Abstract
The invention relates to the technical field of sewage treatment, in particular to a periphery transmission sludge scraping and sucking machine for a radial-flow secondary sedimentation tank, comprising a working bridge, a central support and a central sludge cylinder, wherein two sludge discharge grooves are arranged below the working bridge and respectively connected with the central sludge cylinder, the bottom of the central sludge cylinder is connected with a sludge outlet pipe, the bottoms of the sludge discharge grooves are respectively connected with a plurality of sludge sucking pipes, the lower ends of all the sludge sucking pipes are respectively connected with sludge sucking nozzles and flat big sucking mouths, and all the flat big sucking mouths are respectively arranged outside the corresponding sludge sucking nozzles. Through the design, an inverted 'V'-shaped scraper device is omitted, and sludge sucking mouths are directly manufactured to the flat big sucking mouths for directly sucking sludge, so as to prevent components from stirring settled sludge, and also reduce the sludge discharge time to avoid bridging phenomenon of the sludge in the pipes, therefore, an original auxiliary compressed air system becomes superfluous, and a sludge sucking device is more concise and reasonable.
Description
Technical field
The present invention relates to technical field of sewage, relate to a kind of center driving scraping and sucking machine, it is applicable to large-scale wastewater treatment plant circumferential water feed, and central water outlet and mud extraction secondary sedimentation tank rise and scrape the precipitating sludge of inhaling at the bottom of pond in second pond.
Background technology
Municipal sewage is processed to the various sedimentation basins that use, even filtering ponds, are mostly with scraping and sucking machine, but in currently available technology, high material consumption, Design of Mechanical Structure is unreasonable, scrapes mud resistance large, and consumed power is large, and operating cost is high, easily has an accident.
Former scraping and sucking machine adopt "eight" shape scraper plate by sludge scraping collection to dredging tube port part, then by mud discharging mouth and be aided with compressed air mud is sucked to mud groove.But actual conditions because of the proportion of activated sludge lighter, good fluidity, in use relies on scraper plate to scrape the collection effect of mud bad, contrary scraper plate can form and stir sludge blanket, sludge discharge effects is also bad; Though have 1-3mm gap at the bottom of cleaning shoe bottom rubber and pond, time one length is often collided with at the bottom of pond because of the reasons such as sedimentation in pond, causes operating load large, and power of motor is large.And the phase mutual interference that service bridge both sides transmission device produces because of reasons such as asynchronous or two sections of driving wheels wearing and tearing are inconsistent.
Summary of the invention
The object of the invention is in order to overcome the deficiencies in the prior art, the Radial Flow Secondary Sedimentation Tank peripheral-traction that a kind of spoil disposal efficiency is high, running resistance is little scraping and sucking machine is provided.
The object of the present invention is achieved like this: Radial Flow Secondary Sedimentation Tank peripheral-traction scraping and sucking machine, comprise service bridge, center support, centre mud cylinder, the below of service bridge arranges twice mud drainage slot, and per pass mud drainage slot is connected with centre mud cylinder respectively, and the bottom of centre mud cylinder connects sludge out pipe; The bottom of per pass mud drainage slot connects respectively several dredging tubes, and the lower end of every dredging tube connects respectively mud-suction nozzle, and the flat-shaped large suction inlet of connection flat is also distinguished in the lower end of every dredging tube, and the large suction inlet of each flat is separately positioned on outside corresponding mud-suction nozzle.
The present invention is by above design, cancelled "eight" shape screeding device, directly mud suction mouth is made to the large suction inlet of flat, directly inhale mud and both avoided the stirring of member to sedimentation mud, also reduced the efflux time of mud, mud is unlikely and in pipe, forms built phenomenon, thereby original supplementary compressed air system just becomes unnecessaryly, mud-sucking device is more succinct reasonable.Flat suction inlet lower edge, apart from the space that must exist at the bottom of pond a mud to suck, makes suction inlet not contact with at the bottom of pond, and this has greatly reduced suction mud resistance, is also a principal element of power decline.
In order to be beneficial to flocculation slaking, strengthen sedimentation effect, the below of centre mud cylinder arranges stabilizing feed well, and inlet opening and apopore are axially set in stabilizing feed well, and inlet opening is lower little large snail spiral shell shape, and the inlet opening of stabilizing feed well connects water inlet pipe.
Service bridge of the present invention comprises two sections of girders, and the inner of every section of girder is hinged with center support respectively, and the outer end of every section of girder is connection for transmission device respectively.3 statically indeterminate problems of former girder have been solved on the one hand; On the other hand whole girder be divided into two sections by transmission mechanism separately, driven after, the phase mutual interference of having avoided both sides transmission device to produce because of reasons such as asynchronous or two sections of driving wheel wearing and tearing are inconsistent.Longer to service time, second pond produces sedimentation and inclination, make that pond top mark is high is inconsistently, the travelling wheel at end carriage place, both sides all can be adjusted contacting of wheel and ground automatically around girder separately and the hinged point of center support, guarantee that travelling wheel can keep good contacting with Chi Ding all the time in whole use procedure, improve the steady reliability of suction dredge to the adaptability of civil engineering environment and operation.
The below of every section of girder of the present invention connects respectively vertical grizzly bar, and vertical grizzly bar mainly plays slow combing cohesion, increases mud compactness.
In order to regulate, inhale mud amount, difference connection traffic control valve on every dredging tube.Static pressure spoil disposal relies on each mouth of pipe valve, and adjust flux to centre mud cylinder is directly discharged.
Per pass mud drainage slot of the present invention arranges respectively several suspension holdfasts outward, and each suspension holdfast is connected with corresponding girder respectively.Overall structure is optimized design, greatly reduces the own wt of suction dredge.Girder, mud drainage slot, dredging tube are linked to be three by rational shape steel bracket to the integral body of a frame shape, make it form a stressed integral body, increased widely rigidity.
