Edit the principles and structure of this section
Disc separator is a vertical centrifuge drum mounted on the upper end of the vertical shaft, while the high-speed rotation of the gear driven by a motor with a set of nested together, dished parts inside the drum. - Disc discs and discs leaving a small gap between. suspension (or emulsion) from the center located at the drum feeding tube to join the drum. When the suspension (or emulsion) flow through the gap between the disc work principle
The solid particles (or droplets) to sink down in the centrifuge effect of sediment formation (or liquid layer) on the disc. Sediment from the disc and the disc along the sliding surface and accumulate in the largest diameter portion of the drum, the liquid after the separation discharged from a liquid outlet drum role of the disc is to shorten the solid particles (or droplets) settlement from the expansion of the settlement area of the drum, the drum due to the installation of the disc and greatly enhance the production capacity of the separation unit. accumulation of solids in the drum after separation drum machine downtime apart from the manual removal, or discharge from the drum in the case of non-stop through the slag agency disc separator can be done in two operations: Liquid - Solid separation (ie isolated background concentration of the suspension), called to clarify the operation; liquid - liquid separation (or liquid - liquid - solid) separation (ie separation of the emulsion), said separation operation.
Drum built with a stack of conical discs, emulsion separation and low concentration suspension of centrifuge components by centrifugal sedimentation method. Disc separator can be operated in a closed, high temperature, low temperature, pressure and vacuum conditions for extracting cream and juice, beer, animal and vegetable oils, transformer oil purification from milk and yeast extract concentration and serum from animal plasma, etc. isolated suspension (Fig. 1a), suspension by the central feed tube into the drum, the outer edge of the beam by the disc into the disc space flows from the edge of the disc. due to the centrifugal force, the solid particles with the liquid flow at the same time settling into the inner surface of each disc, the disc outer edge of the slide again and finally deposited onto the drum wall. has a clear liquid gathered to drum center direction, the overflow outlet or discharged to the heart pump. emulsion separation (Figure 1b), emulsion through the feed beam on the disc hole into each disc space, according to the density divided into heavy liquid and light liquid, heavy liquid inside the drum wall along the disk surface to flow toward the center of the light liquid flows through the overflow port and radial discharge pump respectively. Feed hole location should be. referred to herein as neutral layer at the junction of the heavy liquid layer and the light liquid layer, its radius formula
When where k is the heavy liquid and light liquid density ratio, R1 and R2 is the radius of the outlet of the heavy liquid and light liquid feed apertures respectively do not coincide with the neutral layer, light weight solutions or not pure liquid discharged , then you can change the weight of liquid or light liquid discharge outlet radius to adjust the position of neutral layer. Since the liquid inside the drum discs beam is divided into many thin layers, separated in thin beds, centrifugal sedimentation distance is very short, significantly improve the separation speed. higher disc separator separation factor of 4,000 to 10,000, and the amount due to multiple discs within the drum, significantly expanding the size of the settlement, high separation efficiency. Radial pump (Figure 1c) has a fixed stationary on the housing an impeller outer edge immersed in sync with the rotation of the drum layers were separated, the separated liquid by the impeller into the curved outer edge of the flow channel, the flow to the center of the drain pipe from the impeller The impeller rotational kinetic energy into static pressure of the liquid, the separated liquid discharged from the drum directly supplied to the 10 to 20 meters in height.
Artificial slagging disc separator
Department of intermittent operation. It is from the base, gear, drum and chassis and other components (Figure 2) is a vertical machine, the drum for the next-supporting outer drum near the main bearings 6 are arranged radially shock absorber spring (or rubber) thereof. drum gear helical gear overdrive usually taken, some take the belt drive. drum lid and the drum body by a threaded locking ring fastening and sealing . Circle leak-proof disc is conical, the half cone angle is greater than the friction angle of the solid particles and the disc surface, usually 30 ° ~ 45 °, the disc number from 50 to 180; the disc gap of 0.5 to 2 mm. After separation machine working for some time, increased sediment on the drum wall, separating liquid clarity decline, when the separated liquid clarity undesirable, stopping open the drum, the drum manual removal of sediment. This separation machine processing capacity can be up to 45 m 3 / h, adapted for processing a particle diameter of 0.001 to 0.1 mm, the solid concentration is less than 1% of the suspensions and emulsions.
Nozzle slagging disc separator
Continuous operation. The overall configuration of the artificial slagging disc separator is similar, but the drum (Fig. 3) double-lumen cone can sediment from the compression effect, increase sediment concentration within the largest drum diameter 900 mm. Drum circumferential edge of a slurry of sediment discharge nozzle 2 to 24, nozzle diameter of 0.5 to 3.2 mm nozzle aperture according to the number and the nature of the suspension, the degree of enrichment and processing capacity is determined by the sediment flow rate of the nozzle is disc separator
Large nozzle with a wear-resistant material such as tungsten carbide, boron carbide, alumina and the like. Sediment concentration part to improve the slag, which also will be discharged from the separator back to the drum recycling structure. Sediment solid phase Solid phase concentration than the feed concentration increased by 5 to 20 times the amount of processing machines such separation of up 300 m 3 / h, suitable for the treatment of solid particles having a diameter of 0.1 to 100 microns, the solid phase concentration is usually less than 10% ( the largest up to 25%) of the suspension.
Shutter slagging disc separator
Use ring shutter opening and closing intermittently slagging slagging mouth, also known as automatic slagging disc separator overall structure and artificial slagging disc separator similar characteristics is the drum (Fig. 4) has a valve slagging means, without stopping removing sediment inside the drum. During operation, the drum center feeding tube added to the suspension were separated following the shutter seal water pressure is greater than the total suspension of the role of the total pressure in the top of the shutter, the shutter position on, when you close the tap outlet (Figure left isolated state). slag, stop feeding the bottom of the drum is added by operating water disc separator
, Open the drum peripheral sealing water pressure relief valve; after opening the tap outlet (Figure right of the state) to drain the sediment and the liquid inside the drum; sealing water is discharged; the role of the drum suspension valve by the pressure of rapid decline. stop the water supply operation, the pressure relief valve is closed, sealing water pressure, valve closed slagging rise, to complete a work cycle automatic control valve slagging methods are:. ① time relay with a predetermined operating cycle control slagging; ② monitor with photocell control slag separation liquid clarity; ③ according to the degree of sediment accumulation within the drum, the pressure signal or the signal control slagging slagging slag surface time is generally 1 to 2 seconds partial slagging drum can. controlling slagging shorter time, only a portion of the inner drum sediment discharge, and not discharged liquid, without stopping when the slag feed, continuous separation, increased processing capability. This separation machine maximum capacity of up to 60 m 3 / h, suitable for the treatment of solid particle diameter of 0.001 to 0.5 mm, the solid-liquid phase density difference greater than 0.01 kg / dm3 solid concentration of less than 10% of suspensions and emulsions.
