Description
Technical field
The present invention relates to sedimentation centrifuge field, specifically belong to the synchronous self-priming apparatus of a kind of horizontal spiral discharge sedimentation centrifuge link-type.
Background technology
Current sedimentation centrifuge structural principle, see Fig. 1:
1, material enters in spiral 2 through feed pipe 1, enter in rotary drum 4 by spiral 2 discharging opening, material in the rotary drum 4 of High Rotation Speed through centrifugal sedimentation, the clear liquid of clarification forms centrifugal hydraulic pressure in the rotary drum 4 of High Rotation Speed, and the clear liquid clarified under the effect of centrifugal hydraulic pressure overflows rotary drum through overflow plate 6 and overflow plate flange 5.Regulate by changing overflow plate 6 after regulating sedimentation liquid tank depth H to shut down, thus reduce the operating efficiency of centrifuge.
2, when shutting down, centrifuge when rotating speed drops to certain rotating speed, because rotating speed is low to enough centrifugal force cannot be provided to make the Fluid tank depth remained in rotary drum 4 be that the clear liquid of H forms uniform pendular ring.Thus causing pendular ring H and rotary drum 4 bias, the eccentric dynamic loading that eccentric clear liquid is formed and centrifuge intrinsic frequency form resonance and cause centrifuge to vibrate very fast rising.Consequent resonance will cause the damage of centrifuge machine components and cause potential safety hazard to the person.
During the food material such as horizontal spiral discharge sedimentation centrifuge protein isolate 3, by overflow plate 6 overflow, cleaning can Liquid Residue tank depth be also the residual cleaning feed liquid of H in rotary drum after shutting down, and residual albumen feed liquid can cause spoilage problems, thus does not meet GMP requirement.
4, when material concentration fluctuates; in order to meet separating effect needs regulator solution tank depth H to eliminate the impact of material concentration fluctuation on separating effect; now must shut down and open case pull down overflow plate 6 and change the overflow plate 6 of corresponding Fluid tank depth H, this just needs the overflow plate 6 processing many groups of various Fluid tank depth H.Because this increasing the working strength of workman and greatly reducing the operating efficiency of equipment.If the material be separated is toxic and volatile material, often uncaps and will cause air pollution and actual bodily harm be caused to workman.
The technical problem that original structure solves is as follows:
1, solve when being separated the materials such as food, pharmacy, biochemical industry class, the clear liquid routine after separation need be collected by main body outer casing, then discharges through liquid outlet and causes clear liquid and extraneous contact to cause the problem of secondary pollution; Reach the clear liquid after separation directly to be discharged in main body by link-type synchronous self-priming pump device, avoid the clear liquid after separation and extraneous contact causes secondary pollution.
2, solve when separation effumability poisonous and harmful material, because collecting the human injury that causes of clear liquid and atmosphere pollution conventionally by Open architecture; Reach and collect clear liquid when being separated volatile poisonous and harmful material by closed structure, avoid the injury of volatile poisonous and harmful material to human body and the pollution of air.
3, solve regulator solution tank depth H, need to shut down the problem changing overflow plate 6; Reach and do not shut down just energy regulator solution tank depth H, thus improve machine operation efficiency.
4, solve centrifuge when shutting down, produce eccentric dynamic loading because Fluid tank depth centrifugal force suffered by the clear liquid of H residual in rotary drum 4 cannot maintain its uniform annular liquid layer and centrifuge intrinsic frequency forms the technical barrier resonated; When reaching shutdown, corresponding clear liquid can not be remained in rotary drum 4, thus avoid the resonance problem causing centrifuge.
When 5, solving the material such as food, pharmacy, biochemical industry class, cleaning feed liquid after washing centrifuger, in rotary drum, can not be remained, thus avoid the problem that residual cleaning feed liquid causes going bad.
6, solve when material concentration fluctuates, need not shut down and uncap just can realize the adjustment of Fluid tank depth H to meet separating effect.Thus alleviate workman's working strength and substantially increase equipment operating efficiency.
In real production process, usually can run into various new problem.
