Abstract

The invention discloses a flocculating agent injecting and adding device for an internal soft silt layer of a silt storage yard or a fill area. The flocculating agent injecting and adding device comprises a motor, a stirring rod, a stirring head and a flocculating agent filling sleeve; the stirring rod is driven by the motor; the stirring head comprises a stirring shaft fixedly connected with a lower end of the stirring rod; a plurality of layers of propeller blades are arranged on the stirring shaft; the flocculating agent filling sleeve is sleeved outside the stirring rod, and two ends of the flocculating agent filling sleeve are hermetically and rotationally connected with the stirring rod respectively via a sealing end plate; a plurality of through holes are arranged on a sleeve wall of the flocculating agent filling sleeve; and a flocculating agent filling soft tube is connected on the sealing end plate on an upper end of the flocculating agent filling sleeve. In the invention, a flocculating agent is injected while rotating and stirring silt so that the uniformity of injection and the use efficiency of the flocculating agent are improved. The flocculating agent injecting and adding device disclosed by the invention has the advantages of a simple structure, light weight, simple and convenient operation, high efficiency and good reliability.

Description

technical field

[0001] The invention relates to a flocculant adding device, in particular to a flocculant injection adding device for a thin soft mud layer inside a sludge stockyard and a dredging reclamation site. Background technique

[0002] In river dredging and dredging projects and sea reclamation projects, the problem of dredging and filling consolidation of soil with high water content will be encountered. For a site filled with high water content silt, if the drainage of the site is not smooth or the clay content of the dredged fill soil is high, the consolidation and settlement will be a long process. During this long process, after a long period of wind, sun and surface evaporation, a thick hard shell layer will be formed on the surface of the dredged fill soil layer, mixed with the rhizome residues of herbaceous plants, making the topsoil have a certain surface However, most engineering monitoring results show that the soil still maintains a high water content a...

Embodiment Construction

[0010] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0011] See figure 1 , a flocculant pressure injection adding device for the thin soft mud layer inside a sludge stockyard and a dredging reclamation site, comprising a motor 1, a stirring rod 7, a stirring head and a flocculant filling sleeve 3.

[0012] The stirring head includes a stirring shaft 6 affixed to the lower end of a stirring rod 7 , and the stirring shaft 6 is provided with multi-layered propeller blades 5 . Each layer of propeller blades 5 is welded on the stirring shaft 6 in order from top to bottom. The stirring shaft 6 preferably adopts a hollow structure, which is light in weight and easy to operate; the lower end of the stirring shaft 6 is preferably an inverted conical shape to facilitate operation and use.
