Description

A kind of flat flow suction dredge

Affiliated technical field

The utility model relates to the soil pick-up mud device in a kind of sewage disposal technology, exactly is a kind of flat flow suction dredge that is used to draw mud at the bottom of the settling pool.

Technical background

Suction dredge is a visual plant of drawing the mud of precipitation in Industrial Wastewater Treatment processes such as papermaking.Mainly form by devices such as submersible sewage pump, sludge pipe, drivings.In recent years, China is used for the flat flow suction dredge of sewage disposal greatly to there being two kinds, and a kind of is that submersible sewage pump is suspended above the underwater sludge blanket with inhaling the mud parts, and the top is connected with crane device.Come and go the operation of suction mud by driving mobile drive mud-sucking device under water in orbit.But a plurality of suction mud mouths need be set generally, could to guarantee to inhale mud thorough for the mud-scraping apparatus that also will be provided with simultaneously that has, the desired height that submersible sewage pump can only be risen on the water surface when the maintenance maintenance overhauls, and to the maintenance maintenance of under water dredging tube etc. as mediation or when removing inner mud, the sewage that then needs to drain in the pond carries out at the bottom of the pond.Another kind is the float-type suction dredge, and promptly floating drum hangs mud-sucking device and moves and inhale mud on the water, crosses to hang down because of water level and just can't work, and operates in addition, adjusts inconvenience, inefficiency, underwater units maintenance difficult and being eliminated gradually.

The utility model content

The utility model purpose is for overcoming the deficiency of background technology, provide a kind of working stability efficient, the maintenance submersible sewage pump of both can under the situation of not arranging waste water in the pond, having sling easily, also can be simultaneously to the remove contamination flat flow suction dredge of maintenance of mud of dredging tube, its technical scheme is: a kind of flat flow suction dredge, by having drive motors, the driving of rail wheel, suspension bracket, sludge pipe, diffusion chamber, submersible sewage pump, dredging tube is formed, the driving below is fixed with suspension bracket, the suspension bracket bottom is placed with dredging tube, the dredging tube middle part connects submersible sewage pump, submersible sewage pump is connected to sludge pipe, sludge pipe top is 90 degree secured in parallel on the driving roof beam structure, and its outlet is positioned at driving one end and links to each other with diffusion chamber.

Suspension bracket is welded into a cuboid framework by 4 vertical steel pipes with 4 parallel channel-section steels that are positioned at the bottom.

Dredging tube is a H type double pipe structure, and by middle communicating pipe intercommunication, each side of dredging tube is with respect to the other limited post that is welded with respectively in the position of the vertical steel pipe of suspension bracket, its effect is both can guarantee to remain plumbness when promoting the mud-sucking device of being made up of immersible pump, dredging tube under water and rise to desired height smoothly, so that maintain operation, can guarantee the accurate fixed position of dredging tube again in the suspension bracket bottom.4 external port of dredging tube all seal, and evenly leave some circular mud-suction holes below dredging tube, can guarantee to inhale mud evenly, thoroughly.

On the dredging tube and submersible sewage pump top is welded with suspension ring respectively, and the jack lower end is fixed on the suspension ring, and the upper end is fixed on the driving roof beam structure, promotes submersible sewage pump and dredging tube when being used to maintain.

The beneficial effect of this utility model is: it is effective to inhale mud, is convenient to the full maintenance maintenance, and fault rate is low, can effectively prolong service life of equipment.

The specific embodiment

The utility model is described in further detail for the contrast accompanying drawing below, a kind of flat flow suction dredge of the utility model, form by the driving 2 that has drive motors, rail wheel 1, suspension bracket 3, sludge pipe 6, diffusion chamber 7, submersible sewage pump 5,

dredging tube

4,2 belows of driving a vehicle are fixed with suspension bracket 3, suspension bracket 3 bottoms are placed with dredging tube 4, dredging tube 4 middle parts are connected with submersible sewage pump 5, the mud mouth of submersible sewage pump 5 is connected to sludge pipe 6, sludge pipe 6 tops are 90 degree secured in parallel in driving 2, and its outlet is positioned at driving 2 one ends and links to each other with diffusion chamber 7.

Suspension bracket 3 is welded into a cuboid framework by 4 vertical steel pipes with 4 parallel channel-section steels that are positioned at the bottom, the dredging tube 4 of H type places suspension bracket 3 bottoms, dredging tube 4 each side are with respect to the other limited post that is welded with respectively in the position of the vertical steel pipe of suspension bracket, and purpose is to guarantee vertical-lift and accurate in the position of suspension bracket 3 bottoms.4 external port of dredging tube 4 are all shut, and evenly leave some circular mud-suction holes 9 below dredging tube 4, and these mud-suction holes 9 are complementary with the suction mud mouth sectional area of submersible sewage pump 5, can guarantee to inhale mud evenly, thoroughly.When inhaling the mud operation, driving 2 travel switches by drive motors, rail wheel 1, track two ends move back and forth along the parallel track on the pool wall of settling pool both sides, drive suspension bracket 3 and make submersible sewage pump 5 and dredging tube 4 whole moving, simultaneously, mud at the bottom of the pond promptly is drawn into sludge pipe 6 evenly, up hill and dale by some mud-suction holes 9 of submersible sewage pump 5 by dredging tube 4 bottoms, again through promoting the diffusion chamber 7 of laggard 2 one ends of going into to drive a vehicle, be discharged in the mud canal 12 after the diffusion decompression by diffusion chamber 7, enter next treatment process.One secondary suspension bracket 3 and submersible sewage pump 5, a cover dredging tube 4 are one group of mud-sucking device, and each driving 2 can be hung many group mud-sucking devices according to the design of settling pool width.

Be convenient for maintaining, the top that reaches submersible sewage pump 5 on dredging tube 4 is welded with suspension ring 10 respectively, jack 11 lower ends link to each other with suspension ring 10, the upper end is fixed on the roof beam structure of driving 2, when needing maintenance, unclamp the horizontal adpting flange of sludge pipe 6 earlier, by jack 11 desired height is arrived in mud-sucking device vertical-lift under water then, can be to submersible sewage pump 5 maintenances such as mud of overhauling or dredging tube 4 removed contamination, because of the position-limiting action of limited post 8, when slinging mud-sucking device, can remain vertical-lift and accurate return; Also can use the submersible sewage pump 6 that has the self coupling hook, be characterized in as long as accurate positioning, give submersible sewage pump 5 certain to upper pulling force the time, its pump housing will break away from voluntarily with sludge pipe 6 the docking couple state of flange to be separated, when submersible sewage pump 5 resets, can under the automatic coupling of self coupling hook, connect by flange automatic and sludge pipe 6 again, and under the deadweight effect of the pump housing and dredging tube 4, engage closely, when maintenance, just can unclamp the horizontal adpting flange of sludge pipe 6 like this, directly submersible sewage pump 5 and dredging tube 4 are sling simultaneously, make the maintenance operation more convenient, fast, and, can alleviate the load of slinging greatly owing to there has not been the weight of sludge pipe 6.
