Description
Technical field
The utility model patent relates to technical fields such as mineral processing and sewage disposal, and particularly a kind of, clarification dense to routine, classification, desliming and Separation of Solid and Liquid hopper equipment such as swash plate is dense, clarification, classification, desliming carry out the online weighing sensing arrangement that underflow is regulated and control.
Background technology
Existing Separation of Solid and Liquid hopper formula equipment, enter hopper to slip after, solid grain major part wherein is deposited in the hopper inwall, the deposit that forms is slipped to the underflow valve, discharge from floss hole, and the liquid of clarification is discharged by the overflow launder on hopper top, thereby realize Separation of Solid and Liquid.The primary condition of Separation of Solid and Liquid operation process direct motion mainly is to feed solid material amount and discharge solid material amount maintenance dynamic equilibrium.The untimely regulation and control of underflow discharge capacity in the industrial production, feed solid material amount, if can cause the underflow density instability in continuous fluctuation.If feed the excessive untimely again adjustment underflow discharge capacity of solid material amount amplification, too much when deposit, even can cause underflow to stop up and the interior pernicious heap ore deposit of hopper, thereby and destroyed the dynamic equilibrium of operation can not direct motion, hopper is silted up.
In the practice,, also there is not a kind of detection method to reflect at present because of cause the long-pending constantly situation of variation of solid stockpile in the hopper to the ore deposit fluctuation comprehensively and exactly.Control to underflow density, except that main dependence manual observation experience, also has ray type, ultrasonic type, differential static pressure (barrier film pressure reduction) formula, differential submergence float-type, six kinds of instrument detecting densimeters commonly used such as induction and oscillatory type, underflow density is regulated and control or regulation and controlling of information is provided, existing division is as follows: the ray type densimeter places outside the underflow delivery pipe usually, by ray pass tested ore pulp and be absorbed the back strength retrogression degree measure underflow density, require measured pipeline must be full of ore pulp, and precipitation can not be arranged, layering, bubble etc., otherwise inaccurate.Be that with the weak point of ray type densimeter regulation and control Separation of Solid and Liquid hopper underflow density it can not reflect sedimentary accumulation situation in the hopper comprehensively and truly, can only detect the concentration of underflow pipe partly, and the concentration of underflow pipe discharging some in particular cases with hopper in sedimentary accumulation do not have direct relation, can create a false impression, and ray is harmful.The ultrasonic type densimeter is to make according to the variation principle relevant with pulp density that ultrasonic wave passes the sound intensity before and after the ore pulp, the velocity of sound, acoustic impedance, the method of its detection underflow density and points for attention and ray densimeter are similar, just harmless, price is lower.The differential densimeter of barrier film is to make with the principle that its density and ore pulp post height are directly proportional according to the ore pulp static pressure, be full of on the pipeline of ore pulp, respectively pacify a pressure chamber at a distance of the H distance, the indoor diaphragm of rubber that is equipped with of pressure, clear water and mobile at a slow speed ore pulp are separated, simultaneously the ore pulp static pressure at this place is passed to clear water, the pressure differential and the pulp density of two pressure chambers are directly proportional, and this pressure differential available head transmitter is measured.This densimeter is simple in structure, and cost is low, but volume is big, and precision is low.In addition because ore pulp can layering in the Separation of Solid and Liquid hopper, and sediment is deposited in headwall, the concentration of ore pulp layer each point that is exactly same horizontal plane is all inequality, and therefore, the differential densimeter of barrier film can not react sedimentary accumulation situation in the hopper comprehensively and truly.Differential submergence float-type densimeter is made according to Archimedes principle, two floats that volume differs in size of suspention on two arms of balance, be immersed in the ore pulp, when a certain normal concentration, make the balance balance through counterweight, when pulp density changed, two suffered different buoyancy of float made the unbalance inclination of balance, change in concentration is big more, and gradient is big more.Change the inclination size into the signal of telecommunication with sensors such as differential converters, the variation of indication pulp density.The precision of this densimeter is not high, and is subject to multiple factor ten and disturbs.Because of ore pulp layering in the Separation of Solid and Liquid hopper, sediment is deposited in the hopper inwall disorderly and with constantly variation of underflow discharging, situation is very complicated, and the float-type densimeter can only reflect very limited localized variation, and deposit collapses and waits and can produce serious interference to it.Induction densimeter is mainly used in the density that detects magnetic heavy suspension.Instrument is made up of measuring tube, electromagnetic induction coil and conversion display part.When magnetic material content in the tested suspension changes, cause that induced-current changes in the induction coil, and then can converse the variation of suspension concentration that induction densimeter can only detect the density of magnetic thing heavy suspension, and is invalid to conventional ore pulp.When the oscillatory type densimeter was crossed the measuring tube that is vibrating according to flow of slurry, the horizontal free running frequency of pipe changed the principle that changes with pulp density and makes.Though its sensitivity is very high, measuring tube is subjected to the ore pulp serious wear, and the instrument price is more expensive, is used for coal industry more, and the oscillatory type densimeter also can only detect localized variation in the hopper.
In sum, the method that is used for Separation of Solid and Liquid hopper underflow regulation and control at present all can not be reacted the quantitative change situation of hopper content comprehensively and truly.
