Description

Rotary drum type vortex pump, take silt device, silt dredger and dredging method
Technical field
The present invention relates to silt Dredging Field, particularly for performing the vortex pump of dredging function, taking Silt device, silt dredger and dredging method.
Background technology
Fluid dynamic machinery equipment in terms of suction and conveying mud (husky) under water, conveying, hydraulic reclamation is explored by people For many years, dominant form is: with Pulp pump (dredge pump) as fluid dynamic machinery, mechanical energy is turned Becoming potential energy and the dynamic pressure energy of fluid liquid (silt), suction inlet installs reamer head and rake head, reaches To suction and conveying mud (husky) purpose.
And the operation principle of Pulp pump (dredge pump), it is the semi-open type with high speed rotating and unshrouded impeller, The blade profile of blade produces radial centrifugal force effect and the acting of axial force convection cell, and fluid produces acceleration, And with static spiral case generation fricting movement, convert mechanical energy into potential energy and dynamic pressure energy, spiral case will stream Body is uniformly discharged or proceeds to next stage leaf.Range of flow 100-20000m3/ h, lift is about 10-200m, Its dynamic trait belongs to low-lift pump scope.
Prior art also exists Railway Project:
1) dynamic trait of Pulp pump (dredge pump) determines underflow (volume) ratio and must not exceed 30%, After 30%, the efficiency curve dramatic decrease of its pump, working range below 20% preferably, actual Situation is about 10%, in case mud conveying pipeline and pump housing blocking.
2) impeller at static spiral case and high speed rotating defines flow channel space, the merit of fluid consuming Rate brings the biggest friction loss while obtaining potential energy and dynamic pressure energy by runner friction, and at leaf Wheel back produces back-pressure district, causes hydraulic loss very big, and effective shaft power reduces.The leakage of the pump housing is also Power attenuation can be produced.Institute is lossy accounts for shaft power 30%.
3) stall and surge phenomenon, when the angle of attack increases, the afterbody flowing of blade back side produces and separates, External force increased and the increase of resistance (mainly form drag) is bigger, and blade lifting resistance ratio reduces, After the angle of attack increases to a certain marginal value, flow separation point moves forward, and Disengagement zone expands, and causes lift obvious Decline and resistance sharply increases, produce stall, surge.When rotating stall is against the angle of impeller direction of rotation Speed (about 30% 80%), alternation stall power frequency is equal or close to Natural Frequency of Blade, In addition to affecting the change of fluid pressure, generation is resonated even leaf destruction by blade, output flow Critical flow must be much larger than, but in reality, the density of fluid-mixing, fluid produces in inlet Raw elastic wave frequency, amplitude is all change.When rate of flow of fluid is in turbulent region, real fluid flows Mostly mode in pipeline suction chamber and discharge line, is big and small eddying motion, and the angle of attack is also one The functional relationship of individual change, Changing Pattern is difficult to grasp.
4) due to cavitation, the setting height(from bottom) of pump should meet < HS=HSMAX0.3 >, actual Setting height(from bottom) meetsHs be producer (1325Pa and The clear underwater experiment of 20 DEG C flows out.When taking silt under water, limit water surface height installed above, exceed During numerical value, relay vacuum pump need to be installed under water additional, add frock difficulty, the fluid back of the body of pump intake Pressure is restricted, and mud (husky) inhaled concentration of fluid is also restrained, system optimum condition departing from Efficiency of pump optimum condition.
5) in order to abolish mud (husky) layer concrete under water, improve the dense oar ratio of mud (husky), mostly use The rotation reamer head that configuration power drives, reamer head is arranged on reamer frame, with certain length suction tube Weld together, hinged with hull sliding bearing, sagging with water-bed shape by this section of rigid body self gravitation The suction mud work surface formed an angle.In actual motion, reamer rotates and need to overcome self gravitation, with under water Counteracting force at the bottom of mud, the pressure of the depth of water, water-bed underflow and turbulent flow whirlpool vectorial force, guarantee Work surface works, and need to consume reactance capacity very big.The mechanical energy of reamer, the dynamic pressure energy of Pump Suction Nozzle, make Fluid (mud, husky) produces the vortex vectorial force of Way in, and this power need to overcome fluid mass inertia force, Buoyancy own, the lowest (about 15%) that forms concentration is even lower, and underflow is bigger than amplitude of variation. Production efficiency is low.
6) when operating mode is gluing soil layer concrete, its shear viscosity intensity is 150n/cm2, cutting of reamer Cutting radius big, the required shaft power order of magnitude is the biggest, and water is the deepest, and Underwater Pressure is the biggest, and counteracting force is more Greatly, power consumption is the biggest, and does not has dependency relation with underflow specific efficiency, and required platform cost is the most very Height, the cost performance of whole production system is the lowest, and rate of return on investment is the lowest.
7) use dragging rake head in navigation to break layer concrete, inhale mud (husky), this side by mud pump lift Formula is lower than aforesaid way efficiency, and the muddy pollution in waters is bigger.
8) screw pump is used for inhaling mud hydraulic reclamation aspect does not also have large-area applications, and its main cause is 1. spirals Blade and the gap of barrel shell cause the continuous disc friction losses of fluid excessive, cause efficiency far to be less than centrifugal Water pump.2. excessive due to the back-pressure district, back of helical blade, current are lost in superposition between each pitch Producing, spiral pump lift is inversely proportional to the relation of power and flow, causes lift little, and flow is relative Greatly, power loss is huge.
