 320. Specifically, the inner ring body 310 includes an intermittently powered component, and the intermittently powered component includes a hollow insulating sleeve 311, a conductive column 312, a clutch 313, a clutch plate 314, a bearing seat 315 and a motor 316.

[0039] The hollow insulating sleeve 311 is located at the center of the electromagnetic force disk 300, the conductive column 312 is vertically installed at the center of the inner cavity of the hollow insulating sleeve 311, the bearing seat 315 is installed on the upper surface of the hollow insulating sleeve 311, the motor 316 is installed on the bearing seat 315, and the power output end passes downward through the bearing seat 315 and the hollow insulating sleeve 311 to connect with the conductive column 312, driving the conductive column 312 to rotate forward or reverse. The motor 316 is a micro motor with low power and low energy consumption.

[0040] The number of the clutches 313 is more than 4, and in this embodiment, is 12. The clutches 313 are installed at equal intervals at the same height of the wall of the hollow insulating sleeve 311. The clutch 313 includes an upper contact plate and a lower contact plate.

[0041] The clutch plate 314 is a flat metal sheet with a certain width and length, one end of which is installed on the conductive column 312, and the other end is in contact with the clutch 313 or suspended in the air as the conductive column 312 rotates. When connected to the clutch 313, it is located between the upper contact plate and the lower contact plate of the clutch 313.

[0042] The outer ring body 320 includes an insulating outer ring body shell 321 and an electromagnetic block 322. The outer ring body shell 321 is connected to the hollow insulating sleeve 311 through an insulating hollow tube 330. The electromagnetic blocks 322 are evenly spaced in the outer ring body shell 321, and the distance between adjacent electromagnetic blocks 322 is the radial distance of the clutch width on the outer ring body shell 321. The number of the electromagnetic blocks 322 is the same as the number of the clutch 313. The clutch 313 is connected to the electromagnetic block 322 through a wire built into the insulating hollow tube 330. When the clutch 313 is connected to the clutch plate 314, the electromagnetic block 322 is energized and generates magnetic attraction.

[0043] The outer ring shell 321 of the electromagnetic force disk 300 is supported and fixed by the electromagnetic force disk support 420, so that the electromagnetic force disk 300 is suspended above the centrifuge liner 200, and the electromagnetic block 322 is located above the magnet block 221 on the centrifuge liner 200. The number of the clutch 313, the electromagnetic block 322 and the magnet block 221 corresponds to each other. When the conductive column 312 rotates under the drive of the motor 316 and the electromagnetic block 322 is energized to generate magnetic attraction, the electromagnetic block 322 attracts the magnet block 221, and the magnet block 221 rotates when the electromagnetic block 322 is alternately energized and de-energized, thereby driving the centrifuge liner 200 to rotate and realize centrifugal dehydration.

[0044] The inner diameter of the top of the centrifuge liner 200 is equal to the outer diameter of the outer ring body 320 of the electromagnetic force disk 300. A collecting hopper 700 is provided at the lower eaves of the centrifuge liner 200 for receiving the separated solid materials.

[0045] Preferably, the inner diameter of the centrifuge liner 200 gradually increases from the top to the bottom, that is, the diameter of the bottom end of the centrifuge liner 200 is larger than the diameter of the top end, so that the wall surface of the centrifuge liner 200 at any point is inclined inward, so that the solid material attached to the centrifuge liner 200 during the centrifugation process can fall off the centrifuge liner 200 under the action of gravity.

[0046] Preferably, the centrifuge housing 100 is provided with a plurality of pulse interface holes 120, each of which is provided with a pulser 130, and the pulser 130 is connected to a pulse compressed air pipe 140. The pulse interface holes 120 are arranged in a clockwise spiral from top to bottom on the centrifuge housing 100.

[0047] A filter drum 230 is closely attached to the inner wall of the centrifuge inner tank 200, and the inner side of the filter drum 230 has spirally distributed ribs (not shown in the figure), and the ribs are wedge-shaped structures, and the spiral direction and inclination angle of the ribs on the filter drum 230 are the same as the spiral direction and inclination angle of the pulse interface hole 120. The design of the filter drum 230 with ribs can intercept solids and liquids in the centrifugal process, and also facilitate the fall of solid materials attached to the filter drum 230.

[0048] That is, air pulses are provided to the solid materials attached to the filter screen drum 230 through the pulse interface hole 120 and the pulser 130, so that the filter screen drum 230 is vibrated, thereby facilitating the peeling and separation of the solid materials thereon.

[0049] The material attached to the filter drum 230 after centrifugation slides down from the filter drum 230 under the combined action of the impulse of the pulse compressed air, the inclined force of the ribs on the filter drum and the gravity of the solid material itself, and slides down to the lower eaves of the centrifuge inner tank 200. With the centrifugal force, it falls into the collecting hopper for discharge, thereby realizing automatic and continuous discharge of solid materials, enabling the magnetic levitation centrifuge to continuously feed and discharge, thereby improving the separation efficiency.

[0050] The distribution pipe 500 for the solid-liquid mixture to be separated extends from the bottom of the centrifuge inner tank, and is provided with distribution holes facing the centrifuge inner tank 200 for continuously feeding materials into the centrifuge to achieve continuous feeding.

[0051] Preferably, the middle part of the centrifuge liner 200 is provided with a second ring sheet 240 extending horizontally outward, which is an eaves for blocking the centrifugal mother liquor. A mother liquor water tank 250 is installed between the second ring sheet 240 and the centrifuge housing 100 for receiving the centrifugal mother liquor. A distribution pipe 500 for the material to be separated extends from the bottom of the centrifuge liner 200, and the distribution hole on it faces the centrifuge liner above the second ring sheet 240, so that the mother liquor after centrifugal separation falls into the mother liquor water tank 250, and the bottom of the mother liquor water tank 250 is connected to a mother liquor discharge pipe 260 for real-time discharge of the centrifugal mother liquor.

[0052] The bottom of the centrifuge liner 200 is provided with a third ring sheet 270 extending horizontally outward, which is an eaves for blocking the centrifugal rinsing wastewater. A rinsing water tank 280 is installed between the third ring sheet 270 and the centrifuge housing 100 for receiving rinsing water. A rinsing pipe 600 extends from the bottom of the centrifuge liner 200, and the water distribution holes on it face the centrifuge liner between the second ring sheet 250 and the third ring sheet 270, so that the rinsing water after rinsing falls into the rinsing water tank 280, and the bottom of the rinsing water tank 280 is connected to a rinsing water discharge pipe 290 for real-time discharge of rinsing water.

[0053] By designing the second circle sheet 240, the mother liquor tank 250, the third circle sheet 270 and the rinsing water tank 280, the centrifuged material is rinsed, thereby improving the purity of the solid material after centrifugal separation.

[0054] The use method or working principle of the above-mentioned magnetic suspension centrifuge is:

[0055] When the conductive column 312 rotates under the action of the motor 316, the clutch plate 314 on the conductive column 312 passes through the upper contact plates and lower contact plates of the multiple clutches 313, so that the upper contact plates and lower contact plates of the clutch 313 are energized. When energized, the corresponding electromagnetic block 322 is energized to generate a magnetic field, which generates a suction force on the corresponding magnet block 221. The conductive column 312 rotates clockwise, and the magnetic field suction force rotates in the clockwise direction, thereby causing the centrifuge liner 200 to rotate clockwise. The faster the speed of the conductive column 312, the faster the speed of the centrifuge liner 200. When the motor 316 is turned on and reversed, the magnetic field suction force rotates counterclockwise, which can stop the centrifuge or reverse the centrifuge liner.

[0056] When the magnetic suspension centrifuge is turned on, the material placed in the material distribution pipe 500 is subjected to the centrifugal force of rotation, and water is scattered from the filter drum 230, and the solid material is retained on the filter drum 230.

[0057] The pulser 130 is turned on in order from bottom to top, connected with the pulse compressed air pipe 140, and blows pulses to the holes of the centrifuge inner tank 200, so that the solid materials attached to the filter screen are loosened, and the loosened solid materials slide down. When the three forces of the pulse compressed air impact, the inclined force of the ribs on the filter drum and the gravity of the solid materials themselves are combined, the materials slide down on the filter drum 230, and when they slide to the lower eaves of the centrifuge inner tank 200, they are scattered with the centrifugal force, and the scattered materials are received in the collecting hopper 700 for discharge. That is, as the materials to be centrifuged and filtered are continuously placed, the solid materials after centrifugation continuously slide down, scatter, and are received, forming a continuous feeding and continuous discharging mode.

[0058] The magnetic suspension centrifuge of the utility model embodiment has the following advantages:

[0059] 1. Through the design of the electromagnetic force disk suspended above the centrifuge liner, the motor only drives the conductive column to rotate, and uses the magnetic attraction to drive the centrifuge liner to rotate, which effectively reduces the driving power required by the power motor, reduces energy consumption, and saves energy and is environmentally friendly.

[0060] 2. Through the design of the pulser on the centrifuge shell, the air pulse is used to discharge the material, which is safe and convenient, and realizes continuous feeding and continuous discharging.

[0061] 3. Through the design of the second circle sheet, mother liquor tank, third circle sheet and rinse water tank, the solid material is rinsed, thereby improving the purity of the solid material after separation.

[0062] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
