Description

Technical Field

[0001] This utility model belongs to the field of supernatant extraction technology, specifically relating to an automatic device for extracting supernatant by detecting the solid-liquid interface. Background Technology

[0002] In the wet synthesis of cobalt tetroxide precursors, sedimentation is frequently used to solidify the precursors. The traditional method involves inserting a siphon tube into the supernatant after sedimentation and siphoning it out. This requires close monitoring of the supernatant level and adjustment of the siphon tube insertion depth as the level drops; otherwise, the suction end may protrude above the liquid surface, allowing air to enter and rendering the siphon ineffective. Furthermore, due to light refraction, the solid-liquid interface is difficult to observe and judge, and the siphon tube may be inserted too deeply into the precipitate layer, causing the precipitate to be drawn away with the supernatant. In addition, for continuous use of the siphon tube to separate supernatant and precipitate from different containers, the siphon tube must be manually filled before each use to ensure siphon operation. This siphon operation is cumbersome, inconvenient, and labor-intensive. Therefore, it is necessary to design a supernatant extraction device that improves the operation. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an automatic device for detecting the solid-liquid interface and extracting supernatant, so as to improve the convenience and efficiency of supernatant extraction, while avoiding the accidental extraction of precipitates.

[0004] This utility model solves the above problems through the following technical means:

[0005] An automatic solid-liquid interface detection and supernatant pumping device includes an ultrasonic solid-liquid interface detector, a pumping rigid tube, a lifting mechanism, a pumping flexible tube, a pumping pump, and a control host. The ultrasonic solid-liquid interface detector is fixedly connected to the pumping rigid tube and is flush with the inlet of the pumping rigid tube. The outlet of the pumping rigid tube is connected to the pumping pump through the pumping flexible tube. The lifting end of the lifting mechanism is fixedly connected to the pumping rigid tube. The control host is electrically connected to the ultrasonic solid-liquid interface detector, the lifting mechanism, and the pumping pump.

[0006] Furthermore, the lifting end of the lifting mechanism is fixedly connected to the liquid extraction tube via a horizontal telescopic rod.

[0007] Furthermore, the lifting mechanism is an electric push rod.

[0008] Furthermore, the inlet and outlet of the liquid extraction tube are respectively located at the bottom and top of the liquid extraction tube.

[0009] Furthermore, the material of the liquid extraction tube is stainless steel.

[0010] Furthermore, the inlet of the liquid-drawing rigid tube is a flared opening.

[0011] This utility model has at least the following beneficial effects:

[0012] This utility model discloses an automatic solid-liquid interface detection and supernatant extraction device, comprising an ultrasonic solid-liquid interface detector, a rigid extraction tube, a lifting mechanism, a flexible extraction tube, a pump, and a control unit. The ultrasonic solid-liquid interface detector is fixedly connected to the rigid extraction tube and flush with its inlet. The outlet of the rigid extraction tube is connected to the pump via the flexible extraction tube. The lifting end of the lifting mechanism is fixedly connected to the rigid extraction tube. The control unit is electrically connected to the ultrasonic solid-liquid interface detector, the lifting mechanism, and the pump. Using this automatic solid-liquid interface detection and supernatant extraction device improves the convenience and efficiency of supernatant extraction while preventing the accidental extraction of precipitates.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Figure 1 This is a schematic diagram of the structure of an automatic solid-liquid interface pumping device provided by this utility model. Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0016] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] like Figure 1 As shown, this utility model discloses an automatic solid-liquid interface detection and supernatant extraction device, including an ultrasonic solid-liquid interface detector 5, an extraction rigid tube 4, a lifting mechanism 2, an extraction flexible tube 9, an extraction pump 10, and a control host 3. The ultrasonic solid-liquid interface detector is fixedly connected to the extraction rigid tube and is flush with the inlet 6 of the extraction rigid tube. The outlet 7 of the extraction rigid tube is connected to the extraction pump through the extraction flexible tube 9. The lifting end of the lifting mechanism 2 is fixedly connected to the extraction rigid tube. The control host 3 is electrically connected to the ultrasonic solid-liquid interface detector 5, the lifting mechanism 2, and the extraction pump 10. In this embodiment, the lifting mechanism is an electric push rod, and the inlet and outlet of the extraction rigid tube are respectively located at the bottom and top of the extraction rigid tube. The extraction rigid tube is made of stainless steel.

[0018] During operation, after the slurry in reactor 1 is stirred, settled, and the solid-liquid interface stabilizes, the lifting mechanism drives the liquid extraction hard tube and the ultrasonic solid-liquid interface detector to simultaneously extend into the liquid surface. The ultrasonic solid-liquid interface detector detects the distance between itself and the solid-liquid interface in real time. This distance is the distance between the liquid inlet of the liquid extraction hard tube and the solid-liquid interface. After the liquid inlet of the liquid extraction hard tube moves down to a preset height (e.g., 3.5 cm) from the solid-liquid interface, the ultrasonic solid-liquid interface detector feeds back the signal to the control host. The control host controls the lifting mechanism to stop descending and simultaneously controls the liquid extraction pump to start, so that the supernatant is extracted through the liquid extraction hard tube and the liquid extraction soft tube. After no more supernatant is discharged from the liquid extraction soft tube, the liquid extraction pump is turned off.

[0019] In summary, the supernatant extraction device based on the automatic solid-liquid interface detection of this application automatically detects the solid-liquid interface and lowers the inlet of the extraction tube to a preset height from the solid-liquid interface. During the extraction process, there is no need to adjust the position of the inlet in real time. Therefore, it effectively improves the convenience and efficiency of supernatant extraction and avoids the accidental extraction of sediment.

[0020] As a further improvement to the above technical solution, the lifting end of the lifting mechanism is fixedly connected to the liquid-drawing rigid tube via a horizontal telescopic rod 8. By adjusting the extension and retraction of the horizontal telescopic rod, the liquid-drawing rigid tube can be moved horizontally to adjust the horizontal position of the liquid inlet of the liquid-drawing rigid tube, thereby changing the liquid suction point. This avoids the liquid suction point being fixed for a long time, which would cause the local position to be affected by the suction force and thus damage the stability of the solid-liquid interface at that local position.

[0021] As a further improvement to the above technical solution, the inlet of the liquid-drawing rigid tube is a flared opening. The flared opening can relatively disperse the suction force, preventing the suction force from affecting the stability of the solid-liquid interface.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
