The online density monitoring device solves the problem of the prior online density monitoring device that the structure is complex and radiation hazard exists. The novel online density monitoring device comprises a digital type electronic weighing device, a spiral vessel bent from pipe material and fixed on the digital type electronic weighing device; wherein, a liquid inlet pipe is arranged at a liquid inlet opening of the spiral vessel, a fresh water pipe mutually connected with a tap water pipe and a washing liquid pipe mutually connected with a material feeding pipeline of the washing liquid are fixed on the liquid inlet pipe through a three-way pipe, a liquid returning pipe mutually connected with a washing liquid returning pipeline is arranged at a liquid outlet opening of the spiral vessel, and gate valves are respectively arranged on the fresh water pipe and the washing liquid pipe. The online density monitoring device has the advantages that the structure is simple, the operation is convenient, and the density of the washing liquid can be obtained in real time; therefore, the purpose of online monitoring is realized.

Description

Novel density on-Line Monitor Device

Technical field

The utility model relates to a kind of density on-Line Monitor Device that monitor the situation of change of washing process washing liquid density the coal washery that is used for, and specifically is a kind of simple in structure, novel density on-Line Monitor Device that degree of accuracy is high.

Background technology

When the situation of change of coal washery washing liquid density in to washing process is monitored, subset detects and two kinds of approach of manual inspection, wherein, the manual inspection program is loaded down with trivial details, the cycle is long, waste time and energy, and can not reflect the density of real-time washing liquid continuously, what directly influence was produced carries out smoothly, also influence simultaneously the quality of washing product, greatly reduced the washing operating efficiency; Gamma-rays density on-line monitoring system is generally adopted in Equipment Inspection, this system has the advantage that monitoring is directly perceived efficiently, can realize automatic control, but its complex structure, the long-term use, there is the radioelement radiation injury in operating personnel, and can causes certain pollution to environment.

Summary of the invention

The utility model provides a kind of novel density on-Line Monitor Device in order to solve the problem that has the denseness on-line detection device complex structure now, has radiation risk.

The utility model is to adopt following technical scheme to realize: novel density on-Line Monitor Device, comprise the digital electronic scale, be fixed in weigh the spiral fashion container that is bent into by tubing on the face of digital electronic scale, the inlet of spiral fashion container is provided with feed tube, feed tube is fixed with the clear water pipe that links to each other with running water pipe, the washing liquid pipe that is connected with washing liquid material loading pipeline through threeway, the liquid outlet of spiral fashion container is provided with the liquid back pipe that links to each other with washing liquid return pipeline, and clear water pipe and washing liquid pipe are respectively equipped with gate valve.

Before the use, open the gate valve on the clear water pipe earlier, fill with clear water in the spiral fashion container on the digital electronic scale, according to V _Container=M _Water/ ρ _Water, draw spiral fashion volume of a container V _Container, close the washing liquid (or claiming dielectric fluid) that clear water pipe closer valve injects known density ρ then, according to ρ _Liquid=M _Liquid/ V _Container, meter constant K=ρ/ρ _Liquid, meter constant K is subjected to the flow of dielectric fluid, the influence of various factors such as concentration of dielectric fluid, should carry out repeated detection to calculate mean value-meter constant K;

During use, concrete operation method is as follows:

1, with the switch opens of digital electronic scale, with meter constant K and V _VolumeRatio-K/V _VolumeIn the unit price of input digit formula electronic scales;

2, before washing liquid material loading, the dielectric fluid pipe closer valve and the clear water pipe closer valve of monitoring device are closed, after treating that washing liquid material loading is normal, open washing liquid pipe closer valve, the numerical value that shows from digital electronic scale price display screen (is ρ=M for the density value ρ of washing this moment liquid _Liquid* K/V _Volume);

3, stop washing liquid material loading after, washing liquid pipe closer valve cuts out, open clear water pipe closer valve, washing liquid in the spiral fashion container is rinsed well, so that next washing liquid material loading is unaffected when detecting.

The utility model is simple in structure, and is easy to operate, can obtain washing liquid density in real time, realizes the purpose of on-line monitoring, has following beneficial effect:

1, aspect operation detection, compare the time that has shortened Density Detection greatly with manual inspection, and can detect at any time, compare simple to operate with gamma-rays density on-line monitoring system; It does not have abstruse theory to do basis, and common employee just can operate, regulate check and correction, maintenance; And with the manual inspection not super 0.01g/cm3 of ratio error mutually;

2, aspect value, its volume is little, takes up an area of fewly, and in light weight, materials used is simple, and cost is low, and manufacturing cost needs more than 500 yuan and original more than 20 ten thousand yuan equipment to compare approximately, economizes on the use of funds about 200,000 yuan;

3,, got rid of of the harm of existing equipment harm ray, for worker's physical and mental health provides sound assurance to operator and post personnel's health at secure context;

4, aspect social benefit, denseness on-line detection device described in the utility model replaces gamma-rays density on-line monitoring system, has got rid of a major hazard source, has eliminated the pollution of ray to air, soil and water resource, has improved the environment of coal washery greatly.
