Technical Field

The invention relates to the technical field of sludge treatment, in particular to sludge treatment equipment.

Background

In urban planning, river channels are often planned, particularly in areas with heavy rain, and the river channels are often planned to flow from the interior of cities, so that the discharge pressure of urban accumulated water is relieved by means of the river channels.

I department is in the course of treatment of river silt, earlier by the silt cleaning boat come out with the silt clearance of river bottom, the silt that the clearance was come out is inputed solidification sedimentation tank again after handling such as prefiltering screening and is precipitated, through a period of sediment back, discharges out the water on sedimentation tank upper strata, leaves the water and the silt of bottom, waits for the silt of bottom of the pool to dry the back and takes out the silt of bottom of the pool again and carry out subsequent processing. However, after the sludge is dried in the sun, the sludge is hardened, which causes great obstruction to the extraction of the sludge, and the sludge is also mixed with river sand, so that the problem of sand deposition at the lower layer of the sludge is serious.

An equipment is urgently needed to solve the problems of sludge hardening and sand deposition.

Disclosure of Invention

The invention aims to provide sludge treatment equipment, which realizes the integrated operation of crushing, extracting and screening hardened sludge, thereby solving the problems of hardening and sand sedimentation of the sludge.

The technical purpose of the invention is realized by the following technical scheme: the utility model provides a silt treatment facility, includes sedimentation tank body, sedimentation tank body is put on the shelf and is equipped with the support, be provided with on the support silt smash the mechanism in silt smash the mechanism after carry out the extraction mechanism that extracts to the silt of smashing and heavy sand and to the screening mechanism that silt and heavy sand that the extraction mechanism was taken out carried out the screening.

Through adopting above-mentioned scheme, when handling the silt to sedimentation tank body bottom of the pool, smash the mechanism by the silt earlier and smash hardened silt, sun-dried silt is approximately powdered after being broken up, then silt after smashing and sediment are extracted by the powerful of extraction mechanism, the silt of smashing and sediment are extracted and are carried and filter in the screening mechanism, thereby separate silt and sediment, the sand of sieving out is carried spacious place and is stacked, and the silt of sieving out is then carried into the sedimentation tank and is carried out operations such as subsequent filter-pressing, thereby realize the smashing of hardened silt, extraction and screening integration operation, solve the silt and harden and sediment problem.
