Description

Underwater mud throwing device for cutter suction dredger

Technical Field

The utility model relates to a dredge technical field, concretely relates to a device that is used for cutter suction dredger to throw mud under water.

Background

In order to avoid the problem that when the cutter suction dredger throws mud in a specified mud throwing area, mud diffuses everywhere along with ocean current and pollutes the environment, and mud diffuses everywhere along with ocean current and pollutes the environment. There is a need for an apparatus for directing a slurry near the seafloor and through a diffuser opening that reduces the velocity of the slurry and reduces the disturbance to the body of water in the sea. The prior art can not solve the problem of equipment displacement caused by the recoil force of slurry.

In order to solve the above problems, we have made a series of improvements.

An object of the utility model is to provide a device that is used for cutter suction dredger to throw mud under water to overcome the above-mentioned shortcoming and not enough that prior art exists.

An apparatus for underwater mud dumping for a cutter suction dredger, comprising: the sludge discharge pipe support is arranged on the right side of the floating box, the sludge discharge pipe is connected with one end of the elbow, the other end of the elbow is connected with the horizontal short pipe, the horizontal short pipe is connected with the sludge discharge pipe support, and the diffusion port is connected with an outlet at the bottom of the sludge discharge pipe;

wherein, the flotation tank is symmetrical structure, the flotation tank includes: the box body, connect face, top lug and lateral part lug, the box inboard is equipped with connects the face, the box inboard is equipped with semicircular structure's recess, the box top is located to the top lug, the box side is located to the lateral part lug, the flotation tank is through connecting the face symmetric connection.

Furthermore, the upper end of the sludge discharge pipe is provided with a sinking platform.

Furthermore, the connecting surface is provided with an ear plate.

The utility model has the advantages that:

compared with the prior art, the utility model has convenient assembly and disassembly; effectively preventing the mud pipe from shifting due to the recoil force of the mud.

Detailed Description

The present invention will be further described with reference to the following examples. It should be understood that the following examples are illustrative only and are not intended to limit the scope of the present invention.

Example 1

Fig. 1 is a schematic structural diagram of the present invention. Fig. 2 is a schematic structural view of the buoyancy tank.

As shown in fig. 1-2, an apparatus for underwater mud throwing of a cutter suction dredger comprises: the floating box comprises floating boxes 100, a sludge discharge pipe support 200, sludge discharge pipes 300, an elbow 400, horizontal short pipes 500 and a diffusion opening 600, wherein the sludge discharge pipes 300 are arranged at the joints among the floating boxes 100, the sludge discharge pipe support 200 is arranged on the floating box 100 on the right side, the sludge discharge pipes 300 are connected with one ends of the elbow 400, the other ends of the elbow 400 are connected with the horizontal short pipes 500, the horizontal short pipes 500 are connected with the sludge discharge pipe support 200, and the diffusion opening 600 is connected with an outlet at the bottom of the sludge discharge pipes 300;

wherein, flotation tank 100 is symmetrical structure, and flotation tank 100 includes: the buoyancy tank comprises a tank body 110, a connecting surface 120, a top lifting lug 130 and a side lifting lug 140, wherein the connecting surface 120 is arranged on the inner side of the tank body 110, a groove of a semicircular structure is arranged on the inner side of the tank body 110, the top lifting lug 130 is arranged at the top end of the tank body 110, the side lifting lug 140 is arranged at the side end of the tank body 110, and the buoyancy tank 100 is symmetrically connected through the connecting.

The upper end of the sludge discharge pipe is provided with a sinking platform.

The connecting surface is provided with an ear plate.

The utility model discloses simple to operate, it is not an overall structure, but can carry out the split, then field installation. Is convenient for transportation and maintenance. The installation is also very convenient. Only need align 2 flotation tanks 100's the face 120 of being connected, connect the semicircle groove structure on the face, become a circular recess after the combination, then put into this recess with mud pipe 300, mud pipe 300 upper end is equipped with heavy platform 310, and mud pipe 300's flange is located in heavy platform 310, then connects the face 120 and passes through otic placode 121 welded fastening. Then the elbow 400 is connected with the mud pipe 300, the elbow 400 is transversely connected with the horizontal short pipe 500, and the horizontal short pipe 500 is fixed by the mud pipe bracket 200.
