[0024] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0025] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0026] like Figure 1 As shown, the intelligent quantitative slurry stirring device of the utility model comprises a stirring barrel 1, wherein the stirring barrel 1 has an agitator 2 inside, and the agitator 2 is driven to rotate by a stirring motor 3 located at the top of the stirring barrel 1. The top of the stirring barrel 1 is provided with a dry powder feed port, a water inlet and an auxiliary agent feed port, the lower part of the side wall of the stirring barrel 1 is provided with a finished product outlet, and the bottom of the stirring barrel 1 is provided with a sewage outlet. The dry powder feed port is connected to a dry powder feed screw machine 11, and the water inlet is connected to a filter 4 and a water inlet valve 5 in sequence, and the filter 4 is used to filter impurities in the water.

[0027] The additive feed port is connected to a quantitative additive feeding loss-in-weight scale 6, the finished product outlet is connected to a finished product valve 7, the sewage outlet is connected to a sewage valve 8, and the sewage outlet is used to discharge sewage after cleaning the mixing barrel 1; the bottom of the mixing barrel 1 is connected to a weighing sensor 9, and the weighing sensor 9 is used to weigh the mixing tank in real time and transmit it to the controller; the inner side wall of the mixing barrel 1 is connected to a tuning fork density meter 10, and the tuning fork density meter 10 is used to detect the slurry concentration and transmit it to the controller.

[0028] The stirring motor 3, the dry powder feeding screw machine 11, the water inlet valve 5, the quantitative auxiliary agent feeding loss-in-weight scale 6, the finished product valve 7, the drain valve 8, the weighing sensor 9 and the tuning fork density meter 10 are respectively electrically connected to the controller, and the operation of the entire stirrer 2 is controlled by the controller, wherein the controller is a PLC.

[0029] The driving motor of the dry powder feeding screw machine 11 and the stirring motor 3 are both frequency-converted controlled. The dry powder feeding screw machine 11 is frequency-converted controlled to control the feeding speed and feeding amount; the stirring motor 3 is also frequency-converted controlled to control the stirring speed.

[0030] The discharge port of the dry powder feeding screw machine 11 is connected to the dry powder feeding port through a hose 12, and the quantitative additive feeding loss-in-weight scale 6 is also connected to the additive feeding port through a hose. This design can improve the weighing accuracy, because if a hard connection is adopted, the vibration generated by the dry powder feeding screw machine 11 and the quantitative additive feeding loss-in-weight scale 6 itself will affect the weighing accuracy.

[0031] In addition, the water inlet valve 5, the finished product valve 7 and the sewage discharge valve 8 are all pneumatic ball valves.

[0032] The working principle of this utility model:

[0033] 1) Water is switched on and off through the water inlet valve 5, and the amount of water added is controlled by the weighing sensor 9;

[0034] 2) Add the additives in proportion by using a quantitative additive feeding weight loss scale 6;

[0035] 3) The dry powder enters the mixing barrel 1 through the frequency conversion control of the feeding screw machine;

[0036] 4) After the powder enters the stirring barrel 1, the stirring motor 3 starts stirring;

[0037] 5) The tuning fork density meter 10 detects the slurry concentration in real time. When the set concentration value is reached, stirring is stopped and the finished product valve 7 is opened to release the finished slurry.

[0038] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
