Centrifugal slag slurry bolter
(1) technical field
The utility model relates to a kind of starch process equipment, particularly relates to a kind of centrifugal slag slurry bolter, is particularly useful for starch and separating that slag is starched in the starch production such as wheat, potato class.
(2) background technology
At present, wheat, potato starch production are in the fast-developing phase at home, and existing starch and slag slurry separation equipment generally adopt pressure curved sieve; Starch thin pulp after wheat, the fragmentation of potato class is from top to bottom injected the arc compass screen surface by the starch pump pressurization along pressure curved sieve internal tangent direction, the emulsus starch size can be by screen filtration to sieve down, thicker, fibrous slag slurry then can't pass sieve screen apertures, so just can realize slag starched and separate with starch slurry.By its structure and principle as can be known; adopt this kind method slag to wash and starch to wash insufficient, still contain the starch of a great deal of in the slag slurry after the separation, its disposal ability is also limited; foam is more in the starch slurry of separating, and can not satisfy the needs of scale production process and producer.
(3) summary of the invention
That the purpose of this utility model designs at existing problem in the above-mentioned prior art just is a kind of rational in infrastructure, treating capacity big, the starch washing separates fully, high efficiency, centrifugal slag slurry bolter that power configuration is low.
Key of the present utility model is to replace the arc compass screen surface with the horizontal cone compass screen surface, centrifugal force with rotation generation at a high speed replaces pressure, be equipped with suitable positive and negative washings mechanism again, washing is abundant to reach, the purpose of high throughput, in the connection of bearing housing assembly, also be different from traditional fixed structure, make every effort to simple and direct practicality.
The purpose of this utility model realizes by following scheme: this centrifugal slag slurry bolter comprises frame, housing, be arranged on the basket mechanism in the housing, feed pipe, flushing water system and the power set that are used to drive basket mechanism, wherein: basket is the pyramidal structure of horizontal positioned, the necking end of basket combines by connecting piece and power output shaft and with its rotation, central feed tube is arranged on the basket center, its discharging opening is over against the necking end center of basket, water tank is installed on the central feed tube that is arranged in the basket cavity by connector, evenly be furnished with a plurality of nozzles on the tank outer wall, in housing, be positioned at basket flared end place and be provided with a dividing plate, housing is divided into undersize material chamber and oversize material chamber.
In the utility model, be provided with the evenly distributed rushed back water device that nozzle is arranged on its parallel with the compass screen surface tapering on the top of basket mechanism; Can regularly carry out backwash, remove the thin slag of compass screen surface absorption, avoid compass screen surface to stop up screen cloth.Actuating unit comprises motor, belt drive system and bearing housing assembly, the power intake of bearing housing is by frame support, the other end supports by the taper surface flange in the bottom on the housing, the basket connecting piece is installed in the output axle head of bearing housing assembly by key and center holding screw, and basket is fixed on the basket connecting piece by the flange of its necking end.
Be provided with the sub-material guiding mechanism in the central feed tube of the present utility model, the sub-material guiding mechanism is to constitute by being installed on the adjusting rod that its top in the central feed tube is provided with conical disc, and adjusting rod can be by displacement before and after guiding mechanism is in feed pipe, the port of export at central feed tube also is provided with a bowl seal circle, can guarantee that starch slurry enters the basket awl end equably.
For guaranteeing that the flushing water in the water tank evenly and closely is ejected on the compass screen surface, water tank is a pyramidal structure, and its tapering is identical with the tapering of taper basket.
Operation principle of the present utility model is: potato class after the fragmentation or wheaten starch slurry enter the tapered basket of level bottom by feeding mechanism.The tapered basket of level is installed on the machine spindle, does rotation at a high speed under by the drive of mechanism's transferring power such as motor, drive disk assembly, bearing housing assembly.Starch size evenly enters on the compass screen surface of the tapered basket of level bottom by feeding distribution mechanism, under the double action of gravity and centrifugal force, slurry is made circular motion along compass screen surface and is also moved to the basket edge simultaneously, under the spray of water tank assembly and rushed back system, tiny starch granules sees through the sieve screen apertures discharge in the moving process, by sieve defoaming pump discharge down.Bigger starch granules and fiber can not see through screen cloth, fall to the slag storehouse gradually along compass screen surface, are drained by pulp pump.Potato slag and starch size constantly are subjected to the flushing of flushing water in the process that moves to the edge, can remove the free starch of absorption in the slurry that removes slag to greatest extent; In addition, under recoil tube (the rushed back water device) effect at the tapered compass screen surface of level back, but the thin slag of place to go compass screen surface absorption is avoided the obstruction of compass screen surface effectively, guarantees the normal operation of equipment;
In the middle of housing assembly, dividing plate is arranged, housing is divided into oversize material chamber, undersize material chamber two parts.Charging mouth of pipe opening is over against the bottom of the tapered basket of level, and the exit is furnished with distributor gear (being sub-material guiding mechanism and butterfly sealing ring), enters the basket awl end equably to guarantee starch slurry.Tapered basket is made up of sieve nest, compass screen surface, and it is conical that the skeleton external form of sieve nest is, uniform orthohexagonal hole on the conical surface; Compass screen surface evenly, closely is fixed on the sieve nest inner face by nine fan-shaped compositions by method for welding.In the design of bearing housing assembly, also be different from traditional bearings at both ends seat supports structure, the power intake of bearing housing is by stent support, and the other end supports by tapered flange in the bottom on the housing assembly, has reached the purpose of simplified structure.
Owing to adopt above scheme, the fecula slurry is separated on the tapered compass screen surface of whole level and carries out, and has increased the screen work area, makes high throughput become possibility; The raising of efficient simultaneously makes the power configuration under the same terms obtain reduction.The uninterrupted flushing of flushing water also makes the slag slurry separate more thoroughly fully.
