Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.
Example 1
The attached drawing is a specific embodiment of the invention, as shown in fig. 1.
The flow stabilizer of the concentration measuring instrument in the embodiment mainly comprises a flow stabilizing pipe 1, a flow stabilizing valve 2, a flowmeter 3, a reducer pipe joint 4 and a main pipe 5. The inner diameter of the flow stabilizing pipe 1 is the same as that of the field ore pulp conveying main pipeline, and the flow stabilizing pipe can be welded or connected by using a tee joint and the like. The flow stabilizing pipeline is provided with an electric flow stabilizing valve 2, and the flow stabilizing valve 2 is controlled in real time by measuring the flow of the ore pulp flowing through the concentration meter by adopting an electric gate valve, so that the flow of the ore pulp flowing through the concentration meter is stabilized. The main pipe 5 is connected with the flowmeter 3 through a reducer pipe joint, and a concentration meter (a differential pressure type pulp concentration meter is shown in the figure, but the invention is not limited to the differential pressure type pulp concentration meter) is installed at the rear end of the flowmeter 3. The small-caliber side of the reducer pipe joint 4 is DN125, the inner diameters of the large-caliber sides of the main pipelines are the same, and the length of the large-caliber sides is 600 mm. The front end of the concentration meter is provided with a flowmeter 3, an electromagnetic flowmeter is adopted, the caliber is DN125, and the flow of ore pulp flowing through the concentration meter is measured in real time through the flowmeter 3. Through controller connection control between electromagnetic type flowmeter and the electronic flow stabilizing valve, the flow signal real-time transmission that flowmeter 3 surveyed to the controller, the degree of opening and shutting of electronic flow stabilizing valve is controlled to the controller, realizes flow control, keeps the flow that flows to the concentration meter to be unlikely to too high to alleviate the concentration meter wearing and tearing that the concentration meter caused because of the flow is too big.
In the operation process, the flow meter 3 can measure the flow of the ore pulp flowing through the concentration meter in real time, and the flow of the ore pulp flowing through the concentration meter is changed by adjusting the opening of the flow stabilizing valve of the flow stabilizing pipeline. When the flow passing through the concentration meter is larger, the valve opening is properly opened, and vice versa. So that the flow rate flowing through the concentration meter is stabilized within a set range (e.g., 100-130 m for cultivation/h). It is thus clear that the utility model discloses a current stabilizer can effectively prolong the life of pipeline type concentration meter, and the ore pulp flow of the concentration meter of steadily flowing through effectively reduces dynamic pressure and disturbs the influence to concentration measurement, reduces the concentration meter purchasing cost of enterprise for concentration measurement result is more accurate and stable.
This device can be under the prerequisite of guaranteeing concentration meter measuring effect, prolongs the life of concentration meter. The device is suitable for occasions with large conveying flow (such as more than 300 m/h), and the effect is more obvious when the conveying flow is large (in mine enterprises, the conveying flow of the ore pulp pipeline is more than 300 m/h in many occasions, and more than 1000 m in some occasions). The principle of this device is with ore pulp reposition of redundant personnel, and the concentration measurement is carried out inside the partly entering concentration of carrying the ore pulp in the pipeline, and the follow-up pipeline of concentration meter entering is bypassed through this current stabilizer to the remaining part. (for example: the flow of the main pulp conveying pipeline in a certain mine site is 300 m/h, the whole year is without rest, the operation is carried out 24 hours a day, the estimated service life of the pipeline type pulp concentration meter is 2 years, after the flow stabilizing device is adopted, the flow of the pulp flowing through the concentration meter is reduced to 120 m/h, the measurement effect is still not influenced, and the estimated service life of the concentration meter can reach more than 4 years and can be prolonged to more than 2 times of the original life).
