Abstract
The invention belongs to the technical field of environmental protection, and in particular relates to a sediment mechanical stirring device for a drainage pipeline. From top to bottom, the shell of the device is composed of an output shaft, a rotor base, a rigid body, a rigid body base, a rigid body rear base and a fixed station. The mechanical stirring device is arranged on fixed or mobile equipment; by measuring mud thickness of the pipeline, the advancing speed of the mobile equipment is selected, so that a stirring power value of unit mud amount is guaranteed and the lowering of sediment flushing shear force is achieved; under the condition of the designed flow rate of the pipeline, sediment in the drainage pipeline is flushed to the downstream side of a drainage pipeline system until to a sewage treatment plant, so as to avoid treatment on the sediment removed from the interior of the drainage pipeline; therefore, the mechanical stirring device simplifies an operation procedure and meets demands on maintenance of an urban drainage pipe network system.
Description
Technical field
The invention belongs to environmental technology field, be specifically related to a kind of drainage pipe deposit mechanical agitation device.
Background technology
At present, dry river basin, inner city, cities in China is after substantially completing sewage network construction and section dirty pollution treatment, water quality is significantly improved, but water quality of river leading indicator still can not be stablized and reaches functional areas standard, especially, before and after flush period, city along the line, master stream, inner city rainfall pumping station Its Adjacent Waters of having stable political situation still occurs black smelly often.The secondary pollution factor in this phenomenon shows some in river course black smelly stage, along with cutting carrying out of dirty pollution treatment and dredging waterway thereof, showing especially gradually and stablizing the subject matter with continuative improvement for affecting inner city water quality of river.
Cause the basic reason of this protrusion phenomenon mainly due to: (1) the dirty hybrid junction of separate flow system rain causes sewage to put river polluting, and find according to investigation in 2008, the ratio of inspection shaft or well of going out that river for transporting grain to the capital informer times river rising in Ningxia and flowing into central Shaanxi, Shanghai City drainage system has hybrid junction problem reaches 69%; (2) combined flow system early-stage rainwater and Municipal pumping stations are found time in advance to cause and are put river and pollute, and when putting river, COD maximum concentration is more than 2000mg/L, causes river again black smelly.Cause high load capacity impact the reason polluted be point/drainage system pipe network in, the discharge of sewage in dry days pipelines is little, and flow velocity is low, and the suspended solid in sewage is deposited at the bottom of pipe; And when rainfall, flow increases suddenly, the deposit in pipeline is washed, and enters river and river water quality is deteriorated.Therefore, need clean pipeline deposit, avoid making the deposit in drainage pipe flow into river course in rainy season.
Current drainage pipe deposit cleaning technology mainly comprise manually draw clearly, grab mud car, vacuum inhale mud, inlet for stom water basket, push rod and bull stick dredging, jetting dredging, winch dredging, waterpower dredging.Front four kinds mainly for the deposit in manhole and inlet for stom water, latter four kinds is for the deposit in drainage pipe, and distinct methods is applicable to different occasion and for different deposits.But these methods are not have that labour intensity is large or cleaning is clean, exist exactly and need deposit to clear out drainage pipe, row relax of going forward side by side, in order to avoid produce secondary pollution, thus there is the inconvenience of many uses.Therefore, for meeting in urban drainage pipe network system the technology needs managing, safeguard, develop a kind of drainage pipe deposit mechanical agitation device, the deposit making to be bonded on tube wall or be deposited at the bottom of pipe is loosening, wash away shearing force to reduce, ensure under normal pipe design flow velocity or lower shearing force condition, by deposit punching to drainage pipe downstream, until Wastewater Treatment Plant, seem particularly necessary.
