Abstract

The utility model provides a densimeter capable of continuously measuring flowing slurry in a pipeline, and aims to overcome the technical defects of the existing slurry densimeter for slurry discharge pipelines. The utility model adopts the technical scheme as follows: the weight and the volume of flowing slurry are measured by using the weighing method, and then through processing data by a computer, the slurry density value is displayed in real time. The densimeter disclosed by the utility model has the characteristics as follows: 1, a floating body is independently placed in the slurry and is not connected slurry input/discharge pipelines, so as to ensure the accuracy of density measurement; 2, the additional stress applied to the floating body by a flowing liquid can be controlled within an effective accuracy range of measurement of the densimeter; and 3, through the slurry density value acquired and computed by the computer, the density variable value of the slurry flowing in the pipeline can be reflected instantly and the effective accuracy of the measurement can be ensured. Compared with the existing pipeline slurry densimeter, the densimeter disclosed by the utility model has the advantages of simple structure, simplicity in operation and low cost, and is a pollution-free environmental-friendly densimeter.

Description

The Density Measuring Instrument of mobile mud in a kind of METHOD FOR CONTINUOUS DETERMINATION pipeline

Technical field:

The utility model relates to a kind of instrument of measuring mud density, is used for the mud density that flows in the METHOD FOR CONTINUOUS DETERMINATION pipeline.

Background technology:

In the dredging industry, what mud density mensuration was with the most use in the existing dredge pipe line is the gamma-rays Density Measuring Instrument.

The gamma-rays Density Measuring Instrument is to adopt gamma-rays to measure, and in this instrument use procedure strict environmental requirement is arranged, and careless slightly meeting is to the surrounding enviroment harmful.

The utility model provides a kind of new-type mortar Density Measuring Instrument, the mud density that it flows in can the METHOD FOR CONTINUOUS DETERMINATION pipeline, Density Measuring Instrument is to adopt weighing method to measure weight and the volume of mobile mud, then carries out data by computing machine and processes the also real-time mud density numerical value that shows.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of Flows slurry density test instrument, overcomes the technological deficiency that spoil disposal pipeline mud density instrument exists in the existing dredging industry.

For solving above-mentioned technological deficiency, the technical solution of the utility model is to adopt Archimedes principle, measures continuously weight and the volume of the mud that flows with weighing method, then carries out data by computing machine and processes the also real-time mud density numerical value that shows.

The utility model feature is: slurry density test instrument mainly contains four parts such as sludge barrel, buoyancy aid, LOAD CELLS, computing machine and forms.

Configuration mud input pipe, mud vent pipe, filter plate, liquid level display, isocon and pipe control valve etc. on the sludge barrel.

The extra-stress that the sectional area ratio of mud input, vent pipe and sludge barrel should satisfy the flowing liquid generation can be controlled in the effective accuracy scope of Density Measuring Instrument measurement.

Buoyancy aid is tubular body, and cone is made at the top, and the weight of buoyancy aid should be greater than the survey weight that arranges buoyancy aid volume mud, and the materials such as buoyancy aid useable glass or stainless steel are made.

LOAD CELLS should adopt range less, precision be per mille above draw, pressure transducer.

The corresponding interface of allocation of computer and sensor and software for calculation.

Densitometer when work, in pure water, the buoyancy aid volume is carried out calibration first, the weight of buoyancy aid in the METHOD FOR CONTINUOUS DETERMINATION mud then, sensor gathers weighing data and sends computing machine to and calculate, store and show in real time by special software.

The utility model characteristics are:

1, buoyancy aid independently is positioned in the mud, with mud input, vent pipe without being connected, guarantee the precision of measuring density of slurry.

2, the mud that flows into sludge barrel can evenly pass through around the buoyancy aid mud by filter plate, and the mud density unevenness produces when preventing from measuring.

3, buoyancy aid vertically places certain depth mud, and the extra-stress that flowing liquid produces can be controlled in the effective accuracy scope of Density Measuring Instrument measurement.

4, the mud density value by computer acquisition, calculating, the mud density changing value that flows in can instantaneous reflection pipeline, and guarantee the effective accuracy measured.

Compare with existing pipeline mud density instrument, the utility model Density Measuring Instrument has structure, simple to operate, and cost is low, is a kind of Density Measuring Instrument of pollution-free environment-friendly type.

Description of drawings

What accompanying drawing represented is the structural representation of the utility model Density Measuring Instrument.

Embodiment

The utility model Density Measuring Instrument mainly contains several parts such as mud input pipe 1, filter plate 2, sludge barrel 3, buoyancy aid 4, LOAD CELLS 5, computing machine 6, mud vent pipe 7, liquid level display 8, isocon 9, pipe control valve 10 and forms.

Embodiment is: the mud in the dredge pipe line flows into Density Measuring Instrument mud input pipe 1, and the filter plate 2 by the sludge barrel top flows into sludge barrel 3 again.

Mud is the buoyancy aid 4 by linking to each other with LOAD CELLS evenly, and the buoyancy that buoyancy aid 4 arranges the liquid volume generation changes and changes along with mud density.

LOAD CELLS 5 is directly inputted weighing and is calculated instantaneous mud density value in the computing machine 6.

The volume of buoyancy aid 4 should be before measuring density of slurry calibration in advance, can in pure water, carry out calibration.

Mud vent pipe 7 is positioned at the sludge barrel below, makes the mud turnover have continuity.

Liquid level display 8 is positioned at the sludge barrel outside, is communicated with the sludge barrel bottom, shows liquid level in the sludge barrel.

Isocon 9 exits are positioned at mud input pipe 1 top, are communicated with the sludge barrel top, prevent that liquid level exceeds nozzle in the sludge barrel.

Pipe control valve 10 is regulated and is imported and exported liquid level in flow and the cylinder.
