[0030] Embodiment:

[0031] As Figure 1 and Figure 2 shown, this embodiment provides a fluid muck automatic mixing and stirring and wastewater recycling device, which includes a muck pit 1, a muck lifting device 2, a high-level muck pit 3, a wastewater collection pit 4, four stirring devices 5, four dust suction devices 6 and a pipeline system 7.

[0032] Furthermore, an built-in platform 15 is horizontally fixed in the muck pit 1.

The bottom plates of the high-level muck pit 3 and the waste water receiving pool 4 are both inclined, and the directions are opposite. The lowest point side of the bottom plate of the high-level muck pit 3 is far from the muck lifting device 2, which is convenient for using the inclination to convey the muck to the mixing device 5 through the muck feeding pipeline 9. The lowest point side of the bottom plate of the waste water receiving pool 4 is close to the muck lifting device 2, which is convenient for using the inclination to flow the waste water into the waste water recovery pipeline 14 and recycle it into the muck pit 1.

[0035] On one side of the upper end of the inner platform 15 far from the muck lifting device 2, four equipment bases 8 are arranged at transverse intervals. The equipment bases 8 are cuboids. In other embodiments, the equipment bases 8 can also be cylinders or cubes. The mixing devices 5 are respectively arranged on the upper ends of the equipment bases 8.

The diameter of the mixing device 5 is the same as the width of the equipment base 8. The dust suction device 6 is a cone and is respectively arranged at the center of the upper end face of the mixing device 5, which is convenient for sucking dust from the muck and avoiding dust pollution to the environment.

[0036] Furthermore, the pipeline system 7 includes a muck feeding pipeline 9, an auxiliary material pipeline interface 10, a mixed muck discharge port 11, a water inlet pipeline interface 12, a waste water discharge pipeline 13 and a waste water recovery pipeline 14.

[0037] As Figure 4 shown, the muck feeding pipeline 9, the auxiliary material pipeline interface 10 and the water inlet pipeline interface 12 are respectively arranged at the top of the mixing device 5. The muck feeding pipeline 9 is arranged adjacent to the auxiliary material pipeline interface 10. The muck feeding pipeline 9 and the auxiliary material pipeline interface 10 are close to the high-level muck pit 3. The other end of the muck feeding pipeline 9 is connected to the bottom of the high-level muck pit 3 and is close to the lowest point of the bottom plate of the high-level muck pit 3. Precise batching can be carried out through the muck feeding pipeline 9 and the auxiliary material pipeline interface 10. The water inlet pipeline interface 12 is far from the high-level muck pit 3 and is close to the mixed muck discharge port 11.

[0038] As Figure 3As shown, one end of the mixed muck discharge port 11 is arranged on one side of the bottom of the mixing equipment 5 away from the muck lifting equipment 2, and the other end is arranged obliquely downward in the larger internal space of the muck pit 1, and the middle part of the mixed muck discharge port 11 is closely attached to the upper edge of the upper end of the built-in platform 15.

[0039] The waste water discharge pipe 13 is connected between the bottom of the mixing equipment 5 and the bottom of the waste water receiving pool 4.

One end of the waste water recovery pipe 14 is connected to the bottom of the waste water receiving pool 4 and is close to the lowest point of the bottom plate of the waste water receiving pool 4, and the other end is connected to the upper part of the transverse partition wall 152 and communicates with the smaller internal space of the muck pit 1.

[0041] In this embodiment, all components are fixed by bolts, which is convenient for disassembly and replacement.

[0042] The working principle of this embodiment is as follows:

[0043] Step 1: Fluid muck lifting

[0044] During the shield tunneling process, the fluid muck generated is lifted to the ground by traditional equipment, poured into the muck pit 1, and then the fluid muck is lifted to the high-level muck pit 3 for storage by the muck lifting equipment 2.

[0045] Step 2: Mixing material addition

[0046] The fluid muck in the high-level muck pit 3 is quantitatively introduced into the mixing equipment 5 by using the muck feeding pipe 9, and mixing materials such as drying agents are added in proportion through the auxiliary material pipe interface 10; at the same time, the dust collection equipment 6 is started to avoid dust pollution.

[0047] Step 3: Mixing and discharging muck

[0048] Start the mixing equipment 5, stir the muck and the mixing materials according to the set mixing duration. After reaching the specified duration, open the discharge valve and discharge through the mixed muck discharge port 11, and store the mixed muck in the larger internal space on the side of the muck pit 1 away from the muck lifting equipment 2.

[0049] Step 4: Cleaning the mixing equipment 5

[0050] After the mixing equipment 5 is used multiple times, clean water is added through the water inlet pipe interface 12 to clean the mixing equipment 5.

[0051] Step 5: Discharging waste water

[0052] After the mixing equipment 5 is cleaned, the generated waste water is collected into the waste water receiving pool 4 through the waste water discharge pipe 13, and then discharged into the smaller internal space on the side of the muck pit 1 close to the muck lifting equipment 2 through the waste water recovery pipe 14.

[0053] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model pertains, based on the idea of the present utility model, several simple deductions, deformations or substitutions can also be made.
