The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art. In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1 to 3, the sediment collection apparatus 100 of the present utility model includes a sediment collection assembly 1, a sediment discharge pipe 2 communicating with the sediment collection assembly 1, a solidified filter bag 3 for receiving the sediment discharged from the sediment discharge pipe 2, and a floating platform device 4 for supporting the sediment collection assembly 1.

The bottom mud collecting piece 1 is used for pumping out mud to a mud discharging pipe 2, the solidification filter bag 3 is placed on the bank and used for solidification after collecting mud, and the mud discharging pipe 2 is used for discharging mud. In this embodiment, the floating platform device 4 supports the sediment collection assembly 1, and in other embodiments, other supporting devices may be used, and in this embodiment, the method is not particularly limited.

The sludge discharge pipe 2 includes a sludge discharge pipe and a mixing pipe 23 provided in the middle of the sludge discharge pipe. The middle part here does not mean a mathematically middle position, but only if both ends of the mixing pipe 23 are connected with pipes.

The mixing pipe 23 includes a mixing main 231, a flocculant pipe 233 communicating with the mixing main 231, a water feed pipe 232 communicating with the mixing main 231, a first seal to seal the flocculant pipe 233, and a second seal to seal the water feed pipe 232.

The mixing pipe 23 is made of hard material. In this embodiment, the mixing pipe 23 is made of stainless steel.

The main mixing pipe 231 has an inlet end 2311 for introducing sludge and an outlet end 2312 for discharging sludge.

The sludge discharge pipe includes a first pipe 21 connected to the inlet 2311 and a second pipe 22 connected to the outlet 2312, and the second pipe 22 has a length of 100 meters or more. In this embodiment, the first pipeline 21 is used for connecting the sediment collecting assembly 1, the second pipeline 22 is used for discharging the sludge into the solidified filter bag 3, and the length of the second pipeline 22 is greater than or equal to 100 meters, so that the flocculant, water and sludge can be fully mixed.

In this embodiment, the inlet end 2311 is connected to the first pipe 21 by tightening, and the outlet end 2312 is also connected to the second pipe 22 by tightening. In other embodiments, the connection of the main mixing pipe 231 and the sludge discharge pipe 2 may be achieved by screw connection or other means, and the present utility model is not limited thereto. In this way, the mixing main pipe 231 in the present embodiment is more easily matched with the existing bottom mud collecting apparatus 100, and has stronger versatility.

The water feed pipe 232 has a water feed connection 2322 connected to the mixing main 231 and a water feed opening 2321.

The flocculant tube 233 has a flocculant connection end 2332 connected to the mixing main tube 231, and a dosing port 2331.

Along the axial direction of the mixing main pipe 231, the water adding connection end 2322 and the flocculant connection end 2332 are staggered, and the water adding connection end 2322 is closer to the inlet end 2311 relative to the flocculant connection end 2332.

The water pipe 232 is used to add water to the sludge to dilute the sludge so that the subsequent flocculant and sludge can be thoroughly mixed, and therefore the water connection 2322 needs to be closer to the inlet 2311 than the flocculant connection 2332.

The flocculant pipe 233 is used to introduce flocculant into the sludge and is in full contact with the sludge and sewage in the main mixing pipe 231. The flocculant can improve the consolidation efficiency of the sludge, and the sludge diluted by adding water can be more fully mixed with the flocculant, so that the sludge is consolidated more efficiently.

In this embodiment, the number of the flocculant pipes 233 and the number of the water adding pipes 232 are two. The two water feeding pipes 232 and the two flocculant pipes 233 can be used alternatively or can be used simultaneously when a large flow rate is required for dredging. The pipe diameter of the water adding pipe 232 is larger than the pipe diameter of the flocculating agent pipe 233. And one of the flocculant pipe 233 and the water supply pipe 232 may be closed with a first seal and a second seal when the activation is not required.

The fill port 2321 is oriented in the same direction as the inlet port 2311, and the fill port 2331 is oriented in the same direction as the inlet port 2311. This arrangement minimizes the entry of the sludge into the water feed line 232 and flocculant line 233.

According to the mixing pipeline 23, the sludge discharge pipe 2 and the bottom sludge collecting device 100, the mixing pipeline 23 with the water adding pipe 232 and the flocculating agent pipe 233 is arranged, so that water and flocculating agent can be added to sludge, the mixing effect of the sludge and the flocculating agent is improved, and the consolidation efficiency of the sludge is further improved. The mixing pipeline 23 has strong universality, can be matched with the existing sludge discharge pipe 2 and the sediment collection equipment 100, and can greatly improve the consolidation efficiency and consolidation effect of the sludge by a simple structure.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
