Description
Technical field
The utility model relates to a kind of centrifuge, relates in particular to a kind of high-efficiency sedimentation centrifuge for medical production and processing.
Background technology
Centrifuge is to utilize centrifugal force, the machinery of each component in the mixture of separating liquid and solid particle or liquid and liquid.Sedimentation centrifuge is mainly used in the solid particle in the suspension and liquid are separated; It also can be used for getting rid of the liquid in the wet solid, for example dries wet clothes with washing machine; Special hypervelocity channel separator is the admixture of gas of separable different densities also; Utilize the different characteristics of solid particle sinking speed in liquid of different densities or granularity, some sedimentation centrifuges also can carry out classification by density or granularity to solid particle.Existing pharmaceutical sedimentation centrifuge is deposited some shortcomings, and the separating effect of centrifuge is relevant with the rotating speed of rotary drum, and rotating speed is higher, and then separating effect is better, so that manufacturing cost and technical difficulty are also just higher.If do not improve the rotary drum rotating speed, existing centrifuge wants to keep preferably that separating effect is very difficult, and at present, most of centrifuges only can be processed 1/3 flow, and separative efficiency is very poor, and other 2/3 fluid that does not obtain processing can only reenter the circulatory system.In a word, how further improving the separating effect of centrifuge and treating capacity is the current major issue that solves of needing.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of new and effective sedimentation centrifuge is provided.
For achieving the above object, technical solution of the present utility model is: new and effective sedimentation centrifuge, comprise rotary drum, auger conveyor, differential mechanism, transmission device, casing and support, described auger conveyor is inboard at rotary drum, described differential mechanism is connection for transmission device and rotary drum respectively, support connects rotary drum, and support is connected with casing, it is characterized in that: the feed accelerator is installed in the described auger conveyor.
Further, described feed accelerator is cast by 4 blades and base plate one.
Further, the shape of described leaf cross-section is designed to 2 sections camber lines, the 1st section camber line employing near the auger conveyor center line in described 2 sections camber lines is crooked towards the rear of accelerator direction of rotation, and the 2nd section camber line then adopts towards the place ahead of accelerator direction of rotation crooked in described 2 sections camber lines.
Further, have wider cannelure on the described auger conveyor.
Operation principle of the present utility model is: by motor connected with differential assembly, differential mechanism is connection for transmission screw drum and outer drum respectively, suspension is by in the feed pipe input screw drum, under centrifugal effect, form certain solid-phase layer, conveyer passes solid phase to rotary drum cone section dry section, screw drum is under the effect of differential mechanism, form a constant leading speed discrepancy than outer drum, solid phase pushed by rotation be transported to slag-drip opening and discharge, liquid phase is discharged by the outer drum fluid port, in the feed pipe input screw drum, after rapid subsidence under the effect that speedup centrifugal sedimentation is filtered, be discharged to outer drum by each filter chamber's nozzle.
The beneficial effects of the utility model are: (1) under the same conditions, solid concentration is high in the deslagging of Novel centrifuge, liquid content is few; And all there is in various degree running pulp in traditional centrifuge at slag-drip opening.Show that Novel centrifuge has the ability of solid phase in the stronger removing liquid, also have larger treating capacity simultaneously.
(2) in the Novel centrifuge auger conveyor feed accelerator has been installed, the speed that this feed accelerator can accelerating liquid can make again the suffered moment of torsion of auger conveyor as far as possible little.
(3) because the feed accelerator is installed in the auger conveyor, and the blade of accelerator can not produce disturbance to liquid pool, can not limit the degree of depth of liquid pool in the rotary drum yet.
(4) the feed accelerator can play accelerated motion to liquid, makes solid phase particles can be deposited to rapidly the rotary drum inner surface, can improve the centrifuge solid-liquid separation effect.
(5) the wider cannelure of opening on the auger conveyor can make the diffusion of liquid large tracts of land, has greatly reduced the turbulent flow in traditional centrifuge feed zone.
Description of drawings
Fig. 1 is the structural representation of auger conveyor.
Fig. 2 is the front view of feed accelerator.
Fig. 3 is the left view of feed accelerator.
In the accompanying drawing, 1-feed accelerator, 2-cannelure, 3-auger conveyor, 4-blade, 5-base plate.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
A kind of high-efficiency sedimentation centrifuge comprises rotary drum, auger conveyor, differential mechanism, transmission device, casing and support, and wherein: auger conveyor 3 is inboard at rotary drum, and differential mechanism is connection for transmission device and rotary drum respectively, and support connects rotary drum, and support is connected with casing.
Suspension is inputted the feed chamber of auger conveyor 3 continuously through feed pipe, again in discharging opening enters the rotary drum of High Rotation Speed.Under the effect of centrifugal force, so that massive solid particle is separated from suspension, and be forced to founder on the drum inner wall, place in the same way differential speed rotation of rotary drum interior auger conveyor 3 and rotary drum, conveyer passes solid phase to rotary drum cone section dry section, slag-drip opening by drum head is released, and the liquid after the purification forms an interior ring that is called tank or pond, discharges continuously the adjustable ring-like baffle plate spout hole on being contained in rotary drum.Baffle plate can the balancing tank the degree of depth, the darker clean-up effect of the degree of depth is better, the solid phase that depth as shallow is discharged is dry.
Such as Fig. 1, Fig. 2, shown in Figure 3, in the auger conveyor 3 of Novel centrifuge feed accelerator 1 is installed, feed accelerator 1 is cast by 4 blades 4 and base plate 5 one, the shape of blade 4 cross sections is designed to 2 sections camber lines, the 1st section camber line employing near auger conveyor 3 center lines is crooked towards the rear of accelerator direction of rotation, to reduce moment of torsion; The 2nd section camber line then adopts towards the place ahead of accelerator direction of rotation crooked, to increase liquid outlet speed.Simultaneously, have several wider cannelures 2 on the auger conveyor 3, be convenient to liquid and pass through smoothly.Novel centrifuge changes the high speed axially-movable of feed mud into by 4 of feed accelerator 3 long and wide blades 4 and accelerates radial motion and non-turbulization, and solid phase particles is accelerated and is deposited on the drum inner wall, greatly to improve the separating effect of centrifuge.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or simple transformation of utilizing the utility model specification and accompanying drawing content to do includes in scope of patent protection of the present utility model.
