[0002] During the alumina production process, the process of slurry sampling, as an important means to monitor the stability of the production process and product quality, has long been that workers hold a syringe to extract for sampling. This method is time-consuming and laborious, with complex operations and safety hazards such as chemical burns and mechanical injuries. Especially in processes with high solid content, plugging is likely to occur during sampling, resulting in difficult sampling and the need to rely on external tools for dredging, greatly increasing the operation risk and work intensity. Content of the Utility Model

[0003] Therefore, the purpose of the utility model is to provide an automatic slurry sampling device during alumina preparation. Through the mutual cooperation of the sampling support component, the moving component, and the automatic sampling component, automatic quantitative sampling is realized, and during the sampling process, sampling stirring is carried out in real time, which is applicable to sampling of various slurries with different concentrations. After the sampling work is completed, it is automatically cleaned for the next sampling to avoid sampling blockage.

[0004] To solve the above technical problems, according to one aspect of the utility model, the following technical solution is provided: An automatic slurry sampling device during alumina preparation, comprising:

[0005] A sampling support component, the sampling support component includes a set equipment body plate, a cleaning cup, a liquid discharge cup, and a sampling cup arranged on the top surface of the equipment body plate;

[0006] A moving component, the moving component includes an X-truss arranged on the top surface of the equipment body plate, an X-direction stepping motor arranged at the position of the X-truss, a drag chain arranged on the side of the X-direction stepping motor, a connecting plate connected to the X-truss, a Z-truss connected to the connecting plate, a Z-direction stepping motor arranged at the position of the Z-truss, a truss sliding plate connected to the Z-truss, and a workbench fixing plate connected to the truss sliding plate;

[0007] An automatic sampling component, the automatic sampling component includes an installation box connected to the workbench fixing plate, an upper composite plate fixed at the top end of the installation box, a stepping motor arranged on the top surface of the upper composite plate, a piston rod connected to the output end of the stepping motor, a sampling syringe sleeved outside the piston rod, a needle pipeline communicated with the sampling syringe, and a liquid suction needle communicated with the needle pipeline.

[0008] As a preferred embodiment of the automatic slurry sampling device in the alumina preparation process of the present utility model, four mounting boxes are provided, and corresponding upper closing plates, stepping motors, piston rods, sampling syringes, needle pipelines, and liquid suction needles are arranged at the positions of each mounting box.

[0009] As a preferred embodiment of the automatic slurry sampling device in the alumina preparation process of the present utility model, the piston rod slides along the inner side of the sampling syringe.

[0010] A rubber stopper is connected to the surface of the piston rod.

[0011] As a preferred embodiment of the automatic slurry sampling device in the alumina preparation process of the present utility model, a stirring assembly is further included. The stirring assembly includes a rotating motor arranged inside the mounting box, a connecting rod connected to the output end of the rotating motor, and stirring blades fixed to the bottom surface of the connecting rod.

[0012] As a preferred embodiment of the automatic slurry sampling device in the alumina preparation process of the present utility model, the stirring assembly further includes a light-axis limiting frame fixed to the inner side wall of the mounting box.

[0014] Compared with the prior art, the advantages of the present utility model are as follows:

During the sampling process, sampling and stirring are carried out in real time, which is applicable to the sampling of various slurries with different concentrations.

[0016] In specific use, the X-axis stepper motor cooperates with the X-truss to achieve the horizontal movement of the Z-truss, and the Z-truss cooperates with the Z-axis stepper motor to achieve the vertical movement of the truss sliding plate, thereby realizing the up and down movement of the workbench fixing plate. During the working process, when the truss sliding plate moves downward, it drives the liquid suction needle head to shift into the sampling cup. At this time, the stepper motor drives the piston rod to move upward. When the piston rod moves upward, suction is performed, and the liquid to be sampled flows into the needle head pipeline through the liquid suction needle head and is finally sucked into the sampling syringe. During the liquid sampling process, the rotary motor drives the connecting rod to rotate, and the connecting rod drives the stirring blade to rotate, so that sampling is carried out while stirring, which is suitable for sampling slurries with different concentrations. The stepper motor controls the displacement length to perform quantitative liquid sampling. After the sampling is completed, the truss sliding plate moves upward, and the X-truss moves horizontally, driving the liquid suction needle head to move to directly above the liquid discharge cup. At this time, the liquid suction needle head moves downward into the liquid discharge cup, and the stepper motor drives the piston rod to push, so that the piston rod pushes out the sample liquid for liquid discharge and filtration. After the liquid discharging is completed, the liquid suction needle head moves upward and horizontally to the position of the cleaning cup, and the liquid suction needle head moves downward into the cleaning cup for cleaning to facilitate the next sample sampling.
