[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figure 1-2 As shown, an intelligent preparation device for indoor multi-aggregate filling slurry includes a cement silo 1, a sand silo 2, and a water silo 3. The cement silo 1, sand silo 2, and water silo 3 are connected to a feeding pipe 11 via a branch pipe 9. The outlet end of the feeding pipe 11 is connected to the inlet of a mixing chamber 6. A weighing scale 20 is installed in both the cement silo 1 and the sand silo 2 to accurately measure the amount of tailings and cement. A first level gauge 18 is installed in the water silo 3 to measure the liquid level in the water silo. A concentration meter 17 and a second level gauge 19 are installed in the mixing chamber 6. The detection signal output terminals of the weighing scale 20, the first level gauge 18, the second level gauge 19, and the concentration meter 17 are connected to a PLC unit 12.

[0021] The mixing chamber 6 is equipped with mixing blades 5 and a mixing motor 10 that drives the mixing blades 5 to rotate.

[0022] The feeding pipe 11 is equipped with a first solenoid valve 4 to control the flow of cement, tailings and water into the mixing chamber. The discharge port of the mixing chamber 6 is equipped with a second solenoid valve 7 to control the flow of the prepared multi-element aggregate into the slurry storage chamber 8. The first solenoid valve 4 and the second solenoid valve 7 are respectively connected to the PLC unit 12 through the first relay 13 and the second relay 14.

[0023] The stirring motor 10 is connected to the PLC unit 12 via an AC contactor 15.

[0024] The PLC unit 12 is equipped with an indicator light 21, an alarm 22, and a touch screen 16. When the values ​​of the weighing scale 20, the first level gauge 18, the second level gauge 19, and the concentration meter 17 are incorrect, the indicator light 21 will light up to indicate an error, and the alarm 22 will start to sound an alarm. The touch screen 16 is used to display measurement data or set preparation data.

[0025] The discharge port of the mixing chamber 6 is connected to the slurry storage chamber 8 via a pipe.

[0026] The outer shells of the cement silo 1, sand silo 2, water silo 3 and slurry storage silo 8 are made of high borosilicate glass, which allows for the visualization of materials.

[0027] In use, the required cement and tailings are placed into cement silo 1 and sand silo 2 respectively, and water silo 3 is connected to an external water source. The slurry mixing ratio is input through the touch screen 16 on the PLC unit 12. Based on the slurry mixing quantity, the PLC unit 12 calculates the mixing water volume. The metering scales 20 built into cement silo 1 and sand silo 2 precisely control the amount of cement and tailings entering mixing silo 6 according to the slurry mixing quantity. At the same time, the first level gauge 18 in water silo 3 precisely controls the amount of water entering mixing silo 6 according to the slurry mixing quantity, and then opens the first solenoid valve 4 to deliver cement, tailings, and water to the mixing chamber. In mixing chamber 6, the stirring motor 10 drives the stirring blades 5 to stir the slurry. The second level gauge 19 in mixing chamber 6 monitors the slurry volume in real time, and the concentration gauge 17 monitors the slurry mass concentration in real time. If all the concentration indicators are normal, cement, tailings, and water are added to the standard level, and stirring continues to ensure that the slurry is mixed evenly. Finally, the second solenoid valve 7 transports the slurry from mixing chamber 6 to slurry storage chamber 8 for laboratory use. When the ratio is incorrect, the indicator light 21 lights up to indicate the error, and the alarm 22 starts to sound. The touch screen 16 is used to display measurement data or set preparation data.

[0028] The device of this invention uses a PLC unit to pre-set the slurry mixing ratio and slurry preparation amount. The PLC unit can automatically calculate the material ratio and accurately control the amount of cement, multi-aggregate and water entering the mixing chamber from the cement silo, sand silo and water silo, so as to obtain a multi-aggregate filling slurry with high accuracy and concentration and homogeneity that meet the experimental mixing ratio requirements.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
