Description

Small sludge-removing vessel

The utility model relates to the small desilting machine of a kind of floating type from the pool, ditch and harbour of boat, limit suction, limit row's operation.

Mobile in pump of existing silt remover, mud is to flow out after passing blade after entering in the pump, because mud will pass blade, blade can stop up mud on the one hand, influence the unimpeded of runner, on the other hand, mud also can damaged blade or other part of the pump housing, increased maintenance, reduced service life, route speed, tensile force for boat column and desilting concentration three well do not coordinate, and desilting concentration and efficient are not high, simultaneously, the manoevreability on land is also bad.

The purpose of this utility model is exactly a kind of desilting efficiency data height of providing at above-mentioned situation, continue to flow, small-sized dredger easy to maintenance is shifted and manipulates on land.

Solution of the present utility model is: be mobile vehicle with the small hull, form the hull navigation system by change speed gear box, tailing axle, propeller, form suction mud system by mud pump, mud sucking disk, suction, row's mud pipe, be connected with diesel engine by belt-driving, wherein on the axial water inlet of mud pump, be connected with the sludge suction rubber pipe that links to each other with mud sucking disk, be connected with sludge out pipe with the radially outlet of water inlet bonded assembly pump case, be reduced to beyond the radially outlet of pump case after being contained in the impeller on the pump shaft, its detailed content is described below referring to accompanying drawing:

Referring to Fig. 1,2, the structure of small-sized dredger of the present utility model is to be mobile vehicle with small hull (1), by change speed gear box (6), tailing axle and propeller (13) are formed the hull navigation system, by mud pump (3), mud sucking disk (15), dredging tube (7) and row's mud pipe (5) are formed suction mud system, be connected with diesel engine (4) by belt-driving, open diesel engine (4), drive mud pump (3) by belt-driving on the one hand, vexed suction effect by mud sucking disk (15) is with the mud inspiration, and from row's mud pipe (5), discharge, make change speed gear box (6) drive tailing axle and propeller (13) make hull (1) lowsteaming by belt-driving on the other hand, mud sucking disk (15) is moved and forming movement in silt seam at the bottom of the pool with hull (1), feature of the present utility model is to be connected with the sludge suction rubber pipe (7) that links to each other with mud sucking disk (15) on the axial water inlet of mud pump (3) (17), be connected with sludge out pipe (5) with the radially outlet of water inlet (17) bonded assembly pump case (18), be reduced to beyond the radially outlet of pump case (18) after being contained in the impeller (19) on the pump shaft (22), as shown in Figure 3, be in beyond the whirl chamber of pump case (18) owing to impeller (19) like this, clear in the runner of whirl chamber, runner is unimpeded, mud axially the advancing that sucks from pump case (18), radially go out, resistance is little, improve desilting efficiency data, also reduced the partial failure of mud pump (3).Impeller of the present utility model (19) adopts plank frame, as Fig. 4, shown in 5, primary blades (19A) is a chevron pointing leaf bar, back blades (19B) is equipped with at impeller (19) back side between per two primary blades (19A), with gland packing (23) is housed in pump case (18) the bonded assembly seal receptacle (20), like this, the gland packing (23) that the back blades (19B) of impeller (19) is equipped with in seal receptacle (20) guarantees the sealing property of pump shaft (22), avoid mud to pass through the running part that impeller (19) enters the pump housing, influence driving efficiency, guarantee mud pump (3) maintainability, the impeller (19) that lambdoid primary blades (19A) makes high speed revolution at the strong vacuum power of the indoor generation of vortex flow of pump case (18) with the axial inspiration of mud, radially discharge, improve desilting efficiency data.Road wheel (8) is housed on hull of the present utility model (1), and manoevreability is good on land to make the utility model, has solved dredger land preferably and has shifted difficult problem.

The small-sized dredger crux that the utility model provides is to have solved the mud blockage problem, be that mud is axially to advance, radially go out in pump, runner is unimpeded, local loss reduces, and has solved route speed, tensile force for boat column and desilting concentration three and has coordinated, and reaches maximum power efficient, and solved the problem that difficulty is shifted on dredger land preferably, the footpath test, the complete machine performance has reached desilting concentration 80-90%(24 hour precipitation volume concentration), capacity rating 15m ³/ h, maximum delivery distance (80-120) m, dynamic efficiency 〉=3.4m ³/ kwh, complete machine quality 370kg, have in light weight, cost is low, shift on land and it is easy to maintenance to manipulate, desilting efficiency data is high, the advantage that continues to flow.
