A kind of starch separating machine
Technical field:
The invention belongs to mechanical field, relate to a kind of machinery of separating starch, particularly a kind of starch separating machine that has cleaned by ultrasonic vibration.
Technical background:
The starch separating machine that uses generally is divided at present: shaft screen (sieve) that reciprocating type plansifter (sieve), band hairbrush rotate and bent sieve, they have a common drawback is exactly that starch separates unclean, still surplus a part of starch is stayed granulated slag particulate core, this is that vibrational frequency low (1-20HZ) is determined owing to above three kinds of separation machinery washing times short (only through once washing).
The objective of the invention is to provide a kind of washing time long, the vibrational frequency height, starch separates clean starch separating machine.
Summary of the invention:
The overanxious shaft screen of upper level, cleaned by ultrasonic vibration tube, cascade filtration shaft screen are installed in series on an axle.This major axis is a tubular shaft, and an end has water inlet pipe and oil (water) envelope, and the other end has the end cap cap; On the tubular shaft corresponding, bore several little water holes with overanxious shaft screen of one-level and cascade filtration shaft screen, so as when the axle rotation work on the granulated slag in shaft screen the centrifugal rinse water that sprays equably come.The helical spring type setting gauge that cylindrical skeleton is arranged in the middle of a side of brush holder is equipped with so that the screw inclined plane of spring can promote granulated slag and evenly advances when rotating, can not assembled too much, bursts sieving the end.Because the male helicoid of spring does not have sharp point, so can not scratch the sieve end.The diameter of ultrasonic vibration wash bowl is greater than the diameter of shaft screen shell, so that at bottom dress ultrasonic generator vibration plate with as ultra-sonic oscillation chamber and installation spiral stirrer; The teeter column also can store granulated slag and the water after one-level is filtered, it is in the scavenging solution of medium that ultrasonic generator converts by transverter that the high frequency mechanical oscillation propagates into water through vibration plate to, ultrasonic wave in water density interphase ground to previous irradiation, make the ten hundreds of micro-small bubbles of generation in the water body, these small bubbles form at the negative pressuren zone that the ultrasonic wave longitudinal propagation becomes, growth, and at the zone of positive pressure rapid closing, in the process of this being referred to as " cavitation " effect, be negative pressure during bubble formation, can form the instantaneous pressure that surpasses 1000 air pressure when closed, time continuously produce high pressure p.s. 2.8 ten thousand-120,000 and constantly impact granulated slag surface and inner starch granules just as a succession of little " blast ", starch granules is constantly peeled off rapidly from granulated slag (cavernous body reticulated structure) core position, outstanding being dissolved in the water, thus reach the purpose of cleaning the granulated slag internal starch; The secondary shaft screen is isolated outstanding solution of starch and the granulated slag after ultrasonic cleaning.
The present invention is simple in structure, and trommel screen and ultrasonic cleaning vibration plate all are proven technique, and the present invention is the two grafting together, and institute is so that implement.
Concrete structure of the present invention is provided by following examples.
Description of drawings:
Accompanying drawing is the sectional structure synoptic diagram of the starch separating machine that proposes of the present invention.
Describe concrete structure of the present invention and working condition in detail below in conjunction with accompanying drawing:
1, axle water inlet pipe and oil (water) envelope; 2, tubular shaft; 3, belt pulley; 4, bearing; 5, feed-pipe; , 6 shaft screen shells; 7, the screen frame and the sieve end; 8, helical spring type setting gauge; 9, hairbrush; 10, grout outlet; 11, ultrasonic cleaning chamber; 12, ultrasonic wave vibration plate; 13, spiral stirrer; 14, water inlet pipe; 15, tubular shaft water hole; 16, slag notch; 17, tubular shaft end cap; 18, secondary screen drum.
Embodiment:
Motor drives belt pulley 3 rotates, starch mixture after the pulverizing enters in the cylinder 7 from feed-pipe 5, hairbrush extruding through rotating, filter to isolate starch fluid and granulated slag through the sieve end 7, clear water enters in the tubular shaft 2 of rotation through the sealing of oil (water) envelope from axle water inlet pipe 1, continue the drip washing granulated slag on the granulated slag by tubular shaft water hole 15 centrifugal evenly being sprayed on, granulated slag is dialled in the ultrasonic cleaning chamber 11 uniformly by helical spring type setting gauge 8, water inlet pipe 14 is put into clear water, ultrasonic wave vibration plate 12 produces HF oscillation (more than 20,000 times) starch wash that is retained in granulated slag core place is come out, push separating starch liquid and granulated slag in the secondary shaft screen 18 through spiral stirrer 13 stirrings, flow out from grout outlet 10 and slag notch 16 respectively.
Though the present invention is simple, can tell the starch that carries over from having only really through the granulated slag core position cleaning screen after once sieving.
