Description

Centrifugal machine

This centrifuge belongs to the centrifuge class in the separation machinery.

The centrifuge that prior art provided, major part are the automatic continuous centrifuges of no device for discharging, and filter residue overcomes friction with filter screen by the centrifugal force that itself obtains in taper drum, move to the big end of rotary drum along the drum wall, and filter residue draws off voluntarily.It is simple in structure, and cost is low, and power is little.But have following weak point: bowl is a tower structure, the lining net laid is to be welded on one's body the framework drum by butt joint after being cut into some fanning strips and point in the framework of welding, butt weld place between the big small end fanning strip of lining net is welded with lock seaming iron respectively, processed complex; The centrifugal dewatering process is only carried out in the rotary drum (cone-element) in the above, because the rotary drum cone angle is excessive, to the concentration and the big minor swing sensitivity of solid particle size of suspension; Rotary disk passes through the Bolt Connection transferring power with drum base pressure ring, and the centrifugal dewatering effect can not divided in whole drum bottom; Veil is online at lining by some fanning strip lapped layups, relies on the drum end and damage by pressure concavo-convex and compresses, and service life is short, damages the bad replacing in back; Base portion does not have cooling device, and easily heating forms the calorie resistance.

This novel purpose is to provide a kind of principle that still adopts centrifugation to take off the automatic continuous discharge of liquid, the advantage that possesses existing centrifugal unloader centrifuge, overcome its weak point, adopt the frame-type rotary drum to lay monoblock type lining net, veil, make the bulging end also have the liquid of taking off ability, base is provided with the centrifuge of cooling device.

This novel technical solution in conjunction with the accompanying drawings 1, the centrifuge structure schematic diagram, Fig. 2, drum bottom structure schematic diagram is described further.This centrifuge as shown in Figure 1, by dress cylindrical shape water jacket 22 in spoke-like support 23 its central hubs, looping cooling water cavity 21, dress cooling water pipe 20 on the wheel hub wall, pass wheel hub wall and on water jacket, adorn lubricating oil pipe 18, adorn several groups of bearings 16 in the water jacket 22, back shaft 19, on the wheel hub, with end cap seal part and bolt axle 19 is located below, bolt dress cylindrical shape Water collecting tube 7 above the wheel hub, its underpart lowest part sets out the mouth of a river 17, the ends 12, roused with key 15 dress alms bowl shapes in axle 19 upper ends, as shown in Figure 2, offer the apopore 29 that many seniority among brothers and sisters row are arranged on the drum diapire, interior back boxing monoblock type lining net 13, spindle nose fastens with bolt of cover with the drum end and uses 14 cappings of reed large bamboo hat with a conical crown and broad brim shape distributing device again, the drum end 12 is suitable for reading to have ring flange and back taper by upper flange plate 3, lower flange 10, the taper framework of many uniform rib 4 weldering systems, the big end rotary drum 5 that interior spot welding monoblock type lining net 13 is formed, link with bolt, on, the lower flange inboard, drum end inner underside is offered the rectangle annular groove, with square-section annular spring clip 2,11,28 embeddings clip monoblock type veil 6, upper flange plate 3 covers the suitable for reading of Water collecting tube 7, bolt dress cylindrical housing 8 above the outer rim of support 23, suitable for reading have a disc loam cake 1, suspention feed pipe 9 in the lid medium pore, the spoke downside dress brake support 25 of support 23 links belt brake 24, contain and to be contained in the face of cylinder that axle 19 lower ends and big pulley concial disk are one, bolt dress support of motor 27 on the support 23 wheel rim lateral surfaces, dress motor 26 it on, the little pulley concial disk of motor shaft end key dress by V belt connect with pulley concial disk greatly form.

The industry operation of this centrifuge.Connect the power initiation motor, make axle 19 by transmission system, after driving the drum end 12 and end rotary drum 5 reaching rated speed greatly, filtrate is added from the feed pipe 9 of suspention, by distributing device 14 uniform distributions, filtrate is from veil 6, lining net 13, drum end apopore 29 throws away to form and takes off liquid for the first time, because the centrifugal action filtrate is along moving on the drum wall, enter big end rotary drum 5, centrifugal force constantly increases, and remaining filtrate is from veil in the filtrate, the lining net is discharged rotary drum, form and take off liquid for the second time, collected through delivery port 17 discharge centrifuges by Water collecting tube, filter residue is suitable for reading from big end rotary drum 5, be splashed to the annular chamber between Water collecting tube and the shell 8, drain into collection slag bath under the centrifuge from the spoke-like support.During the centrifuge operate as normal, lubricating system, cooling system also enters normal operating conditions, works as shutdown, or during fault repair, cuts off the electricity supply, and handles brake gear 24, and rotary drum is stopped operating rapidly.

The advantage of this centrifuge has: adopt monoblock type lining net, simplified manufacturing process and reduced soldered, reduce welding stress, strengthen drum strength, save lock seaming iron, pressure ring, alleviate centrifuge weight thereby reach rotary disk, centrifugal dewatering can form secondary and take off liquid and improved separating effect from the drum end; Veil is that monoblock type is fixed on rotary drum and rouses at the end with clamp, and it is convenient to change, and the life-span is long; Be provided with cooling and lubricating and brakes, power consumption is few, and is safe and reliable to operation.

This centrifuge can extensively be adapted to brewage, the solid, liquid in chemical industry, light industry, medicine, food service industry and the environmental protection industry (epi) separates.
