Description
Technical field
The invention belongs to mud, waste oil and wastewater treatment and the chemical field of metallurgy industry emulsion of rolling mill system, particularly a kind of method for designing that liquid level of emulsion sludge is detected control.
Background technology
Emulsion sludge be the Magnetic filtration device machine equipment discharge contain impurity mud such as iron powder because ferrous powder granules is little and wherein mixing emulsion greasy filth, the viscosity of mud is big, mobile poor, makes that the detection of liquid level is relatively more difficult in the sludge tank.
Mainly adopt tubular type liquid level gauge, float type level gauge, remote level indicator (ultrasound wave, radar level gauge etc.) to detect in the past, but existed the problem of the following aspects:
1, tubular type liquid level gauge
Because institute's medium of surveying can stop up the cross over pipe of tubular type liquid level gauge, perhaps the media attachment of surveying manage in estimating, causing can't normal observation.
2, float type level gauge
For the different mud class medium of proportion, the buoyancy that float produces has nothing in common with each other, and therefore can't make the float type level gauge that is fit to various media.
3, remote level indicator
As ultrasound wave, radar level gauge etc., owing to be subject to the influence of dielectric viscosity, so metering is not accurate enough, and the price height, the Maintenance and Repair trouble.
Summary of the invention
The purpose of this invention is to provide a kind of detection control design method for liquid level of emulsion sludge, it has solved above-mentioned existing in prior technology problem, on the basis of float type level gauge, improve, change into adjustablely with the weight of float in the past is non-adjustable, and then design a kind of new adjustable Level Detection control method.
Technical solution of the present invention is as follows:
A kind of detection control design method for liquid level of emulsion sludge may further comprise the steps:
A, in casing or tank body the splendid attire fluid to be measured;
B, the liquid level floating drum is hung in casing or tank body by the leading block group by rope, the other end of rope is outside the leading block group is suspended from casing or tank body and connect slide block and pointer;
C, slide block and pointer move up and down in the slide block guide groove, and when slide block weight during greater than floating drum weight, floating drum rises, and slide block descends;
D, by progressively injecting liquid, in the whole stressing conditions of balance liquid level, up to the liquid level gauge operate as normal to the floating drum liquid injection port;
E, adjust finish after with the liquid injection port sealing, in case liquid evaporation and destruction of balance in the floating drum.
After the described step C, before the step D, several are set near switch, with the liquid level and the participation control automatically of liquid medium in the remote observation jar in the slide block side.
Described several are arranged on the slide block guide groove side of slide block side near switch.
The design main points of detection control design method for liquid level of emulsion sludge of the present invention are, the weight of the float that will contact with medium changes into adjustablely by non-adjustable in the past, and the form that is about to float changes open-core type floating drum or hollow float into.For the medium of different viscosities and proportion, by its actual buoyancy size, can in hollow pontoon, add liquid and adjust floating drum weight, make the liquid level gauge floating drum reach weight balancing, to guarantee the operate as normal of floating drum.
Major advantage of the present invention is as follows:
1, be used for the measurement and the control of different liquid medium liquid levels, applied widely.
2, the measuring accuracy height is intuitive and reliable.
3, simple in structure, cost is low.
4, easy to operate, safeguard simple.
The present invention has overcome the shortcoming of using under the operating mode that existing various liquid level gauges are big in liquid viscosity, flowability is poor, solved level gauging and control problem that conventional liquid level gauge can't be used for this type of mud, the stable operation that guarantees emulsion system key equipment Magnetic filtration device machine has been played a key effect.
Simple in structure by the detection control apparatus that the inventive method is implemented, low cost of manufacture, maintenance is easily.
