[0071] Specifically, the liquid level meters 8 in the embodiment of the application are provided by three, which are located near the bottom, the middle and the upper middle of the inner wall of the slurry storage barrel 1, respectively, and the specific positions are not specially limited; in this way, the three liquid level meters 8 can gradually perceive the liquid level state of the slurry in the slurry storage barrel 1, and collect the liquid level height in the slurry data information through the liquid level meters 8.

[0076] Specifically, the slurry monitoring assembly 5 can be a separate 220V power distribution box, and the power distribution box is internally provided with backup power supply, controller and other electronic accessories. The controller is the control module 52, and is provided with wireless and Bluetooth modules.

[0081] Referring to Figures 1-4 Based on the above description, the application provides a slurry preparation station transfer slurry device, and the working principle specifically includes the following:

[0082] When the slurry storage barrel 1 is used, it is necessary to ensure that the first manual valve 22 has been connected with the external slurry supply pipeline, and the second manual valve 32 has been connected with the slurry conveying pipeline; then the first manual valve 22 is opened, the slurry conveyed by the slurry supply pipeline to the slurry storage barrel 1, at this time the slurry can enter the slurry storage barrel 1 through the slurry inlet pipeline 21, at this time the slurry data information needs to be obtained in real time by the slurry monitoring assembly 5;

[0083] For example, when the slurry monitoring assembly 5 receives the signal sent by the liquid level meter 1 located at the inner wall bottom of the slurry storage barrel 1, the control module 52 can drive the driving member 42 to start and stir the slurry; when the liquid surface of the slurry reaches the liquid level meter 2 in the middle of the slurry storage tank 1, the slurry monitoring assembly 5 receives the signal sent by the liquid level meter 2, indicating that the slurry storage barrel 1 has normal slurry supply conditions, and the downstream equipment can start to work, and the second manual valve 32 is opened to ensure the normal flow of the slurry, so after the liquid level meter 2 sends the signal to the control module 52, the control module 52 needs to directly send the signal to the total control system 6 to control the running of the downstream equipment; when the liquid surface of the slurry reaches the liquid level meter 3 in the upper middle of the slurry storage tank 1, it indicates that the slurry storage barrel 1 is full, the liquid level meter 1 sends a signal to the control module 52, and the control module 52 receives the signal and controls the first electromagnetic valve 23 to be closed, and sends information to the total control system 6 at the same time, so that the upstream slurry preparation and slurry conveying equipment are closed; at the same time, since the first flow meter 24, the second flow meter 33 and the density measuring member 25 are also in the working process, the liquid level, the slurry density and the slurry storage amount and other information can also be displayed in real time on the display 9 connected with the control module 52, which greatly improves the automatic control of the whole system, and also can

[0084] effectively prevent the slurry from overflowing, facilitate the control system to control the slurry preparation and conveying to be paused, ensure the organic linkage of the whole system, and improve the automation level of the construction site.

[0085] The above description is only the preferred embodiment of the present application and the explanation of the technical principles. It should be understood by those skilled in the art that the scope of the protection of the present application is not limited to the technical solutions formed by the specific combinations of the above technical features. It should also cover other technical solutions formed by the combinations of the above technical features or their equivalent features without departing from the concept of the present application.
