Abstract
Description
Technical Field
[0001] The utility model relates to a bypass diameter measuring type particle size analyzer device, in particular to an instrument for online measuring the particle size of rocks in ore pulp. Background Art
[0002] There are two main methods for real-time detection of slurry particle size in mineral processing, namely, caliper-type mechanical particle size analyzer and ultrasonic particle size analyzer. There are basically two ways to detect caliper-type mechanical particle size analyzer. One way is to directly install it on the pipeline to measure the slurry in the pipeline. This method is simple to install and inexpensive, but it has certain disadvantages: for example, the fast flow rate of slurry in the pipeline causes greater impact vibration and wear on the probe; if the diameter of the pipeline is large, the transmission rod of the probe must be made very long, which affects the measurement accuracy; it is always in the slurry and cannot self-clean and self-calibrate the zero point. The other method is similar to the ultrasonic particle size analyzer, which is designed into multiple flow channels to introduce the slurry into the instrument and return it to the corresponding process point after measurement. This method can measure multiple process points, but the sampling pipeline is long and easy to clog. During installation, the platform height and position need to be determined according to the drop of each pipeline, and the flowability of drainage and return needs to be considered. The construction volume is large and the maintenance is cumbersome. Summary of the invention
[0003] The utility model aims to provide a diameter measuring particle size analyzer device which is easy to install, automatically calibrates zero, is not easy to be blocked and has good shock resistance.
[0004] A bypass caliper particle size analyzer is a single-channel caliper particle size analyzer. It consists of a sampling unit, an automatic flushing unit, a particle size detection unit, a sample return unit and a control unit. It is characterized by a small slurry drop, not easy to block the mine, and does not require a special installation platform or base. It mainly solves the functions of automatic flushing and automatic zeroing. It is an online slurry particle size analyzer with a simple structure, good seismic resistance, small temperature drift and low cost.

[0006] According to the above scheme, the sampling pipe section is installed in the ore-incoming direction of the slurry pipeline, and the ore-returning pipe section is installed in the ore-discharging direction of the slurry pipeline.
[0007] The beneficial effects of the utility model are: small slurry drop, not easy to block the mine, reducing the labor intensity of workers; no special installation platform or base is required, the structure is simple and the cost is low; it has the functions of automatic flushing and automatic calibration, high precision, and can perform online real-time measurement.

[0012] The functions of each part of the utility model are specifically described in conjunction with Figure 2:
[0013] The sampling unit (15) is responsible for taking out a representative slurry sample from the slurry process pipeline, passing through the automatic flushing unit (16) and entering the particle size detection unit (17) for sample analysis. The sample return unit (19) returns the slurry sample to the original process pipeline. The control unit (18) is responsible for fitting the particle size distribution, calculating the particle size interval value to be measured, controlling the automatic flushing unit (16) to clean the pipeline and the probe, and providing a working environment for automatic zero point calibration for the particle size detection unit (17).
[0014] The working principle of the utility model is specifically described in conjunction with Figure 1:
[0015] A bypass diameter measuring particle size analyzer device, characterized in that it comprises a sampling pipe section (2) and a sampler (3) installed on the sampling pipe section (2), wherein the lower part of the sampler (3) is connected in sequence to a manual hose valve (4), an upper flushing flange (5), a pneumatic hose valve (7), and a lower flushing flange (8), and then to a particle size detection probe (9), wherein the outlet of the particle size detection probe (9) is connected to a return pipe section (12) via a rubber hose (11), and a control unit (10) transmits data with the particle size detection probe (9) via a cable (14), and the control unit (10) can also control the opening and closing of the upper flushing flange (5), the lower flushing flange (8), and the pneumatic hose valve (7). The upper flushing flange (5) and the lower flushing flange (8) are made of ultra-high molecular weight polyethylene.
[0016] During particle size measurement, the control unit (10) issues a command to set both the manual hose valve (4) and the pneumatic hose valve (7) to an open state, and the slurry flows from the pipeline (1) into the sampling pipe section (2), wherein a portion of the slurry is taken out by the sampler (3), flows into the particle size detection probe (9) for measurement, and then flows into the pipeline (13) through the return pipe section (12).
[0017] When the particle size analyzer is automatically calibrated, the control unit (10) closes the pneumatic hose valve (7) to cut off the passage of the slurry sample. At the same time, the control unit (10) opens the upper flushing flange (5) and the lower flushing flange (8). Flushing water is returned to the sampler (3) through the water pipe (6) via the upper flushing flange (5) to prevent the slurry from settling and blocking the sampling channel. Flushing water is flushed through the lower flushing flange (8) to the particle size detection probe (9). After ensuring that the probe is flushed clean, the lower flushing flange (8) is closed and the particle size analyzer is automatically calibrated.
[0018] When the particle size analyzer needs to be repaired, the manual hose valve (4) can be manually closed to carry out maintenance work on the downstream parts.
