Description

Technical Field

[0001] The present invention relates to the technical field of water-coal slurry detection, and more specifically, to a water-coal slurry fluidity detector. Background Art

[0002] As a clean coal gasification technology, water-coal slurry gasification technology is widely used in the coal chemical industry. Water-coal slurry with coal as the main body has the same liquid fluidity and stability as oil. It not only brings convenience to industrial production, but also promotes the development of the coal industry. With the widespread application of new energy sources such as solar energy, wind energy, tidal energy, hydropower, and nuclear energy, the position of coal in the field of energy generation is gradually replaced. Coal resources are gradually transitioning from the field of energy generation to the field of industrial production. However, as an important performance indicator of long-distance transportation of water-coal slurry, fluidity will become worse and worse with the increase of water-coal slurry concentration. When it reaches a certain concentration, the fluidity of water-coal slurry will undergo a qualitative change, so its fluidity needs to be tested.

[0003] Among them, the patent with publication number CN218239719U discloses a water-coal slurry fluidity detector, including a base, a column, a U-shaped detection tube, a laser pen and a photosensitive receiver. The columns are provided in two groups, and two groups of connecting components, a first mounting beam and a second mounting beam are sequentially provided between the two groups of columns from top to bottom. A glass funnel is detachably connected to one group of the connecting components, and the U-shaped detection tube is detachably connected to the column. The laser pen and the photosensitive receiver are respectively provided in two groups, and the laser pen and the photosensitive receiver are arranged in coordination, and an electronic stopwatch is electrically connected between the two groups of photosensitive receivers.

[0004] When this structure is in use, through the design of U-shaped detection tube, laser pen, photosensitive receiver and electronic stopwatch, the time difference when two groups of photosensitive receivers stop receiving laser is displayed on the electronic stopwatch, and this value is used to show the fluidity of water-coal slurry. However, the flow rate of water-coal slurry under different pressures is different, and the water-coal slurry contains impurities such as solid particles and iron filings, which can easily cause inaccurate detection. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water-coal slurry fluidity detector, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a water-coal slurry fluidity detector comprises a base, on which a flow guide detection component is arranged.

At the same time, as the fluid water-coal slurry in the guide cavity gradually increases, the fluid water-coal slurry can be shunted and transported through each shunt detection tube. The flow meter in the shunt detection tube first detects the flow of the water-coal slurry transported by the shunt detection tube, and the speed of the second impeller during rotation is fixed, so that the pressure when the water-coal slurry is extracted and transported is also fixed, so as to avoid inaccurate detection caused by pressure difference. After the water-coal slurry is transported and tested through the shunt detection tube, it is received and filtered through the filter disc, and then extracted by the first impeller and transported to the gathering hood for gathering. At the same time, the water-coal slurry is detected by the flowmeter in the gathering hood, and the solid particles, iron filings and other impurities contained in the water-coal slurry are filtered out by filtering through the filter disc, so as to avoid inaccurate detection caused by impurities.

The water-coal slurry is properly heated by the temperature-controlled heating rod so that the temperature of the water-coal slurry can be consistent, avoiding measurement errors caused by changes in conditions;
