Abstract
The utility model relates to an ultrasonic diver which comprises a pulp pump, a container, an ultrasonic signal measuring device, an ultrasonic signal processing device and a vacuum extractor, wherein an outlet of the pulp pump is connected with the container, the ultrasonic signal measuring device is arranged on the side wall of the container, the ultrasonic signal processing device is electrically connected with the ultrasonic signal measuring device, an extraction opening of the vacuum extractor is connected with a space above the container, and the container is internally provided with a stirring device. The ultrasonic diver utilizes an ultrasonic method for measuring pulp density and overcoming the influence of pulp microbubbles on ultrasonic measurement, thus being suitable for measuring density of various ore pulps and realizing on-line measurement of ultrasonic pulp density.
Description
Technical field
The utility model relates to a kind of device of ultrasonic measurement pulp density, relates in particular to a kind of ultrasound wave diver.
Background technology
For the measurement of pulp density, traditional method is to adopt gamma-ray density meter to measure.Adopt traditional gamma-ray density meter to measure pulp density and have following defective: at first, must survey the density of solids in the ore pulp, the accuracy requirement height should not adopt when the density of solids is unstable in the ore pulp; Secondly, protect when bad, because gamma-rays produces radiation, the personnel that can cause injure and environmental pollution.
Adopting the ultrasound examination pulp density is to measure according to the attenuation principle of ultrasound wave in ore pulp.Ultrasonic probe is placed the outer wall of ore slurry pipeline, and when ore slurry pipeline inner fluid parameter changed, ultrasonic signal changed thereupon.According to the relation between ultrasonic acoustical signal and the pulp density, the utilization computing machine carries out digital processing to the ultrasonic signal that changes, thereby accurately measures pulp density.
There is following shortcoming at least in ultrasonic measurement technology of the prior art:
When containing bubble in the detected slurry, ultrasonic energy is partially absorbed by bubble or absorbs fully, and when causing ultrasound wave to arrive receiving sensor, ultrasonic energy is zero substantially.And in industrial control process, mostly contain bubble in the tested ore pulp, so just can't accurately measure pulp density.
Summary of the invention
The purpose of this utility model is to provide a kind of ultrasound wave diver that can accurately measure pulp density.
The purpose of this utility model is achieved through the following technical solutions:
Ultrasound wave diver of the present utility model comprises ore pulp pump, container, ultrasonic signal measurement mechanism, ultrasonic signal processing device;
Described ore pulp delivery side of pump is connected with container, and described ultrasonic signal measurement mechanism is located on the sidewall of described container, and described ultrasonic signal processing device is electrically connected with described ultrasonic signal measurement mechanism;
Also comprise vacuum extractor, the bleeding point of described vacuum extractor is connected with the upper space of described container.
The technical scheme that provides by above-mentioned the utility model as can be seen, ultrasound wave diver described in the utility model because the ultrasonic signal measurement mechanism is located on the sidewall of container, the upper space of container is connected with vacuum extractor.The bubble that contains in the detected slurry in the container can be extracted, can accurately adopt the ultrasonic measurement pulp density.
Description of drawings
Fig. 1 is the structural representation of the utility model ultrasound wave diver.
Among the figure: 1. ore pulp pump, 2. stirring apparatus, 3. vacuum extractor, 4. ultrasonic signal measurement mechanism, 5. ultrasonic signal processing device, 6. container.
Embodiment
Ultrasound wave diver of the present utility model, its preferable embodiment is:
Comprise ore pulp pump, container, ultrasonic signal measurement mechanism, ultrasonic signal processing device;
Described ore pulp delivery side of pump is connected with container, and described ultrasonic signal measurement mechanism is located on the sidewall of described container, and described ultrasonic signal processing device is electrically connected with described ultrasonic signal measurement mechanism;
Also comprise vacuum extractor, the bleeding point of described vacuum extractor is connected with the upper space of described container.
Can be provided with stirring apparatus in the described container.
Also in conjunction with the accompanying drawings principle of work of the present utility model is described in detail below by embodiment:
As shown in Figure 1, open ore pulp pump (1), ore pulp is inhaled into container (6); Close ore pulp pump (1), open stirring apparatus (2), the ore pulp in stirring apparatus (2) the beginning stirred vessel (6); Open vacuum extractor (3), extract the bubble in the ore pulp, reach and close vacuum extractor (3) after vacuum tightness requires; Stirring apparatus (2) stops to stir, the acoustical signal in ultrasonic signal measurement mechanism (4) the beginning measuring vessel (6), and the acoustical signal that measures is sent to ultrasonic signal processing device (5) handle, measure pulp density.
Adopt stirring apparatus (2) that the effect that the ore pulp in the container (6) stirs is had 2 points: the one, be convenient to vacuum extractor (3) and extract bubble in the ore pulp, the 2nd, prevent that ore pulp from forming precipitation in container (6).The time that vacuum extractor (3) is bled is determined according to concrete operating mode after can handling dynamic test at the scene, is fixed on operation automatically in the program then.Device is controlled by single-chip microcomputer, realizes the normal operation of system's each several part.
The utility model utilizes supercritical ultrasonics technology to measure pulp density, and has overcome in the measuring process ore pulp microbubble to the influence of ultrasonic measurement.Be suitable for the detection of various pulp density, adopt the utility model to detect pulp density, can be good at eliminating the bubble in the ore pulp, realize the online detection of ultrasound wave pulp density.In addition, the utility model does not directly contact tested ore pulp, and is safe and reliable, is convenient to gas defence, explosion-proof, anti-pollution; And have temperature self-compensation function, measuring accuracy is better than 0.2%.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
Claims (2)
