Problems solved by technology

At present, there are many dredging devices that regularly remove silt from the bottom of rivers and lakes, but most of the silt removed by these dredging devices is disposed of by burial, but there is a risk of heavy metal elements entering the groundwater body again after burial, so If the sludge after removal can be directly used again, a virtuous circle will be formed

Embodiment 1

[0035] Such as figure 1 Shown:

[0036] A sludge treatment device for water conservancy projects, comprising a conveying device, a stirring chamber, a conveying pipeline part, a sludge filtering chamber, a mud mixing and drying part, a mixing and granulating chamber and a ceramsite heating chamber.

[0037] The conveying device includes a mud inlet, a dredge pump arranged at the mud inlet, and a crushing and conveying shaft arranged at the rear end of the dredge pump. The crushing and conveying shaft is in the form of a single helical knife arranged on a rotating shaft. The sludge delivered by the pump is broken up and conveyed to the inlet of the mixing chamber.

[0038] The inside of the stirring chamber is provided with a vertically penetrating stirring shaft and high-pressure water nozzles arranged at the entrance of the stirring chamber and at both ends of the stirring shaft, and the outlet of the stirring chamber is arranged at the bottom of the stirring chamber.

Abstract

The invention relates to a sludge treatment apparatus for a water conservancy project. The sludge treatment apparatus comprises a transport apparatus, a stirring chamber, a transport pipeline part, a sludge filter chamber, a sludge mixing and drying part, a mixing and granulating chamber and a ceramsite heating chamber. By arranging various parts, the sludge treatment, the ceramsite preparation from sludge and the ceramsite forming can be continuously carried out, so that not only can the sludge containing heavy metal be removed and the secondary pollution of the sludge to a water body be avoided, but also heavy metal elements are secondarily utilized for the ceramsite, and the harmful sludge can be actually turned into benefit.

Description

technical field [0001] The invention belongs to the field of mud removal in water conservancy projects, and in particular relates to a sludge treatment device for water conservancy projects. Background technique [0002] The bottom of rivers and lakes often accumulates a lot of silt, which is often enriched with a large amount of heavy metal elements due to short-term or long-term water pollution. These heavy metal elements will enter the water body again after the water pollution is eliminated, re-pollution Water body. At present, there are many dredging devices that regularly remove silt from the bottom of rivers and lakes, but most of the silt removed by these dredging devices is disposed of by burial, but there is a risk of heavy metal elements entering the groundwater body again after burial, so If the cleared sludge can be directly used again, a virtuous circle will be formed. Contents of the invention [0003] The invention proposes a sludge treatment device for w...
