Description

Double helix water and sand separating device

Technical field

The present invention is a kind of double helix hydraulic set of formula of being association of activity and inertia.

Technical background

The characteristics of numerous rivers in China North China, northwest loess and the band of Xinjiang one all have muddy water high, silt content is high, mud Husky homogeneous, particle is superfine, and the husky separate difficulty of water is very big.The sediment concentration of river up to it is tens of, even hundreds of kilograms often stand Square rice, and sediment grain size is superfine, and the silt of generally less than 0.03mm particle diameters accounts for containing husky total amount more than 40%, deals with ten Divide difficulty, huge energy consumption and burden is caused to feedwater is irrigated.And instantly, the more universal point husky device of China is all only sharp A point sand is realized with the principle settled by self gravitation in Sha Shui, point husky present situation that efficiency is slow, separation degree is low is caused, and The mode that the present apparatus is then combined using the dynamic condition and statical condition of water, realizes and expeditiously divides sand.

The content of the invention

By analyzing the two-phase fluid in water sand fluid-mixing（That is continuous phase-water, dispersed phase-sand）Characteristic, combined branch It is double that the basic mechanical knowledge such as stress characteristic, current continuity equation in family name's power theory, Sha Shui have devised a kind of sound formula Spiral water and sand separating device.

The present invention realizes that the technical scheme of goal of the invention is：Double helix water and sand separating device, it is characterized in that：Current are divided into stream Speed and all equal two strands of flow, enter the dynamic moisture sand portion of device from front tangential water inlet and rear tangential water inlet respectively Divide A, stronger eddy-currents is formed wherein, the flow velocity of current can reach the coriolis force of eddy-currents generation more than centrifugal force, point Dephasing-sand abandons husky mouth discharge to center convergence containing the husky water first order from below of abandoning, regulation hand sluice valve allow to and When sand discharge simultaneously control above first order clear water output flow（Because the silt content of water, i.e., it is basic one containing husky concentration Fixed, the valve apertures size that hand sluice valve control is fixed at some, it becomes possible to exclude silt in time, it is ensured that silt will not heap Product）, first order clear water enters into the hydrostatic point sand part B of device from top, and in hydrostatic point sand part, B leading portions are provided with buffering Area, sets buffer set timing gate valve below buffering area, and time opening buffering area timing gate valve removes sand；In hydrostatic point sand Part B, the current for being mingled with sand slowly rise around spiral stairway plate, and back taper and installation two are set in hydrostatic point husky part B bottoms Level abandons husky mouth timing gate valve, and two grades of time opening abandons husky mouth timing gate valve and removes sand, and clear water is along spiral stairway plate lower surface Slowly move up, overflowed from second level clear water output, and sand then abandons husky mouth discharge from the second level.

Buffering area timing gate valve and two grades abandon the gate valve that husky mouth timing gate valve is all improved to automatically control.Because water contains Sand amount is certain, according to the operation at initial stage, the relation of silting and time can be obtained, between obtaining a rational sand discharge It is also feasible every the time.The principle that the gate valve for automatically controlling is realized：A pair of diodes is set in water, and one is light-emitting diodes Pipe, one is photodiode, and the illumination that photodiode is collected dies down to certain degree（What the gate valve for setting was opened Threshold value）Control gate valve is opened.Light shutter device is a kind of technology commonly used in automatically controlling, and is that by.

The function that this patent can be played is：The present apparatus can form powerful by the husky part of dynamic moisture using two strands of tangential current Eddy-currents, and ingenious combination coriolis force is theoretical, completes efficient waterpower point sand, and not against outside energy.Hydrostatic desilting portion Divide and cause to be adsorbed onto on staircase boards in the very short vertical ranges of Sha Neng using spiral stairway structure, and Sha Congding is significantly greatly increased Portion has time enough to complete sedimentation to the move distance at top.Two grades when abandoning husky mouth timing gate valve and opening, the water energy on top is reached Most by the silt deposited on spiral stairway plate impacts two grades and abandons husky mouth timing gate valve, is then discharged out.Two parts knot Close with the separation that the water sand in muddy water can be carried out higher degree, fast speed, and not against outside energy, appoint without addition What chemistry agent.The device can be applied to the husky separation of water of big particle diameter, small particle, can well meet field irrigation water intaking The need for.

Specific embodiment

Speed silt carrying flow higher is divided into flow velocity and flow is equal（Difference in height is equal with caliber equal to be realized）Two Stock does not enter the dynamic moisture sand part A of device from front tangential water inlet 1 and rear tangential water inlet 2, formed wherein compared with Strong eddy-currents 10.When the coriolis force that eddy-currents is produced is more than centrifugal force（Realized by improving water velocity, that is, improved into water Mouthful height realize）, dispersed phase-sand can to center convergence, and then containing it is husky abandon water and can abandon husky mouth 3 from the first order discharge.And Water-carrying capacity is abandoned when inlet flow rate is more than（The first order abandons the flow that the sand discharge of husky mouth 3 is taken away）When, have unnecessary limpider One-level clear water overflows from first order clear water output 4, and enters into the hydrostatic point sand part B of device.And can manually lock Valve 5 adjusts out the flow of clear water（Hand sluice valve）.The husky part part B leading portion of hydrostatic point is provided with buffering area 6, makes the traveling of water Flow velocity diminishes, and sets the sand that Miniature timing automatic water valve excludes buffering area precipitation in lower section.In hydrostatic point sand part B, Current and sand slowly rise around spiral stairway plate 8.Spiral stairway plate can reduce the distance of husky sedimentation and lengthen husky traveling away from From so that sand is easier to be deposited in swash plate（The gangboard of spiral）On.Surrounded and watched in buffering area and be provided with buffering area timing gate valve 12, timing Exclude the sand of buffering area alluvial.The appropriate sand covered on spiral plate can change the hydraulics of spiral plate, further such that husky Easily settle.Set back taper and install two grades in hydrostatic point husky part B devices bottom and abandon husky mouth timing gate valve 11, time opening valve Door removes sand, realizes zero artificial real time execution.Clear water is slowly moved up along spiral stairway plate lower surface, finally from second Level clear water output 9 overflows, and sand is then abandoned husky mouth 7 and discharged finally from the second level, and abandoning husky mouth timing gate valve 11 by two grades controls Sand discharge.Whole process enables to the separation of water sand very high degree, and by model test, the device divides husky rate up to more than 95%, The application of Automatic slucie valve can realize that twenty four hours zero artificially divides sand, disclosure satisfy that the requirement of agricultural irrigation, domestic water.
