Abstract

The invention relates to a turtle type pump dredge. The turtle type pump dredge is characterized in that the middle part of the dredge is provided with a displacement type slurry pump, a material distributing machine is fixed at the front part of the dredge, and the material distributing machine comprises a bracket, a supporting arm and a dredge pipe; a bench rack which can rotate for 360 degrees is arranged on the rack, the bench rack is connected with a folding supporting arm, the dredge pipe is fixed on the supporting arm and the lower end of the dredge pipe is connected with the outlet of the displacement type slurry pump. The turtle type pump dredge has the advantages: firstly, the slurry transmitted has high concentration with the solid-to-liquid ratio of 80 percent, the water precipitation time is decreased, dredge field is not needed and the thick slurry can be directly loaded into tank vessels and transmitted, thus avoiding the secondary pollution; secondly, the transmission distance is long and can usually come up to 1,000-2,000m; and thirdly, the turtle type pump dredge can run in marsh, shoals and inland rivers and lakes in cities to dispose the domestic garbage and industrial wastes in cities.

Description

Turtle type pump dredge

Technical field

The invention belongs to the water conservancy dredging, specifically be meant desilting equipment.

Background technology

Annual nearly 3,700,000,000 m of China ³Silt go into the sea, wherein major part is deposited on area, river mouth and both sides seashore thereof, the continent is constantly expanded to the sea, coastal beach, marsh have been formed, silt forms a large amount of alluvials in big or small river course in going into extra large process in addition, causes drawing Hong Buchang, for this reason, the annual huge fund that drops into of country is carried out training of river channel improvement.Yet the formula of the strand of China suction at present, bucket wheel formula, drag suction dredger all are to adopt the centrifugal slurry pump mode, and the dredging mode of these machineries has following drawback: the one, and concentration of hydraulic mixture is low, generally between 10～30%, needs suitable spoil disposal field; Otherwise sewage backflow can bring secondary pollution to the surrounding area; The 2nd, conventional strand suction formula or bucket-wheel suction dredger can't be handled life and industrial refuse when city inland river, lake and reservoir desilting, as brick, stone, woven bag, old footwear etc., to such an extent as to can't construct, can only carry out artificial desilting.

Summary of the invention

Problem to be solved by this invention be provide at above-mentioned prior art present situation a kind of be applicable to coastal, the marsh, beach, city inland river, the remote special-purpose desilting equipment of carrying of the thickened drilling fluid in lake, as shown in drawings, the present invention includes hull, adorn on the excavator, hopper, vibrosieve, slush pump, the control room, dynamical system, propeller propeller and supporting leg, it is characterized in that being equipped with amidships the positive displacement slush pump, fix a material distributing machine in the forward quarter, material distributing machine comprises a support, support arm and mud pipe, have on the support one can 360 ° of rotations stand, connect folding type supporting arms on the stand, fixing mud pipe on the support arm, the mud pipe lower end is connected with the outlet of positive displacement slush pump.Operating principle of the present invention and function are: excavator digs out original mud and is deposited on the vibrosieve, the bulk materials that surpasses the compass screen surface yardstick is sifted out, handle separately, thing piece and mud less than the compass screen surface yardstick fall into hopper, sucked by slush pump, through the push-and-pull action of pump, to discharge by mud pipe, mud is transported on the delivery ship or access mud pipe on the bank by the material distributing machine of launching.Propeller of the present invention adopts the twin screw mode, can navigate by water in the water.Supporting leg can be imitated green turtle by land and creep, and is convenient to move and adjust the position; In water, support whole ship during dredging operation, the stability when guaranteeing whole ship operation.This ship adopts the hydraulic leg mode to locate operating water depth scope 0～2.5m.The present invention compares with conventional dredge boat has following advantage:

1, the concentration of hydraulic mixture height of Shu Songing, solid-to-liquid ratio can reach 80%, has reduced precipitation time; Need not the spoil disposal field, can be directly with thickened drilling fluid tank filling Ship Transportation, thus there is not recirculation water, can not produce secondary pollution.

2, this ship can enter marsh, beach, city inland river, lake, can handle urban life, industrial refuse.

3, pumping pressure is big, and fed distance is far away, generally can reach 1000～2000m.

4, displacement pump formula slush pump is simple in structure, and diameter of cylinder is big, seawater corrosion resistance, dependable performance.

Description of drawings

Accompanying drawing 1 is front view of the present invention;

Accompanying drawing 2 is vertical view of the present invention.

Legend: 1, adorn on the excavator, 2, hopper, 3, vibrosieve, 4, the positive displacement slush pump, 5, the control room, 6, mud pipe, 7, dynamical system, 8, support arm, 9, stand, 10, hull, 11, propeller propeller, 12, supporting leg.

The specific embodiment

Hinged supporting leg on four angles of hull is connected with cross cylinder and support oil cylinder between each supporting leg and hull, the action by cross cylinder and support oil cylinder promotes the hull displacement of creeping on land.Twin screw is installed in the afterbody of ship, relies on the propeller can free running in water, relies on supporting leg that ship is propped up during operation, guarantees the operation stability of whole ship.The positive displacement slush pump is installed in the middle part of car, theoretical pumping pressure 7-10Mpa, and theoretical slurry transportation amount 70-100 cubic meter/hour.Fixing one on the material distributing machine support can 360 ° of rotary stand, an end of the head of hinged foldable support arm joint on the stand, be connected with the hydraulic pressure connecting rod between first joint support arm and the rotary stand, support arm is three joints, hinged between the three joint support arms, be connected with hydraulic jack between the support arm, support arm is inwardly folding, 25 meters of three joint support arm lengths of run.Every joint support arm one side is fixed with mud pipe, and mud pipe is staggeredly arranged in the support arm both sides, laterally connects at the support arm joint, guarantees that mud tube can be folding with support arm, 126 millimeters of mud pipe diameters.

Claims

1, turtle type pump dredge, comprise dress on hull, the excavator, hopper, vibrosieve, slush pump, control room, dynamical system, propeller propeller and supporting leg, it is characterized in that being equipped with amidships the positive displacement slush pump, fix a material distributing machine in the forward quarter, material distributing machine comprises support, support arm and a mud pipe, have on the support one can 360 ° of rotations stand, connect folding type supporting arms on the stand, fixing mud pipe on the support arm, the mud pipe lower end is connected with the outlet of positive displacement slush pump.
