Description
Technical Field
The invention relates to a sludge treatment device. Particularly, the underwater sludge solidified soil continuous pouring device is used for conveying sludge solidified soil which is fished from rivers and lakes to underwater positions needing to be filled after dehydration and solidification.
Background
At present, the sludge produced by dredging rivers and lakes has two main purposes: one is that the silt is added with the solidified material and mixed to prepare the solidified soil which is used in backfill, road and greening engineering; the other is poured to the required position of the bottom of the river or lake. The method for pouring the water bottom comprises the steps of arranging cofferdams in rivers and lakes to be poured and draining water in the cofferdams. And then backfilling the solidified soil of the silt to a required position in the cofferdam. And finally, opening the cofferdam and draining water into the cofferdam. The method sequentially needs the steps of arranging the cofferdam, draining water in the cofferdam, pouring silt solidified soil, opening the cofferdam and discharging water into the cofferdam and the like, so that the construction steps are more, the engineering quantity is large, the needed fund is more, and the treatment efficiency is low.
Disclosure of Invention
The invention aims to provide an underwater continuous pouring device for sludge solidified soil. By adopting the device, the construction steps can be reduced, the engineering quantity is reduced, the capital investment is reduced, and the treatment efficiency is improved.
The above problems to be solved by the present invention are realized by the following technical solutions:
the invention relates to an underwater continuous pouring device for sludge solidified soil. The top of the stirrer is provided with a feed inlet and a sludge inlet, and the bottom of the stirrer is provided with a soil discharge port; a curing material bin and a mud bucket are arranged above the stirrer. The bottom of the solidified material bin and the bottom of the mud bucket are respectively provided with a discharge hole and a mud outlet, and the discharge hole and the mud outlet are respectively communicated with the feed inlet and the mud inlet through a first valve 1 and a second valve 2. The method is characterized in that: a solidified soil bin is arranged below the stirrer, and a third valve 3 is arranged between the top of the solidified soil bin and the soil discharging opening of the stirrer. A plunger pump is arranged below the solidified soil bin, and a fourth valve 4 is arranged between the inlet of the plunger pump and the bottom of the solidified soil bin. One side of the plunger pump is provided with a mud conveying pipe. The upper end of the mud conveying pipe is communicated with an outlet of the plunger pump through a fifth valve, the lower end of the mud conveying pipe extends into a position needing to be poured underwater, and an air compressor and an air tank are arranged on one side of the upper end of the mud conveying pipe. The air outlet of the air compressor is communicated with the air tank, and the outlet of the air tank is communicated with the outlet of the fifth valve and the upper end of the mud conveying pipe by virtue of the sixth valve.
The blender is a wheel blender.
And the third valve, the fourth valve and the fifth valve are all air valves.
According to the scheme, the solidified soil bin is arranged below the stirrer, and the third valve is arranged between the top of the solidified soil bin and the soil discharging opening of the stirrer. A plunger pump is arranged below the solidified soil bin, and a fourth valve is arranged between the inlet of the plunger pump and the bottom of the solidified soil bin. One side of the plunger pump is provided with a mud conveying pipe. The upper end of the mud conveying pipe is communicated with an outlet of the plunger pump through a fifth valve, the lower end of the mud conveying pipe extends into a position needing to be poured underwater, and an air compressor and an air tank are arranged on one side of the upper end of the mud conveying pipe. The air outlet of the air compressor is communicated with the air tank, and the outlet of the air tank is communicated with the mud conveying pipe adjacent to the fifth valve through the sixth valve. When the device works, the sludge solidified soil sent by the stirrer enters the solidified soil bin. And the sludge solidified soil in the solidified soil bin is conveyed into the plunger pump through the fourth valve, and the plunger pump and the fifth valve continuously convey the sludge solidified soil to the position needing pouring at the bottom of the water. When the conveying distance is long, the mud conveying pipe is long and the conveying resistance is large, compressed air is sent into the mud conveying pipe in a pulse mode by means of the air compressor, the air tank and the sixth valve to assist in conveying the solidified soil in the mud conveying pipe to the water bottom. Compared with the prior art, the steps of setting a cofferdam, pumping water in the cofferdam, opening the cofferdam to discharge water into the cofferdam and the like are not needed, so that the construction steps are greatly reduced, the engineering quantity is reduced, the capital investment is reduced, and the treatment efficiency is improved.
