Description

Grain is except stone desanding jigging machine

Technical field

The invention belongs to Cereals Processing Machines, particularly a kind of grain to food such as corn, wheat, soybean, peanut and the deep processings of sugar wine essence potato class removes stone desanding jigging machine.

Background technology

At present the domestic and even whole world various food processings and sugar, alcohol intermediate item except stone equipment.Substantially be all the self-chambering eddy flow paving stone desanding device that makes water rush chute and utilize water conservancy rotational flow sorting theory to make, the low desanding effect of this serial equipment efficiency is bad.Take corn deep processing as example: only can remove in corn 16.67% stone and impurity, also contain a large amount of corns in the stone that goes out and impurity and account for 2.9% simultaneously.Due to residual stone and impurity, subsequent production equipment is caused to very large impact.First in equipment, to add second to remove stone equipment and carry out again removing stone, due to not thorough except stone, production equipment be damaged in addition, increase the wearing and tearing of equipment, reduce the service life of equipment.Increase maintenance cost and the maintenance cost of factory.

The specific embodiment

Embodiment, with reference to accompanying drawing, a kind of grain is except stone desanding jigging machine, comprise main casing support 1, main casing 18 and reductor 8, bearing housing 2 is equipped with in the centre that it is characterized in that main casing support 1, above bearing housing 2, rocker arm assembly 3 is housed actively, and rocker arm assembly 3 right-hand members and drive link 5 are hinged, drive link 5 is hinged with cam 6, and cam 6 is contained in driving cam and connects on dish 7; On rocker arm assembly 3, be equipped with between 4, two cone bucket assemblies 4 of two cone bucket assemblies and be communicated with flexible pipe 30; DN32 reducer pipe 25 is equipped with in cone bucket assembly 4 bottoms in left side, between DN32 reducer pipe 25 and sediment outflow pipe 32, is communicated with discharging hose 24; Cone bucket assembly 4 upper ends are contained on diaphragm of rubber fixed mount 10, and diaphragm of rubber fixed mount 10 is equipped with diaphragm of rubber 11 above, and diaphragm of rubber 11 is equipped with diaphragm of rubber one pressing plate 12 and diaphragm of rubber two pressing plates 13 above; Diaphragm of rubber two pressing plates 13 are equipped with three water-in flange 14 above; T-shaped groove support 15 is housed in the main casing 18 on water-in flange 14, the T-shaped groove 16 of fixed screen deck is housed on T-shaped groove support 15, on the T-shaped groove 16 of fixed screen deck, screen assemblies 17 is housed; At the left end of main casing 18, sediment outflow pipe 32 and drainage conduit 31 are housed; On drainage conduit 31 tops, adjustable weir plate 28 and discharge adjustable plate 29 are housed; Flanged ball valve 23 is housed on sediment outflow pipe 32, and flanged ball valve 23 is equipped with sandstone reservoir component 22 below, and sandstone reservoir component 22 is equipped with DN65 flanged ball valve 21 and sandstone delivery pipe flange 20 below; On the right side of main casing 18, water inlet pipe 33 is housed, water inlet pipe flange 27 and DN32 ball valve 26 are housed on water inlet pipe 33.Reductor 8 is contained on reducer pedestal 9, and reducer pedestal 9 is fixed by bolts on main casing support 1.Main casing 18 is provided with main casing lid 19 above.Reductor 8 is driven by motor.

Grain removes operation principle and the course of work of stone desanding jigging machine: its operation principle is to adopt flow fluctuation principle, in main casing 18, squeezed into the water of pressure by water inlet pipe 33, starter motor pumps with moving cam 6, drive link 5, rocker arm assembly 3 two cone bucket assemblies 4 above by reductor 8, and drive diaphragm of rubber 11 to move up and down simultaneously, make the aqueous medium in main casing 18 form upper and lower fluctuating flow motion.Grain evenly feeds from feeding end, on screen assemblies 17, forms bed.Under fluctuating flow acts on up and down, bed is loose, suspension gradually, and the grain on bed is done each other relative motion and carried out layering according to the proportion of itself.After ascending current finishes, under the effect of descent waterflow, bed is tight gradually, and the sandstone that density is large sinks to bottom, and what grain density was little is distributed in upper strata, realizes the layering of grain and sandstone.While is due to the fluctuating flow that moves up and down and produce of diaphragm of rubber 11, material and sandstone are travelled forward, the material on upper strata pours in drainage conduit 31 by fluctuating flow, enter next procedure, lower floor's sandstone and foreign material fall into sediment outflow pipe 32, enter in sandstone reservoir component 22, reach a certain amount of DN65 of opening flanged ball valve 21 and discharge.

Grain motion state is except outside the Pass having with the density of particle, also there is relation with shape and the granularity of particle, and the impact of granularity and shape is embodied on resistance of medium acceleration, square being directly proportional of its numerical value and relative velocity, therefore in jigging (screen assemblies 17) course of work, the speed of related movement as far as possible reducing between particle and aqueous medium is vital; The motion state (speed and acceleration) of aqueous medium has material impact to the layering of bed in other words to the motion of particle, and therefore only having selection appropriate water speed and acceleration could be to create favorable conditions by density stratification; The identical particle of granularity in delaminating process, highdensity particle will be distributed in lower floor, and low-density particles will be distributed in upper strata; The identical particle of density when layering, the particle of coarsegrain is incited somebody to action substep in lower floor, and the particle of small grain size will be step by step on upper strata.In manipulation, system mainly reaches the object of sorting grain except sandstone by the synthetic operating duty acting in conjunction of the parameter group such as jig frequency, jigging cycle, jigging amplitude, the water yield, hydraulic pressure, discharge velocity and time.In the time of design, to design for different grain.Technical measures in sum, realize production object of the present invention.
