Novel online concentration meter

Technical Field

The utility model relates to the field of meters, in particular to a novel online concentration meter.

Background

The concentration meter is an industrial solid-liquid mixed concentration measuring instrument, the concentration is an important technical parameter in the mineral separation field, and the accuracy of the concentration is important data of the sorting index.

Preferably, the outer side of the lower end of the row thick pipes is integrally formed with an outer side bulge.

(III) beneficial effects

Compared with the prior art, the utility model provides a novel online concentration meter, which has the following beneficial effects:

1. the novel online concentration meter utilizes the density difference of solid-liquid two-phase objects to detect the pressure of a mixture under a certain liquid level, the higher the density content is, the larger the pressure is, the concentration can be detected, and the detected concentration of the solid-liquid mixture is detected by a pressure sensor. The solid-liquid mixture continuously enters the main detection pipe from the slurry inlet pipe through the rubber pipe valve to flow upwards. Due to the slower flow rate, a portion of the settled solids is discharged through the lower discharge coarse pipe. The ore pulp flows upwards from the detection pipe to the overflow port to contact the detection electrode, and a clear water pipe on the other side of the lower end of the detection pipe continuously feeds a small amount of clear water, so that a pressure sensor on one side of the clear water pipe is ensured not to contact the ore pulp. The pressure sensor starts to detect pressure after the detection electrode contacts the ore pulp, and the concentration is obtained by converting the numerical value of the pressure sensor and the concentration by establishing a relation. The purpose of accurately measuring the concentration can be achieved after the concentration is calibrated.

2. The novel online concentration meter detects concentration online in real time, skillfully isolates the pressure sensor by using clear water, and can avoid the pressure sensor from directly contacting flowing ore pulp, so that the sensor is worn.
