Description

Technical Field

[0001] This utility model relates to the field of mineral slurry settling detection technology, specifically to a simple and reliable thickening tank mineral slurry settling monitoring device. Background Technology

[0002] Currently, monitoring the settling effect of slurry and detecting the depth of supernatant or lower suspension in thickening units such as thickeners typically relies on manual sampling using sampling vessels. However, due to the considerable depth of thickeners, the sampler often needs to be quite long, making operation extremely inconvenient and fraught with problems, such as significant human interference, large sampling errors, the need for frequent operations and multiple sampling points to improve accuracy, the risk of the sampler falling into the thickener, which could cause equipment accidents and disrupt normal production, and the increased safety risks to personnel due to frequent operation.

[0003] Given the limitations of existing detection methods, there is an urgent need for a device that can accurately detect the settling of slurry in thickening tanks in real time, while also addressing the problems of large errors and high safety risks to personnel and equipment associated with traditional detection methods.

[0005] The specific technical solution is as follows: a simple and reliable thickening tank slurry settling monitoring device, including an air-filling main pipe, which is connected to multiple branch pipes of different lengths. The bottom of each branch pipe is connected to the air inlet of an air lifter. The liquid inlet of the air lifter is connected to a sampling pipe. The end of the lift pipe of the air lifter is connected to the feed inlet of a gas-liquid separator.

It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0014] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1 As shown, this embodiment provides a simple and reliable slurry settling monitoring device for thickening tanks, including a main air supply pipe 1. Three branch pipes 2 of different lengths are connected to the main air supply pipe 1, and the bottom of each branch pipe 2 is connected to the air inlet of an air lifter 3. The difference in length of the branch pipes 2 allows the device to sample and monitor slurry at different depths in the thickening tank. A sampling pipe 4 is connected to the liquid inlet of the air lifter 3, and the end of the lift pipe 5 of the air lifter 3 is connected to the feed inlet of a gas-liquid separator 6. An air outlet pipe 7 is connected to the top of the gas-liquid separator 6, and a discharge pipe 8 is connected to the bottom. Of course, this device can be used as follows... Figure 1 The diagram shows three sets of branch pipes 2 of different lengths and their supporting equipment. The number of sets can be increased or decreased as needed to enable sampling and monitoring of slurry at different depths in the thickening tank, thereby gaining a comprehensive understanding of the slurry settling.

[0017] Preferably, a control valve 9 is installed on the upper part of the branch pipe 2 to facilitate the adjustment of the compressed air volume, thereby controlling the lifting speed and volume of the slurry.

[0018] Preferably, the branch pipe 2 is provided with scale lines 10 to facilitate the measurement of the depth of the sampling point and ensure the accuracy of the sampling position.

[0019] It should be noted that all of the above equipment is existing equipment, and the application does not involve structural modifications to this equipment, but only its application.

[0020] Working principle: such as Figure 2 As shown, when monitoring the settling of slurry in the thickening tank is required, the entire equipment is placed at the desired sampling depth within the thickening tank. At this point, each branch pipe 2 extends to a different depth within the thickening tank. Subsequently, the control valve 9 on the branch pipe 2 corresponding to the sampling point is opened, introducing compressed air into the main air supply pipe 1. The compressed air enters the branch pipes 2 of different lengths through the main air supply pipe 1 and then flows along each branch pipe 2 into the air chamber of the air lifter 3. The gas is ejected through the nozzle of the air lifter 3, creating a negative pressure zone at the bottom, thereby drawing the slurry from the thickening tank 10 from the sampling pipe 4 and into the lift pipe 5.

[0021] Inside the riser 5, the slurry is carried upwards by the airflow and eventually enters the gas-liquid separator 6 through the outlet of the riser 5. The gas-liquid separator 6 utilizes the density difference between the gas and the slurry to achieve gas-liquid separation under the action of gravity. The separated gas is discharged from the gas outlet pipe 7 at the top of the gas-liquid separator 6, while the slurry is discharged from the discharge pipe 8 at the bottom. By analyzing the discharged slurry samples, the settling conditions of the slurry at different depths in the thickener can be determined.

[0022] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
