Problems solved by technology
[0003] 1. Because the ore pulp 19 is basically in a high-speed flow state in the ore pulp process pipeline 1, and the ore powder in the ore pulp 19 is mostly water-insoluble particles, the measurement of the concentration meter sensor 4 is prone to errors caused by the impact of particles, and the particle size Impact will greatly affect the service life of the concentration meter sensor 4;
[0004] 2. Because the high-speed flowing ore slurry 19 will generate a vortex when flowing through the surface of the concentration meter sensor 4, the vortex will also have a certain deviation effect on the measurement of the concentration meter sensor 4;
[0005] 3. The accuracy of the pulp 19 concentration value directly affects the utilization rate of the main process equipment and production raw materials, that is, affects the production efficiency

Embodiment Construction
[0030] The present invention will be further described below in combination with specific embodiments and accompanying drawings.
[0031] Such as Figure 2 to Figure 5 As shown, the main pipe type slurry concentration on-line sampling and measuring device of the present invention is suitable for on-line sampling and measurement of slurry concentration in small-diameter process pipelines. It includes a sampling assembly installed between two sections of process pipelines 1, a sampling tank 5 and a sampling assembly, and becomes an integral part of the process pipeline 1. A sampling inlet 24 is respectively provided on the upper and lower parts of one side of the sampling tank 5. The sample port 24 is connected with the sampling assembly, and a sample outlet 25 is opened on the other side of the sampling tank 5, and the sample outlet 25 is located between the two sample inlets 24, and the sample outlet 25 is connected with the sampling assembly. The top of 5 is provided with a ...

The invention discloses a main-pipe-type on-line pulp-concentration sampling measurement device. The device comprises a sample injection assembly arranged between two process pipes, a sampling tank and a sample discharge assembly, wherein, one side surface of the sampling tank is equipped with two sample injection ports communicated with the sample injection assembly, and the other side surface of the sampling tank is equipped with one sample discharge port communicated with the sample discharge assembly; the sample discharge port is positioned between the two sample injection ports; and the top of the sampling tank is equipped with a concentration meter sensor for detecting the concentration of pulp in the sampling tank. The main-pipe-type on-line pulp-concentration sampling measurement device has the advantages that the structure is simple, and the concentration meter sensor has high measurement accuracy and good stability.
Description
technical field [0001] The invention relates to a sampling and measuring device, in particular to an ore pulp concentration sampling and measuring device for on-line sampling of a small-diameter ore slurry conveying pipeline. Background technique [0002] The measurement of pulp concentration has always been a major difficulty in industrial control in mines, because from the perspective of the production process control link of the mining industry, it is ideal to obtain the concentration of the pulp immediately by online sampling. Obtaining the concentration value of the pulp online can be Immediately carry out real-time control and adjustment on the equipment of the production process to achieve the effect of energy saving and efficiency improvement. Off-line measurement and the concentration value obtained by sampling and measuring in the mine tank have a lag problem for the production process, and the equipment control adjustment is not real-time. For the measurement of ...
