Working principle of example 2:

referring to the attached drawings 1, 2, 3, 4 and 5, the vortex high-speed pulping machine, the weighing sensor and the controller are opened to enter an automatic pulping mode, the controller automatically pumps the clay fine pulp prepared in the embodiment 1 into the pulping barrel 34 from the pulp supply pump along the liquid material inlet 33 by analyzing signals sent by the weighing sensor 41, water enters the pulping barrel 34 from the water supply pump along the liquid material inlet 33 according to the pulping weight ratio, simultaneously the discharge opening of the cement tank and/or the fly ash tank 30 and the screw conveyor 31 are automatically opened, the clay fine pulp enters the pulping barrel 34 from the screw conveyor 31 along the solid material inlet 32 according to the pulping weight, and the mixture enters the pulping state after the batching is finished, at the moment, because the bottom of the pulping barrel 34 is provided with an arc-shaped flow guide channel, the tail end of the flow guide channel is provided with the pulping pump 39 with a dispersed cutter bit, the air cylinder 36 acts on the reversing valve 37, and the reversing valve 37 is adjusted to enable the cement and/or the fly, The slurry obtained by fully mixing and dispersing the clay fine slurry and the water enters a slurry ejection pipe 35 from the other end of a slurry pump 39 through a pipeline, then enters a slurry making barrel 34 from the slurry ejection pipe 35 and is ejected onto the barrel wall of the slurry making barrel 34 to form an ejection effect, cement, fly ash and the like floating on the liquid surface are sucked into a vortex by the vortex generated in the ejection process and then enter the bottom of the slurry making barrel 34, so that the clay fine slurry/the clay cement fly ash fine slurry/the clay fly ash fine slurry can be fully mixed and made into slurry, and the reversing valve 37 is adjusted by an air cylinder 36 after the slurry is made for 2-3 min, so that the prepared qualified clay cement fine slurry/the clay cement fly ash fine slurry/the clay fly ash fine slurry is conveyed. Meanwhile, because the slurry ejection pipe 35 is arranged above the slurry making barrel 34, unqualified clay cement fine slurry/clay cement fly ash fine slurry/clay fly ash fine slurry can be quickly wrapped and mixed with cement and/or fly ash when being ejected by the slurry ejection pipe 35, so that the cement and/or fly ash are not floated on the water surface, the flying of the cement and/or fly ash is reduced, and the subsequent vortex slurry making is more complete. The specific working flow is shown in figure 2

The advantages of this system are: 1. the prepared slurry is not easy to precipitate, the flow resistance is low, and the slurry can be diffused to a farther place under the same pressure condition. The slurry is prepared by mixing the clay fine slurry in the slurry with the cement particles and/or the fly ash, and the dispersibility, uniformity, fluidity and density stability of the clay fine slurry in the slurry reach an ideal state, so that the slurry is more favorable for filling and grouting water-bearing stratum cracks and caves. 2. The dry fly ash is lighter than water, often floats on the water surface and is difficult to pulp, and generally a method for repulping the dry fly ash into wet fly ash after sprinkling water is adopted, the pulping process of the method is complex, air is polluted in the process of changing the dry fly ash into wet fly ash, and the industrial control of the pulping process is not well realized.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
