[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example:

[0023] like Figures 1 to 2 As shown, the utility model is a silt clay improvement curing agent testing and detection mixing device, which includes a filling unit, a mixing and stirring unit and a performance testing unit;

[0024] The performance testing unit includes an unconfined compressive strength tester and a moisture content tester; the performance testing unit is an existing technology and is used to measure the performance of the curing product. The performance testing unit is an existing technology and will not be elaborated on here.

[0025] The filling unit includes a box body 1, which is provided with a vertical sealing plate that divides the box body into a first space 2 and a second space 3. The first space 2 and the second space 3 are not connected to each other. The bottoms of the first space 2 and the second space 3 are respectively provided with a first opening and a second opening. The first opening and the second opening are respectively provided with a first mounting seat 4 and a second mounting seat 5. The first mounting seat 4 and the second mounting seat 5 are respectively threadedly connected to a tee 8 via a first connecting pipe 6 and a second connecting pipe 7. The other end of the tee 8 is threadedly connected to a first connecting pipe 9, the other end of which is connected to the mixing unit.

[0026] In this embodiment, the second space 3 is used to store water.

[0027] In this embodiment, a modified curing agent storage box 20 is provided in the first space, and a cross plate 17 is provided in the modified curing agent storage box 20. The cross plate 17 divides the modified curing agent storage box 20 into four sub-storage spaces, namely the first storage box, the second storage box, the third storage box and the fourth storage box. The first storage box, the second storage box, the third storage box and the fourth storage box are respectively provided with a fourth opening, a fifth opening, a sixth opening and a seventh opening at the lower portion. The fourth opening, the fifth opening, the sixth opening and the seventh opening are all connected to a second connecting pipe 18 for diverting different modified curing agents. The other end of the second connecting pipe 18 is placed outside the first connecting pipe 6. That is to say, the length of the second connecting pipe 18 is greater than that of the first connecting pipe 6, and the output end of the second connecting pipe 18 is ultimately inserted into the first connecting pipe 9.

[0028] In this embodiment, solenoid valves are installed in the first, second, fourth, fifth, sixth, and seventh openings. The opening and closing of these solenoid valves control the flow of the improved curing agent and water in the first and second spaces 2 and 3 toward the first and second connecting pipes 6 and 7, respectively. When the water flows through the second connecting pipe 7, it is ultimately injected into the mixing drum 10. Similarly, the improved curing agent also ultimately flows into the mixing drum 10.

[0029] In this embodiment, an electronic scale 19 is provided on the lower side of the improved curing agent storage box 20. The electronic scale 19 weighs the improved curing agent storage box 20, thereby accurately controlling the amount of improved curing agent in each sub-storage box.

[0030] In this embodiment, the mixing unit includes a mixing drum 10. A third opening is provided at the top of the mixing drum 10, and a corresponding sealing plug is provided at the third opening. The third opening is threadedly connected to the first connecting pipe 9. A base 11 is provided on the underside of the mixing drum 10, and the base 11 is threadedly connected to the mixing drum 10, with a sealing gasket provided at the connection.

[0031] In this embodiment, a rotary motor 12 is installed inside the base 11 . The output end of the rotary motor 12 is connected to a rotary shaft 13 via a coupling. A stirring blade 14 is connected to the rotary shaft 13 .

[0032] In this embodiment, an electric heating wire 15 is provided in the wall of the mixing drum 10 , and a temperature sensor (not shown in the figure) and a humidity sensor (not shown in the figure) are also provided inside the mixing drum 10 .

[0033] In this embodiment, a water adding hole 16 is provided on the upper portion of the mixing drum 10 , and the water adding hole 16 is sealed by a sealing plug.

[0034] In this embodiment, an observation window is provided on the wall of the mixing drum 10, through which the mixing conditions inside the mixing drum 10 and the subsequent maintenance conditions can be observed.

[0035] The working principle of the silt clay improvement and curing agent test and detection mixing device:

[0036] Before use, fill the modified curing agent storage box 20 with different types of modified curing agent, and fill the second space 3 with water. Connect the filling unit to the stirring unit, with the four second connecting tubes 18 placed inside the first connecting tube 9. Then, install the base 11 (before installing the base 11, first install the rotary motor 12 inside the base 11, then connect the rotary shaft 13). Connect the installed base 11 to the mixing drum 10. Finally, by controlling the various solenoid valves to precisely adjust the ratio of modified curing agent to water, fill the mixing drum 10 with the modified curing agent and water, and start the rotary motor 12 to stir. Once stirring is uniform, remove the rotary motor 12 and rotary shaft 13 mounted on the filling unit and base 11. Reconnect the base 11 to the mixing drum 10 by threading, and seal the third opening with a sealing plug to create a relatively sealed environment inside the mixing drum 10. Temperature control is then performed using the electric heating wire 15, and humidity control is performed using the water inlet 16 (internal temperature and humidity sensors sense temperature and humidity). Adjustments to varying temperatures and humidity levels are used to simulate different curing conditions.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
