Silt alluvial in the sand trap of power station and water works, the small reservoir of retaining, reservoir, navigation channel and the harbour is relevant industries problems very deeply concerned.Existing mud cleaning equipment is drawn with system can be divided into indirect or direct two kinds of different desilting patterns.Directly the desilting pattern be by dig, shovel, mode such as strand directly moves mud, the mud water content that is handled upside down is relatively low.The desilting pattern is then loosening with mud earlier by the mode of harrowing, cutter is cut or water under high pressure dashes indirectly, and then with the mud suction, the mud water content that is handled upside down is higher relatively.Directly the relevant device complex structure of desilting pattern, volume is big, investment is high, construction plant that require is also big, and often mud does not adopt by line transportation, may be along the certain environment pollution of Cheng Zaocheng in the handling process.And the relevant device structure of desilting pattern is simple relatively indirectly, volume is less, invest lower, as not to be subjected to construction plant size restriction, and often by line transportation mud, can not cause environment pollution in the handling process.Because the sedimentation time of mud is longer usually, forming hardens is not easy by direct intake duct mud, if sand content is more in the mud, also is not easy by direct intake duct.Even be inhaled into the mud of pipeline, if become piece agglomerating, then increase the load of line transportation, reduce the conveying capacity of system, and easily cause line clogging.Running into has in the mud than bough or clod, and intake is blocked easily.Just there are the problems referred to above in rake in the indirect desilting pattern so far and the cutter pattern of cutting, and water under high pressure punch die formula then should not be carried out usually under water.

Three, utility model content

The purpose of this utility model is the defective that overcomes common indirect desilting pattern, the loosening under water mechanism of employing novel concept mud, thus even, the defeated mud concentration height of a kind of concentration of hydraulic mixture is provided, is not easy to cause pipeline and intake to stop up and water need be put dried mud suction cleaning plant.This novel purpose is achieved in that a kind of mud suction cleaning plant, comprises dredging tube road, dredge pump, spoil disposal conveyance conduit, it is characterized in that also having and the joining soil-suction head in described dredging tube road; Have the rigidity watertight shutter of aperture on also having, this watertight shutter connects firmly in the soil-suction head outer end; Also have a plurality of vibrating heads that are fixedly installed on this watertight shutter.

Described vibrating head is the dither rod.

Also be provided with the flexible edge skirt on the circumferential outer edge of described watertight shutter.

From such scheme as seen, mud of the present utility model is loosening under water is to be finished by the high-frequency vibration rod of existing ready-mixed concrete.The excellent high-frequency vibration that produces of high-frequency vibration is loosening with underwater sludge, and makes it to join the mixed basic mud uniformly that stirs into mutually with water.Have under the situation of thick cobble in the mud bottom, cobble still can be difficult for being inhaled in the conveyance conduit bottom sinking to all the time with the mud sorting.

Basis is suitable novel mainly to be made up of shock club (particularly dither rod), soil-suction head, watertight shutter, dredging tube road, spoil disposal conveyance conduit, dredge pump etc., generally can be installed on raft or the ship and use.The high-frequency vibration rod is installed on the watertight shutter of soil-suction head, inserts in the mud during work.Watertight shutter mainly is the sediment concentration that contains that the amount that stops the current on mud top directly to be sucked conveyance conduit too much reduces to enter conveyance conduit.Spreading all on the watertight shutter has aperture, and the outside skirt can adopt flexible edge strip.Aperture allows the part current to flow into watertight shutter to mix with the mud ginseng down, and form water with and the eddy current ginseng of mud mix, increase the uniformity of concentration of hydraulic mixture, it is interior and cause soil-suction head to be blocked to prevent that whole soil-suction head is inhaled into mud.The flexible edge skirt stops too much water to enter from the soil-suction head periphery.

The mud conveying pipeline that picks out from soil-suction head is received the dredge pump water inlet end on the raft, and the water side of dredge pump connects conveyance conduit again, and mud is sucked pressurized delivered by water pump, with slurry transportation to the discharging destination.From the conveyance conduit that dredge pump picks out, can allow it sink under water, extend disembarkation then, slurry transportation is to the discharging destination the most at last.

This is novel, and to have a concentration of hydraulic mixture even, and defeated mud concentration height is not easy to cause pipeline and intake to stop up, and need water put to do to carry out the advantage that mud is got rid of again.
